Have you heard of Anousheh Ansari? She's a space tourist, the fourth one in history and the first woman, and she has a blog that gets updated several times a day. (She can't blog live because of Internet connection outages during orbit; instead, she sends down emails that her friends post on the web.)
Only the very wealthy can afford space travel right now, but what will happen in 15 or 20 years? Will the merely well-off be able to go up? Will there be private space stations catering to the ultimate in tourism? And what would happen if many people experienced a view of Earth from space? That could be one of the drivers of Homo sapiens' maturation.
On a related note, Thomas P.M. Barnett notes a New York Times article about Mike Griffin, the director of NASA, visiting China. I hope we do start to cooperate in space.
