Hubble is slowly falling, but NASA doesn’t know if it’s worth rescuing

by

At the end of this month, the launch of Link, the ship developed by the Katalyst Space company, is scheduled to rescue the Neil Gehrels Swift Telescopewhose orbit has been declining in recent years due to atmospheric resistance. Although the development of this mission has been expensive, NASA considers that it has been a minimal investment compared to all the return that can be generated by keeping the telescope in operation for a few more years. Therefore, given that Hubble is also deorbiting, the question arises whether it would be interesting to do the same. It is clear that this telescope can still provide a lot of science. However, it is an old instrument, so its maintenance and operation are quite expensive. That is why NASA is doing calculations to discern whether it would be interesting to develop a ship similar to Link for its rescue or if, ultimately, it is more profitable to let it deorbit. Almost 100 million dollars in one year. During 2025, NASA invested 98.8 million dollars on the Hubble Space Telescope. Only the much newer James Webb required more investment. We must not forget that Hubble was launched in 1990. It is very old, so today it is more expensive to maintain and even operate with it. But it’s in good shape. Despite needing so much investment, Hubble is in great shape. Many saw the launch of James Webb as an opportunity for Hubble to retire. The networks were filled with photographs in which images of the same point taken by one telescope or another were compared, always much more clearly in the James Webb. However, they are not exclusive telescopes, but complementary. Hubble focuses on detecting emissions in visible and ultraviolet light, while James Webb specializes in near and mid-infrared. It is true that James Webb can see through dust and gasgo further and take images with higher resolution. However, there are objects that can only be observed at the wavelengths at which Hubble works. Today he continues to make great discoveries and if he were to deorbit and retire he would leave a very big void in space research. The ideal would be to last 15 more years. The Habitable Worlds Observatory is scheduled to launch in the 2040sa large telescope, much more advanced than Hubble, which will also work in visible and ultraviolet light. This could, in a way, retire Hubble. Until then, it remains a necessary telescope. You have to do calculations. With the Swift, the profitability of launching a ship to their rescue was very clear. For Hubble, more calculations will have to be made, since a ship larger than Link would also be needed. Still, given how useful this telescope has been and continues to be, it would not be strange if it is still profitable to recover it. If this is not done, re-entry into the Earth’s atmosphere could occur. in 2029, with a median set in 2033. There would be no time to get his replacement ready. It is a very important detail to take into account. Image| NASA Hubble Space Telescope In Xataka | The James Webb has broken another historical record: a supermassive black hole older than expected

NASA’s plan to capture a falling telescope before it burns up in the atmosphere

by

After more than 20 years carrying out their work to perfectiona NASA space telescope is about to fall to Earth and burn up in its atmosphere. This would be very serious, both because of the possibility of uncontrolled debris being generated and because of the loss of the valuable work that this instrument is carrying out. For this reason, the US space agency has already teamed up with a private company to launch a ship into space capable of hunting the telescope and sending it to a safer orbit. Key dates. The protagonist of this story is the Neil Gehrels Swift Observatory. According to the latest measurementscarried out in November 2025, there is a 50% risk that this telescope will leave its orbit and fall to Earth in June 2026. In addition, the risk rises to 90% before 2027. For this reason, NASA has granted $30 million to the company Katalyst to develop a robotic spacecraft capable of capturing the telescope and raising it to a safer orbit. The ship is called LINK and its development is going from strength to strength, although there is still no launch date. The biter bit. Neil Gehrels Swift was sent to space in 2024 to capture and study the explosions of gamma rays. Since then it has provided very useful information; But unfortunately, this could change soon. A subdued atmosphere. The problem lies in the attenuation of the Earth’s atmosphere. When we travel to space, this does not disappear suddenly, but rather fades little by little. Such a weak atmosphere has the ability to slow down spacecraft and send them into a lower orbit. If solar storms are added to this, capable of swelling the atmosphere, great aerodynamic resistance is produced. We are currently in a cycle of high solar activity, which reached its peak in October 2024. This possibly pushed the telescope to its limits, placing it in an unstable orbit, from which it could leave at any time. Work against the clock. NASA and Katalyst are working around the clock to launch the LINK spacecraft on time. But in the meantime, the telescope must hold on. For this reason, some of its instruments have been turned off and their operations modified, in order to minimize their energy consumption. This has made it possible to reposition its solar panels and, thereby, reduce their resistance. Sooner or later this will not be enough, but at least it can buy some time until the LINK launch can take place. In the absence of ground platforms, it is a good plane. In order to hunt this telescope in the orbit in which it is located, a launch configuration is necessary that is not available on any of the platforms available to NASA. Therefore, it is planned to launch the ship directly from an airplane. Thus, the trajectory can be adjusted much better. In short, this will be a unique event in history. A telescope has never been caught on the fly. For now we will have to wait, but we will be very attentive to the release dates.

