In the research project data from EISCAT3D will be used. EISCAT3D collects atmospheric and ionospheric data using Incoherent Scatter Radar (ISR) techniques and provides information about the complex systems in the atmosphere and the interaction between the Sun and the Earth, e.g., northern lights, space weather, meteors incidents and climate issues. In this project, this information will be made accessible through interactive visualization, giving possibilities for both researchers and a general public to explore the phenomena and processes that characterize the atmosphere. The full advertisement can be found at: https://bit.ly/3ipM4xH The closing date is August 15, 2021.

POSITION IN MACHINE LEARNING FOR PLANETARY IN-SITU SPECTROSCOPIC DATA AT GERMAN AEROSPACE CENTER IN BERLIN A newly founded junior research group at the German Aerospace Center (DLR) in Berlin will investigate methods from the field of machine learning for the analysis of spectroscopic in-situ planetary data. Techniques like laser-induced breakdown spectroscopy (LIBS) or Raman spectroscopy have many advantages for the robotic exploration of extraterrestrial bodies and Mars missions such as the recently landed rover Perseverance and its predecessor Curiosity are equipped with such instruments. However, the physics behind these methods is complex and not all problems can be solved analytically. Therefore, we want to investigate machine learning methods to address the challenging complexity in the data. The Ph.D. project will include laboratory measurements with highly performant but also compact instrumentation, simulating, for example, Martian atmospheric conditions. The focus will be on the classification and identification of geological samples, thus different types of minerals and rocks. We are looking for a motivated and enthusiastic student with an expertise in data science and a high interest in the Solar System exploration.

Category IIa concerns all missions to the surface of the Moon whose nominal mission profile does not access the areas defined in Category IIb below. For those missions, the material inventory recommended by COSPAR will now be limited to those organic products that may be released into the lunar environment by the propulsion system. Category IIb concerns all missions to the surface of the Moon whose nominal mission profile accesses the socalled Permanently Shadowed Regions (PSRs) and the lunar poles, in particular latitudes south of 79S and north of 86N. For these missions, a full organic inventory, i.e. for solid and volatiles, will still be recommended.

