NOTICE OF ONGOING REMOVAL OF SCIENCE PROGRAM AND AG DOCUMENTS BY LPI

All community members should be aware that the Lunar 
and Planetary Institute (LPI) has been removing links to and mention 
of conference abstracts and Assessment/Analysis Group (AG) documents 
from past years if they included statements about diversity, equity, 
inclusion, accessibility or other related workforce issues - including 
the full workforce session that was just solicited for and held at the 
2025 LPSC.

The ADS/SciX team has identified around 1,000 broken links. This 
removal by LPI had been done quietly, with no notice to affected 
persons and no explanation until a brief email sent on May 8.

The documents held by LPI constitute a vital record of past work in 
research, community development, and consensus building that needs to 
be available for current and future researchers. Their removal is a 
violation of individual and collective intellectual record and of our 
community trust.

Community-led efforts are underway to preserve this record, such as by 
the Astrophysics Data System/Science Explorer (ADS/SciX) team. If you 
discover a broken link to your LPI abstract or other scientific 
publication, email help@scixplorer.org so that they can investigate 
and, if possible, restore access to the content.

MESSAGE TO THE MEPAG COMMUNITY

I understand that this is a time of great stress and frustration for 
our community. But as I said at our hybrid meeting just days ago, it 
is important now, more than ever, that we treat each other with 
respect and dignity. This includes, for example, our interactions with 
colleagues at NASA Headquarters and the Lunar and Planetary Institute. 
If you have concerns about a specific issue, please express those 
concerns in the way that you would want to be approached. There is no 
excuse for sending hate mail to anyone, but especially not the people 
who are not responsible for a policy with which you may disagree. I 
believe we are all better than that and we will make our way through a 
changing landscape by working together, not attacking each other.

POST-DOC POSITION AT UNIVERSITY OF CENTRAL FLORIDA

The Mc Keown Group in the University of Central Florida (UCF) 
Department of Physics in the College of Sciences seeks to hire a 
Postdoctoral Scholar to help set up the new FROSTIE lab, aimed at 
investigating icy planetary surface processes under simulated 
planetary conditions. The postdoctoral scholar will have the 
opportunity to research icy geomorphological signatures of seasonal 
processes on Mars and transient liquid water activity relevant for 
icy airless worlds. The successful candidate will lead design, 
integration and testing of cryo-vacuum regulation and data acquisition 
systems. Experience working with cryogenic thermal-vacuum systems is 
necessary. The scholar's technical expertise will be integral to the 
successful completion of cutting-edge experiments investigating the 
roles of ice sublimation and endogenic liquid water activity in 
modifying the surfaces of Mars, Europa and small bodies. The scholar 
would begin the position as soon as possible and serve for 24 months, 
extendable upon the availability of funds and mutual agreement of the 
scholar and the supervisor.

PLANETARY DATA MANAGEMENT TRAINING

Planetary Data Management Workshop - A virtual, one-day training event 
on June 16, 2025 focused on archiving common planetary science 
datasets outside of the PDS, openly available tools, and data 
management best practices. This applied workshop addresses SPD-41a 
requirements, organizing of common data types, metadata creation, peer 
reviews, and data repositories. Class size is limited to 30 
participants; please register here:

IMPACTS AND THEIR ROLE IN THE EVOLUTION OF LIFE CONFERENCE

The meeting will take place from 1 to 4 September 2025 in the 
picturesque medieval city of Nordlingen, which is situated inside the 
world-famous Ries crater in southern Germany. It aims to cover the 
role of meteorite and comets impacts in the formation of Earth, its 
atmosphere and the evolution of life. The conference will consist of 
lectures, discussions, excursions, and poster sessions. The European 
Astrobiology Institute and the Stockholm University Astrobiology 
Centre, and the University of Neu-Ulm will function as co-organisers 
of the conference.

- Impacts and the early history of the Solar System
- Impact structures as indicators of target properties
- Role of impacts in delivery and formation of the building blocks for 
  life
- Impact-generated habitats for life
- Environment effects of impacts
- Impacts as threats for life and humankind
- Geoconservation, education and outreach of impacts

We also will have two one-day excursions, one around the Ries crater 
on 4 September and one half-day excursion on 2 September to the 
Steinheim crater with its famous central uplift feature.

Submit abstracts by 31 May 2025.

Registration deadline is 30 June 2025.

ABSTRACT DEADLINE EXTENSION: INTERNATIONAL WORKSHOP ON INSTRUMENTATION 
FOR PLANETARY MISSIONS 6

The abstract submission deadline for the International Workshop on 
Instrumentation for Planetary Missions 6 (IPM-2025) has been slightly 
extended from May 12 until midnight (MT) May 16. 

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.

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:
