NASA Astronaut Loral O’Hara, Crewmates Return from ISS

NASA astronaut Loral O’Hara, KI5TOM, returned to Earth after a six-month research mission aboard the International Space Station on April 6, along with Roscosmos cosmonaut Oleg Novitskiy, and Belarus spaceflight participant Marina Vasilevskaya.

The trio departed the space station aboard the Soyuz MS-24 spacecraft at 03:54 UTC, and made a safe, parachute-assisted landing at 07:17 (12:17 p.m. Kazakhstan time), southeast of the remote town of Dzhezkazgan, Kazakhstan.

O’Hara launched Sept. 15, 2023, alongside Roscosmos cosmonauts Oleg Kononenko, RN3DX, and Nikolai Chub, who both will remain aboard the space station to complete a one-year mission. Novitskiy and Vasilevskaya launched aboard Soyuz MS-25 on March 23 along with NASA astronaut Tracy C. Dyson, who will remain aboard the orbiting laboratory until this fall.

O’Hara spent a total of 204 days in space as part of her first spaceflight. She completed approximately 3,264 orbits of the Earth and a journey of more than 86.5 million miles. O’Hara worked on scientific activities aboard the space station, including investigating heart health, cancer treatments, and space manufacturing techniques during her stay aboard the orbiting laboratory.

Following post-landing medical checks, the crew returned to the recovery staging city in Karaganda, Kazakhstan. O’Hara then boarded a NASA plane bound for her return to the agency’s Johnson Space Center in Houston.

New NASA Strategy Envisions Sustainable Future for Space Operations

To address a rapidly changing space operating environment and ensure its preservation for generations to come, NASA released the first part of its integrated Space Sustainability Strategy, on April 9, advancing the agency’s role as a global leader on this crucial issue.

“The release of this strategy marks true progress for NASA on space sustainability,” said NASA Deputy Administrator Pam Melroy. “Space is busy – and only getting busier. If we want to make sure that critical parts of space are preserved so that our children and grandchildren can continue to use them for the benefit of humanity, the time to act is now. NASA is making sure that we’re aligning our resources to support sustainable activity for us and for all.”

For decades, NASA has served as a proactive leader for responsible and sustainable space operations. Entities across the agency develop best practices, analytic tools, and technologies widely adopted by operators around the world. The new strategy seeks to integrate those efforts through a whole-of-agency approach – allowing NASA to focus its resources on the most pressing issues. To facilitate that integration, NASA will appoint a new director of space sustainability to coordinate activities across the agency.

Key aspects of our approach include providing global leadership in space sustainability, supporting equitable access to space, and ensuring NASA’s missions and operations enhance space sustainability.

Space environments currently are seeing the rapid emergence of commercial capabilities, many of them championed by NASA. These capabilities include increased low Earth orbit satellite activity and plans for the use of satellite constellations, autonomous spacecraft, and commercial space destinations. However, this increased activity also has generated challenges, such as an operating environment more crowded with spacecraft and increased debris. Understanding the risks and benefits associated with this growth is crucial for space sustainability.

Developed under the leadership of a crossagency advisory board, the space sustainability strategy focuses on advancements NASA can make toward measuring and assessing space sustainability in Earth orbit, identifying cost-effective ways to meet sustainability targets, incentivizing the adoption of sustainable practices through technology and policy development, and increasing efforts to share and receive information with the rest of the global space community.

NASA’s approach to space sustainability recognizes four operational domains: Earth, Earth orbit, the orbital area near and around the Moon known as cislunar space, and deep space, including other celestial bodies. The first volume of the strategy focuses on sustainability in Earth orbit. NASA plans to produce additional volumes focusing on the other domains.

Trash From The ISS May Have Hit A House In Florida

A few weeks ago, something from the heavens came crashing through the roof of Alejandro Otero’s Florida home, and NASA is on the case.

Otero wasn’t home at the time. A Nest home security camera captured the sound of the crash at 2:34 pm local time (19:34 UTC) on March 8. That’s an important piece of information because it is a close match for the time—2:29 pm EST (19:29 UTC)—that US Space Command recorded the reentry of a piece of space debris from the space station. At that time, the object was on a path over the Gulf of Mexico, heading toward southwest Florida.

In all likelihood, this nearly 2-pound object came from the International Space Station.
Otero said it tore through the roof and both floors of his two-story house in Naples, Florida.

This space junk consisted of depleted batteries from the ISS, attached to a cargo pallet that was originally supposed to come back to Earth in a controlled manner. But a series of delays meant this cargo pallet missed its ride back to Earth, so NASA jettisoned the batteries from the space station in 2021 to head for an unguided reentry.

NASA has recovered the debris from the homeowner, according to Josh Finch, an agency spokesperson. Engineers at NASA’s Kennedy Space Center will analyze the object “as soon as possible to determine its origin,” Finch told Ars. “More information will be available once the analysis is complete.”

