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/sonic mechanism is currently being developed at JPL to allow probing and sampling of rocks and to use the mechanisms as a sensor platform for in-situ planetary analysis. The technology is based on the novel Ultrasonic/Sonic Driller/Corer (US...

Future NASA exploration missions to Mars, Europa, Titan, comets, and asteroids will perform sampling, in-situ analysis and possibly the return of material to Earth for further tests. One of the major limitations of sampling in low gravity environments is that conventional drills need high axial force. An ultrasonic/sonic driller/corer (USDC) mechanism was developed to address these and other li...

The Tareek Darreh gold deposit is located 40km north of Torbat-e Jaam in the Khorassan-Razavi province, NE-Iran. The study area mainly comprises slightly metamorphosed, sedimentary rocks of Jurassic age including alternation of shale, siltstone, and sandstone. These rocks have been intruded by plutonic rocks such as gabbro-norite, diorite, quartz-diorite, and rhyodacite. The ore bodes are expos...
