PIERAZZO INTERNATIONAL STUDENT TRAVEL AWARD APPLICATIONS NOW OPEN

Each year, subject to receiving qualified applications, Planetary
Science Institute bestows two awards:

The first award supports a U.S.-based Ph.D. student to attend a
planetary science-related conference or workshop located outside the
U.S.

The second award facilitates a non-U.S.-based Ph.D. student to attend a
planetary science-related conference within the U.S. Eligible events
include planetary-focused sessions at general meetings like AGU, GSA,
EGU, and IAG. The event should be open to general participation by the
planetary community.

Each award offers a certificate and up to $2,000 in travel support, to
be presented by a PSI representative at a scientific conference or
meeting. We believe these awards can foster international collaboration
and broaden the horizons of aspiring planetary scientists.

For more information, go to:

https://www.psi.edu/pierazzo-award/

Applications close 9 PM MST, November 25, 2025 for meetings occurring
in calendar 2026. Late applications will not be accepted. Award winners
will be announced on or before December 7.

[EGU26] SESSION PS5.2: EARLY SOLAR SYSTEM - CRUCIAL TIMINGS FOR
HABITABILITY

We invite abstract submissions to the EGU 2026 session "Early Solar
System - Crucial Timings for Habitability", organised by Kristina
Kislyakova, Louis Muller, Anuja Raorane, Stephen Kane, and Tim
Lichtenberg:

https://meetingorganizer.copernicus.org/EGU26/session/56110

This session is dedicated to studies of the divergent evolution of the
Earth, Venus and Mars and the role played by the Sun. We aim to provide
a synergetic view of the evolution of the three planets, with
contributions on planetary interiors and magnetic dynamos, and
atmospheres' formation and escape being equally welcome.

The abstract submission deadline is 15 January 2026.

UT AUSTIN CENTER FOR PLANETARY SYSTEMS HABITABILITY PRIZE POSTDOCTORAL
FELLOWSHIP

The Astronomy Department and the Center for Planetary Systems
Habitability (CPSH) at the University of Texas at Austin invite
applications for an institutional prize postdoctoral fellowship. CPSH
is an interdisciplinary organization at UT Austin that seeks to advance
our understanding of planetary habitability by bringing together
members from three different Colleges within UT Austin (the College of
Natural Sciences, Jackson School of Geosciences, and Cockrell School of
Engineering):

https://habitability.utexas.edu/

We are seeking candidates with knowledge and/or interest in
habitability, broadly interpreted. Successful candidates will indicate
two mentors associated with the Center, including one from the
Department of Astronomy and another from a different department. The
ideal candidate will work on a series of projects that intersect two or
more disciplines.

The start date is September 2026. Before starting, the applicants
should have obtained a Ph.D. in Astronomy, Planetary Science, or
related field. Initial appointment is for 1 year, expected to be
renewed for up to 3 years. The deadline for applications is December
8, 2025. Application details can be found here:

https://aas.org/jobregister/ad/7c51f40c

[NASA] ROSES-25 AMENDMENT 12: F.10 PRISM STEP-1 DUE DATE TBD

The Step-1 proposal due date for F.10 PRISM is changed to TBD as a
result of the continuing government shutdown. The solicitation "close
date" shown in NSPIRES is NOT a new proposal due date; that is merely
an artefact of the NSPIRES system. When funding is reinstated,
amendments will be issued setting new due dates. We anticipate that
proposers to programs that were set to TBD will be given back as many
business days as the government was shut down.

Questions concerning F.10 PRISM may be directed to Ryan Watkins at
HQ-PRISM@mail.nasa.gov but the civil servant points of contact for this
program will not be permitted to reply until the government reopens.

NEXT EUROPLANET JUICE WEBINAR

Cassini Detects Organic Compounds in the Fresh Plume of Enceladus

5 November 2025 at 11:00 CET (10:00 UTC)

Speaker: Thomas O'Sullivan, FU Berlin

We discuss the latest detection of organic molecules in ice grains from
Enceladus, that were sampled by the Cassini spacecraft just minutes
after their ejection into the plume. These pristine grains reveal
evidence of diverse, aqueous, chemistry and could form part of larger
chemical cycles beneath the icy crust, enhancing the likelihood that
the small moon is habitable, and driving the need for future missions.
