So, you have heard about the media BUZZ of Chandrayaan missions of ISRO. And if you are wondering – why is Chandrayaan 2 a big deal and how it has made every Indian so proud.
Let’s DKODE Chandrayaan Mission as India attempts a real moonshot in its Deep Space endeavours.
The Mission Impossible?
The GSLV-MARK3 is a 3-stage rocket, consisting of a pair of S-200 solid boosters that are lit at the time of lift-off followed by a core liquid L-110 stage that burns hypergolic liquid fuel and a CE-20 cryogenic upper stage that uses liquid hydrogen as fuel.
The Chandrayaan 2 consists of three main components
Chandrayaan 2 will be the first interplanetary mission for the powerful launcher.
1. The first, also with the same name as the overall mission, is the orbiter. This will carry the other two components and will be placed in a circular lunar orbit, at an altitude of 100 km above the lunar surface.
2. The second is the Vikram lander, which will be soft-landed on the surface, and will carry a set of instruments to conduct scientific experiments.
3. The third will be the Pragyan rover carried aboard Vikram, which will be deployed onto the surface. This autonomous vehicle will carry its own set of instruments to conduct experiments over a planned 14-day life span.
There is possibility of the presence of water in permanently shadowed areas around south pole of the moon ( as proven in Chandrayaan 1 .
In addition, South Pole region has craters that are cold traps and contain a fossil record of the early Solar System. ISRO plans to use the experience for more challenging missions in the future, such as touching down on an Asteroid or Mars, or sending a spacecraft to Venus and carrying human beings to planets and moons.
The Chandrayaan 1 mission launched a lunar orbiter and an impactor. The impactor ended up ejecting sub-surface soil that was analysed for the presence of lunar water ice.
While it did not complete its mission life of 2 years, the Chandrayaan 1 had several achievements. It was the first interplanetary mission for ISRO, and heralded the way for other missions to follow, including one to Mars.
Chandrayaan 1 – The most significant scientific achievement was the discovery of water on the Moon.
Other achievements of the mission include the creation of detailed three-dimensional maps using over 70,000 images taken by its cameras, a study of the process by which water may form on the Moon, and a study of past tectonic activity on the Moon.
Chandrayaan 2 will land a ROVER vehicle on the south pole of the moon which will perform on-site chemical analysis and relay data back to earth.
The Chandrayaan 2 orbiter will circle the moon and provide information about its surface.
ISRO states that the payloads will collect scientific information on lunar topography, mineralogy, elemental abundance, lunar exosphere and signatures of hydroxyl and water-ice.
The terrain explored by the ROVER is of great scientific interest due to the rocks’ old age; at 4 billion years old, scientists say the zone likely is composed of an ancient magma ocean. Chandrayaan 3 mission is planned for 2024 for future moon exploration and help ISRO to setup habitat on the lunar surface.
Did you Know
Chandrayaan 2 will take 53 to 54 days to travel the 3.84 lakh km from the earth to the moon’s surface.
Chandrayaan 2 lander mission to Moon will cost ₹978-crore. In comparison a Avengers film is made at Rs 2,443 crore.
14 payloads on the Mission will study topography, seismography, mineral identification and distribution, and surface chemical composition. It will be the first mission to the moon to conduct a soft landing on the south polar region which has a lunar surface area much larger than that of the North Pole and remains in shadow.
Russia had pulled out of Chandrayaan 2 as a partner, citing financial issues. Some reports stated that NASA and the European Space Agency were interested in participating but ISRO proceeded with the mission on its own.
Every Indian is Immensely proud Today : PM Modi on Successful launch of Chandrayaan 2
India will become the fourth country on the earth to achieve a soft landing on the moon
- Algorithms wholly developed by India’s scientific community.
- One of its kind Rover capable of conducting in-situ payload experiments.
- Lander capable of ‘Soft Landing’ on the lunar surface.
- GSLV MK III is the most powerful launcher India will be using. This launcher is fully designed and manufactured in India.
- Chandrayaan 2 is the first interplanetary mission for the powerful launcher.
With renewed interest in putting back the man on the moon and colonising distant planets and the moon, day is not for when holidaying in space and the moon may become a possible reality.
