Starlink is the largest satellite constellation ever deployed — and it's continuously growing, as today's planned launch demonstrates. There are currently more than 6,850 active Starlink spacecraft in LEO, according to satellite tracker and astrophysicist Jonathan McDowell.

SpaceX has launched its last mission of the year. A Falcon 9 rocket topped with 21 Starlink broadband internet satellites, including 13 with direct-to-cell capability, lifted off from Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center in Florida on Tuesday (Dec. 31). The launch occurred at 12:34 a.m. EST (0534 GMT).
