Blue Origin equals SpaceX in rocket reuse but fails in the mission

Blue Origin has reused the propellant of its New Glenn rocket for the first time, reaching a milestone that until now had only been achieved by SpaceX. With this achievement, it is one step closer to its main competitor, which is also beginning to hinder its path to the Moon. However, this launch has been accompanied by some errors that still allow Elon Musk’s company to breathe easy. The good and the bad. Last November, Blue Origin managed to recover the propellant for the first time with which he had launched a New Glenn rocket into space. Their goal was to reuse it, exactly as SpaceX already does routinely. That second achievement has been a long time coming, but it finally took place this Sunday, April 19. The launch was carried out successfully, but there was a problem: The satellite it was carrying as a payload was placed in the wrong orbit. Therefore, although this is a giant step for Jeff Bezos’ space company, there are still details to be refined. Background. Blue Origin had already managed to reuse the propellant of a rocket, but it was not a New Glenn rocket, but a New Shepard. This one is smaller, so it was less of a challenge. To match SpaceX, it needed to do the same with a larger rocket. For this reason, the company’s goal has long been set on reusing the first phase of a New Glenn. This one measures 98 meters high. The New Shepard only 18 meters. A failed attempt in January 2025. To reuse a propellant, it must first be recovered. This occurs after the rocket launches. The two phases separate and, while the second continues the journey to leave its payload in place, the first returns to Earth. Ideally, a vertical landing or splashdown should occur, so that the propellant can be recovered intact. Blue Origin already tried this with a New Glenn rocket in January 2025, but a failure to fire the engines during descent prevented it from being done correctly. In November, however, complete recovery was achieved. That has been the propellant that has now been reused. SpaceX has reused its Falcon 9 hundreds of times Other companys. In reality, the only space companies that have achieved reuse of this type have been Blue Origin and SpaceX, although there is another that has done something similar: Rocket Lab. In their case, a vertical landing of the first phase does not occur, but instead It lands in the ocean with the help of a parachute. It is also useful, but recovery is more complicated. Furthermore, this company has not yet achieved complete reuse of the recovered rockets. Other companies, like the Chinese LandSpacethey also intend to follow in the footsteps of SpaceX, but are still carrying out tests. Importance for the future. Rocket reuse is important for many reasons. To begin with, what companies look at most: their economy. Not having to manufacture a new propellant with each launch greatly reduces costs and allows investment in other technologies. On the other hand, it is useful and necessary for reduce space debris levels. SpaceX does not stop generating new space junk by sending satellites into space. Few experts consider that the reuse of rockets will compensate for that, but it continues with its particular space greenwashing. SpaceX has made a lot of progress in this regard. Their reuse of rockets has already become routine, with more than 500 reused takeoffs from its Falcon 9. It has also been possible to reuse the powerful Starship. Even Rockets have been recovered in flight with a kind of giant Chinese chopsticks. Now, Blue Origin is closer, but if they want to continue in the competition they must be more accurate. An investigation is underway as to why the satellite did not end up in the correct orbit. When you find the answer, you can look for solutions.

