Part 7/10:
Reflections and Docked Capsules: The presence of a docked Dragon capsule, with its angled windows reflecting Earth’s surface, provides direct visual confirmation of a real environment. The reflections precisely match the visible portions of Earth passing underneath.
Illumination and Shadows: The daylighting on the ISS and the changing shadows on Earth's surface follow predictable patterns based on the station’s orbit, Earth’s rotation, and the sun’s position, aligning with established physics.
