Ethics are difficult on Earth. In outer space, the questions are even harder

Humans have gotten a lot wrong when it comes to living on Earth. And while it wouldn’t be possible to entirely leave earthly problems behind, when humans settle outer space there will be a host of ethical questions with which to grapple. At an event presented by Missouri Humanities and recorded at the James S. McDonnell Planetarium, Elaine Cha spoke with astrophysicist and author Erika Nesvold. Nesvold is the author of “Off-Earth. Ethical Questions and Quandaries for Living in Outer Space.”
