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.
The mission's primary payload was a Tracking and Data Relay Satellite (TDRS-D), which became TDRS-4 after deployment, and its attached Inertial Upper Stage (IUS). The satellite was deployed from the shuttle's payload bay less than six hours after launch, at 3:12 am EST. The first-stage orbit burn of the IUS took place an hour later, and the second burn to circularize the orbit occurred 12 hours and 30 minutes into the mission. The satellite was stationed at 41 degrees west longitude.
This patch was executed on a blue twill which gives the illusion of a blue border. Modern embroidery used.
