Easy, I would use my suit, which provides me sustenance, to walk around the surface until I find a Spaceship.
Then I will destroy it and makeshift an SOS.
Then, I will steal that sweet Moon Buggy sat up there and drive around until I find that recent Japanese Or Chinese Moon Robot they sent and crashed. I will then repair it using spaceship parts and make them send help.
Then, freedom.
Do you try reading the Chinese found on Chinese fast food menu's?
