This is a great place to visit. If you want a tour though, there is a six month waiting list. However you can go up there to get your NASA gifts, and you might see a few dear while you are there.
You will see the sister of the Mars machine which they test on some red dirt which is meant to replicate the Mars environment. There areas with memorabilia, but most of the lab are REAL projects they are working on. It is a great place to visit if you are into Space stuff.
