A United Launch Alliance Atlas 5 rocket will send one of Viasat’s next-generation broadband satellites toward geostationary orbit from Cape Canaveral some time between 2020 and 2022, the companies announced Monday.

SpaceX test-fired the Falcon 9 rocket early Saturday ahead of launch with the next four astronauts heading to the International Space Station. The static fire test before sunrise Saturday in Florida was a major step toward liftoff Thursday.

The newest Global Positioning System replenishment satellite went into operation Tuesday night, five weeks after ascending to space from Cape Canaveral atop a United Launch Alliance Atlas 5 rocket.