Ukraine’s latest tactic is an explosive turn for the war. It’s called “letting in,” and the Russians are falling into the trap.

by

Since the Russian invasion of Ukraine in 2022, the front has been mutating with all kinds of tactics who sought to wear down the enemy. The arrival of drones everything has changedbut the strategies and ingenuity In the use of artillery they have remained a fundamental asset for the advance or defense of the front. For this reason, Ukraine’s latest strategy has disconcerted the Russians. When they reach the bunkers there is no one, and then the surprise comes. Win by letting in. Ukraine is applying a more flexible and lethal defense consisting in “pre-register” their artillery on their own front-line positions, so that when the Russians assault and capture them, they literally enter an already calibrated point to be destroyed: the fort falls, the enemy concentrates, and then comes the massive punishment that turns Russian success into a death trap. After that blow, a Ukrainian assault branch recover the points again devastated, closing a cycle that maximizes ranged damage and reduces the exposure of own infantry, something key in a context of growing shortage of trained soldiers. This logic, denounced even by pro-Russian voices as the strategy of “letting in” is actually a way of imposing the pace: it is not about always preventing them from advancing, but about making each advance expensive, slow and bloody. The “death zone” as doctrine. The tactic works because the battlefield has become in a “kill zone” permanent where the defender attempts to maintain a deadly gap between the leading edge and the rear: artillery is placed further back, out of the usual range of rival drones, and forward positions are fortified to attract attackswaiting for the enemy to enter to destroy them right there with fire and drones. The drone operators They not only strike at the front, they also hunt for supply and reinforcement routes, and any activity near “newly taken” positions becomes visible and attackable. Added to this is the constant mining (including remote) and the use of “ambushers” in the few possible logistical axes, so that the attacker not only pays to capture, but also pays twice as much to try to consolidate. The “let in” tactic after pre-registering a position The decisive blow. The most surprising point about this approach is that the defender does not seek so much to “hold every meter” as to prevent the attacker deploy your second step– When the advancing force attempts to bring in specialized reinforcements (e.g. drone operators to hold the ground), the defender launches fast local offensiveseven if they cost material, to keep the death zone intact and keep the enemy trapped in a space where they cannot settle. Thus, the advance exists on paper or in the drone image, but it becomes tactically sterile: you capture something and, before transforming it into a usable position, it becomes a slaughterhouse, like is described in sectors like Kupiansk. It is a war where “letting in” is not an extra: it is the moment in which the enemy advance stops being progress and becomes a loss. The psychological and moral consequence. These types of dynamics are eroding the offensive will because it forces us to choose between kilometers and livesespecially the “faces” of competent soldiers who know how to move in that death zone: It’s not just that advancement costs, it’s that it costs exactly the most valuable thing. From this arises a dilemma on the front itself: advancing in a big way without preparation means burn trained unitsbut advancing “minimally” or little to be able to report presence saves resources… at the cost of generating absurd situations where you can no longer request fire on positions that officially “they are yours”although in reality they are being crushed or disputed. In this framework, the information war of territorial control is mixed with real survival, and “progress” becomes a very diffuse decision. The technological revolution to the rescue. we have been counting. The bottom line is that Ukraine is at the center of a military transformation: soldiers are the most expensive and difficult resource to replace, while unmanned systems have passed to dominate the combatexpanding on an industrial scale, lowering costs and multiplying impact. The front is increasingly managed from the rear or bunkers with operators controlling the space, and attempts at “classic” breaches become almost suicidal: the key is no longer to launch columns, but to disperse, camouflage and gradually push the death zone back. As the war evolves into swarms, AI coordination and persistent attacks, the advantage is not having the most expensive weapon, but having thousands of cheap weaponsreliable communications networks and the ability to update systems non-stop. The coming war. Thus, the strategic decision moves to logistics and industry: cut off land routes, protect supplies, attack factorieslogistics centers and hidden commands, and do so with reusable media and unmanned is increasingly determining. Victories depend on producing drones en massesecure components, sustain communications Starlink type and dominate the cybernetic layer that can blind, uncoordinate or paralyze an entire front. That is why the strategy to “let in” It does not seem like an isolated trick, but rather a direct consequence of the new battlefield: if the first to enter dies, the one who waits and finishes with precision (with drones, mines, artillery and digital coordination) keeps the initiative even if it seems that is receding.

