STS077-716-050 (19-29 May 1996) --- With part of the Pacific Ocean and almost the entire state of California as a backdrop, this scene of the Space Shuttle Endeavour’s cargo bay was photographed by a crew member on the aft flight deck. Spacehab-4’s module is in the foreground, flanked by the Canadian-built Remote Manipulator System (RMS) arm and the Spartan-207 payload, both in stowed position. Sunglint on the Earth scene accentuates the bay area of San Francisco. The San Andreas Fault can also easily be traced not far inalnd from the coastline.

STS043-83-082 (2-11 Aug 1991) --- Having bade farewell to its Tracking and Data Relay Satellite/IUS payload, Atlantis' cargo bay appears somewhat vacant in this scene, backdropped over the southern two-thirds of the Florida peninsula. Important activity in the payload bay continues, however, with the operation of Space Station Heat Pipe Advanced Radiator Element (SHARE II), an experiment carried on the starboard side (lower left quadrant of frame). Purpose of the SHARE experiment is to demonstrate microgravity thermal vacuum performance of a heat pipe radiator for heat rejection as a prelude to development of a Space Station heat rejection system. The foil covered ring and horseshoe shaped objects aft in the payload bay served as restraint devices for the TDRS-E prior to its deployment six hours after Atlantis lifted off from Kennedy Space Center's Launch Pad 39A.

STS043-72-059 (2 Aug 1991) --- The Tracking and Data Relay Satellite (TDRS-E), leaves the payload bay of the earth-orbiting Atlantis a mere six hours after the Space Shuttle was launched from Pad 39A at Kennedy Space Center, Florida. TDRS, built by TRW, will be placed in a geosynchronous orbit and after on-orbit testing, which requires several weeks, will be designated TDRS-5. The communications satellite will replace TDRS-3 at 174 degrees West longitude. The backbone of NASA's space-to-ground communications, the Tracking and Data Relay satellites have increased NASA's ability to send and receive data to spacecraft in low-earth orbit to more than 85 percent of the time. The five astronauts of the STS 43 mission are John E. Blaha, mission commander, Michael A. Baker, pilot, and Shannon W. Lucid, G. David Low, and James C. Adamson, all mission specialists.

STS073-736-018 (29 October 1995) --- The Kalahari Desert in Namibia, Africa, forms the backdrop for this scene. Five NASA astronauts and two guest researchers spent almost 16 days of research in this science module affixed in the payload bay of the Space Shuttle Columbia in Earth-orbit. The tunnel in bottom foreground served as the busy passageway for the seven crew members, who split their forces into two shifts. The Nosob and Olifants Rivers can be delineated in the terrain below.

41G-101-013 (14 Oct 1984) --- Astronaut David C. Leestma works at the Orbital Refueling System (ORS) on the Mission Peculiar Support Structure (MPESS) in the aft end of the cargo bay of the Space Shuttle Challenger. Astronaut Kathryn D. Sullivan, America's first woman to perform an extravehicular activity (EVA) with the logging of this busy day, exposed this frame witha 35mm camera. The crew consisted of astronauts Robert L. Crippen, commander; Jon A. McBride, pilot; mission specialist's Kathryn D. Sullivan, Sally K. Ride, and David D. Leestma; Canadian astronaut Marc Garneau; and Paul D. Scully-Power, payload specialist. EDITOR'S NOTE: The STS-41G mission had the first American female EVA (Sullivan); first seven-person crew; first orbital fuel transfer; and the first Canadian (Garneau).

STS087-752-023 (19 November – 5 December 1997) --- This picture of Columbia's cargo bay, taken through the aft flight deck windows with a handheld 70mm camera, shows the U.S. Microgravity Payload (USMP-4) mission's cargo.
