AMSAT Seeks Volunteers to Assist with 2024 Hamvention AMSAT Booth

With less than six weeks until the 2024 Dayton Hamvention, scheduled for May 17th to May 19th in Xenia, Ohio, excitement mounts for the 72nd installment of this premier gathering for ham operators worldwide. In 2023, attendance surged to 33,861, surpassing both the previous year and pre-pandemic records, indicating growing enthusiasm. The 2024 event, anticipated to draw even larger crowds, will also host the ARRL National Convention.

AMSAT, a key exhibitor, will once again occupy a spacious 1,200 square foot area at Building 1’s north end, known as the Maxim building. This location, ideally situated for its ventilation and access to the outdoor satellite ground station, is perfect for showcasing AMSAT’s exhibits. The booth will feature various attractions, including engineering team members, CubeSatSim, Beginner’s Corner, Youth Initiative, merchandise sales, software demonstrations, and membership sign-ups. Notably, this year’s booth will spotlight the revamped AMSAT Ambassador program, offering opportunities for engagement.

AMSAT AO-109 (Fox-1E) Satellite Sets New Processor Uptime Record

AMSAT’s AO-109, also known as Fox-1E, has recently achieved a remarkable milestone. Launched in January 2021, this satellite operates with an 8 mW signal, best suited for CW and FT4 communications among amateur radio enthusiasts. Recent telemetry data from the Dwingeloo Radiotelescope in The Netherlands has revealed an impressive feat: AO-109 has set a new record for processor uptime. This information was gathered by Alan Biddle, WA4SCA, who has meticulously monitored telemetry reports on a daily basis and calculated the duration of each reset, allowing for precise correlation of telemetry frames with UTC time.

The Fox satellites are designed to undergo onboard computer resets triggered by factors like radiation exposure and low battery voltage. Time on these satellites is measured by counting resets plus the duration since the last reset. It is common for the Fox satellites to reset every few days or weeks, especially when passing over the South Atlantic Anomaly. However, the processor on AO-109 has been running continuously since September 2023, accumulating over 18 million seconds of uptime—far surpassing any other Fox satellite.

Launched on January 17, 2021, as part of the ELaNa 20 mission using a LauncherOne rocket operated by Virgin Orbit, AO-109 was carried aloft by a modified Boeing 747 named “Cosmic Girl” from the Mojave Air and Space Port in California, United States. After reaching an altitude of approximately 35,000 feet (11,000 meters), the rocket was released into space. This launch, conducted under NASA’s CubeSat Launch Initiative program, marked the beginning of the satellite’s mission to facilitate amateur radio communications and technology research.

AO-109 represents the fifth iteration of the “Fox” 1U amateur radio satellites series developed by AMSAT, featuring a 30KHz linear transponder radio. Upon becoming operational on July 20, 2021, AO-109 embarked on a mission to serve both amateur radio and technology research objectives. Among its key payloads is RadFXSat-2, a collaboration with Vanderbilt University, aimed at studying the effects of space radiation on specific SRAM types. Consistent with the Fox 1A design blueprint, Fox-1E is equipped with a 2-meter whip antenna and a 70 cm whip antenna.

With its anticipated re-entry into Earth’s atmosphere in the coming weeks, users are encouraged to make the most of AO-109 while it’s still operational. Current reports suggest the satellite’s altitude is around 300 km, which is lower than the ISS orbiting altitude of 370–460 km.

ESA Unveils Proba-3 Mission: Artificial Solar Eclipses on Demand

Next week, a celestial spectacle will unfold across North America as millions of people witness a total solar eclipse. Alongside eager spectators, solar physicists worldwide are gearing up for the event, drawn by the opportunity to study the Sun’s enigmatic corona, typically obscured by its intense luminosity. However, thanks to a innovative initiative by the European Space Agency (ESA), sustained examination of the solar corona will soon become feasible through the Proba-3 mission.

In Belgium last week, the European Space Agency revealed the spacecraft pair which constitute the Proba-3 mission. This initiative aims to generate orbital solar eclipses at will, providing researchers with extended periods to scrutinize the Sun’s ethereal corona. The mission comprises two spacecraft: the Occulter and the Coronagraph. Positioned approximately 150 meters apart, these spacecraft will align meticulously with the Sun, with the Occulter casting a shadow onto the Coronagraph, effectively blocking out the Sun’s glare and unveiling the corona.

Dietmar Pilz, ESA’s Director of Technology, Engineering, and Quality, explains, “The two spacecraft will act as if they are one enormous 150-meter-long instrument.” However, achieving such precision poses immense technical challenges. Even the slightest misalignment could disrupt the mission’s efficacy. Consequently, the development process, spearheaded by a consortium of ESA Member States led by Spain and Belgium, has been extensive.

