About

Walter Gerstle is a visionary aerospace engineer whose career has been defined by bold, interdisciplinary thinking about humanity’s future in space. His most recognized work, the 1990 study “Lunar Astronomical Observatories: Design Studies,” has garnered 8 citations and remains a foundational reference for researchers exploring the Moon as a premier site for 21st-century astronomy. In this landmark paper, Gerstle led a diverse team of university students and faculty from engineering, astronomy, physics, and geology, alongside industry engineers, to systematically evaluate the lunar surface as the inner solar system’s optimal location for grand observatories. This work exemplifies his core research areas: space systems design, lunar infrastructure, and the integration of scientific and engineering disciplines for ambitious space missions. Gerstle’s contribution lies not only in advancing the technical case for lunar astronomy but also in pioneering a collaborative, student-inclusive research model that has inspired a generation of engineers. His studies continue to inform NASA’s and other agencies’ long-term plans for lunar outposts, demonstrating how a single, well-crafted design study can shape the trajectory of space exploration for decades.
