| description abstract | The L2 Sun-Earth Lagrange point or L2 point, some 1 500 000 km from the Earth, provides a radio-quiet environment and stable orbits that are used for space-based radio astronomy and space research service (passive) missions. Some such missions are currently using the L2 point, and more are planned. This Recommendation provides timely supporting information and reiterates the importance of preserving the radio-quiet environment of the L2 point as a basis for future space-based radio astronomy missions. | |
