The mission in Caracas revealed that the best kept secret in the US is not a drone: it is called DAP and you will not see it in the movies

The capture of Nicolás Maduroby US forces has not only meant a political earthquakebut rather he explained with almost surgical clarity the media type that the United States reserves for maximum risk direct action operations. In fact, the famous Night Stalkers of Washington’s Army made it clear that the drone is still in second place. Designed to enter where no one else can.Qbecause the first place is reserved to DAPthe MH-60M Direct Action Penetrator, the most aggressive and specialized variant of the black hawk operated by the 160th Special Operations Aviation Regiment, the Night Stalkers. Venezuela was, in every sense, the ideal setting for this device: a hostile urban environment, potential air defenses, the need for rapid insertion, armed escort, precise fire and absolute coordination with assault teams. Although armed versions of the H-60 ​​exist in several countriesthe DAP of the 160th SOAR represents the maximum degree of maturity of the concept, far above even those already sophisticated MH-60 transportation of the regiment itself. It is not a helicopter adapted after the fact, but a platform conceived decades ago, operational at least since 1990to accompany special forces where error is not an option. In Xataka Neither drones nor fighters nor elite soldiers: the US entered Venezuela disguising a 20th-century tactic as technology. XIX Modular firepower. The heart of the DAP is its ability to combine the punch of an attack helicopter with the flexibility of a special operations device. The current configuration of the MH-60M incorporates modular short wings with one or two heavy points per side, capable of carrying a mix of 70mm missiles,AGM-114 Hellfireair-to-air missiles Stinger ATASheavy machine guns GAU-19/B .50 caliber and M230 cannons 30 mm, the same model used by the AH-64 Apache. Added to this are two 7.62mm miniguns which can be fixed in a frontal position to maximize the volume of fire during low-altitude passes. The introduction of APKWS II guided rockets laser has added surgical precision that allows beat specific objectives in dense environments without resorting to more destructive ammunition. All this arsenal is integrated into a platform that maintains a key advantage: its dual character. In a matter of hours, the DAP can return to a transport configuration, a critical quality for unpredictable operations where the same helicopter may need to escort, attack and evacuate in a single mission. Penetrate at night and fly low. Beyond weapons, what defines the MH-60M DAP is its ability to reach the target without being detected and survive once inside. The aircraft shares with the rest of the 160th SOAR fleet an avionics suite designed for extreme night flight and nap-of-the-earth profilesliterally skimming the terrain even in adverse weather conditions. They counted the TWZ analysts that the terrain tracking and avoidance radar, in its most modern version AN/APQ-187 Silent Knightallows the crew to fly blind to any other conventional helicopter, while the electro-optical and infrared system AN/ZSQ-2 provides identification, laser designation and video in real time. Systems like the Degraded Visual Environment Pilotage Systemwhich combines cameras, LIDAR and terrain databases, allow operating in dust, smoke, heavy rain or fog, common conditions in a night urban assault. And more. This set of sensors not only facilitates navigation, but also allows the DAP to fight at very close range, executing the classic combination of strafing and rockets that has been seen in videos of the Venezuelan operation, erroneously attributed in some cases to AH-1Z helicopters of the Marines. {“videoId”:”x9cqyyg”,”autoplay”:false,”title”:”A KEY of 8 ZEROS PROTECTED the WORLD from an unauthorized NUCLEAR ATTACK”, “tag”:”Webedia-prod”, “duration”:”457″} Invisible shielding. Plus: If there is something that distinguishes the 160th SOAR helicopters, it is their obsession with survival. The MH-60M DAP is covered by a genuine self protection bubble which integrates infrared, radar and laser missile warnings, active electronic warfare systems, chaff and flare dispensers, and directional laser countermeasures such as the CIRCM systemcapable of blinding infrared guided missile seekers in mid-flight. This entire ecosystem is interconnected– Detection of a threat can automatically trigger jamming, countermeasures and evasive maneuvers without direct crew intervention. Added to this is a complete electronic intelligence system and data links that allow us to know the location of emerging threats and receive information from other platforms in real time. The result is one of the most difficult helicopters in the world to shoot down, especially in night and low-altitude missions. In Espinof Hugh Jackman presents the extraordinary trailer for his new film, where he becomes one of the most legendary characters of all time The coming war. The operation in Venezuela also has hinted the immediate future of this type of platforms. The US Army has been experimenting for years with the so-called lpunched effectsdrones launchable from helicopters capable of attacking, interfering or deceiving defenses tens or hundreds of kilometers away. Although its operational use has not been officially confirmed, there are indications that the MH-60M DAP could use them for the first time in combat during this mission, expanding its effective range and reducing direct exposure to enemy fire. Added to all this is the ability to refuel in flight using a telescopic probe, normally from MC-130J aircraftwhich extends the helicopter’s radius of action to limits imposed more by human resistance than by fuel. In short, the MH-60M DAP is consolidated as the version more armed and protected of the Black Hawk ever built, a tool tailor-made for operations like the one in Venezuela, where perfect coordination between helicopters, special forces and air support decides success or failure. Far from being a simple armed escort, the DAP is the closest thing to an integral force multiplier, difficult to replace by conventional means and a central piece of the way in which the United States today executes its most delicate missions.

