SpaceX Launches Hamsats on Rideshare Mission

A Falcon 9 rocket carrying 131 different payloads lifted off on the company’s Transporter 12 mission from Vandenberg Space Force Base on January 14 at 19:09z. Included among the payloads were the amateur radio satellites HADES-R, operated by AMSAT-EA in Spain, and PARUS-T1, constructed by National Formosa University of Taiwan, among others.

With so many payloads aboard, not all of the satellites will be released at once. Rather, releases will be spaced over a period of time. At this writing, there is no word yet on the successful deployment of HADES-R. Further, the satellite will undergo several weeks of commissioning before the FM repeater is opened for use.

HADES-R has a downlink frequency, coordinated by the International Amateur Radio Union (IARU) of 436.888 MHz. While FM voice is the primary mission, the downlink may sometimes include FSK data up to 1200 bps, APRS up to 1200 bps, FSK telemetry and experimental data up to 1600 bps or CW. The uplink will be 145.925 MHz, Modes: FM voice (without subtone) and FSK 200 bps, AFSK, AX.25, APRS 1200 / 2400 bps.

Also launched on Transporter 12 was PARUS-T1, a 3U CubeSat dedicated to receiving APRS signals on three major global frequencies: 144.640 MHz, 144.390 MHz, and 144.800 MHz. The satellite will record the Received Signal Strength Indicator (RSSI) data for each received APRS packet and utilize a Global Navigation Satellite System (GNSS) receiver to determine the CubeSat’s orbit location during each signal reception. The received APRS data, RSSI values, and corresponding location data will be stored in the On-Board Computer (OBC) memory for transmission to ground stations.

Students will also be extensively involved in mission data analysis and will gain hands-on experience in understanding ionospheric propagation and its impact on terrestrial and satellite radio communications. The beacon packets shall not be encrypted and made public to the community via websites. Community participation will be encouraged through online leaderboards for example SatNOGS network. Data format of PARUS-T1 health telemetry and payload raw data will also be published and welcome all amateurs to receive 436.850MHz for packet data of AX.25 protocol on 1200bps.

PARUS-T1 also has an APRS digipeater to provide global amateur activities at the same frequency of ISS APRS channel 145.825 MHz.

A list of amateur radio payloads launched on the rideshare appears below:

Thirty-seven of the 131 payloads going up today belong to San Francisco company Planet, which operates three constellations of Earth-observing satellites. Thirty-six of the 37 Planet craft are “SuperDove” cubesats, shoebox-sized craft that collect images with a resolution of about 10 feet (3 meters) per pixel. The other one is Pelican-2, whose resolution is about 7.5 times sharper than that.

SpaceX has launched a total of 13 rideshare missions to date — the 11 Transporter flights and two in a different program known as Bandwagon. Together, these missions have lofted about 1,100 payloads for more than 130 different customers, according to the Transporter 12 description.

Two Private Moon Landers Have Launched at Once

A space twofer took place early Wednesday morning — two lunar missions for the price of one rocket launch.

A SpaceX Falcon 9 lifted off from the NASA’s Kennedy Space Center in Florida at 1:11 a.m. Eastern time, carrying the Blue Ghost lander built by Firefly Aerospace of Austin, Texas, and the Resilience lander from Ispace of Japan.

Why did two moon landers share one rocket? That was the result of fortuitous scheduling by SpaceX and not something that was planned by Firefly or Ispace.

Firefly had purchased a Falcon 9 launch to send its Blue Ghost lander to the moon. At the same time, Ispace, to save on the costs for the mission, had asked SpaceX for a rideshare, that is, hitching a ride as a secondary payload on a rocket launch that was going roughly in the right direction to get its Resilience lander to the moon. That turned out to be Blue Ghost’s trip.

“It was a no-brainer to put them together,” Julianna Scheiman, the director for NASA science missions at SpaceX, said during a news conference on Tuesday.

After the Falcon 9 rocket reached orbit, the second stage fired again for a minute so it could deploy Blue Ghost in an elliptical orbit around Earth, about an hour after launch. The rocket stage fired once more, for just a second, to adjust the orbit for the deployment of Resilience, about 1.5 hours after launch.

On Wednesday morning, Firefly and Ispace announced that their spacecraft successfully turned on, established communications with ground stations on Earth and were operating as expected.

According to AMSAT-DL, the German amateur satellite organization, the Firefly_Space Blue Ghost Mission includes the Lunar GNSS Receiver Experiment (LuGRE) with the goal of demonstrating GNSS-based positioning, navigation, and timing at the Moon. LuGRE will build on the legacy of prior missions in the Space Service Volume (SSV) including the initial experiments by AMSAT on OSCAR-40 (P3-D) satellite and others.

