Another set of Starlink Internet satellites launched Tuesday from Cape Canaveral aboard a SpaceX Falcon 9 rocket. Powered by a reusable first stage booster making its sixth flight, the Falcon 9 rocket lifted off at 10:31 a.m. EDT (1431 GMT). Three SkySat Earth-imaging satellites for Planet accompanied SpaceX’s 58 Starlink relay stations into orbit.
