SpaceX hurled a secret cargo into space for the U.S. government’s spy satellite agency Saturday, the 30th rocket launch to fly into Earth orbit from pads on Florida’s Space Coast in 2020. The Falcon 9 flight broke an annual record for missions to reach orbit from the Florida spaceport that stood for 54 years.

The sixth and final satellite in the U.S. Space Force’s network of secure, jam-resistant AEHF communications satellites has been installed on top of a United Launch Alliance Atlas 5 rocket at Cape Canaveral for liftoff March 26.

Using a new, uprated main engine for the first time on a rocket of its kind, a United Launch Alliance Delta 4-Medium+ vehicle will soar into space Wednesday night carrying a $566 million Air Force communications satellite.
