The waiting list for a liver transplant can be eternal, so they have created a solution: inject yourself with a miniature one

by

The National Transplant Organization of Spain makes it clear: The liver is one of the most requested organs on the transplant list, only behind the kidney. Only in the Spanish state in 2025 there were 310 people waiting and that Spain It is a world power in transplants. There are not enough donated and compatible organs to arrive in time for all those people who need them. This historical gap that no country has managed to close is a double tragedy: for the sick person, who waits without guarantees, and for the health system, which cannot offer them another way out. Liver transplant remains the only cure for certain conditions, and the path to it is full of obstacles: surgical complexity, compatibility problems, the exclusion of patients too fragile for surgery or lifelong immunosuppression. Even when an organ arrives on time, not everyone can receive it. Until now, there was no alternative. That could be about to change. The invention. An MIT research team led by Sangeeta Bhatia has developed “satellite livers”, a type of mini-livers capable of assuming the functions of the diseased liver without having to remove it. One is inside, its cells form a stable structure, connect to the person’s blood vessels and begin to produce proteins that the damaged liver can no longer make. They do not replace the entire organ, but they relieve it of its functions. They are actually small grafts of functional liver tissue that are administered via a syringe guided by ultrasound, that is, without surgery: minimal invasibility. Why is it important. Because it addresses the two big problems for those who need a liver: the shortage of available organs and those who cannot face a transplant operation. If you can have surgery, they act as a bridge until they find a suitable organ. And if you can’t, these mini livers cover the liver functions that your liver can’t do. In this way, satellite livers increase the spectrum of treatable patients. From a more general point of view, this invention is a milestone in liver tissue engineering: science has been trying to replicate the nearly 500 functions performed by the human liver for more than a decade. And if implemented in the different health systems, its impact is direct: according to the American Association for the Study of Liver Diseases (AASLD)chronic liver disease is the 12th leading cause of death in the United States and rising. Context. Although the liver is an organ with a remarkable regenerative capacity, it does not work miracles: when it exceeds a certain threshold of damage, regeneration is not enough and only the transplant remains. Since the 90s, medical science has been trying to transplant isolated hepatocytes, but the results were poor. Bhatia is not new to this either: has been there for more than 25 years investigating bioartificial liver models, which has served as a basis for understanding what conditions hepatocytes need to remain functional outside the liver. This MIT work is precisely the practical application of all this knowledge. How it works. The research team developed the idea of ​​turning these cells into an injectable along with hydrogel microspheres and fibroblasts. The spheres are intended to enable this route of administration by ensuring uniformity. Fibroblasts act as a support, helping hepatocytes survive and promoting the growth of new vessels into the tissue. Without blood supply, those cells would have their hours numbered. In the team’s experiments in mice, new vessels formed next to hepatocytes, allowing them to receive nutrients and function normally. In these rodents, the cells remained viable and secreting proteins during the eight weeks of the study. Yes, but. Although the results are tremendously promising, it is a preclinical study done in mice and the leap to humans is enormous. The human liver contains between 100,000 and 130,000 million hepatocytes and replicating a sufficient functional mass with injected cells is a challenge that this study has not yet addressed. Even assuming that we extrapolate this finding as is to humans, immunosuppressants would still need to be used. And it is not a minor problem: the fact that the immune system attacks weakened patients increases the risk of infections, tumors and kidney damage.

list of new features of the new version of Anthropic’s Artificial Intelligence model

