Cleaning Up Space

#S02E03 - Cleaning Up Space

Ever since humans started sending satellites into space we've always neglected one very big issue - what happens when these man-made objects reach the end of their useful life? Some of the satellites will fall out of orbit, but many have remained in space for decades with no clear strategy of what to do with them. But as humans look to explore commercial space flight and populate other planets there's a growing concern that all of this space junk could pose a very real threat to our future space endeavours. So how do we actually go about cleaning up space?
