Amateur Satellites Scheduled for Launch This Week

A SpaceX Falcon 9 rocket will launch a dozens of satellites on the company’s 13th smallsat rideshare mission to a sun-synchronous orbit. The launch is currently scheduled for Tuesday, March 4.

Among those satellites 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.

As there is a small empty space available, it will be used to carry an experiment by Smart IR/Graphene Engineering Innovation Centre, GEIC University of Manchester (UK) consisting in a very low power active radiator to be tested on space conditions. The data for this experiment will be transmitted in a specific data packet in the telemetry. This experiment is the same as the one in HADES-R [now SO-124 — see ANS-054]. This experiment will be delivered to AMSAT EA for integration and will be operated by AMSAT-EA, being all its data public and open.

Engineering and manufacturing support for this mission is carried out with the help of private sector companies and universities, but AMSAT-EA will be the only operating organization.

icMercury is a company also supporting the mission. It will develop ground tracking software for the satellite. Telemetry will send some FSK English formatted text messages, part of a history, to be collected as a challenge.

HADES-ICM will offer licensed radio-amateur around the world the opportunity to relay FM voice and AX.25 / APRS 300 / 1200 bps communications. FSK derived transmissions and modes like FT-4 and FT-8 are also supported. As an improvement from previous missions, maximum power is now 0.25W when battery is charged (the amplifier uses battery energy), allowing easier QSOs with handheld antennas like Arrow or Elk and less sensitive receivers.

The satellite will also transmit telemetry with its status and CW messages. This all will be achieved by implementing a SDR based repeater. The FM / FSK repeater will be available all time and opened by squelch level without the need of a subtone.

As payload, the satellite will carry an experiment by Smart IR/Graphene Engineering Innovation Centre, GEIC University of Manchester (UK) consisting in a very low power active radiator to be tested on space conditions. This experiment is the same as the one in HADES-R satellite with updates and improvements. Also, as a challenge made with icMercury, telemetry will send FSK English formatted text messages, part of a history, to be collected.

This satellite is based on the hardware of HADES-D (SO-121, currently being used by hams worldwide for voice contacts) and the next to launch HADES-R. FM satellites are very demanded and appreciated by the ham community because they are easy to use, they don’t require of expensive transceivers and allow continental and even transatlantic contacts in some conditions.

With this satellite we also put into use the amateur VHF and UHF satellite sub-bands helping to secure them for the community in the future. Proposing a UHF downlink and planning a launch on SpaceX Transporter 13 into a 500-600 km polar orbit in Feb 2025. A downlink on 436.666 MHz has been coordinated by the International Amateur Radio Union (IARU).

Nine New TEVEL Satellites Scheduled for Launch

A group of satellites labeled as “TEVEL2” are on the launch manifest for the SpaceX ransporter 13 mission scheduled for launch on March 4. Designated as TEVEL2-1 through TEVE2-9, they are all listed as having a downlink frequency of 436.400 MHz. However, this frequency has not been coordinated with the International Amateur Radio Union (IARU).

One may assume that these satellites will operate in much the same manner as the first series of TEVEL satellites, launched in January of 2022 and now decayed from orbit. These satellites were activated individually and carried FM repeaters with the same 436.400 MHz downlink, and an uplink frequency of 145.970 MHz. However, there is no official word from the satellite sponsors as to their plans for this new series of satellites.

Yet another satellite on the Transporter 13 manifest is NILA, a 3U cubesat built by HEX20Labs and students of Marian Engineering College, both in India. The builders of this satellite requested a UHF downlink for 9600 bps GFSK/AX25 telemetry. However, the IARU declined the request because they deemed the project commercial, and not qualifying for use of amateur frequencies.

UVSQ-Sat NG Scheduled for Launch

Also among the satellites on the manifest for the SpaceX Rideshare 13 launch is the third of a series of French cubesats, named UVSQ-Sat NG — or “Next Generation.” The previous satellites in this series carried amateur radio FM transponders.

Specifically designed to observe essential climate variables, UVSQ-Sat NG is a 6U nanosatellite, meaning that it has the dimensions of six stacked unit cubes, each cube having a standard size of 10 centimetres by. Weighing only 10 kg, UVSQ-Sat NG represents a true concentrate of technology. The satellite is equipped with a sophisticated attitude determination and control system designed to meet a variety of scientific requirements related to the observation of essential climate variables. This addition distinguishes it considerably from its two predecessors, UVSQ-Sat and INSPIRE-Sat 7. In a study published in the journal Remote Sensing Journal, a team of researchers from the Atmospheres Laboratory, Space Observations (LATMOS – CNRS/Sorbonne University / UVSQ), in partnership with industry, described this new space mission as well as its scientific aims. The satellite is scheduled to be launched in 2025.

One of the objectives of UPSQ-Sat NG is to maintain the continuity of the Earth’s Radial Assessment studies initiated by the UVSQ-Sat and INSPIRE-Sat 7 satellites, launched in 2021 and 2023 respectively. The UVSQ-Sat NG mission also involves monitoring concentrations of greenhouse gases, such as carbon dioxide and methane, while analysing their links with infrared radiation emitted by the Earth.

