TPF Science Roadmap • Coordinated observing/theoretical program to address questions affecting TPF/Darwin architecture/scope • What is η ⊕ ? – Transits (MOST,COROT, Kepler/Eddington) – Theory extrapolating from gas giant statistics terrestrial planets • What is level of exo-zodiacal emission? – SIRTF (Kuiper belts @ 3-300 of AU) – Keck-I/LBT-I/VLT-I (Zodiacal clouds at ~0.3-3 AU) – Theory extrapolating from dust distribution terrestrial planets • What wavelength region should we observe? – Atmospheric and bio-markers from visible to mid-IR • What are physical properties of giant planets? – Advance understanding and demonstrate techniques • What controls orbital stability in region of habitable zone? – Are solar systems “dynamically full” with planets in all stable orbits? • What are properties of target stars – Activity, presence of giant planets, zodi disks, gal/x-gal backgrounds 5-10% of TPF budget will support scientific activities
Collaboration on TPF/Darwin • Strong ESA/NASA interest in joint planet-finding mission – Collaborative architecture studies – Discussions on technology planning and development • Joint project leading to launch ~2015 – Scientific and/or technological precursors as required and feasible
