You need that living habitate to survive 6 months in 0g minimum, plus move it planetside without breaking anything.
You could expand the habitate to a larger area later, true, but there’s still like 7 mass cycles that need to be maintained long term, and this system needs to be robust enough to trust a few dozen people to. Otherwise, it’s just an extension of Earth’s biosphere and is dependent on regular resupply.

Ceres would be a way better start. Lots of water for shielding, consumption, and fuel; easy access to asteroid orbits; and a shallow gravity well to make transport easy.
Similarly, many of the icy moons around the gas giants would be good, also with decent mining, but better science opportunities too!
Our Moon is good too. Close, big enough to not need zero gravity setups. That’s actually about it really, it’s just right here. May as well do Orbit I guess.
Start with Antarctica and the ocean floor. That’s still 80% as difficult, and rescue can take 30 minutes, not 3 days or 10 months!

You need a very big one though, and humans need a more varied diet than soil bugs.
You’d also need to deploy the system, or find a way to maintain it all the way from Earth orbit to Mars’ surface.

1kg of oxygen is a good estimate, humand need 0.5-1kg per day.
Astronaut calorie budges is a bit higher than average, as would be for labouring humans. About 3000kcal, or 12 MJ.
I think more important than the raw energy and oxygen is sourcing the water, cleaning the water, producing the energy to electrolyse and heat, and maintaining the equipment necessary to do so. And that’s assuming all food is shipped in.

That’s a Scleral Ring and helps to keep the shape of the eye in fish, many reptiles, and birds. Fish don’t have round eyes (they’re shaped more like M&Ms or chocolate chips), and the ring helps support the shape when swimming. Most rings are just cartilage, but fast swimmers often have bony rings.
- Comment on How about the digestive system? 1 week ago:
That’s why we have the compound word “through-hole”.
90% of important parts on living things are pockets and manipulations of surface area, two things completely ignored by topology. Topology is interesting mathematically, and has meaning for traversal and knot problems, but it’s not really useful to describe reality.
- Comment on How about the digestive system? 1 week ago:
And yet each indentation could hold something, like cheese or a kitten, so each indentation in functionally different from a smooth surface.
Deforming a shape changes it, thus topology is a special case of specifically ignoring most aspects of a shape.

I think the problem would be getting enough reflected light and not too much radiant light from the compression and/or fusion plasma.

Yes, but at that point it’s not really voltage anymore. It would be more like a rapidly expanding cloud of electrons ionizing anything it came across.
It could be more focused though a magnetar though, and a magnetar might conduct the ionised plasma nearby, or even through the galaxy in interactions with the local supermassive black hole.

Well the path of least resistance is pretty full right now, the path of next most resistance seems like less bother.
- Comment on Sea Level 2 weeks ago:
The Sol-Jupiter system would have a bary center just 7% outside the surface of Sol. The effect of all the Gas Giants together can either center the syster in Sol’s core or move the barycenter 120% outside Sol.
The really weird thing is that the part of stars outside the core is more like an atmosphere. If the star gets hotter, the parts outside the core can expand. This is happening slowly as Sol’s core fills up with Helium and becomes denser, which fuses Hydrogen faster. So despite weighing less, the Sol-Jupiter barycenter will be engulfed within Sol’s envelope. Once Sol stops fusing Hydrogen in it’s core, the core will shrink and heat up, fusing Hydrogen in a shell around the core, which will cause the envelope to grow and engulf Venus and possibly Earth directly, and definitely contain the full system’s barycenter. After that it will release a bunch of mass in a planetary nebula, which will cause it to shrink a lot, and the remaining planets will probably orbit much farther out, which would throw the barycenter waaaayyyyyy outside of the white dwarf left over.

- Comment on Why do some people have so many tabs open on their browser? 5 weeks ago:
Can you not read the labels? I know Chrome will shrink tabs to just the icon, but you mention Pocket, so I assume you know about firefox, where there’s always at least 6 or so characters shown.
I have no issue navigating 150+ tabs (except that it takes a moment to scroll over them). It’s like a kitchen; half of the cupboads just have baking supplies in them, but I know exactly where anything is, or at least where to look. Baking soda is in the first cupboard right of the fridge, next to the vanilla, behind the salt. The paper on planetary radius vs mass I’m using for worldbuilding in my TTRPG is just to the right of the chunkbase map, and a bit left of the second youtube island, next to the other 12 worldbuilding research tabs.
This was before tab groups too. Now I can collapse those 12 tabs into one item, and do that for each of ~10 topics, which makes navigating tabs much faster.
Firefox mobile is a different beast though, because I can’t organize the tabs, and they’ll get reorganized by time (I think?) after 2 weeks when they get moved to Inactive Tabs. That’s more of a big pile that I sort through when I’m bored.

Huh, I’ve never had that happen. My 8 year old phone has difficulty with opening the home screen, but the tab list has always been smooth as butter.

We we’re hit especially hard because they shrunk each island individually. Just the Canadian mainland looks the same size as the states.
On the other hand, seeing Russia shrunk like that makes me think we could be bigger!
- Comment on Why do some people have so many tabs open on their browser? 5 weeks ago:
Not OP, but many topics last longer than a week.
I’m not going to finish Factorio in a week, and my collection of tabs on factorioLab, sheets, drawio, and the wiki are both interrelated and mark the several projects I have going. That’s also a topic that would be very annoying to reopen every week, and also would lead to bookmark clutter as most of those tabs will get closed when the projects are finished.
There’s also research tabs for things that will come up later. I have 6 open right now for configuring a smart home system that won’t get opened until I can actually see the system in person, but I don’t know when that will happen.
And there’s also long running series, like text stories, podcasts, or youtube series. That would be a nightmare to update bookmarks for, but those tabs will track progress just fine.
I suppose I keep tabs exactly because I want to keep interest for weeks, but I know I’ll forget all the details between sessions.

I keep seeing people talk about tabs lagging their devices, but I have never had that since 2008. Is that a safari thing?
- Comment on Why do some people have so many tabs open on their browser? 5 weeks ago:
The problem with Pocket is that it’s out of sight. That’s like writing yourself a reminder note and putting it in a box under your bed. It also doesn’t maintain tab groups, so a collection of tabs will get scattered and messy.

There are lots of reasons to have binocular frontal vision. Redundancy, differing info for optic flow, sensitivity, reducing the frontal blind spot, compensating for retinal blind spots, higher frontal resulution, seeing around things, depth perception…
Most of there are good for predators, but predation isn’t the only reason to have them.

Randall does have a lot of geology humor specifically. I wouldn’t be surprised if he knows a few geologist.
- Comment on This comic is missing a chunk of asbestos. 1 month ago:
I can see a little grain of truth in finding depressions and soft ground as the dowser shifts their body to stand level, which may indicate geological features associated with ground water.
Humans also have a really good sense of smell for petrichor, which might also be related to ground water, with dowsing just being useful to focus on suble things like smell.
Anyone who thinks dowsing can detect water directly is clueless or lying though, and dowsing has absolutely been used as a grift before.

Not all apples, but many. Including Macintosh, which was found along a road and could never produce viable seeds. There were only three trees for like 30 years before people noticed that they tasted rather good. All Macintosh apples today are grafts of the one surviving tree.
