Four astronauts are going to undertake an unprecedented journey to the Moon. They have no intention of stepping on it

After years of delays and rumors, NASA confirmed it finally: Artemis 2 will take off towards the moon imminently: it will be on February 6 when the team of astronauts formed by Christina Koch, Reid Wiseman, Victor Glover and Jeremy Hansen returns to lunar orbit after almost 60 years. More specifically, it was in ’72 with Apollo 17. There is nothing left in the countdown for a 10-day mission full of doubts and some controversy. The previous steps. On January 17, NASA began the deployment of the enormous SLS rocket (Space Launch System) and the Orion capsule from the vehicle assembly building to launch pad 39B at the Kennedy Space Center in a 6.4 kilometer journey carried out on a gigantic Crawler-Transporter 2 tractor in enormous logistics. Now that you are on the platform, the next step is the “Wet Dress Rehearsal” (something like the general rehearsal) where the cryogenic propellants are loaded to check that there are no leaks and a complete countdown is executed that stops just before ignition to validate the flight software and the synchronization of the ground systems. If all goes well, the launch window opens on the aforementioned February 6. The crew. POT The mission. Artemis II will not land on the Moon, but will instead perform a lunar flyby with the aim of testing the life support systems and manual maneuvering capabilities of the Orion capsule in the deep space radiation environment. In addition, the spacecraft will use lunar gravity to “propel” its return to Earth without major engine ignitions. The parallels with Apollo 8. Analogies with the veteran ’68 mission are inevitable since Artemis II will not land on the moon, but will instead perform a lunar flyby. On that mission, the astronauts were able to see and photograph the far side of the moon and now, the team will travel beyond its far side. Apollo 8 was launched at a time when the program’s lunar module was not yet ready for manned flight and with Artemis II more of the same. Thus, the first planned lunar flight of Artemis is called Starship HLS (Human Landing System), it is being developed by Space However, given the doubts regarding its development schedule, NASA has a plan B: hire another company. Why don’t you go to step on the moon?. In short, because it is not a lunar module and therefore, because it is not prepared for such a purpose. NASA Deputy Director of Mission Analysis and Evaluations Patty Casas Horn deepen: “Throughout NASA’s history, everything we do carries some risk, so we want to make sure that risk is sensible and only accept as much risk as is necessary, within reason. So we develop a capability, then we test it, then we develop a capability, then we test it. And we’ll land on the Moon, but Artemis II is really focused on the crew.” The program’s debut was Artemis I, which on a 25-day uncrewed mission orbited the moon in 2022. Now we are in the next phase: the first time there will be people aboard the Artemis spacecraft. The crew will transfer to the Orion capsule to move around the moon just before the SLS rocket launches Orion into Earth orbit. Horn explains that in this mission “we will test many new capabilities that we did not have available in Artemis I”, for example the comfort of people or collateral effects such as the humidity they add to the air, their needs for food, bathrooms or water. Wet Dress Rehearsal. POT What makes it unique. The crew intends to travel beyond the far side of the Moon, which could open the doors to a new record for the distance that humanity has traveled from Earth, a title that to this day boasts Apollo 13 with 401,000 kilometers. On the other hand, the SLS is the most powerful rocket in operational configuration, surpassing the mythical rocket in thrust. Saturn V of the 60s. Logically, it will also do so with cutting-edge technology, such as autonomous optical navigation systems or the Orion heat shield, redesigned after data from Artemis I, to protect the crew during re-entry at 40,000 km/h. Furthermore, in this mission NASA has remembered diversity to mark a milestone in the form of a trip beyond low Earth orbit for a woman, a Canadian and an African American because yes, there is life beyond the white American male cishetero In Xataka | It is now possible to book a hotel stay on the Moon for $250,000.

