On July 15th, scientists from ISRO will attempt what no country in the world has managed to achieve- Landing at the Lunar South Pole. Chandrayaan 2 is India’s Lunar mission & is attempting to study Earth’s closest celestial object.
Objectives of Chandrayaan 2
- Extensive mapping of the lunar surface
- Study variants in the composition of the lunar surface
- Trace Moon’s origin & evolution
- Trace evidence of Water molecules and distribution of lunar surface
- Study permanently shadowed South Pole
- Study craters on South Pole (cold traps) as it contains ‘fossilised record of Solar System’
Where will the Solar Mission land?
Using the Vikram Lander & Pragyan Rover, Chandrayaan 2 will attempt a soft landing between two craters – Manzinus C & Simplelius N at a latitude of 70Â° south. India is the fourth country to attempt soft landing on lunar surface

Parts of the Lunar Mission
Launcher- GSLV Mk-III
India’s most powerful launcher until today and is completely indegenous.
The orbiter is the relay component between the rover & scientists on ground. It will also observe the lunar surface
Named after the father of Indian space program, Dr Vikram Sarabhai. The lander is designed to execute a soft landing & function for one lunar day (equal to 14 Earth days). Lander can communicate with ISDN in Bangalore, orbiter as well as the rover.
The 6 wheel robotic rover can travel upto 500m & works on solar energy. It can however only communicate with Lander
After its launch on July 15, the mission will land on Moon by September 6th. The scientific experiment will be held for 14 days & the expected period for orbital experiment is one year.
