    AMSAT’s GOLF-TEE CubeSat de-manifested from launch on ELaNa-46

    NASA has de-manifested GOLF-TEE from the ELaNa-46 mission at the request of AMSAT. ELaNa-46 was expected to launch no earlier than 2022. COVID-related restrictions and supply chain disruptions, affecting both AMSAT’s vendors
    and team, have put AMSAT’s ability to meet the mission integration timeli
    at high risk.

    AMSAT Vice-President Engineering Jerry Buxton, N0JY, described some of the reasons for this decision:
    • AMSAT finds itself in a similar situation to what other payloads and space-industry providers are experiencing. The worldwide pandemic and
    supply chain shortages are threatening everyone’s ability to properly and successfully deliver for launches.
    • Out of respect for NASA, the launch provider, and other payloads, it
    is important to withdraw now, rather than later or, even worst, missing a launch integration deadline, which has possible financial penalty
    • GOLF-TEE and GOLF-1 have both been selected to participate in NASA’s CubeSat Launch Initiative program, and NASA will continue to look for
    another launch for GOLF-TEE.

    AMSAT’s GOLF program plays an important role in AMSAT’s return to highly elliptical orbits. In addition to proving the maneuverability capabilities required by current and proposed orbital debris regulations, the GOLF
    program will work through a series of increasingly capable spacecraft to develop skills and learn systems for which we do not yet have the necessary low-risk experience. Among these are active attitude control, deployable/steerable solar panels, radiation tolerance for Commercial off
    the Shelf (COTS) components in higher orbits, and propulsion.

    The TEE designation in GOLF-TEE stands for “Technology Exploration
    Environment” and reflects GOLF-TEE’s mission goal to test two critical
    systems needed for higher orbits. The first is an Attitude Determination and Control System (ADCS) that will allow active pointing of high gain satellite antennas, provide accurate attitude adjustments in future missions with maneuverability systems, and allow pointing the fixed solar panel array for best solar power in any given orbit type. The second is the
    Radiation-Tolerant Integrated Housekeeping Unit (RTIHU), which will allow
    AMSAT to gain initial orbit and space radiation exposure for radiation event-induced fault tolerant systems designed using COTS components.
    GOLF-TEE’s RTIHU includes a command transceiver, and its design is based
    the Hercules line of ARM architecture-based microcontrollers.

    GOLF-TEE will also evaluate a low-cost, deployable, fixed attitude, solar
    panel array design as part of AMSAT Engineering’s exploration of fixed pa
    arrays that allow for outfitting a variable number of “wings” in order
    best match the power requirements of various CubeSat missions.

    Additionally, GOLF-TEE will carry a modified Ettus E310 commercial software-defined radio (SDR), as an experimental package, to test the high speed data downlink in the 10 GHz band and a parrot V/x mode linear
    transponder to provide users with an opportunity to experiment with the 10
    GHz microwave downlink. GOLF-TEE will also carry a legacy V/u linear transponder.

    GOLF-1 will build on technology and lessons learned from the GOLF-TEE
    mission; however, it will be a return to STEM-based educational missions, including hosted student radiation and imaging experiments in collaboration with AMSAT’s educational partners. GOLF-1 will require a more comprehens
    de-orbiting plan and hardware that are in compliance with NASA’s NPR 8715
    NASA Procedural Requirements for Limiting Orbital Debris in order to be manifested on an ELaNa launch to the high altitude AMSAT is seeking.

    A significant amount of funding is necessary to complete the development and construction of the GOLF series of CubeSats. Please consider a donation

    Weak Signals Heard from Spanish Satellites EASAT-2 and HADES

    AMSAT-EA (Spain) has said it appears that EASAT-2 and HADES are
    transmitting, and that weak signals have been heard, but the satellites’ antennas may not have deployed.

    “We confirm the reception of both EASAT-2 and HADES, as well as the decod
    of telemetry and the FM recorded voice beacon with the call sign AM5SAT of
    the first one. EASAT-2 appears to be working well, except for the deployment
    of the antennas — something that apparently has not yet occurred and caus
    weak signals,” said AMSAT-EA Mission Manager Felix Paez, EA4GQS. “Howev
    the AMSAT-EA team confirms that, based on the reception of FSK, CW, the FM voice beacon, and the telemetry data that has been decoded, it can be said
    that the satellite is working perfectly. In the event of low battery or
    system malfunction, the onboard computer would not transmit CW messages or
    the voice beacon call sign, as it would be in [safe mode] with only fast and slow telemetry transmissions.”

    At the request of AMSAT-EA, EASAT-2 has been designated as Spain-OSCAR 114 (SO-114) and HADES as Spain-OSCAR 115 (SO-115).

