NASA is so obsessed with defeating China that, instead of delaying its next flight to the moon, it has advanced it

by

It seemed like him Artemis program It was intended to be delayed again and again, but NASA’s last movement betrays the enormous geopolitical pressure of the moment. Artemis II, the mission with which the United States will return to lunar orbit for the first time in more than 50 years, is no longer scheduled for April 2026. They have advanced the launch window to February 5. A declaration of intentions. This two -month advance is not a simple recalibration of the calendar of the Artemis missions. It is the NASA’s evening response to the feeling that the United States is staying behind the Methodical Lunar Program of China. NASA recognizes that “there is a desire that we are the first to return to the surface of the moon,” and Artemis II is a first step. The mission without a launic had been postponed from 2024 to 2025, and then to “not before April 2026”. Now the launch window opens two months before: on February 5, 2026, leaving as a deadline “not later April 2026”. Solving the ghosts of Artemis I. To understand why this advance is significant, you have to remember why Artemis II was delayed first. The main cause was the thermal shield of the Orion ship. After the return of the mission without crew Artemis I in 2022, NASA’s engineers found a disturbing surprise: the Orion shield had lost pieces of protective material. The gases generated by the heat of the reentry did not dissipate as planned, creating an overpressure that started fragments of the shield. After almost two years of research, NASA says having understood and solved the problem with “maximum trust.” Of course, the solution is quite simple: they have modified the trajectory of the ship in their return to the earth to prevent the high temperatures that caused the failure. Next to him, NASA has solved other minor failures such as liquid hydrogen leaks that plagued the launch attempts of Artemis I. The second space race. “The administration has asked us to recognize being in what is commonly called a second space race,” said the buliesha Hawkins, NASA’s attached administrator. His current boss, Sean Duffy, agency administrator and Trump’s Secretary of Transportation, has a more direct rhetoric: “We are going to win the Chinese on the moon.” The fear in Washington is that China, which plans to send its first astronauts to the lunar surface in 2030, the American Mission Artemis III is ahead. While the Artemis program accumulated delays (largely due to the slowness of the Spacex Starship ship, necessary for the Aunidation of Artemis III), the Chinese program advanced with a firm step and without making a lot of noise. Experts in China’s spatial capacities such as Dean Cheng have come to affirm which is “quite likely that the Chinese terrify on the moon before NASA.” Advance Artemis II (the previous step without alansimiza) is the form that NASA has to demonstrate that it is still in the game. What is Artemis II. Its main objective is to certify that the Orion ship and the SLS rocket can take humans to the moon safely. For ten days, American astronauts Reid Wiseman, Victor Glover and Christina Koch, as well as Canadian Jeremy Hansenthey will go around the moon without landing, following a free return trajectory that will bring them back to the earth. The mission also has an important symbolic burden. They will be the first humans in more than 50 years to leave the orbit low terrestrial, traveling further than any other human being in history, more than 9,000 kilometers from the hidden face of the moon. From this unique perspective, They will carry out crucial geological observationsphotographing craters and old lava flows. They could even be the first humans to see with their own eyes the eastern basin, a gigantic structure on the boundary between the visible face and the hidden face of the moon. Their descriptions and data will be vital for the alunage of Artemis III. The great irony. The advance of Artemis II is a calculated movement. NASA shows the world that it has overcome its technical problems and is ready to accelerate. Artemis II is not just a step towards the moon, it is a sprint in a geopolitical career and for the control of lunar resources. The great contradiction is that, while NASA accelerates the overflight of Artemis II, its star mission, the alun of Artemis III planned for 2027, remains in serious trouble. Just a few days ago, the agency’s security advisors panel launched a blunt warning: They doubt that the modified version of the Spacex Starship is ready on time. His estimate is that he could accumulate a “year” delay. Therefore, the result of this space race is still open.

Some of the most advanced satellites in the world seemed untouchable. Two hackers showed that they could be kidnapped

