We discuss how visions for the futures of humanity in space and SETI are intertwined, and are shaped by prior work in the fields and by science fiction. This appears in the language used in the fields, and in the sometimes implicit assumptions made in discussions of them. We give examples from articulations of the so-called Fermi Paradox, discussions of the settlement of the Solar System (in the near future) and the Galaxy (in the far future), and METI. We argue that science fiction, especially the campy variety, is a significant contributor to the "giggle factor" that hinders serious discussion and funding for SETI and Solar System settlement projects. We argue that humanity's long-term future in space will be shaped by our short-term visions for who goes there and how. Because of the way they entered the fields, we recommend avoiding the term "colony" and its cognates when discussing the settlement of space, as well as other terms with similar pedigrees. We offer examples of science fiction and other writing that broaden and challenge our visions of human futures in space and SETI. In an appendix, we use an analogy with 1 the well-funded and relatively uncontroversial searches for the dark matter particle to argue that SETI's lack of funding in the national science portfolio is primarily a problem of perception, not inherent merit.Keywords: SETI -science fiction -human spaceflight -colonialism -futures
Visions of SETI and Human SpaceflightThe topics of SETI, human spaceflight, and humanity's long-term futures are intertwined. As we engage with outer space we bring history and culture with us and it becomes a "cultural landscape" (Gorman, 2009), a place that shapes and is in turn shaped by culture. Steven J. Dick 1 has called for a "systematic approach" applying anthropology to SETI and finds evidence in historical collaborations that this would be beneficial to both fields (Dick, 2006). As a collaboration between an astronomer and an anthropologist, this paper draws on both interdisciplinary SETI work and anthropology to discuss factors shaping the cultural landscapes of space with special attention to ways we imagine and talk about possible futures through science fiction.Human spaceflight, extraterrestrial intelligence, and the distant future are commonly completely blended in science fiction. Visions of humans traveling among the stars and encountering alien life are perhaps the quintessential science fiction trope. At first glance, it would seem that the endeavors of SETI and human spaceflight are generally more separated than this: the former has historically comprised relatively small, mostly privately-funded efforts concentrated among radio astronomers and a few others; the latter has comprised major governmental efforts by the United States, the former Soviet Union, Russia, and their partner nations for decades.
2Here we consider the more ambitious projects for human spaceflight of the sort aspired to by many governments but never (so far) seriously attempted: the permanent settlement of the So...
