Wonderful, your ending surprised me. I would like to suggest a couple changes: He thinks to himself all the possibilities, all the faults, all the years of science, research, history, shattered. could be reworked along the lines of: He thinks of all the shattered scientific possibilities, faults, research, history (that brought him here). And chips to chirps?
I love how you are able to use a few words to explain so much of what’s going on, Your line he doesn’t understand the words frightened me, like a person lost in a foreign country, this guy is on a foreign grey planet, and doesn’t understand a word being spoken.
