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.

The Rocket That Refused to Sink

On April 18, 2014, a Falcon 9 first stage did something no orbital rocket had ever done before. It fired its engines on the way down, steered itself through the atmosphere using grid fins that did not yet exist, and touched the Atlantic Ocean softly enough to survive the impact. Nobody recovered it. The data was the whole point.
