• On September 2, 'Aditya-L1' Surya Mission was launched from the Satish Dhawan Space Center in Sriharikota by the Indian Space Research Organization (ISRO) to study the Sun.
• Aditya L-1 will be placed near the L-1 Lagrange point between the Sun and the Earth.
• This mission has been launched through the XL version rocket of PSLV-C57.
•  'Aditya L-1' is India's first space mission to study the Sun.

 Lagrangian point-1

• L1 refers to Lagrangian/Lagrange Point 1, one of 5 points in the orbital plane of the Earth-Sun system.
• A Satellite placed in the halo orbit around the L1 has the major advantage of continuously viewing the Sun without any occultation/ eclipses.

 Objective:

• Aditya L1 will study the Sun’s corona, Sun's photosphere, chromosphere, solar emissions, solar winds and flares, and Coronal Mass Ejections (CMEs), and will carry out round-the-clock imaging of the Sun.

Significance:

• It will help in studying the temperature, velocity and density of the corona and also help in measuring the magnetic field of the corona and studying the evolution and origin of coronal mass ejections.
