Description

Initial State of Gap: Previous studies have shown that the most profound sensorimotor deficits occur during and after gravitational transitions. Given these changes there is a possibility that crew will experience impaired control of the spacecraft during landing along with impaired ability to immediately egress following a landing on a planetary surface (Earth or other) after long-duration space flight. Data are required that define changes in sensorimotor function and operational performance deficits particularly for the period soon after landing on a planetary surface. 

Target for Gap Closure: Define the magnitude of change and time course of recovery for sensorimotor function after a spaceflight mission; including balance control, locomotor control, gaze control, eye-head-hand coordination, and spatial perception. Determine if these changes impact functional performance of critical mission tasks.

Interim steps:
1.Conduct data mining activities to review existing sensorimotor performance data collected during/after spaceflight.
2.Conduct flight and ground studies to examine sensorimotor function before/during/after exposure to varying gravitational environments.
3.Develop and conduct a set of sensorimotor tests soon after landing following a long-duration spaceflight at remote testing sites.
4.Update the evidence report and NASA standards with information defining the acceptable level of sensorimotor risk based on functional performance thresholds below which task performance is impaired.
5.Use evidence acquired to address sensorimotor gaps SM24 and SM28.

Approach: Conduct a series of tests that examine both sensorimotor changes and potential operational deficits. Develop and implement a set of sensorimotor tests that are short in duration and easy to implement soon after landing following a long-duration spaceflight at remote testing sites like that experienced by the Soyuz landing. 

Target for Closure
Define the magnitude of change and time course of recovery for sensorimotor function after a spaceflight mission; including balance control, locomotor control, gaze control, eye-head-hand coordination, and spatial perception. Determine if these changes impact functional performance of critical mission tasks.
