don't be stupid. the olympic games have cost 3 times what the mars rover curiosity has cost and the return from the mars rover will be far far more lasting and enduring than any 2 week sporting holiday. I guess you approve of the 1.2 trillion dollar military budget half of which is used to provide employment for people who normally would be to stupid to get a job.
While people are fixated on what Lady Gaga and NASA are spending the military is quietly building their own rockets and has just landed the X37 unmanned orbital vehicle which has been circling the earth for over a year. It's the old magician's trick of using blue smoke and mirrors and lots of hand waving to distract the audience from what is really happening.
No, I think the military is determined to own orbital space and eventually expand outward from there. Both the military and private industry have been showing particular interest in asteroids lately. A single asteroid dragged into near earth orbit could provide invaluable resources and the list of imports on the list of "necessary for the national defense" keep growing.
