41C-02-067 (6-13 April 1984) --- One of the first major accomplishments of Flight 41-C?s crew aboard the Challenger was to place this giant satellite into Earth orbit. Still attached to the remote manipulator system (RMS) end effector, the Long-Duration Exposure Facility (LDEF) is backdropped against Florida, the Bahama Bank, the Gulf of Mexico and Atlantic waters. The multi-colored cylinder carries 50-odd passive scientific experiments representing 194 investigators from around world. The LDEF program is directed by the Langley Research Center in Hampton, Virginia. The facility will be retrieved in a little less than a year by a Space Shuttle crew. This frame was one of the visuals used by the 41-C astronauts for their April 24, 1984 post-flight press conference. Cape Canaveral, where this seven-day mission got its start, and Lake Okeechobee, are easily recognized in the frame, photographed shortly before 11:30 a.m. (CST), April 7, 1984.
