SPACE SHUTTLE DISCOVERY - STS - 51D CREW
Space Shuttle Discovery's STS-51D mission, which launched on April 12, 1985, was the fourth flight of the Discovery orbiter and the sixteenth flight of NASA's Space Shuttle program. The crew of STS-51D comprised seven astronauts, each playing a crucial role in the mission's objectives and operations.
The crew members of STS-51D were:
Karol J. Bobko (Commander): An experienced astronaut, Bobko was on his second spaceflight. He had previously flown on STS-6, the maiden flight of Challenger, and later commanded STS-51D and STS-51J.
Donald E. Williams (Pilot): Williams served as the pilot for this mission. He later commanded STS-34 in 1989, which deployed the Galileo spacecraft to study Jupiter.
M. Rhea Seddon (Mission Specialist): As a physician and one of NASA's first female astronauts, Seddon played a key role in medical experiments and research during the mission. She flew on three Space Shuttle flights during her career.
Jeffrey A. Hoffman (Mission Specialist): An astrophysicist and astronaut, Hoffman was responsible for several scientific experiments on STS-51D. He had a distinguished career with five spaceflights, including repairing the Hubble Space Telescope on STS-61.
S. David Griggs (Mission Specialist): Griggs was a Naval aviator and astronaut, contributing to various mission tasks. He tragically died in an aircraft accident in 1989 before his second scheduled spaceflight.
Charles D. Walker (Payload Specialist): Walker, an engineer, was the first non-government individual to fly in space. He flew as a payload specialist representing McDonnell Douglas Corporation, where he operated the Continuous Flow Electrophoresis System, a pharmaceutical experiment.
E. Jake Garn (Payload Specialist): Garn was a U.S. Senator from Utah and flew as a Congressional observer. He was involved in medical experiments, and his experience helped NASA study space motion sickness; a scale for space sickness was humorously named after him.
The STS-51D mission's primary objectives included deploying two communications satellites, ANIK-C1 for Telesat Canada and SYNCOM IV-3 (also known as LEASAT-3) for the U.S. Navy. However, the mission encountered challenges when LEASAT-3 failed to activate after deployment. This led to an unscheduled spacewalk by Hoffman and Griggs in an attempt to manually activate the satellite.
