<h2><span style="font-family:"Segoe UI",sans-serif">Fram2 Mission Blends Polar Orbit, Amateur Radio, and Private Spaceflight<o:p></o:p></span></h2>
<p><span style="font-family:"Segoe UI",sans-serif">SpaceX launched the Fram2 private astronaut mission on Monday, March 31st, marking a new chapter in commercial spaceflight. The Crew Dragon spacecraft Resilience carried four private astronauts into a polar
orbit—making it the first crewed mission to fly directly over both the North and South Poles. After three and a half days in orbit, the spacecraft splashed down safely in the Pacific Ocean off the coast of California on Friday, April 4th.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">One of the mission’s standout features was Fram2Ham, an amateur radio initiative led by mission pilot Rabea Rogge (LB9NJ/KD3AID), a robotics researcher from Germany. On April 1st, just hours after reaching
orbit, Rogge conducted the first amateur radio contact ever made from a Crew Dragon spacecraft. Speaking on 437.550 MHz, she answered questions from students at Technische Universität Berlin (TU Berlin) during a live-streamed session focused on STEM topics.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">The mission also featured slow-scan television (SSTV) transmissions sent by Rogge using an ICOM IC-705 transceiver. Amateur radio operators around the world tuned in and successfully decoded images sent from
orbit. The images were submitted to an online gallery maintained by ARISS (Amateur Radio on the International Space Station), with over 1,100 general entries and more than 110 from student STEM teams submitted during the mission.<o:p></o:p></span></p>

<p><span style="font-family:"Segoe UI",sans-serif">The Fram2Ham experiment demonstrated that meaningful amateur radio operations can be carried out from commercial crew vehicles using compact, battery-powered equipment. ARISS called the effort a breakthrough
for ham radio in human spaceflight, noting that the success of Fram2Ham opens the door to future communications experiments aboard non-governmental orbital missions and commercial space stations.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">Fram2 also included operational tests with future exploration goals in mind. Following splashdown, the astronauts exited the spacecraft without external help to simulate autonomous egress procedures that may
be necessary on lunar or Martian surfaces. The hands-on, self-directed nature of the Fram2Ham project paralleled this emphasis on independence, with Rogge managing transmissions without ground crew assistance.<o:p></o:p></span></p>

Chun Wang</a>]<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">The mission saw strong participation from the amateur radio community. The Live OSCAR Status Page on the AMSAT web site received a record 496 reception reports during the mission, more observations than any
other spacecraft in a 4-day period since the page's inception. Although several operators attempted to receive signals during the reentry phase, none succeeded, as the capsule entered a plasma blackout. Still, engagement across the amateur radio world was
described as historic.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">Fram2 was organized and funded by Chun Wang, a Malta-based cryptocurrency entrepreneur originally from China, who also served as the mission commander. He was joined by Rogge, Norwegian cinematographer Jannicke
Mikkelsen as vehicle commander, and Australian polar explorer Eric Philips as mission specialist and medical officer. The team conducted 22 research experiments in orbit, including medical imaging, materials testing, and biological studies.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">As the first crewed mission to reach a 90-degree orbital inclination, Fram2 provided rare views of polar auroras and remote Arctic landscapes. For Wang, the mission fulfilled a childhood curiosity about the
polar regions; for the broader space community, it demonstrated how private spaceflight can combine scientific research, technical innovation, and public outreach—including a successful amateur radio experiment that brought signals from orbit to Earthbound
listeners around the globe.<o:p></o:p></span></p>

