Chandrayaan 3 or Moon Mission is the biggest mission by ISRO to explore Moon. India has launched Chandrayaan to identify water on the solar pole of Moon. Later, with Chandrayaan 2, ISRO aimed to further explore the surface. Along with South Pole of Moon to estimate the possiblities of existence of life and water supplies. NASA has assisted India in building complete indigenous equipment for Chandrayaan 2. The mission failed as lander collapsed into the surface of Moon while landing.
With Chandrayaan 3, ISRO is aiming to complete the objectives of Chandrayaan 2. Also, to better on it. ISRO has included a rover, a lander and a propulsion module. The mission will explore South Pole of Moon for water, basically ice molecules. Earth North Pole and South Pole contain huge ice caps and huge amount of ocean water. If Moon also consists of Ice molecules near South Pole, then it becomes more interesting to explore. Chandrayaan proved that ice molecules do exist near South Pole.

Major Moon Missions have landed near Equator of Moon and none at South Pole. As orbiters have indicated interesting terrain and many things to explore, ISRO has decided to do the improbable. Major countries have deemed it is unsafe to send spacecrafts like Chandrayaan to poles of Moon. Hence, ISRO has made Chandrayaan major objective to safely land near South Pole and explore the terrain. Chandrayaan 3 will launch into space on 14th July, at 14:30 hours IST. ISRO expects the rover to land on Moon near South Pole by August 23rd. Spacecraft will take a month to reach Moon.
