S61-E-018 (6 Dec 1993) --- Astronaut Jeffrey A. Hoffman, anchored to a foot restraint on the end of the Remote Manipulator System (RMS) arm, inserts the new Wide Field/Planetary Camera (WFPC-II) into its place on the Hubble Space Telescope (HST). Astronaut F. Story Musgrave, who shared the duties of replacing the camera, is partially visible at right edge of frame. Electronic still photography is a relatively new technology which provides the means for a handheld camera to electronically capture and digitize an image with resolution approaching film quality. The electronic still camera has flown as an experiment on several other shuttle missions.
