a mining camp and an enigmatic trail of green rocks

by

The high mountains have always been seen as an almost natural limit for survival due to the extreme conditions that have to be experienced, and that is why archaeologists assumed that this location was too hostile an environment for our ancestors. However, a new and surprising discovery At more than 2,200 meters of altitude, he has just blown up that idea by pointing out that not only did they go up there, but they spent many years working to search for minerals. What has been seen? A recent study Published in the journal Frontiers in Environmental Archeology, it points to the first evidence we have that there was a prehistoric human presence in the Pyrenees. Here the setting is none other than Cova 338, a rock shelter located at 2,235 meters of altitude where it has been seen that our ancestors had their work activity. Some green stones. What archaeologists have found in Cova 338 is not a simple shelter to shelter from a storm. Here it has been seen that the site houses multiple combustion structuressuch as homes or areas where fires were made to cook or simply keep warm, which indicate that the place was inhabited in a continuous and planned manner. And we know that they were from prehistory because of the carbon-14,14 that leaves no room for doubt. But the discovery that has drawn the most attention to experts are some fragments of green rock, which are said to be malachite, which is a mineral rich in copper. Because? The fact of having malachite here has made researchers think that we are facing a camp oriented towards mining prospecting and early metallurgical work. In this way, our prehistoric ancestors were combing the Pyrenean peaks in search of the necessary resources to make the first metal tools and jewelry. A child in the heights. The Cave 338 It also hides a human and deeply moving component, since among the remains of extinct fires and fragments of malachite, the research team has found human remains belonging to a child. Right now, the exact reasons why it is there or why it ended up dying are a great mystery, so it adds a layer of social complexity to the site. This shows us that expeditions to the high mountains were not exclusively composed of isolated groups of adult hunters or miners, but rather involved family dynamics or broader demographic groups. European archaeology. To date, the traditional archaeological narrative considered areas above 2,000 meters as “marginal spaces” during prehistory. Literally, true technological and social innovation was thought to occur in the lower valleys and plains where weather conditions were much more favorable. But this new study forces us to rewrite the Alpine and Pyrenean history books, since Cova 338 demonstrates that prehistoric humans had great knowledge of high mountain geology and the logistical capacity to establish stable camps, light fires at extreme temperatures and process minerals in harsh conditions.

Today the green turtles are finally out of danger

by

Halfway between South America and Africa, in the immensity of the Atlantic Ocean, a small volcanic point emerges that is the ascension island. For centuries, this piece of land was the scene of a systematic massacre, but today it represents one of the greatest success stories of marine conservation in the 21st century, culminating last October with a historic announcement that the green turtle has officially gone from being “endangered” to being classified as “least concern.” His story. To understand the magnitude of the Ascension phenomenon, you must first understand the journey since each season, thousands of green turtles They travel 2,300 kilometers from the coasts of Brazil to this remote island to spawnthat is, release their eggs. But… How do they manage to find this small island in an ocean as enormous as the Atlantic? A GPS. The famous biologist Archie Carr proposed in his day that these creatures use a kind of “olfactory GPS”, with which they were capable of find chemical fingerprints dissolved in the ocean currents that emanate from the island. Although the exact mechanics remain the subject of study, since genetic analyzes based on mitochondrial DNA leave no doubt that there are perfectly differentiated Atlantic populations and that of Ascension has a unique signature. In fact, studies indicate that turtles born in Ascensión travel throughout the American continent, representing between 43% and 47% of those captured on the coasts of Uruguay and entering the Patagonian Sea. A dark past. Since its discovery in 1501, Portuguese and British sailors saw Ascension not as a sanctuary, but as an all-you-can-eat buffet, as has been masterfully documented. in works as Ascension: The Story of a South Atlantic Island by Duff Hart-Davis. For centuries, common practices were “flipping” where sailors literally turned turtles over on the beach, immobilizing them to keep them alive with their fresh meat for months. Here there are historical testimonies such as that of chaplain John Ovington in 1691 who recounts the industrialized slaughter of these reptiles, which were sent alive to England to satisfy the demand for “turtle soup.” Something that brought the species to the brink of extinction. A turning point. It arrived in 1977, and coincides with the moment it began control and monitoring of this species on nesting beaches, reversing centuries of human impact. And the results indicate that while in 1977 3,752 nests were counted annually, today the island hosts more than 25,000 nests each year.

It has rained so much that Morocco has not looked so green for a decade

by

That the first two months of 2026 it has rained a lot It is something that we can say because we have lived it in our flesh, but its impact is such that the Earth, or rather, the portions of it where rainfall has occurred almost continuously, has also suffered a before and after. You may notice that there is more vegetation or that the river is higher, but from space it looks better: this scar in the south of the peninsula It is magnificent proof of this. The European Space Agency’s Copernicus Sentinel-3 continues to patrol the planet to record sea and land surface temperatures, sea level height and ocean color to study climate, oceans and terrestrial ecosystems. And in its sweep it has left a shocking image: the new and green Morocco. Precipitation in recent months in Morocco reached 360 millimeters at the beginning of February 2026, 54% above the average of the last 30 years and 215% more than in 2025, as reported by Swissinfothe international service of Swiss public radio and television. Torrential rains have given Morocco a respite With this rainy season, the Minister of Equipment and Water, Nizar Baraka, announced the end of a cycle of continuous seven-year drought that had wreaked havoc on agriculture and livestock. The situation was so critical that Morocco breathed a sigh of relief: the politician explained that with these rains the country was assured of up to three years of drinking water. Of course, like Spain, Morocco also suffered from floods like the one that occurred in the Loukkos basin (they reached maximum flows of almost 3200 cubic meters per second). From drought to orchard in the north of Morocco. Via: Copernicus Sentinel 3 As a picture says a thousand words, above these lines is the northeast of Morocco photographed by the Copernicus Sentinel-3 in mid-February 2025 in the middle of the drought and a year later. In 2025, the scarce vegetation was visible from space and now, after two months of intense rains, the terrain has been transformed into an expanse of green vegetation visible from space. The image on the left corresponds to February 20, 2025 and a generalized drought can be seen in practically the entire area. On the right, just a year later, you can see extensive vegetation. However, on February 20 of this year, available water resources reached 11.8 billion cubic meters, according to the data managed by the ESAwhich represents an increase of approximately 155% compared to the same period in 2025. These rains have also made it possible to fill the reservoirs, which has reached 70.7% of the total capacity of the dams. According to the Moroccan media Le Matinare figures that the North African country had not seen since 2018. Faced with this hydraulic pressure, the authorities have carried out various controlled preventive releases of water to protect the structures. But beyond ensuring its infrastructure, these rains have a direct impact on Morocco’s water economy: from consumption to the agricultural sector through hydroelectric plants.

In 2022, the gas crisis skyrocketed the price of electricity in Spain. In 2026 we have a “green shield” but also a serious problem

