The California Science Center is absolutely worth seeing, but you should take several hours to see it. The space department and the space shuttle alone are worth the visit. In principle, you do not pay admission; However, you can make a donation. To see the space shuttle, simply buy a ticket for 3 euros to the left of the entrance (an absolute MUST!).
Very informative exhibition that is fun, our highlight is the Endeavor, seeing a space shuttle up close is breathtaking ... plus a lot of information about the space shuttles and their missions, a small area with merchandise attached - at very reasonable prices ( Nasa shirt for example for 17 dollars) also an experience for children. The exhibitions are also very imaginative and worth seeing.
