ISRO Successfully Launches SSLV-D3, Deploys EOS-08 and SR-0 Demosat

The Indian Space Research Organisation (ISRO) successfully launched its third and final developmental flight of the Small Satellite Launch Vehicle (SSLV-D3) on August 16, 2024. The launch, conducted from the Satish Dhawan Space Centre in Sriharikota, India, placed two satellites, EOS-08 and SR-0 Demosat, into orbit, marking the completion of the SSLV’s development phase. This achievement enables the rocket’s operational use by Indian industry and NewSpace India Limited (NSIL).

The primary payload, EOS-08, is an Earth observation satellite developed by ISRO’s U R Rao Satellite Centre. The satellite was placed into a 475-kilometer low Earth orbit about 13 minutes after liftoff. EOS-08 is equipped with three advanced payloads: the Electro Optical Infrared Payload (EOIR), the Global Navigation Satellite System-Reflectometry payload (GNSS-R), and a SiC UV Dosimeter. These instruments will support a variety of Earth and atmospheric monitoring tasks, including disaster management and environmental surveillance. EOS-08 also features several new technologies, including an integrated avionics system and flexible solar panels, which will be demonstrated during its mission.

SpaceX Transporter-11 Launches 116 Satellites, Including OreSat0.5

SpaceX successfully launched 116 payloads aboard its Falcon 9 rocket as part of the Transporter-11 rideshare mission on August 16, 2024. The launch occurred at 11:56 a.m. PDT from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Base in California. This mission is the latest in SpaceX’s series of rideshare launches, which provide small satellites from various countries an opportunity to reach orbit without needing dedicated launch vehicles. Following stage separation, the Falcon 9’s first-stage booster successfully returned to Landing Zone 4, marking its 12th flight and 20th landing at LZ-4.

Transporter-11 carried a diverse range of payloads, including satellites from Japan, Chile, the United Kingdom, and Australia. Among the Australian payloads were three satellites launched by the Australian Space Agency: Kanyini, Waratah Seed-1, and Cuava-2. Waratah Seed-1, a 6U CubeSat, hosted multiple payloads, such as the Perovskites in Orbit Readiness Test (PORT-2), the Submillimeter Particle Detection System (SPaDeS), and Spiral Blue Space Edge-1 (SE-1), showcasing the collaborative nature of this mission.

Oregon also had a key payload on Transporter-11 with the launch of OreSat0.5, the state’s second satellite. Developed by the Portland State Aerospace Society (PSAS) at Portland State University, OreSat0.5 is a 2U CubeSat designed to demonstrate two critical systems: the attitude determination and control system (ADCS) of the modular OreSat bus and the Cirrus Flux Camera (CFC), which uses short-wave infrared (SWIR) technology. Deployed into a 510 km sun-synchronous low Earth orbit, the satellite began transmitting its first data beacons just 16 minutes after deployment, marking a significant milestone for the Portland State Aerospace Society team.

OreSat0.5’s mission includes testing an open-source ADCS designed for precise antenna and camera pointing on amateur radio satellites, and demonstrating the “DxWiFi” S-band 802.11b bidirectional radio system for high-speed (1 Mbps) communication. Additionally, it aims to provide openly published flight performance data, including power and thermal characteristics, to support the development of cost-effective, scalable satellite systems. Telemetry data from OreSat0.5 can be received on 436.500 MHz and decoded using 9600 baud GMSK with DK3WN’s GetKISS+ v.1.4.2 software. The telemetry dashboard is viewable on the SatNOGS website: https://db.satnogs.org/satellite/DKCD-1609-0567-7056-3922.

Planet Labs PBC, a California-based company, contributed 36 SuperDove Earth-imaging satellites to the mission, along with the Tanager-1 hyperspectral satellite. Tanager-1, developed in collaboration with the Carbon Mapper Coalition and NASA’s Jet Propulsion Laboratory, is designed to detect methane and CO2 emissions from space. This capability will enable precise monitoring of emissions from individual facilities, such as gas pipelines and coal mines, thereby enhancing efforts to combat climate change.

The mission also marked a significant achievement for Exolaunch, the satellite deployment company responsible for integrating 42 of the 116 satellites on the Transporter-11 mission. This launch was Exolaunch’s 30th successful integration, representing more than two dozen companies. Exolaunch CEO Robert Sproles expressed gratitude to their customers and SpaceX, emphasizing the importance of collaboration and innovation in the success of these missions.

