[CALL TO ACTION] ADD YOUR NAME TO SAVE NASA SCIENCE

The full White House budget proposal for FY 2026 is out, and it
decimates the NASA Science Mission Directorate. Not only are
productive, healthy spacecraft turned off, but the pipeline of new
missions, radioisotope power systems, and research opportunities are
shuttered. This is a crisis for the future of space science and
exploration.

The Planetary Society is pushing back and has launched a petition that
will go directly to Congress as part of the official budget process.
Anyone from anywhere can sign, and Congress needs to hear from you. The
more names on the petition, the more impact it will have in showing
Congress the immense public support for space science.

Add your name at:

https://planet.ly/petition

If you've already signed, consider sharing with your friends,
neighbors, and colleagues.

PLANETARY SOCIETY STATEMENT ON THE FY2026 NASA BUDGET

This budget is a retreat, a narrowing of ambition. This request
represents the smallest NASA budget since FY 1961 - a level enacted
before the first American had launched into space. Unlike that era of
growth, high ambition, and bold vision, this budget revels in the
opposite: what the nation cannot do. It claims we cannot lead the world
in deep space exploration, we cannot work with our allies, we cannot
invest in our scientific and industrial workforce. We resolutely reject
this disparaging view of our nation. NASA is a national symbol of what
we can do.

DASHBOARD: ECONOMIC IMPACT OF NASA SCIENCE ACROSS AMERICA

This new, interactive dashboard displays the breadth and scope of
benefits from NASA's science activities, with detail at the state and
congressional levels. It additionally provides custom-generated
economic impact reports for every state and impacted district,
providing detailed spending highlights and potential consequences of
the cuts. These are a great reference for outreach to congressional
representatives.

EARTH SCIENCE WOMEN'S NETWORK PROFESSIONAL DEVELOPMENT AND NETWORKING
COMMITTEE

After a successful set of events over the past four years, the Earth
Science Women's Network Professional Development and Networking
Committee (formerly Member Events) is now planning a new set of event
activities for implementation in future years from late 2025 onwards.

We know that the landscape today may feel quite different to how it
was several years ago. To ensure that our activities are aligned with
the needs and interests of the ESWN community and that they are timely,
we invite you to participate in a ~5 minutes survey (open to all) to
help us shape the program:

https://forms.gle/DyZHMhvNVzV7J5zh7

The first part of the survey collects demographic information as we
would like to know more about the ESWN community and membership, to
ensure we are creating events suitable to the needs of those we serve.

This survey will close on June 30, 2025.

We are hugely appreciative of your time and thank you for your thoughts
and contributions. If you have any questions, please email events [at]
eswnonline [dot] org

We look forward to receiving your response!

The ESWN Professional Development and Networking Committee

EUROPA CLIPPER PRESENTATION MOVED TO JUNE 17

Join the LPI for a hybrid presentation (offered in-person and
virtually) by Dr. Walter Kiefer, Director of the LPI. Dr. Kiefer will
discuss NASA's Europa Clippe0 mission and its 1.8-billion-mile journey
to Jupiter's moon, Europa. Launched in October 2024, Europa Clipper is
the first mission designed to conduct a detailed study of Europa. A
vast ocean lies beneath Europa's icy shell, and there is scientific
evidence that the ingredients for life may exist on Europa right now.

Tuesday, June 17

7:30 p.m. CT (8:30 p.m. ET / 6:30 p.m. MT / 5:30 p.m. PT)

In person or the LPI YouTube channel

POSTDOC POSITION IN ML SUPPORTED CLOUD FORMATION MODELLING

The successful candidate will be part of Prof Christiane Helling's
research group "Exoplanets: Weather & Climate" at the Space Research
Institute in Graz. The project is conducted in collaboration with Prof.
Robert Peharz from the Graz University of Technology.

In this project, we are interested in understanding cloud formation in
exoplanets and specifically the formation of molecular cluster as
pre-coursers of cloud formation in the diversity of exoplanets. We aim
to explore advanced neural network architectures, particularly Graph
Neural Networks (GNNs) and generative models, to predict the 3D
structures and thermo-chemical properties of large molecular
clusters-tasks that are computationally prohibitive using traditional
methods like Density functional theory (DFT) and molecular dynamics.
Our modelling efforts support JWST and CHEOPS in physically
interpreting observational data. We further contribute to science
case studies and science preparation for PLATO, the high-energy space
mission NewATHENA as well as HWO.

Which domain competence are we looking for:

- Astrochemistry (including carbo-hydrates),
- Cloud formation modelling (including the Solar System, exoplanets,
  brown dwarfs, AGB stars),
- Computational chemistry (including molecular cluster simulations), or
- Theoretical physics (quantum chemistry, material sciences).

ANNOUNCING MERCURY LABORATORY WORKSHOP 2025

We are excited to announce that the second edition of the Mercury
Laboratory Workshop will be held from September 15 to 17, 2025, in
Helsinki, Finland. After the success of our first workshop in Berlin
which brought together almost 60 participants, we are looking forward
to another engaging and productive workshop on our favorite planet!

The goal of this workshop is to bring together researchers, scientists,
and professionals to:

- Present recent advances in laboratory studies related to Mercury,
- Discuss key findings and ongoing research on Mercury's analogs and
  science,
- Foster collaborations and design future joint experiments and
  studies,
- Prepare for upcoming BepiColombo observations.

Registration is open until August 23!

For further details, including the registration process, abstract
submission, and last year program, please visit our website:

https://www.cosmos.esa.int/web/bepicolombo-mercury-lab-workshop/home

Additional information will be shared in the coming weeks.

For any questions, please feel free to contact Antti Penttila
(antti.i.penttila@helsinki.fi), Mikko Vuori (mikko.vuori@helsinki.fi)
and Oceane Barraud (oceane.barraud@dlr.de).

The 2025 edition is sponsored by ESA, the University of Helsinki, and
Europlanet.

We hope to see you in Helsinki for this exciting workshop!

HWO DRAFT SCIENCE CASES OPEN FOR ENDORSEMENT AND COMMENT

The Habitable Worlds Observatory (HWO) is NASA's next flagship space
telescope mission after Roman and is currently being planned. The HWO
scientific community has written 60+ Science Case Development Documents
(SCDDs) to inform HWO's science objectives and investigations. Many of
these cases focus on HWO's role in advancing Solar System science and
astrobiology. These documents are now available for public viewing,
endorsement, and comment.

To read the SCDDs and endorse or offer comments on them, please visit
the HWO 2025 conference website:
