5things huh.....
This is a tough one you got there......
Hmm, what do you have there on that moon base beside food and air....
Do you atleast have what you can find in a normal house, such has kitchen, tableware, Bedroom, living room, washing machine room, Space suit changing room, Air locked room where you can exit the base by pressurizing and removing air and so the air inside wont leak out if you perhaps wanna take a walk to perhaps take some picture and so on.
But ofc you got to have other communication beside internet and such, Computer is already decided to be located there but not perhaps what you would expect, more like a main computer for the moon base to operate without necessary repairs unless a rock happens to hit the base.
Necessary tools to do minor repairs after perhaps going crazy if you happen to do so or perhaps something gets broken.
Does the base have artificial gravity or does it consist only of the moon gravity?
Well if what i have stated above exist then all i would need to bring beside cloths that are not counted for and necessary stuff like toothbrush, razor and so on.
Then the five things would be.
1, Big fucking storage device made out of the newly developed(still under development as we speak) Crystal hard drive containing movies, anime, manga, books, pictures and so on...
2, A projector device that can show in wide rather then the simple square.
3, Big Telescope that is computer controlled and should be placed outside.
4, Speaker set to place around the base so i can hear what i watch.
5, A girl, ofc you got to have some company up there.
