The Mars Exploration Program Analysis Group (MEPAG) serves as a community-based, interdisciplinary forum for inquiry and analysis to support NASA Mars exploration objectives. MEPAG is responsible for providing the science input needed to plan and prioritize Mars exploration activities. To carry out its role, MEPAG organizes public meetings to gather information and conduct specific studies to address issues and analyze proposed future activities. Based on those activities, MEPAG documents goals, objectives, investigations, and required measurements for the robotic and human exploration of Mars. Updates in response to discoveries and community input are captured in the MEPAG "Goals Document". The four overarching MEPAG goals for the exploration of Mars and its moons are:
Goal 1. Determine if Mars ever supported life

Goal 2. Understand the processes and history of climate on Mars

Goal 3. Understand the origin and evolution of Mars as a geological system

Goal 4. Prepare for human exploration

The MEPAG Steering Committee provides overall leadership, supported by input from the broad Mars community and a MEPAG Goals Committee that maintains the MEPAG Goals Document. Both committees are described in more detail below. If you are interested in serving on either of these committees in the future, please email
MEPAG Steering Committee: The MEPAG Steering Committee (formerly called the Executive Committee) consists of the MEPAG Chair (lead), the previous MEPAG Chair, the Mars Exploration Program (MEP) Lead Scientist, the Mars Program Office Chief Scientist, the Goals Committee Chair, and up to 10 additional members of the MEPAG community. The HEOMD Chief Scientist for Exploration is an ex officio member. Amongst its duties, the Steering Committee organizes virtual and in-person meetings, choosing topics of interest to the community and soliciting reports from Planetary Science Division (PSD) and MEP for discussion. MEPAG may choose to organize Science Analysis Groups (SAGs) to deal with specific issues at the request of NASA or the general community. Results that emerge from SAG reports or findings in response to presentations and discussions at MEPAG meetings are posted to the community on the MEPAG website. Status reports are routinely made to MEP and the Planetary Science Advisory Committee (PAC).

MEPAG Goals Committee: The Goals Committee nominally has two members for each of the four-goal areas, in addition to its Chair. Membership of the Steering and Goals Committees is solicited from the MEPAG community and determined by the Chair and Steering Committee. Logistical and organizational support to the MEPAG, including its analysis groups, is provided by SMD/MEP through the Mars Program Office, located at the Jet Propulsion Laboratory.
