The mission will utilize the GSLV Mark 3 rocket, carrying the moon lander Vikram, and is expected to reach the moon's surface on August 23.
The mission includes a lander, propulsion module, and rover, focusing on developing new inter-planetary technologies.
Lessons learned from the previous mission have led to improvements in the design and software, reducing the number of engines on the lander and conducting rigorous testing.
Chandrayaan-3 will target the moon's South Pole, where water molecules were discovered during India's first moon mission in 2008. The lander will release the rover Pragyan to conduct scientific experiments and analyse the lunar soil.
