Sierra Nevada’s Dream Chaser to get its first test flight in the summer of 2012

Dream Chaser, Sierra Nevada’s space plane, is to get its first test flight this coming summer.

For the unmanned test flight, it will be carried into the skies by WhiteKnightTwo, the carrier aircraft for the commercial suborbital passenger ship SpaceShipTwo, backed by Virgin Galactic, a U.S. company owned by Richard Branson’s London-based Virgin Group.
