Astronaut Gregory Jarvis gets a familiarization session in weightlessness aboard a KC-135 "zero gravity" aircraft. Jarvis was originally assigned as payload specialist to STS-51D but was reassigned to STS-51L. Gregory Bruce Jarvis (August 24, 1944 - January 28, 1986) was an American engineer who died during the destruction of the Space Shuttle Challenger on mission STS-51-L, where he was serving as Payload Specialist. The remains of all seven astronauts from the Challenger disaster were discovered in the crew decks on the ocean floor. Jarvis' body was discovered in the lower mid-deck along with Ronald McNair and Christa McAuliffe. During salvage operations to raise the crew deck from the ocean floor, it escaped from the wreckage, floated to the surface, and disappeared back into the sea. In 2004, Jarvis was posthumously awarded the Congressional Space Medal of Honor.
