Re: Mars and Beyond
Yes, Mars does have an atmosphere of about 3 to 10 millibars and our is 1000 millibars. We have aircraft which fly at 90,000 feet (about 10 millibars). In Mars atmosphere about .01 percent is water. Doesn't sound like much, but it would make a lake about the size of largish lake here in Washington State.
Apollo Astronauts didn't die "immediately" of radiation exposer. I think you're exaggerating the problem a bit.
