The Committee on Planetary and Lunar Exploration (COMPLEX) of the National Research Council's Space Studies Board (SSB) provides advice to the U.S. federal government on solar system research. Over the past 20 years, COMPLEX has developed scientific strategies for the investigation of the inner solar system, the outer solar system, primitive bodies, and other solar systems.
COMPLEX has been asked by the SSB to establish overall priorities for the exploration of the solar system throughout the next decade. COMPLEX will subdivide solar system science into five disciplines: solid bodies, atmospheres, rings and dust, and origins including meteorites, extra-solar planetary systems, and theoretical modeling. In these areas, and across solar system science as a whole, we will summarize our current understanding, pose the most significant questions yet to be answered, and establish priorities for research.
