Jun 27, 2010 Qualitatively, the strength of vesicular basalt is inversely proportional to the amount of pore space within the rock as the macroporosity increases, the UCS decreases. Finding a reliable method to quantitatively estimate the strength of vesicular basalt without extensive laboratory testing would be of great benefit to the engineering community.

Each Mars Exploration Rover carries a Rock Abrasion Tool (RAT) whose intended use was to abrade the outer surfaces of rocks to expose more pristine material. Motor currents drawn by the RAT motors are related to the strength and hardness of rock surfaces undergoing abrasion, and these data can be used to infer more about a target rocks physical properties.
