Starlink is a satellite internet constellation operated by SpaceX.[2] It provides satellite Internet access coverage to 32 countries where its use has been licensed, and aims for global coverage.[3][4] As of May 2022 Starlink consists of over 2,300 mass-produced small satellites in low Earth orbit (LEO), which communicate with designated ground transceivers.
The SpaceX satellite development facility in Redmond, Washington, houses the Starlink research, development, manufacturing, and orbit control teams. The cost of the decade-long project to design, build, and deploy the constellation was estimated by SpaceX in May 2018 to be at least US$10 billion.[5] In February 2017, documents indicated that SpaceX expects more than $30 billion in revenue by 2025 from its satellite constellation, while revenues from its launch business were expected to reach $5 billion in the same year.[6][7]
On 15 October 2019, the United States Federal Communications Commission (FCC) submitted filings to the International Telecommunication Union (ITU) on SpaceX's behalf to arrange spectrum for 30,000 additional Starlink satellites to supplement the 12,000 Starlink satellites already approved by the FCC.[8]
Some astronomers have raised concerns about the constellations' effect on ground-based astronomy and how the satellites will add to an already congested orbital environment.[9][10] SpaceX has attempted to mitigate astronomy concerns by implementing several upgrades to Starlink satellites aimed at reducing their brightness during operation.[11] The satellites are equipped with krypton-fueled Hall thrusters which allow them to de-orbit at the end of their life. Additionally, the satellites are designed to autonomously avoid collisions based on uplinked tracking data.
