Wikipedia lists the atmospheric pressure of Mars to be about 600 pascals, or just 0.6% of Earth's atmosphere. I'm wondering, can anyone shed any light on what that means, in practical terms?
Specifically, I'm looking for what might happen if a habitat on the surface of Mars, pressurized for Human occupants, got a leak. Not huge, like opening a door, but something along the lines of a bullet hole in the wall or a small meteorite impact.
Would that kind of pressure difference lead to an explosive decompression, or just the equivalent of a strong wind blowing out the hole? If they were outfitted with oxygen face-masks like Everest climbers, would the occupants be able to survive for long, or is that pressure quickly lethal? There are so many images of depressurization in space, that I'm having a hard time visualizing an accurate picture of depressurization into the Martian atmosphere.
Thanks in advance for any insight you have! This is my first question here, but I've already fallen in love with this particular Stack site.
