AMSAT-UK to Provide FUNcube Lite Payload for Jovian-1 Satellite

AMSAT-UK has announced it will provide a FUNcube Lite payload for the Jovian-1 satellite, featuring a U/V FM voice transponder. Jovian-1, a 6U CubeSat, is being developed by Space South Central, a space cluster in the UK. The project is a collaboration between industry and academic institutions aimed at supporting the region’s space sector.

Jovian-1 is part of the JUPITER program, which stands for Joint Universities Programme for In-Orbit Training, Education, and Research. The program involves the universities of Surrey, Portsmouth, and Southampton and offers students direct experience in the space sector. JUPITER prepares participants for careers in space, with a focus on practical training in satellite design and operations.

The FUNcube Lite payload will collect telemetry data from the satellite’s subsystems, including radiation sensor readings and GPS information. The data will be transmitted to schools and colleges using the FUNcube data format. This will help track radiation levels across the satellite’s orbit and assess radiation effects on onboard electronics.

Students from Space South Central will design, build, test, and launch the Jovian-1 satellite. The satellite will use commercial S and X bands for its main communication, through a ground station at Surrey University. The FUNcube Lite payload will operate on UHF and VHF amateur radio frequencies. When not gathering telemetry, it can switch to a U/V mode FM voice transponder, enabling communication for radio amateurs.

The project emphasizes the role of regional space clusters in advancing the UK space industry. Space South Central represents over 170 space-related businesses in the region. The mission allows students to conduct satellite operations from the University of Surrey’s ground station, bridging academic study with hands-on experience.

More information about the Jovian-1 mission and the FUNcube Lite payload will be shared at the AMSAT-UK Colloquium on October 12-13, 2024. The event will provide detailed updates on the satellite’s development and its technical components, offering insights for anyone interested in amateur radio and satellite communications.

AMSAT-EA HADES-R and HADES-ICM planned for Q1 2025

AMSAT-EA has announced the upcoming launch of two new satellites, HADES-R and HADES-ICM, which will be made available to radio amateurs in early 2025. These satellites are set to replace the current HADES-D (SO-121) satellite in orbit. Unlike HADES-D, which transmits at a power level of 40mW, the new satellites will have variable transmission power, reaching up to theoretical 250mW when fully charged.

The HADES-R and HADES-ICM satellites, classified as 1.5p pocketQubes, will be launched by SpaceX on its Transporter-12 and Transporter-13 missions. The launches will utilize D-Orbit’s ION orbital transfer vehicle (OTV), with mission management provided by Alba Orbital, a Scottish company specializing in satellite launch solutions. As with previous AMSAT-EA projects, these satellites have been developed with the support of private companies and universities.

Both satellites will support a wide range of communications capabilities, including FM voice, FSK, FT-4, and FT-8 modes. They will also be equipped to handle AX.25/APRS communications at both 300 and 1200 bps. The uplink for the satellites will be in the VHF band, while the downlink will operate in the UHF band. Additionally, the satellites will transmit telemetry data, including status updates, voice messages, and CW messages. All communications will be managed through an SDR-based FM and FSK repeater, which will be available at all times, activated by squelch level without the need for a subtone.

In addition to their primary communications functions, both satellites will carry a scientific experiment from the Smart IR/Graphene Engineering Innovation Centre (GEIC) at the University of Manchester. This experiment will test a very low-power active radiator under space conditions. HADES-ICM has received sponsorship from IcMercury (Interstellar Communication Holdings), based in Florida, and will feature several challenge messages embedded within the FSK telemetry. While the HADES-R satellite has already been coordinated by the International Amateur Radio Union (IARU), HADES-ICM is still pending approval.

NASA Gears Up for Europa Clipper Mission to Jupiter’s Icy Moon

NASA is set to launch the Europa Clipper mission, a groundbreaking effort to explore Jupiter’s icy moon, Europa. Slated for liftoff as early as October 10, 2024, the spacecraft will be carried into space by a SpaceX Falcon Heavy rocket from Kennedy Space Center in Florida. The mission aims to uncover the mysteries of Europa’s hidden ocean and assess whether the moon could host conditions favorable for life.

Europa Clipper’s journey will take six years to reach the Jupiter system. Once there, it will enter an orbit around Jupiter, performing dozens of flybys of Europa. The spacecraft’s suite of instruments will probe beneath the moon’s icy shell to study its subsurface ocean. By mapping the moon and investigating its potential habitability, NASA hopes to shed light on one of the most intriguing questions in planetary science: whether life could exist on other worlds.

The mission is significant because Europa is thought to possess all the ingredients necessary for life. Beneath its thick ice lies a vast, salty ocean, which may contain more water than all of Earth’s oceans combined. The moon’s subsurface environment could offer the energy, liquid water, and organic compounds required to support life. Although Europa is smaller than Earth’s moon, its potential to harbor a habitable environment makes it a prime target for exploration.

To reach Jupiter, Europa Clipper will rely on two gravity assists. In 2025, it will pass within 1,000 kilometers of Mars to adjust its trajectory, followed by a close flyby of Earth in 2026. These maneuvers will boost the spacecraft’s speed and guide it toward the Jupiter system, where it is expected to arrive in 2030. Instead of orbiting Europa directly, the spacecraft will remain in orbit around Jupiter, occasionally dipping into the planet’s intense radiation field for close encounters with Europa.

Once in the Jupiter system, Europa Clipper will conduct over 40 flybys of Europa, approaching as close as 25 kilometers above its surface. The spacecraft’s instruments are designed to withstand the harsh radiation environment, with most being housed in a protective radiation vault. Each flyby will gather detailed data, providing new insights into the moon’s ice-covered ocean and the possibility of life beneath its surface.

The spacecraft’s science instruments include ice-penetrating radar to map Europa’s icy shell and magnetic sensors to confirm the presence of its ocean. High-resolution cameras and spectrometers will analyze the moon’s surface and search for water vapor plumes that may erupt from below. Although Europa Clipper is not officially a life-detection mission, it promises to transform our understanding of habitability beyond Earth.

Artificial Star Mission Aims to Help Unlock Secrets of the Universe

NASA is embarking on an ambitious mission that could reshape our understanding of the universe with the help of a small, human-made satellite. Researchers at George Mason University are leading a $19.5 million NASA-funded project to launch an “artificial star” into space. The goal of this satellite, once it reaches orbit, is to appear as a star to telescopes on Earth, allowing scientists to gather more precise data on stellar brightness. The mission could unlock critical insights into the age, size, and scale of stars, offering fresh clues about the expansion of the universe and even the potential for extraterrestrial life.

The so-called artificial star will be positioned in geostationary orbit, approximately 22,236 miles from Earth. While it won’t be visible to the naked eye, telescopes will be able to track the satellite as it moves at the same speed as Earth’s rotation, staying positioned over the U.S. Named in honor of the late astronomer Arlo Landolt, known for his work in stellar calibration, the satellite will spend its first year in space using advanced technology to monitor the brightness of millions of stars. This will allow astronomers to refine existing models for measuring stellar evolution and the universe’s expansion.

Equipped with a sophisticated array of lasers, the satellite will serve as a controlled reference point for researchers on Earth. It will enhance the accuracy of brightness measurements, providing data that cannot be gathered from ground-based telescopes alone. According to Peter Plavchan, the primary investigator of the Landolt NASA Space Mission at George Mason, this mission represents a breakthrough in how stars and even distant supernovae are studied. “Such measurements can only be achieved by a space-based orbiting artificial star,” Plavchan said.

The mission, part of NASA’s Pioneers program, marks a significant milestone for George Mason University. This is the university’s first time leading such a mission, with NASA providing oversight and key technical support. George Mason is collaborating with the National Institute of Standards and Technology and 10 other universities to develop the satellite, which will face significant engineering challenges in high orbit. “Our team will design, build, and integrate the payload,” said Peter Pachowicz, an engineering professor at George Mason. “It’s an incredibly exciting opportunity.”

One of the broader goals of the Landolt mission is to contribute to the search for habitable planets. By analyzing how stars influence planetary environments, the satellite could help scientists better understand where in the universe conditions might be suitable for life. Astronomers are particularly interested in so-called habitable or “Goldilocks” zones, where planets could have the right conditions—neither too hot nor too cold—to support liquid water, a key ingredient for life. Understanding how stars affect these zones is essential to identifying planets that may harbor life.

While the mission has the potential to revolutionize the field of astronomy, it also poses big challenges. Finding definitive evidence of life beyond Earth requires precise measurements of stellar properties, such as how much energy a star emits and how close a planet is to that star. “There are so many big questions in astronomy: How did we get here? Are there other planets like ours? Do aliens exist?” said Jamie Tayar, an astronomer at the University of Florida, a partner in the mission. With the launch of the artificial star planned for 2029, the team hopes to get one step closer to answering these profound questions.

AMSAT Ambassador Activities

AMSAT Ambassadors provide presentations, demonstrate communicating through amateur satellites, and host information tables at club meetings, hamfests, conventions, maker faires, and other events.

AMSAT Ambassador Clint Bradford, K6LCS, says,

Just completed presenting my satellite show to the Sandton Amateur Radio Club in South Africa – via Zoom. And what a marvelous group they are! Keith ZS6HI was my contact. Great questions throughout from the Zoom audience. From Keith: “Thank you very much Clint and Karen. Wonderful presentation. You did a lot of research and preparation to put a South African spin on the presentation and spent effort on learning about the SARL, Sandton Club and South African Amateur Radio community beforehand.” “SARL” is South Africa’s “ARRL.” And there is an active AMSAT Chapter there, too!

That was Presentation Number 175 … more are scheduled! Think a lively, informative, and fun presentation on working the “easy” satellites with minimal equipment would be appropriate for your club or convention?

+ NASA’s Voyager 1 spacecraft, which has been in space since 1977, recently experienced issues with its thrusters due to clogged fuel tubes caused by aging. The thrusters, which are essential for keeping the spacecraft pointed toward Earth, use liquid hydrazine that releases in puffs to adjust its orientation. Engineers discovered that one set of thrusters had become clogged with silicon dioxide from the spacecraft’s fuel tank, necessitating a switch to a different set. However, due to power and temperature constraints, turning on the replacement thrusters required careful planning. The team successfully activated non-essential heaters to warm up the thrusters, making the switch on August 27, 2024. This complex operation ensures Voyager 1 can continue its mission, providing valuable data from interstellar space despite its advanced age and limited power.

