The liquid tree arrives that does not need soil or space

by

In some cities, trees have become a true luxury item: either because there is no space left (or there is no interest in allocating it for this purpose), because the ground is sealed by asphalt or concrete or because pollution prevents their development. This happens in large cities all over the planet, from India to southern Europe. India has released a solution that does not need rain and does not grow: it is a green water tank that does the work of ten trees. A liquid tree. Context. In cities there are two overwhelming realities: They concentrate around 70% of carbon dioxide emissions and almost half of the population lives in them. Some Spanish cities such as Madrid, Barcelona, ​​Seville or Murcia deserve special mention, among those with the lowest proportional tree cover on the continent and those with the most deaths due to the heat island effect, according to a study by specialists from the Barcelona Institute for Global Health. published in The Lancet. It is not so much a question of having many trees (Madrid, for example, has them), but of having proportional tree cover and here the Spanish state needs to improve, he says. this study of 744 European cities and the recommendations of the European Commission. Al fresco liquid tree. “Liquid trees” are, in a nutshell, urban photobioreactors. Inside there is a closed system with microalgae in aqueous solution to absorb carbon dioxide and release oxygen as if it were a real plant. Up to this point, everything is more or less as if it were a tree, but with the advantage of not needing soil, land to plant it in, or taking root. And that the cleaning function of the liquid tree is equivalent to two 10-year-old trees or 200 square meters of grass, according to the Multidisciplinary Research Institute of the University of Belgrade, to whom they came up with the concept in 2021 following the assignment of the United Nations Development Program (UNDP) to combat air pollution in the Serbian capital. The first prototype was called LIQUID 3 and was planted in Stari Grad. Why is it important. Because cities are the epicenter of the global emissions problem and if we have already seen that today a good part of the world’s population lives in cities, in 2050 it will be even worse: the UN estimates that the figure will rise to 68%. As explains Dr. Ivan Spasojevicone of the inventors of LIQUID 3, the goal is not to replace forests, but to use this system for urban areas where there is no space to plant trees. Under certain conditions of high pollution, trees suffer to survive, but according to the scientist, algae are not affected. How it works. As you can see in the image on the cover or in the video below, LIQUID 3 is a kind of aquarium with 600 liters of fresh water where there are single-celled microalgae (which we can find in any pond) continuously doing photosynthesis. The contaminated air is introduced in the form of bubbles thanks to the pumping system and a photovoltaic panel provides electricity for both the pump and the nighttime LED lighting. Furthermore, maintenance is minimal: every month and a half you have to remove the biomass generated, which serves as fertilizer (not for the liquid tree, obviously) and replace the water and minerals. They clean more than a lifelong tree. The main reason for this liquid tree compared to a traditional tree is efficiency: while parts such as the trunk, branches or roots do not photosynthesize, everything in the algae is productive. According to the UNDP Serbiathat makes them between 10 and 50 times more efficient than conventional trees. The startup Liquid Trees has quantified the CO₂ removal capacity of its liquid tree at 1.83 kg of CO₂ per kg of biomass produced. From prototype to first street trees. Liquid trees are not something new: as we have already seen, the concept dates back to 2021. However, it has not remained a mere prototype and that’s it. The technology is escalating. In 2024, the Kerala University of Fisheries and Ocean Studies and the company Lo Carbon Solutions they installed India’s first outdoor liquid tree in Kerala: a 1,000 liter tank equivalent to 10 mature trees. Almost at the same time, the DS business group and the startup Liquid Trees they planted a 1,600 liter unit equivalent to six mature trees. Yes, but. Leaving aside something obvious such as that if the electricity contribution does not come from a renewable source, the real carbon balance is worse than the figures suggest or that it is data provided by interested parties and not externally audited, a scientific review by researchers at the Kerala University of Fisheries and Ocean Studies published in the International Journal of Plant and Environment lists some limitations of the concept, among them a fairly obvious one: investment in infrastructure and maintenance is not comparable to planting lifelong trees. And that’s without talking about the environmental cost: an architectural design study from the University of Alcalá calculation that a photobioreactor façade takes more than 11 years to compensate for the CO₂ emitted during its own manufacturing. Finally, no city has yet implemented the technology at scale. What exists are prototypes and specific pilots, not deployed urban solutions.