Taking a train to go to work in Barcelona or Girona has become an impossible mission

Finding an AVANT train ticket to move around Catalonia has become quite a risky mission. Thousands of people who travel daily from Girona and Lleida to Barcelona face the impossibility of finding this type of ticket less than two weeks in advance. The high demand has overwhelmed the supply of places on high-speed services, forcing users to plan their trips weeks in advance or risk being left without transportation. The problem in figures. Demand for AVANT services has skyrocketed in recent years. According to Renfe data that share elDiario, in 2024 the Figueres-Barcelona line transported 1.52 million passengers, 43% more than in 2022. From Lleida, the increase was even more pronounced: 488,000 travelers in 2024, 65% more than two years before. This exponential growth has exceeded the capacity of the current infrastructure, creating a bottleneck that especially affects peak demand times. Why are AVANTs collapsed? The phenomenon has several causes. The main one is 50% bonus in the price of the passes implemented in 2022, which has turned these trains into an accessible alternative to the private vehicle. Added to this is the deterioration of the Rodalies and Media Distancia service, plagued by incidents and delayswhich has pushed many users towards high speed. Travel times are also a more attractive factor: 40 minutes from Girona to Barcelona compared to an hour and a half by conventional train, or an hour and a quarter from Lleida compared to more than three hours by Rodalies. The odyssey of getting a ticket. Daniel Blay, who usually takes the Girona-Barcelona train, account to elDiario that “on Monday of each week I try to reserve all the tickets for the following week, because if not you will run out.” For some critical schedules, such as the 7:25 train from Girona, there are no places available “within ten days or two weeks.” From Lleida, the situation is similar. Kevin Bruque, spokesperson for the Avant Catalunya Users platform, explained to the media that “you only find 15 days in advance to get a ticket if you are lucky.” Delays exacerbate chaos. In addition to the shortage of places, users report a significant increase in delays. More than 550 users have a Telegram group for the Girona line, coordinated by Blay, in which they already They have documented 292 delays longer than four minutes only in November 2025. Many of these delays occur on return journeys in the afternoon, when trains accumulate delays from long-distance services from Seville, Valencia or Madrid, according to the media. To solve this problem, many travelers demand shuttle trains that do not depend on connections with other routes, they assured from elDiario. The official response is insufficient. Renfe recognizes that the offer has grown from 1.4 million seats annually in 2022 to 2.4 million in 2024, but users maintain that frequencies have not been added during peak hours, where they are most needed. The operator attributes the delays to the improvement works on the Catalan railway network, especially in the future Sagrera station. However, passengers consider that these explanations do not solve the underlying problem: the need for more trains and more seats. More solutions. Among the urgent measures proposed by several of the traveler platforms, the 50% bonus should be maintained beyond 2025, since its disappearance would make the cost unaffordable for many workers and students. On the other hand, they demand an increase in frequencies and available seats. CCOO has proposed reusing Avlo service trains that are out of use to double the capacity of AVANT, an initiative that the Generalitat has included in its railway strategy under the name Catav, according to share the ARA Newspaper. In the case of Lleida, users also claim to be able to access the empty seats on the Madrid-Barcelona AVE trains that stop in their city, something that is currently only possible on four frequencies. What happens now? The Minister of Territory, Silvia Paneque, advertisement last week that the Government is working with the Ministry of Transport to improve AVANT services in Girona and Lleida. CCOO confirms that the ministry has agreed to study the proposal to reuse Avlo trains. It remains to be seen if the proposals end up reaching a solution that clarifies all this chaos.

