Fram2Ham SSTV Transmissions Planned

Astronaut and radio amateur, Rabea Rogge LB9NJ / KD3AID, will be transmitting amateur radio Slow Scan TV images from space during the SpaceX Fram2 mission, planned for launch on March 31.

The Fram2 mission is set to become the first human space flight in polar orbit – flying over the North and South poles. Named after the famous polar exploration ship Fram, which completed voyages to both the Arctic and Antarctica. The SpaceX Falcon 9 rocket will launch four astronauts from Europe and Australia into orbit for 3-5 days.

During the Fram2 mission Rabea Rogge, LB9NJ (Norway) and KD3AID (USA), will be operating the onboard amateur (ham) radio system sending SSTV images as part of a high school and university student competition. These SSTV images will also be available to be received by the general public during the mission.

The International Space Station simulated the Fram2 SSTV mode PD-120 transmissions from February 13-17 on 437.550 MHz FM to enable people to gain proficiency in receiving the signals before the mission.

Fram2Ham is an experimental radio competition open to high school and university ages. Rogge will send pictures of three geographical locations via an onboard ham radio, but here’s the twist: they’ll be cut into pieces and mixed up! Participants will receive only fragments of the locations and need to guess where on Earth they are and what their role in polar history was. While anyone can receive the pictures, forming an international team may help you solve the puzzle!

There are several challenges like low transmit power, variations of antenna orientation, and a short, 3-day mission duration, with only a limited time assigned for the SSTV operation. These challenges require operating proficiency and the use of the best attainable radio station and this simulation shall give the possibility to exercise this.

For more information on the Fram2 mission and for youth organizations interested in participating in the Fram2Ham SSTV competition, see https://fram2ham.com/

Alba Orbital Assists AMSAT-EA With HADES-ICM Project

Alba Orbital (UK, USA, Germany) is the world’s leading PocketQube company that has delivered 53 pico-satellites on-orbit to date. These include five PocketQube satellites from three different countries recently flown on-board SpaceX’s Transporter-13 Rideshare mission.

Alba Orbital’s AlbaPod [Photo: Alba Orbital]

The satellites were integrated into Alba Orbital’s PocketQube Deployer, AlbaPod, at their new facilities in Hillington Industrial Estate, Glasgow, the world’s first PocketQube factory. After integration, the cluster of pocket-sized satellites were shipped out to SpaceX and then hitched their ride to LEO.

PocketQubes are highly miniaturized satellites, typically 5 cm cubed per unit (‘P’), that can be launched to orbit for as little as 25K euros via Alba Orbital’s rideshare services. PocketQubes are cost-effective, quicker to build, and provide versatile options for a variety of missions that range from educational projects to advanced technological demonstrations.

Payloads aboard this mission include HADES-ICM – HYDRA SPACE / IC MERCURY / SMART IR [Photo: Alba Orbital]

HADES-ICM, a 1.5p PocketQube, this smallsat is carrying an open voice transponder for the radio amateur community. It will be operated by the non-proft organization AMSAT-EA. The PocketQube includes the UK based Smart IR’s technology experiment that will be conducted on-orbit as well as an icMercury experiment. Inspiring space sustainability text messages that will be broadcasted periodically by HADES-ICM.

Firefly’s Blue Ghost Lander Photographs Eclipse From The Moon

Firefly’s Blue Ghost lunar lander snapped a gorgeous photo of a solar eclipse from the Moon in which Earth covers up most of the Sun, leaving only the so-called diamond ring effect.

[Photo: Firefly Aerospace]

The lander snapped the photo at around 05:30z on Friday March 14, as the Earth slowly blocked a view of the Sun. The solar eclipse on the Moon occurred at the same time as a total lunar eclipse here on Earth. Terrestrial viewers saw the lunar surface turn a red hue.

[Photo: Firefly Aerospace]

The eclipse lasted for around five hours at the lunar landing site in Mare Crisium. Firefly released another image from the earlier part of the eclipse that shows the lander’s solar panel as the Sun starts to hide behind Earth’s shadow.

Firefly’s Blue Ghost lander was launched on January 15 and successfully touched down on the Moon on Sunday, March 2 at around 07:30z. It landed upright, with no issues, unlike the Intuitive Machines lander which toppled over on landing on March 6.

This is Firefly’s first mission to the Moon, so Blue Ghost is packed with ten NASA instruments designed to probe the lunar surface and gather data to (hopefully) support upcoming human missions to the natural satellite. This is all part of NASA’s Commercial Lunar Payload Services (CLPS) initiative.

Not long after sunset at the end of the lunar day on March 16, 2025, the Lander’s batteries were depleted, communications were lost and the spacecraft’s mission was officially declared ended at 23:25z.

