Data centers in space promise to save the planet. And also ruin the earth’s orbit

by

Wikipedia should update its page dedicated to the word “ambition” to include Elon Musk’s photo. The tycoon has announced a megaproject according to which his two companies SpaceX and xAI will work together to launch a constellation of one million satellites that will function as data centers in orbit. The problem is that although the idea It has its advantages, it also has an impact potentially terrible for the future of our planet. Energy efficiency. That is the great advantage of the space data centers that Musk proposes. In space, solar panels can perform optimally without the obstacles posed by Earth’s atmosphere and climate. According to SpaceX, the reduction in the cost of launching its rockets makes space a perfect alternative for AI data centers. The plan. He project that has been presented to the US Federal Communications Commission (FCC) consists of placing these satellites in sun-synchronous orbits between 500 and 2,000 km high. That would allow the satellites to act as interconnected nodes among themselves and also with the satellites of the Starlink network through optical laser links. The plan, of course, will have to overcome important challenges like refrigeration. Dissipating the heat generated by millions of chips in the vacuum of space is complex, since satellites act as “natural thermoses.” And radiation, what? The problem of cosmic radiation will also have to be solved. Advanced chips are very vulnerable to processing errors caused by energetic particles. It seems that AI processors are surprisingly resistant to this type of problembut the deployment of such chips on a massive scale in space could introduce new conflicts. On-site repair, nothing. In today’s data centers, if a problem arises, a technician can physically travel if necessary to solve it. In space, physical repair is not feasible, which would force a strategy of assuming that those chips that become functionally damaged will be completely lost. SpaceX would have to continuously launch substitutes to compensate for this “mortality” of components, which complicates logistics and costs. There are optimistic perspectives in this regard, and for some the bills do work out. Kessler syndrome. But above all there is a latent concern in the field of space security. Launching a million new satellites into already congested orbits multiplies the probability of chain collisions, validating the theory proposal in Kessler syndrome. A single major collision could generate a cloud of debris that would take decades to clear, further threatening climate monitoring missions or even global communications. There are already ideas to “regulate orbital traffic” by coordinating it, and SpaceX has its own “situational awareness” system, Stargazeto avoid problems, but of course, no system is completely perfect. air pollution. Without forgetting that the atmospheric impact is equally worrying. Some are estimated 25,000 Starship flightsand the re-entry of satellites that end their life cycle or die prematurely would cause metals and particles to be released into the upper atmosphere. According to experts, these chemical residues could damage the ozone layer and cause uncertain climate consequences. You can’t see anything. The astronomers, who They had already protested about Starlinkthey will have an even bigger problem with this new idea. The threat to astronomy is clear, because given the altitude and size of these satellites, it is likely that they form a bright band visible even to the naked eye, making scientific observation difficult and even changing the way we see the sunset. Orbital computing may have advantages, but before launching it we should remember that space—especially the space we see—is a shared and finite resource.

The scientist who made the AI ​​we know today possible has just raised 1 billion. His new goal is to teach him to see space

