Core samples are typically mm in diameter and mm in length so a typical cut is mm. The drill allows you to obtain cores at an angle of up to between the drill axis guidance vector and the normal to the surface and at an angle of up to to local gravity i.e. above the geographic horizontal. Before drilling the outcrop surface is imaged at high resolution m at a typical distance of cm using a WATSON camera.
The drill is then placed just above the surface of the outcrop with a horizontal drilling Buy Email List error that is usually . mm but sometimes . mm . Once placed two stabilizers on either side of the bit are pressed into the rock surface this is called preloading. The bit then gradually moves into the rock cutting a cylindrical cut into the stone flour. Once drilling is completed the s of the drill body around an axis offset from the center of the sampler destroys the core under the influence of shear pressure.
Finally the crown is removed from the outcrop now with a rock sample inside the inner sample tube. After imaging the bottom of the core i.e. the inner end with the CacheCam the sample is stored in a cache inside the rover body. Because the cylindrical sidewalls of the bit are essentially parallel to the borehole researchers estimate core orientation by orienting the drill itself. Since drill orientation may change slightly during drilling it was decided to select the drills pointing vector orientation immediately after completion of drilling but before unloading the stabilizer as an indication of the average orientation of the cores pointing vector. Lets check the system configuration The processor and memory are fine. The hard drive also meets the specifications.
