Dear MSA-Talk subscribers, The Center for Planetary Origins to Habitability (CPO2H) ( https://www.origins2habitability.rice.edu/) of Rice Space Institute at Rice University is organizing an international *Inner Solar System Workshop: From Formation to Coupled Interior–Surface Evolution*. The workshop will take place at Rice University on May 12–14, 2026. The workshop will bring together researchers working on planetary formation and dynamical evolution, using cosmochemistry tools and astromaterials, and the coupled evolution of planetary interiors, surfaces, and atmospheres, with a particular focus on rocky bodies in the inner Solar System. The planned thematic areas for the workshop are as follows: • *Accretion of Terrestrial Planets, Solar System Formation, and Evolution* Physical and dynamical processes governing the growth and evolution of planets in the Solar System. • *Geochemistry and Cosmochemistry of Astromaterials and Volatile Delivery* Constraints from meteorites, isotopes, and laboratory analyses on planetary compositions and volatile acquisition. • *Planetary Differentiation and Interior–Surface Exchanges Through Time* Properties of planetary interiors and coupled chemical and physical evolution linking planetary interiors, surfaces, and atmospheres through time from a variety of approaches. The workshop will feature *invited speakers, contributed talks, and poster sessions* across all three themes. If you are interested in participating, please fill out the expression of interest form available at the link below. Also, bring the workshop to the attention of your mentees or collaborators, whom we may have missed reaching out to. https://www.origins2habitability.rice.edu/expressioninterest To ensure a lively discussion among all participants, we plan to limit this workshop to 70-80 participants. We kindly ask that you complete the ‘expression of interest’ form at your earliest convenience, ideally by *Tuesday, February 15, 2026.* Submitting an expression of interest will help us plan and schedule the workshop. We expect to have the workshop attendee list finalized by early March. Please note that we may not be able to accommodate all requests from potential participants. We would also like the participants to attend all three days of the workshop. There is no registration fee to participate. We will provide all meals during the meeting, including one workshop dinner. Limited travel funds are also available to partly offset the cost of travel and lodging for the participants. More information about the workshop is available on the workshop webpage: https://www.origins2habitability.rice.edu/workshop Please do not hesitate to contact us if you have any questions.
