Lunar Mission-What's Special About Chandrayaan-2

By Iha Rashmi Verma on July 15, 2019


There was a lot of public uproar over the proposed lunar Mission Chandrayaan-2 which is all set to be launched in July 2019 from Sri Harikota in Andhra Pradesh. This will place India as the fourth largest country to launch the mission that landed on Moon, after USA, China, and Russia. 

The Moon Mission emerges as the biggest scientific achievement for ISRO. The Chandrayaan-2 comes up with a lot of new features in it which sets it apart from the mission Chandrayaan-1. Lunar missions are the one that orbits around the northern side of the Moon as the southern side is considered a shadow region where the sunlight hardly reaches, a necessary component for the mission to operate. 

Now let us first have a quick view at the first moon mission Chandrayaan-1which was launched from Satish Dhawan Space Centre, Sriharikota, using PSLV C-11 on October 2008. The Mission detected traces of "Water" along with Magnesium, Aluminum, and Silicon on the Moon. They discovered the northern pole of the Moon. The mission did not land on the moon rather it just orbited around it as there was no Rover and Lander were involved in it.

Mission Chandrayaan-2


A Comparison

The mission will be launched using the GSLV Mark III rocket. Unlike the earlier Moon Mission, Chandrayaan-2 will emerge as the first mission to explore the Southern Pole of the Moon. It is made up of an Orbiter, lander named "Vikram" after the founding father of Indian Space Science Research Vikram Sarabhai and a Rover named "Pragyan" means Wisdom. The spacecraft weighs nearly 4times heavier than its predecessor— 3,877kg.

It's predecessor Chandrayaan-1 sent its lander crashing into the Moon, on the contrary C-2 will use rocket technology to soft-land Vikram(lander) carrying it's Pragyan rover on the lunar surface to land between two craters Manzinus C and Simpelius N scheduled for September 6 this year. 


Lander, Rover, and Orbiter

After the lander has landed between the craters a 6 wheeled Rover will come out on the surface to collect essential data on elements over the moon surface. It'll carry 2 payloads to enhance the study of the lunar surface. The rover once landed can travel along with the range of 500meter from the lander. The orbiter will carry the 8 payloads to conduct a study of exosphere of the moon using Terrain Mapping Camera 2 and provide a 3D image of the moon surface.


Background

Earlier India was set to launch the mission in collaboration with Russia but the deal scrapped due to the emergence of some technical differences between these two countries.


Benefit Offered By This Mission

Though the mission brings with itself a great scientific achievement it has other socio-economic benefits to offer as well—the cost of the mission is less even lesser than 1000crore which further encourages the other private space agencies to work with ISRO. Secondly, it made India scientifically and technologically advanced puts it even on a greater foot than Israel, a country that has been known for its scientific excellence. Plus factor is the Foreign currency that it'll generate helps in maintaining the country's balance of payment account which in turn will benefit the economy as well.

Hence, The new mission provides the country an opportunity to celebrate it's a massive achievement in the field of science and technology and is also set to benefit the country socially as well as economically in the long run.