Polaris Dawn Set for Historic Launch and First Commercial Spacewalk

The private astronaut mission Polaris Dawn is poised for launch on August 27, 2024, with a groundbreaking objective: the first commercial spacewalk. The four-member crew, consisting of Anna Menon, Scott Poteet, Jared Isaacman, and Sarah Gillis, arrived at the Kennedy Space Center on August 19 to finalize preparations. This mission, the first of the Polaris program, marks a significant step in commercial space exploration and is set to launch aboard a SpaceX Crew Dragon atop a Falcon 9 rocket from Launch Complex 39A.

Scheduled to last five days, the Polaris Dawn mission will propel the Crew Dragon spacecraft to altitudes reaching 1,400 kilometers, the highest for a crewed mission since Apollo 17 in 1972. The mission’s objectives are multifaceted, including testing laser intersatellite links with SpaceX’s Starlink satellites and conducting 40 experiments. However, the highlight will be the spacewalk, a historic first for a private mission, and the first from a Crew Dragon spacecraft. The spacewalk will involve all four astronauts, with two emerging from the hatch in new SpaceX-developed extravehicular activity (EVA) suits for a brief yet pivotal two-hour spacewalk.

Jared Isaacman, the billionaire backing the Polaris program and commander of Polaris Dawn, emphasized the importance of the spacewalk during a press conference after arriving at KSC. “The idea is to learn as much as we possibly can about this suit and get it back to the engineers to inform future suit design evolutions,” Isaacman stated. The spacewalk is scheduled for flight day three, with preparations beginning shortly after launch. The crew will undergo a prebreathing protocol to adjust the cabin’s atmospheric pressure and increase oxygen levels, a process essential for the EVA.

SpaceX engineer Sarah Gillis, serving as a mission specialist, detailed the crew’s rigorous preparations. On flight day two, the astronauts will don the EVA suits for mobility tests inside the spacecraft. During the spacewalk, two astronauts, referred to as EV1 and EV2, will take turns exiting the spacecraft for approximately 15 to 20 minutes each. Isaacman noted that while the idea of a free-floating spacewalk was considered, the crew will instead perform a “hands-free” demonstration with their feet securely attached to the spacecraft’s mobility aids, underscoring the mission’s cautious approach.

The mission’s development has been intensely focused on the spacewalk and the associated EVA suits. “The EVA probably makes up the majority of the development for Polaris Dawn,” Isaacman said, acknowledging the inherent risks. SpaceX vice president Bill Gerstenmaier, formerly of NASA, confirmed that extensive safety protocols have been implemented. He mentioned a recent issue where engineers identified and resolved a static electric discharge risk, ensuring the crew’s safety during the spacewalk.

Polaris Dawn’s mission profile includes a launch window between 3:38 and 7:38 a.m. Eastern on August 27, carefully chosen to minimize risks from micrometeoroids and orbital debris. After reaching an initial orbit, the spacecraft will ascend to 1,400 kilometers before lowering to 700 kilometers for the spacewalk. The mission will conclude with a demonstration of Starlink capabilities on flight day four, followed by reentry on day six. As the first of three planned missions under the Polaris program, Polaris Dawn represents a significant leap forward in commercial spaceflight, setting the stage for future endeavors, including a potential crewed Starship launch.

Satellite Shorts From All Over

+ Russia successfully launched its 89th Progress cargo spacecraft, Progress MS-28, to the International Space Station (ISS) on August 15, 2024. The uncrewed spacecraft lifted off from the Baikonur Cosmodrome in Kazakhstan aboard a Soyuz rocket at 0320 UTC. Carrying nearly three tons of food, scientific equipment, and other supplies, the spacecraft autonomously docked with the ISS on August 17 at 0553 UTC, connecting to the rear port of the Zvezda service module. This docking occurred just days after the previous cargo spacecraft, Progress MS-26, was deorbited on August 12 following its six-month mission. With its arrival, Progress MS-28 joined two other freighters, including Cygnus NG-21, and three crewed spacecraft already at the ISS. The successful mission continues Russia’s long-standing contribution to ISS resupply operations. (ANS thanks Mike Wall, Space.com, for the above information)

