Description

OBJECTIVES:

Critical mission tasks that are required by crews immediately after landing on a planetary surface are seat egress, jump, and walk. To be able to define an effective and comprehensive countermeasure strategy for preserving crew performance during exploration-class missions, there is a need to understand how these functional tasks are actually performed in partial gravity such as on the Moon or Mars. The researchers aim to analyze the execution of four critical mission tasks during the partial gravity and hypergravity phases of parabolic flight by using the same equipment and procedures as those previously used on astronauts returning from International Space Station (ISS) missions and ground-based subjects during axial body unloading.

The goals of this study are (a) to determine the dose-response relationship between the performance of these tasks versus gravity levels between 0 and 1 g; and (b) to identify the vestibular, sensorimotor, and cardiovascular factors that would likely affect their execution.
