ARISS-USA Now a Non-profit Organization
ARISS-USA, a Maryland not-for-profit corporation, is now recognized by the United States Internal Revenue Service as a Section 501(c)(3) charitable, scientific, and educational organization. ARISS-USA is the US segment of the ARISS (Amateur Radio on the International Space Station) international working group. With this IRS determination, donations to ARISS-USA become tax-deductible in the US, retroactive to the ARISS-USA incorporation on May 21, 2020. This change in status allows ARISS-USA to solicit donations and grants.
As a new entity, ARISS-USA will continue to promote student involvement with the astronauts on the International Space Station via amateur radio. Working with educational organizations, ARISS provides exciting opportunities to inspire, engage and educate our next generation of space explorers through STEAM (science, technology, engineering, arts and math) activities and content. ARISS-USA Executive Director, Frank Bauer, commented, “The educational scope and reach of what ARISS accomplishes has grown significantly since our beginnings in 1996. We are actively working to extend student’s reach even further. This, through the pursuit of potential student opportunities on human spaceflight missions beyond low Earth orbit, as part of our Amateur Radio Exploration (AREx) Program. First AREx destination: the Moon!”
ARISS-USA continues its collaborative work with ARISS International and US sponsors, partners, and interest groups. The ARISS-USA TEAM remains deeply indebted to its partners ARRL and AMSAT, who enabled the birth of ARISS, and to its steadfast sponsors, NASA Space Communication and Navigation (SCaN) and the ISS National Lab (INL).

Contests On QO-100 Allowed In Time For Yuri Gagarin Contest
AMSAT-DL announced, on April 4, the opening of the QO-100 NB satellite transponder to general contest operation in the upper mixed-mode range.
QO-100 is a Qatari satellite, launched aboard a SpaceX Falcon 9 rocket on November 15, 2018. It operates at 26° East longitude along a geostationary orbit, which means that the satellite's footprint covers Europe, Africa, and Asia, but excludes North America and most of South America.
This weekend (April 10-11) will see the Yuri Gagarin contest. The contest area on the QO-100 geostationary satellite NB transponder for both CW and SSB is:
Uplink area 2400.370 – 2400.490 MHz Downlink area 10489.870 – 10489.990 MHz
Of course, the usual QO-100 NB transponder guidelines also apply here. Therefore, the bandwidth should still be limited to 2.7 kHz and the transmitting power should be reduced to the necessary level, i.e. only as much power as necessary should be used.
Read the AMSAT-DL announcement at https://amsat-dl.org/en/contests-on-qo-100-allowed/
The Yuri Gagarin International DX Contest 2021 is dedicated to the memory of Yuri Gagarin, who realized the first human flight to space, on April 12, 1961.
It runs from 2100 GMT on April 10 until 2100 GMT on April 11, 2021, and the categories include: • SAT Single operator – Satellite QSOs • SAT-GS Single operator – Geostationary Satellite QSOs
Contest rules are at http://gc.qst.ru/en/section/32

Fun While It Lasted, Falcon 9 Telemetry Now Encrypted
A few weeks back Hackaday reported that Reddit users [derekcz] and [Xerbot] had managed to receive the 2232.5 MHz telemetry downlink from a Falcon 9 upper stage and pull out some interesting plain-text strings. With further software fiddling, the vehicle’s video streams were decoded, resulting in some absolutely breathtaking shots of the rocket and its payload from low Earth orbit.
Unfortunately, it looks like those heady days are now over, as [derekcz] reports the downlink from the latest Falcon 9 mission was nothing but unintelligible noise. Since the hardware and software haven’t changed on his side, the only logical conclusion is that SpaceX wasn’t too happy about radio amateurs listening in on their rocket and decided to employ some form of encryption.

NASA Invites Public to Take Flight With Ingenuity Mars Helicopter
NASA is targeting no earlier than Sunday, April 11, for Ingenuity Mars Helicopter's first attempt at powered, controlled flight on another planet. To mark a month of Ingenuity flights, the agency will host several events to bring people along for the ride.
A livestream confirming Ingenuity's first flight is targeted to begin around 3:30 a.m. EDT (07:30z) Monday, April 12, on NASA Television, the NASA app, and the agency's website, and will livestream on multiple agency social media platforms, including the JPL YouTube, and Facebook channels.
Ingenuity arrived at Mars' Jezero Crater Feb. 18, attached to the belly of NASA's Perseverance rover. The helicopter is a technology demonstration with a planned test flight duration of up to 31 days (30 Mars days, or sols). The rover will provide support during flight operations, taking images, collecting environmental data, and hosting the base station that enables the helicopter to communicate with mission controllers on Earth.
The flight date may shift as engineers work on the deployments, preflight checks, and vehicle positioning of both Perseverance and Ingenuity. Timing for events will be updated as needed, and the latest schedule will be available on the helicopter's Watch Online webpage: https://mars.nasa.gov/technology/helicopter/#Watch-Online

