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.

The 300,000 Swerves Keeping Low Earth Orbit From Crashing

Starlink satellites fired their thrusters to dodge a collision roughly 300,000 times in 2025, about 822 times a day. Behind that number is a fragile, half-automated system of warnings, probabilities, and judgment calls that decides which close approaches are worth a maneuver and which are just noise.
