ISRO's Chandrayaan-2 timeline : India gets ready for the historic event, reaching to the closest of planetoid

New Delhi, September 06: Ahead of the ISRO's mission on moon's south polar region, a place which remains unexplored till now, the Lander Vikram is scheduled to touch down on the moon surface between 1:30 am to 2:30 am.
