STS051-98-021 (16 Sept. 1993) --- In the Space Shuttle Discovery's aft cargo bay, astronaut Carl E. Walz gets his turn on the Portable Foot Restraint (PFR). Astronauts Walz, waving to his crew mates inside Discovery's cabin, and James H. Newman each put in some time evaluating the PFR, one of the pieces of gear to be used on the Hubble Space Telescope (HST) STS-61 servicing mission (scheduled later this year) and other Shuttle missions.

S84-27024 (7 Feb 1984) --- This 70mm frame centers on a foot restraint that strayed from the Earth-orbiting Space Shuttle Challenger during the February 9, 1984 extravehicular activity (EVA) session of astronauts Bruce McCandless II and Robert Stewart. As seen in JSC photograph frame number S84-27025, McCandless goes after the piece. Not pictured is Vance D. Brand, crew commander, who moved the spacecraft nearer the object.

S84-27021 (7 Feb 1984) --- Astronaut Bruce McCandless II, 41B mission specialist tests a "cherry-picker" type device during February 7 historical Extravehicular Activity (EVA). The EVA, in which Astronauts McCandless and Robert L. Stewart, two of three STS-41B mission specialists, participated, marked two firsts--initial use of both the Mobile Foot Restraint (MFR) attached to the Remote Manipulator System (RMS) arm here, and the Manned Maneuvering Unit (MMU) backpack (not seen in this frame). The Challenger was flying with its aft end aimed toward the Earth. This photograph clearly shows where the MFR connects to the end effector of the Canadian-built RMS arm. The two spacewalkers were monitored and photographed by their fellow crewmembers, astronauts Vance D. Brand, commander; Robert L. Gibson, pilot; and Ronald E. McNair, mission specialist. The three remained in the cabin for another EVA session two days later. Photo Credit: NASA

S131-E-009455 (13 April 2010) --- Dwarfed by space shuttle Discovery, NASA astronauts Rick Mastracchio (right) and Clayton Anderson, both STS-131 mission specialists, are seen working in Discovery’s aft payload bay during the mission's third and final session of extravehicular activity (EVA) as construction and maintenance continue on the International Space Station. During the six-hour, 24-minute spacewalk, Mastracchio and Anderson hooked up fluid lines of the new 1,700-pound tank, retrieved some micrometeoroid shields from the Quest airlock’s exterior, relocated a portable foot restraint and prepared cables on the Zenith 1 truss for a spare Space to Ground Ku-Band antenna, two chores required before space shuttle Atlantis' STS-132/ULF-4 mission in May. Earth’s horizon and the blackness of space provide the backdrop for the scene.
