Roscosmos later withdrew in wake of the failure of the Fobos-Grunt mission to Mars, since the technical aspects connected with the Fobos-Grunt mission were also used in the lunar projects, which needed to be reviewed.On 19 June 2018, after the program's fourth Comprehensive Technical Review meeting, a number of changes in configuration and landing sequence were planned for implementation, pushing the launch to the first half of 2019.In addition, this area is also supposed to have ancient rocks and craters that can offer indications of history of the Moon.
The impact of a sub-satellite (Moon Impact Probe – MIP) on the surface on the Moon will also be studied as a fore-runner to future soft-landing missions.
It is hoped that the mission will provide new insights in understanding the Moon’s origin and evolution.
The unexplored territory gives an opportunity for the Mission to discover something new.
The South Pole of the Moon holds possibility of presence of water.
at a latitude of about 70° south on 6 September 2019.
The wheeled Pragyan rover would've moved on the lunar surface and would've performed on-site chemical analysis for 14 days (one lunar day).Several templates and tools are available to assist in formatting.(One such tool to fix up some types of bare URLs is re Fill, see also its documentation) The mission was launched to the Moon from the second launch pad at Satish Dhawan Space Centre on 22 July 2019 at PM IST ( UTC) by a Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk III) but failed to land to the lunar surface on 6 September 2019 at about AM IST ( PM UTC) due to a loss of contact with the spacecraft at 2.1 kilometers from the moon's surface.The primary objectives of Chandrayaan-2 are to demonstrate the ability to soft-land on the lunar surface and operate a robotic rover on the surface.Scientific goals include studies of lunar topography, mineralogy, elemental abundance, the lunar exosphere, and signatures of hydroxyl and water ice.There is a possibility of the presence of water in permanently shadowed areas around it, the agency said, adding craters in the south pole region have cold traps and contain fossil records of the early solar system.Challenges involved in the moon landing are identifying trajectory accurately; taking up deep space communication; trans-lunar injection, orbiting around the moon, taking up soft landing on the moon surface, and facing extreme temperatures and vacuum.It could relay data to Earth through the Chandrayaan-2 orbiter and lander, which were launched together on the same rocket.The orbiter would perform its mission for one year in a circularized lunar polar orbit of 100 × 100 km.Besides this, chemical and mineralogical mapping of the entire lunar surface will be undertaken.Some of the chemical elements to be mapped are Magnesium, Aluminum, Silicon, Calcium, Iron, Titanium, Radon, Uranium, & Thorium.
