These photos are not captioned, but they do have adequate alt text for screen readers and the files have enough to get you started! Press f12 on your keyboard to see what the files are named. Do not fear the machine. (on a mobile browser you can press and hold on an image to read the hover text!) I encourage you to answer the questions these photos raise by using a reverse image search engine. Personally, my go-to reverse image search engine is Tineye.com. I'll be adding to this page as I stumble upon more NASA photos I can't stop thinking about. Or hopefully as I find the others I frequently think of but haven't yet tracked down. There's one from the Gemini program I'm losing my mind trying to track down, I know it's real I swear because I did a painting based on it!
Do not fear the machine.