35% of its chip manufacturing machines are already of Chinese origin

Foreign lithography and wafer processing equipment manufacturers are selling less and less in China. In 2024, the country led by Xi Jinping represented 41% of ASML revenuebut in 2025 this figure dropped to 33%. And presumably in 2026 will contract up to 20%. Something very similar has happened to the American wafer processing machine manufacturer Applied Materials: its sales in China have gone from 37% of its total sales in 2024 to 30% in 2025. In addition, sales in China of the American companies Lam Research and KLA, and the Japanese Tokyo Electron, also have decreased during 2025 compared to those they obtained in 2024. This obvious trend is the consequence of two factors. On the one hand, US sanctions prevent US and allied manufacturers of lithography and wafer processing equipment from delivering their most sophisticated machines to their Chinese clients. The Dutch company ASML is most likely the most affected in this scenario. On the other hand, in response to pressure from the US, the Chinese Government is supporting the adoption of machines of Chinese origin in its integrated circuit factories. In fact, in 2025 the national tools represented 35% of the equipment in use in semiconductor plants, and Xi Jinping’s Government aims to reach 50% in new factories during 2026. Its purpose is clear: China’s chip industry needs to achieve technological independence as soon as possible in its fight with the United States. China has made great progress, but lithography remains its weakest point The resources that the Chinese Government is allocating to its designers and manufacturers of wafer processing equipment are bearing fruit. And they already compete face to face with foreign companies in the field of deposition, thermal processing, etching and cleaning of wafers. However, there are still no extreme ultraviolet (EUV) photolithography machines of Chinese origin in Chinese IC factories. Presumably they will arrive before this decade endsbut this is for the moment China’s real Achilles heel. One of the Chinese companies worth keeping track of is Pulin Technology. This organization has opted, like Naura Technology, AMEC (Advanced Micro-Fabrication Equipment Inc. China) or Piotech Inc., to develop your own cutting-edge photolithography machines. And the achievements are coming little by little. In mid-2025 Pulin sent one of his clients your first cutting-edge equipment using nanoimprint lithography technology (known as NIL for its English name NanoImprint Lithography). In mid-2025, Pulin sent one of its clients its first cutting-edge equipment NIL technology is not new. The Japanese company Canon has its own commercial NIL solution for yearsand presumably its operating principles are essentially the same as those of the machine designed by Pulin. On paper, NIL photolithography equipment is an alternative to printing machines. extreme ultraviolet lithography (UVE) designed and manufactured by the Dutch company ASML, although no to the high aperture version of these teams. The latter are currently the most sophisticated and expensive that exist. Very broadly speaking, the production of silicon wafers in the latter requires very precisely transporting the geometric pattern described by the mask to the surface of the silicon wafer using ultraviolet light and extremely refined optical elements. NIL lithography, however, allows the pattern to be transferred to the wafer without the need for intervention in the process. an extremely complex optical system. This strategy is simpler and cheaper, but it also involves the execution of several sequential processes that make it slower than UVE and UVP lithography. Canon assures that its nanoimprint lithography equipment can be used to manufacture integrated circuits comparable to the 5nm chips that TSMC, Samsung or Intel produce with ASML’s UVE machines. And in the future, with the refinements that will arrive, they will be able to manufacture 2nm chips. In addition, a NIL equipment costs ten times less than an ASML EUV machine: 15 million dollars compared to the 150 million dollars that the Dutch company asks its clients for an EUV machine with numerical aperture 0.33. We still don’t know how much each Pulin NIL machine costs, but it is reasonable to predict that at most it will have a cost comparable to that of the Canon machine.

A Moroccan sued a real estate agency for not showing him an apartment just because of his origin. Now they will have to pay 10,000 euros

