Chandrayaan-II, India’s second mission to moon to be launched in April this year, said Minister of State, Atomic Energy and Space Dr. Jitendra Singh. Earlier, Chandrayaan-I had discovered water on moon. It will cost Rs. 800 crore for the mission. It had three components : an orbiter, a lander and a moon rover. So, it had to over come many technical challenges. The launch window is April to October but ISRO (Indian Space Research Organisation) would attempt to launch it in April. The lander and the rover would last a lunar day, which is 14 days, as they work on solar power. While, the orbiter has a life of one year. A location had been discovered where they would drop the lander and the rover. The location discovered has not been explored by anyone else earlier.
