    MESAT-1 to Carry AMSAT Linear Transponder Module

    An AMSAT-constructed linear transponder module is included in the MESAT 3U satellite to be deployed as part of NASA's upcoming ELaNa 43 mission.

    MESAT-1 is a stack of three tech-stuffed 4-inch cubes assembled at the University of Maine and destined for space in 2022. The first satellite of
    its kind ever built in Maine, MESAT-1 carries three imaging experiments proposed by Maine schools and a 2-way radio for use by ground control and amateur radio enthusiasts.

    MESAT-1 was originally projected to launch from Vandenberg Space Force
    Base, California, in June 2022, but has been delayed. The satellite will be carried by a Firefly Aerospace "Alpha" rocket and released into a Sun-synchronous orbit about 555 kilometers (350 miles) above Earth. It will
    fly nearly over the poles traveling at about 7.8 kilometers per second
    (17,000 mph), making a full orbit in roughly 100 minutes. Any given
    location on Earth will experience 4 to 6 passes per day, with each pass
    lasting less than 15 minutes. MESAT-1 is expected to remain in space for
    well over a decade.

    A statewide competition in 2019 drew payload proposals from schools across Maine. Three projects were selected for the MESAT-1 mission: ALBEDO,
    IMAGER, and HAB.

    ALBEDO: Saco Middle School will study reflected light (albedo) and local temperature in urban and rural areas, with the idea that urban heat islands could be mitigated through architectural designs that reflect more light.

    IMAGER: Fryeburg Academy will photograph shallow coastal waters as part of
    an effort to distinguish turbidity and phytoplankton concentration from
    space. The academy is collaborating with the Wells National Estuarine
    Research Reserve.

    HAB: Falmouth High School will work on early detection of harmful algal
    blooms by measuring atmospheric temperature and water vapor levels around
    bloom areas. They will watch blooms develop, move, and disperse.

    The main radio aboard MESAT-1 is a linear transponder module (LTM-1) built
    by the nonprofit Radio Amateur Satellite Corporation (AMSAT), a partner in
    the project. The ground station operator will command the satellite through LTM-1 and the module will transmit telemetry back to Earth. LTM-1 will also
    be made available to amateur radio operators for 2-way communication.

    UMaine applied to the International Amateur Radio Union to coordinate its planned frequency use for MESAT-1. The IARU approved this plan on 22
    November 2021:
    Telemetry beacon downlink: 435.800 MHz 1200 baud BPSK
    Transponder uplink: 145.910-145.940 MHz
    Transponder downlink: 435.810-435.840 MHz

    MESAT-1 carries a second radio, an EyeStar transmitter, originally intended
    to interface with the satellite's built-in GPS and the GlobalStar network
    to provide the ground team with accurate, hourly position information. This aspect of the mission was altered during MESAT-1 construction. The EyeStar
    unit will serve only a minimal function on MESAT-1.
    Background on Maine's First CubeSat

    MESAT-1 exists thanks to NASA’s CubeSat Launch Initiative (CSLI) an
    d the
    Maine Space Grant Consortium. Through CSLI, NASA has selected more than 200 CubeSat missions for the Educational Launch of Nanosatellites program. More than 130 ELaNA satellites have been launched at NASA's expense since 2011.

    In 2018, Maine Space Grant kicked off a pilot Maine CubeSat Launch
    Initiative to involve students and teachers from across the state in
    designing CubeSat missions. Through a competitive process, the consortium selected three experiments to propose for NASA's 2019 ELaNa opportunity.

    The MESAT-1 proposal was accepted by NASA early in 2020. The satellite was paired with launch provider Firefly Aerospace for ELaNa mission 43.

    Dr. Ali Abedi, director of the WiSe-Net Lab at UMaine Orono, assigned three UMaine graduate students the task of producing the satellite. With the
    support of the Maine Space Grant Consortium, they completed MESAT-1 in time
    for a 2022 launch.

