[GSA 2025] SESSION T163: EXPLORING THE DIVERSITY OF VOLCANISM IN THE
SOLAR SYSTEM

The Fall 2025 Geological Society of America (GSA) meeting features
numerous sessions focused on planetary science. We would like to
announce our selected session titled "Exploring the Diversity of
Volcanism in the Solar System" (T163). From cryovolcanic plumes on
Europa and active lava lakes on Io to the enigmatic Venusian pancake
domes and everything in between, volcanism is a fundamental geologic
process that occurs throughout the Solar System in a diversity of
forms. This broad session invites abstracts that present recent
advances in modeling and quantifying volcanic processes throughout the
Solar System. Abstracts focused on the destinations of upcoming
planetary missions are encouraged.

Abstract submission opens 1 May 2025 and closes 5 August 2025. If you
have any questions, please contact the session conveners: Sean I.
Peters (seanp@middlebury.edu) and Ian T.W. Flynn (itf2@pitt.edu).

THREE PHD POSITIONS IN SPACE PHYSICS AT UMEA UNIVERSITY, SWEDEN

The Department of Physics at Umea University, Sweden, invites
applications for three PhD positions in space physics. These positions
involve advanced numerical simulations and analysis of spacecraft data.
The positions are full-time and 100% funded for four years. The
expected start date is September 1, 2025, or as agreed. The application
deadline is May 23, 2025.

The three PhD projects are:

Project 1: Plasma interaction with Mercury's magnetosphere
Project 2: Ganymede's aurora
Project 3: Water plumes of the icy moons

[NASA] EONS-2025 NOTICE OF FUNDING OPPORTUNITY

This National Aeronautics and Space Administration (NASA) Notice of
Funding Opportunity (NOFO) entitled Engagement Opportunities in NASA
STEM (EONS) - 2025, solicits proposals for competitive funding
opportunities in support of the programs administered by NASA's Office
of STEM Engagement (OSTEM). Go to:

https://tinyurl.com/crcr8wur

EONS-2025 is an omnibus announcement that includes a wide range of NASA
STEM Engagement opportunities for basic and applied science and
technology research and education to support workforce development.
Specific opportunities will be issued periodically throughout the year
as Appendices to this solicitation with individual requirements and
milestones.

[EPSC-DPS 2025] SESSION ODAA3: DIVERSITY AND INCLUSIVENESS IN PLANETARY
SCIENCES

The benefits of diversity and inclusiveness in the scientific community
are incontrovertible. Following the success of previous years, this
session aims to foster debate within the planetary sciences community
about the reasons behind the under-representation of different groups
(gender, cultural, ethnic origin, and national) and best practices to
make the research environment more inclusive identifying and addressing
barriers to equality.

We invite abstracts focusing on under-representation (gender, cultural,
ethnic origin, and nationality biases) supported by statistics and
data; outreach and education activities to reach broad and diverse
audiences, best practices to support inclusiveness; and case studies on
mentoring and bias-concerned activities.

Please, submit you abstract here:

https://meetingorganizer.copernicus.org/EPSC-DPS2025/session/55160

The deadline abstract submission is 7 May 2025, 13:00 CEST

We look forward to welcoming you in Helsinki in September, and online!

The conveners:

Arianna Piccialli, Solmaz Adeli, James Roberts, Jarita Holbrook

ABSTRACT DEADLINE REMINDER: INTERNATIONAL WORKSHOP ON INSTRUMENTATION
FOR PLANETARY MISSIONS 6

This is a reminder that the abstract submission deadline for the
International Workshop on Instrumentation for Planetary Missions 6
(IPM-2025) is approaching, with a final deadline of May 12.

We are soliciting abstracts that address lessons learned from previous
planetary instruments, a survey of current state-of-the-art
instruments and enabling technologies (including software), and
emerging capabilities in planetary instrumentation. The IPM-2025 will
be held August 4-6, 2025, in Boulder, Colorado. A remote attendance
option will be provided, although presenting authors must attend in
person. For more information, go to:

JOIN US FOR A PUBLIC EVENT: EXPLORING EUROPA

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 Clipper 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.

Thursday, June 5
