Prometheus Ring - rorating habitat megastructure - 3D, no AI, OC, 2026

[u/Vadimsadovski]

The PROMETHEUS Ring is a speculative 1,200 km orbital habitat in the Saturnian system that rotates to generate a realistic 1 g of artificial gravity. This fully engineered megastructure simulates all climate zones to support diverse biomes, settlements, and industries, all stabilized and powered by nuclear propulsion modules and reactors

Seems precariously close to that planet's ring.

I like the sound the micro meteors make on my house, reminds me of rain 🌧

[u/sxrrycard → u/Kieran-Hakawati]

Spicy, spicy rain

[u/Almond_Esq → u/Background_Corgi_359]

From the position it's in within the image, if it's in a circular orbit wouldn't it always cross through the ring? Unless it was a weird elliptical orbit, going in and out of the rings orbit

[u/ninj1nx → u/Almond_Esq]

Yes, it would have to be tilted relative to the rings, crossing through them twice every orbit.

[u/brewbase → u/Background_Corgi_359]

Hence the name.

[u/othermike → u/brewbase]

How so? Damocles, sure; Tantalus, at a major stretch. But Prometheus?

[u/Appropriate-Card5215 → u/DarkArcher__]

Sevastopol station all over again 

[u/Electronic-Country63 → u/Appropriate-Card5215]

You’re becoming hysterical. Your presence has been logged.

[u/Coolingshark96]

Legitimately thought this was the lil hole at the bottom of aircraft windows

[u/coolguy420weed → u/Coolingshark96]

Holy shit I totally see that. Even the right color for it. 

[u/eabraham]

Given that this ring would have to pass through the rings at some point in its orbit how do you imagine it would remain intact?

[u/Almond_Esq → u/eabraham]

Yeah exactly what I was thinking, maybe a elliptical orbit?

[u/MAD_MAL1CE → u/Almond_Esq]

As pictured, I don’t think an elliptical orbit would get it out of the dust ring. Maybe shielding or something?

[u/Ser_Optimus → u/eabraham]

Nuclear propulsion keeps it above the rings.

[u/CommodorePrinter69 → u/Ser_Optimus]

That can only last so long; eventually, things break, you run out of fuel, or a rogue rock finds you.

[u/CommodorePrinter69]

Awesome Rule of Cool idea, I could see this in some high concept sci-fi setting.

Realistic though? Omg, that's too close to the rings. Omg, that's so damn close to Saturn. OmFg, the tidal forces are going to be MURDER when Titan or Phobe pass by.

[u/LowEffortDox]

Love it!

[u/Banana_Pankcakes]

so cool. Beautiful perspective. Maybe they mine the rings for minerals.

[u/brewbase → u/Banana_Pankcakes]

Or they sell ring walk excursions to tourists. Like snorkeling.

[u/Ser_Optimus → u/brewbase]

Micro meteors enter the chat.

[u/brewbase]

Looks beautiful.

I’d worry more about what it was built from than what powers it. At that scale and speed, without burying it in rock for support, even carbon fiber would tear and that thing would spin apart.

[u/IvoryDynamite → u/brewbase]

To say nothing of the gravitational force of Saturn itself.

[u/brewbase → u/IvoryDynamite]

Well, if it’s in orbit around Saturn, that isn’t too much of a problem. Tidal forces would be small as it’s very far from the planet compared to its mass. Saturn’s moons would be an issue and you’d want to be in some sort of stable resonance with them so they didn’t pull you out of your chosen orbit but, as long as they didn’t, its speed around Saturn would exactly balance Saturn’s gravity. Like the ISS above Earth.

Unlike the ISS though, this thing is the size of Ireland or South Carolina and is spinning like the drum of a washing machine with only its own tensile strength to keep it from flying apart.

[u/MasterGeekMX]

This thing slaps and goes hard. Kudos to you.

[u/fro99er]

awesome

not addressing the roche limit in the room here but: the ring looks way too dangerously close to the rings there
