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. (ANS thanks NASA Jet Propulsion Laboratory for the above information)

+ 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.

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.

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).

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.

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.

+ 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. (ANS thanks Josh Dinner, Space.com, for the above information)

+ 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. (ANS thanks Mike Killian, AmericaSpace.com, for the above information)

+ 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)

SpaceX Falcon Heavy Successfully Launches GOES-U Satellite

On June 25, a SpaceX Falcon Heavy rocket successfully lifted off from Kennedy Space Center’s Launch Complex 39A at 5:26 p.m. Eastern, carrying the GOES-U weather satellite, the final spacecraft in a series of geostationary weather satellites. This launch featured several notable firsts, overcoming previous weather forecasts that had predicted only a 30% chance of favorable conditions.

The GOES-U satellite, successfully deployed from the Falcon Heavy’s second stage four and a half hours after liftoff, after the stage completed a sequence of three burns to place the satellite into a geostationary transfer orbit. Built by Lockheed Martin for the National Oceanic and Atmospheric Administration (NOAA), GOES-U will be renamed GOES-19 upon reaching geostationary orbit. After on-orbit commissioning, it will be positioned at 75 degrees east in geostationary orbit, taking over from GOES-16 as the operational GOES-East satellite.

GOES-U carries a suite of earth and space science instruments similar to its predecessors but includes the new Compact Coronagraph (CCOR) instrument for solar observation. CCOR will monitor the solar corona for flares and coronal mass ejections, a crucial function for understanding space weather. This role was previously filled by the nearly 30-year-old Solar and Heliospheric Observatory spacecraft.

The GOES-R series, which began with a launch in 2016, has significantly improved weather forecasting. Ken Graham, director of the National Weather Service, stated at a pre-launch briefing, “The GOES-R series of satellites, it’s been a gamechanger for us.” The satellites have enabled new and improved forecasts, warnings, and services that help save lives and protect property.

Among the enhancements in the GOES-R series is a lightning mapper. Pam Sullivan, director of the GOES-R program at NOAA, highlighted its impact, saying it allows meteorologists to better understand storm severity and issue more accurate warnings. “The main thing I hear from forecasters is that they have more confidence in a forecast,” she noted.

NOAA is already planning the next generation of geostationary weather satellites, called GeoXO, set to begin launching in 2032. Contracts have been awarded to Lockheed Martin for satellite construction and BAE Systems for sounder and ocean color instruments. Steve Volz, assistant administrator of NOAA’s Satellite and Information Service, described GOES-U as “the bridge that connects today’s geostationary satellite technology with the technology of tomorrow.”

The launch was marked by the synchronized landings of the two Falcon Heavy side boosters at Landing Zones 1 and 2 at Cape Canaveral Space Force Station. This mission was also the first time NOAA launched a GOES weather satellite on a SpaceX rocket. The three previous GOES-R satellites launched on Atlas 5 rockets from United Launch Alliance (ULA), but SpaceX was awarded the $152.5 million contract for the GOES-U launch in September 2021 after ULA withdrew due to a lack of available Atlas rockets.

The Falcon Heavy’s additional performance is a key advantage. Julianna Scheiman, director of NASA science missions at SpaceX, explained that the rocket’s capability allows for a significant delta V reduction, meaning the spacecraft requires less energy to reach its final orbit. This efficiency translates into fuel savings and extended operational life for GOES-U, which has a design specification of 15 years. “With the added capability Falcon Heavy is giving us, we expect to be at 20-plus years of fuel life,” said NOAA’s Sullivan.

The GOES-U launch marked the 10th overall for the Falcon Heavy and the second contracted by NASA, following the Psyche asteroid mission in October 2023. Another Falcon Heavy is set to launch NASA’s Europa Clipper mission this October, continuing SpaceX’s role in advancing space exploration and weather monitoring capabilities.

Satellite Shorts From All Over

+ The Ariane 6 rocket recently completed its final ‘wet dress rehearsal’ at Europe’s Spaceport in French Guiana, marking a crucial milestone before its maiden launch. This rehearsal involved loading 180 tons of supercooled propellant into the rocket, cooling its components to cryogenic temperatures, and rolling back the mobile gantry. ESA’s Guy Pilchen highlighted that this rehearsal allowed teams to refine launch operations using the actual flight hardware and software. Following fueling, the rocket underwent final preparations for its upcoming launch, expected to confirm its date after data analysis. With payloads ranging from Earth observation to scientific experiments, Ariane 6 aims to secure Europe’s independent access to space and advance space exploration. (ANS thanks the European Space Agency for the above information)

+ China’s Chang’e 6 probe has returned to Earth on June 25, 2024, with the first-ever samples from the far side of the moon, landing in Inner Mongolia on Tuesday. The successful mission marks a global milestone, with the samples expected to include 2.5 million-year-old volcanic rock that could shed light on the geological differences between the moon’s near and far sides. The probe landed in the moon’s South Pole-Aitken Basin, providing samples from various geological layers. This mission is part of China’s growing space rivalry with the U.S. and other nations, aiming to establish China as a technological power. The journey began on May 3 and lasted 53 days, involving drilling into the core and collecting surface rocks. China plans to share the samples with international scientists, hoping to answer fundamental questions about lunar geology and the solar system’s early days. (ANS thanks Huizhong Wu, Associated Press, for the above information)

+ NASA called off a planned spacewalk on June 24 due to a malfunction in astronaut Tracy Dyson’s spacesuit. Dyson and her crewmate Mike Barratt were preparing to exit the International Space Station to conduct maintenance when a water leak was detected in Dyson’s suit cooling unit. This unit is crucial for maintaining a comfortable temperature during spacewalks. The leak occurred just after the suits were switched to battery power, prompting NASA to abort the mission. Although Dyson reported feeling a bit warm and expressed concerns about potential water damage to electrical connectors, both astronauts were safe throughout the incident. This cancellation follows a similar recent setback on June 13, involving a spacesuit issue, and it raises questions about the potential impact on the return schedule of Boeing’s Starliner capsule. (ANS thanks Jackie Wattles, CNN, for the above information)

+ NASA astronauts Suni Williams and Butch Wilmore, who flew Boeing’s Starliner capsule to the International Space Station (ISS), have had their return to Earth delayed multiple times due to issues with the spacecraft. Originally planned to stay for about a week, their mission has been extended indefinitely as NASA and Boeing investigate a slow helium leak and malfunctioning thrusters discovered after reaching orbit. The latest delay was announced last week, with no new return date set yet. Despite these issues, the astronauts are assisting with tasks and conducting tests on the ISS, where they are accommodated with sufficient supplies. NASA is taking a cautious approach, allowing data to drive decisions about managing the leaks and thruster performance. This mission aims to certify the Starliner for future routine flights, similar to SpaceX’s Crew Dragon service for NASA. (ANS thanks Denise Chow, NBC News, for the above information)

Setting Up Your Own Satellite Ground Station with SatNOGS

Robert Theiss, W5ITR, had the pleasure of interviewing Dan White, ADØCQ, from the Libre Space Foundation at the 2024 Dayton Hamvention about their innovative SatNOGS project. This initiative enables anyone to set up a satellite ground station, collect valuable data, and contribute to global satellite operations. You can watch the interview here on the Digital Rancher YouTube channel: https://www.youtube.com/watch?v=edNfD_YXZps

Dan explained that SatNOGS provides detailed blueprints and documentation for building a satellite ground station from scratch. The foundation offers the necessary software, identifies accessible hardware, and maintains the infrastructure that allows citizen scientists to engage in satellite-related sciences. Their vision of making outer space open and accessible through open-source technology is truly inspiring.

Setting up a basic SatNOGS station is surprisingly straightforward. All you need is a Raspberry Pi and an RTL-SDR dongle. Dan explained the process: the Libre Space Foundation provides a ready-to-use image for the Raspberry Pi, which includes the operating system and necessary configurations. You just create an account, register your station, and schedule a test observation.

For those looking to enhance their setup, SatNOGS offers extensive documentation on building antennas and integrating additional components like low noise amplifiers and band pass filters. Although they plan to offer kits in the future, you can currently follow the detailed instructions and suggested links available on the SatNOGS Wiki: https://wiki.satnogs.org.

One of the most fascinating aspects of SatNOGS is its network of interconnected ground stations. Once your station is set up, it can schedule satellite passes and collect data, even while you’re asleep. This data is shared across the network, allowing other users to access it, and vice versa. This system ensures continuous monitoring and data collection, maximizing the utility of each station.

The SatNOGS community is highly active and supportive. The forums on the Libre Space Foundation’s website are a great resource for troubleshooting, sharing experiences, and staying updated on new satellite launches and developments.

For those interested in taking their ground station to the next level, SatNOGS supports more advanced setups with full azimuth and elevation rotators and larger antennas. These setups, while more costly, significantly increase data collection capabilities and overall performance. The Raspberry Pi used in the basic setup can interface with these advanced systems, allowing for automated tracking and data collection.

Dan shared insights into practical aspects such as bandwidth requirements and equipment wear and tear. While the data collected by a SatNOGS station can be bandwidth-intensive, there are settings to optimize for lower bandwidth situations by disabling audio uploads. Additionally, proper setup and maintenance of antennas and rotators can ensure long-term operation without significant issues.

The Libre Space Foundation and its SatNOGS project provide a unique opportunity for anyone interested in satellite and space communications to get involved. Their open-source approach and comprehensive support make it accessible even for beginners. Setting up your own satellite ground station is a rewarding experience, contributing to global space exploration and satellite communication. Check out the resources at https://satnogs.org and get involved!

