[@richardgreen7225]

Suppose each habitat (or group) has a self-sufficient ecology. Since communication is cheap and free, dominance by information control seems futile. In such a situation, what sort of "dependence" would "independence" be about? Hint: Finance. - Recent history: "Colonies" and "imperialism" was based on resource extraction. There were whole continents for the Europeans, with their superior weapons and organization, to exploit via resource extraction and taxation. Eventually, the sheep resisted the fleecing and the enterprise of physical subjugation became onerous and was displace by financial inter-dependence. To profit from resources (material, labor, location) one needs a market. So there is inter-dependence between supplier and consumer. Newly "independent" nations often lack the technological resources of more "advanced" nations. To bootstrap their economies, they need to trade resources for technology. To become independent, this bootstrap process needs to lead to equality of knowledge and R&D capability. - Future history: Even when you have robots building robots from a huge supply of materials, everything has a price because "ownership" (capitalist or socialist control makes no difference) creates scarcity via *prioritization*. In a truly "post scarcity" ecology, so much resource is available that "prioritization" becomes personal rather than social. At that point, "dependence" has disappeared. The only remaining priority might be physical safety (the interplanetary equivalent of air traffic control).

What is the possibility that for a mining operation on an asteroid that the habitat will be tethered perpindicular to one axis of rotation a sufficient distance to keep the tether taut. The habitat then rotates around the centerline of the tether*. I expect almost all operations on the asteroid to be down by remotely controlled or semi autonomous equipment. The human operators are there mainly to solve problems, make crucial decisions etc. Plus the habitat also functions as their transport to and from the asteroid. As to viable elements to mine either highly valuable elements needed for industrial purposes or those needed for space based agricultural uses. *the habitat could be a fairly simple cylinder attached to a truss work boom with its power supply and drive at the other end. The tether also functions as an "elevator" for accessing the surface. The "elevator" being a simple powered drive that clamps on to the tether the person doing the EVA simply attaches themselves to.

[@animistchannel2983]

That would certainly be a viable way to do it in some cases. It seems to me that each asteroid, depending on size, spin, composition, richness, etc, will call for a custom solution.

I've been thinking for a while about the possible solution to the Fermi Paradox that's basically: interstellar travel is hard, and why bother when you have a whole galaxy worth of colonizing space and materials in your own back yard if you just look at more than planets.

[@animistchannel2983]

Yah, I've pointed that out before too. The universe is "only" 13 billion years old, and with starlifting technology you can make home stars last for trillions of years. A few exploratory interstellar colonies might form just for the novelty of it, but this channel has already described a ton of reasons why that's problematic. Even if our solar system started feeling dull and you did start a new one on the next star over... now you have another bunch of eternity to fill up there. Given the actual likely time scales like that involved, you wouldn't see a galaxy "getting full" with civilizations for hundreds of billions, even trillions of years in the future.

[@slateslavens]

Isaac, I've seen hinted at somewhere one last special reason advanced technological race might no make it to space: Gravity. There's a gravity threshold above which chemical rockets are worthless - they simply can't develop enough thrust to lift themselves. I'd love to see this fully explored.

[@nkordich]

In addition, high-gravity worlds will likely have thicker atmospheres that would hinder traditional rockets. However, that's only one aspect of getting to space: lighter-than-air vehicles make more sense in heavier atmospheres, so aliens would get more out of rockoons (balloon-launched rockets). Since obstacles to launch would prevent them from launching satellites that we pretty much take for granted - weather and communication - they may be more likely to have developed aerostats further than we have, so while rockoons may seem outlandish to us, launching rockets off vast airships may seem a logical next step for them. Thick atmospheres and high gravity might affect alien worlds in other ways - mountains would not rise as high and would be worn down more quickly, powerful winds and storms collecting speed over a smoother world might make any sort of aviation more of a challenge (this in turn might lead to them developing evacuated tube grains for transport, which in turn may put them ahead of us in developing magnetically accelerated launchers). Opaque clouds may mean they never engage in casual stargazing, astrology, or astronomy until they develop radio. A species that developed in higher gravity may also be even less well-suited to zero gravity than we are, as well. I expect gravity on its own wouldn't prevent civilizations with more advanced technology from heading into space, but it does put a greater hurdle in front of them to justify the first steps. I wouldn't mind seeing an episode that considered the problems that aliens might face getting into space that are different form our own. Or things that might make getting into space easier, or just different and more complicated, such as a planet with a natural debris ring (an obvious navigation hazard, but maybe a huge resource of material already in orbit).

A thought about your comment about space stations around heavy metal rich asteroids like psychi. Depending on its structural composition. Tunneling might be less viable then simply picking up iron rubble chunks from car to shopping center size and lifting it to a orbiting smelter. Or drilling out ore and taking it to a orbital smelter. But you wouldn't want the hot smelter in tunnels with you. Further, zero G offers some very attractive options with metals. My main point though is given one of the biggest users of bulk steel might well be constructing big stations, say O'Neil colony stations. Liquid E steel from smelters could go straight to ship yards (station yards?) building stations that would be shipped to the customer desired location. The liquid metal injected into "mills" sliding along the edges of a O'Neil hull edge, depositing multi deck layers in ring layers from one end of the drum to the other, and along any other structures edge. Shipping it to site would be a bear, but the idea of delivering major oil derricks to points around the North Sea would likely freak past Scottish lord as well. And yould need to give it a while to cool down afterwards. So a leasurely delivery timely could be fine.