The fundamental concept of generating artificial solar eclipses in orbit isn’t novel. Previous attempts, such as the Apollo-Soyuz Test Project in 1975, have explored similar endeavors. However, Proba-3 seeks to institutionalize this capability through precise formation flying, enabling up to six hours of continuous observation per orbit lasting 19 hours and 36 minutes.

Solar eclipses, a consequence of the fortunate alignment of the Sun and the Moon, unveil the solar corona — a region of profound scientific and practical significance. Significantly hotter than the Sun’s surface, the corona influences space weather, solar wind, and phenomena like coronal mass ejections, which can impact satellite operations and terrestrial communications networks.

Proba-3’s groundbreaking approach involves orchestrating the Occulter and Coronagraph to operate as a unified entity, thus minimizing diffraction effects and maximizing the observation of the corona. This collaboration, facilitated by advanced positioning technologies, promises to unveil the mysteries of the corona within the range of 3 to 1.1 solar radii from the Sun.

The mission’s autonomy is paramount, with precise formation flying orchestrated autonomously to minimize external perturbations. This autonomy enables the spacecraft to maintain precise alignment for optimal observation of the corona while passively drifting during the remainder of the orbit.

Beyond its scientific implications, the success of Proba-3 could herald a new era of space missions, facilitating endeavors like in-orbit satellite servicing and deploying larger-scale space infrastructure. Moreover, the mission’s instruments, like ASPIICS and the radiometer, hold promise for climate modeling and advancing our understanding of solar dynamics.

As the world awaits the North American total solar eclipse, members of Proba-3’s science team seize the opportunity to test mission hardware. Components like polarizing filter wheels and alternative LED technologies will undergo rigorous examination, further refining the mission’s capabilities.

Satellite Shorts From All Over

+ NASA will launch three scientific-sounding rockets into the moon’s shadow on April 8 during a partial solar eclipse across North America, coinciding with a total solar eclipse in certain areas. The project, named Atmospheric Perturbations Around The Eclipse Path (APEP), aims to investigate how the sudden drop in sunlight and temperature during the eclipse affects Earth’s upper atmosphere. Named after the serpent deity from ancient Egyptian mythology, APEP will involve rockets launched from Wallops Flight Facility in Virginia. These rockets, equipped with secondary instruments, will measure changes in electric and magnetic fields, density, and temperature as they penetrate the ionosphere during the eclipse. Understanding these perturbations in the ionosphere is crucial for predicting disturbances that impact satellite communications and ensuring the smooth operation of our communication-dependent world. (ANS thanks Jamie Carter, Senior Contributor, Forbes, for the above information)

+ The final launch of United Launch Alliance’s Delta Heavy IV rocket is scheduled for April 9, marking the end of a 64-year legacy for the Delta family. The highly successful career of the Delta Heavy IV comes to a close as it launches a classified payload, NROL-70, on behalf of the U.S. National Reconnaissance Office (NRO). The NRO, responsible for the country’s surveillance satellites, maintains secrecy about the specifics of its missions. This final launch aims to enhance the NRO’s capabilities in providing intelligence to national decision-makers and supporting global humanitarian efforts. United Launch Alliance plans to retire both the Delta IV Heavy and the Atlas V to pave the way for its new Vulcan Centaur rocket, with the Atlas V scheduled for missions until 2029. The era of the Delta family concludes amidst a transition towards more advanced launch technologies and capabilities. (ANS thanks Brett Tingley, Managing Editor, Space.com, for the above information)

+ Despite facing numerous challenges, including malfunctioning temperature sensors and unused battery cells, Japan’s SLIM Moon lander has defied expectations by surviving a second lunar night, despite being in a precarious position with its thrusters pointed upward and solar arrays facing away from the Sun. The Japan Aerospace Exploration Agency (JAXA) received a signal from the lander indicating it had restarted after hibernating to avoid freezing temperatures on the Moon’s surface. Initially forced to shut down due to insufficient electricity generation from its solar cells, SLIM has persisted against the odds, reviving itself twice since its landing on January 19. Although not designed to endure the Moon’s harsh conditions, the lander has continued to function, prompting uncertainty about JAXA’s future plans for the resilient spacecraft after it successfully achieved its primary mission goal of a precise lunar landing within a 328-foot radius. (ANS thanks Passant Rabie, Gizmodo, for the above information)

+ China’s Queqiao-2 satellite successfully launched from the Wenchang Space Launch Site on March 20th, reaching lunar orbit after a perilune braking maneuver near the Moon’s surface on March 24th. Positioned to relay communications for future lunar missions, including Chang’e-4 and Chang’e-6, Queqiao-2’s orbit will be adjusted to facilitate these missions and support China’s ambitious lunar exploration program. Accompanying experimental satellites, Tiandu-1 and -2, also entered lunar orbit, conducting tests in communication and navigation. Queqiao-2’s strategic orbit placement in the Moon’s maria region holds significance for China’s lunar exploration history, including past probe landings fifteen years ago on March 1, 2009. China’s lunar missions, aiming to scout resources and establish a lunar base, signify a substantial endeavor parallel to NASA’s Artemis Program, which plans to establish a sustained presence on the Moon with international collaboration.

