Next week, the ARISS team will be transmitting SSTV images continuously from June 21 until June 26. The blog
http://ariss-sstv.blogspot.com/ mentions that the images will be related to some of the amateur radio activities that have occurred on the Space Shuttle, Mir space station and the International Space Station.
The schedule start and stop times are:
Monday, June 21 – Setup is scheduled to begin at 09:40 UTC (transmissions should start a little later).
Saturday, June 26 – Transmissions are scheduled to end by 18:30 UTC.
The downlink frequency will be 145.800 MHz. Those that recently missed the opportunity during the limited period of MAI experiment 65 transmissions should have numerous chances over the 6 day period to capture many (if not all 12) of the images.
