Our speakers Therese Encrenaz (Paris Observatory) and Rakesh Mogul (California State Polytechnic University) recently published brand new results that feed new information into this study. Therese Encrenaz has been observing Venus for decades from Earth and she will provide with an overview of her findings. Rakesh Mogul re-analysed Pioneer Venus descent probe data and discovered new information about the chemical composition of the sulpheric acid cloud particles. Join us in this 75 minutes long get-together listening to these new findings, and participating in the open informal discussion that will follow to share your thoughts on this enigmatic topic. This webinar will be in normal-Zoom-mode, with all attendees being able to have video and audio if they wish. Both speakers will present for 25 minutes. After that we have 25 minutes time for discussion about the topic among all the participants. Please bring your ideas and thoughts on the topic and let's engage in an interactive and constructive scientific discussion!

If so, you probably realized that there are few good solutions for our community. The Planetary Research Blog aims to fill this void. This website will publish announcements, commentaries, research summaries, and blog posts that are of interest to the broad planetary science community. Posts may have co-authors and may include images and videos. All content is free to access, without ads or intrusive trackers. If you would like to be an author on our site, it is only necessary to first become a member of the Planetary Research Cooperative: https://coop.planetary-research.org Membership is free after accepting the association's code of conduct. For more information, please check out our inaugural blog post: https://tinyurl.com/36u7e4tb 6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6 [NASA] PDS: RMS NODE USERS GROUP DURING DPS MEETING We plan to convene the RMS Node Users Group on Wednesday, December 3, at 10am Pacific / 1pm Eastern. This meeting will be via Zoom. The meeting will take up to two hours. The PDS Ring-Moon Systems Node (RMS) hosts data and tools in which the focus is on rings, moons, and/or their primary bodies viewed as a dynamical system. Our user community includes researchers interested in icy satellite surfaces and planetary atmospheres, in addition to researchers interested in rings and other dynamical systems. This meeting is an opportunity for friends of the PDS Ring-Moon Systems Node to hear us report on RMS Node updates and accomplishments during the past year, and for us to solicit your feedback regarding how we should proceed. For remote attendees, the Zoom coordinates and agenda will be sent by email. To be added to our list, please contact Megan Seritan (mseritan@seti.org). 7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7 [NASA] ROSES-25 AMENDMENT 14: F.9 CITIZEN SCIENCE SEED FUNDING PROGRAM PROPOSAL DUE DATE RESET TO JANUARY 22, 2026 F.9 The Citizen Science Seed Funding Program (CSSFP) aims to incubate citizen science projects as they are being conceived or during critical transitions, like the year when they are first launched or beta tested or when the project changes scientific direction. CSSFP awards have a duration of up to one year only. NASA expects that funded citizen science efforts will lead to scientific results published in peer-review publications. Projects that include students are welcome, as long as the main goals of the proposed investigation are science results and not educational impacts. The CSSFP does not solicit efforts whose sole aim is to create tools for citizen science or efforts for which the primary purpose is outreach or education, engineering or software development. ROSES-2025 Amendment 14 resets the proposal due date for this program element, which was previously set to TBD because of the lapse in government funding. The new proposal due date is January 22, 2026. Go to: https://solicitation.nasaprs.com/ROSES2025 Questions concerning F.9 CSSFP may be directed to Marc Kuchner at marc.kuchner@nasa.gov.

Proposed projects may entirely focus on addressing specific scientific questions and/or address pressing needs in the planetary science community. The burden is on the proposer to convince the panel the proposed work is timely. ROSES-2025 Amendment 15 defers the proposal due date for C.5 Planetary Science Early Career Award. The new proposal due date is January 12, 2026.

The intent of this program element is to create both high quality and internally consistent geologic maps, to determine methods for quickly and efficiently completing team-based geologic mapping, and conveying those results to the broadest range of users possible. The new proposal due date is December 15, 2025. Go to: https://solicitation.nasaprs.com/ROSES2025 Questions concerning C.10 LMAP may be directed to Sarah Noble and Amanda Nahm at HQ-LMAP@mail.nasa.gov 10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10 [NASA] OUTER PLANETS ASSESSMENT GROUP MEETING AGENDA UPDATE: NOVEMBER 18-19, 2025 Dear OPAG Community, Unfortunately, even though there is movement regarding the government reopening, we still don't have clarity on whether our HQ colleagues can attend, much less present, at our OPAG meeting next week. So, we have decided to switch to our backup agenda, which is science-focused. We will cancel the Monday portion of the OPAG meeting and hope you'll still join us Tuesday, November 18, starting at 8:45am PST / 11:45am EST for the rest of the meeting. This is just a friendly reminder to register so you can receive the link to connect virtually. Go to: https://www.hou.usra.edu/meeting_portal/registration/?mtg=opagnov2025 Looking forward to some mission updates, workshop summaries and exciting science presentations, and discussion of the path ahead. Let's make the best use of this time together! We plan to reschedule the missing agenda items as soon as availability and timing permit. Best always, Morgan and Carol, on behalf of the OPAG Steering Committee 11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11 PLANETARY MEETING CALENDAR ADDITIONS Note: Many face-to-face meetings going forward will have online components.
