Watch the Falcon Heavy roar to life

SpaceX’s Falcon 9 rocket was poised for launch Wednesday at Cape Canaveral’s Complex 40 launch pad carrying more than 5,600 pounds of supplies and experiments to the International Space Station.

SpaceX launched 60 more Starlink internet relay platforms into orbit Sunday as the company ramps up network testing in Washington state and touts a streak of nearly 300 satellites launched since June without a spacecraft failure.

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.
