IN MEMORIAM: LINDA FRENCH (1951-2025)

Dr. Linda M. French, 74, died on November 9, 2025 in Exeter, NH.

Linda received her PhD (1980) in Astronomy from Cornell University.
Involved in research on the shapes, spin states, and surface
compositions of small Solar System bodies, she emphasized the
properties of Trojan asteroids in an effort to understand their
origins. From 2017-2019, she worked as Program Director, NSF
Astronomical Sciences Division. Linda served as Education Officer
(1993-1997), Secretary (2003-2006), and Education Advisory Board member
(2008-2010), Division for Planetary Sciences, American Astronomical
Society.

A dedicated educator, Linda taught astronomy, physics, and life
sciences to students of all ages throughout her career. She spent the
last two decades of her professional life as a professor at Illinois
Wesleyan University, receiving the Kemp Foundation Award for Teaching
Excellence in 2016. She also developed and taught a popular course on
the music of the Beatles as part of IWU's freshman writing program.

Linda made numerous trips to York, England, to research the life of
18th-century astronomer John Goodricke. She served on the AAS
Historical Astronomy Division Committee (2012-2015).

In 1988, asteroid (3506) French was named in her honor; in 2020, she
was named an AAS Legacy Fellow.

LETTER FROM THE NASA PLANETARY SCIENCE DIVISION DIRECTOR: THE FUTURE
OF PLANETARY SCIENCE ANALYSIS AND ASSESSMENT GROUPS

The NASA Planetary Science Division (PSD) will now formally no longer
be supporting the Assessment Groups (AGs). For more information see the
letter from NASA Planetary Science Division Director Louise Prockter.

[NASA] ROSES-25 AMENDMENT 36: NEW PROGRAM ELEMENT - F.19 COLLABORATIVE
OPPORTUNITIES FOR MENTORSHIP, PARTNERSHIP AND ACADEMIC SUCCESS IN
SCIENCE

F.19 Collaborative Opportunities for Mentorship, Partnership and
Academic Success in Science (COMPASS) funds collaborations between NASA
Centers and academic institutions that will advance NASA's scientific
priorities and train the future STEM workforce. COMPASS prioritizes
collaborations with academic institutions that have not traditionally
been funded by NASA as part of an effort to provide funding to a broad
range of recipients rather than to a select group of repeat players.
COMPASS prioritizes research that reflect NASA and the Administration's
priorities and advance the Science Mission Directorate and NASA's
research goals. COMPASS creates undergraduate and graduate student
research opportunities that provide professional development
opportunities for students that help to build the United States' STEM
workforce.

ROSES-2025 Amendment 36 presents a new program element in ROSES-2025.
Notices of Intent are not requested. Proposals are due by March 20,
2026. Go to:

AXISEM3D SEISMIC MODELLING COMMUNITY MEETING

Register now for the first AxiSEM3D Community Development Workshop,
April 13-14 in Pasadena, California. This meeting will involve
discussions of the AxiSEM3D family of codes for seismic modelling,
with planetary science as a novel focus area. The meeting is free to
attend and is open to any developer, user or potential user of the
AxiSEM3D seismic modeling code (or its precursor AxiSEM).

ANNOUNCING THE NEW ISSUE OF SCIENCE ASCEND

Science Ascend (ISSN: 3062-0090) is an astrophysics journal in the
English language with discussions on cutting-edge astrophysics
research, tools, and interviews with people from the private sector and
universities. It is a non-peer-reviewed, free-to-submit, and
free-to-read journal published by FIRE Research and Training Ltd.

The current issue (Volume 3 Issue 1, January-June 2026) has:

- Two interview notes with Evgeny Smirnov (4xxi/Denovo, United Kingdom)
  and Professor Ozlem Yesiltas (Gazi University, Turkiye),
- A science outreach case observation on the Astrobot JWST account in
  BlueSky by Guray Hatipoglu (FIRE Research and Training Ltd.),
- An article on Venus, its clouds and sulphur by Maarten Roos-Serote
  (Lightcurve Films, Portugal),
- A descriptive article on Cosmic Strings as relics of the early
  universe by Professor Ozlem Yesiltas, followed by
- A description of Singular Spectrum Analysis (SSA) and some of its
  most used modifications, as well as a review of astronomy papers from
  2025 that utilized SSA by Guray Hatipoglu.

Anyone can freely read the current issue at the following link (along
with previous issues):
