Tiny picture frame (made of toothpicks) with the first photo of a black hole, 6. Mortar bomb shell I found in a forest, 7. Poker dice, 8.

Ok so here’s a little experiment: all my most liked posts include cute girls. Let’s see if Steven the Ultramarine can get as many likes:)
It’s a little quick render as I’m pretty busy but hope you like it. I feel like our ultramarine boys in blue would definitely drink some nice plain mineral water that’s refreshing and full of good ions that keep you hydrated on your crusade for the Emperor.
They chose Steven for the commercial as he embodies the spirit of the brand.
Hope you like it:)

@joemomrgneissguy SPACE MINING. HO BOY.
So when mining comes into a conversation, there are several 'laws' of mining and processing that I like to consider that people tend to forget:
Location and rarity of commodity
Location and rarity of extraction techniques/reagents
What is necessary for this operation to work?
Where does the finished product go?
Some of these are extraneous. Theoretically, we don't have to care that iron is common on earth and might be present on the moon, so it changes the conversation from "why?" to "how would we?". Same with extraction and reagents. If you don't care how expensive it is to ship- for example: water and carbon dioxide to the moon because you want to process He-3, nothing can stop you.
However, what will stop planning, is processing. Blowing up a rock is easy. Collecting the rock and breaking it into a usable form is not. If there isn't a plan for exactly what commodity is being mined and how to separate it and all the equipment that needs to be made to get it into a usable form, and a plan to get that equipment into space. God help the poor bastard.
And fundamentally, no matter HOW you turn it, people use the finished product. If there are no people where you are mining the Thing, you need to have a way for the Thing to get back to the people who need it. WHY are you mining the Thing? What is economic about the Thing being made? and Is it worth the money?
[angry geologist rant under the cut]
So the thing about space and asteroids is metals come in native form a lot of the time because there's nothing to oxidize them; it makes processing simpler and the density increases profit. This is usually what people talk about when they go off about space mining: Ohh, if we just reach this asteroid 400 years away there's so much Gold and Platinum! Ohh, if we just crashed a FUCKING ASTEROID INTO EARTH OR MARS we could be so rich!
However this is a LIE for two reasons: It's actually harder to process straight sulfides or straight metal because they aren't brittle. Instead of breaking into smaller pieces you can separate and process, they jam the crusher. Universities with mining departments often have huge chunks of impressive high-grade sitting around that were donated by companies when they jammed their fucking system. If you can't break it down, it's a useless fucking clump of rock.
Secondly, even if you have native metals clumped together like an iron-nickel asteroid, unless you want an iron-nickel product, you have to separate them. Since it's not brittle, you would have to pour a bunch of hydrochloric on it and wait for the reaction to dissolve the outer surface.
And all this is assuming the metals are on Earth. If not, you have to figure out how to do this in space. How much HCl will you need? How are you going to fly it up there? How are you going to break it down? How are you going to replace parts when they inevitably break?
The big "commodity" on the moon is Helium-3, which is extremely rare on Earth. (So yes, we have a need, and yes, there's substantial reason to mine it in a place where it's more accessible.) The logic starts breaking down around "getting it back" and "how does the operation work": In moon quantities (up to 15 parts per billion (ppb)), you have to mine about 150 tons to extract 1g of He-3. That's not unreasonable, to be honest, since economic gold hovers around 7-12 ppb. And technically you'd only have to heat the rock to 600-700 C. However, things do melt at those temperatures. Then you have to get it back to earth. Either a SpaceX-style return and come back, or a drop shipments- It's just insane to me though that we would use SO MANY RESOURCES to rip up the fucking moon, even with an automated system, when if you look at He-3 we already produce what equals 11 pounds of He-3 yearly from Oil and Gas deposits, it's just not collected.
I have more beef with planets that are theoretically resource-rich, but people just- don't care about getting them back to Earth? Venus has significant metal-Sulfides and Tellurides in its atmosphere, which is why people joke about the "floating oxygen colonies" on Venus. But congratulations! You've colonized a planet that is inaccessible to human technology because anything we've ever designed will dissolve. Same with Europa. To design something that works on Venus - not to mention extracts things in the proper form to be used in human conditions - and/or get them back to Earth means redesigning how we think of the properties of the periodic table.
With extraction, we play a lot with oxidation states, and one of the rules is to stay within Earth's aqueous conditions. If you oxidize anything too much, your solution will want to vaporize to oxygen. Reduce anything too much, and your solution will want to vaporize to hydrogen gas.
So, if you design anything on Earth designed for conditions on Venus, it will be unstable. If you design anything on Venus meant for Earth, it will be unstable.
Which is kind of the end of my rant, I guess. Don't crash something into Earth unless you can process it. If you can process it in space, can you get it back? Who's responsible when the thing breaks? Why the fuck is money being spent when 9 times out of 10 we have it here on earth with the conditions we're familiar with?
If we've somehow depleted Earth enough that we need resources from other planets, which would insinuate we have not figured out how to recycle our own metals, which is untrue, and likewise we have no business in space anyway- Where did all our resources go? Are we leaving for those other planets? Do we have faster-than-light travel to collect the new resources in a timely manner?
There isn't even water in space half the time and if you do have a colony on Mars and tech bros are going to process all the hematite to build their shitty underground Martian city, are they shipping water from the north and south poles to do this? Have they figured out how to renew the carbon filters that are going to be needed to get all the waste and organics out of it once it's used?
In my opinion, it's all just fucking stupid. Space mining tries to answer a question that doesn't need to be asked with people who don't know how mineral processing works who haven't thought what the logistics require and don't care that entropy demands even minerals in stasis don't last forever. But it's ~new~ and the dollar signs on metallic asteroids gleam in their eyes and I want to take out Elon Musk's kneecaps.

So I finished this portrait a few days ago and even though I very much didn't like the pencils I used I think it came out pretty neat 🙂
