While the long-term evolution of the Earth is constrained by geological studies and isotopic analyses, the evolutionary paths of other planets must be reconstructed from data obtained through astronomical observations and planetary missions. Models of planetary atmospheres use these observations to highlight governing physical processes operating from the Earth to other planets in our Solar System and beyond. The rapidly increasing number of discovered exoplanets provides a new opportunity for interdisciplinary collaborations between heliophysicists, astrophysicists, geoscientists, biochemists, planetary and climate scientists concerning the physical and chemical evolution of (exo)planetary atmospheres and planetary habitability. This session welcomes observational, theoretical, experimental, and field studies relevant to the atmospheres, evolution, and habitability of planets in and outside of our Solar System. https://agu.confex.com/agu/fm19/prelim.cgi/Session/79425 The deadline for abstract submission is Wednesday, 31 July 2019. Convenors: Feng Tian (Macau University of Science and Technology), Cedric Gillmann (Free University of Belgium) Vladimir Airapetian (NASA/GSFC/SEEC & American University) 2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2 AGU SESSION P022: MACHINE LEARNING FOR PLANETARY SCIENCE Machine Learning (ML) is the subfield of computer science that gives "computers the ability to learn without being explicitly programmed." As increasingly large, complex datasets are acquired, autonomy and machine intelligence will have a critical role in the interpretation of data from planetary exploration missions. There is a need for frameworks that can rapidly and intelligently extract information from these datasets in a manner useful for scientific analysis. This session will explore research that leverages machine learning methods to enhance our scientific understanding of planetary data and to increase the scientific return from exploration missions. This session will also explore ways of introducing machine learning into existing analysis workflows. Topics may encompass data analysis on the ground (post-downlink) as well as onboard a spacecraft for existing or future planetary exploration missions and instruments. https://agu.confex.com/agu/fm19/prelim.cgi/Session/78481 3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3 AGU SESSION P017: ICE FROM GRAINS TO LANDSCAPES: SURFACE PROCESSES ON ACTIVE ICY WORLDS We would like to invite submissions to our Icy Worlds AGU session this fall in San Francisco. As we consider the in situ exploration of outer Solar System worlds - such as icy satellites, small bodies, and Kuiper Belt objects - increasing collaboration between those who study surface processes on landscape scales and those who study processes at the scale of a landed robotic vehicle will continue to increase in importance. To gather these different scientific communities together, we invite contributions ranging in focus from comparative planetology and remote sensing, to laboratory analogs, instrumentation and experiments, to theoretical and numerical modeling. We intend for this session to foster more collaboration between these communities, so that we may continue to explore the commonality of surface processes on icy worlds, despite their dispersion across the Solar System.

On Earth, low frequency sound ("infrasound") sensors can capture signals from natural sources (volcanoes, earthquakes, severe storms, bolides, etc.) and human activities (chemical and nuclear explosions, supersonic aircraft, wind turbines, dams, etc.). These sounds can be inverted to determine atmospheric structure. They may also carry energy into the upper atmosphere, creating localized heating. The recent detection of Martian infrasound via the InSight lander has highlighted the scientific dividends of acoustic monitoring on other Solar System bodies as well. In fact, studies of acoustic wave propagation have been performed for Venus, Jupiter, and Titan; there is an increasing recognition that sound waves can provide details on a variety of phenomena that cannot be captured from orbit. This session is dedicated to highlighting studies of acoustic waves on the Earth and beyond. We invite theoretical, numerical, and experimental studies in geophysical and planetary acoustics.

