Watch the Falcon 9 test fire its engines ahead of Starlink launch (members only)

Another 60 Starlink internet satellites rumbled into orbit aboard a Falcon 9 rocket early Wednesday from Cape Canaveral Space Force Station in Florida, the 25th mission to launch spacecraft for SpaceX’s broadband network.

SpaceX launch crews rolled out the company’s next Falcon 9 rocket to pad 39A at the Kennedy Space Center in Florida, then lifted the two-stage launcher vertical for a hold-down engine firing Thursday in preparation for launch next week with a South Korean-owned commercial communications satellite.

With an eye on dangerous Hurricane Irma’s forecast path toward Florida, SpaceX and the U.S. Air Force are proceeding with preparations to launch an unpiloted reusable military spaceship Thursday on a mission to conduct experiments in orbit, deploy multiple small satellites and glide back to Earth for a runway landing after months or years in space.