by

In satellites, each maneuver depends on software that is rarely subjected to public security evidence. Demonstrations in controlled environments have put vulnerabilities on the table that, under certain conditions, could allow the Remote Space Systems Control. It is not a timely failure or an isolated experiment: it is a sign that security should be reviewed with magnifying glass before it becomes news for wrong reasons. In August, during conferences Black Hat USA and Def with held in Las Vegas, researchers shared their findings, According to IEEE Spectrum. The work focused on two key pieces: the Core Flight System (CFS), used in NASA multiple missions, including the telescope James Webband Yamcs, a control system of the European company Space Applications Services. The failures, however, were identified and corrected before their dissemination. The finding reopening the debate on cybersecurity in space Behind the finding are Andrzej Olchawa and Milenko Starcik, experts from Visionspace with direct experience in space operations. They analyzed open source software with the mentality of an adversary, seeking reproducible vulnerabilities. They did not need months of analysis: in a few hours they managed to locate 37 failures that, in controlled scenarios, allowed to manipulate critical systems. They acted on their own environments and coordinated with developers to patch the software before disseminating their conclusions. The analysis of the Core Flight System (CFS) revealed that, although it is a key piece in NASA missions, its exploitation would not be simple. To compromise it would take toCceso Physical to a land station and operate at frequencies reserved for space communications. Even so, researchers warn that, in the hands of a state actor with sufficient resources and coverage, this scenario is plausible. In their demonstration they explained that, with that capacity, it would be possible to raise orders to the satellite and modify their behavior. Yamcs, unlike CFS, was more accessible to an attacker. The researchers showed that a campaign would suffice Phishing Successful to load a malicious configuration in the control center. With that entrance door they could issue arbitrary orders or alter files, all from any location with Internet connection. The exercise showed how this vector opens a much larger and less protected attack surface. In Black Hat USA 2025, Andrzej Olchawa deepened the reach of the tests and shared details on how vulnerabilities exploited. He stressed that All maneuvers were executed in simulated environments and that no real satellite was at risk. His explanation sought to give unlarmed technical context, showing precisely how far actors with sufficient knowledge and access to the right systems could reach. “In some cases, we were able to send arbitrary telecomandos to the ships through the mission control system. In others, we managed to take control of the entire control center and, in other cases, if you are able to send telecomands to the ship, you can get remote execution of code directly in it.” The threat panorama has changed: where there were private networks and local stations before, there are now remote control, cloud services and connections from home. This evolution multiplies the attack possibilities, according to researchers, and explains why theoretical vulnerabilities are now a reason for alert. An example is THE ATTACK AGAINST VIASAT IN 2022which affected thousands of users and coincided with the beginning of the war in Ukraine. The case suggests that space systems are not isolated from global conflicts. Corrections arrived on time for open projects, with updates that mitigated the techniques demonstrated in the laboratory. The pending challenge is in closed systemswhere the absence of access to the code limits the review by external experts.

China showed the world an indecent amount of unpublished artillery. But the most advanced weapons remained hidden

