It also encompasses a breadth of research methods, including field analogs, laboratory experiments, mission observations, and modeling efforts. The challenges in discovery, generation, and interlinking of these diverse data sources is ever more essential for revealing the broader patterns that shape planetary habitability and the potential for life, especially as artificial intelligence (AI) and machine learning (ML) capabilities continue to expand. This session focuses on cross-disciplinary data collection, integration, and frameworks in astrobiology. We welcome submissions on the current data ecosystem, relevant data repositories, ontologies and other organizational schemes, metadata standard development, practices for hosting and sharing data, data mining or analysis tools, managing multi-modal datasets, and projects that have made notable or creative use of astrobiology open science resources.

A new era of human and robotic lunar exploration is opening up exciting opportunities in scientific understanding as humanity reaches toward the Moon again. Missions such as the Artemis, Chang'e, Chandrayaan, and commercial programs offer incredible avenues to develop a deeper scientific understanding of our nearest celestial neighbor. This session highlights science that enables and is enabled by our return to the Moon. These include lunar science results from recent missions, preparations for upcoming lunar missions, as well as laboratory and computational investigations that will broaden our knowledge about the Moon and facilitate future lunar exploration. We welcome investigations of the Moon and beyond that will be uniquely enabled by being done from the Moon. Areas of particular interest include dust, volatiles, radiation, geological processes and their mutual interactions, as well as future lunar instruments and mission concepts. Abstracts are due Wednesday August 5, 2026 11:59 pm EDT Abstracts may be submitted to AGU here: https://agu.confex.com/agu/agu26/prelim.cgi/Session/279680 Thank you, Phillip Phipps, Li Hsia Yeo, Paul Szabo, and Jan Deca 10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10 [AGU 2026] Session SY029: Open Source Tools for the Earth & Space Sciences - Breaking Discipline Silos to Accelerate Discovery Abstracts due: Wednesday, 5 August 2026, 23:59 PM EDT (03:59 UTC) Link to session: https://agu.confex.com/agu/agu26/prelim.cgi/Session/282486 Despite being a cornerstone of modern scientific research, open-source software development and adoption often remain siloed within individual disciplines. A package or workflow designed for one discipline may elegantly solve problems in another. This session invites contributors and users of open-source scientific software from across the full breadth of AGU - from Earth's deep interior to its surface, oceans, ecosystems, and beyond into space - to share tools, workflows, and lessons learned. We welcome presentations on software that enables reproducible science, supports FAIR data principles, or integrates AI/ML approaches to accelerate discovery. A central goal is cross-disciplinary exchange: exposing the community to tools they may not encounter within their own discipline and fostering new collaborations. Submissions may address software design, community governance, interoperability with existing infrastructure, cross-disciplinary reuse, AI and LLMs, or the challenges of sustaining open-source projects. We aim to build a more connected and open science software ecosystem. Conveners : Regupathi Angappan, Ankit Barik, Miguel A.

We welcome submissions on comparative studies of Venus, Earth, and Mars, highlighting the divergent evolutionary pathways of terrestrial planets from Venus' runaway greenhouse conditions to Earth's long-term climate stability and Mars' transition from a wetter, more habitable past to its current arid state. Beyond inner planets, this Special Issue also aims to explore the icy worlds of the outer Solar System. We welcome investigations of Europa and Enceladus focusing, among other topics, on evidence for subsurface oceans, plume activity, and geophysical mechanisms that may create niches for life beneath their ice shells, as well as studies on Titan emphasizing its unique methane-based hydrological cycle, organic-rich surface, and complex interactions between the atmosphere and surface chemistry. Other icy moons are also a topic of interest for manuscripts submitted to this Special Issue. The first published papers and complete submission directions can be found at the following address: https://www.mdpi.com/journal/geosciences/special_issues/86M95CV534 21-21-21-21-21-21-21-21-21-21-21-21-21-21-21-21-21-21-21-21-21-21-21-21 Partners in Discovery: Advancing NASA Science with New Models of Commercial and University Collaboration The Commercial Space Federation, The Planetary Society, and Arizona State University will host the "Partners in Discovery" workshop, reception on August 31 and meeting days on September 1 & 2, 2026 at ASU DC. With the exception of a few programs that comprise a very small portion of NASA's budget, NASA's basic approach to supporting science hasn't changed much in the past 25 years. PI-led missions and flagships have comprised the vast majority of the mission portfolio. With NASA's recent announcements at the Ignite event and growing commercial involvement in lunar exploration, this approach is ripe for evolution. While the opportunity to drive change is great, there are fundamental questions to be addressed to enable the transition into a more aggressive commercial-university partnership mode to advance NASA Science. We seek to start answering those questions at the workshop through panels of invited speakers and time for breakout discussions amongst attendees.
