India heads to the moon on a robotic mission like never before. ISRO calls it the most complex mission ever to be undertaken by the Indian space agency. India's most powerful rocket, the Geosynchronous Satellite Launch Vehicle Mark-3, will lift off from Sriharikota on a three-in-one mission, carrying an orbitter, a lander named Vikram and a rover called Pragyaan, in an effort to unravel the several mysteries of the moon and put India's flag to the moon surface. NDTV's Science Editor uses an ISRO animation to explain the complexities of the mission. (Video courtesy: ISRO)
