STS007-08-396 (18-24 June 1983) --- Astronaut Robert L. Crippen, STS-7 commander, used a 35mm camera to expose this frame of the four representatives of the "thirty five new guys" onboard the Earth-orbiting Space Shuttle Challenger. The TFNG (notice Frederick H. Hauck's T-shirt at left) pays tribute to the 1978 astronaut candidate (ASCAN) class of NASA astronauts. Others in the photograph are Astronauts Norman E. Thagard, Sally K. Ride and John M. Fabian. Hauck is the crew's pilot and the other three are mission specialist. The crew members are in the process of preparing a snack of meal. The tall experiment in the background is the Continuous Flow Electrophoresis System (CFES).

CAPE CANAVERAL, Fla. -- This orbiter tribute of space shuttle Challenger, or OV-099, hangs in Firing Room 4 of the Launch Control Center at NASA's Kennedy Space Center in Florida. Challenger's accomplishments include the first night launch and first African-American in space, Guion Bluford, on STS-8, the first in-flight capture, repair and redeployment of an orbiting satellite during STS-41C, the first American woman in space, Sally Ride, on STS-7, and the first American woman to walk in space, Kathryn Sullivan, during STS-41G. Challenger is credited with blazing a trail for NASA's other orbiters with the first night landing at Edwards Air Force Base in California on STS-8 and the first landing at Kennedy on STS-41B. The spacewalker in the tribute represents Challenger’s role in the first spacewalk during STS-6 and the first untethered spacewalk on STS-41B. Crew-designed patches for each of Challenger’s missions lead from Earth toward a remembrance of the STS-51L crew, which was lost 73 seconds after liftoff on Jan. 28, 1986. Five orbiter tributes are on display in the firing room, representing Atlantis, Challenger, Columbia, Endeavour and Discovery. Graphic design credit: NASA/Lynda Brammer
