About

Tracie Prater is a researcher whose work spans advanced manufacturing processes and space exploration technology, with particular expertise in friction stir welding (FSW) and additive manufacturing for aerospace applications. Her 2013 paper on friction stir welding—a comprehensive examination of process mechanics, automation, and control—has become a landmark reference in the field, accumulating over 500 citations and establishing her as a leading voice in manufacturing research. Earlier work on in-process gap detection in robotic FSW demonstrated her commitment to practical, real-world implementation of intelligent manufacturing systems. Prater has since channeled this manufacturing expertise into NASA's human spaceflight program, contributing to initiatives in additive manufacturing for deep space exploration and leading efforts around NASA's Centennial Challenge for 3D-Printed Habitat—a public competition designed to accelerate construction technologies for off-Earth habitation. Her more recent work on exploration capability gap analysis reflects a broadened scope, helping NASA prioritize technology development for future crewed missions beyond low Earth orbit. Across her career, Prater exemplifies the researcher-engineer archetype—bridging fundamental manufacturing science with the demanding, high-stakes requirements of human space exploration.
