ISRO's Chandrayaan-2 timeline: A look at India's historic moon mission

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:

Chandrayaan-2 spacecraft to finally touch down on the south polar region of moon.

The Chandrayaan-2 spacecraft will be the first-ever expedition to the south pole of the moon and the mission will make India the fourth country after the US, Russia, and China to conduct a soft landing on the lunar surface.

Prime Minister Narendra Modi will be present in Bengaluru to witness the historic moment live. About 60-70 school students will also join PM Modi.

The landing of Vikram lander will be followed by the Pragyan Rover roll out, from inside it, between 5.30 am to 6.30 am. 

ISRO chairman Dr K Sivan is also scheduled to address a press conference between 8.00 am to 9.00 am on September 7.
