Look, @hkrag, you are on TV! #spacedebris
While we’ve been so focused on separating our cardboard and plastic down on Earth, waste, abandoned satellites, and other man made debris have been accumulating in space. If we want to continue our progress in space and maintain our technology, it’s time for a major cleanup!

If action is not taken soon, insurance premiums for satellites will rise, spending on tracking and collision-avoidance systems will have to increase, and certain orbits risk becoming unusable econ.st/2LL8oFj
