Trash isn't just a problem on the surface of Earth — it also poses a danger for the communications and scientific infrastructure that we rely on in space. 60 years of launching things into orbit have created a huge amount of space junk that can destroy satellites, even at sizes as small as a pea. With the problem of space junk growing exponentially, some novel solutions have been proposed, from nets and harpoons to repelling magnets and lasers.
Due to some recent breakthroughs, Elon Musk has upped the probability that he'll be on a rocket to Mars. The SpaceX CEO told Axios on HBO that there's now a 70% chance he'll reside on the Red Planet one day. He followed it up by shooting down the notion that a move to Mars is just an escape hatch for rich people by revealing the harsh realities that would come with the new zip code.
