To continue that upward trajectory, the PSJ solicits applications to join the team of Scientific Editors (SEs). AAS SEs are expected to comply with the AAS Code of Ethics and commit about 10% full-time equivalent effort to their work for the Journals. Scientific Editors receive a grant of approximately $15,000 per annum for their services, plus travel support for the annual meeting. To apply, submit a CV and 2-3 page cover letter describing your interest in the role and your related experience to the incoming PSJ Editor-in-Charge, Brian Jackson (brian.jackson@aasjournals.org).

Session Link: https://agu.confex.com/agu/abscicon26/prelim.cgi/Session/277054 Astrobiology relies on an extraordinary diversity of data, from field analogs and laboratory experiments to mission observations and modeling efforts. As Artificial Intelligence (AI) and Machine Learning (ML) approaches become central to discovery, linking these diverse datasets is essential for revealing the broader patterns that shape planetary habitability and the potential for life. This session focuses on how data collection, integration, and cross-disciplinary frameworks enable new insights in astrobiology. We welcome submissions on the current astrobiology data ecosystem, new and existing data repositories relevant to the community, ontologies and other organizational schemes, metadata standard development, practices for hosting and sharing data, tools relevant to mining or working with existing astrobiology data, managing multi-modal datasets, and projects that have made notable or creative use of astrobiology open science resources. Conveners: Diana Gentry, Sunanda Sharma, Rachel Slank, Matt B Weller 3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3 [NASA] ROSES-25 AMENDMENT 24: F.10 PRISM DUE DATES RESET AND OTHER CHANGES This Amendment defers three dates for this program element: The pre-proposal webinar will occur December 5, 2025, at 1 pm Eastern Time, see the PPC connect information in Section 9; Step-1 proposals are now due December 12, 2025; and Step-2 proposals are now due February 20, 2026. Moreover, a few other changes were made: In Section 2.1 a paragraph about the direct purchase of goods, supplies and/or services from non-U.S. sources was expanded; small changes were made to Section 3.1 to provide updated guidance on landing site hazard analyses; and a paragraph referring to cooperative agreements as the award type was removed from Section 5. New text is in bold, deleted text is struck through. FAQs will be posted shortly under "Other documents" on the right side of the NSPIRES page for F.10 PRISM.

Instruction: https://tinyurl.com/55h8hsfh (shortened) This session offers a comprehensive forum for research on small bodies throughout and beyond our Solar System, including asteroids, comets, KBOs, irregular satellites, meteoroids, and interstellar objects. We invite presentations covering all methodologies in small-body science, including observations, spacecraft missions, laboratory experiments, and theoretical modeling. Contributions on future mission prospects, deep all-sky surveys, and planetary defense projects are also welcome. Our goal is to highlight the latest and most significant advancements in small-body research worldwide, with a special focus on developments from the Asia-Oceania region, and to foster international collaboration. We look forward to your active abstract submissions. Sincerely, Toshihiro Kasuga, Takafumi Ootsubo, and Man-To Hui 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 PHD AND POSTDOC OPPORTUNITIES AT THE UNIVERSITY OF BERN: EXPLORING ABIOTIC ORGANIC COMPLEXITY The Space Research and Planetary Sciences Division at the University of Bern is offering two PhD positions and one PostDoc position focused on analysing legacy data from ESA's Rosetta mission to comet 67P/Churyumov-Gerasimenko. These positions are dedicated to the data-driven investigation of cometary abiotic organic complexity (AOC) based on highly convolved high-resolution mass spectra, with the goal of developing a reference framework for future space missions, including those searching for signs of extraterrestrial life. Working within an interdisciplinary team that combines astrobiology with analytical chemistry (namely, mass spectrometry) and data science, successful candidates will systematically inventory prebiotic molecular signatures or develop data-analysis pipelines that integrate chemometrics/multivariate statistics and scientific machine learning to enable an unbiased, data-driven characterization of cometary AOC.

We serve the planetary science community by: hosting annual professional meetings; advocating for robust funding for planetary science; supporting students and early career professionals; promoting equitable and inclusive conditions for all; fostering international collaboration; and increasing public awareness and interest in planetary science including the cross-cutting issues that affect Earth and all its inhabitants. Membership yields discounted registration for the Fall 2026 Meeting to be held 25-30 October in Spokane, WA which will have a broad program of science and workforce topics, with a special focus on planetary mission anniversaries. DPS does not censor submissions – diverse perspectives are welcome. Applications are welcome as a lower-cost affiliate member in DPS, or a full member in both AAS and DPS. Anyone with a full membership in both AAS and DPS is entitled to a 15% discount on page charges for one paper in any AAS journal.

These reports are designed for the non-MSL team member to be able to see what observations MAHLI has acquired, and what the rationale was for taking them. These are searchable word docs, so a target name is sufficient to isolate where the MAHLI image was taken and when, as well as the associated technical info (picture number, etc.). MAHLI Tech Rept 0040 - Sols 4355-4488, is released. These are data that were released to the public via NASA PDS. The Tech Report can be found on both Zenodo and Research Gate. The citation is: R. A.

Our speakers Therese Encrenaz (Paris Observatory) and Rakesh Mogul (California State Polytechnic University) recently published brand new results that feed new information into this study. Therese Encrenaz has been observing Venus for decades from Earth and she will provide with an overview of her findings. Rakesh Mogul re-analysed Pioneer Venus descent probe data and discovered new information about the chemical composition of the sulpheric acid cloud particles. Join us in this 75 minutes long get-together listening to these new findings, and participating in the open informal discussion that will follow to share your thoughts on this enigmatic topic. This webinar will be in normal-Zoom-mode, with all attendees being able to have video and audio if they wish. Both speakers will present for 25 minutes. After that we have 25 minutes time for discussion about the topic among all the participants. Please bring your ideas and thoughts on the topic and let's engage in an interactive and constructive scientific discussion!
