FRANCE WELCOMES UNITED STATES SCIENTISTS

Dear All,

Considering the situation of some scientists under the new US
administration, France is organizing a special program to welcome US
scientists who would have lost their job or would prefer to leave the
US and come to work in France. The Paris Observatory (as well as other
institutes and universities) is currently making a census of potential
candidates for this program. If you or any of your colleagues would be
potentially interested in this special program, please let me know.
Don't hesitate to forward this information to any colleague in the US
who may be in a difficult situation.

Cheers,
Coralie

AGU25 SESSION PROPOSALS NOW OPEN

This December, AGU25 returns to New Orleans, Louisiana with the theme:
Where Science Connects Us. We invite you to propose a Planetary Science
focused session.

Whether through collaborative research, innovative technologies, or
shared experiences, your session can inspire and advance our collective
understanding. Submit your proposal by 23 April.

MARS THROUGH TIME INTERNATIONAL CONFERENCE

October 14-17, 2025
Paris, France

The aim of the Mars Through Time conference is to bring together
scientists interested in understanding the past climates and
environments of Mars from the Noachian era to the present, through the
use of climate models in combination with the analysis of geological
records obtained from orbit or in situ. Go to:

MEPAG UPDATE

MEPAG has been given approval by NASA HQ to resume planning for our
spring hybrid meeting. The LPI will be reinstating MEPAG webpages,
including those hosting the meeting agenda and registration form
(required, but no fee). The agenda should be available in the next week
or two. The meeting will be held in Boulder, CO on 30 April and 1 May,
2025.

Along with the spring meeting information, you can expect to see MEPAG
webpages reposted over the next few weeks. However, at this time,
certain content will not be made available; at the spring meeting, I
will review the status of the AGs and the policies going forward
related to the MEPAG website and meetings.

As always, please feel free to e-mail me if you have any questions or
concerns (hamilton@boulder.swri.edu or victoria.hamilton@swri.org).

CALL FOR ABSTRACTS: INTERNATIONAL WORKSHIP ON INSTRUMENTATION FOR
PLANETARY MISSIONS 6

Abstract submission and indications of interest for the International
Workshop on Instrumentation for Planetary Missions 6 (IPM-2025) are now
open. Abstracts are due by May 12, and Indications of Interest are
being accepted through April 30.

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.

NASA PLANETARY DATA WORKSHOPS

The NASA Planetary Data Training Workshops project will hold a VIRTUAL
training on ASU's Java Mission-planning and Analysis for Remote Sensing
(JMARS) software on Tuesday, April 22, 2025, from 9am-1pm PDT (12-4pm
EDT). There is no registration fee for this workshop, and it will be
virtual only. JMARS is a GIS-based tool that is popular for analysis of
planetary image data, and this workshop will be geared for NEW USERS.
Please register here for this Workshop by April 15, 2025:

https://forms.gle/t4UDBTLYExtuEGvZ8

Registrants will receive the Zoom link for the Workshop several days
prior.

Note: Please register for a JMARS account and install the software on
your own computer BEFORE the workshop at:

https://jmars.mars.asu.edu/index.php?q=user/register

Any PC, Mac or Linux system and browser should work, but you will want
to verify the install works ahead of time, as there won't be time to
troubleshoot during the Workshop. If you have problems, please contact:
help@jmars.asu.edu.

2ND INTERNATIONAL CONFERENCE ON SPACE SCIENCE AND TECHNOLOGY

After the successful first conference in June 2024, the 2nd
International Conference on Space Science and Technology will be held
in Suzhou, Jiangsu Province, China from May 22 to May 24, 2025. This is
organized by "Space: Science & Technology" journal which has been
recognized by experts in the space field domestically and abroad.

This conference serves as an international forum to share the latest
development in the global space industry and to promote innovations
serving a variety of purposes in space exploration and utilization.
In addition, an overseas venue will be set up in Singapore from July
22 to July 24, 2025 to extend the conference. We look forward to
meeting international experts, scholars and industry leaders at this
conference.

serving research spanning three themes: 1) Solar System isotopes and
chronology; 2) coordinated composition, microstructure, and magnetism;
and 3) bridging the gap between remote observations and laboratory
science. We are also hiring for a post-doctoral fellow in laboratory
spectroscopy and will soon be hiring for a staff scientist position in
electron microscopy. Learn more about available instrumentation and

[NASA] PDS: MRO CRISM VRDRS

Version 1 VNIR Hyperspectral Reduced Data Record (VRDR) map tiles
include 90 spectral channels across the CRISM VNIR wavelength range and
have been assembled primarily from ~90 m/pixel VNIR hyperspectral
observations, downselected for data quality and low atmospheric
opacity, with corrections applied to mitigate noise in the data,
calibration artifacts, and effects of spatial and temporal variations
in atmospheric opacity. The VRDR map tile product suite includes
corrected spectral data, spectral summary parameter products, browse
versions of the data, and information that provides traceability to the
source observations.

These data are available at

https://pds-geosciences.wustl.edu/missions/mro/crism.htm

All available PDS data may be found at:

MENTOR BOYS & GIRLS CLUB YOUTH

NASA-funded researchers who work in extreme environments are invited to
become Mentors for the Virtual Trips to Extreme Environments (VIRTEX)
project! With training and support, Mentors act as STEM role models as
they connect with youth (ages 10-15) at a partnering Boys & Girls Club.
We're looking for NASA-funded scientists, engineers, and technicians
(including graduate students and other early career researchers) who
conduct research in exciting, "extreme" environments such as remote
field locations, unique laboratory settings, aircraft, mountain tops,
underwater laboratories, and more. We anticipate up to 7 hours of your
time, spread across several weeks. More information and applications
are at:
