US Military’s X-37B Space Plane Settles Into Latest Mission

The U.S. Air Force’s mysterious X-37B space plane is quietly chalking up mileage in space more than two months after its latest launch into orbit.

The robotic X-37B space plane soared into orbit atop an Atlas 5 rocket from Florida’s Cape Canaveral Air Force Station on Dec. 11. The mini-shuttle’s mission is known as Orbital Test Vehicle-3 (OTV-3), since it is the third classified mission under the Air Force’s X-37B program.

How long OTV-3 will remain in Earth orbit is unknown. The hush-hush space plane mission is officially on Air Force space tracking books as USA-240.

"The mission is ongoing," Air Force Maj. Eric Badger, a spokesman for the X-37B program, told "As with previous missions, the actual duration will depend on test objectives, on-orbit vehicle performance and conditions at the landing facility."

There’s a possibility that OTV-3 may not land in Vandenberg. There have been discussions about bringing the space plane down at the space shuttle landing strip at NASA’s Kennedy Space Center, next door to Cape Canaveral, as a possible cost-cutting measure.

"The possibility of using the former shuttle infrastructure for future X-37B landing operations is still being investigated," Badger said.

Space test platform

The X-37B looks a bit like a miniature space shuttle. The vehicle 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.

Only two X-37B space planes have been constructed for the Air Force by Boeing Government Space Systems, officials say. Flights of the space plane are conducted under the auspices of the Air Force’s Rapid Capabilities Office.

According to an Air Force fact sheet, the Rapid Capabilities Office is working on the X-37B Orbital Test Vehicle “to demonstrate a reliable, reusable, unmanned space test platform for the United States Air Force.”

Mission control is handled by the 3rd Space Experimentation Squadron, 21st Space Wing, of the Air Force Space Command in Colorado Springs, Colo.