There is a Facebook group available 24 hours a day that even doctors attend. Your mission: identify poisonous mushrooms

“Hello, I have a human patient with late-onset gastrointestinal symptoms after ingesting these mushrooms.” This is how one of the many messages you receive in ‘Poisons Help; Emergency Identification For Mushrooms & Plants‘, a Facebook group formed by experts in the identification of poisonous plants and mushrooms. They are available 24 hours a day and not only receive consultations from individuals, but also doctors and veterinarians. ID. There are more than 100,000 species of fungi, of which more than a hundred are poisonoussome even mortal. And the same thing happens with many plants. If a person or animal ingests one of these by accident, it is crucial to identify the species to see what steps to take. However, distinguishing these species is not an easy task; in-depth knowledge of botany and mycology is required. In 2018, several experts founded a Facebook group to help identify poisonous species in emergencies. And they are extremely effective. For emergencies only. When you enter the group, a message appears with the rules for posting. The first thing they make clear is that it is a group for emergencies, that is, you can only post if a person or animal has ingested the mushrooms. If someone has a question because they are curious to know details about a specific specimen, there are other groups for that. They also have a warning for trolls: “People come here at scary times for immediate life-saving help, please don’t make jokes, judge or criticize. This is not the place to test your sense of humor or correct others.” Strict rules. For the group to be effective, in active cases no one is allowed to comment other than the administrators themselves or the people who have reported an emergency. It is necessary to provide all possible data: location, amount ingested, time since ingestion, photos of the specimen, weight of the person or animal that ingested it, etc. Doctors and veterinarians. Many of the posts are made directly by professionals who have a patient with problems after ingesting an unknown mushroom or plant. Most are veterinarians, but there are also many cases of doctors with human patients in the same situation. Even there have been cases in which the poison center itself has been the one who recommended going to the group for identification. Recognition. In addition to being a source of consultation for professionals, its work has also been recognized by associations such as the American Academy of Clinical Toxicology, which last August invited them to give a talk in one of his conferences. Among the group administrators There are mycologists, botanists and also amateur hobbyists. Cover image | Vladimir Srajber, Pexels In Xataka | Sex is deadly for many males.

In his mission to follow the movements of North Korea, South Korea has decided to bet on an advanced steering wheel

In South Korea, the surveillance of heaven It is a constant task that is never terminated. Missile tests and the use of low flight drones The need to strengthen detection systems has highlighted by the north. Radars on land, conditioned by the country’s geography, do not always offer the necessary coverage against threats that seek to go unnoticed. To respond to that challenge, Seoul has decided to bet on a new generation of Early alert planescapable of expanding surveillance and ensuring more stable control of your airspace. It is not just about incorporating technology, but ensuring that the country has sufficient means to anticipate any scenario. The search for a new early alert plane It started in 2020when the Defense Procurement Agency (DAPA) approved the second phase of its AEW & C program. By then, South Korea already had four E-737 Peace Eye acquired from Boeing in 2006 and delivered in 2012, but the experience had made it clear that they were not enough. Parliamentary documents revealed in 2019 indicated Availability problems and technical failuress that prevented maintaining the planned patrol rate. To that limitation was added the pressure of an increasingly complex strategic environment, marked by the expansion of North Korean arsenal. A jump in the air surveillance strategy Seoul has opted for an unusual combination until a few years ago: an executive reactor Bombardier Global 6500 equipped with radar The/W-2085 developed by Elta. This system, with active electronic exploration antennas on the sides and additional sensors in the nose and tailallows to monitor in all directions promising a much greater scope than that of conventional radars. With this model, the country is looking for a more compact platform and with operational costs contained compared to larger solutions. The contest was marked by a struggle between two proposals that started from the same base plane, the 6500 global. L3Harris offered to integrate it with the radar the/W-2085, while the European Saab presented its globaleye solution, equipped with the radar Erieye Extended Range. Dapa’s evaluation concluded that there were no major differences in technical performance, but in other aspects. As the agency explainedthe American proposal received more points in operability, maintenance costs and contribution to the local industry, while the Swedish firm stood out in price and contractual conditions. Conceptual Image of Global 6500 for South Korea According to Dapa, the approved budget amounts to 3.87 billion wones, about 2,820 million dollarsand contemplates the incorporation of four planes until 2032. The goal is to have permanent patrols capable of monitoring the national airspace without interruption and coordinating the response in case of crisis. Deliver planning up to that horizon will progressively integrate aircraft in the operations of the Air Force. An E-737 Peace Eye in the United States The industrial component presumably had a relevant weight in the decision. L3harris has been supplying equipment to the South Korean armed forces, from electro-optical and infrared surveillance systems to safe communications and night vision devices. The company has an authorized service center in the country, which reduces maintenance times and simplifies logistics in case of breakdowns. The 6500 global is expected to reinforce the air defense of the Asian country. These devices will be integrated into the grid national Istarconnecting combat sensors and units to generate a complete image of airspace. Its main mission will be to detect intrusions and coordinate the immediate reaction, but its regular use is also contemplated in periods of calm to maintain training and preparation of crews.

Openai is demonstrating to be able to overcome the goal in virality. His mission was not supposed to be that

Openai has launched Sora, its social application with which it invites users to create short videos generated by AI and then share them on that network. The product has turned out to be an immediate viral success, extremely simple to use and highly addictive. So much that he has totally left the company that theoretically dominated this segment perfectly. What happened. Traditional social networks are being filled with videos generated with Sora 2the new and striking video generation model by IA. The expectation seems even to have exceeded what I already generated I see 3Google’s model, but it is that Openai has not been confirmed to offer this model, but has accompanied it with a mobile application that is actually a new social network. One in which all the content is those videos and images generated with Sora. Vibes goal, ridiculous. The first surprise is not so much that the application has been successful, but has left Meta Vibs in an absolute background. The company led by Mark Zuckerberg announced a few days before of Sora 2 its new social network totally dedicated to the content generated by the only days before OpenAi, but the impact, at least in terms of the “noise” generated on social networks, is minimal. There are those who criticize that Vibes is “half cook” and it’s “obtuse” for the difficulty when using it in front of Openai. What Altman’s company has achieved is to win in this New career for the economy of attention. OpenAI strategic turn. But the really remarkable thing about this launch is that it seems to raise a strategic OpenAI turn. The company led by Sam Altman has been promising that We will have an AGI in a few thousand days. That diffuse promise contrasts with a reality: GPT-5 is a good modelbut does not represent a specially striking leap regarding the state of the current art. And given that slow evolution and progression, the solution seems to be to offer AI toys. They already did it with the Studio Ghibli Style Imagesbut Sora 2 and Sora’s app go further. They are AI toys … dangerous. Ai Slop. This model contributes even more to that future in which the “spleen generated by AI” (AI Slop) becomes the most widespread type of content in social networks and the Internet. But there are also (among others) a potential and gigantic privacy problem with Sora’s “cameos”, which can end up helping the generation of deepfakes to shoot. The future was a meme factory. That viral success of the app Sora makes the line be blurred between creators and content consumers and does more than ever who consume it end up creating it and realiment the phenomenon. And that makes AI a meme factory, and not a technology that helps us solve real problems. It is true that there are sectors that are taking advantage of it in professional fields, but the danger is that the focus of AI ends in entertainment and content that can also end up being toxic. The Killer-App of the AI ​​was to create videos. Chatgpt and AI continue without having a “Killer App” definitive practice: they help (more and more, true) to programmers, summary documents and rewrite emails, but for now the current models seem to fall short in their promise to revolutionize our world. Openai has managed to market technology better than anyone, but not because cancer heals or solves economic inequalities: he has caused anyone to create absurd and irresistible videos. The chatgpt of the video has arrived. The truth is that despite whom despite, this is a unique time in the frantic evolution of AI. If Dall-E and Chatgpt were those inflection points for AI that generated images and text respectively, I see 3 and Sora 2 have shown that the video generated by AI is prepared for the mainstreamfor mass consumption, although its long -term value may be questionable. Of course its use as the center of a new era of entertainment is. In Xataka | Differentiating the AI ​​content on the Internet is increasingly difficult.

