Answer:
Chandrayaan 2
Chandrayaan 2 is yet another endeavor of ISRO into the deep space that reflects its growing expertise and prowess in the realm of space research. First time ever, ISRO is going to land any of its space vehicle on the surface of the moon. Chandrayaan 2 will be launched on 15 July 2019 at 2.51 am IST from Sriharikota. It is expected it will reach its destination on 6 September 2019.
The mission Chandrayaan 2 comprises four components: the launcher, GSLV MKIII, lunar orbiter, Space Cadet the lander, Vikram, and Pragyan, the rover. GSLV MKIII is the heaviest rocket built by ISRO and it will take Space Cadet, Vikram, and Pragyan to the moon. Space Cadet will orbit moon for a year doing research and relay the rover’s data to ISRO Center. Vikram will assist Pragyan land on the surface of the moon using soft landing. Pragyan will travel using six wheels at the speed of one centimeter per second. It will use solar energy to power it.
The lander and the rover will conduct various experiments for approximately 15 days. ISRO will try to find whether there is permanent water on the shadowed part of the moon.
Besides the main payloads, the rocket will also be carrying 13 indigenous payloads and a Laser Retroreflector Array from NASA which will stay on moon two years longer than Chandrayan 2.
The total cost of the mission is Rs 603 crores, not including the rocket. We wish Chandrayan 2 all the best with prayers for its successful landing and completing the mission.
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.
