About

Jason Hartwig is a researcher specializing in cryogenic fluid management systems for space exploration applications, with a particular focus on enabling in-space propulsion technologies critical to NASA's Moon and Mars mission architectures. His work addresses one of the most technically demanding challenges in aerospace engineering: the behavior of cryogenic propellants in microgravity environments, where conventional fluid dynamics assumptions break down entirely. Hartwig's most influential contribution, "Nitrogen flow boiling and chilldown experiments in microgravity using pulse flow and low-thermally conductive coatings" (2022, 24 citations), demonstrated innovative strategies for managing cryogenic fluid systems upstream of propellant feed lines — a prerequisite for reliable in-space engine ignition and cryogenic fuel depot operations. His complementary investigations into spray quenching, no-vent fill (NVF), and charge-hold-vent (CHV) techniques further establish him as a leading authority on tank-to-tank cryogen transfer in microgravity, accumulated across nearly 50 total citations. Hartwig's research directly supports NASA's broader Artemis program goals, providing the foundational experimental data and predictive frameworks necessary to make long-duration cryogenic propellant storage and transfer a practical reality for future deep space human exploration missions.
