40 Years Ago: STS-41B, the First Flight of the Manned Maneuvering Unit | Simple Site

On Feb. 3, 1984, space shuttle Challenger took off on its fourth flight, STS-41B. Its five-person crew of Commander Vance D. Brand, Pilot Robert L. “Hoot” Gibson, and Mission Specialists Ronald E. McNair, Robert L. Stewart, and Bruce McCandless flew an eight-day mission ending with the first return to NASA’s Kennedy Space Center (KSC) in […]