The entire pallet, including the nine disused batteries from the space station’s power system, had a mass of more than 2.6 metric tons (5,800 pounds), according to NASA. Size-wise, it was about twice as tall as a standard kitchen refrigerator. It’s important to note that objects of this mass, or larger, regularly fall to Earth on guided trajectories, but they’re usually failed satellites or spent rocket stages left in orbit after completing their missions.

In a post on X, Otero said he is waiting for communication from “the responsible agencies” to resolve the cost of damages to his home. If the object is owned by NASA, Otero or his insurance company could make a claim against the federal government under the Federal Tort Claims Act, according to Michelle Hanlon, executive director of the Center for Air and Space Law at the University of Mississippi.

“It gets more interesting if this material is discovered to be not originally from the United States,” she told Ars. “If it is a human-made space object which was launched into space by another country, which caused damage on Earth, that country would be absolutely liable to the homeowner for the damage caused.”

This could be an issue in this case. The batteries were owned by NASA, but they were attached to a pallet structure launched by Japan’s space agency.

NASA typically doesn’t want large chunks of space debris falling to Earth with an uncontrolled reentry. You can trace the reason this object came down unguided back to a Russian launch failure more than five years ago. NASA astronaut Nick Hague and Russian commander Alexey Ovchinin aborted their launch on a Soyuz spacecraft when their rocket failed shortly after liftoff.

One of Hague’s jobs at the International Space Station would have been to go outside on spacewalks to help install a new set of lithium-ion batteries recently delivered by a Japanese HTV cargo ship. But Hague didn’t reach the station in 2018, so NASA put off the spacewalks until a new team of astronauts arrived at the complex.

This interruption to the space station’s carefully choreographed schedule threw off the entire multiyear plan for upgrading the batteries on the outpost’s electrical system. Instead of putting the old batteries back into the HTV for a guided destructive reentry over the open ocean, NASA held onto the cargo pallet at the station when the HTV supply ship needed to depart.

Each of the subsequent HTV missions delivered more fresh batteries to the space station and then departed the complex with the cargo pallet and decommissioned batteries from the previous HTV mission. That was the case until there were no more HTVs to fly. Japan’s last HTV spacecraft departed the ISS in 2020 with the cargo pallet and batteries from the prior flight, stranding the last battery pallet at the station.

The space station’s other cargo vehicles—SpaceX’s Dragon, Northrop Grumman’s Cygnus, and the Russian Progress—can’t accommodate the HTV cargo pallet.

So NASA decided to jettison the battery pallet using the space station’s robotic arm in March 2021 in order to free up real estate on the lab. Without any propulsion of their own, the batteries were adrift in orbit for three years until aerodynamic drag finally pulled the pallet back into the atmosphere on March 8, almost exactly three years later.

It is notoriously difficult to predict where a piece of space junk will reenter the atmosphere. US Space Command precisely tracks tens of thousands of objects in Earth orbit, but the exact density of the upper atmosphere is still largely an unknown variable. Even a half-day before the reentry, US Space Command’s estimate for when the battery pallet would fall to Earth had a window of uncertainty spanning six hours, enough time for the object to circle the planet four times.

And if you don’t know when something will reenter the atmosphere, you can’t predict where it will come down.

If NASA confirms the projectile that fell through Otero’s house last month came from the ISS, it would join a small handful of incidents when an object falling out of orbit damaged someone’s property.

Earth is a big place. It’s fairly common for someone to find a piece of fallen space junk in a field or washed up on a beach. But it is rare for a reentry to hit a structure or injure a person.

Falling space debris has never killed anyone. According to ESA, the annual risk of an individual human being injured by space debris is less than 1 in 100 billion.

Changes to AMSAT-NA TLE Distribution for April 12

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.

Ending an Era, Final Delta Rocket Launched This Week

Ending an era in U.S. rocketry, United Launch Alliance fired off its 16th and final triple-core Delta 4 Heavy Tuesday, launching a classified spy satellite in the last hurrah of a storied family of rockets dating back to the dawn of the space age.

The Heavy’s three hydrogen-fueled RS-68A first stage engines ignited with a rush of bright orange flame at 12:53 p.m. EDT, smoothly pushing the 235-foot-tall rocket away from pad 37 at the Cape Canaveral Space Force Station in Florida.

The launch came 12 days late, primarily because of work to replace a pump in a system that supplies nitrogen gas to multiple launch pads from a pipeline running through the Kennedy Space Center and the Cape Canaveral Space Force Station. There were no problems Tuesday.

Mounted atop the rocket was a classified satellite provided by the National Reconnaissance Office, the secretive government agency that manages the nation’s fleet of sophisticated optical and radar imaging reconnaissance satellites and electronic eavesdropping stations.