AMSAT-DL Proposes Next Generation GEO/MEO Amateur Radio Payload

At the request of the IARU, the European Space Agency (ESA) is supporting an initiative to define a future amateur radio satellite payload in geostationary orbit. The implementation is to take place through collaborative cooperation between internal, industrial and amateur radio participants. This activity will consolidate the requirements of the amateur and commercial satellite industry, weigh up different payload options, address the future user segment, develop scenarios for the financing, procurement and operation of such a payload, and investigate possibilities for placement on geostationary platforms.

This past weekend, AMSAT-DL released their proposal. AMSAT-UK, along with the British Amateur Television Club, AMSAT-NA, and the UK Microwave Group previously made a separate proposal. AMSAT-DL’s proposal is written by the authors Kai Siebels, DH0SK and Matthias Bopp, DD1US. The proposal takes into account the technical requirements and needs of radio amateurs. Various aspects such as orbit, satellite and platform as well as payload are taken into account.

Among the possible orbits such as MEO, HEO and GEO, the GEO orbit has proven to be the most suitable due to the extensive experience with OSCAR-100. A good compromise for the orbit position would be at ~43 degrees West to also support Eastern European countries and most of North America.

A payload for amateur radio should allow the greatest possible scope for experiments on different bands. Six bands could be used for the uplink to enable experiments with different frequencies. The main uplink band is the 13 cm band, the main downlink band is the 3 cm band. All proposed band / NB transponder combinations can be implemented at the ground station with very reasonable effort.

A dedicated AMSAT (Amateur Radio) mission based on an ESA-supported Micro GEO provides opportunities for several additional experiments that support AMSAT’s education, science and development goals to inspire young people with amateur radio technology. Finally, such a mission could also provide an excellent platform for disaster/emergency communications directly via the GEO satellite transponders.

Micro GEO and QO-100

Micro GEO satellites are a new class of small geostationary communications satellites. They are around a tenth of the size of traditional geostationary satellites and typically measure just one cubic meter. This smaller size makes them significantly cheaper to manufacture and launch, allowing satellite operators to offer customized regional services or gap fillers that would not be financially feasible with large satellites.

The amateur radio payload “QO-100” on the Es’hail-2 geostationary satellite, is a groundbreaking platform for the amateur radio community as it represents the first geostationary payload for amateur radio. The exemplary collaboration between AMSAT-DL, QARS and commercial partners on this project to integrate amateur radio payloads into a commercial satellite is a sign of the ongoing cooperation between the amateur radio community and the commercial space industry. This synergy can open up new avenues for amateur radio projects in space. QO-100 serves as a bridge between traditional approaches and new possibilities, while remaining firmly rooted in the principles of amateur radio. Its presence in geostationary orbit is a triumph for the amateur radio community and a sign that amateur radio can continue to play an important role in the exploration and use of space.

SYNCART 2.0 on the Heinrich Hertz satellite

The Heinrich Hertz Satellite Mission (also known as H2Sat) is a national, geostationary communications and research satellite. It was planned by the Space Agency of the German Aerospace Center (DLR) on behalf of the BMWi as part of the German government’s space strategy and serves both independent payloads (“hosted payloads”) and the in-orbit verification (IOV) of technologies as well as for research purposes.

In July 2012, AMSAT-Germany (AMSAT-DL) proposed an amateur radio payload on the Heinrich Hertz satellite with the name “SYNCART 2.0”. This was a further development of the transponders of the P3-D AMSAT-OSCAR-40 satellite in the X and K amateur radio bands and a beacon in the 76 GHz band.

The objectives of the amateur radio payload were as follows:

  • Development of the geostationary orbit for the amateur radio service
  • Communication resource for emergency and disaster radio (with low-power, small, simple technology)
  • In-orbit verification of SDX technologies
  • Promoting the spread of microwave technology
  • Gaining new insights by studying propagation conditions in the 76 GHz band for satellite applications
  • Provision of a signal for the calibration of antennas, converters and receivers, in particular for radio astronomical applications
  • Stimulating the acquisition of scientific and technical education, especially among schoolchildren and young people, by providing a permanently available satellite resource, e.g. for use in teaching, research and education
  • Acquisition of concrete knowledge and experience with satellite technologies and corresponding research opportunities in order to provide the space industry with highly qualified specialists.

