The plane is known as the X-37B, and it launched atop a Falcon Heavy from Kennedy Space Center on Dec. 28, 2023. The uncrewed Boeing vehicle remains in orbit, according to the Space Force, preforming various maneuvers and experiments. But little else about the plane's activities have been revealed so Friday's release of the photo by the Space Force caused a stir. The photo shows Earth, and the Space Force said it was taken sometime last year from an onboard camera. The onboard cameras, according to the Space Force, are used to monitor the status of the space plane. This flight is the plane's seventh mission. It first flew in April of 2010. Across these various missions, this mysterious orbiting plane has racked up more than 4000 days in orbit. FLORIDA TODAY previously reported the last flight of the X-37B lasted 908 days. A bit of information on the vehicle's activities was also given on Friday. "The X-37B executed a series of first-of-kind maneuvers, called aerobraking, to safely change its orbit using minimal fuel," the post read.
