RELEASE OF PLANETMAGFIELDS WEB APP

Some time ago, I wrote an open-source package planetMagFields to
consolidate planetary magnetic field models in one place, and offer
easy access API to visualize and analyze them:

https://ankitbarik.github.io/planetMagFields/

With great pleasure, I am happy to announce the release of the
planetMagFields Web App:

https://planetmagfields.streamlit.app/

With this you can:
- Visualize planetary magnetic fields in 3D (including that of Earth
  going back to 1900 using IGRF)
- Visualize their fields at various radii
- Plot their spectra, and last but definitely not the least
- Provide an orbit trajectory and obtain the field components along the
  trajectory.
- As a bonus, it also provides links to the publications for the field
  models. :)

Give this a try and please reach out to me at abarik@jhu.edu or submit
issues on GitHub for any questions or feature requests! I hope this can
be a useful tool, especially for teaching.

BE THE SCIENTIST WHO INSPIRES THE FUTURE: BECOME A VIRTEX MENTOR!

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? Apply today at:

Session Link:

https://agu.confex.com/agu/agu26/prelim.cgi/Session/279867

If we decide in the future to create sustainable habitats and
ecosystems beyond Earth, enlarging our environmental responsibilities,
then science will have a critical role to play. 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.

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

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.

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.

The conveners: Leslie Tamppari (JPL), Jeffrey Plaut (JPL), Ernst Hauber
(DLR), and Ingrid Daubar (Brown)

[GSA 2026] SESSION T188: GEOMORPHOLOGY AND SURFACE PROCESSES ACROSS
THE SOLAR SYSTEM

If you plan on attending the 2026 Geological Society of America
Connects Meeting in Denver, Colorado (October 11-14, 2025), we
encourage you to consider submitting an abstract to session T188:
Geomorphology and Surface Processes Across the Solar System.

This session welcomes abstracts on any aspect of planetary
geomorphology and surface processes, including but not restricted to:
Earth analogues, laboratory experiments, numerical models, planetary
comparison, mapping, in situ data, or remote sensing studies.

The session brings together researchers studying Earth and other
planetary bodies to compare how geomorphic processes operate across
different environmental conditions. By fostering dialogue between
terrestrial and planetary scientists, it promotes cross-system insight
into the fundamental mechanisms that shape landscapes throughout the
Solar System.

We are also excited to have two excellent invited speakers: An Li
(University of Washington) and Harrison Martin (Caltech).

The abstract portal is open and can be accessed here:

https://gsameetings.secure-platform.com/connects26

COMMERCIAL: LETTERS OF SUPPORT REQUEST

Potomac Database Systems ("Potomac" potomacdb.com) is innovating a new
commercial paradigm for lunar surface data collection and access.
"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. To learn more and indicate
potential, no-obligation interest in signing, click here:
