Amazon.com Inc (NASDAQ:AMZN) will launch its first two prototype satellites for a planned internet-from-space constellation in early 2023 using a new rocket from the Boeing-Lockheed joint venture, United Launch Alliance (ULA), the two companies said in a statement on Wednesday. The prototype satellites will be the first to launch as part of Amazon's Kuiper network, a planned constellation of 3,236 low-Earth orbiting satellites designed to beam broadband internet to remote parts of the world.