by

Just when in Spain we began to breathe a sigh of relief, convinced that we had overcome the inflationary trauma of 2022 “after cutting energy ties” with Russia, history repeats itself. This week a “black Monday” began that has shaken international markets. This time the epicenter is not in eastern Europe, but in the Persian Gulf, after the recent attacks that have been forced to paralyze QatarEnergy facilities. The impact on our country has been devastating. According to data collected in OMIEthe price of electricity in the wholesale market has jumped 60% in just 24 hours, climbing to 90.14 euros per megawatt hour (MWh). To put it in perspective, this represents a 1,300% increase in price compared to what we paid just a month ago. The President of the Government, Pedro Sánchez, has already warned that We must prepare for a “long war” with serious global economic consequences. And the fear is already palpable in the street with the long lines that yesterday we observed of drivers trying to fill their tank at gas stations low cost before prices continue to rise. If the gas goes up, why does the electricity go up? To understand why a conflict thousands of kilometers away makes our electricity more expensive almost instantly, you have to look at how our system works. As explained The Confidential in a very didactic way: the European electricity market is “marginalist”. This means that the most expensive technology that needs to be used to cover the demand of a specific day is the one that sets the final price of all energy. If the sun or wind is not enough and the gas plants have to be turned on, all electricity is paid for at the price of gas. And the gas, right now, is trapped in a war funnel. As we have already explained these days20% of the liquefied natural gas (LNG) and 25% of the world’s oil transit through the Strait of Hormuz (the epicenter of the current tension). Any threat of a blockade in that area generates a domino effect that triggers reference prices in Europe. The energy expert Joaquín Coronado explained in LinkedIn that this panic is already real: The prices of electricity futures for the rest of 2026 have suddenly risen by 24%. As he himself points out, “only the price of gas has changed,” but that is enough to drag down the entire system. The hit in the pocket. All this macroeconomics lands directly in the bank account of citizens. As pointed out The Countrythere are more than 11 million users in Spain who have regulated rates (the PVPC for electricity and the TUR for gas) who will notice this increase almost immediately, since their contracts reflect the daily fluctuations of the market. The calculations about what this crisis is going to cost us are already on the table: The OCU, in statements to The Newspaperestimates that if these prices are maintained, the average electricity bill with a regulated rate will jump from the 62 euros we paid in February to around 82 euros in March. An increase of 30% in a single month. A platform report Roams figures the monthly impact about 12 euros extra for electricity (17% more) and increases of up to 18% on the gas bill. The worst scenario is drawn the comparator Selectra: If the conflict drags on and we return to the panic levels of 2022, the electricity bill could skyrocket by 200%. But energy is just the first domino. Financial Times collect warnings from the chief economist of the European Central Bank (ECB), who already assumes a short-term rebound in general inflation. As oil rises, transportation rises: from fuel at the pump (gas stations already assume extra costs of 12 cents per liter) to maritime freight of goods and plane tickets, which on some routes to Asia have quadrupled in price. So, are we the same as in 2022? The good news is that we are not exactly at the same starting point as when the Ukrainian war broke out. As analyzed elDiario.esSpain today has three “mattresses” that cushion the first impact: the arrival of spring (which reduces the use of heating), some reservoirs 83% full (which allow generate a lot of hydroelectric energy cheap) and an electric mix where more than 50% of energy is already renewable. Furthermore, the PVPC formula was recently renovated so that it does not depend only on the daily market, softening the extreme peaks a little. The bad news is that we have exchanged one problem for another. To stop depending on Russia, we throw ourselves into the arms of the United States. As the economist José Carlos Díez warns in the chain Vibe Zero44% of the gas we consume today comes from the US. This places us in a position of extreme vulnerability to the new geopolitical “black swan”: the anger of Donald Trump. The refusal of the Spanish Government to give up the military bases of Rota and Morón for the offensive against Iran has caused Trump to threaten to cut off all trade with Spain. If the United States turns off the tap on LNG ships, José Carlos Díez warnsSpain does not have the physical capacity or infrastructure to replace a supplier that gives us almost half of our gas from one day to the next. The social shield and our pending duties. Faced with the threat of the crisis becoming entrenched, the Government is already moving. According to Expansion, If the conflict lasts more than four weeks, Pedro Sánchez’s Executive has on the table reactivating the “social shield” of previous crises: reductions in VAT on electricity, fuel discounts and direct aid. However, fiscal patches do not hide the underlying problems. In Xataka We have put our finger on two great absurdities of our system. On the one hand, we are an “energy island” since we have seven regasification plants capable of receiving ships from all over the world and helping Europe, but we do … Read more

The country that opted most for green now embraces the one made with gas

by

Just a couple of years ago, the atmosphere in German energy policy was one of pure euphoria. The small town of Bremervörde (Lower Saxony) had just opened the first train route operated solely on hydrogen. With an estimated saving of 4,000 tons of CO2 per year, the project was the perfect showcase for the Government’s great plan: relying the entire weight of its decarbonization on the purity of green hydrogen However, time has cooled enthusiasm and the current hydrogen landscape in Germany faces harsh economic realities. Refueling stations for hydrogen cars languish; in fact, H2 Mobility, the country’s main operator, announced the closure of several of its stations due to the lack of demand in passenger vehicles and constant supply bottlenecks. This face-to-face collision with reality has forced a drastic political turn: Germany, the country that most opted for the purity of green hydrogen, is modifying its laws to embrace “blue” hydrogen, that which is produced from natural gas using carbon capture and storage (CCS) technologies. Urgency changes the rules. The fractions of the government coalition (Union and SPD) have agreed to amend the Hydrogen Acceleration Law so that the production of blue hydrogen now enjoys the status of “overriding public interest”. Originally, this regulation sought to streamline bureaucracy only for 100% renewable projects, but the new draft expands its scope of application. As the specialized publication points out Tagesspiegel Backgroundthis change equates at the permit level the facilities that extract hydrogen from fossil gas (capturing CO2) with those that use wind or solar energy. This shift towards natural gas raises an obvious question for a country that has just gone through a severe energy crisis: where will the raw material come from now that the Russian tap is closed? The answer look north. Gas from the Barents Sea, of Nordic and Norwegian origin, is emerging as the ideal geopolitical lifeline to fuel this new European blue hydrogen machinery, guaranteeing industrial supply without falling into dependence on Moscow. A devastating wake-up call. This political shift does not come out of nowhere, but comes after a devastating report from the German Federal Court of Auditors (Bundesrechnungshof). According to this supervisory bodydespite the billions of euros injected in subsidies, the government is flagrantly failing to meet the objectives of its own strategy, as neither supply nor demand are growing as planned. Kay Scheller, president of the Court, publicly demanded a “reality check”, warning that, if it is not assumed that green hydrogen will not be competitive in price in the short term, federal finances will collapse under the weight of subsidies. The energy transition simply cannot wait for green hydrogen to be technically and economically viable on a large scale. The central problem is the cost. While natural gas (including CO2 emission rights) is between 43 and 67 euros per megawatt hour (MWh), the forecasts for imported hydrogen in 2030 rise to a range of between 137 and 318 euros per MWh. This abysmal price difference — which can reach 275 euros per MWh — makes it unfeasible for companies to make the change in the short term. Train crash. The business sector has breathed a sigh of relief. As explained in another article by Tagesspiegel Backgroundkey entities such as the Association of German Energy and Water Industries (BDEW) and the Chamber of Industry and Commerce (DIHK) had been demanding this pragmatic step for some time. They argue that the transformation of heavy industry cannot sit idly by waiting for there to be enough wind and solar farms to flood the market with green hydrogen at affordable prices. On the contrary, environmental organizations They denounce that this movement It is a serious setback that will only consolidate and perpetuate the dependence of the largest European economy on fossil fuels. To unclog the sector, the Minister of Economy, Katherina Reiche, promised a few months ago simplify procedures “from the ground up”, recognizing that current processes are too slow. The declaration of “overriding public interest” will function as an administrative fast track that will cover not only production, but vital infrastructures as maritime import terminals and Liquid Organic Hydrogen Carriers (LOHC). The risk of the “white elephant” and the fiscal hole. But legislative flexibility may not be enough to cover the enormous financial hole that is looming. The specialized portal CleanTechnica goes deeper, warning of the severe danger of “sunk costs”. Building and pressurizing pipelines without assured customers turns a theoretical infrastructure into an active spending sink. The Court of Auditors supports this thesis and warns of a serious synchronization problem: Germany has planned a huge 9,040-kilometre pipeline “core network”, but it is being built for a demand that today is a mirage. Large steel projects that were going to consume 18 TWh annually are faltering; of the four main ones, one has already been canceled and the rest face uncertain deadlines. The financing mechanism of this network is based on future users paying tolls to repay a state loan from the KfW development bank of up to 24 billion euros. If demand does not materialize and the pipelines remain empty, the mechanism will fail miserably, leaving German taxpayers exposed to losses exceeding €18 billion. The “Plan B” of the European locomotive The utopia of a Germany driven exclusively by green molecules has collided head-on with State accounting and the non-negotiable deadlines of heavy industry. Faced with the imminent risk of losing competitiveness and generating a fiscal crisis, the government has been forced to sacrifice the purity of its initial ecological ambitions. The country has understood that it needs an urgent “Plan B.” That Buxtehude train that in 2022 promised an idyllic future powered only by the wind and the sun, will have to share the track, at least for the next few decades, with the pragmatism of natural gas. At this crossroads, blue hydrogen has ceased to be the “dirty brother” and undesirable and has become the indispensable temporary lifeline of one of the great European economies.

