The Falcon lifted on Sunday from Cape Canaveral Air Force Station. As the first-stage of the Falcon returned to Earth for an upright landing, the upper stage lofted the mysterious Zuma, presumed to be a spy satellite or military communications satellite, into an undisclosed orbit.

SpaceX and the Pentagon have not provided any comment on Zuma mission.