In addition to the methods used to determine the components of the Earth’s Radial Balance sheet from the instruments of the UVSQ-Sat NG satellite, researchers detail the technologies used to extract information on atmospheric gas columns (CO2, CH4, O2, H2O) from data from the miniaturised infrared spectrometer that will be on board UPSQ-Sat NG.

Both scientific and innovative, this research project is primarily an educational tool, and is an exceptional educational platform for students who are actively involved in the design, implementation of the satellite structure, and the establishment of a satellite management and management centre. This programme aims to meet the requirements of enterprises and public bodies in terms of training, development of initial and continuous educational programmes, while at the same time increasing the attractiveness of these training courses. This is in order to ensure the acquisition of the key competences required for the emerging professions of France in 2030.

UVSQ-Sat NG is equipped with several instruments, including radiative sensors (thermopiles with carbon nanotubes) for monitoring incoming solar radiation and outgoing terrestrial radiation. A near-infrared spectrometer is also on board to evaluate atmospheric concentrations of greenhouse gases by making observations in the wavelength range of 1200 to 2000 nm.

In addition, UVSQ-Sat NG carries a high-definition camera designed to take images of the Earth in the visible spectrum. This NanoCam will facilitate the post-processing of spectrometer-based data by ensuring accurate geolocation of observed scenes. It will also offer the possibility of observing the Earth’s edge, thus giving an approximate estimation of the vertical temperature profile of the atmosphere.

A scientific paper published in the journal, Remote Sensing states that, “The Isispace VHF Receiver (RX) operates in the commercial frequency range of 148 to 150.5 MHz, and for amateur frequency coordination, it operates within the frequency range of 145.8 to 146.0 MHz. On the other hand, the Isispace VHF Transmitter (TX) covers the commercial frequency range of 400.15 to 402.0 MHz and, for amateur usage, it spans the range of 435.0 to 438.0 MHz. An audio transponder will also be used with the amateur radio community.”

However, no amateur frequencies have been coordinated with the International Amateur Radio Union (IARU) and no amateur operation has been announced.

Intuitive Machines’ Lunar Lander Beams Back First Images of Earth

The Athena lunar lander manufactured by Houston, Texas aerospace company Intuitive Machines shared its first “selfies” from orbit after launching at 00:16 UTC on Thursday, Feb. 27 from the Kennedy Space Center in Florida.

The images released later Thursday show the six-legged Nova-C lander with Earth in the background. Intuitive Machines shared the photos within about 13 hours of the spacecraft launching to orbit aboard a SpaceX Falcon 9 rocket.

The Athena spacecraft, which is on a mission known as IM-2, is now one of two American-made uncrewed lunar landers on their way to the moon’s surface. Firefly Aerospace, also based in Texas, is operating its own spacecraft named Blue Ghost that is due to attempt a landing early Sunday after about a 45-day voyage.

NASA is the primary customer on both commercial spaceflights, which are due to study different regions of the moon’s surface to pave the way for astronauts to return as early as 2027 under the space agency’s Artemis program. The NASA campaign is treating the moon as a vital pit stop for spacefarers to pause and fuel up ahead of the first crewed missions to Mars.

If all goes to plan, Athena should be landing on the moon’s south pole on Thursday, March 6.

The IM-2 mission is targeting a landing near a plateau known as Mons Mouton, which would be even further south than Intuitive Machines’ first lander, Odysseus, which made history in February 2024. The mesa-like lunar mountain towers over a landscape carved by craters, including the Shackleton Crater – a cold, dark region where water ice and other volatile materials that turn easily into gas are thought to be abundant.

The main experiment onboard Athena is NASA’s PRIME-1 (Polar Resources Ice Mining Experiment-1). The dual instrument composed of both a drill and a mass spectrometer will excavate and measure lunar soil, known as regolith, to detect whether gases and accessible resources are present.

Water ice thought to be abundant in the region, once uncovered, could be extracted and used for drinking, breathing and as a source of hydrogen and oxygen for rocket fuel to make future expeditions to Mars possible, according to NASA.

Other objectives include testing a Nokia LTE 4G communications system and deploying a propulsive drone capable of hopping across the lunar surface.

NASA’s Lunar Trailblazer spacecraft, which launched as a rideshare on the Falcon 9, also began its own separate journey to lunar orbit to map the distribution of the different forms of water on Earth’s only natural satellite.

SpaceX Delays Flight 8 of Starship

SpaceX has pushed the eighth test flight of its Starship megarocket back a few days.

Elon Musk’s company had been targeting Friday (Feb. 28) for Flight 8 of Starship, the biggest and most powerful rocket ever built. But that’s no longer the plan.

“Now targeting to launch Starship’s eighth flight test as soon as Monday, March 3,” SpaceX said in an X post early on Thursday morning (Feb. 27). No reason was given for the delay.

If all goes to plan, Starship will lift off from Starbase, SpaceX’s facility in South Texas, on Monday during a window that opens at 2330 UTC (5:30 p.m. local Texas time).

