X-37B returns from fourth orbital flight, makes first KSC landing.

Concluding a record-breaking stay in space, the U.S. Air Force’s X-37B spaceplane returned to Earth this morning. The vehicle spent more than 718 in orbit after launching atop an Atlas V rocket on May 20th, 2015. 

Although the X-37′s operations in orbit are classified, at least two of its payloads were confirmed to be an experimental electric propulsion engine and a materials exposure pallet.

The spaceplane performed a completely autonomous landing at Kennedy Space Center’s runway 15 shortly before 8am EDT, the same runway used by the Space Shuttle program. It marked the first time one of the Orbital Test Vehicle spaceplanes landed at Kennedy Space Center.

Following brief servicing on the runway, the vehicle will be towed to one of the former Orbiter Processing Facilities next to the Vehicle Assembly building. The Air Force has converted one of the old shuttle hangars for use by the OTV program to house their spaceplanes.
