    OMOTENASHI Project Shoots for the Moon This Week

    OMOTENASHI, a project of the JAXA Ham Radio Club, is a CubeSat which will
    be launched by NASA SLS rocket, scheduled for August 29. It plans to land
    on the surface of the moon, and to transmit a beacon in the amateur 70cm

    OMOTENASHI is one of the EM-1 CubeSat missions which will be launched by
    the NASA/SLS rocket (EM-1) together with the main mission of ORION
    experimental module on Monday. JAXA Ham Radio Club is going to utilize the flight demonstration opportunity of the OMOTENASHI mission to conduct the following amateur radio missions:
    (i) To conduct technological research with respect to receiving ultra-weak
    UHF signal from a space probe toward the moon
    (ii) To conduct an outreach activity providing amateur radio operators all over the world with an opportunity to try to receive signals from moon

    OMOTENASHI is a 6U-CubeSat with external dimensions of 239 x 366 x 113mm
    and an approximate mass of 14 kg.

    OMOTENASHI consists of three modules: orbiting module, retro motor module,
    and surface probe. During the moon transfer orbit, these modules are integrated. When OMOTENASHI arrives at the moon, the surface probe will be separated and conduct semi-hard landing.

    OMOTENASHI is actively controlled by ultra-small attitude control system including star tracker, sun sensor, IMU, reaction wheel, and cold gas jet thruster. During the moon transfer orbit, OMOTENASHI may be spin-stabilized
    due to the strict resources. For further details, please see: https://www.isas.jaxa.jp/home/omotenashi/JHRCweb/jhrc.html

    There will be UHF CM/PSK/PM/PSK31 beacons, with 1 watt RF, on both the
    orbiting module and the surface probe. CisLunar explorer, MIT KitCube and
    Lunar IceCube are expected to share the same launch.

    SLS Launch Party on Discord!

    AMSAT is hosting an event in Discord, https://discord.gg/Duca8jY5?event12703802727608330. It will be in the #watch-party channel for the STS launch carrying Orion to the Moon, along
    with OMOTENASHI (see above) and a number of other small satellites.

    AMSAT plans to start streaming NASA’s YouTube video coverage starti
    ng at
    about 0300Z on Monday, August 29. If that doesn’t work out, people
    always watch it on their own, and just join the channel to chat about the mission. Voice chat, web cams, and text will all be available for people to use.

    The AMSAT Discord server is available for the amateur satellite community. Discord is a text, voice, and video client that has become very popular in recent years. Discord will provide the amateur satellite community with an additional option to communicate amongst each other, in real-time.

    Discord provides several neat features, including the following:

    Launch of GENESIS-G and GENESIS-J with Firefly on September 11

    AMSAT-EA confirms that the launch of our new GENESIS-G and GENESIS-J
    satellites with Firefly will take place, if all goes well, on September 11, with the launch window starting at 3 PM Pacific Time (22h GMT), from Vanderberg. The expected orbit altitude is 300 km with an inclination of
    137 degrees.

    As many of you know, this will be the second attempt of Firefly to reach
    orbit after the first attempt made in September 2021 and which had to be aborted after two minutes of flight, causing our previous GENESIS-N and GENESIS-L to be lost, among others.

    These new GENESIS have a more powerful on-board computer than their predecessors and updated software that allows FM voice repeater
    functionality, AFSK/FSK non-regenerative repeater up to 2400 bps, FSK regenerative repeater up to 50 bps, CW, digitized voice pre-recorded FM and
    FSK telemetry at 50 bps. The correct retransmission of AX25 / APRS frames
    over FM up to 2400 bps has been verified in the laboratory.

    A small drawback we still have is the antenna deployment mechanism, that is
    the first version that was made and requires a plenty charged battery. The satellites have been stored for several months, so it is a weak point. Hopefully it will work.

    These satellites also have the names of ASTROLAND-1 and ASTROLAND-2 to say thanks to the sponsorship of the project by the Astroland Planetary Agency.
    We also thank the private companies and Universities that helped in the project.

    As on the previous occasion, two experimental propellants are flown,
    although this time they are from the Madrid company IENAI Space and, unlike
    the previous GENESIS mission, they use a liquid ionic fuel. Only the one
    from GENESIS-J is functional. The one from GENESIS-G carries the
    electronics but without the fuel.

    The frequencies coordinated with IARU are the following:

    145.875 MHz uplink, Modes: FM voice (no subtone) and FSK 50 bps, AFSK,
    AX.25, APRS 1200 / 2400 bps
    436.888 MHz downlink, Modes: FM voice, CW, FSK 50 bps, FM voice beacon with AM2SAT callsign

    145.925 MHz uplink, Modes: FM voice (no subtone) and FSK 50 bps, AFSK,
    AX.25, APRS 1200 / 2400 bps
    436.666 MHz downlink, Modes: FM voice, CW FSK 50 bps, SSTV Robot 36, FM
    voice beacon with AM3SAT callsign

    We encourage all to try to receive their first transmissions once the first keplerians are available.

