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 Satellite That Found 22 Photons and Changed Astronomy
On April 27, 1961, a Scout rocket lifted a 37-kilogram NASA satellite into orbit from Wallops Island carrying the first serious instrument for detecting cosmic gamma rays. Explorer 11 operated for seven months before its tape recorder failed. In that time it registered 22 gamma-ray photons - a pitiful number by modern standards, but enough to launch an entire branch of astronomy.
GOES-19, the Last Weather Sentinel
The final satellite in a multi-billion-dollar program that learned its hardest lesson from a clogged pipe. GOES-19 is now NOAA's eyes on every Atlantic hurricane - and it's already found dozens of comets no one was looking for.