A video of a Russian soldier ignoring a bomb falling on him is the clue to something deeper in Ukraine

by

This circulating a clip as brief as it is disturbing: what appears to be a fragmentation munition falls at a soldier’s feet, explodes practically beneath him and, against all logic, the man continues walking as if nothing had happened, “ignoring” the immediate impact of a detonation that, by pure physics, should have destroyed him or at least knocked him down and left him incapacitated. The explanation points to a tactic that is not new. What doesn’t fit. The most striking from the video It is not just that he remains standing, but the absence of the instinctive reaction that any body has to pain and shock, as if the nervous system were disconnected or anesthetized. And here comes the detail that makes the scene even more disturbing: according to Canadian analyst Roythe scene suggests that it is a Russian soldier, and that what we see is not a typical Ukrainian attack, but a deliberate attempt to eliminate him by his own people, perhaps because he was trying to defect. In that reading, the explosion would not be bad luck, but rather a covert execution, with what appears to be una OFSP-0.5, launched with the intention of cutting his retreat short and erasing any uncomfortable history before he crosses a line or surrenders. The “zombies” of Bakhmut. The image does not appear out of nowhere: it fits within a sensation that is repeated from the hardest moments of the siege at Bakhmutwhen Ukrainian fighters they described Russian attacks that seemed written by someone who doesn’t understand human survival. Waves of men advancing without coordination, without visible tactical logic, walking almost in a straight line towards enemy fire, with stories that spoke of soldiers who kept appearingalthough the first had already been killed, and with a strange passivity even under bombardment. We talk about videos where soldiers were seen move slowlystaggering, as if they were stuck in a thick dream, unable to move away even as grenades fell around them. In that framework, the video soldier current seems like the extreme version of the same impression. The drug hypothesis. For months, many Ukrainians have sustained an uncomfortable idea: that part of these attacks are not explained only by incompetence or desperation, but by soldiers “doped” envoyswith substances that reduce fear and disconnect prudence. The accusation appears in direct testimonies: men who seem euphoric or absent, who advance without understanding what they are doing, who do not retreat even if death is obvious, who react late or not at all. Not only that. Suspicion persists because, from a military point of view, the temptation it’s too clear: If what you need is infantry who will walk toward fire, who will endure a corridor battered by artillery, who will not be slowed by anxiety, and who will execute orders in an environment where instinct would say “flight,” a stimulant or narcotic mixture can make a soldier a more manageable asset. Pervitin, an early form of methamphetamine, which was widely used in Nazi Germany The Nazi shadow. To understand why this idea is not science fiction, just look at the most famous historical precedent: Nazi Germany led drug use combat at an industrial level with Pervitina low-dose amphetamine similar to modern methamphetamine that was first popularized in civilian society and then became a military multiplier. wanted something simple: reduce sleep, raise morale, reduce fear, increase aggression and sustain the execution of tasks without rest for days, just what is needed for rapid offensives and to maintain the rhythm when the body should collapse. And it wasn’t just the Nazis, also the allies. Super soldiers. That logic fit like a key in the blitzkrieg lock: continuous movements, mechanized attacks, advance without pause, a sensation of permanent thrust that overwhelmed the enemy not only because of the power, but because of the ability to not stop. He myth of the “super soldier” It wasn’t a futuristic helmet: it was a pill. And if that episode taught anything, it is that armies, when they believe they can gain an advantage or sustain performance, usually put immediate effectiveness before medium-term human cost. Soldiers under the influence. The pattern of effects attributed to this type of stimulant is perfectly compatible with what appears in many stories of the war: less fear, more aggressiveness, less need to sleep, more resistance to fatigue and a certain ease in executing simple commands even in extreme conditions. The price is usually the psychological and physical toll: dependency, depression, impulsivity, loss of judgment, and a progressive degradation of the soldier as a functional person outside of the moment of combat. On the front line, however, that bill is irrelevant to a short-term planner: if what you need is for someone to cross a field of fire today, you care little about what happens to them a month from now. That’s why video on networks It is so symbolic and striking: it seems to be the exact moment in which the body stops behaving like a human that preserves its life and begins to behave like a moving object that only obeys the forward vector. The other side of the coin. However, there is an essential nuance: “zombie” behavior does not always involve drugs. It may simply be the ugliest version from reality: extreme coldlack of equipment, exhaustion, hungeraccumulated sleep, sustained stress and the confusion of a mind that shuts down. The early hypothermiafor example, fits brutally with many clips: slowness, clumsiness, difficulty processing stimuli, confused speech, lost gaze. And in the Russian case there is also a historical tradition of war “fuel” much more mundane: alcohol as a tactical and psychological value, from vodka rations in World War II (used to combat the cold and to give courage before attacks) until modern episodes of indiscipline and documented drunkenness. A sign of the times. In short, the video that has gone viral In networks it leaves that somewhat absurd feeling of “two options”: either it was a Terminator, or the soldier was under some type … Read more

