Why go to Mars via other than robots? There's neither life nor resources there to exploit. And what about food, shelter, water and heating for any Earth visitors/colonists? Other than full time government funded employment for Earth bound scientific types and corporations, humans going to Mars seems "a very hard road to travel".

If Mars was once a lush, green and blue planet like Earth, then there very well may be plenty of resources there to exploit. And of course, there's that whole extinction thing in a billion years or so (if not sooner).

I seem to recall that the longest lived hominin species was H. Ergaster/Erectus which was about 2 million years. Given the technologies and mental disposition of H. Sapiens, we don't have the luxury of such a time scale. H. Sapiens, or an evolving sub species, does need to leave Earth in about a billion years, preferably much sooner, (i.e. prior to the forecasted natural environmental changes). IMO, Mars just ain't the long term place to go, practice and learning notwithstanding.