The concept aimed to make efficient and effective use of any remaining H2Sat capacity.

The Heinrich Hertz feasibility study was completed in 2010. Planning phase B was carried out from 2011 to 2013. In July 2012, AMSAT-DL submitted its proposal for an amateur radio payload. Unfortunately, important positions on the antenna deck and with the payloads were already occupied at this point. There was also an approach for a Ka/Ka relaying transponder, but its use would have been limited to two small spot beams to northern Germany and southern Germany. At the time, this did not seem justifiable to our members and the amateur radio community in terms of the cost/benefit ratio. After it became clear that an amateur radio payload on the Heinrich Hertz satellite in the proposed form was not feasible, the proposal was finally withdrawn in September 2012.

Miraculously, however, a new window opened just a few months later! Initial talks and contacts were held as early as December 2012, which ultimately led to an amateur radio payload on the Es’hail-2 satellite, also known as Qatar-OSCAR 100 or QO-100. Es’hail-2/QO-100 was launched aboard a SpaceX Falcon 9 rocket on November 15, 2018. This project is a joint initiative of the Qatar Satellite Company, the Qatar Amateur Radio Society and AMSAT-DL. The satellite was built by Mitsubishi Electric Corporation in Japan and is located in a geostationary orbit at 26° East.

AMSAT-DL’S ERMINAZ satellites have completed frequency coordination with the IARU.

The ERMINAZ mission is a syndicated multi-PocketQube mission with a total of 7 PQs under the leadership of AMSAT-Germany, which also holds the launch contract with RFA under DLR support. The project is in collaboration between AMSAT-DL, AMSAT-EA (Spain), ESERO-Germany (Bochum Observatory) and Libre Space Foundation (Greece). The mission is to promote, advance and develop knowledge about space and amateur radio. ERMINAZ-1U & ERMINAZ-1V will transmit telemetry, images, provide a digipeat/store/forward functionally to all radio amateurs worldwide. ERMINAZ-1U will operate in the UHF amateur satellite band, while ERMINAZ-1V will operate in the VHF amateur satellite band. Only non-proprietary, open source and documented protocols, accessible to radio amateurs, will be used. This includes CCSDS telemetry, CW beacon, SSDV images, digipeater, AX.25 und possibly other modes. Telemetry and sensor data from radiation sensor and triaxial accelerometer / gyroscope / magnetometer will allow any radio amateur to participate by extending his knowledge about space. In addition, a digipeater and store & forward function will allow licensed radio amateurs to use ERMINAZ-1U/1V as a relay to communicate with other radio amateurs worldwide. The mission will conduct several experiments with different types of modulations, bandwidths, data rates and framing schemes: GFSK with data rate from 9600 up to 19200 GFSK with data rate from 9600 up to 19200 bits/s GMSK with data rate from 9600 up to 19200 bits/s BPSK with data rate from 9600 up to 19200 bits/s QPSK data rate from 19200 up to 38400 bits/s Frames will using three different framing schemes configurable upon the mission requirements: CSDS (residual or suppressed carrier) or IEEE 802.15.4 (preamble, sync) or AX.25. Planning a launch by RFA-Rocket Factory Augsburg AG from SaxaVord Spaceport into a 500km polar orbit not earlier than August 2024 together with UNNE-1 (HADES-E) and MARIA-G (HADES-F) from AMSAT-EA and QUBIK 5 from LibreSpace.

Up and downlinks on 145.965 MHz (ERMINAZ-1V) and 435.775 MHz (ERMINAZ-1U) have been coordinated.

Satellite Shorts from All Over

+ Shields up! On October 19, 1989, a monstrous X13 class solar flare triggered a geomagnetic storm so strong that auroras lit up the skies worldwide the following day. Had you been flying around the Moon at that time, you would have absorbed a dose that would most likely kill you within a month or so. This is why the Orion spacecraft that is supposed to take humans on a Moon fly-by mission this year has a heavily shielded storm shelter for the crew. But shelters like that aren’t sufficient for a flight to Mars. To obtain protection comparable to what we enjoy on Earth would require hundreds of tons of material, and that’s simply not possible in orbit. The primary alternative—using active shields that deflect charged particles just like the Earth’s magnetic field does—was first proposed in the 1960s. Today, we’re finally close to making it work. Fascinating full article at https://bit.ly/3PANp67 (ANS thanks ARS Technica for the above information.)

+ Not an April Fool’s joke: The U.S. Army has conducted a series of experiments, beginning in 1904 and continuing into the 1970s, on using trees as shortwave antennas. “It would seem that living vegetation may play a more important part in electrical phenomena than has been generally supposed. If, as indicated… in these experiments, the earth surface is already generously provided with efficient antennas which we have but to utilize for communications.” For complete details on how to turn the oak in your yard into a radiator for the 60 meter band, there’s a 55-page scientific paper at https://apps.dtic.mil/sti/tr/pdf/AD0742230.pdf (ANS thanks The Orbital Index for the above information.)

+ I’ve been workin’ on the railroad: Northrop Grumman Corporation was selected this month by DARPA to further develop the concept of building a moon-based railroad network as part of the broader 10-year Lunar Architecture Capability Study. The envisioned lunar railroad network could transport humans, supplies and resources for commercial ventures across the lunar surface. (ANS thanks The Orbital Index for the above information.)

First SONATE 2 Images Received

First images were received this week from the SONATE 2 satellite. A low-resolution Slow-Scan TV (SSTV) image that had been pre-loaded onto the satellite prior to launch was received on March 8. The first wide field of view earth image from the onboard camera was received on March 11. Both images can be viewed at https://www.informatik.uni-wuerzburg.de/en/aerospaceinfo/staff/kayal/research-activities/sonate-2/

[12.03.2024 First wide field of view image from SONATE-2]

SONATE 2 was built by students and faculty in the Aerospace Information Technology program at at Würzburg University in Germany. It was launched on March 4 as part of the SpaceX Transporter 10 mission from Space Launch Complex 4E in Vandenberg SFB, Calif.

Using Doppler measurements, Nico Janssen, PAØDLO, has identified SONATE 2 as object 59112. The telemetry downlink frequency is 437.0254 MHz, just slightly above the published target frequency of 437.025 MHz. Telemetry is in 9k6 G3RUH GMSK AX.25 using a protocol that may be downloaded from https://www.informatik.uni-wuerzburg.de/fileadmin/1003-ifex/2024/SONATE-2_protocol_definition_for_radio_amateurs.xlsx

The SSTV downlink is at 145.880 MHz FM using the Martin M1 protocol. The satellite also carries an APRS digipeater for 145.825 MHz, but the digipeater is not yet active. A schedule for upcoming SSTV transmissions is published at https://www.informatik.uni-wuerzburg.de/aerospaceinfo/mitarbeiter/kayal/forschungsprojekte/sonate-2/information-for-radio-amateurs/

FUNcube Mode Change

The FUNcube team are pleased to announce that FUNcube 1 (aka AO-73) is out of Safe mode back in Eclipse mode as of March 11. “Eclipse mode” means that the transponder is normally operational only when the satellite is in eclipse, i.e. the solar panels are NOT being illuminated.

The nominal transponder frequencies are:

Uplink: 435.150 – 435.130 MHz LSB (Inverting)
Downlink: 145.950 – 145.970 MHz USB
Telemetry Tx: 145.935 MHz BPSK

(The passband may be up to 15kHz higher depending on on-board temps. Lower temperatures give higher freqs!)

Starship Lifts Off On Third Test Flight

SpaceX’s Starship vehicle lifted off on its third test flight March 14, making significant progress compared to its first two by achieving most of its planned test milestones.

The Starship/Super Heavy vehicle lifted off from the company’s Starbase site at 9:25 a.m. Eastern. The liftoff was delayed by nearly an hour and a half because of ships in restricted waters offshore. SpaceX reported no technical issues during the countdown.

[Starship lifts off on its third integrated test flight March 14. Credit: SpaceX webcast]

The Super Heavy booster fired all 33 of its Raptor engines for nearly three minutes before executing “hot staging”, with the Starship upper stage’s engines igniting while still attached to Super Heavy before separating.

The booster then performed burns to attempt what SpaceX webcast hosts called a “soft splashdown” in the Gulf of Mexico, where it would not be recovered. However, the landing burn did not appear to go correctly, and the company later said that the booster broke apart 462 meters above the ocean after lighting several Raptor engines for a landing burn.

The Starship upper stage performed its burn, placing the vehicle onto its planned suborbital trajectory. It avoided the fate of the previous Starship launch in November, when the vehicle broke apart late in its burn after catching fire while venting propellant.

While in space on its suborbital trajectory, SpaceX opened a payload bay door that will be used on later Starship vehicles for deploying Starlink satellites. It also performed an in-space propellant transfer demonstration as part of a NASA contract where it would move propellant from one tank within the vehicle to another. SpaceX said it was evaluating the data from both tests.

SpaceX had planned to perform a brief relight of a Raptor engine on Starship about 40 minutes after liftoff, but the company said on the webcast that this test was skipped for reasons not immediately known. The company later said the engine test was called off because of the vehicle’s roll rates.

Several minutes later, the vehicle started reentry. A camera mounted on a flap on Starship provided dramatic images of the reentry, relayed through Starlink satellites. Telemetry was lost about 49 and a half minutes after liftoff when the vehicle was descending through an altitude of 65 kilometers. SpaceX later said on the webcast that it lost contact through both its own Starlink satellites as well as through NASA TDRSS data relay satellites at the same time, speculating that the vehicle may have broken up.

While the mission did not achieve all its test objectives, the company considered the launch a success. “What we achieved on this flight will provide invaluable data to continue rapidly developing Starship,” it said in a statement.

NASA’s SpaceX Crew-7 Finishes Mission, Returns to Earth

The SpaceX Crew Dragon Endeavour spacecraft, with NASA astronaut Jasmin Moghbeli, KI5WSL, ESA (European Space Agency) astronaut Andreas Mogensen, KG5GCZ, Japan Aerospace Exploration Agency (JAXA) astronaut Satoshi Furukawa, KE5DAW, and Roscosmos cosmonaut Konstantin Borisov aboard, splashed down in the Gulf of Mexico off the coast of Pensacola, Florida, on Tuesday, March 12, 2024. Moghbeli, Mogensen, Furukawa, and Borisov are returning after nearly six-months in space as part of Expedition 70 aboard the International Space Station.

The Crew-7 mission lifted off  at 3:27 a.m. on Aug. 26, 2023, on a Falcon 9 rocket from NASA’s Kennedy Space Center in Florida. About 30 hours later, Dragon docked to the Harmony module’s space-facing port. Crew-7 undocked at 11:20 a.m. Monday, March 11, to begin the trip home.

Moghbeli, Mogensen, Furukawa, and Borisov traveled 84,434,094 miles during their mission, spent 197 days aboard the space station, and completed 3,184 orbits around Earth. The Crew-7 mission was the first spaceflight for Moghbeli and Borisov. Mogensen has logged 209 days in space over his two flights, and Furukawa has logged 366 days in space over his two flights.

[A thermal screenshot showing the successfully deployed four parachutes of the Dragon Capsule as it makes its descent on March 12]

Throughout their mission, the Crew-7 members contributed to a host of science and maintenance activities and technology demonstrations, including a number of ARISS amateur radio contacts. Moghbeli conducted one spacewalk, joined by NASA astronaut Loral O’Hara, replacing one of the 12 trundle bearing assemblies on the port solar alpha rotary joint, which allows the arrays to track the Sun and generate electricity to power the station.

The crew contributed to hundreds of experiments and technology demonstrations, including the first study of human response to different spaceflight durations, and an experiment growing food on the space station.

This was the third flight of the Dragon spacecraft, named Endurance. It also previously supported the Crew-3 and Crew-5 missions. The spacecraft will return to Florida for inspection and processing at SpaceX’s refurbishing facility at Cape Canaveral Space Force Station, where teams will inspect the Dragon, analyze data on its performance, and process it for its next flight.

The Crew-7 flight is part of NASA’s Commercial Crew Program and its return to Earth follows on the heels of NASA’s SpaceX Crew-8 launch, which docked to the station March 5, beginning another science expedition. That crew consists of Matthew Dominick, KCØTOR, Michael Barratt, KD5MIJ, Jeanette Epps, KF5QNU, and Alexander Grebenkin, RZ3DSE.

Satellite Shorts From All Over

+ NASA has terminated its OSAM-1 mission, a multibillion-dollar endeavor aimed at showcasing robotic satellite servicing technology in space, due to ongoing technical, cost, and schedule challenges. Originally intended to demonstrate satellite refueling, the mission expanded to include in-orbit assembly, incorporating a 16-foot robotic arm named SPIDER. Despite significant congressional funding, the project faced continual delays and ballooning costs, reaching $1.5 billion with an estimated additional cost of nearly $1 billion for launch. Changes in the satellite servicing market, with a shift towards alternative technologies like Northrop Grumman’s Mission Extension Vehicle, contributed to the cancellation. Maxar, the prime contractor for OSAM-1, faced criticism for poor performance, leading to delays and cost overruns, although the company cited other factors like the COVID-19 pandemic. The cancellation impacts approximately 450 workers at NASA’s Goddard Space Flight Center, prompting NASA to review strategies to mitigate workforce impacts and consider alternative uses for developed technologies. (ANS thanks Ars Technica, for the above information.)

