Artificial asteroid belt risks space access
The European Space Agency has confirmed that humans are continuing to build an "artificial asteroid belt" around the Earth, consisting of thousands of satellites, in addition to millions of fragments and space debris resulting from collisions of old satellites and orbital interactions. Since 1957, humanity has launched approximately 27,490 artificial satellites, with around 18,840 still in orbit. There are also more than 50,000 pieces of debris larger than 10 centimeters, posing significant risks to spacecraft. The density of debris is especially increasing in low Earth orbits approaching an altitude of 550 kilometers, where collision risks become higher, requiring continual maneuvering and threatening the long-term sustainability of the space environment, with more than a million pieces measuring a centimeter or larger scattered around Earth.
