Creon Levit
Space Debris and The Kessler Syndrome
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. In his Long Now Talk, Levit discusses 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.
