Chandrayaan-2: India’s Historic Feet on Moon
Recently, Chandrayaan-2 developed by the Indian Space Research Organisation was launched to the moon by a Geosynchronous Satellite Launch Vehicle (GSLV Mk III).
Which are the features of Chandrayaan-2?
1. The journey is planned for South Pole of the moon, which is not much explored till date.
2. The mission’s main objective is to map the location and abundance of lunar water.
3. It consists of a lunar orbiter, a lander (Vikram), and a lunar rover (Pragyan).
4. It is launched using Cryogenic rocket engines that are highly efficient engines using a cryogenic fuel.
5. Cryogenic fuels are stored at extremely low temperatures in order to maintain them in a liquid state. Example- Liquid Hydrogen.
How is Chandrayaan-2 different from earlier moon mission?
1. The Chandrayaan-1 mission launched in 2008 had discovered the presence of water ice on the moon.
1. The current mission of Chandrayaan-2 is expected to carry this study forward.
2. Chandrayaan-1 was an orbiter mission while Chandrayaan-2 is an orbiter-lander-rover mission.
3. It is a quantum leap in technology and shows India’s progress in technology.
4. Study and findings of water on the moon are important if moon is colonised in future.
Why Chandrayaan-2 mission is important?
1. It is a scientific mission carrying 13 instruments with it.
2. The orbiter will map the lunar surface with a very high-resolution camera and Study on events of moonquakes like that of Earthquakes will be done.
3. Lander will dig into the moon’s crust and perform its thermal profiling.
4. Pragyan rover is a 6-wheeled rover slightly powered with artificial intelligence and will do a chemical estimation of the lunar dust and also search for water.
What is the way ahead for ISRO?
1. The mission cost of Chandrayaan-2 was around $150 million which is 4-5 times cheaper than similar American and European missions.
2. Missions like Chandrayaan and Mangalyaan prove the achievements of India in science.
3. To progress from developing to developed country, achievements in science are very important.
4. Such achievements create an inspiration among the young generations to take science as a career.
5. India’s next mission into space Gaganyaan is planned to be launched in December 2021.
6. It will be a crewed orbital spacecraft forming the basis of the Indian Human Spaceflight Programme.