This is how the “impossible” photo of the man falling into the Sun was made

by

It seems like a montage, but it is so real that it has gone around the world just when AI was making surreal images stop impressing us. Andrew McCarthy’s “The Fall of Icarus” has shown that there are still ways to outdo the machine with technical precision and months of planning. Logistical madness. In the photo, a backlit silhouette appears to have launched itself in free fall over the Sun. It is the skydiver Gabriel C. Brown transiting in front of a particularly active solar disk. On the other side of the telescope, the famous astrophotographer Andrew McCarthywhich had begun planning the capture at the beginning of the year. It is, quite possibly, the first photo of this type, since the list of variables to control was insane. They needed the optimal sun angle, a safe height for Brown to launch from, and a perfectly calculated glide path between the sun and the camera. Three-way communication. It was 9 in the morning in the Arizona desert. McCarthy had his telescopes ready and was in constant communication with both Gabriel Brown, the skydiver, and Jim Hamberlin, the pilot of the paramotor from which he would launch. McCarthy followed the aircraft with his telescope and, once it was aligned with the Sun, gave the order. “Okay, I’ll see you,” he said over the radio. “Jump, jump, jump!” Brown jumped at about 1,070 meters above sea level with the engine idling to ensure a perfect angle. “I got it, man!” he heard him say on the radio. The sixth time was the charm. McCarthy told Live Science that the biggest challenge had been finding the paramotor in the sky. Although it was about 2.4 km from its position, the point of the shot was to capture in detail the Sun, which was 50 million times the same distance. It took the team six attempts to correctly align the aircraft with the photographer’s position on the ground. When push came to shove, they could only make one jump, as folding the parachute for a second attempt would have taken too long. Is it really not a setup? It is not, and the secret is in the telescope. As explained PetaPixelcarried a hydrogen-alpha filter to block all sunlight except for a very specific red wavelength that emits incandescent hydrogen. This is how those infernal images of the solar chromosphere are taken: the layer of active “fire” on the surface of the Sun, with its filaments and protuberances especially visible during times of greater solar activity. It is not very different from how other photos of rockets and space stations passing in front of the Sun are taken, but with extra planning and audacity so that the protagonist of the image is, for the first time, a tiny person.