by

Let’s tell you What’s new in Claude 4.8 Opus, the new version of Anthropic’s most advanced and powerful artificial intelligence model. This version has surprised us by arriving just 41 days after Claude Opus 4.7, and it seems that the improvements are minimal, but there is a really important change in its honesty when it comes to telling you if it doesn’t know something. In any case, here you have a complete list with all the new features that come with this new version of Claude 4.8 Opus. We are going to explain each of them briefly so that they are easy to understand. Another thing you should know is that Opus is the most advanced line of Claude models, the one indicated for more complex tasks for programming and the one that uses up your limits the fastest when you use it. There is also the most efficient Sonnet model for day-to-day tasks, which continues in version 4.6 since February 2026, and a Haiku for quick and simple questions that continues in version 4.5 since October 2025. News from Claude 4.8 Opus A more honest AI: The prominence of this new version goes to honesty. He’s significantly more honest about his own work, telling you when he’s unsure about something. It’s also about four times less likely to let bugs in code slip by without flagging them, compared to its predecessor. Performance improvements: The Agentic code score for creating code with agents increases from 64.3% to 69.2%, and multidisciplinary reasoning with tools increases from 54.7% to 57.9%. On other test benchesin the SWE-bench Verified it goes from 87.6% (Opus 4.7) to 88.6%, and in Terminal-Bench 2.1 it rises from 66.1% to 74.6%. GPT-5.5 still falls short in terminal/CLI workflows, although there have been big improvements in Claude, and both models are practically on par in web browsing and graduate-level science topics. Alignment improvements: Alignment assessments show new highs in prosocial traits such as supporting user autonomy and acting in their best interest. Rates of misaligned behavior such as cheating are lower than in Opus 4.7. Fewer hallucinations: As usual, the number of hallucinations is also reduced. Honesty when telling yourself when you don’t know something also helps reduce them. Quick mode: According to AnthropicOpus 4.8’s fast mode is now about 2.5 times faster. The company claims that the improved Quick Mode also costs three times less than before. Effort control– Users can choose between “extra” or “max” levels so that the model spends more tokens and obtains better results. Dynamic Workflows (preview for research): With this new feature, Claude can schedule work and run hundreds of subagents in parallel in a single session, being able to complete codebase-scale migrations of hundreds of thousands of lines. Available for Claude Code on Enterprise, Team and Max plans. No change in base price: The base price of API tokens is unchanged from Opus 4.7. It is 5 dollars per million input tokens, and 25 dollars per million output, with up to 90% savings with prompt caching and 50% with batch processing.

We bring you a list with Android mobile models compatible with AirDrop from Apple, so you can send files, links and everything you want from one to another wirelessly. For years, AirDrop was the technology for all Apple devices to communicate with each other and share files easily, although Android was not compatible. But this has now changedsince Google has broken down this wall and its Quick Share now allows you to share photos or documents with devices with AirDrop. And after this technological milestone, we now have the list of the first compatible mobile phones. Yes indeed, not all manufacturers have made a move yet embracing this compatibility, which means that some may be missing. Android phones compatible with AirDrop And here we go with the current list of mobile phones compatible with AirDrop. If your mobile appears on the list, you just have to activate the option Share with Apple devices in the section Quick Share of the settings Connections. Inside, click More connections and you will see the Quick Share option.

Let’s tell you What are the appliances that consume the most? in your home, so that you can keep it in mind and thus be able to use them with caution. Because we have examples like how your oven can spend about 65 refrigerators running at the same time, and they are things that are worth knowing. Of course, you should know that although they are appliances that consume a lot of power, they do it in a timely manner. They are not appliances that you will always have on, although that is precisely why it is advisable to know this consumption for those moments when we may be thinking about whether to use them or not. Appliances that consume the most at home Here you have the list made with different calculations of the Institute for Energy Diversification and Saving (IDAE)in addition to energy marketing companies such as Repsol either Naturgy. You must know that They are hourly consumption rangeswhat they consume every hour that you have them on. In addition, you should also know that the consumption range may vary depending on the appliance. Because this is the average, but then other factors such as the age of the device, its efficiency or its features can cause its consumption to vary significantly. In any case, here is the list: Ovens: between 2,000-3,000 watts Vitroceramics and induction hobs: between 1,500-6,500 watts Electric radiators: between 1,500-2,500 watts clothes irons: between 1,500-3,500 watts Electric thermoses: between 1,500-2,500 watts hair dryers: between 1,500-2,000 watts Cooking plates: between 1,500-2,000 watts Electric fryers: between 1,500-2,500 watts To give you context, a refrigerator with a high efficiency model can consume between 100 and 300 kWh per yearalthough other older or inefficient models may exceed 600kWh. Come on, they’re in something like between 30 and 90 watts per hour. Although in the long run this may cause it to consume more than others, it is advisable to take into account the consumption of other appliances that are not always on, so that you can better calculate when to use them depending on the rates you have contracted and their schedules.

We bring you the list with all the news that will come to Android 17which Google has announced in its official presentation. Almost all the focus of the news Gemini Intelligence takes itbut there are also many that are worth knowing, and that will improve the Android experience, although there is also bad news. We are going to make this text summarized so that you have a complete and easy-to-read list. We will show you one by one all the news summarizing what each one of them is about. Remember that these are the basic new features of Android 17, and that later each manufacturer will be able to implement their own. What’s new in Android 17 Gemini Intelligence: Google wants to turn its AI into a proactive agent, and it does so with this function that will arrive first on Pixel and Samsung Galaxy phones. It will allow Gemini to interact with your apps to perform complex, multi-step tasks in the background, such as organizing an itinerary or managing orders. All this without you having to do anything manually through the menus. Gemini will also integrate into Chrome to help you research, summarize information, share content, or even book appointments or parking spaces, as well as fill out more fields in apps and web pages. Task automation: Another Gemini Intelligence brick to use with food delivery apps, transportation, and more. Can you imagine being able to order your purchase online from a shopping list saved in your notes or a photograph? Well this will be possible. rambler: Another Gemini Intelligence feature, this time for the Gboard keyboard. It is a function that allows you to convert voice messages into text, being able to transcribe, eliminate repetitions, hesitations and organize sentences. AirDrop support– Quick Share becomes AirDrop compatible for everyone. This is something that the Pixel and Galaxy could already do, and now it will be expanded to everyone this year. You can make your Android phone send files to iPhone or Mac with AirDroid and vice versa. Less freedom to install APKs: Android is going to be less free, and you won’t be able to install any apps outside of the app store. Google will require developers to verify their identity so that their APK files can be installed, even if you download them from outside the app store. This is very bad news for third-party free app stores where you can install alternative apps. Pause Point: This is an option that tries to help you avoid opening apps almost automatically. Do not block access, but rather place a short pause before entering applications that you mark as distracting, such as Instagram, other social networks, or whatever you choose. Material 3 Expressive: The design language that debuted with Android 16 evolves with semi-transparency and blur effects, visible in elements such as the volume bar or the quick settings center. System icons are also improved for more cohesion with background accent colors, and more customization. WiFi and data controls: Another change is that the WiFi and mobile data controls are finally separated again in the quick settings. Custom widgets: You will be able to create custom widgets without having to design them by hand. Android will use Gemini Intelligence to build widgets for your home screen from natural language instructions. Android optimization: The Android kernel will be able to learn from the execution profiles of apps to reduce interface jerks and improve opening speed. More security: The security of the system is also reinforced, with small improvements to avoid fraudulent calls and bank scams, or detect applications that behave suspiciously. Malware detection is also improved. On-screen reactions: A wink for those who record themselves commenting on what appears on your screen. You can record a video in which what you see on your screen and your face appear at the same time with the front camera. Gaming improvements: Added support for remapping Xbox or PlayStation controller buttons. A new virtual controller function is also added that translates touches on the screen into physical signals. With this, you will be able to use controllers designed only for touch controls in your games. Universal clipboard: Finally you will be able to copy and paste content between mobile, PC and vice versa, just as Apple allows you to do it between its devices. RAM limits per app: Android will set memory caps based on device RAM. If an application tries to consume too much, Android will close it to avoid crashes and the fluidity of the operating system from being affected. OTP Security: This new security measure is added to avoid banking scams. With it, there will be a three-hour delay in accessing SMS with verification codes for third-party applications. Android Auto: Total redesign of Android Auto to completely move to the Material 3 Expressive design language. Migration from iPhone: Migration from an iPhone to Android is improved, with support for migrating messages, contacts, eSIM or the home screen. New emojis: Google has redesigned the 4,000 Android emojis to give them a slightly more three-dimensional look, with more depth and detail than the flatter, more cartoonish versions they replace. Android 17 availability Google has not specified a specific release date for Android 17. However, It is expected to arrive during next June on Pixel 6 onwards. And from there, it will be up to each manufacturer to implement it in their respective customization layers. Another thing to keep in mind is that some of the features may come later. Google has presented Android 17 as an update with many pieces, and some will have staggered rollouts. Screen reactions will arrive in summer, new emojis later, widget creation functions in summer, and others such as migration from iPhone or AirDrop compatibility later this year.

