Exploring Environmental History

Since the early days of the Space Age spent rocket stages, decommissioned satellites, and rubbish of all kinds have contaminated near-Earth space. At present more than 100 million pieces of human-made debris ranging in size from dead satellites to flecks of paint whiz around the Earth at incredibly fast speeds. This cloud of space junk poses a threat to our space infrastructure on which we now depend so much for navigation, communication, Earth surveillance, and scientific and industrial data collection, because even small fragments of a disintegrated spacecraft can seriously damage other satellites.

Does the creation of space debris mean that humanity has extended the “industrial sphere” into near-Earth space? Historian Lisa Ruth Rand, A PhD candidate at the University of Pennsylvania, discusses this question on episode 67 of Exploring Environmental History. She also examines why environmental historians should study the expansion of humanity beyond earth and other space environmental history related issues.
