Samsung Galaxy Unpacked 2026 is Feb. 25 A single collision could cause a cascading effect in orbit. Elon Musk's plan to launch millions of AI satellites could be disastrous for the planet. At the start of the month, Elon Musk announced that two of his companies -- SpaceX and xAI -- were merging, and would jointly launch a constellation of 1 million satellites to operate as orbital data centers. Musk's reputation might suggest otherwise, but according to experts, such a plan isn't a complete fantasy. However, if executed at the scale suggested, some of them believe it would have devastating effects on the environment and the sustainability of low Earth Earth orbit.

When a SpaceX rocket failure set the skies aflame over western Europe last February, no-one was sure if the debris was also polluting our atmosphere. Now scientists are directly linking the uncontrolled rocket re-entry to a plume of lithium measured less than 100km above Earth. It is the first time researchers have drawn a direct link between a known piece of space debris crashing to Earth and pollution levels. They warn that as SpaceX chief Elon Musk pledges to launch one million satellites in the coming years, this contamination could be the tip of the iceberg. The scientists were already investigating the problem of pollution from space debris when they realised a SpaceX Falcon 9 had failed in flight.

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.

A key part of the SpaceX-xAI deal's rationale is to move datacentres - the central nervous system of AI tools - into space.

SpaceX's acquisition of xAI creates business worth $1.25tn but whether premise behind deal will work is questioned The acquisition of xAI by SpaceX is a typical Elon Musk deal: big numbers backed by big ambition. As well as extending "the light of consciousness to the stars", as Musk described it, the transaction creates a business worth $1.25tn (£920bn) by combining Musk's rocket company with his artificial intelligence startup.

While SpaceX is routinely described as being owned by Elon Musk, he is not the only person in the capsule. While SpaceX is routinely described as being owned by Elon Musk, he is not the only person in the capsule. Elon Musk is taking SpaceX's minority shareholders for a ride T o Elon Musk's fanclub, there is nothing to see apart from more evidence of the great man's visionary genius. SpaceX, the rocket firm, is buying xAI, the artificial intelligence developer, and the combination of these two Musk-controlled entities is being valued at $1.25tn (£910bn). Or, as Musk described it, he is creating "the most ambitious, vertically integrated innovation engine on (and off) Earth, with AI, rockets, space-based internet, direct-to-mobile device communications and the world's foremost real-time information and free-speech platform".

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.

In a pine forest on Michigan's Upper Peninsula, the only active nickel mine in the US is nearing the end of its life. At a time when carmakers want the metal for electric-vehicle batteries, nickel concentration at Eagle Mine is falling and could soon drop too low to warrant digging. Demand for nickel, copper, and rare earth elements is rapidly increasing amid the explosive growth of metal-intensive data centers, electric cars, and renewable energy projects. But producing these metals is becoming harder and more expensive because miners have already exploited the best resources. Here's how biotechnology could help . What we've been getting wrong about AI's truth crisis What would it take to convince you that the era of truth decay we were long warned about--where AI content dupes us, shapes our beliefs even when we catch the lie, and erodes societal trust in the process--is now here?

The Morning After: Elon Musk's SpaceX is buying his AI company, xAI Like some sort of corporate Russian doll, SpaceX has announced its acquisition of xAI. The merger will "form the most ambitious, vertically integrated innovation engine on (and off) Earth," according to, well, owner Elon Musk. The AI company, arguably best known for its ongoing CSAM-generating chatbot controversy, might seem like a strange fit for a rocket company. But SpaceX is apparently key to Musk's latest scheme to build AI data centers in space. There might be an argument for moving the resource-intensive operations to space -- but Musk continued.

Elon Musk's SpaceX is already one of the world's most valuable private companies. Elon Musk's SpaceX is already one of the world's most valuable private companies. Aerospace business and artificial intelligence firm to unite for IPO as world's most valuable private company Elon Musk's aerospace company SpaceX has acquired his artificial intelligence business xAI, in a $1.25tn (£910bn) merger that consolidates part of Musk's empire as SpaceX prepares to go public later this year. The two companies announced the deal on Monday in a statement on SpaceX's website, saying the merger would form "the most ambitious, vertically-integrated innovation engine on (and off) Earth, with AI, rockets, space-based internet, direct-to-mobile device communications and the world's foremost real-time information and free speech platform". SpaceX, one of the world's most valuable private companies, will gain xAI properties such as its Grok chatbot and the social media platform X.

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.
