In the 1970s, Gerard O’Neill drew up detailed plans for large space colonies. The Princeton physicist claimed that these colonies could beam limitless energy back down to Earth, solving all our environmental problems. As climate change accelerates, O’Neill’s once-forgotten green dream has become influential again; many of today’s corporate space evangelists refer to themselves as “Jerry’s Kids.” For solutions to Earth’s problems, should we look to the stars?

Plus, in the back half, we talk to Mary-Jane Rubenstein about the religious and colonial language of the early space evangelists, and why that language persists into the present day.

This is the first episode of our new season, Green Dreams. In Green Dreams, we tell stories of radical environmental thinkers and their dreams for our green future. Should we make those dreams reality, or are they actually nightmares? For a full list of credits, and for the rest of the episodes, visit the series page.
