Mission Insignia

Aditya-L1 (Sanskrit: Āditya IPA: [aːd̪it̪jɐ] 'Sun', L1 'Lagrange Point 1') [a] is a coronagraphy spacecraft for studying the solar atmosphere, designed and developed by the Indian Space Research Organisation (ISRO) and various other Indian Space Research Institutes.[1] It is orbiting at about 1.5 million km from Earth in a halo orbit around the Lagrange point 1 (L1) between the Earth and the Sun, where it will study the solar atmosphere, solar magnetic storms, and their impact on the environment around the Earth.[7]

It is the first Indian mission dedicated to observe the Sun. Nigar Shaji is the project's director.[8][9][10][11] Aditya-L1 was launched aboard the PSLV C57 at 11:50 IST on 2 September 2023.[12][3][4] It successfully achieved its intended orbit nearly an hour later, and separated from its fourth stage at 12:57 IST.[13] It was inserted at the L1 point on 6 January 2024, at 4:17 pm IST.[14]
