To prepare Vikram for the Moon’s landing, scientists had to simulate an environment similar to the Moon. Tamil Nadu district Namakkal, situated 400 km away from Chennai, has soil that is similar to that of the lunar soil. ISRO scientists often get samples of soil from this area to create a bed similar to that of the Moon. Hence, soil from Namakkal played an important role in ensuring Chandrayaan-3’s soft landing on the Moon