    This flight will be streamed by Everyday Astronaut: https://everydayastronaut.com/

    Limited-Time Opportunity - DX on AO27!

    "On" times for AO-27 continue to shift along the direction of the orbit.
    The 5 min "on time" for ascending passes at mid-latitudes is now on
    DESCENDING passes. Based on current SATNOGS observations, from when the satellite is at about 75 degN to about 65 deg N. The descending node
    telemetry and repeater operation is probably only available to stations
    further and further south (a few lucky far-S America and maybe VK and ZL stations may soon be able work Antarctica if anyone is on!).

    Northern Europe and the UK are now well in the footprint, NE Canadian
    provinces and some New England stations may be able to work Europe, and KL7
    may be able to work northern Japan in a few weeks! These opportunities
    won't last - the "on" time will continue to shift, and once the onboard
    clock is reset, the satellite will be back on a "normal" schedule.

    If you hear or work AO-27, the command stations would appreciate knowing precise times for when the transmitter came on or turned off, and the
    reporting station's 6-character grid square or lat/lon. If you are in the
    far South and hear the 20 seconds of telemetry, try to capture KISS frames
    (NOT ASCII) and send the captured data file (or a good audio file we can
    try to decode). If scheduling SATNOGs observations (provides an excellent measure of on and off times), try to schedule descending passes during the
    "on" times and don't bother with ascending passes for now.

    So, You Want To Build A CubeSat?

    Everybody's sure it's easy! Just follow these simple steps:
    + First, select an appropriate CubeSat form factor based on payload size,
    power requirements, and deployment mechanism.
    + Consider power budget (especially for when the spacecraft is “in
    on the dark side of the Earth), acceleration and vibration tolerance (the
    sound of launch alone can damage the spacecraft), and thermal management
    (your satellite is effectively sitting in a rather large vacuum thermos).
    + Use Commercial Off-The-Shelf (COTS) parts with existing flight heritage wherever possible—see satsearch and CubeSatShop.
    + Pick solar panels, batteries, and an Electrical Power System (EPS) to
    manage them.
    + Include one or more antennas and radios to talk to a ground station or
    ground station network (or broadcast up to GlobalStar or Iridium instead).
    + If you need to maintain orientation, include an Attitude Determination
    and Control Systems (ADCS) which will use some combination of Earth, Sun,
    and star trackers, gyroscopes, GPS receivers, and magnetometers to sense orientation, and rotate the spacecraft using magnetorquers and reaction
    wheels. Some CubeSats also now use miniature thrusters for attitude
    control, desaturation, and orbit maintenance.
    + Deployable components, such as antennas and solar panels, are usually
    stored under tension and released with electromagnets or redundant burn
    + Next, select an On-Board Computer (OBC) for Command & Data Handling
    (C&DH) and the flight software that will run on it, such as the open-source
    cFS and F´ frameworks from NASA.
    + Prior to assembly, perform “flatsat” testing with everyth
    ing wired on a
    bench. This is also when you should verify communications with the
    spacecraft via its radios.
    + Once assembled, put the CubeSat through vibration and thermal vacuum
    testing to ensure that it will survive the stresses of launch and the space environment.
    + Finally, obtain the required certifications for earth observation, radio licenses, and an approved deorbit plan. NASA has a helpful guide for
    first-time CubeSat developers with instructions and templates, and also a state-of-the-art technology report.
    (This overview is incomplete—please do not base your spacecraft des
    ign on
    an email newsletter.)

    Changes to AMSAT-NA TLE Distribution for August 25

    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 Thursday evenings around 2300 UTC, or more frequently if
    new high interest satellites are launched. More information may be found at https://www.amsat.org/keplerian-elements-resources/

    Armadillo NORAD Cat ID 44352 (decayed form orbit on 8/23/2022 per Space-Track).

    Those using TLEs provided by Celestrak should be aware of recent changes to
    the URLs for these files. All Celestrak websites are now at celestrak.org
    -- celestrak.com will no longer work.

    There was a problem with the format of the nasa.all version of the TLEs
    last week. The nasabare.txt file was unaffected by this problem, and the
    issue appears to have been resolved in this week's file.

    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.

    Recently completed: Hospital School Program in partnership with Seacrest Studios at Monroe Carell Jr. Children’s Hospital at Vanderbilt, Nas
    Tenn., direct via N4FR. The ISS callsign was NA1SS, and the crewmember was Kjell Lindgren, KO5MOS. Contact was successful on Wednesday, 2022-08-24 17:42:54 UTC with 27 degrees elevation. Congratulations to the Monroe
    Carell Jr. Children’s Hospital at Vanderbilt students and Kjell!

    Current ARISS operations include voice repeater transmissions with the JVC Kenwood D710GA in the Columbus module and APRS packet operation from an identical radio in the Service Module (Zvezda). Packet operations are on 145.825 MHz.

    Kjell Lindgren, KO5MOS, continues to be making general contacts on the cross-band repeater. He is using NA1SS. 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 latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html
