There is nothing to make blue in blue eyes. If we want to understand why, we have to resort to physics

by

Many of us learned first genetics lessons through peas and eye color. But there is more science when Explain the color that acquire our eyes. Not only does physics intervene but also a somewhat more complex biology than we believed in the beginning. Nature and blue. The blue color It is not one of the most frequent In nature. Perhaps that is why exceptions such as the flowers of this color, the plumages of some birds or the wings of certain insects are striking. A reason is in the optimization of resources. Blue pigments are molecules that reflect light in certain segments of the electromagnetic spectrum, those of blue tones, giving color to an object. The problem with these molecules is that They usually have a large size. This makes them difficult to synthesize by living beings so, if they do not offer a significant evolutionary advantage, they will not be created by our body. It is not chemical, it is physical. That is why when we see the blue color in nature, it is likely that its origin is not in a chemical compound but in some physical phenomenon. This is what happens, for example, in the case of the plumage of some birds, whose origin is in nanostructures whose shape is responsible for reflecting the light in short lengths of the visible spectrum, those of blue color. And it is also the case with blue eyes. Absence of pigmentation. Only that in the case of blue eyes it is not about the nanostructures but of the iris and of the Tyndall effectan effect similar to the person responsible for seeing the blue sky (and the red sunsets), Explain in an article in The conversation Davinia Beaver, expert in regenerative medicine of the Bond University, in Australia. When the light enters our eye, the suspended particles found in it interact with the shortest spectrum lengths, causing them to disseminate more, “bouncing” thus part of the blue color of the waves outside. The brown, quite the opposite. This effect does not occur among people with brown eyes because there is a pigment in this. This “catch” part of the light causing it not to escape so easily from the eye, giving darker tones. The pigment in question: melaninthe same responsible for darker skin tones. There are more eyes colors, such as green or “hazelnut color” eyes. These colors can be seen as the combination of the dispersion of the light of the Tyndall effect, modulated by a certain presence of melanin, either in small quantities or concentrated in some regions of the iris. Genetics is not so simple. The genetics we study in our school stage, of course, is simple, a simplified version of what we know about this field of biology. A field, in addition, that has been advancing over time, becoming more complex as we detract more and more details about its operation, Beaver remembers. Point out, for example, there are several genes that affect the appearance of our eyes, so family ins and outs that lead to one or another eye color may not be as perceptible as we believe. Eye color can also change as a result of other factors such as our age, as melanin accumulates in our eyes, which usually happens during growth. Certain medical conditions, Beaver adds, can also influence this color. In Xataka | We have been trying to decipher if all humans see the colors the same.

We all know that green is to advance traffic lights. Less Japan, defending that green is actually blue

