I think a manned expedition to Mars is unlikely in my lifetime. It still seems amazing that the first Moon landing was 1969, before I had started work! That is a long time ago.
For news of Mars, try http://marsnews.com/ .
Mars has fascinated us for a long time. There is little doubt it is a hostile place, but mankind will go there some day. I suspect this will be in the lifetime of my children.
The bigger question is, "is there other intelligent life in the universe?". CETI has been looking now for over 50 years without success. When (if?) we do detect other life out there, it will be a profound moment. If we are truly alone, we have to ask, "why?".
