Reply to comment by StrangeTangerine1525 in The Europa Clipper mission may be as exciting as a manned mars mission and it’s only two years away by Wide-Escape-5618

The problem is mars has already lost a lot of its atmosphere, it’s a big job to replace it and we already know it’s a leaky boat. Plus even if it did have an atmosphere everything would be irradiated. We can certainly move about on it’s surface but it’s never going to be like earth.

It was a leaky boat three billion years ago when the Sun had a much higher ionizing radiation output and solar flare rate, also why would it’s surface be irradiated if it has a 1 bar atmosphere? With current evidence Mars in theory should have more than a bar of CO2 locked up in its crust, and if we want to make the air breathable we can just import it from some place else.
