In 1968 the Soviet Union launched two turtles into space. The most incredible thing is that the two came back to tell it

After the applause, whistles and the clinking of vodka bottles with which the night had started, silence now extends through the control center of Yevpatoria like a cold blizzard. The Soviet engineers, standing scattered in front of the monitors, can almost feel their icy, wet touch on their skin. All eyes are focused on the same person: Vasili Mishin, the chief designer who arrived from Baikonur to supervise the launch of the Soyud spacecraft of the Zond 5 mission. Sitting in front of the computers, Mishin does not take his penetrating eyes off the flashing lights on the panel. The Soyud which shortly before had successfully taken off towards the Moon (with a Proton rocket) from the Baikonur Cosmodrome in Kazakhstan, is having problems. And serious. With each clearing of Mishin’s throat, the silence in the Yevpatoria room becomes denser and denser. Although, like the rest of his comrades, Mishin had celebrated the takeoff of the Soyud ship in style, now beneath his thick, tangled eyebrows his pupils shine with a concentrated expression. History remembers him as “the loser in the race to the moon“, but that night he hits the nail on the head. Before the expectant gaze of his colleagues (and the distant but overwhelming tutelage of the Moscow leaders, immersed at that time in the space race with the United States), Mishin gives some precise and the ship 7K-L1 solves its first incident. The gyrfalcons of Moscow breathe a sigh of relief. Mishin’s brow relaxes. And at the Yevpatoria control center, bottles of vodka are being uncorked again. The celebration continues. Zond 5 at the time of being rescued. (POT) It is the night of September 14-15, 1968. Hundreds of meters above the heads of Mishin and the Yevpatoria engineers, 7k-L1 rises unstoppably towards the Moon. The journey of Zond 5 will go down in history for being the first probe to hit one turn around the satellite and return to Earth. An odyssey not without difficulties. The problem that the ship registered shortly after taking off from Kazakhstan would not be the only one on its eventful journey. Zond and his peculiar crew Zond 5 does not attract attention, however, due to the incidents it has had since its takeoff. He does it for the curious crew that was on board. The same one that would have perished in space if Mishin and the rest of the Yevpatoria team had not shown their cold blood. In order to check whether trips around the Moon could pose any problems for astronauts, the Soviets introduced Zond 5 capsule fruit flies, worms, plants, seeds, bacteria and… two turtlestwo copies of Testudo horsfieldii. In the pilot’s seat there was also a mannequin that emulated a Soviet astronaut: it was 1.75 meters tall and weighed 70 kilos. Space technicians had inserted sensors to monitor the levels of radiation to which he was exposed. A peculiar Noah’s Ark… With a rag and plastic Noah at the controls. Scientists with turtles in their hands. As Brian Harvey tells it in Soviet and Russian Lunar Explorationthe turtles had to face a journey worthy of Hollywood. On the way to the Moon, part of the mechanism contaminated and became unusable. During their return to Earth, another incident prevented the operation from proceeding as planned. The work that the Soviets had done left much to be desired: the sensor to locate the Earth was poorly mounted and the optics of the stellar sensors were blocked by the thermal insulation. On their return, the Chelonians had to endure a tremendous sway. The violent descent caused the outer shield of the ship (which weighed about 5,400 kilos) to reach very high temperatures. The capsule landed in the Indian Ocean on September 21, around seven in the afternoon. Their large parachutes were deployed to cushion the fall and beacons marked their location, not far from the Borovichy ship, who took it out of the water the next morning. From there he transferred to the cargo ship Viasili Golovin bound for Bombay, where he embarked on a Antono planev that took her back to the USSR. When they checked the interior of the ship, the technicians met the watery eyes of the pair of intrepid turtles who had flown around the Moon. They arrived before all of us. (Schorle/Wikipedia) Although their health was good, the turtles looked like two newcomers from the war: they had lost 10% of their body weight, they were starving (they had not eaten since days before takeoff, when they were placed in the capsule) and to make matters worse, it is said that one of them had hurt her eye. Not a bad balance if you take into account the stellar journey they had undergone. Their triumphant return after making a historic return to the Moon, however, did not help them save their lives. What the violent splashdown in the Indian Ocean had not done, scientists from the USSR did shortly after. After your first exam they sacrificed to perform an autopsy on them and study them in depth. The trip that had ended successfully. Zond 5 had been about 1,950 kilometers from the Moon and made a historic circumlunar journey. He also left impressive images for posterity. The Legacy of the Space Turtles The maneuvers of the Zond 5 mission generated excitement even outside Soviet borders. At the Jodrell Bank Observatory in Manchester, the famous radio astronomer Sir Bernard Lovell He tracked the ship. The English center would set off alarms by intercepting a message with a human voice that had its origins in Soviet ingenuity. Had the USSR managed to make a trip around the Moon piloted by an astronaut? In reality, what they were listening to was a recording to test transmissions in space. Among the voices they heard in Manchester was in fact that of the veteran Russian cosmonaut Valeri Bykovsky. On the pages of the book Animals in SpaceColin Burgess and Chris Dubbs point out that the voice was … Read more

