Elon Musk has shown a stack of sixty Starlink Satellites in a SpaceX Falcon 9 that will soon be launched. SpaceX will be able to start operating the Starlink network with 800 Starlink satellites. It would take fourteen launches to get over 800 Starlink satellites. These 60 satellites are prototypes which may not be good enough for the commercial service.
Each Falcon 9 launch will cost SpaceX about $30-40 million. SpaceX charges $50 million for each launch but SpaceX has a profit margin. Each Starlink satellite will cost about $1 million to launch and likely costs about $1-2 million to build.
