In this historical photo from the U.S. space agency on June 25, 1993, backdropped against the blue and white Earth, Mission Specialist (MS) and Payload Commander (PLC) G. David Low and (MS) Peter J.K. Wisoff, wearing Extravehicular Mobility Units (EMUs), simulate handling of large components in space.

Above Endeavour's Payload Bay (PLB), Low, anchored by a Portable Foot Restraint (PFR) Manipulator Foot Restraint (MFR) on the Remote Manipulator System (RMS) end effector, maneuvers Wisoff, representing the mass of a large space component. This particular task was rehearsed with eyes toward the servicing of the Hubble Space Telescope (HST) or the assembly and maintenance of Space Station.

This Extravehicular Activity (EVA), Detailed Test Objective (DTO) was conducted both with and without intentional disturbances from Endeavour's thrusters and movements of the RMS.

The SPACEHAB-01 Commercial Middeck Augmentation Module (CMAM)) is visible in the foreground with the Superfluid Helium On Orbit Transfer (SHOOT) payload liquid helium dewar assembly and the European Retrievable Carrier (EURECA) only partially visible in the aft PLB shadows. The vertical stabilizer and Orbital Maneuvering System (OMS) pods are silhouetted against the Earth's surface.
