 It's space-traffic time and it's a week full of Earth departures. First up, CentiSpace One S3 and S4 launched on this Kuizhou 1A rocket from the Zhiguang satellite launch centre in China at 02.24 UTC on September 6th. The satellites are commercial small satellites from the company Future Navigation, which will provide satellite navigation services from low Earth orbit. If this test is successful, Future Navigation wants to put 160 satellites into orbit for a navigation constellation.
