Science drivers are the underlying motivations and goals that guide scientific research in a particular field. They are the key questions, challenges, or opportunities that researchers seek to address with their work. Science drivers help to prioritize research efforts, funding allocation, and resource allocation in order to address the most pressing issues or achieve the most impactful outcomes. In various research areas, science drivers can range from fundamental questions about the nature of the universe, to practical applications that could improve human health, technology, or society. For example, in the field of astronomy, science drivers may include understanding the origins and evolution of galaxies, discovering exoplanets, or unraveling the mysteries of dark matter and dark energy. Overall, science drivers play a crucial role in shaping the direction of research and advancing knowledge in a particular field. By identifying and prioritizing these key questions and challenges, researchers can make significant progress towards answering them and making important contributions to their field.
