Two Falcon 9 rockets lifted off from spaceports in Florida and California on Sunday afternoon, including 56 extra satellites to SpaceX's Starlink broadband community.
The second of those two launches—originating from Vandenberg Area Pressure Base, California—propelled SpaceX's Starlink program previous a notable milestone. With the satellites added to the constellation Sunday, the corporate has delivered greater than 10,000 mass-produced Starlink spacecraft to low-Earth orbit.
The precise determine stands at 10,006 satellites, in accordance with a tabulation by Jonathan McDowell, an astrophysicist who expertly tracks comings and goings between Earth and house. This quantity contains dozens of Starlink demo satellites, however not the dummy spacecraft carried on SpaceX's current Starship take a look at flights.
The Starlink community surpassed 7 million world subscribers in August, primarily beaming Web connectivity to houses and companies. SpaceX is now aggressively pushing to broaden its service direct to smartphones.
The primary two Starlink prototypes, named Tintin A and Tintin B, launched in 2018 as pathfinders. SpaceX started launching Starlink satellites with a radically totally different design in 2019, initially flying 60 satellites at a time. The variety of spacecraft per launch has gone down because the satellites grew bigger and extra succesful, with the Falcon 9's capability now maxed out at 28 satellites per flight.

SpaceX's launch director nodded in the meanwhile the Falcon 9 took off from California Sunday: “From Tintin to 10,000. Go Starlink, go Falcon, go SpaceX.”
Slightly greater than an hour later, SpaceX confirmed the profitable deployment of the rocket's 28 satellites about 160 miles (260 kilometers) above the Earth. They had been anticipated to unfurl their photo voltaic arrays and activate their plasma engines to start climbing to their operational altitude of 332 miles (535 kilometers).
By the numbers
SpaceX is decommissioning growing old and out of date Starlink satellites as the corporate provides to the fleet. The retired satellites reenter the atmosphere, the place they're designed to expend with none particles reaching the bottom. Considering all of the reentries, listed here are McDowell's numbers for the Starlink fleet because it stands Monday, October 20:
- 8,680 whole Starlink satellites in orbit
- 8,664 functioning Starlink satellites in orbit (together with newly launched satellites not but operational)
- 7,448 Starlink satellites in operational orbit