We knew that the Dart mission changed Dimorphos’ trajectory. What we did not know is that its form also changed

At the end of September 2022, the Dart mission (Double Asteroid Redirection Test) It made historyInterestingly, stamping against an asteroid. The milestone was not on the impact itself but on achieving with him slightly divert the trajectory of an asteroid, Dimorphos. The expected and the unexpected. In the almost three years since then, we have been learning New details on the effects of Dart’s impact on Asteroid Dimorphos. Now we know, for example, that Dart not only managed to divert the orbital trajectory of the space rock; He also achieved with his impact to make the asteroid orbit deform significantly What happened. The asteroid, explained the team, initially had an oblate form, that is, flattened in the poles, such as the earth, “the shape of a hamburger.” After the impact, Dimorphos became a rather prolata, elongated in the poles, like a rugby ball. “For the most part, our predictions pre-impact on how Dart would change the way Didymos and her moon (Dimorphos) move in space were correct,” ” explained in a press release Derek Richardson, who led the analysis of the effects of the probe. “But there are some unexpected discoveries that help provide a better image on how asteroids and other small bodies are formed and evolved over time.” Tumbos. According to the team that analyzed these orbital changes, the impact would have made dimorphs pass from a state of equilibrium with its main asteroid Didymos similar to that of our moon with the earth, to an irregular one. That is, dimorphs always gave the same face to Didymos, at least Until Dart arrived. Now the system is out of its alignment, Richardson pointed out. This implies that it can stagger changing orientation, even ending up “tumbos”, rotating chaotically and unpredictable. Asteroid formation. Thanks to studies such as the one conducted by Richardson and the team, we can access new clues about the formation of asteroids. As explained by the team, the impact released small rocks that remained in the orbit of the asteroid system. These contributed to altering the orbital movement in the system, but these changes in the gravitational balance do not seem to have altered the form of didymos. This implies, the team added, that the main asteroid of the system was rigid and firm enough to maintain its form after the formation of its moon dimorphs. The details of the work were Published in an article In the magazine Planetary Science Journal. Hera’s turn. The scientific community now has new eyes on the Didymos system, those of Herathe mission of the European Space Agency (ESA) aimed at monitoring the system and collect new data In situ. If everything continues as planned, Hera will begin in October a trip that will lead her to reach the double asteroid towards the end of 2026. The data compiled by Hera They will allow an even more exhaustive analysis of the impact of the Dart mission. This in turn will be what gives us key clues that allow us to plan missions that protect our planet from the asteroid shock.