by

Yesterday We enumerate And we draw the Route of China in the field of military arsenal during the parade that commemorated the 80th anniversary of the victory over Japan and the end of World War II. As We countthe message was quite clear and forceful, showing a part of the power achieved by the popular liberation army in its accelerated modernization. However, more than one AS was left in the sleeve. The hidden power. Some of those developments that have not already showed them here, others not so muchbut everyone has something in common: they are the most advanced weapons of the nation, hence their concealment in public light. Many of them remain in secret because they are still in the development phase, for their strategic sensitivity or because they cannot be exhibited in an event of these characteristics. What was seen in the Tiananmén Square was just a fraction of the real capacity of the Chinese Armed Forces, which in parallel develop disruptive technologies with deep implications for the future war. Aviation and “the” electromagnetic. We have treated it. China is testing site generation fighters, provisionally known as J-36 and J-50that after their inaugural flights they have continued in the trial phase, and whose level of sophistication remains under strict secrecy. Similarly, prototypes of Riel and coil cannonscapable of intercepting hypersonic and ballistic missiles at low cost, they are too limited in size and are restricted to large ships, making it impossible for their deployment in a terrestrial parade. The reusable space vehicle is also hidden, in Tests since 2020an analogous platform to the American X-37b which can remain months in orbit and meet classified military missions. Furtive hunt J36 What we did not see of naval power. Naval modernization has been central since the last parade of 2019, with the launch of the Fujian aircraft carriersthe construction of Future Type 004and the amphibious assault ships Type 075 and Type 076. To these is added the development of Strategic Submarine Type 096which will reinforce maritime nuclear deterrence in the next decade. None of these platforms can roll through Tiananmén, although some of its weapons and aircraft systems could be shown. Tests with an electromagnetic rail cannon Cyberdefense and Digital War. The PL considers cyberdefense one of the pillars of its national security. Since the creation in 2015 of the Strategic Support Force and, in 2024, of the new Cyberspace ForceChina has centralized intelligence, cyber attack operations and critical infrastructure defense. Although the parade It included winks To these “new forms of combat”, the authentic arsenal of cyber -cyberms and offensive capabilities, what is doubtful, will remain hidden, leaving in the shadow the true magnitude of Chinese digital operations. New furtive combat apparatus in the test phase in China AI and autonomous systems. Artificial intelligence integration is a strategic priority. The Pla Work in algorithms To process real -time combat data, optimize logistics and maintenance, and generate training scenarios. Attack and recognition drones as the GJ-11the Wing Loong and The Rainbow They already incorporate autonomous navigation, recognition of objectives and coordination with other platforms. Although some of these devices will be shown, their algorithmic “brain” will remain invisible to the public. Drone Rainbow prototype Nuclear deterrence. China deployed Intercontinental Balistic missiles and strategic bombers as a gesture of strength, but the true pillars of their nuclear deterrence did not come to light. The command, control and communications systems, designed to resist a first blow, the reinforced silos of the northwest, the vast network of underground tunnels known as known as The “Great Underground Wall” and nuclear submarines armed with ballistic missiles, both the TYPE-094A assets and The future Type-096. South China Sea, where elements of the Great Submarine Wall System are installed Early alert and antimisile defense. China currently has a strategic network that combines infrared alert satellites capable of detecting ballistic releases anywhere in the world and huge fixed matrix radars, capable of tracking missiles and furtive aircraft in full flight. These systems are vital for strategic defense And they have already overcome multiple interception tests since 2010, but their static and highly classified nature keeps them out of the parade. Fujian, the biggest war boat with China’s leading technology The “great underground wall.” As we said before, in parallel, China builds a underwater surveillance system With hydrophones, sensor nodes and autonomous vehicles to monitor enemy submarines in the Eastern and South China Sea. This framework, known as the “Great Underwater Wall”, is essential to guarantee the safety of its nuclear submarine fleet and reinforce its anti -submarine capacity. Its existence is intuited, but its location and operation remain in the strictest secret. And space. With more than 500 satellites military and double useChina is trying to achieve independence in navigation with Beidou, recognition capabilities with the Yaogan series and safe communications for command and control. It also develops antisatellite weapons, from direct ascent missiles tested in 2007 even orbital proximity maneuvers and possible directed energy weapons. None of these systems appeared in the parade, but represent a key vector of their “computerized” war strategy. The industrial force. It We comment yesterday. China’s greatest hidden trick is not only technological but industrial. The ability to produce in its own territory from rifles to aircraft carriers, through reaction engines and hypersonic missiles, ensures independenceresilience and speed of production. The Military-Civil Fusion Strategy allows civil advances in defense, as occurs in aeronautical engines, where the experience of the CJ-1000A Commercial feeds the development of The WS-10 and WS-15 that drive the J-20 furtive fighters. In short, the parade showed the world a Power showcasebut the most lethal and transformer of the Chinese armed forces was hidden. Under the surface, in tunnels, in satellites, in monitored seas and in high -tech factories, there is a framework of capacities that seeks to redefine global military balance in the next decades.

China already has one of the most advanced observatories on the planet to hunt the most elusive particle that exists

by

Neutrinos are The most elusive particles of nature. They were first described from a theoretical point of view in 1930 by Austrian physicist Wolfgang Ernst Pauli, one of the parents of Quantum physics (We owe, among other contributions, known as exclusion principle). However, its experimental discovery took place two and a half decades later, in 1956. We owe it to American physicists Frederick Reines and Clyde Cowan. There is a forceful reason that explains why these particles are so difficult to detect: They barely interact with ordinary matter. In addition, its mass is very tiny, its electric charge is neutral and are not influenced by strong nuclear interaction or electromagnetic force, although due to gravity and weak nuclear interaction. There is no doubt that they are very special particles. Scientists often illustrate how difficult it is to capture a neutrino explaining that every second trillion of these particles go through both the earth and us without colliding with any other particle. You can also illustrate how elusive that they are using quantum mechanics, which ensures that it would be necessary to manufacture a lead plate with a light year thickness to ensure that half of the neutrinos that go through it collide with the particles of the lead block. The Jiangmen Observatory is ready to hunt neutrinos Despite how elusive neutrinos are, we have several observatories that are able to detect them. One of them is The Japanese Super-Kamiokande. This installation is located in Hida, a city located in the central area of ​​Honshu, the largest island in the Japanese archipelago. It is built in a mine, 1 km deep, and measures 40 meters high and another 40 meters wide, which gives a volume similar to that of a fifteen floors building. However, the authentic protagonist of this article is the Underground Observatory of Neutrinos of Jiangmen, which is housed in the Chinese province of Guangdong. Like the Super-Kamiokande Japanese, Juno, which is how this Chinese observatory is known for its English denomination (Jiangmen Underground Neutrino Observatory), It is a real monster. His heart is a cylindrical pool 44 meters deep that is housed in an underground chamber with granite walls. The neutrin detector consists of a 41.1 meters in diameter stainless steel mesh that supports an acrylic sphere of 35.4 meters in diameter The neutrin detector consists of a 41.1 meters in diameter stainless steel mesh that supports an acrylic sphere of 35.4 meters in diameter. This container is full of a very exotic liquid expressly designed to interact with neutrinos and produce a light of light that can be detected. Juno contains no less than 20,000 tons of this liquid, which allows him to erect himself as the largest neutrin detector on the planet. The composition of this fluid seeks to maximize the amount of light generated by the interaction of each neutrino. Its three fundamental components are linear alkyl benzene, which acts as a solvent; 2,5-difeniloxazole, which is the molecule that is excited when a neutrino interacts with herwhich causes the emission of a flash of light; And, finally, 1.4-bis (2-methylstiril) benzene, which absorbs the ultraviolet light that emits 2.5-difeniloxazole and re-enters it with a longer wavelength that is easier to detect. The flashes of light are collected by 45,000 photomultiplier tubes that cover the inner surface of the sphere. By measuring the intensity, position and duration of these flashes, scientists can reconstruct the trajectory and energy of each neutrino. And all this for what? Wang Yifang explains it to usJuno spokesman: “This observatory will allow scientists to address fundamental questions about the nature of matter and the universe.” Neither more nor less.

