Watch the SpaceX Falcon 9 rocket launch the EchoStar 23 satellite

A test-firing of a twice-flown Falcon 9 booster Friday at Cape Canaveral paved the way for SpaceX’s next launch, scheduled for Monday night with a heavyweight Boeing-built communications satellite to beam broadband signals to Japan and the Pacific islands.

The Starlink 6-83 mission will also mark SpaceX’s 100th Falcon 9 launch from Launch Complex 39A. Liftoff is targeted for Tuesday, May 13, at 1:02 a.m. EDT (0502 UTC).

Technicians working at launch pad 0A at NASA’s Wallops Flight Facility in Virginia completed the final loading of cargo into Northrop Grumman’s Cygnus supply ship late Tuesday, and the Antares rocket was raised vertical again in preparation for Wednesday’s countdown.