The story sounded so strange, so much like an ‘improvised excuse’, that Hamid Hmata decided to do an experiment. In January 2024after seeing how the umpteenth real estate company closed the door on him after finding out about his Moroccan origin, Hamid asked a co-worker to help him out. His friend (with a Spanish name) called the same agency asking about an apartment in Mataró that Hamid had been interested in shortly before. He had no problem. They confirmed that the home was available, gave him information and scheduled an appointment. Shortly before, Hamid had been told the opposite, that it was already rented. The story could have stopped there, but what the agency probably did not take into account is that Hamid has been battling discrimination in access to housing for some time. Now that episode of 2024 has led to a pioneering sentence by “real estate racism”. a dozen complaints. The statistics They suggest that Hamid is not (far from it) the only immigrant who encounters obstacles or outright racism when looking for housing. His case is different in something: this man of Moroccan origin, father of two minor children and with the necessary income to pay for a rental house, has been denouncing real estate racism for some time. And he has also done so in an active way, calling out against various agencies and presenting a dozen complaints before the Mataró City Council. “For being a migrant”. His case was revealed ago just a month and a half the DESCA Observatory, one of the entities that has accompanied Hamid in his peculiar real estate crusade. At that time, the platform explained that the man had been looking for an apartment for four years, a long period during which he had dealt with “great difficulties.” The reason? Everything indicates that its origin. “Different real estate agencies, allegedly, would have covertly avoided providing him with their services (showing him the apartment, evaluating his candidacy, managing a contract, etc.) due to the fact that he was a migrant,” details DOWNLOAD From office to office. Despite his efforts, most of Hamid’s claims were unsuccessful. Their complaints to the City Council ended up being filed and they undertook a “bureaucratic journey” by different organizations, such as the Housing Agency of Catalonia, the Consumer Agency and finally the Office of Equal Treatment and Non-Discrimination. Almost all of Hamid’s complaints ended up being dismissed, but last month DESCA recalled that there were still three live files: two “in the administrative procedure phase” and another “in the preliminary proceedings phase.” And the big surprise came. We have now known the next chapter in Hamid’s real estate odyssey. a few days ago DESCA revealed that the Office of Equal Treatment and Non-Discrimination (OITND) of the Generalitat of Catalonia has imposed a fine of 10,001 euros on a real estate agency in Mataró for, the association claims, “a case of real estate racism in access to rentals.” The reason would have been the episode with which we started this article. Same floor, different answers. In 2024 Hamid was interested in an apartment for rent, so he contacted the real estate agency that owned it to visit it in person. He couldn’t. A day and a half after requesting the interview they told him that it was already leased. The explanation did not convince Hamid, who asked a colleague (in this case with a Spanish name) to call the agency to inquire about the home in question. Same agency, same apartment… different answer. Him, ensures DESCAYes, they made an appointment for him. Click on the image to go to the tweet. “True, but it has nothing to do with it.” Determined not to let the matter go, Hamid attended the visit scheduled by his friend to ask the head of the agency for explanations. Specifically, I wanted to know if the problem was that the owners of the apartment did not want to rent it to a person of Moroccan origin. “The administration admitted it: ‘That, that’s also true, but it has nothing to do with that. It’s reserved,’” reveals DESCA. The phrase is reminiscent of the one he received recently as well. another moroccanin this case from Irún, who was looking for a home. Mosqueado recorded the explanations of the head of an agency that had slammed the door: “The owner doesn’t want anyone from outside.” A figure: 10,001 euros. Hamid’s experience demonstrates several things. To begin with, proving an episode of “real estate racism” is not easy (he has denounced a dozen agencies). The second is that when it is detected it is expensive. DESCA explains that, in this case, the OITND has fined the agency a fine of 10,001 euros, although that is only part of the punishment. For one year you will not be able to receive any public aid or subsidies, nor establish contracts with the Generalitat Administration. “The OITND resolution recognizes that the reported facts consist of a case of discrimination in access to housing for ethnic-racial reasons and/or origin, which according to Law 19/200 on equality and non-discriminatory treatment is a serious infraction,” argues the observatory. The standard to which the platform refers clearly states in its section 14.3 that real estate agencies and their clients “must respect” equality and not discriminate. Why is it important? For several reasons. The first, the pioneering nature of the sanction. At least in Catalonia, where according to the RAC1 chain There is only one similar precedent. In 2022, Barcelona City Council revealed that the court had ratified a fine of 90,001 euros which he had recently imposed on “a real estate agent” for “excluding a group of people from access to housing due to their origin.” On that occasion the trigger was an advertisement for an apartment that only accepted Spanish tenants. The fine that the OITND has just imposed is interesting for another reason. There are studies that suggest that real estate racism is far from being a one-time phenomenon. In … Read more

We have been searching for the origin of life in hot puddles for years. Bennu has shown that radioactive ice works just as well

When the capsule OSIRIS-REx mission landed in the Utah desert in September 2023, NASA knew it had a treasure on its hands. We are talking about a bit of black dust that was collected millions of kilometers from Earth and that was about to rewrite one of the most important chapters of science: the origin of life. What we knew. Until now, the predominant theory regarding the origin of life told us that for “cook” all the basic components of life, such as amino acids, heat and liquid water were needed to make a kind of hot chemical soup. However, science has just flipped the script: the bricks of life They are not only formed in heatbut they can be born in the most extreme cold and under gamma radiation. And that completely changes our understanding of how we got here, and also of the possible presence of life in any corner of the Universe. The importance of Bennu. Definitely is the protagonist of this whole story, and it is nothing more than an asteroid of about 500 meters in diameter which functions as a fossil from the early solar system. But the most interesting thing is that it is approximately 4.6 billion years old, the same age as the Earth, although, unlike our planet, its surface has not melted or been drastically altered by geological processes throughout its ‘life’. And little by little we are learning more about this asteroid thanks to the samples brought by OSIRIS-REx that had already been confirmed in preliminary analyzes an unusual abundance of carbon, nitrogen, water and organic compounds. But what the team led by Penn State University has now found goes one step further. The surprise. This same team, when analyzing the isotopic composition of the amino acids present, especially glycine, came across a chemical signature that did not fit with the classical theory of formation in hot water. A radioactive freezer. Until now, we thought that amino acids in asteroids were formed primarily through aqueous alteration processes: ice melts from heat, liquid water interacts with rock, and voilacomplex organic chemistry. However, science now suggests that liquid water is not necessary for amino acids, an essential molecule of life, to form. Simply from simple ice they can arise without much problem. And there are many of these in the universe. The catalyst. The other important factor in this formation was the energywhich in this case came from gamma radiation emitted by radioactive elements that were abundant in the early solar system. And the energy could not come from thermal heat, since this process occurs in icy environments, long before the asteroid was compacted or heated enough to have liquid water. This explains why we found amino acids both in asteroids that underwent a lot of water heating and in those that remained “drier” and colder. Life, it seems, is more stubborn than we thought and can begin to develop in the most hostile conditions of the vacuum of space. An increasingly complex menu. But we are not just talking about simple molecules, since analyzes of Bennu samples have identified a variety of compounds. Among these is tryptophan, which is an essential amino acid, much more structurally complex, and vital for terrestrial life. Besides, DNA and RNA components have been detectedin addition to ammonia and amines, surpassing in richness many samples of famous meteorites such as that of Murchison. Backlash to Panspermia. If amino acids can easily form in irradiated ice grains in the solar nebula—before the planets even formed—it means that these “ingredients” are spread throughout the solar system. The fact that Bennu, a B-type carbonaceous asteroid, is packed with these compounds reinforces the idea that Earth didn’t have to produce all the components of life itself. A constant shower of asteroids and meteorites during the late intense bombardment could having “sown” our planet with a pre-made deep space biological starter kit. That is why in the end looking at a grain of Bennu dust is looking at ourselves. Or, at least, to the chemical great-great-grandparents who made us here today.

