Chennai, July 13 : The 20-hour countdown for the launch of the prestigious second lunar mission, Chandrayaan-2, will commence at the spaceport of Sriharikota on Sunday morning.
The countdown would start at 6.51 am on Sunday morning, according to ISRO Chairman Dr K Sivan. Stating that the launch preparations were progressing
smoothly, he said all the checks were being carried out and GSLV-Mk-III, India's heaviest rocket, would lift off from the Second Launch Pad at 2.51 am on Monday.
During the countdown, propellant filling operations would be carried in the 44 metre tall three-stage vehicle, which uses the cryogenic engine in the third
stage. This mission will help ISRO gain a better understanding of the origin and evolution of the Moon by conducting detailed topographical studies, comprehensive mineralogical analyses, and a host of other experiments on the lunar surface.
It would also explore discoveries made by Chandrayaan 1, such as the presence of water molecules on the Moon and new rock types with unique chemical composition. Through this mission, ISRO aims to expand India's footprint in space, inspire a future generation of scientists, engineers and explorers and surpass international aspirations. About 16 minutes after lift off, Chandrayaan-2 will be injected into an earth parking 170 x 40,400 km orbit. A series of maneuvers will be carried out to raise its orbit and put Chandrayaan-2 on Lunar Transfer Trajectory. (UNI)
