Unformatted text preview: Overview of NASA s Astrobiology Program by Michael Meyer (Mars Program Scientist NASA Headqtrs) Astrobiology is a key cross-theme element of both the Origins and Solar System Exploration programs of NASA: Astrobiology addresses concerns of major impact to Origins mission design Determine what makes a planet habitable and how common these worlds are in the universe. Determine how to recognize the signature of life on other worlds. Astrobiology represents a major, unifying scientiFc goal for Solar System exploration Determine whether there is (or once was) life elsewhere in our solar system, particularly on Mars and Europa. * Astrobiology Roadmap How life arose on the Earth Organization of matter into living systems How life evolves Co-evolution of biosphere and Earth Sources of organics on Earth. Origin of life ! s cellular components Models for life Genomic clues to evolution Linking planetary and biological evolution Microbial ecology Limits for life Character and frequency of habitable planets Signatures of life on other worlds Past or present life in the solar system Extremes of life Past and present life on Mars Life ! s precursors and habitats in outer solar system Natural migration of life Origins of habitable planets Effects of climate and geology on habitability Extrasolar biomarkers Is there life elsewhere in the universe?
