SOFFEN TRAVEL GRANT ANNOUNCEMENT

The Gerald A. Soffen Memorial Fund is pleased to announce the Spring
2026 Travel Grant application opportunity for undergraduate and
graduate students pursuing studies in fields of space science and
engineering.

The Travel Grants enable student recipients to attend professional
conferences to present their research. Recipients may use the Grant for
either virtual or in-person conferences. The Soffen Fund will award up
to $1000 in total, with no individual award greater than $500, to cover
expenses related to presenting research at either a virtual or
in-person conference. The number of awards will depend on applicants'
needs.

The Spring 2026 Travel Grant application deadline is April 17, 2026.
Jerry Soffen, a biologist by training, led a distinguished career in
NASA, including serving as the Project Scientist for Viking and as an
architect for the NASA Astrobiology Institute. The Travel Grant
continues Jerry's dedication to educating and involving future
generations in space science and engineering pursuits. The electronic
application materials and instructions are located on the Soffen Fund
website:

https://soffenfund.org

POSTDOCTORAL POSITION - PLANETARY SCIENCE

The Department of Earth and Planetary Sciences at the University of
Texas at San Antonio invites applications for a Postdoctoral Fellow
position in the Early Earth Laboratory (EEL).

Research areas include cosmochemistry, early Earth geochemistry, and
planetary systems modeling. The lab integrates quantitative modeling,
geochemical analysis, and experimental approaches to investigate the
evolution of planetary bodies and planetary systems.

Review of applications will begin April 30, 2026.

POSTDOCTORAL ASSOCIATE IN PLANETARY SURFACE PROCESSES, MIT

The Gaia Lab at MIT invites applications for a Postdoctoral Associate
in Earth and Planetary Surface Processes (Cambridge, Massachusetts).
Our research focuses on hydrological systems and landscape evolution on
Mars, Earth, and beyond, and we encourage applicants with experience in
remote sensing, data analysis (including AI/ML), numerical modeling,
and/or fieldwork. Applicants are welcome to propose research directions
aligned with their own interests. For further details and to apply,
visit:

COMMUNITY SURVEY: FIELD-BASED STUDIES & SAMPLE PROCESSING FACILITY

Scientists at Northern Arizona University are conducting a research
study gathering views from members of the planetary science community
on field-based studies and the interest in a potential centralized
facility for sample processing and analysis.

The Field Sample Processing and Analysis (Field-SPA) facility is a
concept for a centralized facility to provide baseline sample
characterization capabilities. The services offered by Field-SPA are
meant to be complementary to more specialized capabilities available
via NASA's Planetary Science Enabling Facilities (e.g., PRECISE,
RELAB, K-ALPHAA).

We are interested in learning about individual experiences, and the
barriers members of the community may face when engaging in or planning
fieldwork. We are also attempting to determine whether a centralized
facility offering sample processing and consultation services would
change the way you approach and propose field-based investigations.

All responses are anonymous and we expect this survey to take <10
minutes to complete. You can access the survey using the following
link:

If you have questions about this project or if you have a
research-related problem, you may contact Jean-Francois Smekens at
Jean-Francois.Smekens@nau.edu.

Thank you for considering participation.
