Can you walk on Mars (without) protection spacesuit? I think it is possible because it is only my thought. Is this true?

The research I've seen on this issue indicates that, even if you oxygenate your blood as well as possible (i.e., get yourself on the verge of hyperventilation), you can maintain consciousness in a vacuum or near-vacuum for anywhere from 15 to 30 seconds. Doing something strenuous that pulls the oxygen out of your blood faster (like running from one pressurized space to another) would tend to decrease your available time of consciousness.

So, in other words, the scene in 2001 *is* plausible, but sprinting on Mars for more than 20 or 30 feet probably isn't.

Someone should suggest this as a project for the Mythbusters, see if they can bust it or confirm it.
