Space Explosions - What Can We Do About It?

More 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 spent over three decades at NASA, and is now the Director of R&D at Planet, a company that is imaging the earth everyday with one of the largest swarms of micro-satellites in the world. Creon 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.
