Spacex had a test firing of the first stage of F9-R (Falcon 9 reusable)--advanced prototype for the world's first reusable rocket. The test took place at SpaceX's rocket development facility in McGregor, TX, lasting 112 seconds. Unlike airplanes, a rocket's thrust increases with altitude; F9-R generates just over a million pounds of thrust at sea level but gets up to 1.5 million pounds of thrust in the vacuum of space.