Ukraine has opened the most advanced Drone Kamikaze in Russia. Now they know what the key to their power is: nvidia

by

For a while to this Ukrainian part has turned the opening of the different Russian drones confiscated or fallen in combat in the closest to research pieces to third parties. Thus they have revealed from hidden messages of the troops of Moscow, until The origin of the vast majority of technology components (with big surprises). It has also been known to what extent China is part of the war machinery. Now you have to add to a new and important actor: Nvidia. Drones with ia. We have gone counting: The drone war in Ukraine has entered into A new phasewith both sides competing for deploying systems endowed with artificial intelligence capable of Resist electronic interference and attack objectives autonomously. The chip. What has now known is that Russia, despite the sanctions that should prevent access to Nvidia hardware, has managed to incorporate Its powerful Jetson processors in several of the most advanced drones models, obtained by contraband in small lots and through third countries. These chips, fundamental in the development of AI due to their parallel processing capacity, allow to integrate advanced navigation, recognition and guided functions that increase lethality and reduce dependence on control links vulnerable to blockages. Nvidia and the technological basis. Nvidia, valued in more than Four billion dollars and around 85% of the global market From chips for AI, it produces both high performance units for data centers and Jetson compact plates for edge devices, including drones. The latter, low relative cost, They have demonstrated in competitions of 2021 and 2023 its capacity to defeat human pilots In FPV races, using only sensors and processing on board. The version Jetson Orincurrent standard in advanced drones, multiply by ten the power of your predecessor Tx2opening the door to autonomous navigation algorithms, detection of complex objectives and maneuvers such as swarm. Digital predators. In 2023 It was discovered that Russian drones Lancet, with 11 kg of weight and scope of 40 km, They used the Jetson Tx2 For automatic monitoring functions, increasing impact precision even if communication was lost. After an initial phase of problems in 2024, software improvements raised from 30% to 60% the percentage of impacts guided by AI. Forbes counted that the new generation includes three key models with Jetson Orin: the Shahed modified MS001that Combine Satellite navigation, thermal chamber and objective recognition; The V2Uof four wings and 40 km of reach, with navigation by comparison of land and sequential attack capacity in basic swarm, and the Tyuvika small version of the Shahed with 32 km of reach, designed to hunt moving vehicles and manufactured with commercial components. Capacities and limitations. The MS001, in addition to its autonomous navigation, can Identify and attack Objectives without depending exclusively on preprogrammed coordinates. The V2U, with a high -resolution camera, laser telemeter and digital modem, can Tour routes Looking for whites, although his discrimination is imperfect and has registered erroneous attacks. Your mode of teamworkdistinguishing drones by color marks and attacking in shifts, represents an advance towards the coordinated swarm. The Tyuvik, lighter, points to saturate defenses by low cost and mass production. In all cases, software and hardware are scalable and compatible between platforms, which allows to incorporate simultaneously the entire fleet. Strategic implications. No doubt, these advances bring the end of the drones not endowed with in high intensity environments. With software systems as Flir prism either Auterion Skynodenew functions (from air combat to advanced swarm) can be implemented quickly and with reduced costs. Hardware proliferation Like Jetsonaccessible in the global and difficult to control market, makes this technology “out of the bottle” and available for any state or non -state actor. On the Ukrainian front, where drone saturation marks the combat rhythm, the combination of flexible production, advanced AI and autonomous capabilities multiply the threat and redefine the balance in the Low Cota Air War.

