Mary asked Lois McMaster Bujold:

The planet Komarr is being terraformed. I dream of a future when we terraform Mars. Recently, it's occurred to me the Moon might be a better choice. Mars is so cold, and the Moon is just the right distance from the Sun. Since we found ice in a moon crater, we've got a start on the essential ingredient. Maybe we could snag a comet for additional water. Do you think humans might do this in the future?

Lois McMaster Bujold Insufficient gravity to hold a free atmosphere is a problem for both worlds, the moon more than Mars. Antarctica would be easier than either, but the seasonal affective disorders would be fierce. (Although Antarctica once had dinosaurs, so if global warming keeps going, who knows.) Colonies on either the moon or Mars would probably have to have enclosed arcologies like Komarr, for starters. The future is a long time; I wouldn't rule out anything, but I don't see it happening in the near future, for reasons of economics, biology, and physics.

Ta, L.
