The first Starlink prototype satellites were put into orbit in 2018. There have been more than 20 successful launches since then, bringing the total number of satellites launched to nearly 1,300 as of February 2021. SpaceX put some of the satellites into orbit using the Falcon 9 orbital rocket.
Eventually, Starlink hopes to surround the entire planet with satellites that can broadcast a high-speed, usable Wi-Fi signal. Starlink will likely need at least 10,000 satellites in orbit to achieve that goal. SpaceX has suggested it wants up to 30,000 satellites in the constellation, while Musk has claimed the service should be available worldwide sometime in 2022, if it can successfully complete several more satellite launches.
