When I came home from a late night of work last night, I found a two hour program showing about the Mars Phoenix
mission. One of the
scientists said that the atmosphere on Mars was about 1% that of earth.
I had no idea the difference was so substantial.
Looking it up: Atmosphere:
Earth 101.325 kPa
Mars 0.636 kPa
Also, I had the impression that the experiments carried on the Phoenix probe specifically designed to judge human habitability were about what
resources might we not be required to bring with us. The Moon offered nothing to sustain human life-- so everything had to be brought.
Mars, is little better-- and the only reasonable hope, I think, was that we might find organic material suitable for nourishment. The Phoenix did
So, it appears that we would require pressure suits, oxygen, food and water, heat and shelter-- no different then the moon. Mars probably does not
even have WiFi.
We can create 97% oxygen easily by simply filtering out the Nitrogen (78%)-- those little units persons with Lung disease carry over the shoulders and
which run on battery do that.
Oxygen accounts for only 0.17% While we could filter out Carbon Dioxide (98%), Nitrogen (2.7%), and Argon (1.6%) to get to mostly oxygen-- but even
that would be at a pressure of only 6/1000ths.-- so pressure suits would be required whether the human body could function at such low pressure or
From what I have read our individual cells would be able to contain the water in them if exposed to such low pressure-- so the exploding body and
boiling blood thing seems to be the stuff of movies-- but not reality.
However, the saliva on your tongue would boil! Cool. Also even at 1 psi (normal is 14.7 psi), a test subject passed out from lack of ability to get
oxygen to the blood.
