What a cool coincidence. I was in the office over the weekend unpacking a U-HAUL stash of space artifacts and found that I now have a Lunar Orbiter high-gain antenna (the dish that would beam the images back to Earth).
Before Apollo, the U.S. flew robotic satellites around the moon taking analog photos in strips. The film had to be developed onboard the satellite in the onboard dark room (since the satellite would not return to Earth). The film was then raster scanned with a 5 micron beam and transmitted back to 🌏. A lot of work before digital cameras! More from Wikipedia
