even a planet wide catastrophe would leave earth more hospitable than mars. there is just no sane argument for living on mars. a nice fantasy? definitely- I love scifi but from a rational point of view its just not desirable.
- danieltillett 11y agoImagine earth is struck by a 10km asteroid. This may well kill everyone on the planet. Having a self-supporting colony on mars or the moon would avoid humanities extinction.
- Symmetry 11y agoEven after a dinosaur killer class 10km asteroid impact Earth would be way easier to live on than Mars. Despite the particulates in the air the surface would be warmer, the air would be breathable, and even with the reduction from dust the surface sunlight would be comparable.
- verinus 11y agoexactly my thoughts. i think the effort and money would be better invested in earth itself: affordable renewable enery sources pose one of the greatest challenges of our time. in my opinion all money poured into mars missions is a waste and should be used to make progress in other fields. as for asteroids: a) the mars is as likely to be struck by an asteroid as earth and b) its imho a better idea to build defenses to prevent that.
- danieltillett 11y agoIt is certainly a good idea to build defences against the Earth being struck by an asteroid, but I should mention that the Earth because it is considerably large is much more likely to be hit by an asteroid than Mars.
