The X-37B spacecraft touched down at California's Vandenberg Air Force Base at 5:48 a.m. local time Saturday (8:48 a.m. EDT; 1248 GMT). Several hours later, Vandenberg officials released a short [URL="http://www.msnbc.msn.com/id/47849012/ns/technology_and_science-space/#"]
The first part of the 80-second video was apparently shot in infrared light. It shows the X-37B space plane cruising in for an automated landing, its belly and nose glowing a bright orange-yellow, presumably from the heat generated during re-entry to Earth's atmosphere.
The video switches over to visible wavelengths about 35 seconds in, after the space plane has touched down, and shuts off shortly after the X-37B rolls to a stop on the runway. [Photos: Air Force's 2nd Secret X-37B Mission]
The X-37B, also known as Orbital Test Vehicle-2 (OTV-2), launched on March 5, 2011, from Florida's Cape Canaveral Air Force Station. Its flight was the second-ever mission for the X-37B[URL="http://www.msnbc.msn.com/id/47849012/ns/technology_and_science-space/#"]
OTV-1 blasted off in April 2010 and stayed aloft for 225 days, well below the supposed 270-day orbital limit for the space plane. But OTV-2 smashed that limit, zipping around our planet for 469 days before finally coming down today.
Just what OTV-2 was doing up there for so long remains a mystery. Details of the vehicle's mission are classified, as are its payloads. The secrecy has spurred speculation notably from China that the X-37B may be a space weapon of some sort, but Air Force officials have long insisted that the spacecraft is simply testing out [URL="http://www.msnbc.msn.com/id/47849012/ns/technology_and_science-space/#"]
The X-37B looks like NASA's recently retired space shuttle, but it's far smaller. The X-37B is 29 feet (8.8 meters) long and 15 feet (4.5 m) wide, with a payload bay about the size of a pickup truck bed. For comparison, two X-37B vehicles could fit inside the payload bay of a space shuttle.
The 11,000-pound (5,000-kilogram) space plane's orbital longevity is enabled by its solar array, which generates power after deploying from the payload bay.
The X-37B is built by Boeing, though NASA originally used the vehicle as an experimental test bed until [URL="http://www.msnbc.msn.com/id/47849012/ns/technology_and_science-space/#"]
