You don't really understand the Size of Outpost Paradiso, until you see that the Lakon is cruising around it doing 130ms. Given the fact that we know the approximate size of the cylinder, can someone guess what is the size of that station? I'm guessing more than 10km by far! Also, given that the outer ring is @1g and the inner @.5g, how much gravity would the cylinder have? :)

ps: Before someone comes out and writes about FD giving us the actual numbers, I would like to remind him that this is much more fun.

If I remember my physics, the centripetal force is proportional to radius. The large ring looks to have about twice the radius of the smaller which makes sense for 1 and 0.5g respectively... so judging by the cylinder size.... 0.1 or 0.2g ???

5km diameter I think. Although it does look bigger which makes me think I got it wrong.

Counted 32 spars around the outer ring. So 11.25 degrees separation between them. Took about 3 seconds for one spar to come about to roughly the same point where I noted were the leading spar was when I started counting. So 3.75 degrees per second.

So assuming I can count (a risky proposition) and that my timing isn't terrible (it is) and knowing that the internet is awesome I plugged those values into Calctool and faffed about with the radius until I got more or less the stated 1G.

The Coriolis is about 4km in diameter with 1g in the extremities, but from the video I think the Orbis rotates much, much slower. Anyone else seeing this, or am I just projecting?

Makes sense.
If it's larger the radius is bigger and so the required rotation rate for 1g is lower.

Newsletter #27 says it's 8km in diameter, which by my calculations means it should take ~127 seconds to rotate to generate 1G at the perimeter.

@ Dante80

You're right. I was just eyeballing and roughly timing over a short period of time so that translates into huge errors.


@ nicomak, JimmyC

Seems a lot closer to the size mentioned in the newsletter. 4,000m radius at 2.75 deg/s would give .9G. 4,500m radius at 2.75 deg/s would give 1.05G.

The thing about lower G section being better for the elderly and the heart. Well maybe at first, but over time won't your body adapt to the lower strain and become weaker?

Ok...we got an estimate of 8km for the large ring in the Orbis station.

Now for the next thing. What is the length from toaster to tail? It looks a little larger than 8km, not sure though. Any bold testers want to do a little science?