In keeping with standard NRO-U.S. Space Force policy for such missions, no details about the NROL-70 payload were released. But about six hours after launch, the National Reconnaissance Office declared the launch a success, indicating the satellite reached its planned orbit.The final appearance of a Delta rocket 63 years after the first variant’s maiden flight was an emotional milestone for the managers, engineers and technicians who assembled and launched the last member of the family.

The Delta family of stages and rockets had its roots in the early space program, first serving in the nation’s fleet of intermediate-range ballistic missiles and evolving through multiple versions used to put military, NASA and civilian payloads into orbit.

The now-retired Delta 2 debuted in 1990, putting the first Global Positioning System satellites into orbit and sending multiple planetary probes into deep space, including Messenger to Mercury, multiple Mars orbiters, the Pathfinder, Spirit and Opportunity Mars rovers, the Spitzer Space Telescope and many more.

The single-core Delta 4 first flew in 2002 with the first Heavy following two years later. The single-core version flew the program’s final flight in 2019. Tuesday’s launch was the 45th flight of a Delta 4 and the 16th and final Delta 4 Heavy.

“Launching the last Delta 4 is bittersweet for me,” Col. Eric Zarybnisky, director of NRO’s Office of Space Launch, said in a statement. “I was part of the team that launched the first Delta 4 for the NRO. Since that time, the Delta 4 has put amazing capability on orbit for this nation.”

Tory Bruno, president and CEO of United Launch Alliance, also called the flight a “bittersweet” moment as the company continues its transition to next-generation Vulcan rockets, phasing out its more expensive Delta and Atlas families.

“Soon, Vulcan will pick up that mantle and we’re going to retire this venerable rocket that has made so much important work for our country,” he said after launch in a pre-recorded video.

Satellite Shorts From All Over

+ NASA now knows what knocked Voyager 1 offline, but it will take a while to fix. Voyager 1’s remaining Flight Data Subsystem (its redundant copy failed in 1982) is the reason that the distant spacecraft is currently offline. Voyager’s FDS were the first computers on a spacecraft to use volatile memory. Unfortunately, one of Voyager 1’s FDS memory chips is malfunctioning—NASA hopes they can work around it, but it will likely take months.(ANS thanks The Orbital Index for the above information.)

+ Following repairs to a liquid oxygen leak in the Falcon Heavy’s core booster, NASA and SpaceX have rescheduled the launch of the GOES-U satellite, the final installment in NOAA’s GOES-R Series, for June 25. The adjustment aims to ensure thorough examination and resolution of the issue, discovered during a routine inspection in February. With preparations now back on track, the deployment of GOES-U from Kennedy Space Center’s Launch Complex 39A will proceed using a SpaceX Falcon Heavy rocket. Managed cooperatively by NOAA and NASA, the GOES-R Series Program encompasses satellite operations, data dissemination, and ground systems oversight, with NASA’s Goddard Space Flight Center leading spacecraft acquisition and instrument development. Lockheed Martin’s contributions include design, construction, and testing of the satellites, while L3Harris Technologies has provided key instruments and ground systems essential for capturing atmospheric observations.

+ The European Union is poised to finalize a security deal with the United States, enabling payments to Elon Musk’s SpaceX for satellite launches due to delays in Europe’s Ariane rocket system. Approved by national general affairs ministers, the agreement grants European Union and European Space Agency (ESA) personnel continuous access to launch facilities and prioritized debris retrieval rights in case of SpaceX rocket failures. With a 200 million deal already struck last year, SpaceX is contracted to launch four Galileo satellites as Ariane 6 faces further delays. While Ariane 6 is slated for a summer launch, commercial missions await later scheduling. The arrangement with SpaceX allows for two Galileo satellite launches this year, necessitated by Soyuz launcher cancellations and Ariane 6 delays. The security pact ensures access to classified Galileo equipment, with provisions for debris retrieval and a sunset clause by 2027 to address concerns about reliance on SpaceX over Ariane. (ANS thanks Joshua Poaaner, Politico Europe, for the above information)

+ NASA has been tasked by the White House to establish a lunar-centric time reference system, known as Coordinated Lunar Time (LTC), to aid missions requiring extreme precision on the moon. The agency has until the end of 2026 to set up LTC, which is not akin to Earth’s time zones but provides a frame of time reference for the moon. LTC will accommodate the slightly faster passage of time on the moon, approximately 58.7 microseconds each day compared to Earth, due to its lower gravity. It will serve as a benchmark for timekeeping for lunar spacecraft and satellites, crucial for their missions. NASA’s Artemis program, set to begin astronaut missions to the lunar surface in 2026, necessitates LTC for synchronization among Earth, lunar satellites, bases, and astronauts, without which data transfers and communications could be compromised. Developing LTC will require international agreements, possibly influenced by the Universal Coordinated Time (UTC) standard, with potential implementation involving atomic clocks on the moon and adherence to existing space agreements like the Artemis accords.

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.

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.

+ 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.

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.

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.)

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.

+ 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.

+ 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.
