Classics in space medicine: Motion performance of pressure-suited subjects under zero and lunar gravity conditions.

摘要

This Classic study used parabolic flight to assess how weightlessness (0-G) or lunar gravity (0.17-G) while wearing a pressurized space suit might affect human locomotion from one module to another in space. Ten subjects propelled themselves from one seat through an adjustable iris to another seat wearing coveralls or an inflated pressure suit. Variables under study included iris diameter, maneuvering style (head- or feet-first) and the location of hand-holds. Each subject completed 48 trials in a partially counterbalanced fixed factorial design over the course of two flights in the same C-131B aircraft that was used for training Project Mercury astronauts. No 1-G comparison was possible due to the completely different nature of the required motion.
