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 Earthâ€Ö
and ‘Life in spaceâ€Ö 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 Earthâ€Ö 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/

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.]