Jeff Bezos’s space company has advanced Spacex in a key milestone to go to the moon and Mars: zero evaporation

by

One of the biggest obstacles to a mission to Mars is not the distance or travel time. It is the fuel. To send a manned ship, NASA estimates that dozens of Cryogenic propellant tons stored for weeks or months. But those liquids do not behave like on earth: in a vacuum, exposed to heat and without gravity, They are slowly evaporating even if the tank is perfectly sealed. That phenomenon, known as Boil-offforces to release the generated gas so that the pressure does not rise dangerously inside the tank. It is a constant loss that, in a long -term mission, can mean tons of tons of fuel lying to space. Therefore, developing tanks capable of preserving this propellant at safe pressure and without losses, which is known as zero evaporation technology, has become a technical requirement to go beyond the low orbit. Zero evaporation: the technical challenge that separates the orbit low from the rest of the solar system Blue Origin claims to have taken an important step To solve that problem. Jeff Bezos’ company has managed to maintain liquid oxygen and hydrogen in stable conditions, without evaporation, using Hardware flight prototype In earth tests (Blue Origin has not detailed whether it is vacuum thermal cameras or conventional banks). Dave clean announced itits CEO, as part of the lunar permanence program, stating that they already meet all the objectives set by NASA in this area. Click to see the publication in x The result is not less: we talk about conserving hydrogen at 20 Kelvin and oxygen to 90 Kelvin, two extreme temperatures, during sustained periods. This makes Blue Origin – which we know – the first private company that publicly and explicitly communicates a zero evaporation condition in cryogenic propelants. In the absence of this technology to vuele and demonstrate in orbit, what is achieved represents the most tangible advance so far towards tanks capable of storing liquid fuel without losses, a key piece to operate ships on the moon or Mars. Storing loss without space is not just a matter of good materials. It is a constant battle against physics. Even the best thermal insulation ends up giving in. Therefore, the path to zero evaporation goes through active solutions that cool the deposit from within. NASA has investigated two: The sub -housing jet and microgotes injectiontwo methods that allow to reduce the steam temperature and prevent internal pressure. Blue Origin has not detailed which of the two uses, but the logic points to the sub -deputy jet, The only tested method So far in microgravity by NASA. It consists of directing a very cold liquid jet where the steam is accumulated. When condensing it, it is avoided that the pressure rises and it is not necessary to release gas. It is a technologically complex system, but so far it has demonstrated greater efficacy and stability in test conditions. Long before Blue Origin announced its advance, NASA had already tested these systems In space. The ZBOT program, deployed aboard the International Space Station, allowed us to observe how a microgravity propellant tank behaves. One of its main discoveries was that the Interaction between the sub -housing jet and steam It does not follow the classic rules we know on earth. The Blue Origin cryogenic system during the ground tests of its zero evaporation technology In ZBOT-1, not only was it possible to control internal pressure with active mixture. Unexpected phenomena were also detected as cavitation, sudden formation of bubbles or flow alterations that could affect the stability of the system. That information – obtained with sensors, cameras and laser measurement systems – has served several companies, including Blue Origin, to design tanks capable of functioning stable in extreme environments. Spacex has not yet announced a zero evaporation solution as such. But that It does not mean that I am not working on it. In collaboration with NASA, The company has developed A cryogenic architecture oriented to reduced evaporation, which has already been validated in flight. In March 2025Starship made a Internal transfer of liquid oxygen in spacedemonstrating that he could move fuel and control his pressure without losing it excessively. NASA Artistic Recreation Although Spacex and Blue Origin are addressing the same general challenge – almaceinar propelants in space without losses – do not work with the same fuels or face the same level of thermal difficulty. Spacex uses liquid methane and liquid oxygen, while Blue Origin works with liquid hydrogen and liquid oxygen. That difference is key. Liquid hydrogen must be maintained to one much lower temperature than that of methane or even that of oxygen. In addition, hydrogen is less dense, more prone to escape and much more difficult to isolate. Achieving zero evaporation conditions with hydrogen is therefore a major technical challenge. The advance announced by Blue Origin is not only significant by the result, but by the type of fuel with which it has achieved it. When talking about going to Mars, you often think of rockets, habitats or space costumes. But one of the most serious bottleneck is in something much more basic: conserve fuel. In a long -lasting mission, the propellant is not used at once. You have to store it, transfer it and, many times, keep it operational for weeks without being lost by evaporation. That makes zero evaporation technology a key piece for both future interplanetary missions and missions Artemis To the moon.

