Some 600km above Earth is a rapidly intensifying cloud of satellites. They’re already indispensable. They enable our smartphones to navigate, research, and think for us. They control remote-controlled farming and mining machinery. They watch the ground to analyse everything from bugs to floods.Which is why megacorporations like Elon Musk’s SpaceX and superpowers like China are determined to pump tens of thousands more of these metallic boxes into increasingly crowded space lanes. Unlike cars and trucks, an orbital accident doesn’t end with the initial pile-up. The wreckage keeps flying. And one prang can cause tens of thousands of others. Do you think that the number os satellites on space should be regulated urgently ?
