Chandrayaan-2 is India's second lunar exploration mission after Chandrayaan-1. Developed by the Indian Space Research Organisation (ISRO), the mission is planned to be launched to the Moon by a Geosynchronous Satellite Launch Vehicle (GSLV Mk II).
It includes a lunar orbiter, lander and rover, all developed by India. The ISRO is planning to launch Chandrayaan-2 in the first quarter of 2018. According to ISRO, this mission will use and test various new technologies and conduct new experiments. The wheeled rover will move on the lunar surface and will perform on-site chemical analysis. The data will be relayed to Earth through the Chandrayaan-2 orbiter.
The mission is planned to fly on a Geosynchronous Satellite Launch Vehicle (GSLV Mk II) with an approximate lift-off mass of 3,250 kg from Satish Dhawan Space Centre on Sriharikota Island. As of December 2015, the mission has an allocated cost of ₹603 crore.
The orbiter will orbit the Moon at an altitude of 100 km (62 mi). The mission would carry five instruments on the orbiter. Three of them are new, while two others are improved versions of those flown on Chandrayaan-1. The approximate launch mass will be 1,400 kg (3,100 lb).
The Orbiter High Resolution Camera (OHRC) will conduct high-resolution observations of the landing site prior to separation of the lander from the orbiter. Interfaces between the orbiter and its GSLV Mk II launch vehicle have been finalised.
Unlike Chandrayaan-1's Moon Impact Probe, which impacted the Moon's surface, the lander will make a soft landing to then deploy the rover. The lander will not perform any scientific activities.
The approximate mass of the lander and rover is 1,250 kg (2,760 lb). Initially, the lander was slated to be developed by Russia in collaboration with India. When Russia stated its inability to provide the lander to meet even the revised time frame of 2015, Indian officials decided to develop the lander independently.
