SpaceX is launching about 240 satellites per month. This will mean that SpaceX will have about 3400 satellites in orbit by the end of 2021 by sustaining this pace. If SpaceX is able to increase the frequency of Starlink launches to once every four days then they would have 4400 satellites deployed by the end of 2021. If SpaceX is able to increase the Starlink launches in 2022 to once every three days then they would have 7200 additional satellites deployed by the end of 2022.
