space by Katherine T. at InsiderPages
I can't say that this even begins to compare with the Kennedy Space center, but what space museum can? I've always been an avid fan of space museums, and although this one can't compare to KSC, it is still a great museum. San Diego is the home to the Ryan Aircraft which built the spirit of St. Lous and a hotbed of aeronautics, which is something you should definitly check out.
