  1. There are various reasons offered for planetary exploration but it makes little sense to me when people talk of establishing bases on other planets as a kind of life-boat for the human race should things get difficult here. As Ralph makes clear, if this is our concern we would be far better directing our efforts to ensuring that we don’t keep fouling our nest here. Reaching Mars with a crewed space-craft would be a spectacular achievement but I am sure it is not the answer to saving Homo sapiens.
