The lander of India’s moon mission i.e. Chandrayaan-3 will land on the moon on August 23 at its scheduled time i.e. at 6:04 pm. On Tuesday (August 22), ISRO while giving information about the mission said that all the systems are being checked from time to time. All these are working properly.

Along with this, ISRO has shared new pictures of the moon, which were clicked by Chandrayaan-3. Chandrayaan captured these images with the help of the Lander Position Detection Camera (LPDC) from a distance of 70 km. Chandrayaan-3 is currently searching for the exact spot for landing on the Moon. It will be landed from a height of 25 km.
Two updates related to Chandrayaan-3:
Leaders of Hindu organizations in Karnataka’s Bagalkot district have filed a case against actor Prakash Raj for posting a joke on Chandrayaan-3 and have demanded action against him.
For the success of the mission, Havan is being performed at various places in the country. These include Kamakhya Temple in Varanasi, Uttar Pradesh, Sri Math Baghambari Gaddi, and Chamundeshwari Shiva Temple in Mumbai, Maharashtra.
The last 15 minutes of landing will be the most difficult:
Soft landing of Chandrayaan-3 lander will take 15 to 17 minutes. This duration is being called ’15 minutes of terror’ i.e. ’15 minutes of fear’. If India’s Chandrayaan-3 mission is successful, it will become the first country to land on the South Pole of the Moon.
Two hours before landing on the moon, the lander will decide whether it is appropriate to land at that time based on the position of the module and the conditions on the moon. The landing will be done on August 27 if any factor is not up to par.
Chandrayaan’s second and final deboosting operation was completed at 1:50 p.m. on Sunday night. After this, the minimum distance of the lander from the moon is 25 km and the maximum distance is 134 km. Deboosting slows down the speed of the spacecraft.
Contact established between the orbiter of Chandrayaan-2 and the lander of Chandrayaan-3:
The Indian Space Research Organization (ISRO) said on Monday that it has established contact between the orbiter of the Chandrayaan-2 mission and the lander of Chandrayaan-3. After the two-way communication was established, the orbiter said to the lander – ‘Swagat hai dost!’
ISRO shared pictures of the far side of the moon:
ISRO has shared pictures of the far side of the moon, that is, an area that is never visible from Earth. It was captured on 19 August 2023 by the Lander Hazard Detection and Avoidance Camera (LHDAC) on board Chandrayaan-3. This camera will help the lander to locate a safe landing area. That is, an area where there are no big stones and pits.
Pragyan Rover will leave the impression of Ashok Pillar on the moon:
The Project Director of Chandrayaan-1 and Chandrayaan-2 Mission was M. According to Annadurai, it will take 15 to 20 minutes for the Chandrayaan-3 lander to reach the surface of the moon from an altitude of 25 km on the evening of August 23. This is the most critical time.
After this, the six-wheeled Pragyan rover will come out from the Vikram lander through a ramp and will move on the lunar surface as soon as it receives the command from ISRO. During this time, its wheels will leave an imprint of India’s national symbol Ashoka Pillar and ISRO’s logo on the lunar soil.
Even if all else fails, Vikram will land:
ISRO Chairman S Somnath had said on August 9 about Vikram’s landing – ‘If everything fails, if all sensors fail, nothing works, still it (Vikram) will land, provided Algorithm work properly. We have also ensured that if two of Vikram’s engines fail this time, it will still be able to land.’
Now understand what is 15 minutes of terror:
Moon is 3,83,400 km away from our Earth. According to scientists, the last 15 minutes of Chandrayaan’s landing are going to be very important. These last moments are called 15 minutes of terror.
Actually, the last moments of space are called the Last Minutes Of Terror.
In these last minutes, the landing rover lands on the surface of the planet. In these 15 minutes, the lander works by itself. During this time no command can be given from ISRO. So this time is going to be very important. During this time, the lander has to land at the right time, at the right height, and using the right amount of fuel.