The origin of December 25 is in an obscure third century antipope obsessed with the birth of Christ

For years, we have repeated that Christmas is an invention. Not only does the Bible not specify that Jesus was born on December 25, it is that It is implausible that it was on that date. The gospels themselves detail that there were shepherds tending flocks outdoors (something unlikely in the Decembers of the time in Bethlehem), but the idea that the Romans were going to take a census on those dates is almost delirious. For this reason, we have repeated over and over again, the most reasonable explanation is that during the 4th century, the Church set the birth of Christ on December 25 to make it coincide (and in the process ‘Christianize’) the pagan festivities of Sol Invictus and Saturnalia. The only problem is that the latest available evidence goes in another direction: that of an obscure third century antipope who, obsessed with making a chronology of the scriptures, arrived at the date of the 25th independently. This is the story of how Hippolytus of Rome invented Christmas. The myth of the Christianization of Roman festivals Hail, Caesar! Io, Saturnalia! by Lawrence Alma-Tadema But let’s start by reviewing the best-known theory and seeing why some authors They have started to doubt them. As is often read on the Internet, this theory tells us that there is nothing coincidental about the December 25 election. On that date there was already a birthday, that of the “Unconquered Sun” (which would be the winter solstice for the Romans) and the Church, which during the 4th century struggled to — and would succeed — to become the official religion of the Empire, would have taken advantage of the pull of the pagan festival to place Christmas there. And the theory makes sense. However, it has a big problem; does not really resolve the question at hand: why 25? As explained Thomas C. Schmidta researcher at Princeton University, indeed the Roman Saturnalia fell on those dates, but not on that date. Certainly, it is difficult to be conclusive when we talk about that historical period, but everything seems to indicate that the strong day of Saturnalia fell closer to the 17th than to the 25th. In fact, if this approximation is true, we could not even say that it is the end of the ‘sigilarias’ (the celebrations – of a week – that followed the birth of the Unconquered Sun). Other festivities such as the Kalends (which were already celebrated in January) or the brumals (the solstice festival) do not fit well with the date in question either. That is to say, the idea that these Roman festivals are the origin of Christmas is, as I say, suggestive; but it still does not provide a convincing explanation as to why the Church chose the 25th. To answer that question we have to dig a little deeper. Since when is Christmas celebrated in “Christmas”? As says Schmidt.the first historical reference to December 25 as the day of the “birth of Christ in Bethlehem of Judea” can be found within the Filócalo Calendarin a document dated 336. It is a curious fact. And, although it is not something that explains the central issue of our question (the reason for December 25), it does give us a time frame: it tells us where to look for that explanation because, for practical purposes, we can assume that during the 4th century the festival was already relatively consolidated. That is, you would have to search a little before. Specifically to 222. In that year it is dated a statue of Hippolytus from Rome found in 1551 near the Via Tiburtina. The interesting thing about the statue is that, among its many inscriptions, it includes a lunar tablet that is kept today in the Vatican Library. Who is Hippolytus of Rome and what does he have to do with all this? Adoration of the Shepherds, by Gerard van Honthorst Hippolytus of Rome is a very multifaceted figure. Considered one of the great theologians and preachers of his time (in fact, Origen can be considered his disciple in some respects), he led a schism in 217 that led him to distance himself from the Church for a decade. He is, at the same time, the first antipope in history and a saint who, according to what is said, died martyred 235: he is, in fact, the only antipope canonized to this day. Well, we know that already in 220 after Christ, Hippolytus (in a commentary on the book of Daniel) defended that “The first coming of our Lord, in Bethlehem, was on Wednesday, December 25.” However, we also know that this text is manipulated. There are several versions with modified dates: among them, some that explain that the birth was in March or April. And the truth is that if Jesus was born in April many of our problems would be solved suddenly. However, looking only at the texts, it is not clear. That’s where the statue comes in. Because in the lunar table of the inscriptions, all past and future Easters appear calculated and, along with them, two key notes for us: the original Good Friday (which fell on March 25) and the “genesis” of the Lord (the year 2 AD) which fell on April 2. In the year 235, in a very ambitious work in which he traced the complete chronology of creation, Hippolytus It advanced that origin to March 25 for the simple (and, seen from today, absurd) reason that that was the date on which, according to their data, the world had been created. The true “genesis” of Christmas Paolo de Matteis But what does all this have to do with December 25? The answer is in the statue although I have overlooked it: specifically, in the word “genesis.” Because what is the “genesis” of a person? His birth or his conception? While it would be better for us if it were his birth (because it would fit with what the Bible says about Christmas), … Read more

Jeff Bezos fired the CEO of Blue Origin two years ago. In retrospect, it was the best decision he could have made.

The most surprising fact about Blue Origin is that it was founded before SpaceX. Obsessed with space since childhood, Jeff Bezos saw the potential the aerospace industry would have and began selling thousands of Amazon shares to build a rocket company. He founded Blue Origin in 2000, when his net worth was around $6.1 billion. Two years later, a young Elon Musk obsessed with the conquest of Mars invested $100 million (more than half of what he had from the sale of PayPal) in founding SpaceX. Who would suspect that the company that would end up revolutionizing the sector would be that of the eccentric South African businessman and not that of the CEO of Amazon, who multiplied his assets by 30. The sleeping giant The Blue Origin coat of arms For almost two decades, Blue Origin was the butt of jokes in the sector: a company financed with infinite funds that sold 15-minute suborbital trips to millionaires, but when it came time to reach orbit it only produced powerpoints and legal lawsuits to stop its opponents. Blue Origin was aware of its apparent slowness in the face of SpaceX, to the point of deliberately adopting it as its motto. The company’s coat of arms includes two turtles and a Latin phrase that Jeff Bezos has publicly defended with pride: Gradatim Ferociter“step by step, fiercely.” But although projects such as the powerful BE-4 engines and the reusable New Glenn rocket had been in development for years, the reality is that Blue Origin did not step on the accelerator until the end of 2023, when Bezos said enough and caused a CEO change that has been like night and day. The Dave Limp Effect The first stage of the New Glenn rocket returning to the factory A little context. By 2023, under the leadership of Bob Smith, Blue Origin had become a bottleneck for US national security. The new Vulcan rocket from ULA (the company that had a monopoly on government launches until the arrival of SpaceX) depended on Blue Origin’s BE-4 engines, which kept falling behind schedule. At the end of that year, Jeff Bezos made the decision to remove Bob Smith and entrust the company to the executive who had led Amazon’s devices division during the creation of Alexa or Kindle: Dave Limp. Today, the engine crisis is more than resolved. Blue Origin has celebrated the delivery of the 30th engine to ULA, which will allow its partner to meet its launch obligations for the Space Force. But it has not been the only thing that Dave Limp has managed to channel as the company’s new CEO. Under old management, Blue Origin operated with a crippling risk aversion. He sought perfection on the first try, which translated into eternal development cycles. Limp arrived with the Amazon system under its arm: Blue Origin went from being an R&D company to becoming a real rocket factory willing to take risks. The internal culture had already begun to improve when, in February 2025, Limp laid off 10% of the workforce. “We grew too fast and lost focus,” he explained. But the effect was immediate: Blue Origin has become a company that is agile in decision-making. Instead of having a single rocket that’s scary to break, they’re a real rocket factory. So when the New Glenn finally took off, crashing on the landing attempt, it was not a single prototype: there were other stages of the rocket already on the production line. From New Glenn to Super New Glenn New Glenn vs Saturn V vs New Glenn 9×4 If anyone had doubts about Limp’s management, the events of this last year have dispelled them. Blue Origin has successfully completed two orbital launches that have completely changed the narrative, and which have soon been overshadowed by the company’s roadmap. He maiden flight of the New Glenn It was a partial success. The rocket reached orbit (and there are few rockets that can say that on the first try), but the first stage disintegrated while trying to land. Far from stopping to investigate the failure for a year, Blue Origin analyzed the data, adjusted the software and moved forward with the second attempt, as SpaceX would have done. In November, the second New Glenn successfully launched NASA’s ESCAPADE mission, two probes that were placed at the L2 Lagrange point awaiting gravitational assistance to travel toward Mars. But even a Martian mission can take a backseat when, against all odds, the first stage of the rocket landed on the Jacklyn maritime platform in the Atlantic Ocean. Blue Origin is only the second company to achieve the propulsive landing of a rocket. For the first time, SpaceX has a real competitor capable of recovering orbital-class boosters. One that uses methane for cleaner and cheaper combustion, and that promises to carry up to 45 tons to low Earth orbit. Shortly after the launch, taking advantage of the momentum of success, Blue Origin announced an improved version of the BE-4 engine and a new variant of the rocket: the New Glenn 9×4, which instead of seven engines in the first stage and two in the second, carries nine and four. In addition to a larger 8.7 meter diameter canopy, to launch larger space stations, telescopes and satellites. What does this mean? That Blue Origin is going for the “Super Heavy” category, in which SpaceX competes with the Falcon Heavy and the gigantic Starship, still in development. This variant of the New Glenn will be able to carry 70 tons to low orbit, which with Starship’s permission surpasses almost everything else on the market and, most importantly, with an architecture that has already flown and landed. To conquer the orbit and the Moon With the New Glenn 9×4 scheduled for 2027, Jeff Bezos and Dave Limp’s attention is now focused on scaling the rocket’s manufacturing and reusability capacity to reach 24 launches per year between now and then. SpaceX continues to play in its own league with 160 launches … Read more

