The Earth turned on its great geological engine billions of years earlier than we estimate. We know it from a microscopic crystal

by

For a long time, textbooks They have painted the primitive Earth like a ball of infernal and static magma, being a “lid” of inert rock where life or complex geological movement was impossible. Specifically, it was thought that the plate tectonicsthe engine that shapes the continents and recycles our planet’s nutrients, had taken much longer to start. However, we were wrong. How he did it. Science, in a recent article, has just put on the table the definitive evidence that indicates that the Earth began to move much earlier than we believed: at least 3.3 billion years ago, and most likely, more than 4 billion ago. And the key is not in the gigantic mountains under our feet, but in small fragments of glass smaller than a grain of sand. And if we want to travel in geological time, you have to go to jack hillsin Western Australia, where the oldest known fragments of terrestrial rock are found. The protagonists of this story are zircon crystals, extremely resistant minerals that act as authentic geological hard drives. The interesting thing is that, when they form, they trap isotopes and tiny amounts of other elements inside that tell us exactly what the environment was like at the time of their crystallization. The results. According to detailed analysis that collects Natureand supported by key works such as those published in the prestigious magazine PNASthese S-type zircons hide unmistakable geochemical signatures. Specifically, they reveal that, instead of a static and dead Earth’s crust, subduction processes already existed. That is, the oceanic crust was already colliding and sinking under other plates, melting back into the Earth’s mantle. A double life. But researchers have not limited themselves to looking at a specific era, but have traced the proportions of trace elements such as uranium, niobium or scandium in different zircons from Australia, Greenland and South Africa. Here they observed that during the Eoarchean, the Earth did not have a single geological behavior. Instead, it had two tectonic regimes. The first of these, known as a ‘stagnant lid’ with areas of crust dominated by plumes of oceanic magma that simply pushed upwards. On the other hand, it also had the ‘moving lid’ zone, which were active zones where volcanic arcs were already forming and there was subduction, very similar to modern plate tectonics, recycling the Earth’s crust. But there is more. As if that were not enough, other published studies in Science and Geology have contributed even more pieces to the puzzle, such as the transform faults in the Pilbara Craton of Australia that show horizontal movements 3,000 million years ago, and even inclusions of fresh water in zircons from more than 4,000 million years ago, which suggests that there were already emerging continents interacting with the atmosphere and the water cycle. It changes everything. Knowing that plate tectonics started so early is not a mere geological whim, since tectonics is the Earth’s thermostat: it regulates the carbon cycle, releases fundamental gases into the atmosphere and creates the necessary environments for the chemical breeding ground. In this way, if more than 4,000 million years ago our planet was already recycling its crust, having primitive continents and fresh water, it means that the conditions for life to emerge occurred much earlier than what science books dictated. Once again, the Earth shows us that, from its most remote beginnings, it has always been a living world.