    FoxTelem Version 1.12 Released

    A new version of FoxTelem has been released ahead of the launch of MESAT-1.
    The new version will be required in order to decode MESAT-1 telemetry.
    MESAT-1 has an AMSAT Linear Transponder Module (LTM) and will transmit
    health data and images at 1200bps using BPSK. FoxTelem will decode and
    display the images from the University of Maine multi-spectral camera, as
    well as other data about the spacecraft.

    This version of FoxTelem will still support all previous spacecraft and the CubeSat Simulator.

    You can download it from these locations:

    In addition to support for MESAT-1 this version also includes several bug
    fixes and enhancements. Questions or comments (other than "when is the
    launch", because I don't know) may be directed to chrisethompson [at]
    gmail.com or to g0kla [at] arrl.net. Issues or bugs can be logged on github

    GreenCube in Digipeater Mode

    The S5Lab research team of the University "La Sapienza," Rome, Italy, the Italian Space Agency and AMSAT Italia are happy to inform the ham radio community that the GreenCube satellite will be switched in digipeater mode between 29-Oct-2022 00:01 UTC and 30-Oct-2022 23:59 UTC. Information on the setup required to access the satellite can be found on the team's web site https://www.s5lab.space/index.php/digipeater/.

    The S5lab team of Sapienza provides the software needed to communicate with
    the satellite along with a technical guide of the setup and the GUI
    features. The archive contains:

    The user manual
    The Graphical User Interface (GUI)
    The Terminal Node Controller (TNC) software
    The GNURadio script to receive and transmit

    The software kit can be downloaded from the same web page. The satellite digipeater implements a store-and-forward message service and works at
    435.310 Mhz (U/L and D/L).

    The 3U cubesat was launched on the Vega-C maiden flight on 13-Jul-2022 in a
    MEO orbit. The GreenCube project is being carried out through a
    collaboration agreement between the Italian Space Agency and Sapienza University of Rome, with the participation of ENEA and University Federico
    II of Naples. As for the radio frequency communications, a strong and
    effective cooperation with AMSAT Italia has been established, whereby AMSAT Italia endorsed the frequency coordination request.

    Changes to AMSAT-NA TLE Distribution

    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/

    No changes to the satellite list this week.

    ISS Partners Weigh Options for Using Commercial Space Stations

    Partner agencies on the International Space Station program say they are in discussions about how they will use, and pay for, commercial space stations that will replace it.

    Representatives of several countries currently involved in the ISS said
    during a panel at the American Institute of Aeronautics and Astronautics

    ASCEND conference in Las Vegas, Nevada on Oct. 25 that they are looking at options for how to continue work they currently do on the ISS on the
    commercial space stations in low Earth orbit (LEO) NASA is helping develop
    to replace it at the end of the decade.

    “With the commercialization of LEO, it is really necessary to revis
    it our
    principles of doing cooperation,” said Peter Gräf, director of
    and science at the German space agency DLR. Germany is the biggest
    contributor to ESA’s share of the ISS and actively uses the station
    fundamental and applied research.

    He said discussions among agencies and companies had started on how those arrangements would change with a commercial station. “We need to fi
    nd ways
    to work together, certainly in other ways than we did before,” he s
    “There are a lot of options available and the main players are in h
    discussions on that.”

    The ISS today relies extensively on barter arrangements among participating agencies, providing services to cover their share of operations of the
    station. Such arrangements are unlikely to work for commercial stations, however.

    “We need to find a new way of cooperating,” said Nicolas Ma
    ubert, space
    counselor at the French Embassy in the U.S. and representative of the
    French space agency CNES in the U.S., citing the challenges of extending current barter arrangements to commercial stations. “We need to put
    on the
    table every option.”

    “The bottom line for all is that there is a strong demand for capab
    in low Earth orbit,” Gräf said. “It’s quite cl
    ear there will be a human
    outpost in LEO, no matter what the future will bring.”
