GSLV-F10/Chandrayaan-2 Mission is planned during the first-half of 2018, according to reports. The 3,290 kg Chndrayaan-2 will orbit around the moon and study its lunar conditions to collect data on its topography, mineralogy, exosphere and the "presence" of water ice and hydroxyl.
On reaching the 100 km lunar orbit, the lander with the six-wheeled rover will separate from the spacecraft and descend slowly to soft land on the lunar surface at a designated spot.
"The rover will move around the landing site in semi-autonomous mode as per the ground commands while its instruments will observe the lunar surface and transmit the data for analysis of its soil," says an official.
Chandrayaan-2, India's second mission to the moon is a totally indigenous mission comprising of an Orbiter, Lander and Rover. After reaching the 100 km lunar orbit, the Lander housing the Rover will separate from the Orbiter. After a controlled descent, the Lander will soft land on the lunar surface at a specified site and deploy a Rover.
The mission will carry a six-wheeled Rover which will move around the landing site in semi-autonomous mode as decided by the ground commands. The instruments on the rover will observe the lunar surface and send back data, which will be useful for analysis of the lunar soil. The Chandrayaan-2 weighing around 3290 kg and would orbit around the moon and perform the objectives of remote sensing the moon.
The payloads will collect scientific information on lunar topography, mineralogy, elemental abundance, lunar exosphere and signatures of hydroxyl and water-ice, according to Isro.
Chandrayaan-1 was launched by Isro in October 2008, and operated until August 2009. The mission included a lunar orbiter and an impactor. India launched the spacecraft using a PSLV-XL rocket, serial number C11, The remote sensing lunar satellite had a mass of 1,380 kg (3,040 lb) at launch and 675 kg (1,488 lb) in lunar orbit. Over a two-year period, it surveyed the lunar surface to produce a complete map of its chemical characteristics and three-dimensional topography.
Chandrayaan stopped sending radio signals about 20:00 UTC on 28 August 2009, shortly after which the ISRO officially declared the mission over. On 2 July 2016, NASA used ground-based radar systems to relocate Chandrayaan-1 in its lunar orbit, more than seven years after it shut down, according to Wikipedia.
