SOOO Many things to do here. You can take a tour of the Johnson space center, where sometimes if you lucky you can witness astronauts training, and take tours of certain building where they build space vehicles. Back in the Space Center, theres a HUGE gift shop, and a large playground, with many interactive things to do in it, and its so big, they need multiple guards to keep it in order. You can see many space artifacts, like recovered Apollo mission space capsules, and they even have a flight simulator where you can fly the space shuttle, and you can witness how astronauts live their lives out in space, lik what they eat and how they take showers. They even have half of a space shuttle with all the buttons to flip and press.
