TEVEL Satellites Begin Atmospheric Reentry and Decommissioning

The TEVEL satellite project, featuring a series of CubeSats designed and built by Israeli students, has entered its final phase with the beginning of atmospheric reentry and decommissioning. This initiative, a collaboration between the Israel Space Agency (ISA) and Tel Aviv University, has been a key educational tool, providing practical experience in satellite technology to students across Israel.

Launched in January 2022 on the SpaceX Falcon 9 Transporter-3 mission, the TEVEL satellites were part of a broader effort to promote STEM education. The CubeSats, built to the 10x10x10 cm standard, were used for various missions including scientific data collection, amateur radio communication, and technology experimentation. The project aimed to enhance students’ understanding of satellite technology and prepare them for careers in the space industry.

In addition to their educational value, the TEVEL satellites played a significant role in the amateur radio community. Equipped with radio transponders, they allowed amateur radio operators worldwide to communicate via satellite, fostering international collaboration and technological experimentation. This feature provided a unique platform for enthusiasts to engage in satellite communication.

As the satellites now re-enter Earth’s atmosphere, this phase marks the end of their operational lives. The reentry process, which involves the satellites burning up upon reentry to prevent space debris, is being monitored by both educational teams and the broader space community. This final stage offers a valuable learning opportunity for students tracking the satellites’ descent and analyzing the data.

Looking ahead, David Greenberg, 4X1DG, has announced a new TEVEL mission featuring nine additional satellites, continuing the educational and amateur radio goals of the original initiative. The decommissioning of the TEVEL satellites highlights the importance of responsible satellite disposal to minimize space debris and ensure the sustainability of space operations.

The success of the TEVEL project sets a precedent for future educational satellite initiatives, demonstrating how hands-on learning can be integrated with practical space missions. As the satellites complete their final descent, they leave behind a legacy of inspiration and international collaboration in both educational and amateur radio fields.

Ariane 6 Launches PariSat: Young Engineers Test Heat Dissipation

On July 9, 2024, Europe’s newest rocket, the Ariane 6, launched with a range of missions on board, each with unique objectives and dedicated teams. Among these missions was PariSat, a project that highlights the ingenuity and dedication of the Garef Aérospatial club. This amateur space club, comprised of young engineers aged 15 to 25, has been working diligently on satellite testing, with the goal of exploring how different materials handle heat dissipation in space.

The core of the PariSat experiment is to determine which materials are most effective at dissipating heat in the harsh environment of space. The project, however, is not just about the scientific results but also about the educational journey for the young engineers involved. Based in a modest building near the Georges Carpentier stadium in Paris’s 13th district, the club members work after school, applying their passion for space to design and build their satellite experiment.

PariSat features eight small square plates, each just 4 cm wide, which function as space radiators. These plates were chosen to test various properties such as material composition and color, and their responses to heating and cooling. Equipped with temperature sensors, each plate provided data on “black-body radiation” during the nearly three-hour flight of Ariane 6’s upper stage. This data will help validate the Stefan-Boltzmann law of thermal radiation, a principle discovered in 1884.

In addition to the scientific experiment, PariSat includes a photo component. The team has adapted a GoPro camera for space use, which is controlled by a module entirely designed by Garef Aérospatial. This camera, featuring a fisheye lens, captured stunning images of Earth, showcasing the planet’s curvature and adding a visual dimension to the mission.

PariSat is part of a larger set of five experiments, including Peregrinus, Sidloc, LiFi, and YPSat, which also remained attached to the Ariane 6’s upper stage during its three-hour flight. These experiments gathered data as the upper stage’s orbit was adjusted by the Vinci engine, which can be restarted multiple times. The collected data was transmitted back to Earth and received by the Swedish Space Corporation’s telemetry station in Kiruna, Sweden.

As the Garef Aérospatial team begins analyzing the data, the PariSat mission serves as a testament to the capabilities of young engineers and highlights the potential for youth-led initiatives in space science. With this mission, the team looks forward to future projects, driven by the experiences and successes gained from their participation in Ariane 6’s first flight.

