Sadly, I would not recommend this museum to anybody. It is not bad, but there are many much better ones elsewhere (e.g. in San Diego and in Washington).
The two (small) highlights of our visit there were:
1) playing with sound enhancer located in the outdoor space park
2) trying to land a space shuttle using a simulator... Anil was much better at it than I was, but still, neither of us should really be an astronaut...
Here are a few pics:
