The thousands of satellites and other low Earth orbiting objects are cause for concern i.e. they could interfere with other space flights. To counteract this problem, the Global Aerospace Corporation struck GOLD, or the Gossamer Orbit Lowering Device.
GOLD is a balloon which is affixed to a satellite and then inflated. It thereby causes the orbit to decay and the satellite to burn in the Earth’s atmosphere. I am not sure how big of a problem space junk is, or if this is a viable solution, but on the plus side there is finally a use for the leftover Rovers now that Number 6 drove off the island.
