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

    AMSAT's AO-109, also known as Fox-1E, has recently achieved a remarkable mi lestone. Launched in January 2021, this satellite operates with an 8 mW sig nal, best suited for CW and FT4 communications among amateur radio enthusia sts. Recent telemetry data from the Dwingeloo Radiotelescope in The Netherl ands has revealed an impressive feat: AO-109 has set a new record for proce ssor uptime. This information was gathered by Alan Biddle, WA4SCA, who has meticulously monitored telemetry reports on a daily basis and calculated th
    e duration of each reset, allowing for precise correlation of telemetry fra
    mes with UTC time.

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

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

    il 2024. [Credit: AMSAT]

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

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

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

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

    In Belgium last week, the European Space Agency revealed the spacecraft pai
    r which constitute the Proba-3 mission. This initiative aims to generate or bital solar eclipses at will, providing researchers with extended periods t
    o scrutinize the Sun's ethereal corona. The mission comprises two spacecraf
    t: the Occulter and the Coronagraph. Positioned approximately 150 meters ap art, these spacecraft will align meticulously with the Sun, with the Occult
    er casting a shadow onto the Coronagraph, effectively blocking out the Sun'
    s glare and unveiling the corona.

    Dietmar Pilz, ESA's Director of Technology, Engineering, and Quality, expla ins, "The two spacecraft will act as if they are one enormous 150-meter-lon
    g instrument." However, achieving such precision poses immense technical ch allenges. Even the slightest misalignment could disrupt the mission's effic acy. Consequently, the development process, spearheaded by a consortium of
    ESA Member States led by Spain and Belgium, has been extensive. [https://www.amsat.org/wordpress/wp-content/uploads/2024/04/Proba-3_Satelli tes_Earth.jpg]<https://www.amsat.org/wordpress/wp-content/uploads/2024/04/P roba-3_Satellites_Earth.jpg>

    t: European Space Agency]

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

    Solar eclipses, a consequence of the fortunate alignment of the Sun and the
    Moon, unveil the solar corona - a region of profound scientific and practi
    cal significance. Significantly hotter than the Sun's surface, the corona i nfluences space weather, solar wind, and phenomena like coronal mass ejecti ons, which can impact satellite operations and terrestrial communications n etworks.

    Proba-3's groundbreaking approach involves orchestrating the Occulter and C oronagraph to operate as a unified entity, thus minimizing diffraction effe
    cts and maximizing the observation of the corona. This collaboration, facil itated by advanced positioning technologies, promises to unveil the mysteri
    es of the corona within the range of 3 to 1.1 solar radii from the Sun.

    [https://www.amsat.org/wordpress/wp-content/uploads/2024/04/Proba-3_Occulte r_Coronagraph_Spacecraft-scaled.jpg]<https://www.amsat.org/wordpress/wp-con tent/uploads/2024/04/Proba-3_Occulter_Coronagraph_Spacecraft-scaled.jpg>

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

    Beyond its scientific implications, the success of Proba-3 could herald a n
    ew era of space missions, facilitating endeavors like in-orbit satellite se rvicing and deploying larger-scale space infrastructure. Moreover, the miss ion's instruments, like ASPIICS and the radiometer, hold promise for climat
    e modeling and advancing our understanding of solar dynamics.

    As the world awaits the North American total solar eclipse, members of Prob a-3's science team seize the opportunity to test mission hardware. Componen
    ts like polarizing filter wheels and alternative LED technologies will unde
    rgo rigorous examination, further refining the mission's capabilities.

    Satellite Shorts From All Over

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

    + The final launch of United Launch Alliance's Delta Heavy IV rocket is sch eduled for April 9, marking the end of a 64-year legacy for the Delta famil
    y. The highly successful career of the Delta Heavy IV comes to a close as i
    t launches a classified payload, NROL-70, on behalf of the U.S. National Re connaissance Office (NRO). The NRO, responsible for the country's surveilla
    nce satellites, maintains secrecy about the specifics of its missions. This
    final launch aims to enhance the NRO's capabilities in providing intellige
    nce to national decision-makers and supporting global humanitarian efforts.
    United Launch Alliance plans to retire both the Delta IV Heavy and the Atl
    as V to pave the way for its new Vulcan Centaur rocket, with the Atlas V sc heduled for missions until 2029. The era of the Delta family concludes amid
    st a transition towards more advanced launch technologies and capabilities.

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

    + China's Queqiao-2 satellite successfully launched from the Wenchang Space
    Launch Site on March 20th, reaching lunar orbit after a perilune braking m aneuver near the Moon's surface on March 24th. Positioned to relay communic ations for future lunar missions, including Chang'e-4 and Chang'e-6, Queqia o-2's orbit will be adjusted to facilitate these missions and support China
    's ambitious lunar exploration program. Accompanying experimental satellite
    s, Tiandu-1 and -2, also entered lunar orbit, conducting tests in communica tion and navigation. Queqiao-2's strategic orbit placement in the Moon's ma
    ria region holds significance for China's lunar exploration history, includ
    ing past probe landings fifteen years ago on March 1, 2009. China's lunar m issions, aiming to scout resources and establish a lunar base, signify a su bstantial endeavor parallel to NASA's Artemis Program, which plans to estab lish a sustained presence on the Moon with international collaboration.
