A SpaceX Falcon 9 rocket lifted off Thursday from NASA’s Kennedy Space Center in Florida with the U.S. Air Force’s X-37B mini-shuttle, an unpiloted orbiting military laboratory. Liftoff occurred at 10 a.m. EDT (1400 GMT), and the Falcon 9’s first stage booster successfully landed at Cape Canaveral a few minutes later.

The change will allow the U.S. Space Force to expedite the process of building out its GPS constellation in medium Earth orbit. The launch date for the next satellite, GPS III Space Vehicle 09, could be within weeks.

Taking delivery of the Atlas 5 rocket that will boost an advanced weather observatory into space next month, United Launch Alliance and the Air Force are back at work following disruptions from Hurricane Matthew.