The idea of ​​​​harvesting solar energy from space may sound like science fiction and, furthermore, it would make all the sense in the world for it to do so: Isaac Asimov already wrote about it in his story “Reason” of 1941. However, the scientific community has been ruminating on it since 1968, when American aerospace engineer Peter Glaser published the first technical article on this concept in Science magazine. Since then, entities such as NASA, the California Institute of Technology or the Japanese Japan Space Systems have explored the possibility. However, Japan is the closest to achieving what no one has yet achieved: generating electricity in space and sending it directly to Earth. Context. To begin with, the cost of launching rockets has become enormously cheaper since the idea began to be glimpsed. On the other hand, we are in the midst of global energy transition from mobile fuels towards renewable sources where there is one that stands out: solar energy. But solar energy requires space to deploy parks with photovoltaic panels, which is why China is choosing to assemble them in the open sea, Germany explores with lakes and Japan… Japan is an island with little space. On the other hand, solar energy has another important limitation: it only works when there is sun. However, in space there are no clouds or night and the sun shines without stopping. Why is it important. Because the business models that J-spacesystems is developing They are designed to generate about one gigawatt of constant power. To better understand the dimensions of that figure, it is the energy necessary to cover 10% of the consumption of a megacity like Tokyo and is also equivalent to the power of a standard nuclear reactor. We are facing a paradigm shift in energy density: a solar plant in space capable of ‘redirecting’ its energy beam towards different receiving antennas according to demand, whether within the country itself or the world. This opens the doors to sending energy to areas in emergency situations or meeting consumption peaks, something that is not possible with the current infrastructure. Japan Space Systems Scheme What is Ohisama. Ohisama is sun in Japanese and it is also the name of a Japanese satellite of 180 kg that has an integrated solar panel approximately the size of a door (70 cm x 2 m) is to orbit at 450 km altitude, where it will be able to generate 720 watts of electricity that it will then convert into microwaves. It will then launch those microwaves up to a 64-meter antenna in Nagano. If the energy arrives, it will be converted into electricity. The ultimate goal: light an LED. Yes, all this to light a light bulb. In reality, the important thing is not so much the power transmitted in the test (which is very small) but rather being able to validate that the transmission works through the ionosphere. It is the test of truth: in 2024 Japan has already tried it successfully from a plane seven kilometers high, but this is already a jump to a real orbit that will allow everything to be scaled (if it goes well). When and where. From now on, literally: The window for the third attempt began on February 25, with a backup date until March 25. The launch site will be the Kii Spaceport in the city of Kushimoto, Wakayama Prefecture, the first private rocket launch site in Japan. What comes next. If the experiment goes well, Japan would go on to implement those commercial models, which consist of 2.5 square kilometer solar panel arrays in geostationary orbit at 36,000 km with 4 km diameter receiving antennas on the ground. The estimated date for its commercialization is from 2040 and in addition to supply on land, Japan has in mind to use the system for energy supply in lunar exploration missions. Why is it so difficult. The first immediate risk inherent to the project is Kairos 5 of Space Onethe private Japanese company in charge of putting Ohisama into orbit: the two previous launches failed. Third time lucky? The possibility of another company from outside doing it is not an option (at the moment). As explains Yanagawa of J-spacesystems: “Although overseas rockets were an option, we selected Kairos following the national policy of supporting Japan’s private sector launch capabilities.” But even if the launch were successful, the big problem will be microwave diffraction: transmission over thousands of kilometers risks scattering, requiring huge transmitting antennas and very precise phase control. Japan has been working to solve this bottleneck for decades.

China’s brutal dominance in rare earth production in the last 30 years, in a revealing graph

by

There are few strategic natural resources as important as gas, gold or oil, but there is one that is less known and that is decisive in practically any industry and therefore, also in geopolitics: the rare earthwhich are neither earths nor rare (in fact, they are a list of 17 metals). The state that has enough rare earths in its territory and the capacity to extract them will have much to gain to become a power. Well, if you can cough China, the absolute leader in rare earths so much in reserves as in production. A picture is worth a thousand words. But today the power of China is discussed is one thing and another if the Asian giant started by winning the game. Spoiler: no. The United States Geological Survey It has a very complete database where to visualize production by country from 1994 to the present (among other information), but more than a table, it is better seen with images. Thus, at a glance you can see its beastly hegemony in this chart from Visual Capitalist from 1994 to 2024. 30 years of rare earth production. Visual Capitalist An animation still counts more. The Visual Capitalist illustration shows Chinese superiority, but the evolution of rare earth production by country is better seen with an animation showing its meteoric rise because yes, the global rare earth industry has been profoundly transformed in the last 30 years. In just three decades, China has gone from having a 47% quota to almost 70% of the 400,000 metric tons produced today (by the end of 2024). Or what is the same, going from manufacturing 31,000 metric tons to 270,000 metric tons, something that can be seen in this animation by Global Times and Valiant Panda: Tap to see the animation. Production by country of rare earths from 1994 to 2024, Global Times How America Lost Control. It’s worth stopping the animation at the beginning, because in the 90s the United States was the world’s largest producer of rare earths and Mountain Pass was its main plant for obtaining them. Its average extraction was around 20,000 – 22,000 tons. And then, in 1997, came the Mountain Pass environmental disaster: a burst pipe in the eponymous mine that contaminated the Movaje Desert with toxic radioactive waste. Between the disaster and the subsequent lawsuits, production suddenly fell to 5,000 tons between 1998 and 2002. It would then fall to 0 in the 2000s. It would be in the 2010s when it began to recover: now the United States is around 46,000 metric tons. As Rocío Jurado sang, now it’s too late, lady: it was also in the 90s when China went into steamroller mode. The unstoppable rise of China. That China has come to dominate world production hides several keys. The first, the ability of its suppliers to offer lower prices Thanks to state aid, laxer environmental standards and cheaper labor made possible costs that the West could not cope with. China had the resources, but its victory came because it was able to build an entire industry while the rest of the world watched. Producing the raw mineral is only the first step, then it must be separated to achieve a high degree of purity (between 95 and 99%, depending on the application) in a complex, expensive hydrometallurgical process that, as we have seen, leaves radioactive waste along the way. Where it still dominates more: refining. Because although China has a share of almost 70% of world production, its dominance is even more overwhelming in refining: it produces around 90% of world refining. In fact, other countries such as Australia or the United States extract minerals, they turn to China for refining. If there is no refining industry at the level of extraction, there is no sovereignty. Other faces. Trump wants to step on the accelerator of national mining and expedite permits, the EU also seeks its strategic sovereignty with laws such as the Critical Raw Materials law and its application in places like Per Geijer’s Swedish megamine. We have already talked about Australia, which at least until this year It will depend on China for refining those 16,000 metric tons that have been around in recent years, but there are other countries that have joined the race. But while the Global Times animation focuses on great powers, the Visual Capitalist graph reveals new players in the industry such as Myanmar, Thailand or Nigeria, especially focused on more scarce and valuable elements. However, their supply chains are unstable and have their own regulatory and geopolitical risks.

We know it as “the red planet”, but 3.37 billion years ago Mars was almost as blue as Earth

by

The mystery of Mars and water has a new chapter. The missions like Curiosity in the Gale crater they show clear evidence for the existence of liquid water lakes for thousands or millions of years. That climate models show that the early Mars It was a cold place. with temperatures significantly below the freezing point, it was elucidated with seasonal ice shields. However, among the pending subjects of Mars astronomy is knowing how much there was water and when was there. Mars was (half) blue. A recent study published in the scientific journal npj Space Exploration echoes the discovery of a “tide line” that explains that there was once an interconnected water system. Ignatius Argadestya, the lead author of the study, explains that although today Mars is a dry and reddish planet: “our results show that in the past it was a blue planet similar to Earth.” In fact, they have been able to demonstrate the existence of the deepest and most extensive ocean that has existed on Mars to date, account the scientist that half the red planet was once blue: “an ocean that extended across the planet’s northern hemisphere.” Valles Marineris in Hi-Res The “deltas” of Mars. More specifically, they have investigated geological formations called deposits with steep front located in the region of Valles Marineristhe largest canyon system in the solar system. Using very high resolution images from Cassis of the European Space Agency and the CTX and HiRISE from NASA (the latter provides a maximum resolution of about 25 to 30 centimeters per pixel), have been able to identify these deposits with identical morphology to the river deltas that we see in rivers such as the Ebro or the Danube when they flow into the sea. Thus, on Mars there was a time when water flowed from the mountains through branching channels until it reached a kind of lake or sea, where sediments were deposited. These deltas end in an abrupt step that is located at exactly the same altitude at different points on the planet, between -3750 and -3650 meters with respect to the reference level of Mars. About 3.37 billion years ago. This is not a geological coincidence, it is that at one time there was a body of water like a sea that maintained a stable level for a long time: it is a mark of the shore of a primeval Mars, since these deposits were formed between the Late Hesperian and Early Amazonian periods. According to the research team, that was the time in the history of Mars with the greatest availability of liquid water on its surface. Why is it important. Already had applied previously the existence and size of this Martian ocean, but its conclusions come with more precise and direct evidence. In addition, they have been able to determine when the water peak occurred on Mars. The deltas found constitute a magnificent base to study their sediments in depth in search of traces of life because where there is water, there could be life. On the other hand, among the next steps is to understand how Mars went from having an ocean that occupied half the planet to being a frozen desert. In fact, there are already clues: the research team detected desiccation cracks and dunes on these channels, which indicates that after this aquatic period, there was a progressive drying until they became arid.