Seoul has released a “holographic police” that arises every night in a park. The intention is clear: dissuade crimes

A park in Seoul transforms every night into an unexpected stage. From seven in the afternoon, between street lamps and shadows, the figure of a police with impeccable uniform arises. Speak in a firm voice, throw a message and, suddenly, fades in the air. Two minutes later, it reappears to repeat the same scene. It is not a flesh and bone agent, but about Un real size hologram which has become the new attraction and security measure of the neighborhood. The bet began in October 2024 as an experiment of the Jungbu police station and the Seoul City Council. The selected park was not accidental: located next to the popular gastronomic area of ​​Euljiro, it was the usual scenario of incidents linked to alcohol consumption, As the local newspaper The Scoop explains. Police were looking for a way to strengthen security without displaying more personnel in difficult coverage. Thus collaboration with a technology company arose, which designed a system capable of projecting a virtual agent every night to remember that the place was monitored. A HOLOGRAM AGAINST CRIME The device uses a projector that launches the image of a policeman on a real -size acrylic plate. Every night, the hologram appears for a few seconds and repeats again every two minutes. Its presence is not limited to the visual, since in a clear voice it always conveys the same notice, which Remember passersby permanent surveillance of the area: “Hello, we are the Jungbu police station in Seoul. This area has an intelligent CCTV system. This system is in operation so that the police can respond in real time if an incident of violence or other emergency situation occurs. The Jungbu police station will continue working with the district to create a safer community. Thank you.” The first data collected shows that the bet has not gone unnoticed. According to figures from the Jungbu police station, between October 2024 and May 2025, incidents registered in the Park were reduced around 22% compared to the same period of the previous year. The descent was noticed above all in situations of spontaneous origin, such as altercations or discussions linked to alcohol consumption. For the police, this initial effect demonstrates that the hologram has served to cover holes in the usual surveillance. Those responsible for the project insist that the idea was born from a very specific need. Agent Kim Hyun-Don, from the Jungbu police station, He explained in an interview with the South Klab Canal that the park was surrounded by bars and leisure premises and that many neighbors preferred to avoid it at night for fear of meeting drunken people. “We thought that a visible policeman, even if it was virtual, could give security to citizens and at the same time deter those who could cause problems,” he said. For the police, the hologram is a risky experiment, but also an opportunity to innovate in prevention. Not all citizens interpret the hologram in the same way. While some perceive it as a presence that provides security, others believe that the measure will lose efficacy over time. A neighbor interviewed by The Scoop warned that “to really reduce incidents Frequent patrols are needed or a change in the dynamics of the neighborhood. ”In parallel, comments on the Internet oscillated between the joke and surprise: several users described it as a“ police ghost ”, although others celebrated the originality of the experiment. Seoul Metropolitan Police The project, despite its good initial results, is not free of problems. Those responsible admit that technology is sensitive to external factors: on extreme heat or intense cold days, The projector can fail. There are also neighbors who complain that the voice of the hologram is not heard well when there is noise in the street. To this is added a deeper doubt: if at the beginning it impresses and deter, over time it could become part of the landscape and lose its impact. Seoul’s “holographic police” has become a striking experiment within the debate on how to strengthen security in public spaces. Its initial efficacy shows that technology can provide creative solutions, although doubts about their permanence remain open. It remains to be seen if this model will consolidate as a stable tool or if it will remain an anecdote in the urban history of the city.

Nvidia says that China has the best open source AI in the world. These praises have a very clear intention