by

A long time ago We count A fascinating story that had the traffic lights and China as protagonists. It turns out that Beijing tried to change the color of these key traffic devices because use red to “stop” It was “anti -communist”. Of colors and traffic lights also goes the following story. In Japan they have no problem with red, but with green. The blue traffic light paradox. In most of the world the traffic signal that invites us to advance is unequivocally green, but in Japan that same light It’s called blue And, in some cases, it even seems bluish in the eyes of those who visit the country. This peculiarity He has baffled to generations of foreigners, but for the Japanese it is a convention as natural as saying that the sky is blue. The explanation is not found in lamp technology or in an arbitrary decision of the road authorities, but in a Cultural and linguistic background that sinks its roots in centuries of history. The linguistic origins of “year”. In ancient Japanese, they only existed Four basic words To designate colors: red, white, black and blue. The term AO served to name a much broader spectrum of shades than we associated with blue today, including what we consider green and cyan. This linguistic heritage lasted until the Heian periodwhen the Midori word to specifically refer to vegetation and the vitality of green color. However, the force of custom kept alive The use of AO In situations where, for other languages, green nuance is evident. Thus, it is not strange that a Japanese speaks of blue apples, mountains or blue vegetables, although in the eyes of anyone they are green. The conflict. When Japan introduced traffic lights in the 1930s, the progress light was described as green, following the global convention. But in 1960, with the entry into force of the Road Traffic Lawthe term AO Shingō, the “blue signal” was officially adopted. The clash with international standards was exacerbated after Vienna Convention of 1968which set the green as the reference color. Japan did not ratify that treaty, and with it the right to continue using its own denomination was reserved. In 1973, to reconcile customary and external demands, the government decided that the lights should be of a green With a bluish enough nuance As if I could continue to be called Ao. The result was a curious balance: greenish appearance traffic lights, but culturally blue. Beyond the signals. The persistence of AO It is not limited to traffic lights. Common expressions such as aoringo to designate the green apple, Aonori for the green algae that is sprinkled on dishes such as the okonomiyaki, or Aoba for the young leaves of the trees, show how blue overlaps green in the Japanese tongue. In addition, AO acquired a symbolic value associated withor new and the immature. To say that a person is AOI means that it is still inexperienced, a metaphor equivalent to that in Spanish or English we express calling someone “green.” This crossing of meanings reveals how the language not only names colors, but also organizes cultural perceptions and associations around them. Convention turned into identity. Today, although Japanese traffic lights are in green practice, they continue being called blue by millions of people who have inherited a particular way of seeing and describing the world. What for a foreigner is a rarity or confusion, for a Japanese is a tradition that does not need justification. If you want, the tongue has been imposedwork visual perceptionand the result is an example of how cultural conventions can challenge international standards and become part of national identity. Thus, Japan’s blue traffic light recalls that the way we name things influences how we understand them, and that even a traffic light can tell a story of centuries of history, language and custom.

We have been intrigued by the “blue areas” in which longevity shoots. His secret may be in Finland

by

Scientists have observed for year “Blue Areas” With a mixture of fascination, suspicion And a pressing question: are there places that people usually enjoy longer and healthier lives? Is it easier to meet centenary people in certain regions From the planet, like Okinawa (Japan), Ikara (Greece) or Sardinia? And if so, why? A group of Finnish researchers believe they have found A new candidate To “Blue Zone” to the west of your country, a finding that can help us better understand these mysterious areas. For now, they have already managed to generate expectation. What happened? Some time ago a group of researchers from the Åbo Akademia University based in Turku (Finland), a peculiar objective was proposed: finding out if a part of its country fits the characteristics of what is usually known as ‘blue areas’geographical areas that stand out for the high longevity and healthy life habits of its inhabitants, two realities that experts believe they are directly related. To be more precise Nordic scientists focused on a handful of territories of the old Western Finland: The Swedish majority region of Ostrobotnia, South Ostrobotnia and the Åland islands. As explained in The article In which they have reflected their conclusions, their idea was to analyze the longevity indicators and then find out if the best results corresponded to the cities in which people enjoy a healthier lifestyle. But … What is “blue zone”? Regions in which people (apparently) enjoy longer and more healthy lives than normal. It is not a new concept. Its origins can be traced At least until 2004when the magazine Experimental Gerontology public A broad study on the centenary population of Sardinia, Italy. In it the authors marked with that color (blue) the regions of the map in which the longevity data were higher. In addition to identifying them geographically, researchers speculated that these indicators could be explained by factors such as nutrition, lifestyle or the proliferation of genetic characteristics that favored the locals. The fact is that the ‘blue areas’ liked and shortly after, in 2005, a journalist from National Geographic He used it in Another article in which he talked about three regions of the planet where on average the population enjoyed longer and healthy lives: Okinawa, in Japan, Loma Linda, in California, and Sardinia. The text was affected in the same idea: the phenomenon connects with certain healthy habits in these territories, such as nutritional diets, physical activity, stress control and moderate alcohol consumption, among others. And what did they find out in Finland? Åbo researchers identified a series of curious phenomena who, in summary, have taken them to conclude That the Swedish region of Ostrobotnia “could be a blue zone”, with a population characterized by its high life expectancy, health and positive life habits. However, that’s just one of your conclusions. And maybe not the most interesting. To understand it it is necessary to know Your study and the figures on which it supports. What figures? The most interesting are longevity. According to The data collected in Journal of Aging Research In the åland islands life expectancy among babies who came to the world between 2020 and 2022 was 83.5 years, in ostrobotnia of 83.1 and in southern ostrobotnia of 81.8. Any of these data exceeds both the mean of Finland (81.6) and EU’swhich is around 81.5. Worldwide, life expectancy at birth in 2022 was 72.6 years and, According to statistathat global average will not approach that of Ostrobotnia until the end of the century. Of course, it is a global average. In Spain the data is already Very simulate. And what does that tell us? The Åbo team did not limit himself to studying longevity records. After all, the blue areas have not been analyzed only according to demographic data. Experts also take into account factors such as “lifestyle and health”, which includes social relationships, diet, physical activity or even vital purposes. By taking into account these parameters, experts reached a conclusion: the relationship between them (longevity and the characteristics of blue areas) are not as evident as one would expect. What does it mean? That the greatest longevity data are not necessarily in the regions that best fit the ideal characteristics of a “blue zone”. It sounds confusing, but it is better understood with an example. The longest study of the study was Åland, an area that effectively presents good health data, but is “diverted from several principles” of what could be considered the ideal lifestyle. In part of Ostrobotnia something different happens: the healthy lifestyle is well implanted and yet its life expectancy is less than in other areas. What is the conclusion? There are several. To begin the researchers concluded that, if the age, health and implementation of the lifestyle of the blue areas, the Swedish Obstrobotnia are taken into account It could be considered Perfectly one of those redoubts that stand out for their longevity. Just like Other regions of the planet, such as Okinawa, Ikara or Oglybasra. However, research throws another more interesting reading, especially in the face of future studies on blue areas: when analyzing them it is important to take into account the context. “The possible coherence between longevity, health and lifestyle I could vary in different cultural, political, social and economic contexts,” indicates the articlewhich acknowledges that their data shows that “the Nordic regions with greater longevity are not necessarily adhere to the lifestyle of blue areas.” In other words, they insist: “The important lifestyle principles for longevity can vary in different regions.” Why is it interesting? Because beyond the implications it may have for Western Finland, its authorities, doctors and demographers, research throws new data and keys to the study of blue areas, a concept that in recent years has aroused two feelings: fascination … and skepticism. Since National Geographic public Your article The concept has generated debate and suspicion of those who warn that their scientific base results Little solid. In 2019 Dr. Saul J. Newman launched An article in which … Read more

