Dad wanted to go to the NASA Space Center in Houston last time we were in the US. But given the circumstances, we are marking this as done for him. It is so amazing to be in a place were science is at the forefront and using science for space travel and studies at that!. It was interesting to see what the astronauts had used during their missions as well as have the opportunity to touch a real moon rock.
Space Center Houston, Texas, USA ( Long, Lat: 29.5518° N, 95.0981° W)
