This is manifested, in one measure, by a COVID-level collapse of meetings and conferences. This and other measures will be tracked as the chaos associated with deep cuts particularly to NASA planetary research programs continues to play out in 2026 and beyond.

Stratified turbulence significantly influences the flow dynamics on various temporal scales via complex nonlinear interactions, which continue to be challenging to understand, diagnose, and quantify from both theory and numerics. This understanding is fundamental to advance our knowledge of turbulent flow dynamics, and a prerequisite for improved turbulent closures and parameterizations for robust predictions of weather and climate. Our session invites fundamental and applied contributions on stratified turbulence in fluids from theoretical, numerical, and experimental observational perspectives. The topics include, but are not limited to: two dimensional, three dimensional, isotropic, and anisotropic turbulence; regime transitions and energy cascades in turbulent flows; turbulent fluxes and transports; turbulent decay, mixing, and dissipation; stable atmospheric boundary layer flows and intermittent turbulence; wave-vortex dynamics in various turbulent regimes; wave turbulence; clear air turbulence; turbulence in weakly and strongly stratified flows and stratified shear flows. We particularly encourage participation from early career researchers. https://meetingorganizer.copernicus.org/EGU26/abstractsubmission/55800 [Edited for length] 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 [EGU26] SESSION PS1.7: ATMOSPHERES AND EXOSPHERES OF TERRESTRIAL PLANETS, SATELLITES, SMALL BODIES, AND EXOPLANETS I'm pleased to announce that the abstract submission is open for EGU 2026, held in Vienna on 3-8 May 2026 and online. The deadline for the abstract submission is 15 January 2026, 13:00 CET. Our session "Atmospheres And Exospheres of Terrestrial Planets, Satellites, Small Bodies, and Exoplanets" primarily focuses on neutral atmospheres and exospheres of terrestrial bodies other than Earth. This includes not only Venus and Mars, but also exoplanets with comparable envelopes, small bodies and satellites with dense atmospheres such as Titan, and exospheres such as Ganymede. We welcome contributions dealing with processes affecting the atmospheres of these bodies, from the surface to the exosphere. We invite abstracts concerning observations, both from Earth or from space, modelling and theoretical studies, or laboratory work. Comparative planetology abstracts will be particularly appreciated.

Cutting-edge research in recent decades has delved into characterizing life in Earth's cryosphere, understanding potential metabolic processes available to life in ice, the engineering challenges of working in and on ice, and the theoretical limits of life in various frozen environments on Earth and beyond. This session invites presentations that interrogate life in frozen environments through field, laboratory, and/or theoretical experiments across the spectrum of physical and biological sciences. This interdisciplinary session will expand our collective cryosphere acumen and encourage collaboration between fields to advance the search for life in our Solar System. Abstract submissions are due 14 January 2026 at 23:59 EDT (03:59 UTC). Thank you and we hope to see you in Madison! 8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8 [ABSCICON 2026] SESSION 43: HABITABLE SUBNEPTUNES - THEORY AND PROSPECTS FOR OBSERVATIONAL IDENTIFICATION Madison, WI USA, 17-22 May, 2026 This is a wide-ranging session embracing not just conditions for habitability of subNeptunes, but conditions that would preclude habitability and strategies for detecting such conditions (e.g. existence of magma oceans). Our invited presenters for the session are Caroline Piaulet-Ghorayeb who will discuss subNeptune atmospheric characterization, and some recent work on phase separation, and Robb Calder, who will discuss the work he and his collaborators have been doing on conditions for existence of magma oceans. Abstract submissions are now open, through 14 January.

