There has been renewed activity out here in Mojave on the SpaceShipTwo program as Scaled Composites gears up for a busy summer of flight testing. Scaled Composites conducted a taxi test on SpaceShipTwo on June 1 (see summary below), with the space plane spend three hours out on the runway. Three different pilots were at the controls as they tested new higher capacity brakes.

WhiteKnightTwo was also flying solo over Mojave on Sunday. That is believed to be the 81st flight of SpaceShipTwo’s carrier aircraft. Scaled has not posted a test flight summary on its website yet.

Officials have said that engineers have been installing engine components on the spacecraft. Glide flights of the heavier configuration are set for this summer. Powered flights using a smaller “starter” engine toward the end of this year.

SpaceShipTwo has not flown since Sept. 29 when the ship experienced a dangerous stall and fell precipitously. The pilots regained control of the vehicle by using the ship’s feathered re-entry system.

At a meeting on Tuesday of the East Kern Airport District Board of Directors, Mojave Air & Space Port CEO Stu Witt said he expected to see a new round of flight testing to begin shortly. Witt didn’t mention any specific companies among the many that are located here.
