Throughout Pony history, often they have looked up into the night sky and wondered, "Are we alone in the Universe?"
Although they lack the technology to travel there themselves, it never stopped them from dreaming of distant worlds, of grand adventure throughout the cosmos, of epic space battles with lasers and massive explosions, and of encountering aliens, both good and bad.
Jebediah Kerman often did the same thing. That's why he signed up to be a Kerbonaut when the program first opened. Now, he's the programs top pilot, able to fly anything from Landers to Spaceplanes and even a giant mech suit. (Long Story, don't ask.) He landed on every body in the Kerbol system, is in the program with his two best friends, survived countless disasters, and met the love of his life on a mission to Laythe.
When the Agency asked him if he wanted to be part of the first expedition of Kerbals to travel to another star, they already knew the answer.
