STS-29 was a NASA Space Shuttle mission, during which Space Shuttle Discovery inserted a Tracking and Data Relay Satellite (TDRS) into Earth's orbit. It was the third shuttle mission following the Challenger disaster of 1986, and launched from Kennedy Space Center, Florida, on 13 March 1989. STS-29 was the eighth flight of Discovery and the 28th Space Shuttle mission overall; its planned predecessor, STS-28, was delayed until August 1989.
