Chandrayaan-2 Mission


From UPSC perspective, the following things are important :

Prelims level : Chandrayan 2

Mains level : Significance of the Mission

  • The Vikram lander of the Chandrayaan-2 failed to make a smooth soft-landing, unable to bring down its speed to the required level.
  • The Vikram lander and Pragyan rover were supposed to land on the moon and carry out observations and experiments for 14 days.

Why it was difficult?

  • The polar regions of the moon are a very different, and difficult, terrain.
  • Many parts lie in a completely dark region where sunlight never reaches, and temperatures can go below 230 degree Celsius.
  • Lack of sunlight and extreme low temperatures create difficulty in operation of instruments.
  • In addition, there are large craters all over the place, ranging from a few cm in size to those extending to several thousands of kilometres.
