is being played in the skies of Atacama and the Andes

The scene took place in the middle of the Cold War, when several British astronomers detected a periodic signal from a radio telescope so strange and precise that they came to name it internally. as “LGM-1”: Little Green Men, “little green men.” For weeks, some scientists even seriously contemplated the possibility that it was an artificial message coming from space… until they discovered that they had just found the first pulsar in history. The new space race passes through South America. The rivalry between the United States and China is no longer played only in Taiwan, the Pacific or the chip industry. I counted the weekend the new york times which is also moving toward some of the clearest skies on the planet, in places like Atacama, the Argentine Andes or Patagonia. What for decades were simple astronomical projects shared between universities has been transformed into a field of strategic competition. Washington suspects that part of Chinese space infrastructure in South America can be used not only to observe deep space, but also to track satellites, support military communications or expand Beijing’s technological capacity in the Western Hemisphere. The consequence is a kind of new Cold War where antennas, radio telescopes and space stations begin to be seen as top-level geopolitical assets. The radio telescope that was frozen. The most obvious case is in the Argentine province of San Juan. Over there remains paralyzed a gigantic Chinese radio telescope that was going to become the largest in South America. Officially, the project had scientific purposes: to study radio waves from space and collaborate with Argentine astronomers. But Washington began to press to Buenos Aires for fear that the system could be used to track US satellites or reinforce Chinese space capabilities. The important detail is that this pressure began under Biden and continued with Trumpshowing that concern is already part of the American strategic consensus. Today, the antenna remains disassembled and part of its components are still blocked in Argentine customs. Atacama and the value of clean skies. The dispute has a lot to do with geography. Chile and Argentina have some of the best skies of the planet for space observation thanks to its altitude, dryness and absence of light pollution. That is why they have been attracting European telescopes for decades, Americans and asians. However, the arrival of Chinese projects changed the political balance around these observatories. In Chile, a Chinese complex of one hundred telescopes in Atacama ended up blocked after strong diplomatic pressure from Washington. Officially, the project would serve to monitor asteroids and cosmic phenomena, but the United States feared that the infrastructure would have much broader strategic applications. The road built to the observatory is still there, although the complex never got up. The fear of “dual use”. The real core of the problem is the “dual use” concept. Many civilian space technologies can be easily adapted to military or intelligence roles. A radio telescope capable of capturing weak signals from distant galaxies can also help monitor satellites or orbital communications. That fear explains why Washington views any Chinese space infrastructure outside Asia with increasing distrust. Beijing holds that its projects are purely scientific and accuses Washington of trying to contain its technological expansion. But for the United States, allowing China to gain strategic positions in Latin America means accept a presence potentially permanent technology in a region historically considered sensitive to American security. The shadow of the Chinese base. Impossible to ignore it. The Chinese space station built in Neuquén in 2015 It remains the great precedent that conditions everything else. The facility operates on land donated free of charge for fifty years and is managed by organizations linked to the Chinese space program. Officially it is a civilian base for space exploration, but in the United States there has always been suspicion of possible military or intelligence uses. That enormous antenna erected in the middle of Patagonia became for many American sectors the symbol of how China was beginning to consolidate a strategic presence in the Western Hemisphere through investments, infrastructure and technological cooperation. Scientists caught up in geopolitics. It is the other leg of the situation. One of the most striking aspects is how this rivalry has ended up directly affecting to scientists and universities. Astronomers accustomed to collaborating internationally suddenly found themselves caught up in debates about national security, espionage, and strategic competition. Some Argentine researchers were even invited by the United States to specific programs on risks associated with civil space infrastructures. For many, the feeling is that space has ceased to be relatively neutral terrain and has become part of the confrontation between powers. Cold War looking at the sky. If you also want, what is happening in South America reflects a much deeper change in the global competition between the United States and China. The rivalry no longer depends only on military bases or aircraft carriers. It is also played in data networks, submarine cables, artificial intelligence, space stations and astronomical observatories. Thus, under the skies of the Atacama or the Andes, a silent battle for technological control and strategic access to space. And precisely therein lies the paradox: because they are telescopes designed to observe the universe that have ended up becoming pieces of a new terrestrial Cold War.

