Here on Earth, the satellites that make up Starlink look like a string of stars travelling across the night sky. More than 4,000 of them are circling the Earth in low orbit right now. They’re part of the private venture that’s the brainchild of billionaire and SpaceX founder Elon Musk. Last year, when Russia invaded Ukraine, Musk sent Starlink terminals there so Ukraine could stay connected to the internet. But turns out Musk controls both the on and the off switch on that technology, giving him an outsized role in the conflict, according to Steven Feldstein of the Carnegie Endowment for International Peace. He’s out with a story in The Atlantic on how that happened and what can be done about it.
