Voice contacts:
​All stations are capable of supporting contacts with schools and other types of educational organizations around the world. Occasionally, astronauts will do general contacts with hams on the ground using the Columbus voice repeater as their schedule allows.

SSTV:
Periodically throughout the year, we'll schedule SSTV events from the Zvezda ham radio. Details will be listed on the SSTV gallery site and announced via social media.

Next SSTV Event on 70cm at 437.550 MHz:
Starts - May 8 at 10:30 UTC
Ends - May 12 at 16:40 UTC

Note:
The radios and Ham TV are sometimes turned off in support of vehicle, spacewalk, and payload activities going on aboard the space station. Those dates and times will be listed on this site and announced via social media as they are scheduled by NASA planners.
