USA Today has a summary of the state of play of the space tourism industry by Bill McGee:

The MIT Technology Review blog Delta-V covers an interview with Burt Rutan:

• Burt Rutan Explains Why Space Tourism Matters

This is just plain dumb:-

"...propellants are responsible for about a third of the total cost of mature forms of travel, such as commercial airflight or automobile transportation, [Rutan] estimates that a sub-orbital ticket could one day cost as little as $475 per passenger, while a ticket to orbit could cost $12,000...While such orbital travel would be dramatically cheaper than the tens of millions charged today for private trips to the International Space Station, this would still dash romantic dreams of mass colonization of space by rocket."

Bullshit. At those prices, at least a billion people would have the income levels to be able to afford to go, and even at conservative estimates, tens of millions would actively want to go. I'd call that mass colonisation...
