[CMS] SESSION 8: INVESTIGATING CLAYS ON PLANETARY BODIES

The Clay Mineral Society meeting will be held July 7-11, 2026 in Provo,
Utah.

Weathering and surface processes on planetary bodies play a critical
role in the formation of phyllosilicate minerals. These minerals are
observed in meteorites and returned samples from asteroids Ryugu and
Bennu and have been characterized extensively on Mars using orbital and
in situ investigations. Laboratory analyses of Ryugu and Bennu
particles reveal Mg-rich phyllosilicates associated with carbonates,
organics, and magnetite. On Mars, smectites and other clays are found
in various locations, frequently with sulfates, iron oxides/hydroxides,
or carbonates. Remote sensing of the dwarf planet Ceres also indicates
phyllosilicates associated with NH4+, carbonates, and organics. Ocean
worlds Enceladus and Europa can host environments conducive to hydrated
silicate formation.

This session will highlight research advancements on the formation,
alteration, and preservation of clays on planetary bodies through
laboratory and spacecraft analyses and terrestrial analog experiments.
The session aims to deepen our understanding of how phyllosilicates
record the evolution of planetary environments and potential
habitability.

ESA ARCHIVAL RESEARCH VISITOR PROGRAMME

To increase the scientific return from its space science missions, ESA
welcomes applications from scientists interested in pursuing research
projects based on data publicly available in the ESA Space Science
Archives.

The ESA Archival Research Visitor Programme is open to scientists
affiliated with institutes in ESA Member States and Cooperating States
(all visits must comply with the ESA security directives, which may
necessitate additional checks). Early-career scientists, including PhD
students, are particularly encouraged to apply and so are women and
minorities. The anonymised evaluation process ensures equal
opportunities for all applicants.

During their stay, visiting scientists will have access to archives and
mission specialists for help with the retrieval, calibration, and
analysis of archival data. All areas of space research covered by ESA
science missions are supported.

Residence lasts typically 1-3 months, also distributed over multiple
visits. Research projects can be carried out at ESAC (Madrid, Spain)
and at ESTEC (Noordwijk, Netherlands). To offset the expenses incurred
by visitors, ESA covers travel costs and provides support for lodging
expenses and meals.

Applications received by 30 April 2026, 23:59 UTC, will be considered
for visits in autumn/winter 2026/2027.

[NASA] ROSES-25 AMENDMENT 49: CORRECTIONS TO C.13 SCIENCE TRANSPORT AND
ROBOTIC INNOVATION FOR DEPLOYMENT AND EXPLORATION

C.13 Science Transport and Robotic Innovation for Deployment and
Exploration (STRIDE) solicits proposals from U.S. industry to conduct
design studies of advanced robotic surface and aerial mobility systems
with payload transportation and deployment capability for Mars surface
operations, and, where applicable, early-stage prototyping of hardware
for the same purpose.

ROSES-2025 Amendment 49 makes several changes to C.13 STRIDE: in Table
C.13-1 "requirements" has been changed to page limit, In Sections 2.3,
3.3.2, and 5.1 the word "should" has been changed to "must" and,
finally, Section 3.3.2 has been clarified. New text is in bold and
deleted text is struck through. Neither Notices of Intent nor Step-1
proposals are requested for this program. The due date is unchanged:
proposals are due March 31, 2026. Updated FAQs have also been posted
under other documents on the NSPIRES page for C.13 STRIDE.

Go to:

https://solicitation.nasaprs.com/ROSES2025

The primary points of contact (POC) for C.13 STRIDE are Erica Montbach
and Lane Painter, who may be reached via HQ-STRIDE@mail.nasa.gov. The
secondary POC is Shana Faris (Contract Specialist) who may be reached
at shana.n.faris@nasa.gov.

COMMUNITY SURVEY-COSMOCHEMISTRY AND PLANETARY SCIENCE (2026)

The survey aims to capture current perspectives across the
Cosmochemistry and Planetary Science community. The results will
contribute to a forward-looking review chapter in the forthcoming book
Meteorites the Early Solar System III.

This survey is anonymous, all questions are optional, and it takes only
a few minutes to complete.

community. Thank you very much for your time and consideration.

INDICATION OF INTEREST: 9TH INTERNATIONAL PLANETARY DUNES WORKSHOP

We are beginning early planning for the 9th International Planetary
Dunes Workshop, anticipated for Winter 2028.

This meeting will mark two major milestones:

* The 20th anniversary of the first Planetary Dunes Workshop
* The 50th anniversary of the Planetary Geology Field Conference on
  Aeolian Processes

To mark the anniversary, we are proposing to host the 2028 workshop in
Southern California near the Salton Sea/Palm Springs, returning to the
area that hosted the original 1978 field conference. As with previous
Planetary Dunes Workshops, a field trip will be central to the meeting.

Because 2028 may seem far away but major planning begins early, we are
circulating a brief survey to gauge interest and identify additional
organizing committee members. If you are interested in attending or
helping to organize, please fill out the form below:

https://forms.gle/9LX1Q5a25mD2uEgx8

Please feel free to forward this message to any interested colleagues.
All are welcome and we look forward to another successful event.

WEBINAR: HOW YOU CAN SHAPE THE FEDERAL BUDGET FOR NASA

The Fiscal Year 2027 budget process is underway for the U.S. federal
budget. On February 25, the House Appropriations Committee released
its roadmap for the spending process in the lower chamber, meaning the
first major decisions about federal science funding priorities will
take place in the coming weeks.

Join The Planetary Society's Chief of Space Policy Casey Dreier and
Director of Government Relations Jack Kiraly for a webinar breaking
down the annual appropriations process, sharing what we know about the
much-anticipated President's Budget Request, and showing you how to
make your voice heard in the federal budget for NASA. This will be at
March 4, 2026 3:00 PM Eastern Time (US and Canada).

The presentation runs approximately 30 minutes, followed by live Q&A
where you can get your questions answered directly by the policy team.