If yours is on this list, you have a problem

We are entering a reality in which passwords are going to stop being important that they have now. However, until that happens, it doesn’t cost you anything to check the passwords you have set for critical services such as your bank app or your email account, among others. Millions of people around the world they continue betting on keys such as “1234”, “123456” and the like, which any attacker can exploit in less time than it takes to write them. Below these lines we have left you a list of the most frequent ones to encourage you to take a look at one of the pillars of our digital security. We remain the same. Every year, cybersecurity company reports like NordPasswhich analyzes real data leaks extracted from security breaches and repositories of the dark webpublish the list of the most used passwords. And every year, the result is the same: predictable number sequences and keyboard combinations so obvious that it seems we haven’t learned our lesson. Spain, without leaving the norm. If we filter the data by country, the list of most used passwords in Spain is not too surprising. According to NordPass‘admin’, ‘123456’ and ‘12345678’ are the three most used passwords in Spain. In the Visual Capitalist chart that we shared with you last year, one of the most used in our country is ‘Spain’, which yes, is somewhat more resistant, but it is another one that would take a hacker a few minutes to decipher and which is still a key that no one should use. In the NordPass report, it is curious that further down the list appear passwords like ‘Nacho2006’, ‘1234ivan’ or ‘Talocha1’, which are a little more resistant, but practically as simple and vulnerable. Do you have any of these fixed?. On a global scale, the NordPass report ranks ‘123456’ as the most used password on the planet, with more than 21 million recorded uses. It is closely followed by ‘admin’, and ‘12345678’ with more than 8 million uses. Rounding out the global top 10 are ‘password’, ‘Aa123456’, ‘1234567890’, ‘Pass@123’, and ‘admin123’. According to the Basque cybersecurity center ZIUR, which works for the Provincial Council of Gipuzkoa, the ten most popular passwords in the entire world fall in seconds. Security gaps. The National Cybersecurity Institute (INCIBE) managed in 2025 a total of 122,223 cybersecurity incidents in Spain, which represents an increase of 26% compared to the previous year. Of those, nearly 46,000 were cases of online fraud, and phishing led that category with more than 25,000 cases. Why a weak password is so dangerous. The most common attacks require no ingenuity or effort. Brute force programs They try thousands of combinations per second in an automated way, always starting with the most common ones. If your password is on any list of common passwords (and there are some in the public domain), you are practically unprotected. “It is not necessary to change passwords periodically for no reason, but it is necessary to do so in case of any suspicion of compromise or after a security breach. A long and different password on each important site, saved in a manager and with double verification activated in the email and the bank, for example, protects an average user against the vast majority of common threats” counted María Penilla, director of ZIUR. What makes a password really secure. It’s not about arbitrary complexity, but about length and unpredictability. Our recommendation: that it be at least 12 characters, combining upper and lower case letters, numbers and symbols. Keep in mind that a long, random phrase is harder to decipher than a short word with a number at the end. Length protects more than complexity. That you can do if your password is on the list. Three steps in order of urgency: change it now in all the services where you use it, starting with email and your bank app. Reusing the same key on multiple sites multiplies the risk, because if your data is stolen on one platform, attackers will try that same combination on all the others. Activate two-step verification (2FA) where possible. Is the most effective measure to block unauthorized access even when someone knows your password. Use a password manager. There is no human way to memorize dozens of long and different keys without help. From Xataka we have recommended a fewsuch as NordPass, 1Password, KeePass, Bitwarden and many others. Some are paid, others are free, and others are free on one device but charge if you want to use the app on multiple devices at the same time. Change your password when there are breaches. When you suspect that someone may know it, when the service where you use it suffers a security breach, or after a long time using it on sensitive sites, the best thing you can do is change it without detours. And if you want to check if your password has been compromised on any service, you can always use tools like HaveIBeenPwned and the like.

The list of the richest in Spain has taken an unexpected turn but there is something that has not changed at all: Amancio Ortega