+ The International Amateur Radio Union (IARU) recently reached a milestone, processing its 1,000th satellite frequency coordination request. This achievement underscores the IARU’s essential role in managing radio frequencies for amateur satellites, ensuring optimal performance and minimal interference with terrestrial services. Since the late 1990s, the IARU’s Satellite Frequency Coordination Panel has collaborated with satellite developers and regulators to facilitate successful amateur communication and educational satellite missions. The rise of CubeSats and the drop in launch costs have increased the demand for careful spectrum management. The dedication of IARU volunteers and the global amateur radio community has made this possible, ensuring continued opportunities for education, communication, and scientific research. As Earth’s orbit becomes more crowded, the IARU’s work in frequency coordination will remain critical for future missions. (ANS thanks IARU for the above information)

+ NASA astronaut Tracy C. Dyson, along with Roscosmos cosmonauts Oleg Kononenko and Nikolai Chub, successfully returned to Earth on September 23, after landing in Kazakhstan aboard the Soyuz MS-25 spacecraft. Dyson spent 184 days aboard the International Space Station (ISS) as part of Expeditions 70 and 71, completing 2,944 orbits and covering 78 million miles. Chub and Kononenko, who spent 374 days in space, returned after an extensive mission spanning 5,984 orbits and 158.6 million miles. Notably, Kononenko set a record with over 1,111 cumulative days in space across five missions. The crew undocked from the ISS’s Prichal module before their parachute-assisted landing southeast of Dzhezkazgan, Kazakhstan. Following their recovery, Dyson returned to Houston, while Kononenko and Chub headed to Star City, Russia, for post-mission procedures. (ANS thanks SciTechDaily for the above information)

+ SpaceX is preparing for a historic test flight of its Starship megarocket, aiming to catch its Super Heavy booster using the “chopstick” arms of the launch tower. This innovative recovery method, practiced at the Starbase site in South Texas, could dramatically reduce refurbishment times compared to traditional landing methods. The company recently showcased these preparations, lifting the booster to its expected catch height. Starship’s fifth test flight, slated for late November 2024, follows previous launches where performance has steadily improved. Despite SpaceX’s readiness, regulatory delays from the FAA have pushed the launch timeline. SpaceX has expressed frustration with the regulatory process, citing concerns about the pace of environmental impact reviews and modifications assessments.

LabBook: Project TouCans on/off relay a bit further along

Over the weekend, KOTBTY and I got to spend more time moving the CW key relay inside Project TouCans and adding a power on/off latching relay. As you can hear and see in the video below, the latching relay is up and running! Thanks for Simon Willison for the Claude artifact that enabled me to easily package up the video below.


Ha, that's interesting! It's not so much a video packaging as a video thumbnail tool, which is of course what it said it was. Well, here's the video all bundled up into an iframe ready for your viewing—and listening—pleasure. I'll have to work with the gang on a version of the tool that outputs iframes soon.



What you can see in the video: the Darlington array has two control leads coming into it from the PICO-Ws GPIO 17 and GPIO 18 pins, (the orange and red wires respectively.) Now that we're using a latching relay, we need one control wire to latch the power on and a second wire to latch the power off. Positive rely coil power is attached directly to the latching relay, but the circuit through each coil to ground is broken by the Darlington array. When the Pico-W signals to the Darlington array to conduct for a fraction of the second, the appropriate relay coil, (either power-on or power-off), is energized and then the connection is latched by the internal latching magnets of the relay.

MESAT1 Telemetry and Testing-Update

The MESAT1 Command and Commissioning Teams wish to thank all that have routinely or even occasionally collected telemetry from MESAT1. Thanks to these reports, the teams are able to make informed and timely decisions about what/when/why/how to do next steps in collaborating with the satellite owners to help with their primary mission. Much is being learned about this new satellite–the University of Maine’s first Cubesat–and AMSAT’s linear transponder onboard. All of the lessons learned will help inform future missions that carry the Linear Transponder Module (or LTM) and the Golf series of satellites. Reports about transponder activities are very helpful, as well.

MESAT 1 [University of Maine]

Amateurs are encouraged to visit this link to see in detail all of the callsigns that have contributed to telemetry collection thus far. It’s a lot of stations, all around the world:
https://www.amsat.org/tlm/leaderboard.php?id=10&db=FOXDB&show=all&period=100

Please continue to collect telemetry! We continue to work on taking and downloading earth images from their cameras. In recent days, we are having the satellite send image blocks both in the mornings and evenings. We expect that to continue in the near future. The transmitter could be on for 5 mins, or perhaps even 10 mins, when over the East coast command stations. Every frame helps us to build an image. Testing is intermittent, but it seems to be more regular right now. When the images aren’t being transmitted, MESAT1 is in SAFE mode, sending a couple frames about every 2 minutes. These frames are very important too!

MESAT1 was in HEALTH mode, transmitting telemetry continuously, and the beacon setting is pretty strong as of 11:43z on 19 Sept 2024. The linear transponder was enabled at 0050utc on 20 Sept. 2024. Watch AMSAT-BB for announcements regarding MESAT1 status.

GreenCube (IO-117) Ceases Functioning Due to Radiation Damage

The GreenCube satellite, developed by S5LAB, has likely ceased functioning due to radiation damage. After a successful mission that exceeded expectations, the satellite is no longer responding to commands, and its onboard radio is believed to have been compromised by the harsh radiation environment in Medium Earth Orbit (MEO).

Approximately ten days ago, GreenCube experienced a reboot, and telemetry data from the event did not indicate any anomalies. However, the S5LAB team now suspects that the satellite’s radio was damaged, leading to the current communication blackout. MEO is notoriously challenging for satellites due to its high radiation levels, and GreenCube was not the only satellite affected. Several other CubeSats launched alongside it only lasted a few days, making GreenCube’s extended mission duration a remarkable achievement.

Despite ongoing efforts to send commands and reactivate the satellite, the team remains pessimistic about restoring GreenCube’s functionality. The satellite’s survival in the hostile MEO environment is seen as a testament to its robust design, but the likelihood of recovery is slim.

At this time, no successor to GreenCube is planned, primarily due to the infrequency of launch opportunities to MEO. Launches to this orbit are rare, which complicates the prospect of future missions.

In response to the satellite’s success and the interest it generated among radio amateurs, S5LAB has promised to host a webinar in collaboration with AMSAT Italia. The event will provide insights into the GreenCube mission, sharing the challenges and triumphs of the satellite’s journey. This is an opportunity for the amateur radio community to learn more about the satellite’s impact and the technical details behind its impressive mission.

While GreenCube’s operational life may have ended, its contributions to satellite technology and amateur radio will be remembered as a significant milestone.

Changes to AMSAT-NA TLE Distribution for 20 September

Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated daily in the first hour of the UTC day. New bulletin files will be posted immediately after reliable elements become available for new amateur satellites. More information may be found at https://www.amsat.org/keplerian-elements-resources/

No changes have been announced for this week.

+ Tracking sleuth Scott Tilley, VE7TIL, has discovered that the orbiter for China’s Chang’e-6 lunar sample return mission is now parked at the second Sun-Earth Lagrange (L2). After delivering the samples to Earth, the orbiter fired its engines to avoid reentering Earth’s atmosphere, setting off on a new trajectory. L2 is located approximately 1.5 million kilometers from Earth, directly on the opposite side of the Earth from the Sun. China’s space authorities have yet to provide an update on the orbiter and its plans. However, the Chang’e-6 orbiter’s voyage fits into a pattern of China using Chang’e spacecraft for extended missions as tests for future endeavors. (ANS thanks Space News for the above information.)

LabBook: Project TouCans Power and Keyer Relay Remoting

 One remotely controllable switch that Project TouCans has been missing is an on/off switch. Once the rig's up in the air, it's powered until we bring it bakc down or the battery goes dead. We're working on changing that. A few weeks ago after reading about Darlington arrays on a ham radio forum message I can no longer locate, we put a plan in place. K06BTY got our twow main comcponents soldered ont a board and we stepped away from the project for a few weeks. We're back and just about ready to go.

Here's what we have now


K06BTY installed our keyer relay dead-bug style using superglue below the single-pole double-throw power relay. We're using the Darlington relay pictured at the top of the column to protect the Pico-W from directly delivering current to the relay coils, an activity that can destroy at least the GPIO portion of the Pico-W, (ask me how I know.)

More updates soon. For step by step progress updates see TouCan's github page for this project.



Project TouCans: Rock Locked Station Operation

 Project TouCans is rock locked, meaning that it operates on a single frquency: 14057.4 kHz at teh moment. This leads to station operation that looks a bit different from most. Notice that while we do use the RBN, it's mostly as a wellness check for TouCans. For us to call a station, they have to be on frqueqncy, so we also use the tool shown in the terminal window to the left, rbn_telnet.py. We can start it with a signal range such as 

python3 rbn_telnet.py -b 14057 -e 14059

The tool then connects to the RBN's telnet feed and filters for only calls between the -b and -e arguments in kHz.

AMSAT 2024 President’s Club Membership Raise over $36,000 To-Date

AMSAT would like to recognize those members whose generous gifts to the AMSAT 2024 President’s Club help move its educational and engineering programs to fulfillment. President’s Club members have contributed over $36,000 to-date during the 2024 year. Frank Karnauskas, N1UW, AMSAT VP-Development comments, “It’s really gratifying to see AMSAT membership continue to support AMSAT projects during what some people consider to be ‘quiet years’ – those years following the retirement of some of our most popular satellites and the year or so before our next family of satellites are flight ready.

“In fact, things are far from quiet. AMSAT engineering teams for both Fox-Plus and the Golf-Tee are moving quickly so the wait for a new family of birds won’t be all that long. The ASCENT engineering team is also charging ahead with new payloads for packet and SSTV operation. And, to keep AMSAT in the game as satellite licensing becomes more strict, work on propulsion systems for CubeSat-class vehicles is benefitting from the experience of a fresh team of experienced aerospace engineers. A lot is happening behind the scenes.”

“If you collected any bin files during the past 5 days they can be uploaded too. If you are still experiencing errors. Please back up the session to a bin file, stop and start the dashboard and load the bin file. Then restart again if the upload works.

“We will continue to work on the UI over the next two days and it is likely that we will restore the ability to download WOD.”

Dave also remarks, “FC1 is now nearly 11 years old and is operating in low power telemetry mode with the transponder, in order to manage the battery capacity.

“We still encourage ground stations to attempt reception of the telemetry. If you have lost your registration details for your ground station please email operations@funcube.org.uk Please watch http://data.funcube.org.uk for updates and the new user interface.”

AMSAT-DL ERMINAZ Mission Postponed to 2025

On Monday evening, August 19, 2024, just a few weeks before the planned launch date of the ERMINAZ payload, Rocket Factory Augsburg (RFA) conducted a “hot fire” test of the first rocket stage at its launch site at SaxaVord Spaceport on the Shetland Islands, during which all 9 engines were ignited. Unfortunately, this resulted in a serious anomaly that led to the complete loss of the first rocket stage. The repair work, fault analysis, qualification and delivery of a new first rocket stage will take some time, so that RFA now officially expects a launch in 2025.

The Erminaz mission is a joint effort between AMSAT-DL, AMSAT-EA and the Libre Space Foundation, with each organization flying its own satellites and jointly using the PicoBus deployer developed by Libre Space in the ERMINAZ mission.

Examples of the payloads include UNNE-1 and MARIA-G 1.5P PocketQubes from AMSAT-EA in Spain. They are both based on the HADES-D (SO-121) hardware currently in orbit and provide a repeater service for voice and data communications in FM and FSK modes. They were developed and built by AMSAT-EA in collaboration with private sector companies and with the participation of universities and educational centers. Both satellites will provide licensed radio amateurs around the world with the ability to conduct FM and FSK QSOs, including FT modes such as FT-4 and FT-8 or AX.25/APRS. The satellites will also transmit telemetry with their status, voice messages and CW. Both satellites have the amateur radio special call sign AM1HAD.

