To commemorate the 40th anniversary of the Apollo-Soyuz mission, the Amateur Radio on the International Space Station (ARISS) team will transmit a series of 12 Slow Scan Television (SSTV) images. The SSTV transmissions 145.80 MHz will begin on the morning of Saturday, July 18, and continue through Sunday July 19, subject to change. Apollo-Soyuz represented the first joint US-USSR mission, and it set the stage for later US-Russia collaboration on the space shuttle, Mir Space Station, and the International Space Station.
“The Apollo-Soyuz Test Project would send NASA astronauts Tom Stafford, Deke Slayton and Vance Brand in an Apollo Command and Service Module to meet Russian cosmonauts Aleksey Leonov and Valeriy Kubasov in a Soyuz capsule,” NASA has recounted. “A jointly designed, US-built docking module fulfilled the main technical goal of the mission, demonstrating that two dissimilar craft could dock in orbit. But the human side of the mission went far beyond that.”
The Soyuz and Apollo vehicles were docked from July 17-19, 1975. During that time, the three US astronauts and two USSR cosmonauts carried out experiments and other activities. Apollo-Soyuz was the final mission of the Apollo program and the last US human spaceflight mission prior to the inaugural space shuttle mission in 1981.
The ISS cosmonauts will take time out from the SSTV transmissions on July 18 to conduct an ARISS contact (starting at approximately 1655 UTC) with students attending the Moon Day/Frontiers of Flight Museum event in Dallas, Texas. Streaming audio will be available.
