About

P.J. McNally’s research bridges the frontiers of planetary science and spacecraft dynamics, with a focus on in-situ geochemical analysis and autonomous control of complex space systems. His most impactful contribution is the development of PIXL (Planetary Instrument for X-Ray Lithochemistry), a micro-focus X-ray fluorescence spectrometer that has revolutionized Mars exploration. Deployed on NASA’s Perseverance rover, PIXL precisely maps elemental chemistry at microscopic scales, enabling scientists to identify biosignatures and understand the geological history of Jezero Crater. This instrument, detailed in a 2020 paper with 135 citations, represents a landmark achievement in planetary instrumentation, directly supporting the search for ancient life on Mars. Earlier in his career, McNally tackled the challenging problem of attitude control for underactuated multibody spacecraft—systems with fewer actuators than degrees of freedom. His 1996 paper on this topic, while less cited, laid foundational work for controlling flexible or damaged spacecraft, influencing subsequent research in autonomous space operations. McNally’s work exemplifies how cutting-edge instrument design and theoretical control engineering converge to advance space exploration, making him a key figure in both planetary science and aerospace engineering.
