If you would like to participate, please register here: https://meta.wikimedia.org/wiki/Planetary_Science_Wiki_Edit-a-thon_2026 Please feel free to share this invitation with colleagues, students, and anyone interested - all experience levels are welcome. Let's make planetary science more inclusive, one article at a time! Best regards, Arianna Piccialli (BIRA-IASB) 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 [COSPAR] SESSION B4.1: COMPARATIVE PLANETOLOGY OF THE INNER SOLAR SYSTEM We are pleased to announce a new comparative planetology session for the 2026 COSPAR Scientific Assembly in Florence, Italy, 1-9 August 2026. We can only truly comprehend the fundamental processes and properties of Solar System planetary bodies by studying the similarities and differences between them. Comparative analyses of planetary interiors, surfaces, atmospheres, and magnetospheres through remote sensing, sample analysis, laboratory and computer modelling, fieldwork, etc. are required to place our current understanding of individual worlds, including Earth, into a common framework. This session solicits presentations of comparative planetary analyses involving two or more bodies of the inner Solar System and consequences for exoplanet research. Abstracts are due by Friday, 20 February 2026. To learn more about the session, and to submit an abstract, visit: https://www.cospar-assembly.org/admin/session_cospar.php?session=1415 We look forward to seeing you there!

The abstract submission deadline is now 20 February 2026, 23:59 CET. This session seeks presentations on all aspects of Venus, including its interior, surface, and atmosphere, focusing on recent findings and upcoming Venus missions. We welcome theoretical studies, laboratory experiments, numerical model calculations, revisiting past data, and new ground/space-based measurements. We encourage studies on terrestrial analogues to Venus, field campaigns to better understand the performance of the instruments on-board future missions, or sample collections to be tested in lab under Venus-like conditions. We also seek presentations on Venus as an exoplanet analogue, including comparisons of models validated and constrained using Venus spectral data from orbiters and in situ, to better understand observable planets under similar insolation level, and their habitability potential. The goal of the session is to promote international discussions on current and future Venus exploration.

Abstract Submission: https://www.cospar-assembly.org/user/mypapers.php?log=1 Information on abstract submission: https://tinyurl.com/mvvywrjt Early registration deadline: 17 May 2026 Visit the PPP web site: https://tinyurl.com/yxp9488h Over the next years and decades, the flavor of Mars exploration will change from a purely scientific robotic exploration to a mix of robotic and crewed scientific exploration and utilization. This would likely entail a larger number of orbital assets, including constellation-type missions for science, communication and navigation, and the landing of larger surface assets, including application of In-situ Resource Utilization (ISRU), deeper drilling, and more extended use of perennial heat sources. Whilst the objectives of forward and backward planetary protection remains the same - robotic and crew, single missions and constellations - the practical implementation of the basic planetary protection principles will have to take these changes into account for the upcoming missions going to Mars and for missions that return to Earth. This session will focus on the underlying scientific knowledge and practical implementation of the planetary protection principles considering the expected change in exploring the red planet. The session will conclude with a round-table discussion.

We strongly encourage submissions from early-career researchers and underrepresented groups. This session offers a unified forum at Goldschmidt for research that spans the chemistry and climate of planets within and beyond our Solar System. We invite contributions that integrate experiments, models, and observations to explore the condensation and differentiation of planetary materials, volatile partitioning and isotopic evolution, interior-atmosphere coupling, planetary climates and habitability, and the influence of stellar and galactic environments on planet formation. By bringing together approaches from atmospheric science, geochemistry, cosmochemistry, planetary science, and astronomy, the session aims to build dialogue between disciplines and prepare the community for the next generation of exoplanet data. It serves as a one-stop venue for researchers investigating planets as coupled chemical and physical systems, from their origins in disks to the long-term evolution of their atmospheres and interiors. We especially welcome interdisciplinary collaborations and early-career participation in this session that broadens Goldschmidt's geochemical tradition to include planetary systems across the galaxy.
