Through these ARISS ham radioconnections, students ask the ISS crew questionsabout life in space, career opportunities or other space-related topics.Students spend about four to six months in formal and informal educationsettings preparing for their contact. Preparation for the experience motivatesyouth to learn about radio waves, space technology, ISS research, science, geographyand the space environment. In many cases, the students help write pressreleases, convey ARISS activities through social media and give presentationson the contact to their fellow students and to the local community. They alsocan fully engage in the ARISS contact by helping set up an amateur radio groundstation at the school and then using that station to talk directly with theonboard crew member.

(***) 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.

URESAT-1 launch today from Vanderberg (SpaceX TR-8)
by Félix Páez 12 Jun '23

12 Jun '23

Dear friends, Today it is planned the launch of our satellite URESAT-1 (HADES-B ITU designation). The satellite has been a joint effort by AMSAT-EA, URE (the equivalent in Spain for ARRL), private companies and Universities. It flies on the SpaceX Transporter-8 mission to be launched today at 21.19 UTC from Vandenberg AFB. URESAT-1 will not be deployed directly from the Falcon-9 as it is contained in the D-Orbit ION Orbital Transfer Vehicle (OTV). The Falcon-9 will deploy the OTV 1h and 20 minutes after launch and this OTV will be orbiting the Earth for several days before deploying URESAT-1 along with other satellites (initially for 1 week). We will try to provide TLEs for it as soon as we have them. The satellite's main mission is to act as an FM voice and FSK data repeater (like AX.25). It has a SSTV cam that alternates between a live image (without pointing) and stored images. It also has a chess game so players on Earth can play against it. Periodically the satellite transmits the state of the game, including the chess board, as well as the last movement made and who's turn (players or satellite). Work frequencies are as follows: Uplink: 145.975 MHz/145.925 MHz (aux), Modes: FM voice without subtone, FSK 50 bps, AFSK, AX.25, APRS 1200 / 2400 bps Downlink: 436.888 MHz, Modes: FM voice, CW, FSK 50 bps telemetry, SSTV Robot 36, voice beacon with callsign AO4URE. Be aware that the FM transponder needs to be activated first time by telecommand. Here you have the document describing the transmissions: https://www.amsat-ea.org/app/download/13366685/AMSAT+EA+-+URESAT-1+Transmis… Here you have an sample file with the audio of a telemetry file (chess board): https://www.amsat-ea.org/app/download/13398144/URESAT-1_sample_FSK_telemetr… Here it is the Linux x86 / ARM decoder for telemetry: https://www.amsat-ea.org/app/download/13395017/URESAT-1_telemetry_decoder_L… If the satellite works fine we will deliver a program for Linux so players can send the chess moves to the satellite! Fingers crossed! 73, Felix EA4GQS - AMSAT EA President