Elon Musk boasted of having created an “apocalypse-proof” car. Now the Tesla Cybertruck’s headlights are falling out

by

Who doesn’t know a C15, prays to any Tesla Cybertruck with this title we headed this article in July 2024. We did it because on social networks it was already common to find comparisons between a Tesla Cybertruck which began selling just half a year before for a price close to $100,000 (sometimes much higher) with the car of “a Spanish farmer flying with three bags of fertilizer and a pregnant sheep in the trunk”, as this X user described. It was no wonder. Since it was first announcedElon Musk did not stop boasting that Tesla’s future electric car was nothing short of indestructible. A story that began crack when, live, the car glass itself could not resist the launch of a steel ball that, in theory, should not have caused any scratches. Now, less than two years after the car went on sale we know that the crack has been getting bigger and bigger. Because Tesla has recalled its Cybertruck for review. This time there have been 6,200 units. It is the tenth time in less than 24 months. Now, the headlights are going out. Indestructible, when it does not self-destruct Elon Musk boasted during the Tesla Cybertruck launch event about having a car “apocalypse proof”. He was talking, we assume, about real apocalypses, not metaphorical ones like the one they are experiencing Tesla sales in Europe. Beyond the jokes, what the owner of the company wanted to show is that he had something like a “armored street car”. In Xataka We already explained why a car that does not deform is a bad idea. If the car does not absorb the impact, it is the passenger who suffers the impact against himself. We are talking, of course, about cars that are on the street, working with all the guarantees. The problem for Tesla is that it keeps call cars for inspection. In the first year he had to do five calls for review. Today it has already been 10 and there are two full months of 2025 ahead, they collect in Electrek. While it is true that some of the problems have been solved with simple software updates, on other occasions they have had to go to the workshop because they were losing pieces in progress. The problem, everything indicates, is the same as on this occasion. The Tesla Cybertruck has some unusual headlights falling out, according to the American media. That is why the NHTSA has had to activate a recall so that 6,197 Tesla cars return to facilities. And Tesla sells headlights that can be installed on the roof of the vehicle as an accessory in its after-sales network, expanding the car’s off-road characteristics. The problem is that those headlights fall out. The glue simply cannot withstand their weight and in some circumstances it ends up expiring. This It hasn’t been the first time that Tesla has problems with the glue used, which has led to calls for review because, among other elements, the decorative molding of the A pillar, the one located on the side of the windshield, fell off. Beyond the possible fun of having an indestructible car that pieces are falling off while movingTesla is experiencing an ordeal with the electric off-roader. The company had the opportunity to make it a flagship, aspirational model and always sell it at a very high price but without aspirations of turning it into a mass product. like Mercedes does with its G-Class. However, it opted for the opposite and now finds itself unable to put the promised versions on the market at affordable prices. But, above all, it does not seem to be selling the expected numbers. And the company says it has a production line ready capable of produce 125,000 units each year. Musk even boasted that they expected sell more than 250,000 units annually. Electrek They point out that less than 65,000 units have been sold since November 2023.

