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 Multi-Orbit Myth? Why One Startup Thinks the Satellite Industry Got It Wrong
The satellite industry's biggest operators are betting on multi-orbit architectures that combine LEO, MEO, and GEO into unified networks. A San Francisco startup called Contrivian thinks they've overcomplicated the problem, and the physics might be on its side.