SpaceX will try for another “chopsticks” catch of Super Heavy, the booster — its third overall, if successful — and Ship, the upper stage, will attempt to deploy mock Starlink satellites on its suborbital trajectory.

Ship will again target a controlled splashdown off Western Australia. Eventually, SpaceX plans to snag the returning upper stage using the launch tower’s chopsticks as well, but the company isn’t ready to try that just yet.

Satellite Shorts From All Over

+ A total lunar eclipse will happen overnight between March 13 and March 14, 2025. It will be the first total lunar eclipse visible anywhere in the world since November 2022, and will also be the first of three happening between 2025 and 2026. During totality — the peak phase of the eclipse — the moon will turn a deep reddish-orange hue, earning it the nickname “Blood Moon.” This effect happens because Earth’s atmosphere scatters shorter wavelengths of light from the sun while allowing longer wavelengths of red and orange hues to be refracted into Earth’s umbra (the darkest part of Earth’s shadow). When these longer wavelengths strike the moon, they can make it appear red, similar to how the sky appears red during sunrise and sunset. Totality will last for an impressive 65 minutes, beginning at 0726 UTC on March 14. (ANS thanks Space.com for the above information.)

+ GOES-19 will replace GOES-16 as the operational GOES-East weather satellite on April 4, 2025. Between 17 March 2025 and 1 April 2025, the GOES-16 satellite will undergo a minor East/West station-keeping maneuver, drifting from its current operational longitude of 75.2°W to a new operational longitude of 75.5°W. During this time, the GOES-East HRIT/EMWIN Broadcast will continue from GOES-16. This 0.3°W shift is expected to induce minimal change in received signal strength for ground stations employing properly aligned small aperture antennas. GOES-19 will also begin its drift maneuver– drifting from 89.5°W to 75.2°W ~1 deg/day drift. On April 1, GOES 19 arrives at 75.2°W, then GOES-19 Post-Drift Product Checkout at new location commences.

HADES-R FM Repeater Activated and Designated Spain-OSCAR 124 (SO-124)

AMSAT-EA has confirmed that the FM repeater aboard the HADES-R satellite has been successfully activated and is now available for amateur radio operators worldwide. The activation took place on February 19th, 2025, following a series of telemetry and command tests to ensure the satellite’s stability and performance. Early reports indicate that the repeater is functioning as expected, providing strong two-way FM voice communications. AMSAT-EA expressed its gratitude to the amateur radio community for submitting telemetry reports, which contributed to the successful commissioning of the satellite.

HADES-R was launched aboard a Falcon 9 rocket from Vandenberg Space Force Base in California on January 14th, 2025, as part of SpaceX’s Transporter-12 mission. Developed by AMSAT-EA, the satellite carries an FM and digital repeater payload designed to provide communication services to amateur radio enthusiasts worldwide. It was deployed from the D-Orbit ION-SCV-016 orbital transfer vehicle on January 22nd and has since been transmitting telemetry data while undergoing operational testing. With the repeater now active, operators can use the uplink frequency of 145.925 MHz and the downlink frequency of 436.885 MHz for communication, with additional support for digital modes such as APRS and FSK telemetry at various data rates.

At the request of AMSAT-EA, AMSAT has officially designated HADES-R as Spain-OSCAR 124 (SO-124) in recognition of its contributions to amateur satellite communications. This designation underscores the satellite’s role in expanding access to space-based communications for the amateur radio community. AMSAT congratulates AMSAT-EA on this achievement and looks forward to the continued success of this and future projects. Meanwhile, amateur radio operators eagerly anticipate the upcoming launch of HADES-ICM on the Transporter-13 mission in March 2025, which will further enhance satellite-based communication capabilities.

ARISS Completes Successful FRAM2Ham Simulation Event Using ISS Radio

The FRAM2Ham ISS Simulation event was a success, bringing together amateur radio enthusiasts and educators from around the world. Over five days, participants engaged in a simulated transmissions from the ISS Service Module Radio to mirror real-world conditions aboard a Dragon spacecraft, which will be used for the upcoming FRAM2 mission. This provided valuable practice for the FRAM2Ham competition. The event was organized and run by ARISS (Amateur Radio on the ISS). The ham radio community followed the request to withhold image postings until the official reveal date of February 20th. By the end of the event, 1,975 images had been submitted, with nearly half coming from students and educators, highlighting the educational impact of the initiative.

The FRAM2 mission will be the first human spaceflight in polar orbit, flying over the North and South poles. Named after the polar exploration ship Fram, the mission aims to highlight exploration, curiosity, and technological progress. A SpaceX Falcon 9 rocket will launch four astronauts from Europe and Australia into orbit for 3-5 days, with a targeted launch in spring 2025. The crew consists of mission commander Chun Wang of Malta, vehicle commander Jannicke Mikkelsen of Norway, pilot Rabea Rogge of Germany, and mission specialist Eric Philips of Australia.

As part of the mission, Rabea Rogge, LB9NJ/KD3AID, will operate the onboard amateur radio system, transmitting SSTV images for a high school and university student competition. These images will also be available to the general public. The FRAM2Ham competition is an experimental radio challenge open to high school and university students, where teams receive SSTV images of three geographical locations transmitted via the onboard ham radio. However, these images will be fragmented and scrambled, requiring participants to piece them together and determine their significance in polar history.

