As from today we have a map from the moon from incoming body's on the moon, see yellow dots. That is not such good news for building something on the moon. But then i saw a structure in these impacts. If the moon has a metal core it would be drawing these to the middle of the moon away from the poles. So i drew a circle to image that core, you see it as the blue circle. Then i drew some orange lines closer to the poles and what we see is a saver zone from impacts. So i guess that would be a choice of preference for the moment.
