Here is the schedule for power down and power up. Service module radio power down Thu 2025-11-27 10:35 to 10:40 UTC Columbus module radio power down Thu 2025-11-27 10:40 to 10:45 UTC Service module radio power up Fri 2025-11-28 10:15 to 10:20 UTC Columbus module radio power up Fri 2025-11-28 10:20 to 10:25 UTC ####################################################################################################################################### If you happen to be hearing a scheduled school ARISS contact, please DO NOT attempt to call the ISS. First off, the crew is only listening for one callsign that is being used for the school and have been told to ignore any other callsign. Second, the ISS is transmitting to earth on a public domain downlink frequency; but the uplink frequency from the school to the ISS is not published. Again, the crew will be listening only on the frequency that has been given to them to use. Also, if you try to call up on the public domain downlink frequency and happen to be near the school, then you probably just interfered with the school having a successful contact and disappointing a bunch of kids. The bottom line is please be courteous and let the kids have their fun day. They have been planning, working hard, and waiting for a very long time and we really don’t want to see them disappointed. Please use the crossband repeater when it is available. You just never know who might pop on. ####################################################################################################################################### Many times, a school may make a last minute decision to do a Livestream or run into a last minute glitch requiring a change of the URL but we at ARISS may not get the URL in time for publication. You can always check https://live.ariss.org/ to see if a school is Livestreaming. ARISS YouTube Channel: ARISS - Amateur Radio on the ISS - YouTube. Here you will also find past contact videos. The crossband repeater continues to be active. 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. ####################################################################################################################################### 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 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour 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 sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to 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 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.

For any given expedition, we typically may not schedule: 1. Anything the first 3 weeks. 2. During EVA weeks 3. At least 2 weeks prior to the Increment change. 4. No contacts during meal and exercise periods. 5. No contacts during post-sleep and pre sleep (before Ø8:ØØ UTC and after 19:3Ø UTC) 6. Contacts on the day of Progress docking or undocking are circumspect. Mike Fincke KE5AIT and Gennady Padalka RN3DT produced a video during their stay on Expedition 9.