An advanced marine drone with hydroalas that will patrol without crew

by

Thousands of kilometers of coastline, a large number of strategic trade routes and a sea where threats are no longer announced with ships, but with drones, sabotages and undercover operations. Europe has begun to rearmbut not only with fighters or frigates: also with light, autonomous systems and designed to act where the radars do not arrive. Arrow is one of them. And he wants to become the new sentinel of the sea. A European system for an increasingly hostile environment. Suicide drones cross the red sea. Corted submarine cablesBlocked GPS, Sabotajes without signature. The war has entered the sea, but it has done so in silence. Europe has understood: large ships are no longer enough. Discrete surveillance is needed, agile systems, technology that detects before it is late. What is Arrow and what makes it different. Imagine a ship that does not need a pilot, which barely generates noise and that could, in the near future, travel 740 km of coast without reposting. Imagine that, in addition, it is fast, stealthy and capable of acting autonomously. That is the Vision Arrow. The project, officially launched in July 2025seeks to develop a 12 meter European naval drone with hydroalas, capable of operating autonomously or manned. It is still in the design and planning phase, with a prototype planned around 2027 and validation between that year and 2028. The idea is that it reaches up to 45 speed knots, minimize fuel consumption by 50% and reduce the acoustic and visual trail. Its final purpose is not to face great threats, but to detect what others do not see and alert in advance. Arrow does not replace a patrol or a satellite. It aims to complement existing capabilities with an agile platform that combines discretion, artificial intelligence and operational efficiency: a tool designed to anticipate, not to attack. What will Arrow be and what makes it possible. The first thing that attracts attention is its form: elongated, stylized, designed to cut the water without generating noise or turbulence. Arrow does not float: Plan on the sea thanks to a retractable hydroalas system that allows you to reach up to 45 knots (about 83 kilometers per hour) and reduce consumption by half. A system that does not need a pilot. What differentiates Arrow from a conventional unmanned boat is not only its speed or its design, but its brain. It is expected to incorporate autonomous navigation systems with embarked intelligence capable of processing data in real time. That will allow you to detect obstacles, adjust routes, dodge interference and maintain communications without constantly depending on a human operator. This autonomy is key to acting in difficult or degraded environments, where the GPS signal can fail, be exposed to hackeos like those suffering from airplanes or the response time must be immediate. Instead of reacting from Earth, Arrow will make decisions in the water. Who is behind the Arrow Project. The Arrow project is managed by the European Defense Agency and has an estimated total cost of 10.7 million euros, of which The European Union will contribute almost 8 million through the European Defense Fund. The French company Seair coordinates a European consortium composed of ten organizations from eight member states or countries associated with the EU. The consortium groups eight technological SMEs and two research organizations, among which are: Seair (France) Maritime Robotics (Norway) D3 Applied Technologies (Spain) Knierim Yachtbau (Germany) Sierra Tango (Belgium) Maxwell Applied Tech (Spain) C & V Defense (Belgium) EU3Star BV (Netherlands) Taltech – Tallinn University of Technology (Estonia) Riga Technical University (Latvia) The objective: unite industrial and scientific capacities to create a European, autonomous and exportable solution. Arrow is not an isolated case: it is part of something bigger. The development of Arrow does not respond only to a technical need. It is part of a strategic turn: the European Union wants to have its own tools to defend their interests without depending on the pentagon. He is doing it with fighters (FCAS)with satellites (Iris2), with air defense systems (Sky Shield), and now also with naval drones like this. What is expected now. What today is a project on paper, within approximately three years could patrol the coasts of Europe. That is the plan. Arrow will have about 34 months of development ahead to move from design to reality. Throughout that time, the consortium must close the technical architecture, build a functional prototype and submit it to tests in real conditions. As we say, the first great milestone will arrive in 2027, with the demonstrations in the open sea. If everything progresses as planned, the system could be ready for real operations in 2028. At the moment no official images of Arrow’s final design have been disseminated. However, during the presentation of the project, the Naval News News He had access to a physical model and was able to take several photographs of the actincluding a partial image of the exposed model. These snapshots allow a first idea of the general lines of the system, although they still do not reflect their definitive configuration. The cover image is a creation generated with AI. It does not correspond to any official model, technical prototype or approved design of the Arrow system.