one million terabytes and 24,000 nvidia chips for a key mission

In an increasingly digitized world and where artificial intelligence (AI) is transforming the way we work, investigate and relate, the supercomputing has established itself as the rod of measure technological power. It is a strategic resource that allows us to accelerate advances in science, innovation and defense. Not all super -taders play in the same league. Frontierof the United States Department of Energy, marked a milestone in 2022 by becoming the first to officially overcome the exaescala barrier, with 1,102 Exaflops in the Benchmark HPL. To that achievement they joined later The Captain and Auroraalso on American soil, consolidating its leadership position on paper. In the case of China, the information remains opaque, With very few public data about the status of their projects. Europe, however, just moved. Your first superorous to exaescala is already underway: Jupiter. Installed in the Jülich Supercomputing Centerin Germany, one of the most important advanced research poles of the continent. Jupiter is driven by the platform Nvidia Grace Hopper And Evidan xh3000 Bullsequana architecture is based on a liquid -refrigerated system designed to squeeze efficiency and performance. It is expected to reach up to 90 exaflops in artificial intelligence loads. Their applications will be diverse: from climatic research to neuroscience and quantum simulation, placing Europe in a new calculation capacity league. An inauguration with historical air September 5 The official inauguration ceremony in Jülich took placewith the presence of German authorities, European and leaders of the technology industry. German Chancellor Friedrich Merz presented him as a Pioneer project for Europe. “With Jupiter, Germany now has the fastest supercomputer in Europe and the fastest room in the world. Open completely new possibilities, from the training of AI models to scientific simulations.” In the Top500 list, Jupiter already appears as the fourth Most powerful supercomputer in the world, only behind the Captain, Frontier and Aurora in the United States. The European Union stands outIn addition, what works entirely with renewable energyby hiring green supply on the German network, and that its Rack Jedi leads the Green500 energy efficiency classification. The figures behind Jupiter To understand its magnitude, just review some technical data: 24,000 superchips nvidia gh200 grace hopper 51,000 network connections with infiniband quantum-2 technology Storage capacity close to an exabyte Modular installation with 50 specialized containers Maximum consumption of 17 MW, equivalent to about 11,000 homes A rack called Jedi leads the World Energy Efficiency Classification Why is it relevant to Europe Europe had been behind in the supercomputing career for years, with a landscape dominated by the United States. JUPITER offers researchers, companies and academic centers direct access to a top -level machine without depending on external resources. This means forming their own talent, consolidating experience in the management of these systems and reinforcing technological sovereignty at a time when artificial intelligence and calculation capacity have become strategic issues. Concrete applications The first projects already selected show how far a supercomputer of this category can go: Climate: The ECMWF works with a kilometer scale simulations, capable of representing extreme storms and feeding the Destination Earth project, whose objective is to build digital twins of the planet European: The Trustllm consortium trains language models in multiple European languages ​​for industrial and scientific applications Neuroscience: With the arbor simulator, neurons behavior will be modeled at the subcellular level, key to developing therapies against diseases such as Alzheimer’s Quantum: JUPITER aims to exceed the 50 -QBITS record in simulation, a relevant step towards quantum practical computing Astrophysics: The Max Planck Institute will use it to study cosmic reion, the period in which the first stars and galaxies emerged Particle physics: The University of Wuppertal will increase the resolution of its calculations on the Mon, which could open the door to new discoveries Video models: The University of Munich explores compression and dissemination architectures to advance applications that go from medicine to autonomous driving Multimodal models: The University of Lisbon Scale open and multilingual models, integrating different fields of science and automatic learning Access and future Researchers may request access to the system in calls that will be held twice a year. At the moment, there are already 30 projects underway. The expected useful life is at least six years, which guarantees continuity and stability in a land where technological cycles are increasingly fast. A strategic movement Jupiter is not just a technological achievement. It is a strategic commitment to provide Europe on their own capacity in an area where part of the future of artificial science and intelligence is played.