by

The great fortunes in Spain have been booming for five years in a row. As the global economy grapples with wars, inflation and political uncertainty, the heritage of the richest in Spain It hasn’t stopped growing. The last year was especially striking because the group of the hundred largest assets in the country increased their fortune by 14.3%, reaching an unprecedented figure: 373,450 million euros. What makes the 2026 edition of the annual list especially interesting that elaborates The Worldis that the distribution of that wealth presents notable surprises: there are names whose assets have grown stratospherically, new faces who enter the billionaires’ club for the first time, and one that has been around for decades at the top without anyone being able to displace him. Record in joint assets. The sum of the hundred largest fortunes in the country reached the impressive sum of 373,450 million euros in 2026, compared to the 326,720 million attributed to them in 2025. This implies that the group of the richest people in Spain has increased their assets by 14.3% in just 12 months. The main reason for this growth is due to the behavior of the Spanish stock market: the Ibex 35 appreciated by 50% in a single year, boosting the value of the shares of those who have its listed companies. However, the stock market boom does not fully explain this phenomenon. The companies of some of the people who appear at the top of this list are not listed, such as Mercadona or Mango, but they also had record years. Few movements at the top. The list of millionaires in Spain in 2026 does not present significant changes in the names that make it up, especially in the top positions, where Amancio Ortega, Rafael del Pino and Juan Roig lead the list easily. However, there have been some changes that do not imply a loss of assets as such, but rather respond to the fact that some fortunes have had explosive growth, while in others it has been more progressive.The most relevant movements of the year have the Puig and Daurella families as protagonists. The Puig family, driven by the listing of the cosmetic group that bears their last name and the possible integration with Estée Lauderrises to fifth place, overtaking to Sol Daurellaheir to the empire of the world’s leading Coca-Cola bottler, which is relegated to sixth place. For its part, the Entrecanales family rises from tenth to eighth place, increasing its assets by 66.93% from 5,035 million to 8,405 million euros in 2026, while the brothers Francisco and Jon Riberas Mera lose one step and remain ninth with 6,845 million, despite managing the largest industrial conglomerate with Spanish capital and have increased your assets by 1,040 million euros in the last year. More millionaires and with more millions. Within this general upward trend, the list prepared by The World It highlights that 66 of the 100 fortunes grew at a double-digit rate during the last year. The result of this acceleration is that the number of billionaires in Spain It has gone from 59 to 76 families in a single year, almost double that of a decade ago. In the same way that the volume of each of the fortunes grows, the bar for entry to the list has also become more expensive, and for enter that Top 100 millionaires In Spain, the minimum assets rise to 765 million euros, compared to the 420 million that were needed ten years ago to belong to this select group. In fact, the segment that is growing the most is precisely that of fortunes between 2,000 and 5,000 million euros, followed by the range between 1,000 and 2,000 million. That is, the second and third tranches have pulled the rest upwards, while in the tranches between 750 and 1,000 million and less than 750 million, there are now fewer millionaires than in 2024. Amancio Ortega remains immovable on the throne. Having just turned 90, Amancio Ortega continues to be the undisputed number one on the list, and with a wide distance from the second largest fortune in the country. The assets of the founder of Inditex grew by 4.9% during the last year, a rate clearly lower than that of the rest of the list, which grew by an average of 20%, accumulating some 40,000 million more euros in a single year. However, this lower percentage growth does not imply that its financial movements have been wrongit has just had more financial movement than usual. The founder of Inditex has had a very active year in the real estate field and between 2025 and 2026 he has changed the entire structure of Pontegadea, placing Luxembourg as a base of operations from which it controls all its assets in Europe, the US, Canada, and the United Kingdom. Half or more of its real estate portfolio already passes through the Grand Duchy, where it shares a fiscal neighborhood with the Del Pino family, the Álvarez Santaló, Víctor Madera or Sol Daurella, with whom it also shares a presence on the list of the greatest fortunes in Spain. The most spectacular climbs and the newcomers. Among the most striking promotions of the year, Florentino Pérez stands out, whose fortune grew by 156% thanks to ACS’s stock market peak in recent months and the company’s awards in data center construction projects. In four years, the president of Real Madrid has multiplied his assets by four and is closer than ever to the top 10 on the list. Another meteoric rise has been that of Madrid-born David Ruiz de Andrés, whose fortune increased by 214% thanks to Grenergy, a company that is leading the construction of an 11,000 MW gigabattery. in the Atacama desert. The businessman in the energy sector went from having a net worth of 580 million euros in 2025, to adding more than 1,825 million, which represents a net worth increase of 214.66% in just 12 months.