Busy month of crew rotations on tap at International Space Station
Seven astronauts and cosmonauts are gearing up for launches April 9 and April 22 to the International Space Station, replacing seven outgoing crew members set to land in Kazakhstan and off the coast of Florida on April 17 and April 28.
The back-to-back crew rotations will make for a busy month on the orbiting research complex, and multiple instances when ARISS operation will be suspended during crew operations. Preparations for the arrival of the fresh crew members are already underway on the space station.
The first step was relocation of a SpaceX Crew Dragon spaceship to a new docking port on the space station April 5. NASA astronaut Mike Hopkins, KF5LJG, commander of the Crew Dragon “Resilience” spaceship, was joined by crewmates Victor Glover, KI5BKC, Soichi Noguchi, KD5TVP, and Shannon Walker, KD5DXB, for the fully automated 45-minute relocation maneuver.
The Dragon astronauts, who launched Nov. 15 as part of SpaceX’s “Crew-1” mission, were aboard the Crew Dragon Resilience spacecraft and suited up for re-entry, just in case the capsule had trouble linking up with the new docking port and needed to return to Earth.
Next was the launch of a Russian Soyuz MS-18 spacecraft with commander Oleg Novitskiy, cosmonaut Pyotr Dubrov, and NASA astronaut Mark Vande Hei, KG5GNP. The Soyuz crew launched from the Baikonur Cosmodrome in Kazakhstan on Friday, April 9 at 3:42 a.m. EDT (0742 GMT).
The crew on the space station will temporarily swell to 10 people until the outgoing Soyuz MS-17 crew departs the research lab one week later.
Undocking of the Soyuz MS-17 spacecraft with commander Sergey Ryzhikov, flight engineer Sergey Kud-Sverchkov, and NASA astronaut Kate Rubins, KG5FYJ, is scheduled for 9:33 p.m. EDT on April 16 (0133z on April 17). The Soyuz capsule is scheduled to parachute to a landing on the steppes of Kazakhstan at 12:56 a.m. EDT (0456 GMT) on April 17. Ryzhikov, Kud-Sverchkov, and Rubins launched Oct. 14 from Baikonur. Their return to Earth on April 17 will wrap up a 185-day mission.
With the Soyuz crew rotation complete, SpaceX and NASA will be cleared to launch the second operational Crew Dragon mission to the space station on April 22.
NASA astronaut Shane Kimbrough, KE5HOD, pilot Megan McArthur, Japanese astronaut Akihiko Hoshide, KE5DNI, and French-born European Space Agency astronaut Thomas Pesquet, KG5FYG, will fly on the Crew-2 mission.
Assuming the Crew-2 mission takes off April 22, Kimbrough and his crewmates will reach the space station for an automated docking at 5:29 a.m. EDT (0929 GMT) on April 23.
Their arrival will start a five-day handover with the Crew-1 astronauts, when the space station will briefly host 11 crew members.
The Crew-1 astronauts are scheduled to board their Crew Dragon Resilience spacecraft and undock from the space station April 28 at 5 a.m. EDT (0900 GMT). The Crew Dragon capsule will fire its Draco thrusters to target a parachute-assisted splashdown off the coast of Florida at 12:35 p.m. EDT (1635 GMT) the same day.

