I hope I see the first men or women (or both) on Mars in my lifetime although I suspect that they will be Chinese.
Then, I'll just wait to see if they get Heat Rayed or not...
In all seriousness though, I don't hold out much hope for space programs in the west for the next two or three decades. The current economic climate and the focus towards climate change means that anything outside of the planet takes a back seat. Look at the shuttle program for example.
Such a shame, but I guess it makes a bit of sense for humanity to try and solve its problems on one planet before it starts messing with another, lest we become a race of space locusts, wrecking one planet after another in an attempt to keep our civilisation alive.
