Aditya L1 Science Quiz: ISRO is all set to launch its first solar mission on September 2 at 11:50 am from the Sriharikota spaceport. This spacecraft will be placed in the halo orbit around the Lagrange point 1(L1) of the Sun-Earth system. It will help to observe and understand solar activities and their effect on space weather. According to ISRO, “The suits of Aditya L1 payloads are expected to provide most crucial information to understand the problem of coronal heating, coronal mass ejection, pre-flare and flare activities and their characteristics, dynamics of space weather, propagation of particle and fields etc.”
