ARISS anticipates that the contact would be held between January 1, 2022 and June 30, 2022. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan. The deadline to submit a proposal is March 31st, 2021. Proposal information and more details such as expectations, proposal guidelines and the proposal form can be found at www.ariss.org. An ARISS Introductory Webinar session will be held on February 25th, 2021 at 8 PM ET. The Eventbrite link to sign up is: https://ariss-proposal-webinar-spring-2021.eventbrite.com The Opportunity Crew members aboard the International Space Station will participate in scheduled Amateur Radio contacts. These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session. An ARISS contact is a voice-only communication opportunity via Amateur Radio between astronauts and cosmonauts aboard the space station and classrooms and communities. ARISS contacts afford education audiences the opportunity to learn firsthand from astronauts what it is like to live and work in space and to learn about space research conducted on the ISS. Students also will have an opportunity to learn about satellite communication, wireless technology, and radio science. Because of the nature of human spaceflight and the complexity of scheduling activities aboard the ISS, organizations must demonstrate flexibility to accommodate changes in dates and times of the radio contact. Amateur Radio organizations around the world with the support of NASA and space agencies in Russia, Canada, Japan and Europe present educational organizations with this opportunity. The ham radio organizations’ volunteer efforts provide the equipment and operational support to enable communication between crew on the ISS and students around the world using Amateur Radio.

RadFxSat-2 has been identified as OBJECT C
by Mark Hammond 02 Feb '21

02 Feb '21

2 February 2021 Testing and characterization of RadFxSat-2/Fox-1E continues.After user reports and additional verification that the linear transponder is at least partially functioning with a low level downlink signal, the Engineering and Operations teams worked to identify which satellite, or Object, orbited from the Virgin Orbit Launch Demo 2 is actually RadFxSat-2/Fox-1E.Several objects have been suspected (D, C, and M), with Object C being suggested recently by Drew Glasbrenner, KO4MA.Recently, these satellites have sufficiently spread apart to allow testing to determine which object is RadFxSat-2/Fox-1E. During the 2 Feb 2021 0240 UTC passes, command station Mark Hammond, N8MH, compared Objects D, C, and M for the “best fit” for received signals with Doppler correction on both the uplink and downlink frequencies for each of the candidate objects.Objects D and M were quickly eliminated from further consideration, due to poor frequency predictions of Doppler correction compared to observed signals. The clear best fit is Object C, which is known OBJECT C, INTELDES 2021-002C, and NORAD CAT ID 47311/./Therefore, AMSAT is happy to identify Object C/2021-002C/47311U as RadFxSat-2/Fox-1E.Thank to Alan Biddle, WA4SCA, for support during the identification. It should be noted that 18 SPS has not yet approved the identification for cataloguing.Final determination of the object assignment comes from the squadron. The Engineering and Operations teams appreciate the community’s cooperation thus far and affirm the request that users do not attempt to use the transponder until further notice.The proper identification will allow further characterization of the satellite’s condition through additional testing. On behalf of the Engineering and Operations Team, -- Mark L. Hammond [N8MH] AMSAT Director and Command Station

:Re: Cubesats
by Ray Soifer 02 Feb '21

02 Feb '21

The Cubesats thread that I started several days ago has morphed into a general dscussion of AMSAT satellites. Mr Moderator, please change the thread accordingly. Before that happened, some excellent technical points were made about Cubesats. What;s the best way to get them into the hands of designers and builders? Speaking personally, I was impressed by how little things have chaged since the early days. As the French say, "plus ca change, plus la meme chose." Proolems with negative power budgets, antenna deployment, thermal design, lack of rad-hard components, and IHU failures, to just a few, were evident in the 1970s and 1980s, and were written about at the time. If anything, they have been made worse by the inadequate financial resources and lack of technical sophistication which are all too common in the Cubesat world. To those who participated, thank you. 73 Ray W2RS

Re: Cubesats
by Daniel Schultz 02 Feb '21

02 Feb '21

Hams are not poor, many of us are willing to spend thousands on the latest radio gear, and DX-peditions have raised substantial amounts of money to finance trips to remote islands so that contributors can get a rare QSL card. We have the financial means but are lacking the organization. We have to convince members that if they can spend $2000 on a new radio then they can also send a $2000 check to AMSAT if they want new satellites in orbit. Some of our members are quite satisfied with low orbit FM satellites and think that keeping these in space is the top priority. Many others still remember the days of AO-10, AO-13 and AO-40 (when it was working). Many of those members became discouraged and left AMSAT when we failed to replace those satellites with new ones. We can keep the LEO sats in orbit for those who want them by offering our radio boards to universities and other groups who want to build CubeSats but don't know a lot about radio. To serve the long term interests of the amateur radio community we must set our sights on larger, more powerful and higher satellites, and we will probably have to pay for those launches because the era of free launches for satellites larger than a Cubesat is gone and not coming back. Fortunately the newly emerging private space industry offers launch options for much less money than the days when we got "free" launches from the government. The short lifetime of Phase 3D is a valid point, it was intended to last much longer except for a simple and avoidable mistake. The trouble is that P3D was a one of a kind mission with no possibility of a follow up mission. Future AMSAT HEO programs must be ongoing programs in which the lessons learned from earlier satellites can feed into subsequent missions. AMSAT must also prove that we are capable of learning lessons from ours and other's failures and applying them to new satellites. AMSAT has to prove that it is capable and worthy of such support, because we are only as good as our last failure. The petty bickering that has occurred recently has to end so that we can present a professional appearance to outsiders. I was working in the Hubble control center when the flawed mirror was discovered. Much has been written about why the conflicting optical tests were not followed up, but the project WAS behind schedule and over budget and Congress was looking at cancellation if it fell any further behind. Schedule and budget pressure are very real worries for NASA missions. I will simply point out that NASA repaired the flawed telescope within three years at minimal cost and the telescope has worked flawlessly for over 30 years now and is still going strong. That is a pretty successful failure. And NASA runs the CubeSat Launch Initiative and deploys many of them from the ISS, so it obviously does support CubeSats.

PSAT-2 SSTV operation change
by Tomáš Urbanec 02 Feb '21

02 Feb '21

We would like to inform you, that PSAT-2/NO-104 transponder and SSTV camera are still going strong. For a long time we were unable to command the sat from Europe due to night passes and COVID restrictions. Now we were able to refresh all the picture memories and we moved the timing of transmissions so that when the sat detects PSK31 signals in uplink, it downlinks the SSTV pictures more frequently and in MP73 format. Feel free to experiment, we reccomend to transmit the PSK signal loop between 400 and 1000Hz in downlink to accomodate between the beacons and SSTV signals. We are still offering interested stations the possibility to command the camera and obtain the pictures of their side of the Earth. Just contact us for info. Good luck in experimenting and have a fun! Tomas OK2PNQ
