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.

Why Nobody Can See What Is Happening Near the Moon
The volume of space between Earth and the Moon is roughly a thousand times larger than the orbit we actually watch, and almost none of it is under surveillance. As the U.S. and China race to build lunar outposts, the Space Force is scrambling to put eyes on a region it has been effectively blind to.

The Pentagon's Mystery Spaceplane Takes Off
On April 22, 2010, an Atlas V lifted off from Cape Canaveral carrying a reusable robotic spaceplane so secret that the Air Force would not even confirm its mission duration. It came back 224 days later, lighter, quieter, and more operational than anyone outside Washington had expected. Fifteen years later, the X-37B is still flying, and the military still will not say what it does.
