No TV, no sat nav, no internet: how to fix space's junk problem
As Elon Musk's Starlink and Jeff Bezos's Project Kuiper race to create high-speed internet using satellites orbiting Earth, there's a small problem that could get in the way: debris. From dead spacecraft that have been around since the dawn of the space age to flecks of paint smashing windows on the International Space Station, rubbish is clogging up our orbits. And with objects moving as fast as 15,500mph (25,000 kmph), the satellite services we've come to depend on are at constant risk of collision. So how to fix the problem with junk in space? Ian Anderson investigates.
