Default Skin tight space suits ?

Forgetting for a second temperature and radiation.

If astronauts wore some airtight lycra suit that was right up against
the skin (so no air between skin and suit), would the skin be protected
from vacuum? Would tension of suit against skin be enough to make skin
think it wasn't in vacuum?


blackout reduction flight-suit panels can stop/reduce the motion of blood to the abdomen. But negative gee-force versions around the head won't work because there are chest ribs and a head skull. In theory, suit con-formal force could work. But there must be careful air equilibrium control. It basically demands a resiliency around the chest lungs to function in opposition to lung air inflation. The cost would be a careful custom suit of very high cost.

Getting in and out of this suit would require special zipper work.

In an alternative is the "cheap" several size suits. So put the development money one way of another.

In my mind the basic design issue is joint resiliency in one size fits several human sizes. As an avenue of engineering I like the concept of memory metal joint supports. Systems of these could be placed in opposition to cause/allow computer controlled electric joints. I forget the exact terms for such exoskeleton technology.

Changing a computer drawing pad technology for pressure sensing is allowed. These pads are very sensitive to pad pen pressure. An interior, to the suit, suit could accurately instigate joint motion.