We already have the missing ingredient to explain the origin of life

What the mission OSIRIS-REx brought back to Earth in his capsule after being perched on the asteroid Bennu It could be very enriching, but the truth is that it has exceeded all our expectations. And in the past we have already been surprised to find water or carbon in space, but now NASA has confirmed than what has been seen on this asteroid: Bennu contains sugars essential for life as we know it. But not only that, among the grains of dust and rock, researchers have come across something they did not expect: a mysterious substance that they have already dubbed ‘space gum’. The discovery. After a long time analyzing the materials extracted by this probe, the results have finally been released to a published study in Nature Geoscience led by Yoshihiro Furukawa from Tohoku University (Japan) and which undoubtedly marks a milestone in astrobiology. From a sample of just 603 milligrams of Bennu dust, the team was able to detect a variety of sugars that are biologically significant, such as glucose. This marks something historic since it is the first time that this sugar that we know so well has been identified in a pristine extraterrestrial sample. But this has not only been the important thing, but also samples of ribose which is an essential component of RNA, which is responsible for transporting genetic information in human organisms and which undoubtedly It became popular during the COVID pandemic. Its importance. Until now we had seen signs of these samples in meteorites, but there was always the shadow of land pollution upon impact. Now this doubt disappears since the samples arrived sealed. What is undoubtedly important is that the joint presence of these sugars suggests that they were synthesized by abiotic processes (without life) inside the asteroid, probably through chemical reactions in the presence of water at the dawn of the solar system. Something that would be essential to be able to generate life. Space gum. If sugars are the “hard” science news, what has captured most of our attention is what Danny Glavin, a mission co-investigator at the Goddard Space Flight Center, describes as “space gum.” The analyzes revealed a unique polymeric material, a kind of complex, sticky substance that doesn’t fit the standard minerals we’re used to. That is why its composition is now under study and its presence indicates that Bennu is not only a pile of rubble, but a chemical laboratory that is capable of create organic macromolecules that we have living beings inside us. In addition to this “gum” and sugars, the samples contained star dust that is older than our own Sun, survivors of ancient supernovae that were trapped in the asteroid’s matrix. A ‘complete kit’. With this announcement, the Bennu puzzle seems to be complete since amino acids have been found that are essential for proteins, bases to form DNA, carboxylic acids and now sugars to give energy and structure to RNA. This strongly supports the hypothesis that carbon-rich asteroids, like Bennu, acted as “cosmic delivery boys” during the late intense bombardment, seeding the early Earth with all the ingredients necessary for the life we ​​are now enjoying to emerge. It is literally an asteroid that carries all the ingredients for life as we know it. A look at the past. The stability of compounds like glucose and xylose in these samples, along with the surprising presence of ribose (which is typically very unstable), tells us that Bennu’s parent body had very specific water activity and chemical conditions shortly after the solar system formed. As confirms NASA itselfwe are facing the strongest evidence that the building blocks of biology are not a miracle exclusive to Earth, but rather common products of the chemistry of the universe.

