Of course I'm familiar with those programs. They're in their infancy stages right now, but as I said in my original post, they are the future of space exploration in this country.
Don't underestimate Burt Rutan. He's a dreamer, and he seems to be one of those gifted individuals who succeeds in almost everything he attempts. He's had a "vision to space" for a long time. If you watch the documentary "black sky: the race for space" he showed them some quick rendered designs on his computer and said "that Tier One will cover suborbital flights, Tier Two will cover orbital flights, and Tier Three will cover flights beyond Earth's orbit"
He is working on tier 1b right now, which is comerical and scientific operations based off of the designs developed for the tier 1 program.
Virgin Galatic, Richard Branson's space tourist company partnered with Rutan and Paul Allen's Mojave Aerospace Ventures, plans to begin commerical operations by 2011. It had 65,000 applicants for the first 100 tickets. It already has 200 paid in full applicants on it's books, and 95% have already passed the physical and health tests for flight. They each paid $200,000 per ticket. (quick math time that is $40 million dollars). Also, the first ship in the virgin line has been announced to have been named the VSS (Virgin Space Ship) Enterprise.
Also, take into mind the speed at which this is all running. Rutan started planning out his space designs and ideas in '96, prelim development on tier one started in 99, with full development starting in 01. The carry craft, White Knight, had a first flight in 02, SpaceShipOne had it's first test flight in 03, june 04 saw first powered test flight for SS1 and by oct 04 had won the X prize.
05 started the tier 1b operations, with the first SpaceShipTwo to be rolled out for testing in december of this year.
They go from paper to practice in 4-5 years. That's pretty good considering what they are doing.
