The U.S. Air Force's robotic X-37B space plane came back to Earth on June 16 after 15 months in orbit on a mystery mission, and its much-anticipated landing was caught on video.
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 video of the event.
Designed to be launched like a satellite and land like an airplane, the second X-37B Orbital Test Vehicle, built by Boeing for the United States Air Force's Rapid Capabilities Office, is an affordable, reusable space vehicle.
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.
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 technologies for future satellites.