the incredible secrecy with which the first iPhone was manufactured

What was it like working on the iPhone original? The question has surely been on the mind of every technology enthusiast: after all, we are talking about one of the greatest advances in technological consumption of the 21st century. And it is one that has an answer. It was given by Terry LambertApple engineer, a few years ago on Quora. Lambert was part of ‘Project Purple’, a top secret project in which it was only possible to work if one accepted not only endless days, but also an environment in which secrecy was absolute. So much so that Lambert had to sign a confidentiality agreement (NDA) not only to guarantee that he would not tell anything about that project: he signed it to be able to know the name of the key project. That was just the first of obsessive security measures who managed to protect that secret until the end. Lambert was responsible for about 6% (in number of lines) of the core code of OS The first thing he said is that when he was offered to work on that project, they took him to an area of ​​the headquarters where everyone dressed in black: that in itself was an unmistakable sign that something top secret was being worked on. Working blind, almost literally In fact, Lambert joked that if you wanted to create a cute Apple Halloween costume, all you had to do was put on a black sheet, cut out a couple of holes for the eyes, and go “secret project“. During that project he never saw the iPhone for which he was programming and debugging code: “I could only see the machine that did the remote debugging, not the actual device, but it was obviously a system based on ARM architecture.” After signing the NDA that allowed him to know the code name of the project – and of course he couldn’t discuss anything with anyone, including his family – he would end up working on something that he wasn’t even sure what it was, especially since Apple maintained completely independent groups in which they worked on small objectives that They did not allow us to know what they were working on on the whole. Another thing Apple does is give different code names for different groups. Or what is the same: you could be working on the same project as another person or group without knowing it. Neither debate it nor comment on it. Another engineer named Jerry Wang who also answered that question on Quora indicated how in fact he, who also worked on the documentation of that device and worked with the operators that launched the iPhone in the United States, did not know the project as ‘Project Purple’, but as ‘M68’. From that moment on he had access to a “secret laboratory” that was inside the main laboratory. Only a select few had access to that secret lab, but “you never got to see the design of the product, because when you’re doing that initial work, it’s all Plexiglas prototypes.” A curious detail: Lambert confessed how the cables used to “talk” to those pre-production units were, indeed, purple.

We do not know if Bill Gates is the owner of this incredible supereyate for sale. What we do know is its price: 645 million dollars