The only photo you need to understand the scale of what Blue Origin, Jeff Bezos’ company, has just done

In the absence of bananas, there is nothing like having five human operators in the photo to understand the scale of the New Glenn rocket, whose first stage is 57 meters high and seven meters in diameter. landed successfully on a barge in the Atlantic. SpaceX has company. So far, the club of companies capable of landing their orbital-class rockets so they can be reused had only one partner: SpaceX. For a decade now, Elon Musk’s company has single-handedly dominated the reuse game, landing and taking off again up to 500 times with the Falcon 9 thanks to a reliability that is now more than routine. What you see in this photo is the breaking of that monopoly. The first successful landing of the enormous New Glenn rocket, achieved on only its second flight, demonstrates that orbital reuse is no longer a matter of a single company. Although Blue Origin, founded in 2000 by Jeff Bezos, is far behind SpaceX, it has just taken a giant leap that Bezos summarized with a Latin expression: Gradatim Ferociter (“step by step, fiercely”). As large as graceful. Unlike the Falcon 9, which measures 70 meters and can put about 22 tons of cargo into low orbit, the New Glenn stands out with 98 meters in height and a planned capacity of 45 tons. If we had not seen SpaceX catch the Super Heavy (the first stage of Starship) three times with the arms of the launch tower, it would seem more unlikely to us that a rocket like the New Glenn would be able to land gracefully in the center of a barge in the Atlantic Ocean. And without getting covered in soot. There is another fundamental detail in the photo: the rocket fuselage is clean. Unlike the Falcon 9 boosters, which return covered in the characteristic black soot caused by kerosene combustion, the New Glenn appears almost pristine. The reason is that its seven powerful BE-4 engines use methane and liquid oxygen (a combination of cryogenic propellants known as methalox). This fuel is not only more efficient and cheaper, but it burns much cleaner, facilitating inspection and reconditioning tasks for the next flight. With this landing, the New Glenn has become the first methalox rocket to successfully recover a first stage from an orbital flight, ahead of the Zhuque 3 from the Chinese company Landspace (and with permission from Starship, which also uses methalox, but has never reached orbit). Things are coming. Blue Origin’s sweet moment begins now. In an interview with Ars Technicathe company’s CEO, Dave Limp, has confirmed that the aggressive 2026 goal is to complete between 12 and 24 missions. The company has announced a launch price of about $70 million, a figure almost identical to what SpaceX charges for a Falcon 9. But the New Glenn not only competes with the Falcon 9, but also threatens to burst the market by competing directly in the league of the Falcon Heavy, but with the advantage of a unique and fully reusable first stage. As for the rocket that has landed, its next payload will not be a probe or a satellite, but the Blue Moon Mark 1 lunar module, which the company plans to launch in the first quarter of 2026 to demonstrate to NASA They are ready for the moon race.

The origin of the oceans on Earth has always been somewhat mysterious. Now we are clearer how it happened

