Re: Thanks, this does tell
Read one of my many articles about Mars or my book. Don't be lazy.
The pressures needed to keep CO2 in iiquid form are on the order of 80 atmospheres (or psi, i can't recall which) while Mars has 1/100 of one atmosphere.....it's possible such pressures exist deep within the surface and that CO2 is in liquid form somewhere down below, but the odds
of it geysering to the surface and running down gullies before sublimating
into vapor are in my opinion, about the same as me hopping the next New York subway to Vallis Marineris. How's that for articulation?
Now lt's hear you articulate on something other than sending colonies to Mars.
