Summary

A rocket body, also commonly referred to as an upper stage or spent rocket stage, is the structural shell left behind after a rocket has delivered its payload to orbit. These large and often heavy pieces of space hardware can remain in orbit for years, posing significant collision hazards as part of the growing space debris problem. If left uncontrolled, rocket bodies have the potential to reenter Earth's atmosphere unpredictably, which can lead to falling debris in populated areas. Additionally, they risk colliding with operational satellites or the International Space Station, creating more debris and putting human life at risk.

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.
