Chandrayaan-3 Landing: The moment for which the whole country and the world is waiting, that moment is going to come in the next few hours. Chandrayaan-3 is going to create history today by landing on the surface of the moon at 6.4 pm on Wednesday (August 23). After the failure of Mission Chandrayaan-2, ISRO launched this new Moon mission on 14 July.
According to the Hindustan Times, on August 5, Chandrayaan-3 entered the moon's orbit. On August 17, both the lander and rover modules separated. India is on its way to becoming the fourth country after the US, China and the erstwhile Soviet Union to make a soft landing on the lunar surface. Not only this, if the entire development continues according to ISRO, then India will become the first country to make a soft landing on the Moon's South Pole.
What is soft landing and hard landing?
Soft landing is the controlled landing of a spacecraft on the lunar surface. At the time of landing, the speed of the spacecraft will gradually decrease and will touch the surface at a speed of about 0. A hard landing is a crash landing where the spacecraft is destroyed upon hitting the surface. Earlier, Chandrayaan-2 failed during soft landing, but this time ISRO Chief S. Somnath claims that whatever happens, soft landing will happen.
Soft landing of Chandrayaan-3, what will happen today?
Spacecraft 30 km. 1.68 km from the height of Will start descending at the speed of hourly and by the time Chandrayaan-3 reaches the surface of the moon, its speed will be almost 0. Today's landing is also important because Chandrayaan-3 will turn from horizontal to vertical direction. Chandrayaan-2 had to face a problem at this place.
What will happen after the successful landing of Chandrayaan-3 on the moon?
The Rover (Pragyan) will take off from the Lander (Vikram) and land on the surface of the Moon. After this, the rover will analyze the lunar surface as well as study the current environment. Lander and Rover can remain safe for one lunar day i.e. one day on the moon. One lunar day is equal to 14 Earth days. No information has been shared by ISRO about what will happen after 14 days. However, scientists have not ruled out the possibility that the lander and rover can survive for more than one lunar day.
A lunar day is the time the Sun shines on the Moon. As long as the sun continues to shine, all the systems will continue to function properly. After this, when the sun sets on the moon, it will become dark there and the temperature will go up to minus 180 degree Celsius. In such a situation, the chances of survival of the spacecraft will decrease. If it survives then another achievement will be added to ISRO's account.
What will happen if Chandrayaan-3 does not make a successful landing?
According to ISRO Chief S Somnath, the possibility of this happening is very less. He has already said that there is no possibility of a mistake this time. Soft landing will happen even if all the engines and sensors of Vikram Lander stop working.
He had said, “If everything fails, if all sensors fail, nothing works, still he (Vikram) will land. It is designed like this. Provided the propulsion system should work properly. We have also made sure this time that even if both the engines (of Vikram) don't work this time, it will land."
Even after all these arrangements, if Chandrayaan-3 fails, then it will be tried again on August 24, and if it still does not work, then it can be tried again after 14 days i.e. on the next lunar day, when the sun will rise there. .
