Crossover with Kerbal Space Program, a game available at this site.

A mysterious object crash-lands outside Ponyville. An orbiter returns from space. One causes fear, the other causes surprise. Two species of intelligent creatures from opposite sides of a planet make first contact, and they eventually become friends, starting the first intercontinental alliance in the history of the planet. After all, what's a space program without worldwide support?
