The full statement is available at: https://tinyurl.com/pv66rj3p 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 AMERICAN ASTRONOMICAL SOCIETY (AAS) DIVISION FOR PLANETARY SCIENCES (DPS) FEDERAL RELATIONS SUBCOMMITTEE (FRS) 2025 ADVOCACY The American Astronomical Society (AAS) Division for Planetary Sciences (DPS) Federal Relations Subcommittee (FRS) (https://dps.aas.org/leadership/frs) conducted our annual advocacy visits in early May 2025. During this year's visits, the FRS met with NASA SMD PSD leadership, House and Senate appropriators, and a series of key House and Senate member offices to discuss ongoing planetary science community concerns and priorities including: the impacts of the Executive Branch FY26 discretionary funding request on the planetary science community, FY26 appropriations requests for both NASA and NSF, and the importance of investing in basic science research in the United States. These FRS advocacy visits follow the early March 2025 DPS Committee advocacy visits. The FRS will continue to serve as a resource for the DPS community by leading advocacy efforts throughout the calendar year (e.g., DPS Action Alerts). Additional advocacy resources can be found on the DPS public policy page here: https://dps.aas.org/public_policy The FRS also accepts new members at any time, and if you are interested in learning more about planetary science advocacy or would like to join the FRS please contact DPS.FRSChair@aas.org.

The 7th BEPIS will focus on new advances, including observation, data analysis, numerical simulation, and instrument development in paleomagnetism, rock magnetism, environmental magnetism, biogeomagnetism, planetary magnetism, geomagnetic modeling, and dynamo theories. Remaining true to original aspiration, the BEPIS is aiming to promote understanding of the origin, structure, and variation of magnetic field of the Earth as well as extraterrestrial bodies. Information about the conference can be found at: https://bepis2025.casconf.cn [Edited for length] 4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4 PHD POSITION IN THE CONTEXT OF THE PRELIFE CONSORTIUM Within the context of the interdisciplinary PRELIFE Consortium, the Forming Worlds Lab at the Kapteyn Astronomical Institute in Groningen invites applications for a PhD position focused on investigating the possible surface water levels and atmospheric composition of the earliest Earth, in an interdisciplinary collaboration between the groups of Tim Lichtenberg (Groningen, tim.lichtenberg@rug.nl) and Wim van Westrenen (Amsterdam). The application deadline will be 10 June 2025. The prospective student will numerically simulate the coupled evolution of the atmosphere and interior of the Hadean Earth during magma ocean crystallisation and perform high-pressure experiments on the solubility of key atmospheric species. The goal is to constrain the oxidation state of the earliest terrestrial atmosphere and to quantify the amount of water released to the surface, to assess the formation potential of key prebiotic molecules within the context of surficial origin of life scenarios. Further information about the position and application procedure can be found at: https://www.formingworlds.space/phdposition2025-hadeansurface The PRELIFE consortium offers in total 15 PhD positions on a range of topics related to the origin of life on Earth and other worlds: https://www.originscenter.nl/prelife/ 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 VIRTUAL COURSE ON WARM DENSE MATTER The High Energy Density Science Center at Lawrence Livermore National Laboratory, in collaboration with the University of South Florida and the University of California, San Diego, is offering a unique interdisciplinary course titled "Warm Dense Matter: Concepts and Fundamentals" in Fall 2025. This course is intended for: (i) advanced undergraduate and beginning graduate students; (ii) Professionals and public interested in high energy density science. More information, can be found at: https://heds-center.llnl.gov/education Registration is required. Please register by emailing your name and institution to Jessica Karlton (karlton1@llnl.gov). Students from US institutions who wish to receive academic credit: - Credit-seeking students on the semester system should also contact Ivan Oleynik (oleynik@usf.edu) - Credit-seeking students on the quarter system should contact Farhat Beg (fbeg@ucsd.edu).

Guest editors are Dr. Kelly Miller (SwRI), Dr. Nora Hanni (Univ. of Bern), Dr. Fabian Klenner (Univ. of Washington), Prof. Brett McGuire (MIT) and Prof. Joshua Krissansen-Totton (Univ. of Washington). This cross-disciplinary issue will cover topics related to carbon in the solar system and beyond, including exoplanet and astrochemical environments. Submissions related to space missions, modeling and laboratory work are welcomed. The submission deadline is 30 November 2025. Manuscripts will be published online when they are accepted, and we expect the print issue to be published in the first half of 2026. Submitted manuscripts must be unpublished and should not be under consideration elsewhere.

We invite you to submit to our session on planetary geomorphology. https://www.confer.co.nz/icg2026/call-for-abstracts/ Planetary missions over the past decade have shown that while surface conditions on planetary bodies across the Solar System vary widely, their landscapes often mirror features found on Earth. Understanding how geophysical flows-such as wind, water, ice, and sediment transport-shape these landscapes is key to interpreting both current and past climatic conditions. This session welcomes abstracts on any aspect of planetary geomorphology, including but not restricted to: Earth analogues, laboratory experiments, numerical models, planetary comparison, mapping, in situ data or remote sensing studies. Studies are welcome that concern rocky or icy solid bodies of the Solar System as well as exoplanets. By bringing together researchers from both planetary science and Earth surface processes, this session aims to foster collaboration and deeper insights into how diverse environments, both on Earth and beyond, respond to physical forces. We hope to see you in New Zealand!
