There is no way to get to see everything here in one day! We did the bus tour, shuttle Atlantis and an astronaut talk.
The bus tour may vary from time to time, the couple that we were with lives in the area and said they have never gotten as close to things as we did on our tour, that said, our tour guide/driver mumbled a bit so I think I missed some of the information.
My favorite part of the whole day was seeing shuttle Atlantis. It is displayed beautifully. I felt that I was very close to it and could see it well. A replica of the Hubble telescope is also in this area. There are enough information stations to learn about the shuttle, but also space to just look at it.
The astronaut talk was wonderful! The astronaut gave a short talk and then answered some questions. You could also get a picture with him afterward.
I did peek at the older exhibits and it looks like they have really been kept up to date.
