A permanent base on Mars would have a number of advantages beyond being a bonanza for planetary science and geology. If as some evidence suggests exotic micro-organisms have arisen independently of terrestrial life studying them could revolutionise biology medicine and biotechnology.

The sea is everything. It covers seven tenths of the terrestrial globe. Its breath is pure and healthy. It is an immense desert where man is never lonely for he feels life stirring on all sides.

There is only one way to achieve happiness on this terrestrial ball and that is to have either a clear conscience or none at all.

It is dangerous for mortal beauty or terrestrial virtue to be examined by too strong a light. The torch of Truth shows much that we cannot and all that we would not see.
