Orbital station

What you're seeing

1. A dark, detailed station structure of trusses, cylinders and panel arrays fills the left of frame, with the Earth's blue, cloud-streaked limb curving behind it.
2. The camera drifts slowly, and the angle on the station shifts a little.
3. For a moment a small object appears in the space beside the station and moves near it.
4. The curve of the Earth stays bright on the right throughout.
