The PAC supports the advisory needs of the Planetary Science Division (PSD), the Science Mission Directorate (SMD) and other mission directorates as required, and NASA Administrator.  The scope of the PAC includes all aspects of planetary science, scientific exploration of the Moon and Mars, the robotic exploration of the solar system, astrobiology, exoplanet research, space- and ground-based research, technology development, planning, and training required to support these science areas.  In addition to scientific research, the scope encompasses considerations of the development of near-term enabling technologies, systems, and computing and information management capabilities, as well as developments with the potential to provide long-term improvements in future operational systems.  Responsibility for biological planetary protection is outside the purview of the PAC.
