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.

For 56 years, April 22 has been the day the world stops to look at itself. Before that was possible, someone had to invent the view. This is the story of how we first saw Earth from the outside, from a crashed V-2 camera in the New Mexico desert to the Blue Marble that still hangs on classroom walls.
