the Chandrayaan-2 mission on July 22, 2019. The mission will send an orbiter, lander and rover to explore the moon's south pole. Chandrayaan-2's Vikram lander is expected to land around Sept. 6. Read our full wrap story: India Launches Ambitious Mission to Land at the Moon's South Pole
Chandrayaan-2 is India's planned second mission to the moon, which is expected to launch in 2019. It is a follow-up mission from the Chandrayaan-1 mission that assisted in confirming the presence of water/hydroxyl on the moon in 2009. Chandrayaan-2 will launch from the Satish Dhawan Space Center in Sriharikota, India, aboard a Geosynchronous Satellite Launch Vehicle (GSLV) rocket.
According to the Indian Space Research Organization (ISRO), the new mission will consist of an orbiter, a lander and a rover. The orbiter will perform mapping from an altitude of 100 kilometers (62 miles), while the lander will make a soft landing on the surface and send out the rover.
Development and science
Initially, ISRO planned to partner with Russia to perform Chandrayaan-2. The two agencies signed an agreement in 2007 to launch the orbiter and lander in 2013. Russia later pulled out of the agreement, however, according to a news report from The Hindu. The Russian lander's construction was delayed after the December 2011 failure of Roscosmos' Phobos-Grunt mission to the Martian moon of Phobos, the report stated.
Russia subsequently pulled out of Chandrayaan-2 altogether, citing financial issues. Some reports stated that NASA and the European Space Agency were interested in participating, but ISRO proceeded with the mission on its own.
The Chandrayaan-2 orbiter will circle the moon and provide information about its surface, ISRO stated. "The payloads will collect scientific information on lunar topography, mineralogy, elemental abundance, lunar exosphere and signatures of hydroxyl and water-ice," ISRO said on its website. The mission will also send a small, 20-kilogram (44 lbs.), six-wheeled rover to the surface; the rover will move semi-autonomously, examining the lunar regolith's composition.
hope it helps u mark me brainliest one plz
Answer:
Chandrayaan-2 mission is a highly complex mission, which represents a significant technological leap compared to the previous missions of ISRO. It comprised an Orbiter, Lander and Rover to explore the unexplored South Pole of the Moon. The mission is designed to expand the lunar scientific knowledge through detailed study of topography, seismography, mineral identification and distribution, surface chemical composition, thermo-physical characteristics of top soil and composition of the tenuous lunar atmosphere, leading to a new understanding of the origin and evolution of the Moon.

On August 20, 2019, Chandrayaan-2 was successfully inserted into lunar orbit. While orbiting the moon in a 100 km lunar polar orbit, on September 02, 2019, Vikram Lander was separated from the Orbiter in preparation for landing. Subsequently, two de-orbit maneuvers were performed on Vikram Lander so as to change its orbit and begin circling the moon in a 100 km x 35 km orbit. Vikram Lander descent was as planned and normal performance was observed upto an altitude of 2.1 km. Subsequently communication from lander to the ground stations was lost.

Subsequently communication from lander to the ground stations was lost.The Orbiter placed in its intended orbit around the Moon will enrich our understanding of the moon’s evolution and mapping of the minerals and water molecules in Polar regions, using its eight state-of-the-art scientific instruments. The Orbiter camera is the highest resolution camera (0.3 m) in any lunar mission so far and will provide high resolution images which will be immensely useful to the global scientific community. The precise launch and mission management has ensured a long life of almost seven years instead of the planned one year.
