"Mission
to Mars: The Search for Water"
Abstract
"Follow
the Water!" is the mantra guiding the search for present-day or fossil
life on Mars, elsewhere in the solar system,
and
beyond. In my talk I will focus on two interrelated questions. Does
liquid water, a necessary condition for life
(as
we know it), presently exist at or near the Martian surface? Did Mars sustain
a prolonged ocean environment in its
ancient
past?I will review recent results from NASA's Mars Global Surveyor mission
which directly address these questions,
and
which have revolutionized our picture of Martian geology and climatic evolution.
