A paradigm shift in space activity, capabilities and infrastructure has occurred in the past decade. Princeton Engineering and the University beyond have strengths in core engineering domains needed to revolutionize space architectures, technology and science, while taking into consideration broader questions of space governance and policy. This cluster of excellence is bringing together faculty from engineering and Princeton more broadly to understand where our impacts can be most successful in the space domain, to form internal networks of collaborators to initiate multi-disciplinary work in the identified areas, and to chart a vision towards external networks that enable institutional partnerships and long-term funding.
