摘要

A study was made to evaluate the practicality of employing the penetrometer technique as a means for determining physical characteristics of a remote sur face such as that of the moon or a planet. The study included a review of the history and fundamentals of the penetrometer concept and an examination of the basic requirements for penetrometers and necessary support apparatus.nResults of the study indicate that practical penetrometer systems can be employed to determine such surface properties as hardness or penetrability and, possibly, bearing strength. Design considerations are given for a penetrometer system which requires further development and also for penetrometer systems presently attainable but which introduce some complexity and which may impose some limitations on the attainment of experimental goals. Design considerations of support apparatus required for some missions are also presented.
