"text": "Good evening, and welcome to Gallery Seven. Outside, the rain taps softly against the tall glass panes, but in here the room stays hushed, warm, and full of suspended attention. Before you is a weathered bronze astrolabe recovered from a river crossing centuries ago. Notice the worn edge near the lower ring; that smoothness came not from time alone, but from repeated handling by navigators who trusted it during long journeys. As you move closer, look for the tiny engraved star marks arranged in uneven arcs. They are easy to miss at first, yet they reveal how practical knowledge and artistry once lived side by side. When you are ready, continue to the next display, where a series of field journals records the same route in three different seasons.",

I am sealing the lower corridor now and rerouting the last reserve power to navigation beacons. Crew status: four accounted for, one missing near the research bay. Oxygen remains limited, but we still have a narrow window to ascend if the port thrusters answer on the next cycle.
