ISRO collects 'lunar' soil from Salem, TN to test Chandrayaan-2 rover,lander

"The surface of the earth and that of the moon are entirely different. So we had to create an artificial moon surface and test our rover and lander," M. Annadurai, who retired as Director, U.R. Rao Satellite Centre (URSC), formerly ISRO Satellite Centre told IANS.

The moon's surface is covered with craters, rocks and its soil is of different texture as compared to earth's.
