Dennis Miller embodies purpose, precision, and passion, on Earth and in analog space. As Chief of Operations and Flight Director for the APUS Analog Research Group, Dennis has led student teams through Mars-style simulations, drawing on two decades in the U.S. Marine Corps and his current work supporting NASA procurement at Goddard. In this episode, Dennis traces his unlikely path from F-18 avionics and hospital respirator repair to multimillion-dollar reconstruction programs in Iraq, and eventually to mission planning for high-fidelity analogs. We unpack his “intent over instructions” approach, how to build schedules with buffers, and what real risk management looks like when suit docking fails and emotions run high. Plus: favorite experiments (spirulina, mobility rigs, rescue sleds), how ILMAH and SAM differ, and why future mission controllers should experience analogs firsthand.
