Watch the SpaceX Falcon 9 rocket launch the EchoStar 23 satellite

Forecasting a future where satellite networks reach into vastly more ships, airplanes, homes and businesses, SES announced Monday it will buy at least seven high-capacity broadband and data relay satellites from Boeing for launch in 2021 into a rarely-used orbit several thousand miles over the equator.

Watch in 4K video was SpaceX test-fires a Falcon 9 rocket ahead of an upcoming in-flight test of the Crew Dragon’s emergency escape rockets.

SpaceX called off a Falcon 9 countdown Wednesday due to the threat of lightning from thunderstorms along Florida’s Space Coast, pushing back the departure of a cargo mission for the International Space Station until Thursday.
