My detailed assessment and commentary in opposition to OMB proposed modifications to regulations for federal grants has been submitted to the OMB. The complete document is hosted for public viewing by the Planetary Science Cooperative at: https://tinyurl.com/5n8wrbaj The Planetary Science Cooperative website is at: https://coop.planetary-research.org In my opinion, the damage to American science and the consequent damage to the American economy and position in the world that would arise from the implementation of these recommendations are not accidental. This was not written by ignorant buffoons who have no grasp of what is necessary to maintain what has been a vibrant accomplishment of the United States, making it the top destination for science in the world and driving our economy forward for more than 80 years. The damage is the thoughtful and thorough intent of its authors. Mark V. Sykes Senior Scientist and former CEO Planetary Science Institute 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 2026] SESSION P013: ICE AND OCEAN WORLDS - GEOLOGY, OCEANOGRAPHY, CHEMISTRY, AND HABITABILITY If you're heading to AGU this year, we'd like to invite you to submit your abstract and join invited speakers Sam Courville (PSI) and Ryleigh Davis (Caltech) for this session covering the science and exploration of icy and ocean worlds in our Solar System (Earth included!) and beyond to understand processes that may be occurring within such worlds from a multi-/inter-disciplinary perspective. This session highlights several overarching (but not exhaustive) questions: What geological, geochemical and/or oceanographic processes contribute to their evolution? How does interior composition, geophysical structure, and thermal state affect past and present habitability? What do surfaces of ocean worlds tell us about the interior? How might current studies relate to, or be tested by, past/ongoing/upcoming missions? We seek to bridge Earth and planetary sciences through studies spanning from Mercury to Pluto, and all in between. We encourage cross-disciplinary contributions on topics relating to the icy/ocean world theme, including geophysics, geodynamic and seismic modeling, hydrogeology, geochemistry, microbiology, in-situ/remote sensing observations, planetary astronomy, theoretical/modeling/laboratory work, analog investigations, and more. All are welcome!

Methods of understanding these magnetic histories come from investigations into the magnetosphere, crustal magnetism, core dynamics, protoplanetary disk magnetism, and other planetary-body internal magnetic sources. These investigations are typically conducted by using spacecraft or lander measurements, laboratory studies of meteorites and returned samples, and modeling efforts. In this session, we welcome contributions that cover observational, experimental, and theoretical investigations (including method development) of magnetism in Solar System bodies beyond Earth and other astrophysical settings of all scales and originating from remanence, induction, dynamo activity, and plasma interactions with surface and/or interior processes. 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 [AGU 2026] SESSION P028: THE EMERGENCE OF LIFE AS A PLANETARY PROCESS The origin of life is a planetary phenomenon whose elucidation demands integration of approaches spanning planetary science, geoscience, chemistry, and data science. This session explores processes that create, sustain, and modify environments from which life may emerge. We welcome contributions investigating geochemical and geophysical conditions on early Earth, Mars, and other planetary bodies, including redox processes across the atmosphere, hydrosphere, and lithosphere; impact cratering; hydrothermal activity; mineral-fluid interactions and surface catalysis relevant to prebiotic chemistry; and environmental processes that generate notable hallmarks of life such as homochirality and biopolymers. We further encourage submissions applying machine learning and computational techniques to the origins of life, as well as detection and characterization of biosignatures in remote sensing, in situ, and laboratory datasets. This session brings together theoretical, experimental, and observational work advancing our understanding of habitability and the planetary context for life's emergence across the Solar System and beyond.

Maximizing scientific return through interdisciplinary collaboration is more essential than ever. This exploration follows four key themes: 1) physical, chemical, and thermodynamic properties of Mars' interior, 2) the distribution and stability of liquid water and ice inventories using novel and Earth-based methods, 3) the provenance, cycling, and isotopic composition of bio-relevant trace gases, and 4) identification of habitable "refugia environments" where conditions could feasibly support an extant biosphere. For the ninth "New Mars Underground", we invite abstracts that advance these themes, particularly those that integrate remote sensing, modeling, terrestrial analogs/synthetic samples, and mission concept development to illuminate the scientific value that the martian subsurface represents for planetary evolution, comparative planetology, and development of habitable environments. 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 [GSA 2026] GEOLOGICAL SOCIETY OF AMERICA CONNECTS ANNUAL MEETING: ABSTRACT SUBMISSION IS OPEN Abstract submission is open for the Geological Society of America Connects Annual Meeting, October 11-14 in Denver! https://connects.geosociety.org/ Planetary related sessions include: - Big Science from Small Worlds - Boxwork and Fracture Halos: Changes in mineralogy and erosion resistance around fracture features on Earth, Mars, and across the Solar System - Friends of Hoth, Rogue Moons: Icy Ocean Worlds - The G.K.

This session welcomes abstracts on any aspect of planetary geomorphology and surface processes, including but not restricted to: Earth analogues, laboratory experiments, numerical models, planetary comparison, mapping, in situ data, or remote sensing studies. The session brings together researchers studying Earth and other planetary bodies to compare how geomorphic processes operate across different environmental conditions. By fostering dialogue between terrestrial and planetary scientists, it promotes cross-system insight into the fundamental mechanisms that shape landscapes throughout the Solar System. We are also excited to have two excellent invited speakers: An Li (University of Washington) and Harrison Martin (Caltech). The abstract portal is open and can be accessed here: https://gsameetings.secure-platform.com/connects26 The deadline for submitting abstracts is August 6, 2025. Thanks, and we hope to see you in Denver!

This system should involve a broker to buy lunar data from multiple commercial spacecraft operators and to sell it to governments, the private sector, and researchers, in addition to providing an intuitive interface for finding and using the data. Academic researchers conducting fundamental scientific studies of the Moon would need guaranteed government or other support to purchase access to these data. Potomac Database Systems is prepared to fill this gap.
