摘要:In August 2012, the National Research Council (NRC) of the U.S. National Academies issued the second-ever “decadal survey” for solar and space physics (Heliophysics). Sponsored by NASA and the National Science Foundation, and with the support of the relevant parts of NOAA and the Department of Defense, the survey effort was informed by some 300 white papers, dozens of town hall and community meetings, and the work, over an 18 month period, of 85 scientists who populated the Survey steering committee, three discipline-oriented study panels, and five cross-disciplinary working groups.
