(Sanskrit: चन्द्रयान-२; Sanskrit: [t͡ɕən̪d̪ɾəjaːna d̪ʋi]; lit: Moon-craft[14][15] About this sound pronunciation (help·info)) is India's second lunar exploration mission after Chandrayaan-1.[16] Developed by the Indian Space Research Organisation (ISRO),[17][18] the mission was launched from the second launch pad at Satish Dhawan Space Centre on 22 July 2019 at 2.43 PM IST (09:13 UTC) to the Moon by a Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk III). [19][8][9]The planned orbit has a perigee of 170 km and an apogee of 45475 km. It consists of a lunar orbiter, a lander, and a lunar rover named Pragyan, all developed in India.[20] The main scientific objective is to map the location and abundance of lunar water. The lander and the rover will land near the lunar south pole region in a high plain between two craters, Manzinus C and Simpelius N, at a latitude of about 70° south on 7 September 2019. The wheeled Pragyan rover will move on the lunar surface and will perform on-site chemical analysis for a period of 14 days (one lunar day). It can relay data to Earth through the Chandrayaan-2 orbiter and lander, which will fly on the same launch. The orbiter will perform its mission for one year in a circularized lunar polar orbit of 100 × 100 km.[21][22][23] Launch of Chandrayaan-2 was originally scheduled for 14 July 2019 at 21:21 UTC (15 July 2019 2:51 IST) but was called off due to a technical snag noticed while filling the cryogenic engine of the rocket with helium[24] at around one hour before launch. The launch countdown for launch was freezed at T minus 56 minutes (56 minutes and 24 seconds[25] before launch).[26][7] It was launched on 22 July 2019 14:43 IST (09:13 UTC) from the Satish Dhawan Space Centre at Sriharikota in Nellore district of Andhra Pradesh.
