> Even Mercury is better than Mars

...how? It's further. It has no atmosphere. There is no water or carbon.

How is Mercury further? On average it's the closest planet to earth.

Mars's atmosphere is pretty useless for humans.

Δv, the only metric that matters. Mercury is at 5.5 km/s from LEO, vs 3.6 km/s from LEO for Mars.

Oxygen, carbon, nitrogen and hydrogen make up 95+ percent of a human by mass. Mars has all four, the first three in the atmosphere.

To be fair to JumpCrisscross, he never claimed Mercury was further away. It's just "further".
