NASA has revealed why no astronaut has left the Earth’s atmosphere. Not even when they went to the moon

May 12, 2025 by usatoday24

From time to time, NASA reminds us with some anecdote or study that things are never how they seem or, failing that, that can always be questionable or have more than one answer. Recently they gave us such a simple explanation about our inability to find extraterrestrial signs that scared. They also clarified why We hadn’t returned To the moon before. The latest: remember that, technically, no human has ever left the earth’s atmosphere. And yes, I don’t even want when we went to the moon. A technically true provocation. To say that no astronaut in history has ever left the earth’s atmosphere may sound to a joke or little less than a conspiracy theory, but, from a scientific perspective and following what atmospheric models say, it is more than us A correct statement. To place ourselves in perspective and following this line of explanation, even iconic figures Like Yuri Gagarin either Neil Armstrongor contemporary space travelers Like William Shatnerhave remained, in physical terms, within the most extreme (although diffuse) limits of the Earth’s atmosphere. The key lies in how the end of that atmosphere is defined: a more complex and expansive issue of what is commonly believed. The atmosphere does not end where we imagine. All this reasoned recently Doug RowlandNASA heliophysics expert. Contrary to the popular idea that the atmosphere ends in a finite layer that dissipates before reaching the terrestrial orbit, the reality is that the atmosphere does not have a clearly defined “roof”. On the contrary, it becomes progressively more dim, but continues to spread. As Rowland toldeven hundreds of kilometers on the surface, where the International Space Station (EEI) orbits, there is still a sufficient air density to gradually stop the station. In fact, if it were not periodically driven with rockets, the EEI would end up falling by atmospheric drag. The artificial border: Kárman. For practical reasons (such as spatial treaties or legal definitions) an international convention has been adopted: The karm linelocated 100 kilometers above sea level, which marks the point where the space begins theoretically. This line serves as a technical threshold, since 99,99997% of atmospheric mass terrestrial is below. Said that, and how Explain the space agency itselfthis definition is useful for regulations and classifications, not so much to describe with physical precision the real limits of the atmosphere. The geocorone: atmosphere that reaches the moon. In 2019, A study based on data from Soho Solar Observatory (NASA/ESA), revealed that the exosphere of the Earth (specifically, a diffuse cloud of known hydrogen atoms Like geocorone) extends to about 629,000 kilometers, that is, beyond the orbit of the moon. What happens? That on that limit there are still about 0.2 hydrogen atoms per cubic centimeter. That means that, technically, even the Apollo missions that alunizarized in the 60s and 70s did not abandon the earth’s atmosphere. “The moon flies through the Earth’s atmosphere,” Igor Baliukin came to saymain author of the study, referring to the unsuspected magnitude of this invisible layer. The sun also contains us. The thing is even more complicated when both the Earth and the Moon are Inside the solar atmosphere. This extends to the edge of the helosphere, the limit beyond which the interstellar space begins. At this point it must be remembered that between the atmosphere of the earth and that of the sun there is no emptiness, but a structure of progressive and overlapping layers that contain particles, energy and electromagnetic dynamics. Therefore, and seen thus, the concept of “being in space” is less a matter of abrupt border and more a matter of progressive gradient. So where the space begins? As Rowland explainedthe answer depends on the point of view. If you ask where the atmosphere ends in a practical sense, probably about 400 kilometers, where air density ceases to have significant effect on objects. But from a more rigorous scientific perspective, that atmosphere does not disappear: it only dissipates and dilutes to barely measurable extremes, without disappearing at all. Therefore, “exterior space” is not an empty place, but a continuous environment full of particles, fields and subtle structures. In that sense, all space trips made by humans have elapsed within that extended wrapping that is still part of the planet that launched them.

After the blackout, the government defended the nuclear closure because “in Spain there is no uranium.” Reality is more complicated

May 12, 2025 by usatoday24

The question of uranium has returned to the forefront after the president of the Government affirm that “in Spain there is no uranium and therefore we will have to import it.” Although Spain has large uranium deposits, reality is always more complicated than the usual black or white policy. The second European country with more uranium. Spain has between 25,000 and 30,000 tons of uranium, “the second most important reserves of the European Union,” According to the geologist Jesús Martínez Frías. Both the ‘Red Book’ of the Nuclear Energy Agency (NEA) as the National Geographic Institute (IGN) indicate the existence of resources with the possibility of exploitation in Spanish territory, mainly in the province of Salamanca. Why they stopped exploding. Spain had uranium mining, but The last mine closed in 2000 for the “exhaustion of economically exploitable mining resources”, according to the Ministry for Ecological Transition. The Spanish Nuclear Society (SNE) said that production costs had exceeded 30% market prices, which made its continuity unfeasible. Two decades later, the Law 7/2021 of climate change and energy transition Truncó any new attempt To exploit the deposits: “Due to their prejudices, their cost will not be granted new exploration, research or concessions of exploitation of radioactive minerals, nor will new authorization requests be admitted.” Environmental problems. The risk of radioactive water contamination is another elephant in the room. A study Posted by Environmental Pollution In 2018 he documented “much higher” uranium concentrations than background geochemical levels near old mines abandoned in Salamanca. The levels in the soil ranged between 207.2 and 542.4 mg kg⁻¹, when the natural background levels are 29.8 mg kg⁻¹ for granite and 71.2 mg kg⁻¹ for slate. The study proposed environmental restoration measures, such as reforestation, in areas close to old farms. They are not entirely unfeasible. The political landscape has changed with the European Union in search of energy sovereignty and resources. The economic landscape too. With The price of upward uraniumthe Berkeley Minera company has a revived interest in its Retortillo project. The request for exploitation of this deposit was delivered before Law 7/2021 applied, but the Nuclear Safety Council also issued An unfavorable environmental report for “the low reliability and the high uncertainties of security analysis in geotechnical and hydrogeological aspects.” Uranium you have to enrich it. Although there was a political change that leads to the reactivation of Retry, the uranium that is extracted from the earth (natural uranium) barely contains 0.7% of Uranium-235, the necessary physiognable isotope for most nuclear reactors. It would be necessary to enrich uranium, a process that consists in increasing the concentration of uranium-235 to 3-5% levels for light water reactors, which are the most common. Spain does not have its own high -scale enriched uranium, or facilities in which to enrich uranium at the industrial level for use as fuel in nuclear centrals. Can Spain enrich uranium? Spain had the capacity to produce uranium concentrates (in the form of yellow cakes or Yellowcakes), But obtaining enriched uranium is a subsequent, technologically more complex and expensive process, dominated by a few countries. Today, 60% He leaves Russia and China. ENUSA (the national uranium company) already had difficulty replacing Russian enriched uranium after Commercial vetoes for the Ukraine War. Enriching it would be a major challenge. A change of direction. In the new geopolitical context, the European Union is promoting the reactivation of mining to ensure a sovereign supply of key materials for energy transition and defense. Spain is rich in Uranium, but also in resources such as copper, which is the second EU producer. Besides, It has lithiumcobalt, Coltán and possible lower land deposits. Seven of the 47 new Strategic Mining Projects promoted by the EU They will be developed in Spainalthough most face the rejection of environmental organizations for its environmental impact, such as the lithium mine in Cáceres. The epicenter of the debate. Discussions on Spanish uranium are a broader reflex of tensions: the strategic autonomy of resources, the imperatives of the energy transition, environmental protection and social acceptance of mining activity. In the end, the epicenter of the debate is the high cost of building and maintaining traditional nuclear plants in the face of renewable energy sources, of which Spain is world power. Only last year, Spain produced 148,999 GWh of renewable energy, 56.8% of Mix. If the blackout was A notice that the electricity is not prepared To stabilize large renewable energy fluctuations, what touches is wondering what are the investments in storage, investors, interconnections and energy sources alternative to pollutants combined cycles of gas to avoid another blackout. Everything is said regarding the closure of nuclear plants or the extraction of uranium in Spain, but the solar industry will not go anywhere.

The reclining seat is the great battle among plane passengers. A Neozylandesa airline believes to have the solution

May 12, 2025 by usatoday24

If you fly, it is likely that it has happened to you more than once. You are comfortably sitting in your seat, buckled belt, headphones in the ears and a good book in the hands, and suddenly (plas!) The back of the passenger in front It is about you. Your vital space is smiling. You no longer move with the same comfort. And the worst thing is that little you can do to solve it. After all, the seats are designed for that: recline. In New Zealand there is an airline that has had An idea to avoid that kind of situations. Its proposal is still limited (it applies in the premium class), but it provides at least one solution to a problem that is usually a source of infinite discussions (and even fights) on the planes. THE WAR OF THE SEATS. A year Heather Poole, a hostess of an American airline and author of A book in which he speaks of his 15 years of experience with “crazy passengers at 35,000 feet high,” he published on the CNN website An article loaded with irony about one of the big problems with which the cabin staff fought during flights: the fights triggered by the reclining seats. “In addition to the lack of Wi -Fi or a damaged entertainment system, flight assistants listen to more complaints about the reclined seats than about anything else,” Poole explains Before recounting the case of a passenger who came to threaten to punch if the traveler in front of him continued to lower his seat. “A reclining armchair can be reclined, and no one can do anything about it”, Warns the flight attendant. “If you get it or threats to hit someone you will be you who ends up expelled.” And Air New Zealand arrived. The New Zealand flag airline, Air New Zealand, has decided to take advantage of the modernization of part of its fleet to try a way to end the fights for reclining seats. The company, based in Auckland, has taken advantage of the first “reconditioning” of an aircraft 787-9 Dreamliner to replant the design of the cabins, including among other issues new seats. The aircraft includes the Business Premier, Business Premier Luxe, Premium Economy and Economy Business category. Each has its peculiarities but if we talk about the subject that worries Poole (and the rest of the world’s hostess) the interesting is the Economy Premium. In addition to adding some lateral “wings” to the seat to offer greater privacy to the passengers and expand the storage space, the New Zealand company has sought ways to ensure that if a traveler wants to bow his neck, he does not finish a few centimeters from the passenger’s chest behind him. “All seats have a fixed exterior housing, which means that their reclines does not affect the person behind,” duck. Is it the definitive solution? It is of course an interesting idea for a problem that, although it may seem anecdotal, alters the flight experience to many passengers and forces intervene often to cabin staff. The concept of reclining seat with an exterior housing that prevents the backrest from going backwards It is not new (at least in trains) and Air New Zealand limits it to its Premium Economy class. The tourist class seats of its adapted 787-9 are simpler and the company does not specify that they incorporate any novelty related to the inclination. With all the bet is interesting because the airline wants to continue modernizing its 787-9. The first of its reconditioned aircraft will be released on an Auckland-Brisbane flight on May 19, but the company is already working on a second ship in Singapore and hopes to have seven units ready for the end of the year. “The 14 Boeing 787-9 of the Air New Zealand fleet will be updated to the new cabin configuration by the end of 2026,” They clarify From the company. How serious is the problem? “The main problem is that airlines are piling too many seats in a small space. Do you remember the leg space?” Ironiza Poole. Your comment slips a key idea: optimization does not respond only to a matter of comfort, it is also (and above all) an economic issue. Airplanes have a limited capacity and conditioned by the manufacturer, but to the extent that their squares are redesigned by airlines can earn space, travelers … and money. The issue is so relevant that there are airlines that have op reduce degrees of inclination of your seats or limit Its rotation. In the sector even The idea is handled to directly install immobile seats that prevent any degree of adjustment. That without even more radical ideas, such as that of the Spanish entrepreneur Alejandro Núñez and his two height seator the places for passengers They fly standingraised by some Low Cost. Goodbye to the fights? That is the goal. And one of the advantages that a priori offer the seats of the new Air New Zealand aircraft. They are not the only ones who have sought ways to put some “peace” among the people who have to share flight hours in a limited space. There are companies that have come to design Kits that allows the front seat to be tilted and It is not so much Tiktok circulated a trick more than questionable to prevent the passenger from front to incline our lap: activate the air conditioning and guide it towards it.

