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.

STS-51B | Three-Tenths of a Second from Disaster
Forty years ago today, Challenger lifted off LC-39A on a science mission that nobody outside Morton-Thiokol would call dangerous. Years later, after the orbiter and seven other astronauts were gone, investigators looked at the recovered boosters from STS-51B and realized the crew had come within a fraction of a second of dying first. This is the story of the launch that should have been a warning.