fried eggs with blue yolks

by

It all started, as things always begin on the Internet, with a user on social networks flying an unasquible flag for the rest, an unattainable top: an AI does something better and faster than the rest. Only this time bone touched: the hordes of Speedrunners of Photoshop They were willing to claim human talent, even if it were something as apparently useless as the yolk of an egg. Blue eggs: Origins. The phenomenon began on August 11, 2025, when the X @Multimodalart user promoted the image generator by Alibaba Qwen-image Highlighting that very few models could, for example, create a fried egg with blue yolk. The reason: the models of AI learn patterns of real images (that is, eggs with always yellow or orange yolk), which presents difficulties for this type of generators by not starting from a real model. First answerwhich summarizes the future of events and that we save translate: “You can do in photoshop you retard”. World records begin. The first viral response response came quickly: user @isthisa3dmodel tweeted that That could be done in Photoshop in 30 seconds. And then the demonstrations began to arrive: @c_over_d_eq_pi He did it in just five seconds and he continued to purify the technique until he reached some fulminants 0.12 seconds of time. But the competition had only begun, and like every good meme of “Doom in places“The tests in tools much simpler than Photosop began arriving. Egg avalanche. When the X user @ceee asked for participation in the challenge of users who did not strengthen experts, began to arrive Speedrunners that used much more elementary and accessible tools than Photoshop. For example, @Pantoya It achieved very competent results with an image editing tool on the mobile. AND @v2tism He did it with Clip Studio Paint, revealing the secret: it can literally be done with any tool that allows layer edition. What’s behind. The challenge of the yellow yolk is more than a kind tangan (the blood did not reach the river at any time): it is the perfect thermometer of the current vision we have on the Internet of the amazing advances of the image editing tools with AI. The clash raised, thanks to the ironic and carefree tone of the responses, that perhaps the artificial intelligences enthusiasts were overvaluing the abilities of AI: as one of the contestants said, perhaps the interesting thing is not that they can now paint a yolk in blue, but until now they could not and sold us as the panacea. What gives us lessons about their abilities of the present. A debate from the past. The absolutely spectacular capabilities of new tools, Like Google Banana Nanocapable of making very advanced editions from Prompts Very simple (and yes, we have tried it: simply with “paint the yolk of this egg” blue ” The result is impeccable) They keep the background of the debate. It is no longer about whether the AI ​​understands the blue yolk or not: it is about whether it is necessary that we replace all manual, artisanal and traditional works with automatic equivalents. It is a debate that is far from finishing. Image | Know Your Meme In Xataka | 14 tools to create free images

The return of the blue dragon after three centuries

by

In recent days, several bathers have been paralyzed in front of a strange finding: a tiny be blue, floating mouth on the foam of the sea. His silhouette seems a cross between a marine jewel and a character out of a pokeball. It shines in electric tones, displays appendages in the form of wings and moves with the lightness of an acrobat. It is the blue dragon (glaucus atlanticus), a nudibranchium that barely measures four centimeters, but has caused the closure of whole beaches. In Guardamar del Segura (Alicante), the council of beaches defined it to the information With humor as an army of “Pokemons doing pirouettes.” The comparison may sound sympathetic, but behind its lovely appearance there is a warning: this animal can chop and cause painful