abstract |
Fluvial features and evidence for aqueous alteration indicate that Mars was wet, at
least partially and/or periodically, in the Noachian. Also, impact cratering appears
to have been the dominant geological process during that epoch. Thus, investigation
of Noachian craters will further our understanding of this geologic process, its effects
on the water-bearing Martian crust, and any life that may have been present at the
time. Impact events disturbed and heated the water- and/or ice-bearing crust, likely
initiated long-lived hydrothermal systems, and formed crater lakes, creating environments
suitable for life. Thus, Noachian impact craters are particularly important exploration
targets because they provide a window into warm, water-rich environments of the past
which were possibly conducive to life. In addition to the presence of lake deposits,
assessment of the presence of hydrothermal deposits in the walls, floors and uplifts
of craters is important in the search for life on Mars. Impact craters are also important
for astrobiological exploration in other ways. For example, smaller craters can be
used as natural excavation pits, and so can provide information and samples that would
otherwise be inaccessible. In addition, larger (> ~75 km) craters can excavate material
from a potentially habitable region, even on present-day Mars, located beneath a >5-km
deep cryosphere. |
