Abstract
Planetary habitability is shaped by a combination of interior, surface, and external processes that interact to determine the long-term evolution of a planet. Understanding planetary habitability within our solar system requires comparing these processes across planets and moons with those on Earth, the only currently known habitable planet. Much of our knowledge about solar system bodies has been obtained through planetary exploration, which remains essential for advancing our understanding.
To strengthen this effort, a new Planetary Science Network in the Netherlands is being established. The network builds on the existing expertise in solar system research within the Dutch scientific community and aims to develop a framework for identifying key observables that enable the detection and assessment of planetary habitability through both in situ and remote sensing observations.
The research is organised around three main themes. The first theme focuses on planetary interiors, using Ganymede as a case study. The second theme examines surface morphology, particularly landform development, with Mars serving as the primary case study. The third theme investigates surface composition by comparing Earth's oldest geological surfaces with those of Mars and icy moons.
Through a synergistic approach within the network, these themes will produce both case-study-specific observables and more general observables that can be applied across the solar system and to the growing number of known exoplanetary systems. The network aims to strengthen the position of the Dutch planetary science community and support active contributions to the development of instruments for future planetary exploration missions. In addition, it will foster closer collaboration with the strong Dutch exoplanet research community, helping to bridge the gap between what should ideally be observed and what is currently feasible to observe.
This presentation introduces the network, its research goals, and its strategy for advancing the study of planetary habitability, while inviting collaboration and discussion within the international planetary science community.
