Chandrayaan-3: Indian Space Research Organization will launch Chandrayaan-3 today, July 14. ISRO will launch it from the Satish Dhawan Space Center in Sriharikota. Chandrayaan-3 will be launched at 2.35 pm. The Indian Space Research Organization will land it on the Moon's South Pole. Let us know why it is being made to land on the south pole of the moon and what is soft landing.Before this, ISRO had launched two more moon missions Chandrayaan-1 and Chandrayaan-2. ISRO launched Chandrayaan-1 on 22 October 2008. This was India's first successful lunar mission, but a few days later the Moon Impact Probe crashed near the Moon's South Pole, rendering it unable to complete its mission. After this, Chandrayaan-2 was launched on 22 July 2019, but Vikram Lander got damaged after reaching near the lunar surface, due to which it also failed.Mission will work equal to our 14 days and one day of the moonLander Vikram and Rover Pragyan will perform their work and tests on the lunar surface in a day equivalent to 14 Earth days. It is noteworthy that this time will be equal to one day of the moon. Former ISRO director K Sivan said that the success of Chandrayaan-3 will encourage India's next major mission Gaganyaan. During his tenure, the Chandrayaan-2 mission was sent in 2019, in which the lander was not successful in landing on the moon. He said that ISRO has reworked and rectified the factors that led to this failure. This time you will definitely get success. Sivan said that while Chandrayaan-3 faces the same challenges as previous missions, many things remain unknown in space. But by learning from mistakes, we have gained new confidence. It is expected that the success achieved this time will prove beneficial for future generations. The experiments conducted in the mission will increase scientific knowledge about not only the surface of the Moon, but also about the origin of the Earth.India can become the first country to land on the South PoleChandrayaan-3, India's third mission to the Moon, will be launched from the Satish Dhawan Space Center in Sriharikota at 2:35:17 pm on Friday. For this, the countdown of 25.30 hours started from 1:05 pm on Thursday. The Indian Space Research Organization (ISRO) will land the lander on the south pole of the Moon through Chandrayaan-3. If successful, India will become the first country to land a lander on the South Pole and the fourth country to land a vehicle on the Moon. So far only Russia, America and China have been able to land on the moon.Chandrayaan-3 will be launched from the rocket LVM-3M4 (formerly known as - GSLV Mark 3), made for carrying heavy satellites in space. About a month later, on August 23 or 24, a soft landing (safe landing on the surface with full control) of the lander Vikram will be done on the south pole of the Moon. This part of the Moon is still hidden from human eyes.Why is the mission landing on the South Pole only?So far no country has launched its lunar mission on the South Pole. According to scientists, the Moon's South Pole remains in more shadow than the North Pole and the possibility of water has also been found at the South Pole. The temperature here also remains cool. At the same time, scientists consider many possibilities on the South Pole in the future, as well as there is a possibility of the presence of water in its shadow areas. That's why Chandrayaan-3 will be made to land on the south pole of the moon.What is soft landing?According to experts, the force of gravity on the moon is 1/6 less than that of the earth. Due to this the speed of falling increases there. That's why the speed of Vikram Lander is gradually reduced and it is landed on the moon. When the Vikram lander remains at a height of 35 km from the moon, the 5 engines fitted in it are started and due to this the pressure starts to build up in the opposite direction of the lander. Because of this, gradually its speed becomes zero and it easily lands on a flat place. Which is called soft landing of a space mission.
