Thumbnails are iffy (auto-generated? they're different sizes and some are missing) with visual inconsistency along the left-hand side, but this is minor.

Will there be a GitHub link on the main page when the website is deployed? Seems kind of weird to have available for the general public, if so.

The FAQ page is listed under "About" and "Resources" - not sure if intentional, and may seem slightly redundant, but it makes sense and fits visually.
Very minor visual thing: for the "Penny4NASA" header in the upper left, is it possible to move the "4NASA" part slightly more to the left? The space between the Y and 4 is a hair too much, but I don't think more than a few people will ever notice. It's probably fine as-is. And when you hover over it, have you tried making the 4 blue? It could be interesting to have the colors flip instead of making the entire thing red. But that's just a thought which may not work out -- not a recommendation or error in any way.
The graph on the main page doesn't show absolutely everything on mobile devices, but it shows enough to get the point across.
