HST Astronauts: SM 2 EVA

This wide-angle shot of the Hubble Space Telescope in the Space Shuttle Discovery’s cargo bay, backdropped against Australia, was taken during the fifth extravehicular activity (EVA) added to complete servicing of the orbiting observatory. Steven L. Smith (center frame) and Mark C. Lee (on the Remote Manipulator System, or RMS, arm) conducted a survey of the hand rails on Hubble. In the foreground is the hatchway of the airlock that connects the airless payload bay to the shirt-sleeve environment of Discovery’s crew cabin.
