Video: Liftoff of Atlas 5 with X-37B on program’s fourth flight

Equipped with a robot arm, sample collector and return capsule, NASA’s asteroid-bound OSIRIS-REx probe emerged from its pristine factory and flew to the launch site in Florida on Friday.

A little more than a year after the Falcon Heavy rocket’s first test flight, SpaceX teams on Florida’s Space Coast are readying the world’s most powerful operational launcher for its second mission Thursday with a commercial communications satellite.

A United Launch Alliance Delta 4 rocket lifted off from Cape Canaveral at 8:26 p.m. EDT Friday (0026 GMT Saturday) with the U.S. Air Force’s tenth Wideband Global SATCOM satellite, extending the reach of the military’s highest-capacity satellite communications network.
