It probably is easier to survive long term on Mars than Earth because Mars has a very thin atmosphere. Earth could pull a Venus. Earth life on Mars requires underground small sealed compartments with radiation shielding which is a more survivable architecture than one big shared ecosystem.
- coptun 5y agoYour definition of "long term" is stretching it a bit. If Earth "pulls a venus" it will be 100+ million years from now due to the expansion of the sun.
- DangitBobby 5y agoI thought the surface Venus was incredibly hot and uninhabitable mainly to the thick greenhouse gases in it's atmosphere. Why does the sun need to expand for that to happen on Earth?