During the summer it is usual to see the richest 1% on the planet enjoy the sea and the sun aboard immense floating mansions in the form of supereyates that anchor near paradisiacal destinations such as Balearic coasts or the Caribbean islands. Bill Gates is not very given to boat walks, so It is not a regular of the covers of those supereyates. In fact, the founder of Microsoft has never recognized being the owner of one, as they have done Jeff Bezos, Mark ZuckerbergLarry Ellison and Even Amancio Ortega. However, that has not been an impediment to be attributed to the property of one of the most advanced and expensive supereies in the world: the Breakthroughthe first ecological supereate driven by a pile of hydrogen that now is put on sale for 645 million dollars. Bill Gates and a superyate that has never stepped on Since the Breakthrough He left the shipyard that manufacturer Feadship has near Amsterdam in October 2024, his name It has been linked To Bill Gates. That I tend into account that neither the millionaire nor the manufacturer have at any time confirmed his property, and the millionaire has never been seen walking through his covers, so there is no evidence that Bill Gates is really the owner of the owner of the Breakthrough. That said, it is easy to imagine the reason why it is linked to this floating palace with Microsoft’s founding millmillonarium. Its sale price less than a year ago was 645 million dollars, so the ship was limited to a few fortunes that could assume such cost, and its subsequent maintenance. On the other hand, Gates’s commitment to him Clean energy development and innovative projects could intuit that this innovative yacht could be one of the Sustainable initiatives of the tycoon. However, today, it is not possible to confirm that the Breakthrough Be one of Gates’ whims. Breakthrough The first driven by hydrogen Beyond its spectacular design and dimensions, the greatest challenge for Feadship was to develop the propulsion system of the Breakthrough. Instead of conventional diesel engineswho was known as PROJECT 821 It is based on a liquid hydrogen cell system stored at cryogenic temperatures below -253 degrees Celsius. This technology requires a lot of precision management and design to guarantee safety and efficiency due to high hydrogen volatility. The machine room stands out because, to accommodate the storage, conversion and hydrogen management systems, much more space is required than in conventional propulsion systems. The entire electrical system of the yacht, from the propulsion to the lighting and air conditioning of the ship, is feed on the electricity generated by this clean fuel, leaving water as the only residue. This type of system is a pioneer In the nautical sector and represents for many experts a real advance and a reference in terms of Innovation in maritime transportation. Jamie Edmiston, Executive Director of the Yates Management Company that has it for salehe said in a statement collectedby Fortune than the Breakthrough It is “the most extraordinary yacht ever built and the one that will change everything.” A floating palace in a sea of luxuries In addition to being the first to incorporate a quieter and more sustainable technology with the environment, the Breakthrough has not neglected the luxury and exuberance demanded by the users of this type of ships. This superyte It is 118.8 meters in length and 19 meters of manga (wide). It has 15 luxury cabins with capacity for up to 30 guests, and space to house the 44 crew that guarantee personalized attention 24 hours. According The published by Forbes Australiaamong its comforts are five covers on the flotation line and two more under it, communicated with an interior elevator that facilitates access. Another peculiarity is that from their helmet 14 balconies are displayed that leave a panoramic view from the cabins. The main cover on the bridge is basically an apartment with two bedrooms, two bathrooms, dressing rooms, private gym, pantry, two offices with chimney and living room. In addition, it is equipped with a complete hospital for medical emergencies, a library with selected collections, private cinema, pool and jacuzzi and fully equipped gym. The designers of the British Redman Whiteley Dixon study used a light neutral, marble, rattan, smoked eucalyptus wood and oak details to create a luxury atmosphere and exclusivity. All for the modest price of 645 million dollars.

What Spacex has achieved with Starship is incredible. The only problem is that he has done it at the expense of the health of his employees

Spacex has no paragon. The speed at which it assembles its rockets, the tests and itera in its design is far from the competition. But it comes with a hidden cost: a rate of injuries that multiplies by four of its rivals and reminds the security figures of 30 years ago. Context. Starbase is the Starship operations basethe place where the Aerospace Company of Elon Musk manufactures and proves the gigantic Rocket Starship with the ambition to launch thousands of ships to Mars in the coming decades. Although the program has achieved unthinkable technological feats, its frantic rhythm and its vertiginous deadlines are having a high human cost, especially if the risks assumed by Spacex are compared with the usual caution of the space industry. Six times more work accidents. Official data analyzed by Techcrunch They reveal that Starbase suffers six times more occupational accidents than the industry average, which makes it the rocket factory with the highest risk of injury in the United States. The Spacex headquarters registered a rate of injuries that multiplies by four of its rivals and resembles the figures of 30 years ago, when the security protocols were more lax. The figures are public. They leave The database of the United States Occupational Health and Safety Administration (OSHA) and use a standardized metric: the total rate of registrable incidents (TRIR), which calculates the number of injuries in one year per 100 full -time workers. Are public data that Spacex is obliged to report. And they are overwhelming. Starbase’s trir in 2023 was 5.9. That is, for every 100 employees, there were almost six recordable injuries. In comparison, the average of the space vehicle manufacturing sector was 0.7. And the average of the entire space sector was 1.6. A 30 -year setback. Although Starbase’s trir improved 4.27 in 2024, it is still a fact comparable to that of the sector 30 years ago. In 1994, the average trir was 4.2. In Starbase, with 2,690 employees in 2024, more than four injuries per 100 employees was 3,558 days of work with restrictions and 656 days of low labor. Anomalous even within Spacex. Starbase is not only a black point compared to the rest of the industry, but also within Spacex itself. None of the company’s facilities approaches the figures in southeastern Texas, with the exception of risky rocket recovery operations on the high seas (with a 7.6 trir). While Starbase registered 4.27 in 2024, the Falcon rocket factory in Hawthorne (California) recorded 1.43. A figure closer to that of competitors such as Blue Origin (a 1.09 in its Florida factory) or United Launch Alliance (1.12 in his Alabama factory). On the other hand, Starlink Terminal Factory in Bastrop registered 3.49, the Redmond satellit factory registered 2.89, the McGregor engines factory recorded a 2.48. Move fast and break things. Elon Musk’s philosophy works when applied to rockets, but squeaks when applied to the safety of his workers. What does Musk say? That the traditional media lie. Or at least that said when Reuters published that Spacex had not declared injuries that included amputations, crushed members and a death For a burst of wind that launched a worker from a truck. What does NASA say? NASA contracts with Spacex They include specific clauses that would allow the agency to intervene in case of a “serious security violation”, as a “repeated” sanction by the OSHA. The high trir rate, alone, is not enough to activate these clauses. Image | Spacex In Xataka | Starbase residents voted to be the city of Spacex. Now a letter has reached the right to their property

