New Delhi . As India holds its breath for the historic soft landing of Chandrayaan-2 on Moon tonight, top scientists at ISRO will be closely monitoring the ‘most terrifying’ 15 minutes of the final phase of the lunar mission tonight.

Travelling at the speed of 6 km per second, Chandrayaan-2 will begin its final descent on Moon sometime between 1:30 am and 2:30 am tonight.

Prime Minister Narendra Modi along with 70 students selected from schools across the country will also watch the epic touchdown at the Bengaluru-based headquarters of the Indian Space Research Organisation headquarters during post-midnight hours on Saturday.
