ARISSat-1 On the Air for Gagarin Anniversary

To celebrate the 50th anniversary of the first human spaceflight by cosmonaut Yuri Gagarin, the ARISSat-1 satellite aboard the International Space Station will be on the air using the station’s external antenna. Transmissions will begin on Monday, April 11, at 14:30 UTC and continue until 10:30 UTC on April 13. To preserve the satellite’s battery, transmissions will cycle on and off. ARISSat-1 will transmit for 40 to 60 seconds, and then remain silent for 2 minutes. The FM transmissions on 145.950 MHz will alternate between a voice ID, telemetry values, SSTV images and audio greetings in 15 different languages. One of the transmissions will contain audio of a conversation between Gagarin and ground controllers that was recorded during the historic flight. More