    “These signals that confirm the operation of both satellites were received
    by Daniel Estévez, EA4GPZ, at 1807 UTC on Saturday, January 15, using two antennas from the Allen Telescope Array.” Doppler observations from the co-launched Delfi-PQ satellite and the amateur radio community have been
    used to identify the satellites’ orbits or TLEs.

    AMSAT-EA reports that Estévez performed a preliminary analysis using just
    one polarization of one of the Allen Telescope Array satellite dishes.
    EASAT-2 was detected with a relatively strong signal, close to the Delfi-PQ signal, obtaining voice FM beacon transmissions and FSK, FSK-CW at 50 baud, AMSAT-EA said.

    “The CW beacon clearly shows the message VVV AM5SAT SOL Y PLAYA, which is
    one of several that both satellites emit, although the call sign AM5SAT confirms that it is EASAT-2,” AMSAT-EA said. “In the recording made by
    EA4GPZ, there is also a faint trace confirmed to be from HADES and stronger packets probably from the IRIS-A satellite.”

    AMSAT-EA reports that signals from HADES are weaker than those of EASAT-2, “most likely because the onboard computer has not yet managed to deploy t
    antennas either, although it will continue trying regularly,” AMSAT-EA sa
    “The reason the signals are suspected to be weaker at HADES is that the antennas are more tightly folded than those of EASAT-2. In any case, this is great news, since the transmission pattern confirms the proper functioning
    of the satellite. In the observations, you can see the FSK tones with a deviation of about 5 kHz interspersed with the FM carrier corresponding to
    the voice beacon of the satellite, which has call sign AM6SAT. The AMSAT-EA team is working to try to decode the telemetry signals and obtain more
    detailed information on the state of the satellite.”

    AMSAT is asking amateurs with “very high-gain antennas” to try to recei
    them — especially HADES. “If we could decode telemetry, it would be very helpful for us.” AMSAT-EA said. “Until antennas are deployed, it will be
    very difficult to use their repeaters or to receive any SSTV camera images
    from HADES, but we hope that this will happen sooner or later, at least because, even if the computer doesn’t succeed applying heat to the resist
    where the thread [retaining the antennas] is attached, with time, the thread should break due to the space environment conditions.”

    Svalbard QO-100 Satellite DX-Pedition Announced

    The very first Svalbard QO-100 Satellite DX-Pedition will take place April 22-24, 2022 from Kapp Linné – Isfjord Radio at 78° North. ON4CKM Cedr
    ON5UR Max and ON4DCU Patrick will take up the challenge and travel to Kapp Linné and stay there for 3 days, trying to be active 24 hours a day via t
    Qatar-OSCAR 100 satellite. They will operate two QO-100 satellite stations under the callsigns JW0W and JW100QO, while JW0X will be used by another
    team for contacts on shortwave.

    With QO-100 only 3° above the horizon, Kap Linné was the only suitable
    in the area with Svalbard at the edge of the satellite footprint. Looking
    for a suitable location to stay and getting there, is one of the biggest challenges and cost drivers for the team. This is indeed a very unique opportunity to work this rare location and DXCC via satellite. And if they
    are lucky, they might also be able to contact DP0GVN at the german antarctic research Neumayer-Station III for the North/South distance record via
    QO-100. The team is seeking donations. Additional information and graphics

    Orbital Mechanics for New and Experienced Satellite Operators

    Bob Meyers, WA8FXQ posted a useful link he discovered in the most recent Orbital Index. It is particularly good for those who want a better understanding of fundamental behind GPS.

    The link's author, Bartosz Ciechanowski, is a blogger who focuses on explorations of physics, math, and engineering. His animations couple with
    his straight forward explanations to create a clear view of each topic he tackles. His current blog post is focused on the principles behind GPS
    systems, however in the process of explaining how GPS systems work, he
    tackles orbital mechnics and the relationship of orbital altitude to radio footprint of satellites. His excellent animations make it possible for him
    to present the rather complicated mathematics visually and without requiring the viewer to have a strong mathematical background. His blog on the GPS
    system may be seen at: https://ciechanow.ski/gps/. He is also a Patreon
    creator and fields questions and discussions on that platform.

