White Knight Two Unveiled
xanthos writes "Sir Richard Branson was at the annual Experimental Aircraft Assoc Fly-in to show off EVE (previously known as White Knight Two), the launch vehicle for Virgin Galactic's commercial space operation. Test flights for the vehicle are slated for next year with the first paying passengers going up in 2011. What surprised me was the following from the article: 'So many people have signed up already, Whitehorn said, that the company has collected $40 million in deposits with orders to build five spaceships to meet the demand.' Will this mean that the $200k price tag may be dropping?"
Expensive, but I would do it if it were for a couple days in orbit...

Space tourism, yeah. But orbital flights?
Why SpaceShipOne Never Did, Never Will, And None Of Its Direct Descendants Ever Will, Orbit The Earth
Unless I'm mistaken, I'm pretty sure that the Virgin experience is completely suborbital. Basically it's $200K for a parabolic rocket ride. I don't understand the appeal. OK, so you left Earth's atmosphere for a couple of minutes.
Where's my 2001 space station?
A work that expires before its copyright never enters the public domain and thus enjoys eternal copyright protection.
So, instead of optimizing the vehicle to be just a launch system, they are creating additional revenue by adding in a passenger compartment. "Only $1,000 will get you a window seat where you can watch rich people fly into space!"

How is that bad? It's not like you're going to mess up the moon's ecosystem (it's dead) or that these projects would come to realization if marketing/product placement wasn't funding the initial effort...
What I'd like to see is even more commercialization of the moon so that the private sector can finally kick NASA's slow ass to mars ;)
Iirc it was 1964 when Star Trek came out. The science fiction stuff in it was pure fantasy; magic, impossible: cell phones, flat screen computers, doors that opened themselves, medical readouts in the hospitals, etc. It would be five more years before man walked on the moon; orbital flight was in its infancy.
Now it looks like another fantasy will come true - the price of space flight may become affordable to an average guy like me! This is simply amazing.
Free Martian Whores!
I just got back home from Oshkosh and saw the WK2 up close and personal there at Aeroshell Square. I didn't know beforehand that only the starboard side fuselage pod has any seats for crew. The left side fuselage has fake painted-on "windows" so that it looks like there are real windows from a distance, but apparently the left fuselage only contains equipment and possibly fuel tanks, there are no seats for any occupants on that side.
I took several photos of the center wing section where the spacecraft is supposed to attach. I saw no big heavy-duty attachment brackets there at all, but instead there were bundles of exposed wires only, and there were two cut-off loose wire ends just dangling out in the slipstream.
I did get one good photo of the WK2 in flight as it approached to land, but they did not do any repeated overflights for the crowd to see, I only saw one overflight, then it landed.
So if by "rubber" you mean "made from the sap of a rubber tree or a similar hydrocarbon synthetic designed primarily for flexibility and resilience", then no, it doesn't burn rubber. The fuel is designed primarily for high specific impulse, with the rubbery characteristics design in secondarily.
You are wrong, the engine burns rubber (at least synthetic rubber). From http://science.howstuffworks.com/spaceshipone5.htm
"To cut down on both cost and risk, SpaceShipOne is propelled by a mixture of hydroxy-terminated polybutadiene (tire rubber) and nitrous oxide (laughing gas). The rubber acts as the fuel and the laughing gas as the oxidizer."
Enigma
Yes. Truth be told, it doesn't matter what you use as the solid fuel in a hybrid rocket. You can use cardboard, salami, your mom, whatever. Some fuels are certainly better than others, but anything that burns with your oxidizer will work. They're probably using polyethylene or something similar (it's what we used in our college rocket club's hybrid rocket).
