STS-51-B

STS-51-B was the 17th flight of the NASA Space Shuttle program and the seventh flight of Space Shuttle Challenger. The launch of Challenger on April 29, 1985, was delayed by 2 minutes and 18 seconds, due to a launch processing failure. Challenger was initially rolled out to the pad to launch on the STS-51-E mission. The shuttle was rolled back when a timing issue emerged with the TDRS-B satellite. When STS-51-E was canceled, Challenger was remanifested with the STS-51-B payloads. The shuttle landed successfully on May 6, 1985, after a week-long mission.
