Future SpaceMore than one hundred million pieces of human-made space debris currently orbit our planet, most moving at more than 10,000 mph. Every year their number increases, creating a progressively more dangerous environment for working spacecraft. In order to operate in space, we track most of this debris through a patchwork of private efforts and government defense networks. Creon Levit will discuss the history of space debris, the way the debris is currently tracked, and how we might work to reduce it before we see a cascading effect of ballistic interactions that could render low orbit all but unusable.