reactions. Minipokémon on the beach. In recent days, the people of Guardamar del Segura in Alicante has become an epicenter of the phenomenon. On beaches such as Vivers, Centro and Ortigues, the City Council has been forced to raise red flag after the detection of specimens by lifeguards. Although it has not been the only place, because very close to there, on the beach of La Mata (Torrevieja), dozens of blue dragons have also been located, which has confirmed that it was not an isolated case, as they have indicated In local media. A visitor that expands. The blue dragon is not limited to Vega Baja. According to the countryspecimens have been recorded in Mallorca, where they have not documented for more than three centuries. Also in Santa Barbara in Cádiz and on several beaches of the Campo de Gibraltar, such as Sotogrande and the line, which had to close by caution. To this list are added Canet d’e Berenguer (Valencia) and Famara (Lanzarote), where bathers and authorities also notified their presence. As experts have explained National Geographicthese animals reach the shore dragged by currents and winds of lift from the high seas, their natural habitat. Behind these dragons. The glaucus atlanticus floats mouth and wears a striking electric blue with silver tones that make it look like a fantastic creature. His deployed appendices inevitably remember characters such as Vaporaeon or even gyarados of the Pokémon saga. However, its appearance hides a sophisticated defense mechanism: when feeding on jellyfish and hydrozoos, the blue dragon accumulates its urticating cells at the ends of its appendices, becoming an animal capable of causing cutaneous reactions. According to National Geographictheir bites are not lethal, but painful: they can cause a sensation of intense burning, nausea and vomiting. Is there a real danger? The scientific community asks for calm. “Close beaches for three or four specimens is an overreaction because there is no scientific evidence of its danger,” says Juan Lucas Cervera, Professor of Biology at the University of Cádiz In statements to El País. The Municipal Biologist of Torrevieja, Juan Antonio Pujol, agrees that documented lesions are slight and that they often confuse with jellyfish bites. Opportunity for science. Beyond the tourist alarm, the appearance of the blue dragon opens a window of knowledge. The University of Valencia and the Oceanogràfic, together with the University of Alicante, have received living specimens to study their genetics, origin and behavior, as the information has detailed. In this way, researchers will be able to confirm whether these individuals come from the Atlantic and arrive at the Strait of Gibraltar or if they begin to consolidate in the Mediterranean. Pujol has remembered in chain to be That is not an invasive species: it was already described in the Balearic Islands in 1705, although its presence has been extraordinarily rare. Security recommendations. The authorities and experts insist on four basic guidelines: Do not touch it under any circumstances, even with gloves. Do not capture it or take it to lifeguards; It must remain in the sea. Notify surveillance services to register the sighting. In case of bite, go to the health center and avoid home remedies. A fascinating case. The blue dragon has generated a stir in full tourist season, thanks to its rarity and beauty. Some point to climate change as a possible cause, but experts ask for prudence: although the Mediterranean has reached record temperatures Of more than 28 degrees, there are no conclusive evidence to directly relate its proliferation to global warming. Beyond theories, science celebrates a unique opportunity to study a species as striking as unknown. With unique behaviors – found on his back to camouflage himself, he is a hermaphrodite and can put 10 to 30 eggs in his prey – the blue dragon symbolizes how much remains to be discovered in the seas that surrounds Spain.

