In the 1950s, a combination of technological and scientific advancement, political competition, and changes in popular opinion about spaceflight generated public policy in favor of an aggressive space program. This and that of 1960s moved forward with a Moon landing and the necessary budgets. Space exploration reached equilibrium in the 1970s, sustained through to the present. The twenty-first-century progresses signals that support for human space exploration is waning and may even begin declining in the coming years. This chapter reviews this history and analyzes five rationales suggested in support of continued human spaceflight: discovery and understanding, national defense, economic competitiveness, human destiny, and geopolitics.

Unfortunately, I am not the first to attempt to map out the narrative terrain of Others. In 1985, R. S. Perinbanayagam presented various social theorists’ conceptions of the Other in his book Signifying Acts: Structure and Meaning in Everyday Life. Basically, they comprise three Others: the Generalized Other, the Meiotic Other (my language), and the Significant Other. I will address three additional Others – the Unconscious Other, the Marginalized Other, and the Nonhuman Other – that I find in a broader and more recent literature. Although I group them into six main Others, the borders of these types are somewhat arbitrary, porous, and nondiscrete, as interaction and intersection exist among them. Two characteristics that distinguish one Other from another are whether the Other exists within or outside the Self and whether the Other is an individual or aggregate entity. The Unconscious Other and the Generalized Other both are constructed from symbolic material outside the individual but ultimately take up residence within the Self. The Meiotic Self is the self-divided; there may be multiple divisions but each Meiotic Self is usually presented as singly constituted. The Significant Other, an individual, and the Marginalized Other, often a status group or member of it, reside outside the Self but play supporting roles in relation to any particular Self, which may also be an individual or status group, such as men, Whites, and Americans. The Nonhuman Other may be individual, an aggregate of individuals, or the product of human behavior, all of which reside outside the Self.