For detailed information on this ambitious and collaborative mission including the capabilities of all the various satellites included in this project, go to https://amsat-dl.org/en/erminaz-mission-postponed-to-2025/.

Updated Software Available for NOAA Polar and Russian Meteor Weather Satellites

Tracking and downloading images from NOAA Polar and Russian Meteor weather satellites are an excellent way to introduce young persons to the world of amateur satellites and radio communications. True, they are not amateur radio satellites. But, they are loud and always on. Using a SDR dongle costing less than $50, a laptop computer that every kid already owns and free software, youth can get their first taste of tracking a satellite across the sky using a smart phone app, recording a downlink and printing out pictures of their own weather in real time. From there it is a simple jump to listening to voice communications and printing APRS packet conversations from the ISS – another easy-to-hear and predictable source of signals from space.

Historically, WXtoIMG has been the software of choice for the popular hobby of decoding NOAA APT weather satellite images with RTL-SDR and other SDRs. However, the software has unfortunately been abandoned by its authors for several years, and can now only be found on third-party websites which increases the possibility of downloading a virus.

Jacopo Cassinis, IU1QPT, author of SatDump, and Robin Slovacek, OK2AWO, for sharing their thoughts about switching to SatDump which now has full feature parity with WXtoIMG and additional features, too. SatDump is available on Windows, MacOS, Linux, and even on Android. Read their comments at https://www.rtl-sdr.com/.

An up-to-date guide for receiving APT pictures with SatDump can be found at https://www.a-centauri.com/articoli/noaa-poes-satellites-reception.

Also available to watch on the rtl-sdr website is a short video on setting up a simple v-dipole for NOAA weather satellite reception with the SDR-Dongle. (The video uses the out-of-date WXtoIMG software but the overall procedure for setting up the station is usable.) If you need to get more ideas on weather satellite picture reception, just go to YouTube and search “NOAA weather satellite reception” and be prepared to watch several hours worth of useful videos.

Copying NOAA weather satellites is easy to do and a fun way to introduce youngsters to space communications. It could be the first step to getting that Technician ticket!

Changes to AMSAT TLE Distribution for September 6, 2024

Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated daily in the first hour of the UTC day. New bulletin files will be posted immediately after reliable elements become available for new amateur satellites. More information may be found at https://www.amsat.org/keplerian-elements-resources/.

  • The following satellite has been removed from this week’s AMSAT TLE distribution:

RoseyCubesat 1 NORAD Cat ID 56212 Decayed from orbit on or about 01 September 2024

Satellite Shorts From All Over

  • Yaesu has announced the upcoming FTX-1F HF/6/144/440 portable transceiver, presumably a replacement for the FT-816/817 series of transceivers that were very popular among satellite operators. The transceiver is said to have two independent SDR receivers that provide simultaneous dual-band operation, whether in the same or in different bands. (Editor’s note: This does not necessarily mean that the transceiver will operate in full duplex mode.) It will provide 6W of power output with the included 5670mAh Lithium-ion battery pack or up to 10W with external power. Average CW/SSB operating time in the VHF/UHF bands is quoted as up to 8 hours. SSB, CW, AM, FM and C4FM operation is available. USB ports support CAT operation, audio input/output and TX control. The FTX-1F has not been formally been released for sale in the United States but should be available early 2025. [ANS thanks Yaesu for the above information.]
  • JAXA officially ended the mission of SLIM, the country’s first Moon lander, last week. Originally only expected to operate for a single lunar day and then feared to be doomed after it landed in the incorrect orientation after losing an engine bell, the mission managed to survive 3 lunar nights and complete all pre-mission success criteria. SLIM is the first lunar lander to successfully perform a “pinpoint” landing, arriving within 10 meters of its selected landing site. [ANS thanks The Orbital Index for the above information.]
  • The average age of a GPS satellite is now 13 years, with half of them exceeding their designed lifespan. The USA-132 satellite broke the record for the oldest GPS satellite in history, having completed 27+ years in operation. While the record is an indicator of the reliability and robust engineering of the GPS satellite, it also means that the service still relies on hardware built in the 1990s. 31 GPS satellites are in operation today, down from 36 in 2016. The GPS system was primarily designed for military purposes but was opened up to wide-scale civilian use in 1983. Since then, GPS has grown into one of the most widely used services in the world, with billions of people using GPS on a daily basis today. The overall GPS network still works well. But the aging satellites, coupled with the delays in the launch schedule for new satellites, threaten its competitive edge as international rivals bring into service their own GNSS systems and private companies develop alternatives.

Signal Strength and Reach from the Bay TouCans and the W6CSN KH-1

 Immediately after getting TouCans back on the air a few days back,  I was presented with the opportunity to see a few things about how the rig works and whether or not its antenna angle might be an issue.

W6CSN shared a post about his POTA outing with his KH-1 on the same day. I inquired as to the power  he used. He replied that he was running 4 Watts into his EFHW antenna from San Pablo Bay National Wildlife Refuge, US-0212.

 I have, for a long time, wanted to find out if the Rocky Mountains barrier faced by TouCans during the day is a feature of the rig, the ionospher, or the rig's antenna angle, (sloping down a hill in the backyard.) Based on Matt's QSO report and RBN spots vs. my RBN spots for the day, it looks like the barrier might be an ionosphere thing:


Matt's QSOs on 9/2/2024

Notice the cutoff  with no QSOs past Utah and Arizona. That's what I saw during the same day for TouCans on the RBN:

Project TouCans RBN Spots 15:00 UTC to 22:00 UTC


Here, you can see that only one spot made it out as far as as th Kansas/Missouri border. Also note that the rig was spotted at 34 dB, (34 dB into anywhere is a hefty signal for TouCans), in LA which fits with W6CSN remarking about his unusal QSOs to the South. 

The ionospheric causation idea holds up looking at W6CSN's RBN spots for the same day 24/09/02:


Of course, as with all things ionosphere and HF, I don't have a conculsive answer, there are too many variables. I'm going to go down a not strictly robust path here and say that the difference in antenna types, (kinda vertical EFHW vs. dipole), and sites,  (plain at sea level at San Pablo Bay vs. hillside in SF proper a few miles to the South), make the ionosphere on the 2nd more of a likely culprit for the similar results.

Why was the ionosphere doing the things it did? I don't know yet, but I'll keep you posted.  


 

Lab Book: Hunh, Resonant Length Does Matter

I mentioned earlier that Project TouCans is back on the air. It's also on the air with a stronger signal than it had two weeks ago. The difference?


That's it! That's the whole thing. Notice that the wire, which is coming apart and needs to be replaced, is wrapped onto the insulator with only about two or three inches of itself. For the last several weeks, I've been wrapping it with between six and seven inches of itself. Going back to the shorter wrap immediately led to more signal! I guess resonant dipole antennas are really resonant!




Project TouCans Flies Again!

 Project TouCans is back up and running! The rig just stopped dead in its tracks during the NAQCC Sprint a few weeks back, and that was that. After two hours of debug and soldering yesterday, it's back.

A few things of note:

The battere was completely dead. The imuto power supplies TouCans uses hold their charge for weeks, so I'm guessing this was the number one issue. But! The battery didn't do it's usual buck supply hum into the radio, (hence me not realizing it was even close to being out of juice.) 

The lack of buck supply hum might have been precipitated by the second issue I found. The audio output wire was severed within its insulation. A DC ohmmeter check indicate that there was an open circuit. I'm wondering though, if the wires were close enough together in the insulation if they weren't capactatively coupled, and therefore still producing sound and providing a bit of a filter. I replaced the wire in question, so we may never know. Here are the spots for the rig so far this morning. No backyard QSOs yet.

AMSAT Mail Alias Service to End — FINAL NOTICE!

A long-standing member service, the AMSAT Mail Alias Service was scheduled to end on August 31, 2024, but a day or two of grace period has been added.

Members should understand that the email alias service, the news and bulletin board subscription lists and the membership portal are three separate systems.

Persons using the Mail Alias Service should immediately migrate to a different email account so they do not lose receipt of personal emails. Notify your friends and business accounts of the change.

Persons wishing to continue to receive AMSAT News Service Weekly Bulletins and AMSAT-BB posts or official messages from AMSAT itself should update their subscription addresses at https://mailman.amsat.org/

Members are especially asked to make sure they are NOT using a callsign@amsat.org as their registered email address in the AMSAT membership portal. Members can easily change their registered member email address by logging into the portal and updating their profile at https://mailman.amsat.org/.

A mail alias on AMSAT.ORG permitted people to send an email to members without knowing their actual internet email address. They just needed to know their amateur radio callsign.

Unfortunately, the unchecked rise in domain name hacking and email account high-jacking has made it impossible to sustain this service at a cost-effective level. The number of callsign@amsat.org email accounts that had been hijacked and converted to zombie spam accounts over the years had led many internet service providers and gateway centers to ban all @amsat.org email addresses, including those business accounts of AMSAT officers and officials. The tireless efforts of AMSAT’s all volunteer IT staff has worked for years to repair much of the damage, but AMSAT still get complaints from members who are not getting their personal emails, ANS bulletins or AMSAT-BB posts because of persistent delivery problems.

It has come to the point where the AMSAT volunteer IT staff can no longer keep up with the maintenance requirements to keep the alias mail list clean and to work with email gateways to remove blocks. And, after considerable investigation into alternative paid email services, AMSAT leadership decided that the money required to keep an email alias system alive would be better spent on building and flying satellites for its members.

Japanese Company Takes First Step Toward Removing Space Junk

There are more than 2,000 mostly intact dead rockets circling the Earth, but until this year, no one ever launched a satellite to go see what one looked like after many years of tumbling around the planet.

In February, a Japanese company named Astroscale sent a small satellite into low-Earth orbit on top of a Rocket Lab launcher. A couple of months later, Astroscale’s ADRAS-J (Active Debris Removal by Astroscale-Japan) spacecraft completed its pursuit of a Japanese rocket stuck in orbit for more than 15 years.

ADRAS-J photographed the upper stage of an H-IIA rocket from a range of several hundred meters and then backed away. This was the first publicly released image of space debris captured from another spacecraft using rendezvous and proximity operations.

Astroscale’s ADRAS-J spacecraft captured these views of the H-IIA rocket upper stage on July 15. [Credit: Astroscale]

Since then, Astroscale has pulled off more complex maneuvers around the H-IIA upper stage, which hasn’t been controlled since it deployed a Japanese climate research satellite in January 2009. Astroscale attempted to complete a 360-degree fly-around of the H-IIA rocket last month, but the spacecraft triggered an autonomous abort one-third through the maneuver after detecting an attitude anomaly.

ADRAS-J is the first mission to approach a piece of space debris, which comes with more challenges. The H-IIA upper stage lacks laser reflectors and targeting aids that would help an approaching spacecraft navigate its way closer.

A few years ago, the Japan Aerospace Exploration Agency (JAXA) cinched a public-private partnership with Astroscale to demonstrate technologies the private sector could use to remove large pieces of space debris littering low-Earth orbit. The same robotic technologies could also apply to satellite servicing or refueling missions.

