Chandrayaan-2 mission faced challenges during its soft landing in 2019. The ‘Launch Rehearsal’ simulating the entire launch preparation and process has been concluded by the ISRO.  Scientists said that after the lift-off at 2.35 pm on Friday, around 16 minutes after lift-off, the propulsion module is expected to get separated from the rocket and would orbit the earth for about 5-6 times in an elliptical cycle with 170 km closest and 36,500 km farthest from earth moving towards the lunar orbit.

The propulsion module along with the lander, after gaining speed would proceed for an over a month-long journey towards reaching the orbit of the moon until it goes 100 km above the lunar surface. After reaching the desired position, the lander module would begin its descent for a soft landing on the south pole region of the moon and this action is expected to take place on August 23 or 24, scientists at ISRO said.

The moon's south pole region has been chosen because the Lunar South Pole remains much larger than that at the North pole. There could be a possibility of the presence of water in permanently shadowed areas around it.

"After the successful landing of Chandrayaan-3 on the surface of the Moon, the rover, which has six wheels, will come out and is expected to work for 14 days on the Moon. With the support of multiple cameras on the rover, we will be able to receive images," Union Minister of State (Independent Charge) for Science and Technology, Jitendra Singh mentioned earlier.

Chandrayaan-3 is a follow-on mission of Chandrayaan-2 and is aimed at demonstrating India's capability in soft landing and roving on the surface of the Moon or the Lunar surface. Chandrayaan-2, India's second mission to the moon, was launched on
