About

Jacob Chesin is a pioneering aerospace engineer whose work focuses on advancing autonomous drilling and sampling technologies for planetary exploration. His major contributions center on the development of intelligent, low-mass drilling systems capable of penetrating deep into the subsurface of celestial bodies—a critical capability for future NASA missions seeking to uncover signs of past life or geological history. Chesin’s most cited paper, “Auto-Gopher-II: an autonomous wireline rotary-hammer ultrasonic drill” (2017, 12 citations), showcases his leadership in creating a self-contained, energy-efficient drill that combines rotary, hammering, and ultrasonic actions to operate in harsh extraterrestrial environments. This innovation addresses the dual challenge of minimizing spacecraft mass and power consumption while maximizing drilling depth and sample integrity. Chesin’s work has direct implications for missions to the Moon, Mars, and icy moons like Europa, where subsurface access is key. By integrating autonomy and robust mechanical design, he has helped lay the groundwork for next-generation planetary science, earning recognition within NASA’s technology development programs. His research continues to inspire students and engineers aiming to push the boundaries of in-situ resource utilization and astrobiology.
