User blog comment:Eastward Expansion/What do you think the Future will bring? (Book Review part 1)/@comment-257949-20100730150311

I think that space exploration will be headed by China and India, with NASA and the ESA growing less and less important. China and India will take us back to the Moon and possibly further with international backing. I doubt any trip to Mars will happen in the near future, but I'm pretty confident that we will have reached there before 2100, though most likely after 2045.

However, it will be the new space companies that will grow the most. In maybe three decades at most we will see a viable space-tourism industry, though still limited to the very rich.
