European Space Agency Activities on Orbital Debris
Despite reduced launch activities and application of debris control measures, the space debris population in orbit is steadily growing with a corresponding increase of the hazard. New aspects are introduced with multi-satellite constellations in low Earth orbit (LEO) and the increased use of micro-satellites, which present an increasing challenge for space debris mitigation. As a consequence the priorities of the Agency's space debris policy as adopted in 1989 will also have to be directed towards paying more attention to the near Earth orbit region with its more dense debris population. ESA's space debris activities are reviewed regularly by the Council and adapted to new developments.
