The classified U.S. Air Force X-37B space plane program is now flying its Orbital Test Vehicle (OTV-5) mission. Skywatchers are reporting the craft recently made an orbital altitude change.
OTV-5’s space jaunt began on September 7, 2017. To date, the orbiting craft has chalked up some 225 days of flight.
