2:00 I'm currently helping out with Asteroids@Home project on boinc that simulates asteroids physical properties (shape, rotation period, and direction of the rotation axis) by using the data from all-sky surveys and simulates the lightcurves to determine all of that The photo you got came from that project :D They weren't joking when they said it was time consuming to calculate the lightcurve. Right now my GPU has to compute ~1.4mil GFlops on each task given to it

[@DrachenGothik666]

He's undergoing chemo for Hodgkin's Lymphoma & probably a lot of his time is taken up with feeling like utter crap after treatments. He's also just crazy busy, working on several channels at once, a record company, writing, music, doing talks & conventions. And now with the cancer diagnosis, he's got his health to consider. Don't worry, he's still around, just more in the background for now.

IRL it's like 1:1. You still have to try to hit something to end up anywhere near anything, even in the asteroid belt. And yes I know you're making a star wars joke! It was funny.

[@balesjo]

I could imagine a day when people want to establish a long-term or permanent mining and industrial outpost would do so on an asteroid. Actually, for protection from radiation, it would be best to build their facilities underground or burrowed into the side of deep craters or other vertical terrain. It would have to be one rich if materials needed to extract oxygen, water, and materials for raising food, and with luck enough metallic minerals to construct habitats and other needs. From underground habitats, extend structures for docking spacecraft and transfer of materials and humans and which also deliver rocket fuel for return trips or further exploration. I know, sounds like a pipe dream, but it's these dreams that can lead to new ideas that do product the technology needed to accomplish it. Ad astra!

[@SuLokify]

Given the sort of timescales expected with terraforming and automatic/self-constructed megaprojects, one really great way of using asteroids is to heat it up until molten, then slowly spin it up and allow dense materials to centrifuge out. Then use a passive radiator to cool the rest of the asteroid back down - bam, solid rock with many of the useful materials removed.

[@australien6611]

I guess if that were true wouldnt all the metals be on the surface of the earth not in the core?

[@p.0-npcg.248]

Even with a extremely viscous melt this would require a hard shell of refractory high tensile strength materials that keeps it from scattering into drops from an already red hot donut

[@davaguco]

Very interesting

[@SC-zq6cu]

And this is precisely the reason why i don't think any mars or any near future planetary colony will ever exist or exist for long. Because economy ultimately drives long term expansions and there isn't anything we can get from mars or any rocky planet for that matter(except earth) that we cannot get from asteroids far more easily.

Space capitalists

[@dylanlafreniere3479]

At the moment it’s entirely more efficient if we ship factory’s into space instead of earth based to launch pre built satellites or structure into space. It make more sense to build with asteroid in space. But this cannot be the the best solution, we are missing some obvious advantages by simply not know the right questions to ask.

[@cgfreeandeasy]

First part: Mining materials in space to bring it down to planets.... even, if that isn´t mentioned in first hand (because for space stations), at the end of the lecture of that man, he speaks about stations on Planets. The problem to that is, that the metals in asterioids often had isotopes contained, that aren´t stable in gravitation (or other condition, that is usual on planets). So they decay through the transport to the surface (for example Platin191 to Iridium191 over electron-capture, as it may happend at the event, that killed the dinosauers 66 mill years ago - for that there was iridium in the asteroid, there is that unoverseeable layer of iridium in geological layers around the world and is connected to the impact. Albeit: not the iridium was in that asteroid, but platin191). So if they once transport random metals down to surface of a planet, they may initiate the explosion of a natural nuclear bomb. Albeit it is unclear, why that electron-capture happends. Maybe it is a interaction with atmospheric electric tension/potential, not gravitation (albeit it is until today not clear, what gravitation realy is - some fabulate, that this is not a physical force, rather a "space-time"-effect. The idiotic part of that account is, that even if that were true, it effect forces to matter, so there is force - in classical physics, also there is no motion without an initiating force or potential). And if the planet didn´t have propper atmosphere (as the moon or mars), maybe nothing happends. The only problem, that lasts, is the problem with the masses and the gravitation, that makes it complicated to land on planets with asteroids or even only mined ore. And there is anohter apprehension: The question, why earth has such a special atmosphere, also isn´t clear explained. Maybe it is all evolved, because of live in oceans, that evolved million years along and then, that life formed two things: Plant-life produced oxygene, what filled the atmosphere. And the other thing is, that such a special atmosphere was catched by neurological fields, that evolved also parallel to evolving of life in the oceans. So.... both pre-conditions for life on land. Whilst ocean-organisms did not need the atmosphere. The conclusion of that thought is, that, if you colonize humans on mars, you may get a manipulated atmosphere, that can influence earlier plans to mining metals from asteroids, because of electron-capturing happends, because of atmospheric potentials, that will change with the amount of humans on mars. And if that thought is right (more or less), it also has consequences for the science of climate-change, because of if neurolgical activity can influence such things, it also can regulate conditions, whereout a problem, like climate-change/warming, can emerge. Some would say, that all that is really wrong and totaly over all scientific expertise and knowledge. And, maybe it is. But:... scientific knowledge is not, what realy is (or can be). It is only the actualy knewed knowledge about reality. And there are maybe big holes in that knowledge until today. I am shure, that this is the reality of todays science. And there are maybe more forces, as we know of today. Maybe forces, that not came out of material existances, rather forces emergend out of potentials and other physical conditions and beings.

Reconsider the name of this video. I watch this channel because I love to learn about new stuff, especially about space exploration. “Why should we care” is a weird way to frame this topic.

They could really be one in the same. If we could offload heavy industry to orbitals? Or get minerals from asteroids instead of chewing up miles and miles of the earth? A lot of future tech is locked behind the ability to gather certain minerals that are difficult, or just very expensive on earth but are abundant in space rocks. Honestly, this is something I've been looking forward to since I was very young.