It is capable of compressing space and time

by

15 meters deep, in a basement of Zhejiang University, China has installed a machine the size of a building capable of doing something hitherto impossible for a laboratory: reproducing in hours what nature takes centuries to build. Or destroy. Its name is CHIEF1900 and it can rotate at extreme speeds or generate a gravitational force a thousand times greater than that of the Earth, which for example serves to simulate an earthquake and its effects. Context. For a geology professional, analyzing a portion of land means deciphering the history of the planet in layers: each stratum is a record of millions of years. The problem is that nature writes it slowly. Reproducing this phenomenon in a laboratory has been one of the great challenges of experimental physics for decades. Hypergravity centrifuges are the tool that comes closest to that goal. These machines are capable of rotating at extreme speeds, generating forces hundreds or thousands of times greater than Earth’s gravity. When rotating, the arms generate outward pressure on everything inside the machine. The faster it is, the greater the force. The result is a controlled hypergravity field that compresses time and distance. What China has achieved. Zhejiang University (Hangzhou) has completed the construction of the most powerful hypergravity centrifuge in the world: it will have a total capacity of 1,900g·ton, that is, it can apply 1,900G to a one-tonne sample. The CHIEF1900 will surpass the record that China had established a few months before (September 2025), with the CHIEF1300. This power makes it possible to replicate land deformations on a kilometer scale, simulate the transport of pollutants over millennia, evaluate the resistance of a dam to an earthquake or generate thousands of new material samples. As a reference, with the CHIEF1300 they have already been able to reproduce the pressure of the seabed at a depth of 2,000 meters to evaluate the extraction of methane hydrates, or simulate how a 20-meter tsunami affects the seabed. Why is it important. To natural disasters such as earthquakes or tsunamis we have to add other consequences of human activity such as the breaking of dams, contamination of aquifers or deformation of the soil under high-speed infrastructure or the melting of glaciers. Predicting how these phenomena will behave requires information that is not available since obtaining them in real conditions is either impossible or would take decades. Dan Wilson, deputy director of the Center for Geotechnical Modeling at the University of California, explains for Popular Mechanics that this will be one of the four largest dynamic centrifuges in the world, that is, it can simulate active earthquakes using hypergravity. Chen Yunmin, chief scientist of the project, sums it up accurately: It aims to create experimental environments spanning from milliseconds to tens of thousands of years, and from the atomic to the kilometer scale. How they have done it. To build a machine with such performance, Zhejiang University brought together a multidisciplinary team that brings together personnel specialized in civil engineering, thermodynamics or automation. Among the technical challenges they faced was heat: at high rotation speeds, the centrifuge reaches such temperatures that the stability of the system is compromised. The solution was a cooling system that combines vacuum, forced ventilation and glacial coolant. The fact that the installation is buried has an explanation: it minimizes external vibrations, which could contaminate the experiments to be carried out. Pending subjects. Although the installation dates back to the end of 2025 and Popular Mechanics mentions which is already operational, no scientific results from CHIEF1900 are yet available. At an operational level, these scale models reproduce the loads well but not always all the size effects: certain material behaviors do not scale linearly under hypergravity, which requires caution in the interpretation of results. To minimize this risk, it is common for the data obtained to be compared with that of other similar facilities around the world.

