Climbing on Mars

Pacific Spaceflight is field testing ideas for Mars suits.
 
“We bet a lot of early Mars climbing will be like nineteenth-century mountaineering—scrambling/third class/5.0 stuff where robots can’t go, or aid climbing with some crazy rack of tools.”

Humans to Mars Report 2018

“The Humans to Mars Report (H2MR) is an annual publication that presents a snapshot of current progress in mission architectures, science, domestic and international policy, human factors, and public perception regarding human missions to Mars – and highlights progress and challenges from year to year. By doing so, H2MR provides stakeholders and policy makers with an invaluable resource to assist them in making decisions that are based on current facts rather than on the dated information and speculation that sometimes tends to persist in the public arena where Mars is concerned.”

Skin-tight Suits

The human body needs protection in low-pressure environments (e.g the vacuum of space or Mars’ low atmospheric pressure). Without protection, gasses in the body expand and liquids sublimate away, basically making the normal function of bodily systems impossible.

Gas partial pressures and operating pressures of suits and habitats are huge topics that I am not getting into here right now. What I want to mention is something that is a little surprising: skin itself is gas-tight and does not need as much protection as one would guess. All that is required is mechanical compression in order for it to maintain its normal shape and function.