Jensen Huang, the co -founder and general director of Nvidia, is in China. At the end of last week He met with Donald Trump with the purpose of defending the interests of his company before an administration that has drastically restricted your business In the country led by Xi Jinping. During the last fiscal year, which expired on January 26, 2025, China represented approximately 13% of total income of Nvidia with a figure of about 17,000 million dollars. In practice, this Asian nation is the third best client of this company only behind the US and Taiwan. The decisions made by Jensen Huang during the last months clearly reflect that he is determined to defend your presence in this market. And he is doing it. A few hours ago he has made a statement during his visit to the International Exhibition of the China Supply Chain, in Beijing, which is worth not overlooking. Jensen Huang does not give stitch without thread “The models of artificial intelligence (AI) Open source of Deepseek, Qwen and Kimi are the best reasoning models in the world today. They are very advanced. ” Huang has pronounced These words during a talk with Wang Jian, the founder of Alibaba Cloud, the AI and cloud computing unit of this gigantic Chinese company. And this statement has not arrived at any time. Whether or not, objectively, the three models mentioned by this Executive are very competitive, as the reports of Demodazzle either Mediumamong others. The really interesting thing is that Jensen Huang has praised these Chinese models at a very delicate time for Nvidia. At a time when You need to strengthen your complicity with Chinese companies to which they have been selling their GPU for several years. Last week Jensen Huang got a promise from Donald Trump: Nvidia can sell again Your H20 GPU To his Chinese clients very soon. The reception that this chip initially received was very good even though its capacities are clearly lower than those of the other proposals for this company. Jensen Huang has praised these Chinese models at a very delicate time for Nvidia. At a time when you need to strengthen your complicity In fact, initially the Department of Commerce allowed its sale in China because this integrated circuit met the restrictions it had imposed. And despite its limitations Their sales grew by 50% quarter to quarter since it arrived in this market in mid -2024. Everything was complicated for Nvidia in the middle of last April. And is that the US Department of Commerce imposed new restrictions To the export of the H20 GPU, which in practice caused this chip to stop reaching the Chinese clients of this company. During the next few weeks this GPU will come back to the facilities of Tencent, Alibaba or Bytedance, among other Chinese companies, but Nvidia will have it more difficult than ever. And is that Huawei, his main Chinese competitor, is being reinforced with great intensity. Only one day after the US Department of Commerce formalized its latest sanctions He presented his GPU Ascend 920a chip for AI that is clearly intended to occupy in the Chinese market the gaps left by the NVIDIA H20 GPU. The GPU Ascend 920 will begin to be manufactured on a large scale during the second half of 2025 using 6 Nm integration technology that have presumably developed side with Huawei elbow and SMIC. The characteristics of this lithographic node have not yet been officially confirmed, but it will probably use the technique known as Multiple patterningwhich is the same one that SMIC is using 7 Nm chips. In addition, the GPU Ascend 920 will reach a 4 TB/s transfer speed for the memory subsystem thanks to the use of HBM3 chips.

Congress has shown its intention to extend its useful life

The Congress of Deputies has approved This Tuesday a non -law proposition (NLP) on the extension of the useful life of the Nuclear power plants in Spain. The initiative, presented by the Popular Party, has come forward with 171 votes in favor (of the 349 cast), thanks to the support of Vox and a UPN deputy, in addition to the abstention of Junts and ERC. Of course, being a non -binding figure, its approval does not entail any change in the formalized closing calendar six years ago, but it does reflect the position of the chamber and summons the government to assess possible measures in that direction. No change in the nuclear blackout. The Government marked the course of the future energy policy in 2019, when it agreed with the National Radioactive Waste (Enresa), Iberdrola, Endesa, Naturgy and EDP company, the stepped closure of the five nuclear power plants in the country. It is expected that dismantling tasks will begin in 2027 and extend until 2035, with some facilities ceasing to produce electricity before others. To do this, several measures are being launched in parallel, such as the development of a radioactive waste cemetery and a portable laboratory for transfer. Nuclear remains a significant energy source. According to the Nuclear Forumwith electricity data, nuclear plants generated 19.57% of electricity in Spain in 2024. It was not only the technology with the highest number of hours of operation at full power (83.27% of the total hours) , but also the second most important production source in the country, only behind wind. At present, government plans go through renewable energies, But some actors believe that this bet will result in a less robust and stable electrical system than the current one. Nuclear centrals from Spain Europe attends the “rebirth” of nuclear. While Spain keeps firm its nuclear closure calendar, in much of Europe the trend is the opposite. A clear example is Francewhich a decade ago planned to reduce its dependence on atomic energy, but in 2022 it changed course. Not only did he abandon that idea, but decided to bet on new reactors. Finland, Slovakia, Poland, Czech Republic and Hungary They have also announced or are considering the construction of new nuclear plants. The reasons for doing them are many, but one of them is artificial intelligence (AI). AI and Nuclear Energy. Data centers that train next -generation language models require huge amounts of energy. These avant -garde infrastructures operate with the most advanced processing units of companies such as NVIDIA, which triggers their electric demand. Given the need for an abundant and stable supply, technological giants have begun to close agreements to directly access nuclear energy. Microsoft, Google, Oracle and other companies have already taken steps in that direction. And some governments, such as the American and French, are supporting these initiatives. The United States has given green light to the use of federal lands for the construction of data centers and seeks to expedite both permits and access to nuclear energy. Meanwhile, France advances strongly to become a key actor in the sector. Not only is it promoting “the largest campus in Europe” With investment of United Arab Emiratesbut also promotes a data center of more than 1 power gigavatio In collaboration with Fluidstack. “Electricity is available, you just have to connect”, Emmanuel Macron said this week. A small victory, although without concrete changes. As we have seen above, the non -law proposition has come forward with the support of Junts and ERC, Catalan parties in whose region are the nuclear power plants of Ascó I, Ascó II and Vandellós II. These facilities generate 60% of the electricity consumed in Catalonia, which underlines the relevance of the debate. However, beyond reflecting a political position and reviving the discussion about the future of nuclear energy in Spain, the measure does not alter the planned closing calendar. Today, the official plan continues its course and there is no indications that it will be modified.