The US has been looking from space for years at a huge brown ribbon in the Atlantic that goes from Mexico to Africa that should not be there

by

The blue planet looks very different from space. We have internalized things like that the Chinese Wall is seen and it is not true: what is appreciated They are the greenhouses of Almería. Or a great old man desknown as the Great Dam of Zimbabwe. And for a few years now, NASA satellites they have been registering the presence of a brown stripe that extends across the Atlantic Ocean. It’s not a big brown island or a continent, but it looks like it. What is that “brown continent”. It is a mass of brown algae that, according to research from the Harbor Branch Oceanographic Institute and Florida Atlantic University in whose last record It weighed 37.5 million tons and surpasses the 8,000 kilometers in length, more than from New York to Madrid. And it has a name: the Great Sargassum Belt. Context. He pelagic sargassum It is a seaweed that historically has always lived confined to the Sargasso Sea. However, since 2011 NASA has been documenting its expansion into the open sea until what it is now: a brown strip that by the end of 2024 left the Gulf of Mexico and spread until it reached the coasts of West Africa. This phenomenon is actually a huge accumulation of algae that reappears almost every year with one exception: 2013. The Great Atlantic Sargassum Belt is bigger than ever: evolution documented by NASA Why is it important. Because this stratospheric mass of algae is not only spectacular from a visual point of view: it has repercussions on the marine ecosystem, destroys beaches and even contributes to accelerating climate change. It is also an ecological alarm signal for the Atlantic. According to Dr. Brian Lapointelead author of the review of changes in pelagic sargassum and professor at FAU Harbor Branch, explains that it even caused the emergency shutdown of a Florida nuclear power plant in 1991. Why are they growing like foam?. Lapointe and his team have been investigating the evolution since the 1980s and have found that the nitrogen content in brown algae has increased by 55% between 1980 and 2020; the nitrogen/phosphorus ratio also increased by 50%. This change has occurred because brown algae no longer only feed on natural nutrients from the ocean, but also receive nitrogen and phosphorus from land thanks to human activity, such as agricultural runoff or wastewater discharge. The result is uncontrolled growth. Sargassum is transported by ocean currents, especially in floods from the Amazon, towards the Atlantic. There it thrives thanks to that extra supply of nutrients. An unaesthetic and harmful stain. Brown algae per se are not harmful and in fact, they serve as habitat for different species. However, its enormous presence has altered the ecosystem. Upon reaching the coasts, they begin to decompose, thus releasing hydrogen sulfide, a toxic gas that damages coral reefs, reduces the oxygen present and emits greenhouse gases. What can we do. In short: stop feeding them. After this exhaustive monitoring, the research team warns that humans should reduce nutrient runoff from the coast since, if this continues, more Great Sargassum Belts could appear throughout the ocean.

the Spanish space startup grows with Japanese money

by

PLD Space has closed a Series C round of €180 million led by Mitsubishi Electric. With this injection, the Elche company exceeds the 350 million raised in total and has a clear path to carry out the first demonstration flight of its rocket Miura 5 before the end of 2026. Why is it important. Spain has very few technology companies capable of raising this type of money on a global scale. PLD Space has not only achieved this, but has done so by attracting a top-level Japanese manufacturer that is not coming to make a financial bet but to secure access to launches for its clients in Asia. That difference between a financial investor and a strategic investor changes everything. Between the lines. Mitsubishi Electric has also signed an MOU with Lockheed Martin to collaborate on geostationary defense satellites. That the same week in which he signs that agreement he also leads this round in PLD Space is no coincidence. Japan is building a chain of access to space so as not to depend on anyone, and PLD Space fits as a provider of low orbit launches for the constellation of satellites that that ecosystem needs. For the Spanish company, this means support that goes beyond capital: it is a seal of industrial credibility. In figures: 180 million euros raised in Series C. More than 350 million in total accumulated financing. Planned capacity of 30 launches per year by the end of the decade. The Miura 5 can place up to 1,080 kg in low orbit. Target production: 4 rockets in 2026, 6 in 2027. The context. Europe has had the problem of access to space on the table for years. The delays of Ariane 6 and the dependence on American launchers have made it clear that the continent does not have a mature private alternative. He European Launcher Challengewhich calls for a test flight of a higher-capacity rocket before 2028, has acted as an accelerator for PLD’s roadmap. The company already designs the Miura Nextdesigned precisely to meet that institutional challenge. The big question. PLD Space has proven that it can raise money and that it can fly hardware. He Miura 1suborbital rocket, completed its first launch in October 2023. But the jump to orbital is different. Many launch startups have raised hundreds of millions and have not reached orbit. The real test begins when the Miura 5 takes off from Kourou, whose facilities should be ready in July. Until then, money buys time, but not guarantees.

We have been observing the snow of the northern hemisphere from space for 40 years. The conclusions of the latest major study are devastating

by

As some older people around us say: winter is already it’s not what it was. As we move forward in the decade, scientific data paints an increasingly clear and disturbing picture of the amount of snow that has accumulated in some parts of our planet. And the images seem to leave no room for doubt, since they suggest that snow coverage in the northern hemisphere is constantly reducing, altering the seasonal cycles that govern our climate. The data. The last job we have had access to was published in January of this same year, and the conclusion they have drawn is quite devastating when pointing out that 24% of the regions of the northern hemisphere show a significant decline in the presence of snow, compared to a mere 9% that has registered an increase in its amount. How it looked. To reach these conclusions, researchers have not limited themselves to looking at the thermometer. They have turned to a gigantic high-resolution database that brings together historical data since 1980 with information on both snow and ice. Mathematical model. But the real advance in this case lies in the use of advanced statistics. And, expanding on previous research from 2023, they have applied a two-state Markov chain model, which in simple terms is a mathematical model that allows analyzing the spatial and temporal probabilities of snow persisting or disappearing in specific grids on Earth over decades. That is why we are facing one of the most rigorous methodologies that currently exist to understand snow trends, eliminating the “noise” of the precipitation that is coming in the coming months. Early spring. But… Where exactly is the snow disappearing? The Markov model reveals that the decline is not uniform, but there is an alarming pattern that directly affects our side of the globe: spring melt is coming forward dramatically in Europe and Central Asia. Right now we are seeing snow melting earlier, shortening winter temperatures and directly altering the water cycle, which is vital for agriculture and ecosystems during the warmer months. The consequences. But it is not something new, since previous works already warned of this loss of snow, which is a decline that not only affects water reserves, but also the ability of the Earth’s surface to reflect solar radiation. Something that is not nonsense, since less snow means more exposed dark land, greater heat absorption and, consequently, an increase in regional temperatures. A consensus. In addition to this study, in 2025, research was also published that analyzed possible biases in climate records. NOAA historicalconfirming that the decline in snow during autumn and winter is a real phenomenon and not an erroneous measurement. But it does not stop there, since the last Arctic bulletin painted a very extreme scenario, since, although there was above-average snowfall until May 2025, the decline during June was so rapid and abrupt that snow coverage was reduced to half of what it was 60 years ago. A mixed and volatile pattern that shows a climate system under stress.

We have solved the problem of space junk by burning it. A SpaceX lithium trail just proved to be a terrible idea

by

For decades, the aerospace industry has had a consensus solution to the problem of space junk: burn it. A fairly simple phenomenon that is based on the satellite reentry when it ends its useful life in the atmosphere so that it begins to suffer friction and completely disintegrates. But the reality is that we are facing a huge problemsince physics reminds us that matter is neither created nor destroyed. We have captured him. Science is realizing that we are not removing space junk, we are just vaporizing it into metallic aerosols that are changing the chemistry of our own sky. And the definitive clue to this problem was found on the night of February 19, 2025where a team of German researchers pointed a laser into the sky over Kühlungsborn. What they detected in this case at about 100 kilometers altitude, in the thermosphere, was something that should not be there, since there were large amounts of lithium. And it wasn’t there for no reason, since it just coincided hours before with the re-entry of a SpaceX Falcon 9 rocket which had disintegrated over the Atlantic between Ireland and the United Kingdom. Something new. The signal measured in this case was not very subtle, since was 10 times bigger to the usual concentration in that region, and this finding was collected in an article because it marks a great milestone: it is the first time that the metallic contamination released from a specific piece of space junk at the exact moment of burning has been observed “live” and from Earth. The metallic iceberg. The incident with this Falcon is not something isolated in our society, but is a symptom of the structural change we are experiencing. In 2023, a team of researchers already used different devices to be able analyze more than 50,000 aerosol particles in the stratospherewhich is the layer where our ozone layer resides, at about 15-30 km altitude. What did they see? Historically, the metals found in the stratosphere came from meteorites that entered our planet. But today it is estimated that 210 tons of aluminum per year in the atmosphere comes from the disintegration of satellites and rockets, compared to the 20 tons per year that vaporize naturally from meteors. But lithium is not the only metal in the atmosphere of our planet, since scientists have detected more than twenty elements, among which aluminum, copper, lead or silver stand out… This is something that does not fit with the normal composition of meteorites, but it does coincide with the materials that different aerospace companies use to create their rockets and satellites. There is no planning. The pace of launches has skyrocketed in recent years, and if today we are close to 10,000 objects orbiting the Earth, we have to know that only Starlink aspires to have more than 40,000 satellites in Earth orbit low. But the problem is that the useful life of these devices is short, so their inevitable fate is to end up vaporized over our heads. Its effects. Science here is quite clear that the effects of filling the stratosphere with these metals are currently unknown. But the projections suggest that we should not be calm because elements such as aluminum and copper are important catabolizers that can affect the delicate ozone layer. In addition to this, metallic particles can act as special condensation nuclei, altering the microphysics of polar stratospheric clouds. And if that were not enough, adding anthropogenic material to sulfuric acid aerosols changes their size and ability to scatter sunlight. Ironically, we are altering the reflectivity of the stratosphere, the same layer that some scientists want to use for climate geoengineering, without knowing what the consequences will be. The planetary limit. The models here suggest that, if the planned megaconstellations materialize, the fraction of stratospheric particles contaminated with aluminum from satellites will rise from the current 10% to around 50%. In other words, the load of metals in the stratosphere could grow by around 40% compared to natural levels. Here for years space agencies have assumed that disintegrating satellites was a completely harmless and clean practice. The example of the Falcon 9, which has validated the warnings of the scientific community, shows us that the Earth’s orbit and our atmosphere make up a connected ecosystem. In this way, launching tens of thousands of objects into space and then burning them on our own roof may be a solution to keep space clean, but we are dirtying the sky in return.

It seemed that the Fold were the territory of Samsung and Honor. Motorola has arrived to claim its space