These minerals preserve critical records of paleoenvironmental conditions, including episodic wet-dry cycles that are highly relevant to the origin, persistence, and evolution of life. Studies of terrestrial evaporite systems in extreme environments further demonstrate their capacity to shield against ultraviolet radiation and to provide microhabitats that retain moisture and protect microbial communities under harsh conditions. Consequently, evaporite-bearing environments on both Mars and Earth are prime targets for comparative planetary studies and for guiding site selection in future astrobiology-focused missions. We invite abstract submissions that: (a) Examine evaporite-rich regions on the Martian surface, (b) Characterize microbial communities and organic molecular diversity in evaporitic environments, (c) Investigate evaporite-organic interactions, and (d) Model the role of evaporites in volatile cycling and planetary habitability. https://agu.confex.com/agu/abscicon26/prelim.cgi/Session/276291 10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10 [ABSCICON 2026] SESSION 60: CHEMICAL CYCLING AND DYNAMIC HABITABILITY OF OCEAN WORLDS Ocean worlds in our Solar System are compelling targets in the search for life, offering environments where dynamic processes may sustain habitability. This session seeks abstracts that explore how geophysical and geochemical mechanisms interact to create and maintain habitable conditions in past, present, and future ocean worlds. We welcome research that advances our understanding of dynamic habitability, with an emphasis on how chemical cycling and interior processes influence the distribution and availability of the building blocks of life. Relevant contributions may include geophysical and dynamic models of ocean world interiors, investigations of chemical redox disequilibria and geochemical cycling over time, and studies of the viability and evolution of metabolic pathways. Work based on modeling, experimental simulations, analog Earth processes, and field studies of chemical transport and reactivity is encouraged. We also welcome abstracts that provide testable measurement predictions for missions such as JUICE, Europa Clipper, and Dragonfly. https://agu.confex.com/agu/abscicon26/prelim.cgi/Session/277015 Conveners: Samuel Courville, Elizabeth Spiers, Mohit Melwani Daswani, Jessica Weber 11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11 [ABSCICON 2026] SESSION 70: TURNING OCEAN WORLDS INSIDE OUT - FROM DRILLING BENEATH THE SEAFLOOR TO CRYOSPHERE SURFACES https://agu.confex.com/agu/abscicon26/prelim.cgi/Session/277012 This session spans interdisciplinary research from Earth's seafloor drilling and deep ocean environments to icy cryosphere analogues, connecting insights into the study of Ocean Worlds across planetary contexts. We invite a wide range of scientific and technological contributions that leverage seafloor sediments, hydrothermal systems, deep ocean brines, (sub)glacier environments, and ice sheets as analogues to advance our collective understanding of habitability and the search for life on other Ocean Worlds, including Europa, Enceladus, Titan, and early Mars. Key topics include: (1) physical and chemical properties of ocean and ice systems; (2) sampling techniques and technology development; (3) analog studies in marine and cryospheric settings; and (4) strategies for life detection in extreme environments. Research spanning oceanography, (micro)biology, geology, (bio)geochemistry, astrobiology, engineering, and field operations, in ocean and icy terrains is welcome, as are contributions relevant to past, ongoing, and future missions exploring Ocean Worlds in our Solar System and beyond. 12-12-12-12-12-12-12-12-12-12-12-12-12-12-12-12-12-12-12-12-12-12-12-12 [ABSCICON 2026] SESSION 96: PLANETARY CAVES AND VOIDS AS TARGETS FOR ASTROBIOLOGY SCIENCE Abstracts are due 1/14/26 This session invites contributions on all topics related to the astrobiology of caves and other subterranean planetary void spaces, including, though not limited to, detection and characterization using remote technologies, the distribution of candidate caves in our Solar System, astrobiology mission concepts, terrestrial analog studies of life in caves, characterization of biosignatures found in caves, water and rock energy sources that support microbial life in caves, and metabolic pathways of microbial communities living in caves. https://agu.confex.com/agu/abscicon26/prelim.cgi/Session/275210 13-13-13-13-13-13-13-13-13-13-13-13-13-13-13-13-13-13-13-13-13-13-13-13 [ABSCICON 2026] SESSION 97: SAMPLE COLLECTION AND HANDLING - THE CRITICAL PATH FOR ASTROBIOLOGY MISSIONS Abstracts are due 1/14/26 Many instruments exist that enable the search for life beyond Earth, but the path from sample collection to analysis is as critical as the analytical instruments themselves. Each step on that path has the potential to influence our ability to detect biosignatures, particularly