    US Schools Selected for ISS Contacts in 2023

    Amateur Radio on the International Space Station (ARISS) has announced a list of seven schools/host organizations selected to host scheduled Amateur Radio contacts with the astronaut crew on the International Space Station (ISS)
    from July to December 2023.

    Earlier this year, nine schools and organizations were selected for contacts that will take place from January to June 2023 with the ISS.

    The primary goal of the ARISS program is to engage young people in science, technology, engineering, arts, and math (STEAM) activities that raise their awareness of space communications, radio communications, space exploration,
    and related areas of study and career possibilities. ARISS does this by organizing scheduled contacts via amateur radio between crew members aboard
    the ISS and students. Before and during these radio contacts, students, educators, parents, and communities take part in hands-on learning activities tied to space, space technologies, and Amateur Radio.

    ARISS anticipates that NASA will be able to provide scheduling opportunities for these host organizations in the U.S. between July - December 2023:

    - A.L. Burruss Elementary School, Marietta, GA
    - Augusta Preparatory Day School, Augusta, GA
    - Bowman Middle School, Bakersville, NC
    - Camp William B. Snyder, Haymarket, VA
    - Covenant Christian Academy, West Peabody, MA
    - Orangeburg Christian Academy, Orangeburg, SC
    - Webb Bridge Middle School, Alpharetta, GA

    The 16 schools and organizations selected for 2023 are now working to
    complete an acceptable plan that demonstrates their ability to execute a ham radio contact with the ISS. Once their equipment plan is approved by the
    ARISS Technical Mentors, the final selected schools/organizations will be scheduled as their availability and flexibility match up with the scheduling opportunities offered by NASA.

    SSTV Unit on ISS is Inoperable

    The ARISS SSTV capability is currently not operational. The SSTV card that interfaces with the ISS computer was damaged and cannot be reliably used.
    Also, ISS has recently switched to a new complement of laptops, which
    requires the ARISS Russia team to develop a new computer interface to support SSTV. ARISS Russia has been actively working this new development and is consulting with the ARISS International hardware/software team on these efforts. Sergey Samburov, RV3DR, ARISS Russia leader, has stated that they expect to complete the SSTV development effort early next year and launch the hardware on a future Progress flight later in the year. Until then, SSTV operations will be down.

    The ARISS International team will keep all informed about SSTV status through its web site http://www.ariss.org and its social media outlets.

    Bill to Eliminate Private Land Use Restrictions on Amateur Radio Introduced

    Congressman Bill Johnson (OH-6) introduced a bill in the U.S. House of Representatives (H.R.9670) on Thursday, December 22, 2022, to eliminate
    private land use restrictions that prohibit, restrict, or impair the ability
    of an Amateur Radio Operator from operating and installing amateur station antennas on property subject to the control of the Amateur Radio Operator.

    The exponential growth of communities subject to private land use
    restrictions that prohibit both the operation of Amateur Radio and the installation of amateur station antennas has significantly restricted the growth of the Amateur Radio Service. These restrictions are pervasive in private common interest residential communities such as single-family subdivisions, condominiums, cooperatives, gated communities, master-planned communities, planned unit developments, and communities governed by community associations. The restrictions have particularly impacted the ability of Amateur Radio to fulfill its statutorily mandated duty of serving as a voluntary noncommercial emergency communications service.

    Congress in 1996 directed the Federal Communications Commission (FCC) to promulgate regulations (Public Law 104-104, title II, section 207, 110 Stat. 114; 47 U.S.C. 303 note) that have preempted all private land use
    restrictions applicable to exterior communications facilities that impair the ability of citizens to receive television broadcast signals, direct broadcast satellite services, or multichannel multipoint distribution services, or to transmit and receive wireless internet services. ARRL attempts to obtain similar relief for Amateur Radio were rejected by the FCC with a statement
    such relief would have to come from Congress.

