About

Donald R. Pettit is a NASA astronaut and chemical engineer whose research spans microgravity fluid physics, space-based materials science, and the practical challenges of long-duration spaceflight. His most cited work, "Rocks to Robots" (2010), explores the intersection of planetary geology and autonomous exploration, proposing innovative methods for using robotic systems to analyze extraterrestrial materials—a concept that has influenced mission planning for lunar and Martian surface operations. While his citation count is modest (3 for this paper), Pettit’s impact is measured in his hands-on contributions to the International Space Station (ISS), where he conducted pioneering experiments on capillary flow and fluid behavior in microgravity, directly informing spacecraft life-support and fuel-transfer systems. A veteran of three spaceflights, including a six-month stint on the ISS, Pettit is also known for his public outreach, co-authoring the popular "Saturday Morning Science" series that demystifies orbital physics. His work bridges fundamental science and applied engineering, making him a key figure in advancing humanity’s ability to live and work in space.
