Part 8/13:
Behavior of the Hatches
Footage shows astronauts in space suits opening and closing these hatches, with the covers reacting in a way that’s consistent with rigid, airtight materials. If the footage were underwater, the hatch would behave like a flexible, water-resistant membrane, bending significantly when handled. The observed behavior—covering shape retention and minimal deformation—supports that the environment is vacuum, not water.