+ China’s human spaceflight agency, CMSA, is progressing towards its goal of landing astronauts on the moon before 2030. The spacecraft developed for this purpose has been named Mengzhou, translating to “Dream Vessel,” for lunar missions, and Lanyue, meaning “Embracing the Moon,” for orbital travel. These names were selected through a public contest, with Mengzhou having a variant for low Earth orbit (LEO) carrying seven astronauts and a moon version transporting three astronauts into lunar orbit. The China Aerospace Science and Technology Corporation (CASC) is designing and building the spacecraft and lander, along with a new rocket, the Long March 10. The moon landing plan involves two Long March 10 rockets launching Mengzhou and Lanyue, rendezvousing in lunar orbit, with astronauts descending to the lunar surface. A 440-pound crew rover will accompany the lunar lander. Progress on various mission hardware is reportedly on track, including completed development of the primary spacecraft and technical proposals for launch and landing sites. Recently, models of the rocket, spacecraft, and lander were showcased at an exhibition in Shanghai. (ANS thanks Space.com, for the above information.)

+ U.S. regulators have approved ground rules for allowing SpaceX and other satellite operators to use radio waves from terrestrial mobile partners to keep smartphone users connected outside cell tower coverage. The Federal Communications Commission voted March 14 unanimously in favor of its Supplemental Coverage from Space (SCS) regulatory framework. SCS providers would operate as a secondary service to companies providing Mobile Satellite Services (MSS) with conventional frequencies already approved for use from space. This means an SCS operator would have to immediately cease operations if they interfere with an MSS provider or terrestrial telco with primary rights. (ANS thanks SpaceNews for the above information.)

+ A rocket made by a Japanese company exploded seconds after launch on Wednesday, in a spectacular failure for the start-up’s bid to put a satellite into orbit. Tokyo-based Space One’s 18-metre (60-foot) Kairos rocket blasted off in the coastal Wakayama region of western Japan, carrying a small government test satellite. But around five seconds later, the solid-fuel rocket erupted in fire, sending white smoke billowing around the remote mountainous area as orange flames raged on the ground, live footage showed. Space One said it had taken the decision to “abort the flight” and details were being investigated. (ANS thanks Space Daily for the above information.)

SpaceX’s Transporter-10 Successfully Launches Over Fifty Satellites

SpaceX successfully executed its tenth Transporter rideshare mission, showcasing the continued high demand for satellite deployment services. The flawless launch took place at Vandenberg Space Force Base, on March 4th at 5:05 p.m. EST, where a Falcon 9 rocket carried 53 small satellites into orbit. While this success underscores the persistent need for such services from satellite developers, it also brings attention to emerging challenges in maintaining space situational awareness.

Among the diverse payloads was SONATE-2, a 6U+ CubeSat developed by the University of Wuerzburg in Germany. This satellite serves as a technology demonstration for artificial intelligence hardware, software, and machine learning techniques, coupled with an educational component through the DLR School Lab. SONATE-2’s amateur payload includes a VHF transceiver and an AI payload with optical sensors, providing regular SSTV downlinks, an APRS digipeater, and CW beacon.

The mission aims to engage students in aerospace and computer science engineering programs, offering practical skills and participation in satellite operations. SONATE-2 reported successful operation, with over 1000 telemetry frames downloaded in the first day post-launch, indicating a safe and stable state of the satellite.

Startups such as Unseenlabs, Loft Orbital, Atomos Space, True Anomaly, Quantum Space, and Sidus Space seized the opportunity, deploying their first satellites. This diverse array of payloads highlights the industry’s commitment to pushing boundaries in space exploration. Another notable payload, MethaneSAT, developed by Ball Aerospace for the Environmental Defense Fund, aims to track global methane emissions with high-resolution precision, contributing to environmental monitoring efforts.

Despite the success of Transporter-10, challenges in space situational awareness have surfaced. Owen Marshall of LeoLabs highlighted a degradation in cataloging objects after launch, particularly in rideshare missions where the median catalog time can exceed two weeks. This delay poses risks to satellite operators’ communication capabilities, emphasizing the need for enhanced tracking capabilities in the era of growing satellite deployments.

As the space industry evolves, addressing these challenges becomes crucial to ensure the sustainability and safety of activities in Earth’s orbit. The success of SpaceX’s Transporter-10 mission underscores the industry’s vitality, but the spotlight on emerging challenges signals the need for continual innovation and collaboration to navigate the complexities of our expanding presence in space.

Vostochny Spaceport Sends Meteor-M2-4 Weather Satellite Into Orbit

On February 29, 2024, the Vostochny spaceport witnessed the successful launch of a Soyuz-2-1b rocket, inaugurating the first mission of the year from this spaceport. On board was the Meteor-M2-4 weather spacecraft, a notable addition to the Meteor-M series, alongside several secondary payloads, including an Iranian micro-satellite dedicated to Earth observation.

Developed by the Moscow-based VNIIEM Corporation, Meteor-M2-4, weighing nearly three tons, boasts advanced instruments designed for comprehensive monitoring of global weather patterns, the ozone layer, ocean surface temperature, and ice conditions. Recognized for its military applications by the Russian space agency, Roskosmos, this mission marked a significant stride in space exploration.

