The Boeing-built X-37B Orbital Test Vehicle launched on August 21 for its eighth mission, marking another milestone in the vehicle's ongoing role as a platform for advanced experimentation and testing in orbit. The launch took place at 23:50 ET from Kennedy Space Center on Merritt Island, Florida, using a SpaceX Falcon 9 rocket. This mission comes less than six months after the completion of the seventh mission, which ended with a landing at Vandenberg Space Force Base in California.
The X-37B is an uncrewed, autonomous spaceplane designed to return to Earth after completing experiments in orbit. According to Boeing, "the vehicle is healthy on orbit and proceeding with standard checkout." The latest mission includes a Boeing integrated service module intended to increase payload capacity for experimentation activities.
During this eighth flight, the spaceplane is carrying several technology demonstrations from government partners. These include laser communications and a quantum inertial sensor aimed at supporting navigation when GPS signals are unavailable. On its previous mission, the X-37B executed an aerobraking maneuver—a first for this type of vehicle—to change orbits while conserving propellant.
