Space Debris and International Cooperation Space debris is one of the most serious and paradoxical problems that humanity has faced in the space age. It is unique: it was created exclusively by us, it threatens everyone without discrimination, and no single country is capable of solving it alone. This problem has rapidly transformed from a purely technical one into a global one, requiring unprecedented levels of international cooperation. The Scale of the Threat: An Invisible Danger Space debris (a technical term for "space objects of anthropogenic origin, non-functional in space") includes spent satellites, launch vehicles, fairings, fragments from explosions and collisions, bolts, tools lost by astronauts, and even tiny paint particles. According to data from the U.S. Space Command, more than 45,000 objects larger than 5-10 centimeters are currently being monitored in low Earth orbit. Their actual number is orders of magnitude greater: according to the European Space Agency (ESA), there are about 1 million fragments 1-10 cm in size and over 130 million particles smaller than 1 cm in orbit. The danger lies in the colossal kinetic energy. On the low Earth orbit (LEO), where the bulk of the debris is concentrated, objects move at speeds of about 7-8 km/s (up to 28,000 km/h). At such speeds, a particle the size of a pea has the energy of a truck moving at full speed, and a bolt can pierce through the hull of the ISS or a functional satellite. Key Catastrophes and the Kessler Effect Two major milestones in the history of space pollution are the tests of anti-satellite weapons. In 2007, China destroyed its old meteorological satellite "Fengyun-1C" with a missile, creating more than 3,500 trackable fragments that still pose a serious threat. This single act increased the population of space debris in LEO by 25%. In 2009, the first unintentional collision of two large objects occurred: the active American communication satellite Iridium-33 and the non-functional Russian m ... Read more
