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.

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: https://c.org/Yv6zG7JnvL 3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3 MS/PHD POSITIONS FOR FALL 2027 I am community sourcing a list of people who are actively in search of MS/PhD students in planetary science/astrobiology/exoplanets for Fall 2027. If you are such a person, please fill out the following google form: https://tinyurl.com/33fbfked Prospective graduate students, please find the resulting list at: https://tinyurl.com/4vn4mpsn Questions- Please email Sarah Horst (Sarah.horst@jhu.edu) 4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4 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. https://tinyurl.com/ytv945nk 5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5 PLANETARY GEOMORPHOLOGY IMAGE OF THE MONTH The August image of the month is now available at the IAG's Planetary Geomorphology web page: https://planetarygeomorphology.wordpress.com This month's topic is 'Revisiting the Enigma of Pluto's Most Enigmatic Terrain: The Bladed Deposits of Tartarus Dorsa', contributed by Victor Belissa, PhD student from Nantes University, France.

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.). Citation: R. A.

DPS-58 will be a hybrid meeting with live-streamed in-person and recorded virtual talks and in-person posters. Three classes of registration include: full in-person, full virtual, and virtual meeting observer for low cost. Regular registration deadline: 20 August 2026 Late registration begins: 21 August 2026 10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10 [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. 11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11 [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: https://dps.aas.org/development/dps-dependent-care-grant-application/ 12-12-12-12-12-12-12-12-12-12-12-12-12-12-12-12-12-12-12-12-12-12-12-12 [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. 13-13-13-13-13-13-13-13-13-13-13-13-13-13-13-13-13-13-13-13-13-13-13-13 [DPS-58] INFORMATION FOR EXHIBITORS AND SPONSORS The Local Organizing Committee for DPS-58 is soliciting exhibitors and sponsors for the meeting.
