About

Christopher H. McLean is a leading aerospace engineer whose work centers on in-space propulsion, cryogenic fluid management, and the development of practical orbital infrastructure. His most influential contribution is the concept of a simple, robust cryogenic propellant depot for near-term space applications, which has garnered 35 citations and reshaped thinking about on-orbit refueling. This work challenges the traditional paradigm of single-launch missions by demonstrating how cryogenic depots can enable sustainable, reusable space transportation for NASA’s Exploration program, deep-space robotic missions, national security payloads, and commercial ventures. McLean’s research addresses one of the most critical bottlenecks in spaceflight: the ability to store and transfer cryogenic propellants in microgravity. His innovative depot design emphasizes reliability and simplicity, making it a viable near-term solution rather than a distant concept. By advancing the technology needed for orbital refueling, McLean has laid the groundwork for more ambitious missions beyond low Earth orbit, including lunar and Martian exploration. His work stands as a foundational reference for engineers and mission planners seeking to reduce launch costs and extend the reach of human and robotic spaceflight.
