What important to think about the lunar outpost on the Moon?

I think only by moving underground to use the moon dirt or soil as a cover over your head is it practical because of meteors and meteorites. 

It is less of a problem for Astronauts in the Space station simply because they are orbiting around Earth and the earth's gravitation pulls meteorites and meteors into the atmosphere which usually (unless they are really huge like the one that killed the Dinosaurs) are burned up when they hit the atmosphere.

However, the moon has no atmosphere at all, so if anything the gravity of the moon just speeds up impending doom for anything on the surface of the Moon. So, only by moving underground in case a meteor or meteorite hits where the station is can they be more protected there without holes in their station with the air all leaking out when some meteor or meteorite hits at full speed and made even faster than it was before by the gravitation of the moon and hitting them with no atmosphere at all to protect them there.
