Photos: Falcon takes flight

SpaceX test-fired a Falcon 9 rocket for the second time Saturday after replacing a valve following an earlier static fire test Wednesday. The move has postponed the Falcon 9 rocket’s launch with the Amos 17 commercial communications satellite to no earlier than Tuesday.

A Falcon 9 rocket booster — under the power of a single Merlin 1D engine — descends toward a specially-outfitted ocean landing platform off Florida’s East Coast on Tuesday in a brief video clip released by SpaceX.

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.
