Several recent and planned space projects have been focussed on surface rovers for planetary missions, such as the U.S. Mars Exploration Rovers and the European ExoMars. The main functions of similar extraterrestrial vehicles in the future will be moving across planetary surfaces and retrieving rock samples. This paper presents a novel ultrasonic rock sampling tool tuned in a longitudinal-torsional mode along with the conceptual design of a full coring apparatus for preload delivery and core removal. Drilling and coring bits have been designed so that a portion of the longitudinal motion supplied by the ultrasonic transducer is converted into torsional motion. Results of drilling/coring trials are also presented.