Blue Origin New Glenn Reaches Orbit on Its First Launch

Blue Origin entered into the history books in the predawn hours of Thursday, January 16. The company, founded by Jeff Bezos, became the first to successfully reach orbit on their first launch with a new orbital-class rocket in the new era of commercial spaceflight that dawned in the last two decades.

After dealing with an unplanned hold to chill its engines and a wayward boat entering the keep out zone, the New Glenn rocket, standing as tall as a 32-story building, lumbered off the pad under the power of 3.9 million pounds of thrust.

The seven BE-4 engines on the first stage booster roared to life at 2:03 a.m. EST (07:03 UTC) shining a brilliant orange that turned to blue as the liquified natural gas (LNG) fueled rocket began its journey from pad 36 at Cape Canaveral Space Force Station.

Blue Origin dealt with multiple weather-related delays to get to launch day and even during the countdown, faced uncertain skies that threatened to potentially delay the mission yet again.

It also ran into technical issues on its way to launch. Blue Origin said an issue that prevented Monday’s launch was “ice forming in a purge line on an auxiliary power unit that powers some of [New Glenn’s] hydraulic systems.” Teams worked to clear that issue during the three-hour window, but weren’t able to do so in time.

One of the goals of the NG-1 mission was to attempt to land the first stage booster, named ‘So You’re Telling Me There’s a Chance,’ on Blue Origin’s landing vessel, named ‘Jacklyn,’ which was positioned out in the Atlantic Ocean.

Ultimately, it was determined that the touchdown on the 380-foot-long (116 m) landing vessel, named ‘Jacklyn,’ was unsuccessful. That said, going into the launch, Blue Origin said repeatedly that landing the booster was an aspirational goal and not their main objective.

SpaceX Success & Failure in Starship Flight 7

SpaceX’s seventh flight of its Starship rocket was a combination of great success and catastrophic loss, with a catch of its Super Heavy booster at the launch tower and the failure of the Starship upper stage as it climbed to space.

Beginning around seven minutes and 40 seconds into the flight, SpaceX’s on-screen telemetry data began to show one Raptor engine after another turn off on the Ship until the telemetry froze at eight minutes and 27 seconds.

A still image taken from video of what is reportedly the remnants of SpaceX’s Starship upper stage as seen from the vantage point of the Turks and Caicos Islands. [Image: Alex Davenport and Spaceflight Now.]

The launch began nominally, with the more than 400-foot-tall rocket lumbering off of the pad at 22:37 UTC on Thursday, Jan. 16. The mission featured the first flight of the Block 2 variant of the upper stage.

The 33 Raptor engines on the booster powered it down range as expected and beginning about two minutes and 30 seconds into the mission, most of them cut off and the six Raptor engines on the Ship sprang to life to begin carrying it towards space.

The booster performed a flip maneuver and another burn to put it on a course towards the launch tower. The Super Heavy booster, B14, performed a final landing burn about 6 minutes and 30 seconds after liftoff and before seven minutes were up, it was caught by the tower.

Three U.S. Schools Moved Forward in ARISS Selection Process

Amateur Radio on the International Space Station (ARISS) is pleased to announce the U.S. schools/host organizations newly selected for 2025 ARISS contacts. A total of three of the submitted proposals during the recent proposal window have been accepted to move forward in the processes of planning to host a scheduled amateur radio contact with crew on the ISS. The primary goal of the ARISS program is to engage young people in Science, Technology, Engineering, Arts and Math (STEAM) activities and raise their awareness of space communications, radio communications, space exploration, and related areas of study and career possibilities.

The ARISS program anticipates that NASA will be able to provide scheduling opportunities for the 3 US host organizations during the July – December 2025 time period. They are now at work starting to implement their 4–6-month education plan which was outlined in their proposal. These STEAM based educational activities help prepare students for their contact as well as create an on-going exploration and interest in aerospace and amateur radio topics. They are also completing an acceptable equipment plan that demonstrates their ability to execute the ham radio contact. Once their equipment plan is approved by ARISS, the final selected schools/organizations will be scheduled as their availability and flexibility match up with the scheduling opportunities offered by NASA.

The schools and host organizations are:

  • Paterson P-Tech High School, Paterson, NJ
  • Pinecrest Academy, Cumming, GA
  • Terre Haute Children’s Museum, Terre Haute, IN

[ANS thanks ARISS for the above information]


New ARISS Proposal Window is Now Open

The Amateur Radio on the International Space Station (ARISS) Program is seeking formal and informal education institutions and organizations, individually or working together, to host an Amateur Radio contact with a crew member on board the ISS. ARISS anticipates that the contact would be held between July 1, 2025 and December 31, 2025. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan.

The deadline to submit a proposal is February 28, 2025. Proposal information and more details such as expectations, proposal guidelines and the proposal form can be found at www.ariss.org. An ARISS Introductory Webinar session will be held on January 22 at 8 p.m. EST. The Zoom link to sign up is: https://us06web.zoom.us/meeting/register/kznKuyHCRyKi8_j00JBd_g

The Opportunity

Crew members aboard the International Space Station will participate in scheduled Amateur Radio contacts. These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session.

An ARISS contact is a voice-only communication opportunity via Amateur Radio between astronauts and cosmonauts aboard the space station and classrooms and communities. ARISS contacts afford education audiences the opportunity to learn firsthand from astronauts what it is like to live and work in space and to learn about space research conducted on the ISS. Students also will have an opportunity to learn about satellite communication, wireless technology, and radio science. Because of the nature of human spaceflight and the complexity of scheduling activities aboard the ISS, organizations must demonstrate flexibility to accommodate changes in dates and times of the radio contact.

Amateur Radio organizations around the world with the support of NASA and space agencies in Canada, Japan, Europe and Russia present educational organizations with this opportunity. The ham radio organizations’ volunteer efforts provide the equipment and operational support to enable communication between crew on the ISS and students around the world using Amateur Radio.

Satellite Shorts From All Over

+ NASA astronaut Suni Williams, KD5PLB, one of the two astronauts stuck on the International Space Station by the Boeing Starliner failure, ventured outside for a spacewalk on Thursday, Jan. 16, for the first time since arriving on board seven months ago. Williams – an experienced astronaut who has conducted many spacewalks during previous stays aboard the ISS – teamed up with astronaut Nick Hague, KG5TMV, on Thursday to perform maintenance on the craft. (ANS thanks BBC.com for the above information.)

+ SpaceX maintained its rapid pace of launching an orbital mission on average every two days with its Falcon 9 flight from Cape Canaveral Space Force Station on Friday, Jan. 10. The Falcon 9 first stage booster for this mission, tail number B1067 in the SpaceX fleet, made a record-setting 25th launch and landing. (ANS thanks Spaceflight Now for the above information.)

+ After some delay due to drift issues, the two spacecraft from the Indian Space Research Organization’s (ISRO — India’s national space agency) SpaDex mission successfully docked with one another. On Thursday morning, Jan. 16, the space agency announced that it had made history by becoming only the fourth country in the world with such technology after United States, Russia and China. The booster for those satellites, still in orbit, carries the BGS ARPIT amateur radio experiment (see ANS 012 from last week.) (ANS thanks The Orbital Index and BBC.com for the above information.)

India Launches SpaDeX Satellites with Amateur Radio Experiment

India has launched the SpaDeX mission, designed to perform the country’s first autonomous docking experiment in space. A Polar Satellite Launch Vehicle (PSLV-C60) carried two SpaDeX satellites into orbit from the Satish Dhawan Space Centre in Sriharikota, India on December 30, 2024, at 11:30 a.m. EST (1630 UTC). The Indian Space Research Organisation (ISRO) sees this mission as a step toward supporting future Moon missions and building a space station.

The Space Docking Experiment (SpaDeX) consists of two 220-kilogram (485 pound) satellites, the Target and Chaser, which will test rendezvous and docking procedures. ISRO Chairman S. Somanath confirmed the satellites were placed in the correct orbit after launch. The first docking attempt is expected to occur in the next several days. The mission will assess the transfer of power between the docked spacecraft and evaluate dual-spacecraft control capabilities.

In addition to the docking experiment, the mission includes the POEM-4 (PS4-Orbital Experimental Module), which carries 24 payloads. These include a robotic arm demonstration and a debris capture manipulator. The robotic arm will test mobility for tasks in orbit, while the debris capture manipulator will attempt to retrieve tethered objects in an effort to address space debris.

One of the payloads aboard POEM-4 is the BGS ARPIT, an amateur radio project developed by the SJC Institute of Technology, the Upagrah Amateur Radio Club (VU2URC), and AMSAT-India to support educational activities and celebrate India’s 75th year of independence. This payload can transmit images via Slow Scan Television (SSTV), audio messages, and telemetry data on 145.870 MHz, and it also functions as an APRS digipeater on 145.825 MHz. Approved for IARU frequency coordination on December 22, 2024, BGS ARPIT completed its first SSTV transmission period on January 10th, with more trial periods sure to come soon.

Watch for BGS ARPIT SSTV announcements from @nitin_vu2jek on X. [Credit: SJC Institute of Technology]
The autonomous docking technology tested in SpaDeX is crucial for ISRO’s planned Chandrayaan-4 lunar mission, which aims to return samples from the Moon’s south pole. Docking capabilities will enable the transfer of samples to a return capsule in lunar orbit. This technology is also essential for the assembly and operation of the Bharatiya Antariksh Station, India’s planned space station.

The SpaDeX mission includes payloads developed by ISRO and collaborators from universities and startups. The experiments focus on areas like satellite servicing, space debris management, and educational outreach. The mission serves as a platform to advance technologies needed for India’s space exploration goals.

Parker Solar Probe Achieves Closest-Ever Approach to the Sun

NASA’s Parker Solar Probe reached a significant milestone on December 24, 2024, by coming within 3.8 million miles of the sun’s surface—the closest a human-made object has ever traveled toward a star. The spacecraft confirmed its survival through a signal received at the Johns Hopkins Applied Physics Laboratory (APL) on December 26. This marks another step forward in the mission’s effort to study the sun and its influence on the solar system. The probe, traveling at 430,000 miles per hour (692,000 kilometers per hour), continues to push the limits of solar exploration.

The mission allows the spacecraft to gather data from regions of the sun that were previously out of reach. Nicky Fox, associate administrator for NASA’s Science Mission Directorate, said, “By studying the sun up close, we can better understand its impacts throughout our solar system, including on the technology we use daily on Earth, as well as learn about the workings of stars across the universe.” This close approach opens the door for new measurements that could refine knowledge about solar wind, coronal heating, and other fundamental processes.

Launched in 2018, the Parker Solar Probe used seven Venus flybys to adjust its orbit and approach the sun. Its current orbit brings it near the sun every three months. A carbon foam heat shield, designed to withstand temperatures up to 2,600°F (1430°C), protects the spacecraft’s instruments, which remain at a stable temperature. During its latest encounter, the shield endured temperatures of 1,800°F (980°C), demonstrating the durability of its design and construction.

The spacecraft has already provided valuable data about solar phenomena. It has observed magnetic field structures called switchbacks, which help explain plasma heating and acceleration. Adam Szabo, mission scientist at NASA’s Goddard Space Flight Center, noted, “This close approach will give us more data to understand how the solar wind is accelerated closer in.” Measurements from within the solar corona offer new perspectives on how energy and particles move through this region.

Johns Hopkins APL confirmed that the Parker Solar Probe survived its close approach to the sun. [Credit: NASA/Johns Hopkins APL]
The Parker Solar Probe has also contributed to studies of Venus, detecting thermal emissions from its surface and capturing images of its orbital dust ring. These observations highlight the spacecraft’s ability to gather insights beyond its primary mission. Data from the recent solar pass will soon be transmitted to Earth, providing additional information for researchers.

Future solar passes are scheduled for March 22 and June 19, 2025. Ralph Semmel, John Hopkins Applied Physics Laboratory Director, emphasized the team’s efforts, stating, “Their incredible technological breakthroughs enabled this amazing mission, and they have delivered critical new insights that are revolutionizing our understanding of heliophysics and space weather.” As part of NASA’s Living With a Star program, the Parker Solar Probe continues to investigate the relationship between the sun and the Earth, providing valuable knowledge for science and society.

3D-Printed Helicone Antenna Tested for L-Band Weather Satellites

Gabe Emerson, KL1FI, the creator behind the YouTube channel saveitforparts has unveiled a new video highlighting a 3D-printable helical antenna for receiving weather data from polar-orbiting L-band satellites such as NOAA and Meteor. Designed by a user named t0nito, the 1.7 GHz HRPT Helicone Antenna design is freely available on Thingiverse. Its compact size, straightforward assembly, and effective performance have the potential to make it a hit among amateur radio and satellite enthusiasts. The manual, instructions, and 3D printer files can be accessed at https://www.thingiverse.com/thing:6436342.

The video begins with the challenges encountered during the printing process. Early attempts at creating the antenna’s helical scaffold were plagued by warping issues in the support legs, resulting in several failed prints. To address this, the original 3D model was modified to include additional center supports, ensuring a stable print. Once the printing phase was complete, the assembly process involved wrapping wire around a two-inch pipe, crafting a reflector from metal window screen, and piecing everything together.

Gabe gives build suggestions for the 1.7 GHz Helicone antenna after completing the initial antenna assembly. [Credit: saveitforparts]
Testing the completed antenna proved its effectiveness. Using an RTL-SDR receiver and the SatDump software, Gabe successfully received data from the NOAA-18 HRPT satellite. By manually tracking the satellite, clear and detailed weather images, including nighttime thermal and infrared captures, were obtained, showcasing the antenna’s capability for high-quality data reception.

Designed with simplicity in mind, the Helicone antenna features a Right-Handed Circular Polarization (RHCP) configuration. Instead of relying on screws, the assembly process used hot glue and materials such as copper wire and sheet metal were sourced from everyday household items. These choices highlight its accessibility and affordability for hobbyists of all experience levels.

A performance comparison with an existing motorized tracking antenna revealed that the Helicone delivered comparable signal strength and image quality. While hand-tracking limited its functionality, its portability and ease of use were standout features. The lightweight design and straightforward assembly make it an ideal choice for amateur satellite enthusiasts looking for a practical and cost-effective solution.

Gabe concludes with praise for the antenna’s design and a call to action for viewers to try building one themselves. Future enhancements, such as integrating the Helicone with a motorized tracking system, are already being considered. For now, this detailed guide offers an excellent starting point for satellite hobbyists eager to explore affordable and efficient ways to receive weather data from orbiting satellites. The video titled “This 3D-Printed Satellite Antenna Is Fantastic!” can be found on the saveitforparts YouTube channel at https://youtu.be/PFQ6UKulxSo.

Cold War Mystery: Why Did Jimmy Carter Save the Space Shuttle?

The Space Shuttle program, an enduring symbol of American ingenuity, came perilously close to cancellation in the late 1970s. With the recent passing of Jimmy Carter at age 100, a fascinating story has resurfaced: how the 39th president, despite his well-known skepticism toward manned spaceflight, played a critical role in rescuing the program. This surprising twist in Cold War history highlights Carter’s pragmatism and the complex interplay between space exploration and geopolitics during his presidency.

This story first emerged during an interview with Chris Kraft, the former NASA Johnson Space Center director and a key architect of the Apollo program. Kraft recounted a critical 1978 meeting at NASA’s Houston headquarters, where dire financial constraints threatened the shuttle’s future. By then, the program was years behind schedule and hundreds of millions over budget. Faced with insufficient funding, NASA leaders considered two bleak options: securing a massive funding boost or relegating the shuttle to a mere research vehicle, incapable of fulfilling its ambitious mission to deliver payloads into orbit.

NASA Administrator Robert Frosch took the crisis to Washington, presenting President Carter with a stark ultimatum. Carter, known for his ambivalence toward manned spaceflight, surprised everyone by asking, “How much do you need?” According to Kraft, Carter’s decision was influenced by recent discussions with Soviet leader Leonid Brezhnev during Strategic Arms Limitation Talks (SALT). Carter reportedly highlighted the shuttle’s capability to verify Soviet compliance with arms agreements, a claim that underscored its national security value. While some details of this account remain disputed, Carter’s administration approved supplemental funding in 1979 and 1980, effectively saving the shuttle program.

Carter’s support for the shuttle is striking given his prior skepticism about its purpose. Early in his presidency, Carter dismissed the shuttle as a “contrivance to keep NASA alive.” His vice president, Walter Mondale, had also labeled the program a “senseless extravaganza.” Yet, by the late 1970s, escalating Cold War tensions reframed the shuttle’s significance. A key memo from the National Security Council emphasized the shuttle’s strategic value, arguing that canceling the program would undermine national pride and technological leadership.

While some NASA officials, including Shuttle Program Manager Robert Thompson, downplayed the risk of cancellation, the financial reality was grim. Development of critical components, such as the shuttle’s main engines and thermal protection tiles, was years behind schedule. Without Carter’s intervention, the shuttle might never have achieved its iconic role, flying 135 missions over three decades and laying the groundwork for the International Space Station.

In later reflections, Carter acknowledged his lack of enthusiasm for human space exploration but defended his decision to fund the shuttle. “I didn’t want to waste the money already invested,” he explained, noting that he discussed the shuttle’s peaceful intentions with Brezhnev during SALT II negotiations. While Carter’s motivations may have been rooted in pragmatism and diplomacy, his actions ensured the shuttle’s place in history. Despite his mixed legacy on space policy, Carter’s pivotal role in salvaging the shuttle underscores his capacity to recognize the broader implications of technological leadership during a turbulent era.

