Sixteen new amateur satellites in orbit from Space-X Transporter 7 launch
by Joseph B. Fitzgerald 19 Apr '23

19 Apr '23

Our friends at Libre Space show 16 spacecraft using amateur frequencies on the recent Space-X transporter 7 launch, some IARU coordinated, some not. https://community.libre.space/t/spacex-f9-transporter-7-2023-04-15-06-47-ut… Celestrak has published element sets derived from Space-X deployment data. See https://celestrak.org/NORAD/elements/supplemental/sup-gp.php?FILE=transport… Celestrak also made an attempt to match Space-X derived TLEs to USSF tracked objects: https://celestrak.org/NORAD/elements/supplemental/transporter.match.txt but I don't consider that authoritative. Note that RoseyCubesat-1 and INSPIRE-Sat 7 share the same element set which seems strange as I understand that they are two independent spacecraft. Please feel free to share any observations here on AMSAT-BB de KM1P Joe

If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know. Note, all times are approximate. It is recommended that you do your own orbital prediction or start listening about 10 minutes before the listed time. All dates and times listed follow International Standard ISO 8601 date and time format YYYY-MM-DD HH:MM:SS The complete schedule page has been updated as of 2023-04-19 18:00 UTC. (***) Here you will find a listing of all scheduled school contacts, and questions, other ISS related websites, IRLP and Echolink websites, and instructions for any contact that may be streamed live. https://www.amsat.org/amsat/ariss/news/arissnews.rtf https://www.amsat.org/amsat/ariss/news/arissnews.txt The successful school list has been updated as of 2023-04-18 16:30 UTC. https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### Comments on making general contacts I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 0730 - 1930 UTC. The most common times to find a crew member making casual periods are about one hour after waking and before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is active. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html ######################################################################################################################################## A multi-point telebridge contact means that each student will be on the telebridge from their own home. **************************************************************************************************************************************** ARISS is very aware of the impact that COVID-19 is having on schools and the public in general. As such, we may have last minute cancellations or postponements of school contacts. As always, I will try to provide everyone with near-real-time updates.

In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the ISS National Lab and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEAM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or public forms. Before and during these radio contacts, students, educators, parents, and communities learn about space, space technologies, and amateur radio.

What *is* the status of FO-118?
by David Spoelstra 19 Apr '23

19 Apr '23

I was excited when it was first launched. There were YouTube videos of people making contacts. Now I see a lot of people saying they don't hear it on the AMSAT Status page. Every once in a while someone lists that they did hear it. I listen all the time but have never heard it. I did a lot of searching for current information on the bird but didn't find anything. Does anyone know the current status of the bird or have any up-to-date information on it - especially its health? Thanks! -David, N9KT

Re: AO-91 and RS-44 not functioning?

AO-91 seems to be ok on some days and passes, not on others. You should all be aware that it is not at all functional when it is not in the sun. It may take some time after it enters the sun to be available, or there may be something else going on. Nothing looks especially odd (given the dying batteries) in the telemetry, but the telemetry itself arrives on some passes and not on others. 73, Burns WB1FJ On Tue, Apr 18, 2023 at 4:18 PM Clint Bradford via AMSAT-BB < amsat-bb(a)amsat.org> wrote: > Some hams are working AO-91 successfully the past 24 hours … according to > the Live OSCAR Status site: > > https://www.amsat.org/status/ > > Maybe now more than ever (recently) - Make sure that we ALL submit our > pass data there! > > Clint K6LCS > > > > On Apr 18, 2023, at 1:12 PM, Vince Fiscus, KB7ADL via AMSAT-BB < > amsat-bb(a)amsat.org> wrote: > > At 07:39 PM 4/18/2023 +0000, you wrote: > > Dear Folks: > > Today, neither AO-91 nor RS-44 seemed to be functioning. > > > ----------------------------------------------------------- > > Sent via AMSAT-BB(a)amsat.org.

What's sad it there are a number of linear sats not functioning or working well: FO-29, not active, FO-118 not active, CAS-4A not active, and XW-2C has issues cutting out it's downlink. KB7ADL
