Moon materials can be used to produce ships and space structures, satellites, propellant, etc. You can have a space elevator on the moon today with a titanium cable. It will actually be profitable.&lt;p&gt;Most importantly, colonising the moon is tractable in terms of emergencies: if someone on the moon suffers an accident and needs a surgery, they could be in a hospital on Earth in a day or two. If their shelter is damaged, or supplies are needed, we can send help to the Moon and have it arrrive before everyone is dead.&lt;p&gt;You are on mars and suddenly are suffering from liver disease? You are probably dead. It&amp;#x27;s going to be like the life of iur first Abtarctic explorers, when they get in trouble, there is no help. Many don&amp;#x27;t return, and noone stays there to live. To this day noone &amp;#x27;colonised&amp;#x27; Antarctica.&lt;p&gt;Mars settlement is only viable when we have a spaceship factory on the moon, nuclear engines, and we could send the equivant of a large marine research vessel to mars, so 10,000 tons usefull payload, every month.</text><parent_chain><item><author>gameswithgo</author><text>Electric cars and vertical rocket landings were ideas you could show would work eventually  with a little napkin math.

For one there is a compelling reason to colonize for at least a portion of the population.  It would be the opportunity of a lifetime to study planetary geology up close, put terraforming theories to the test, and produce fuel&amp;#x2F;water for further space missions using the reduced gravity and atmospheric drag.&lt;p&gt;On the other hand the fact that &amp;quot;going for a walk&amp;quot; will be extremely difficult will motivate increased focus on cavern excavation and other construction underground.  These are &amp;quot;necessities&amp;quot; on mars but would be &amp;quot;interesting&amp;quot; in the gobi dessert.</text><parent_chain><item><author>gameswithgo</author><text>Electric cars and vertical rocket landings were ideas you could show would work eventually  with a little napkin math.