With more financial assistance from JAXA, Astroscale is developing a follow-on mission called ADRAS-J2 to dock with the same H-IIA rocket visited by the ongoing mission, then steer it on a trajectory to reenter the atmosphere. Astroscale hopes a successful demonstration of this capability on the ADRAS-J2 mission will lead to more contracts from commercial or government operators to remote large pieces of space junk from orbit.

An H-IIA upper stage similar to the one visited by Astroscale’s demo mission broke apart in 2019, creating more than 70 new debris fragments in low-Earth orbit. A predicted close flyby by one of the pieces from the H-IIA upper stage prompted the International Space Station to fire its engines to move out of its path in 2020.

Halibut Electronics Releases New EggNOGS Kit for Satellite Antennas

Halibut Electronics has announced the release of its latest product, the EggNOGS kit, designed to facilitate the construction of Egg Beater antennas. This kit is aimed at amateur radio enthusiasts and satellite operators who wish to enhance their communication capabilities, particularly with the SatNOGS network. Priced at $79.00, EggNOGS is available for purchase through Halibut Electronics’ website at https://electronics.halibut.com/product/eggnogs/.

The EggNOGS kit is engineered to address the complexity of building Egg Beater antennas, which are known for their use in satellite communications. The kit includes a range of specialized components that are not typically available at local hardware stores. These components feature a band-specific phasing board that creates a 90-degree phase shift, a critical element in the construction of effective quadrature-fed antennas.

Currently, the EggNOGS kit supports several frequency bands: 137.5MHz, 145.9MHz, 388.0MHz, 401.0MHz, and 436.5MHz. However, due to high demand, the kits for the 137.5MHz and 145.9MHz bands are temporarily out of stock and are expected to be back in inventory by August 28th. Customers can place back orders for these bands in the interim.

The EggNOGS kit is designed to be versatile, compatible with various types of quadrature-fed antennas beyond just Egg Beaters. It can be used with turnstiles, helicals, and other balanced VHF/UHF antennas. Additionally, it works with any radio system, including low-power transmitters, making it a flexible option for a range of communication needs.

Antenna closeup [Credit: Halibut Electronics]

The kit includes essential parts such as circuit boards for signal routing and phasing, a common mode current choke, and stainless steel mounting hardware. Builders will need to source additional materials, such as a section of PVC pipe and materials for the aerial loops and ground plane, from local hardware stores. The default feed point connector is SMA, but there is an option to upgrade to BNC or Type-F connectors.

The EggNOGS kit is capable of handling moderate transmit power, with the upper limit still being determined but expected to range between 15W and 50W. The kit is confirmed to handle up to 10W without issues. Halibut Electronics invites feedback from users who may need phasing boards for additional frequencies not currently offered, with the possibility of expanding the product line based on customer demand.

Due to the significant damage to the RFA’s One launcher stage during the static firing test at SaxaVord’s spaceport in the Shetland Islands, Scotland (UK) on August 19th, AMSAT-EA’s UNNE-1 and MARIA-G satellites launch will be delayed.

They were originally planned for launch on September 30th, and now it is not expected before 2025. Video of the BBC’s coverage of the incident is available here:
https://www.youtube.com/watch?v=DgEn6-8ekJQ

UNNE-1 and MARIA-G are both based on the currently orbiting HADES-D (SO-121) hardware, providing a repeater service for voice and data communications in FM and FSK-derived modes. They have been designed and built by AMSAT-EA together with private sector companies and with the collaboration of Universities and educational centres.

Both satellites will offer licensed radio amateurs around the world the opportunity to make FM and FSK QSOs, including FT modes, such as FT-4 and FT-8, or AX.25/APRS. The satellites will also transmit telemetry with their status, voice messages and CW.

UNNE-1 includes an Arduino-based board with software from Nebrija University of Madrid. The students have developed a small decoding game with a space story as a background. The satellite sends a clue each week in its FSK telemetry so that radio amateurs can solve the challenge. This game will be detailed on the AMSAT EA website and on the Nebrija University one.

MARIA-G also includes two CW reception games/challenges implemented by students from the María Guerrero high school in Collado Villalba, also from the region of Madrid.

One of the games consists of receiving the coordinates of a significant place on Earth (for example a city, a monument…) and the other about receiving a code that will correspond to a question about Science. Both games will have a dedicated web page.

MARIA-G also includes a small experiment, developed by the Fraunhofer-Gesellschaft research center in Germany. It consists of a proof of concept for the transmission of a TS-UNB waveform from a low Earth orbit. Therefore, it will transmit a TS-UNB message according to the ETSI-TS-103-357 standard. It is intended solely as a research and development project with no commercial intention.

The ITU modulation classification would be 100K W2DWW but the bandwidth will be reduced. The operation of this experiment will be carried out by AMSAT-EA.

The UNNE-1 and MARIA-G satellites are part of the Erminaz mission, a joint effort of AMSAT-DL, AMSAT-EA and LibreSpace Foundation, each organization flying its own satellites and using LibreSpace’s PicoBus deployer.

The mission management with the German Space Agency (DLR) and the launcher (RFA), as well as with the UK authorities, has been carried out jointly, with AMSAT DL leading it.

Paul D. Graveline, K1YUB, Silent Key

With heavy hearts, AMSAT and The AMSAT Journal mourn the passing of Journal assistant editor, Paul D. Graveline, K1YUB, on August 19, 2024.

Paul served as an assistant editor for the past seven years, starting with the July/August 2017 issue. In addition to his editing and authoring contributions to the Journal, Paul also served as an active member of the CubeSatSim Educational Materials Team for AMSAT’s Educational Relations program.

Here is how Paul described his ham radio exploits:

“Like many future hams in the 1960s, I became interested in radio by listening to shortwave stations on my grandfather’s old huge Philco radio.

“In 1960, I got a Hallicrafters S120 short wave receiver for Christmas, and I was hooked. A year later, K1DEN got me interested in ham radio. I was issued KN1YUB as a novice, and in 1963, I upgraded to General and K1YUB, which I still use today. Most of my ham operating has been using CW.

“By 1973, I passed my Advanced and Extra which required 20 wpm skills.

“In the 1980s, I worked and taught Novice and General license courses at Tufts Radio in Medford, MA. My time at Tufts included numerous ham conventions from Denver to Clearwater.

“Along with K1TW, I helped reestablish the shortwave focused Boston Area DXers which met on the third Friday of every month. Nearly 35 years later, we still do!

“More recently, I have been spending time in activities to support ham radio.

“For a number of years, I’ve been an Assistant Editor for The AMSAT Journal as well as being engaged, along with KU2Y, KD2XS , KK6NOW and WD6DRI, on an AMSAT project developing the CubeSat Simulator as a learning tool.

“I began following the space weather bulletins from Dr. Tamitha Skov, WX6SWW, better known as “The Space Weather Woman,” a few years back and now am a member of her steering committee, as well as being the Coordinator for her new Super Community project with the objective of sharing space weather knowledge across stakeholder communities like Aurora Chasers and Ham Radio operators. I did a cover story of Dr. Skov in The AMSAT Journal.”

Paul’s good humor, dedication, enthusiasm and many contributions to AMSAT and the larger amateur radio community will be greatly missed.

Satellite Shorts From All Over

+ The FUNcube Data Warehouse will be going off line on Saturday, August 31, as it transitions to a new server. The service may be down for about three days as the team has to migrate the large amount of data collected over 11 years and ensure that the service is running correctly. The dashboards will catch up if they are left connected, once the service comes on line. The team will probably turn on the collection service before the UI so that there is not to much data loss. (ANS thanks Dave Johnson, G4DPZ, of the FUNcube Team for the above information.)

+ NASA will return Boeing’s Starliner to Earth without astronauts Butch Wilmore and Suni Williams, KD5PLB, aboard the spacecraft, the agency announced last week. The uncrewed return allows NASA and Boeing to continue gathering testing data on Starliner during its upcoming flight home, while also not accepting more risk than necessary for its crew. Wilmore and Williams, who flew to the International Space Station in June aboard NASA’s Boeing Crew Flight Test, have been busy supporting station research, maintenance, and Starliner system testing and data analysis, among other activities. They will continue their work formally as part of the Expedition 71/72 crew through February 2025, and will fly home aboard a Dragon spacecraft with two other crew members assigned to the agency’s SpaceX Crew-9 mission. Starliner is expected to depart from the space station and make a safe, controlled autonomous re-entry and landing in early September. (ANS thanks NASA for the above information.)

+ NASA astronaut Nick Hague, KG5TMV, and Roscosmos cosmonaut Aleksandr Gorbunov will launch no earlier than Tuesday, Sept. 24, on the agency’s SpaceX Crew-9 mission to the International Space Station. NASA astronauts Zena Cardman, KJ5CMN, and Stephanie Wilson, KD5DZE, previously announced as crewmates, are eligible for reassignment on a future mission. The updated crew complement follows NASA’s decision to return the agency’s Boeing Crew Flight Test uncrewed and launch Crew-9 with two unoccupied seats. NASA astronauts Butch Wilmore and Suni Williams, KD5PLB, who launched aboard the Starliner spacecraft in June, will fly home with Hague and Gorbunov in February 2025. (ANS thanks NASA for the above information.)

+ The U.S. National Science Foundation National Radio Astronomy Observatory (NSF NRAO), and its administrator Associated Universities, Inc.

ISRO Successfully Launches SSLV-D3, Deploys EOS-08 and SR-0 Demosat

The Indian Space Research Organisation (ISRO) successfully launched its third and final developmental flight of the Small Satellite Launch Vehicle (SSLV-D3) on August 16, 2024. The launch, conducted from the Satish Dhawan Space Centre in Sriharikota, India, placed two satellites, EOS-08 and SR-0 Demosat, into orbit, marking the completion of the SSLV’s development phase. This achievement enables the rocket’s operational use by Indian industry and NewSpace India Limited (NSIL).

The primary payload, EOS-08, is an Earth observation satellite developed by ISRO’s U R Rao Satellite Centre. The satellite was placed into a 475-kilometer low Earth orbit about 13 minutes after liftoff. EOS-08 is equipped with three advanced payloads: the Electro Optical Infrared Payload (EOIR), the Global Navigation Satellite System-Reflectometry payload (GNSS-R), and a SiC UV Dosimeter. These instruments will support a variety of Earth and atmospheric monitoring tasks, including disaster management and environmental surveillance. EOS-08 also features several new technologies, including an integrated avionics system and flexible solar panels, which will be demonstrated during its mission.

The secondary payload, SR-0 Demosat, developed by Space Kidz India, is a 0.2kg CubeSat designed for educational and amateur radio purposes. Deployed into the same orbit as EOS-08, SR-0 Demosat is equipped with an Inertial Measurement Unit (IMU) and a LoRa digipeater. The satellite’s mission includes raising awareness about amateur radio and nano satellites among students, transmitting health telemetry, and serving as a Digital Packet Store and Forward System for radio amateurs worldwide. Additionally, SR-0 Demosat will act as a demonstration unit to qualify a new CubeSat deployer, reflecting Space Kidz India’s innovative approach to space technology.

