About

Jerry Penegor is a planetary scientist whose work has been instrumental in advancing our understanding of Mars through robotic exploration. His primary research areas include planetary surface imaging, robotic arm operations, and the geological analysis of extraterrestrial terrains. Penegor’s most notable contribution is his leadership in the Surface Stereo Imager (SSI) investigation for the Phoenix Mars Lander mission. This instrument provided critical three-dimensional imaging of the Martian arctic, enabling scientists to characterize the soil, ice, and atmospheric interactions at the landing site. The SSI data directly supported the Robotic Arm’s digging operations, which uncovered subsurface water ice and delivered samples to onboard chemistry instruments. Penegor’s work, cited 28 times in his most recognized paper, has been foundational for subsequent polar missions like InSight and Mars 2020. His achievements include helping to confirm the presence of water ice on Mars and contributing to real-time mission planning through high-resolution stereo imagery. For students and researchers, Penegor exemplifies how precise instrument design and field operations can unlock the secrets of planetary environments, bridging the gap between engineering and discovery.