    Satellite Shorts From All Over

    + A Martian carbon biosignature? Not content to be overshadowed by the
    newer, shinier Perseverance, Curiosity has roved and drilled on (for nearly
    10 years now). A paper and NASA summary both report (appropriately conservatively) on tantalizing new evidence from the rover of potential biosignatures in Gale crater. Curiosity’s SAM lab heated 24 different
    powdered rock samples to 850° C, releasing their solid carbon as methane
    gas. The onboard Tunable Laser Spectrometer then measured the carbon
    isotopes in that gas and found more 12C than would be expected based on the 12C-to-13C ratio in the modern Martian atmosphere. On Earth, life preferentially uses 12C over the heavier 13C, bioaccumulating it, so that we observe significantly more 12C than 13C in ancient rocks where life grew.
    Did ancient Martian microbial methanogenesis concentrate this isotope at
    Gale crater as it built up complex organic molecules? Maybe. Two other hypotheses offer abiotic explanations: one suggests that UV light could have caused CO2 in the Martian atmosphere to form isotopically enriched carbon monoxide molecules that settled to the surface, the other wonders if the isotopes arrived from space when our solar system drifted through a 13C-depleted giant molecular cloud hundreds of millions of years ago. It’s
    also possible that the Martian atmospheric concentration changed over time
    for some unknown reason. “On Earth, processes that would produce the carb
    signal we’re detecting on Mars are biological,” but we don’t understa
    nd the
    Martian carbon cycle well enough yet to have any real confidence. As with
    other tantalizing results about microbial extraterrestrial life, this will probably just turn out to be a physicochemical process we don’t yet
    understand. Or maybe not. See https://go.nasa.gov/35vE0IQ and http://bit.ly/3IIKpyF for details. [ANS thanks NASA and The Orbital Index

    + Reaching the tipping point for 3D printing satellites: The number of 3D-printed parts on board satellites is growing amid advances in additive manufacturing. Satellite shops are embracing the technology to cut costs and accelerate production for increasingly capable spacecraft. Advances are
    paving the way to a future where satellites can print parts in orbit. But
    how close is the industry to 3D printing entire satellites? It’s a tricky question, not least because the number of parts on a satellite differs
    greatly depending on its size and complexity, and range from simple foundational structures to intricate semiconductors. “Cubesat parts can
    number in the hundreds of components while larger satellites can range from tens of thousands to hundreds of thousands” for flagship missions such as
    the just-launched $10 billion James Webb Space Telescope, said Emile de
    Rijk, CEO of additive manufacturing specialist Swissto12. But just five
    years ago, the “use of 3D printed structures was largely experimental with
    very few parts being flown in missions and payloads that had a healthy risk appetite,” according to de Rijk. Now, nearly all satellites built today h
    at least some 3D printed parts, he says, although most are still relatively simple mechanical bracketing systems for keeping a spacecraft’s structure together. More information may be found at: https://bit.ly/3g3sWod. [ANS

    + SpaceX rocket on collision course with moon: A rocket launched by Elon
    Musk's space exploration company is on course to crash into the Moon and explode. The Falcon 9 booster was launched in 2015 but after completing its mission, it did not have enough fuel to return towards Earth and instead remained in space. Astronomer Jonathan McDowell told BBC News it will be the first known uncontrolled rocket collision with the Moon, but the effects
    will be minor. The rocket was abandoned in high orbit seven years ago after
    it completed a mission to send a space weather satellite on a million-mile journey. It was part of Elon Musk's space exploration programme SpaceX, a commercial company that ultimately aims to get humans living on other
    planets. See https://bbc.in/3o4bpRa for the full story. [ANS thanks Georgina Rannard of BBC News for the above information]

    + NASA to name astronauts this year for first Artemis moon mission: NASA
    will announce later this year the four astronauts who will slingshot around
    the far side of the moon on the Artemis lunar program’s first crew missio
    currently scheduled for launch in 2024, the head of the agency’s human sp
    exploration division recently said. The crew is expected to include three
    U.S. fliers and one Canadian astronaut. The Artemis 2 mission will follow
    two years after NASA’s Artemis 1 test flight, an unpiloted pathfinder
    mission scheduled to launch no earlier than March from Kennedy Space Center
    in Florida. Artemis 1 will be the first flight of NASA’s Space Launch
    System, a heavy-lift rocket designed for lunar missions that’s been in development for more than a decade. It will also be first trip by NASA’s
    Orion crew capsule to the moon, following a demonstration flight that
    orbited Earth in 2014. The goal of NASA’s Artemis program is to land
    astronauts on the moon’s surface for the first time since the final Apollo lunar mission in December 1972. The Artemis program’s first attempt to la
    a crew on the moon is penciled in for the Artemis 3 mission, scheduled for 2025, with a derivative of the Starship vehicle SpaceX’s is developing in
    South Texas. More info is available at: https://bit.ly/3L0nGQG. [ANS thanks Stephen Clark of Spaceflight Now for the above information]