Has a method been invented to smelt metals in zero, or near-zero gravity? Current smelting methods rely on gravity. Inventing zero-g smelting could make someone incredibly wealthy in the future.

[@animistchannel2983]

You grind everything down to grains or powders in the raw and centrifuge it, and just scoop off the layers one by one. Then if you want you can use lasers to heat the separated powders in a "crucible-steel" type closed container method. A tungsten tube & screw-cap as a crucible won't melt until over 3400°C, so you use that to hold whatever else you want to melt. Or you can do combinations and variations on those. For basic on-site prospecting, you could just do the grind & centrifuge part on location and send sealed containers of each type to market according to whatever's worth sending. The bulk "tailings" of base mineral grains can be formed into construction & shielding blocks of various densities like concrete or foam/sponge material and used or shipped in bulk. Of course, if you send an O'Neill Cylinder mother ship to manage the mining expedition, you can do each process in whatever amount of gravity you want, at your convenience. That also means miners don't have to live in micro-gravity, but come home at the end of each shift to pleasant conditions and family, etc.

[@dsnodgrass4843]

Not to mention that huge amounts of energy are required to generate smelting-level temps. This makes me think they'll need a central smelting operation that they send the ores to.

That reminds me of Jule Vernes novel about the golden meteor. Astronomers find it and it will miss earth if it wasn't for someone inventing a tractor beem to safely land it on a pre purchased piece of land in Iceland.

At one time in various places, iron/steel would have been worth its weight in gold. To the Sioux, gold had almost no use or value at all. They called it "the yellow dirt that makes the white man go insane." To them, copper or fine chert was more valuable. Commodities change value all the time. In the future with cheap gold, it would still be useful as an anti-corrosive coating and just to put a shine on things. It might be of similar value as brass is now.

[@triularity]

I could imagine early on, pushing one or two smaller asteroids into earth orbit to use as nearby test cases for mining/colonizing. It would be much easier (and cheaper) to spend a few days traveling each way than almost a year to get people and equipment to it to experiment with. At that range, time slots could be allocated to let private/commercial interests to develop/test their research (maybe similar to Ansari X Prize initiative).

[@blueturtle06]

I have loved the idea of mining asteroids for years. In many space games that is where you will find me in the asteroid field gathering resources for others to use. What I am wondering if you will do a video on refining materials in space? What will be the power consumption compared to earth based foundries. What are some of the possible new materials to be made in micro gravity (such as new types of steel with no air bubbles ect). The actual types of furnaces we could use and where. Could we possibly modify a Tokamak reactor in space not for fusion power but at lower temps and power to create a new type of furnace for use in space?

[@altha-rf1et]

wonder how many O'Neil cylinders can be built if mine all the asteroids

[@sdprz7893]

Probably a couple million.

[@rojaws1183]

There is only one way to be sure so let's start mining.

[@stefanr8232]

If your cylinders weigh 2.39 million tons you have enough mass for a trillion of them. Some parts of asteroid mass like the sulfur and oxygen are not very useful for cylinder construction so you might only get half of that.

[@gary6549]

About six. Trust me I have done the maths.

[@michaelpettersson4919]

If you are going to mine large asteroids it makes the most sense to turn the asteroid itself into both factory and habitat. This would be the most cost efficient and safest thing to do. After you have a sufficient number of factories built you can redirect small and medium sized asteroids straight to the factory for processing.

[@seriousmaran9414]

In most cases of smaller asteroids it might be better to build a suitable mining ship capable of producing one G by revolving and move that to the asteroids. The mining ship would have a basic crew of engineers, farmers, medical staff but little more. Everything possible being automated. Gold might be nice short term but simple amount would cause a supply glut and possible drop in value. At the moment we have this issue with the supply of diamonds, far more in storage than the market wants, sold by advertising exclusivity.

[@AsmodeusDHare]

This is where you turn that gold into circuits.

[@seriousmaran9414]

@@AsmodeusDHare true, but with that much gold you might be putting it on roofs to save money on tiles.

[@animistchannel2983]

@@seriousmaran9414 Yah, that's what I'm seeing. Mining mothership Cylinders with on-board processors to sort stuff in low gravity in the middle. People and farms live farther out in more normal gravity. Water reserves in the form of lakes and streams you can fish and swim in. Life in space will turn out to be... just life. Small and pebbly asteroids you just pull in the middle and chew up and process as you go. Bigger solid asteroids you either drag along behind you on a tether while you chop them up, or you pause for bit. The biggest ones like 16 Psyche you park in orbit and send people down to work in shifts like any regular job, then pack your product off to market when the holds are full. As for gold... I think it will eventually have about the same value as brass. It's still pretty enough for decorations, and it makes a good anti-corrosive coating for things that don't get a lot of wear & tear.

Asteroid mining is always so interesting because it is so incredibly easy and profitable that we might even see it (though I don´t think it will happen before 2080)
