About ALISC

• ISRO and ARIES collaborated on this project. The acronym ISRO stands for Indian Space Research Organization, and ARIES stands for Aryabhatta Research Institute for Observational Sciences.

• The Centre will house visiting observers and assist them in analyzing the mission's observations by providing data from the mission.

• It would consolidate all of the mission's data into a single interface.

Aditya-L1

• The Aditya-1 mission was conceived as a 400kg class satellite carrying one payload, the Visible Emission Line Coronagraph (VELC), and was planned to launch in an 800 km low earth orbit.

• A Satellite placed in the halo orbit around the Lagrangian point 1 (L1) of the Sun-Earth system has the major advantage of continuously viewing the Sun without any occultation/ eclipses.
