What Lies Beneath the Craters?

In preparation for an upcoming lunar mission LEGO scientists were pouring over pictures taken during the 1960's moon landings to try and find a suitable area for basecamp, when they zoomed in they made a surprising discover...poking out of a crater in the background was the unmistakable image of an alien periscope, focused directly on earth!  

What (or who) really lies beneath the lunar surface?  Only time will tell.  Suit up explorers!

This build is intended to capture the excitement of the unknown, and the thrill of discovering that we are not alone!

Built from exactly 250 parts the base is 20 studs wide by 24 studs deep, and approx. 16 studs high!
