Not drag from friction, but gravity is what i meant. The same effect that causes the moon to face earth.

Would the dark matter provide drag? I wonder what the movements of dark matter would be in galaxies like that. I assume for the Milky Way it just rotates in line with the movement of stars (or more accurately, the stars move in line with the dark matter)

It only needed one person to do this, though.

Mars atmosphere is thin, almost a vacuum being about 1% of earth. Something those who are big on Mars colonies get upset if you remind them. So it may not make much difference.
A telescope on the moon would be easier than putting on Mars but i guess if you were going to do it on Mars than Olympic Mons would be a good place. We put them on volcanoes on Earth frequently so there is lots of precedence.
The moon has a lower rotation speed so probably has other benefits too.

Isn’t it basically flat? 25km over the area of France should be so gentle a slope as to be unnoticeable

600 billion litres. By the time we use that we will be able to reposition a comet for resupply.
