Knowledge creation is a collaborative process including synergies between different disciplines, communities and stakeholders. The framework of open science is also connected to the involvement of people outside academia, such as amateur societies, school students, corporate partners etc. Open science has a variety of aspects and applications. What are the efforts done in the field of planetary sciences to establish and increase openness? To what degree planetary science researchers and practitioners endeavour accessibility within the various communities - academics and non-academics? During this session these and other relevant questions will be addressed through the presentation of open planetary science projects, tools, data and platforms. Furthermore, the current status and the potential for future efforts towards an open and public planetary science scheme will be discussed. Building upon the success of the session in the previous years, planetary scientists, researchers and other stakeholders are welcome to present new projects and the developments of previous ones, in the context of promoting open & public science.
