The answer that across on my mind are...i can't imagine how to survive on the moon with or without the other but... I will try to recalll and find The Ark, a crashed alien space ship on the moon from Cybertron and maybe.. I can try to fix the robot or the spaceship or telecommunication radio, contact the NASA and try to get back to Earth using a Space Bridge which Sentinel Prime use it to transfer the other robot from moon to the Earth. Maybe they still have a Space Bridge device. How do you like that?
Essentially, i'm on the moon and have to get to the other side or try to get back to earth by using only the supplies at hand. So i have to prioritize the list of supplies. For those of you who always watching science fiction movies, this might be a good time to recall all the movie about life in an outer space, moon, spaceship etc..
FootNote ~ What would you do if you are the the astronauts?? hahahahahah
