Space debris, also known as space junk, is a growing problem in our solar system. It consists of man-made objects that are no longer functioning properly or are in orbit around Earth or other planetary bodies. As the number of these objects increases, so does the risk of collisions with active satellites and spacecraft. This can lead to damage or even destruction of the equipment, as well as putting astronauts and cosmonauts at risk.
The problem of space debris has been increasing over the years as more and more countries have launched satellites and other objects into orbit. In addition, the amount of time that these objects spend in orbit has increased due to advances in technology. As a result, there are now an estimated 9,000 tons of man-made material orbiting Earth, including everything from spent rocket stages to dead satellites.
Most space debris is found in low Earth orbit (LEO), which extends from about 160 kilometers (100 miles) to 2,000 kilometers (1,200 miles) above our planet’s surface. LEO is a popular spot for satellites because it provides a good balance between being close enough to Earth for easy communications and far enough away to avoid most of our planet’s weather disturbances. However, it also means that any debris that collides with a satellite in this region will likely come down to Earth eventually.
The Kessler Syndrome is a theoretical scenario where the density ofobjects in LEO becomes so high that collisions become increasinglylikely, creating more debris which then leads to even more collisionsin what becomes a cascading effect leading to the eventual breakdowndownof the entire LEO region.. Such an event could render LEO unusablefor many years and cause billions if not trillionsof dollars inn damages.. While this scenario is still consideredunlikely by most experts,, it highlights just how seriousthe problemof space junk has become..
