Optical Intersatellite Link (OISL)
The laser-based crosslinks that turn Starlink into a mesh, anchor the SDA Transport Layer, and just made their GPS debut on GPS III SV10 - quietly rewriting how data moves through space.

Summary
Starlink is a satellite constellation developed by SpaceX with the aim of providing global broadband internet coverage. Thousands of small satellites are deployed in low Earth orbit (LEO), enabling high-speed internet access even in remote areas. However, the rapid increase in satellites raises concerns about space debris and the potential for collisions, which can lead to further debris creation and endanger other spacecraft. Additionally, the sheer number of Starlink satellites can affect astronomical observations by increasing light pollution. Proper deorbiting plans and international coordination are essential to mitigate these challenges and ensure long-term sustainability in space.