by

Fei-Fei Li, known as the godmother of AIjust closed a $1 billion round for World Labs, his startup dedicated to teaching machines to understand the world in three dimensions. Behind this bet are large companies such as NVIDIA, AMD, Autodesk or the Andreessen Horowitz fund, among others. Li, like other important figures in the field of AI, believes that world models are the way to go, instead of the AGI. Who you are and why what you do matters. Li is one of the people who made it possible for the Generative AI as we know it today existed. He was part of the team that developed ImageNet, a database of millions of images that allowed computers to learn to recognize objects in photos. That academic work was the trigger for the leap towards deep learning that gave rise to everything that came after: from voice assistants to generative models of text and images. Now, from Stanford University, where he directs the Institute for Human-Centered Artificial Intelligence, and from World Labs, the startup he founded in 2024, Li points to what he considers the next big unsolved problem in AI: that machines understand the physical world, not just text or flat images. The problem you want to solve. The great language models like GPT either Claude They are extraordinarily good at processing text. But the real world is not text, or at least it is not only text: it is three-dimensional, it has physics, it has geometry, it has objects that move and relate to each other. “If AI is to be truly useful, it must understand worlds, not just words,” counted Li in his statement. That is what so-called spatial intelligence, the central focus of World Labs, pursues. Unlike working with two-dimensional data, the models the startup works on are designed to perceive, generate and interact with three-dimensional environments. The idea is that an AI with spatial intelligence can reason about how things work in space, where an object is, how it moves, what will happen if it is pushed, how it fits into a larger environment, etc. What already exists and what is coming. In November of last year released Marbleits first commercial product. It is a model that generates editable and downloadable 3D environments from text, images, videos or panoramas. The user can create a virtual world, modify it, expand it and export it in different formats. The startup positions it mainly for video games, visual effects and virtual reality, or sectors with a huge demand for 3D content in which there are few tools to put them into operation. With this new round of financing, the focus also expands to robotics. And in this field, spatial intelligence is especially critical, since a robot that understands the space around it can plan actions before executing them, process different ways of completing a task or adapt to changing environments without needing to be reprogrammed for each situation. Autodesk has put 200 million at your table. It really makes perfect sense. It is the company that makes the design software used by architects, engineers, animation studios and manufacturers around the world. Your business is, by definition, thinking in three dimensions. And if Li’s models can generate and reason about 3D environments, Autodesk tools can also benefit from what the startup aims to offer. Daron Green, chief scientist at Autodesk, explained to TechCrunch that the collaboration between both companies will initially focus on entertainment and audiovisual production. The idea is that design workflows can be combined with AI-generated worlds. In this way, a user designs an object in Autodesk and places it in an environment created by World Labs, or the other way around. “You might anticipate that we will consume their models or that they will consume ours in different contexts,” Green said. You are not alone in this race. World Labs is not the only commitment to world models. Google DeepMind works on your family of Genie modelscapable of generating and simulating 3D environments. Yann LeCun, who was chief AI scientist at Meta, just founded AMI Labs with the same approach. Startups like Decart and Odyssey They also move in this spacealthough with products still in the demo or research phase. However, there are differences in their respective approaches. LeCun, for example, defends that to build true world models a completely new AI architecture will be needednot generative. Li, from World Labs, is committed to advancing with current generative models and improving from there.

