EVAtion ------------------------------------------------------------------------ Full Description Mission Specialist Bruce McCandless II, is seen further away from the confines and safety of his ship than any previous astronaut has ever been. This space first was made possible by the Manned Manuevering Unit or MMU, a nitrogen jet propelled backpack. After a series of test maneuvers inside and above Challenger's payload bay, McCandless went "free-flying" to a distance of 320 feet away from the Orbiter. This stunning orbital panorama view shows McCandless out there amongst the black and blue of Earth and space. ------------------------------------------------------------------------ Keywords STS-41B Challenger Manned Maneuvering Unit MMU Bruce McCandless Extravehicular Activity EVA Spacewalk ------------------------------------------------------------------------ Subject Category Space Shuttle, EVAs-Spacewalk, ------------------------------------------------------------------------ Reference Numbers * Center: JSC * Center Number: S84-27031 * GRIN DataBase Number: GPN-2000-001087 ------------------------------------------------------------------------ Source Information * Creator/Photographer: NASA * Original Source: DIGITAL ------------------------------------------------------------------------ Image Information ( Copyright Notification )
