Aditya L1 is an Indian solar observation satellite to be placed at the Sun-Earth Lagrangian point L1. The major scientific objectives of the mission are to achieve a fundamental understanding of the physical processes that heat the solar corona, accelerate the solar wind and produce Coronal Mass Ejections (CMEs). Originally the mission design started as a small LEO satellite carrying only a coronagraph as a payload. In order to get the best science from the Sun, continuous viewing of the Sun is preferred. A Satellite placed in the halo orbit around the L1 Lagrangian point of the Sun-Earth system has the major advantage of continuously viewing the Sun without any occultation/ eclipses.
