"All preparatory work for Chandrayaan-2 launch has been completed. Technical snags that developed in the first attempt have been rectified. Today evening, the countdown for the launch will begin. Chandrayaan-2 will perform 15 crucial manoeuvres in days to come," Indian Space Research Organisation (ISRO) Chief K Sivan had said earlier on Sunday.
Earlier on Saturday, the ISRO successfully completed the launch rehearsal of the Chandrayaan-2 mission.
"Launch rehearsal of #GSLVMkIII-M1 / #Chandrayaan2 mission completed, performance normal #ISRO," ISRO said in a tweet.
During the countdown, the rocket and spacecraft's systems will undergo checks and fuel will be filled to power the rocket engines.
This is the second attempt to launch the Chandrayaan-2 spacecraft onboard the Geosynchronous Satellite Launch Vehicle - Mark III (GSLV Mk III). It was earlier scheduled to take off on July 15 but was postponed due to a technical snag one hour prior to the rocket lift-off.

Chandrayaan 2, the most ambitious lunar mission of the country, will explore the parts of Moon which have never been explored in the past - the south polar region. According to eminent space scientists, Chandrayaan 2 is a mission which has been described as one of the most complex ever undertaken by ISRO.
The main objective of the latest Moon mission is to carry out various experiments to understand the extent and significance of the presence of water on the celestial body as confirmed by the Chandrayaan 1 mission. This is also for the first time that India is trying to land a robotic rover on Moon.
According to ISRO Chairman Kailasavadivoo Sivan, the landing site, at a latitude of about 70 degrees south, is the southernmost for any mission till date. The spacecraft consists of an orbiter, a lander, and a rover together referred to as "composite body".
It will be the first Indian expedition to attempt a soft landing on the lunar surface. This mission will make India the fourth country after the US, Russia, and China to carry out a soft landing on Moon.
