Billionaire Richard Branson is moving Virgin Galacticâs space tourism operation from California to New Mexico.Branson said Virgin Galacticâs development and testing program of a winged passenger rocket has advanced enough to make the move to a custom-tailored hangar.The taxpayer-financed Spaceport America facility is near the town of Truth or Consequences.More than 100 employees will also make the move to the remote commercial launch and landing facility.In February, a new version of the company's SpaceShipTwo soared at three times the speed of sound to an altitude of nearly 56 miles in a test flight.
