PEN PROVIDING LINKS TO DIAMOND OPEN ACCESS ARTICLES IN THE NEW JOURNAL
PLANETARY RESEARCH
For the past six years, PEN has carried direct links to new papers
published in the open access Planetary Science Journal. In late 2024,
we expanded our service to provide direct links to open access
articles in Journal of Geophysical Research: Planets. We will now be
providing direct links to articles in the new journal, Planetary
Research. As a diamond open access journal there are no page charges
for authors nor access charges for readers. For more information about
the journal, go to:
https://planetary-research.org
Planetary Research is supported by the Planetary Research Cooperative.
For more information about the Planetary Research Cooperative, go to:
https://coop.planetary-research.org
We hope you will enjoy expanded access to the latest science in our
profession.

A PETITION FOR CONTINUED FUNDING OF MEASUREMENTS BY NASA'S NEW
HORIZONS MISSION
It is my (James Green, former Planetary Science Division Director)
understanding that continued New Horizons heliophysics measurements
are threatened unless NASA finds a way for the Heliophysics Division
to fund the data collection and downlink. The Heliophysics Decadal
states "New Horizons will fill a major gap in the understanding of the
plasma physics of the outer heliosphere" (Priority Science Goal 4).
New Horizons measurements are unique and must continue uninterrupted.
New Horizons is the only spacecraft now in the outer heliosphere and
is an essential element of the Heliophysics System Observatory making
measurements that the two Voyager spacecraft were not equipped to do.
For example, New Horizons is making in-situ measurements of Pick-Up
Ions source population that the Interstellar Mapping and Acceleration
Probe (IMAP) observes remotely as energetic neutral atoms. This New
Horizons-IMAP partnership provides a unique opportunity that will
probably never again arise and must be fully exploited which should
significantly help in defining future missions. Help make our
planetary missions multidisciplinary by signing the petition.
For questions, contact: James Green, jlgreen1@earthlink.net
To sign the Petition please go to:

UNIVERSITY OF HAWAII ASSISTANT/ASSOCIATE PROFESSOR
The Hawai'i Institute of Geophysics and Planetology (HIGP), University
of Hawai'i at Manoa (UH Manoa), seeks applicants for a full-time,
permanent, tenure-track faculty position at the rank of Assistant
Professor (F3M11) or Associate Professor (F4M11). We are looking for a
highly talented individual with interests in outer Solar System
science who is positioned to take advantage of existing and upcoming
high-priority missions and complements existing strengths and
expertise in HIGP. Specific focus areas can include but are not
limited to: icy ocean worlds and their habitability; giant planet and
satellite interiors, atmospheres and surface geology; and small
bodies, including trans-Neptunian objects and exoplanets; astrobiology
in outer Solar System environments; and laboratory, theoretical,
computational, or observational studies of planetary materials
relevant to these worlds. The successful candidate must pursue and
obtain extramural funding to support a vigorous research program.
The selectee may also be appointed to serve as Associate Director of
the NASA Hawai'i Space Grant Consortium (HSGC) and may assume the role
of HSGC Director after successful completion of their probationary
period.

MARS SCIENCE LABORATORY MAHLI TECHNICAL REPORT 0042: SOLS 4613-4709
MAHLI Technical Report 0042 - Sols 4613-4709, is released. These are
data that went out to the public via NASA PDS earlier and all of the
images were already deleted from the DEA. The Tech report can be found
on both Zenodo and Research Gate.
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.).

[DPS-58] FIELD TRIP AT DPS-58 MEETING
The DPS-58 Local Organizing Committee is hosting a field trip to the
Channeled Scablands Sunday, 25 October, 8:00 am - 5:00 pm for $165
/person. Spokane, WA sits on the Columbia River flood basalt that is
an analog for basaltic flows on the Moon, Mars, Mercury, and Venus.
The Channeled Scablands were formed on the lavas by megafloods from
Pleistocene glacial Lake Missoula, and are an analog to Martian
outflow channels. The cost covers lunch and bus transportation from
the conference center and back in time for the opening ceremony. Most
stops are overlooks, but some have very short walks to outcrops. You
must register for the meeting and add the trip to your registration.
Login to the registration page with the same username and password
that you used to register, scroll down, add the trip to your
itinerary, and proceed to checkout.

[DPS-58] DEPENDENT CARE APPLICATIONS
The Division for Planetary Sciences (DPS) offers Susan Niebur
Dependent Care grants to support attendance at DPS-58 to be held 25-30
October 2026 in Spokane, Washington, U.S.A. These grants provide
financial assistance to qualifying members to facilitate their meeting
attendance by offsetting costs for child care, elder care, spousal
care, etc., at the meeting location or at home during the DPS
conference. Apply for a dependent care grant here:

[DPS-58] CONFERENCE LODGING
Please consider arranging your hotel for DPS-58 at official conference
lodging. There is a block of rooms at government rates, and lodging is
connected to the conference venue-the Spokane Convention Center-via a
covered a walkway. The hotel features an onsite restaurant and other
options are located nearby. Utilizing this lodging will cut both cost
to attend the conference and carbon footprint to attend the conference
by eliminating the need for car rental.

planetary exploration. There will also be plenty of time to ask your
own questions. Panelists include Shannon MacKenzie, Samuel Howell,
Marc Neveu, Julie Castillo-Rogez, Chris Glein, and Olivier Witasse.
This panel will be held virtually on Wednesday, September 2 at 2PM
(EDT) for 90 min. Please complete this form to register:
