<p><b><span style="font-size:18.0pt;font-family:"Segoe UI",sans-serif">HADES-R FM Repeater Activated and Designated Spain-OSCAR 124 (SO-124)<o:p></o:p></span></b></p>
<p><span style="font-family:"Segoe UI",sans-serif">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.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">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.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">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.<o:p></o:p></span></p>

<h2><span style="font-family:"Segoe UI",sans-serif">ARISS Completes Successful FRAM2Ham Simulation Event Using ISS Radio<o:p></o:p></span></h2>
<p><span style="font-family:"Segoe UI",sans-serif">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.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">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.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">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.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">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

<h2><span style="font-family:"Segoe UI",sans-serif">Blue Ghost and Resilience: Private Landers on Course for Lunar Touchdowns<o:p></o:p></span></h2>
<p><span style="font-family:"Segoe UI",sans-serif">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.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">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.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">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.<o:p></o:p></span></p>

<p><span style="font-family:"Segoe UI",sans-serif">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.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">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.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">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.<o:p></o:p></span></p>

<h2><span style="font-family:"Segoe UI",sans-serif">The Space Race Below: How Satellites Are Pushing the Limits in VLEO<o:p></o:p></span></h2>
<p><span style="font-family:"Segoe UI",sans-serif">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.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">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.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">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.<o:p></o:p></span></p>
<p class="MsoNormal" align="center" style="text-align:center"><a href="https://www.amsat.org/wordpress/wp-content/uploads/2025/02/Stellar-Advanced-Concepts-Air-Breathing-Electric-Propulsion.jpg"><span style="color:blue;text-decoration:none"><img border="0" width="1024" height="576" style="width:10.6666in;height:6.0in" id="_x0000_i1048" src="https://www.amsat.org/wordpress/wp-content/uploads/2025/02/Stellar-Advanced-Concepts-Air-Breathing-Electric-Propulsion.jpg"></span></a><o:p></o:p></p>
<p class="MsoNormal" align="center" style="text-align:center"><span style="font-size:9.0pt;font-family:"Segoe UI",sans-serif">Air-breathing propulsion technology could enable satellites to remain in Very Low Earth Orbit indefinitely. [Credit:
<a href="https://www.stellar-ac.com/">Stellar Advanced Concepts</a>]<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">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.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">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.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">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.<o:p></o:p></span></p>

<h2><span style="font-family:"Segoe UI",sans-serif">Beyond L1: Solar Sails Aim to Enhance Space Weather Alerts<o:p></o:p></span></h2>
<p><span style="font-family:"Segoe UI",sans-serif">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.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">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."<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">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.<o:p></o:p></span></p>

<a href="https://www.nasa.gov/marshall/">NASA/Marshall Space Flight Center</a>]<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">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.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">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%.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">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."<o:p></o:p></span></p>

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 <a href="https://www.amsat.org/keplerian-elements-resources/">
https://www.amsat.org/keplerian-elements-resources/</a>.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">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.<o:p></o:p></span></p>
<p><em><span style="font-family:"Segoe UI",sans-serif">This week there are no additions or deletions to the AMSAT TLE distribution.</span></em><span style="font-family:"Segoe UI",sans-serif"><o:p></o:p></span></p>

<h2><span style="font-family:"Segoe UI",sans-serif">Satellite Shorts From All Over<o:p></o:p></span></h2>
<p><span style="font-family:"Segoe UI",sans-serif">+ 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 <a href="https://www.nasa.gov/">

<p><span style="font-family:"Segoe UI",sans-serif">+ 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

<p><span style="font-family:"Segoe UI",sans-serif">+ 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.

<p><span style="font-family:"Segoe UI",sans-serif">+ 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 <a href="https://www.space.com/">
