On July 20, AMSAT will mark the 40th anniversary of the first manned lunar landing with a special event on the AO-51 amateur radio satellite. During evening passes in the U.S. and Europe, AO-51 will transmit a message commemorating the event. The message will be transmitted on the 435.300 MHz FM downlink and will contain a Robot 36 SSTV image as well as a voice message.
