Unlike the International Space Station, which orbits in continuous microgravity, a rotating station spins about a central axis so that centrifugal force presses occupants outward against the inner hull, mimicking gravity. The felt "gravity" scales with the square of the spin rate and with the radius: a small-radius station must spin fast enough that Coriolis effects (dizziness, altered balance when moving radially) become noticeable, so real designs favor large radii and slow rotation. Classic concepts include the von Braun wheel (a modest spinning wheel proposed in the 1950s), the Stanford Torus (a mile-wide rotating ring habitat for thousands of people), and the O'Neill cylinder (a much larger paired-cylinder habitat). Docking with a spinning station is nontrivial: incoming craft either dock at a non-rotating hub near the axis, where relative spin is minimal, or match the ring's spin rate before final approach. This scene shows a simplified wheel station with a rotating ring, a stationary-feeling hub, glowing habitat windows, blinking beacon lights, and small ships drifting nearby.

• To simulate 1g, a station with a 55 m radius (like this scene's ring) would need to complete a rotation roughly every 15 seconds (~4 rpm).
• Rule of thumb for comfort: keep rotation below about 2-3 rpm to minimize Coriolis-induced disorientation for occupants moving around.
• Larger radius = lower required spin rate for the same apparent gravity, which is why big designs (O'Neill cylinder, Stanford Torus) favor comfort over compactness.
• The ISS has no rotation and stays in continuous freefall (microgravity), unlike the spinning habitat depicted here.
• Docking is typically done at a non-rotating central hub near the spin axis, where relative velocity between ship and station is lowest.
• Stanford Torus concept (1975 NASA study): ~1.8 km diameter ring, rotating about once per minute, housing up to 10,000 people.
• Station-keeping requires periodic thruster burns to counter orbital decay and any residual wobble introduced by mass shifts inside the ring.
