The hits just keep coming for the International Space Station (ISS), literally in the case of a resupply mission scheduled for June that is now scrubbed thanks to a heavy equipment incident that damaged the cargo spacecraft. The shipping container for the Cygnus automated cargo ship NG-22 apparently picked up some damage in transit from Northrop Grumman’s Redondo Beach plant in Los Angeles to Florida. Engineers inspected the Cygnus and found that whatever had damaged the container had also damaged the spacecraft, leading to the June mission’s scrub.

Mission controllers are hopeful that NG-22 can be patched up enough for a future resupply mission, but that doesn’t help the ISS right now, which is said to be running low on consumables. To fix that, the next scheduled resupply mission, a SpaceX Cargo Dragon slated for an April launch, will be modified to include more food and consumables for the ISS crew. That’s great, but it might raise another problem: garbage. Unlike the reusable Cargo Dragons, the Cygnus cargo modules are expendable, which makes them a great way to dispose of the trash produced by the ISS crew since everything just burns up on reentry. The earliest a Cygnus is scheduled to dock at the ISS again is sometime in this autumn, meaning it might be a long, stinky summer for the crew.

By now you’ve probably heard the news that genetic testing company 23andMe has filed for bankruptcy. The company spent years hawking their spit-in-a-tube testing kits, which after DNA sequence analysis returned a report revealing all your genetic secrets. This led to a lot of DNA surprises, like finding a whole mess of half-siblings, learning that your kid isn’t really related to you, and even catching an alleged murderer. But now that a bankruptcy judge has given permission for the company to sell that treasure trove of genetic data to the highest bidder, there’s a mad rush of 23andMe customers to delete their data. It’s supposed to be as easy as signing into your account and clicking a few buttons to delete your data permanently, with the option to have any preserved samples destroyed as well. Color us skeptical, though, that the company would willingly allow its single most valuable asset to be drained. Indeed, there were reports of the 23andMe website crashing on Monday, probably simply because of the rush of deletion requests, but then again, maybe not.

It may not have been 121 gigawatts-worth, but the tiny sample of plutonium that a hapless Sydney “science nerd” procured may be enough to earn him some jail time. Emmanuel Lidden, 24, pleaded guilty to violations of Australia’s nuclear proliferation laws after ordering a small sample of the metal from a US supplier, as part of his laudable bid to collect a sample of every element in the periodic table. Shipping plutonium to Australia is apparently a big no-no, but not so much that the border force officials who initially seized the shipment didn’t return some of the material to Lidden. Someone must have realized they made a mistake, judging by the outsized response to re-seize the material, which included shutting down the street where his parents live and a lot of people milling about in hazmat suits. We Googled around very briefly for plutonium samples for sale, which is just another in a long list of searches since joining Hackaday that no doubt lands us on a list, and found this small chunk of trinitite encased in an acrylic cube for $100. We really hope this isn’t what the Australian authorities got so exercised about that Lidden now faces ten years in prison. That would be really embarrassing.

And finally, we couldn’t begin to tote up the many happy hours of our youth spent building plastic models. New model day was always the best day, and although it’s been a while since we’ve indulged, we’d really get a kick out of building models of some of the cars we had an emotional connection to, like the 1972 Volkswagen Beetle that took us on many high school adventures, or our beloved 1986 Toyota 4×4 pickup with the amazing 22R engine. Sadly, those always seemed to be vehicles that wouldn’t appeal to a broad enough market to make it worth a model company’s while to mass-produce. But if you’re lucky, the car of your dreams might just be available as a download thanks to the work of Andrey Bezrodny, who has created quite a collection of 3D models of off-beat and quirky vehicles. Most of the files are pretty reasonably priced considering the work that obviously went into them, and all you have to do is download the files and print them up. It’s not quite the same experience as taking the shrink-wrap off a Revell or Monogram box and freeing the plastic parts from they’re trees to glue them together, but it still looks like a lot of fun.

