Incredible and well maintained place with lots of interactive exhibits and stargazing on a few nights. Weaknesses: no cafeteria or place to buy water, snack, nothing! I ended up leaving earlier than I wanted because I was starving; upon arriving at the main entrance, there was no one at the front desk to advise on how and where the exhibits were; some rooms with historical equipment were without any security (only cameras), which I think dangerous for the collection.
Overall, a very good experience!
