The National Aeronautical and Space Museum was a free admission museum run by the Smithsonian Foundation, just like any museum in Washington. It has the most outstanding space science and technology in the world, and like a country that sent spaceships to the moon, a model of Apollo 13 was displayed at the entrance, and the moonstone was also touched. From various rockets to spacecraft, there are many displays of spacecraft and some of them can be directly displayed, making it a more beneficial time. On the left side of the entrance, there is also a cafe where you can do simple cookies.
