Much lower indeed. It's now known that the surface pressure on Mars
is too low for any survivable pressure differential to suffice. A
respirator providing enough partial pressure of oxygen to keep you
from passing out would blow your lungs out. A full pressure suit
would be necessary, just like on the Moon.

Well, the "ace bandage" type suit would work, and, as John Campbell
pointed out, helps to solve some of the temperature regulation
problems regular pressure suits have, even (especially) in vacuum.

However, I don't know what pressure differential Heinlein had in mind.
Maybe it would have worked as he described, had Mars' atmosphere been
a little less hostile.

Trivia question: Where in the solar system, other than Earth, would
you *not* need a full pressure suit?

Dunno. One of the moons of Jupiter?

Aboard the International Space Station?