is falling silently since 2022

by

After escalating during the pandemic to higher levels of its history, the price of rent in the United States started to retreat for the first time in years. The shift is neither punctual nor local: it is now observed on a sustained basis in most large cities and has lasted long enough to be considered a phase change in the market, not a seasonal blip. The question seems clear: why on earth did the rent begin to be transferred precisely now and not before? An unusual twist. After two years of historic increases driven by the pandemic shockrents in the United States have almost three consecutive years correcting National data places the average rent 3-3.5% below from the maximum of August 2022, with interannual decreases chained in the 50 largest markets. That correction is striking for a reason. very simple: It occurs in a country with a chronic housing deficit and with a still stressed cost of living. It is not a collapse, but a normalization after an extreme phase: because even with the decrease, the typical rent is still 20-22% above 2021. Austin as a laboratory. It we count a few months ago. Austin possibly offers the compressed version of what has happened on a national scale: after a boom in demand (internal migration, arrival of companies, cheap credit), the market responded with an expansion of unprecedented offer (an increase of more than 8% in the housing stock in a few years, with permits at rates that surpassed other comparable cities) and a subsequent slowdown due to the rapid rise in interest rates. The combined effect has led to rent drops of 22% from highs and sales price declines of 10-18%. The Austin case demonstrates that when the bottleneck is attacked on the supply side, the price falls before demand is destroyed due to poverty: it cools due to saturation, not due to collapse. National evidence. The pattern is common: in 2024 they were delivered more than 600,000 homes multifamily, the largest flow since 1986. There are still 686,000 under construction (well above the historical average) and 7.1% vacancymaximum of the series. A greater number of competing units forces prices to be lowered or free weeks to be granted to accelerate occupancy. The time that passes from when a home is published on the market until the contract is signed with a tenant now takes longer: 31 days on average compared to 19-20 days at the peak of tightness in 2021. The macro result is the loss of owners’ ability to raise prices in a market where the tenant has regained the margin of choice. Fall mechanics. The 2020-2022 phase combined demand shock (sudden migration + very low rates + change in preferences) with insufficient supply After a decade of under-construction post-2008, the price rose. In 2023-2025 reverse the asymmetry: the pipeline (the set of homes in the process of entering the market, but that have not yet become available) during the boom is delivered just when demand is cools due to high rates and the return of some migratory flows. What happens then? That the excess of units leads to greater vacancy, and vacancy is the nuclear variable that sets the price: after a certain threshold the expected income per empty unit falls more than it is worth keeping the rent high, and the owner adjust the price before than empty time. The fall is not structural but cyclical: if the supply were to stop completely, the pressure would return, as analysts already warn in the same Austin case. Uneven geography. The most intense decreases are concentrated in the Sun Belt markets (Austin, Phoenix, Denver, San Antonio, Orlando, Dallas), where production was faster and vacancy was higher. Markets with expensive land and regulatory barriers (cities such as San Francisco, New York, the NE coast and some Midwest nodes) show even rises because there the supply adjustment arrived late or simply did not arrive. This also confirms the direct relationship between the pace of permits/construction and price moderation: where construction was allowed, the rent fell, and where it was not, it continued to rise. It’s a correction. Most analysts agree on the same explanation. Despite the “rents are falling” narrative, the benchmark matters: the current absolute level is still well above pre-COVID, and the rent-to-income ratio has only returned to “manageable” zone (~23%) in a section of cities, and in areas like Miami or the NE coast it is still overflowing. That is why the experts they underline That anyone who expects to return to 2019 prices does not understand the basis: the new housing built is higher because the cost factors (land, insurance, construction, structural inflation) have not reversed, which suggests that the downward phase has a ceiling. Exportable lesson. The factor that can be copied is not the United States Federal Reserve or migration, but rather the supply elasticity: Austin proves, with an example empirical and measurablethat by authorizing and delivering new housing in large and sustained volumes, the rent stops being a fatalistic variable and begins to behave as an acceptable price due to competition. The rest of the country reproduces the same pattern where supply entered on a scale, and where it did not enter, the price simply did not weaken. Image | Pexels, Eric R.

