SuitSat (also known as SuitSat-1, Mr. Smith, Ivan Ivanovich, RadioSkaf, Radio Sputnik, and AMSAT-OSCAR 54) was a retired Russian Orlan space suit with a radio transmitter mounted on its helmet, used as a hand-launched satellite.
First devised around 2004, SuitSat-1 was deployed in an ephemeral orbit around the Earth from the International Space Station on February 3, 2006. Contact from SuitSat-1 was lost by February 18, and the satellite burned up on reentry in Earth's atmosphere on September 7.
A similar hand-launched satellite, Kedr, was released in 2011 and was initially named SuitSat-2, despite not using a space suit.