Space Kidz India, which developed SR-0 Demosat, has a history of launching educational satellites. The SR-0 Demosat continues this tradition, serving both educational and amateur radio communities. Operating on a 437.400 MHz downlink, the satellite supports various digital communication modes, including 9k6 FSK AX25, 4FSK SSDV, and 38k4 LoRa. This allows radio amateurs globally to engage with the satellite and collect valuable data. SR-0 Demosat’s telemetry dashboard can be found on the SatNOGS website: https://db.satnogs.org/satellite/WZIT-9333-7102-4860-3049.

SpaceX Transporter-11 Launches 116 Satellites, Including OreSat0.5

SpaceX successfully launched 116 payloads aboard its Falcon 9 rocket as part of the Transporter-11 rideshare mission on August 16, 2024. The launch occurred at 11:56 a.m. PDT from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Base in California. This mission is the latest in SpaceX’s series of rideshare launches, which provide small satellites from various countries an opportunity to reach orbit without needing dedicated launch vehicles. Following stage separation, the Falcon 9’s first-stage booster successfully returned to Landing Zone 4, marking its 12th flight and 20th landing at LZ-4.

Transporter-11 carried a diverse range of payloads, including satellites from Japan, Chile, the United Kingdom, and Australia. Among the Australian payloads were three satellites launched by the Australian Space Agency: Kanyini, Waratah Seed-1, and Cuava-2. Waratah Seed-1, a 6U CubeSat, hosted multiple payloads, such as the Perovskites in Orbit Readiness Test (PORT-2), the Submillimeter Particle Detection System (SPaDeS), and Spiral Blue Space Edge-1 (SE-1), showcasing the collaborative nature of this mission.

Oregon also had a key payload on Transporter-11 with the launch of OreSat0.5, the state’s second satellite. Developed by the Portland State Aerospace Society (PSAS) at Portland State University, OreSat0.5 is a 2U CubeSat designed to demonstrate two critical systems: the attitude determination and control system (ADCS) of the modular OreSat bus and the Cirrus Flux Camera (CFC), which uses short-wave infrared (SWIR) technology. Deployed into a 510 km sun-synchronous low Earth orbit, the satellite began transmitting its first data beacons just 16 minutes after deployment, marking a significant milestone for the Portland State Aerospace Society team.

OreSat0.5’s mission includes testing an open-source ADCS designed for precise antenna and camera pointing on amateur radio satellites, and demonstrating the “DxWiFi” S-band 802.11b bidirectional radio system for high-speed (1 Mbps) communication. Additionally, it aims to provide openly published flight performance data, including power and thermal characteristics, to support the development of cost-effective, scalable satellite systems. Telemetry data from OreSat0.5 can be received on 436.500 MHz and decoded using 9600 baud GMSK with DK3WN’s GetKISS+ v.1.4.2 software. The telemetry dashboard is viewable on the SatNOGS website: https://db.satnogs.org/satellite/DKCD-1609-0567-7056-3922.

Planet Labs PBC, a California-based company, contributed 36 SuperDove Earth-imaging satellites to the mission, along with the Tanager-1 hyperspectral satellite. Tanager-1, developed in collaboration with the Carbon Mapper Coalition and NASA’s Jet Propulsion Laboratory, is designed to detect methane and CO2 emissions from space. This capability will enable precise monitoring of emissions from individual facilities, such as gas pipelines and coal mines, thereby enhancing efforts to combat climate change.

The mission also marked a significant achievement for Exolaunch, the satellite deployment company responsible for integrating 42 of the 116 satellites on the Transporter-11 mission. This launch was Exolaunch’s 30th successful integration, representing more than two dozen companies. Exolaunch CEO Robert Sproles expressed gratitude to their customers and SpaceX, emphasizing the importance of collaboration and innovation in the success of these missions.

Polaris Dawn Set for Historic Launch and First Commercial Spacewalk

The private astronaut mission Polaris Dawn is poised for launch on August 27, 2024, with a groundbreaking objective: the first commercial spacewalk. The four-member crew, consisting of Anna Menon, Scott Poteet, Jared Isaacman, and Sarah Gillis, arrived at the Kennedy Space Center on August 19 to finalize preparations. This mission, the first of the Polaris program, marks a significant step in commercial space exploration and is set to launch aboard a SpaceX Crew Dragon atop a Falcon 9 rocket from Launch Complex 39A.

Scheduled to last five days, the Polaris Dawn mission will propel the Crew Dragon spacecraft to altitudes reaching 1,400 kilometers, the highest for a crewed mission since Apollo 17 in 1972. The mission’s objectives are multifaceted, including testing laser intersatellite links with SpaceX’s Starlink satellites and conducting 40 experiments. However, the highlight will be the spacewalk, a historic first for a private mission, and the first from a Crew Dragon spacecraft. The spacewalk will involve all four astronauts, with two emerging from the hatch in new SpaceX-developed extravehicular activity (EVA) suits for a brief yet pivotal two-hour spacewalk.

Jared Isaacman, the billionaire backing the Polaris program and commander of Polaris Dawn, emphasized the importance of the spacewalk during a press conference after arriving at KSC. “The idea is to learn as much as we possibly can about this suit and get it back to the engineers to inform future suit design evolutions,” Isaacman stated. The spacewalk is scheduled for flight day three, with preparations beginning shortly after launch. The crew will undergo a prebreathing protocol to adjust the cabin’s atmospheric pressure and increase oxygen levels, a process essential for the EVA.

SpaceX engineer Sarah Gillis, serving as a mission specialist, detailed the crew’s rigorous preparations. On flight day two, the astronauts will don the EVA suits for mobility tests inside the spacecraft. During the spacewalk, two astronauts, referred to as EV1 and EV2, will take turns exiting the spacecraft for approximately 15 to 20 minutes each. Isaacman noted that while the idea of a free-floating spacewalk was considered, the crew will instead perform a “hands-free” demonstration with their feet securely attached to the spacecraft’s mobility aids, underscoring the mission’s cautious approach.

The mission’s development has been intensely focused on the spacewalk and the associated EVA suits. “The EVA probably makes up the majority of the development for Polaris Dawn,” Isaacman said, acknowledging the inherent risks. SpaceX vice president Bill Gerstenmaier, formerly of NASA, confirmed that extensive safety protocols have been implemented. He mentioned a recent issue where engineers identified and resolved a static electric discharge risk, ensuring the crew’s safety during the spacewalk.

Polaris Dawn’s mission profile includes a launch window between 3:38 and 7:38 a.m. Eastern on August 27, carefully chosen to minimize risks from micrometeoroids and orbital debris. After reaching an initial orbit, the spacecraft will ascend to 1,400 kilometers before lowering to 700 kilometers for the spacewalk. The mission will conclude with a demonstration of Starlink capabilities on flight day four, followed by reentry on day six. As the first of three planned missions under the Polaris program, Polaris Dawn represents a significant leap forward in commercial spaceflight, setting the stage for future endeavors, including a potential crewed Starship launch.

Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated daily in the first hour of the UTC day. New bulletin files will be posted immediately after reliable elements become available for new amateur satellites. More information may be found at https://www.amsat.org/keplerian-elements-resources/.

This week there are no additions or deletions to the AMSAT TLE distribution.

Satellite Shorts From All Over

+ Russia successfully launched its 89th Progress cargo spacecraft, Progress MS-28, to the International Space Station (ISS) on August 15, 2024. The uncrewed spacecraft lifted off from the Baikonur Cosmodrome in Kazakhstan aboard a Soyuz rocket at 0320 UTC. Carrying nearly three tons of food, scientific equipment, and other supplies, the spacecraft autonomously docked with the ISS on August 17 at 0553 UTC, connecting to the rear port of the Zvezda service module. This docking occurred just days after the previous cargo spacecraft, Progress MS-26, was deorbited on August 12 following its six-month mission. With its arrival, Progress MS-28 joined two other freighters, including Cygnus NG-21, and three crewed spacecraft already at the ISS. The successful mission continues Russia’s long-standing contribution to ISS resupply operations. (ANS thanks Mike Wall, Space.com, for the above information)

+ The European Space Agency’s Jupiter Icy Moons Explorer (Juice) mission is making headlines with its dual gravity assist maneuver this week. After a successful flyby of the moon on August 19, 2024, Juice passed Earth on August 20, 2024, marking the first-ever lunar-Earth double flyby. This maneuver uses Earth’s gravity to adjust Juice’s trajectory, setting it up for a flyby of Venus in August 2025 and ultimately aiming for Jupiter’s orbit by July 2031. The spacecraft’s two cameras are capturing and sending images back to Earth, while mission operators are closely monitoring the high-risk maneuver to ensure precision. With Jupiter being nearly 500 million miles away, this gravity assist strategy allows Juice to conserve fuel and carry a variety of scientific instruments. The mission’s success relies on careful navigation and timing, as any deviation could jeopardize its ambitious goals. (ANS thanks Ashley Strickland, CNN, for the above information).

+ Space is hard: NASA’s BurstCube, which deployed from the ISS in April, is a 6U CubeSat that detects gamma rays from short gamma-ray bursts, likely caused by neutron star collisions. BurstSat, unfortunately, lost one of its magnetorquers during commissioning, along with one solar panel that did not fully deploy. The team has been able to continue the satellite’s mission by compensating for the malfunctioning equipment through the use of a Sun-pointing configuration. But due to these failures, the mission will likely reenter sooner than expected, around the end of 2024. [Before complaining about the failure of your favorite HamSat, consider that even NASA has issues!] (ANS thanks The Orbital Index for the above information.)

+ The FCC has granted SpaceX permission to upgrade its first-generation Starlink satellites with second-generation technology, aiming to enhance broadband quality for its users. This upgrade is expected to improve service, especially in polar regions, by using advanced beam-forming and digital processing technologies. SpaceX initially launched first-generation satellites in 2019 and applied in 2023 to integrate the new technology. Despite pushback from Dish Network over potential interference issues, the FCC dismissed these concerns, supporting SpaceX’s plans to optimize spectrum use and increase network capacity. SpaceX will replace the older satellites with upgraded ones as they reach the end of their operational period, rather than de-orbiting them rapidly. The overall goal is to provide more robust service to underserved areas across the country. (ANS thanks Michael Kan, PCMag, for the above information).

Project TouCans Antenna Feed Redesign

 Halibut Electronics is working on a new satellite antenna kit!

This is kinda cool for two reasons, first because we've recently started attending the high altitude balloon meetups at Noisebridge. Satellite antennas came up during one of the meetings.

More tactically importanly though, the EggNogs docs inspired what be a better tuna can feedtrough for Projct TouCan's antenna! For notes, here's my original EggNogs documentation review reply:


The documentation looks great so far! I've made it to page 17/22. One thing:
 
 
For those of us with partners heavily into fountain pens, those of us who like to print out manuals on JIS B5 paper and then store them in Kokuyo Campus binders, page numbers in the table of contents would be very cool. (I know, I know, such a niche group :) )
 
Mostly though, I wanted to thank you for jogging my memory into a, (I hope), better solution for Project TouCans antenna ports. At present, they're inverted bananna plug posts. Banana plug screw terminals are tiny, and therefore somewhat problematic in outdoor environments. Here's an idea of how tiny
 

 

 
Suspending a two pound rig 6 meters up, eventually the screw threads begin to strip. We stuck with banana plugs though because the insulator around the conductor makes them perfect for mounting in a tuna fish can. Yes, I've read about how Yagis and dipoles are balanced and therefore have 0 volts across the antenna center, so theoretically you don't need insulators, but TouCans frequently hangs at angles to the ground and/or very close to the ground,  so, insulators.
 

