The command module of Apollo 13 is currently in an awesome space museum(The Cosmosphere) in Hutchinson, Kansas, not too far from Wichita.
Well worth the visit if you are ever in the area. I've seen the museum a couple of times when I was out that way for work(

...I'm heading out there next month. Might have to check it out again).
The museum traces the history of space flight from the end of WWII to the present in a very well thought out presentation.
The museum is also home of the Libert Bell 7(??)-the Mercury capsule that sank in the Pacific before they could recover it after the hatch "just blew" after Gus Grissom's flight. I remember quite a few years ago when they found it, recovered it, and the museum restored it.
