Space Shuttle EVA requirements
Abstract
Description of a Space Shuttle mission and task analysis conducted to derive the requirements for the extravehicular life support system and pressure suit. A baseline extravehicular mobility unit concept that was derived from trade studies to meet these requirements is summarized. It is shown that pressure suits improved over the Apollo and Skylab hardware will be required. Extravehicular activity (EVA) requirements for the Space Shuttle will be highly varied and are expected to average 1.3 hr per flight. About 98% of the EVAs are expected to be of 4-hour duration or less.
