On Monday, the company filed a license application with the Federal Communications Commission to launch two prototype satellites, KuiperSat-1 and KuiperSat-2. They will feature many of the technologies the company plans to include in the final production variant of its constellation satellite, giving it the chance to test how those systems fare outside of a lab environment. At the same time, the tests will allow it to validate its launch procedures and mission management when it comes time to start putting its full network in orbit."We’ve invented lots of new technology to meet our cost and performance targets for Project Kuiper. All of the systems are testing well in simulated and lab settings, and we’ll soon be ready to see how they perform in space," said Rajeev Badyal, vice president of technology for Project Kuiper. "There is no substitute for on-orbit t
