AMERICAN ASTRONOMICAL SOCIETY DIVISION FOR PLANETARY SCIENCES 2026
ADVOCACY

The American Astronomical Society (AAS) Division for Planetary Sciences
(DPS) Committee and the AAS DPS Federal Relations Subcommittee (FRS)
conducted annual advocacy visits together in April 2026. During the
visits, members of both groups met with The White House Office of
Management and Budget, NASA Science Mission Directorate Planetary
Science Division leadership, Congressional Appropriation and
Authorization committee staff, and key House and Senate member offices.
Both virtual and in person meetings were conducted to discuss ongoing
planetary science community concerns and priorities including, the need
for consistent and sustained investment in science for NASA to
accomplish the agency's robotic and human exploration goals, the
impacts of proposed FY27 cuts for NASA and NSF, and our FY27
appropriations request for both NASA and NSF.

The FRS will continue to serve as a resource for the DPS community
throughout the calendar year, and the FRS accepts new members at any
time. If you are interested in learning more about planetary science
advocacy or would like to join the FRS please contact

[EPSC2026] SESSION OPS4: SURFACE AND INTERNAL PROCESSES ON ICY MOONS -
GEOLOGICAL AND GEOPHYSICAL PERSPECTIVES

We are pleased to invite you to participate in session OPS4.

Further information & submission form at:

https://meetingorganizer.copernicus.org/EPSC2026/session/59142

Submission deadline: 13 May 2026, 13:00 CEST

Icy moons and ocean worlds across the Solar System preserve a wide
variety of geological and geomorphological features that reflect the
interaction between surface evolution and internal activity. Tectonics,
resurfacing, cryovolcanism and geomorphology provide constraints on the
structure, thermal evolution, and dynamics of ice shells, subsurface
oceans, and deep interiors. This session welcomes contributions focused
on the geology and surface processes of ocean worlds, including remote
sensing, geological mapping, structural and tectonic analyses,
geomorphology, stratigraphy, surface-atmosphere interactions, as well
as interior dynamics explored through gravity field analysis, numerical
and theoretical modelling. We encourage studies based on spacecraft
observations, remote sensing datasets, laboratory experiments, and
comparative planetology. Relevant targets include Europa, Enceladus,
Titan, Ganymede, Callisto, Triton, Pluto, and other candidate ocean
worlds. Contributions using data from past and ongoing missions, and
studies supporting future exploration by Europa Clipper, JUICE,
Dragonfly, UOP are particularly encouraged.

[EPSC2026] SESSION TP9: PLANETARY VOLCANISM, TECTONICS, AND SEISMICITY

Submission deadline: 13 May 2026, 13:00 CEST

Full details & submission link:

https://meetingorganizer.copernicus.org/EPSC2026/session/59222

Condensed session overview:

Volcanism, tectonics, and seismicity represent key expressions of
internal activity across the Solar System, fundamentally shaping the
surfaces and interiors of terrestrial planets, moons, and icy
satellites. Recent advances - including high-resolution orbital
datasets, returned lunar samples, and seismic measurements from the
Moon and Mars - have provided major insights into planetary interior
structure, lithospheric processes, and the links between magmatism,
tectonics, and seismic behaviour. Together, these observations are
transforming our understanding of how planetary bodies evolve and how
endogenic processes manifest under different physical and environmental
conditions.

This session invites contributions addressing planetary volcanism,
tectonics, and seismicity through observational, analytical,
experimental, and theoretical approaches. We welcome studies of
volcanic and tectonic landforms, magma-tectonic interactions, faulting
and lithospheric deformation, seismicity, and interior structure, as
well as numerical and laboratory modelling. Submissions on geochemical
and geophysical constraints, comparative planetology, mission concepts,
instrumentation, and data analysis related to planetary interiors and
seismic processes on planets and small bodies are particularly
encouraged.
