SpaceX test fires a Falcon 9 rocket in readiness for its planned 8 September 2018 launch carrying the Telstar 18 VANTAGE communications satellite.

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.

The two structural elements of Orbital ATK’s OA-7 Cygnus space freighter were delivered to Kennedy Space Center for final assembly, the packing of cargo and launch to the International Space Station.
