The US military’s experimental X-37B space plane has landed at NASA’s Kennedy Space Center in Florida.
It has returned to Earth after completing a classified mission that lasted nearly two years, according to the US Air Force.
Who was on board?
The unmanned X-37B touched down at 0747 am local time on a runway formerly used for landings of the now-mothballed space shuttles.
When did it take off?
The Boeing-built space plane blasted off in May 2015 from nearby Cape Canaveral Air Force Station aboard an Atlas 5 rocket built by United Launch Alliance.
ULA is a partnership between Lockheed Martin Corp and Boeing.
What did it do in space?
The X-37B conducted unspecified experiments for more than 700 days while in orbit.
It was the fourth and lengthiest mission so far for the secretive program, which is managed by the Air Force Rapid Capabilities Office.
Are there plans for more missions?
The Air force intends to launch the fifth X-37B mission from Cape Canaveral later this year.
