Sources of the lunar atmosphere There are two main sources of the lunar atmosphere. One of them is outgassing, which is the release of gasses that originate from radioactive decay processes deep inside the crust and mantle of the Moon. The second source is through a process known as sputtering: atoms are ejected from solid materials on the…
