Chandrayaan-3 highlights: The Indian Space Research Organisation (ISRO) is embarking to achieve a successful soft landing on the Moon with the launch of Chandrayaan-3. The spacecraft is now primed for its scheduled moon landing on August 23. This endeavor places India on track to become the fourth nation globally to achieve this remarkable milestone, joining the company of the United States, Russia, and China.

The mission was launched effectively on July 14 via the GSLV Mark 3 (LVM 3) heavy-lift launch vehicle from the Satish Dhawan Space Centre in Andhra Pradesh's Sriharikota. It is poised to touch down on the moon's exterior come August 23. It represents India's third lunar expedition and its second endeavor to achieve a delicate landing on the Moon's terrain.

Chandrayaan 3 highlights: In the last 30 km distance, what will happen?

Former ISRO scientist Mylswamy Annadurai explained that once the lander module's deboosting process is on Friday, the Chandrayaan-3 spacecraft will prepare itself for the soft landing on the Moon.

ISRO Chairman had said earlier that the most critical part of the landing is the process of bringing the velocity of the lander from 30 km height to the final landing and the ability to transfer the spacecraft from horizontal to vertical direction.

Chandrayaan 3: Why Moon's south pole is significant?

Chandrayaan 3: The polar regions of the Moon are very different terrain due to the environment and the difficulties they present and therefore have remained unexplored. All the previous spacecraft to have reached the moon landed in the equatorial region, a few degrees latitude north or south of the lunar equator.

Through this mission, scientists will explore the possibility of the presence of water in permanently shadowed areas around it.

Vikram has to take its own course of action: Former ISRO scientist, Mylswamy Annadurai

"Now Vikram has to take its own course of action. Further, it has to separate. So even after separating, then the major event comes. A major event is the 4800 Newton thrusters. They have to fire to take it to the lower orbit. That will also be done in two steps and ensuring that all the systems are working properly these two steps will go down, put a 100-kilometre orbit. Then from 100 go to the 30-kilometer orbit... that's very very vital. But when it's going very closer, closer to the Earth," Mylswamy Annadurai said while speaking to ANI.
