About
William A. Hartman is a leading aerospace engineer specializing in spacecraft environmental monitoring and leak detection technologies for human spaceflight. His primary research focuses on the characterization of the natural and induced environment around the International Space Station (ISS) and the development of robotic systems to safeguard crewed spacecraft from hazardous fluid and gas leaks. Hartman’s most significant contribution is his central role in the conception, deployment, and on-orbit validation of the Robotic External Leak Locator (RELL). This innovative instrument, mounted on the ISS’s Dextre robotic arm, demonstrated the first-ever capability to detect and localize minute external leaks—such as those from the station’s ammonia cooling loops—from a remote, robotic platform. His work, published in 2018, details the RELL’s operational successes and its characterization of the ISS’s complex background environment, which is critical for distinguishing genuine leaks from ambient contamination. While his citation counts (totaling 15) reflect the niche, highly applied nature of his field, Hartman’s impact is profound: the RELL technology he helped pioneer has become an operational asset on the ISS, directly enhancing crew safety and mission assurance for both current and future spacecraft, including NASA’s Gateway lunar outpost.
