STS-26 was the 26th NASA Space Shuttle mission and the seventh flight of the Discovery orbiter. The mission launched from Kennedy Space Center, Florida, on 29 September 1988, and landed four days later on 3 October. STS-26 was declared the "Return to Flight" mission, being the first mission after the Space Shuttle Challenger disaster of 28 January 1986. It was the first mission since STS-9 to use the original STS numbering system, the first to have all its crew members wearing pressure suits for launch and landing since STS-4, and the first mission with bail-out capacity since STS-3. STS-26 was also the first all-veteran crew mission since Apollo 11, with all of its crew members having flown at least one prior mission.

Space Shuttle Discovery lifted off from Pad B, Launch Complex 39, Kennedy Space Center, at 11:37 am EDT on 29 September 1988, 975 days after the Challenger disaster. The launch was delayed by one hour and 38 minutes due to unseasonable and unusual light winds, and the need to replace fuses in the cooling systems of two crew members' flight suits. The suits were repaired, and a waiver was issued for the wind conditions after officials determined there was a sufficient safety margin for wind loads on the orbiter's wing leading edges. The shuttle crew, all veteran astronauts, included Commander Frederick H. "Rick" Hauck, Pilot Richard O. Covey, and Mission Specialists John M. "Mike" Lounge, George D. "Pinky" Nelson and David C. Hilmers.