The combination of such constraints help to improve our understanding of the physical and chemical processes that have shaped the interior of rocky bodies in the Solar System through time. The increase of computational power and improvements in experimental techniques have made it possible to tackle complex scenarios relevant for pressure and temperature conditions that govern the interior of planets and moons, in order to understand their current and past dynamics. This session invites contributions from numerical modeling and experimental work that incorporate current planetary mission data and address future measurements that are necessary to place constraints on the evolution and present day state of planetary interiors for the Moon, Mars, Mercury, Venus and beyond. Invited Speakers: Sue Smrekar (JPL) and Simon Stahler (ETH) Conveners: Angela G Marusiak, Melanie Drilleau, Anna Mittelholz, Ana-Catalina Please, and mentee: Gunda Goutham Krishna Teja Submit your abstract via: https://agu.confex.com/agu/fm21/prelim.cgi/Session/121569 16-16-16-16-16-16-16-16-16-16-16-16-16-16-16-16-16-16-16-16-16-16-16-16 AGU SESSION EP008: EARTH AND PLANETARY SURFACE PROCESSES GENERAL CONTRIBUTIONS We welcome contributions to this general poster session related to the disciplines, processes, and techniques involving the study of the surface of Earth or other planetary bodies. This session provides the opportunity for contributions that fall within the broad spectrum of Earth and Planetary Surface Processes. Contributions are welcome from a wide spectrum of disciplines including, but not limited to, geomorphology, sedimentology, planetary science, geophysics, engineering, atmospheric science, geology and biology. Processes of interest include, but are not limited to, fluvial, hillslope, tectonic, volcanic, glacial, coastal, marine, eolian, biologic, cryospheric and impact processes. We also welcome contributions to techniques in Earth and Planetary Surface Processes, such as field observations, numerical and physical modeling, remote sensing, geodesy, nonlinear dynamics, geochronology, geochemistry and geophysics. Take care, Claire Masteller, Brooke Hunter, Mackenzie Day, and Rose Palermo 17-17-17-17-17-17-17-17-17-17-17-17-17-17-17-17-17-17-17-17-17-17-17-17 AGU SESSION EP036: SURFACE PROCESSES ON EXTRATERRESTRIAL ROCKY BODIES Quantitative models derived for surficial processes on Earth are often applied to other planetary bodies, providing critical insights into the geologic history of the Solar System. Extraterrestrial surfaces present opportunities to test these models under conditions that are often unachievable on Earth or in the laboratory. This session's goal is to explore the interplays between quantitative models of planetary surface processes and the challenges imposed on these models by new planetary data. We invite contributions in the field of planetary surface processes that use planetary analogues, laboratory experiments, theoretical and numerical modeling, and planetary exploration data from robotic spacecraft. We intend for this session to foster more collaboration between members of the PS and EPSP sections. Invited speakers: Rachel Glade (University of Rochester) Anna Grau Galofre (Arizona State University) Conveners: Alexander Morgan (PSI) Marisa Palucis (Dartmouth) Samuel Birch (MIT) Orkan Umurhan (SETI/NASA Ames) Abstracts can be submitted through the AGU portal through the deadline of August 4 at 23:59 EDT: https://agu.confex.com/agu/fm21/prelim.cgi/Session/122582 Also consider submitting to the sister session, P033 - Surface Processes on Active Icy Worlds 18-18-18-18-18-18-18-18-18-18-18-18-18-18-18-18-18-18-18-18-18-18-18-18 AGU SESSION P014: HYDROTHERMAL PROCESSES IN THE EVOLUTION OF SOLAR SYSTEM BODIES Hydrothermal settings host heated fluids reacting physically and chemically with surrounding rocks. On Earth, those occur deep in the critical zone marked by coupled biological, chemical, geological, thermophysical and atmospheric processes. Decoupled from photosynthesis, microbes can use leachate-rich water via organic-rich sediments, redox gradients, and thermal energy for metabolism, making habitable zones plausible throughout the Solar System. Thermal sources tied to planetary evolution, such as magma bodies, meteoritic impacts, radiogenic heating, tide-flexing and metamorphism underpin hydrothermalism. Hydrothermal cooling can also modulate geophysical evolution, by curtailing the viscoelastic relaxation of subsurface topography. However, the extent of thermal sources, signatures of paleo-hydrothermalism, and associated timescales are poorly known. Accordingly, we welcome works on the role of hydrothermal processes in geologic and biologic evolution across the Solar System, including ocean worlds like Europa. Laboratory and field findings, such as of amagmatic hydrothermal sites, and connections between Earth and planetary systems are especially welcome. Conveners: Suniti Karunatillake, Saman Karimi, Sonia Tikoo, Scott M Perl, Jonathan E Snow To submit your abstract go to: https://agu.confex.com/agu/fm21/prelim.cgi/Session/123966 19-19-19-19-19-19-19-19-19-19-19-19-19-19-19-19-19-19-19-19-19-19-19-19 AGU SESSION P016: ILLUMINATING THE MARTIAN ROCK CYCLE WITH REGIONAL GEOCHEMISTRY Summary: Chemical maps of Mars, derived from the Mars Odyssey 2001 mission's gamma and neutron spectrometers, regionally characterize the distribution of key elements at depth scales unmatched by other missions. Resulting works address unknowns of the martian rock cycle, such as changes across Noachian-Amazonian eons in pathways from igneous rocks to sediment to lithification. Those span soil alteration processes across Mars, thermal evolution of the mantle, provenance of globally distributed dust, etc. However, unresolved questions remain, such as the provenance of chemical provinces, evolution of individual volcanic provinces, and processes enriching K and Th in the lowlands. Accordingly, we solicit presentations on the synthesis of in situ and regional observations; on geological interpretations from regional geochemistry; and on refining the chemical maps. Regional geochemical context for in situ regolith evolution as at Jezero Crater, geochemical constraints on geophysical properties, and analog studies to interpret geochemical signatures are similarly welcome. Conveners: Suniti Karunatillake, James Wray, Rohana Chandrajith, Vashan Wright and Jennifer Whitten Abstract submissions: https://agu.confex.com/agu/fm21/prelim.cgi/Session/124439 20-20-20-20-20-20-20-20-20-20-20-20-20-20-20-20-20-20-20-20-20-20-20-20 AGU SESSION P017: IN SITU GEOPHYSICAL EXPLORATION OF PLANETARY BODIES Recent planetary landers and rovers have introduced new geophysical approaches to characterizing planetary bodies. The acquisition of geophysical data (e.g. magnetic, radar, seismic, thermal, permitivity, etc.) makes it possible to characterize in unprecedented detail the interior of the study target, helping detect cores, characterizing regoliths, and exploring near-surface resources that could one day sustain long-lived exploration. We invite abstracts that present results from recent missions that involve geophysical instruments, such as InSight, Hayabyusa2/MASCOT, and the Chang'E 3, 4, and 5 landers and rovers. Discussion of novel exploration strategies, methods, and instruments that could be deployed in upcoming missions to the Moon, Mars, Europa, and elsewhere, are also welcome. https://agu.confex.com/agu/fm21/prelim.cgi/Session/120500 The deadline for all submissions is Wednesday, August 4, 2021 at 23:59 EDT. Regards from the conveners, Laurent Montesi, Matthias Grott, Renee C Weber, Zhiyong Xiao 21-21-21-21-21-21-21-21-21-21-21-21-21-21-21-21-21-21-21-21-21-21-21-21 AGU SESSION P021: MARS SAMPLE RETURN - CHALLENGES AND ADVANCES IN PLANNING FOR THE FIRST SAMPLES FROM ANOTHER PLANET Mars Sample Return (MSR) has long been a high priority for the international planetary science community. The Perseverance rover is currently at work exploring the Jezero Crater region of Mars with the goal of assembling a set of scientifically compelling samples from geologically diverse areas. Beginning in 2018, NASA and ESA have been working jointly on planning to achieve Mars Sample Return with the current goal of delivering the samples to Earth as early as 2031. This session will include posters that address topics such as the science that could be achieved with the samples collected by Perseverance importance of MSR, how the science benefits will be shared across the science community, engineering and planetary protection planning status updates, recommendations for the Sample Receiving Facility (SRF), planning for sample analyses, and public engagement and outreach strategies. Participation is possibly either virtually or in-person. The conveners invite abstracts to be submitted through August 4: https://agu.confex.com/agu/fm21/prelim.cgi/Session/122322 We look forward to an exciting session.

