Watch the SpaceX Falcon 9 rocket launch the EchoStar 23 satellite

SpaceX’s next launch of satellites for the company’s Starlink broadband network — planned in the final days of 2019 — will carry one spacecraft with an experimental coating designed to make it less reflective in orbit, a first step in assuaging concerns from scientists who say the deployment of thousands more Starlink stations would impede some astronomical observations.

A new satellite built to extend a 24-year series of joint U.S.-European ocean observatories climbed away from a foggy California launch pad and sailed into orbit more than 800 miles above Earth on Sunday aboard a SpaceX Falcon 9 rocket.

These photos follow the Falcon 9 rocket and Dragon spacecraft through a final rehearsal, the late stowage of cargo, and finally the lifting of the launcher vertical atop pad 39A at NASA’s Kennedy Space Center in Florida.
