Mark - Yes, through my job, I am over at the US Space and Rocket Center, http://www.spacecamp.com/, all the time. I work on the Space Shuttle among other NASA programs. Even as an adult you can go through space camp! IMHO, next to the Smithsonian in Wash. DC I think we have the best space museum in the country. If you have any questions please do not hesitate to ask.