While anyone can receive the images, forming an international team may help solve the puzzle. Participants must correctly identify at least two of the three locations to qualify for prizes, which include QSL cards with space-flown FRAM2 mission stickers. The competition is open to members of educational institutions between the ages of 16-25 years from eligible countries, including Europe (CEPT), the US, Canada, and Australia. The ARISS International team has supported the event by organizing the FRAM2Ham ISS Simulation to help participants develop skills in acquiring images for the competition. For more information, visit the FRAM2HAM website at https://fram2ham.com and the ARISS website at https://ariss.org.

Blue Ghost and Resilience: Private Landers on Course for Lunar Touchdowns

Firefly Aerospace’s Blue Ghost lunar lander has successfully lowered its orbit, bringing it closer to the moon’s surface as it prepares for a historic landing attempt. The spacecraft, part of Firefly’s “Ghost Riders in the Sky” mission, completed a three-minute, 18-second engine burn that reduced its altitude to 75 miles (120 kilometers) above the lunar surface. This maneuver marks a critical phase of the mission as the lander remains in this orbit until its descent begins in less than two weeks.

In a recent update on X, Firefly Aerospace shared a video showcasing Blue Ghost’s new perspective of the lunar surface. The company also warned of intermittent communications blackouts as the lander orbits around the moon’s far side. While on the near side, mission teams are receiving data and refining plans for additional engine burns that will bring Blue Ghost even closer to its intended landing site. The mission is on track for touchdown on March 2nd.

Blue Ghost was launched last month aboard a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Center in Florida. It is part of NASA’s Commercial Lunar Payload Services (CLPS) program, which contracts private companies to deliver scientific instruments and technology demonstrations to the moon. The lander is carrying 10 NASA payloads designed to study the lunar environment and aid future Artemis program missions.

Sharing its launch aboard the Falcon 9 was another lunar lander, Japan-based ispace’s Resilience. This marks ispace’s second attempt at a moon landing after its first mission ended in failure. Resilience is carrying a micro-rover named Tenacious and follows a different trajectory than Blue Ghost, taking a longer, more energy-efficient route. Unlike Blue Ghost, which will attempt a landing within weeks, Resilience’s descent is planned for late May or early June.

Resilience recently performed a lunar flyby on February 14th, passing within 5,220 miles (8,400 kilometers) of the moon’s surface. The maneuver provided a gravity assist that adjusted its trajectory for a smoother arrival into lunar orbit in early May. The lander captured and transmitted a striking image of the lunar surface from 8,972 miles (14,439 kilometers) away, marking a milestone for Japan’s private space industry.

If successful, Blue Ghost will become the second private spacecraft to land on the moon. The lander is set to operate for one full lunar day, equivalent to about two weeks, before losing power as the sun sets. During that time, its NASA payloads will conduct experiments, collect samples, and test new technology. These efforts will contribute to ongoing lunar exploration and preparations for the Artemis program’s future crewed missions to the moon.

The Space Race Below: How Satellites Are Pushing the Limits in VLEO

The race to explore the lowest reaches of space is gaining momentum as companies work to deploy satellites in Very Low Earth Orbit (VLEO). This untapped region, situated just above Earth’s atmosphere, presents both challenges and unprecedented opportunities. While traditional satellites operate at altitudes ranging from hundreds to thousands of miles above Earth, these new “sky skimmers” will navigate much lower, skimming the upper reaches of the atmosphere. The potential advantages of VLEO satellites include enhanced Earth observation, improved communications, and the ability to remain operational in orbit indefinitely through advanced propulsion technologies.

Satellites in VLEO face a difficult balancing act. Unlike their higher-altitude counterparts, these spacecraft must contend with significant atmospheric drag, which constantly threatens to pull them back to Earth. Traditional satellites rely on their horizontal momentum to stay in orbit, but in VLEO, this is not enough. To remain aloft, engineers are exploring Air-Breathing Electric Propulsion (ABEP) systems, which harvest atmospheric molecules and convert them into thrust. If successful, these technologies could allow satellites to sustain themselves indefinitely without the need for large fuel reserves.

Several companies and institutions are actively pursuing this technology. The European Space Agency’s Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) satellite was an early attempt to operate in VLEO, using ion propulsion to counteract drag. More recently, startups such as Kreios Space and Stellar Advanced Concepts have been developing ABEP prototypes, with planned test missions in the coming years. Governments are also getting involved, with the U.S. Department of Defense investing millions in research programs such as Otter, which aims to create operational VLEO satellites.

Different companies are taking varied approaches to overcoming the challenges of VLEO. Redwire, a Florida-based aerospace company, is working on a modular satellite concept called SabreSat, designed to minimize drag and potentially operate for up to seven years in VLEO. The company’s European division is also developing a similar spacecraft, Phantom, under the European Space Agency’s Skimsat program. While Phantom will not use air-breathing propulsion, it will incorporate specialized materials and an aerodynamic design to enhance longevity in low orbit.

