Why do we explore space? This is not an easy question to answer. Yet policy expert G. Ryan Faith believes there is value to be had in communal engagement with this question. While easy answers may elude us, the act of defining our values and goals in space can help avoid common pitfalls and dead ends in our exploration efforts, ensuring a continued commitment to space for generations to come. Disc...
