Abstract

Extravehicular activity (EVA), or spacewalking, provides astronauts the capability to explore outside of the confines of their spacecraft or habitat. EVA spacesuits must provide pressurization, life support (oxygen to breathe, CO2 removal), thermal, radiation, and debris protection for the astronauts while also enabling exploration through mobile and light weight suits. EVA is a highly complex, potentially hazardous, yet critically important component of human space exploration. Failures during EVA can potentially result in loss of mission, or even loss of life; however, successful EVA enables scientific breakthroughs, advanced technology demonstrations, and iconic human achievements.