for extant life, including sample collection mechanisms, the physical state of the sample and how that changes, pre-treatment of the sample prior to ingestion into an instrument, among others. Field and laboratory analog and returned sample investigations reveal how the human-decision-making process influences science returns on Earth and thus the factors we must consider in future astrobiology missions. The believability and veracity of future findings indicating extant life will depend on detailed planning and rigor in planetary protection and controlling contamination of acquired samples. We seek interdisciplinary contributions that explore technical and operational strategies that will maximize science returns by focusing on this critical mission planning step. https://agu.confex.com/agu/abscicon26/prelim.cgi/Session/276485 14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14 [COSPAR] PSW2: PLANETARY SPACE WEATHER SESSION We'd like to draw your attention to a session at the upcoming COSPAR meeting to be held in Florence, Italy, Aug 1-9, 2026 https://cospar2026.org/ PSW2: Planetary Space Weather: Significant perturbations of particle fluxes and electromagnetic fields throughout the Solar System are known as space weather effects. Being able to predict the propagation of such effects and their impacts on various planetary environments, and to design missions around the study of these effects, is crucial for successful planetary explorations. We invite descriptions of space weather effect measurements in interplanetary space or planetary environments, as well as models, comparisons, and methods that aid in understanding the fundamental plasma processes and improving predictions. Moreover, we welcome the presentations that explore how the space weather environment at Solar System bodies affects the design criteria for instruments and missions in exploratory programs. In addition, we also encourage presentations that examine the topic of planetary space weather in the context of COSPAR space weather roadmap development. The abstract submission deadline is February 13, 2026. https://www.cospar-assembly.org/admin/session_cospar.php?session=1545 Best Wishes, Insoo Jun, Junjie Chen, Christina Plainaki, Roksoon Kim, and Leila Mays 15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15 3-YEAR POSTDOCTORAL POSITION IN MARS GLACIOLOGY AT SHEFFIELD UK A reminder that we are hiring a 3-year postdoctoral research associate in Mars glaciology at the University of Sheffield in the UK.

Three core community surveys and one General Astrophysics Survey (GAS) have already been designed. Details can be found at: https://roman.gsfc.nasa.gov/ The Cycle1 call for proposals solicits for: Analysis of Roman data, new GASs, theory and laboratory astrophysics, public ancillary data analysis and TOOs. It is due March 17th. While all the current surveys will produce data for Solar System science, none are specifically designed for such. The Exoplanets and Solar System (SS) Working Group leads invite you to participate in discussion for proposal designs and preparation, which are differently structured than typical space-telescope calls. For new datasets science applications outside Exoplanet and SS are important factors and the data have NO proprietary period. For analysis we desire input from the community to learn both what tools might already exist/can be adapted, and what tools need to be developed. We meet the 1st Tuesday of each month and invite you to join us. Our next meeting is 13 January 2026 from 3-4pm EST at: https://osu.zoom.us/j/93405766421?pwd=sEKhbq64QfBcjv7fn62rHZsb67LvNn.1 If you want to connect before our next meeting or have questions, please contact: Susan Benecchi, susank@psi.edu SS/Exoplanet Working group co-lead 19-19-19-19-19-19-19-19-19-19-19-19-19-19-19-19-19-19-19-19-19-19-19-19 SAVE THE DATE: THE NEXT GENERATION OF IO SCIENCE WORKSHOP Io is the most volcanically active world in the Solar System, yet fundamental questions persist regarding its origin, evolution, present-day activity, dynamic atmosphere, and its complex interactions with the rest of the Jovian system. Io's extreme activity makes it an important analog for understanding processes relevant to the early Earth and Moon, and other tidally heated worlds across the cosmos. The Next Generation of Io Science Workshop will be held from 4/22/26 to 4/23/26. The Workshop will be hybrid, with both in-person participation at the Applied Physics Laboratory (Laurel, MD) and online. Participation is free. Short abstracts are requested by 3/6/26. The goal of this workshop is to bring together interdisciplinary scientists to discuss outstanding science questions about Io. We solicit participation from the broad community-whether you have worked on Io before or not! The meeting will include a combination of contributed talks, lightning talks (ideal for sharing new ideas or raising questions), and discussion about next steps for Io science.
