About

C. L. Marion is a leading figure in planetary analogue mission research, specializing in the operational architectures and robotic systems required for future sample return from the Moon and Mars. Marion’s work centers on the critical challenge of integrating geological field science with remote robotic control, a theme that runs through their most influential publications. Their major contribution is the development and field-testing of mission control frameworks that enhance geologically-focused situational awareness for remote operators. This is exemplified by their leadership of the CanMars Mars Sample Return analogue mission, which remains their most cited work with 33 citations. Marion’s research, including studies at the Sudbury and Mistastin Lake impact structures, has demonstrated how robotic systems can effectively conduct high-fidelity geological exploration. A particularly notable achievement is their work on a Network of Reusable Paths (NRP), a novel navigation architecture that allows a rover to precisely retrace its steps. This innovation enables parallel exploration of multiple scientific targets, representing a significant advance in planetary surface exploration strategy. Through a series of integrated robotic and human analogue missions, Marion has provided foundational insights that directly inform the design of future planetary exploration campaigns.