Changes to AMSAT-NA TLE Distribution for January 10, 2024

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 this week “POEM 4 (BGS ARPIT)” was added where “POEM 4” is the name that appears in the USSF 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:

POEM 4 (BGS ARPIT) NORAD Cat ID 46495

The following satellites have been removed from this week’s AMSAT TLE distribution:

PRISM (HITOMI) NORAD Cat ID 33493 Likely defunct
YUBELEINY 2 (RS-40) NORAD Cat ID 33735 Likely defunct
CHUBUSAT-2 NORAD Cat ID 41338 Likely defunct
CHUBUSAT-3 NORAD Cat ID 41339 Likely defunct
PRATHAM NORAD Cat ID 41783 Likely defunct
D-SAT NORAD Cat ID 42794 Likely defunct
RANGE-B NORAD Cat ID 43772 Likely defunct
CySat-1 NORAD Cat ID 61501 Decayed from orbit on or about 09 January 2025
MRC-100 NORAD Cat ID 56993 Decayed from orbit on or about 05 January 2025

Satellite Shorts From All Over

+ Eutelsat’s OneWeb internet constellation experienced a 48-hour outage starting on December 31, 2024, due to a software glitch likely caused by failing to account for the leap year. The issue disrupted internet services but was resolved once the root cause, a ground segment software problem, was identified and addressed. Eutelsat operates over 630 satellites and has been building the OneWeb constellation since 2020 to provide global high-speed internet, targeting business clients rather than direct consumers. The company faced challenges in launching its satellites due to strained relations with Roscosmos following the Russian invasion of Ukraine, forcing it to rely on SpaceX and India for launches. Despite completing its constellation in 2023, regulatory delays in countries like India and Turkey have prevented global broadband coverage, leaving services available only in limited regions. Eutelsat is now planning to update its constellation with 100 new satellites by Airbus, aiming for improved reliability and full global service rollout by spring 2025. (ANS thanks Gizmodo for the above information)

+ Florida’s Space Coast set a record with 93 launches in 2024, surpassing the previous year’s 74, thanks to innovations from Space Launch Delta 45 and private sector collaboration. Brig. Gen. Kristin Panzenhagen credited advancements like automation, modernized infrastructure, and streamlined processes for the milestone. SpaceX dominated with 88 launches from Florida and completed 134 missions globally, including government, commercial, and test flights. The Space Force introduced initiatives like the “One Falcon” program to support SpaceX’s rapid launch cadence, unifying personnel across ranges to enhance efficiency. Although only four launches directly supported national security, innovations in commercial space strengthen resilience and responsiveness for military missions, exemplified by the Rapid Response Trailblazer mission. With Blue Origin’s New Glenn and ULA’s Vulcan Centaur preparing for national security roles, competition is poised to grow, diversifying capabilities and bolstering launch options. (ANS thanks SpaceNews for the above information)

+ SpaceX’s next-generation Starship, Version 2 or Block 2, is set to launch on its seventh test flight from Starbase, Texas, as early as Monday, January 13, 2025, with the launch window opening at 5:00 p.m. EST (4:00 p.m. CST; 2200 UTC). This iteration, taller and more advanced than its predecessors, introduces numerous upgrades, including smaller, repositioned flaps for better heat protection, an enhanced propulsion system, and improved avionics for extended missions. For the first time, SpaceX will test Starship’s payload deployment mechanism, releasing mock Starlink satellites on a suborbital trajectory and conducting reentry experiments to refine the vehicle’s heat shield and reuse capabilities. The Super Heavy booster, equipped with additional protections and sensor enhancements, aims to achieve another tower catch, a feat last accomplished in October. The mission also marks progress toward full reusability, with one of the booster’s engines recovered and reused from a previous flight. These advancements, combined with a focus on orbital refueling and vehicle endurance, lay the groundwork for Starship’s future goals, including lunar landings under NASA’s Artemis program and beyond. (ANS thanks Ars Technica for the above information)

+ Firefly Aerospace’s Blue Ghost Mission 1, named “Ghost Riders in the Sky,” is set to launch in mid-January aboard a SpaceX Falcon 9 rocket, marking the company’s first lunar mission. The lander, recently integrated at NASA’s Kennedy Space Center, will carry 10 NASA payloads and technology demonstrations as part of NASA’s Commercial Lunar Payload Services (CLPS) program. These payloads will test conditions between Earth and the moon, investigate lunar geology, and demonstrate innovative technologies like radiation-resistant hardware and lunar GPS. The 60-day mission includes 25 days in Earth orbit, a four-day translunar injection, 16 days in lunar orbit, and two weeks of operations on the moon’s surface. During its time on the moon, Blue Ghost will collect critical data and images, including capturing a solar eclipse and documenting the phenomenon of lunar dust levitation, last observed during Apollo 17. The mission will provide valuable insights to support NASA’s goal of a sustainable human presence on the moon through Artemis while also showcasing the technical capabilities of private industry. Firefly CEO Jason Kim emphasized the mission as a tribute to Apollo’s legacy and a pivotal step forward in advancing lunar exploration. (ANS thanks Space.com for the above information)

