Cool. This reminds me of an old short story "Christmas on Ganymede". In that story Ganymede had an indigenous population that funnily enough was described as "they can speak English but when they do that you wish that the couldn't". Yes the story was meant as comedy. I just checked on Wikipedia. Apparently written by Isaac Asimov. The article says written 1940 and published 1942.

[@Kelnx]

For us old timer nukes, that 0.08 Sieverts figure for radiation on the surface of Ganymede is equivalent to 8 Rem per day. While not lethal short term, that's a pretty strong dose. For comparison, after working in nuclear for decades I've only had a total recorded cumulative dose of maybe half that. I could get my lifetime occupational dose on the surface of Ganymede in half a day probably. It won't kill you but do that enough times and you likely have cancer in your future. Heavily shielded or underground habs would be a must for colonization.

[@jessedutton3112]

NASA's limit is 600 mSv per lifetime, or 7.5 days on the surface of Ganymede. So, yes, you are exactly correct.

I wonder why Callisto wouldn't be picked instead, as a "crown jewel" of Jupiter. Also rich in water and various resources, far enough from Jupiter that radiation is even lower (even taking Ganymede's magnetic field into account), and its outer orbit might be a bit easier for ship transit purposes. While also making a good base to exploit the rest of Jupiter from.

Because Ganymede has its own magnetosphere and receives more luminosity compared to Callisto, the fact that Ganymede is geologically active is an advantage. And building artificial magnetic shields isn't that complex

This is a true story. Way back in high school one day we all gathered together on campus near a tree and decided to make Maddie, our strange classmate, that we were far in the future and living on Ganymede having sparked fusion on Jupiter and migrated humanity out there. We were celebrating our 50 year class reunion, that's how we all came to be together in a perfect replica of our old high school back on Earth. Maddie fell for it and was disoriented the whole rest of the day being completely unable to remember his class schedule. Sometimes Maddie ingested certain molecules that he, and anyone, probably shouldn't. Bear in mind that the aforementioned 50 year class reunion will be next year and we knew very little about Ganymede since the Voyager spacecraft had not yet arrived at the Jupiter system, and would not for several more years. Yes, I'm pretty old by now but avoided ingesting dangerous molecules for the most part and still have a functional brain. Mostly.

Callisto would be better. Specialized RTG craft could assist in diverting other carefully selected small moons around Jupiter to add to the mass of Calisto, as there's lots to choose from. Mass drivers on other moons could send select materials to Callisto. More mass, more ability to hold an atmosphere, protect from radiation and protect from micro meteorites, and make it easier for human and other organism health.

Isaac, I’d love to hear your thoughts on atomic printing. Especially if that leads into the ability to deconstruct existing materials down to fundamental particles and rebuild them with different atomic weights.

Honestly, since getting a decent idea on how much more efficient habitats are versus planetary colonization, I have lost a lot of interest in the specifics of colonizing specific planets or moons. Other than geology research and the like I don't think we would ever bother colonizing instead of building habitat stations of whatever configuration we decide is most practical.

[@corbynite2004]

@@puresowns215 I tend to feel the same way… maybe each of these moons will have max 10,000 people living on them at any one time to get the extraction systems set up and then back to space they go to live in comfort and assemble more habitats. And thinking about how those 10,000 people would live while they work isn’t that interesting to me… I tend to go straight to ‘why can’t they just manage the robots from a comfortable habitat in orbit instead of going down to the surface?’ … Maybe they wouldn’t be extraction colonies but temporary tourist/geologist/historian outposts erected while the moon is still standing.

[@michaelpettersson4919]

Do that and I demand that the name is kept. So it will be something like "Ganymede station". At least for the first one if there is enough material for several O'Neil cylinders.

Issue with terraforming ice moons that's often overlooked is that they're Ice Moons - warm them up and you get a water world with a planetary sea that can be more than a hundred kilometers deep, and with no input of nutrients from continental erosion and little to recirculate that which falls to the sea floor, that's going to be a mostly dead ocean, especially if the sea floor is mostly composed of high-pressure ice. You can bring your own and create local open-water ecologies(tho you'll need to oxygenate more or less the entire ocean with said pocket-ecologies before you can can have animals) but that's far from a thriving planetary ecosystem.

If bigger is better for Fusion, we always still have Fission for small homesteads and facilities. Fission reactors can get extremely small, and if the photos from russian nuclear subs in the 90s are accurate, we already have traditional fission reactors that could fit in the back of a van. The Fallout-universe concept of having a fission reactor under the hood of your car might be closer than we think. We probably don't want to use them for terrestrial cars, but on the surface of an airless moon where you already have to radiation proof everything, well it might be fine then to run your rover on a under-the-hood fission reactor.

The inside layer being a superconductor at liquid nitrogen temp. Have the nitrogen *leak* to a tesla turbine, basically another layer in the same box... It spins, the container as a whole spins, have a coil around it. You now have a very efficient generator. Bonus. Making liquid nitrogen also separates out anything else in the air. Including CO2.

Moot point, even if the radiation question were to be answered, you're still stuck in low G. That's bound to have all kinds of bad effects for long term exposure. Until a proper fix is found, telepresence and perhaps an outpost akin to the space station's time frame would be the only feasible Ganymedian effort. Not even the sight would be worth the recuperation that one would have to go through or the meds they'd need for long term habitation on Ganymede. Ultimately, it's about "effort". Is it worth the effort to colonize a moon like that when a space station would be far more appropriate (and easier as human resources go)? I think not. Humans will have to stick to same or close to same gravity as Earth does, because that's how we evolved. And THE biggest reason for that is not just because of the health issues, but also because of what humans are... which is a really vile race that still (in this long) hasn't understood that fighting each other is utterly meaningless and that money, wealth, power... wanting them, are just symptoms of a deranged mind that needs to be placed under medication. Some people tend to want to see the best in humanity, i just see what happens now, with several wars that are happening because some human shaped refuses are wanting for power, while the rest of the human race is struggling under troglodytes with ambitions of grandeur who think that it's "ok" to pollute our planet's sky (without asking anyone, really) with space trash just so they can squeeze MORE money out of people who are clueless to the effects of their actions. Yeah, no. I'd rather ban any space flight in the first place if this eventually leads to settling and therefore, creating, yet another issue. Humanity as a whole needs to cook longer before it can even consider something like this, because we think too fast and feel too slow. And honestly, this feels like it would be a mistake.

Orth, Djuppitor, Morkuray - except these he speaks quite standard English. I'll try to use that pronounciation, as well - sounds kinda cool.

What’s bad is the radiation from Jupiter

[@samr.england613]

Yep! And "they" don't much talk about that fact in this lame video.

I have done a lot, I mean, a lot of thinking about all this. I imagine, that until we colonize Venus we will instead live in rotating space habitats and use the Moon as a refining center and ship production facility, but live in space. Similarly, Mars we will end up abandoning as a living center and instead mine it and live in space. Venus is the only planet capable of maintaining humans as we exist right now, all other planets or moons will wait until we are uploading ourselves into robots.