<h2><span style="font-family:"Segoe UI",sans-serif">Spectrum’s Fiery Debut Marks Bold First Step for Isar Aerospace<o:p></o:p></span></h2>
<p><span style="font-family:"Segoe UI",sans-serif">The inaugural flight of Isar Aerospace's Spectrum rocket ended just 40 seconds after liftoff on Sunday, March 30th, with the vehicle crashing into the sea off Norway’s Andøya Spaceport. The rocket, intended
to be the first orbital-class launcher developed by a private European company, lost control shortly after takeoff and triggered its flight termination system before plummeting into the Arctic waters in a fiery explosion.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">Isar Aerospace officials acknowledged the failure but emphasized the value of the flight. “Today, we know twice as much about our launch system as yesterday before launch,” said Daniel Metzler, Isar’s co-founder
and CEO. The company released multiple replays of the short flight, including a drone-captured video, underscoring a level of transparency uncommon in the space launch industry. Metzler praised the team’s achievement, framing the test as a crucial step forward
in a long-term development process.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">The Spectrum rocket lifted off at 1030 UTC, generating over 150,000 pounds of thrust from its nine engines fueled by liquid propane and liquid oxygen. Trouble emerged about 15 seconds into the flight as the
rocket began to oscillate and tumble, eventually flipping upside-down. With the rocket’s propellant tanks still nearly full, its impact created a massive fireball visible from the snowy Andøya landscape. No injuries were reported, and the launch pad remained
intact.<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/2025/04/Isar-Aerospace-Spectrum-Initial-Launch-Attempt.png"><span style="text-decoration:none"><img border="0" width="1024" height="576" style="width:10.6666in;height:6.0in" id="_x0000_i1068" src="https://www.amsat.org/wordpress/wp-content/uploads/2025/04/Isar-Aerospace-Spectrum-Initial-Launch-Attempt-1024x576.png"></span></a><o:p></o:p></p>

<p><span style="font-family:"Segoe UI",sans-serif">The mission carried no commercial payload, a deliberate decision given the anticipated risk. The goal was to gather performance data during Spectrum’s first powered flight. Officials at Isar Aerospace had long
signaled that reaching orbit on the first attempt was unlikely. By preserving the launch site and capturing valuable telemetry, the company achieved what it described as a successful test despite the dramatic conclusion.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">Founded in 2018, Isar Aerospace has raised over 400 million euros in private and institutional funding, making it the most well-capitalized among Europe’s emerging private launch companies. Supporters include
the European Space Agency, Germany’s government, and the NATO Innovation Fund. ESA director general Josef Aschbacher praised the flight as a vital learning opportunity, while German vice chancellor Robert Habeck hailed the launch as evidence of Europe’s growing
technological independence.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">Isar is already building its next two rockets and plans to iterate quickly, following a strategy modeled after SpaceX’s fast-paced test-and-repair cycle. While the loss of the first Spectrum rocket marks a
setback, company officials maintain that success lies not in perfection but in progress. “We’re super happy,” Metzler said. “Now it’s time to analyze all data, learn, iterate, and be back on the launch pad as soon as possible.”<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">"We’re super happy," Metzler said in a press call after Sunday's flight. "It’s a time for people to be proud of, and for Europe, frankly, also to be proud of."<o:p></o:p></span></p>

<h2><span style="font-family:"Segoe UI",sans-serif">LuGRE Demonstrates Viability of GPS Navigation on the Moon<o:p></o:p></span></h2>
<p><span style="font-family:"Segoe UI",sans-serif">NASA and the Italian Space Agency have achieved a historic milestone with the successful conclusion of the Blue Ghost mission, which delivered the Lunar GNSS Receiver Experiment (LuGRE) to the Moon. LuGRE became
the first technology demonstration to acquire and track Earth-based navigation signals from the lunar surface, proving that Global Navigation Satellite System (GNSS) signals—including GPS and Galileo—can be used to support autonomous navigation on the Moon.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">The ability to receive and process GNSS signals approximately 225,000 miles from Earth opens new possibilities for future lunar and deep space missions. By reducing reliance on Earth-based tracking, missions
like NASA’s Artemis program could benefit from real-time, onboard navigation systems similar to those used on Earth.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">LuGRE was delivered by Firefly Aerospace’s Blue Ghost lander, which touched down on the Moon on March 2nd. Science operations began shortly after landing, and by 2 a.m. EST on March 3rd, the LuGRE payload had
successfully acquired and tracked GNSS signals from the Moon's surface, achieving a navigation fix and marking a first in space exploration.<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/2025/04/NASA-Succesfully-Aquires-GNSS-on-Moon.jpg"><span style="text-decoration:none"><img border="0" width="1024" height="576" style="width:10.6666in;height:6.0in" id="_x0000_i1066" src="https://www.amsat.org/wordpress/wp-content/uploads/2025/04/NASA-Succesfully-Aquires-GNSS-on-Moon-1024x576.jpg"></span></a><o:p></o:p></p>

