The event should be open to general participation by the planetary community. Each award offers a certificate and up to $2,000 in travel support, to be presented by a PSI representative at a scientific conference or meeting. We believe these awards can foster international collaboration and broaden the horizons of aspiring planetary scientists. For more information, go to: https://www.psi.edu/pierazzo-award/ Applications close 9 PM MST, November 25, 2025 for meetings occurring in calendar 2026. Late applications will not be accepted. Award winners will be announced on or before December 7. 2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2 [EGU26] SESSION PS5.2: EARLY SOLAR SYSTEM - CRUCIAL TIMINGS FOR HABITABILITY We invite abstract submissions to the EGU 2026 session "Early Solar System - Crucial Timings for Habitability", organised by Kristina Kislyakova, Louis Muller, Anuja Raorane, Stephen Kane, and Tim Lichtenberg: https://meetingorganizer.copernicus.org/EGU26/session/56110 This session is dedicated to studies of the divergent evolution of the Earth, Venus and Mars and the role played by the Sun. We aim to provide a synergetic view of the evolution of the three planets, with contributions on planetary interiors and magnetic dynamos, and atmospheres' formation and escape being equally welcome. The abstract submission deadline is 15 January 2026. 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 POSITIONS AT THE SWEDISH INSTITUTE OF SPACE PHYSICS PhD student in space physics (dnr: 2.2.1-362/25): https://www.irf.se/en/karriar/861091/ Postdoctoral position in space physics (dnr: 2.2.1-363/25): https://www.irf.se/en/karriar/869052/ Staff Scientist, Ionospheric Physics (dnr: 2.2.1-364/25): https://www.irf.se/en/karriar/868274/ 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 UT AUSTIN CENTER FOR PLANETARY SYSTEMS HABITABILITY PRIZE POSTDOCTORAL FELLOWSHIP The Astronomy Department and the Center for Planetary Systems Habitability (CPSH) at the University of Texas at Austin invite applications for an institutional prize postdoctoral fellowship. CPSH is an interdisciplinary organization at UT Austin that seeks to advance our understanding of planetary habitability by bringing together members from three different Colleges within UT Austin (the College of Natural Sciences, Jackson School of Geosciences, and Cockrell School of Engineering): https://habitability.utexas.edu/ We are seeking candidates with knowledge and/or interest in habitability, broadly interpreted. Successful candidates will indicate two mentors associated with the Center, including one from the Department of Astronomy and another from a different department. The ideal candidate will work on a series of projects that intersect two or more disciplines. The start date is September 2026. Before starting, the applicants should have obtained a Ph.D. in Astronomy, Planetary Science, or related field. Initial appointment is for 1 year, expected to be renewed for up to 3 years. The deadline for applications is December 8, 2025. Application details can be found here: https://aas.org/jobregister/ad/7c51f40c 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 [NASA] ROSES-25 AMENDMENT 12: F.10 PRISM STEP-1 DUE DATE TBD The Step-1 proposal due date for F.10 PRISM is changed to TBD as a result of the continuing government shutdown. The solicitation "close date" shown in NSPIRES is NOT a new proposal due date; that is merely an artefact of the NSPIRES system. When funding is reinstated, amendments will be issued setting new due dates. We anticipate that proposers to programs that were set to TBD will be given back as many business days as the government was shut down. Questions concerning F.10 PRISM may be directed to Ryan Watkins at HQ-PRISM@mail.nasa.gov but the civil servant points of contact for this program will not be permitted to reply until the government reopens.

These pristine grains reveal evidence of diverse, aqueous, chemistry and could form part of larger chemical cycles beneath the icy crust, enhancing the likelihood that the small moon is habitable, and driving the need for future missions.