+ The European Space Agency’s Jupiter Icy Moons Explorer (Juice) mission is making headlines with its dual gravity assist maneuver this week. After a successful flyby of the moon on August 19, 2024, Juice passed Earth on August 20, 2024, marking the first-ever lunar-Earth double flyby. This maneuver uses Earth’s gravity to adjust Juice’s trajectory, setting it up for a flyby of Venus in August 2025 and ultimately aiming for Jupiter’s orbit by July 2031. The spacecraft’s two cameras are capturing and sending images back to Earth, while mission operators are closely monitoring the high-risk maneuver to ensure precision. With Jupiter being nearly 500 million miles away, this gravity assist strategy allows Juice to conserve fuel and carry a variety of scientific instruments. The mission’s success relies on careful navigation and timing, as any deviation could jeopardize its ambitious goals. (ANS thanks Ashley Strickland, CNN, for the above information).

+ Space is hard: NASA’s BurstCube, which deployed from the ISS in April, is a 6U CubeSat that detects gamma rays from short gamma-ray bursts, likely caused by neutron star collisions. BurstSat, unfortunately, lost one of its magnetorquers during commissioning, along with one solar panel that did not fully deploy. The team has been able to continue the satellite’s mission by compensating for the malfunctioning equipment through the use of a Sun-pointing configuration. But due to these failures, the mission will likely reenter sooner than expected, around the end of 2024. [Before complaining about the failure of your favorite HamSat, consider that even NASA has issues!] (ANS thanks The Orbital Index for the above information.)

+ The FCC has granted SpaceX permission to upgrade its first-generation Starlink satellites with second-generation technology, aiming to enhance broadband quality for its users. This upgrade is expected to improve service, especially in polar regions, by using advanced beam-forming and digital processing technologies. SpaceX initially launched first-generation satellites in 2019 and applied in 2023 to integrate the new technology. Despite pushback from Dish Network over potential interference issues, the FCC dismissed these concerns, supporting SpaceX’s plans to optimize spectrum use and increase network capacity. SpaceX will replace the older satellites with upgraded ones as they reach the end of their operational period, rather than de-orbiting them rapidly. The overall goal is to provide more robust service to underserved areas across the country. (ANS thanks Michael Kan, PCMag, for the above information).

ROBUSTA-3A in Orbit

When the long-delayed inaugural launch of the European Space Agency’s (ESA’s) new Ariane 6 rocket finally occurred on July 7, it suffered an upper stage failure that left some payloads in the wrong orbits. Fortunately, before the anomaly developed, the Ariane 6 successfully deployed ROBUSTA-3A, a satellite with an amateur radio payload. The target was a 580 km circular orbit with an inclination of 96 degrees.

ROBUSTA-3A (a.k.a. “Méditerranée”) is a 3U cubesat, designed and built by students and faculty of Université de Montpellier in southern France. Over a decade in development, involving around 300 students from the University of Montpellier and all over the world, ROBUSTA-3A will be its seventh satellite developed entirely in-house, having learned much from the development and launch of smaller ROBUSTA-1U satellites. The project has offered hands-on training, engineering and scientific experience to the next generation of space engineers and researchers.

The satellite’s primary mission is weather observation, specifically to track “Cevenol events.” These are intense storms and incredibly heavy rains that cause extensive flooding, often in the form of flash floods, that hit the plains and the foothills of southern France. Once considered “100-year storms,” they have been occurring with greater frequency due to global climate change. Most of the weather data is downlinked on a commercial S-band microwave frequency.

“If the data we will be collecting improves the geographic and temporal accuracy of weather forecasts for cévenol events, it would help authorities give early warning to the population and allow rescue services to better target the areas at risk,” explains Romain Briand, assembly integration and testing manager at the University Space Center of Montpellier.

Robusta-3A under development by Centre Spatial Universitaire de Montpellier (CSUM)

However, ROBUSTA-3A aims to do even more than chart water vapour from space.

The satellite carries an experimental Attitude Determination and Control System (ADCS) that will seek to optimize solar panel exposure and correctly aim sensors and microwave downlink antennas. Using a set of Sun sensors, magnetometers, and reaction wheels in a pyramidal configuration, the system should provide precise attitude control, especially during orbital maneuvers.

The satellite will also employ a cold gas thruster propulsion system which operates with solid iodine as propellant. This system will demonstrate orbit maintenance, phasing, and lifetime extension of small satellite missions, and could also help with end-of-life decommissioning and debris mitigation.

