A powerful rocket sent the first batch of 27 satellites for Amazon’s Project Kuiper broadband internet network into low Earth orbit today, marking a milestone in the company’s multibillion-dollar bid to catch up with SpaceX’s Starlink constellation.
Today’s liftoff came nearly three weeks after the first attempt was scrubbed due to weather concerns. This time, the clouds and rain showers stayed far enough away for United Launch Alliance to launch its Atlas V rocket from Cape Canaveral Space Force Station in Florida at 7:01 p.m. ET (4:01 p.m. PT). ULA used its most powerful version of the Atlas, with five solid-rocket boosters attached to the first stage.
“Go Atlas … Go Centaur … Go KA-01,” launch managers declared in the final seconds before liftoff.
The rocket’s Centaur upper stage delivered Amazon’s satellites to an altitude of 280 miles (450 kilometers). In a posting to Threads, ULA said the satellites were deployed successfully. And in an online update, Amazon said its team “established contact with all 27 satellites, and initial deployment and activation sequences are proceeding nominally.”
The satellites will use their onboard electric propulsion systems to settle into their final intended orbits of 392 miles (630 kilometers) under the management of Project Kuiper’s mission operations team in Redmond, Wash.
