๐ The name of the rover sent in the lander is Pragyan. Its weight is 26 kg. It rotates on the surface of the moon with the help of six wheels and works for 14 days. It has two payloads. The laser in this device hits the soil. ๐ฐ๏ธ๐ก๐ฌ
๐ By dissolving it, it helps in identifying the chemical elements and mineral wealth in it. Detects chemicals in the soil and rocks of the landing site. ๐๐๐งช๐ Vikram and Pragyan which get energy through solar panels are very short lived.. Their life span is only 14 days. That is why all these systems work properly as long as there is sunlight on the moon. ๐๐๐๐ When the sun sets - the whole becomes dark. At that time the temperature drops to minus 180 degrees Celsius. ๐ โ๏ธ๐ก๏ธ๐ Lander and rover systems cannot survive in such conditions.. After 14 days the sun rises there again. ๐๐ฆ๐ญ๐ฌ ISRO scientists say that if sunlight falls on the lander and rovers, it will be more beneficial if they work again. ๐๐ฐ๏ธ๐ก๐ But ISRO engineers say that they cannot say for sure that they will work again after 14 days.. ๐ฐ๏ธ๐ง๐ฌ