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

by

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

China’s nuclear renaissance is now visible from space

by

Since China detonated its first atomic bomb In the midst of the Cold War, its relationship with nuclear matters has been marked by secrecy, declared prudence and a deep distrust of the great powers. For decades it chose to stay in the background, building capabilities away from the spotlight and speaking little about them. This historical silence is key to understanding why, each time that something moves In that area, the world pays attention. A silent resurgence in the mountains. The story was brought in a special the new york times this weekend through satellite images. In the humid and rugged valleys of Sichuan, far from prying eyes, China is reactivating and expanding a nuclear infrastructure conceived for another era but adapted to a rivalry between superpowers that is intensifying again after the end of the historic pact between Moscow and Washington that we counted recently. Images from space show new bunkers, ramps and industrial complexes with ventilation and thermal dissipation systems that aim to high risk activitiesintegrated into a framework that no longer seems defensive or residual, but rather coherent with an accelerated and planned expansion that has been gaining pace since the end of the last decade. The inheritance of the “Third Line” and its update. These enclaves are not born from nothing, but sink their roots in what was called lto “Third Line”promoted by Mao Zedong to protect the nuclear heart of the country from American or Soviet attacks. For decades, that internal nuclear empire remained in the backgroundreduced and fragmented when global tensions eased. Today, those same facilities seem regain prominencenot as relics, but as modernized nodes that recover their central function in a China that has left behind the doctrine of minimum containment. Zitong in 2022 (top) and 2026 (bottom) Zitong and Pingtong: key pieces. They explained in the Times that the work detected in Zitong suggests advanced testing of high-precision explosives, essential to perfect the implosion that initiates a nuclear reaction, while the Pingtong complex, with its large ventilation chimney and its characteristic architecture, points to the manufacture of metal cores of the warheads, probably plutonium. The structural similarity with foreign facilities specialized in this process, like Los Alamos National Laboratory, reinforces the idea that China is closing the full cycle of design, testing and production of modern nuclear weapons. Intelligence, data and the value of what is not seen. Beyond the visible, the real leap is in the integration of intelligence, geospatial analysis and advanced simulation capabilities. The great laser ignition laboratory in Mianyang allows the behavior of nuclear warheads to be studied without the need for actual detonations, an approach that reduces political and environmental risks while accelerating technical refinement. In this way, each work detected is only a fragment, but together they form a mosaic that reveals a strategy based on accumulating knowledge, validating designs and gaining operational confidence without openly crossing international red lines. A direct challenge to gun control. There has been a lot of talk about these in recent weeks with the end of the New Start treaty. This Chinese acceleration would complicate any attempt to revive global nuclear control agreements after the expiration of that last treaty between the United States and Russia. Washington insists that China must form part of any new framework, but Beijing avoids commitments that limit growth that it considers necessary for its status as a global power. The American accusations of covert tests, rejected by China, add a layer of mistrust that pushes both sides to plan based on worst-case scenarios. Taiwan and the logic of enhanced deterrence. The backdrop to this effort is China’s perception of vulnerability to nuclear coercion American, especially in a plausible crisis over Taiwan. As? A largest arsenaldiverse and technologically tuned offers Beijing the feeling of sufficient immunity to maneuver more freely in a conventional conflictraising calculation risks for all parties. In that sense, what is happening under the mountains of Sichuan is not only an industrial modernization, but rather points more to a strategic bet that redefines the balance and forces the rest of the world to interpret, and the “intimate enemies” to react, if They are not doing it anymore.

China needed space to power millions of homes, so it built a mega solar plant in the open sea

by

That China is building power plants As if there were no secret, it is not a secret. Without going any further, in the last four years it has been able to replicate the power of the United States, the largest electrical grid in the West. And a good part of the blame solar energy has it. In fact, in 2023 it installed more solar panels than the United States in all of history, as reported by Bloomberg. Solar energy requires space, so China is finding the most varied gaps, from the tibetan plateau to the open sea, where from the end of 2025 It is already connected to the electrical network a mega solar plant that breaks records. In China there are solar panels even in the soup. The largest offshore solar plant in the world. We are talking about the solar plant located off the coast of Kenli district in Dongying city, Shandong province. This engineering project is carried out by China Energy Investment Corporation (CHN Energy) and has a nominal capacity of 1 GW. As explains People’s Dailythe official newspaper of the Central Committee of the Communist Party of China, is China’s first gigawatt-level offshore photovoltaic project and currently the largest offshore solar installation in the world. This is what the Shandong plant looks like. Via: People’s Daily The context: why at sea. Because land space near its large coastal cities is a precious commodity. The Chinese government has a policy of red line to safeguard land used for agriculture and solve the line “Hu Huanyong Line“: while its great solar and wind potential is concentrated in the west, in the Gobi Desert and Inner Mongolia, the megacities and their most powerful industrial fabric are in the east. China is already developing parks of renewables in their deserts, but running Ultra High Voltage lines is very expensive, involves losses along the way and crosses complicated orography. The logical but technically infernal solution is to jump into the water. Until now, floating solar energy was limited to calm waters, such as what Germany is doing with its lakesbut China is another story. The open sea brings salt corrosion, typhoons and waves. Why is it important. Because China’s coastal provinces such as Shandong or Jiangsu constitute large centers of industrial consumption. Generating energy right there avoids those transportation losses of thousands of kilometers from the Gobi desert. If it works within the expected design parameters and the maintenance costs are affordable, it will be a good boost to take advantage of the coasts within the energy transition process from fossil to renewables. The panels are simply colossal. Via: X from People’s Daily A prodigious work of engineering. We are talking about an area of ​​more than 1,200 hectares where 2,934 enormous marine photovoltaic panels are located with standardized dimensions of 60 meters long and 35 meters wide. And they are not drifting panels: it is a large infrastructure designed to withstand extreme conditions ranging from storms to freezing water. In addition, it is hybridized: under the panels the project integrates fish farms, that is, producing electricity above and fish below. This type of combination is not new, as in Guizhou province there is a giant solar plant in whose basement mushrooms are grown. Shandong is aquavoltaic and Guizhou is agrivoltaic. Some numbers that make you dizzy. This installed power of 1 Gigawatt is similar to that of a modern nuclear reactor, so that according to estimates, it will be capable of producing 1,780 million kWh of energy that will be fed into the grid each year and thus supply 2.6 million homes in the region. approximately 60% of your demand. According to the estimates of the engineering company behind it, 1.3 million tons of carbon dioxide will no longer be emitted.

