Group program missions to the moon and Mars will include as many as 24 hours of EVA per crew member per week, which will involve the performance of exploration, science, construction, and maintenance tasks. The effectiveness and success of these missions is dependent on designing EVA systems and protocols that maximize human performance and efficiency while minimizing health and safety risks for crew members.It is very importantl to understand the effects of EVA system design variables such as suit pressure, weight/ mass, joint ranges of motion, and biomedical monitoring on the ability of astronauts to perform safe, efficient, and effective EVAs.
