Maybe space resources can help Earth survive. But, like the Polynesians who settled the Pacific, that's really not the primary reason humanity wishes to explore & settle this new ocean, the depths of space. (Quote below is from Christina Thompson's excellent book Sea People.)

"...Occasionally, there is famine or some other type of trouble, but usually it is a matter of chiefly ambition or pride." (Important. I've often been told the reason Polynesians explored & settled the Pacific is a desperate need for resources. Polynesians' own stories disagree.)

Fun Fact: The US produces almost half of the global helium. The Qatar thing is a big problem, but pretty much the only country that isn't affected by it is the United States. Also: we can make helium. It's produced by radioactive decay & is concentrated in natural gas reservoirs
Eric Feigl-Ding@DrEricDing

FUN FACT—helium cools the superconducting magnets in more than 14,000 MRI machines used in hospitals worldwide. We lost the largest helium extraction plant in the world in Qatar. US reserves running low. Helium cannot be produced de novo. Any helium escape is permanent.

Trying to explain that using only three mounting holes is actually better than four, because four can overconstrain the alignment of the assembly (I broke a tap in the fourth hole)

Mission complete. After three months in orbit and 49 tests completed validating critical systems, components, and processes, we have successfully performed a controlled deorbit of Haven Demo, our in-space testbed for Haven-1 technologies. Read more. vastspace.com/updates/haven-…

As it turns out, “throw more surface area at it” is a viable strategy for the lack of air to carry waste heat away in orbit

@Robotbeat In all seriousness, I want to make some kind of device that runs off of solar and makes useful things when it has excess. Here in Oregon they don’t buy back any extra you send back to the grid which is super lame.

My 5 year plan includes producing (and storing) more solar power than I can use.

Some thoughts on destruction of oil and gas infrastructure in the Gulf. It is not exactly a new insight that modern economies operate on oil. Oil access, synthesis, and interdiction was a major theater of WW2. 100 years ago oil-poor nations spent heavily and participated in terrible wars over oil. See, for example, the Combined Bombing Offensive, Operation Tidal Wave, and the destruction of the Leuna synthetic fuel plants, not to mention the effectiveness of the submarine war in the waters around Japan. In 2022, energy producer Russia invaded Ukraine, instantly throwing into stark relief the idiocy of European energy policy, where an unholy alliance of heavily regulated energy contractors and astroturfed "green" activists managed to get Germany to shut down their nuclear industry. Even as solar panel production, largely initially developed and funded in the West, grew to overwhelming proportions, Europe insisted on sending roughly $1b *per day* to Russia for access to their oil and gas. If Europe had adjusted course in early 2022, then they would be able to support their power grids and probably some synthetic fuel production by now. The US built nuclear weapons from scratch in 2.5 years in the 1940s in competition with other national priorities at the same time. It's been more than four years since Ukraine's invasion. But no, they did sweet fuck all about ensuring energy sovereignty. Indeed, they even went in the other direction. Britain concentrated government resources on cracking down on free speech and stopped drilling for oil. The continent continued their ill-informed blanket ban on fracking, and working age people continued to pay the price, in the form of ever higher costs, ever higher taxes, ever poorer public services, ever dropping fertility. What about the rest of the oil importing developed world? France and Japan maintained their nuclear industry, their navies, their shipping industries and the fungibility of their supply - to an extent - even as they continued to actively burn up their economies in other more insidious ways. New Zealand shut down their last refinery. Australia exports a lot of crude and gas but mostly lacks the ability to close their supply chain in their own borders, and fuel prices have almost doubled. California continued to ban new drilling and continues to wage open regulatory warfare against their oil refineries, perversely increasing oil-related air pollution in the state from foreign oil tanker imports and pushing gasoline prices ever higher. More of the world has attempted to switch to natural gas supply, with investments exceeding $1t on gas import and export terminals, as though it's some fundamental law of nature that hydrocarbons must cross an ocean before they're used. As though the US fracking boom will last forever, or Asian demand growth won't see European prices continue to increase, further crushing their economic dynamism. I have been in the room with various Asian and European energy ministers and have asked them point blank: What's your plan? I have never gotten a better answer than a shrug, as though they'll muddle through and soon it'll be someone else's problem. The best time to get serious about domestic energy supply chains was four years ago. The second best time is today. The pain will ease just as soon as you say the magic words: I must increase my own energy supply! And yes, it is totally possible to produce synthetic oil and gas pretty much anywhere that people live with a solar-based process we've spent four years developing at @TerraformIndies, it is future proof, it is strategically robust, it is price-linked to solar manufacturing cost, which continues to fall like a rock. It's not entirely trivial to do but, given that Europe spends about 100,000x more on Russian oil and gas imports than they do on (privately funded) synthetic fuel development, I am on safe ground when I accuse Europe's leaders of committing gross capital misallocation. Imagine what the synthetic fuel industry could achieve with $1b/day! If you are an energy minister, now is a good time to reflect on fates worse than losing an election. Get back to work!

Yeah, as soon as Starship starts truly operating (I'll say that's when the first upper stage is reflown, maybe in 6-18 months?), things will rapidly get weird.

NEWS: NASA is planning a bigger @SpaceX Moon mission role using Starship, in a massive blow to Boeing. With the new proposal, Boeing's SLS would no longer be used to boost Orion close to the moon. Instead, Starship and Orion would dock in Earth orbit, giving Starship the pivotal role of propelling the capsule to the moon’s orbit, before taking astronauts down to the surface. bloomberg.com/news/articles/…

@bamboo_master_m Yeah, but only slowly. On the other hand: the gas giants have more helium than the mass of the entire Earth.

@Robotbeat the earth just keeps making helium. it is a renewable resource!
