Amazon has successfully launched its first satellites for the company’s Project Kuiper internet-from-space service, which will take on SpaceX’s Starlink service.

Amazon has launched the first batch of satellites for its broadband internet constellation, Project Kuiper, as it tries to get a rival network to Elon Musk’s Starlink off the ground. The 27 Kuiper satellites were blasted into space aboard launch provider United Launch Alliance’s Atlas V rocket from Cape Canaveral in Florida, ULA said on Monday.
