Moon Base

From the Introduction:

To the untrained eye the moon's surface might look featureless and dreadfully monotonous. And it is true, that this crater seems to be only one among many. Only once an observer gets close to the crater's edge will the base inside the crater become obvious. The base is not much to look at, still two habitat modules have been set up close to the crater wall promising a safe haven. In addition a ramp has been erected connecting the floor of the crater with the higher surrounding ground. While this ramp is wide enough for various vehicles it is not particular sturdy. Even given the moon's low gravity it would be reckless to traverse it with heavy vehicles.