    ARRL Legislative Advocacy Committee Chairman John Robert Stratton, N5AUS,
    noted that Congress, in 1994 by Joint Resolution, S.J.Res.90/H.J.Res.199, declared that regulations at all levels of government should facilitate and encourage the effective operation of Amateur Radio from residences as a
    public benefit. He continued by stating that "H.R.9670, the Amateur Radio Emergency Preparedness Act, is intended to fulfill that mandate and preserve the ability of Amateur Radio Operators to continue to serve as a key
    component of American critical communications infrastructure."

    768 teams enter The Astro Pi Mission Space Lab 2022/23

    This year, 768 teams made up of 3086 young people from 23 countries sent Raspberry Pi their ideas for experiments to run on board the International Space Station (ISS) for Astro Pi Mission Space Lab.

    Mission Space Lab is part of the European Astro Pi Challenge, an ESA
    Education programme run in collaboration with us at the Raspberry Pi Foundation. Mission Space Lab teams can choose between ‘Life on Earth’
    and ‘Life in space’ for their experiment idea.

    A panel of 25 judges from the Raspberry Pi Foundation and ESA Education assessed the submitted ideas. They were restricted in how many teams could be accommodated, as time to run experiments on board the ISS is limited, especially for ‘Life on Earth’ experiments which need time in a nadir window. The standard of the submitted ideas was higher than ever, making this the toughest judging yet. The judges were delighted are delighted to announce that 486 teams will move on to Phase 2 of Mission Space Lab: writing the code for their experiments.

    All the teams whose experiment ideas were selected will receive a special
    Astro Pi hardware kit, customised to their idea, to help them write and test the Python programs to execute their experiments. Once the teams of young people have received their kits, they can familiarise themselves with the
    Astro Pi hardware and then create and test (and re-test!) their programs.

    Changes to AMSAT-NA TLE Distribution for December 23, 2022

    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/

    The following satellite has been added to this week's AMSAT TLE Distribution:

    CAS-10 NORAD Cat ID 54816

    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.

    No school contracts are currently reported.

    Satellite Shorts From All Over

    + NASA has a long history of hiding secret messages in its spacecraft and
    that tradition continued with the launch of the Orion crew capsule in
    November on top of the Artemis I rocket. Five hidden messages were placed in the Orion capsule ranging from Morse Code to musical notes. In the middle of the capsule, above the cockpit control console, was a Morse Code message that spelled out the name "Charlie" in remembrance of former Orion Deputy Program Manager Charlie Lundquist, who died in 2020. [ANS thanks ARRL for the above information.]

    + In still more legislative news, Congresswoman Debbie Lesko (AZ-08)
    introduced a bill in the U.S. House of Representatives (H.R. 9664) on
    December 21, 2022, to require that the Federal Communications Commission
    (FCC) replace the current HF digital symbol rate limit with a 2.8 kHz
    bandwidth limit. [ANS thanks ARRL Letter for the above information.]

    + Possibly due to a micrometeoroid or debris strike, the Soyuz MS-22 capsule docked to the ISS has suffered an external radiator coolant leak. If it is determined to be unsafe for a crewed return trip, cosmonauts Sergey Prokopyev and Dimitri Petelin along with NASA astronaut Frank Rubio would be
    effectively trapped until a replacement could be launched. That replacement, the Soyuz MS-23 capsule, is apparently being accelerated for a potential uncrewed launch and would be remotely piloted to the ISS. This is possibly
    the most significant "emergency" situation in the 20+ year history of the
    ISS. [ANS thanks The Orbital Index for the above information.]

    + Another roll-out solar array was installed and deployed by astronauts Frank Rubio and Josh Cassada outside the International Space Station on a spacewalk Thursday, Dec. 22, a day later than previously planned after the space
    station needed to dodge a piece of space junk. The original solar panels launched on four space shuttle missions from 2000 to 2009. As expected, the efficiency of the station's original solar arrays has degraded over time.
    NASA is upgrading the space station's power system with the new roll-out
    solar arrays - at a cost of $103 million - which will partially cover six of the station's eight original solar panels. [ANS thanks SpaceflightNow for the above information.]
