Realtime sensing while drilling using the USDC and integrated sensors

The search for existing or past life in the Universe is one of the most important objectives of NASA’s mission. In support of this objective, an ultrasonic based mechanism is being developed to allow probing and sampling of rocks and soil. The novel lightweight Ultrasonic/Sonic Driller/Corer (USDC) used in this study takes advantage of its ability to drill with low axial force and low power. These advantages overcome some of the major limitations of planetary sampling using conventional drills in low gravity environments. Sensors, such as thermocouple and fiberoptics, are integrated into the bit and used to perform real-time analysis while drilling.