China wants to win the military space race and that is why it is working on a humble project: a space destroyer

by

China has underway a space project worthy of ‘Star Wars’. In another context, it could sound like a tremendous exaggeration, but only one thing has to be said: the image that crowns this article belongs to a propaganda video from the Nantianmen Project. Specifically, it is the Luanniao, a larger space aircraft carrier than any aircraft carrier and able to throw hypersonic missiles and unmanned space fighters. More than terrifying, for some, it is simply high-tech theater. Nantianmen. First of all, you have to separate concepts. Nantianmen is a Chinese air force project that began in 2017 focused on the design of a global defense system. This includes practically everything we can think of such as fighters, weapons, autonomous vehicles, transport and launch platforms. It is a program that seeks to explore the paths that Chinese military aviation may have in the future, and it must be understood that, within Nantianmen, there are two types of designs: those that have been brought to the real plane through models and those that are on paper. An example of the first is Baidi, a manned aircraft that would become the jewel in the crown of the People’s Liberation Army Air Force. And an example of the second is the monstrous destroyer Imperial Chinese. Luanniao. The video that I leave above these lines is the one that the state channel CCTV published a few days ago in which we can see… a lot of 3D elements doing movie things. In certain fragments the Luanniao appears, but it is not the first time that this space aircraft carrier can be seen. As pointed out South China Morning Postin 2018, shortly after the project started, the AVIC Global Culture Communication Company – a subsidiary of the Aviation Industry Corporation of China – showed a conceptual model of the Luanniao at an air show. We now have some more details thanks to the most recent CCTV broadcast. According to the network’s data, the Luanniao will make any conventional aircraft carrier look ridiculous: 242 meters long. 684 meters wingspan. Weight of more than 100,000 tons. Capable of carrying 88 unmanned Xuannv fighters both inside and outside the Earth’s atmosphere. And a full weapons team, with particle acceleration cannons and hypersonic missiles. To give us an idea, the American aircraft carrier Gerald R. Ford It measures 337 meters by 77 meters. Pride. In the same video a model of the Baidi appears, a variable geometry wing aircraft that, as we say, seems to be the banner of Chinese aerospace innovation. In fact, the Asian giant is testing its new generation of both combat-ready fighters like those focused on air supremacy and reconnaissance. But, obviously, the one that attracts the most attention is Lunniao. From the network, it was commented that the aircraft carrier will become operational in two or three decades, and military analyst Wang Mingzhi, from the PLA Air Force Command College, affirms that technologies such as those of the Nantianmen Project reflect both the “expectations for future aerospace and space superiority and the directions being pursued to safeguard national security.” “It is not a question of whether they can be achieved, but rather which ones will be done first and when they will be implemented,” pointed out. “China is creating the impression that it is working on technologies that no one else can achieve. It is still ‘Star Wars’ material to inspire the Chinese audience” – Peter Layton Arching an eyebrow. Now, Western analysts are not so optimistic about something that has been described as mere propaganda rather than practical weapons development. Attacking the more earthly issue, defense analyst Peter Layton of Australia’s Griffith Asia Institute point Yes, the Luanniao would surpass both current defenses as storms when flying at an altitude higher than that which surface-to-air missiles and conventional fighter aircraft can reach. The “but” is that the technology to remain suspended at the edge of the atmosphere and launch missiles from there is science fiction. Layton comments that “it would require enormous amounts of fuel and propulsion mechanisms that have not yet been created,” ensuring that China has between 10 and 15 years left to develop the rocket technology necessary to put such an aircraft carrier into orbit. In D.W.space analyst Heinrich Kreft describe the project as “completely unreal from today’s perspective,” but he does not say that it is smoke because “much of what was fiction 20 or 30 years ago is real today.” Other analysts closer to the United States see the Luanniao as something with a single objective: to make the world believe that China has the technology to build this while hoarding resources to do other things. The undeniable. Whether it is psychological warfare, excessive ambition, smoke or something it is really working on, the undeniable thing is that China is taking giant steps in the new space race and weapons. We have already mentioned that they are accelerating the development of combat aircraft with stealth capabilities capable of standing up to whatever the United States deploys near its waters, but they have also joined that “first come, first served” space policy. Beyond satellites and systems that are a threat to security in space – according to the United States – they have been developing satellite technology for years. autonomous spacecraft and of reusable rockets with LandSpacethe answer to SpaceX’s Starship. But, in the end, all that is much more realistic than the enormous ship of 120,000 tons and more than 600 meters in span. But, as Kreft says, 30 years ago we also thought that current vehicles They were science fiction… Image | CCTV In Xataka | The US operation in Iran has staged one of the most impressive milestones of military engineering: the B-2 Spirit

