The U.S. military has launched its secret space plane on another mission that's expected to last at least a couple of years
The U.S. military's X-37B space plane blasted off Thursday on another secretive mission that’s expected to last at least a couple of years.
Like previous missions, the reusable plane resembling a mini space shuttle carried classified experiments. There's no one on board.
The space plane took off aboard SpaceX’s Falcon Heavy rocket from NASA's Kennedy Space Center at night, more than two weeks late because of technical issues.
It marked the seventh flight of an X-37B, which has logged more than 10 years in orbit since its debut in 2010.
The last flight, the longest one yet, lasted 2 1/2 years before ending on a runway at Kennedy a year ago.
