Although the space age has brought about many benefits for all humankind, these benefits have not come without consequences. Space-faring nations are creating environmental damages that could have long-term effects. The most immediate of these is space debris, the nonfunctional satellites, launch vehicles and related objects that orbit the Earth uncontrolled.
On 10 February 2009, an inactive Cosmos-2251 satellite and an active commercial Iridium-33 satellite collided in low-Earth orbit at an altitude of about 800 kilometres above Siberia. This created a large cloud of space debris, which could remain in orbit possibly for decades and continue threatening other active satellites. The loss of Iridium-33 disrupted telecommunication service to a section of Iridium customers.
The growing awareness of the impact of space debris upon the safety of space operations and space-based assets has encouraged some space actors to take steps to mitigate the production of new debris through the development and implementation of national and international debris mitigation measures. In 2007, the United Nations Committee on Peaceful Uses of Outer Space (COPUOS) adopted Space Debris Mitigation Guidelines, which were subsequently endorsed by the UN General Assembly (hereinafter referred to as UN COPUOS Guidelines).