For centuries the blue pigment recipe used by the Egyptians had been a mystery. We just solved it

by

Not all Treasures They are made up of jewels, gold and precious stones. For a long time a group of researchers from Washington State University It is behind of a treasure equally fascinating but much more elusive: the Egyptian bluethe synthetic pigment older which is recorded and that once used the artists of the ancient Egyptian to decorate from alabaster bowls to coffins, ceramics and murals. Despite their enormous popularity and that the Romans continued to use it, their recipe was lost over the centuries. Until now. What is Egyptian blue? One of those mysteries that has been intrigued by archaeologists in half the world. Egyptian blue is basically a dye that stands out for two reasons. The first, because it is the synthetic pigment older known to date. It was used thousands of years ago. The second is its bluish tone, which allowed artists to use it as a much more expensive mineral substitute, such as turquoise or lapislázuli. With everything and although we talk about “Egyptian blue” in general, the pigment was very heterogeneous. Depending on where it would have been manufactured, how it would have worked with the material or quality of its components, the tone could vary between gray, a more or less deep blue and a green off. A factor that influenced the process for example was how quickly cooled the mixture. How old is it? Quite. We know that Egyptian blue was already used 5,000 years ago. And that at least. In fact The oldest sample Known is a small alabaster bowl made in the 3250 AC The pigment was used in ceramics, sculptures, murals, sarcophagi, pieces that we still keep today and show its bluish hue. It was also applied to different surfaces, such as wood, stone or cardboard, a material similar to Paper Maché. Did you only use the Egyptians? No. His color liked the artisans so much that the Romans ended up incorporating it into their palette after the conquest of the ancient Egyptian and came to be used during the Renaissance. The Smithsoninan Institute remember that a few years ago it was discovered that at the beginning of the 16th century Rafael used Egyptian blue in the fresco ‘Galatea triumph’a work elaborated for the Villa Farnesina, located in the neighborhood of Constévere, Rome. Although Rafael’s intention could be to imitate the old Roman technique, the Washington State University (WSU) Precise that during the Renaissance the pigment formula had practically fallen into oblivion. That is what a team of researchers has now wanted to solve led by the American institution and who has worked side by side with the Carnegie Museum of natural history and the Institute of Conservation of the Smithsoninan Museum. And how have they done it? Based on trial and error. And try again and again until you give in the nail. The team He thoroughly examined Pigment samples and elaborated 12 recipes in which he experienced with different raw materials and elaboration times. The results have been reflected in An article Posted in NPJ Heritage Science in which he details how he worked with mixtures of silicon, copper, calcium and sodium carbonate dioxide. The main ingredient is the cuprov. To complete the process, the mixed mixture warmed 1,000º Celsius For different times, between one and 11 hours, in an attempt to replicate the temperature with which the ovens of the time work. The resulting samples were also cooled at different speeds to then study their pigments through microscopy and analysis techniques. The results were compared to real pieces of ancient Egypt. Is it so complicated? Beyond the materials used or the techniques with which they were mixed, the great challenge for archaeologists has been to replicate the exact tones that Egyptian artisans worked. “One of the things we observed was that with small variations in the process very different results were obtained,” John McColy commentsone of the authors of the study and director of the School of Mechanical and Materials Engineering of the WSU. “There were people who made the pigment, he transported it and then used it elsewhere.” During their study the researchers in fact discovered that to obtain the most bluish hue, only half of the components that generate the blue color were needed. “It doesn’t matter what the rest contains and that surprised us”, Add McCloy. “You can see that each particle contains a lot of elements. It is not uniform, much less.” To such an extent that the WSU acknowledges that one of the conclusions reached by the experts is that the pigment is surprisingly diverse. Did you achieve your goal? That seems. In A statement Run a few days ago the WSU says that after trying different formulas and examining the results in detail, its team has managed to “recreate” the famous Egyptian blue. The feat is not only the result of curiosity or advance to better understand the art of the ancient Egyptian. WSU herself recalls that in part the renewed interest in the Egyptian pigment responds to more pragmatic reasons. “In recent years, interest in this pigment has resurfaced due to its optical, magnetic and biological properties, with potential new technological applications,” Point out The institution. “The pigment emits light in the nearby infrared of the electromagnetic spectrum, invisible to the human being, which means that it could be used for purposes such as traces and create anti falsifications.” Images | Washington State University, Matt Unger, Joshua Franzos and Carnegie Museum of Natural History In Xataka | A 2,000 -year -old cup has revealed an unexpected facet of the Egyptians: psychedelic cocktails

