Photos: Delta 4 rocket fires off the pad before sunset

SpaceX raised a Falcon 9 rocket vertical Tuesday on pad 39A at NASA’s Kennedy Space Center, positioning the launch vehicle for a flight Wednesday carrying 57 more Starlink Internet satellites and two commercial Earth-imaging microsatellites for BlackSky.

Arianespace has announced OneWeb, the broadband Internet provider seeking to deploy more than 600 satellites into low Earth orbit, as the launch customer for the inaugural flight of the new Ariane 6 rocket in 2020.

This is the launch timeline to be followed by the Atlas 5 rocket’s ascent into orbit from Cape Canaveral with the EchoStar 19 satellite for HughesNet’s direct-to-home Internet connectivity. Launch is scheduled for Sunday at 1:27 p.m. EST (1827 GMT).
