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
Space debris, also known as space junk, encompasses all non-functional objects orbiting Earth such as defunct satellites, spent rocket stages, and fragments from collisions or disintegrations. Over time, this debris can accumulate and create an increasingly hazardous environment in orbit. Even tiny fragments, traveling at extremely high velocities, can inflict significant damage on operational satellites and spacecraft. If left unmanaged, the density of debris raises the risk of catastrophic collisions and further fragmentation, compounding the problem and threatening the safety and sustainability of space activities.
