Chandrayaan 2 mission for ISRO is very important because in the first Chandrayaan mission the launch vehicle carries only an orbiter and the launch vehicle is also small which is PSLV(Polar Satellite Launch Vehicle).
But in Chandrayaan two there are also other things rather than an orbiter, it is a lander and a rover that lands on the moon's surface and also will take the information on the moon's atmosphere that there is life on the moon or not. The launch vehicle used for Chandrayaan 2 is GSLV(Geosynchronous Satellite Launch Vehicle) which is the heaviest launch vehicle ISRO has.
The first launch date of the Chandrayaan 2 mission is on 15 July 2019 but 15 minutes before launch there is some technical issue in the launch vehicle. So, the launch of the mission is postponed and the final date of the launch of Chandrayaan 2 is on 22 July 2019. And finally, it is launched on 22 July in Satish Dhawan Space Centre, Sriharikota by 3:00 pm.
Chandrayaan 2 mission is different from Chandrayaan 1
The first lunar mission of India is launched in 2008 when India was the country who have found water on the moon. In the first mission, there was only an orbiter who got placed in the outer place of the moon and it rotates around the moon to collect information. But in Chandrayaan 2 there are some types of equipment added to the launch vehicle. Along with an orbiter, there is a lander and inside the lander, there was a rover.
The mission of Chandrayaan 2 is that the lander and the rover would land in the south direction of the moon. It is also a very toughest thing to land these types of equipment in the south direction of the moon because those countries landed on the moon in the north direction. But India was the first country who will try to land its items on the southern part of the moon. No other country would try to land their satellite in the south direction of the moon.
Chandrayaan 2 wouldn’t reach its proper destiny
When ISRO launches Chandrayaan 2 on 22 July 2019, it takes 48 days to reach the moon's atmosphere. The orbiter was successfully stable in the moon's outer atmosphere and it work for 7 years to collect information about the moon and send it to ISRO. Prime Minister Narendra Modi also comes to ISRO headquarters to see the progress of the Chandrayaan 2 mission.
But the lander and rover could not successfully land on the moon's surface. When it was landing on the moon's surface just before seconds it could be lost its connection to ISRO.
Scientists are re communicating with the lander and rover but they can’t receive signals from the lander and rover. While ISRO is shocked that the lander and rover had not established on the moon but orbiter had stable properly to the moon’s surface and he been doing it's for the next 7 years.
PM Modi motivates ISRO and Hug ISRO Chairman
When Chandrayaan 2 is properly successful whole ISRO was feeling demotivated and ISRO chairman K Sivan was crying. PM Modi had give a speech at ISRO headquarter where he give thanks to ISRO scientist for their contribution to India’s space program. He also said that failure is an important part of our lives and we have to face the situations, and sometimes we got fail but we have never lost hope.
Because failure shows us the value of success and if we do hard work and remain become confident then one day we got success. When he leaves ISRO headquarters ISRO chairman Dr. K Sivan was crying and the Prime Minister hug him and said that government stands for them whenever they need us. ISRO had also planned that they would launch Chandrayaan 3 mission which is mainly focused on lander and rover because the orbiter is doing his work properly.
In Chandrayaan 3 ISRO would identify their mistakes which they did during Chandrayaan 2 and also they would land on the southern part of the moon by lander and rover.
Chandrayaan 2 mission is 90 percent successful and the remaining 10 percent will be successful in Chandrayaan 3 mission.
