mechatronics and the hydrogen line: 14may26

Politics in Britain has returned to high psychodrama, the kind you normally find in failing states.

Just noticed I haven’t set the date window on this watch! 8C with a feels-like of 4C, which explains the pain in my hands and wrists this morning, and the sky to the east has turned black.

Today I learned “mechatronics” is an actual word:

Just a few hours before the Orion spacecraft crossed the sky en route to the moon on April 1, mechatronics engineer Rodrigo Trevisan Okamoto received confirmation he had been waiting for since the Artemis 2 mission was announced in 2023. The email from NASA stated that the crew of the first crewed mission to orbit the moon in half a century would carry a device developed by Okamoto and his team at Condor Instruments, a São Paulo-based startup.

“The NASA announcement was sudden and caught us by surprise. And it was only after the mission concluded that we learned the astronauts had been using the equipment in tests for the past two years,” Okamoto told Agência FAPESP.

The device, called an actigraph, is shaped like a wristwatch and incorporates accelerometers, as well as light and temperature sensors, to precisely map the user’s sleep and wake patterns over the course of days or weeks.

In 1959, physicists Giuseppe Cocconi and Philip Morrison, colleagues at Cornell University, published “Searching for Interstellar Communications” in Nature as part of the emerging field of SETI—the Search for Extraterrestrial Intelligence.3 Recognizing the spin-flip resonance frequency of hydrogen and noting the ubiquity of the element throughout the cosmos, they deduced that other technologically advanced civilizations would similarly attempt to transmit messages on what they termed “the hydrogen line.” In effect, the scientists had identified a pre-civilizational cosmic commons: the hydrogen envelope enshrouding the Big Bang’s host of celestial bodies, cosmic detritus, and all potentially existing lifeforms beyond planet Earth—an open field for interstellar communication held in common before any civilization arrived to claim it.

The 1420 MHz band is now protected by international convention, reserved strictly for the reception of potential transmissions and restricted from commercial or terrestrial use. The hydrogen line is thus shuttered to the appropriations of what Bataille terms “the restricted economy.”4 In our secular scientific world, the hydrogen line serves as the part of the frequency spectrum humanity holds open for contact with inhuman realms…

You notice the anxious darting of his eyes, then the makeup: thick, chalky concealer layered over skin that looks irritated, acne ridden and painful underneath it. His content team trails him carrying bright portable lights, but he doesn’t speak to them like a boss or even a collaborator. He speaks to them like an insecure thirteen-year-old midway through a panic attack: rapid little bursts about how the angle is wrong, how his skin looks bad, how he’s not even talking to the right people.

Within thirty minutes he’s completely withdrawn, sitting alone at the edge of a banquet, scrolling on his phone. Every few seconds his face twitches slightly, tiny repetitive tics perhaps a side effect of the chemical cocktail he’s on.

I had no desire to speak to him. I watched several girls try, only for Clavicular to speak about them while they were still standing there, openly complaining to his entourage that the interactions weren’t interesting enough to clip into content.

Before I leave I glance over Clavicular’s shoulder to see what he’s scrolling on.

No surprise: himself.

He flips between platforms checking views with total concentration, pausing at different uploads like a trader monitoring stock performance.

STATUS: spring is apparently on pause, and this week has turned into a cluster – lost yesterday to plumbing issues that cost me five hundred quid, the day after I said, we’ve got a little money, let’s go out to that very expensive restaurant on Friday…

At dawn, he walked a short distance to a stream to wash. He had just knelt to splash water on his face when a tremendous blast of hot air flattened him among the rocks. When he recovered his senses, staring upwards, he saw the afterburners of two Israeli F-4 Phantom jets disappearing into the sky and, very close to him, a small green lizard that he would remember for the rest of his life. Apart from cuts and bruises, a bloodied forehead and singed hair, Ekberg was unhurt. As he staggered back, unable to hear anything other than the ringing in his ears, he saw men running and gesticulating, a severed leg on the ground, what looked like entrails caught on tree branches. Fires were burning among the trees and the air smelt of roast meat, cordite and faeces.