How the Atacama desert shows the ecological price of decarbonization

Lithium has become white gold. Has become A strategic element Due to its importance in the global energy transition. Among other things, and While we find alternativesis what allows us to create batteries for electronic devices, but also critical systems for the decarbonization such as electric car batteries and those of renewable energy storage. There is a problem: extracting it requires huge amounts of water. Chile has one of the greater lithium reserves in the worldand its exploitation shows us the hidden cost of the energy that wants to “save” the planet. Atacama. The Atacama desert, located in northern Chile, is very peculiar. It is about driest desert in the worldbeing 250 more arid than the Sahara. It is a gigantic garbage dump Due to the fast fashion culture, but it also has huge solar parks that are the country’s energy pride: 500 operational projects and another hundred under construction. In addition to sun, there are minerals like copper –that China is accumulating at pleasure-, iron, gold and silver, but also other strategic such as Boto or Lithium. Within the region, the Salar de Atacama stands out. It is this area that has large lithium concentrations that have allowed Chile to become the largest global exporter of this element during the last two decades. It is so important that the Chilean regulatory regime gives the State property over lithium, considering it “Non -concessionable” and restricting foreign exploitation only to special contracts. Salar in 1995 In 2005 And today Ecosystem transformation. In the superior images we can see how the landscape of Salar has been transformed from 1990 to the present, with Lithium farms Greater and bigger. And something that we can see with the naked eye is the amount of huge ‘swimming pools’. The process of obtaining lithium is based on the evaporation of brine, being something that consumes billions of liters every year that is extracted from both the surface and the subsoil. In Atacama Salar, that is causing sinking, Loss of vegetation and of the rich microscopic diversityas well as the emblematic fauna of the place: the flamenco. Faviola González, biologist of the Chilean National Reserve, is one of those who complaint that the population of flamenco has decreased in recent years. It is not just your observation. As we read in the BBC article, the Natural Resources Defense Council, based in the United States, published a report in 2022 in which it indicated that almost a third of the native Algarrobos began to die in 2013 due to the impact of mining. Without brake. This transformation of the landscape has led to judicial demands, especially by indigenous communities that denounce the degradation of water resources and the loss of cultural identity of the desert. Because yes, Atacama’s is a desert, but with great biological wealth. The problem is the aforementioned Importance of lithium for the country. Chile is within the so -called ‘Lithium Triangle’ with Bolivia and Argentina and, as the second largest world producer and holder Of the largest reserves on the planet, it has the power to dominate the supply chain. It is an economic engine, with a value My dear of exports of 2,895 million in 2024, and its importance will go more. HE wait That the global lithium demand exceeds 1.3 million tons in 2025, with the forecast to triple by 2040. Measures to mitigate damage. And here comes the big question: if the lithium is needed to decarbonize the planet, but at the same time we are damaging the ecosystems in their obtaining, is there nothing we can make? Valentí Barrera, SQM Lithiuum Sustainability (the Chilean company that manages some of these farms) affirms that understand the concerns of indigenous communities and are carrying out pilot programs to mitigate the impact of mining. One is the Lithium extraction directly from brinewithout the need for evaporation pools. Another is the reinjection of water on earth once the lithium is obtained. The problem is that they are arguments that do not convince those who live from that land, who have seen the ecosystem disappear and who They affirm that they do not have a significant carbon footprint and that electric cars will go to Europeans and American, but contaminated water will be left. Because at some point, lithium will run out and the miners will leave. EITHER The price will fall so much which will cease to be profitable to extract it to Mansalva.

The Atacama desert is one of the most arid places on the planet. And right there a handful of “crazy” is trying to get water out of the fog

The oceans and seas house, According to estimates Used by the United States Geological Service (USGS), more than 96.5% of the water on our planet. In contrast, The atmosphere contains A modest 0.001% of this total. The clouds, fog and moisture of the air itself contains somewhat less than 13,000 cubic kilometers that also represent 0.04% of the planet’s fresh water. But in contexts in which the drought squeezes, each drop can count. Collecting water from the fog. A group of researchers He has successfully tested A method to obtain water from the fog. The system was able to collect between 0.2 and 5 liters of water per square meter and day. Secarral To test the method, the team responsible for the analysis resorted to the Municicpio of Alto Hospicio, located in the Atacama desert. This desert houses some of the most arid areas on the planet, in which rainfall barely reaches the annual millimeter. The city depends for its supply of the water contained in underground aquifers, but According to the team itselfthese have not been duly recharged in a period of between 10,000 and 17,000 years. The city extends rapidly and fruit of it around 10,000 of its residents live in informal settlements, almost all of them disconnected from the water supply system. “The collection and use of water, especially unconventional sources such as fog water, represents a key opportunity to improve the quality of life of the inhabitants,” explained in a press release Virginia Carter Hamberini, co -author of the study. A “new” method … A study that managed to show the potential of this technology. The team tested these mechanisms in the surroundings of the city of Alto Hospicio for a year, obtaining between 0.2 and 5 liters per square meter and day. Between August and September 2024, during the season of greatest activity, it was possible to reach up to 10 liters per square meter and day. “This research represents a notorious change in the perception of the use of water from fog, from a rural and rather small -scale solution to a practical water source for cities,” adds Carter Humberini. “Our findings show that fog can serve as a complementary source of urban water in dry areas where climate change exacerbates water deficiencies” The mechanism also has its limitations, they clarify. One of them is that its use is limited to high elevations outside the city limits. … that is not so new. The collection of fog water is not something novel, as Carter Haberini recalls, but it can be a convenient method to be climbed in a context like the present. The Fog Water Collection Appliancessuch as the one used in the study, they consist of a network through which the air loaded with moisture circulates. Part of that moisture is coupled to the fibers of the network and falls through them to a channel that leads to a deposit. The water of the deposit can thus be used in a variety of uses such as human consumption or agriculture. The details of the experiment were published In an article In the magazine Frontiers in Environmental Science. Learning lessons. The viability of fog water collection depends on the geographical characteristics of the environment: both climate and orography can affect the ability of this mechanism to provide water. These favorable conditions can occur in some areas of Spain, where already There are those who consider similar projects.
