Came to know that there is one more main part of Chandrayaan’s mission, its to explore helium-3 resources from moon. It seems moon has abundant resources of helium-3 from earlier studies; which could be used in Fusion reactors to produce power. Following is an animation to explain how the fusion occurs in DT helium reactor. One atom of deuterium and one atom of tritium combine to form a helium-4 atom and a neutron. Most of the energy released is in the form of the high-energy neutron.
