McCandless was a mission specialist on the tenth Space Shuttle Mission (41-B) which launched from Kennedy Space Center, Florida, on February 3, 1984. He was accompanied by Mr. Vance Brand, spacecraft commander, Commander Robert L. Gibson, pilot, and fellow mission specialists, Dr. Ronald E. McNair, and Lt. Col. Robert L. Stewart. The flight accomplished the proper shuttle deployment of two Hughes 376-series communications satellites. Rendezvous sensors and computer programs were flight tested for the first time. This mission marked the first checkout of the Manned Maneuvering Unit (MMU), and Manipulator Foot Restraint (MFR). McCandless made the first, untethered, free flight on each of the two MMU's carried on board and alternated with Stewart in the activities constituting two spectacular extravehicular activities (EVAS). The German Shuttle Pallet Satellite (SPAS), Remote Manipulator System (RMS), six Getaway Specials, and materials processing experiments were included on the mission. The 8 day orbital flight of Challenger (OV-099) culminated in the first landing on the runway at the Kennedy Space Center on February 11, 1984. With the completion of this flight McCandless logged a total of 191 hours in space (including 4 hours of MMU flight time).
More recently, McCandless was a mission specialist on the crew of STS-31, which launched on April 24, 1990, from the Kennedy Space Center in Florida. Crew members aboard Space Shuttle Discovery included Col. Loren J. Shriver, USAF, (spacecraft commander), Col. Charles F. Bolden, USMC, (pilot), and Drs. Steven A. Hawley and Kathryn D. Sullivan (mission specialists). During this 5 day mission, crew members deployed the Hubble Space Telescope, and conducted a variety of cameras, including both the IMAX in cabin and cargo bay cameras, for earth observations from their record setting altitude of 380 miles. Following 76 orbits of the earth in 121 hours, STS-31 Discovery landed at Edwards Air Force Base, California, on April 29, 1990.
With the completion of his second mission, McCandless has logged a total of 312 hours in space.
