Pragyan: The most difficult test: If sunlight is not found, Pragyan will be lifeless on the moon: On September 7, 2019, Chandrayaan-2 (Chandrayaan 2) will be on the moon at exactly 1: 55 minutes of the night. After landing, the 6-wheeled Ignition Rover will break away from Vikram Lander. This process will take 4 hours. It will come out at a speed of 1 cm per second. The 27 kg Rover is a 6 wheeled robot vehicle.
Rover Pragyan name from Sanskrit
Its name is derived from Sanskrit, which means ‘knowledge’. Rover Pragyan can rotate 500 meters (half a kilometer) on the moon. It has two payloads. Its dimensions are 0.9×0.75×0.85. The most important information about it is that its mission life is a lunar day. A lunar day means one day of the moon which is equivalent to about 14 days of the earth. It works with the help of solar energy. The rover can only communicate with the lander.
Active only for 14 days
After reaching the lunar surface, the lander (Vikram) and rover (Pragyan) will remain active for 14 days. The orbiter will work for one year after reaching the moon’s orbit. Its main purpose is to communicate between the earth and the lander. The orbiter will map the surface of the moon, so that the existence and development of the moon can be ascertained. The lander will check whether earthquakes occur on the moon. Whereas, the rover will detect the presence of mineral elements on the lunar surface. Its total life is 1 lunar day which means about 14 days of Earth.
Solar energy will be charged
During one day’s journey on the moon, it will have to work with its own energy for 14 days according to the Earth, if it continues to receive solar energy there, it will also pass its most difficult test. Knowledge will be automatically charged through solar energy and will send signals from the moon to us on earth.
The mission has mission payloads, also known as orbiter payloads, in a way that is the full functioning of the rover. The Terrain Mapping Camera 2 will send a digital Elevation model of the entire moon, which will reveal many more mysteries of the moon.
It has two large area soft x-ray specto meters, which will be able to know which compositions are in the elements present on the lunar layer. It also has solar x-ray monitors which will be helpful in opening the secrets associated with the moon.
Discovery of Water
The mission payloads also have an imaging IR spectrometer which will tell us whether there is water on the lunar layer of the moon, in addition to this there is a radar that will tell the measurements of the polar region as well as the water in the second layer here. Ice is not that. Apart from this, three more instruments have been installed, which will be helpful in opening layers of life on the moon and all the mysteries associated with its future and ghost.
Let me tell you, Chandrayaan-2 is actually a new version of Chandrayaan-1 mission. This includes the orbiter, the lander (Vikram) and the rover (Pragya). Chandrayaan-1 had only the orbiter, orbiting the moon. India will land a lander on the lunar surface for the first time through Chandrayaan-2. This landing will be at the south pole of the moon. With this, India will become the first country to land on the moon’s south pole.
