Aditya L1 Science Quiz: ISRO is all set to launch its first solar mission on September 2 at 11:50 AM from Sriharikota Spaceport. This spacecraft will be placed in a halo orbit around the Lagrange point 1(L1) of the Sun-Earth system. It will help in observing and understanding solar activities and their influence on space weather. According to ISRO, the Aditya L1 payload suits are expected to provide the most important information to understand the problems of coronal heating, coronal mass ejection, preflare and flare activity and their characteristics, space weather dynamics, particle and field propagation, etc.”
PSLV-C57/Aditya-L1 mission: 23 hours and 40 minutes countdown to launch at 11:50 am. IST on September 2, 2023, was commended today at 12:10 PM.
The launch can be followed LIVE on ISRO website https://t.co/osrHMk7MZL Facebook https://t.co/zugXQAYy1yYouTube…
