After a Falcon 9 rocket stage burned up in the atmosphere, vaporised lithium and other metals drifted over Europe. A SpaceX rocket that burned up after re-entering the atmosphere unleashed a plume of vaporised metals over Europe, a type of pollution that is expected to increase as spacecraft and satellites multiply. The upper stage of a Falcon 9, which is designed to splash down in the Pacific Ocean for possible re-use, lost control due to engine failure and fell from orbit over the north Atlantic in February 2025. We're finally solving the puzzle of how clouds will affect our climate People across Europe saw fiery debris streaking through the sky, some of which crashed behind a warehouse in Poland. Seeing the news, Robin Wing at the Leibniz Institute of Atmospheric Physics in Germany and his colleagues turned on their lidar, an instrument for atmospheric sensing.

MPs fear data centre boom could derail Miliband's net zero plans Ed Miliband has been urged to explain whether a planned boom in energy-hungry data centres have been factored into his plans to deliver net zero carbon emissions. In a letter to the energy secretary, Labour MP Toby Perkins, who chairs the Environmental Audit Committee, said data centres are a key area of concern in hitting the emissions target. Data centres are giant facilities full of powerful computers used to run digital services, such as streaming and artificial intelligence (AI). The government has backed plans for many more to be built to help turn the UK into an AI superpower, despite the large amounts of electricity needed to run them, including from gas-powered generators. Perkins said it was concerning that the UK government was relying on a carbon-reduction plan that made no allowance for the impact of data centres.

Why did SpaceX just apply to launch 1 million satellites? We are only a month into 2026, yet it's already clear what one of the major space stories of the year is going to be: mega-constellations, and the ongoing attempts to launch thousands of satellites into Earth's orbit. The latest development is that SpaceX has asked the US Federal Communications Commission (FCC) for permission to launch 1 million orbital data centre satellites. The previous largest filing with the FCC, also by SpaceX, was for 42,000 Starlink satellites in 2019. "This is beyond what's been proposed by any constellation," says Victoria Samson at the Secure World Foundation in the US.

Elon Musk's SpaceX has acquired his AI company xAI as part of an ambitious scheme to build space-based data centres to power the future of artificial intelligence. The billionaire, who is also the CEO of Tesla, announced the merger in a statement on Tuesday on the SpaceX website. AI demand will require "immense amounts of power and cooling" that are not sustainable on Earth without "imposing hardship on communities and the environment," he said. Space-based data centres that harness the power of the Sun are the only long-term solution, according to Musk. "In the long term, space-based AI is obviously the only way to scale. To harness even a millionth of our Sun's energy would require over a million times more energy than our civilisation currently uses!" he wrote.

Elon Musk - the boss of SpaceX as well as Tesla and X - is the world's richest person Elon Musk's SpaceX has applied to launch one million satellites into Earth's orbit to power artificial intelligence (AI). The application claims "orbital data centres" are the most cost and energy-efficient way to meet the growing demand for AI computing power. Traditionally, such centres are large warehouses full of powerful computers which process and store data. Musk's aerospace firm claims processing needs due to the expanding use of AI are already outpacing "terrestrial capabilities". It would increase the number of SpaceX satellites in orbit drastically.

Elon Musk is making a big bet on his future vision - will it work? Reports suggest that Elon Musk is eyeing up a merger involving SpaceX, Tesla and xAI, but what does he hope to achieve by consolidating his business empire? Elon Musk is a busy man, heading up multiple billion-dollar companies. While he is increasingly a divisive figure, there is no doubt that Tesla and SpaceX, his two most important ventures, have done much to advance the future of electric cars and spacecraft, respectively. But a series of corporate moves this week suggests Musk has a new vision of the future - and he may be combining all his companies to get there.

AI's growing thirst for water is becoming a public health risk "Bubble" is probably the word most associated with "AI" right now, though we are slowly understanding that it is not just an economic time bomb; it also carries significant public health risks. Beyond the release of pollutants, the massive need for clean water by AI data centres can reduce sanitation and exacerbate gastrointestinal illness in nearby communities, placing additional strain on local health infrastructure. AI's energy consumption is massive and increasingly water-dependent Generative AI is artificial intelligence that is able to generate new text, photos, code and more, and it has already infiltrated the lives of most people around the globe. ChatGPT alone is reported to receive around one billion queries in a single day, pointing to huge demand at the individual level. This, however, is only the tip of the iceberg.

US approves sale of Nvidia's advanced AI chips to China The US government has given chip giant Nvidia the green light to sell its advanced artificial intelligence (AI) processors in China, the Department of Commerce said on Tuesday. The H200, Nvidia's second-most-advanced semiconductor, had been restricted by Washington over concerns that it would give China's technology industry and military an edge over the US. The Commerce Department said the chips can be shipped to China granted that there is sufficient supply of the processors in the US. President Donald Trump said last month that he would allow the chip sales to approved customers in China and collect a 25% fee. Nvidia's spokesperson told the BBC that the company welcomed the move, saying it will benefit manufacturing and jobs in the US.

They work 24/7 at high speeds and get searingly hot - but data centre computer chips get plenty of pampering. Some of them basically live at the spa. We'll have fluid that comes up and [then] shower down, or trickle down, onto a component, says Jonathan Ballon, chief executive at liquid cooling firm Iceotope. Some things will get sprayed. In other cases, the industrious gizmos recline in circulating baths of fluid, which ferries away the heat they generate, enabling them to function at very high speeds, known as overclocking.

Putting data centres in space isn't going to happen any time soon Could AI's insatiable thirst for colossal data centres be fixed by launching them into space? Tech companies are eyeing low Earth orbit as a potential solution, but researchers say it's unlikely in the near future due to a mountain of difficult and unsolved engineering issues. The huge demand for, and investment in, generative AI products like ChatGPT has created an unprecedented need for computing power, which requires both vast amounts of space and gigawatts of power, equivalent to that used by millions of homes. As a result, data centres are increasingly fuelled by unsustainable sources, like natural gas, with tech companies arguing that renewable power can neither produce the amount of power needed nor the consistency required for reliable use. To solve this, tech CEOs like Elon Musk and Jeff Bezos have suggested launching data centres into orbit, where they could be powered by solar panels with constant access to a higher level of sunlight than on Earth.