I hate these “recalibration” weeks where I have to reset routines, intents and diet back to zero.

Headline: Scientists Say They’ve Figured Out a Way to Get to Alpha Centauri in Just 20 Years. Actuality: it’s laser propulsion again, and it currently only works at the microscopic level. Takes me back to the days of Leik Myrabo and his “lightcraft” laser launch system, which didn’t scale up beyond the size of a coaster and got seventy metres up before they fell off the laser or melted.

The actual paper coins the term “metajets,” which I like.

sailing ship time: 26mar26

Off to see PROJECT HAIL MARY today, and then I need to crack a story idea that’s been eluding me for two weeks, and tomorrow is solid scripting and prose writing all damn day, and then the weekend is all about washing out propagators and starting seeds. It’s going to be a cold weekend, and the light and spring warmth is supposed to come back next week… and I’m back to living in the weather changes. I suspect I’ll be losing an entire day next week to running the woodchipper and chopping holly wood into logs, in between planting raspberry canes and onions.

I missed this yesterday: NASA intends to send a probe to Mars on top of a nuclear-electric drive, Space Reactor-1 Freedom. It seems to be pretty much a test article – a year-long transit to Mars does not imply much in the way of breakthrough oomph, but the efficiency of nuclear-electric thrust does mean that once it’s dropped off its payload of helicopters at Mars there will be more than enough juice to send the thing off to Saturn.

Important to remember that this is nuclear-electric, not nuclear-thermal – therefore slower but “cleaner.” I don’t yet know enough to know if a bigger reactor will provide more nuclear-electric speed, so we’re still in sailing-ship transit times. I always thought I’d see a solved version of NERVA in my lifetime, but I guess not.

moonbase: 25mar26

I noticed yesterday that NASA announced “President Trump’s Moon Base” will be commenced before the end of 2028, therefore the end of the President’s term. Given that the delayed Artemis 2 mission is a lunar flyby and Artemis 3 was reconfigured from a lunar landing to a low earth orbit test of new spacesuits and the dock/undock of a lander – and note that Apollo did those missions the other way around, Apollo 7 crew-rated the boat and lander configuration in LEO, Apollo 8 was the lunar flyby – this may get a little scary/deathy. Twenty-five launches between now and the end of 2028, ten lunar launches next year alone, is a hell of a swing.

I took this ten minutes before the HAIL started.

Absolutely dismal day out there, with a “feels like” of -4 C and 40mph winds. The mancub has made it clear that he blames me – he hates the wind, and is punishing me for taking the sun away. For some reason, he made the very specific decision, not long after we got him, that the weather is always my fault.

content break: 23mar26

Spring is surging out there in the world. A few little flashes of cold, then some rushes of warmth. I have some big pots and extra compost arriving over the next couple of days. Bot traffic is expected to exceed human traffic on the internet by 2027, and, frankly, I can already tell. I note that The Economist is now referring to the current mess in the Middle East as The Third Gulf War, a term that has a bit of a chill on it. A review of two dozen clinical trials suggests that the supposed magic fix for depression through use of psychedelics seems to be mostly down to the placebo effect. Freeze-dried elflord Bryan Johnson is livestreaming himself smoking toad pus. One study suggests that 20% of more than 14,000 books self-published through Amazon are mostly written by AI. However, something like 3.5 million books were self-published last year, and they obviously couldn’t all be checked by that study. When the net tells you to go back out into the world, you should probably listen.

That’s the main notebook – insert 1 is the daily book, the two behind it are what I run LTD and Orbital Operations off.

It may be meteorological spring, but it’s grey and misty out there, so I’m today using the midwinter beard oil I was gifted by Fires of Freyja.

Low energy slobby day: black Wrangler jeans that are now four inches too big for me, black Wrangler workshirt, surplus Russian submariners base layer which I like for its boat neck, an old grey Calvin Klein jacket, and a grey cashmere scarf because I have reached the age where I must take the scarf.

Two months ago, a key staffer for Sen. Ted Cruz said in a public meeting that she was “begging” NASA to release a document that would kick off the second round of a competition among private companies to develop replacements for the International Space Station.

There has been no movement since then, as NASA has yet to release this “request for proposals.” So this week, Cruz stepped up the pressure on the space agency with a NASA Authorization bill that passed his committee on Wednesday.

Regarding NASA’s support for the development of commercial space stations, the bill mandates the following, within specified periods, of passage of the law:

  • Within 60 days, publicly release the requirements for commercial space stations in low-Earth orbit
  • Within 90 days, release the final “request for proposals” to solicit industry responses
  • Within 180 days, enter into contracts with “two or more” commercial providers for such stations

Cruz is trying to inject urgency into NASA as several private companies—including Axiom Space, Blue Origin, Vast, and Voyager—are finalizing designs for space stations. All have expressed a desire for clarity from NASA on how long the space agency would like its astronauts to stay on board, the types of scientific equipment needed, and much more. These are known as “requirements” in NASA parlance.

When NASA Administrator Jared Isaacman announced the revamped approach to the Artemis moon program, it was unclear whether the new mobile launcher that has been constructed over the last two years at Kennedy Space Center would ever get used.

A NASA rundown of the reconfigured Artemis launch plans released Tuesday, though, answers that question for the foreseeable future: No.

“The agency is no longer planning to use the Exploration Upper Stage or Mobile Launcher 2, as development of both has faced delays,” according to the agency update.

The universe is overrun with dark matter, outweighing the ordinary stuff that stars and planets are made of five-to-one. But some corners of the cosmos are more dominated by the invisible substance than others.

Using the stalwart Hubble Space Telescope, a team of astronomers have found a galaxy 300 million light away that appears to be made of at least 99.9 percent dark matter — so much that the galaxy is barely visible at all, they report in a new study published in The Astrophysical Journal Letters.

The tenebrous realm, dubbed CDG-2, could be one of the most dark matter heavy galaxies ever found, and a compelling candidate for elusive and yet hypothetical “dark galaxies” that astronomers have been searching for for decades, which are thought to contain vanishingly few, if any, stars.

hung up: 24feb26

Woke up, hung out with the mancub a bit, sat outside with coffee reading the news, ate berries and honey, did a couple of pages on the laptop, walked up to the coffee shop, worked in the notebook over a couple of double espressos, had a chat with the Italian ice cream man who lives at the top of the road. I feel like 90% of myself at this point, and like my 2026 has finally gotten started.

Yesterday I reduced a viburnum by half, hacked back salvia and holly, raked a bed, dug a trench in it, mixed a hundred litres of compost into the trench, and planted three cherry trees. Today I am actually less achy and knackered than I expected, especially bearing in mind that I still have this plague in my system. Once I have some charge in my phone, I’m going to check the weather and see if I’m going to have the space to plant some apple trees today.

Today it’s the Swatch Metropolis, yesterday it was the G-Shock G-Rescue because it was a day of working with saws and chainsaws and other implements of destruction.

New newsletter is out.

Shoplifter, “Chromo Sapiens” (2019).

Taking off the Fitbit and the Apple Watch, putting on the Maven watch, setting up the third stage of the new notebook system (with a fourth stage to come) – it’s rapid disconnection time. More on that tomorrow because I’ve just been told I’m apparently going out for lunch.

It can be no coincidence that the hierarchical, anti-democratic Spartans, who privileged military might above all else, prided themselves on the pithiness of their speech. According to Plutarch, when an Attic orator accused the Spartans of being ignorant, Pleistoanax, the Spartan king (r. 458-409 BCE), replied: “What you say is true. Of all the Greeks, we alone have not learnt your evil ways.”
