  1. Question

    Do you think human beings will ever be able to live on other planets?

    Yes. Remember that humans have already lived on the Moon, but only for a few days. NASA's current plans for human exploration of the Moon and Mars suggest that there could be permanently occupied outposts on both Moon and Mars by the middle of this century. David Morrison
