Caltech formally dedicated the Lynn Booth and Kent Kresa Department of Aerospace on April 8, marking the culmination of a $50 million endowment from Trustee Lynn Booth and Life Member Kent Kresa that permanently names and supports one of the Institute’s flagship programs. The gift, announced in December 2025, is intended to sustain Caltech’s leadership in aerospace research while expanding its reach into emerging fields such as autonomous systems, hypersonics, and space technology.

At the dedication ceremony outside the Guggenheim Aeronautical Laboratory, faculty, students, and community members gathered to celebrate what President Thomas F. Rosenbaum described as a “signature achievement” for the Institute. Speakers emphasized both the department’s legacy — spanning foundational contributions to aerodynamics, the creation of NASA’s Jet Propulsion Laboratory, and advances in robotics — and its future role amid what Kresa called a “new era of explosive growth” in aerospace.

The Booth-Kresa endowment provides broad institutional support, funding new research initiatives, modernizing experimental facilities, and strengthening recruitment and retention of faculty and students. It also establishes fellowship programs for graduate students and postdoctoral scholars, as well as flexible “bridge” funding for high-risk, interdisciplinary projects.

Department leadership has already pointed to new directions enabled by the gift, including work in fluid dynamics, hypervelocity experimentation, and advanced materials. In parallel, ongoing efforts in bioinspired robotics, autonomous systems, and space infrastructure reflect a broader shift toward integrated, cross-disciplinary aerospace research.

For Booth and Kresa, whose longstanding involvement with Caltech shaped the donation, the gift reflects a belief in supporting exploratory, high-impact science. “This is more than a gift — it’s an investment in tomorrow,” Provost David Tirrell noted, framing the endowment as both a continuation of Caltech’s aerospace legacy and a catalyst for its next phase.

The dedication concluded with a ribbon-cutting ceremony and remarks from JPL Director David Gallagher, underlining the enduring partnership between Caltech and the nation’s space program — now further bolstered by one of the largest gifts in the department’s history.