you will never see a green star

by

There will be those who are too lazy to walk the dog at night (especially in winter) or at 6:30 in the morning, but I love finding it all asleep and being able to calmly raise my head so that, while I walk around the outskirts of my city so that my dogs can do their things, look at the sky to see what I find. One of my hobbies is, like when I was little, trying to distinguish what I find: The Polar Star, at this time of year also El Carro, the very bright Sirius with a bluish white or orange tone Aldebaranthe red Betelgeuse or the blue supergiant Rigel. Although there is light pollutionFortunately, I live near several municipalities starlight and it doesn’t take much to find authentic shows. I have seen stars of a few colors, but never green. The reality is that I look at the stars with no other instrument than my eyes and that implies only see those bright enough to emit enough light to activate the conesthe color-sensitive cells that are in the retina. But still, the stars I encounter seem white, blue, red, orange or yellow. Viewing the sky with a telescope things change and there you can see fainter stars or even go up a level and take a look (and try to interpret what space telescopes see). What is hard to see are green stars. Spoiler: it is as much a matter of the stars as it is of our eyes and their way of perceiving color. The Sun’s peak emission is green. There are several reasons why we never see it that color. A star behaves like a black bodythat is, it emits light depending on its temperature. Simply put: they emit light because they are hot. In fact, their color depends on their temperature: the coldest ones emit red light and those that are very hot glow blue. Different Planck curves for stars of classic colors: blue, yellow, red. POT However, this is a simplification: they actually emit in a wide range of colors but in different proportions in an asymmetrical bell shape (the Planck curve that you see above these lines) and it is the mixture that gives that final color. The relationship between the temperature of a star and the color where it emits the greatest amount of energy (the tip of the curve) is obtained from the Wien Displacement Law. If a star has a temperature of about 5,500K (very similar to that of the Sun), its peak emission would be precisely in that green zone. But we have never seen the sun be green. Here our eyes come into play: the color of a star is not an intrinsic property of light, but rather an interpretation of our eyes against that jumble of photons. The eyes have three types of coneseach of them sensitive to red, green or blue light respectively. That is, if an object emits or reflects red light, only the red cones would send a signal to the brain to perceive it that way. Obviously the brain can interpret more colors: the key is that these three types of cones can send the signal in different proportions and then they are mixed in the brain. Precisely what happens with the Sun, which although it emits the greatest amount of light in blue and green, simultaneously emits so much red and blue light that the combination ends up averaging in the brain as white (another thing is that is classified like a yellow dwarf star. Due to the physics of black bodies, there is no stellar temperature that excites only the green cones of the eye without also activating the red and blue cones. And since cameras imitate the vision of the eyes, the stars do not appear green in the photos either. Yes, but. After all this explanation it turns out that there are a couple of stars that some people claim to see green, but no: in reality They are brain tricks. It is the case of Almacha star system formed by a giant, bright orange star and a triple system of three blue stars so close that from our perspective they cannot be distinguished separately, but rather blend into a point of light. Our brain tries to balance orange with its complementary color, green. The result: we can perceive it as orange. Of course, the cameras do not take issue with this biological processing error. The other is Zubeneschamalia solitary star whose color we confuse either by subjective perception or by effects of the atmosphere. That doesn’t mean there aren’t green celestial objects in the sky. There are a few nebulae with a very striking green tone thanks to the intense emission of oxygen atoms, we have also seen emerald green comets (the blame lies with diatomic carbon) or planets like Earth for obvious reasons and even Uranus because of the methane in its atmosphere and how it absorbs light.