by

After doing what are, for me, the best folding Flip type, Motorola has just embarked on the adventure of its remaining format: the Fold. And I have already been able to try it: I was alone with the Motorola Razr Fold, I think it is a solid, versatile and high-quality bet. He is coming to cause a lot of war, I am convinced. The first thing I appreciated when holding it in my hand is that Motorola has known how to slim down the thickness of the phone so that it is almost “normal” once it is folded. The two unfolded parts are very thin: reaches 4.55 mm. Of course, only in the areas of the phone that do not correspond to the cameras, because there the thickness, as usual, is much higher. Motorola Razr Fold technical sheet motorola razr fold SCREEN 6.6 inch external Internal 8.1 inch 2K LTPO Corning Gorilla Glass Ceramic 3 outer glass DIMENSIONS AND WEIGHT 4.55mm open thickness 9.89mm closed thickness Weight: – PROCESSOR Snapdragon 8 Gen 5 RAM 16 GB RAM Boost STORAGE 512GB FRONT CAMERA 32 MP internal 20MP Outdoor REAR CAMERA 50 MP main (Sony LYTIA 828) 50 MP telephoto lens, 3x optical zoom, OIS 50 MP ultra wide angle (122 degree field of view) BATTERY 6,000 mAh 80W TurboPower Charging 50W wireless charging OPERATING SYSTEM Android CONNECTIVITY 5G OTHERS Compatible with moto pen ultra Stainless steel hinge and titanium internal plate Stereo speakers with Dolby Atmos and Sound by Bose IP47/IP48/IP49 PRICE From 1,999 euros It feels very good in the hand, as if it were not a foldable This is important, since Motorola makes no compromises: the two wings of the phone are joined together without gaps, as if from the outside it looked like a regular phone. It’s a bit difficult to put your fingers in the phone to unfold it. The movement from there offers no resistance and allows you to hold the hinge at almost any angle. The Pantone finishes, and a rough touch on the back, give it personality, as well as grip. It holds up well when folded and unfolded, just like when it comes to taking photos. I have not noticed that it is greatly offset by the weight of the triple camera. The screen looks fabulous in all conditions: Motorola has achieved extremely high brightness for both panels. The tactile response is good and the fold crease did not seem exaggerated to me. Yes, it is marked more than that of the Honor Magic V6For example. You couldn’t ask for more in terms of power: Snapdragon 8 Elite Gen 516 GB of RAM and 512 GB of storage. The test did not allow me to analyze the performance in depth. From what I tested, I highly doubt that I will have problems on a day-to-day basis, both with regular multitasking and with games. I also didn’t appreciate that it got hotter than normal. Competing to be the reference folding I don’t think he Samsung Galaxy Z Fold7 be the rival to beat for the Motorola Razr Fold: due to the extra-thin design, and the 6,000 mAh battery embedded in the phone, Moto points to Honor with its Magic V. Because that was the feeling I had when I had the new mobile: the Razr Fold reminded me of the Magic V5. When hours later I tried the Honor Magic V6I couldn’t help but draw parallels. Although the design may have certain reminiscences between one and the other, Motorola maintains software with its particular style, customizable to a large extent and with a style of Android 16 that is not too far from the Pixel. Also, very good news: The Motorola Razr Fold is guaranteed with seven years of Android updates and seven years of security updates The resistance is also certified: IP47, IP48 and IP49. It has very good quality sound certified by Bose and compatible with Dolby Atmos. A trio of reliable cameras with an AI-enhanced telephoto Cameras are usually the pending issue with folding phones, especially when they are as thin as the Motorola Razr Fold. Because there are no miracles, physics is physics. And the minimum thickness is enough for what it is, compromises have to be made. Motorola has decided to sacrifice as little as possible. Its triple rear camera debuts a Sony Lytia 828 50 megapixel which seems to behave at a good level. I was taking photos in the testing room, with plenty of light coming in through the windows, and I saw the camera resolute, accurate in colors and with well-applied automatic HDR. The wide angle is also 50 megapixels. Same as the telephoto: Motorola has relied on a trio that produces the same dimensions in the resulting images. With Quad Binning processing at 12.6 megapixels. The telephoto reaches 100x in its maximum hybrid mode, a distance that usually results in a glob. Although I have appreciated great work from the AI: can reconstruct images until you get something drinkable. It won’t be the best photo in the world, but at least it will serve to show it. With the logical risks of parts invented (or recreated) by AI. Motorola rounds off the great work it already did in the Flip format The Motorola Razr Fold is a mobile phone that surprises in the hand due to its lightness and everything it keeps inside. Power, performance, flexibility, very good cameras and the ability to become a very good work tool. At this point I especially like your desktop modeI believe that Motorola has a great asset to enhance productivity in all environments. Especially those of us who travel almost with nothing on. Very good balance between quality, performance and design. Now, it is not a phone that is unique on the market either: the Fold-type folding format is already very mature. And they are all placing themselves in a high price segment, that segment for which They seek to distinguish themselves by appearance rather than … Read more

