Exo-astrobiology with ESA space science missions

Key questions of astrobiology can be addressed by several space missions from the ESA Science Horizons 2000 Programme, such as: - How do solar and stellar systems form ? (with ISO, FIRST, SMART-1, Rosetta, Colombo, Gaia) - Geological evolution of terrestrial planets (with Living planet, Mars-express, SMART-1, Bepi-Colombo to Mercury) - Interstellar Complex organic chemistry (with ISO, ISS/EXPOSE, FIRST, Rosetta) - Co-evolution of Earth-Moon, impacts life frustration (with SMART-1, Bepi-Colombo) - How to detect other solar systems and habitable zones (with space photometry, COROT, Eddington, Gaia, IRSI-Darwin) - Early Earth and alternative environments (Huygens/Cassini and Mars-express) - Signature of biosphere, global biomarkers and photosynthesis evolution (living Planet missions, Darwin) - Water and exobiology on Mars (with orbiter instruments and Beagle-2 lander on Mars Express) - Study of biomarkers and delivery of organics (with Mars-express and future missions) We shall review the Exo-Astrobiology potential from these ESA missions.
