As you know I am a space nerd. So I had to go to Houston to visit the Nasa Space Center! There I could touch an original moon rock! And I could also see the original Control Center of the moon landings, the Apollo 17 capsule and the last existing Saturn V rocket!
There were also life sized mockups of the ISS, Soyuz, Orion and Boeing capsules for the astronauts to train on. And other new and upcoming NASA tech like rovers and robots!