Within the most advanced chips manufacturing machines there is something incredible: small supernovae

Identifying a Supernova is an event that astronomers usually celebrate with enthusiasm. And it is not for less if we consider that they are One of the most violent events with which we can run into the cosmos. Knowing them better is very important because it can help us understand more precision How are the latest stages of The life of mass starsand also the mechanisms that explain how the material caused by stellar synthesis can lead to new star systems. The mathematical tools handled by astrophysics current nuclear fusion that take place in the nucleus of mass stars. During the stage known as the main sequence, stars obtain their energy from the fusion of hydrogen nuclei. As this chemical element is consumed, the star begins to produce helium nuclei, and, of course, its composition begins to evolve. During this process a huge amount of energy is released and the star is forced to continuously readjust to maintain hydrostatic balance, a phenomenon that is the result of the coexistence of two opposite forces capable of compensating. One of them is the gravitational contraction, which compresses the subject of the star, pressing it without rest. And the other is the radiation and gase pressure, which is the fruit of the ignition of the nuclear oven and tries to expand the star. The small supernovae of the extreme ultraviolet lithography equipment As we have anticipated from the holder, this article does not go only from Supernovas; It is also starred by the semiconductors. A priori we can intuit that these cosmic events and integrated circuits have nothing to do, but, curiously, they do have something in common. This is the reason why I found a good idea to start this text reviewing what a supernova is and why they occur. Otherwise we could not understand in all its extension the idea in which we are about to investigate. The ultraviolet radiation generation process used by UVE lithography equipment is very similar to what happens during a Supernova In the teams of extreme ultraviolet lithography (UVE) that manufactures the Dutch company ASML, high power lasers instantly heat tens of thousands of tiny tin drops in a single second until they reach a temperature of half a million Celsius degrees. This interaction produces An extremely hot plasma that emits ultraviolet light with a wavelength of 13.5 nm. This light must later be transported to the wafer thanks to a very precise mirrors and lenses system with the purpose of capturing the patterns that define the integrated circuits on a layer of photorers. Very broadly this is the strategy used by the most advanced semiconductor manufacturing machines that currently exist. And, as we have just seen, high -power lasers interpret an unquestionably protagonist role. As Jays Stewart, Chief of Research at ASML, explains in the very interesting article he has published in IEEE Spectrumthe ultraviolet radiation generation process used by UVE lithography equipment to produce avant -garde chips is very similar to what happens during a supernova. When a massive star exhausts its fuel and stops nuclear fusion processes, radiation pressure and gases is no longer able to counteract gravitational contraction. This phenomenon causes the star iron core It suddenly contracts under the enormous pressure that all layers of material that it has above. The star has lost the hydrostatic balance. At this moment all this matter loses the support that the nucleus exercised, which is now much more compact, and falls on it with enormous speed. When all that star material touches the surface of the nucleus there is a rebound effect that causes it to be fired with a huge energy towards the stellar medium, being disseminated. A supernova has just been produced. Some of them are so energetic that for a few seconds they emit more light than the entire galaxy that contains them. The tiny explosions that take place inside the UVE lithography equipment when a laser affects a tin drop produce a shock wave similar to that originating in the stellar medium, although much smaller scale. Surprisingly the mathematical equations that describe the evolution of these two types of explosions are the same. ASML engineers use them to calculate very precisely how the evolution of the shock wave that triggers plasma balls within the UVE equipment will be. And astrophysicians use them to describe the remains of the supernovas and deduce the properties of the star explosion that originated them. A Supernova has 10⁴⁵ times more energy That an explosion of tin, but thanks to this parallel, ASML engineers have been able to solve the complex problem derived from tin residues inside their most advanced lithography equipment.