Satellite Shorts From All Over
+ LightCube, an educational mission by Arizona State University, Tempe, to allow a CubeSat in low-Earth orbit (LEO) to be easily operable by members of the general public, has been approved by NASA as one of the 12th CubeSat Launch Initiative (CSLI) projects for 2022-2025. The LightCube CubeSat will provide a platform that increases the number of individuals who can participate in space activities. Specifically, anyone with appropriate amateur radio licensing within their jurisdiction and commercial radio equipment available for purchase for less than fifty dollars will be able to telecommand LightCube. The LightCube CubeSat will respond with a flash visible to the naked eye of the commander. In the process of operating LightCube, the user will inevitably learn important science, technology, engineering, and math (STEM) concepts in areas such as telecommunications, spacecraft design, atmospheric and climate science, and orbital mechanics. (ANS thanks NASA, JoAnne Maenpaa, K9JKM, Harry Bloomberg, W3YJ, and Rick Lindquist, WW1ME, for the above information.)
+ Jean Marc Momple, 3B8DU and an AMSAT Ambassador published an article in the Institution of Engineers Mauritius (IEM) Journal, March 2021, to promoted HAM radio satellite operation worldwide, as the paper was circulated in all affiliated Engineers association globally but the focus was on the regional operation. The link to obtain the document is https://bit.ly/3uHFFCv or go to https://www.iemauritius.com and register to download the March 21 edition of the Journal. (ANS thanks Jean Marc Momple, 3B8DU, for the above information.)
+ GOES-T, NOAA’s latest generation geosynchronous satellite, recently completed vibration, vacuum, and acoustic testing ahead of its December launch. GOES-T packs upgraded traditional weather observation instruments (see https://www.youtube.com/watch?v=8WQAwQ0SGkc for a video intro), including the 16 channel ABI imager (up from 5 channels on the previous generation) with 0.5km - 2km resolution (4x the previous gen). This generation also includes a Geostationary Lightning Mapper, the first lightning mapping system flown in geostationary orbit, which should increase lead time for severe storm warnings and decrease false positives. See https://www.goes-r.gov/spacesegment/glm.html for an overview of the system. (ANS thanks the Orbital Index for the above information.)
+ SpaceX launched 60 more of the company's Starlink Internet communications satellites into orbit from Florida on Wednesday, April 7. A Falcon 9 rocket carrying the spacecraft lifted off as planned at 12:34 p.m. EDT (16:34z). SpaceX recovered the first-stage booster for the rocket by landing it on a barge in the Atlantic Ocean. The satellites deployed to their intended orbit a little more than an hour after launch. (ANS thanks Space Daily for the above information.)
+ A rather fascinating disassembly and analysis of the digital clock from a Soyuz spacecraft can be found at http://www.righto.com/2020/01/inside-digital-clock-from-soyuz.html The mid-1980s vintage clock was judged to be 8 to 10 years behind U.S. space technology of the time, with more that 100 integrated circuits on ten circuit boards. (ANS thanks the Orbital Index for the above information.)
+ Open Research Institute has posted several new YouTube videos updating their work. See https://www.openresearch.institute/ for links. (ANS thanks AMSAT Board Member Michelle Thompson, W5NYV, for the above information.)
+ AO-91 remains operational in COR or "repeater mode." Reminder: Please use only in sunlight and do not use while in eclipse (which "generally" means, if it's dark at your local QTH do not use!). Remember that the current status of most operational satellites can be found at https://www.amsat.org/status/ (ANS thanks AMSAT Board and Fox Command Team Member Mark Hammond, N8MH, for the above information.)

73 and Remember to help keep amateur radio in space, This week's ANS Editor, Mark Johns, K0JM k0jm at amsat dot org
Mark,
Thanks
Interesting that I got a few direct mails already, mainly about the school program and request for sharing information and results obtained when the program completed (as a case study) so that it may be replicated in other countries if successful. That's great if the 3B8 experience may eventually motivate youngsters in other countries in HAM radio and science and technology. It will take a few more months but I will share when the exercise completed.
I just hope that it may motivate some to our hobby.

Since the hardware and software haven’t changed on his side, the only logical conclusion is that SpaceX wasn’t too happy about radio amateurs listening in on their rocket and decided to employ some form of encryption.

NASA Invites Public to Take Flight With Ingenuity Mars Helicopter
NASA is targeting no earlier than Sunday, April 11, for Ingenuity Mars Helicopter's first attempt at powered, controlled flight on another planet. To mark a month of Ingenuity flights, the agency will host several events to bring people along for the ride.
A livestream confirming Ingenuity's first flight is targeted to begin around 3:30 a.m. EDT (07:30z) Monday, April 12, on NASA Television, the NASA app, and the agency's website, and will livestream on multiple agency social media platforms, including the JPL YouTube, and Facebook channels.
Ingenuity arrived at Mars' Jezero Crater Feb. 18, attached to the belly of NASA's Perseverance rover. The helicopter is a technology demonstration with a planned test flight duration of up to 31 days (30 Mars days, or sols). The rover will provide support during flight operations, taking images, collecting environmental data, and hosting the base station that enables the helicopter to communicate with mission controllers on Earth.
The flight date may shift as engineers work on the deployments, preflight checks, and vehicle positioning of both Perseverance and Ingenuity. Timing for events will be updated as needed, and the latest schedule will be available on the helicopter's Watch Online webpage: https://mars.nasa.gov/technology/helicopter/#Watch-Online https://mars.nasa.gov/technology/helicopter/#Watch-Online

