Yup... Chunky style!
(I don't trust air I can't see.)
"Total Recall" was a Pretty Good Effort at an Old, Very Good, Science Fiction Story by one of the Great "Science Fiction" Authors.
NO ONE has EVER "Pretended" that the "Story" was IN ANY WAY "Related to 'Reality.'"
The Author--Philip K. Dick--wrote the story to comment about "Human Nature;" NOT as a "Treatise on Human Technology!!"

The trusty shortwave was able to pick up Radio Canada this morning. Caught part of a discussion about polluting "other worlds"
and "humans" aren't going to go underground on Mars because there might be contaminatable "life" in them thar holes.
John F'ing Kerry 'em. The envirowackos here, I mean.
But first let us tackle Mars.
And Titan may be more inhabitable than Mars! Not in the sense that you could walk on the surface. More in that the atmospheric pressures suitable contained could be workable. Titan also holds VAST VAST VAST VAST (did I say Vast yet?) quantities of Hydrogen and Helium 3. Think of Titan as the big gas station of the solar system.

Man did I bork my reply.

Dick also wrote the story that became the movie "Minority Report", a good story of the human condition and governmental abuse. I believe he wrote some others that became movies but can't remember for sure. Good writer.
Well why not? Lots of males of certain sexual persuasions happily survive in 'Uranus.'
What is the boiling point of water at 7mb?
I would think that even breathing pure oxygen it would be necessary to have the air one's breathing be at a pressure over 7mb, but how much above? At 200mb a pure oxygen atmosphere would yield a partial pressure of oxygen comparable to that of earth sea level. Lower levels would require a person to acclimate by increasing lung capacity, but I would think that doable to some extent.
The question then becomes whether it would be practical to have a survival apparatus which was lighter and more convenient than a full-fledged space suit. I don't know what the practical limits are; a 7mb Martian atmosphere seems like it would be a bit on the low side to offer much assistance, but it might offer a little.
Actually, that reminds me of a thought I had a few years ago: one key to being able to set up an effective form of habitation may be having an atmospheric pressure which is above the vapor pressure of some convenient liquid. If the Martian atmosphere were above the vapor pressure of some liquid which could be locally synthesized, then one could dig or find a crater, fill it with liquid, and put a habitation at the bottom. Ballast would be needed to keep the habitation from floating, but differential pressures could be kept comparatively modest.
