Mission insignia

Chandrayaan-3 ( CHUN-drə-YAHN) is the third mission in the Chandrayaan programme, a series of lunar-exploratio/ˌtʃʌndrəˈjɑːn/n missions developed by the Indian Space Research Organisation (ISRO).[11] The mission consists of a Vikram lunar lander and a Pragyan lunar rover was launched from Satish Dhawan Space Centre on 14 July 2023. The spacecraft entered lunar orbit on 5 August, and India became the first country to touch down near the lunar south pole, at 69°S, the southernmost lunar landing [12] on 23 August 2023 at 18:04 IST (12:33 UTC), ISRO became the first agency to land on the south pole of the moon in its first attempt and overall the fourth space agency to successfully land on the Moon, after USSR, NASA and the CNSA .[13][note 1]

Chandrayaan-3 was launched from Satish Dhawan Space Centre on 14 July 2023. The spacecraft entered lunar orbit on 5 August, and became the first lander to touch down near the lunar south pole[12] on 23 August at 18:03 IST (12:33 UTC), making India the fourth country to successfully land on the Moon, and at 69°S, the southernmost lunar landing, until IM-1 landed further southwards in Malapert A crater on 22 February 2024.[13][note 2] The lander was not built to withstand the cold temperatures of the lunar night, and sunset over the landing site ended the surface mission twelve days after landing.[17][18] The propulsion module, still operational, transited back to a high Earth orbit from lunar orbit on 22 November 2023 for continued scientific observations of Earth.[19] It operated until 22 August 2024.[4]
