Jeffrey A. Hoffman (right) and Story Musgrave work near the base of the Hubble Space Telescope (HST) on the first of five spacewalks during the STS-61 mission. Their particular task here is to replace failed Rate Sensor Units (RSUs) inside the telescope's housing. Hoffman is anchored to a foot restraint, mounted on the end of the Space Shuttle Endeavour's Remote Manipulator System (RMS) arm, while Musgrave is standing on a portable foot restraint attached to a support structure in the cargo bay.
