Good news for people who want to have a space wedding or drink some Martian mineral water: Virgin Galactic, the space tourism venture co-sponsored by British mogul Sir Richard Branson and aerospace designer Burt Rutan will unveil their ship White Knight Two tomorrow. Over two hundred people have already plunked down $200,000 to take Virgin Galactic’s rockets to space when the program begins sometime after late 2009. White Knight Two will carry the rockets 50,000 feet in the air before releasing them. After disengaging from White Knight Two, the Virgin Galactic spaceships will fly to a maximum height of 363,033 feet. Though White Knight Two will be ready to present to the public tomorrow, the spaceships are still being kept under wraps and Virgin says they are only about 70% completed.
