New Delhi, 22 August: Regarding the landing of Chandrayaan-3, Dr. Surendra Pal, former advisor to the Indian Space Research Organisation (ISRO), said that Vikram Lander can withstand a rough landing. This time, ISRO has made complete preparations for the landing of Vikram Lander on the Moon. ISRO scientists are full of confidence this time on the basis of experience. Even if everything does not go according to plan on August 23, ISRO has also prepared a plan B to postpone the landing date until August 27.
Dr. Surendra Pal said that an area of 2 to 5 kilometres is being seen for landing on the moon. Since the south pole of the moon has large craters, some flat surfaces are being searched for landings. Vikram Lander’s legs are so strong that they can withstand some rough landings as well.
How will the speed of Chandrayaan be controlled?
Vikram Lander will begin its journey to land on the moon from an altitude of 25 km. It will take around 11.5 minutes to reach the next stage. That is, up to a height of 7.4 kilometers. Its speed will be 358 metres per second until it reaches an altitude of 7.4 kilometers. The next stop would be 6.8 kilometers. At an altitude of 6.8 kilometres, the speed will decrease to 336 metres per second. The next level will be 800 metres. At an altitude of 800 metres, the lander’s sensors will beam laser beams onto the lunar surface to find the right spot for landing. The speed of the lander at an altitude of 150 metres will be 60 metres per second. That is, between the heights of 800 and 150 meters. The speed of the lander at an altitude of 60 metres will be 40 metres per second. That is, between the heights of 150 and 60 meters. At a height of 10 metres, the speed of the lander will be 10 metres per second. While landing on the surface of the moon, i.e., for a soft landing, the speed of the lander will be 1.68 metres per second.