The benefits of VLEO satellites extend beyond military and scientific applications. Their close proximity to Earth enables higher-resolution imaging, which could be useful for agriculture, disaster monitoring, and environmental studies. Additionally, communications networks, such as satellite-based internet services, could see a significant boost from VLEO technology. Lower-altitude satellites could provide faster connections and direct-to-device communication capabilities, potentially revolutionizing global internet access.

Despite the promise of VLEO, challenges remain. The region is highly dynamic, with atmospheric conditions influenced by solar activity, which can cause unexpected changes in drag forces. Additionally, while VLEO naturally clears debris by pulling defunct satellites back to Earth, high-energy collisions can still send fragments into higher orbits, creating long-term space debris hazards. As the race to dominate VLEO accelerates, companies and governments must address these risks while capitalizing on the immense potential of this new frontier in space technology.

Beyond L1: Solar Sails Aim to Enhance Space Weather Alerts

Scientists are developing solar sail satellites as a potential early warning system for geomagnetic storms, which can disrupt technological systems on Earth. These sails, which harness sunlight for propulsion, could enhance space travel and improve forecasting for space weather events.

Solar sailing operates similarly to traditional sailing, except it uses photons from the sun instead of wind. “A lot of us have experienced sailing; it’s exactly like that,” said Irfan Azeem, division chief at NOAA’s Office of Space Weather Observations. “Instead of using air, we’re using the light emitted by the sun to propel our satellites.”

Unlike traditional propulsion systems, solar sails offer a cost-effective means of maneuvering satellites without fuel. “This is a very novel technology,” Azeem added. “We have traditionally relied on propulsion to take satellites from one place to another, and solar sails are providing a new, efficient way to travel in space.” NOAA’s satellites play a vital role in space weather monitoring, gathering data that helps issue warnings for potentially disruptive solar flares.

Currently, satellites like NASA’s Advanced Composition Explorer and NOAA’s Deep Space Climate Observatory track the solar wind, a stream of charged particles from the sun that can interact with Earth’s magnetic field. Although current monitoring provides some advance notice of geomagnetic storms, scientists aim to improve lead times by positioning satellites closer to the sun through NOAA’s Space Weather Next program.

One major advantage of solar sails is their ability to travel beyond the Lagrange One Point (L1), a location about 932,000 miles (1.5 million kilometers) from Earth where satellites currently observe the sun. “L1 provides a semistable orbit for persistent sun monitoring,” Azeem explained. “But if you want to go further, you need chemical rockets. Solar sails offer a cost-effective alternative for moving upstream.” By positioning satellites further ahead in the solar wind, NOAA estimates they could improve geomagnetic storm lead times by 50%.

At the American Meteorological Society’s annual meeting, NOAA provided updates on the Solar Cruiser project, a collaboration with NASA. The full-scale solar sail, set to span 17,793 square feet (1,653 square meters), is under construction. The spacecraft will include four sails, each built separately, with completion expected by February 2026. NOAA aims to secure a rideshare launch by 2029. “I’m most excited about the complexity of integrating different disciplines,” Azeem said. “Advances in material science and other fields are helping us push space weather monitoring to the next level.”

Changes to AMSAT-NA TLE Distribution for February 21, 2025

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 US 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

+ In 2024, NASA’s Search and Rescue technologies contributed to saving 407 lives in the U.S., including 314 at sea, 41 in aviation incidents, and 52 through personal locator beacons. These efforts are part of the international Cospas-Sarsat satellite-aided search and rescue system, which has helped save over 50,000 lives worldwide since 1982. Using GPS satellites, emergency beacons transmit distress signals to the Cospas-Sarsat network, enabling first responders to locate and rescue those in need. NASA’s Search and Rescue Office, a division of the SCaN Program, has been involved in rescue operations since 1979 and continues to enhance beacon technology for both Earth-based and space missions. The Advanced Next-Generation Emergency Locator (ANGEL) beacon is being developed to support crew recovery efforts, including for Artemis missions returning from deep space. NASA collaborates with NOAA, the U.S. Coast Guard, the U.S. Air Force, and other agencies to ensure rapid response and rescue operations across land, sea, and air. (ANS thanks NASA for the above information)

+ NASA and SpaceX have decided to swap Crew Dragon spacecraft for the Crew-10 mission, opting to use the previously flown Endurance instead of a newly built capsule to prevent further delays. Endurance, which had been assigned to the private Ax-4 mission, will now support Crew-10, allowing the launch to be accelerated from late March to no earlier than March 12th. The original delay stemmed from setbacks in assembling and testing the new Crew Dragon, pushing the Crew-10 launch from February to March. Crew-9, currently on the ISS, will return a few days after Crew-10 arrives, bringing back NASA astronauts Suni Williams and Butch Wilmore, whose extended stay became a political topic after Elon Musk and former President Trump criticized the delay. Williams, however, dismissed claims that she and Wilmore were “abandoned,” stating they were safe and had all necessary resources aboard the station. The change in spacecraft does not alter the Crew-10 lineup, commanded by NASA astronaut Anne McClain, but it raises uncertainty about the Ax-4 mission timeline, which was originally planned for April. (ANS thanks SpaceNews for the above information)