choosing the Spotify list well is essential

by

When you go running, cycling or simply going to the gym, there are some songs that seem to give us greater energy. And it is not just a subjective sensation, but science has been studying music for years as a tool that improves physical performancealthough without specific data. Now science has detailed exactly how much it can improve in numbers and, above all, where it will end up affecting. An experiment. This is something that researcher Andrew Danso has developed with the help of 29 physically active adults who performed high-intensity cycling sessions at 80% of their maximum power. But the important thing here is that the participants pedaled in two scenarios: in complete silence and listening to the music they had previously chosen with a tempo of between 120 and 140 beats per minute. The results. After being in these two situations, the research indicated that with music the cyclists lasted an average of six minutes longer than those who were completely silent, which represents an increase in resistance of 20%. Although it does not stop there, since, despite pedaling for longer, the heart rate and lactate levels (which determine how demanding the exercise was) at the end were identical to those who had been silent. This means that the feeling of effort was much less because they lasted longer with the same intensity, making the exercise sessions of much higher quality. Because? Here the question is quite clear: How is it possible to perform 20% more without the body paying for it with a higher heart rate? For science, one of the answers lies in cognitive dissociation, since music acts as a barrier that diverts attention from the signals of pain, muscle burning and fatigue that the body sends to the brain. Studies here indicate that this distraction reduces perception of effort by about 12%. But it doesn’t stop there, since by adjusting the rhythm of the exercise, such as pedaling, to the tempo of the music, the movement becomes more efficient, causing less energy to be spent to do the same work because the rhythm acts as a metronome that optimizes the cadence. The importance of the song. A crucial detail of the Finnish study is that the music was chosen by the athletes themselves, since it is not enough to put a generic ‘training music’ playlist on Spotify, but for the effect to be maximum there must be an emotional connection with the song. In addition, very calm music is not useful, but it must have a tempo in the range of 120-140 BPM so that it is a motivating rhythm and easy to synchronize with sports activity. And it is not something new, because already In the past there were studies that pointed to this improvement in performance, although now it goes a little further.

We believed that the success of artificial insemination was a genetic lottery. Turns out it depended on your shopping list.

by

When we consider having a child, the truth is that there are many factors that can intervene such as real obstaclessuch as age. This means that science is focused on looking for different variables that can be ‘altered’ to tip the balance in our favor and favor fertility. And the last one that has been known is related to the much loved Mediterranean diet. A new investigation. In a recent published study in the magazine Food & Function, A Spanish research team has come to the conclusion that it is not about eating healthily, but rather that we need a set of nutrients that the Mediterranean diet gives us, which directly modulate the ecosystem of bacteria that our body has and that prepares it for a successful pregnancy. The bacteria. On many occasions we see them as our enemies by causing very severe infections, but the reality is that they play a fundamental role within our body. In this sense, we have spoken on many occasions of the intestinal microbiota, but there are also large bacterial colonies in the vagina that protect against a large number of infectious diseases. In this sense, the research team analyzed vaginal samples from 104 women between 18 and 38 years old who had been diagnosed with primary infertility and were undergoing artificial insemination processes. What they saw here is that the success of fertility treatment depended largely on who “governed” the patients’ vaginal microbiota. The results. After crossing the samples with the patients’ diet, it was seen that those who followed a Mediterranean diet had a microbiome dominated by bacteria of the genus Lactobacillus. These microorganisms act as a protective shield and are strongly associated with a higher rate of successful pregnancies. On the contrary, a poor diet left the door open to bacteria such as Gardnerella vaginalis. This pathogen is not only linked to the annoying bacterial vaginosisbut the study directly relates it to implantation failures and failure of artificial insemination. Because? Here the Mediterranean diet stands out for the micronutrients that foods contain and that we ingest almost without realizing it when we follow this dietary pattern that is so common in our country. Here vitamins A, C, D and E, along with beta-carotene, calcium and zinc, act as protectors of the vaginal ecosystem. These elements not only nourish the patient, but selectively nourish the Lactobacillus, strengthening defenses against bacterial vaginosis and creating the perfect uterine and vaginal environment for insemination to thrive. It is becoming more and more important. Although this study details for the first time this interaction between diet, vaginal bacteria and artificial insemination, scientific literature has already been warning that the refrigerator matters a lot in fertility. But previous studies already indicated that women who followed a Mediterranean diet in the months before undergoing in vitro fertilization had success rates that were up to 68% higher. In this way, you can see that it is increasingly important to keep in mind that what you are going to eat is essential for even a new life to take shape.