It is a direct bullet to the blue links that restless and excites equal parts

by

This year’s google has left us with very interesting pearlsespecially as far as artificial intelligence is concerned. It is clear that Gemini It has been the most important tourist attraction of this year and makes all the meaning of the world. It has been so that the company has completely set aside Android In your most important event. Although of course, for this we already had A separate event With all the news. In addition to all the tests with Project Moohan and the Google glasses with GeminiI have also had the opportunity to try Ai modethe new and revolutionary function with which Google intends to completely transform your search engine. We are no longer facing simple results with some of the above; This is a radical change in the way of looking for information, and it was all that we expected from Google from the AI ​​boom. Finally, the company has decided to take the step and under these lines I tell you what it seemed so far. Google Search makes the leap and transforms completely into a search engine with AI To access AI Mode I had to change my region to the United States through Search Labs, since it is not yet available in Europe. Once the change is made, on the main page of Google, where the “I will be lucky” (may rest), now “ai mode” is now. It will also arrive for mobiles, but I still couldn’t try this aspect. Here instead of typing keywords and get a list of links, now You convers with the search engine as if you’s talking to a person. Image: Xataka During my first searches I tried to determine if Gemini would guess the name of a place I went without me saying anything, but describing what was in the menu. “I don’t remember the name of a restaurant I went in Jaén, but I know there were tacos in the letter. Could you tell me what it was?” I asked him in English (the only language available for now). What I got was not a simple list of establishments, but a complete, contextualized response and with all the relevant information On several restaurants that fit my request. I also tried “I am looking for an economic gym for Madrid that does not exceed 35 euros.” The answer was instantaneous and, most importantly, exactly what I needed: concrete options with details about prices, schedules and valuations, all perfectly organized. Main tab of AI Mode in Search | Image: Xataka Here, logically there is still room for hallucination, so we must be attentive and make a double check. However, for practically all my searches, I found what I was looking for an instantaneous waydetailed and precise. Ai mode is not simply gemini integrated into the search engine. As explained to me on Google, the system uses a technique called “Query Fan-Out”, which Divide your consultation into multiple sub -themes and performs hundreds of simultaneous searches. It is as if you had a researcher working for you at full speed. Image: Xataka This approach allows the search engine deepen the web much more than a traditional searchdiscovering hyperrelevant content for your specific question. The function uses a personalized version of Gemini 2.5which is now integrated into both AI Mode and AI Overviews in the United States. Not only seeks: it also goes to action Image: Xataka The most impressive thing about AI Mode is that it is not limited to informing you, but that It can help you complete tasks from beginning to end. The example of the entries of the reds explained by Google In his blog It is good, because the search engine guides you step by step from options to buy them, including the possibility of filling forms and making payment through Google Pay. This function will be initially available for events, reservations in local restaurants and appointments, with the collaboration of platforms such as ticketmaster, Stubhub or Resy. The control, yes, is still in the user’s hands at all times. Although of course, we still have no details about his arrival in Spain. Search Live: Google Lens’s definitive evolution I also had the opportunity to try Search Live, one of the most surprising novelties. This function allows to interact in real time with the search engine Using the mobile camera, turning Google into a true visual partner. I described it as having a “todologist” at any time to help us in any task. During the demo, I simply pointed to the camera to a shelf full of board games and books, and I could ask directly about what I was seeing. The system identified the objects and offered me detailed information about each one, answering my questions in real time as if I had an expert by my side. Search Live is what Google Lens should have been for years. With the integration of AI, it now makes much more sense and its use is tremendously intuitive. It’s like having a personal assistant who sees what you see And you solve any questions instantly. Deep Search: a group of scientists at your disposal Another promising function that will soon arrive at AI Mode is Deep Search. Is designed for when you need an exhaustive investigation on a topic. It really is something similar to the models of the “deep research”, with the ability to reflect, but available in Search, which combines the search concept in a product with more packaging. As they could explain, Deep Search carries Query Fan-Out technique to the next level, doing hundreds of searches, crossing information from different sources and preparing a full report with references in minutes. It’s like having a team of researchers working for you. The searches will change from here to very little, and there is nothing to stop this train Ai Mode is all we expected from Google when he took a certain traction with the generative AI, something that, so we have seen in the Google … Read more

Blue Origin now has a golden opportunity to advance Spacex on trips to the moon. And he is taking advantage of it