Changes to AMSAT-NA TLE Distribution for March 21

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/.

NOTICE: In an effort to minimize confusion between sources of two line element sets, AMSAT is adopting the convention of listing the USSF/NORAD Satellite Catalog name first, followed by any secondary name or names in parentheses. For example, “POEM 4 (BGS ARPIT)” was added recently where “POEM 4” is the name that appears in the U.S. Space Force Satellite Catalog, and “BGS ARPIT” is the name best known within the amateur satellite community. Expect name changes for affected satellites in the coming weeks as this change is fully implemented.

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

Satellite Shorts From All Over

+ The four members of the Crew-9 mission — Nick Hague, KG5TMV; Sunita Williams, KD5PLB; Barry “Butch” Wilmore; and Roscosmos cosmonaut Aleksandr Gorbunov — splashed down in the Gulf near Tallahassee, Florida shortly before 2200 UTC on Tuesday, March 18. Hague and Gorbunov launched to the ISS onboard the Dragon Freedom spacecraft in September 2024 and returned to Earth after logging 171 total days in space. Their colleagues, Williams and Wilmore, returned to Earth with 286 days in space after originally arriving at the space station onboard the Boeing CST-100 Starliner spacecraft launched on June 5, 2024. Prior to the departure of Starliner, two extra seats were created inside Dragon Endeavour (which brought up Crew-8) so that in the case of an emergency, Williams and Wilmore would have a way to return home. Thus, they were never actually “stranded” in space, as some media have reported. (ANS thanks SpaceFlight Now for the above information.)

+ The National Reconnaissance Office (NRO) annual conference will be held October 21-23, 2025. NRO brings together the best in academia and the private sector to keep America at the forefront of space-based intelligence, surveillance, and reconnaissance technology. NRO is soliciting abstracts for paper presentations at the conference. Previous topics included: Quantum Technologies, Artificial Intelligence, Advanced Manufacturing, Remote Sensing, Microelectronics, RF Technologies, Space Situational Awareness, & Other Enabling Technologies. Abstract deadline is April 18, 2025. See https://www.nro.gov/SRL/ for details. (ANS thanks David Vine, WA1EAW, for the above information.)

+ Researchers have broken a distance record in quantum communication by sending a secret encryption key nearly 13,000 km from China to South Africa, using a cheap, lightweight ‘microsatellite’. The satellite was able to send pulses of laser light, put into special quantum states, from a rooftop in Beijing to another at Stellenbosch University near Cape Town. The pulses formed a quantum key that was used to encrypt two images — one of China’s Great Wall and one showing part of Stellenbosch’s campus. The feat, a kind of encryption known as quantum key distribution (QKD), is a step towards being able to send ultra-secure messages between any two locations, however distant. (ANS thanks Nature.com for the above information.)

+ The increasing threat from space debris calls for both higher maneuverability in orbit and a reduction of the amount of junk. British startup Magdrive claims it can help with both, via a new propulsion system for spacecraft that will launch into space for the first time later this year and will be fueled by solid metal. The first incarnation of the Magdrive system — called Warlock — is set to launch into orbit in June 2025. It works by creating power using onboard solar panels to ionize metal. Once detonated, the metal is turned into extremely hot and dense plasma, or electrically charged gas. For now, the system is not refuelable. In the more distant future, however, the system could obtain its fuel from existing space junk, by harvesting dead satellites for metal to use as propellant. (ANS thanks CNN Science for the above information.)

+ In the next few months, from its perch atop a mountain in Chile, the Vera C. Rubin Observatory will begin surveying the cosmos with the largest camera ever built. But the rising number of satellites in orbit can be a problem for scientists because the satellites interfere with ground-based astronomical observations, by creating bright streaks on images and electromagnetic interference with radio telescopes. Until recently, astronomers had no centralized reference for tracking satellites. Now, the International Astronomical Union (IAU) has a virtual Centre for the Protection of the Dark and Quiet Sky from Satellite Constellation Interference (CPS), which serves as an information hub. One of the centre’s tools, called SatChecker, draws on a public database of satellite orbits, fed by information from observers and companies that track objects in space. Astronomers can use SatChecker to confirm what satellite is passing overhead during their observations. (ANS thanks Nature.com for the above information.)

Amateur Satellites Finally Launch After Delays

After delaying the launch of the mission a (highly unusual) seven times — it was originally slated to take to the skies on Feb. 27 — a SpaceX Falcon 9 rocket finally carried the 13th Rideshare to orbit on Saturday, March 15. The launch carried 74 small satellites to sun-sychronous orbit (SSO), lifting off from Vandenberg Space Force Base, California at 06:43 UTC (11:43 p.m. on March 14 local California time).