China has spent 2025 putting things into orbit. Now they have gone further by launching a reusable space plane

by

Where I said ‘Mars’, I say ‘Moon’. For years, Elon Musk and SpaceX have maintained that colonize Mars It was humanity’s next great leap. While others (and NASA itself) considered the Moon still interesting, SpaceX looked down on her. Until recently, whenThe company has taken a step back recognizing that colonizing the Moon is easier than Mars. And of course, on the other side of the world we can have an explanation: China has the Moon in its sights. And they have just done another test with their mysterious reusable ship. The test. Last Saturday, and in the most aseptic way possible, China launched a reusable spacecraft. This was confirmed by the state news media Xinhua through an release Which leaves more questions than answers. Officially, we only know that, from one of its multiple launch bases, the country launched the vehicle on the back of a Long March-2F rocket. Mission? “The experimental spacecraft will carry out technological verification of reusable spacecraft, providing data and technical support for the peaceful use of space.” What technologies? Why do you want to know that, good night. TOP SECRET. This vehicle it’s not new. In fact, this would be the fourth trip since 2020 of an experimental ship whose characteristics are being kept in a state of absolute secrecy. On the first trip, this model would have been orbiting the Earth for two days. In 2022 it was launched again and returned in 2023 after 276 days going around. And in September 2024 there was another launch that returned after 268 days. As we say, the secrecy is total, so we do not know what type of vehicle it is, but there has been speculation that it may be the answer to the X-37B robotic vehicle of the United States Air Force. Neither Reuters nor Xinhua comment that it could be the Shenlong, the Chinese ‘Divine Dragon’ which is the competition of the aforementioned X-37B. Because if we talk about reusable rockets like SpaceX’s Falcon, China also has an answer: the LandSpace. They don’t stop throwing things. Beyond the reusable ship, China has gotten right into the space race. Like Europeis another of the countries that seeks space sovereignty, and one of the toughest tests was carried out at the beginning of December. To test the overload capacity of its systems and analyze whether they can handle several missions at the same time, in early December, China completed four space missions in four days. In total, there were 80 orbital launches in 2025, surpassing the previous record of 68 launches and achieving with this proof of this something only within the reach of the current SpaceX. And it seems that 2026 has started as last year ended. Target: Moon. Among China’s medium-term objectives is to take astronauts to the Moon before 2030. They want to compete against the NASA and its Artemis mission for establish a research base on the satellite while they finalize the building your own space station. The Moon has become that last piece of cheese on the plate, but instead of giving it up, the great powers want to get hold of it. Reason? Its great value to carry out experiments to expand sovereignty on other planets, but also with regard to resources that can be exploited and sent to Earth refers.

