Over the past 50 years there have been six astronomy surveys, two each for planetary science and for solar and space physics, and one each for Earth science and applications from space and for life and physical sciences research in space. 1 The NASA Authorization Acts of 2005 and 2008 provided a formal legislative mandate for decadal surveys in each NASA science area.

On the other hand, the survey committee forms the principal interface between the survey and its sponsoring agencies and organizations. The number of panels and their thematic orientation is perhaps the most obvious dissimilarity between the four recent decadal surveys.

Study Process Schematic timelines illustrating the high-level features of the study process employed by the four most recent decadal surveys sponsored by NASA SMD are illustrated in Figures 2.5 through 2.8. Activities common to most, if not all, of the most recent surveys include the following: • Alternating meetings of the survey committees and their supporting panels.

Mission designers at several NASA centers did assist the survey committee to determine the likely costs of key components -- e.g., instruments, spacecraft buses, launch vehicles and ground systems -- of mission concepts devised by the supporting panels. However, these activities nowhere near matched the scope of the studies conducted prior to or within the context of the three other recent decadal surveys.
