Our professor wanted to introduce us to the wonders of using the metro to navigate through Washington DC. We were grouped into teams of three and were given a list of places. We had to go through various places on September 10th, 2017. In this image, we stopped by the Smithsonian National Air and Space Museum. We were all interested in space, so we looked around for quite a while. I especially learned how astronauts were able to go to the bathroom in space, which can be quite challenging in 0 G.
