Shuttle Extravehicular Mobility Unit (EMU) Operational Enhancements 901317

The NASA/Industry Shuttle EMU team initiated an EMU program activity in 1988 to reduce EMU criticality 1 failure causes, reduce ground operations costs, and also to enhance on-orbit operational Extravehicular Activity (EVA) capability. Replacement/refurbishment hardware is being developed, certified, and delivered. System level life extention testing is expected to extend the Life Limited Components replacement schedule. Goals of this program are to achieve a 25 percent reduction in ground turn-around man-hours and processing time between missions and to extend Extravehicular Activity (EVA) on-orbit capabilities expected to be necessary to support Space Station Freedom assembly and contingency EVA operations. This paper identifies and describes tasks being implemented with expected benefits to NASA-manned spaceflight programs.
