Preparation for Chandrayaan-2 launch enters last lap

The preparation for the launch of ISRO’s Chandrayaan-2 is entering the penultimate stages with the  completion of the process of filling the liquid oxygen into the cryogenic stage. The process of filling the liquid hydrogen has already begun. According to ISRO, liquid hydrogen is currently being filled into the cryogenic stage of the GSLV Mk-III.

The second Mission mission will be launched at 2.43pm from Sriharikota in Andhra Pradesh. Although the original launch date was July 22, it had to be postponed due to technical snag  observed just 56 minutes before liftoff. There was a drop in pressure in the fuel tank and as a measure of abundant precaution, the Chandrayaan 2 launch was called off.

ISRO officials claimed that all glitches have been rectified. It will liftoff aboard the Geosynchronous Satellite Launch Vehicle Mark-III M1 (GSLV MkIII M1) rocket today from the Satish Dhawan Space Centre in Sriharikota.

Chandrayaan-2 is a follow-up mission to Chandrayaan 1, which helped confirm the presence of water/hydroxyl on the Moon in 2009. The mission consists of an orbiter, a lander called Vikram and a rover called Pragyan. While the orbiter is tasked with mapping the lunar surface from an altitude of 100 kilometres, the Vikram lander will make a soft-landing on the surface and release the Pragyan rover on 7 September 2019, according to ISRO. The mission will go to a previously unexplored region just 650 kilometres from the lunar South Pole. This will be the first time any mission has touched down so far away from the equator.

ISRO officials said that the countdown for the launch of Rs 978-crore mission had started at 6.43 pm on Sunday.
