First launch of 60 Starlink test satellites. Said to be "production design", these are used to test various aspects of the network, including deorbiting. They do not yet have the planned satellite interlink capabilities and they only communicate with antennas on Earth. A day after launch an amateur astronomer in the Netherlands was one of the first to publish a video showing the satellites flying across the sky as a "train" of bright lights. By five weeks post launch, 57 of the 60 satellites were "healthy" while 3 had become non-operational and were derelict, but will deorbit due to atmospheric drag. As of 17 September 2020, most satellites have been deorbited or sent to a much lower orbit.