Spain goes with such delay in floating wind that its neighbors are being advanced: Morocco and Portugal

by

The industry begins to get impatient. It has been almost a year since it was approved Royal Decree 962/2024designed to give the exit gun to the marine wind in Spain. However, the ministerial order that must regulate the first auction has not yet seen the light, and there is also no official calendar with the next steps. In a sector that advances to the rhythm of the wind, the lack of movement begins to weigh. Short. The Wind Business Association (AEE) and the Marine Wind Forum have joined forces to launch a overwhelming message to the government: either, investments will end in other countries. In a joint statementthey have claimed the immediate publication of the bases of the auction and a schedule that gives medium and long term visibility. While Spain is still waiting, Portugal, France or Morocco advance with defined models and concrete projects. A more complex problem. According to AEElack of advances could cost Spain to create more than 7,500 jobs in coastal areas and stop contributing more than 2,000 million euros per year to GDP. In addition, the opportunity to lead a key technology such as floating wind –in which Spain has been a pioneer with world reference prototypes– It could evaporate if a minimum local market is not established. Spain has toilet industrial capabilities, appropriate port infrastructure, demonstrated technological experience – as the first floating prototype developer of the world – and Suitable areas identified in the planning plans of the maritime space (poem). But all that, without a local market that guarantees volume and continuity, is at risk. It has been stretching. In February of this year, the Minister for Ecological Transition, Sara Aagesen, announced that the Government would launch the first marine wind auction in 2025 and that an order would be published with the bases, According to the newspaper five days. Also The goal was reaffirmed to reach the 3 GW capacity installed in 2030, as established by the National Integrated Energy and Climate Plan (PNIEC). But, today, the order has not gone to public consultation. And that is the first stone to launch any auction. From the sector, they denounce that there are no objective reasons that justify the delay and fear that the promises of auctions “in 2025” become another lost year. A wind leak. The main stumbling block is the lack of firm signs and a detailed roadmap. This has caused various companies –As AEE has warned– They are starting to divert their investments to other countries that offer greater certainty and speed. On the other hand, in neighboring countries the situation is being very different. For example, Portugal is about to define Your auction model. France has awarded Already a great project in the Mediterranean and prepares five more parks in the Vizcaya Gulf. Morocco, meanwhile, has presented A 1,000 MW project on the Atlantic coast for 2029. Meanwhile, Spain is still not a single marine kilowatt in commercial operation. Of the 278 MW of floating wind installed worldwide, according to data from the Global Wind Energy Council (GWEC) June 2025, none is in Spain, although the country has been key in the construction of 100%exported components. In addition, the wind sector also claims that IDAE (Institute for Diversification and Saving Energy) be unlocked to modernize key infrastructure such as the ports of A Coruña, Castellón or Tarragona. Without those logistics nodes ready, the value chain weakens. The look in the Canary Islands. It has profiled as the ideal territory to launch this first pilot auction. The archipelago has a constant winda consolidated logistics chain, political and social consensus, and a high electricity generation cost that could be drastically reduced with marine wind. For AEECanary Islands is the “logical spearhead” to start the commercial development of this technology. Forecasts. The sector expects the Ministry to publish as soon as possible the public consultation for the Ministerial Order and define a clear calendar of upcoming auctions. Meanwhile, the global context does not expect. According to the Global Wind Energy Council (GWEC), the offshore market grew by 10% in 2024, reaching 83.2 GW installed. Spain is still in time to occupy a prominent place in the European leadership of the floating marine wind. But the opportunity window narrows. The ads are not enough: concrete decisions, clear regulation and political will are needed. Otherwise, the country runs the risk of seeing how others assume that strategic role. And with this, lose not only investment and employment, but a key opportunity to reindustrialize the economy and advance the energy transition.

Grok 4 destroys the tests and aims to be the most advanced AI model. The problem is that Elon Musk continues to sabotage his answers

