He has logged 3,300 hours flying time, the majority in jet aircraft.
NASA career
Dr. Van Hoften was selected as an astronaut candidate by NASA in January 1978. He completed a 1-year training and evaluation period in August 1979.
From 1979 through the first flight, STS-1, Van Hoften supported the Space Shuttle entry and on-orbit guidance, navigation and flight control testing at the Flight Systems Laboratory at Downey, California. Subsequently, he was lead of the Astronaut Support Team at Kennedy Space Center, Florida, responsible for the Space Shuttle turn-around testing and flight preparations. He served as a mission specialist on STS-41-C in 1984, and STS-51-I in 1985. Dr. Van Hoften has logged a total 338 hours in space, including 22 hours of EVA flight time.
Spaceflight experience
STS-41-C: Challenger (April 6–13, 1984) was launched from the Kennedy Space Center, Florida, and returned to land at Edwards Air Force Base, California. During the 7-day mission the crew successfully deployed the Long Duration Exposure Facility (LDEF); retrieved the ailing Solar Maximum Mission satellite, repaired it on board the orbiting Challenger and replaced it in orbit, using the robot arm called the Remote Manipulator System (RMS). The mission also included flight testing of Manned Maneuvering Units (MMU's) in two extra-vehicular activities (EVA's); operation of the Cinema 360 and IMAX Camera Systems, as well as a Bee Hive Honeycomb Structures student experiment. The mission was accomplished in 107 Earth orbits in 167 hours, 40 minutes, 7 seconds.[2]
STS-51-I: Discovery (August 27 to September 3, 1985) launched from the Kennedy Space Center, Florida, and returned to land at Edwards Air Force Base, California. During this mission, the crew successfully deployed three communications satellites, the Navy's Syncom IV-4, Australian AUSSAT, and American Satellite Company's ASC-1. The crew also performed the successful salvage of the ailing Navy Syncom IV-3 satellite. These tasks included two extravehicular activities (EVA's) in which Dr. Van Hoften attached to the Remote Manipulator System (RMS) performed the first manual grapple and manual deployment of a satellite in orbit. The mission also included the Physical Vapor Transport of Organic Solids (PVTOS), the second material processing experiment to be flown aboard a Shuttle for 3M. The mission was accomplished in 112 orbits of the Earth in 171 hours, 17 minutes, 42 seconds.[2]
