David C. Hilmers - Space Flight Experience

Space Flight Experience

STS-51-J Atlantis, a classified Department of Defense mission, launched from Kennedy Space Center, Florida, on October 3, 1985. This was the maiden voyage of the Orbiter Atlantis. Hilmers had prime responsibility for a number of on-orbit activities during the mission. After 98 hours of orbital operations, Atlantis landed at Edwards Air Force Base, California, on October 7, 1985.

STS-26 Discovery, the first mission to be flown after the Challenger accident, was launched from the Kennedy Space Center, Florida, on September 29, 1988. During the four-day mission, the crew successfully deployed the Tracking and Data Relay Satellite (TDRS-C), which was subsequently carried to orbit by the Inertial Upper Stage (IUS) rocket. They also operated eleven mid-deck experiments. Discovery completed 64 orbits of the Earth before landing at Edwards Air Force Base, California, on October 3, 1988.

STS-36 Atlantis launched from the Kennedy Space Center, Florida, on February 28, 1990. This mission carried Department of Defense payloads and a number of secondary payloads. After 72 orbits of the Earth, the STS-36 mission concluded with a lakebed landing at Edwards Air Force Base, California, on March 4, 1990, after traveling 1.87 million miles.

STS-42 Discovery launched from the Kennedy Space Center, Florida, on January 22, 1992. Fifty-five major experiments conducted in the International Microgravity Laboratory-1 module were provided by investigators from eleven countries, and represented a broad spectrum of scientific disciplines. During 128 orbits of the Earth, the STS-42 crew accomplished the mission's primary objective of investigating the effects of microgravity on materials processing and life sciences. In this unique laboratory in space, crew members worked around-the-clock in two shifts. Experiments investigated the microgravity effects on the growth of protein and semiconductor crystals. Biological experiments on the effects of zero gravity on plants, tissues, bacteria, insects and human vestibular response were also conducted. This eight-day mission culminated in a landing at Edwards Air Force Base, California, on January 30, 1992.
