Backlog Conquering - Deliver us the Moon - The Sixth Hour, or so

This is the sixth video in the Backlog Conquering series featuring the game Deliver us the Moon being played on PS4. I think we are near the end as in this video we got a lot of story. many questions were answered, and we explored a lot of the station. The video ends with me being somewhat stuck with a puzzle. i know what the pieces are, i know how it should work, but by the end i hadn't worked out one part.
