Absolutely fantastic experience. Do not let the somewhat humble exterior keep you from visiting. The admission is not cheap, but it is worth every penny, and they are entirely supported by admission. Even though it is not a giant space on the scale of the Kennedy visitors center or other such museums, it is absolutely chock full of amazing items, artifacts and space program related items.
I am an avid documentary watcher, so I knew a good deal of the information our guide shared, but I still found it very engaging. It is obvious that the folks working here are intensely passionate and well informed. Many of the stories they told were things I have seen in documentaries on the space program, so their information is top class.
After the tour, I spent quite a bit of time looking at all of the fascinating items in their collection from both the US and Soviet space programs. The memorial to fallen astronauts was very moving and as with everything quite well done.
Two comments for visitors. First, because this is an independent museum and the space is relatively small, they do not have any refreshments. Don’t go on an empty stomach - you will leave before you are ready if you are hungry. Second, they have a great deal of items that are not in protected cases and are marked “Do Not Touch” - younger kids may find this challenging, especially because many of the items are models that look like toys. They do have a room specifically for younger kids, but the main exhibits are, in my mind, better suited for kids 7-8 years and up.
Overall a TREMENDOUS collection. Do not miss it!
