S84-27020 (7 Feb 1984) --- A fixed camera on astronaut Bruce McCandless II's helmet recorded this rare scene of the Space Shuttle Challenger some 50 to 60 meters away during a history-making extravehicular activity (EVA), February 7, 1984. The Shuttle Pallet Satellite (SPAS-01A) is configured mid-cargo bay. Astronaut Robert L. Stewart, standing beneath the Remote Manipulator System (RMS) arm, later donned the same Manned Maneuvering Unit (MMU) which afforded McCandless the freedom of movement to record this image. Also visible in the cargo bay are the support stations for the two MMU back-packs, the sunshields for the Palapa B and Westar VI Satellites, KU-Band antenna and a number of Getaway Special (GAS) canisters.

S84-27022 (7 Feb 1984) --- A 35mm frame from the February 7, 1984, extravehicular activity (EVA) photographed with a camera affixed to the gear of astronaut Bruce McCandless II. The mission specialist was equipped with the nitrogen-propelled, hand-controlled Manned Maneuvering Unit (MMU), which took him some 90 meters away from the Space Shuttle Challenger. This scene is reminiscent of views of the Challenger during the June 1983, STS-7 flight, on which the Shuttle Pallet Satellite (SPAS - seen here in the middle of the cargo bay) provided scenes of 38-meter-long reusable vehicle over the Earth.

S84-27023 (7 Feb 1984) --- This 70mm frame shows astronaut Bruce McCandless II moving in to conduct a test involving the Trunion Pin Attachment Device (TPAD) he carries and the Shuttle Pallet Satellite (SPAS-01A) partially visible at bottom of frame. SPAS was a stand-in for the damaged Solar Maximum Satellite (SMS) which will be visited for repairs by the STS-41C Shuttle crew in early spring. This particular Extravehicular Activity (EVA) session was a rehearsal for the SMS visit. The test and the actual visit to the SMS both involve the use of jet-powered, hand-controlled Manned Maneuvering Unit (MMU). The one McCandless uses is the second unit to be tested on this flight. Astronaut Robert L. Stewart got a chance to work with both MMU's on the two EVA's.
