Five CubeSats Successfully Deployed from “Kibo” Module on ISS

On December 9th, five CubeSats were successfully deployed from the Japanese Experiment Module “Kibo” aboard the International Space Station (ISS). The deployment was part of JAXA’s J-SSOD#30 mission and included DENDEN-01, LignoSat, ONGLAISAT, YODAKA and YOMOGI satellites. Two of these satellites, LignoSat and YOMOGI, have received previous IARU coordination to operate over amateur radio frequencies.

LignoSat was developed by Kyoto University and Sumitomo Forestry Co., Ltd. This CubeSat tests the use of wooden materials in space by measuring strain, temperature, and geomagnetism, along with detecting single event upsets (SEU). Amatuer radio satellite enthusiasts were ready to decode telemetry from the satellite this week, but unfortunately there has been no reported reception of either CW or AX.25 packets on the satellite’s coordinated frequency of 435.820 MHz.

DENDEN-01 was developed by Kansai University and partner institutions. Its mission includes testing advanced nanosatellite technologies, such as temperature-stabilizing devices, thin solar modules, and compact S-band communication systems. The satellite also supports educational activities and data analysis using a compact hyperspectral camera.

ONGLAISAT is a 6U CubeSat co-developed by the Taiwan Space Agency, the University of Tokyo, and ArkEdge Space Inc. It features a telescope for high-resolution Earth imaging using Time Delay Integration (TDI) technology. This mission aims to produce clear and high signal-to-noise ratio images for Earth observation.

YOMOGI was developed by the Chiba Institute of Technology. Its mission combines environmental monitoring and engineering education. The satellite observes red tide in Tokyo Bay, monitors water pollution in Uganda, and uses APRS to send sensor data to ground stations. Many 4800 baud GMSK telemetry packets have been received and decoded over the last few days indicating that the satellite is functioning well. More information can be found on SatNOGS regarding recent observations: https://db.satnogs.org/satellite/HHVN-9456-4962-8588-2802#data

YODAKA was developed by ArkEdge Space Inc. and other collaborators. It features a store-and-forward communication mission, collecting and retransmitting text messages from users on Earth, as well as a camera mission to capture Earth imagery. These activities support educational programs at Iwate Prefectural Hanamaki Kita High School and rural revitalization efforts in Hanamaki City.

The deployment highlights collaboration between JAXA, Space BD Inc., Mitsui Bussan Aerospace Co., Ltd., and the J-CUBE program, which fosters academic and commercial utilization of CubeSats. Amateur radio operators and educational institutions are actively participating in tracking and analyzing data from these satellites.

Celebrate SO-50: Amateur Radio Special Event Marks 22nd Anniversary

Saudisat 1C (SO-50) was launched on December 20, 2002, from the Baikonur Cosmodrome by the King Abdulaziz City for Science and Technology (KACST). For more than two decades, it has been a valuable resource for amateur radio communications and remains operational in low Earth orbit. The satellite is equipped with a mode V/U FM voice repeater, operating on an uplink frequency of 145.850 MHz with a PL tone of 67.0 Hz and a downlink frequency of 436.795 MHz.

To celebrate the 22nd anniversary of SO-50, the Saudi Amateur Radio Society (SARS) is organizing a global competition, the Saudi Sat SO-50 Event 22. The event will take place from December 13, 2024, at 00:00 UTC to December 22, 2024, at 23:59 UTC, inviting amateur radio operators to make contacts (QSOs) via the satellite during the competition period.

Participants in the competition will be eligible for certificates based on the number of successful contacts they make with amateur stations in different Maidenhead grid squares. Five successful contacts will earn a Beginner Satellite Catcher Certificate, while ten successful contacts qualify for an Advanced Satellite Hunter Certificate. Those who achieve twenty successful contacts will be awarded a Professional Satellite Hunter Certificate. Operators who document their contacts with audio or video recordings, including the satellite name, date, and time, will receive a distinguished Amateur Certificate. Certificates will be distributed in PDF format, and the deadline for log submissions is January 10, 2025.

Logs must be submitted to log [at] sars.sa. For technical support or additional information, participants can contact hzldg [at] sars.sa. This competition highlights the enduring success of SO-50 and encourages its continued use in the global amateur radio community. It provides a platform for operators to connect, compete, and celebrate the satellite’s legacy.

ESA’s Proba-3 Satellites Launch to Create Artificial Solar Eclipses

Two European Space Agency (ESA) satellites launched aboard an Indian rocket on December 5th, beginning a mission to study the Sun’s corona and demonstrate new spaceflight technologies. Called the Proba-3 mission, the two spacecraft will conduct formation flying and create artificial solar eclipses to capture images of the Sun’s outer atmosphere, which is usually hidden by its brightness.

The satellites launched aboard India’s Polar Satellite Launch Vehicle (PSLV) at 5:34 am EST (10:34 UTC) and were placed into an elliptical orbit with a low point of 356 miles (573 kilometers) and a high point of 37,632 miles (60,563 kilometers). Early next year, the Coronagraph satellite, carrying instruments to image the Sun, and the Occulter satellite, equipped with navigation sensors and thrusters, will separate to begin their experiments. The Occulter will position a disk to block the Sun’s surface, casting a shadow on the Coronagraph satellite.

This arrangement allows scientists to create artificial eclipses, blocking sunlight to reveal the solar corona. Natural solar eclipses offer only brief observation windows, and traditional coronagraphs on single spacecraft face challenges like diffraction. Proba-3 addresses these limitations by keeping the two satellites 150 meters apart, enabling clearer imaging of the Sun’s outer atmosphere.

Proba-3 uses advanced navigation technology, including inter-satellite radio links, cameras, and a laser-ranging system. This system maintains millimeter-scale precision between the satellites, allowing them to create artificial eclipses lasting up to six hours. The mission aims to conduct at least 1,000 hours of such observations during its two-year operational phase.

The mission’s scientific goal is to observe a part of the corona that existing instruments cannot study. This region is critical for understanding solar phenomena such as coronal mass ejections and the acceleration of the solar wind, which affect space weather and Earth. The mission will also capture high-frequency images to study plasma waves and jets that may heat the corona and drive the solar wind.

Proba-3 also serves as a test of formation-flying technology. ESA officials hope the techniques demonstrated will be used in future missions, such as Mars Sample Return or space debris removal. “Proba-3 is an important step toward more complex space operations,” said Josef Aschbacher, ESA’s director general. “This mission shows how smaller spacecraft can work together to achieve goals that were not possible before.”

Satellite Shorts From All Over

+ NASA has announced delays to its Artemis moon program, pushing Artemis II, a crewed mission around the moon, to April 2026, with the Artemis III lunar landing planned for mid-2027. NASA Administrator Bill Nelson emphasized that this timeline keeps the U.S. ahead of China’s goal to land on the moon by 2030, highlighting the competitive nature of the space race. The delays follow concerns about the Orion capsule’s heat shield, which cracked during reentry after the uncrewed Artemis I test mission in 2022; Artemis II will proceed with adjustments to the capsule’s trajectory, while future missions will feature an upgraded heat shield. Artemis, initiated under former President Trump’s administration, aims not only to return astronauts to the moon but also to establish lunar bases as a stepping stone for Mars exploration, despite rising costs and development delays. The program’s reliance on SpaceX’s Starship for lunar landings has raised questions about its cost-effectiveness, especially under the incoming Trump administration. Nelson expressed optimism about Artemis’s continuity under NASA’s next administrator, Jared Isaacman, amid ongoing bipartisan and international support for lunar exploration.

+ NASA recently awarded SpaceX a $256.6 million contract to launch Dragonfly, a rotorcraft designed to explore Titan, Saturn’s largest moon, using a nuclear-powered radioisotope thermoelectric generator (RTG). This marks a milestone for SpaceX, as it will be the company’s first time launching a nuclear-powered payload, a domain previously dominated by United Launch Alliance (ULA). The RTG will generate electricity from plutonium-238, chosen because Titan’s dim and cloudy atmosphere precludes the use of solar power. Dragonfly will explore Titan’s surface by hopping between locations using its eight rotors, investigating organic molecules essential to understanding the building blocks of life. Originally set for a 2026 launch, delays due to redesigns, COVID-19 impacts, and supply chain issues have pushed the timeline to July 2028, with costs escalating to $3.35 billion. This mission, one of NASA’s most ambitious robotic endeavors, underscores the transition to new-generation rockets for launching nuclear payloads, with SpaceX’s Falcon Heavy beating ULA’s Vulcan rocket in competitive bidding for this historic mission. (ANS thanks SpaceNews for the above information)

+ The USC Rocket Propulsion Lab (USCRPL) at the University of Southern California has shattered the international altitude record for amateur rocketry with their Aftershock II rocket, reaching an unprecedented 470,000 feet. This achievement surpasses the previous 20-year record of 380,000 feet set by the Civilian Space Exploration Team in 2004, establishing Aftershock II as the first civilian-built rocket to achieve this altitude. Equipped with the most powerful solid-propellant motor ever fired by students and enhanced thermal protection systems, the rocket endured hypersonic speeds with innovative features like titanium-coated fins and a custom paint system. The launch on October 20th in Nevada’s Black Rock Desert also demonstrated advanced avionics and live data integration, enabling precise tracking and recovery. Building on their milestone 2019 launch of Traveler IV, the first student-designed rocket to cross the Kármán line, USCRPL continues to push the boundaries of amateur rocketry with cutting-edge engineering and teamwork. This remarkable achievement highlights the group’s role as a training ground for future leaders in the space industry, inspiring innovation and excellence among aspiring astronautical engineers.
