Personally, I would rather live near Mercury's north pole than anywhere on Mars mainly because:
- The permanently shadowed craters harbor abundant water ice and other frozen volatile materials
- Mercury receives 15 times as much solar energy on average as Mars does.
- Mercury's crust has carbon-bearing material, combined with the solar energy suitable to extract metals from their minerals and oxides, i.e. to perform pyrometallurgy with concentrated solar power.
- At 80⁰ N latitude the subsurface temperature below 1 m depth is a constant 0⁰ C, independent of the diurnal surface temperature variation. (Values derived from this article)
But it's been stated many times that it's so hard to get there because of the proximity of the Sun.
From the BBC news article "What is Elon Musk's Starship?":
"You could conceivably have five or six people per cabin, if you really wanted to crowd people in. But I think mostly we would expect to see two or three people per cabin, and so nominally about 100 people per flight to Mars," Musk said. The payload bay would also host common areas, storage space, a galley and a shelter where people could gather to shield from solar storms, where the Sun belches out harmful charged particles into space.
I really would like to know how many people could be transported to the surface of Mercury's north pole with such a Starship, taking into account the longer trajectory to the aphelion of Mercury's orbit than that to an orbit around Mars.
Please with the necessary calculations to be able to control the assertions in your answer !
