Summary

ABSTRACT

A central goal in Mars exploration is to determine whether life has ever existed there and, whether it did or not, the degree to which the Mars environment could have sustained life. To attain this goal, we can characterize the environmental context, identify places most likely to have sustained life and retained evidence of its presence, and search for “biosignatures,” namely features created only by life and that can persist long after they were formed. Life as we know it requires liquid water, source(s) of energy to sustain metabolism, and chemical building blocks for its cellular constituents. The availability of liquid water appears to be the primary limiting factor in near-surface Martian environments. Liquid water apparently was more widespread on the surface in ancient times and it has occurred within the crust at various times. Oscillations in the orbital obliquity of Mars probably influenced the distribution of water, and some evidence hints of recent liquid water. Observations by the Mars Exploration Rover (MER) Spirit in Gusev crater are consistent with the possibility that liquid water, nutrients and sources of chemical energy were simultaneously available to sustain habitable conditions in subsurface Columbia Hills materials at least some time in the distant (Noachian?) past. As of this writing Spirit rover has not yet determined that these conditions ever existed in a surface environment. MER Opportunity revealed that habitable environments might have persisted for an extended period of time in the Meridiani Planum region at some time in the distant past.
