It lies about halfway from the rover's landing site, Bradbury Landing, to a location called Glenelg. The team plans to touch the rock with a spectrometer to determine its elemental composition and use an arm-mounted camera to take close-up photographs. Both the arm-mounted Alpha Particle X-Ray Spectrometer and the mast-mounted, laser-zapping Chemistry and Camera Instrument will be used for identifying elements in the rock
