चंद्रयान-3 पृथ्वी की कक्षा में पहुंचा: ISRO चीफ बोले- सफर शुरू हो गया, 23 अगस्त को शाम 5.47 बजे लैंडिंग होगी

The Indian Space Research Organization ie ISRO launched the Chandrayaan-3 mission on Friday afternoon at 2.35 pm. Chandrayaan was sent into space through an LVM3-M4 rocket from the Satish Dhawan Space Center in Sriharikota in Andhra Pradesh.

Chandrayaan successfully reached the Earth’s orbit after 16 minutes. ISRO Chief S Somnath said after the launch that the vehicle has started its journey towards the Moon. If everything goes according to plan, it will land on the moon on August 23 at 5.47 pm.

Chandrayaan-3 has Lander, Rover and Propulsion Module. The lander and rover will land on the Moon’s South Pole and conduct experiments there for 14 days. The propulsion module will study the radiation coming from the Earth by staying in the Moon’s orbit. Through the mission, ISRO will find out how earthquakes occur on the lunar surface. It will also study the lunar soil.

16 minutes after launch, the rocket left Chandrayaan-3 in the Earth’s orbit.

A large number of people were present in the ISRO gallery to watch the launch of Chandrayaan-3.

India will become the fourth country to do so
If there is success in soft landing i.e. the mission is successful, then after America, Russia and China, India will become the fourth country to do so. There were several spacecraft crashes before both the US and Russia successfully landed on the Moon. China is the only country to be successful in its first attempt with the Chang’e-3 mission in 2013.

After separating from the propulsion module, the lander will land on the lunar surface on August 23 in this way.

Chandrayaan-3 cheaper than the budget of Adipurush film
The budget of Chandrayaan-3 without launching cost is around Rs 615 crore, while the budget of the recent film Adipurush was Rs 700 crore. Means Chandrayaan-3 is about 85 crore rupees cheaper than the cost of this movie. The cost of Chandrayaan 2 sent 4 years before this was also Rs 603 crores. At the same time, 375 crore rupees were spent on its launching.

A new chapter in India’s space journey
After the successful launch of Chandrayaan-3, Prime Minister Narendra Modi described it as a new chapter in India’s space journey. He also said that this important achievement is a testimony to the tireless dedication of our scientists. I salute his spirit and talent!

Now answers to 4 important questions related to 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 do 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’ had shown 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.

Manish Purohit, ex-scientist of ISRO, said that through this mission, India wants to tell the world that it has the capability of soft landing on the moon and running the rover there.

2. Why is the mission being 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.

If all goes well, Chandrayaan-3 will 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.

There are many parts on the South Pole of the Moon where sunlight never reaches and the temperature goes below -200 degree Celsius.

3. Why 4 engines instead of 5 in the lander this time?
This time the lander has four engines (thrusters) fitted at the four corners, but last time the fifth engine in the middle has been removed. Final landing will be done with the help of two engines only, so that two engines can work in case of emergency. The fifth engine was added at the last moment in the Chandrayaan 2 mission. The engine has been removed so that more fuel can be carried along.

4. Why will the mission be for 14 days only?
Manish Purohit told that there is night for 14 days and light for 14 days on the moon. When it is night here, the temperature drops below -100 degree Celsius. Chandrayaan’s lander and rover will generate power from their solar panels. That’s why they will generate power for 14 days, but the power generation process will stop at night. If there is no power generation, the electronics will not be able to withstand the severe cold and will get damaged.
