Watch a 4K replay of the Atlas 5 launching for the National Reconnaissance Office

A Proton rocket launched from the Baikonur Cosmodrome in Kazakhstan with the EchoStar 21 communications satellite Thursday, the heaviest commercial payload ever flown aboard a Russian booster.

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.

SpaceX scrubbed the planned launch from the Kennedy Space Center of a Falcon 9 rocket Friday with the company’s next 57 Starlink Internet satellites and a pair of commercial Earth-imaging surveillance satellites. Officials did not immediately confirm a new target launch date.