What a long, strange trip it’s been for NASA astronauts Suni Williams and Bruce Wilmore, who finally completed their eight-day jaunt to space after 289 days. The duo returned to Earth from the ISS on Tuesday along with two other returning astronauts in a picture-perfect splashdown, complete with a dolphin-welcoming committee. For the benefit of those living under rocks these past nine months, Williams and Wilmore slipped the surly bonds way back in June on the first crewed test flight of the Boeing Starliner, bound for a short stay on the ISS before a planned return in the same spacecraft. Alas, all did not go to plan as their ride developed some mechanical difficulties on the way upstairs, and so rather than risk their lives on a return in a questionable capsule, NASA had them cool their heels for a couple of months while Starliner headed home without them.

There’s been a lot of talk about how Butch and Suni were “stranded,” but that doesn’t seem fair to us. Sure, their stay on the ISS was unplanned, or at least it wasn’t Plan A; we’re sure this is always a contingency NASA allows for when planning missions. Also unfortunate is the fact that they didn’t get paid overtime for the stay, not that you’d expect they would. But on the other hand, if you’re going to get stuck on a work trip, it might as well be at the world’s most exclusive and expensive resort.

Speaking of space, while it’s statistically unlikely that anyone reading this will ever get there, you can still get a little taste of what space travel is like if you’re willing to give up ten days of your life to lie in a waterbed. What’s more, the European Space Agency will pay you 5,000 euros to do it. The experiment is part of the ESA’s Vivaldi III campaign, an exploration of the effects of extended spaceflight on the human body. The “waterbed” thing is a little misleading, though; since the setup is designed to simulate the posture the body takes in microgravity, they use a tank of water (heated, we hope) with a waterproof cover to submerge volunteers up to their torso. This neutral body posture looks pretty comfortable if you’re sleeping in space, but we tend to think it’d get annoying pretty quickly down here. Especially for potty breaks, which aren’t done astronaut-style but rather by being transferred to a trolley which lets you do your business without breaking from the neutral posture. Still, 5,000 euros is 5,000 euros.

Bad news for the meme-making community, as it appears AI might be coming for you, too. A recent study found that LLMs like ChatGPT can meme better than humans, at least under certain conditions. To come to that conclusion, researchers used some pretty dank meme templates and pitted humans against ChatGPT-4o to come up with meme-worthy captions. They also had a different group of humans collaborate with the LLM to come up with meme captions, which for practical purposes probably means the humans let the chatbot do the heavy lifting and just filtered out the real stinkers. When they showed the memes to crowdsourced participants to rate them on humor, creativity, and shareability, they found that the LLM consistently produced memes that scored higher across all three categories. This makes sense when you think about it; the whole job of an LLM is to look at a bunch of words and come up with a consensus on what the next word should be. Happily, the funniest memes were written by humans, and the human-LLM collaborations were judged more creative and shareable. So we’ve got that going for us, which is good.

We noted the passing of quite a few surplus electronics shops in this space before, and the closing of each of them, understandable as they may, marks the end of an era. But we recently learned about one surplus outfit that’s still going strong. Best Electronics, which specializes in Atari retrocomputing, has been going strong for over 40 years, a neat trick when Atari itself went bankrupt over 30 years ago. While they appear to have a lot of new old stock bits and bobs — they’re said to have acquired “thousands and thousands” of pallets of Atari goods from their Sunnyvale warehouse when the company folded — they also claim to spend a lot of money on engineering development. Their online presence is delightfully Web 1.0, making it pretty hard to sort through, but we think that development is mainly upgraded PCBs for things like joysticks and keyboards. Whatever they’re doing, they should just keep on doing it.

And finally, have you ever seen a knitted breadboard? Now you have, and while it’s of no practical value, we still love it. Alanna Okun made it for the ITP Stupid Hackathon at NYU back in February. There aren’t any instructions or build docs, so it’s not clear how it works, but from the photos we’d guess there’s either conductive yarn or solid copper wire knitted into the pattern to serve as bus bars.

It’s been a busy week in space news, and very little of it was good. We’ll start with the one winner of the week, Firefly’s Blue Ghost Mission 1, which landed successfully on the Moon’s surface on March 2. The lander is part of NASA’s Commercial Lunar Payload Services program and carries ten scientific payloads, including a GPS/GNSS receiver that successfully tracked signals from Earth-orbiting satellites. All of the scientific payloads have completed their missions, which is good because the lander isn’t designed to withstand the long, cold lunar night only a few days away. The landing makes Firefly the first commercial outfit to successfully soft-land something on the Moon, and being the first at anything is always a big deal.

Slightly less impressive was Intuitive Machines’ attempt at a landing a day later. Their NOVA-C robotic lander Athena managed a somewhat controlled landing, but the spacecraft is lying on its side rather than upright, a surprisingly common failure mode for recent lunar landings. Also in the failure category is the loss of the world’s first private asteroid mining mission, as well as SpaceX Starship test flight 8, which ended in spectacular fashion this week as Starship exploded soon after booster separation. As usual, Scott Manley has the best analysis of the incident, which seemed to involve a fire in the engine bay that led to a rapid loss of thrust from four of its six engines, and sent the spacecraft tumbling before tearing itself apart. The only good news from the flight was the third successful catch of the returning booster by the chopsticks, which just never gets old.

What does get old is stories about printer manufacturers and their anti-consumer hijinks, especially when it involves one of the only manufacturers who wasn’t playing the “buy our consumables or we brick it” game. In addition to just about every other printer maker, Brother now stands accused of sending firmware up to printers that turns off functionality if non-OEM cartridges are used. The accusations come from Louis Rossman, well-known for his right-to-repair advocacy and, ironically, long-time proponent of Brother printers as least likely to be bricked. His accusation that “Brother is now among the rest of them” is based on a pretty small sample of affected users, and a self-selected one at that, so take that with the requisite amount of salt. For their part, Brother denies the claim, stating simply that “Brother firmware updates do not block the use of third-party ink in our machines.” They don’t go much beyond that by way of an explanation of what’s happening to the users reporting problems other than to say that the users may be confused by the fact that “we like to troubleshoot with Brother Genuine supplies.” What the real story is is anyone’s guess at this point, and the best advice we can offer is either to avoid printers altogether, or just buy the cheapest one you can get and harvest it for parts once the starter cartridges are empty.

If like us you’ve accumulated a large collection of physical media films and TV shows to while away the long dark days of a post-apocalyptic nightmare where Netflix and Hulu are but a distant memory, you might want to rethink your strategy. Some DVD aficionados have found a troubling trend with “DVD rot,” especially with discs manufactured by Warner Brothers Discovery between 2006 and 2008. It’s not clear what’s going on, but it looks like the polycarbonate cover is delaminating from the inner Mylar layer, resulting in cloudy areas that obscure the data. Warner is aware of the problem and will replace defective discs with the same title if possible, or exchange it for a title of like value if the original is no longer available. We’re dismayed that this defect probably includes our beloved Looney Tunes collection, but on the upside, now we have an excuse to sit through forty straight hours of cartoons.

And finally, if you were a NASA rocket engineer in the 1960s, skipping leg day wasn’t an option. That’s because the Saturn V full-stack shake test on the Apollo program was a very hands-on feet-on process. The shake test was performed to make sure nothing was loose on the stack, and that it would be able to withstand not only the shaking induced by those five massive F-1 engines, but also the occasional hurricane that Florida is famous for. To get the rocket shaking, engineers sat on the deck of the gantry with their legs bridging the gap and their feet up against the side of the service module and gave it all they had. Other engineers literally backed them up, to provide something to push against, while another team on the uppermost platform used a rope to play tug-of-war with the command module. They were able to get the stack moving pretty good, with a meter or so of deflection at the escape tower. It does raise the question, though: what would they have done if the test failed?
