The document discusses space debris, which consists of objects in Earth's orbit that no longer serve a useful purpose, such as non-functioning satellites, rocket stages, and fragments from collisions or explosions. There are currently over 300,000 objects estimated to be flying over the planet, and the amount is increasing by 5% each year. Two events in particular have increased space debris: a 2007 Chinese anti-satellite missile test that created over 15,000 fragments, and a 2009 collision between two objects that led to additional fragments. The growing amount of debris poses risks like the Kessler syndrome and can damage functioning spacecraft. Proposed solutions include debris collection nets and using ground-based lasers to divert objects.
