For many of adolescents, personally knowing a scientist is a rare opportunity. You can change that. "As a scientist who works with other scientists, it's easy to take for granted being 'on the inside' of what so many other curious, scientifically-minded people wish they could access. In my interactions with the Boys and Girls Clubs, I realized many students don't have that encouraging, supportive, educational immersion. It was a joy to be a personal touch point into space science for those students." - VIRTEX Mentor Dr. Kirby Runyon The VIRTEX (Virtual Trips to Extreme Environments) program, sponsored by NASA's Office of STEM Engagement, is looking for NASA-funded researchers to serve as virtual mentors to middle school students at youth-serving organizations. Minimal Time Commitment: 5 hours. Who: Anyone conducting (or who has conducted) NASA-funded research or efforts. What You'll Share: Casual, virtual conversations about your career journey. How it Works: Sessions are held virtually during summer or afterschool hours. Your personal contact information is never shared. Compensation: Mentoring is voluntary. Limited professional fees are available for early-career researchers. Ready to become a catalyst for positive change?

As the cost of access to space continues to fall, a fresh look at the research agenda for creating sustainable habitats and ecosystems is timely and necessary. We encourage contributions on all aspects of either local terraforming or global terraforming on or beyond Earth, including planetary atmospheres, climate modeling and climate feedbacks, monitoring of climate change beyond Earth, spacecraft data analysis, hydrology, soil/regolith composition, soil and regolith characterization and remediation for biological suitability, biogeochemistry, in-situ resource utilization for environmental control and life-support, oxygen production, ecology, and space physics, as well as the exploration and distribution of terraforming-relevant resources. Submissions on technologies and techniques that support applied astrobiology goals are particularly encouraged. Conveners: Edwin Kite, Nils Averesch, and Chuanfei Dong 19-19-19-19-19-19-19-19-19-19-19-19-19-19-19-19-19-19-19-19-19-19-19-19 [AGU 2026] SESSION P016: MARS SURFACE STORIES - GEOLOGY, MINERALOGY, GEOCHEMISTRY Abstracts due: Wednesday, 5 August 2026, 23:59 PM EDT (03:59 UTC) Session Link: https://agu.confex.com/agu/agu26/prelim.cgi/Session/283492 This session will highlight recent advances in understanding the surface of Mars through integrated presentations about the planet's geology, mineralogy, and geochemistry. It will bring together results from orbital, landed, roving, laboratory, and analog investigations to reconstruct surface processes, identify key mineral assemblages, and interpret the chemical histories recorded in Martian rocks and regolith. Contributions may address sedimentary, volcanic, and alteration environments; links between mineralogy and habitability; terrestrial analog studies and field sites; and implications for Mars' climatic and aqueous evolution. By combining observations across scales and techniques, the session aims to sharpen our view of how Mars' surface has evolved through time and where the most informative records of those changes might still be preserved. Conveners: Jim Bell, Briony Horgan, Alicia Vaughan 20-20-20-20-20-20-20-20-20-20-20-20-20-20-20-20-20-20-20-20-20-20-20-20 [AGU 2026] SESSION P026: STARS TO EXOPLANETS, SUN TO EARTH - BRIDGING DISCIPLINES IN SEARCH OF HABITABILITY Abstracts due: Wednesday, 5 August 2026, 23:59 PM EDT (03:59 UTC) Session Link: https://agu.confex.com/agu/agu26/prelim.cgi/Session/281371 The research of all four of NASA's science divisions provides critical insights into the formation and evolution of planetary systems, particularly those that may be capable of supporting life. Working across these science divisions is a must for the community to make forward progress. In this session, we seek to highlight work that demonstrates that interdisciplinary ideal. We want to hear about your laboratory experiments, theoretical studies, modeling efforts, and observations. Whether your work applies lessons learned from old contexts to new (e.g., Earth biology and planetary evolution to exoplanets broadly), or takes a novel approach to characterizing exoplanet systems and their potential to harbor life, we want to hear from you. This session is sponsored by NASA's Nexus for Exoplanet System Science (NExSS), a research coordination network aimed at fostering communication and collaboration across disciplines in exoplanet research. Early career researchers are especially encouraged to showcase their work. The conveners: Ofer Cohen (Mass Lowell), Linda Sohl (NASA GISS), and Hilairy Hartnett (UW) 21-21-21-21-21-21-21-21-21-21-21-21-21-21-21-21-21-21-21-21-21-21-21-21 [AGU 2026] SESSION P032: THE SURFACE AND SUBSURFACE OF MARS AS SEEN FROM ORBIT Abstracts due: Wednesday, 5 August 2026, 23:59 PM EDT (03:59 UTC) Session Link: https://agu.confex.com/agu/agu26/prelim.cgi/Session/283502 Several orbiting spacecraft are celebrating their many years continuously acquiring data of the surface and subsurface of Mars. Odyssey has been in orbit 25 years, MRO and Mars Express for over 20 years, and TGO for 10 years. These orbiters, along with many others throughout time, have acquired a rich interdisciplinary dataset from which to learn about current and past processes on Mars, with the aim of unraveling its geologic, climatic, and evolutionary history in comparison to Earth and other planets. This session invites submissions on all aspects of martian surface and subsurface processes, their interactions with the environment, and their changes in time, with emphasis on interdisciplinary science.

"Pathfinders," instrumented lunar surface impact penetrators, will provide geophysical data across the Moon from seismometry to regolith and volatile composition. These unique data will be available on the web app, Nexus, hosted by Potomac. Potomac is seeking non-binding letters of support from scientists who believe commercial lunar data should be more accessible, affordable, and useful to the global Moon community.
