SpaceX’s hulking Falcon Heavy rocket returned to the skies Thursday evening, and this time it launched a mysterious spacecraft for the US military that will carry out cutting-edge research.
The rocket lifted off from NASA’s Kennedy Space Center in Florida at 8:07 p.m. ET, carrying the military’s X-37B space plane — which is uncrewed and operates autonomously — to unprecedented altitudes. The launch streamed live on SpaceX’s website. The side boosters returned to Earth and safely touched down.
It is not clear, however, exactly where the space plane is going.
The X-37B’s activities in space have long been the subject of fascination and speculation in the space community as amateur enthusiasts race to track its whereabouts and share theories about its activities.
