SpaceX test-fired nine Merlin engines Saturday before the company’s next launch from Cape Canaveral, clearing a key readiness test before liftoff as soon as Sunday night with 60 more Starlink internet satellites.

SES announced Thursday it has tapped SpaceX for two additional Falcon 9 rocket launches from Cape Canaveral to deliver more Boeing-built O3b mPower broadband satellites into orbit, adding to a pair of Falcon 9 flights ordered by SES last year to launch the first batch of mPower platforms beginning in late 2021.

More than three years after its launch was delayed by a corporate merger, a commercial Earth-imaging satellite has finally shipped to its California rocket base for liftoff aboard an Atlas 5 in September.
