[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:

[COSPAR] SESSION B4.3: VENUS SCIENCE AND EXPLORATION

We encourage you to submit a contribution to Session B4.3: Venus
Science and Exploration at the 46th COSPAR Scientific Assembly, to be
held in Florence, Italy, 1-9 August 2026. 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.

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.

[GOLDSCHMIDT] SESSION 01B: EXOPLANET GEOCHEMISTRY AND CLIMATE

Abstract deadline: February 26 at 11:59 Eastern

We invite all abstracts aimed at understanding exoplanets. 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.