Taiwan’s PARUS-T1A Launch Failed

Radio Amateurs around the world were anticipating a new FM repeater in space as a Christmas present this year, but it seems they will find only coal in their stockings. The rocket carrying the PARUS T1A satellite failed to reach orbit.

Space One, a Japanese space startup, said its second attempt to launch a rocket carrying satellites into orbit had been aborted minutes after liftoff Wednesday and destroyed itself, nine months after the company’s first launch attempt ended in an explosion.

Space One’s Kairos No. 2 rocket lifted off from a coastal site in the mountainous prefecture of Wakayama in central Japan. The company said it had aborted the flight after concluding that it was unlikely to complete its mission.

“We are very sorry that we could not achieve as far as a final stage of the mission,” Space One President Masakazu Toyoda told a news conference Wednesday. “We don’t consider this a failure because we are getting valuable data that will help our pursuit toward a next challenge.”

He said he hoped to find the cause to address the problems as soon as possible to achieve a success next time.

Company executive and space engineer Mamoru Endo said the abnormality in the first stage engine nozzle or its control system is likely to have caused an unstable flight of the rocket, which started spiraling in midflight and eventually destroyed itself about three minutes after liftoff, using its autonomous safety mechanism.

The Kairos No. 2 rocket was carrying five small satellites, including one from the Taiwanese space agency and several from Japanese startups. The Taiwanese satellite was PARUS-T1A a 3U CubeSat that featured an FM crossband repeater, as well as an APRS digipeater to provide global amateur activities at the same frequency of ISS APRS channel 145.825MHz.

A second Taiwanese amateur satellite, PARUS-T1, carrying an APRS store-and-forward system, is still scheduled for launch next month on a SpaceX mission. Both satellites were constructed by students at National Formosa University.

Space One said it had fixed the cause of the debut flight failure, which stemmed from a miscalculation of the rocket’s first-stage propulsion.

Japan hopes the company can pave the way for a domestic space industry that competes with the United States.

NASA Astronauts Face More Time In Space With Return Delayed

NASA announced on Tuesday the latest delay in the homecoming for Butch Wilmore and Suni Williams, KD5PLB. Their space mission was extended again. That means they won’t be back on Earth until spring, 10 months after rocketing into orbit on Boeing’s Starliner capsule.

The two test pilots planned on being away just a week or so when they blasted off June 5 on Boeing’s first astronaut flight to the International Space Station. Their mission grew from eight days to eight months after NASA decided to send the company’s problem-plagued Starliner capsule back empty in September.

Now the pair won’t return until the end of March or even April because of a delay in launching their replacements, according to NASA.

NASA’s next crew of four was supposed to launch in February, followed by Wilmore’s and Williams’ return home by the end of that month alongside two other astronauts. But SpaceX needs more time to prepare the brand new capsule for liftoff. That launch is now scheduled for no earlier than late March.

Last month, news articles suggesting that Ms. Williams was experiencing health problems during her unplanned extended stay in orbit set off widespread rumors on social media. NASA’s medical chief, Dr. James Polk, assured the public on November 14 that Williams is healthy and not suffering from any medical problems.

“I think there’s some rumors around outside there that I’m losing weight and stuff,” Williams said in an interview on November 12. “No, I’m actually right at the same amount. Things shift around quite a bit, you know? ”

Not only is she healthy, according to her and NASA, but they made Williams commander of Expedition 72 crew. As KD5PLB, she continues to be an active participant in ARISS contacts during her time aboard the ISS.

NASA Now Knows Why Its Mars Helicopter Crashed

Investigating an aircraft crash is no simple task here on Earth. Imagine how much more difficult it would be to diagnose a helicopter accident that took place 69 million miles away with none of the usual data present to help. NASA had to do just that after its Ingenuity Mars Helicopter suffered an accident on Jan. 18, 2024, that has since left it grounded in a crater on Mars. And now, after months of collecting data, the space agency may have finally figured out what happened.

