Environment Atmospheric pollution caused by space junk could be a huge problem Alec Luhn A SPACEX rocket that burned up after re-entering the atmosphere unleashed a plume of vaporised metals over Europe, a type of pollution that is expected to increase as spacecraft and satellites multiply. Vaporised aluminium reacts with atmospheric oxygen to form particles of aluminium oxide, which provide a surface where chlorine compounds can more easily break down. The chlorine radicals freed by this process react with and destroy ozone molecules in the stratosphere. of satellites, like SpaceX’s Starlink and Amazon’s Leo. …
