Dumb question probably, but here goes:
Given the latest NASA news about water on Mars, as in, “flowing water on today’s Mars,” I am still trying to figure out how that would work.
If water boils at 79ºF when the atmospheric pressure is lowered to 0.5psi, what would it boil at given Mars’ atmospheric pressure of 0.087psi?
How could Mars, which barely has an atmosphere, support liquid water? Why would not the water basically evaporate quickly if not boil off almost instantly?
