• Aditya L1 mission will be launched to study Sun’s corona (Visible and Near infrared rays), chromosphere (Ultra Violet), Sun’s photosphere (soft and hard X-ray), solar winds & flares, solar emissions, and Coronal Mass Ejections (CMEs). It will also carry out round-the-clock imaging of the Sun.

• This mission is significant because, it is important to study the Sun in light that, evolution of planets and exoplanets beyond the Solar System is governed by the Sun. Solar weather and environment affect the weather of entire system.

• It will help in studying the Effects of Variation in Solar Weather System. Variations in this weather can change orbits of satellites or even shorten their lives.

• It will help in learning about and tracking Earth-directed storms.

• The Aditya-L1 mission will be placed into a point called L1 Lagrange point.

• This mission will be ISRO’s 2nd space-based astronomy mission after AstroSat. It was launched in 2015.

• Aditya-L1 was earlier named as Aditya 1 and was meant to observe only the solar corona.

• Solar probe, Aditya L1 will be launched on Polar Satellite Launch Vehicle (PSLV) XL, carrying 7 payloads or instruments on board.