The deadline is August 4 2021 at 23:59 EDT. NASA's MESSENGER mission revolutionized our understanding of Mercury's surface, interior, exosphere, magnetosphere, and heliospheric environment. That understanding will soon take a major step forward with data from the first flyby of Mercury by the ESA-JAXA BepiColombo mission, subsequent flybys, and eventual orbit. In this session, we welcome all contributions on data analysis, laboratory measurements, ground-based observations, analog studies and theoretical developments that build on the current state of knowledge of Mercury, as well as papers that focus on how BepiColombo measurements collected during the recent Earth and Venus flybys can be used to support investigations at Mercury. The topics of interest for this session include Mercury's geology, geochemistry, and geophysics, and plasma dynamics occurring in Mercury's exosphere and magnetosphere. We also strongly encourage papers discussing how outstanding questions about Mercury can be addressed by future observations expected from BepiColombo. https://agu.confex.com/agu/fm21/prelim.cgi/Session/125447 23-23-23-23-23-23-23-23-23-23-23-23-23-23-23-23-23-23-23-23-23-23-23-23 AGU SESSION P032: SPACE ENVIRONMENTS AND WEATHER OF UNMAGNETIZED OR WEAKLY MAGNETIZED SOLAR SYSTEM BODIES Hybrid Meeting, New Orleans, December 13-17 2021 The ionospheres and magnetospheres of weakly magnetized bodies with substantial atmospheres (e.g. Mars, Venus, Titan, Pluto and comets) are subject to disturbances due to solar activities, interplanetary conditions, or parent magnetospheric environments (e.g. solar flares, coronal mass ejections and solar energetic particles), sharing similarities with their magnetized counterparts but with scientifically important differences. This session invites abstracts concerning remote and in-situ data analysis, modeling studies, comparative studies, instrumentation and mission concepts for weakly magnetized Solar System bodies. Topics such as dayside and nightside ionospheric characteristics and variability, ion-neutral coupling, and responses of the ionized and neutral regimes to transient space weather events are especially encouraged. https://agu.confex.com/agu/fm21/prelim.cgi/Session/117812 Deadline: August 4, 2021 Conveners: Christopher Fowler, Beatriz Sanchez-Cano, Xiaohua Fang, Yingjuan Ma 24-24-24-24-24-24-24-24-24-24-24-24-24-24-24-24-24-24-24-24-24-24-24-24 AGU SESSION P033: SURFACE PROCESSES ON ACTIVE ICY WORLDS The extreme conditions and exotic ices on the surfaces of outer solar system bodies result in unique landscapes not commonly observed on rocky bodies. Sublimation of volatile ices controls the evolution of many icy world landscapes and has given rise to planetary climates, while tectonic and eruptive processes evolve ice shells, interacting with potentially habitable subsurface oceans. The many interrelations between these processes are only beginning to reveal themselves; as exploration of the outer Solar System proceeds at a progressively rapid rate, the complexities of these worlds will continue to grow. To piece together these exotic planetary landscapes, will require investigations that incorporate increasingly diverse scientific techniques and collaboration between the many sub-communities studying icy worlds - from those who study comets, to Arrokoth, and everything in between. We invite contributions ranging in focus from comparative planetology and remote sensing, to laboratory and analog studies, to theoretical and numerical modeling.

It is also an Ocean World, with a deep interior water ocean that may provide a harbor for life. Photochemistry in the stratosphere consumes methane and generates a wealth of complex organic molecules, similar to the atmospheric chemistry of prebiotic Earth. Molecules grow in size through a variety of processes, ultimately forming haze particles that settle on the surface and are reworked into large equatorial dune fields. In the lower atmosphere methane and ethane form lakes, seas, clouds and rain in a weather cycle analogous to the Earth's water-based meteorology. The surface exhibits infrequent craters, but offers other mysterious landforms interpreted as mountains, putative cryovolcanoes, tectonic features, and fluvial/lacustrine morphologies. In this session we welcome all recent research relevant to Titan, including new observations, spacecraft data analysis, modeling and laboratory experiment work.
