  • Who We Are

    The Outer Space Institute (OSI) is network of world-leading space experts united by their commitment to highly innovative, transdisciplinary research that addresses grand challenges facing the continued use and exploration of space. Comprised of physical scientists, social scientists, lawyers, engineers, industry leaders, and policy makers, there is no other body like it anywhere. The transdisciplinary approach enables the OSI to identify challenges, opportunities, and solutions that have been overlooked by other groups. By breaking down barriers that prevent people in different fields from working together, the OSI is able to further challenge assumptions that are often taken for granted in building public policy.
