I'm sure this is a very educational center, however we wouldn't know. After paying $77 to enter, we tried to get on the tour tram and they informed us it was full for the day. We asked for a refund so that we could return a different day which they refused.
The tram ride is a first come, first serve event. However the sad part is we went on a weekday, not weekend. We arrived BEFORE noon, and the parking lot was maybe a 1/4 full, and they were still maxed out on getting to the space center. God only knows if they had just 1 school bus of children show up for an educational experience.
If you are a tourist visiting this area, I would personally avoid this attraction and save your money and time.