As an extra mission, the CubeSat will test how computer memory from chip manufacturer 3D PLUS withstands the radiation of space. This French company specialises in highly-reliable electronic components and their computer memory recently landed on the Moon as part of the India’s Chandrayaan-3 lander.

Finally, ROBUSTA-3A also carries a 9k6 GMSK AX.25 store-and-forward digital system with a UHF transmitter output of up to three watts — a very powerful downlink! As the satellite is sill in commissioning, operating protocols and uplink frequency have not yet been released. However, amateurs should expect something similar to the FalconSAT-3 store-and-forward system that was popular until that satellite deorbited in January of 2023. ROBUSTA-3A is currently transmitting short telemetry bursts on its International Amateur Radio Union (IARU) coordinated downlink frequency of 436.750 MHz.

SONATE-2 APRS Digipeater in Operation

Professor Hakan Kayal from Julius-Maximilians-Universität (JMU) Würzburg in Bavaria, Germany posted on X this past week, “Thanks to everyone using SONATE-2’s APRS digipeater over the weekend. A total of 421 messages were digipeated.”

The Bayerische Julius-Maximilians-Universität Würzburg’s SONATE (SOlutus NAno satelliTE) satellite is a technology demonstration mission for highly autonomous payloads and artificial intelligence in the 6U CubeSat class. As part of the SONATE-2 mission, novel hardware and software technologies of artificial intelligence (AI) are to be verified in miniaturized format in earth orbit. By using such AI technologies, the satellite can independently analyze the environment and start autonomous recordings. Deep learning plays a special role as a versatile image processing tool. In addition to the classification of targets already known at the start of the mission, the payload should also have the option of on-board training for the detection of anomalies as previously unknown objects or phenomena.

The operation of an amateur radio payload is important to the educational mission of SONATE-2. The development and operation of the satellite is used for the education of students of the university. In cooperation with the DLR School Lab in Neustrelitz, Germany, it is planned to use the amateur radio payload for the education of high school students.

The amateur payload of SONATE-2 consists of a VHF transceiver that was already built for the predecessor mission SONATE over the course of several student projects. For SONATE-2 additional student projects extended the transceiver functionalities. It will provide regular SSTV downlinks with images from the optical sensors included in the AI payload as well as an APRS digipeater and CW beacon.

On the education side, the mission will serve as a foundation for different aspects of the university aerospace and computer science engineering program. In the context of practical courses, as thesis authors or as student assistants, students can participate in the development of all subsystems of the space and ground segment, including the amateur radio payload and the technology demonstration payload. In the context of mandatory lectures and exercises on space operations every student will also be included in the operations of the satellite.

The German Aerospace Center (DLR) offers a School Lab for high school students at the location of the external ground station in Neustrelitz, Germany. Besides experiments on space and satellites, the School Lab includes amateur radio contacts to the ISS under the supervision of licensed local radio amateurs, which they wish to extend to other satellites like in this cooperation with the SONATE-2 mission.

Besides the amateur and educational mission parts, the SONATE-2 mission also has a research objective for the demonstration of novel artificial intelligence technology in the space environments. While the AI payload is mainly operated using a separate up/downlink in the space operation service in S-band, the satellite bus and the amateur payloads are operated in the amateur service. Housekeeping telemetry in the amateur service also contains status information of the non-amateur payload.

According to Kayal, not many similar projects are currently being undertaken.

“Let’s assume that a small satellite is to investigate a new asteroid in the solar system in the future. It cannot be trained for this task on the ground, because the object of investigation is largely unknown. There is no training data, so the measurements and recordings can’t be made on the ground,” Kayal added.

Transmitting this data to Earth for initial processing and subsequently training the AI via remote control would result in significant time delays for missions located at a considerable distance from Earth.

Opting for a heightened level of autonomy with direct on-board AI support would greatly enhance the mission’s efficiency. This approach would expedite the detection of intriguing objects and phenomena on the asteroid, considerably reducing the time required for their identification.

To facilitate this, four on-board cameras capture the essential imagery required for training the AI. Initially, the AI acquires knowledge of conventional geometric patterns on Earth’s surface, among other things, which subsequently empowers it to autonomously identify anomalies.

In addition to these AI experiments, SONATE-2 carries a suite of other small satellite technologies that are ready for in-orbit testing. These technologies include an automated lightning detection and recording system, as well as an electric propulsion system developed in collaboration with the University of Stuttgart.

