15 Thermo-Chemical History of Comets and Water Delivery to Earth Studies of Isotopes Across the Solar System (SS) How does presolar deuterium chemistry inform our understanding of D/H in the solar system and the development of Earth s oceans? Measure HDO in 100s of comets for an un-biased survey. Measure accurate isotopic ratios (H, C, N, O) and abundances of trace gases, to constrain models and inform understanding of solar system 2 D/H measurements in comets, from Altwegg, K. et al A larger With a 20m aperture (2e-21 W/m ) we can observe nearly ALL origin and evolution. statistical sample targetscomets are needed to determine the origin Earth sof short and long of period at multiple epochs. NOTE:ofFigure ocean and measure the dispersion of this ratio in both dynamic families. Merit (FOM) = [ log10 (Delta) mV The Origins Space Telescope: Q(H2O)/ (AU)*1028]/Delta. Stefanie Milam
