Responsive Multi-Page Space Tourism Site w/React

I used this project to teach myself react over several months in my free time. It was a challenge every step of the way but also incredibly satisfying. I'm still working on making the live page work properly, just click around and things will load. Appreciate any advice and critiques <3 (especially if you have any advice on properly loading the homepage without having to click around the nav bar, please T.T).
