Abstract
The working posture in a 0G environment is quite different from that in a 1G environment. However, the human engineering data cannot always be collected in a 0G environment. Therefore, data for manned space systems is often collected in a 1G environment. In these cases, subjects may have their muscles strained from maintaining the 0G posture. If so, the data is invalidated. This report studied the validity of collecting human engineering data in a 1G environment for the manned space systems. In this experiment, subjects assumed the 0G posture in a 1G environment to compare with their performance with subjects in a 1G posture. These subjects demonstrated better performance with the 0G posture than the subjects in the 1G posture. From this result, it is concluded that collecting human engineering data in a 1G environment for manned space systems is valid.