Submissions are encouraged from either telescopic or spacecraft spectroscopy that highlight new results. Additionally, in celebration of AGU's centennial, we also encourage submissions on the history and evolution of our understanding of surface compositions as spectroscopic techniques have improved or as we have achieved increased spatial resolution with spacecraft flybys, orbiters and landers. Submissions on spectroscopy from laboratory studies, extraterrestrial materials, and Earth analogs are also welcome. https://agu.confex.com/agu/fm19/prelim.cgi/Session/76881 Conveners: Wendy Calvin (UNR), Diana Blaney (JPL), Vicky Hamilton (SWRI), Bethan Ehlmann (Caltech) 6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6 AGU SESSION EP036: SHAPING LANDSCAPES OF THE SOLAR SYSTEM - ENVIRONMENTAL FLOWS ON OTHER PLANETS Quantitative models for surface processes have been derived for Earth systems. When applied to other planetary bodies, these Earth-based models can provide critical insights into the geologic history of the Solar System. In return, planetary surfaces across the Solar System offer a unique opportunity to test these models under conditions often unachievable on Earth. We invite a range of contributions in the field of planetary surface processes with an emphasis on fluid and granular flows (fluvial, eolian, glacial, mass wasting, coastal, etc.) and that use laboratory experiments, theoretical and numerical modeling, and planetary-exploration data from orbiters, landers, and rovers. This session's goal is to explore the interplay between quantitative models for planetary surface processes and new planetary exploration data that often challenge these models. We intend this session to foster more collaboration between members of the PS and EPSP sections.

Impact events on the early Earth undoubtedly had profound effects on early life, if not the origin of life. The effects of shock metamorphism combined with the generation of post-impact hydrothermal systems in the presence of adequate water make impact environments attractive astrobiology targets. This session will discuss the beneficial biological consequences and astrobiological implications of meteorite impact events and impact craters: including habitat modification, generation of subsurface habitability, biosignature preservation, microbial metabolic implications and planetary exploration targets. https://agu.confex.com/agu/fm19/prelim.cgi/Session/82641 8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8 AGU SESSION P029: PLANETARY ATMOSPHERIC, SURFACE, AND INTERIOR SCIENCE USING RADIO AND LASER LINKS Solar System exploration has been advanced over the past five decades via Radio Science techniques to study planetary and solar phenomena as well as fundamental physics. The scope of this session includes investigations within the Solar System as well as tests of fundamental physics to expand the frontiers of Solar System exploration using radio and optical science to address the study of ocean worlds, planetary and small body interiors, the dynamics, composition, and thermal structure of planetary atmospheres, characterizing the scattering, electrical, and other properties of planetary surfaces, and research in fundamental physics and Solar System dynamics. Relevant technology topics include the design of small spacecraft networks and constellations, advances in flight and ground instrumentation, advances in space clock technologies, novel communications architectures including optical links, advances in radio and laser technologies, and new techniques and instrumentation for entry probe radio science. The submission deadline is Wednesday, 31 July 2019. https://agu.confex.com/agu/fm19/prelim.cgi/Session/74030 Conveners: David H. Atkinson, JPL, David.H.Atkinson@jpl.nasa.gov Sami.W.

If you would like to present your work on radiative transfer model development involving scattering particles and applications of such novel models in a remote sensing context please consider submitting an abstract to this session before the deadline on July 31, 2019. https://agu.confex.com/agu/fm19/prelim.cgi/Session/71478 10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10 AGU SESSION P007: COMPARATIVE PLANETOLOGY: LARGE PLANETESIMALS AND DWARF PLANETS THROUGHOUT THE SOLAR SYSTEM Observations returned by space missions (e.g., Dawn, New Horizons, Cassini) and large Earth-bound telescopic surveys (e.g., NEOWISE, Adaptive optics observations) over the past decade offer a broad encompassing view of the population of large planetesimals and dwarf planets that formed shortly after Solar System formation. Most of these bodies have retained information on their accretional environments while others have undergone significant internal evolution. The Psyche and Lucy missions now prepare to continue deciphering the Solar System's early history with the exploration of 16 Psyche and Jupiter's Trojan asteroids, while instruments on the extremely large telescopes available in the next decade will provide observations with unprecedented details of many large planetesimals. This session welcomes abstracts that address new observations and models of large planetesimals found across the Solar System, compare and contrast the properties of planetesimals found in various small body reservoirs, and address their possible genetic relationships.