His next mission for this year is to divert an asteroid

We may not finally need Bruce Willis, but Armageddon It is no longer a movie as unlikely as it seemed. After the United States managed to divert an asteroid for the first time in history, China prepares to launch its own planetary defense mission this year. Of course, with something that NASA did not have: a second probe to record everything live. A little context. In 2013, NASA and the European Space Agency created the AIDA program to demonstrate the asteroid deviation close to Earth. He NASA Dart Kinetic Impactor It would crash at high speed over a small asteroid called Dimorfo, and the AIM orbiter developed by that would record the event live to measure the effects of impact. ESA ended up abandoning the development of AIM due to the lack of financial support of the Member States. But NASA continued with the development of Dart and, on September 26, 2022, the asteroid successfully diverted, with a small Italian Cubesat (Lyciacube) as the only witness of the feat. The hera mission of ESA, AIM spiritual successor, is traveling to Dimorfo to take data From his arrival in December 2026, four years after the impact. Now it’s China. Although NASA-that collaboration did not materialize as conceived, China has its own version of AIDA. For now it is known as “experimental test of the asteroid defense system close to Earth”, but is very close to becoming a reality (probably with a less aseptic name). Wu Weiren, designer of some of the most important missions of the Chinese space program, commented at a conference in Heféi that the launch is scheduled as this year aboard a CZ-3B rocket. If it succeeds, the mission will make China the second country in the world deliberately against an asteroid to modify its orbit. And what is better: with a second probe loaded with sensors to record the live impact. Two ships instead of one. Unlike NASA’s mission, which sent a single Kamikaze probe with the Italian Cubesat inside, China’s plan contemplates the launch of two ships: an impactor and an observer that will make an exhaustive recognition. As for the asteroid, The chosen one is 2020 pn1located in an orbit of horseshoe to dozens of millions of kilometers from the earth. As details Wu Weirenthe observer will come first to map and obtain precise physical data. Shortly after, the impact ship will collide at high speed against the asteroid under the watchful eye of the observer, in addition to a combined network of telescopes on land and space. The objective is to accurately measure changes in orbit, morphology and material expelled by the clash of the ship, to evaluate the effectiveness of the impact. The goal is even more modest than that of Dart: produce an orbital deviation of between 3 and 5 centimeters. More difficult than it seems. The ship will have to travel for months, adjusting its course to hit an object of just a few hundred meters in diameter, with a minimum margin of error. To which you have to add uncertainty about the composition of the asteroid: it is not the same to collide with a solid rock than against an amalgam of loose rubble. The challenge is immense. “How to hit a fly from tens of millions of kilometers away”, PUBLISH THE GLOBAL Times. But NASA showed that it is possible, and now China has the opportunity to confirm that humanity is able to defend itself from one of the greatest existential threats faced by the Earth: the impact of a nearby object. The first test of a long -term plan. This mission is just the first piece of an ambitious puzzle with which China plans to establish a complete detection and defense system against asteroids. The country already has a land surveillance network, which includes the telescope of the Purple Mountain Observatory and the “China Compound Eye” project, a set of radars capable of obtaining high -precision images of asteroids to millions of kilometers. The plan is to complement this terrestrial network with a fleet of observation satellites in space and have a catalog of options to act as a threat is detected. It is not science fiction, but a real and urgent plan. In early 2025, in the midst of the growing concern for asteroid 2024 YR4, China opened a recruitment process In search of experts in astrophysics and international cooperation to create their own planetary defense force. Space muscle demonstration. This new mission comes at a time when China’s space program advances at a dizzying pace in contrast to NASA’s scientific cuts. China’s experience in handling deep space is growing, and has already achieved milestones that the United States does not possess, such as bringing samples of the hidden face of the moon. In May of this year, China also launched the Tianwen-2 probe, which is directed to the quasi-satellite Kamo’oalewa to collect the first samples of this peculiar object, A probable fragment of our moon. The samples would arrive to the Earth in 2027. Subsequently, the ship will continue its trip to a cometr of the main belt, in the farthest mission ever undertaken by the country. The next step: bring the first samples of Mars with Tianwen-3, something that seems to China will also get Before the United States and Europe.

An Voyager 2 mission review has revealed that Uranus is not as described

Uranus, the planet that orbits side, has always been the weirdo of our solar system. Since NASA’s voyager 2 probe survived him in 1986astronomers have dealt with a disconcerting mystery: unlike their gaseous Jupiter, Saturn and Neptune, Uranus seemed not to have an important internal heat source. It was, in appearance, an inert and energetically dead world. But that idea has just jumped through the air. A little context. In January 1986, the Voyager 2 probe became the first and only ship to visit Uranus, giving us the most iconic images of the planet and the data that laid the foundations of everything we know about him. One of the most important was its energy balance, the heat it emits with respect to the sun. The giant planets have an immense mass, so they retain a considerable amount of the heat of their formation and release it over billions of years. This internal heat flow is evident in Jupiter, Saturn and Neptune. However, the Iris instrument of Voyager 2 told a very different story about Uranus. According to a 1990 study, the planet issued an almost identical amount of energy to what it received from the sun: the internal heat flow was statistically indistinguishable from zero. Uranus thus became the anomaly of the Solar System: an ice cream giant that, for some reason, had cooled much faster or formed in a completely different way from the other planets. I wasn’t dead. Nor of Parranda. A New study led by researchers from the Houston University It has finally resolved the mystery. After analyzing decades of data, scientists have shown that Uranus does emit more heat than he receives from the Sun. It is not the inert planet we thought, but a dynamic world with an internal engine That, although modest, is very present in the energy balance. The error was not in the measurements of Voyager 2, but in the interpretation of a single snapshot over time. This is where the new study led by Xinyue Wang and Liming Li, from the University of Houston. Instead of based only on the overflow of 1986, his team compiled and analyzed data from a much longer period (from 1946 to 2030), covering almost a complete orbit of Uranus, which lasts 84 terrestrial years. Uranus is a planet of extremes. Its rotation axis is inclined 97.7 degrees, so it basically rolls on its orbit. Combined with a remarkably long orbit, it causes extreme stations that last about 21 years each, with a hemisphere bathed by continuous sunlight while the other remains in an icy darkness. The researchers discovered that this seasonal cycle is the key to everything. The solar energy that absorbs the planet is not constant, but varies significantly throughout its year. The 1986 analyzes, made near the winter solstice of the northern hemisphere, did not capture the complete image. By averaging the energy balance throughout the orbit, the results are unequivocal: Uranus consistently emits 12.5% more energy than he receives from the sun. Not so weird bug. Uranus now fits much better in the formation models of giant planets. It has an internal engine, although it is weaker than that of its neighbors, which suggests that its evolution was more similar to that of the rest of what was thought. This finding not only changes our understanding about how giant planets are formed and evolved, but also arrives at the right time, when Both NASA as China prepare missions To visit it. If the question is why Voyager 2 obtained such a misleading image of the planet, the answer is simply bad luck. In the days before the 1986 overfather, the Sun bombed Uranus with An unusually powerful geomagnetic storm. This phenomenon compressed the magnetosphere of the planet, which caused the ship to capture data in a day of extreme conditions.