China has given the green light to buy NVIDIA chips. The problem for your companies is that you will closely monitor each operation

by

NVIDIA has hundreds of thousands of H200 chips trapped in limbo. It is one of the company’s most powerful chips and the standard of the companies that are training AI. It is preferred for train the modelsand also the weapon with which The United States sought to leave China out of the game. After movements by the two countries, The US finally approved (25% commission through) that NVIDIA could sell the H200 to Chinese companies. China has taken some time, but finally it seems that it will accept the offer reluctantly and with an ace up its sleeve: DeepSeek. The mess. The H200 issue is a soap opera. In the context of the trade and technology warthe United States played one of the best cards they had: preventing one of their most powerful products from reaching Chinese hands. They also hindered European companies like ASML from selling their most advanced machinery for making semiconductors to companies like Huawei or SMIC. China responded, of course. He attacked with rare earth -that control almost exclusively– and has been showing little by little that they can not only create advanced semiconductors on your own (and pushing old technology to the limit), but they are alive and well in the battle for artificial intelligence. Furthermore, they have developed a robotics industry and other aerospace practically out of nowhere, making a vacuum to Western chips, and that has caught the United States on the wrong foot. China makes a move. Seeing that China was advancing and the US was not getting a cent, they moved tab: They opened the door for NVIDIA to sell its H200s to certain Chinese customers. For each sale, the US took 25%, but it seems that it was something that the Chinese Big-Tech wanted to take on because they need, at least currently, that NVIDIA technology. And the GPU company itself increased production expecting two million orders above normal. The problem is that everything moved very quickly. without China, really, having said anything. Because here it is not just a question of whether the United States lets it sell, but whether China wants its companies to buy. In a tense calm that left requests halted and thousands of H200 in limbo, China has finally made a move. According to Reuters, and as we told a few days agothere are companies that will be able to place orders for the H200. There is a “but”. It is not carte blanche for anyone to place an order. According to WSJ, Chinese authorities have indicated that each purchase must be for a use considered “necessary.” That includes advanced research or development in AI. Because two factors come into play here: On the one hand, it seems that there are Chinese companies that are pressuring the Government to let them access the technology. NVIDIA was allowed to sell the H20 to Chinese customers, but if these customers can now buy the H200 – six times more capable – they want to take advantage of it. But China does not want everyone to throw themselves into the arms of NVIDIA because, precisely, they have been building their own semiconductor industry for five years with SMIC and Huawei in the lead. China’s goal is to stop depending on the US, and if everyone starts buying US chips like crazy, they will not advance on the technological roadmap that the country marked a long time ago. That is to say, it seems that Chinese regulators are going to evaluate which companies can or cannot buy the H200 depending on the use they want to give it. It has been reported that, for example, ByteDance, Alibaba and Tencent will be able to import 400,000 H200 chips. But there is a twist to all this. deepseek. China’s quintessential artificial intelligence model is one that has turned both NVIDIA and the United States upside down. The question was how it was possible that, without access to the latest technology, DeepSeek could optimize its AI so much. On the one hand, ingenuity to circumvent the CUDA standard. On the other hand, there are those who are clear that DeepSeek has been trained with NVIDIA cards… smuggled. Accusations of smuggling are nothing new in this commercial and technological war, but precisely, and according to Reutersthe company that joins NVIDIA’s massive H200 order along with ByteDance, Alibaba and Tencent is… DeepSeek. Officially, and without restrictions, they will be able to access the H200. “We have given China the argument to launch its own industry and, at the same time, we are giving them access to ours again” – Samuel Bresnick Whiplash. I really liked this concept that Wired uses to define American policy in this regard. They are the ones who started the conflict and their position has been pivoting about tariffsbut with more or less lax measures depending on the moment. It seems clear that, now, they are at a point where they have had to think “if China is going to somehow reach the technology, at least we sell it and earn something along the way.” Samuel Bresnick is a researcher at the Georgetown Center for Security and Technology and comments in Wired that the worst thing you can do is “come and go,” noting that “we have given China the argument to launch its own industry and, at the same time, we once again give them access to ours.” Get your batteries. And meanwhile, there’s Jensen Huang. The CEO of NVIDIA has taken a mass bath in recent days in both China and Taiwan, where he has met with some of the companies that move the semiconductor sector. NVIDIA sat at the same table, TSMCFoxconn or Asus, and Huang came out, half joking, half seriouswith one request: you need wafers and RAM. Regarding the purchase of the H200, China is walking on eggshells, and it makes perfect sense. It is at a point where it does not want to be left behind, and to do so it needs its … Read more

