New Delhi: India will script history on September 7 when its moon mission Chandrayaan-2 will land on moon's south polar region, a place which remains unexplored till now. The Lander Vikram is scheduled to touch down on the surface of the moon on September 7 between 1:30 am to 2:30 am. 

The spacecraft revolved around the earth's orbit for nearly 23 days and then began its journey to the moon on August 14.

Chandrayaan-2's landing on the south pole of the moon is a milestone India and for the world too and all eyes are on Indian Space Research Organisation (ISRO) today. 

As India is all set to script history, let's have a look at how the events unfolded:
