Untill October 16th 2022 you can visit the Space Expo - The Human Quest in Atwerp. I visited the expo last week. The tour took about 90min and I liked the anecdotes from Lieven Scheire.
The expo gives a good historical overview of the space race between Russia and USA. There are some original pieces and 1:1 replica’s: Spoetnik, Vostok, Mercury, Apollo capsule, Moon Lander cockpit,... historical documents and objects: letter from Armstrong and personel object from our first Belgium astronauts Dirk Frimout and Frank de Winne. There are four "audio guides" to make it interesting for all ages.
Interesting was also the Mars area explaining how the first Mars crew will "settle" on Mars.
