About

Jean-Luc Josset is a leading figure in planetary exploration, specializing in the development of high-resolution imaging systems for Mars missions. His primary research focuses on the design, optimization, and scientific application of close-up imagers for in-situ geological analysis on extraterrestrial surfaces. Josset’s most significant contribution is his central role in creating the CLUPI (Close-UP Imager) instrument, a sophisticated camera system selected for the ESA/Roscosmos ExoMars Rosalind Franklin rover. This instrument is engineered to capture microscopic-scale images of Martian rock textures and sedimentary structures, a capability critical for identifying signs of past life. His foundational work on the Beagle 2 stereo camera system (23 citations) established his expertise in planetary imaging, while his subsequent research on CLUPI’s development (2 citations) and optimal operational conditions (4 citations) has been instrumental in preparing the instrument for its mission. By enabling high-resolution visual analysis of the Martian subsurface, Josset’s work directly supports ExoMars’s primary goal of searching for biosignatures, positioning him as a key architect of one of the most anticipated astrobiology investigations on the Red Planet.
