Helium on the moon is much more interesting than helium on the earth.

Most of the helium on the Earth is from radioactive decay.

The helium on the moon, however, is from capture from solar wind... and has a higher concentration of helium 3. https://www.esa.int/Enabling_Support/Preparing_for_the_Futur...
