A Falcon 9 rocket with a reusable first stage and ten Iridium communication satellites on board blasted off Friday from a site in California.
The satellites were placed into low-earth orbit and returned "healthy signals" less than two hours after the launch, according to the company’s Twitter feed.
"Successful deployment of 10 IridiumComm NEXT satellites to low-Earth orbit confirmed," the spacecraft manufacturer, founded by inventor Elon Musk, announced.
The rocket was launched from Vandenberg air force base at 5:27 p.m. local time (01:27 GMT Saturday).
This is the fourth time SpaceX launches a dozen of Iridium satellites to replace a constellation of more than 70 orbiting the Earth.Sputnik
