I've got a number of these. Apollo 11, "cause the crew were sheer badS. And don't forget Mike Collins. Explorer 1 "cause everyone overlooks it when mentioning Nasa missions. Freedom 7, cause Alan was a total badS.
This one, is my favourite. First flew in 0.25, later fueled it up and used it to circumnavigat Kerbin twice (sent it once on a botched attempt in 0.25). Currently on display outside KSC. It's name is the Spirit of Kerbin.