On April 19, 2021, the NASA Ingenuity Mars Helicopter made history by lifting off the Jezero Crater’s floor and becoming the first aircraft to fly on a celestial entity other than Earth. The helicopter was supposed to fly only five experimental flights over 30 days to demonstrate that flight on Mars was possible. But it exceeded all expectations, conducting 72 flights over three years, setting all sorts of altitude records in the process, ending with that early 2024 accident.

The final moments of the helicopter’s flight were more or less a mystery at first. Ingenuity lifted off like it had 71 times before. Then camera footage showed that it began initiating descent after just 19 seconds of flight. By the time 32 seconds had elapsed, the helicopter was on the Martian surface again and had halted communications. Six days later, the helicopter beamed back images that showed it had sustained severe rotor-blade damage and would no longer be able to fly.

Now, NASA believes that the navigation system was ultimately to blame. The navigation system used the helicopter’s downward-facing camera to track visual features on the ground. During this final flight, the helicopter was flying over a portion of the Jezero Crater that is known for textured, featureless sand ripples. The navigation system was thus unable to find any suitable ground features to track for a landing.

From there, several things went wrong. NASA says that the helicopter made hard contact with a sand-ripple slope, causing it to pitch and roll. The sudden change in altitude was too much for the rotor blades, and four of them broke off at their weakest points. This caused the rotor system to vibrate excessively, which ripped one of the blades clean off. Finally, the incident generated an excessive power draw that caused communications to fail.

“When running an accident investigation from 100 million miles away, you don’t have any black boxes or eye witnesses,” said Håvard Grip, Ingenuity’s first pilot and research technologist at JPL Robotics. “While multiple scenarios are viable with the available data, we have one we believe is most likely: Lack of surface texture gave the navigation system too little information to work with.”

Nobody expected Ingenuity to last as long as it did. Its flights gave researchers excellent aerial views of our red neighbor. Even now, as it lies in the sands of the Jezero Crater, Ingenuity can no longer fly but still beams back weather and avionics data to NASA. The avionics data along with the flight data from Ingenuity’s 72 flights — combined with Ingenuity’s incredible longevity — are helping NASA develop smaller, lighter avionics for future aircraft on Mars.

“Because Ingenuity was designed to be affordable while demanding huge amounts of computer power, we became the first mission to fly commercial off-the-shelf cellphone processors in deep space,” said Ingenuity project manager Teddy Tzanetos. “We’re now approaching four years of continuous operations, suggesting that not everything needs to be bigger, heavier and radiation-hardened to work in the harsh Martian environment.”

Tzanetos and his team are already working on another Mars helicopter. It’s approximately 20 times heavier than the Ingenuity and is being designed to carry several pounds of science equipment while autonomously exploring remote locations on Mars.

Changes to AMSAT-NA TLE Distribution for Dec. 20

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/.

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

Satellite Shorts From All Over

+ AO-73 (a.k.a. FUNcube 1) has been switched from autonomous mode to continuous transponder mode for the holiday period. This means that the transponder is available for use 24/7. AO-73 is anticipated to revert to autonomous mode sometime after January 5, 2025. In autonomous mode, the transponder is only available when the satellite is in eclipse. (ANS thanks AMSAT-UK for the above information.)

+ Two Chinese astronauts aboard their country’s orbiting space station spent nine hours working outside in the cold vacuum of space, the longest recorded spacewalk, the Chinese space administration has said. The astronauts on China’s Shenzhou-19 mission, Cai Xuzhe and Song Lingdong, finished their first “extravehicular activities” — spacewalking in popular parlance — this week, apparently nudging past the previous record of eight hours and 56 minutes set by two American astronauts in 2001, according to China’s Manned Space Agency. The feat was another sign of China’s ambitions to project its power and prestige in space. (ANS thanks The New York Times for the above information.)

+ The internet news site MSN recently published a feature on the history of amateur radio and astronauts in orbit, beginning with Owen Garriott, W5LFL, in 1983 and continuing to the present ARISS program. “How Amateur Radio Is Connecting Astronauts In Space With Kids On Earth” was written by Leonard David. See it at http://bit.ly/4gnfE3y (ANS thanks msn.com for the above information.)

+ The first Block 2 version of the giant SpaceX Starship, Ship 33, recently rolled out for testing and completed its first static fire test. It will be stacked on Booster 14 before it is targeted to complete the first flight of the Block 2 reusable upper stage in January. This upgraded Ship adds catch hardware and an additional ring, making it 1.8 m taller and now totaling 124.4 m (408 feet) when eventually stacked on top of Booster 14. The added height will allow it to pack 300 tons more propellant. (ANS thanks The Orbital Index for the above information.)