Replacing the Air Force One has become a nightmare for the US. Qatar wants to fix it with a “flying palace”

May 12, 2025 by usatoday24

Air Force One. Few names have more strength than that of the US presidential plane. Ha star filmsis one of the official air transport of the United States (Next to the Nightwatch prepared for the ‘End of the world‘) And it is a strength with wings that has become an iconic vehicle. I had to renew it, and Trump is going to get out “free” The reason? ABC News affirms that the new Air Force One would be a gift by Qatar’s royal family. Trump does not deny it and is a cocktail that has set fire to US politics. Even to the most related to the president. It was renewal. He Boeing VC-25 It is the current presidential plane. It has been in service of the 35 -year -old and, although the airplanes usually have a long useful life, maintenance costs began to be unprofitable. In January 2015, the Air Force announced that they had already chosen which plane to work for the new Air Force One: the Boeing 747-8. Known as VC-25Bthe Air Force organized with Boeing an agreement to buy two 747-8 that were never delivered to a Russian airline that had gained, and thus some money was saved because it is not just buying them: also adapt them with the necessary equipment and security and create an adequate hangar. The current Air Force One Trump negative. In December 2016, before entering the White House for his first term, Donald Trump already showed his disagreement with the price of the program. Boeing is building a new Air Force One 747 for future presidents, but the costs are out of control, more than 4,000 million dollars. Cancel the order! tweeted The tycoon. The Boeing 747-8 entered into service at the beginning of the last decade and was a modernized generation, with both technological and aerodynamic improvements that, in addition, was one of the longest passenger aircraft in the world. In addition, it is of American manufacture, so it was a clear option for the new presidential plane. It was estimated that it would go into service in 2024, but delays and other problems have prolonged the operation up to, at least2027. And that is where Qatar’s royal family can change the rules of the game. A “flying palace” gift. This week, Trump will begin his state travel carousel. As happened in his previous term, Saudi Arabia will be his first destination, followed by Qatar and Arab Emirates. It is one Logic choice Due to the interest shared both in economics (they invest billions in the purchase of American weapons) and geopolitics (US bases in the region, keys to Asian domination), but apart from those treatment, Trump can return with a new presidential plane under his arm. As we read in NBCDifferent sources suggest that Trump will accept a luxurious Boeing 747-8 as a gift by the Royal Family of Qatar. One of the sources consulted by the American media is one of the White House officials, who admitted that it is true that Qatar has offered to donate a plane to the defense department, but that it is not something that will be accepted during the president’s visit. From the Catarí press department, they have been somewhat more concrete: “The possible transfer of an aircraft for temporary use such as Air Force One is currently being considered between the Ministry of Defense of Catar and the US Department of Defense, but the matter remains reviewed by the respective legal departments, and a decision has not yet been made.” Reactions. This is something that has not taken long to explode in the American political sphere. Democratic representatives have loaded Against the decision, asking for investigations on what they have described as a “flying scam” or as “the most valuable gift ever granted to a president by a foreign government.” Because we are talking about a vehicle of about 300/4 billion dollars, and there are those who have thrown sarcasm, such as Senator Chuck Schumer. “Nothing says ‘America first’ like an Air Force One sponsored by Qatar. It is not just a bribe, it is a luxury foreign influence with extra space for the legs,” Comment In X. Bernie Sanders has gone somewhat further, describing the movement as something “ridiculously corrupt” and “blatantly unconstitutional.” It is not bribery. Critics They assure which is something that must be presented and approved in Congress, because it is the practice to be followed by the Emoluments clause of the Constitution. This prohibits the president and other federal officials from accepting gifts from foreign governments without the approval of Congress, but the turn is that it would not be a gift to Trump, but to the Department of Defense. A former official of the Department of Justice spoke with NBC anonymously, commenting that bribe Trump is committed to total transparency. ” Trump himself has commented The following in its Truth social network, qualifying Qatar 747-8 as an Air Force One of Transition: “The fact that the Department of Defense receives a totally free gift from a 747 plane to temporarily replace the 40 -year -old Air Force One, in a very public and transparent transaction, annoys the corrupt Democrats so much that insist that we pay it, at the price of gold. The Democrats are world -class losers! Maga!” And after the mandate … Same Leavitt statements for ABC Newsmedium that states that White House lawyers consider that it is “legally permissible” to accept the donation of the plane due to the alleged small print of the agreement: the Catarí government will donate it to the Department of Defense to use it as Air Force One, but before the end of the president’s mandate in 2029, the plane will be donated again: to its presidential library. In this way, Trump can continue to use it as a private plane when he leaves the position. Of course, this is also controversial and organisms that fight for responsibility and ethics in Washington have shouted in … Read more

It is a relief for the world economy

May 12, 2025 by usatoday24

The United States and China have announced Monday that they have reached an agreement to temporarily reduce the import tariffs that had been announced previously. The Escalada in the Commercial War Between both countries I was having a huge impact on the economy, but now both sign a truce that can be the beginning of a new commercial balance. What happened. In a joint advertisement, both countries have indicated that they reduce their tariffs over the next 90 days, which will continue the negotiations initiated this weekend. As indicated In The New York TimesUnited States will reduce Chinese import tariffs 145% to 30%, while China will apply 10% tariffs to US imports, when that figure It was 125% before this truce. Source: The New York Times. “Shared interest”. Scott Besent, US Treasury Secretary, indicated at the press conference in Geneva that both countries have concluded that “we have a shared interest. The consensus by both delegations is that none of the parties wanted a decoupling (commercial).” China again export rare earths. Another decisions in this agreement is that China will suspend the Rare exports restrictions. This measure had been taken as retaliation Before the ads of the tariffs by the US, but now the North American country will have access to these critical materials for industries such as car, aerospace or semiconductors. A break for the world economy. This reduction in tariffs is a hopeful pause for a worrying situation. The consequences of tariffs are already being noticed in the industry and of course in the technology prices we buy. There are many companies that have tried to react in the most appropriate way to mitigate the impact of tariffs on their business and customers. The Big Tech Like Apple “With a lot of movement.” surrounding iPhone– They were being clear examples of those impacts, which also noticed Google goal. More steps back. The truce in the imposition of tariff Like that of semiconductors. It was the first sign that Donald Trump was realizing that these measures were a foot shot for the US. A Way for the Descale. Both decisions point to a renewed intention for renegotiating the terms of trade agreements between the two major world powers. Mark Williams, Capital Economics analyst, explained that this agreement is “another substantial withdrawal of the aggressive Trump administration position.” The 90 days that will allow both parties to try to reach a new agreement in the application and dimension of tariffs. Battle won from China? Analysts like Zhiwei Zhang, from Pinpoint Asset Management, explained that “from the perspective of China, the result of this meeting is a success, since China took a determined position in front of the US threat of high tariffs and ended up getting the reduction of tariffs without making significant concessions.” Uncertainty. Responsible for the European Chamber of Commerce in China indicated feeling “encouraged” for the announcement, although they made it clear that uncertainty persists Because this decision is only temporary. The Hong Kong stock index has grown by 3% after the announcement, and practically the same has happened in the case of the S&P 500 futures index.

It seemed that LaLiga could not be further blocking domains. Until it touched the festivities of the City of Madrid

Klarna presumed that AI did the work of 700 people. Its quality is so low that it is rectuming humans