The incredible Usha Vance dress with which Melania Trump has dazzled

The inauguration of Donald Trump As the 47th president of the United States, he has left countless images and anecdotes to remember, including the looks of two of the most anticipated guests. His wife and first lady, Melania Trump opted first for a striking hatwhich was much commented on, and which was later replaced by a two-tone dress and choker at the inaugural balls. Ivanka Trump, considered one of the most elegant women in the family, opted for a green design of marked inspiration royal which gave way to a dress that paid tribute to Audrey Hepburn. But one of the big surprises of yesterday was Usha Vance, wife of JD Vance, current vice president of the countrywho surprised with his choices for the events. © Getty Images A bespoke design by Oscar de la Renta The second lady of the United States knew that her outfits were going to be analyzed in detail and her choices did not go unnoticed even though, at first, all eyes were directed at the women of the Trump family. And if we had already said that Ivanka’s choice had certain similarities with the designs that Queen Letizia or the Princess of Wales usually wear at some of their most important events, Usha Vance’s, too. © Getty Images © Getty Images The American lawyer opted for a custom design created by Oscar de la Renta. It was a structured coat in a soft pink tone with a high collar and cinched waist with a belt that makes us think of the coat-dresses that conquer women time and time again. royals. Under this was a dress of the same tone, with a round neck, and also slightly fitted in the waist area. She completed the look with tall suede boots in a much paler pink that contrasted the color of the main garment. To finish the look, she carried a small handbag in a neutral tone and some striking floral earrings that were very visible thanks to the fact that her hair was tied up. © Getty Images A beaded dress for the inaugural balls It is a tradition that at nightfall, after the inauguration, we eat the traditional presidential dance. It is a moment of celebration in which attendees choose designs typical of any red carpet. That’s what they did not only Melania and Ivanka Trump with her designs with black and white as protagonistsalso Usha Vance who opted for a dress studded with rhinestones and created by one of the most internationally recognized bridal and guest brands: Reem Acra. © Getty Images © Getty Images The Lebanese designer launched her eponymous brand in 1997 and has since become a reference in bridal fashion, dressing celebrities such as Jennifer Lopez, Taylor Swift and Halle Berry on red carpets and important events. That is why we are not surprised that, for an event of such magnitude, the second lady opted for one of her creations. Specifically, it deals with a gala design that was part of its Pre Fall 2024 collectiona semi-transparent chiffon dress, embroidered with paillettes and sequins and in a shade of blue that is known by the nickname of blue royalsince it is one of the colors that most frequently sneaks into the choices of royal women. This garment, with a false strapless neckline, has a corseted bodice and an A-line skirt that extends to the floor. © Getty Images The story of Usha and JD Vance Usha made history this Monday by becoming the first indian american second lady. She and the vice president, who They met at Law School.they have been married since 2014 and boast a solid marriage. It was during the 2024 Republican National convention that he said JD Vance was “the most determined person I’ve ever met, with one overriding ambition: to become a husband and father and build the kind of close-knit family he had longed for as a child. My background is very different from JD’s. I grew up in San Diego, in a middle-class community with two loving parents, both immigrants from India, and a wonderful sister. The fact that JD and I were able to meet, fall in love, and get married is a testament to this great country. It is also a testament to JD. And it tells you something about who he is.”