Among the satellites aboard is HADES-ICM 1.5 PocketQube satellite main mission is to act as a FM voice repeater. It can also repeat FSK derived modes like FT-4 and FT-8. It has the same functionalities as in HADES-R (SO-124). FM and Digital modes repeater with Uplink on 145.875 MHz and Downlink on 436.666 MHz. It also carries the same experiment for SMART-IR/Manchester University. The repeater will not be active until all the checks have been performed on the satellite. This can take several weeks.

A group of satellites labeled as “TEVEL2” are on the launch manifest for the SpaceX Transporter 13 mission. Designated as TEVEL2-1 through TEVE2-9, they are all listed as having a downlink frequency of 436.400 MHz, and are expected to be activated in rotation, much in the same way as the previous constellation of TEVEL satellites, which have now all decayed from orbit.

A French cubesat named UVSQ-Sat NG — or “Next Generation” is also on the launch manifest. This satellite appears to have capabilities for amateur operation, however no such operation has been coordinated or announced.

See AMSAT News Service bulletins 061 for more details on all of these satellites.

NASA’s SPHEREx, PUNCH Missions Launch

NASA’s SPHEREx and PUNCH missions were launched together on a SpaceX Falcon 9 rocket that lifted off from Vandenberg Space Force Base, California, on Tuesday evening, March 11 (early March 12 UTC). The launch had been delayed one day due to unfavorable weather at the launch site and an issue with one of the spacecraft.

SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) will then collect data on more than 450 million galaxies along with more than 100 million stars in the Milky Way in order to explore the origins of the universe, contributing to NASA Science’s key goals to discover the secrets of the universe and search for life elsewhere.

NASA’s SPHEREx mission will operate in low Earth orbit, detecting hundreds of millions of stars and galaxies and creating the first all-sky spectroscopic survey in the near-infrared. This artist’s concept shows the spacecraft and its distinctive conical photon shields, which protect SPHEREx’s telescope from infrared light and heat from the Sun and Earth. (Graphic: NASA/JPL-Caltech)

The mission’s 3D all-sky map will help scientists answer big-picture questions about the universe. The mission will investigate a cosmic phenomenon called inflation that caused the universe to expand rapidly for a fraction of a second after the big bang, measure the collective glow created by galaxies near and far, including hidden galaxies that have not been individually observed, and search the Milky Way galaxy for hidden reservoirs of water, carbon dioxide, and other essential ingredients for life.

The SPHEREx mission’s ability to scan large sections of the sky quickly and gather data on millions of objects complements the work of more targeted telescopes, like NASA’s Hubble and James Webb, and the observatory’s data will be freely available to scientists around the world, providing a new encyclopedia of information about hundreds of millions of cosmic objects.

Along for the ride was a second mission, PUNCH (Polarimeter to Unify the Corona and Heliosphere), a mission consisting of four satellites operating in concert. These small sats will observe the Sun’s corona as it transitions into the solar wind, supporting NASA Science’s key goals by creating a broad awareness and understanding of how the Sun creates conditions that influence Earth and space, which is increasingly part of the human domain.

By providing scientists with new information about how these potentially disruptive solar events form and evolve, data from PUNCH could lead to more accurate prediction about the arrival and impact of such events on Earth and for humanity’s robotic explorers in space.

Following orbital adjustments and commissioning, each of these two missions is planned to last for at least two years, contributing valuable data to the study of the universe and the sun’s influence on space weather.

ISS Changes Crew for Expedition 73

The 73rd long-duration expedition to the International Space Station (ISS) will begin with the departure of Soyuz MS-26, expected to take place in April 2025. The Expedition 73 crew will consist of astronauts cosmonauts just launched to the station aboard the SpaceX Crew Dragon Endurance, as well as those soon to follow aboard the Soyuz MS-27.

The crew of MS-26, Russian cosmonaunts Alexey Ovchinin and Ivan Vagner and American astronaut Don Pettit, KD5MDT, are already making preparations for departure in the coming weeks.

Scheduled for departure even sooner — probably in the coming week — is SpaceX Crew Dragon Freedom with two members of SpaceX Crew 9, astronaut Nick Hague, KG5TMV, and cosmonaut Aleksandr Gorbunov, accompanied by U.S. astronauts Barry “Butch” Wilmore, and Sunita Williams, KD5PLB. Wilmore and Williams were launched to the ISS in June of last year aboard the Boeing Starliner Crew Flight Test.

The astronauts of NASA’s SpaceX Crew 10 (from left) Kirill Peskov, Nichole Ayers, Takuya Onishi and Anne McClain, leave crew quarters at Kennedy Space Center, FL Wednesday, March 12, 2025 headed for the launch pad. They finally launched to the International Space Station on March 14.