A team of scientists, analyzing the tiny and invaluable samples of the asteroid Ryugu brought to Earth by the Hayabusa2 missionhas made a discovery that shakes our understanding of water in the early solar system. The discovery, published in the prestigious magazine Naturereveals that liquid water flowed in Ryugu’s progenitor body more than a billion years after its formation. Something that changes our paradigms. Contradiction. This new discovery contradicts the belief that water activity on asteroids It was a phenomenon exclusive to the first moments of the history of our solar system. And most importantly, it could force us to recalculate how much water these bodies brought to a young Earth. Many doubts. The story of how our planet became an aquatic world still has gaps. One of the most accepted theories is that carbonaceous asteroidsformed from ice and dust in the confines of the Solar Systemacted as a cosmic “water delivery” service for the inner planets. JAXA’s Hayabusa2 mission has provided us with a unique opportunity to study this process by bringing back 5.4 grams of pure material from the asteroid Ryugu. And this is very important. While meteorites that fall to Earth are altered by contact with the atmosphere and environment, the Ryugu samples are a near-perfect time capsule. This is because a perfect record of water activity is preserved within it, proof that fluids moved through its rocks sooner than could be expected. This is something fundamental that changes the way we think about where the water in asteroids comes from and ends up on our planets. Isotopic clock. To reach this conclusion, the team turned to a “radiometric dating“based on isotopes: the radioactive decay of Lutetium-176 into Hafnium-176. Something that can be similar to the ‘Carbon-14’ test that is better known. In an object as old as Ryugu’s father, you would expect the proportion of these elements to follow a predictable line, known as isochronewhich dates back to 4,565 million years ago. But Ryugu’s data did not fit these models. The samples deviated from that ‘reference’ line showing an excess of hafnium (or a deficiency of lutetium). In order to understand why, it was first ruled out that it was due to accelerated disintegration or the effects of cosmic radiation. This made the conclusion point differently than that, at some point, a liquid ‘washed’ and took away some of the lutetium from the asteroid’s rocks. The reasons. The event that triggered this late flow of water was, most likely, a violent impact. While the first aqueous activity, which occurred in the first seven million years of the solar system, was driven by heat from the decay of radioactive elements, this second event was different. Specifically, we are talking about an impact on the body of Ryugu’s ‘father’ that would have generated enough heat to melt the ice that had remained frozen inside for eons, and at the same time, would have created fractures in the rock that emerged as channels for liquid water to flow. On the Primitive Earth. If asteroids like Ryugu’s father were able to retain not only hydrated minerals but also large amounts of water ice for more than a billion years, their potential to ‘water’ other planets is much greater than expected. Current models of the formation of terrestrial planets could be underestimating the amount of water contributed by these bodies. According to this study, Ryugu-like planetesimals could have entered two to three times more water into Earth than is commonly estimated. This would have direct implications on our understanding of the origin of the oceans, the atmosphere and in general the conditions that made it possible for us all to be living here.

Millions of users used the legendary Windows XP key “FCKGW-RHQQ2-YXRKT-8TG6W-2B7Q8”. Now we know its origin

Many users – and I included myself – almost knew by heart the activation key for Windows XP“FCKGW-RHQQ2-YXRKT-8TG6W-2B7Q8”. With it it was possible to install a valid and official copy of the operating system that Microsoft launched in October 2001, but until now it was not known where that key had come from. Now we know. what has happened. Dave W. Pullmer is a famous engineer and developer who worked his entire career at Microsoft and who, in addition to being in charge of the task manager or ZIP folders, had another task: working on the first version of the Windows Product Activation (WPA) system. Precisely that allowed him to know from the inside what happened with that activation key, and He told that story on Twitter. It was not stolen, but leaked. As Plummer explains, no one hacked Microsoft or its systems to obtain it, nor did they manage to steal it. There was actually a mistake on the part of the development team, and a “disastrous leak” occurred. There were no social networks, but it didn’t matter. That leak ended up going viral and millions of users found out about the trick almost immediately, something surprising considering that conventional social networks did not yet exist. There was no need: a warez (pirated software) group called “devilsOwn” released the key five weeks before the launch of Windows XP, and the key was published on IRC, online forums, Usenet groups, warez websites and especially P2P applications such as eDonkey or KaZaA. How activation keys were calculated. The WPA system generated a key that was based on each user’s hardware: “the identifiers of the CPU, RAM and other components” were taken into account, and were sent to Microsoft along with that activation key to be validated. If errors or suspicious keys were detected, that installation was labeled as pirated. Master key. But FCKGW-RHQQ2-YXRKT-8TG6W-2B7Q8 was a valid volume license key that became part of the “white list” that the key validation system had. If that key was used, the servers assumed that it was an enterprise volume license, and that “there is no need to call home.” Thus, when installing Windows XP, users simply had to answer “Yes” when asked if they had an activation key, they entered the famous key and thus avoided checking it. It was like having a master key. You could even update XP. When using this activation key, the operating system started fully functional and without activating small user warning mechanisms such as watermarks or a 30-day countdown. It was even possible to overcome the controls that were applied to receive updates. Although Microsoft detected and banned activation key, new illegitimate patches and “cracks” appeared who managed to make this activation mechanism persist for years. Now you couldn’t use it. As Plummer explains, you could technically still use it on old Windows XP installation disks if you could find one, but Microsoft’s own servers that handled the validation process were disabled years ago. And even if it wasn’t, the key ended up being part of the blacklist of prohibited activation keys, meaning you couldn’t use it to validate a legitimate copy of Windows XP.
