CAPE CANAVERAL — Hobbyists who keep track of the skies with remarkable precision have found the U.S. Air Force’s mini space shuttle in its no-longer-secret orbit around the Earth.
The X-37B craft, making the program’s fourth mission into space, was launched May 20 from Cape Canaveral atop a United Launch Alliance Atlas 5 rocket.
The ascent entered a news blackout about five minutes after liftoff, as the Centaur upper stage began its burn to put the spaceplane into low-Earth orbit.
It wasn’t until later that officials confirmed the launch had gone smoothly for the Orbital Test Vehicle mission No. 4. It is believed the Centaur deployed X-37B about 19 minutes into flight.

The robotic X-37B space plane launched atop a United Launch Alliance Atlas V rocket at 11:05 a.m. EDT (1505 GMT) from Florida's Cape Canaveral Air Force Station.
The Air Force owns two X-37B spacecraft, both of which were built by Boeing's Phantom Works division. Each space plane is just 29 feet long by 9.5 feet tall (8.8 by 2.9 meters), with a wingspan of 15 feet (4.6 m) and a payload bay the size of a pickup-truck bed. To put those dimensions into perspective, both X-37Bs could fit inside the payload bay of NASA's now-retired space shuttle orbiter.
The X-37B launches vertically and lands horizontally, on a runway, as the space shuttle did.