SpaceX Crew 10 consists of NASA astronaut Anne McClain, who will serve as Crew-10’s commander. She is joined by Crew-10’s pilot, NASA astronaut Nichole Ayers, KJ5GWI, mission specialist Japanese Aerospace Exploration Agency (JAXA) astronaut Takuya Onishi, KF5LKS, and Roscosmos cosmonaut Kirill Peskov. Crew 10 was launched from pad 39A at the Kennedy Space Center in Florida on Friday, March 14, at 23:03 UTC after a scrub on Wednesday. The March 12 launch attempt was scrubbed due to an issue with the hydraulics on ground support systems on the launch pad.

That crew will be joined later next month by the crew of Soyuz MS-27, which is scheduled to consist of cosmonaunts Sergey Ryzhikov and Alexey Zubritsky, as well as American astronaut Jonny Kim.

Once the MS-26 crew departs, Takuya Onishi of the Japan will serve as the commander of Expedition 73, the third JAXA astronaut to take command of the station. Born in Nerima, Japan, Onishi earned an aeronautical and space engineering degree from the University of Tokyo and was a co-pilot of Boeing 767 airplanes from 2003 to 2009. Onishi will fly to space for the second time on Crew-10, having previously flown to the ISS aboard Soyuz MS-01 in 2016 as part of Expedition 48/49. JAXA and NASA selected Onishi for NASA’s 20th astronaut group in 2009.

Expedition 73 will continue the extensive scientific research conducted aboard the ISS, focusing on various fields, including biology, human physiology, physics, and materials science. The crew members will also maintain and upgrade the space station systems.

Satellite Shorts From All Over

+ AMSAT Italia is pleased to announce the renewal of its Board of Directors, which were elected on February 26th and assigned to the role on March 3rd. The new Board of Directors, in charge for the period 2025-2027, consists of:

• De Paolis Francesco IKØWGF – President / Treasurer
• Ferrario Gianpietro IZ2GOJ – Vice President
• Andrioli Fabio IZØQPO – Secretary
• Ariotti Claudio IK1SLD – Board Member
• Tognolatti Piero IØKPT – Board Member

Andrioli Fabio IZØQPO and Tognolatti Piero IØKPT join the BoD after being former members of the board of auditors. Fabrizio Carrai IU5GEZ and Emanuele D’Andria IØELE leave the BoD, while Emanuele IØELE was already appointed by the assembly of associates as President Emeritus of AMSAT Italia. For more information about AMSAT Italia and its activities, please visit their website https://www.amsat.it. (ANS thanks Francesco De Paolis, IKØWGF, for the above information.)

+ Intuitive Machine’s IM-2 Athena lander touched down near the Moon’s south pole, 250 meters from its target in the Mons Mouton region, inside of a crater. But, while a softer landing than last time, like IM-1 in Feb 2024, the lander appears to have fallen over into an “incorrect attitude” ending up “somewhat on its side.” A day later the mission was declared over, with little hope of even partial recovery due to solar panels oriented in the wrong direction and the extreme cold temperatures in the crater. (ANS thanks The Orbital Index for the above information.)

+ With somewhat better luck, another private lunar lander carrying a drill, vacuum and other experiments for NASA touched down on the moon on March 2, the latest in a string of companies looking to kickstart business on Earth’s celestial neighbor ahead of astronaut missions. Firefly Aerospace’s Blue Ghost lander descended from lunar orbit on autopilot, aiming for the slopes of an ancient volcanic dome in an impact basin on the moon’s northeastern edge of the near side. (ANS thanks The Associate Press for the above information.)

+ Starship blew up over the Caribbean, again. Starship Flight 8 seems to have suffered the same fate as its predecessor. Eight minutes into Ship 34’s powered flight, four of its six Raptor engines shut down, and the craft began to tumble. Minutes later, it exploded over the Caribbean, producing a similarly spectacular light show as the last flight. In better news, Super Heavy Booster 15 was again caught by its launch tower, an incredible feat that is somehow slowly starting to look routine. (ANS thanks The Orbital Index for the above information.)

+ NASA recently turned off Voyager 1’s cosmic ray subsystem experiment and Voyager 2’s low-energy charged particle instrument to conserve power. At 43 years old, both craft are at half their initial power levels, now operating at around 235W each and losing about 4W of power generation capacity each year. In part, this is due to the 87.7-year half-life decay of Plutonium-238, which powers the probes’ three Multi-Hundred-Watt Radioisotope Thermoelectric Generators. (ANS thanks The Orbital Index for the above information.)