SpaceX to Develop Enhanced Dragon Spacecraft for ISS Deorbit

SpaceX will develop an enhanced version of its Dragon spacecraft for NASA to deorbit the International Space Station (ISS) at the end of its operational life. This development comes as part of a contract awarded to SpaceX on June 26, valued at up to $843 million. The new spacecraft, known as the United States Deorbit Vehicle (USDV), was detailed by NASA and SpaceX officials at a briefing on July 17th.

The USDV will be based on SpaceX’s existing Dragon spacecraft but will feature a redesigned and larger trunk section with additional thrusters. Specifically, the USDV will have 46 Draco thrusters, including 16 for attitude control and 30 for the maneuvers required to lower the ISS’s orbit. Sarah Walker, SpaceX’s director of Dragon mission management, explained that the enhanced trunk section is twice as long as the regular one.

The new trunk will house engines, propellant tanks, power generation, and other systems, storing six times the propellant of the current Dragon spacecraft and generating three to four times the power. “It’s almost a spacecraft in and of itself,” Walker noted. Once completed, NASA will own and operate the USDV, which will be launched to the ISS shortly after the station’s final crew arrives.

After its arrival and successful checkout, ISS controllers will allow the station’s orbit to naturally decay. The final crew will depart when the station’s altitude decreases from its current 400 kilometers to 330 kilometers. The ISS’s orbit will continue to decay over approximately six months before NASA uses the USDV for a final controlled deorbit, targeting a remote ocean corridor about 2,000 kilometers long.

Dana Weigel, NASA ISS program manager, mentioned that debris from the station, ranging in size from a microwave oven to a sedan, is expected to survive reentry and splash down in this corridor. The USDV will have an estimated mass of over 30,000 kilograms, including 16,000 kilograms of propellant. Due to its size, it will require a heavier class of rocket than the Falcon 9 currently used for Dragon missions. NASA plans to procure the launch vehicle separately at least three years before the launch.

SpaceX expressed readiness to support the launch if given the opportunity. Northrop Grumman was the only other company to bid on the USDV. NASA’s source selection statement indicated that Northrop’s bid was significantly higher in price and rated lower in both mission suitability and past performance compared to SpaceX. Ken Bowersox, NASA associate administrator for space operations, expressed satisfaction with the proposals received, noting he was pleased with the submissions from SpaceX and Northrop Grumman.

Satellite Shorts From All Over

+ ASRTU-1 is a 12U CubeSat mission developed by students from the Harbin Institute of Technology and Bauman State Technical University. It is designed for educational purposes and features an amateur radio SDR payload. The satellite will offer telecommand uplink and telemetry/digital image downlink capabilities. Harbin Institute of Technology, known for developing successful amateur radio satellites like LilacSat-2 and DSLWP-B, has created a new SDR-based transceiver for ASRTU-1. This transceiver will provide communication resources, including a V/U FM transponder, UHF telemetry downlink, and a 10.5G image downlink. Scheduled to launch from Vostochny Cosmodrome on November 2024, ASRTU-1 will operate in a 530km sun-synchronous orbit with coordinated downlinks on 436.210 MHz, 435.400 MHz, and 10460.00 MHz and a repeater uplink on 145.875 MHz. (ANS thanks @AKAhamradio, X.com, for the above information)

+ SpaceX successfully test-fired the engines on its Super Heavy booster on July 15, 2024, in preparation for the fifth integrated flight test (IFT-5) of its Starship vehicle. This upcoming launch, expected in August, will be the most ambitious to date and aims to build on the success of previous flights. The Super Heavy booster, measuring 233 feet tall, fired its 33 Raptor engines at full thrust for about 20 seconds during the static test at SpaceX’s Starbase facility in Texas. Starship, which has been selected by NASA for the Artemis 3 lunar mission, is designed as a fully reusable system capable of carrying humans to Mars. Unlike SpaceX’s Falcon 9, the Super Heavy booster is intended to return directly to its launch pad, where it will be caught midair by the launch tower’s “chopstick” arms. With each test flight achieving progressively more, SpaceX aims to test the booster catch system in the upcoming launch, marking a significant advance towards rapid reusability and future missions. (ANS thanks Josh Dinner, Space.com, for the above information)