Busy month of crew rotations on tap at International Space Station
Seven astronauts and cosmonauts are gearing up for launches April 9 and April 22 to the International Space Station, replacing seven outgoing crew members set to land in Kazakhstan and off the coast of Florida on April 17 and April 28.
The back-to-back crew rotations will make for a busy month on the orbiting research complex, and multiple instances when ARISS operation will be suspended during crew operations. Preparations for the arrival of the fresh crew members are already underway on the space station.
The first step was relocation of a SpaceX Crew Dragon spaceship to a new docking port on the space station April 5. NASA astronaut Mike Hopkins, KF5LJG, commander of the Crew Dragon “Resilience” spaceship, was joined by crewmates Victor Glover, KI5BKC, Soichi Noguchi, KD5TVP, and Shannon Walker, KD5DXB, for the fully automated 45-minute relocation maneuver.
The Dragon astronauts, who launched Nov. 15 as part of SpaceX’s “Crew-1” mission, were aboard the Crew Dragon Resilience spacecraft and suited up for re-entry, just in case the capsule had trouble linking up with the new docking port and needed to return to Earth.
Next was the launch of a Russian Soyuz MS-18 spacecraft with commander Oleg Novitskiy, cosmonaut Pyotr Dubrov, and NASA astronaut Mark Vande Hei, KG5GNP. The Soyuz crew launched from the Baikonur Cosmodrome in Kazakhstan on Friday, April 9 at 3:42 a.m. EDT (0742 GMT).
The crew on the space station will temporarily swell to 10 people until the outgoing Soyuz MS-17 crew departs the research lab one week later.
Undocking of the Soyuz MS-17 spacecraft with commander Sergey Ryzhikov, flight engineer Sergey Kud-Sverchkov, and NASA astronaut Kate Rubins, KG5FYJ, is scheduled for 9:33 p.m. EDT on April 16 (0133z on April 17). The Soyuz capsule is scheduled to parachute to a landing on the steppes of Kazakhstan at 12:56 a.m. EDT (0456 GMT) on April 17. Ryzhikov, Kud-Sverchkov, and Rubins launched Oct. 14 from Baikonur. Their return to Earth on April 17 will wrap up a 185-day mission.
With the Soyuz crew rotation complete, SpaceX and NASA will be cleared to launch the second operational Crew Dragon mission to the space station on April 22.
NASA astronaut Shane Kimbrough, KE5HOD, pilot Megan McArthur, Japanese astronaut Akihiko Hoshide, KE5DNI, and French-born European Space Agency astronaut Thomas Pesquet, KG5FYG, will fly on the Crew-2 mission.
Assuming the Crew-2 mission takes off April 22, Kimbrough and his crewmates will reach the space station for an automated docking at 5:29 a.m. EDT (0929 GMT) on April 23.
Their arrival will start a five-day handover with the Crew-1 astronauts, when the space station will briefly host 11 crew members.
The Crew-1 astronauts are scheduled to board their Crew Dragon Resilience spacecraft and undock from the space station April 28 at 5 a.m. EDT (0900 GMT). The Crew Dragon capsule will fire its Draco thrusters to target a parachute-assisted splashdown off the coast of Florida at 12:35 p.m. EDT (1635 GMT) the same day.

Satellite Shorts From All Over
LightCube, an educational mission by Arizona State University, Tempe, to allow a CubeSat in low-Earth orbit (LEO) to be easily operable by members of the general public, has been approved by NASA as one of the 12th CubeSat Launch Initiative (CSLI) projects for 2022-2025. The LightCube CubeSat will provide a platform that increases the number of individuals who can participate in space activities. Specifically, anyone with appropriate amateur radio licensing within their jurisdiction and commercial radio equipment available for purchase for less than fifty dollars will be able to telecommand LightCube. The LightCube CubeSat will respond with a flash visible to the naked eye of the commander. In the process of operating LightCube, the user will inevitably learn important science, technology, engineering, and math (STEM) concepts in areas such as telecommunications, spacecraft design, atmospheric and climate science, and orbital mechanics.

GOES-T, NOAA’s latest generation geosynchronous satellite, recently completed vibration, vacuum, and acoustic testing ahead of its December launch. GOES-T packs upgraded traditional weather observation instruments (see https://www.youtube.com/watch?v=8WQAwQ0SGkc https://www.youtube.com/watch?v=8WQAwQ0SGkc for a video intro), including the 16 channel ABI imager (up from 5 channels on the previous generation) with 0.5km - 2km resolution (4x the previous gen). This generation also includes a Geostationary Lightning Mapper, the first lightning mapping system flown in geostationary orbit, which should increase lead time for severe storm warnings and decrease false positives. See https://www.goes-r.gov/spacesegment/glm.html https://www.goes-r.gov/spacesegment/glm.html for an overview of the system. (ANS thanks the Orbital Index for the above information.)
SpaceX launched 60 more of the company's Starlink Internet communications satellites into orbit from Florida on Wednesday, April 7. A Falcon 9 rocket carrying the spacecraft lifted off as planned at 12:34 p.m. EDT (16:34z). SpaceX recovered the first-stage booster for the rocket by landing it on a barge in the Atlantic Ocean. The satellites deployed to their intended orbit a little more than an hour after launch. (ANS thanks Space Daily for the above information.)
