Goal 3: Determine how the long-term evolution of Mars affected the physical and chemical
environment critical to habitability and the possible emergence of life.
- Primary Objective Characterize organic chemistry and co-occurring concentrations of
bioessential elements, including stable isotopic composition and stereochemistry. Analyses
might include but should not be limited to known molecular markers of terrestrial life, such
as membrane lipids, proteins, nucleic acid polymers, and complex carbohydrates.
Goal 1: Characterize past habitability and search for evidence of ancient life
- Secondary Objective Search for evidence of ancient life in environments having high
combined potential for prior habitability and preservation of biosignatures (as determined by
A.1 and A.2).

- use MEPAG
- This section should also define the overall geographic and/or geological focus of the
mission and attempt to tie this into the landing site decision. For example, if you select
volcanism as a mission focus, choosing an area like the North Polar Cap that has no
evidence for volcanism would be difficult to justify. Provide references to peer-reviewed
literature where appropriate.
