After Moon, Isro sets its sight on Sun as the space agency gears up to launch Aditya Li mission two weeks from now. Isro chair man S Somanath said the "Ad- tiya Li mission is in the works and will be ready for launch in the first week of September".

The spacecraft will embark on a 127-day-long journey to re- ach its destination, which will cover a distance of nearly 15 lakh km from the Earth.

Aditya Li will be the first space-based Indian mission to will be placed in a halo orbit around the Lagrange point 1 (a) of the Sun-Earth system. According to an Isro official,

A satellite placed in the ha- lo orbit around the L1 point has the major advantage of contin- uously viewing the Sun with out any occultation or eclips es. This will provide a greater advantage of observing the so- lar activities and its effect on space weather in real time.

The biggest challenge is the distance of the Sun from the Earth (approx 15 crore km on average, compared to only 3.8 lakh km to the Moon). Due to the risks involved, payloads in earlier Isro missions have lar gely remained stationary in sp- ace. However, Aditya Ll will ts, which increase the risks of collision. Other issues are su- per hot temperatures and radi ation in the solar atmosphere.
