Mega-constellations risk turning orbit into a debris nightmare

SpaceX’s Starlink mega-constellations now dominate low-Earth orbit with about 10,000 satellites and plans for up to a million more, sparking concerns over light pollution, future debris, and potential ground fallout; satellites typically burn up on re-entry, but larger mega-constellations could leave debris that falls to Earth, as seen in Saskatchewan, and Canada has no formal debris reporting or environmental regulation for space activities; experts warn of increased collision risk (Kessler syndrome) and stress the need for Canadian internet alternatives and stronger governance, since SpaceX currently controls a large share of orbital slots.