+ The 188,000-pound, 212-foot-tall core stage for the Artemis-2 moon mission has arrived at NASA’s Kennedy Space Center (KSC) following a 900-mile journey from Michoud Assembly Facility in New Orleans. This milestone marks a significant step in preparing for the Artemis-2 mission, which aims to return humans to the moon for the first time in over fifty years. NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian astronaut Jeremy Hansen are slated to launch on this mission as early as September 2025. Upon arrival at KSC, the core stage was transferred to a self-propelled transporter and moved into the iconic Vehicle Assembly Building (VAB). Engineers will soon begin processing the stage for stacking operations, involving the integration of the twin Solid Rocket Boosters (SRBs) and the spacecraft. The Space Launch System (SLS) rocket’s twin boosters and the core stage’s four RS-25 engines will generate nearly 9 million pounds of thrust at liftoff, propelling Artemis-2 and its crew to the moon. (ANS thanks Mike Killian, AmericaSpace.com, for the above information)

+ NASA astronauts Butch Wilmore and Sunita Williams will remain at the International Space Station (ISS) with no set return date due to ongoing technical issues with Boeing’s Starliner capsule. The astronauts departed for the ISS in early June on a test mission expected to last about a week, but faulty thrusters and helium leaks have delayed their return. Despite some thrusters now functioning normally and the leaks being stable, NASA and Boeing are still not ready to schedule their departure. NASA assures that the astronauts are not stranded and the technical issues do not pose a threat to the mission. Engineers are conducting tests, including on a spare thruster in New Mexico, to understand and resolve the problems. Steve Stich, NASA’s commercial crew program manager, emphasized the priority of the astronauts’ safety and the consideration of backup return options. (ANS thanks Anna Betts, The Guardian, for the above information)

+ SpaceX is set to resume Falcon 9 launches as early as July 27 following the completion of an investigation into an upper stage anomaly from the July 11 launch. The mishap, which resulted in the rocket’s upper stage failing to perform a second burn and stranding Starlink satellites in a low orbit, was attributed to a liquid oxygen leak caused by a cracked sense line. This crack was due to engine vibration fatigue and a loose clamp. The resulting leak led to ice buildup and excessive cooling of engine components, causing a hard start and subsequent damage to the engine hardware. SpaceX has implemented immediate fixes and proposed long-term solutions, and the FAA has determined that there are no public safety issues, allowing launches to proceed. SpaceX is targeting July 27 for the next launch, with two more launches tentatively scheduled for July 28. (ANS thanks Jeff Foust, SpaceNews, for the above information)

Firefly Delivers New Amateur Satellites to Orbit

The Firefly Alpha FLTA005/NASA ELaNa 43 mission, nicknamed “Noise of Summer,” launched successfully at 04:04 UTC on July 4 (Wednesday evening, July 3 in the U.S.) and deployed eight new cube satellites to Low Earth Orbit (LEO). Five of these cubesats carry amateur radio equipment.

The cubesats were placed into a sun-synchronous Earth orbit, meaning that all locations on earth will see high-elevation passes roughly between 8:00 and 10:00 a.m. and between 8:00 and 10:00 p.m. local time daily, with lower elevation passes earlier and later.

Among the newly-deployed satellites, the one of greatest interest to the amateur radio community is MESAT1. Built by the University of Maine, in cooperation with AMSAT, this satellite carries a 30 kHz wide V/U Transponder plus a 1k2 BPSK telemetry downlink. Telemetry downlink 435.800 MHz with transponder downlink 435.810-435.840 MHz, and transponder uplink 145.910-145.940 MHz. Amateurs are encouraged to use AMSAT’s FoxTelem software to collect telemetry.

MESAT1 involves three missions designed by high school students in Maine. The science payloads are climate focused and include ALBEDO, IMAGER, and HAB. These will identify urban heat islands, determine concentration of phytoplankton in water bodies, and help predict harmful algal blooms. Four multispectral cameras on board will relay the data down to University of Maine’s ground station for further processing. Amateurs are encouraged to use AMSAT’s FoxTelem software to collect telemetry and assist in these science projects.