The Arctic cold was the ideal barrier against invasive species. Now that barrier is falling

by

The Arctic Ocean is one of the hot points as far as climate change is concerned. Separated from the surface by polar ice, this ocean is a place with its own characteristics that go beyond its icy temperature. The barrier falls. A new study headed by researchers at British Antarctic Survey (BAS) He has found evidence of the arrival of an invasive species of Percebe to the waters of the Canadian Antarctic. This has led the team to conclude that the barrier that previously represented the low temperatures of the polar ocean is falling. Amphibalanus Impherevisus. The species in question is a type of Balánido sometimes known as bay’s percebe (Amphibalanus Impherevisus). These crustaceans are disturbed in a distant way with the common perclabes (Cornucopia policipes), but its presence is considered a problem and not A food source. The species has already become a regular of the waters of Europe and the Pacific Ocean, where it causes problems when attached to ships, pipes and infrastructure of different types. However, until now it had remained absent in the waters of the Canadian Arctic. EADN. The detection of the invasive species was carried out thanks to the study of the bars coding of the Environmental DNA (Edna). Living beings are leaving our genetic imprint in our environment: detached cells, waste and other biological remains. This technique allows to detect the presence of a species (or several) without finding a single specimen, only through environmental samples, in this case, water. The details of the study were Published in an article In the magazine Global Change Biology. Climate change, the great suspect. The Arctic is one of the regions most affected by climate change. There are two factors, both related to the increase in temperatures in this region, which have contributed to the expansion of this percebe. The first factor is the increase in maritime traffic of the Arctic associated with the thaw and the opening of new routes. Generally, the team explains, these invasive species usually arrive in the ships of the ships or in their ballast tanks. The second factor is that the waters of the Canadian Arctic no longer present such hostile conditions for the proliferation of foreign species. “Climate change is really in the nucleus of this problem. The ships are increasing in number because the reduction of sea ice has opened new nautical routes. It adds to this that the invasive species that the ships bring to the Arctic also are more likely to survive and establish populations due to the warmest temperatures of the water,” explained in a press release Elizabeth Boyse, who led the study. An issue to clarify. According to the team responsible for the study, there are still details to corroborate with respect to the spread of this species in the Canadian Arctic, starting to know if the DNA detected responded to larvae in transit or a more stable and fruitful population. To know this type of detail, it will be necessary to complement the study with other techniques, such as direct observation of animals.

The hours worked are falling so much in the Netherlands that, unintentionally, they are adopting the four -day week

by

When talking about countries with high productivity, all eyes tend to Go to Germany or Ireland. However, the Netherlands has become a European reference when it comes to significantly reducing the volume of working hours in its days, naturally approaching the four -day week model. This trend attracts attention both for its impact on everyday life and for the country’s economic data, banishing alarmist theories About economic ruin. According to An analysis of the Financial Timesthe Dutch enjoy a high quality of life, partly thanks to their system of Flexible and well -paid employmentwhich has evolved to prioritize personal well -being over the traditional model Based on long days. Netherlands and its reduced day. According The published by the 4 Days Week FoundationThe Netherlands have structured its labor market so that the full day is not the most widespread model and a large part of the employees prefer to work less hours voluntarily. However, far from being conceived as a precariousness model, it has become an example of balance Between work and professional life. According to data Eurostat of 2023, the middle day in the Netherlands is the lowest in Europe with only 32.2 hours worked, compared to 36.4 hours in Spain or 35.5 hours in Ireland. According to the data published by the Financial Timesaround 50% of the Dutch work part -time, and the proportion is even greater among women, which reach up to 75%. Not only does you work less in part -time days. Beyond the obvious cut involved in working under a model of part -timefull -time days are also from the short ones in Europe with 39.1 hours, only surpassed by Denmark with 38.7 hours per week. In Spain, the Real full day It stands at 40.2 hours. Being shorter, the Dutch tend to compress it in four days instead of five. Bert Colejn, an Ing Bank economist, assured the Financial Times That “the four -day work week has become very, very common. I work five days, sometimes they criticize me for working five days!” Greater productivity and better salaries. The Eurostat data They emphasize that Holland is among countries with Greater productivity per hour worked, standing at 45.3 euros per hour, compared to 29.4 euros in Spain, but far from the productivity of the Scandinavian countries that or Ireland that exceed 60 euros per hour worked. This conjunction of high productivity and reduced days has caused a situation of salary precariousness to be generated, but, on the contrary, Holland has maintained wages above the European average. According to Eurostatthe average of the gross salaries of Holland, adjusted by purchasing power (PPA), is 16.2 euros per hour, while in Spain it is 11.8 euros per hour. The European average is 14.9 euros per hour. Netherlands does not have four -day work week. In strict terms, the Netherlands have not applied any day reduction policy (such as Yes, Spain tries to do it) or four -day workday. However, almost without proposing it, the Dutch labor market has adjusted so that, at the practical level, its companies have implemented the working day of four days without wage reduction after decades of conciliation policies.

