re: Johnson Space Center
One was about astronaut training (about 20 minutes) and the other was an in-depth look at the building of the space station (about 50 minutes).
There was a third but I can't remember its topic.
One I was surprised wasn't there was "Space Station 3D" which I'd seen before at an IMAX in Phoenix. That one was stunning since it was taken with dedicated 3D IMAX high res cameras in space. If you ever get a chance to see that one, it's the ride of a lifetime.
