[Update: The flight was a success.]
Virgin Galactic is preparing for the first powered flight of its spacecraft Unity on Thursday, CNBC has learned.
Richard Branson's space tourism venture is going to fire the engines of its vehicle during a flight at Mojave Air and Space Port, a person familiar with the situation told CNBC. (The news was first seen by the blog Parabolic Arc.)
Virgin Galactic has not tested a powered flight — as opposed to a glide — of one of its spaceships since the fatal crash of Spaceship Enterprise on Oct. 31, 2014.
After extensive testing and glide tests, Virgin Galactic's CEO George Whitesides said last year the company was "ready to go into powered flight." With engine testing complete, Virgin Galactic completed the seventh glide test of Unity at Mojave in January.
