About

Carolyn R. Mercer is a leading aerospace engineer whose work has been instrumental in shaping NASA’s vision for deep-space exploration. Her primary research focuses on advanced in-space propulsion systems, particularly solar electric propulsion (SEP), and the development of technologies for exploring ocean worlds like Europa and Enceladus. Mercer’s major contributions include pioneering designs for multi-kilowatt electric propulsion systems capable of transporting large cargo to Mars, as detailed in her highly cited 2011 paper (12 citations). She also advanced the concept of using high-power SEP for human space exploration, demonstrating how these systems could enable cost-effective missions throughout the solar system (11 citations). More recently, her work has shifted toward the challenging task of developing science and technology for exploring subsurface oceans on icy moons, a key priority in the search for extraterrestrial life (4 citations). As a key figure at NASA, Mercer’s research bridges the gap between current propulsion capabilities and the ambitious goals of human Mars missions and outer planet exploration, making her a vital contributor to the future of spaceflight.
