To begin with, I looked at websites such as SpaceX, NASA, National Geographic and View Space to see what typography they were using. I also looked for Inspiration on Behance.
I used Google Fonts and Adobe fonts to look through a number of different typefaces. I even brought some into Figma so that I could try using it on my own content instead of relying on the font previews every time. I narrowed it down to 4 different typefaces.
