SPIRIT UPDATE: Spirit at 'Arad' - sol 715-722, Jan 18, 2006:
Spirit is healthy and is driving as efficiently as possible toward "Home Plate." On the way to Home Plate, Spirit stopped to look at "Arad," where scientists encountered a cluster of white, powdery soil. Researchers decided to stop for a few days and use the robotic arm to conduct some measurements on it. Results are expected soon.
Sol 715 (Jan. 6, 2006): Spirit performed untargeted remote sensing.
Sol 716: Spirit drove 54 meters (177 feet), using a combination of commanded and autonomous navigation.
Sol 717: Spirit drove only 1.38 meters (4.5 feet) on slippery terrain, experiencing slippage of 80 percent as the wheels were turning.
Sol 718: Spirit conducted untargeted remote sensing.
Sol 719: Spirit drove 9.3 meters (30.5 feet). The rover stopped when the slip rate of its wheels exceeded 80 percent in an area of sandy, unfamiliar terrain.
Sol 720: Spirit conducted untargeted remote sensing and atmospheric studies.
Sol 721: Spirit adjusted position to place the robotic arm next to Arad for a weekend of scientific measurements. The rover also used its panoramic camera and miniature thermal emission spectrometer to take images of targets called "Arad1" and "Arad2."
Sol 722: Spirit conducted untargeted remote sensing and took panoramic camera images of tracks created by the rover's wheels.
As of sol 722 (Jan. 14, 2006), Spirit's total odometry was 6,096 meters
