Welcome to the Astrosat Science Support Cell (ASSC), operated jointly by the Indian Space Research Organisation (ISRO) and the Inter-University Centre for Astronomy and Astrophysics (IUCAA). The ASSC assists Guest Observers in making observing proposals and analyzing the science data acquired by the AstroSat mission. This site provides tools and documentation required for proposal writing and data analysis, along with necessary updates. The ASSC also organizes workshops/meetings and operates a helpdesk. The ASSC works in close collaboration with the Indian Space Science Data Centre (ISSDC) and the Payload Operation Centres of UVIT, LAXPC, SXT, and CZTI instruments.