 
Anyhow! The last figure on page 17, the one with the cool weather-proof washer, reminded me that gromets exist! With the correct sized gromet, we can put any size bolt pointing upward as an antenna connector.
 

 
And, even better still, we can source them from our local hardware store at the bottom of the hill!
 
Thanks Mark!

ROBUSTA-3A in Orbit

When the long-delayed inaugural launch of the European Space Agency’s (ESA’s) new Ariane 6 rocket finally occurred on July 7, it suffered an upper stage failure that left some payloads in the wrong orbits. Fortunately, before the anomaly developed, the Ariane 6 successfully deployed ROBUSTA-3A, a satellite with an amateur radio payload. The target was a 580 km circular orbit with an inclination of 96 degrees.

ROBUSTA-3A (a.k.a. “Méditerranée”) is a 3U cubesat, designed and built by students and faculty of Université de Montpellier in southern France. Over a decade in development, involving around 300 students from the University of Montpellier and all over the world, ROBUSTA-3A will be its seventh satellite developed entirely in-house, having learned much from the development and launch of smaller ROBUSTA-1U satellites. The project has offered hands-on training, engineering and scientific experience to the next generation of space engineers and researchers.

The satellite’s primary mission is weather observation, specifically to track “Cevenol events.” These are intense storms and incredibly heavy rains that cause extensive flooding, often in the form of flash floods, that hit the plains and the foothills of southern France. Once considered “100-year storms,” they have been occurring with greater frequency due to global climate change. Most of the weather data is downlinked on a commercial S-band microwave frequency.

“If the data we will be collecting improves the geographic and temporal accuracy of weather forecasts for cévenol events, it would help authorities give early warning to the population and allow rescue services to better target the areas at risk,” explains Romain Briand, assembly integration and testing manager at the University Space Center of Montpellier.

Robusta-3A under development by Centre Spatial Universitaire de Montpellier (CSUM)

However, ROBUSTA-3A aims to do even more than chart water vapour from space.

The satellite carries an experimental Attitude Determination and Control System (ADCS) that will seek to optimize solar panel exposure and correctly aim sensors and microwave downlink antennas. Using a set of Sun sensors, magnetometers, and reaction wheels in a pyramidal configuration, the system should provide precise attitude control, especially during orbital maneuvers.

The satellite will also employ a cold gas thruster propulsion system which operates with solid iodine as propellant. This system will demonstrate orbit maintenance, phasing, and lifetime extension of small satellite missions, and could also help with end-of-life decommissioning and debris mitigation.

As an extra mission, the CubeSat will test how computer memory from chip manufacturer 3D PLUS withstands the radiation of space. This French company specialises in highly-reliable electronic components and their computer memory recently landed on the Moon as part of the India’s Chandrayaan-3 lander.

Finally, ROBUSTA-3A also carries a 9k6 GMSK AX.25 store-and-forward digital system with a UHF transmitter output of up to three watts — a very powerful downlink! As the satellite is sill in commissioning, operating protocols and uplink frequency have not yet been released. However, amateurs should expect something similar to the FalconSAT-3 store-and-forward system that was popular until that satellite deorbited in January of 2023. ROBUSTA-3A is currently transmitting short telemetry bursts on its International Amateur Radio Union (IARU) coordinated downlink frequency of 436.750 MHz.

SONATE-2 APRS Digipeater in Operation

Professor Hakan Kayal from Julius-Maximilians-Universität (JMU) Würzburg in Bavaria, Germany posted on X this past week, “Thanks to everyone using SONATE-2’s APRS digipeater over the weekend. A total of 421 messages were digipeated.”

The Bayerische Julius-Maximilians-Universität Würzburg’s SONATE (SOlutus NAno satelliTE) satellite is a technology demonstration mission for highly autonomous payloads and artificial intelligence in the 6U CubeSat class. As part of the SONATE-2 mission, novel hardware and software technologies of artificial intelligence (AI) are to be verified in miniaturized format in earth orbit. By using such AI technologies, the satellite can independently analyze the environment and start autonomous recordings. Deep learning plays a special role as a versatile image processing tool. In addition to the classification of targets already known at the start of the mission, the payload should also have the option of on-board training for the detection of anomalies as previously unknown objects or phenomena.


SONATE-2 mission patch (JMU artwork)

The operation of an amateur radio payload is important to the educational mission of SONATE-2. The development and operation of the satellite is used for the education of students of the university. In cooperation with the DLR School Lab in Neustrelitz, Germany, it is planned to use the amateur radio payload for the education of high school students.

The amateur payload of SONATE-2 consists of a VHF transceiver that was already built for the predecessor mission SONATE over the course of several student projects. For SONATE-2 additional student projects extended the transceiver functionalities. It will provide regular SSTV downlinks with images from the optical sensors included in the AI payload as well as an APRS digipeater and CW beacon.

On the education side, the mission will serve as a foundation for different aspects of the university aerospace and computer science engineering program. In the context of practical courses, as thesis authors or as student assistants, students can participate in the development of all subsystems of the space and ground segment, including the amateur radio payload and the technology demonstration payload. In the context of mandatory lectures and exercises on space operations every student will also be included in the operations of the satellite.

The German Aerospace Center (DLR) offers a School Lab for high school students at the location of the external ground station in Neustrelitz, Germany. Besides experiments on space and satellites, the School Lab includes amateur radio contacts to the ISS under the supervision of licensed local radio amateurs, which they wish to extend to other satellites like in this cooperation with the SONATE-2 mission.

Besides the amateur and educational mission parts, the SONATE-2 mission also has a research objective for the demonstration of novel artificial intelligence technology in the space environments. While the AI payload is mainly operated using a separate up/downlink in the space operation service in S-band, the satellite bus and the amateur payloads are operated in the amateur service. Housekeeping telemetry in the amateur service also contains status information of the non-amateur payload.


SONATE-2 Test Model, October 2023 (Photo: JMU)

According to Kayal, not many similar projects are currently being undertaken.

“Let’s assume that a small satellite is to investigate a new asteroid in the solar system in the future. It cannot be trained for this task on the ground, because the object of investigation is largely unknown. There is no training data, so the measurements and recordings can’t be made on the ground,” Kayal added.

Transmitting this data to Earth for initial processing and subsequently training the AI via remote control would result in significant time delays for missions located at a considerable distance from Earth.

Opting for a heightened level of autonomy with direct on-board AI support would greatly enhance the mission’s efficiency. This approach would expedite the detection of intriguing objects and phenomena on the asteroid, considerably reducing the time required for their identification.

To facilitate this, four on-board cameras capture the essential imagery required for training the AI. Initially, the AI acquires knowledge of conventional geometric patterns on Earth’s surface, among other things, which subsequently empowers it to autonomously identify anomalies.

In addition to these AI experiments, SONATE-2 carries a suite of other small satellite technologies that are ready for in-orbit testing. These technologies include an automated lightning detection and recording system, as well as an electric propulsion system developed in collaboration with the University of Stuttgart.

Kayal added, “In terms of complexity, SONATE-2 is unparalleled among nanosatellites.”

Wireless Technology Workshop in India

A special workshop on ‘Wireless Technology and its Practical Solutions’ was conducted for Rajkot – Police Wireless Department at Gujarat (India) on 20th July 2024. The venue was the Police Training Center at Rajkot Headquarter. It was a highly informative 3 hours session from 10:00 AM to 1:00 PM.

Regional Coordinator of AMSAT-INDIA & The Amateur Radio Society of India, Mr. Rajesh Vagadia, VU2EXP, gave insight into various Radio Communication protocols, types of modulation, modes & various applications used in Amateur Radio & Police department.


Rajesh Vagadia, VU2EXP (hamphotos.com)

As this workshop was targeted for 25 technical wireless officers & radio operators, we focused on the radio communication enhancing methods, utilizing various techniques, using different antennas for specific applications and diagnosis of wireless setup with various measuring instruments incl. SWR/Power Meter, NanoVNA/Antenna Analyzer. We extended a handful of maintenance tips for Radio, Antenna, Feed line & repeaters to optimize radio communications.

We also gave an overview of Ham Radio & its various events, Understanding of Digital Communication, Satellite Communication, Features of newer Digital protocol incl. DMR, D-STAR & Fusion. There was good interaction with participants, lots of doubt & queries were cleared satisfactorily. Good number of radio stuff was displayed incl. HTs, VHF Base Radio, IC-705 SDR HF Radio, RTL SDR Dongle, Antenna Tuner, CAT Control, Soundcard Interface, Morse Key, CW Paddle & Keyer, CubeSat model, Balun, LNA, SWR/Power meter, NanoVNA, Dummy load, PSU, Feed lines, EFHW Antenna, Telescopic Antenna, Connectors, Adaptors, ARISS Awards, QSL Cards etc., which helped participants to view, discuss & understand our entire stuff better.

We always give practical demos, but, here in the audience was a heavy user of CW & RT from the police dept. We didn’t give a demo of that kind hi..hi.., but surely gave demos of Digital Communication – sending text messages between two VHF Setup and a second demo of sending SSTV Images between two local vhf stations! For the audience it was interesting to learn how we ham convert simple ASCII codes to corresponding audio frequencies (for Digital Communication) and RGB pixel values of Image to Slow Scan Television format to transmit & receive ‘IMAGES’ via our standard radios! That’s why we proudly call Ham Radio the oldest Social Media!

It was a nice & fruitful workshop overall. I am thankful to Commissioner of Police Rajkot Shri Brajesh Kumar Jha Sir for approval of this workshop and Shri S K Jadeja Sir (PI Wireless) for nicely coordinating this workshop. I am thankful to our AMSAT-INDIA & ARSI (The Amateur Radio Society of India) for their great support and guidance to make this workshop highly successful.

We wish Rajkot Gujarat Police will utilize the gained knowledge & implement into the system for better productivity!

Small Satellites of the Future Grow Larger

Small satellite companies that have grown out of the New Space boom are retiring the cubesat platforms that made them to focus on larger, more powerful next-get small sats that promise to unlock new possibilities with advanced AI and real-time laser-based inter-satellite communications.

Over the past 15 years, small satellites have revolutionized how things are done in space. Built quickly from cheap, off-the-shelf components, and small enough to hitch an affordable ride to orbit on the back of bigger missions, these devices and the young, agile New Space companies behind them taught the old-school space industry a few lessons.

