Nanodaemons: Selenography

Chang'e-4 is just the little rover that made it all the way to the dark side of the moon. But will it manage to complete its mission, when it has the entire half of the moon to cover with its little wheels and solar panels, when it has to protect the moon from all intruders and when on the other side lurks the nasty American rover that has won one fight already?

This is a Nanodaemons short story.
