[EDITORIAL] "E.T., PHONE THE WHITE HOUSE" OPINION ESSAY BY CASEY DREIER
IN THE NEW YORK TIMES

Casey Dreier, Chief of Space Policy at The Planetary Society, published
"E.T., Phone the White House", an opinion essay in the New York Times.

"Shattering NASA's scientific capability would be an abandonment of our
ideals: curiosity in the face of the unknown, relentless optimism and a
practical determination to engage with the world as it is, not as we
want it to be. Instead of looking up and out, we would become a country
looking down and in, the national equivalent of a teenager hunched over
an iPhone, oblivious to the world beyond."

NASA POSTDOCTORAL PROGRAM

The NASA Postdoctoral Program offers US and international scientists
the opportunity to advance their research while contributing to NASA's
scientific goals. The NPP supports fundamental science; explores the
undiscovered; promotes intellectual growth; and encourages scientific
connections.

Selected by a competitive peer-review process, NPP Fellows complete
one- to three-year Fellowship appointments that advance NASA's missions
in Earth science, planetary science, heliophysics, astrophysics,
biological and physical science, aeronautics and engineering, human
exploration systems, space operations, space technology, and
astrobiology.

Search for NPP research opportunities in planetary science here:

https://npp.orau.org/applicants/opportunities.html

Applicants must have a Ph.D. or equivalent degree in hand before
beginning the fellowship, but may apply while completing the degree
requirements. Please see current eligibility requirements at:

https://npp.orau.org/applicants/eligibility.html

Stipends start at $70,000 per year, with supplements for higher
cost-of-living areas and for certain academic specialties. Financial
assistance is available for relocation and health insurance, and
$10,000 per year is provided for travel and professional development.

Applications are accepted three times each year: March 1, July 1, and

BINARIES IN THE SOLAR SYSTEM VI - CALL FOR ABSTRACTS

We invite the community of binary asteroids scientists to submit an
abstract to the Binaries in the Solar System VI, which will take place
at the Cote d'Azur Observatory in Nice, France, from 15 to 17 September
2025. We welcome abstracts on all topics related to binary systems in
the Solar system, from their characterization (remote or in situ) to
theories on their formation and evolution.

The abstract submission is free of charge. It must be submitted on the
Abstract Submission form in a simple text format containing up to 300
words by 25 May 2025.

More information about the conference guidelines, registration, program
and practical info about the venue can be found on the meeting website:

https://bam-vi.sciencesconf.org/

Please forward this message to colleagues who may be interested.

We look forward to seeing you in Nice!

[EPSC-DPS] SESSION MITM11: SYNERGIES BETWEEN SPACE MISSIONS AND
GROUND-BASED OBSERVATIONS

Space missions to study bodies throughout the Solar System up-close
have led to significant advances in understanding how our planetary
system formed and evolved. A host of current and upcoming missions will
further revolutionise our knowledge of the Solar System's structure and
history e.g., the characterisation of numerous Jupiter Trojans by the
Lucy flybys, the Hera mission to assess the Didymos-Dimorphos system
following the DART impact, and the first ever up-close study of a long
period comet by Comet Interceptor. In addition to these small-body
missions, there are missions flying or in development to visit all the
major planets from Mercury to Jupiter, and discussions about future
missions to the ice giants. Each of these missions are greatly enhanced
by the support of ground-based facilities to provide necessary context
through remote sensing and target characterisation. This session
invites contributions from researchers undertaking telescopic
observations related to mission targets, including pre-encounter
characterisation, parallel ground and space observations, or follow up
studies.

[EPSC-DPS] SESSION ODAA6: OPEN PLANETARY SCIENCE FOR EFFECTIVE
KNOWLEDGE CO-CREATION AND DISSEMINATION

With yet another call for abstracts in the EPSC-DPS joint meeting in
Helsinki September 7-12 in this newsletter, we would like to draw your
attention to a session about Open Science.

Planetary scientists, astronomers, researchers, citizen science
practitioners, and other stakeholders are encouraged to present new
projects and the developments of previous ones, in the context of
promoting open, participatory, and public science. Science education
initiatives are also welcome.

We are looking forward to seeing presentations on efforts related to
open space/planetary science from any aspect!

The deadline is on Wednesday, May 7.

[EPSC-DPS] SESSION SB1: INTERSTELLAR OBJECTS - FROM THEORY TO
OBSERVATIONS

Interstellar objects (ISOs) have become a novel field of Galactic small
body studies, connecting the formation history of our Solar System to
the processes of planetesimal creation and evolution that play out in
planetary systems across the Milky Way.

The known population of ISOs is expected to increase soon, following
1I/`Oumuamua in 2017 and 2I/Borisov in 2019, as the planetary science
community reaps the benefits of a new generation of survey telescopes.
At the given epoch, the intrinsic ISO population remains
observationally unconstrained; theoretical predictions are equally
influential as observed physical characteristics on our understanding.

This session explores the past, present, and future research on
interstellar objects, and is therefore open to contributions from a
wide range of topics, including (but not limited to):

- Planetesimal formation and ejection mechanisms
- ISO dynamics in the Galaxy
- Evolutionary processing of small bodies e.g. in the interstellar
  medium or tidal disruption
- The relationships of Solar System populations to ISOs
- Observational characterisation of the known ISO population
- Population modelling & predictions for future ISO discoveries
- Mission concepts for in-situ ISO observation

[EPSC-DPS] SESSION TP2: ATMOSPHERES AND EXOSPHERES OF TERRESTRIAL
BODIES

EPSC-DPS 2025 abstract submissions are open until the deadline of 7 May
2025, 13:00 CEST!

We invite you to present your work in the session TP2: Atmospheres and
exospheres of Terrestrial Bodies

https://meetingorganizer.copernicus.org/EPSC-DPS2025/session/55206

Space missions have provided a wealth of data on the atmospheres and
aeronomy of rocky planets and moons, from the lower layers up to the
external envelopes in direct contact with the solar wind. This session
solicits contributions that investigate processes at work (chemistry,
energetics, dynamics, electricity, escape, surface-atmosphere
interactions, etc...) in the lower, middle and upper atmosphere of the
terrestrial bodies of the Solar System. Contributions based on analysis
of recent spacecraft and ground- based observations, comparative
planetology studies, numerical modelling and relevant laboratory
investigations are particularly welcome. In view of the three future
Venus missions selected by ESA and NASA, papers discussing contemporary
Venus atmospheric science in preparation for these missions are also
encouraged. The session will consist of invited and contributed oral
talks as well as posters.

See you in Helsinki!

Anni Maattanen, Francisco Gonzalez-Galindo, Gabriella Gilli, Orkun

Collaborative Synergies: The timely overlap of several space- and
ground-based missions may provide exciting opportunities for synergies
with NASA/ESA/CSA JWST, NASA/ESA HST, NASA TESS, ESO ground-based
facilities, and more.
