MarkWhittington writes: India is preparing its second mission to the moon, the Chandrayaan-2, as Space Insider noted. The mission will consist or an orbiter, a lander, and a rover. It will be launched on an Indian-built Geosynchronous Satellite Launch Vehicle (GSLV) in late 2017 or early 2018. Defense Daily reported that officials at the Indian Space Research Organization are mulling making the lunar mission nuclear powered, presumably with plutonium-fueled radioisotope thermoelectric generators (RTGs). RTGs use the heat of the decaying fuel to create electricity. Both the American and the Soviet space programs have used RTGs in their various spacecraft, the most recent one being the New Horizons space probe that recently flew past Pluto.
