Spacewalk. Against the backdrop of a cloudy Earth, astronaut Michael L. Gernhardt, mission specialist, stands on a mobile foot restraint attached to Space Shuttle Endeavour by a remote manipulator arm. Note the reflection of the shuttle nose in his visor. This photograph was taken during mission STS69 (718 September 1995) while Gernhardt tested new tools and spacesuit accessories designed for use on board space stations.