has the green light to deploy 7,500 additional satellites

by

Rarely has a technological infrastructure grown so quickly and so out of the everyday radar. While for almost everyone the sky remains as usual, thousands of Starlink satellites are already moving in low Earth orbit, building a network designed to bring connection to almost any point on the planet. In just a few years, SpaceX has gone from a first experimental launch to becoming the world’s largest satellite operator, and that buildup of hardware in space presents opportunities, but also annoyances in parts of the scientific sector. The most recent movement comes in a context of criticism from the astronomical community for the impact of these constellations on sky observation. The Federal Communications Commission (FCC) authorized SpaceX to deploy another 7,500 Starlink second-generation satellites, bringing the total authorized Gen2 satellites to 15,000. The organization not only gave the green light to this expansion, but also allowed technical improvements and a more flexible use of frequencies and coverage, in a decision that seeks to facilitate advanced mobile services and connections up to 1 gigabit per second. The authorization, in detail. The FCC has given SpaceX room to redesign and squeeze its constellation. The permit includes the update of the second generation Starlink with new form factors and advanced technology, the joint use of the Ku, Ka, V, E and W bands, and the possibility of providing both fixed and mobile services from space. Added to this is the elimination of limits that blocked beam overlap and the creation of new orbital layers between 340 and 485 kilometers, which the FCC itself presents as a way to optimize coverage and performance. In May 2019, Elon Musk announced the launch of the first batch of Starlink satellites The permit, however, does not cover everything SpaceX had requested. The company requested authorization to deploy nearly 30,000 second-generation satellites, but the regulator has decided to stay at half for now. In its resolution, the FCC emphasizes that part of these Starlink Gen2 has not yet been tested in orbit and that there remain doubts about operations at higher altitudes, above 600 kilometers, which explains why the decision on the remaining 14,988 satellites has been postponed, according to Reuters. The clock starts ticking. The FCC approval is not indefinite. SpaceX will have to prove concrete advances in the coming years, with at least half of the authorized constellation operating in their assigned orbits before December 1, 2028 and the rest before December 2031. In addition, the regulator forces the deployment of the first generation to close before November 2027, while the company prepares a reconfiguration for 2026 that will lower thousands of satellites to a lower orbit to reduce risks. Versions of Starlink satellites Expansion is not justified only by more bandwidth. Part of the constellation is intended to enable direct mobile connectivity in regions outside the United States and also strengthen coverage within the country, which would allow mobile services and data in areas without land towers at high speed. It is the same approach that already supports Starlink’s agreements with T-Mobile and with several international operators aimed at converting the satellite into an extension of the cellular network. The cost of filling the orbit. Now massive satellites are not without criticism. Astronomers They have been warning for years that constellations like Starlink generate trails in optical images and “noise” in radio telescopes, to the point that the International Astronomical Union created a specific center to protect the “dark and silent sky.” Added to this is the fear of orbital saturation and the risk of collisions, a debate that has been revived after recent incidents.

