## Courses of Study

**[PH120] Space ... The Final Frontier**This writing-intensive course will use the exploration of other worlds, real and imagined, as an opportunity to investigate the shifting relationships between science, science fiction, and fantasy. Students will consider the social and political implications of human exploration, together with the science behind space travel and the historical development of the NASA space program in particular. Literature and films will be treated as texts, illustrating key elements of written craftsmanship such as word choice, style, structure, and narrative.
