The frontier has been an enduring mythical structure in American history and discourse and is often applied to rhetorics surrounding American space exploration. This project identifies shifts in the frontier myth in discourse surrounding growing attempts to land a human on Mars and uses Dr. Neil deGrasse Tyson, Elon Musk, and President Barack Obama as case studies. They are placed within G. Thomas Goodnight's argumentative spheres: the personal, the technical, and the public, respectively. Constrained by their sphere of discourse, each rhetor uses the frontier to transition from Aristotelian endoxa to social knowledge and consensus in specific ways.