In 2024 we feared that the asteroid YR4 would impact the Earth. Now NASA believes the Moon is threatened

by

For a few weeks at the beginning of 2025, the name 2024 YR4 became an absolute protagonist among the main institutions around the planet. It was no wonder, since this object, with an estimated size between 40 and 60 metersreached the level 3 on the Torino scalea milestone that we have not seen for a long time and that implies a probability of collision greater than 1% with the capacity to produce devastating local damage. We are saved. After this fear, science has managed to reach the conclusion that the Earth is safe now. However, the story of 2024 YR4 is not over, since the latest models suggest that, although it will avoid us, there is a non-negligible probability that it will end up crashing into the Moon. How we knew. Initially, NASA’s Center for Near-Earth Object Studies (CNEOS) held his breath in early 2025. The first observations showed a worrying scenario for the year 2032 with this possible impact, but the moment more attention began to be paid to this object it was seen that it was not going to end up on Earth. The key to being able to breathe a little calmer again lies in the ‘shoulders’ of the James Webb which began making observations in May 2025. The space telescope made it possible to refine the asteroid’s orbit with a 20% precision improvement, confirming that there is no risk of impact against our planetnor an orbital alteration of the Moon that could affect us secondarily. But by closing a door, the JWST opened a fascinating and destructive window: the probability that 2024 YR4 will impact the Moon has risen from 3.8% to 4.3%. The lunar judgment. According to studies recently published on arXiv, the key date is December 22, 2032. That day is where there is about a 1 in 23 chance that we will see a violent spectacle on the lunar surface with an impact that would release an energy of 6.5 megatons of TNT. This is something very relevant, since this great energy would generate a crater approximately one kilometer in diameter and the ejection of 100 million kilos of lunar debris with a cloud of material equivalent to the weight of about 20,000 elephants. From Earth. Logically, this impact, although it does not occur on the planet, the truth is that it will have important consequences and not exactly physical ones, but rather a visual phenomenon. The debris that will be ejected from the Moon could enter the Earth’s atmosphere some time later, generating an unprecedented meteor shower caused by a secondary impact. The use of technology. Over time, the European Space Agency has also validated this data, placing the size of the object more specifically between 53 and 67 meters and confirming the 4% probability of having an impact on the moon. Although logically we also have a 96% chance that it will completely pass from the Moon. But this asteroid has had a very positive point: it has vindicated the need to improve space detection tools. And right now these objects are hiding in the “blind spot” of the sun’s glare, although with this one we were lucky that the ATLAS system in Chile managed to detect it. A future mission. Given this limitation that we have, the ESA has seen it necessary to activate the NEOMIR missionsince if it had already been active, it would have detected the asteroid a month earlier, offering vital reaction time if the threat had been against the Earth and not against the Moon. And now what. For now, we have to wait. The asteroid has moved away in this case and will not be in an optimal position to make an observation again until 2028. It will be then that astronomers will be able to refine this 4.3% probability and tell us definitively whether we will spend Christmas 2032 looking at the Moon to see how a new crater forms live.

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.