China gives the green light to the first level 3 autonomous cars. Their goal: to be leaders in 2035

by

China has given the green light to its first two passenger vehicles with capacity level 3 autonomous driving (L3). This will allow drivers to let go of the steering wheel in certain circumstances. The Ministry of Industry and Information Technology (MIIT) announced this Monday that Changan Automobile and BAIC have received authorization to manufacture electric cars with this technology, although with geographical and speed limitations. What level 3 really means. Most current driving assistance systems in smart cars are classified as L2 or L2+, which force the driver to keep their hands on the wheel at all times. Level 3, considered “hands-off” according to the criteria of the international organization SAE, allows the vehicle to assume all dynamic driving tasks under specific conditions. However, the driver must remain alert and prepared to intervene when necessary. To put ourselves in context, level 5 would represent total autonomy, without the need for human intervention under any circumstances. The restrictions of the approved models. The model from Changan, a state-owned manufacturer based in Chongqing, will be able to navigate autonomously through urban streets and traffic at a maximum speed of 50 km/h when its assistance system is activated. For its part, the BAIC model under its Arcfox brand (the Alpha S sedan) is authorized to travel on highways and expressways at up to 80 km/h. Both vehicles, which are pure electric, will only be able to operate in specific areas: the Changan Deepal SL03 will be able to do so in certain sections of Chongqing, while the Arcfox Alpha S in specific sections of highways in Beijing that connect with the airports. Why China is accelerating now. The country is treating autonomous driving as another strategic objective, just as it did when promoting its electric vehicle industry, which is so popular abroad. The authorities have set the goal of making the country a leader in the sector by 2035. According to Zhang Yongweigeneral secretary of China EV100, two out of every three new cars sold in China this year will have Level 2 or higher autonomous driving capability. “The approvals show that the authorities are willing to deregulate the market,” says Phate Zhang, founder of CnEVPost, who anticipates that “officials are likely to take a phased approach to distributing more manufacturing licenses to other manufacturers.” The industry was already prepared. According to SCMP, several premium manufacturers have been with models ready to comply with level 3 regulations for months. Geely’s Zeekr and Seres, backed by Huawei Technologies, have designed and developed intelligent vehicles considered semi-autonomous that would comply with L3 rules, according to previous announcements. Andrew Fan, CFO of Hesai Group, the world’s largest manufacturer of lidar sensors, declared reported last month that “preparations were well underway in the Chinese auto industry for the next generation of autonomous driving capabilities, even before Beijing cleared the regulatory path.” The cost of the advanced lidar sensors needed for Level 3 ranges from $500 to $1,000 per unit, with demand rising as major Chinese manufacturers accelerate development of autonomous vehicles. Where is China compared to the West. Mercedes-Benz seems to have the advantage in this area: its Level 3 Drive Pilot system was approved by German authorities at the beginning of the year to operate at speeds of up to 95 km/h on the motorway network, marking the fastest certified system for conditional autonomous driving in a production vehicle, according to the company. Tesla continues to update its Full Self Driving system, which operates at an advanced level 2. Meanwhile, manufacturers like BMW and BYD also have models in testing for Level 3 driver assistance in Chinese cities like Beijing. What’s coming now. The MIIT has confirmed which will work with other authorities to supervise these vehicles while promoting the development of this technology in China. The two manufacturers will use the models to carry out pilot programs in assigned locations. Although the ministry has not specified when they will hit the market, technically manufacturers can begin assembling the models once they receive the green light. In addition to these two state-owned manufacturers, several robotaxis companies such as Baidu’s Apollo Go, Pony AI and WeRide They are already leading the deployment of driverless vehicles worldwide, operating at level 4, which does not require a human driver.
