PLANETARY SCIENCE JOURNAL SCIENCE EDITOR

Established in 2020, the American Astronomical Society's (AAS)
Planetary Science Journal (PSJ) has grown to one of the most impactful
journals focused on planetary science in the world.

To continue that upward trajectory, the PSJ solicits applications to
join the team of Scientific Editors (SEs). AAS SEs are expected to
comply with the AAS Code of Ethics and commit about 10% full-time
equivalent effort to their work for the Journals. Scientific Editors
receive a grant of approximately $15,000 per annum for their services,
plus travel support for the annual meeting.

To apply, submit a CV and 2-3 page cover letter describing your
interest in the role and your related experience to the incoming PSJ
Editor-in-Charge, Brian Jackson (brian.jackson@aasjournals.org).

[ABSCICON 2026] SESSION 04: DATA-DRIVEN ASTROBIOLOGY - INTEGRATING THE
FOUNDATIONS FOR AI AND ML

Abstract Deadline: 23:59 EST/03:59 UTC on 14 January 2026.

Session Link:

https://agu.confex.com/agu/abscicon26/prelim.cgi/Session/277054

Astrobiology relies on an extraordinary diversity of data, from field
analogs and laboratory experiments to mission observations and modeling
efforts. As Artificial Intelligence (AI) and Machine Learning (ML)
approaches become central to discovery, linking these diverse datasets
is essential for revealing the broader patterns that shape planetary
habitability and the potential for life. This session focuses on how
data collection, integration, and cross-disciplinary frameworks enable
new insights in astrobiology. We welcome submissions on the current
astrobiology data ecosystem, new and existing data repositories
relevant to the community, ontologies and other organizational
schemes, metadata standard development, practices for hosting and
sharing data, tools relevant to mining or working with existing
astrobiology data, managing multi-modal datasets, and projects that
have made notable or creative use of astrobiology open science
resources.

[NASA] ROSES-25 AMENDMENT 24: F.10 PRISM DUE DATES RESET AND OTHER
CHANGES

This Amendment defers three dates for this program element: The
pre-proposal webinar will occur December 5, 2025, at 1 pm Eastern Time,
see the PPC connect information in Section 9; Step-1 proposals are now
due December 12, 2025; and Step-2 proposals are now due February 20,
2026. Moreover, a few other changes were made: In Section 2.1 a
paragraph about the direct purchase of goods, supplies and/or services
from non-U.S. sources was expanded; small changes were made to Section
3.1 to provide updated guidance on landing site hazard analyses; and a
paragraph referring to cooperative agreements as the award type was
removed from Section 5. New text is in bold, deleted text is struck
through. FAQs will be posted shortly under "Other documents" on the
right side of the NSPIRES page for F.10 PRISM. Go to:

[AOGS 2026] SESSION PS07: ADVANCES IN SMALL BODIES SCIENCE

Meeting site:

https://www.asiaoceania.org/aogs2026

Dates: August 2-7, 2026
Venue: Fukuoka International Congress Center, Japan

Submission Deadline: January 23, 2026.
Instruction:

https://tinyurl.com/55h8hsfh (shortened)

This session offers a comprehensive forum for research on small
bodies throughout and beyond our Solar System, including asteroids,
comets, KBOs, irregular satellites, meteoroids, and interstellar
objects.

We invite presentations covering all methodologies in small-body
science, including observations, spacecraft missions, laboratory
experiments, and theoretical modeling. Contributions on future mission
prospects, deep all-sky surveys, and planetary defense projects are
also welcome.

Our goal is to highlight the latest and most significant advancements
in small-body research worldwide, with a special focus on developments
from the Asia-Oceania region, and to foster international
collaboration.

We look forward to your active abstract submissions.

Sincerely,

Toshihiro Kasuga, Takafumi Ootsubo, and Man-To Hui

PHD AND POSTDOC OPPORTUNITIES AT THE UNIVERSITY OF BERN: EXPLORING
ABIOTIC ORGANIC COMPLEXITY

The Space Research and Planetary Sciences Division at the University of
Bern is offering two PhD positions and one PostDoc position focused on
analysing legacy data from ESA's Rosetta mission to comet
67P/Churyumov-Gerasimenko. These positions are dedicated to the
data-driven investigation of cometary abiotic organic complexity (AOC)
based on highly convolved high-resolution mass spectra, with the goal
of developing a reference framework for future space missions,
including those searching for signs of extraterrestrial life.

Working within an interdisciplinary team that combines astrobiology
with analytical chemistry (namely, mass spectrometry) and data science,
successful candidates will systematically inventory prebiotic molecular
signatures or develop data-analysis pipelines that integrate
chemometrics/multivariate statistics and scientific machine learning to
enable an unbiased, data-driven characterization of cometary AOC.

MAHLI TECHNICAL REPORT RELEASED

The Mars Handlens Imager (MAHLI) instrument onboard the Mars Science
Laboratory (MSL) Curiosity rover releases Technical Reports at
relatively regular intervals. These reports are designed for the
non-MSL team member to be able to see what observations MAHLI has
acquired, and what the rationale was for taking them. These are
searchable word docs, so a target name is sufficient to isolate where
the MAHLI image was taken and when, as well as the associated technical
info (picture number, etc.).

MAHLI Tech Rept 0040 - Sols 4355-4488, is released. These are data that
were released to the public via NASA PDS. The Tech Report can be found
on both Zenodo and Research Gate.

EUROPLANET WEBINAR: ABOUT VENUS, CLOUDS AND SULPHUR - FRESH RESILTS AND
WHAT INSIGHTS THEY MIGHT BRING

The sulphur cycle in the atmosphere of Venus has been object of study
for many years. Our speakers Therese Encrenaz (Paris Observatory) and
Rakesh Mogul (California State Polytechnic University) recently
published brand new results that feed new information into this study.
Therese Encrenaz has been observing Venus for decades from Earth and
she will provide with an overview of her findings. Rakesh Mogul
re-analysed Pioneer Venus descent probe data and discovered new
information about the chemical composition of the sulpheric acid cloud
particles. Join us in this 75 minutes long get-together listening to
these new findings, and participating in the open informal discussion
that will follow to share your thoughts on this enigmatic topic.

This webinar will be in normal-Zoom-mode, with all attendees being able
to have video and audio if they wish. Both speakers will present for 25
minutes. After that we have 25 minutes time for discussion about the
topic among all the participants. Please bring your ideas and thoughts
on the topic and let's engage in an interactive and constructive
scientific discussion!
