Francis R. Scobee
Commander

Dick Scobee was Born May 19, 1939, in Cle Elum, Washington. Scobee joined the Air Force in 1957, served a combat tour in Vietnam and flew as a test pilot before joining NASA in 1978.

His first flight came in 1984, as pilot on the STS 41-C mission. During this seven-day flight the crew retrieved the ailing Solar Maximum Satellite, repaired it and replaced it in orbit. The mission also included flight tests of Manned Maneuvering Unit backpack in two spacewalks.

Michael J. Smith
(Captain, USN)
Pilot

Michael Smith was born April 30, 1945, in Beaufort, North Carolina. A graduate of the United States Naval Academy, Smith served in Vietnam before becoming a test pilot.

He joined NASA's astronaut corps in 1980 and served as a commander in the Shuttle Avionics Integration Laboratory. Challenger was his first spaceflight.

Judith Resnik was born April 5, 1949, in Akron, Ohio. She was a classical pianist and also enjoyed bicycling, running, and flying during her free time. Before joining NASA, Resnik worked on circuit design and was a biomedical engineer.

She joined NASA in January 1978 and first flew as a mission specialist on STS 41-D in August 1984, on the maiden flight of the shuttle Discovery. The crew earned the name "Icebusters" for successfully removing hazardous ice particles from the shuttle using the robot arm.

McNair joined NASA in January 1978 and first flew as a mission specialist on STS 41-B in 1984. The crew deployed two communications satellites, made the first flight test of the Manned Maneuvering Unit backpack and used the Canadian robot arm -- operated by McNair -- to position spacewalking astronauts in the payload bay for the first time.
