Understanding this boundary is pivotal for interpreting Earth's magnetic field observations, seismic behavior, and gravitational characteristics. This session aims to bring together the latest geophysical studies to characterise and understand the CMB's structure, including its topography and the existence of stable layers, its dynamics, and how these elements influence the evolution of our planet's interior over various timescales. We encourage submissions that offer new insights into these complex dynamics, including simulations and seismic, magnetic, mineralogical, and gravimetric data analyses.

How can laboratory, modeling, and analog studies complement lander, rover, and orbiter data? Can we infer past climate and habitability on other planets from studying aqueous processes? If you're interested in these questions and any others related to aqueous processes across our Solar System, please submit an abstract to our session by July 31, 2024! This session intends to increase collaboration across the Earth and planetary communities and to encourage the exchange of expertise between scientists who use different techniques!

Magnetic data are typically available from satellites, meteorites, or from surface measurements. In this session we welcome contributions that cover observational, experimental, and theoretical investigations (including method development) of the magnetosphere, crustal magnetism, core dynamics, protoplanetary disk magnetism and other planetary-body internal magnetic sources.

The Planetary Decadal survey highlights the vast array of scientific questions to be answered through exploration of our diverse Solar System. In current challenging budgetary times, with many destinations and science questions to choose from, development of lightweight, low-cost, cutting-edge enabling technologies remains more important than ever. The advent of affordable, accessible Artificial Intelligence (AI) in the past several years presents an exciting enabling technology for planetary missions, but also raises questions about safety and reliability. AGU session P007 is now open for abstract submission and solicits concepts for novel planetary missions and instruments across the entire spectrum of technologies that can play a role in future exploration of the Solar System.

The data collected during these flybys provided unprecedented views of these Jovian moons. Juno's multi-instrument measurements include high-resolution imagery in visible, ultraviolet, and infrared of the surface geology and composition, microwave subsurface sounding, electromagnetic sounding of the sub-surface conductive layers, gravitational sounding of the interior, as well as the characterization of the electromagnetic fields and particles environment of these moons. This session welcomes papers on the observations and models related to Juno's flybys of Europa, Ganymede and Io, focusing on the surface composition and geology, ice-shell thermal structure, ocean dynamics, the structure and dynamics of deeper layers as well as atmospheric and space environment studies. Ground and space telescope observations of the Jovian moons and modeling work in anticipation of the Europa Clipper and Jupiter Icy Moons Explorer (JUICE) missions are equally welcome.

Importantly, HWO will also have a science scope that can address elements of the Planetary Science and Astrobiology Decadal Survey through its imaging and spectroscopy of Solar System worlds. This Great Observatory will revolutionize our understanding of habitability, search for signs of life elsewhere, and study planetary system formation/evolution in our Solar System and beyond. This session invites presentations focused on the major science questions that could be answered with HWO. Key topical areas will include characterizing exoplanetary atmospheres, potential biospheres, and surface environments through direct imaging and transits; Solar System science; understanding planetary systems; and exoplanet demographics.

Topics may address Mercury's interior, surface, chemical composition, dynamics, exosphere, thermal and magnetic evolution, as well as investigations of Mercury-like exoplanets. Relevant research approaches include, but are not limited to, spacecraft data analysis, ground-based observations, laboratory experiments, and numerical simulations. Contributions highlighting results (or expected results) from the ESA-JAXA BepiColombo mission are particularly welcome, as are studies emphasizing a multidisciplinary approach or highlighting new concepts for future investigations. The deadline to submit abstracts is Wednesday July 31, 23:59 EDT. Go to: https://agu.confex.com/agu/agu24/prelim.cgi/Session/226868 Our invited presenters are Dr. Asmaa Boujibar (Western Washington University) and Dr. Sebastien Besse (European Space Agency).

It also hosts familiar features seen elsewhere in the Solar System: craters, dunes, mountains, ridges and gulleys. The Cassini-Huygens mission of 2004-2017 thrust Titan into the limelight as never before, and it is poised to take center stage again the 2030s with the arrival of Dragonfly. Meanwhile, a flurry of laboratory, theoretical and astronomical study continues apace, working to unravel deeper mysteries from the Cassini-Huygens dataset and to prepare for Dragonfly's arrival. AGU session P038 is now open for abstract submission, and solicits talks and posters from all aspects of Titan related science, including laboratory, theoretical, observational and related field analog research.

While there continue to be opportunities for UV remote sensing from Earth orbit and in future robotic missions, the infrastructure for UV instrumentation is at a crossroads. Existing orbital facilities are nearing the end of their useful lives and there continue to be many phenomena that cannot be effectively studied with existing, high-heritage instrument designs. Exciting advances in UV-optimized technologies promise new capabilities that can be incorporated into the next generation of robotic probes, flexible SmallSat missions, and large aperture space-based observatories. This session welcomes abstracts covering UV science results, as well as reports on progress toward developing new technologies such as UV detectors, high performance coatings and novel sensor designs. We welcome your abstract submissions for this session!

This coupling plays out in dramatic fashion during geomagnetic storms, when ground and space-based assets are most susceptible to space weather effects. Topics in this session include: (1) Structure and dynamics of the strongly driven magnetosphere during intense space weather events; and (2) Strongly driven magnetic reconnection and its coupling to the larger scale geospace environment. In-situ space-borne observations (such as MMS, THEMIS, and Van Allen Probes, etc), remote/ground-based measurements, and advanced numerical simulations are invited covering all regions of Earth's magnetosphere. This session's goal is to reveal three-dimensional connections of the dynamic storm-time magnetosphere through multi-point observations and numerical simulations. The submission deadline is July 31, 2024, at 11:59 PM EDT. Go to: https://agu.confex.com/agu/agu24/prelim.cgi/Session/225153 Student and early-career contributions are especially encouraged!

Since then, NASA has returned samples from a comet (Stardust mission) and the Sun (Genesis mission), JAXA's Hayabusa and Hayabusa2 missions have returned samples from two asteroids, Itokawa and Ryugu, and NASA's OSIRIS-REx mission recently returned samples of asteroid Bennu. We are arguably in a golden age for sample return missions, with more samples to be returned from the Moon and Mars in the coming years. This session highlights the significance of past and future sample return missions in furthering our understanding of our planet and Solar System, including geological and atmospheric processes on the terrestrial planets, the origin of life, and the even the formation and potential habitability of other worlds beyond our Solar System.

The first, a two-day virtual workshop, "Science and Planetary Protection in Advance of Human Missions Seminar", will take place on July 31 and August 1, 2024. It will introduce key discussion topics and knowledge gaps, led by community experts and based on the latest available data. We will ask attendees to contribute to brainstorming sessions to identify forward work and potential priorities for the subsequent workshop. The second, a three-day virtual workshop to be held in Fall 2024, will collect abstracts from the community to introduce mission concepts, research questions, and considerations based on discussions at the first event.