We know that the Earth has been hit by 80,000 meteorites. For some reason, most end up in Antarctica

by

If we look at the global statistics of finds of meteorites on our planet We may think that they are distributed homogeneously throughout the territory, but the reality is very different. Official data indicates that of the approximately 80,000 meteorites cataloged all over the world, more than 50,000 have been found in Antarctica… And this raises a big question: does Antarctica have something special about having so many meteorites? A contradiction. Although we talk about 60% of the meteorites that have been found on Earth come from Antarcticacollision theory tells us another. Specifically, physics, which tells us that meteorites fall randomly and uniformly throughout the planet, so Antarctica does not receive more impacts than the Sahara Desert or the Pacific Ocean. So… Why do we find so many meteorites on the frozen continent? The answer lies in a perfect combination of glaciologyvisual contrast and a natural “trap” that is now, ironically, being sabotaged by climate change. The conveyor belt theory. To understand why Antarctica is the great archive of the solar system, you have to understand how ice moves. And the secret is not in how the rocks fall, but in how the ice delivers them to humanity. To do this, we must go to glaciological models and studies from programs such as ANSMET, where they point out that Antarctica It is a real meteorite conveyor belt. The process. In this way, a meteorite when it falls inside the frozen continent buried deep in the ice sheet. Once here, the natural flow of the glaciers will push the ice that stores the rock inside from the center towards the coast. At certain points, the ice encounters barriers beneath the glaciers, such as hidden mountains that slow its flow and forces the ice to return to the surface. And this is where the famous katabatic winds come into play, which are truly fierce and dry with a force capable of eroding the upper layers of the ice from solid to gas. The result. It is what scientists call the ‘Meteorite Stranding Zone’ (MSZ) or blue ice areas. It is nothing more than the part of ice that has been worn away, but has not affected the rock it stored in any way. That is why over time, meteorites that fell thousands of years ago and traveled trapped in the depths of the ice now appear on the surface as if someone had put them there. A contrast trick. Logically, finding a meteorite among a pile of red ones can be somewhat complicated in our environment. But when we talk about a black rock on a white sheet like ice, the truth is that visually it is easy to find it. That is why this contrast is the best ally that meteorite searchers have. The preservation. But beyond the fact that finding a rock the size of a walnut in the middle of the jungle is a really complicated task, it must be taken into account that humid climates degrade the meteorite quickly. Something that does not happen in Antarctica, which is technically a polar desert. The dry environment it has acts like a real freezer which preserves the samples almost intact for millions of years. This allows scientists to recover not only the rock, but pristine information about the origins of the solar system. And that is why all these factors together make it more common to find more meteorites in this location than in others, and not because there is a predilection for falling here. An invisible threat. As pointed out a study published in Nature, we have a serious problem on the table: We are losing about 5,000 meteorites a year. Intuition would tell us that if the ice melts due to climate change, more rocks would emerge. But the opposite is true due to the thermal properties of the meteorites themselves. Being dark rocks (and many of them metallic with high thermal conductivity), they absorb solar radiation much more efficiently than the surrounding ice. Even at subzero temperatures, the rock heats up enough to melt the ice just below it. This causes the meteorite to sink and create a small pool of water that refreezes them, burying the rock out of sight of researchers or satellites. Thermal models suggest that this disproportionately affects iron meteorites, which are especially valuable for understanding planetary cores, causing us to have many more chondrite or rocky meteorites. Race against time. Humanity has so far managed to recover 23,000 meteorites, giving us a large cosmic library that allows us to better understand everything around us. The problem is that the clock is ticking, and the most important part of the archive is beginning to sink, so now the most important thing is to hurry up to get the most valuable meteorites for us.

