What I meant is stationary relative to the ring's axis of rotation. Point the nose toward the centre of the ring, and when the docking ports are aligned, thrust forward. Of course as has been mentioned already this seems like an unnecessarily difficult way of docking.

Another possibility is that the arm that grabs the Roci can rotate independently of the ring so that while the ring rotates, the arm and the ship are stationary relative to each other, and once the arm grabs on, it matches the rotation of the ring.

That was a gross exaggeration of how much the Coriolis effect would come into play there. I mean, if there's that much of an effect over that short a distance the difference in acceleration between your head and your feet would make just living there enormously uncomfortable; "down" would be a different direction at each point along your body. In reality a station as big as Ceres rotating at the speed it would need to rotate for that level of force, Coriolis effects over the distance that small would be small enough to be swamped by things like air currents, you'd never notice it pouring whiskey into a glass.

But yeah, points for effort.

But then by the time you get to the docking port, the station's rotation has carried in spinward. You need to match the station's spin so that you're stationary relative to the point on the rim, and that takes constant maneuvering thrust; you literally have to match the rim's *acceleration*, not a position.

Ah, here's where the attention to detail really grabs you though.

The brothel is in one of the poor parts of town, close to the centre of the asteroid. It's a cheap place to live because the coriolis effects are so uncomfortable.

If you notice later on, Miller pours a glass of water in the governor's office and the water actually flows straight down. The governor and all the other rich well-wallers live close to the edge, where you can hardly notice coriolis effects at all.

To be fair, it may have been exaggerated for effect, not just in terms of showing off the SFX, but to show that it was worse in that part of the station. That scene took place near the center of spin, where the gravity is low, the Coriolis is nauseating, and the rent is cheap.

Edit: :argh:

I suspect it's still greatly exaggerated.

Ceres is 950 kilometers in diameter. a =v^2/r. If it's spun to provide 1g at the perimeter (Do they ever specifically mention what the g level is? 1 g is definitely uncomfortable for belters, so I think 1 g is a big overestimate but let's go with it as an upper limit), 9.8m/s^2 = v^2/425000, v=2kps. 2kps sounds fast but for an object the size of Ceres it's less than .05rpm.

You're never going to feel Coriolis at such a low rotation rate, the threshold for discomfort is around 4rpm. The gravity falls off as you get closer to the axis, but the rotation rate doesn't change.

You thrust ahead of time so that you arrive there as the docking port becomes aligned. E.g if the dock is 90 degrees away, by the time it has reached 0 degrees you're already touching it.

Like imagine someone on a lazy Susan with their arm outstreched. You're standing right next to the edge with your arm out, and when your hands meet you clasp them together and you get pulled along

That would cause a non-trivial amount of stress. Instead of the ships thrusters changing the ships velocity vector to match the stations its the docking clamps.

True, but it does match what we see with the sudden acceleration in the show. If the docking clamps have a flexible component like an accordion that might also dampen the sudden acceleration.

Yup. I assume that's at/near the surface, so in practice is lower for the average poor Belter.

Not necessarily close to the edge but closer to the equator. The closer to the poles the greater the coriolis.

Rocinante has the correct orientation, but the cutting of the scene makes no sense. Miller should be decked when the thrusters fire, not when the clamps lock.


Docking like that would be easy enough if you had computer control and enough propellant.

The thruster fire knocked Miller off of his bed then moved ballistic perpendicular to the docking bay until captured by the clamps. The fall should be ecliptical but as with the spacing scene the fundamentals are accurate. Very nice touch and has gotten nerds talking.

If you're an Earther on Ceres, you''re probably rich enough to not have to deal with that poo poo.

Here's the scene in the governor's office I was talking about :



Same station, no visible coriolis fuckery. It's a really neat and subtle way to demonstrate the class differences on Ceres.

Yeah I'd blame spotty directing, and the executive decision to cram 3 episodes into a season double header. The second half of this episode seriously needed room to breathe, stuff happened way too fast, did we really need to end episode 2 in the climactic Thoth station raid and the Dresden headshot?

Yeah after re-watch, the pacing goes to poo poo in episode 2. I feel like it would have been better served for the 2nd episode to close out on the approach to Thoth, and then open 3 with the actual raid allowing it to spread out some, instead of how cramped it ended up feeling.
