MOJAVE, Calif. (Virgin Galactic PR) — Richard Branson joined Virgin Galactic and The Spaceship Company teams this morning, on the Mojave Air and Space Port flight line, to witness VSS Unity’s second successful, supersonic, rocket powered test flight.

“It was great to see our beautiful spaceship back in the air and to share the moment with the talented team who are taking us, step by step, to space” Branson said. “Seeing Unity soar upwards at supersonic speeds is inspiring and absolutely breathtaking. We are getting ever closer to realizing our goals. Congratulations to the whole team!”

The focus of today’s flight was to expand our understanding of the spaceship’s supersonic handling characteristics and control system’s performance with vehicle parameters that were closer to the ultimate commercial configuration. This involved shifting the vehicle’s center of gravity rearward via the addition of passenger seats and related equipment. The rocket motor burned for the planned 31 seconds and propelled Unity to a speed of Mach 1.9 and an altitude of 114,500 ft. As will be the case for future commercial flights, Unity’s unique re-entry feathering system was deployed for the initial descent before the final glide home to a smooth runway landing.

Once in commercial service, Virgin Galactic’s spaceships are designed to be turned around and flown at a higher frequency than has traditionally been the case for human spaceflight. The flight today brought that vision a little closer, coming less than two months after Unity’s first rocket powered flight. Great credit goes to the engineering and maintenance teams for working through the first flight’s data diligently and efficiently before preparing Unity again for flight.

Richard Branson was on the runway tarmac to greet this flight’s VSS Unity pilots Dave Mackay and Mark “Forger” Stucky. In addition to the pilots of VSS Unity, Branson recognized CJ Sturckow and Nicola Pecile, the pilots of the carrier aircraft, VMS Eve.

“Today we saw VSS Unity in her natural environment, flying fast under rocket power and with a nose pointing firmly towards the black sky of space” he said. “The pathway that Unity is forging is one that many thousands of us will take over time, and will help share a perspective that is crucial to solving some of humanity’s toughest challenges on planet Earth.”

The teams will now conduct flight data review for this flight and continue planning preparations for the next flight.

While in Mojave, Richard Branson also toured the facilities of The Spaceship Company (TSC), Virgin’s Galactic sister company. TSC is focused on manufacturing next generation aerospace vehicles, with a primary focus on new spaceships for Virgin Galactic’s future fleet. Branson viewed the next two spaceships on the TSC’s manufacturing line, as well as the production facilities for TSC’s spaceship rocket motors.

    So two more SpaceshipTwo are under construction for VG?

  • Congrats to the team. Fly safe and fly often!

    The VSS Unity will be retired after they finish flight testing and a very few operational flights. It is a prototype after all. So VG needs a replacement for paying customers along with at least one spare.

    So the cost keeps going up 😊

    With that unexpected slight yaw and pitch near the end of the burn, they might need to add some effective hydrazine jets/thrusters to the frame to cancel them out; and that may delay the next test flight a few more months. Better safe than sorry.

    It already has RCS.
