Re: Responded to below, but here's more...
It is absolutely ridiculous to state that a suit could not be developed to support humans on Mars' surface. Obviously, Uncle Eddie has yet again let his agenda get in the way of facts. No space suit development of substantial effort has occurred since the 60s. In the late 60s experimental skinsuits were tested in vacuum chambers with humans. This was abandoned by NASA. Hard to believe that 21st century materials science and biofeedback sensors could not produce a superior lightweight suit for 10 millibars pressure. On Mars, heat elimination is not the problem that it presents on the moon. Like on the moon, dust is the pesky issue.