the first pilot line to recycle rare earth magnets

by

Europe has learned an uncomfortable lesson in recent years: the energy transition does not depend only on political will or investments in renewables, but on materials that it does not control. After achieving —not without difficulties— reduce its dependence on Russian gas, the European Union is facing now to a deeper, more structural vulnerability: China’s near-absolute dominance over critical metals and, in particular, rare earth permanent magnets. Without these magnets there are no electric cars, no wind turbines, no advanced robotics, nor much of the defense industry. However, France has taken a step that goes beyond political discourse and can turn the tables. The inauguration of a pioneering pilot line. The Orano group and the Alternative Energies and Atomic Energy Commission (CEA) inaugurated at the CEA-Liten facilities in Grenoble, a pilot line dedicated to the recycling and remanufacturing of high-performance permanent magnets from rare earths. As Orano explained, The infrastructure has a pilot capacity of up to four tons and is equipped with technologies representative of an industrial scale, operated by a joint Orano–CEA team. The technical results of the project are expected by the end of 2026, with a view to subsequent large-scale implementation by an external industrial operator. A response to a critical dependency. The importance of the project goes far beyond its technical dimension. Permanent magnets based on neodymium-iron-boron have become key pieces for the European industrial future, but today the EU matters more than 95% of those you need. and the demand it doesn’t stop growing: The market has grown from around 250,000 tonnes of magnets this year to around 350,000 in 2030, with a growing proportion of high-performance applications. The problem is not only volume, but control of the value chain. China not only concentrates a good part of the world reserves of rare earthsbut between 70% and 90% of its processing and up to 99% in the case of heavy rare earths. This gives it a capacity for geopolitical pressure that has already translated into export restrictions and real supply interruptions for European industries. In this context, the Grenoble pilot line is fully part of the Critical Raw Materials Actwhich sets the goal that at least 25% of critical raw materials are recycled in Europe by 2030. “Short circuit” recycling. This is what the technological core of the project is called. Unlike traditional recycling – the so-called “long loop” – this approach allows rare earths to be recovered directly in metallic form from magnets at the end of their useful life, without going through complex chemical steps of dissolution, reoxidation and reconstitution. “This recycling offers an optimal compromise between magnetic performance, circularity and decarbonization,” explains Benoît Richebé, project manager for Rare Earths and Magnet Recycling at Orano, in statements collected by El Periódico de la Energía. The approach allows critical metals to be directly reused and reconstructed new high-performance magnets, suitable for demanding applications such as electric vehicle traction motors or offshore wind turbines. Orano defends, however, a hybrid approach. According to Richebé, short loop and long loop recycling are complementary, and Europe must be able to have both to build a flexible and resilient industry. The mixture of secondary raw materials with new alloys ensures maximum technical performance. Beyond the pilot. Currently, the recycling rate of rare earth magnets in Europe is just 1%, according to data cited by the German Mineral Resources Agency (DERA). For years, the combination of low prices for Chinese primary products and irregular availability of waste has slowed the development of a large-scale recycling industry. However, how RawMaterials collectsthe largest magnet recycling plant in Eastern Europe, operated by Heraeusand in the south of France the company Caremag plans to establish a rare earth recycling and refining plant in the coming years. However, here comes the key point: the Orano and CEA project is also supported by two collaborative consortia financed by France and the European Union —Magellan 1 and Magnolia 2—, which develop complementary technologies for the manufacture of magnets from recycled critical metals. One of the differentiating elements of the project is the application of Orano’s nuclear know-how to the magnets industry: powder metallurgy, processes in controlled atmospheres, sintering and management of highly regulated facilities. Experiences accumulated in plants such as Orano Melox, dedicated to nuclear fuel recycling, are now transferred to a key sector for electrification. A crack in the monopoly. France is not going to compete with China in production volume of rare earths or magnets in the short term. But with this pilot line, something perhaps more important has begun to be disputed: the control of industrial knowledge and processes. As Benoît Richebé summarizes“mastering the recycling of magnets will be essential for the ecological, digital and technological transitions.” It is not just about materials, but about industrial sovereignty. If the pilot meets its objectives and the processes are successfully transferred to an industrial scale, Europe could recover part of a value chain that it lost decades ago. In a world where critical metals have become instruments of power, recycling magnets is not just an environmental solution: it is a strategic act.

