Physiological Variables of EVA Participants--An Update (LSAHNEWSV11_1)
Research Area:
Cardiovascular physiology
Clinical medicine
Pulmonary physiology
Species Studied
Scientific Name: Homo sapiens Species: Human

The physiological variables of extravehicular activity (EVA) participants were first explored in the October 1998 issue of the LSAH Newsletter. This initial article investigated EVA participants within the Shuttle program, up to January 1998. Between then and December 2001, 26 additional EVAs within 12 missions have been performed. All but three of these EVAs were performed in support of assembly and maintenance of the International Space Station. As this assembly and maintenance process is a continual one, many more EVAs will have to be performed in the future.
