Sykes, Ph.D., J.D., Senior Scientist at the Planetary Science Institute, misrepresents USRA's actions in response to the Administration's directives on DEI-related matters. His article contains numerous inaccuracies and hyperbole that distort the facts surrounding USRA's removal of DEI content.

This is an important discussion to be had. I have moved the editorials by myself, Robert Herrick, and Elsayed Talaat and the petition organized by early career scientists to a Discord server, providing each with a discussion thread. I will reply to USRA's statements and the statements of others there, and everyone is welcome to participate. Go to: https://discord.gg/CnRc4vgm Mark Sykes, Ph.D., J.D.

Enceladus offers fresh opportunities for advancing our understanding of planetary processes and searching for signatures of potential life. The most accessible ocean material beyond Earth erupts from the internal plumbing system of Enceladus, forming a plume that modifies the space environment at Saturn. This is the 20th consecutive year of this session, attesting to the phenomenal enthusiasm of our community. You won't want to miss this one! We welcome the community to submit contributions diving into diverse ranges of phenomena including but not limited to: cryovolcanism, ice fracturing and other tectonic processes, ocean circulation, water-rock reactions, tidal heating, organic chemistry, life detection approaches, Enceladus's formation, history, and internal structure, and cross comparisons with other ocean worlds including Earth and Europa. Observational, theoretical, laboratory, and field analogue investigations are all welcome. To submit an abstract, please visit: https://agu.confex.com/agu/agu25/prelim.cgi/Session/249971 Abstract deadline: Wednesday, 30 July 2025 at 23:59 EDT Conveners: Christopher Glein (SwRI), Cynthia Phillips (JPL), Fabian Klenner (UW Seattle) 5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5 [AGU 2025] SESSION P012: EXPLORING JUPITER'S ICY MOONS WITH THE NASA EUROPA CLIPPER MISSION AND THE ESA JUICE MISSION Session link: https://agu.confex.com/agu/agu25/prelim.cgi/Session/250483 Abstract Deadline: Wednesday, July 30, 2025, 23:59 EDT NASA's Europa Clipper mission and ESA's Juice mission have both successfully launched and will arrive to the Jovian system in 2030 and 2031, respectively. The comprehensive suite of instruments onboard the two spacecraft presents a unique opportunity to perform individual and joint science investigations en route to Jupiter and within the Jovian system. This session welcomes presentations related to leveraging these missions to significantly advance our understanding of Jupiter's icy moons. Topics include, but are not limited to, surface features and properties, internal structures, dynamics of the subsurface oceans, as well as implications for habitability. We also invite contributions from the complex interactions of Europa, Ganymede, and Callisto with their variable space environment and their dynamic evolution within the Jovian system. Finally, abstracts related to Juice-Clipper synergy ideas, instrumentations of Juice and Clipper, observations, and science opportunities during the cruise are also welcome. Conveners: Nuri Park, Carol Paty, Hao Cao, Pietro Matteoni 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 2025] SESSION P017: GEOLOGY AND GEOPHYSICS OF ACTIVE SATELLITES AND SMALL BODIES This is a session of contributed and invited papers on the geology and geophysics of active or recently active satellites and dwarf planets, including small exoplanets. Research is progressing rapidly due to the stream of new spacecraft and Earth-based telescope data, including Keck, the Large Binocular Telescope Interferometer, and the Atacama Large Millimeter Array. The James Webb Space Telescope has been returning data and Juno is orbiting Jupiter and observing the Galilean satellites. Additionally, Europa Clipper and JUICE, exciting missions to the Jovian system, are in flight. Papers are welcomed on processes that affect the interiors of individual satellites, dwarf planets, and small bodies, as well as the surface expressions they produce. Included are the effects and chronology of internal heating (tidal dissipation and radioactivity), structural evolution (e.g., differentiation), tides, and other geophysical and geological processes (e.g., volcanism, tectonics). Please submit your abstract by Wednesday, 30 July 2025 at 23:59 EDT.

These planetesimals and dwarf planets preserve essential clues about the early Solar System, including accretional processes and thermal evolution. Sample return missions are providing ground truth to remote observations, helping decode planetary formation and evolution. At the same time, national and private space programs are entering the arena and private companies are pushing forward with asteroid prospecting missions. Together, these efforts signal a new era in the study of small bodies - one that is increasingly collaborative, diverse in methods, and rich in discovery potential. We invite abstracts including, but not limited to, space mission data, ground-based observations, modeling, sample returns, planetary defense, and private-sector initiatives. We invite abstract submissions by Wednesday, July 30, at this link: https://agu.confex.com/agu/agu25/prelim.cgi/Session/247514 Conveners: Bryan Holler, Julie Castillo-Rogez, Franck Marchis 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 2025] SESSION P043: THE SYNERGY AMONG THEORETICAL METHODS, LABORATORY STUDIES AND ATMOSPHERIC MODELING - CHEMISTRY, PHOTOCHEMISTRY AND CLOUD PROCESSES IN PLANETARY ATMOSPHERES The study of planetary atmospheres is more vibrant than ever. With the James Webb Space Telescope (JWST) measuring the chemical composition of exoplanetary atmospheres, and with several current and upcoming missions to Solar System bodies like Venus, Jupiter and Titan, the importance and timeliness of this field is clear. A crucial aspect of studying planetary atmospheres is modeling their atmospheric chemistry and aerosol/cloud formation processes. This includes both comprehensive atmospheric modeling and investigations into fundamental chemical processes to better constrain these models. We invite abstract submissions that involve modeling the atmospheric chemistry of planetary bodies beyond Earth. This can include, but is not limited to, atmospheric chemical and photochemical modeling, laboratory studies on chemistry and photochemistry processes relevant to planetary atmospheres, and computational simulations of chemistry and photochemistry pertinent to these environments. The session is open to research aimed at advancing our understanding of planetary atmospheric chemistry beyond Earth.

The main aim is preparation for, and analysis of, the first data back from the ESA/JAXA BepiColombo mission to Mercury, which we are well-positioned for here at Leicester given our leadership of the Mercury Imaging X-ray Spectrometer (MIXS). MIXS will revolutionise our understand of Mercury's surface geochemistry as a nadir pointing instrument capable of global mapping at X-ray wavelengths. This grant spans five years and has four post-doc positions associated with it. Two will be hosted at the University of Leicester, one at Imperial College, and one at the Open University. This represents the first of these exciting positions to be advertised, and the role is focused on planetary geochemistry. Further posts will be advertised next year. The successful candidate will join the BepiColombo MIXS team at Space Park Leicester and will to analyse the first data back from Mercury's surface.
