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.
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. ==Post-NASA career==
