    Project: The Origin and Evolution of Organics and Water in Planetary Systems.

    Description: Did delivery of exogenous organics and water enable the emergence and evolution of life? Why is Earth wet and alive? Along with the origin of Earth’s water, we seek to better understand which organic compounds are generated in interstellar and proto-planetary environments and later delivered to planets. The quest and its interim results inform other questions: Was Mars wet and alive? Do ocean worlds in the outer solar system harbor life? Do habitable worlds exist elsewhere? We address these goals through observational, theoretical, and laboratory research.

    Comets are considered the most pristine bodies of the solar system and their investigation through cosmogonic parameters provides important information on native conditions in the solar nebula. Investigations of cosmogonic thermometers (isotopic ratios, spin temperatures and molecular abundances) encoded by biologically relevant primary volatiles, using next-generation high-resolution echelle spectrometers available now (iSHELL/NASA-IRTF) or within the incoming two years (NIRSPEC2/Keck2, CRIRES+/ESO-VLT) are relevant to understanding the formation and evolution of our planetary system, to testing the delivery of prebiotic matter to the terrestrial planets by small icy bodies and to addressing the puzzling origin of Earth’s oceans.

    Research Project: High Resolution Spectroscopic Studies in Astrobiology

    Description: The importance of studying water and organic molecules is related to their biological relevance. The origin of water oceans and pre-biotic organic molecules on Earth, and the origin of an ancient ocean on Mars, is unsolved. The terrestrial planets formed in a dry region of the proto-planetary disk by aggregation of rocky planetesimals; icy aggregates could form only beyond the frost lines. Even today the bulk Earth is cosmically dry (poor in hydrogen, relative to the protoplanetary disk). About 60 Ma after Earth-accretion, the moon-forming impact probably removed any water that may have outgassed after core formation, leaving the Hadean Earth water-poor at its surface. Yet, early zircons provide evidence that oceans existed by 250 Ma after Earth’s formation. How did terrestrial planets acquire their water? Bombardment of Earth and Mars by icy and rocky planetesimals (represented today by comet nuclei and asteroids) was common from their formation through the Late Heavy Bombardment. Because water is the most abundant native ice in cometary nuclei, with the aggregate CHON ices comprising a close second, we want to understand the role primitive bodies played in delivering water and pre-biotic organics to the young inner planets. Investigations of cosmogonic indicators are necessary to test the hypothesis that small icy bodies delivered water and prebiotic organics to early Earth and Mars. Isotopic ratios (e.g., water D/H, 13/C12C, 15N/14N), nuclear spin temperatures, and chemical abundances in comets are key to identifying temperatures, molecular abundances and physical processes that occurred 4.6 billion years ago in the comet-forming regions of the proto-planetary disk. Observations of Mars will provide new data on the composition, global distribution, and variability of CO2 and trace gases, including isotopologs. Together, the inter-comparison of cosmogonic indicators in comets and in planetary atmospheres through high-resolution spectroscopic studies will address these unresolved questions.