a wish list with everything you need to set up a base on the moon

by

When NASA still did not know how Orion’s journey was going to go within the framework of the Artemis II mission (it left on April 1 and returned successfully ten days later), the North American space agency presented its “Ignition” project with an ambitious objective: to establish a permanent base at the lunar South Pole. He approach To achieve this, it requires spending 20 billion dollars in seven years and carrying out 81 launches. It is not only a roadmap, but also a wish list for the industry and international partners where it identifies the technological gaps that must be closed to convert one-time lunar exploration into permanent human presence. NASA’s plan. The strategy to set up a base on the moon is divided into three clear stages and is iterative: Phase 1 focuses on demonstrating that it can be reached reliably, validating the landing sites and carrying the first astronauts. The limit of four tons per trip will be reached. There are 25 launches and 21 moon landings planned. Phase 2 aims to establish initial infrastructure, manned missions every six months, and increase payload capacity to 60 tons. With 27 launches and 24 moon landings. Phase 3 already aims for continuous human presence, having the capacity to move 150 tons of cargo and prepare the lunar territory. With 29 launches and 28 moon landings. Why is it important. To begin with, because the South Pole of the moon allows access to frozen volatiles (mainly water ice) in permanently shadowed regions, which could enable the use of in-situ resources, an essential step for spatial autonomy. But although the lunar base is an achievement for humanity per se, we must not lose sight of the fact that NASA does it with another objective in mind: Mars. The moon is their testing ground. In fact, this base on the moon will be a testing laboratory for seven critical areas before establishing a human base there: nuclear reactors that operate in space, operating without constant help from Earth, understanding how long missions affect the human body, creating space supply chains, protecting against abrasive dust, avoiding contaminating other worlds, and designing systems that serve both the Moon and Mars. On the other hand, with the moon NASA intends to open a market where private industry assumes some services, reducing costs for the North American organization (and therefore, for citizens). Context. Unlike the Apollo missions, which landed in equatorial areas, there is now interest in landing and settling at the lunar south pole as it offers a unique strategic duality: craters that never see sunlight (and may have water ice) next to mountains that almost always have sunlight (for solar panels). Having access to energy and frozen volatiles scientifically, strategically and economically justifies the site selection. But working there is extremely difficult. The terrain is rugged, there are high mountains and deep craters, and there are extreme thermal and lighting challenges. The Sun remains low on the horizon, creating long shadows that make solar energy generation difficult and subject equipment to periods of extreme cold. For the astronaut team it will be hard: You will have problems seeing dangers and doing basic tasks, because the human eye does not adapt quickly between extreme light and total darkness and you will also have to access those pronounced craters for ice. What NASA needs. The document identifies functional gaps that the industry must help close, classified into six subsystems: Robotics: robots that unload and move cargo weighing hundreds of kilos, that are controlled from Earth, and that work near astronauts without danger. Communications: fast connections (over 500 Mbps) between the Moon and Earth, allowing lunar equipment to communicate with each other, and lunar GPS. Logistics: systems to connect pressurized modules and transfer water, oxygen and cargo. Housing: habitats that function from days to months, with gym and medical systems so that astronauts do not weaken, garbage management, and that survive voids between missions. Transport: small rovers to explore, large rovers (at 10 km/h) manned and autonomous, which work both in light areas and in dark craters. Energy: generate and store 5 kilowatts withstanding more than 5 days of total darkness, distribute electricity between equipment. How are they going to do it?. Essentially they will follow two strategies: Previous tests with commercial robotic missions before risking human lives. Although the technologies exist on Earth, they work differently on the Moon, so they need to fly to space to validate them for debugging. An example: from the manned flyby of Artemis II to the surface landing on the moon there will be an intermediate mission in 2027. Astronauts will test docking, life support systems and communications with commercial lunar landers from SpaceX and Blue Origin, but in low Earth orbit, where rescue is still possible. There will be interoperability. With common standards that allow systems from different providers to work together. Collaborative development of standards for power, coupling and communications will enable effective partnerships. NASA is seeking partners for nine critical areas: habitats, cargo transportation, small robots, large rovers, mapping lunar resources, sample storage, and advanced navigation. Yesyes, but. The mission is ambitious, essential for space colonization and the schedule is tight, but it also faces three main threats. For starters, basic information about the moon is still lacking. We do not know the accessibility of features of interest, such as rocks or craters, or how lunar dust behaves or something as essential as where exactly the ice is. On the other hand, politics kills space projects: according to the Planetary Society To date, they have already spent 107 billion dollars, largely due to the continuous changes in the programs carried out by the different administrations. Finally, it is worth remembering that this is a race. China and Russia also want put a nuclear base at the South Pole and whoever gets there first will decide the rules. That pressure to go against the clock can cause NASA to accelerate and make the mistake that the plan wants … Read more
