STS061-74-046 (7 Dec 1993) --- Anchored on the end of the Space Shuttle Endeavour's Remote Manipulator System (RMS) arm, astronaut Jeffrey A. Hoffman (foreground) prepares to install the new Wide Field\Planetary Camera (WFPC II) into the empty cavity (top left) on the Hubble Space Telescope (HST).  WFPC I is seen temporarily stowed at bottom right.  Astronaut F. Story Musgrave works with a Portable Foot Restraint (PFR) at frame center, as his image is reflected in the shiny surface of the telescope.  Hoffman and Musgrave shared chores on three of the five extravehicular activity?s (EVA) during the mission.

STS100-714-027 (19 April-1 May 2001) --- Astronaut Chris A. Hadfield, mission specialist representing the Canadian Space Agency (CSA), stands on the portable foot restraint (PFR) connected to the Endeavour's remote manipulator system (RMS) robotic arm, during one of the two days of extravehicular activity (EVA) on the STS-100 mission. Astronaut Scott E. Parazynski, mission specialist, is seen at left near the Spacelab pallet.

STS100-333-028 (19 April-1 May 2001) --- Astronaut Chris A. Hadfield, STS-100 mission specialist representing the Canadian Space Agency (CSA), stands on the portable foot restraint (PFR) connected to the Endeavour's remote manipulator system (RMS) robotic arm, using an International Space Station (ISS) pistol grip tool during one of two days of extravehicular activity (EVA).

The darkness of space forms the backdrop for this extravehicular activity (EVA) scene captured by one of the STS-57 crewmembers in Endeavour's, Orbiter Vehicle (OV) 105's, crew cabin. Pictured near the recently "captured" European Retrievable Carrier (EURECA) at frame center is Mission Specialist (MS) and Payload Commander (PLC) G. David Low. Suited in an extravehicular mobility unit (EMU), Low, anchored to the remote manipulator system (RMS) via a portable foot restraint (PFR) (manipulator foot restraint (MFR)), is conducting Detailed Test Objective (DTO) 1210 procedures. Specifically, this activity will assist in refining several procedures being developed to service the Hubble Space Telescope (HST) on mission STS-61 in December 1993. The PFR is attached to the RMS end effector via a PFR attachment device (PAD). Partially visible in the foreground is the Superfluid Helium Onorbit Transfer (SHOOT) payload.

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

STS049-91-029 (13 May 1992) --- Following the successful capture of Intelsat VI satellite, three astronauts continue their chores toward moving the 4.5 ton communications satellite into the space shuttle Endeavour's cargo bay. A fellow crew member recorded this 70mm still frame from inside Endeavour's cabin. Left to right, astronauts Richard J. Hieb, Thomas D. Akers and Pierre J. Thuot, cooperate on the effort to attach a specially designed grapple bar underneath the satellite. Thuot stands on the end of the Remote Manipulator System's (RMS) arm while Hieb and Akers are on Portable Foot Restraints (PFR) affixed to Endeavour's portside and the Multipurpose Support Structure (MPESS), respectively. The sections of Earth which form the backdrop for the scene are blanketed with thousands of square miles of clouds. Photo credit: NASA