+ NASA’s SPHEREx telescope, set to launch no earlier than February 27th aboard a SpaceX Falcon 9 rocket, will explore cosmic reservoirs of life’s building blocks. It will scan space for water, carbon dioxide, and carbon monoxide frozen onto interstellar dust grains, which exist in molecular clouds where stars and planets form. Scientists believe these icy reservoirs played a crucial role in shaping Earth’s oceans and other celestial bodies’ water content. Unlike previous telescopes that analyzed specific regions, SPHEREx will conduct an extensive 3D spectral survey, identifying ice compositions across different environments. The mission aims to resolve longstanding questions about molecular cloud chemistry, particularly why previous missions, like SWAS, detected less gaseous water than expected. By working alongside telescopes such as Webb, SPHEREx will refine our understanding of planet formation and the distribution of essential life-building compounds across the universe. (ANS thanks SpaceDaily for the above information)

+ SpaceX is preparing for its eighth Starship launch (IFT-8) by conducting crucial static fire tests at its Starbase facility in Texas. The company recently ignited all 33 Raptor engines on the Super Heavy booster and completed a dynamic engine test for the Starship stage to simulate various in-flight conditions. These tests mark a key milestone before the vehicle’s final stacking, where the two massive components will be joined for launch. Once stacked, the fully integrated Starship and Super Heavy system will stand an impressive 403 feet (123 meters) tall, making it the most powerful rocket ever built. Starship’s previous test flight, IFT-7, had mixed results, with a successful booster catch but a loss of communication with the Starship stage, which ultimately disintegrated over the Caribbean. SpaceX continues to refine the vehicle with each iteration, incorporating new hardware to improve performance and reliability. While IFT-8 could launch by the end of February, the schedule remains dependent on FAA approval and final preparations. (ANS thanks Space.com for the above information)

Current Active AMSAT Engineering Projects

AMSAT’s GOLF project is targeting a launch NET (no earlier than) 1Q 2026 for GOLF-TEE, a 3U CubeSat carrying a V/u linear transponder, an X band SDR based downlink, and an active attitude determination and control system. The follow-on GOLF-1 is currently targeted for a launch NET 1Q 2027.

AMSAT’s Fox Plus project is also proceeding towards being ready for a launch of a 1U CubeSat (Fox-Plus-A) with a V/u linear transponder. AMSAT’s Fox-Plus-B is also proceeding with the AMSAT XBT as the core transponder technology. AMSAT’s XBT is intended to break down the barrier between linear and FM transponders using modern signal processing and SDR. It will be capable of providing simultaneous multiple channel operation using multiple modes. All” modes will be simultaneously supported from CW through SSB through narrow band FM through PSK31 (BPSK, QPSK and such) and even SSTV. The signal processing portion of the transponder will be reconfigurable in orbit and the initial design is as a traditional U/v (non-inverting) configuration.

AMSAT’s Fox-Plus-B satellite is also expected to fly AMSAT’s PACSAT payload.

AMSAT-EA’s HADES-R Successfully Deployed and Transmitting Telemetry

The HADES-R amateur radio satellite, operated by AMSAT-EA, has been successfully deployed and is functioning as expected. According to AMSAT-EA’s update on January 23rd, the satellite is transmitting telemetry data, and the initial health reports indicate that it is in good condition. The team is actively receiving data and preparing to transition the satellite into repeater mode once all necessary checks are completed. Amateur radio operators worldwide are encouraged to share their telemetry reports to assist in confirming its operational status.

Deployment occurred on January 22nd at 15:42 UTC from the D-Orbit ION-SCV-016 orbital transfer vehicle (OTV) after launching on January 14th aboard a SpaceX Falcon 9 rocket as part of the Transporter-12 mission from Vandenberg Space Force Base. The mission carried 131 payloads, including amateur radio satellites HADES-R and PARUS-T1. Due to the large number of satellites onboard, deployments were staggered over several days. Early signals were reported by amateur operators, but official confirmation from AMSAT-EA followed later. Transmissions began shortly after deployment, though the FM repeater remains inactive as testing and validation processes continue.

Designed to provide FM voice repeater capabilities, the satellite also supports various digital modes, including FSK telemetry and APRS at up to 1200 bps. It features a downlink frequency of 436.888 MHz, as coordinated by the International Amateur Radio Union (IARU). While FM voice is its primary mission, it will also transmit experimental data and FSK telemetry. The uplink frequency is 145.925 MHz, supporting FM voice and various digital modes, including AX.25 and APRS. The FM repeater will operate without requiring a subtone, activating via squelch level.

As part of AMSAT-EA’s ongoing efforts to expand amateur radio satellite operations, this spacecraft is the first of two planned replacements for HADES-D (SO-121). The second, HADES-ICM, is expected to launch on the upcoming Transporter-13 mission in March 2025. Both satellites will provide FM and digital communication options, allowing amateur operators to engage in long-distance contacts. Additionally, HADES-ICM will host an experimental payload from the University of Manchester’s Smart IR/Graphene Engineering Innovation Centre (GEIC), testing a low-power active radiator under space conditions. AMSAT-EA has urged the amateur radio community to continue monitoring transmissions and sharing received telemetry data as the satellite progresses towards full operational capability.

