Richard Branson's space tourism company Virgin Galactic has successfully completed its second fully-crewed flight to the final frontier.
The rocket plane "Unity" was released from a carrier aircraft this morning high above the New Mexico desert. It ignited its engine and shot up to 54.2 miles above the planet, according to the company. That's high enough to get a great view and experience a few minutes of weightlessness, but not enough to stay in space, circling the Earth.
