Scientific Purpose of the Mission 

It aims to study solar upper atmosphere dynamics, heating processes, coronal mass ejections (CMEs), and flares and analyse particle dynamics and magnetic fields to understand solar-driven space weather drivers.

Purpose of its 7 Payloads

The seven payloads on Aditya L1 have two main purposes: four allow for direct solar viewing and three facilitate in-situ observations. Notably, VELC (Visible Emission Line Coronagraph) provides 1440 images to ground stations every day.
