As soon as the sun rose on the moon on the evening of 23 August, ISRO’s Chandrayaan created history by landing on its south pole. India has become the first country in the world to successfully land on the south pole of the Moon.
Chandrayaan-3 started the landing process on Wednesday evening at 5.44 pm. After this, in the next 20 minutes, it completed the journey of 25 km from the final orbit of the Moon. The lander of Chandrayaan-3 took the first step on the moon at 6:40 pm. It may take a day for the rover to come out.
ISRO told that all the sensors of Lander-Rover are being tested. If all goes well, the rover will be taken out after 3-4 hours by giving a command from ISRO. If things do not happen on a fixed scale, then the decision to take out the rover will be taken after 24 hours.
ISRO director S. Somnath said- The next 14 days are very important for us. It may also take a day for the Pragyan rover to come out. Pragyan will give us information about the atmosphere of the moon. We have many missions lined up. Soon Aditya L1 will be sent to Sun. Work on Gaganyaan is also going on.
After reaching the moon, Chandrayaan-3 sent a message – I have reached my destination. On the other hand, Prime Minister Modi congratulated the countrymen from South Africa and said- Now Chandamama is not far away. India is the fourth country to successfully land on the moon.
With this success, India has become the fourth country to land a mission on any part of the Moon. Earlier only America, Soviet Union and China could do this.
Last 20 minutes of landing were minutes of terror
The soft landing of Chandrayaan-3’s lander took 20 minutes. This duration was being called ’20 minutes of terror’ i.e. ’20 minutes of fear’. These minutes of terror started at 5.44 pm. Then the moon was 31 km away from the lander. Its vertical landing process started.

Now everyone is waiting for Pragyan Rover to come out from Vikram Lander. It will come out after the dust settles. After this Vikram and Pragyan will photograph each other and send it to Earth.
ISRO, the Indian Space Research Organization operating the Chandrayaan mission, launched Chandrayaan on 14 July from Sriharikota. On the 41st day, planning was done to land on the south pole of the moon.
PM Modi said – Chanda is not from maternal uncle, but from a tour
Prime Minister Narendra Modi congratulated the scientists by joining the video conferencing. He said- This moment is of India’s strength. This is the moment of new energy, new faith, new consciousness in India. It rained nectar in the time of immortality. We took a pledge on earth and made it come true on the moon. We have witnessed the new flight of new India in space. Then this record would have been in the name of Russia.
Before India, Russia was going to land Luna-25 on the south pole of the moon. This landing was to take place on August 21, but while changing the last orbit, it deviated from the path and crashed on the lunar surface.
It took 41 days to land on the moon
Chandrayaan-3 was launched from Sriharikota in Andhra Pradesh on July 14 at 3.35 am. It took 41 days to land on the lunar surface. The total distance of the Moon from the Earth is 3 lakh 84 thousand kilometers.
What will happen after landing?
Vikram will be on and will communicate after the dust settles.
Then the ramp will open and Pragyan Rover will come from the ramp to the lunar surface.
The wheels will leave an imprint of the Ashoka Pillar and the ISRO logo on the lunar surface.
Vikram Lander will take photo of Pragyan and Pragyan of Vikram. They will send this photo to the earth, the night of 50 scientists was cut in the eyes, there was an atmosphere of excitement and anxiety in the command center.
More than 50 scientists at the Mission Operation Complex (MOX) of ISRO’s Telemetry and Command Center (ISTRAC) in Bengaluru were busy checking the data received from Chandrayaan-3 on computers throughout the night. They kept sending inputs to the lander, so that every scope of taking wrong decisions at the time of landing was over.
At the time of landing on the moon, there was an atmosphere of excitement and restlessness in the ISRO center. Now the answers to 4 important questions related to the Chandrayaan mission…
1. What will India gain from this mission?
Manish Purohit, ex-scientist of ISRO, says that through this mission, India wants to tell the world that it has the ability to make a soft landing on the moon and run the rover there. This will increase the world’s trust in India which will help in increasing commercial business. India has launched Chandrayaan from its Heavy Lift Launch Vehicle LVM3-M4. India has already shown the capability of this vehicle to the world.
In the past, Amazon founder Jeff Bezos’ company ‘Blue Origin’ showed its interest in using ISRO’s LVM3 rocket. Blue Origin wants to use LVM3 for commercial and tourism purposes. Through LVM3, Blue Origin will take its crew capsule to the planned Low Earth Orbit (LEO) space station.
2. Why was the mission sent to the South Pole only?
The polar regions of the Moon are quite different from other regions. There are many parts here where the sunlight never reaches and the temperature goes down to -200 degree Celsius. In such a situation, scientists estimate that there may still be water present in the form of ice. India’s 2008 Chandrayaan-1 mission indicated the presence of water on the Moon’s surface.
The landing site of this mission is the same as that of Chandrayaan-2. Near the South Pole of the Moon at 70 degree latitude. But this time the area has been increased. The landing site in Chandrayaan-2 was 500 meters X 500 metres. Now, the landing site is 4 km X 2.5 km.
Chandrayaan-3 has become the world’s first spacecraft to soft-land near the Moon’s south pole. All previous spacecraft to land on the Moon have landed in the equatorial region, a few degrees of latitude north or south of the lunar equator.
3. Why 4 engines instead of 5 in the lander this time?
This time four engines (thrusters) were installed at the four corners of the lander. Last time the fifth engine in the middle of Chandrayaan-2 was removed
