Elon Musk and his SpaceX team want to launch up to one million satellites as part of a proposal to power massive data centres in space.

They pitch it as a clean, green alternative to regular data centres. But as Earth’s orbit becomes increasingly crowded, what will Elon’s mega constellation do to our night sky? And could a crash between satellites set off a catastrophic chain reaction?
