Influence of Center of Gravity on Human Performance in Partial Gravity (EPSP_CG)
Principal Investigator
Research Area:
Behavior and performance
Species Studied
Scientific Name: Homo sapiens Species: Human

The Apollo program demonstrated that suit center of gravity (CG) is an important variable affecting human performance in Lunar Extravehicular Activities (EVAs). This study assessed crew performance of representative planetary exploration tasks with a single EVA suit weight with six different CG locations.
