First photograph of earth, sent by Chandrayan 2 ….. What an eye-catchin visual it is

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 were launched together on the same rocket. 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] about one hour before launch. The countdown was frozen at T minus 56 minutes, 24 seconds (56 minutes and 24 seconds[25] to 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.

A successful landing would make India the fourth country to achieve a soft landing on the Moon, after the space agencies of the USSR, US and China.[27] If successful, Chandrayaan-2 will be the southernmost lunar landing, aiming to land at 67°S or 70°S latitude.[28][29][30][31]
