SpaceX launches Air Force’s super-secret minishuttle

It’s the fifth flight for one of these crewless mini shuttles, known as the X-37B Orbital Test Vehicle. (SpaceX via AP) SpaceX launched the Air Force’s super-secret space shuttle on Thursday, a technology tester capable of spending years in orbit. The unmanned Falcon rocket blasted off from Florida’s Kennedy Space Center, as schools and businesses boarded up for Hurricane Irma.

The two Air Force space planes have already logged a combined 5 ½ years in orbit. But officials won’t say what the spacecraft are doing up there. The last mission lasted almost two years and ended with a May touchdown at the runway formerly used by NASA’s space shuttles. The first one launched in 2010.
As has become customary, SpaceX landed its leftover booster back at Cape Canaveral for eventual reuse.
This was the first time SpaceX has provided a lift for the experimental minishuttle. The previous missions relied on United Launch Alliance’s Atlas V rockets. Air Force officials said they want to use a variety of rockets for the X-37B program, to launch quickly if warranted.
The Boeing-built minishuttle is 29 feet long, with a 14-foot wingspan. By comparison, NASA’s retired space shuttles were 122 feet long, with a 78-foot wingspan.

(U.S. Air Force via AP) SpaceX stopped providing details about the X-37B’s climb to orbit, a few minutes after liftoff at the Air Force’s request. The booster’s return to SpaceX’s landing zone at Cape Canaveral Air Force Station, however, was broadcast live.
”The Falcon has safely landed,” a SpaceX launch controller announced. Cheers erupted at SpaceX headquarters in Hawthorne, California.
It was SpaceX’s 16th successful return of a first-stage booster. Booster rockets are normally discarded at sea.
