Editor’s Note: SpaceShipTwo hasn’t been seen outside for months now. Its last powered flight was on Jan. 10. A week later, it made a glide flight. That was the last time it was seen in the skies over Mojave.
Sources tell Parabolic Arc that the suborbital ship has been modified with wing tanks. One tank will hold methane that will be used along with nitrous oxide to burn the plastic fuel. The other tank will include helium used to smooth out the end of the motor’s burn.
Company officials have said they expect to conduct a series of powered flights over the summer leading up to the first commercial flight from Spaceport America in New Mexico at the end of the year. That flight will carry Virgin Galactic Founder Richard Branson and his children.
