About

Keith Warfield is a distinguished aerospace engineer whose work has centered on parametric cost modeling for deep space robotic science missions, particularly through his contributions at NASA’s Jet Propulsion Laboratory (JPL). His most cited paper, “Parametric Cost Modeling of Space Missions Using the Develop New Projects (DNP) Implementation Process” (1999), with 5 citations, introduced a groundbreaking parametric cost model that transformed how JPL estimates the costs of future, complex space endeavors. This work was developed in response to a major internal re-engineering effort at JPL, known as Develop New Products (DNP), which aimed to streamline project development and cost estimation. Warfield’s model provided a systematic, data-driven approach to predicting mission expenses, enabling more accurate budgeting and resource allocation for high-stakes interplanetary exploration. His research has had a lasting impact on space mission planning, helping to reduce financial risks and improve the feasibility of ambitious projects. Beyond this seminal paper, Warfield’s expertise in cost engineering and systems analysis has made him a key figure in advancing JPL’s capabilities, ensuring that future missions to Mars, asteroids, and beyond are both scientifically ambitious and economically viable.