that Russia has been knowing all its steps from space for years

by

After the Cold War, space was conceived by Europe more like an extension of scientific cooperation and the civil market than as a domain of strategic confrontation. Thus satellites designed for television, meteorology or navigation were deployed at a time when the main concern was technical reliability and cost, not the deliberate hostility of other States. While Washington and Moscow kept alive military logic inherited and China began to build its own, Europe was establishing a functional, open and trust-dependent spatial architecture. The latest finding reveals a “big” underlying error. Hybrid warfare reaches orbit. Yes, for years, Europe assumed that space was a technical and relatively stable domain, ultimately protected by its civil and cooperative character. It so happens that recent Russian satellite activity has broken that illusion. As? In parallel with sabotage of submarine cables and other covert operations, Moscow appears to have moved its hybrid war to space, taking advantage a critical blind spot: Many European satellites were launched decades ago without modern encryption systems or advanced protection. This vulnerability, ignored for years, has turned the geostationary orbit into a new silent front where missiles are not needed to inflict strategic damage. Luch-1 and Luch-2. There is much more, since the Financial Times discovered exclusively this morning that Western authorities have been monitoring the movements of two Russian space vehicles for some time, Luch-1 and Luch-2which have performed unusual maneuvers, getting dangerously close to key European satellites and staying next to them for weeks. Since its launch in 2023, Luch-2 has approached at least 17 satellites that provide essential services to Europe, Africa and the Middle East, a pattern that, according to analystsleaves no doubt about its purpose. These approaches are not accidental: they seek to position themselves within the narrow cone of data transmission between ground stations and satellites, an ideal position to intercept signals and study their internal workings. The critical failure. The most disturbing revelation is that some of the most sensitive information circulating through these systems, including the command links that allow orbit adjustment, it is not encrypted. Put another way, that means Russia could not only have spied on civil and government communications, but also recorded enough technical data to imitate legitimate operators from land. With that knowledge, for example, a hostile actor could send fake orders to alter the orientation of a satellite, take it out of service, misalign it or even force its fall or uncontrolled drift, without the need to physically destroy it and without leaving a clear attack signature. A strategic Achilles heel. Although the Luch satellites They do not seem to have the direct ability to interfere with or destroy other devices, their value lies in the accumulated knowledge: how European satellites are used, who operates them and from where. This intelligence allows us to prepare more discreet attacks, such as Selective interference or cyber attacks coordinated from the ground, and reinforces the idea that spatial networks are the true Achilles heel of modern societies. As Russia expands its reconnaissance program with new maneuverable satellites and Europe begins to come to terms with the magnitude of the problem, the message is clear: hybrid war It is no longer fought only at sea or on dry land, but also 35,000 kilometers above our heads, the point where Europe has just discovered that had been exposed for years.

This is the impressive interactive map to see the Earth in 4K live from space and monitor satellites

