Chandrayaan-2 or Second Chandrayaan is India’s second lunar exploration mission after Chandrayaan-1. Developed by Indian Space Research Organization (ISRO).
The expedition was launched by GSLV version 3 launch vehicle. The expedition includes a lunar orbiter, a rover and a lander built in India. All these have been developed by ISRO. India successfully launched Chandrayaan-2 from Sriharikota range on 22 July 2019 at 2:43 PM Indian time.
The Chandrayaan-2 lander and rover will attempt to land on a high ground between two craters Mazinus C and Simpelius N, located at a latitude about 70 ° south of the moon. The wheeled rover will run on the lunar surface and chemically analyze the place. The wheeled rover will run on the surface of the moon and collect soil or rock samples for analysis. The data will be sent to Earth via Chandrayaan-2 orbiter.
Chandrayaan 2 features
1. is the first space mission to conduct a Soft landing on the south polar region of the Moon.
2. The first Indian mission, which will attempt a soft landing on the lunar surface with domestic technology.
3. The first Indian mission, which will attempt to explore the lunar region with domestic technology.
4. 4th country that will make a soft landing on the lunar surface.
The orbiter will orbit the moon at an altitude of 100 km. In this campaign, it has been decided to send the orbiter with five payloads. Three payloads are new, while two others are improved versions of the payload being sent to the Chandrayaan-1 orbiter. It will weigh about 1400 kg at the time of flight. The Orbiter High Resolution Camera will give the high resolution picture of the landing site before the lander separates from the orbiter. The interface between the orbiter and its GSLV launch vehicle has been finalized. At launch, the Chandrayaan 2 orbiter will be able to communicate with the Indian Deep Space Network (IDSN) as well as the Vikram lander. The mission life of the orbiter is one year and will be placed in a 100X100 km long lunar polar orbit.
Chandrayaan 2’s lander is named after Dr. Vikram A. Sarabhai, the father of the Indian space program. It is designed to function for one lunar day, which is equivalent to about 14 Earth days. The lander is designed to execute a soft landing on the lunar surface. Unlike the Moon Impact Probe of the Chandrayaan-1 hitting the lunar surface, the lander will descend slowly. The lander will not perform any scientific activities. The lander and rover will weigh about 1250 kg.
The rover weighs 27 kg and will be powered by solar power. Electric power generation capacity – 50 W. Chandrayaan 2’s rover is a 6-wheeled robotic vehicle named Pragyan, which translates to ‘knowledge’ in Sanskrit. It can travel up to 500 meters (½-a-km) and takes advantage of solar power for its functioning. It can only communicate with the lander. The rover will move on the surface of the moon with wheels, collect samples of soil and rocks, chemically analyze them and send the data up to the orbiter from where it will be sent to the Earth station.
Benefits of “Chandrayaan-2” to India
After the earth, India will emerge as the leader in the race for geographical dominance on the moon.
After France’s America, India can also become a country with military-critical space command.
The world came to know about ISRO’s ability to drop powerful rockets and heavy payloads.
ISRO’s ability to demonstrate in the field of communications, sensor technology
The proposed manned mission to India’s space “Gaganyaan Mission” in 2022 will clear the way.
Will become the fourth member of the club of three powerful countries sending mission to the moon.
Data from payloads placed in Chandrayaan-2 will reveal the presence of water and minerals there, which will start scientific experiments.
