51D-04-015 (15 April 1985) --- Astronaut Rhea Seddon and Karol J. Bobko continue work on snag-type extension for the Remote Manipulator System (RMS) as part of an effort to activate a lever on a troubled communications satellite. Since the crew learned soon after deployment of the Syncom IV (LEASAT) spacecraft that it was not functioning properly plans were formulated for a rendezvous in space between the Discovery and the satellite. A fly swatter-like extension and another resembling a LaCrosse stick were fashioned from onboard supplies and furnishings. Stowage lockers nearby serve as a work bench for the two. At various times during the seven-day mission, the majority of the seven-member crew participated in the tool-making and preparations for an extravehicular activity (EVA) by the flights other two mission specialists -- Jeffrey A. Hoffman and S. David Griggs -- to connect the two tools to the RMS. Bobko is mission commander and Dr. Seddon, a mission specialist.

51J-S-001 (3 Oct 1985) --- This 35mm frame was taken moments after the Space Shuttle Atlantis cleared the launch tower to begin its first mission in space. Onboard, ready to carry out STS-51J mission were astronauts Karol J. Bobko, commander; Ronald J. Grabe, pilot; Robert L. Stewart and David C. Hilmers, mission specialist; and United States Air Force Major William A. Pailes, payload specialist.

S86-25196 (January 1986) --- Sharon Christa McAuliffe, STS-51L citizen observer/payload specialist, gets a preview of microgravity during a special flight aboard NASA?s KC-135 ?zero gravity? aircraft. McAuliffe will represent the Teacher-in-Space Project aboard the space shuttle Challenger when it launches later this month. This photograph was taken by Keith Meyers of the New York Times. EDITOR?S NOTE: The STS-51L crew members lost their lives in the space shuttle Challenger accident moments after launch on Jan. 28, 1986 from the Kennedy Space Center (KSC). Photo credit: NASA

51I-32-059 (27 August 1985) --- The American Satellite Company (ASC) communications satellite rises from the cargo bay at 6:54 a.m. August 27, 1985.

S85-37165 (8-12 July 1985) -- Sharon C. (Christa) McAuliffe of Concord High, Concord, New Hampshire, runs in place on treadmill to test physiological responses at Johnson Space Center. Christa McAuliffe was eventually chosen as the first Teacher in Space and was a member of the seven-member Challenger shuttle crew which died tragically in the explosion of the spacecraft during the launch of STS-51L from the Kennedy Space Center about 11:40 a.m., EST, on Jan. 28, 1986. The explosion occurred 73 seconds into the flight as a result of a leak in one of two Solid Rocket Boosters that ignited the main liquid fuel tank. The crew members of the Challenger represented a cross-section of the American population in terms of race, gender, geography, background, and religion. The explosion became one of the most significant events of the 1980s, as billions around the world saw the accident on television and empathized with any one of the several crew members killed.

51F-03-024 (29 July-6 Aug 1985) --- Astronauts Anthony W. England, left, and Roy D. Bridges are surrounded by some of the prolific teleprinter copy transmitted from ground controllers to the Earth-orbiting Challenger. Eventually the equivalent of several football fields' length of paper was filled with data from flight controllers.

51D-07-003 (12-19 April 1985) --- Astronaut Rhea Seddon begins early work on a fly swatter-like snagging device to be used as an extension to the Remote Manipulator System (RMS) arm on Discovery for an April 17, 1985 attempt to trip a lever on the troubled Syncom-IV satellite.

Family and friends of the STS 51-L crew prepare to be seated at the Memorial service at JSC. In the center of the view appears to be the family of Astronaut Ellison Onizuka.

S86-25182 (for release January 1986) --- Sharon Christa McAuliffe, STS-51L citizen observer/payload specialist, prepares to remove her helmet after participating in emergency egress training in the shuttle mock-up and integration lab at the Johnson Space Center. McAuliffe will represent the Teacher-in-Space Project aboard the Challenger when it launches in late January. The photo was taken by Keith Meyers of the New York Times. Photo credit: NASA

51C-06-025 (24-27 Jan 1985) --- Astronaut Ellison S. Onizuka, mission specialist, studies flight checklist on middeck of Space Shuttle Discovery.

S86-25186 (December 1985) --- Five members of the prime crew for NASA?s STS-51L mission and a backup crew member are briefed during a training session in the Johnson Space Center?s (JSC) Shuttle Mock-up and Integration Laboratory. From left to right are astronaut Ellison S. Onizuka, mission specialist; Ronald E. McNair, mission specialist; Gregory D. Jarvis, Hughes payload specialist; Judith A. Resnik, mission specialist; Sharon Christa McAuliffe, citizen observer/payload specialist representing the Teacher-in-Space Project; and Barbara R. Morgan, backup payload specialist.

The photograph was taken from special bleachers quickly erected to accommodate hundreds of members of the news media. The audience of thousands was largely made up of JSC employees and family and friends of the Challenger crew members who perished four days earlier in the attempted launch of NASA’s 25th STS mission.