by

The Lunar exploration panorama has changed with the new US administration. Blue Origin, the Jeff Bezos space company, is strategically positioning to capitalize on the recent turbulence of the NASA Artemis program. Short. With Boeing and Lockheed Martin outside the future lunar missions after the Cancellation of the SLS Rocket and the Orion shiptwo companies are the clear favorite to reconfigure the NASA Artemis program. Although Spacex has led the commercial narrative so far, its focus centered on Mars and the Technological developments of competition They could offer Blue originated a window to, if not advance, at least equate forces in the race towards our natural satellite. First flight this year. John Couluris, the leader of Blue Origin’s lunar efforts, has revealed New details about architecture and The road map From the company’s missions to the moon. In a presentation of the Lunar Surface Innovation Initiative Conference, Couluris said Blue Origin planned to do A demonstration flight without crew from its lunar module Blue Moon Mark I to the South Pole of the Moon before the end of the year. Blue Moon Mark I. Blue Origin’s first lunar module was designed to launch aboard the new Glenn rocket. Driven by a single be-7 engine of liquid oxygen and liquid hydrogen, can transport up to 3.9 tons of load anywhere in the lunar surface with a precision in the alun of less than 100 meters, according to Blue Origin. The Mark I will not only serve as a test bench for technologies of the future Blue Moon Mark II ship, Yes with the ability to carry astronautsbut it will transport commercial and NASA useful charges to the Moon, including an experiment to measure the impact of the BE-7 engine on the lunar surface. Blue Moon Mark II. Blue’s true bet for dominating trips to the Moon is its Blue Moon Mark II, capable of taking four astronauts or between 20 and 30 tons of load to the Moon, depending on whether it is the reusable or disposable version. Here the newly announced Cislunar Transporter comes into play, a key piece that improves Blue Origin’s strategy with that of Spacex and its gigantic Starship ship. This vehicle, also driven by BE-7 engines, is designed to transport up to 100 tons of load from the low terrestrial orbit to a lunar orbit. Cislunar Transporter. Blue Origin’s lunar architecture begins with a New Glenn rocket by placing the transport in the low terrestrial orbit. Additional rocket launches would take advantage of the upper stage of the New Glenn to fill the liquid hydrogen and oxygen tug tanks. Once full, the Transporter southern would travel to an almost rectilinear halo (NRHO) next to the moon. The Blue Moon Mark II lunar module, thrown into another New Glenn, would go to that same orbit, where it would be attached to the transport to recharge its tanks, obtaining the necessary fuel to alunize and return to the NRHO. Simpler than Starship. Blue Origin’s architecture is easier than the HLS system of Spacex, in which a starship stays in terrestrial orbit and has to be coupled with several starship-cysterna (a maximum of eight, a maximum of eight, a maximum of eight, According to Elon Musk) Before recovering enough fuel to travel to the moon. On the other hand, Blue Origin is moving forward in the storage technology of cryogenic propellants without evaporation (“Zero Boil-Off”) that he hopes to demonstrate in June 2025 to solve one of the main problems of liquid fuels in long-term missions. An opportunity. These Blue Origin advances charge special relevance to the drastic cuts proposed for NASA. The 2026 budgets propose the cancellation of the SLS rocket and the Orion ship after the Artemis III mission, scheduled for 2027, which will use a Spacex starship to transport astronauts from the lunar orbit to the satellite surface. This dismantling of the Artemisa program As we know it leaves a vacuum that the White House intends to fill with rockets and commercial ships that allow more ambitious subsequent lunar missions. Although Spacex with Starship is an obvious candidate, Blue Origin is making it difficult.

A huge blue spiral appeared in the sky of Europe at 9 at night. It was the wake of a spacex rocket

by

It is hard to believe, but the last night were not aliens either. If you were looking at the sky at 20:55, European central time, you could see a bright blue spiral illuminating the night. It was a Spacex rocket. A strange show. In United Kingdom, Belgium, Poland either Ukraine. From The clean skies of Sierra Nevadain Granada. Virtually all of Europe has managed to capture the spiral light that crossed the sky last night. They soon appeared photos on social networks. People asked what that strange phenomenon was. It is not a usual show, although it has already been seen in Hawaii, Alaska either Iceland. A Falcon 9 of Spacex. Neither a missile, nor a satellite, nor a galaxy about to swallow us. Nor a UFO. The object had a name and surname because it was a Falcon 9 rocket of Spacex by recentrating in the earth’s atmosphere. He had taken off from Cabo Cañaveral, east of the United States, two hours before. The Spy Nrol-69 satellite of the American National Recognition Office (NRO) had put in orbit. And he was returning to the earth to disintegrate in the atmosphere in a controlled way. What caused the spiral. Before a controlled reentry, the 13.8 -meter length rocket rotates to get rid of the fuel that is still in its deposits; A process called passivity. The low temperatures instantly froze the propellants released by the rocket, which added to the turn movement and the position of the sun caused the light show over Europe. The turn is what made it look like a spiral, and the sunlight was what illuminated the frozen wake. Nothing to do with the incident of Poland. In February, the second stage of a Falcon 9 rented without control over Europe. Several pieces of the rocket fell into populated areas of Poland, without causing damage (except the dismissal of the president of the Polish Space Agencyfor its management of the incident). In this case, and as is usually the case, the second stage of Falcon 9 successfully turned on its engine to fall controlled in the atmosphere, far from populated areas. They were the light conditions and the flight profile that made its wake visible in the European night sky, without further consequences than the scare of some European spectators.