will go find an “Earth 2.0” on his own

by

China has stepped on the accelerator in space sovereignty and is already at cruising speed: in 2025 it has broke his record of rocket launches with 80 units throughout the year and only in December complete four space missions. It has even successfully executed a stress test to verify that they can level up. So much so that they already have in mind exploring space in search of an Earth 2.0. China’s plan to find a new Earth. This is the name of the video that the Chinese network CGTN published a few days ago in their Hot Take space. This footage details four missions that the China National Space Administration (CNSA) has scheduled within the 15th Five Year Plan of the country (2026–2030) to support its position as a first-order space power and whose spectrum is as broad as we will see below. Among these missions is a radio astronomy experiment to study celestial objects by measuring their radio emissions, in this case aimed at better understanding the hidden side of the moon; a solar observatory that will investigate meteorological conditions such as solar wind or geomagnetic storms, the construction of a space telescope that will monitor black holes and neutron stars and a satellite hunter of planets outside the solar system. The latter has an ambitious goal: to search for a planet analogous to Earth. A peculiarity of these missions is that They are run by the Chinese Academy of Sciences (CAS), an independent institution of the Chinese Space Agency and its major space projects. The CAS manages its own missions (such as HXMT or Wukong) independently and do not follow government guidelines, but are born from proposals by researchers and universities, following a low-cost and flexible model similar to NASA’s Discovery program. China is looking for an Earth 2.0 and to know space much better Hongmeng Project. This plan It intends to deploy ten low-frequency telescopes that will orbit the moon. Like other observatories focused on its hidden side, they will hear radio frequency signals from the period known as the “Dark Age of the Universe“. This time corresponds to a time of the early universe where there were no stars or galaxies or planets, only neutral hydrogen that absorbed light, creating darkness, and emitted a characteristic radio signal 21 centimeters. Why the hidden side of the moon? Essentially, because it is free of radio interference from terrestrial sources and regular emissions from the Sun. This mission is complementary to others such as that of the James Webb Space Telescope (JWST) to study those early epochs, which are currently undetectable to conventional telescopes. The Kuafu-2 solar mission. The two in its name already reveals something: there was a Kuafu-1 launched in 2022 and also known as the Advanced Space-based Solar Observatory (ASO-S). The first was launched to study the sun’s magnetic field and its phenomena, such as sudden and intense releases of electromagnetic radiation (flares) or coronal mass ejections. But Kuafu-2 will go one step further: it will be the first satellite to orbit the hard-to-reach areas of the Sun, the polar regions, thus providing data on the solar magnetic field and the dynamics of the solar cycle (which lasts approximately 11 years). With this information, the scientific team hopes to be able to predict solar storms and their cascading effects throughout the solar system. Screenshot CCTV News In search of a planet analogous to Earth. Exo-Earth is a satellite exoplanet prospecting which the show has defined as a “planetary detective on a mission to see if Earth is one of a kind.” Its objective will be to monitor thousands of stars in our galaxy in search of rocky planets of a size comparable to that of Earth that orbit within the habitable zone of their stars, that is, at a sufficient distance for liquid water to exist on their surface. An analogue to Earth. This observatory will be launched in 2028. How do the laws of physics work out there?. The fourth and last is the Enhanced X-ray Polarimetry and Timing Observatory, an international project led by the Chinese giant that combines X-ray observations with “unprecedented polarimetry and timing capabilities.” Or what is the same, the ultra-precise measurement of brightness variations over time and the study of the orientation of the oscillations of electromagnetic waves to infer the geometry of magnetic fields. If it sounds dense and scientific, that’s because it is: it helps you learn how the laws of physics apply in environments as extreme as around black holes, neutron stars, supernovae, and other astrophysical objects. Its technical proposal details that this observatory will have advanced spectroscopic focusing systems and polarimetric focusing systems. The launch is planned for 2030.