May 12, 2025 by usatoday24

In June 2022, 700 Employees of the Swedish Fintech Klarna were fired. That template reduction was an absolute disaster: The announcement was made with a pre -recorded video, and also the CEO shared the personal data of those employees in LinkedIn. The story did not end there. Not much less. The AI that works for 700 people. After the dismissals, Klarna made a unique decision: to use an artificial intelligence system promoted by Openai models to replace the functions performed by those 700 people. In February 2024, those responsible for the company proudly affirmed that the assistant “is doing the job equivalent to 700 full -time agents“And they also disregard that” it is along with human agents in terms of customer satisfaction score. ” Not so fast. Klarna’s CEO and co -founder, Sebastian Siemiatkowski has started a hiring process that allows customers to always talk to a human agent. The reason is striking, especially taking into account Klarna’s ambition in its use of AI. The AI offered a low quality service. The strategy that proposed to place AI as a fundamental pillar of its support services is no longer valid. According to this CEO, “unfortunately, the cost seems to have been an evaluation factor too predominant,” and explained that “what ends up is a lower quality” in the service. Now they intend to “invest in the quality of human support” for the future. Uber type structure. In an interview With BloombergSiemiatkowski indicated that the Swedish company is pivoting a structure similar to the one Uber: workers can log in and telework for them. That, this manager indicates, will allow in the future these new hiring to replace “the few thousand human agents” that Klarna Subcontrata. Labor is sought (cheap). The pilot project for that transition has a very limited reach, but the objective is to attract candidates as students or people of rural environments. “We know that there are a lot of Klarna users who love our company and enjoy working for us,” said Siestkowski. The intention seems clear: instead of hiring professionals with experience in this area and replacing them with such profiles that will allegedly reduce costs. An erratic evolution. Klarna came to have an assessment of 45.6 billion dollars in 2021, but those decisions made that estimated value a year later It was 6,500 million of dollars. The company now expects to lift $ 1 billion With an OPA that allows to place its valuation at about 15,000 million dollars. The plans of that IPO have been postponed due to the current volatility of the markets. But the trend is clear: less human. Despite these decisions, in Klarna they create technologies such as AI will continue to impact the dimension of their template in the future. The CEO hopes that in a year they will exceed 3,000 current employees to about 2,500. We are seeing it everywhere. Other companies have suffered that “recontraction” effect. IBM fired 8,000 workers To replace them with AI, but their CEO, Arvind Krishna, explained that at the same time they are hiring a lot of programmers and sales personnel. Other companies ensure that replace humans with AI It has really worked very well, but the reality is that many are realizing that After using ia they end up investing in new hiring When needing different profiles such as the aforementioned programmers. AI is removing some jobs and promoting others. The conclusion seems to be the same in all cases. The companies that are betting on taking advantage of everything they can They manage to replace human workers by artificial intelligence systems in routine and very automated tasks. However, those same companies end up realizing that they need more programmers and specialized personnel, probably to ensure that the IAS that do the automated work do so much better than they do as a start.

How to unlock ancient iPhone when they are deactivated and tells you to try again in years

May 12, 2025 by usatoday24

Let’s explain How to unlock the old iPhone They have operating system versions prior to iOS 17. From that version you can configure the iPhone so that if you put the security code bad many times you can restore it or the iPhone is reset. But with the previous versions that does not happen. In versions prior to iOS 17, if you make many mistakes with the security code the iPhone is blocked for several minutes, or even hours. And in some extreme cases, for many years. That is why we are going to tell you the alternative you have if it has happened to you on an ancient iPhone with a system before iOS 17. I already warn that it is not a perfect solution, since requires restoring the iPhone. This means that you will lose all the data in it if you did not make a backup before it was blocked. But well, at least you can use it again. Recover an iPhone blocked for years When you have an iPhone blocked completely and extremely, with a message telling you that you have to wait several years to recover it, the only easy way to recover it is Restore it completely on your ownlosing all the data that is not in a backup. For that, you will need to have a mac with macOS 10.15 Catalina or posterior and the Finder tool. If your MAC has macOS 10.14 MOJAVE or a lower version, you need to have itunes installed. You can also do it with Windowsas long as you lower the application Apple devices. Now, you have to Force the restart of your iPhonewhat is known as a hard reset. To do so, press and release the volume up button and then lower it, then hold the ignition button until the off option appears. If your iPhone has an Home buttonthen just hold the ignition button until the screen shows you the option to pay. Now, connect the iPhone to your computer with a cable. In doing so, open the application Finder, iTunes either Apple devices Depending on the computer you have as we explain at the beginning. When you access the screen, click on the iPhone icon on the list of locations. This will take you to your iPhone’s options, and you must click on Restore To do it on the device. This will begin the process of restoring the iPhone, format it to delete all data and reinstall iOS to stay as if you just bought it. It is possible that in the process you ask you to write the iPhone security code, but if you do not remember you can use other methods such as the password of your Apple account.

