There is plenty to gain from it. But it is a long term prospect. Unfortunately today, everyone is after the quick profit (You know like building bombs.)<p>Some examples:<p>* A telescope on the moon could be larger due to the reduced gravity, and have a better view without the atmosphere.<p>* Helium-3 mining, not to mention plenty of other resources that are starting to become somewhat scarce and hard to reach on Earth.<p>* Since the gravity is a 6th of Earth&#x27;s, launching space exploration vehicles from the Moon would be much easier and thus cheaper.<p>* Colonizing the Moon would be first step in getting all man&#x27;s eggs out of one basket, so to speak.<p>* If man can setup a sustainable ecosystem on the Moon, then he can do so almost anywhere. It really is a great testbed for expanding into the cosmos.<p>* The Lunar Olympics will be awesome!