But New Space is coming of age and the firms behind the small satellite revolution must live up to expectations less favorable to their trade-mark experimental ethos. The lowest cost and shortest time to orbit may no longer be the technology’s biggest draw as users want maximum return on investment and require granted reliability. The firms behind the disruptive tech, however, have grown up together with their market share and are tapping into emerging innovation, looking to unleash a whole load of new applications in the coming years.
The Evolution of the Smallsat

Satellites started small. The first U.S. satellite, Explorer 1 — launched in 1958 — weighed only 14 kilograms. But the technology, prized for opening a whole new perspective on our planet, quickly bulked up, enabled by the increasing lifting powers of fast-evolving rockets. Soon, complex satellites the size of a school bus took over, observing the planet from above, broadcasting TV signals across continents and sensing the environment around them.

It was only in the mid-1980s that researchers renewed their interest in smaller satellites with masses of tens to a couple of hundred kilograms. The true small sat revolution, however, began in 1999, with the invention of a cubesat. Based on standardized satellite units of 10 by 10 by 10 centimeters in size, cubesats opened space to anyone with enough technical skill to assemble and operate them. Soon, university teams from all over the world began launching their own experimental spacecraft to provide their students with hands-on space tech experience.

By 2014, San Francisco-based Planet Labs launched its first commercial constellation of 28 three-unit (3U) Earth-observing cubesats called Doves. More than 120 Doves are in orbit today, capturing an image of each place on Earth more than once a day. Other companies followed suit. As of today, cubesats have made it to orbit around Mars and the Moon and observed the impact of NASA’s Double Asteroid Redirection Test (DART) into the asteroid Didymos in 2022 in real-time.

Larger small satellite platforms — up to 500 kg in mass — have also grown in popularity. In fact, these larger small satellites today dominate space around Earth thanks to SpaceX’s constellation of Starlink internet-beaming satellites.

Consulting firm Novaspace predicts that 26,104 small satellites — including minisatellites of 100 to 500 kg in mass, microsatellites between 10 and 100 kg and nanosatellites as light as 1 to 10 kg — will launch in the next decade.

And although the smallsat revolution is already behind us, new technologies are emerging that promise to supercharge the sector in the coming years. Via Satellite spoke with a number of experts in the field about what the smallsat of the future will look like.

ASRTU-1 Scheduled for November Launch

Published flight manifests indicate that the Chinese amateur radio satellite ASRTU-1 has been scheduled for launch in November of this year aboard a Russian rocket. As always, launches are subject to a wide variety of variables, and space agencies are not always 100% forthcoming about their activities. So while you may not want to mark the calendar just yet, hopeful signs are pointing toward a launch in the coming months.


Artist’s sketch of ASRTU-1

ASRTU-1 is a 12U Cubesat mission designed by Russian and Chinese university students for education and amateur radio. Harbin Institute of Technology has successfully developed several amateur radio satellites, including LilacSat-2 (CAS-3H), LilacSat-1 (LO-90), DSLWP-A (LO-93) and DSLWP-B (LO-94). The partner institution is Bauman Moscow State Technical University, which constructed two satellites, Baumanets-1 in 2006 and Baumanets-2 in 2017, both of which unfortunately failed to reach orbit due to launch failures unrelated to the satellite payloads.

The amateur radio station onboard ASRTU-1 will provide FM and telecommand uplinks, as well as FM, telemetry, and digital image downlinks. A new SDR based transceiver was developed to provide communication and experimental resources to radio amateurs, including a V/U FM transponder, a UHF telemetry downlink, and a 10.5G image downlink.

The repeater uplink will be on 145.875 MHz FM using a 67 Hz CTCSS (PL) tone. Downlink will be on 435.400 MHz FM. The telemetry beacon will be on 436.210 MHz using 9k6 bps BPSK.

In addition to the FM repeater, the satellite will also provide an open telecommand system to allow radio amateurs to send commands to control the satellite to take and download images. X Band image downloads using 1 Mbps/10mbps QSPK will downlink on 10.460 GHz.

ASRTU-1 has been scheduled for a Roscosmos launch from Vostochny Cosmodrome, Asiatic Russia, in Q4 2024 into a 530 km Sun-synchronous Orbit (SSO). Downlinks and the repeater uplink have been coordinated by the International Amateur Radio Union (IARU).

Satellite Shorts From All Over

+ The MESAT-1 team are continuing to test and commission the satellite. It is currently in Health Mode transmitting continuously and the downlink power is now about 6dB higher. So it should be easier to hear and decode. If you have had trouble decoding it then now is a good time to try again. Software may be downloaded from https://www.amsat.org/foxtelem-software-for-windows-mac-linux/ (ANS thanks Chris E. Thompson, VE2TCP / G0KLA / AC2CZ, for the above information.)

+ SpaceX is now targeting mid- to late August for the launch of Polaris Dawn, a mission funded by billionaire entrepreneur Jared Isaacman. The upcoming flight, which will employ SpaceX’s Crew Dragon spacecraft and Falcon 9 rocket, had been slated to lift off no earlier than July 31. SpaceX announced the delay today (July 26), during a press conference focusing on the company’s upcoming Crew-9 astronaut mission to the International Space Station (ISS) for NASA. The NASA mission will include Zena Cardman, KJ5CMN, Nick Hague, KG5TMV, Stephanie Wilson, KD5DZE, and Aleksandr Gorbunov, Roscosmos. Crew-9 will launch no earlier than Aug. 18, and Polaris Dawn will fly sometime after that, the company said. The Polaris Dawn mission is scheduled to include the first-ever private spacewalk. (ANS thanks Space.com for the above information.)

+ The U.S. military is installing modular state-of-the-art satellite jammers capable of disrupting Russian or Chinese communications, should the need arise. Even though the hardware is ground-based, the U.S. Space Force will oversee installation and operation. The technology is already past prototyping. The military tested the system at two different locations earlier this year. The Department of Defense allocated funds to build 24 remote installations, with 11 scheduled to deploy before the end of the year. (ANS thanks SatNews.com for the above information.)

+ SpaceX Falcon 9 returned to flight with three Starlink launches in 30 hours after only 15 days of being grounded due to its recent upper-stage anomaly (a brittle, and presumably cracked, pressure monitoring line) and conducted its 300th reflight of a booster. (ANS thanks The Orbital Index for the above information.)

+ Boeing performed a hot fire test of the 27 maneuvering thrusters aboard the docked Starliner space capsule, which could be the last test before the spacecraft’s delayed return to Earth is approved. Astronauts Barry “Butch” Wilmore, and Sunita Williams, KD5PLB, took Starliner to the International Space Station on June 5 for what was to have been a 10-day test flight. NASA says they may now return in late August. (ANS thanks The Orbital Index for the above information.)

TEVEL Satellites Begin Atmospheric Reentry and Decommissioning

The TEVEL satellite project, featuring a series of CubeSats designed and built by Israeli students, has entered its final phase with the beginning of atmospheric reentry and decommissioning. This initiative, a collaboration between the Israel Space Agency (ISA) and Tel Aviv University, has been a key educational tool, providing practical experience in satellite technology to students across Israel.

Launched in January 2022 on the SpaceX Falcon 9 Transporter-3 mission, the TEVEL satellites were part of a broader effort to promote STEM education. The CubeSats, built to the 10x10x10 cm standard, were used for various missions including scientific data collection, amateur radio communication, and technology experimentation. The project aimed to enhance students’ understanding of satellite technology and prepare them for careers in the space industry.

In addition to their educational value, the TEVEL satellites played a significant role in the amateur radio community. Equipped with radio transponders, they allowed amateur radio operators worldwide to communicate via satellite, fostering international collaboration and technological experimentation. This feature provided a unique platform for enthusiasts to engage in satellite communication.

As the satellites now re-enter Earth’s atmosphere, this phase marks the end of their operational lives. The reentry process, which involves the satellites burning up upon reentry to prevent space debris, is being monitored by both educational teams and the broader space community. This final stage offers a valuable learning opportunity for students tracking the satellites’ descent and analyzing the data.

Looking ahead, David Greenberg, 4X1DG, has announced a new TEVEL mission featuring nine additional satellites, continuing the educational and amateur radio goals of the original initiative. The decommissioning of the TEVEL satellites highlights the importance of responsible satellite disposal to minimize space debris and ensure the sustainability of space operations.

The success of the TEVEL project sets a precedent for future educational satellite initiatives, demonstrating how hands-on learning can be integrated with practical space missions. As the satellites complete their final descent, they leave behind a legacy of inspiration and international collaboration in both educational and amateur radio fields.

Ariane 6 Launches PariSat: Young Engineers Test Heat Dissipation

On July 9, 2024, Europe’s newest rocket, the Ariane 6, launched with a range of missions on board, each with unique objectives and dedicated teams. Among these missions was PariSat, a project that highlights the ingenuity and dedication of the Garef Aérospatial club. This amateur space club, comprised of young engineers aged 15 to 25, has been working diligently on satellite testing, with the goal of exploring how different materials handle heat dissipation in space.

The core of the PariSat experiment is to determine which materials are most effective at dissipating heat in the harsh environment of space. The project, however, is not just about the scientific results but also about the educational journey for the young engineers involved. Based in a modest building near the Georges Carpentier stadium in Paris’s 13th district, the club members work after school, applying their passion for space to design and build their satellite experiment.

PariSat features eight small square plates, each just 4 cm wide, which function as space radiators. These plates were chosen to test various properties such as material composition and color, and their responses to heating and cooling. Equipped with temperature sensors, each plate provided data on “black-body radiation” during the nearly three-hour flight of Ariane 6’s upper stage. This data will help validate the Stefan-Boltzmann law of thermal radiation, a principle discovered in 1884.

In addition to the scientific experiment, PariSat includes a photo component. The team has adapted a GoPro camera for space use, which is controlled by a module entirely designed by Garef Aérospatial. This camera, featuring a fisheye lens, captured stunning images of Earth, showcasing the planet’s curvature and adding a visual dimension to the mission.

PariSat is part of a larger set of five experiments, including Peregrinus, Sidloc, LiFi, and YPSat, which also remained attached to the Ariane 6’s upper stage during its three-hour flight. These experiments gathered data as the upper stage’s orbit was adjusted by the Vinci engine, which can be restarted multiple times. The collected data was transmitted back to Earth and received by the Swedish Space Corporation’s telemetry station in Kiruna, Sweden.

As the Garef Aérospatial team begins analyzing the data, the PariSat mission serves as a testament to the capabilities of young engineers and highlights the potential for youth-led initiatives in space science. With this mission, the team looks forward to future projects, driven by the experiences and successes gained from their participation in Ariane 6’s first flight.

SpaceX to Develop Enhanced Dragon Spacecraft for ISS Deorbit

SpaceX will develop an enhanced version of its Dragon spacecraft for NASA to deorbit the International Space Station (ISS) at the end of its operational life. This development comes as part of a contract awarded to SpaceX on June 26, valued at up to $843 million. The new spacecraft, known as the United States Deorbit Vehicle (USDV), was detailed by NASA and SpaceX officials at a briefing on July 17th.

The USDV will be based on SpaceX’s existing Dragon spacecraft but will feature a redesigned and larger trunk section with additional thrusters. Specifically, the USDV will have 46 Draco thrusters, including 16 for attitude control and 30 for the maneuvers required to lower the ISS’s orbit. Sarah Walker, SpaceX’s director of Dragon mission management, explained that the enhanced trunk section is twice as long as the regular one.

