This should give us a graduated pressure shell frozenin foam form. Using a graduated pressure shell in this fashion should offer many advantages. The chance of catastrophic decompression should be much lower. The great pressure difference between normal atmospheric pressure and hard vacuum will be distributed over many layers of reinforced foam, and supported by the ice layers and rock below that. Foamed Gradient ...
