rock strength and RAT grind energy for rocks with compressive strengths less than about 150MPa, a category that includes all but the strongest intact rocks. Applying this correlation to rocks abraded by Spirit's RAT, the results indicate a large divide in strength between more competent basaltic rocks encountered in the plains of Gusev crater

Basalt fiber are similar to glass fibers regarding with specific weight of 2,6g/m 3, however are characterized by 20% higher mechanical properties such as tensile and compressive strength, rigidity, EModulus and excellent resistance to chemical environment. Basalt fibers provide 10% higher absorption of electromagnetic radiation and absorption of forces.
