This is Mars Base Camp. It is a concept made by Lockheed Martin, and a very cool one at that.
I had initially planned to put this in over the moon, but since no interior is shown in the plans, I am going to assume that there just isn't one.
I have stated that all objects in my project Over The Moon will have an interior, and I am going to keep that promise. Thus, I have unfortunately scrapped it from the list. But, I still love the way it looks, so I decided to make it as a separate map. If Interior ever comes out, I will be sure to add it into OTM! But alas, that will not be today...

In the zip file is a folder containing the resource pack and the world. put these into their respective places, and you are free to do what you want with it!

I recommend using my space suit for this map: https://www.planetminecraft.com/skin/space-suit-skin-overlay/