NASA presented the concept of the US Deorbiting Vehicle designed by SpaceX on July 17th. [Credit: SpaceX]
The new trunk will house engines, propellant tanks, power generation, and other systems, storing six times the propellant of the current Dragon spacecraft and generating three to four times the power. “It’s almost a spacecraft in and of itself,” Walker noted. Once completed, NASA will own and operate the USDV, which will be launched to the ISS shortly after the station’s final crew arrives.

After its arrival and successful checkout, ISS controllers will allow the station’s orbit to naturally decay. The final crew will depart when the station’s altitude decreases from its current 400 kilometers to 330 kilometers. The ISS’s orbit will continue to decay over approximately six months before NASA uses the USDV for a final controlled deorbit, targeting a remote ocean corridor about 2,000 kilometers long.

Dana Weigel, NASA ISS program manager, mentioned that debris from the station, ranging in size from a microwave oven to a sedan, is expected to survive reentry and splash down in this corridor. The USDV will have an estimated mass of over 30,000 kilograms, including 16,000 kilograms of propellant. Due to its size, it will require a heavier class of rocket than the Falcon 9 currently used for Dragon missions. NASA plans to procure the launch vehicle separately at least three years before the launch.

SpaceX expressed readiness to support the launch if given the opportunity. Northrop Grumman was the only other company to bid on the USDV. NASA’s source selection statement indicated that Northrop’s bid was significantly higher in price and rated lower in both mission suitability and past performance compared to SpaceX. Ken Bowersox, NASA associate administrator for space operations, expressed satisfaction with the proposals received, noting he was pleased with the submissions from SpaceX and Northrop Grumman.

Satellite Shorts From All Over

+ ASRTU-1 is a 12U CubeSat mission developed by students from the Harbin Institute of Technology and Bauman State Technical University. It is designed for educational purposes and features an amateur radio SDR payload. The satellite will offer telecommand uplink and telemetry/digital image downlink capabilities. Harbin Institute of Technology, known for developing successful amateur radio satellites like LilacSat-2 and DSLWP-B, has created a new SDR-based transceiver for ASRTU-1. This transceiver will provide communication resources, including a V/U FM transponder, UHF telemetry downlink, and a 10.5G image downlink. Scheduled to launch from Vostochny Cosmodrome on November 2024, ASRTU-1 will operate in a 530km sun-synchronous orbit with coordinated downlinks on 436.210 MHz, 435.400 MHz, and 10460.00 MHz and a repeater uplink on 145.875 MHz.

+ SpaceX successfully test-fired the engines on its Super Heavy booster on July 15, 2024, in preparation for the fifth integrated flight test (IFT-5) of its Starship vehicle. This upcoming launch, expected in August, will be the most ambitious to date and aims to build on the success of previous flights. The Super Heavy booster, measuring 233 feet tall, fired its 33 Raptor engines at full thrust for about 20 seconds during the static test at SpaceX’s Starbase facility in Texas. Starship, which has been selected by NASA for the Artemis 3 lunar mission, is designed as a fully reusable system capable of carrying humans to Mars. Unlike SpaceX’s Falcon 9, the Super Heavy booster is intended to return directly to its launch pad, where it will be caught midair by the launch tower’s “chopstick” arms. With each test flight achieving progressively more, SpaceX aims to test the booster catch system in the upcoming launch, marking a significant advance towards rapid reusability and future missions.

+ The 188,000-pound, 212-foot-tall core stage for the Artemis-2 moon mission has arrived at NASA’s Kennedy Space Center (KSC) following a 900-mile journey from Michoud Assembly Facility in New Orleans. This milestone marks a significant step in preparing for the Artemis-2 mission, which aims to return humans to the moon for the first time in over fifty years. NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian astronaut Jeremy Hansen are slated to launch on this mission as early as September 2025. Upon arrival at KSC, the core stage was transferred to a self-propelled transporter and moved into the iconic Vehicle Assembly Building (VAB). Engineers will soon begin processing the stage for stacking operations, involving the integration of the twin Solid Rocket Boosters (SRBs) and the spacecraft. The Space Launch System (SLS) rocket’s twin boosters and the core stage’s four RS-25 engines will generate nearly 9 million pounds of thrust at liftoff, propelling Artemis-2 and its crew to the moon.

+ NASA astronauts Butch Wilmore and Sunita Williams will remain at the International Space Station (ISS) with no set return date due to ongoing technical issues with Boeing’s Starliner capsule. The astronauts departed for the ISS in early June on a test mission expected to last about a week, but faulty thrusters and helium leaks have delayed their return. Despite some thrusters now functioning normally and the leaks being stable, NASA and Boeing are still not ready to schedule their departure. NASA assures that the astronauts are not stranded and the technical issues do not pose a threat to the mission. Engineers are conducting tests, including on a spare thruster in New Mexico, to understand and resolve the problems. Steve Stich, NASA’s commercial crew program manager, emphasized the priority of the astronauts’ safety and the consideration of backup return options. (ANS thanks Anna Betts, The Guardian, for the above information)

+ SpaceX is set to resume Falcon 9 launches as early as July 27 following the completion of an investigation into an upper stage anomaly from the July 11 launch. The mishap, which resulted in the rocket’s upper stage failing to perform a second burn and stranding Starlink satellites in a low orbit, was attributed to a liquid oxygen leak caused by a cracked sense line. This crack was due to engine vibration fatigue and a loose clamp. The resulting leak led to ice buildup and excessive cooling of engine components, causing a hard start and subsequent damage to the engine hardware. SpaceX has implemented immediate fixes and proposed long-term solutions, and the FAA has determined that there are no public safety issues, allowing launches to proceed. SpaceX is targeting July 27 for the next launch, with two more launches tentatively scheduled for July 28. (ANS thanks Jeff Foust, SpaceNews, for the above information)

POTA from Gloria Dei Church National Historic Place US-10802

Nine year-old Tawnse and I got half-way to activating the park before the ML-300 Bluetooth transmitter gave up the ghost. I knew I forgot to charge something. 

Tawnse was so entranced with the walled Philadelphia park she thought we should have stayed the extra half hour we would have probably needed to activate it. 

What led Tawnse to this scheduling priority decision? Turns out the park doubles  as the neighborhood dog park. There's only one way in or out though a small and, of course, historic  cemetery. By the time the pups got to the wander-around-unleashed bit we were in they were far to transfixed to try to leave. Turns out two of the pups were aspiring radio engineers to boot .Well get to that.

Because our antenna was low, propagation wasn't great on 20m at 15:30 UTC on the East Coast next to an interstate in Philadelphia. Even so right after I self-spotted a fellow ham immediately called in from South Dakota. After that, the QSOs came in every five minutes or so on average. We talked to Louisiana, two hams from Florida (whose QSOs came in back to back, and a ham from Tennessee. 

I'm curious if the QSOs from Florida might have come from the same physical station. Ill find out when I map out the activation. In the meantime, I really, really need to think more about local-first data and how to download map tiles onto this device.  I remember that Simon Wllison has written about this more than once on his blog, so Im basically leaving a reminder to myself to go look that up. It would be nice to map things when Im offline at least down to geographic regions like, lets say, cities?

The other folks who stopped by the park were very, very nice. Also, they had dogs. Tawnse and I met two daschunds, one of which was very fluffy, and two Golden Retrievers. All of whom introduced themselves at our picnic table.

Did I mention we had a low dipole placement? This would be the bit about our two radio-engineering dogs.

The Golden Retrievers immediately caught on to our dipole positioning being just to low, and they were certain they could fix it. They first sniffed out the rolls of tarred twine laying on the ground below each of the two trees that supported the dipole. They considered pulling on the twine. Perhaps I just hadn't really put my back into it. Then, they each decided it was probably a problem with the tree, and started to climb the tree following the twine. Until they remembered that they were dogs and heh, dogs don't climb trees. Abashed, one of them gave up. The other one though… That guy! He followed the antenna out of the tree till he saw TouCans which was only about six feet up, putting the dipole seven feet up. 

He. Could. Fix. This. He leapt at the radio to see if maybe he could adjust it. Fortunately, for all of us, his vertical leap was just a bit too short.

Tawnse just giggled and giggled and giggled. You gotta love engineering dogs.

Like I mentioned before, the Bluetooth transmitter's battery died right after the 5th QSO, and that was that. We were off to pick up KO6BTY from the library and get some of the best Italian food in the world from Paesanos on 9th St.

QSO map coming soon.


Project TouCans Lab Notebook: Getting Rid of the Noise

 I finally landed at a quiet tape vs. noise  configuration for TouCans on Saturday afternoon. Here’s how.


In the picture above, the wires circled in green include the + and - power wire, (white and red respectively), and the keyer wire, (also red.) When I taped the bundle of wires including the single turn coil shown in the white wire to the side of the can, the noise from the power supply went away. I was left with only noise from the radio, (the kind I want), and a gentle hum from the power supply because it had switched into buck converter mode to step its voltage up to the required 15V! The helicoptering from the Pico-W was also almost gone.

In other parts of the project, the Pico-W has started burning through pairs of AA batteries rather quickly.

POTA from Pope John Paul II Park in Quincy, MA US-8422

 Slowly but surely, KO6BTY, Tawnse and I are making our way back to the West Coast. Last night, we stopped in Quincy, MA for the flight we thought we were going to take this morning...

It looks like we are gonna call the East Coast our headquarters for a few more days, This has however, opened up POTA opportunities. Last night, I had the chance to activate Saint Pope John Paul II Park, US-8422, in Boston just across the Neponset River from where were staying in Quincy. The park is relatively new. It was opened to the public in 2001 and commemorates the Pope’s visit to Boston in 1979. It was constructed on the site of a landfill and a drive-in movie theatre.

Setting up near the river turned out to be a wash. The park is arranged so there is fairly thick vegetation between park denizens and the river.

I did, however get to set up about 10 yards back from the river in a pleasant little copse of trees. 

First though, I had to get the spools of twine up into the trees. For that, I was happy to find that there were plenty of branches under the hedge tree row


A few minutes later, TouCans was up!


Not only was the rig spotted in Europe, but it also made QSOs in England and Portugal!

Here is the map. For the moment, it has F2 skips. Please ignore them, I will get a map without them in place soon.

LobsterCon Wrap Up

 


The weather finally started to cool down a bit the day before LosterCon started. We had plenty of sun, but it wasn’t baking hot. 

The campground, where LobsterCon was held, Thomas Point Beach and Campground, was clean and well appointed, maybe too clean. There were no rocks laying about that would fit in the end of the tarred twine spools, so we wound up launching the antenna using pine cone stoppers. We had plenty of nice, flat ground for our two tents, and managed to get Project TouCans about 20 ft up between a pair of pine trees.


TouCans made two QSOs during LobstserCon, but the really nice part was all the in-person QSOs getting to hang out with everyone. 

KO6BTY and Tawnse diagrammed TouCans on the nearby beach the first evening. Later that night, the rig reached KF9VV in Wisconsin.


 The night after that, I made a short DX QSO with M7LLS. Then, we had lobster! So much lobster!

During the flea market, we got to check out new and old kits from W1REX of QRPMe.



TouCans is definitely back up and running. Check out the Reverse Beacon map during LobsterCon.
