The American astronaut image was informed by early Cold War ideals of masculinity that helped mold a distinctly American (anti-communist) masculinity, which appeared―on the surface anyway―to resolve not only an American “crisis of masculinity” but helped win the Cold War on an ideological and popular level. This American image focused on strict gender binaries of man as the protector, controlling technology and containing communism, while woman was the passive actor with spaceflight technology―left behind in the home waiting for the return of the astronaut husband. Allowing women to fly into space would have represented a lack of individual control with spaceflight technology.  “McComb explores the construction of a masculine U.S. astronaut image based on rugged individuali-ty, self-determination and control as a Cold War counter to Soviet collectivism, even as NASA straddled conservative and progressive understandings of gender roles by allowing women to hold traditionally male jobs as engineers, computer programmers and technicians.” ― Alan D. Meyer , author of Week-end Pilots: Technology, Masculinity, and Private Aviation in Postwar America (2015). “McComb sheds new light on the storied space race and its aftermath through a sharp focus on gender and astronauts. Her historical scholarship traces in vivid detail how a culture of masculinity was estab-lished within U.S. aerospace but challenged by daring women including Jerrie Cobb, Sally Ride and Ei-leen Collins .” ― Jordan Bimm, University of Chicago, US “McComb offers a fresh perspective on how women were publicly accepted as members of the astro-naut corps. Accordingly, technological changes that shifted spaceflight from being viewed as a dan-gerous endeavor to a routine one markedly changed perceptions of who could participate in space-flight.” ― Monique Laney, Auburn University, USA “This exhaustively researched book, prepared by an experienced space studies scholar, is likely to be received enthusiastically by historians of technology, women’s and gender studies scholars, and space history enthusiasts.” ― Matthew H.
