For most of these, you don&#x27;t have to go to the moon. On the way to the moon you get to space where there is even less gravity (Hubble isn&#x27;t on the moon)<p>Having some gravity may be beneficial for the colonists, but AFAIK, 1&#x2F;6th the gravity wouldn&#x27;t help much there.<p>About the only reason for going there instead of into space would be to use materials present on the moon. Of the materials, Helium-3 seems the best candidate, but it is far out, as it would require extensive mining on the moon and transporting it back to earth or space or setting up a huge colony on the moon.<p>A second reason might be psychological. I think a moon colony, where one could make trips into the &#x27;outback&#x27; for a few days, may have advantages for the long-term mental health of colonists (from a space station, people could go on space walks&#x2F;flights for a few days, too, but such trips would look more like &#x27;going nowhere&#x27;.
