From The Boeing Co. Streamed live on May 17, 2020: The autonomous X-37B spaceplane launched on its next mission for the U.S. Air Force and U.S. Space Force. A United Launch Alliance Atlas V rocket boosted #X37B into orbit. X-37B has some innovative NASA, U.S. Naval Research Laboratory and U.S. Air Force Academy research onboard this United States Space Force-7 mission. This test bed has spent 2,865 days on-orbit for the entire test vehicle program. Over a half-hour in length but well worth viewing.
