SpaceX sent up a classified payload for the National Reconnaissance Office from the Space Coast on Monday afternoon. A Falcon 9 rocket on the NROL-69 mission lifted off at 1:48 p.m. from Cape Canaveral Space Force Station’s Space Launch Complex 40.

SpaceX is about to launch its first private human spaceflight mission in nearly seven months. The mission will use a Falcon 9 rocket and Crew Dragon spacecraft to send four civilians into a polar orbit, in what will be a first for a human spaceflight mission.
