Starlink
Thousands of satellites, one constellation, and a new argument about who controls the sky.
What it is
Starlink is SpaceX’s satellite-internet constellation: thousands of small satellites in low Earth orbit beaming broadband to user terminals on the ground. First launches in 2019; public beta in October 2020. It became the largest satellite constellation ever flown, with subscriber counts in the millions by the mid-2020s.
Why it mattered
Rural areas, ships, disaster zones, and war zones got broadband where fiber and cell towers couldn’t reach. In February 2022, after Russia’s invasion of Ukraine, Musk shipped Starlink terminals to Ukraine — a move widely credited with keeping the country’s communications alive.
The controversies
- Astronomy: Astronomers protested that satellite trains were ruining observations; SpaceX added sunshades and darker coatings (partial mitigation, ongoing debate).
- Ukraine/Crimea: The 2022–2023 dispute over whether Musk refused to extend coverage for a Ukrainian operation near Crimea. Accounts differ (see Mythology vs. Record); a 2023–2024 Pentagon contract later formalized military use.
- Market power: Critics argue one company controlling the dominant constellation is a geopolitical risk; SpaceX argues no one else built it.
The business
Starlink became SpaceX’s revenue engine — analysts have estimated it funds Starship development. It turned SpaceX from a launch company into a telecom.