Goal approaches 100,000 million invested in metoverso, and has no intention of raising the foot of the accelerator

More than ten years have passed since Mark Zuckerberg announced the purchase of Oculus And he began to profile his idea of ​​’Metaverso‘, although the concept did not gain prominence until 2021, When Facebook, Inc. was called Platforms goal, Inc. Reality labs, the division that promotes this initiative, is on the way to burn 100,000 million dollarsand everything indicates that there is still a long way before those promises of incredible virtual worlds, where to work, play and socialize, come true. Virtual and mixed reality glasses, such as Quest Pro goal, Quest 3 goal either Apple Vision Prothey are the entrance door to this type of experience. However, these devices are not yet powerful, light and affordable to gain ground in the general public. A reflection of this reality is Tim Cook’s statements last year, when Apple’s CEO recognized that their glasses are “an early adoption product” intended for “people who want to have tomorrow’s technology.” Goal continues to burn money in metaverso Between 2014 and 2024, Meta has invested more than 80,000 million dollars in its virtual and augmented reality ambitions. The data comes from your financial ones that reflect an expense of 19,875 million dollars and a benefit of 2,146 million dollars to throughout the last year. In other words, the reality Labs division closed 2024 with losses of 17,729 million dollars. Far from lifting the accelerator’s foot, the giant of social networks remains convinced that this is the way, so he anticipates a 2025 with more investment and more losses in reality labs. Few companies in the world can afford with such long term. Meta, of course, is one of them: in 2024 he recorded net profits of 87,109 million dollars in family of apps (FOA), the segment that encompasses products and services such as Facebook, Instagram, Messenger and WhatsApp. Although reality labs is closely linked to metoverso, its reach goes much further. Immediately, this division is the epicenter of commercial products with relative successlike the family of target quest glasses and Ray-Ban Metadeveloped in collaboration with Essiloruxotic. But it is also the laboratory where the future of the company is being built. Last year we first saw Oriona prototype of augmented reality glasses that, According to Zuckerberg himselfit could one day replace the smartphone as we know it. At first glance, Orion glasses are more bulky and robust than the finish lines, probably due to the internal components necessary to project images. And they integrate micro LED projectorscapable of superimposing information in the real world. The idea is to use the physical environment as a canvas for 2D and 3D apps. But there is more. Reality labs is working on the powerful, light and affordable glasses that we mentioned at the beginning. And that, of course, requires a lot of work. At the visualization level, the objective is to achieve a practically indistinguishable experience of reality. But it is not enough with high resolution screens in next -generation glasses, but it is necessary develop technologies that still do not exist to adapt to the complex human visual system. In addition, projects include the exploration of new interfaces, such as electromiography based, which allow controlling devices through neuromuscular signals. As the company itself recognizes, its bet is to develop products that we will not see soon, but will reach its maximum splendor “in the next decade” It will be necessary to see if this goal is still standing with the advance of artificial intelligence (AI), a field in which Meta is investing billions and that, at some point, converges with its vision of metavers.
