U.S. 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.

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.

CAMSAT XW-4 (CAS-10) Scheduled for Deployment Today

The CAMSAT XW-4 (CAS-10) satellite was launched into the Chinese Space Station on November 12, 2022 aboard China’s Tianzhou-5 cargo spacecraft, and was launched by the Long March-7 Y6 launch vehicle from the Wenchang Launch Center in Hainan, China. It is currently planned that the XW-4 (CAS-10) satellite will be separated from the Chinese space station and enter operational orbit at 01:30 UTC on December 18, 2022.

The functions of XW-4 (CAS-10) satellite include UHF CW telemetry beacon, GMSK telemetry data transmission, V/U mode linear transponder, a visible light band space camera.

After the satellite completes the in-orbit test and works normally, the space camera photo download will be open to amateur radio enthusiasts all over the world. When the relevant remote control command is received by the satellite, the GMSK telemetry channel will be used to downlink the photo storage information and photo data, and the telemetry data will stop sending at that time.

XW-4(CAS-10) satellite adopts a 8U CubeSat structure with a mass of about 12kg, an on-orbit envelope size of 1007x790x475mm with four solar array panels and a three-axis stabilized attitude control system is used, long-term power consumption is about 18.3 Watts.

XW-4 Technical specifications are as follows:

  • CW telemetry beacon:
    • Frequency: 435.575MHz
    • RF power: 20dBm
    • CW rate: 22wpm
  • GMSK telemetry:
    • Frequency: 435.725MHz
    • RF power: 23dBm
    • Data rate: 4800bps
  • V/U mode linear transponder:
    • Uplink frequency: 145.870MHz
    • Downlink frequency: 435.180MHz
    • RF power: 20dBm
    • Bandwidth: 30kHz
    • Spectrum inverted
  • Photo download remote control:
    • Coming soon…

Preliminary Keplerian elements, as supplied by CAMSAT are as follows:

CAS-5A Designated Fengtai-OSCAR 118 (FO-118)

On December 9, 2022, the CAS-5A satellite was launched on a Smart Dragon-3 Y1 launch vehicle from the Chinese sea launch platform in the Yellow Sea. The Chinese Amateur Satellite Group (CAMSAT), working closely with local education authorities, designed, built, tested, and manages the CAS-5A satellite. Thirty-one students from ten high schools learned satellite design, manufacturing, and applications through educational courses initiated by CAMSAT and the Fengtai educational institution. The satellite carries V/u and H/u linear transponders, a V/u FM repeater, and CW and GMSK telemetry beacons for amateur radio use.

At the request of CAMSAT and the CAS-5A team, AMSAT hereby designates the satellite as Fengtai-OSCAR 118 (FO-118). We congratulate all the involved teams, thank them for their contribution to the amateur satellite community, and wish them continued success on this and future projects.

Administration Drafting Executive Order To Simplify Space Rules

WASHINGTON, Dec 9 (Reuters) – U.S. President Joe Biden’s administration is drafting an executive order intended to streamline approval for private rocket launches amid a broader effort to bring legal and regulatory clarity for American companies on everything from space travel to private space stations, according to two U.S. officials familiar with the effort.

The order would be part of a push by the White House’s National Space Council to modernize U.S. space regulation, which has failed to keep up with the increasingly ambitious pace of private-sector investment and development.

The order, slated to be ready for Biden to sign by early 2023, is meant to simplify licensing procedures under existing laws for more routine space activities like launching rockets and deploying satellites

Then, at the request of CAMSAT and the CAS-5A team, AMSAT has designated the satellite as Fengtai-OSCAR 118 (FO-118) on December 15, 2022. See Drew Glasbrenner, KO4MA and OSCAR Number Administrator’s bulletin (above)) for details.

Originally FO-118 was thought to be NORAD Cat ID 54682, but more recent TLE have revealed that CAS 5A is actually object 54684 (2022-167C). Thanks to Nico Janssen, PA0DLO, for the update on the correct NORAD Cat ID for FO-118 (formally CAS-5A).

Therefore, the following satellite has been added to this week’s AMSAT-NA TLE distribution:

Spacewalk From ISS With Two Cosmonauts Cancelled

The Roscosmos Mission Control team in Moscow postponed Wednesday evening’s planned spacewalk with two cosmonauts to evaluate the situation and data from the Soyuz spacecraft. None of the crew members aboard the International Space Station were in danger, and all conducted normal operations throughout the day.

Roscosmos is closely monitoring Soyuz spacecraft temperatures, which remain within acceptable limits. NASA and Roscosmos continue to coordinate external imagery and inspection plans to aid in evaluating the external leak location. Plans for an additional inspection of the Soyuz exterior using the station’s Canadarm2 robotic arm are underway.

The leak was first detected around 7:45 p.m. EST Dec. 14 (0045z on Dec. 15) when data from multiple pressure sensors in the cooling loop showed low readings. At that time, cosmonauts Sergey Prokopyev and Dmitri Petelin were preparing to conduct a spacewalk. The cosmonauts did not exit the space station, and no crew members were exposed to the leaking coolant.

The Soyuz MS-22 spacecraft carried NASA astronaut Frank Rubio and Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin into space after launching from the Baikonur Cosmodrome in Kazakhstan on Sept. 21.

[NOTE: All amateur radio equipment aboard the ISS is switched off during docking maneuvers and EVAs (spacewalks)]

Hamfests, Conventions, Maker Faires, and Other Events

AMSAT Ambassadors provide presentations, demonstrate communicating through amateur satellites, and host information tables at club meetings, hamfests, conventions, maker faires, and other events.

AMSAT Ambassador Clint Bradford K6LCS has a few satellite presentations scheduled …
-Greenville, North Carolina (1/10/23)
-Ontario, Canada (1/16/23)
-Thames Valley, England (5/11/23)

Think a 90-minute lively, informative, and fun “How to Work the Easy Satellites” Zoom presentation would be appropriate for your convention or club? Always included are overviews of the ARRL, AMSAT, and ARISS. And pre-presentation questions are welcome. Visit http://www.work-sat.com for more information.

CAMSAT XW-4 (CAS-10) Satellite To Be Deployed December 18th

The CAMSAT XW-4 (CAS-10) satellite was launched into the Chinese Space Station on November 12, 2022 aboard China’s Tianzhou-5 cargo spacecraft, and was launched by the Long March-7 Y6 launch vehicle from the Wenchang Launch Center in Hainan, China. It is currently planned that the XW-4 (CAS-10) satellite will be separated from the Chinese space station and enter operational orbit at 01:30 UTC on December 18, 2022.

Initial post-deployment TLEs :

CAS-5A Designated Fengtai-OSCAR 118 (FO-118)

On December 9, 2022, the CAS-5A satellite was launched on a Smart Dragon-3 Y1 launch vehicle from the Chinese sea launch platform in the Yellow Sea. The Chinese Amateur Satellite Group (CAMSAT), working closely with local education authorities, designed, built, tested, and manages the CAS-5A satellite. Thirty-one students from ten high schools learned satellite design, manufacturing, and applications through educational courses initiated by CAMSAT and the Fengtai educational institution. The satellite carries V/u and H/u linear transponders, a V/u FM repeater, and CW and GMSK telemetry beacons for amateur radio use.

At the request of CAMSAT and the CAS-5A team, AMSAT hereby designates the satellite as Fengtai-OSCAR 118 (FO-118). We congratulate all the involved teams, thank them for their contribution to the amateur satellite community, and wish them continued success on this and future projects.
