“This first-of-a kind maneuver from the X-37B is an incredibly important milestone for the United States Space Force as we seek to expand our aptitude and ability to perform in this challenging domain,” B. Chance Saltzman, chief of space operations of the U.S. Space Force, said in the statement.

The news is a rare offering of information from the Space Force and Boeing, which are incredibly secretive about the X-37B’s activities. The craft launched on its first mission in 2010, but few details have been revealed about its highly classified purpose in space.
