Chandrayaan-2: ISRO testing for Moon landing

According to Kumar, several craters, resembling the terrain of the Moon, have been created on the ground at the facility to test instruments and sensors on the lander of Chandrayaan-2. “We are doing some tests with regard to the Moon landing mission of Chandrayaan-2. For that, an aircraft carrying some of the instruments is being flown over this simulated area at our facility in Challakere,” Kumar told on the sidelines of a function held at Physical Research Laboratory (PRL). 

“We have created some craters there. These tests are part of our ‘hazard avoidance and landing’ exercise. The lander is supposed to come down and land (on the Moon). We have to make sure that it lands at a place which does not have too much of slope. Otherwise, one of the legs of the lander would stuck in a crater,” Kumar said. 

As per ISRO website, Chandrayaan-2, India’s second mission to the Moon, is an advanced version of the previous Chandrayaan-1 mission. It consists of an orbiter, lander and rover configuration. The orbiter with scientific payloads will orbit around the Moon.The lander will soft-land on the Moon at a specified site and deploy the rover. The scientific payloads onboard the orbiter, lander and rover are expected to perform mineralogical and elemental studies of the lunar surface. In the recent past, Kumar had indicated that Chandrayaan-2 would be launched tentatively between 2017 and 2018. 

“There will be instruments on the lander. To make sure that these instruments work when it lands on the Moon, we are doing some simulations and that is one of the activities going on at Challakere” Kumar, who also serves as the Secretary in the Department of Space and Chairman of Space Commission, said. “Tests are also going on to check the engines which provide required thrust to the lander in order to bring down it’s velocity to compensate the lunar gravity during the landing,” Kumar added.