He claims to have a training method for his AI 88% cheaper

May 12, 2025 by usatoday24

The Chinese company High-Flyer broke into the market in the market of the artificial intelligence (AI) At the end of last January. Deepseek, his proposal, has made its way among its competitors thanks to its open nature and its benefitsbut the authentic debate has revolved for several weeks Around the cost of training your models. And it is that according to its creators they were barely spent 5.6 million dollars In this process. Three and a half months later this figure is still unbelievable, so it is reasonable to contemplate it with distrust. Anyway, Deepseek has put on the table the possibility of facing the training of the new models of investing much less money than the one spent by US companies OpenAi, Google or Anthropic in the tuning of theirs. Now it is the Chinese technological giant Alibaba who seems to be following The same path that has already traveled Depseek. And it is that it claims to have developed a AI models training system that reduces the cost almost 90%, which presumably will have a positive impact on AI search capabilities. Alibaba’s jewel is called Zerostoch The strategy that Alibaba engineers have devised to reduce the cost of training their AI models is ingenious. And instead of interacting with real search engines during this process, Zerostoch, which is what is called its technology, improves search capabilities carrying out simulations. To understand why this approach is much cheaper, we need to keep in mind that the costs associated with the redirection of commercial search engines are usually high. Alibaba has put a model that behaves as a search engine that is capable of training other AI models According to Alibaba Send 64,000 consultations to the Google search engine through an API has an approximate cost of $ 586.70, while generating the appropriate responses for training by means of an AI model of 14,000 million parameters has an approximate cost of 70.80 dollars, which represents an 88% cheaper. In practice, what Alibaba engineers seem to have achieved is to tune a model that behaves as a search engine that is capable of training other AI models so that they are able to solve consultations. This scenario has a very evident advantage: training no longer requires interaction with external search infrastructures. Alibaba, as we all know, is a gigantic company, but from now on this strategy can be used by much smaller companies to train their own AI models without the need to face a great investment in this process. In addition, presumably this technology will improve both the search capabilities of AI models and the ability with which they carry out the reasoning processes. At the moment Alibaba has used Zerostoch to improve the capabilities of his Quark model, which for just three days has been capable, always according to its creators, to combine the internet search and advanced reasoning capabilities to resolve inference and deliver precise responses to complex consultations.

NASA, NASA, NASA always sends rockets, rockets, rockets (but also balloons that turn the world)

More modest and ignored than rockets, stratospheric balloons They are crucial for many scientific research NASA. The last of these huge balloons has just concluded its mission after 17 days circumnavating the southern hemisphere. 17 days back to the world. In early May, NASA ended the first flight of its 2025 superpression balloons campaign. A stratospheric balloon drew a route around the average latitudes of the southern hemisphere, furrowing the sky for 17 days, 13 hours and 47 minutes. Launched April 17 from Wanaka airportin New Zealand, the globe completed a complete circumnavigation on May 3, and merited the next day in the Pacific Ocean, 1,300 kilometers from the east coast of New Zealand. Straight to the bottom of the sea. Although the mission met the minimum requirements, NASA’s team had been monitoring a possible leak. The balloon lost altitude during the night when crossing areas with colder temperatures, so that their operators decided to finish the flight over the Pacific, without the possibility of recovering the payload. The space agency leaves nothing to chance, even in case of ruling. This type of balloons uses the two -tons payload itself as ballast to sink the entire flight train to the ocean bottom as quickly as possible. In this way, the globe is prevented from remaining in the primary zone of the water column, where most of the marine species. The mission. In addition to trying a new superpression balloon design, this first 2025 flight transported the Hiwind missionwhose objective was to measure the neutral wind in the thermosfera, the layer of the Earth’s atmosphere that is between the mesosphere and the exosphere, to help scientists understand and predict changes in the ionosphere, which can affect communication and navigation systems. Since the mission ended early (the globe that has been in flight lasted more time 57 days), NASA will thoroughly investigate the cause of altitude loss to reduce the probability that a similar problem occurs on future flights. The second campaign superpression balloon It was released on Saturday, May 3 and can be followed in real time on the NASA website. What are the superpression balloons. Are Pumpkin -shaped balloons whose structures, completely sealed, maintain a positive internal pressure and an almost constant volume, which allows them greater altitude stability and flights of much longer duration, since the loss of gas is minimal. With a diameter of 150 meters, the most common volume is 1.13 million cubic meters. A balloon of this size could house a football stadium inside when it is completely inflated. They fly to altitudes of up to 36 kilometers, more than double the altitude of commercial airplanes. And they have been playing for some time as an alternative to space releases For space tourism. What are these balloons for. NASA’s scientific balloons are a low cost form of accessing the stratosphere to do research on land or outer space. Some carry telescopes on board. The NASA scientific balloons program performs, between 10 and 15 individual flights every year. The heavens continue to offer valuable opportunities for science, without always turning on the engines of a rocket.