Kayal added, “In terms of complexity, SONATE-2 is unparalleled among nanosatellites.”

Wireless Technology Workshop in India

A special workshop on ‘Wireless Technology and its Practical Solutions’ was conducted for Rajkot – Police Wireless Department at Gujarat (India) on 20th July 2024. The venue was the Police Training Center at Rajkot Headquarter. It was a highly informative 3 hours session from 10:00 AM to 1:00 PM.

Regional Coordinator of AMSAT-INDIA & The Amateur Radio Society of India, Mr. Rajesh Vagadia, VU2EXP, gave insight into various Radio Communication protocols, types of modulation, modes & various applications used in Amateur Radio & Police department.

Rajesh Vagadia, VU2EXP (hamphotos.com)

As this workshop was targeted for 25 technical wireless officers & radio operators, we focused on the radio communication enhancing methods, utilizing various techniques, using different antennas for specific applications and diagnosis of wireless setup with various measuring instruments incl. SWR/Power Meter, NanoVNA/Antenna Analyzer. We extended a handful of maintenance tips for Radio, Antenna, Feed line & repeaters to optimize radio communications.

We also gave an overview of Ham Radio & its various events, Understanding of Digital Communication, Satellite Communication, Features of newer Digital protocol incl. DMR, D-STAR & Fusion. There was good interaction with participants, lots of doubt & queries were cleared satisfactorily. Good number of radio stuff was displayed incl. HTs, VHF Base Radio, IC-705 SDR HF Radio, RTL SDR Dongle, Antenna Tuner, CAT Control, Soundcard Interface, Morse Key, CW Paddle & Keyer, CubeSat model, Balun, LNA, SWR/Power meter, NanoVNA, Dummy load, PSU, Feed lines, EFHW Antenna, Telescopic Antenna, Connectors, Adaptors, ARISS Awards, QSL Cards etc., which helped participants to view, discuss & understand our entire stuff better.

We always give practical demos, but, here in the audience was a heavy user of CW & RT from the police dept. We didn’t give a demo of that kind hi..hi.., but surely gave demos of Digital Communication – sending text messages between two VHF Setup and a second demo of sending SSTV Images between two local vhf stations! For the audience it was interesting to learn how we ham convert simple ASCII codes to corresponding audio frequencies (for Digital Communication) and RGB pixel values of Image to Slow Scan Television format to transmit & receive ‘IMAGES’ via our standard radios! That’s why we proudly call Ham Radio the oldest Social Media!

It was a nice & fruitful workshop overall. I am thankful to Commissioner of Police Rajkot Shri Brajesh Kumar Jha Sir for approval of this workshop and Shri S K Jadeja Sir (PI Wireless) for nicely coordinating this workshop. I am thankful to our AMSAT-INDIA & ARSI (The Amateur Radio Society of India) for their great support and guidance to make this workshop highly successful.

We wish Rajkot Gujarat Police will utilize the gained knowledge & implement into the system for better productivity!

Small Satellites of the Future Grow Larger

Small satellite companies that have grown out of the New Space boom are retiring the cubesat platforms that made them to focus on larger, more powerful next-get small sats that promise to unlock new possibilities with advanced AI and real-time laser-based inter-satellite communications.

Over the past 15 years, small satellites have revolutionized how things are done in space. Built quickly from cheap, off-the-shelf components, and small enough to hitch an affordable ride to orbit on the back of bigger missions, these devices and the young, agile New Space companies behind them taught the old-school space industry a few lessons.

But New Space is coming of age and the firms behind the small satellite revolution must live up to expectations less favorable to their trade-mark experimental ethos. The lowest cost and shortest time to orbit may no longer be the technology’s biggest draw as users want maximum return on investment and require granted reliability. The firms behind the disruptive tech, however, have grown up together with their market share and are tapping into emerging innovation, looking to unleash a whole load of new applications in the coming years.
The Evolution of the Smallsat

Satellites started small. The first U.S. satellite, Explorer 1 — launched in 1958 — weighed only 14 kilograms. But the technology, prized for opening a whole new perspective on our planet, quickly bulked up, enabled by the increasing lifting powers of fast-evolving rockets. Soon, complex satellites the size of a school bus took over, observing the planet from above, broadcasting TV signals across continents and sensing the environment around them.

