Answer 2

Option A - 1 Only

■ Explanation :-

• Statement 2 is incorrect :- Chandrayaan-2 will be the first mission to explore the Moon’s South Polar Region.

• Statement 3 is incorrect :- If successful, India will become only the fourth country to make a soft landing on the lunar surface, after the former Soviet Union, the US and China.

More Information

■ Chandrayaan-2 :-

• Chandrayaan-2 is a completely indigenous lunar mission to the Moon’s South Polar Region.

• It will be launched from the second launch pad at Satish Dhawan Space Centre, Sriharikota using GSLV Mk-III. If successful, India will become only the fourth country to make a soft landing on the lunar surface, after the former Soviet Union, the US and China.

• Chandrayaan 2 attempts to foster a new age of discovery, increase our understanding of space, stimulate the advantage of technology, promote global alliances and inspire a future generation of explorers and scientists.

• The mission will help us gain a better understanding of origin and evolution of the moon by conducting detailed topographic studies, comprehensive mineralogical analyses and a host of other experiments on the lunar surface.

• The objectives of the mission are :-

¤ Extensive mapping of the lunar surface to study variations in lunar surface composition which is essential to trace back the origin and evolution of earth

¤ Further studies on the extent of water molecule distribution (discovered by Chandrayaan-1) on/below the surface and in the tenuous lunar exosphere to address the origin of water on the moon

¤ Exploring the lunar South Pole because: (i) it remains in shadow and is much larger than the North Pole (ii) there is a possibility of the presence of water in the permanently shadowed areas around it (iii) it has craters that are cold traps and contain a fossil record of early solar system.

¤ The mission attempted to soft-land the lander - Vikram and rover – Pragyan in a high plain between two craters at an altitude of about 70°S

¤ Vikram Lander is named after Dr. Vikram Sarabhai and is designed to function for 1 lunar day (i.e. 14 earth days). It has the capability to communicate with Indian Deep Space Network (IDSN) near Bangalore as well as with the orbiter and rover.

¤ Pragyan (‘wisdom’ in Sanskrit) Rover is a 6-wheeled robotic vehicle that can communicate only with the lander and leverages solar energy for its functioning.
