Could a $200K bond for satellites paid before launch prevent a space junk disaster in orbit? Here's why some scientists think so

The space around Earth is turning into a junkyard. Researchers think a refundable deposit scheme could force satellite operators to clean up their act before a tipping point is reached.For years, space sustainability experts have warned that the growing number of satellites in orbit and the quantity of dead metal left behind threatens to trigger a dangerous cascade of collisions known as the Kessler Syndrome. Predicted in the 1970s by NASA physicist Donald Kessler, this chain of orbital smashups
