PSLV-XL: Aditya-L1

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.

About PSLV XL

PSLV-XL is the upgraded version of Polar Satellite Launch Vehicle in its standard configuration boosted by more powerful, stretched strap-on boosters with 12 tonne propellant load. Weighing 320t at lift-off, the vehicle uses larger strap-on motors (PSOM-XL or S12) to achieve higher payload capability. On 29 December 2005, ISRO successfully tested the improved version of strap-on booster for the PSLV. The first use of PSLV-XL was the launch of Chandrayaan-1 by PSLV C11. The payload capability for this variant is 1,800 kg to SSO.
