Its integrated module, which comprises technology and software developed across the country, includes ISRO's most powerful launch vehicle to date and a wholly-indigenous rover.Some of the advancements on the spacecraft include a lander capable of 'soft landing' on the lunar surface, an algorithm wholly-developed by India's scientific community and a rover capable of conducting in-situ payload experiments.The lander of Chandrayaan-2 is named 'Vikram' after Vikram A. Sarabhai, the father of the Indian Space Programme. It is designed to function for one lunar day, which is equivalent to about 14 Earth days. Vikram has the capability to communicate with IDSN at Byalalu near Bengaluru, as well as with the orbiter and the rover. The lander is designed to execute a soft landing on the lunar surface.Chandrayaan-2's rover is a six-wheeled robotic vehicle named 'Pragyan', which translates to 'wisdom'. It can travel up to 500 metre and leverages solar energy for its functioning. It can only communicate with the lander.The Chandrayaan-2 orbiter will be capable of communicating with Indian Deep Space Network (IDSN) at Byalalu as well as the Vikram lander. The mission life of the orbiter is one year and it will be placed in a 100x100 km lunar polar orbit.The rocket Geosynchronous Satellite Launch Vehicle-Mark III (GSLV Mk-III), carrying Chandrayaan-2, is India's most powerful launcher to date.It is capable of launching four-tonne class of satellites to the Geosynchronous Transfer Orbit (GTO), according to the Indian Space Research Organisation (ISRO).On entering the Moon's sphere of influence, on-board thrusters will slow down the spacecraft for lunar capture.The orbit of Chandrayaan-2 around the Moon will be circularised to 100x100 km orbit through a series of orbital manoeuvres.On the day of landing, the lander will separate from the orbiter and then perform a series of complex manoeuvres comprising rough braking and fine braking. Imaging of the landing site region prior to landing will be done for finding safe and hazard-free zones.After the lander Vikram finally lands near the South Pole, the rover will roll out and carry out experiments on the lunar surface for a period of 1 lunar day. The orbiter will continue its mission for one year.Chandrayaan-2, India's most ambitious second lunar mission, will shed light on a completely unexplored section of the Moon its South Polar region.Leveraging nearly a decade of scientific research and engineering development, the mission is aimed at helping in better understanding of the origin and evolution of the Moon by conducting detailed topographical studies, comprehensive mineralogical analyses and a host of other experiments on the lunar surface.It will explore the topography of the Moon and its composition and will search for water besides conducting in-situ studies.The lunar South Pole is especially interesting because of the lunar surface area there, which remains in shadow, and is much larger than the North Pole, according to ISRO.There is a possibility of the presence of water in the permanently shadowed areas around it. In addition, the South Pole region has craters that are cold traps and contain a fossil record of the early solar system, it said.What makes Chandrayaan-2 special is that it is the first space mission to conduct a soft landing on the Moon's South Polar region. It is also the first Indian expedition to attempt soft landing on the lunar surface with home-grown technology.Other specialities of the mission are that it will be the first to explore the lunar terrain with home-grown technology and India will be only the fourth country ever to carry out a soft landing on the lunar surface.( With inputs from IANS )
