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 Civilian Space Traffic System America Almost Didn't Build
For nearly two decades, the U.S. Air Force and Space Force have been the world's unofficial civilian space traffic control system. The Department of Commerce's Traffic Coordination System for Space (TraCSS) is now taking over that job for commercial satellite operators - in stages, against persistent congressional pressure to kill the program, and with Department of Defense advocates pushing to make it happen before it is too late.
