In addition to a call for white papers that asked respondents to provide their ideas and thoughts on ensuring a sustainable human spaceflight program, a 1-day Twitter campaign sought the publicвЂ™s вЂњbest ideasвЂќ along the same lines. (Elsewhere in this report, the committee observes, for example, the prevalence of human spaceflight themes in movies, advertisements, and other media.)ДЄs part of its outreach effort, to cast the net as broadly as possible in examining a question that speaks as much to cultural and philosophical concerns as it does to practical benefits, the committee invited comments via social media. The committeeвЂ™s examination therefore included consideration of insights from a variety of avenues, including insights provided by popular culture. The cultural significance of human spaceflight resonates in many ways in society. Finally, as requested in the committeeвЂ™s charge, the combination of the rationales is addressed in the language of a value proposition, which provides an alternative way to express rationales for such a program.ДЄ difficult but inescapable challenge to the committeeвЂ™s work was the fact that much of the rationale for human spaceflight is difficult to evaluate with solely quantitative and analytic methods. engagement in a human spaceflight program rationales effectively define the goals and aspirations toward which such a program can contribute. That is followed by a discussion of the rationales that have historically been and still are advanced to justify U.S. It then elaborates on the considerations that led the committee to formulate the enduring questions presented in Chapter 1. First, it reports on and presents the results of two outreach efforts from the committee to communities interested in space to gather ideas and inputs that could help inform the committeeвЂ™s work: a call for white papers on topics related to the committeeвЂ™s charge and a day of Twitter conversations (hashtag #HumansInSpace). This chapter contains three separate though inter-related pieces of work, responsive to various elements of the charge to this committee.
