You can always check https://live.ariss.org/ to see if a school isLivestreaming. The crossband repeater continues to be active. If any crewmember is so inclined, all theyhave to do is pick up the microphone, raise the volume up, and talk on thecrossband repeater. So give a listen,you just never know. Note, all times are approximate. It is recommended that you do your own orbitalprediction or start listening about 10 minutes before the listed time. All dates and times listed follow International StandardISO 8601 date and time format YYYY-MM-DD HH:MM:SS The complete schedule page hasbeen updated as of 2025-04-02 20:00 UTC. (***) Here you will find a listing ofall scheduled school contacts, and questions, other ISS related websites,IRLP and Echolink websites, and instructions for any contact that may bestreamed live. https://www.amsat.org/amsat/ariss/news/arissnews.rtf https://www.amsat.org/amsat/ariss/news/arissnews.txt The successful school list hasbeen updated as of 2025-04-02 20:00 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 Isuspect on other social media sites with people asking why they are not hearingthe crew make general contacts. Firstoff the crew is very busy on the ISS and they simply may not have the time tojust pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that weat ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better scheduleyour 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 07:30 – 19:30 UTC. Themost common times to find a crew member making casual periods are about onehour after waking up and about an hour before sleeping, when they have personaltime. 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 forgetthat the packet system is sometimes active. Check the status at https://www.ariss.org/or http://www.issfanclub.euto see if the packet system is active or not. 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 operationmode can be found at https://www.ariss.org/current-status-of-iss-stations.html Thelatest 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 studentwill be on the telebridge from their own home. **************************************************************************************************************************************** ARISS is very aware of the impact that COVID-19 is havingon schools and the public in general.

AboutARISS: AmateurRadio on the International Space Station (ARISS) is a cooperative venture ofinternational amateur radio societies and the space agencies that support theInternational Space Station (ISS). In the United States, sponsors are theRadio 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 scheduledcontacts via amateur radio between crew members aboard the ISS and students inclassrooms or public forms. Before and during these radio contacts, students,educators, parents, and communities learn about space, space technologies, andamateur radio.

Sending a message bottle in the ocean - Fram2
by Jean Marc Momple 02 Apr '25

02 Apr '25

GE, It may reach a friendly shore… Both Patrice (3B8FA) and myself monitoring Fram2 24/7, not heard so far. We guess that they are not Txing over 3B8. In case anyone has the capability to send a message to Fram2 to ask just one transmission over 3B8 it would be really appreciated. It would be great to Rx Dragon Fram2 at least one time. 73 Jean Marc (3B8DU)

Latest announcement from the Fram2Ham project.
by Joseph Fitzgerald (KM1P) 02 Apr '25

02 Apr '25

Forwarded from the Fram2Ham Discord Server: @ARISS_Chair 15:15 UTC I hope you are having fun and learning a lot! Here are some general announcements: Thank you all for sharing your photos of your station setups! Prior to posting, please carefully check to make sure no SSTV images or partial images are showing up in your station photos. We want to keep the Fram2Ham activity competitive amongst the teams. We appreciate signal reports from you during the SSTV passes. When inputting your images on the Gallery, there is a place to include your signal report. Please make sure your report includes your location, time/orbit of your reception, your signal strength, as well as whether you saw a change in signal during the pass (please describe: example: signal was S9 and then dropped to S3 after time of closest approach (high point in your pass)) This will be very important to understand the reception characteristics during our Fram2Ham experiment. Next SSTV operations are expected to occur during today’s evening passes (April 2) over the USA and Canada. There are some passes in Europe midday on April 3, but some of these opportunities may be subject to change, based on crew research activities, radio availability or radio battery life. We will do our best to keep you informed. Also remember that SSTV operations on Fram2 will only occur during crew wake periods, which is different than 24/7 experienced on ISS. Having the radio turned on and transmitting in a small volume during crew sleep periods does not promote sleeping…and it impacts the results of the crew's sleep studies! The Fram2Ham team is not sure of the crew’s exact sleep schedule. And, during this short duration mission, that sleep schedule might change as they get closer in time to return to Earth. Great work team! Ad Astra!! To the Stars!! Joe Fitzgerald (KM1P) AMSAT Orbital Elements Manager
