Summary
Space debris, also known as space junk, encompasses all non-functional objects orbiting Earth such as defunct satellites, spent rocket stages, and fragments from collisions or disintegrations. Over time, this debris can accumulate and create an increasingly hazardous environment in orbit. Even tiny fragments, traveling at extremely high velocities, can inflict significant damage on operational satellites and spacecraft. If left unmanaged, the density of debris raises the risk of catastrophic collisions and further fragmentation, compounding the problem and threatening the safety and sustainability of space activities.

The Telescope That Needed Glasses
On April 25, 1990, the Space Shuttle Discovery's robotic arm lifted a 11,110-kilogram barrel of mirrors and instruments out of the payload bay and released it into orbit. Six weeks later, the first images came back badly out of focus. The Hubble Space Telescope had been ground to the wrong prescription, and America had just spent $2.5 billion on what the press was calling a 'technoturkey.'
