Helium-3 Propulsion
From Wikipedia, the free encyclopedia
Helium-3 Propulsion is a proposed method of spacecraft propulsion that uses the fusion of Helium-3 atoms as a power source. Helium-3, an isotope of Helium with two protons and one neutron, could be fused with Deuterium in a reactor. The resulting energy release could be used to expel propellant out the back of the spacecraft.
[edit] Advantages
Helium-3 is proposed as a power source for spacecraft mainly because of its abundance on the moon. Currently, scientists estimate that there are 1 million tons of Helium-3 present on the moon, mainly due to solar wind colliding with the moon's surface and depositing Helium-3, among other elements, into the soil.