Also deployed was CatSat, a technology demonstration of an inflatable antenna for high-speed communications, built by the University of Arizona. CatSat’s deployable antenna consists of a Mylar balloon. The front half of the balloon is transparent, allowing microwaves to pass through. The back half of the balloon is aluminized, creating a reflecting antenna. After reaching low Earth orbit, CatSat’s antenna will deploy and inflate to a diameter of just over one-and-a-half feet CatSat’s demonstration will be to transmit high-definition Earth photos to 10 GHz, X-band ground stations at ~50 megabits per second.

In addition to images, data about the structure of the Earth’s ionosphere will be gathered by listening-in to thousands of beacons from ground-based ham radio stations. CatSat will relay WSPR and FT8 signals from HF. Downlinks on 437.185 MHz and 10470.00 MHz.

Other satellites with IARU-coordinated amateur frequency downlinks include:

Serenity, which uses a 4k8 FM with AX25 downlink on 437.100 MHz. Serenity was built by Teachers in Space, Inc., a 501(c)(3) nonprofit educational organization in North America that stimulates student interest in science, technology, engineering, and mathematics (STEM). They provide teachers with real space science experiences, space flight opportunities, and industry connections.

Ariane 6 Maiden Flight With GENESIS-A Module

The maiden flight of the new European launcher, Ariane 6, is scheduled for July 9, 2024, with a launch window of 3:00 p.m. to 7:00 p.m. local time from the European spaceport in French Guiana (July 9 20:00h to July 10 00:00h CEST). Among many other payloads, it carries our (inside YPSAT) GENESIS-A module, attached to the second stage of the launcher. The module will transmit FT8 and live SSTV images in Robot 36 format.

FT8 transmissions are made every 16 seconds, while SSTV’s are every 5 minutes.

The working frequencies are as follows:

Downlink 144.175 MHz FT8 Mode:

– Callsign AO4ARI HO60 if the antenna has been deployed
– Callsign AO4ARI HO61 if the antenna has not been deployed

Downlink 144.550 MHz SSTV Robot 36 mode with live image and Hades text

A carrier with a frequency of 144.550 MHz (same frequency as SSTV) is left between FT8 tones.

This information is compiled in PDF in the following document on our web:
https://www.amsat-ea.org/app/download/13458580/AMSAT+EA+-+GENESIS-A+transmissions+description.pdf

The only thing ESA has given us is the trajectory over the ground while flying over Europe, but we don’t have TLEs or anything that we can semi-automate. It is available on our website:
https://www.amsat-ea.org/s/cc_images/cache_19006006.jpg?t=1720182961

It will be very difficult to receive it but we thank you all if you try and if you spread this information to have all possible operators tuned into FT-8 that day. The module will fall into the sea with the second stage after a few hours.

Logbook of The World Returns To Service

Effective 12:00pm ET / 16:00 UTC on July 1, Logbook of The World® (LoTW®) has been to service.

As work progressed on the network, some users encountered LoTW opening briefly during which some 6600 logs were uploaded. The logs were not processed until this weekend as we tested that the interfaces to LoTW were functioning properly.

We are taking steps to help manage what will likely be a huge influx of logs. We are requesting that if you have large uploads, perhaps from contests or from a DXpedition, please wait a week or two before uploading to give LoTW a chance to catch up. We have also implemented a process to reject logs with excessive duplicates. Please do not upload your entire log to “ensure” your contacts are in LoTW as they will be rejected. Lastly, please do not call ARRL Headquarters to report issues you are having with LoTW. You can contact support at [email protected].

Through the end of the year, you may experience planned times when LoTW will be unavailable. We have been using this time to evaluate operational and infrastructure improvements we would like to make to LoTW. Those times will be announced.

We appreciate your patience as we worked through the challenges keeping LoTW from returning to service. We know the importance of LoTW to our members, and to the tens of thousands of LoTW users who are not ARRL members. LoTW, just behind QST, is our second most popular ARRL benefit.

LUSAT, Dead or Alive?

LO-19, co-ordinated by AMSAT Argentina, the LUSAT (named after the LU amateur designation for Argentina) microsatellite was launched on the first ARIANE ASAP flight V35 with SPOT 2, on the 22 January 1990 (01:35:27 GMT) into an 780 km sun-synchronous, 98 degree inclined orbit.

It carried a Digital Store and Forward packet communications transponder similar to AO-16. Downlink was AX.25 at 437.125 MHz SSB 1200 bps RC-BPSK. It is box shaped with dimensions of 213 × 230 × 230 mm, with four solar panels and weighs 13.76 kg.

Long past its expected useful life, in recent years LUSAT has only been transmitting an unmodulated carrier signal.

On June 29, Gustavo Carpignano, LW2DTZ, reported that recent observers had failed to detect the carrier. Gustavo declared LO-19 dead.

However, on July 1, Nico Janssen, PAØDLO, reported receiving the carrier, but at a signal strength much weaker than over previous years. Nico suggested that, perhaps, the onboard power amplifier has failed.

Well-equipped ground stations may wish to give a listen to test what they can hear.

LEGO Bricks Printed out of Space Dust

There have been many proposals for building structures on the Moon out of lunar regolith. But here’s an idea sure to resonate with creators, mechanical tinkerers, model builders and the kid inside us all.

What about using actual LEGO bricks?

Researchers ground up a 4.5-billion-year-old meteorite and used the dust to 3D print LEGO-style space bricks. They actually click together like the plastic variety, with so far only one downside: they only come in one color, grey.
Universe Today

Want to see some of these lunar LEGOs? LEGO will showcase the space bricks at some of its stores.

Creating building materials on the Moon or Mars from the material on hand means construction materials don’t have to be transported from Earth. This would be a huge savings in launch costs because less weight would have to be boosted from Earth.

A group of scientists from ESA (European Space Agency) were inspired by LEGO bricks, and with the advances in 3D printing, had the idea to print space bricks and test how they would work for construction.

The only problem was that except for the Moon rocks brought back by the Apollo astronauts – which are highly guarded for scientific study only — there’s not any lunar regolith available on Earth to experiment with.

But meteorite dust is a close cousin to lunar regolith. The ESA team was able to get a meteorite that was discovered in Northwest Africa in 2000 and is about 4.5 billion years old. It is made of metal grains and chondrules, similar to Moon dust.

Inspired by LEGO, ESA scientists have used dust from a meteorite to 3D-print LEGO-style ‘space bricks’
to test out construction ideas for a future Moon base. Credit: The LEGO Group

They mixed the meteorite dust with a some other things, like a polymer called polylactide and regolith simulant and 3D printed bricks that mimic and behave just like LEGO bricks. While they aren’t smooth like regular LEGO bricks, ESA said the space bricks gave ESA’s space engineers the flexibility to build and test a variety of structures using this new material.

“It’s no secret that real-world scientists and engineers sometimes try out ideas with LEGO bricks,” said Emmet Fletcher, Head of ESA’s Branding and Partnerships Office. “ESA’s space bricks are a great way to inspire young people and show them how play and the power of the imagination have an important role in space science, too.”

“Nobody has built a structure on the Moon, so it was great to have the flexibility to try out all kinds of designs and building techniques with our space bricks,” said . ESA Science Officer Aidan Cowley. “It was both fun and useful in scientifically understanding the boundaries of these techniques.”

For a list of where the lunar LEGOs will be on display worldwide, see https://www.universetoday.com/167675/lego-bricks-printed-out-of-space-dust/#more-167675

The LEGO website has additional details at https://www.lego.com/en-us/aboutus/news/2024/june/lego-bricks-scientists-build-astronaut-shelters-on-the-moon

Hopefully the lunar LEGOs will inspire both children and adults about space and to encourage them to build their own LEGO Moon bases.

Changes to AMSAT-NA TLE Distribution for July 5

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/.

The following satellites from last week’s Firefly Alpha FLTA005/NASA ELaNa 43 launch have been added. They are listed as OBJECT A-H, with the exception of object G which is likely MESAT1.   As is the case with most cubesat  launches, it will take a while to figure out which object is which.

OBJECT A 60203
OBJECT B 60204
OBJECT C 60205
OBJECT D 60206
OBJECT E 60207
OBJECT F 60208
MESAT1     60209
OBJECT H 60210
OBJECT J 60211
OBJECT K 60212

ARISS NEWS

Amateurs and others around the world may listen in on contacts between amateurs operating in schools and allowing students to interact with astronauts and cosmonauts aboard the International Space Station. The downlink frequency on which to listen is 145.800 MHz worldwide.

UPCOMING CONTACTS:
Youth On the Air 2024, Mount Saint Vincent University, NS, Canada, Telebridge via ZS6JON
The ISS callsign is presently scheduled to be NA1SS
The scheduled crewmember is Jeanette Epps, KF5QNU
The ARISS mentor is VE3TBD
Contact is go for: Tue 2024-07-09 15:06:38 UTC 65 degrees maximum elevation

Houjoudu Elementary School, Imizu, Japan, direct via JA9YQJ
The ISS callsign is presently scheduled to be OR4ISS
The scheduled crewmember is Mike Barratt, KD5MIJ
The ARISS mentor is 7M3TJZ
Contact is go for: Thu 2024-07-11 10:48:03 UTC 83 degrees

The crossband repeater continues to be active (145.990 MHz up {PL 67} & 437.800 MHz down). If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know.

The packet system is also active (145.825 MHz up & down). HamTV (2.395 GHz) and SSTV (145.80 MHz) are both stowed.

As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol.

Note, all times are approximate. It is recommended that you do your own orbital prediction or start listening about 10 minutes before the listed time.

The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html

Upcoming Satellite Operations

NDØC and family will be on another family camping vacation from 24 June thru 7 July, this time through Wisconsin to Michigan and back thru Illinois and Iowa. No super rare grids but several that may be needed by many. The grids and passes will depend on where/when we happen to be while on the road or camping. This will be all LEO sats: FM & SSB. As always, they will try for EU passes on RS-44 when possible. Randy is looking forward to pushing past the 100 grids-roved milestone.

A growing number of satellite rovers are currently engaged in sharing their grid square activations on https://hams.at. By visiting the website, you gain easy access to comprehensive information about the operators responsible for activating specific grid squares. Additionally, you have the ability to assess the match score between yourself and a particular rover for a given pass, while also being able to identify the upcoming satellite passes that are accessible from your location.

Satellite Shorts From All Over

+ What GOES up … NOAA’s latest Geostationary Operational Environmental Satellite, GOES-U, launched on the first Falcon Heavy of the year on June 25 from Launch Complex 39A at Kennedy Space Center. The mission, the last of the GOES-R series of geostationary weather satellites, continuously monitors weather systems over the Western Hemisphere. Assuming that next week’s planned burn to lift the satellite to geosynchronous orbit is successful, this satellite will be re-designated as GOES-19 and will, in coming months, take over the GOES-East duties from the aging GOES-16. (See ANS 182 last week for more details.)

+ Musk come down … Elon Musk’s SpaceX has won a contract valued at up to $843 million to build a vehicle capable of safely deorbiting the International Space Station once the station is decommissioned in 2030. While many people have suggested raising the ISS’s orbit and turning it into a museum, the amount of fuel needed to move the approximately 420-ton station to a high enough orbit to remain stable for long durations is prohibitive.

+ Blow up … Russian Resurs-P1, an almost-six-ton defunct Earth observation satellite that stopped orbit maintenance in 2017 but continued operations until 2022, unexpectedly exploded last week into hundreds of fragments. Expected to reenter later this year, Resurs-P1 was orbiting at ~350 km, close enough to the ISS’s orbital altitude that the event forced ISS astronauts into shelter for an hour while debris was tracked.

+ Or go up, come down, and blow up (unexpectedly) … during a static fire test of the first stage of China’s close-to-finished Tianlong-3 rocket, the hold-down hardware failed to do its singular job: hold down the rocket. Moments after ignition, the rocket shot 1.5 km into the sky above the city of Gongyi, China. With no guidance system, gravity took over, resulting in a massive fireball on impact. Very fortunately, there were no casualties as the rocket mostly went straight up and straight back down.