Blue Origin Simulates Lunar Gravity on Landmark New Shepard Flight

Blue Origin successfully launched its NS-29 mission on February 4th, marking a significant milestone in suborbital research. The mission, which lifted off from the company’s West Texas launch site at 11 a.m. EST (16:00 UTC), was originally scheduled for January 28th but was delayed due to weather and technical issues. This flight was the 29th for the reusable New Shepard vehicle and featured a unique capability: the simulation of lunar gravity in suborbital space.

The NS-29 mission proceeded as planned, with both the booster and the crew capsule executing safe returns to Earth. The booster performed a controlled vertical landing on the designated pad, while the capsule descended under parachutes, touching down in the West Texas desert approximately 10 minutes after launch. However, one of the capsule’s three parachutes did not fully open. Blue Origin officials assured viewers during the live broadcast that the spacecraft is designed to land safely even if not all parachutes fully deploy.

A key feature of this mission was its ability to generate lunar gravity forces—a first for New Shepard. The capsule achieved this by rotating about 11 times per minute for two minutes using its reaction-control thrusters. This capability was developed to support research on lunar-related technologies, benefiting the 30 payloads aboard the spacecraft. Among these, 29 experiments were specifically designed to test innovations applicable to the Moon’s environment.

Blue Origin categorized these experiments into six focus areas: in-situ resource utilization, dust mitigation, advanced habitation systems, sensors and instrumentation, small spacecraft technologies, and entry, descent, and landing methods. Many of these experiments were backed by NASA’s Flight Opportunities Program, underscoring the space agency’s commitment to developing technology for lunar exploration. With the Artemis program aiming for long-term human presence on the Moon, missions like NS-29 provide valuable data to refine critical systems for future lunar operations.

Notable NASA-supported experiments aboard NS-29 included the Electrostatic Dust Lofting project, which examined how lunar dust becomes electrically charged and moves when exposed to ultraviolet light. Another key experiment, the Lunar-g Combustion Investigation, studied fire behavior in lunar gravity compared to Earth’s, helping to enhance safety in future lunar habitats. Other experiments tested propellant management in low gravity, soil analysis tools, and small satellite propulsion systems, all contributing to advancing space exploration technologies.

New Shepard, named after astronaut Alan Shepard, has been operational since its first uncrewed flight in April 2015. The vehicle made history in 2021 by carrying Jeff Bezos and three others on its first crewed flight. While primarily known for space tourism, with nine of its 29 flights carrying passengers, the system continues to play a critical role in scientific research. The successful NS-29 mission not only demonstrated Blue Origin’s ability to simulate lunar gravity but also reinforced its contribution to advancing space technology in support of NASA’s lunar ambitions.

Interlune Aims to Mine Lunar Helium-3 for Quantum Computing on Earth

Interlune, a Seattle-based startup founded by former Blue Origin technologists, is aiming to harvest Helium-3 from the moon to support quantum computing applications on Earth. Helium-3, a rare isotope deposited into the lunar regolith by solar wind, was first identified in samples brought back by NASA’s Apollo missions. While the potential applications of Helium-3 have intrigued scientists for years, recent astrogeological research highlights significant challenges in extracting the isotope. The U.S. Geological Survey (USGS) suggests that obtaining commercially viable amounts would require processing millions of tons of lunar regolith, a task comparable to large-scale mining operations on Earth.

Despite these hurdles, Interlune CEO Rob Meyerson remains optimistic. The company envisions an extraction system operating like an agricultural setup, with five harvesters each the size of a large SUV. Meyerson acknowledges that it will take years before the company sees a financial return, but he emphasizes the growing demand for Helium-3 in quantum computing. This isotope plays a critical role in cooling superconducting quantum computers to temperatures close to absolute zero. With quantum computing companies recognizing the need for a stable Helium-3 supply, Interlune believes now is the time to act.

Interlune is not the first to consider the commercial potential of lunar Helium-3. Apollo 17 astronaut and Interlune’s executive chairman, Jack Schmitt, has long advocated its use in nuclear fusion reactors. However, investment interest has shifted towards quantum computing applications, which promise quicker returns. Beyond computing, Helium-3 has other potential uses, including medical imaging and radiation detection. Interlune hopes to eventually supply tens of kilograms per year, a goal that Meyerson believes is both realistic and financially sustainable given current market prices of around $20 million per kilogram.

However, some experts remain skeptical about the feasibility of large-scale Helium-3 extraction from the moon. Laszlo Keszthelyi, a research geologist at the USGS Astrogeology Science Center, notes that lunar Helium-3 concentrations range from just 2.4 to 26 parts per billion in Apollo samples. Given these figures, obtaining a single kilogram would require processing between 100,000 and 1 million tons of lunar soil. Keszthelyi stops short of dismissing the endeavor outright, stating that the moon does contain resources—it is merely a question of how they can be effectively utilized.