Mars was the great space battleground between China and the US. Now it’s the Moon (and the stakes are too high)

by

For years, Mars has been the great horizon of space exploration: the inevitable destination to which, sooner rather than later, humanity had to head. Earlier this year, Elon Musk, one of the main drivers of that narrative, assured that The United States could land on the red planet within a period of between five and ten years. In parallel, in China, different voices from its aerospace sector They located the first manned mission Mars around 2033. The message was clear: the race for Mars was already underway. On paper, deadlines are as stimulating as they are challenging. Because sending humans to Mars is not a simple evolution of what has already been achieved, but rather a leap in scale. NASA itself has detailed the enormous technical complexity involved in a mission of this type: from entry, descent and landing systems capable of landing heavy loads in an extremely tenuous atmosphere, to infrastructure that guarantees energy, communications and life support during prolonged stays. Depositing a one-ton rover is not the same as lowering dozens of tons of habitable modules and critical equipment. The race no longer looks at Mars, it looks at the lunar south pole However, while Mars made headlines, the real strategy has been taking another direction. As the NASA Artemis Program and the Chinese Lunar Exploration Program have consolidated calendars, investments and technological milestones, the focus has shifted to a more immediate and pragmatic objective: the Moon. Everything seems to indicate that It’s not about giving up Marsbut to assume that the most sensible path goes through intermediate stages. In both cases, the satellite is emerging as a technological test bed, logistics platform and operational experience before facing a journey of months and millions of kilometers. The new space race, therefore, is not being fought, at least for the moment, at tens of millions of kilometers, but at a few 400,000 kilometers away. This proximity changes the equation: it reduces transit times, facilitates the shipment of supplies and allows us to react to unforeseen events with reasonable margins. But, above all, it opens the door to something that is beginning to take shape: the birth of a lunar economy. Permanent bases, scientific experiments, transportation contracts and infrastructure development could make the Moon not only a destination, but a key node of human expansion in space. The epicenter of this new phase is not just any place, but the environment of the Shackleton craterat the lunar south pole. A permanent darkness, as we can see in the photo that accompanies this article, has fueled the hypothesis that in its shadow areas it could keep water ice. This possibility explains why both the United States and China are targeting this region in their next landings, with the stated objective of studying and, eventually, taking advantage of these resources. In practical terms, we talk about water for consumption, generation of oxygen and production of hydrogen and oxygen as a propellant, whenever technology and economic viability allow it. Illuminated rim and shadowed interior of Shackleton Crater The question, then, is not just what is at the south pole, but what changes if those resources are confirmed as usable. In this scenario, the Moon would cease to be solely a scientific destination and would become a functional piece within space architecture. We are not yet talking about industrial exploitation, but about something more basic: reducing absolute dependence on the Earth in each mission. This nuance introduces a real economic dimension to the lunar race, because it alters the logic of costs, transportation and planning of future operations. This is where the notion of an Earth-Moon supply chain stops sounding futuristic and starts to fit into concrete timetables. Although the lunar economy, with its own supply chainmay seem like a distant concept, its foundations are beginning to be built. On the American side, that architecture is beginning to take shape with very specific missions. Firefly Aerospace launched its Blue Ghost 1 module on January 15integrated into the initiative NASA Commercial Lunar Payload Services. This is a mission that aims to demonstrate what a cargo delivery system would look like for our satellite when it lands on the moon on March 2. In parallel to these cargo missions, Blue Origin is preparing its own movement towards the lunar south pole. The company founded by Jeff Bezos is working on the first demonstration flight of its cargo module Blue Moon Mark 1known as MK1, scheduled for early 2026. The eight-meter-high lander will take off aboard the rocket New Glenn and will need to validate key systems before any more ambitious operations. It should be noted that the mission does not involve resource extraction, but it is a necessary step to operate in the environment where expectations about the ice are concentrated. Render of a multidome base under construction on the Moon The good news is that the MK1 has been tested at NASA’s Johnson Space Center, including thermal vacuum chamber simulations to replicate the extreme conditions of space and the lunar surface. If it passes this phase and the final integration with the launcher, the ship could become a relevant asset for future missions to the south pole. Another important fact is that the US agency you have already selected this module for transport the VIPER rover in 2027whose task will be to search for volatiles such as water ice in permanently shadowed regions. On the Chinese side, the centerpiece is the mission Chang’e 7conceived as a more complex deployment than a simple lander. The mission is targeting August aboard a Long March 5 rocket and will include an orbiter, a lander, a rover and a small jump probe. The set aims to operate in the vicinity of the lunar south pole, where experiments aimed at studying the surface and searching for signs of ice in permanently shadowed regions will be concentrated. Render of Blue Origin’s Blue Moon Mark 1 lander and VIPER If the schedule holds, China could make these measurements before the American … Read more

