To come to the California Science Center and see the space shuttle up close and personal is an incredible experience.
To add in an IMAX of the earth from space is amazing.

Note that if you don't have a reservation for the shuttle (you need to make it in advance and online) you can use the IMAX ticket for entrance without a reservation.
