IMHO, it's only a matter of time, money and technology before a manned mission to Mars happens.
After all, we did it on the moon.
Humans are the greatest "robots" ever created... with extra equipment of course while exploring.
What concerns me is whether or not they can, or want to, return to Earth. Surely a lauch facility similar to NASA would have to be constructed on Mars for a return trip. That, in itself, is a massive undertaking.
I've heard loose talk about a "non-return" manned mission. That is, establishing a human colony(including proper male/female breeding) that will likely never see earth again(excepting grandchildren of course)
I could understand that with a voyage to the Stars, but surely Mars is near enough for it not to have to be a one-way trip? I'd have thought the most sensible way would be for a mother ship to remain in orbit and for a lander to go down, and while that would still leave questions to be addressed about where to find enough fuel for the return trip, at least you'd need a lot less fuel than you would if you were taking off directly from the surface.