Two Spanish space giants have joined forces to take 5G defense satellites into space: PLD Space and Sateliot

by

Two Spanish companies they have sealed an agreement to launch new generation satellites without depending on any other foreign company. In Europe we have been with the run run of technological sovereignty. This agreement is a perfect example of this, and also a milestone for Spain if the project ends up materializing. The agreement. PLD Space, manufacturer of the Miura 5 rocket based in Elche, and Sateliot, a telecommunications satellite operator based in Barcelona, ​​have signed a contract to launch two satellites from Sateliot’s Tritó constellation aboard the Miura 5. The launch is scheduled for the last quarter of 2027, expectedly on the fourth commercial flight of the Elche rocket, and will do so from the Kourou Space Port, in French Guiana. Each satellite weighs about 160 kilos and will be launched on a dedicated mission, without sharing space with other operators. Why is it important? This agreement is presented as the first entirely Spanish private space mission, with satellites designed, manufactured and operated in the country, launched using a rocket also of Spanish origin. And the interesting thing about the project is that it would cover the entire value chain of the sector (manufacturing, launch, operations and commercial exploitation) without foreign intermediaries. Although the European Union has been trying for years reduce your dependence on operators like SpaceXthis alliance fits directly into this context. What are Tritó satellites? The Tritó constellation is a significant evolution of the current satellites that Sateliot has, weighing 15 kg and dedicated exclusively to the Internet of Things (IoT). In this case, the new Tritó have greater capacity and will combine IoT connectivity with direct device-satellite communication (D2D), including data, voice and video through 5G. Marco Guadalupi, CTO of Sateliot, counted to El Español that one of its key points is that they will be able to “establish the connection when the device is in the pocket”, being key for emergencies, natural disasters and defense applications. The risk they assume. Guadalupi does not hide that it is “a risky mission.” The Miura 5 is a new rocket, whose first launch test is scheduled for the end of this year, and its reliability has yet to be demonstrated in real flight. “We are crazy and we know what we want,” I was joking Guadalupi himself in the interview with the media. The Sateliot team claims to have visited the PLD Space integration and testing facilities on three occasions before signing. In exchange for the risk, they get something that few options on the market offer: a dedicated mission, without competing for space, and the flexibility to adapt flight conditions to their specific needs. Review. Last November, PLD Space closed financing of 169 million euros through ESA’s European Launcher Challenge, backed almost entirely by Spain, for launch contracts and improvements to the Miura 5. Sateliot, for its part, has plans to deploy up to 100 satellites in 2028 and aims to reach revenues of 1 billion euros in 2030, according to they count from Reuters. Among its shareholders is Indra, with 4% of the capital. The agreement with PLD Space also occurs while Sateliot is opening market in India. Jaume Sanpera, CEO of the company, traveled to the Asian country coinciding with the announcement, where the company already has headquarters and sees potential for a future business in which they offer connectivity in remote areas. What’s coming Before the satellites board the Miura 5, Sateliot plans to launch a prototype of the Tritó platform in mid-2027 to validate the payload. The more capable commercial satellites would be integrated into the rocket in the final stretch of that same year. Regarding the total number of satellites they hope to put into orbit, Guadalupi counted that “there will be hundreds.” Sateliot’s intention is to centralize launches to simplify logistics, and although they do not rule out other suppliers, they aim to continue working with PLD Space.

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

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.
