Virgin Galactic completes first rocket-powered, supersonic flight of its new spacecraft, Unity

  • Virgin Galactic launches its rocket-powered Unity spacecraft.
  • Unity's test flight reached supersonic speeds of Mach 1.87.
  • This is the first powered flight test of a Virgin Galactic spacecraft since the fatal crash of Spaceship Enterprise on Oct. 31, 2014.

Virgin Galactic completed its first powered flight in nearly four years on Thursday when Richard Branson's space company launched its Unity spacecraft by rocket power, reaching supersonic speeds before safely landing.

Unity took off from the Mojave Air and Space Port, lifted by the jet-powered mothership Eve. The carrier aircraft lifted Unity to an altitude of 46,500 feet above the desert. Eve released Unity from under its wing and, with a two-member crew of Mark Stucky and Dave Mackay, Unity's rocket motor roared to life. The rocket screamed into a steep climb as the engine burned for 30 seconds, pushing Unity past the speed of sound to Mach 1.87.

"On rocket shutdown, Unity continued an upwards coast to an apogee of 84,271 feet before readying for the downhill return," Virgin Galactic CEO George Whitesides said in a statement.

The Unity craft the turned and glided back to land at Mojave, with Eve touching down soon after. It was the fifth powered test flight of the SpaceShipTwo design, and the first since the fatal crash of Spaceship Enterprise on Oct. 31, 2014.

The spacecraft underwent extensive engine testing and seven glide tests before Virgin Galactic said it was ready for a powered test flight — a crucial milestone before the company begins sending tourists to the edge of the atmosphere.

The original SpaceShipTwo craft was built by experimental aircraft developer Scaled Composites. In 2016, Virgin Galactic unveiled the version of the SpaceShipTwo design on which Unity is based, built by The Spaceship Company. A subsidiary of Virgin Group, The Spaceship Company made alterations to the design, intending to avoid a repeat of the 2014 accident. The company is also building two more spaceships, intended to become part of the Virgin fleet for taking people to the edge of space.

Future passengers who are willing to pay $250,000 will be taken up with help from the spacecraft's mothership. When it reaches a certain altitude, the Virgin Galactic craft will launch into space around 68 miles above the Earth's surface, before re-entering the planet's atmosphere.

Branson's space companies recently got a boost from the Kingdom of Saudi Arabia, which announced intentions to invest $1 billion in Virgin Galactic, The Spaceship Company and Virgin Orbit. At the time of the announcement, Branson said Virgin Galactic was near its intended goal.

"We are now just months away from Virgin Galactic sending people into space and Virgin Orbit placing satellites around the Earth," Branson said.
