India’s Chandrayaan-2 mission has been completed for a year. This mission was not only like making a dream come true but also expected more than 130 crore people. On 22 July 2019, when the rocket GSLV called Mahabali of India flew with it, this flight was also a flight of expectations of every person in the country. It was successfully launched from Sriharikota range at 2:43 PM Indian time.
Chandrayaan-2’s lander Vikram and Rover Pragyan were on this rocket. GSLV was supposed to be launched on 15 July but due to technical glitch, its launch was postponed. It was to land on the lunar surface late on the night of 7 September. Everyone was waiting for the day when they would make a soft landing on the moon.
On September 7, everything was happening in a phased manner. Separating from the orbiter, the vehicle was rapidly approaching the lunar surface. The mission control room echoed with thunderous applause in the joy of getting pictures from it.
Chandrayaan-2 Vikram Lander and Pragyan Roverko were to land at about 70 ° south latitude in the ground between two craters of the moon – Manjinus C and Simpelius N. It was two o’clock in the night and it was just two km away from the lunar surface when suddenly its contact broke with the mission control room.
At the time when this happened, many other dignitaries including the Prime Minister of India, Narendra Modi were present there. Apart from this, some school children who were witnessing this historic moment were also there. In the mission control room, a streak was seen on the screen, indicating that the vehicle had lost its way.
Scientists kept trying to get in touch with it for a long time, but could not succeed. After some time, it has been said from ISRO that the landing of this vehicle took a hard landing on the lunar surface, due to which it was damaged and could not be detected.
For every Indian, this moment was like the breaking of a dream, but everyone saluted the emblem of the scientists of their country. Not only the people of India but the scientists and the space agency from all over the world appreciated this work done by India. Everyone said that this mission has not ended with failure, but has gained much from it. There were some special reasons for the world to say so.
In fact, the space agency of India undertook to make Chandrayaan-2 a soft landing on the moon south polar region. It was also India’s first mission of this kind. Second, it was based entirely on indigenous technology. India was the fourth country in the world to undertake a soft landing on the moon.
ISRO’s chairman, Dr. K Sivan, has announced that the lander has been viewed on the lunar surface with the help of a thermal image of the orbiter, adding that the orbiter and other agency is trying to establish soft communication with the lander. However, Chandrayaan-2 orbiter has taken some of the best images of the lunar surface with its high-resolution camera. Let us tell you that the place where India tried to send its vehicle on the moon is always in darkness.
No country had reached here before. Its purpose is to gather information there and make such discoveries that will benefit India as well as the entire humanity. It was also on these trials and experiences that major changes were needed to be made in the preparation of future lunar missions to help decide the new technology to be adopted in the upcoming lunar missions.
This mission could provide incredible information about the gradual development of the Earth and the environment of the Solar System. Also, it could be helpful to study the origin of the moon and the changes in its structure. As far as water on the moon is concerned, Chandrayaan-1 of India had made this discovery before this mission, which was also believed by the world later.
The Chandrayaan-2 mission was to find out how much of the moon’s surface and subsurface has water. This part of the moon was also special because cold craters (pits) in the southern polar region of the moon contain missing fossil records of the early solar system.
The two parts of the Chandrayaan-2 mission were very special. The first of these was the orbiter who would orbit the moon at an altitude of 100 km and gather other information, and the second was Vikram, who would search on the moon’s surface. It was also the responsibility of sending a high-resolution picture of the landing site before the lander’s separation from the orbiter. This orbiter was to work for a year. The lander was named after Dr. Vikram A. Sarabhai, the father of the Indian space program.
Let us tell you that one day of the moon is equal to 14 days of the earth.