The Earth has been providing heat for millions of years and now Google wants it for something very different from heating

by

The race for artificial intelligence is no longer fought only in laboratories or chip factories. It is moving towards much more basic and, at the same time, more critical terrain: electricity. At a time when data centers are increasing their energy consumption and the electrical grid is beginning to show signs of saturation, an American geothermal startup has just closed one of the largest financing rounds in the sector. It is called Fervo Energy, it has raised $462 million and, among its investors, is Google. It is not just another financial movement. It is a clear sign of where big technology companies are looking to sustain their ambitions with artificial intelligence. First commercial project. The company has closed this financing in a Series E – one of the last phases of private investment before a possible IPO – aimed not at research, but at the deployment of large-scale energy infrastructure. The round, led by B Capital as lead investor, will serve to accelerate the construction of Cape Station, its geothermal plant in Utah, and advance the development of other projects. In other words, moving from technology demonstration to commercial production of firm electricity for the grid. In addition, the round has aroused the interest of a broad group of industrial, financial and technological investors. Among the new names are AllianceBernstein, Mitsui, Mitsubishi Heavy Industries, Breakthrough Energy Ventures and, especially significantly, Google. As reported by TechCrunchFervo has raised nearly $500 million in equity and debt in the last year alone, reflecting an unusual investment appetite for a technology that for decades was considered marginal. The Google entry. Fervo is not just a climate bet or an impact investment: it is a direct energy supplier for data centers. The company already maintains an agreement with Google to supply geothermal electricity to its facilities, something that turns the technology company into a client and investor at the same time. This move fits with a broader trend. The big tech companies they have stopped trusting only in the traditional electricity market. The explosion of generative AI has multiplied the demand for continuous, stable and emission-free energy, a profile that neither solar nor wind power alone can guarantee without massive battery backup. On the other hand, geothermal energy offers firm electricity 24 hours a day. How does the Fervo bet work? Fervo’s key It’s in your technology of Enhanced Geothermal Systems (EGS). Unlike traditional geothermal energy – which depends on natural hot aquifers – Fervo drills hot rock, injects water and creates artificial reservoirs that allow steam to be generated in a controlled manner. A direct adaptation of hydraulic fracturing and directional drilling techniques developed over decades by the oil and gas industry. It is no coincidence: many Fervo engineers come from that sector. The flagship project is Cape Station, located in Beaver County, Utah. According to the company’s planswill begin supplying 100 megawatts in 2026 and will reach 500 megawatts in 2028. One of the key factors is speed, as the company has drastically reduced the drilling time for its wells: from about a month in its first projects to a current average of about 15 days. As Sarah Jewett, senior vice president of strategy, explained, to TechCrunchapproximately half of the cost of a well depends on drilling time. Reducing it is synonymous with economic viability. AI as the engine of the new energy map. The rise of Fervo cannot be understood without the pressure that artificial intelligence puts on energy infrastructure. According to the International Energy Agencythe electrical consumption of data centers could double before 2030. An analysis by the Rhodium Group goes further and estimates that advanced geothermal could cover up to two thirds of new energy demand of these centers in the United States. Google is not alone in this race. The company is simultaneously exploring the reopening of nuclear plantsthe development of small modular reactors (SMR) and even experimental projects as solar-powered orbiting data centers. The logic is the same in all cases: ensure its own, stable, long-term electricity supply. In the words of the CEO of FervoTim Latimer: “There is a huge appetite to understand how the history of electricity demand is going to be resolved.” The answer, increasingly, lies in energy sources that previously seemed secondary. A sector that matters again. For years, geothermal energy was relegated to wind and solar energy. Today, United States live a true renaissance of the sector. The combination of new technologies, private capital, institutional support and demand from Big Tech is changing the landscape. Fervo is considered a pioneer within this new ecosystem. According to TechCrunchthe company is focused for now on the western United States, where the hot rock is closer to the surface, but does not rule out expanding to other states or abroad when its technology is even more optimized. The subsoil as a competitive advantage. While artificial intelligence is presented as the most ethereal technology of our time, its expansion depends on something deeply physical: constant, cheap and clean megawatts. In this context, Fervo represents more than just an energy startup: one more—but key—piece in the new infrastructure that supports the digital age. Google didn’t get here by chance. He has been exploring all possible avenues for some time to ensure stable power for his AI. And in that strategy of not closing any doors, while some look to the sky, others – like Fervo – look underground, kilometers underground, where the planet’s heat is beginning to emerge as one of the most solid responses.