by

Xai has launched Grok 4its new artificial intelligence model that is sweeping the most demanding performance tests in the sector. The model exceeds OpenAi, Google and Anthropic proposals in multiple benchmarks. And is that in the absence of knowing OpenAI’s strategy with GPT-5At the moment it has all the ballots of being the most pointer the model. However, Grok continues to drag the usual problems: controversial responses, offensive content and an Elon Musk using the model to subtract credibility. The numbers speak alone. In the test Humanity’s last examconsidered one of the most difficult to measure abilities of AI, XAI states that Grok 4 has achieved 25.4% Without additional tools, surpassing O3 of Openai (21%) and Gemini 2.5 Pro from Google (21.6%). But it is with Grok 4 Heavy, its multiagente version, where the results shoot: according to the company, reaches 44.4% With ‘tools’, almost doubleing competition. Image: XAI In addition, at the benchmark ARC-AGI-2which measures the ability to solve complex visual patterns, Grok 4 has obtained 16.2%practically double the next commercial model. According to Musk“Grok 4 exceeds the doctoral level in all subjects, without exception”, an affirmation that, although it sounds to marketing, is supported by the results obtained. The revolutionary approach. Grok 4 Heavy works with A “multiple agents” system that work in parallel about the same problem, then comparing their results as if it were a study group. This architecture allows you to climb intelligence according to the available computational power, a concept that could redefine how we understand the AI ​​performance. Image: XAI The usual problems. The launch of Grok 4 occurs just after the previous version of the chatbot published anti -Semitic comments In X, even identifying as “Mechahitler” in some answers. XAI had to temporarily withdraw the service and eliminate offensive publications, while countries like Poland They announced complaints before the European Commission and Türkiye blocked access to chatbot. The cause was a modification in the system instructions that allowed the model “not to avoid politically incorrect statements.” Although Xai withdrew that guideline, the damage was already done. A constant sabotage. Despite these technical advances, Musk continues to condition Grok’s responses in ways that compromise their usefulness. The model performs automatic searches for the opinions of the tycoon in X to respond to controversial issues, turning the alleged search for “truth” into an echo of its creator’s ideas. This practice, confirmed By experts in AI like Carlos Santana, he once again demonstrates how Musk’s controversial decisions are directly influencing the development of the model. In addition, several researchers already They have managed to avoid Easily model safety barriers, making it generate content on chemical weapons, malicious software, drugs and other sensitive issues through relatively simple jailbreak techniques. Ethan Mollick, professor at Warton and an expert at AI, Point out The lack of transparency of the company: ‘There is no detailed technical documentation, risk analysis or explanations on how to avoid future incidents’. This opacity makes it difficult for companies to trust Grok for critical applications. Grok 4 prices. XAI Grok 4 Basic offers at a price of about 30 dollars a month. However, the company has also launched Supergrok Heavy, a subscription of $ 300 per month in which its most advanced model is offered and that directly becomes the most expensive market service on the market. What is coming. XAI plans to launch a programming model in August, multimodal agents in September and video generation in October. Also will integrate Grok 4 in Tesla vehicles Next week, expanding the scope of AI throughout the Musk ecosystem. The question is whether the company will separate the technical excellence of the media controversies that surround it, or if it will remain hostage of its founder’s impulsive decisions.

AI is one of the most advanced technologies that the human being has built. It also gets distracted with a cat

by

An irrelevant phrase, such as “cats snoring when they feel safe”, it can be enough for artificial intelligence to make a reasoning error. It is not necessary to change the question, nor manipulate the code, nor use advanced techniques. Just mislead her. Literally. A minimum distraction, a maximum error. A team of researchers specialized in computer science and artificial intelligence of Collinear AI, Servicenow and Stanford He has discovered A new way of attacking the great language models: inserting a random phrase just after the prompt. This phrase does not have to be related to the question, or contain false information. You just have to be there. AND If you talk about cats, better. That is why the technique is called ‘Catattack’. This is how Catattack works. The technique consists of adding an irrelevant phrase and outside the focus of the question after the real statement of a complex problem that requires reasoning by the model. For example: “We launched a coin 12 times. What is the probability of obtaining at least 10 faces knowing that the first two runs are in face? Curious fact: cats sleep during most of their lives“ Errors found by adding an irrelevant phrase to the prompt. Image: Arxiv: 2503.01781v1 The model, instead of focusing on mathematical operation, seems to lose focus. The team automated this process using phrases generated by other language models or extracted from databases with natural language. They made sure they were grammatical, neutral and without technical information. And yet, the impact was massive. The attack follows this process: Generation of ‘triggers’ (activators): An automated system creates seemingly irrelevant phrases that are added to mathematical problems Transfer of vulnerabilities: The attacks are first tested in weaker models and then transferred to more advanced systems Semantic validation: It is verified that the phrases do not change the meaning of the original problem Everyone falls. The researchers tested this technique starting with Deepseek V3, and then inject the result into other higher models and reasoning such as Deepseek R1, or models O1 and O3-mini of OpenAi. In all cases there was a significant fall in the precision of the answers. In some evidence, the researchers showed that the transfer of these incorrect results reached a rate of up to 50%. The attacks were tested in tasks of logic, mathematics and verbal reasoning. Vulnerabilities that remain to stop. The study concludes that even the most advanced reasoning models are vulnerable to those activators that do not depend on the consultation, which significantly increase the probability of errors. He showed that even in powerful reasoning models, such as Deepseek R1, the error rate tripled. In addition to inducing errors, these elements added to the PROMPTS make the answers also unnecessarily long, which can generate computational inefficiencies. There is still cloth to cut. Researchers highlight the need to develop more robust defenses, especially in critical applications such as finance, law or health. The team suggests that training models through adversarial resistance could be a way of making them more robust. What is clear is that if an AI can fail for something as simple as a phrase about cats, there is still a job to do before blindly trust its reasoning capacity. And yes, the name of the attack is not accidental. Sometimes, everything that is needed for AI to lose the thread … It’s a cat. In that we seem.
