IMHO, the most interesting thing they did was with the palette. They were obsessed with getting not just images snapped by the satellite as the sky, but having them actually look good, and even a "smart" mapping algorithm to the in-game palette wasn't good enough for them. So they wrote an algo to simultaneously choose a palette for both the colours in the satellite image and the colours in the game's graphical assets so it would pick colours best for both of them, and then remapped both the satellite image and the game's assets to this new palette. Also, normally satellite images are denoised on the ground, but a partner had gotten a machine learning denoising algo running on the satellite.
One thing they weren't able to deal with was that the game tiles the sky background, which is fine because it's a tileable image, but obviously random pictures of Earth aren't (except the nighttime images, which are all black!). If they had had more time, I imagine they would have set up something like heal selection to merge the edges, but one of the problems was that in order to take images of Earth, the satellite had to be oriented in a way that increased its drag and accelerated its deentry... so ironically, playing DOOM was accelerating the satellite's doom.