The exomars mission already accumulates 20 years of calvary and bad luck

Mars seems to have a special online to the European space agency and, more specifically, to the exomars mission and his Rover Rosalind Franklin. What promised to be a pioneer mission for Europe in the search for past life on the red planet has become a true technological and geopolitical calvary, a saga of misfortunes that leads to ask if the rover will not simply be cursed. From NASA to Russia. The exomars odyssey It started two decades agoin 2005, with the aim of launching a rover to Mars in 2011. Initially conceived in collaboration with NASA, the mission suffered a first capital setback in 2012, when the US agency, due to the cost overruns in projects such as the James Webb space telescope, decided to retire. Nor was the European prominence of the mission funny. This first jug of cold water forced ESA to look for a new partner to desperate. The Russian Space Agency Roscosmos. Russia would provide the proton rockets for the two phases of the mission and a crucial element: the Kazachok descent module that would be in charge of the Martian landing of the rover. A second setback. The first phase of the mission, launched in 2016included the Trace Gas Orbiter probe, which operates successfully in the Martian orbit. Also the Schiaparelli landing module, designed to test “mooring” technologies. Schiaparelli crashed into the surface because he misunderstood the accelerometer readings: he mistakenly assumed that he had landed and fired the roof and parachute early. On Earth, the launch of the Rover, scheduled for 2018, was postponed to 2020 for problems with The parachutes and delays in the delivery of components. Then, the Covid-19 pandemia He added more delays, pushing the launch window at 2022. And then, war. The Rover was baptized ‘Rosalind Franklin’ in honor of the British crystallographer whose x -ray diffraction images were fundamental to reveal the double helix structure of the DNA. When everything seemed (finally) on track, with the rover ready for a few months of takeoff, the Russian invasion of Ukraine in February 2022 He dynamited collaboration. ESA, in an inevitable decision, suspended cooperation with Roscosmos, leaving Rosalind Franklin orphan of a pitcher and, above all, of landing platform. A devastating blow. Light at the end of the tunnel. Baptized ‘Rosalind Franklin’ in honor of the British crystallographer whose X -ray diffraction images were fundamental to reveal the double propeller structure of the DNA, the rover did not raise head. But that decided not to throw in the towel. Member States pledged new financing in the mission and ESA chose to develop a European landing platform. Thales Alenia Space was selected as the main contractor in April 2024 with a contract of 522 million euros, but it is Airbus Defense and Space the one that will be in charge of design and construction of the landing module, which, ironically, keep a great resemblance With Russian Kazachok. And now what. When light was finally seen at the end of the tunnel, The budget proposed by the White House For NASA it seems to leave out the contribution of the US agency in the European Rover. According to Eric Berger, from Ars Technica, in addition to the Mars Sample Mission Return of Return of the Red Planet, in which Europe also participated, The contribution of NASA was disappearing in the European Rover Rosalind Franklin. It was a modest, but crucial contribution to the mission: Plutonium -based RHU heater. For now, the launch date of the Misión Exomars and the Rover Rosalind Franklin remains scheduled by the end of 2028, with A landing in the Martian plain Oxia Planum planned for 2030. A long trajectory to avoid the season of global dust storms on Mars. Rover Rosalind Franklin will carry its drill capable of drilling up to two meters under the surface, where possible biofirms would be protected from radiation.
