Oh man - I feel a lot of history with these images - they actually inspired one of the first online businesses I tried to make. I wanted to put one of these images on my wall, but they were niche enough that I couldn't find anybody selling them. I printed one myself using Zazzle, but then I started thinking that it would be cool to create a place where anybody could share cool niche images they found and have them au…

From the description on that poster "The artist’s share of profits from sales of this poster will be donated to NASA." How, Though? You can't donate to NASA
Isn't NASA quite well funded already? Sky is the limit (or not..) of course, but I'd rather prefer a donation to those with immediate needs.
Details of the NASA budget can be found at the inevitable Wikipedia page:

I think it doesn't need to be massive, it just needs to have massive radius. Could be as simple as having a really long and strong wire between two habitation modules. And you can start small (low distance, slow spin, little gravity) and increase gradually. Expanse is neat, but spinning asteroids isn't realistic. The idea is that the acceleration at the surface of Ceres is 1/3g, pointing outwards (i.e. you fall "out"…
Very interesting point about the wire. Seems like a great idea and definitely worth exploring, but imagine if that wire got cut ;) > but spinning asteroids isn't realistic Ceres isn't an asteroid. It's a dwarf planet. It's not a pile of rubble. It's big enough to be round from its own gravity. The only object in the asteroid belt with that status, actually. > That would imply that the ground/rocks etc literally float…

> From what I understand, a structure needs to be quite massive to get meaningful gravity from a rotating hull unless you attempt to approach ludicrously unsafe angular velocity which would make repair / docking a big challenge The reason it has to be so massive is that otherwise the difference in the G-forces between your head and your feet can make you sick[1]. 1: http://www.spacefuture.com/archive/inhabiting_artif…
They talk about it in the book, it actually makes some of the characters sick

From what I understand, a structure needs to be quite massive to get meaningful gravity from a rotating hull unless you attempt to approach ludicrously unsafe angular velocity which would make repair / docking a big challenge. In The Expanse , Ceres station was spun up over many, many years and still only achieved about 1/3G. Not to use a fictional universe as a basis for science but afaik they at least tried to do t…
There's also Medina station which has the massive drum they end up spinning. They then grow crops in it. I love the expanse, such an amazing series of books
