"This Townhall Meeting aims to give an outlook of new directions in scientific research that could be possible if online data sets, tools, and research infrastructures are fully integrated on a global scale across scientific disciplines as well as sectoral and national boundaries.

Looking up to the sky: Flying around in the Open Science Universe, we identify what is already there – what can we reach with our scientific starships and how can we benefit? What spectacular scientific results can we foresee with Open Science approaches? What would be needed to achieve them?

Looking back down to earth: We identify the current barriers or challenges and brainstorm ways to overcome them. What does this require from all of us and our current way of thinking about integrating data and science? How can we boldly go where no scientist has gone before?

After lightyears of preparation and exploration together with previous Town Halls at EGU General Assemblies in 2019 and 2023, the Open Science Starship is firmly at warp speed, aiming to promote open science across the scientific universe. It's time now to connect to Earthlings in all planetary outskirts. How can your science, your data, your publications be open to the world, your solar system and the rest of the scientific universe.
How can we join the forces of the Research Jedi, convert the Borg to FAIR, liaise with the Klingons of 'Nature' and 'Science' and put Earth and Environmental research to the stage where it belongs: Everywhere. 'Things are only impossible until they're not'...

This Townhall Meeting follows up on sessions ESSI 3.5, 2.1, 2.8 and ITS 3.11 where various approaches demonstrate successful integration on the level of datasets and/or research infrastructures in support of scientific research, aiming to achieve true open science. Within disciplines, across disciplines, and across national or even continental boundaries. A small step becoming a giant leap."
