Know, how likely is Vikram Lander and Pragyan Rover to be operational again?

New Delhi, September 26, 2023, Tuesday

Last month, ISRO achieved a major achievement by landing the Chandrayaan-3 rover on the surface of the moon. Vikram Lander successfully made history by making a soft landing on the southern part of the moon. The Pragyan rover, which came out of the Vikram lander, conducted research for 14 days with the help of solar and sent data.

14 days on earth equals one day on the moon, that is, if we calculate on the basis of the earth, there are 14 days of light and 14 days of darkness on the moon. In the absence of sunlight, the temperature drops as low as minus 200 to 250 Celsius. The batteries of the lander and the rover are not capable of withstanding the shock of such low temperatures. The rover is currently in hibernation. Although scientists cannot say for sure whether the batteries will work in the presence of sunlight on the lunar surface, they have not given up hope.

It has been sending signals continuously since September 22. Batteries can be activated during a period of 14 days. Continuous commands are being sent by ISRO. This work is being assisted by other orbiters and telescopes. In short, efforts are being made to revive the Lander Vikram and the Rover Pragyan. It is interesting to note that in addition to the minus 200 degree cold, another deterrent factor is discussed.

It is believed that some space craft from China, Russia and Japan are orbiting the moon. In such circumstances, the signal of Chandrayaan-3 may be interrupted. However, no explanation has been given by ISRO regarding this. According to the information received, China's Lunar Lander Chag E-4 and Rover-2 were reawakened after enduring extreme cold in 2029. China's rovers were also powered by solar batteries, but China used plutonium-238 metal, so that heat was maintained inside even though it was bitterly cold outside.
