India succesfully launches Chandrayaan-2
What is Chandrayaan-2?
Chandrayaan-2 is India's second moon mission after Chandrayaan-1 Made by the Indian Space Research Organisation (ISRO), the mission is planned to be launched to the Moon by a Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk III). A proper landing would make India the 4th country to achieve a soft landing on the Moon, after the space agencies of the USA, USSR, and CHINA .the mission landing is expected on 6 September 2019.
Why travel to Moon?
The Moon is that the nearest cosmic body at that house discovery are often tried and documented. it's additionally a promising workplace to demonstrate technologies needed for deep-space missions. Chandrayaan a pair of tries to foster a brand new age of discovery, increase our understanding of house, stimulate the advancement of technology, promote international alliances, and encourage a future generation of explorers and scientists.
Why was the previous Launch Cancelled ?
Launch of Chandrayaan-2 was originally scheduled for 14 July 2019 at 21:21 UTC (15 July 2019 2:51 IST) but due to a technical glitch on the launcher it was cancelled 56 minutes before launch and postponed to 22 July 2019 at 09:13 UTC (14:43 IST).
What are the objectives of Chandrayaan 2?
The primary objectives of Chandrayaan-2 to demonstrate the power to soft-land on the satellite surface and operate a robotic rover on the surface. Scientific goals embrace studies of satellite topography, mineralogy, elemental abundance, the satellite layer, and signatures of hydroxyl group and water ice The satellite can map the satellite surface and facilitate to arrange 3D maps of it. The aboard radio detection and ranging also will map the surface whereas finding out the water ice within the south polar region and thickness of the satellite surface. Chandrayaan-2 can inform the situation and abundance of satellite water for exploitation by the long run satellite base planned by the Artemis program.
What are the modules in Chandrayaan 2?
Chandrayaan spacecraft, with a mass of 3.8 tonne, will have three modules comprising of the Orbiter, Lander (Vikram) and Rover (Pragyan).
This is the first time that ISRO is attempting to soft-land a module in extra-terrestrial Space.
Once the Lander and Rover, enter the Moon’s gravity, they would be in a state of free fall. That could end up in crash-landing and destruction of instrument.
Because of lack of air to provide drag, these instruments cannot make use of parachute like technologies. To enable a smooth landing, the speed of the Lander just ahead of touchdown should be 3.6 kilometres per hour or less.
The Rover, a six-wheeled solar-powered vehicle, will detach itself and slowly crawl on the surface, making observations and collecting data.
It will be equipped with two instruments, the primary objective is to study the composition of the surface near the lunar landing site, and determine its abundance of various elements.
Every Indian should be proud As this is a great achievement for ISRO!
