..in fact it's cold as hell...
Rocket Man, Elton John
Sir Elton wrote that in 1972. The US Government would like to make Man on Mars a reality by 2030. That and a number of other factoids and other space opportunities show up in Business 2.0's cover story on The Entrepreneurs Guide to the Galaxy. Tech billionaires such as Paul Allen and Jeff Bezos are funding some of the space startups.
For a picture gallery of likely opportunities from Asteroid Mining to Space Hotels to the Moon again (as a prelude to the Mars manned mission) page down in this article.
Maybe by 2050 we will be as cynical as Elton's Rocket Man, but for the next couple of decades space looks pretty exciting.
