Mars Exploration Program Analysis Group

The Mars Exploration Program Analysis Group advises National Aeronautics and Space Administration planning for robotic and human exploration of Mars (planet), coordinating scientific priorities among stakeholders including the Jet Propulsion Laboratory, NASA Ames Research Center, NASA Goddard Space Flight Center, NASA Johnson Space Center, and international partners such as the European Space Agency, Roscosmos, and Japan Aerospace Exploration Agency. It brings together researchers from institutions like the California Institute of Technology, Massachusetts Institute of Technology, University of Arizona, Arizona State University, and Smithsonian Institution to align mission concepts with recommendations from bodies including the National Academies of Sciences, Engineering, and Medicine, the U.S. Congress, and interagency panels such as the Planetary Science Decadal Survey.

History

Formed in 1995 in response to strategic reviews following the failures and successes of early Mars Observer and Mars Pathfinder-era projects, the group evolved alongside programs including Mars Global Surveyor, Mars Reconnaissance Orbiter, Mars Exploration Rovers Spirit and Opportunity, and Mars Science Laboratory (Curiosity). Members participated in evaluating mission outcomes from Viking program heritage, lessons from Mars Climate Orbiter and Beagle 2, and opportunities presented by discoveries at sites such as Gale Crater and Jezero Crater—the latter leading to Mars 2020 (Perseverance) selection. MEAPAG has interfaced with career milestones and policy shifts linked to administrations, congressional legislation like the NASA Authorization Act, and reports by panels such as the Space Studies Board.

Organization and Membership

The group comprises scientists and engineers drawn from universities, government laboratories, commercial firms, and international agencies: examples include Lockheed Martin, Northrop Grumman, SpaceX, Blue Origin, European Southern Observatory, and national space agencies like Canadian Space Agency. Leadership typically involves a chair and steering committee with representation from centers including NASA Jet Propulsion Laboratory and NASA Marshall Space Flight Center, as well as subject-focused working groups on topics such as astrobiology, geology, atmospheric science, and sample curation involving institutions like Smithsonian Institution National Museum of Natural History and Carnegie Institution for Science. Membership rosters have featured researchers affiliated with California Institute of Technology, Stanford University, University of Colorado Boulder, Cornell University, University of California, Los Angeles, University of California, Berkeley, Purdue University, University of Washington, University of Michigan, Imperial College London, and laboratories such as Lawrence Livermore National Laboratory and Los Alamos National Laboratory.

Objectives and Activities

MEAPAG’s objectives include prioritizing science goals consistent with the Planetary Science Decadal Survey and operational constraints of NASA Science Mission Directorate portfolios, coordinating community input for missions like Mars Sample Return, establishing science traceability matrices for instruments aboard platforms such as Perseverance (rover), InSight (spacecraft), and proposed concepts like Mars Ascent Vehicle, and addressing planetary protection requirements from organizations including the Committee on Space Research (COSPAR). Activities encompass organizing town halls at meetings of the American Geophysical Union, the Lunar and Planetary Science Conference, and the European Geosciences Union, producing white papers for calls from the Decadal Survey Committee, and facilitating cross-disciplinary research connecting experts in astrobiology from groups such as the NASA Astrobiology Institute and planetary geologists studying analogs at sites like Svalbard and Atacama Desert.

Major Reports and Recommendations

The group has produced influential community reports recommending priorities reflected in missions including Mars Reconnaissance Orbiter, Phoenix (spacecraft), Curiosity (rover), and Perseverance (rover), and has issued guidance on strategies for Mars Sample Return architecture, contamination control, and caching strategies that influenced partnerships with European Space Agency and proposals involving industrial partners such as Aerojet Rocketdyne. Reports have addressed objectives from identifying past habitability at sites like Gale Crater to recommending payloads for future landers and orbiters to detect organics, isotopic records, and sedimentary structures studied in work by investigators at Brown University, University of Texas at Austin, Montana State University, and Johns Hopkins University Applied Physics Laboratory.

Role in Mission Planning and Policy

MEAPAG informs NASA programmatic decisions by advising on science requirements, helping to translate priorities from the Decadal Survey into mission concepts evaluated by the NASA Advisory Council, and coordinating inputs to program offices responsible for solicitations such as Discovery Program and New Frontiers. The group’s recommendations intersect with policy forums including the National Academies Space Studies Board, regulatory frameworks influenced by the Outer Space Treaty, and implementation plans coordinated with agencies like the U.S. Geological Survey for landing site characterization and hazard assessment.

Collaboration and Outreach

The group fosters collaboration among international partners including European Space Agency, Roscosmos State Corporation for Space Activities, Indian Space Research Organisation, China National Space Administration, and Australian Space Agency, and engages the broader community through public sessions at conferences like the American Astronomical Society meetings and outreach collaborations with institutions such as the Smithsonian Institution and National Air and Space Museum. It supports early-career scientists via mentorship and workshops run with societies like the Geological Society of America, the American Association for the Advancement of Science, and the Planetary Society, and publishes community-position documents that inform educators, policymakers, and industry stakeholders including NASA Headquarters program managers.
