Achieving a balance - Science and human exploration

The linkage between science and human exploration is close. Currently, proponents of science and human presence themes identified by the Synthesis Group as the most important themes of Mars exploration, tend to have reservations about the other camp. Mechanisms that integrate the program themes are essential, to gain the advocacies of the exploration communities and find optimal solutions to the technical problems. Without such mechanisms, it will be difficult to gain widespread acceptance of the SEI as the strategic horizon for the U.S. civilian space program.