The teleworking is falling in all of Spain. In all? No, an village resists the invader: the officials

by

Far from the rise that He lived during 2020the teleworking has entered into A downward trend In the private sector. The face -to -face consolidates as the model preferred by companieswith offices that recover prominence. Given that reduction, a model has gained prominence: the Hybrid Day. However, there is an area in which teleworking seems to resist this setback: Public administration. Companies return to the office. Companies seem to have spent page with teleworking, and bet on the return to the face -to -face. According to the report ‘Digital Society in Spain 2024‘ Published by the National Observatory of Technology and Society (ONTSI), 69.9% of employed people always work away from home, compared to 30.1% that telework to some extent. Of that percentage of teleworking, only 9% of the total does so permanently from home (something that also confirms INE data), while 21.1% apply it under a model of Hybrid Day with between two and four face -to -face work day. The public sector walks in the opposite direction. Despite the tendency towards the face -to -face of the private sector, the General State Administration maintains much higher figures of employees that telework, and this trend does not seem to have come to an end. According to 2024 data publishedby The economist49.15% of the officials and employees of the State Administration are welcomed to teleworking. This percentage is equivalent to about 87,618 public workers who carry out their work remotely, mainly, with a maximum of three weekly days. This difference in approach to the teleworking of the State Administration adds points, Next to the salary or labor stability, so that public employment has become the Preferred Labor Alternative For many employees, in the face of the temporality, precariousness and face -to -face of the private sector. More public teleworking. The Digital transformation The administration has allowed progress in the implementation of teleworking, especially in those positions that do not require direct contact with the citizen. A recent example is starred by the Basque Government, which has reached an agreement with the unions to increase teleworking two days a week to both officials and labor personnel, such and As you collect The Basque newspaper. However, the most relevant thing about these teleworking measures that are being adopted in the administration is that the criterion ceases to focus on the nature of the job, to focus on the tasks that can be done remote. This task approach opens a new way when organizing public employment, traditionally face -to -face and bureaucratized. Unique criteria. The great “but” of this commitment to maintain and even expand teleworking in public administrations is the lack of a unique criterion for the different administrations. The General State Administration has its own norms included in article 47 bis of the Basic Statute Law of the Public Employee. However, each autonomous community and municipalities have power to regulate the work model of its officials, so there is no unique rule that regulates it, although tasks can be similar. For example, the Junta de Andalucía has just regulated the remote day of its officials, limiting it to 40% of its day. That is, two days, in front of The three days which are allowed in the General State Administration. Teleworking in state administration. As It is established In the basic statute of the public employee, the State Administration allows to telework up to three days per week, “provided that the nature of the position allows and the adequate provision of the service is guaranteed.” This formula has been mainly implanted in those bodies that They perform technical tasksof analysis or information management.
