Proposals may be submitted at any time through March 31, 2026 (the open period of ROSES-25), but reviews will occur a few times a year (see Table C.2-1 in Section 3.1). ROSES-2025 Amendment 6 makes several changes: It establishes that the anonymized Table of Work Effort and references are outside of the 5-page S/T/M section (see Section 3.2), removes an exclusion regarding data archiving (see Section 2.1), changes the first proposal submission cut-off date for inclusion in the Winter 2025 review to September 15, 2025, changes the second estimated review date to Spring 2026 (see Table C.2-1 in Section 3.1), and removes the HEC requirement in the S/T/M as it appears as a cover page question, see Section 3.2. New text is in bold and deleted text is struck through.

The TAPS meeting aims to strengthen interactions within the Texas planetary-exoplanet science and astrobiology community and foster collaborations & partnerships between institutions & researchers. We encourage researchers, faculty, postdocs, and students interested in planetary science and astrobiology/exoplanet research to join us for this two-day event. The meeting website has been updated: https://sites.google.com/view/tapsmeeting/home You can submit your abstract, apply for a travel grant, and register on the website. We are pleased to offer travel grants for attendees at all career stages, supported by the Heising-Simons Foundation. Here are the deadlines to keep in mind: September 1: Abstract Submission Deadline September 2: Travel Grant Application Deadline September 3: Registration Deadline Please contact Xinting Yu (xinting.yu@utsa.edu) or tapsmeeting@gmail.com for any questions. 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 GEMINI USERS POLL We would like to request your participation in a community survey being conducted in advance of a Users' Committee for Gemini (UCG) meeting to be held on September 23-24, 2025. The UCG meetings include comprehensive discussions on Gemini science priorities, current and future instrumentation, strategic planning, communication strategies, and more. This questionnaire is meant to specifically inform how Gemini communicates with its user communities in the future, so your responses are vital to guiding these discussions. To allow time to incorporate your responses and generate discussion points, responses are requested by Friday, August 15, 2025. As the representatives of the Solar System community on the UCG, we would like to particularly encourage participation from our community to help ensure our unique needs and priorities are captured by the survey. Please note that you do not have to be a regular Gemini user (or a user at all) to fill out the survey. Feedback from all is welcome! The form can be accessed at: https://forms.gle/xDi5o7AyuysTkUm18 Regards, Henry Hsieh & Charles Schambeau Users' Committee for Gemini (UCG) 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 LUNAR SURFACE SCIENCE WORKSHOP: ARTEMIS IV LANDING SITE Date: September 10, 2025 Time: 11 am ET - 5 pm ET Co-Chairs: Barbara Cohen (NASA Goddard Space Flight Center); Jennifer Heldmann (NASA Ames Research Center); Sam Lawrence (NASA Johnson Space Center). This Lunar Surface Science Workshop (LSSW) will focus on how to optimize the Artemis IV landing site to address science objectives of the mission. Key science focus areas include South Pole-Aitken Basin's unique geochronology, geochemistry, and geophysics as well as other high priority science objectives (e.g., volatiles, planetary evolution, regolith processes, Heliophysics, Biological and Physical Sciences). Abstract submission is now open! Go to: https://sservi.nasa.gov/lssw/artemis-iv-landing-site-workshop Abstracts are due August 22, 2025. Abstracts should focus on providing criteria that can be used for landing site evaluations to optimize scientific return from the Artemis IV mission, not on the identification of specific landing sites. Abstracts considering data analysis required to develop and/or assess figures of merit are also welcome. If you are interested in volunteering to facilitate breakout sessions, take notes during a discussion session for use by NASA and for generating a workshop report, and/or contributing directly to the report document, please contact barbara.a.cohen@nasa.gov and/or jennifer.heldmann@nasa.gov 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 STFC-FUNDED POSTDOCTORAL RESEARCH ASSOCIATE POSITION AT UNIVERSITY OF LEICESTER The role is to analyse data from the James Webb Space Telescope and Hubble Space Telescope of Jupiter's H3+ and FUV auroral emissions, and to develop ionospheric models. This combined dataset provides an exciting new window into the behaviour of Jupiter's auroral ionosphere. In addition to the existing data, we have further HST and JWST observations which will take place over the next observing cycle, and you will take the principal role in reducing and analysing these new data. These observations will specifically target the morphology of the Io footprint and the dusk active region of intense H3+ emission. You will investigate these novel auroral observations in conjunction with a model of auroral precipitation in order to generate novel scientific insights into giant planet auroral processes.

To provide the scientific community additional information (what these data measure; how to access; limitations, etc.), and an opportunity to ask questions about these data, the Psyche GRNS team will hold an online webinar on Thursday August 28, 2025 at 4pm EDT (1pm PDT). Information about the webinar, including a meeting link, will be posted at the following location: https://psyche.ssl.berkeley.edu/event/psyche-grns-data-webinar/ All who are interested in accessing and working with these data are encouraged to attend.

The registration deadline is September 8, 2025. In this workshop we introduce the basic principles of photogrammetry and the skills necessary to make a Digital Terrain Model from stereo image pairs. Participants will go through the process of creating a DTM and orthorectified images with a HiRISE stereo pair using BAE's SOCET SET software and 3D hardware. We will also cover the use of Ames Stereo Pipeline and Structure-from-Motion (SfM) using Agisoft Metashape. The workshop is intended for researchers at any level who want to learn to generate their own stereo products. No prior expertise is required. Two travel grants are available for attendants.
