    Poiché i componenti risalgono agli anni Ottanta, queste tute sono spesso più “vecchie” degli astronauti che le indossano e hanno ampiamente superato la vita operativa prevista, manifestando pericolosi malfunzionamenti, come le perdite d’acqua nel casco che nel 2013 hanno fatto rischiare la vita a Luca Parmitano.

    La EMU americana, progettata per l'era dello Space Shuttle, è un sistema modulare costruito originariamente in 18 unità fino al 1982. Non è mai stata sostituita da modelli più recenti. Oggi sulla ISS ne restano operative solo quattro unità, soggette a manutenzione da parte di Collins Aerospace.

    A differenza della EMU, la Orlan utilizza un design monoblocco a ingresso posteriore: lo zaino posteriore funge da sportello, permettendo all'astronauta di vestirsi autonomamente in pochi minuti, mentre la EMU richiede assistenza. Un’altra importante differenza tra i due progetti è questa: la EMU è modulare e si adatta alle misure dei vari astronauti con pezzi di diverse taglie, mentre la Orlan è "taglia unica" e viene regolata tramite un sistema di pulegge e cavi interni.

    Sia le tute EMU sia le tute Orlan sono state concepite originariamente negli anni Settanta, ma hanno avuto due percorsi molto diversi.

    Dalla loro prima versione del 1977 a oggi le tute russe Orlan sono state aggiornate più volte. L’attuale versione Orlan-MKS, introdotta nel 2017, è stata migliorata nel controllo termico e nei materiali.

    Le tute spaziali sono così pesanti perché non sono semplici indumenti, ma veri veicoli spaziali monoposto. Forniscono ossigeno, eliminano l'anidride carbonica e proteggono dalle temperature estreme. Contengono riserve d'acqua potabile e sistemi radio per le comunicazioni. Proteggono inoltre dai micrometeoriti, che viaggiano a velocità molto superiori a quelle dei proiettili di arma da fuoco, e dalla luce solare diretta con le loro particolari visiere dorate.

    Sulla Stazione Spaziale Internazionale (ISS) si usano attualmente due tipi di tute per attività extraveicolari: l’americana Extravehicular Mobility Unit (EMU) e la russa Orlan-MKS. La prima ha una massa complessiva di circa 140 kg, la seconda di circa 110 kg. In microgravità, gli astronauti non ne percepiscono il peso, ma ne avvertono l’inerzia ogni volta che devono iniziare un movimento, fermarsi o cambiare direzione.

    « L’importance de la souveraineté numérique doit aussi être assumée sur le plan symbolique. Par exemple, les dirigeants politiques devraient cesser de faire transiter leurs messages par des plateformes qui sont gérées selon des normes éloignées des valeurs québécoises, comme la plateforme X […] les citoyens québécois devraient être invités à migrer vers des réseaux sociaux contrôlés ici qui commencent à émerger, comme le réseau social Qlub. » @pierretrudel dans @ledevoirhttps://www.ledevoir.com/opinion/chroniques/964287/enfin-plan-souverainete-numerique

    Fictional Moon: Reality TV and SciFi Don’t Mix

    Fictional Moon: Reality TV and SciFi Don’t MixIt is a safe bet that nearly all Hackaday readers like to at least imagine what it would be like to build and live in an orbital station, on the moon, or on another planet. Moon bases and colonies show up all the time in fictional writing and movies, too. For the Hackaday crowd, some of these are plausible, and others are — well — a bit fanciful. However, there’s one fictional moonbase that we think might have been too realistic: Moonbase 3.View of the base from above.If that didn’t ring a bell, we aren’t surprised. The six-episode series was a co-production between Twentieth Century Fox and the BBC that aired in 1973. To make matters worse, after the initial airings in the UK, Australia, and New Zealand, the video master tapes were wiped out. Until 1993, there were no known copies of the show, but then one turned up in a US television station.The show had many links to Dr. Who and, in fact, if you think the spacesuits look familiar, they made later appearances in two Dr. Who episodes.These spacesuits would later show up in Dr. Who.Consider the year 1973. Four years earlier, the US went to the moon after essentially starting from scratch ten years earlier. The show was set in the far future of 2003, so it is easy to imagine that a lot would happen in the next 30 years. Sadly, that wasn’t the case, but you can hardly blame the writers.The premise was that there were five moonbases, each with a number. The US and Russia had Moonbases 1 and 2. The Europeans had the titular Moonbase 3. China and Brazil had the final two moonbases.The goal of the Moonbase was to conduct scientific research on materials such as foamed metals and exotic fuels. Of the six episodes, the final one is amazing and redeems the rest of the series. However, overall, the show is competent but nothing special. However, as I mentioned, it is almost too realistic.The RealismThe show had a real science advisor, BBC science correspondent [James Burke], later of “Connections” fame, so things looked mostly good. The NASA-like chatter is realistic, and they talk about computers using nouns and verbs like the Apollo computers, but which didn’t turn out to be especially accurate in the far future of 2003. The producers’ aim was to make a realistic program and stay away from “bug-eyed monsters.” It is true, though, that one episode at least hinted at monsters, but, in the end, it turned out to be a false alarm.The tech isn’t amazingly realistic, but none of it is just crazy fantasy either. But the true realism — and the part that might have prevented it from being a big hit like Star Trek or Dr. Who — was the story content itself.Another day at the (lunar) office.Most of the stories show people in slightly futuristic-looking offices talking about how to maintain their funding from Earth. If you’ve ever worked on a government project, you know this is probably the most realistic thing you could do on a show like this. It is also tedious and boring.Sure, there are stories about psychological stress, accidents (which, of course, threaten funding), and erratic scientists. There’s a Mr. Scott-like engineer who needs rescuing by a Russian — heady stuff for 1973. But the thread through it all is worrying about budget cuts or a shutdown order.That said, none of the episodes are especially bad, either. The first episode, “Departure and Arrival,” has the old director leaving and a new director arriving, which makes it handy to introduce everyone to the audience. The other episodes were filmed in a different order than the airing order, so it doesn’t hurt much to skip around, but we’d suggest saving the last episode for last.We don’t write TV dramas, but we imagine the same could be said of most genres. If you made a realistic show about the police force, the fire department, and a hospital emergency room, too much realism would probably be a real drag. No one wants to see the department have mandatory safety training or check hoses for defects. There might be some excitement, but the ratio of excitement to mundanity is probably pretty lopsided toward the boring.Some of what the show predicted came true: Russia and the US would cooperate in space. The moon did have ice. But like most shows of its era, it missed the boat on things like personal communication, flat screens, and other modern tech.UnrealisticNot that it is all realistic. For some reason, the low gravity on the moon is only apparent outside the Moonbase, but there doesn’t seem to be any artificial gravity. The model work leaves something to be desired, and while you can excuse it as quaint, other shows of the same time or earlier did better.To build drama, the characters had to make mistakes. A lot of them. “Oh! I ran out of oxygen!” “Drat! My spaceship was throwing an error, but it fixed itself, and now it’s back!” Things like that. It is hard to imagine that, given the hostile environment and the cost of a base like this, the people would be so careless.The final episode features a scientific project that’s hard to imagine, but I won’t say more because I don’t want to spoil the best episode.Of course, there are plenty of technical errors if you consider what really happened in 2003, but you can forgive those.Your FavoriteI don’t mean to pan the show. You should hang in there for episode six. I don’t recommend skipping right to it, either. It may not become your favorite moonbase, but the show is highly watchable. You can find a few copies of the entire series on YouTube. There are also a few copies on Archive.org.What’s your favorite fictional moonbase? We wish some of the planned moonbases had become real, but alas, they, too, were fictions. While not a moonbase, the Great Moon Hoax was fictional, even though it claimed to be factual.hackaday.com/2026/03/17/fictio…
