Advances in Extraterrestrial Drilling:

Advances in Extraterrestrial Drilling: Ground, Ice, and Underwater includes the latest advances that have been made in recent years in developing drilling and excavation mechanisms for extraterrestrial bodies. The chapters cover drill types, drilling techniques and their advantages and associated issues, rock coring including acquisition, damage control, caching and transport, and data interpretation, as well as unconsolidated soil drilling and borehole stability. This book includes a description of the basic science of the drilling process, associated processes of breaking and penetrating various media, the required hardware, and the process of excavation and analysis of the sampled media. - Covers the most recent advances in extraterrestrial drilling. - Discusses drilling in the broadest range of media including ground, ice, underwater, and planetary surfaces from shallow to very deep. - Provides a comprehensive description of key drilling techniques and the efforts to develop unified approach to assessing the required tools for given drilling requirements. - Discusses how environment affects drilling and approaches to addressing the effects and current challenges of drilling and excavation on other planets. - Examines novel drilling and excavation approaches. Dr. Yoseph Bar-Cohen is the Supervisor of the Electroactive Technologies Group (http://ndeaa.jpl.nasa.gov/) and a Senior Research Scientist at the Jet Propulsion Lab/Caltech, Pasadena, CA. His research is focused on electro-mechanics including planetary sample handling mechanisms, novel actuators that are driven by materials such as piezoelectric and EAP (also known as artificial muscles), and biomimetics. Dr. Kris Zacny is a Senior Scientist and Vice President of Exploration Systems at Honeybee Robotics, Altadena, CA. His expertise includes space mining, sample handling, soil and rock mechanics, extraterrestrial drilling, and In Situ Resource Utilization (ISRU).

Dr. Yoseph Bar-Cohen is the Supervisor of the Electroactive Technologies Group (http://ndeaa.jpl.nasa.gov/) and a Senior Research Scientist at the Jet Propulsion Lab/Caltech, Pasadena, CA. In 1979, he received his Ph.D. in Physics from the Hebrew University, Jerusalem, Israel. His research is focused on electro-mechanics including planetary sample handling mechanisms, novel actuators that are driven by such materials as piezoelectric and EAP (also known as artificial muscles) and biomimetics. Dr. Kris Zacny is a Senior Research Scientist, Vice President and Director of Exploration Technology Group at Honeybee Robotics. His expertise includes terrestrial and extraterrestrial robotic drilling, excavation, sample handling and processing, geotechnical systems, and sensors. Dr. Zacny received his PhD (UC Berkeley, 2005) in Geotechnical Engineering with an emphasis on Mars drilling, ME (UC Berkeley, 2001) in Petroleum Engineering with emphasis on Drilling and Materials Science, and BSc cum laude (U. Cape Town, 1997) in Mechanical Engineering.
