The thumbnail view looks great. I like the extra info.
It's tough to remember the commands for thumbnail view since you only see them for a second. Maybe a little chicklet that stays in the upper right would help.
If I was doing this, I would start in thumbnail view, then go to slide view when an image is clicked. I'd add clickable left or right arrows in addition to the key navigation, since it won't be immediately obvious that the viewer is in slide mode. Maybe an up arrow, and also the escape key, would take the viewer back to thumbnail view (instead of the chicklet I mentioned).
As far as the image sync I'm not sure how that works. Maybe NASA has an API where you can filter on keywords? If not you might have to just keep syncining until they're done posting pics of Artemis, and manually curate them.
If you're looking for future expansion, you could add other categories too, maybe groups of thumbs based on mission or something.