Meteor-M2-4 encountered delays in its journey, originally slated for a December 26, 2023 launch. However, due to multiple rescheduling, the liftoff finally took place on February 29, 2024. The spacecraft, delivered to the launch site on December 28, 2023, underwent meticulous preparations, including fueling and integration with the launch vehicle, ultimately culminating in a successful liftoff.

Following the standard ascent profile for Meteor satellites, the launch trajectory headed northwest over eastern Russia, reaching a near-polar orbit with an inclination of approximately 98.57 degrees. The fairing protecting the payload separated during the second stage operation, with subsequent stage separations carefully planned for safe impact zones in the Amur Region and the Sakha Republic.

The Fregat upper stage took charge of the final payload deployment, executing precise maneuvers over the Arctic and Antarctica. Approximately 59 minutes and 46 seconds after liftoff, the Meteor-M2-4 satellite was successfully released, accomplishing its primary mission. The Fregat then proceeded to deploy the secondary payloads into their designated orbits.

The Russian Meteor M2-4 satellite commenced transmitting weather images within the first day in orbit. Known for their accessibility to amateur users, Meteor M satellites operate around 137 MHz, making them receivable with a RTL-SDR dongle and suitable satellite antennas. The satellite also transmits in the L-band, enabling reception with a 60cm or larger dish and motorized or hand tracking. Unlike previous satellites in the series, M2-4 experienced a smooth launch and deployment, with reports indicating excellent signal strength and clear image reception in both VHF and L-band frequencies. Two-Line Elements (TLE’s) and the SatDump decoding software (https://github.com/SatDump/SatDump) have been updated to support Meteor M2-4, simplifying access for enthusiasts through Github updates.

Space historian Jonathan McDowell shared valuable insights into the flight, detailing each Fregat maneuver and its impact on the satellite cluster. While the majority of the secondary payloads adhered to the expected orbits, anomalies in the deployment of some SITRO satellites prompted further investigation. The launch of Meteor-M2-4 and its accompanying payloads stands as a noteworthy accomplishment for Russia’s space program, contributing significantly to global endeavors in weather monitoring, Earth observation, and satellite technology development.

(ANS thanks NASA for the above information)

+ SpaceX is aiming for the third test flight of its Starship rocket on March 14, as announced through a post on the X platform. The Starship vehicle comprises a stainless-steel reusable upper stage, also known as Starship, and a Super Heavy first-stage booster, standing over 400 feet tall together. A recent critical fueling test at the Starbase facility in Texas involved pumping over 10 million pounds of liquid methane and liquid oxygen into the rocket. The upcoming launch follows two previous test flights in April 2023 and November 2023, where Starship faced issues like failure to separate from the first-stage booster and a subsequent explosion of the Super Heavy. After the second test, the FAA identified seventeen corrective actions, all of which SpaceX claims to have completed, addressing issues related to leak reduction, fire protection, and propellant vent operations. The Starship and Super Heavy, designed for full reusability, are pivotal for NASA’s Artemis 3 mission to land astronauts on the moon by 2026. (ANS thanks Brett Tingley, Space.com, for the above information)

+ NASA has identified a growing air leak on the International Space Station (ISS) located at the end of the Russian service module. The leak, situated in Russia’s Zvezda service module, initially released one pound of air per day but accelerated to over two pounds daily in early February. Despite the increased rate, NASA assures that it does not currently jeopardize the safety of the ISS crew or impact the station’s operations. Collaboration between the United States, Russia, Europe, Japan, and Canada is underway to address the situation. Roscosmos, the Russian space agency, confirms ongoing monitoring and asserts that there is no immediate threat to the crew or the station itself. The leak is in a three-foot-long area and has prompted precautionary measures, including sealing off the affected vestibule to mitigate further air loss from the rest of the space station. (ANS thanks Will Sullivan, Smithsonian Magazine, for the above information)

+ The inaugural components for Europe’s new Ariane 6 rocket have reached the port of Pariacabo in Kourou, French Guiana, transported by the container ship, Canopée. Manufactured across Europe, the central core arrived on Canopée, which uses sails to reduce emissions and save up to 30% on fuel during its 10-day, 7,000 km journey. The rocket’s stages were produced in various European locations, with the main engine and stage integrated in Les Mureaux, France, and the upper stage and insulation in Bremen, Germany. Following transport, the components were offloaded and taken to the Ariane 6 assembly building, a few kilometers away, where they will undergo integration before liftoff. The boosters, already at Europe’s Spaceport, are P120C solid propulsion boosters similar to those used for the Vega-C rocket. The central core will be assembled horizontally and then transported to the launchpad, where it will be erected, followed by the addition of boosters and the upper stage, with the goal of a summer launch for Flight Model-1.
