SS2 expands test envelope in second supersonic flight

Richard Branson's Virgin Group and Abu Dhabi's aabar Investments PJS, have successfully completed the second rocket-powered, supersonic flight of its passenger carrying reusable space vehicle, SpaceShipTwo (SS2).

In addition to achieving the highest altitude and greatest speed to date, the test flight demonstrated the vehicle’s full technical mission profile in a single flight for the first time, including a high altitude deployment of the unique wing “feathering” re-entry mechanism. All of the test objectives were successfully completed.

On 5th September, at approximately 8 a.m. (local time) from the Mojave Air and Space Port, the company’s WhiteKnightTwo (WK2) carrier aircraft took off carrying SS2 to an altitude of 46,000 feet.

Virgin Galactic Chief Pilot Dave Mackay was at the WK2 controls, assisted by Scaled Composites (Scaled) co-pilot Mike Alsbury and The Spaceship Company Flight Test Engineer Scott Glaser. Upon release from WK2, SS2 pilots Mark Stucky and Clint Nichols, both of Scaled, ignited the rocket motor for the planned 20-second burn propelling the spaceship to 69,000 feet. During this time, SS2 achieved a maximum speed of Mach 1.43. SS2 landed in Mojave at 9.25 a.m. local time completing the flight test with the pilots reporting a flawless flight.

Chairman of aabar Investments PJS, H.E. Khadem Al Qubaisi, said: “This flight milestone represents a key step forward for the Virgin Galactic team. The successful completion of all major aspects of the flight mission demonstrates that we are very close to achieving one of Galactic’s key goals: commercialising access to space for the broader public. I would like to congratulate the whole team on their continued success.”

Virgin Galactic Founder Sir Richard Branson said: “We couldn’t be more delighted to have another major supersonic milestone under our belts as we move toward a 2014 start of commercial service.

“It was particularly thrilling to see for the first time today the whole elegant system in action during a single flight, including the remarkable feathering re-entry system. It was this safety feature more than anything else that originally persuaded us that the overall design of the system was uniquely fit for purpose. Everything we have seen today just confirms that view. Congratulations to all involved!”

“We expanded the SpaceShipTwo rocket-powered flight test envelope with a longer burn duration and robust testing of the feather mechanism, supersonic aerodynamics and wing lift structure,” said Virgin Galactic CEO George Whitesides. “Each powered flight of SpaceShipTwo yields cumulative progress that builds the foundation for safe and exciting commercial space flights.”