SpaceX Aims for Successful Reentry in Fourth Starship Test Flight

SpaceX is targeting June 6th for the fourth test flight of its Starship megarocket, aiming to demonstrate the rocket’s ability to survive reentry, according to founder and CEO Elon Musk. This objective marks a crucial step in proving the reusability of the world’s most powerful rocket, following three prior test flights that showcased its capacity to reach space.

On May 20th, SpaceX carried out a crucial test by loading over 10 million pounds of super-cold methane and liquid oxygen propellants into the Super Heavy booster and the Starship upper stage. This practice countdown, which concluded before engine ignition, was one of the last major tests before the rocket’s flight. Following the test, the launch team drained the propellants, and ground crews removed the Starship upper stage to perform additional work on its heat shield.

The next steps include installing the rocket’s self-destruct mechanism, to be used if the vehicle deviates off course, and securing a commercial launch license from the Federal Aviation Administration (FAA). The FAA is reviewing the results of SpaceX’s previous Starship test flight in March, which was classified as a mishap after the vehicle lost control and disintegrated during reentry.

SpaceX has requested the FAA approve the upcoming launch before the mishap investigation concludes, arguing that the previous flight did not pose a public safety risk. An FAA spokesperson indicated that this could expedite the licensing process if no public safety issues are identified.

Meanwhile, SpaceX is preparing hardware for multiple rockets scheduled to fly later this year and building additional launch sites in Texas and Florida to support an increased launch frequency. However, significant design challenges remain before Starship becomes fully operational.

Unlike the March test flight, which included several experiments such as payload bay door operations and liquid oxygen transfer, the upcoming mission will concentrate on controlling the reentry of both the Super Heavy booster and the Starship upper stage. Both components broke apart during descent in the last flight.

SpaceX aims for the Super Heavy booster, named Booster 11, to achieve a controlled splashdown in the Gulf of Mexico, while the Starship upper stage, known as Ship 29, will attempt to survive the extreme reentry conditions. The rocket is equipped with about 18,000 hexagonal heat-absorbing ceramic tiles to protect its stainless-steel structure during reentry, where temperatures can reach approximately 2,600°F (1,430°C).

Musk has indicated that, assuming a successful splashdown, SpaceX could attempt landing a Super Heavy booster back at the Texas launch pad as early as the fifth test flight later this year. However, due to harsher reentry conditions from orbital velocity, landing the Starship upper stage might take longer.

NASA, which selected Starship to ferry astronauts to and from the Moon for its Artemis program, is closely monitoring these developments. A critical milestone for NASA is the in-orbit engine restart, necessary for guiding Starship towards controlled reentry and future lunar missions. While this capability will not be tested on the next flight, achieving reliable engine performance remains a primary focus.

“For us, primarily, it’s the successful light of those Raptor engines and achieving main stage with all of them on Booster 11,” said Lisa Watson-Morgan, manager of NASA’s Human Landing System. The next flight aims to ensure consistent engine performance, crucial for SpaceX and NASA’s lunar ambitions.

Reigniting Raptor engines in space is essential for future missions, but SpaceX is taking a step-by-step approach. “If we can’t light all 33 engines on the booster, and if we can’t light all six engines on the ship, then we’re going to have trouble getting to where we need to go,” Watson-Morgan said. “So it’s basically a building-block approach.”

As SpaceX prepares for its fourth Starship test flight, the focus on surviving reentry represents a critical hurdle in its mission to develop a fully reusable rocket system capable of reaching, and returning from, space.

Expect ISS radio outage for Progress 88 docking from May 31 1720 UTC until June 2 1415 UTC. The crossband repeater continues to be active (145.990 MHz up {PL 67} & 437.800 MHz down). If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know.

The packet system is also active (145.825 MHz up & down).

As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol.

Note, all times are approximate. It is recommended that you do your own orbital prediction or start listening about 10 minutes before the listed time.

Upcoming Satellite Operations

G0ABI will activate grid square IN79 from the historic Lizard Wireless Station at Bass Point via GreenCube (IO-117) satellite on June 6th. Lizard Wireless Station is the site where Guglielmo Marconi conducted his pioneering wireless experiments in 1900. Marconi proved radio communication over the horizon by receiving a transmission from the Isle of Wight in 1901 and later received the first SOS call in 1910. His work at “The Lizard” led to the first transatlantic radio signal, paving the way for global wireless communication. Celebrate Marconi’s legacy by making contact with G0ABI from this iconic location. For more details about the Lizard Wireless Station, visit https://shorturl.at/DMZ68.

A growing number of satellite rovers are currently engaged in sharing their grid square activations on https://hams.at. By visiting the website, you gain easy access to comprehensive information about the operators responsible for activating specific grid squares. Additionally, you have the ability to assess the match score between yourself and a particular rover for a given pass, while also being able to identify the upcoming satellite passes that are accessible from your location.