To address these concerns, Interlune is planning a resource development mission in 2027 to analyze Helium-3 concentrations at a potential mining site. This mission will be followed by a pilot plant in 2029 to demonstrate extraction and processing on the lunar surface. The company’s initial lunar mission will launch through NASA’s Commercial Lunar Payload Services initiative. Interlune is actively securing funding, having already raised $18 million, with plans for another round of fundraising in the near future.

While profitability remains uncertain, experts acknowledge that Interlune’s success will depend on the efficiency of its extraction methods. Chris Dreyer from the Colorado School of Mines notes that certain minerals trap more Helium-3 than others, potentially increasing yield in select locations. However, large-scale excavation will be necessary, posing technical challenges, particularly with lunar dust. Despite these obstacles, Dreyer believes that iterative development—designing, testing, and improving equipment—could make Interlune’s ambitions feasible. As advances in space exploration continue, the prospect of mining Helium-3 on the moon is becoming an increasingly tangible reality.

Changes to AMSAT-NA TLE Distribution for February 7, 2025

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 US 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.

The following satellite has been added to this week’s AMSAT TLE distribution:
HyperView 1G (RS66S) NORAD Cat ID 61772 Downlink 436.540 MHz
OBJECT BA (ZIMSAT 2) NORAD Cat ID 71783 Downlink 437.050 MHz

Many times a school may make a last minute decision to do a Livestream or run into a last minute glitch requiring a change of the URL but we at ARISS may not get the URL in time for publication. You can always check https://live.ariss.org/ to see if a school is Livestreaming.

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.

Satellite Shorts From All Over

+ AO-73 was switched back to full-time transponder mode on February 3rd, 2025. The U/V linear transponder is now operating 24/7 after a month-long period of telemetry collection on the satellite’s electrical power system. While some signs of reduced battery capacity are present, the two Lithium-Ion cells continue to perform well, supporting full transponder operation throughout the orbit. AO-73 features an inverting SSB/CW transponder with an uplink passband from 435.150 to 435.130 MHz (LSB) and a downlink passband from 145.950 to 145.970 MHz (USB). With the transponder active, the satellite also transmits BPSK telemetry on 145.935 MHz at 40mW. The collected telemetry data helps assess the long-term health of the 11-year-old satellite.

+ NASA has confirmed the crew for Axiom Mission 4, set to launch no earlier than spring 2025 aboard a SpaceX Dragon spacecraft from Kennedy Space Center. The mission will be commanded by former NASA astronaut Peggy Whitson, with ISRO astronaut Shubhanshu Shukla as pilot and ESA’s Sławosz Uznański-Wiśniewski and Hungary’s Tibor Kapu as mission specialists. Once docked at the International Space Station, the crew will spend up to 14 days conducting science, outreach, and commercial activities. This mission includes the first ISRO astronaut aboard the station and the first astronauts from Poland and Hungary to stay there. NASA sees private astronaut missions as a way to expand access to space and support commercial activity in low Earth orbit. As the agency shifts focus to deep space exploration through Artemis missions, partnerships with private companies help maintain a human presence in space and support research in microgravity.

+ Indian Space Research Organization’s (ISRO) NVS-02 navigation satellite, launched on January 28th aboard a Geostationary Satellite Launch Vehicle (GSLV) Mark 2 rocket, was intended to replace the IRNSS-1E satellite in geostationary orbit as part of India’s NavIC navigation system. However, ISRO confirmed on February 2nd that the satellite’s onboard propulsion system failed due to oxidizer valves not opening, preventing it from reaching its intended orbit. As a result, NVS-02 remains stuck in an elliptical transfer orbit with a perigee of 165 kilometers (103 miles) and an apogee of 37,582 kilometers (23,354 miles), making it vulnerable to reentry due to atmospheric drag. While the spacecraft’s solar panels and other systems are functioning normally, ISRO is exploring alternative mission strategies to utilize it in its current orbit. The 2,250-kilogram (4,960-pound) satellite was the second of five planned NavIC satellites aimed at enhancing regional navigation services. Its failure raises concerns about the future deployment of the NavIC system, and it remains unclear if any backup propulsion systems could adjust its orbit to prevent early reentry.

+ AstroForge, a U.S.-based asteroid mining company, has identified asteroid 2022 OB5 as the target for its upcoming Mission 2, Odin, set to launch in February 2025 aboard a SpaceX Falcon 9 rocket. Odin will serve as a scouting spacecraft, flying as a secondary payload alongside Intuitive Machines’ IM-2 lunar lander, and will separate after the rocket’s upper stage fires for the moon. The spacecraft is expected to take about 300 days to reach the asteroid, where it will conduct a flyby to gather crucial imagery and assess the rock’s mining potential. This mission paves the way for AstroForge’s next endeavor, Vestri, which aims to land on the asteroid and initiate resource extraction, potentially launching in late 2025 as part of another rideshare mission. AstroForge, founded in January 2022, seeks to develop sustainable methods for mining precious metals from asteroids, although its first mission, Brokkr-1, launched in April 2023, failed to activate its onboard refinery technology. The company has also secured a contract with Stoke Space for future launches aboard the Nova rocket to support its ambitious mining goals. (ANS thanks Space.com for the above information)