by

Cartographically speaking, our planet is fascinating: its evolution over time, what it’s really like taking into account the precision of physics and of course, per se: the mountain ranges, the irregularities of the coasts, the tectonic plates… all of that looks great from space. And be careful, because the space that surrounds the Earth It is full of satellites: only Starlink ones around 15,000 units. But satellites allow us to have a fabulous view of the earth. And in fact, some of the main space projects that monitor the Earth have their recordings open, without going any further, what the International Space Station “sees” either NASA events They are available to anyone. The problem is that not everyone knows it, nor do the tools shine for having a clear and intuitive interface. So to someone who loves astronomy it occurred to him to create it to follow from satellites to shooting stars or racing cars. SatellitesArg Although you can see the Earth from space live and in 4K without doing anything, it is worth setting your location for a more personalized and precise experience of everything it offers. From here, there are several ways to select a satellite to follow, some as intuitive as tapping on “Satellites” and selecting from the list (there are some as popular as Starlink or BlueWalker 3) to see, for example, the ISS live camera. However, you can also save them to your favorites. Another interesting option is “Visible Passage”, which is what happens when a satellite crosses the sky illuminated by the Sun while it is night in your location. To do this, simply select a specific satellite, open it on the map and click “Visible path”. Within “Best steps” those satellites that will be highest and brightest in the coming days are shown. Likewise, there are filters to, for example, see only the steps at dawn or dusk. The “Radar” option is used to locate a specific satellite, something especially interesting if done from a mobilesince with the help of the compass you can hunt it at some point in the sky. You can also view those that are nearby, use augmented reality to superimpose the trajectory using your phone’s camera. Although you can see in real time, you can also go back to monitor past trajectories and have access to astronomical events, the phases of the moon and even have a map of the stars in the sky. But even if you don’t take advantage of all those functions, the option to see the Earth in real time in 4K by tapping on “ISS Live Camera” It is simply spectacular.

Blue Origin’s space tourism numbers have been leaked and they are crazy

by

A few years ago I saw a Spanish civilian cross the Kármán line leaving our planet was a generational event. Today, space tourism is about to normalize what was extraordinary and we have the clearest example in Alberto Gutierreza 42-year-old businessman from Valladolid and founder of the platform Civitatis who this Thursday managed to be the fourth Spaniard to theoretically reach space. His story. He did it on board the NS-38 mission from Blue Origina flight of just ten minutes that takes off and lands in Texas, but which represents another milestone in the private space race and consolidates the profile of the “tourist-astronaut” with a high heritage behind him. Because the truth is that it is not something very economical. 10 minutes. Takeoff took place at 10:26 CST (16:26 Spanish peninsular time) from the Blue Origin Launch Site One in Van Horn, Texas. The ship used was, once again, the reusable New Shepard system, a rocket designed specifically for suborbital tourism. All this with a plan that has followed the “Swiss clock” script to which we are accustomed in these missions. At the moment of launch the ship’s engine accelerated until it exceeded the March speed 3, and when it was already at a good altitude, the capsule was undocked and continued to ascend up to 106 kilometers above sea level, exceeding the Kárman line which is located at 100 km altitude. Weightlessness. But the experience sought with this type of attraction is to experience the phenomenon of weightlessness for a few minutes. Specifically, there were 3 minutes in which Gutiérrez was able to unhook himself from his seat belt to observe the curvature of the Earth while he was literally floating in space. It hasn’t been cheap. Although Blue Origin maintains official secrecy about the dynamic prices of its tickets, the sector has quite clear figures. And to enjoy these three minutes of weightlessness you only have to pay $150,000 just for admission to reserve your seat. But it does not logically stop here, since industry sources and leaks Previous estimates place the total cost of the ticket at around one million dollars. A price that not only pays for experience, but also for status. More and more difficult. With this type of space excursions aimed at the richest on our planet, the truth is that an interesting debate opens up about the label of “astronaut.” Although technically the Kármán line has been crossed with this trip, the FAA modified its criteria in 2021 to narrow it down much more. In this case, it no longer provides commercial astronaut wings to space tourists, but opts for a simple registration on its website. That is why for the agency, being a passenger is not the same as being an operational crew, although surely for all those who participate here it is a great life experience that is undoubtedly spatial. It’s not the first. As we have said, with this flight, Alberto Gutiérrez puts his name on a very short list. Before him, only three Spaniards had crossed the space border: Pedro Duque, Michael López-Alegría and Jesús Calleja. Although it is clear that this is an experience that is quite limited to those people who have a large wealth and decide to invest it in a unique experience. Last minute surprise. The NS-38 mission has not been without logistical setbacks. The original crew of six underwent a change just three days before launch, as Andrew Yaffe had to retire due to illness on January 19, being replaced by Dr. Laura Stiles. And there was luck with this replacement, since its inclusion allowed the launch date to be maintained, which had a very limited launch window, in order to guarantee its safety.
