Working Groups
NASA's Science Mission Directorate acquires community input, independent evaluation, and advice through three principal means. First, the various boards and committees of the National Research Council advise NASA on a variety of matters in science, applications, technology, and multi-program planning. Second, the NASA Advisory Council (NAC) advises us on program priorities and planning. Finally, the science community provides input to the Directorate in developing roadmaps for each science discipline area.