<a href="https://www.nasa.gov/">NASA</a>/Dave Ryan]<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">The Blue Ghost mission operated for 14 days, completing its objectives before the onset of lunar night. During that time, LuGRE functioned in near-continuous mode, gathering valuable data and demonstrating
the viability of GNSS-based navigation on the Moon. The mission also marked a milestone for the Italian Space Agency, as LuGRE was its first hardware to operate successfully on the lunar surface.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">In addition to its surface accomplishments, LuGRE set multiple records during its journey. On January 21st, it acquired GNSS signals at a record-breaking altitude of 209,900 miles from Earth—surpassing the
previous high set by NASA’s Magnetospheric Multiscale Mission. The payload later received signals from 243,000 miles away in lunar orbit on February 20th, confirming that GNSS signals can be used not only on the Moon but throughout cislunar space.<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">LuGRE was developed through a partnership involving NASA’s Goddard Space Flight Center, the Italian Space Agency, Italian industry partner Qascom, and Politecnico di Torino. The mission’s success demonstrates
the growing potential of Earth-based navigation systems to support autonomous space exploration well beyond Earth orbit.<o:p></o:p></span></p>

<h2><span style="font-family:"Segoe UI",sans-serif">Changes to AMSAT-NA TLE Distribution for April 4, 2025<o:p></o:p></span></h2>
<p><span style="font-family:"Segoe UI",sans-serif">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 <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">The following satellites have been added to this week's AMSAT TLE distribution:</span></em><span style="font-family:"Segoe UI",sans-serif"><br>
<em><span style="font-family:"Segoe UI",sans-serif">JINJUSat 1B NORAD Cat ID 63210 Downlink 435.185 MHz</span></em><br>
<em><span style="font-family:"Segoe UI",sans-serif">NUSHSAT 1 NORAD Cat ID 63211 Downlink 436.200 MHz</span></em><br>
<em><span style="font-family:"Segoe UI",sans-serif">DRAGON Fram2 NORAD Cat ID 63427 Downlink 437.550 MHz</span></em><o:p></o:p></span></p>
<p><em><span style="font-family:"Segoe UI",sans-serif">Please note that the elements provided for "DRAGON Fram2" are provided by the US Space Force, while "Fram2Ham" are derived from state vectors provided by SpaceX and converted to TLE by ARISS. AMSAT TLE
for "Fram2Ham" continue to use the provisional object number 90000. There is no practical difference between the element sets for Amateur Radio use. Hats off to SpaceX for a precision orbital injection, the inclination of this polar orbit is 90.00 degrees.</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">+ Didn't get enough SSTV last week? The International Space Station will be transmitting special Slow Scan Television (SSTV) images to celebrate Cosmonautics Day, which honors Yuri Gagarin's historic first
spaceflight on April 12, 1961. The SSTV event is organized by ARISS (Amateur Radio on the International Space Station) and will run from April 11 through the weekend. A total of 12 images will be broadcast in PD120 mode on the standard downlink frequency of
145.800 MHz FM. Enthusiasts around the world can receive these images using a VHF radio or SDR, along with SSTV decoding software such as MMSSTV, RX-SSTV, or Robot36. This is a great opportunity for amateur radio operators and space fans alike to collect commemorative
images directly from orbit. Be sure to check ISS pass times for your location so you don’t miss the transmissions. (ANS thanks

<p><span style="font-family:"Segoe UI",sans-serif">+ NASA astronaut Jonny Kim, along with Roscosmos cosmonauts Sergey Ryzhikov and Alexey Zubritsky, will launch aboard the Soyuz MS-27 spacecraft to the International Space Station on Tuesday, April 8th, at 05:47
UTC from the Baikonur Cosmodrome in Kazakhstan. After a three-hour, two-orbit journey, they are scheduled to dock at the station’s Prichal module at approximately 09:03 UTC and join the Expedition 72/73 crew. This marks the first spaceflight for Kim and Zubritsky,
and the third for Ryzhikov, with the mission lasting about eight months. They will work alongside international astronauts and cosmonauts to advance scientific research aboard the ISS. NASA will provide live coverage of the launch, docking, and hatch opening
events on NASA+, including hatch opening at approximately 11:20 UTC. This mission continues the ISS’s legacy as a vital platform for long-duration spaceflight research, supporting NASA’s broader goals, including the Artemis campaign and future missions to
Mars. (ANS thanks <a href="https://www.nasa.gov/">NASA</a> for the above information)<o:p></o:p></span></p>
<p><span style="font-family:"Segoe UI",sans-serif">+ On March 22, 2025, a team of amateur radio astronomers used the historic Dwingeloo telescope to successfully bounce a radio signal off Venus and receive its echo, marking only the second amateur Earth-Venus-Earth
(EVE) bounce ever achieved. The first amateur EVE was accomplished in 2009 by AMSAT-DL using the 20-meter radio telescope at the Bochum Observatory. During this recent experiment, Venus was at its closest approach to Earth—about 42 million kilometers away—allowing
for a 280-second round-trip signal travel time. The team transmitted a 278-second tone at 1299.5 MHz and repeated the cycle four times, with both Dwingeloo and the more sensitive Stockert telescope successfully receiving the echoes. Signal analysis, including
Doppler corrections and frequency binning, showed detections with up to 9.2 sigma significance when combining data from both sites. Although a transmitter issue cut short plans for more complex signal testing, the team looks forward to continuing the experiment
during the next Venus conjunction in October 2026, with support from organizations like the Deep Space Exploration Society, Open Research Institute, and many dedicated volunteers. (ANS thanks

<p><span style="font-family:"Segoe UI",sans-serif">+ NASA’s Parker Solar Probe has completed its second daring flyby of the sun, coming within 3.8 million miles of its surface at speeds nearing 430,000 mph, while collecting valuable data on solar wind and the
sun’s corona. The spacecraft operated autonomously during the approach, using four specialized instruments to study the sun's outer atmosphere. This mission marks another historic milestone in solar science, as Parker continues to rewrite what we know about
our star and helps scientists better predict space weather. The spacecraft’s extreme performance is made possible by cutting-edge technologies, including a heat shield, self-cooling solar arrays, and autonomous systems. In recognition of these innovations,
the Parker Solar Probe team—comprising NASA, the Johns Hopkins Applied Physics Lab, and over 40 partners—was awarded the prestigious 2024 Robert J. Collier Trophy. Launched in 2018 and managed under NASA’s Living With a Star program, the probe is expected
to make another close approach in June, continuing its groundbreaking journey into uncharted solar territory. (ANS thanks

<p><span style="font-family:"Segoe UI",sans-serif">+ NASA and Boeing are working together to prepare the CST-100 Starliner spacecraft for its next crewed flight, which is expected in late 2025 or early 2026. This follows the spacecraft’s first crewed mission,
which experienced a propulsion system failure that extended an eight-day mission to a nine-month stay for astronauts Butch Wilmore and Suni Williams, who later returned via SpaceX's Dragon capsule. In response, teams are conducting extensive testing and analysis,
including propulsion system evaluations at White Sands Test Facility to address overheating issues and helium leaks. Over 70% of the anomalies from the previous mission have been resolved, but major propulsion issues remain under review into 2025. Boeing’s
ongoing work on Starliner, which has cost over $2 billion, is part of NASA’s broader strategy to maintain flexible and safe access to space through commercial partnerships. If testing proceeds as planned, Starliner’s next mission could support either crew
or cargo transport to the International Space Station. (ANS thanks <a href="https://www.reuters.com/">
