Open Researchers 2022-23 is the 11th Andalusian experience in the European Researchers' Night. The project is designed to increase the awareness and perception of research as a solution to the numerous challenges faced by citizens all around the world, as well as showing Science as the way to achieve the goals of the Horizon Europe Missions. ‘Excellence Science for boost a greener, smarter and healthier future in Europe with and for citizenship’ is the main idea of the project. It has been conceived at a time when the UE has just launched Horizon Europe in order to join efforts to face the greatest societal challenges that Europe is facing. Understanding that science is present in our daily lives, it should be accompanied by a scientific culture that will prepare citizens to a reality full of challenges. It is essential to promote youth interest in Science by opening it to the general public through researchers in an accessible way. Fundacion Descubre will coordinate this project, based on its experience through the last decade working with relevant projects and in its consortium experience in the previous NIGHT projects. The consortium is composed of 9 Andalusian universities, the Spanish National Research Council (CSIC), Andalusian Foundation Progress and Health, and the Royal Botanical Garden of Cordoba. The project's major strength is the numerous activities taking place on streets, theatres, and historical buildings of the 8 Andalusian cities, with a high mobilization of researchers and collaborating institutions. To reinforce this, partners will consolidate a strong programme of activities at schools. The European dimension will be underlined by the active involvement of researchers funded by EU and MSCA fellows in the event. Gender balance will be guaranteed in researchers as well as the RRI for designing inclusive and sustainable R&I. The project includes a European collaboration to design a set of shared activities linked to Horizon Europe Missions.