It was only in the mid-1980s that researchers renewed their interest in smaller satellites with masses of tens to a couple of hundred kilograms. The true small sat revolution, however, began in 1999, with the invention of a cubesat. Based on standardized satellite units of 10 by 10 by 10 centimeters in size, cubesats opened space to anyone with enough technical skill to assemble and operate them. Soon, university teams from all over the world began launching their own experimental spacecraft to provide their students with hands-on space tech experience.

By 2014, San Francisco-based Planet Labs launched its first commercial constellation of 28 three-unit (3U) Earth-observing cubesats called Doves. More than 120 Doves are in orbit today, capturing an image of each place on Earth more than once a day. Other companies followed suit. As of today, cubesats have made it to orbit around Mars and the Moon and observed the impact of NASA’s Double Asteroid Redirection Test (DART) into the asteroid Didymos in 2022 in real-time.

Larger small satellite platforms — up to 500 kg in mass — have also grown in popularity. In fact, these larger small satellites today dominate space around Earth thanks to SpaceX’s constellation of Starlink internet-beaming satellites.

Consulting firm Novaspace predicts that 26,104 small satellites — including minisatellites of 100 to 500 kg in mass, microsatellites between 10 and 100 kg and nanosatellites as light as 1 to 10 kg — will launch in the next decade.

And although the smallsat revolution is already behind us, new technologies are emerging that promise to supercharge the sector in the coming years. Via Satellite spoke with a number of experts in the field about what the smallsat of the future will look like.

ASRTU-1 Scheduled for November Launch

Published flight manifests indicate that the Chinese amateur radio satellite ASRTU-1 has been scheduled for launch in November of this year aboard a Russian rocket. As always, launches are subject to a wide variety of variables, and space agencies are not always 100% forthcoming about their activities. So while you may not want to mark the calendar just yet, hopeful signs are pointing toward a launch in the coming months.

Artist’s sketch of ASRTU-1

ASRTU-1 is a 12U Cubesat mission designed by Russian and Chinese university students for education and amateur radio. Harbin Institute of Technology has successfully developed several amateur radio satellites, including LilacSat-2 (CAS-3H), LilacSat-1 (LO-90), DSLWP-A (LO-93) and DSLWP-B (LO-94). The partner institution is Bauman Moscow State Technical University, which constructed two satellites, Baumanets-1 in 2006 and Baumanets-2 in 2017, both of which unfortunately failed to reach orbit due to launch failures unrelated to the satellite payloads.

The amateur radio station onboard ASRTU-1 will provide FM and telecommand uplinks, as well as FM, telemetry, and digital image downlinks. A new SDR based transceiver was developed to provide communication and experimental resources to radio amateurs, including a V/U FM transponder, a UHF telemetry downlink, and a 10.5G image downlink.

The repeater uplink will be on 145.875 MHz FM using a 67 Hz CTCSS (PL) tone. Downlink will be on 435.400 MHz FM. The telemetry beacon will be on 436.210 MHz using 9k6 bps BPSK.

In addition to the FM repeater, the satellite will also provide an open telecommand system to allow radio amateurs to send commands to control the satellite to take and download images. X Band image downloads using 1 Mbps/10mbps QSPK will downlink on 10.460 GHz.

ASRTU-1 has been scheduled for a Roscosmos launch from Vostochny Cosmodrome, Asiatic Russia, in Q4 2024 into a 530 km Sun-synchronous Orbit (SSO). Downlinks and the repeater uplink have been coordinated by the International Amateur Radio Union (IARU).

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)

ANS-189 AMSAT News Service Weekly Bulletins

DATE 2024 July 7

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.

KUbeSat-1, revives small satellite research at the University of Kansas and starts a new KUbeSat program that will offer space access to student research. The main payload on KUbeSat-1 is the Primary Cosmic Ray Detector which will use a new method to measure the energy and species of primary cosmic rays hitting the Earth. The secondary payload is the High-Altitude Calibration, (HiCalK) that builds on decades of research surrounding Very High Frequency signals generated by cosmic ray interactions with the atmosphere. UHF downlink using 9k6 GMSK. A downlink on 437.085 MHz.

SOC-i (Satellite for Optimal Control and Imaging) is a technology demonstration mission of attitude control technology and a camera that serves as an instrument to demonstrate SOC-i’s pointing abilities. Developed at the University of Washington, SOC-i has a UHF downlink using 4k8 GMSK. downlink 437.125 MHz.

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.

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.

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.
