NEW HORIZONS SCIENCE SPOTLIGHT WEBINAR

Join us on 24 April 2025, 2:30-3pm EDT (11:30-12 PDT,12:30-1pm MDT,
1:30-2pm CDT)

New Horizons continues its operation, now at 61au from the Sun. Since
2015 it has made ground-breaking discoveries of the Pluto-Charon
system, flown past the small contact KBO binary Arrokoth and collected
phase and light curve data for some three dozen additional KBOs and the
ice giants. It has also been sampling dust density throughout the Solar
System and studying the cosmic optical background. To raise awareness
of New Horizon's scientific impact we are beginning a new spotlight
seminar series (30 min, fourth week each month) which we invite you to
attend online, or watch recorded at your convenience.

Our speaker will be Al Emran, JPL, and he will be speaking on:
"Kiladze Caldera: A Possible Cryovolcano on Pluto"

2025 DPS TRAVEL GRANT APPLICATION FORM IS OPEN

The DPS Travel Grant application is open to support participation in
the EPSC-DPS2025 meeting in Helsinki, Finland, 7-12 September 2025, or
the National Society of Black Physicists-National Society of Hispanics
Physicists annual meeting.

The Hartmann Student Travel Grant supports student presentations at the
joint DPS-EPSC meeting (postdoctoral scholars are eligible at lower
priority). The Underrepresented Minority (URM) Communities in
Planetary Science Travel Grant supports attendance at the joint
DPS-EPSC or joint NSBP-NSHP meeting by students and professionals who
are members of groups that historically have had lesser involvement in
planetary science, to foster wider access. Applications are especially
encouraged from members of group(s) whose contributions to STEM may
have been overlooked, students and professionals from non-R1 academic
or research institutions that have not traditionally benefited from
connections to planetary science, and/or students and professionals
with degrees in broader STEM disciplines who are new to planetary
science (these include but not limited to small, primarily
undergraduate colleges and universities, and minority serving
institutions).

Apply at:

https://dps.aas.org/news/dps-travel-grants-application/

The deadline is 3 July.

Members of Europlanet should apply for Europlanet awards through the
abstract submission form.

[EPSC-DPS] SESSION EXOA13: BRIDGING GEOSCIENCES AND ASTRONOMY TO
INTERPRET ROCKY (EXO)PLANET OBSERVATIONS

The coming years will be revolutionary for rocky planet research, with
JWST, ELT, ARIEL, and PLATO providing unprecedented observations of
rocky exoplanets in our galaxy. At the same time, BepiColombo, the
Mars sample return mission, and the Decade of Venus missions will
greatly enhance our understanding of the rocky bodies within the
Solar System. This session aims to bring together scientists from
astronomy, geosciences, and planetary sciences, to explore how
interior-atmosphere interaction shapes rocky (exo)planet surfaces and
atmospheres. We welcome contributions spanning experimental work,
observational efforts, and modelling studies. By combining insights
from exoplanets, which serve as a natural laboratory for rocky world
diversity, and Solar System planets, which provide the detailed
observations needed to build and validate models, we can develop a
robust framework for interpreting observations of any rocky body. We
encourage discussions that span all related fields, fostering new
collaborative approaches to studying rocky planet evolution.

Submit abstracts (deadline May 7):
