Spirit Rover Update

- sol 1152-1158, April 10, 2007:
Spirit is healthy and performing scientific studies of an outcrop of light-toned clasts and cobbles nicknamed "Elizabeth Mahon" on the edge of "Home Plate" as well as a pockmarked rock outcrop nicknamed "Madeline English."
To get around obstacles and make progress over rough terrain using only five wheels, Spirit drove backward a few meters, pivoted around the front wheel, drove backward another few meters, pivoted again to face Madeline English, and finally pushed forward to reach the rock with scientific instruments on the robotic arm.
After investigating Madeline English, the rover will head back north to one of several possible "on-ramps" for driving onto Home Plate.
In addition to daily observations of atmospheric dust levels and surveys of the sky and ground with the miniature thermal emission spectrometer, Spirit conducted the following activities:
Sol 1152 (March 31, 2007): Spirit acquired panoramic camera images of a rock exposure known as "Clara Zaph" in addition to miniature thermal emission spectrometer data from "Clara Zaph 1," "Clara Zaph 2," and "Clara Zaph 3." The rover surveyed the sky and ground and targets known as "Rita Briggs" and "Twila Shively" using the miniature thermal emission spectrometer and completed a survey with the sun low in the sky using the panoramic camera.
Sol 1153: Spirit turned southeast and drove backward 4 meters over the target Elizabeth Mahon to place it within the work volume of the rover's scientific instruments. Spirit acquired post-drive images using the navigation camera and relayed data to the Odyssey orbiter overnight.
Sol 1154: Spirit acquired thumbnail images of the sky using the panoramic camera and measured argon using the alpha-particle X-ray spectrometer.
Sol 1155: Spirit unstowed the robotic arm, placed the M?ssbauer spectrometer on Elizabeth Mahon, and acquired data overnight. The rover acquired a mosaic of panoramic camera images facing the drive direction and relayed data to Odyssey overnight.
Sol 1156: Spirit continued to acquire overnight data from Elizabeth Mahon using the M?ssbauer spectrometer. Spirit acquired full-color images using all 13 filters of the panoramic camera of a target known as "Madeline English 2." The rover acquired miniature thermal emission spectrometer data from Madeline English 2 and targets known as "Betty Hill" and "Madeline English 3."
Sol 1157: Spirit changed tools from the M?ssbauer spectrometer to the microscopic imager and acquired a mosaic of microscopic images of Elizabeth Mahon. The rover placed the alpha-particle X-ray spectrometer on the target and collected data overnight while also relaying relayed data to the Odyssey orbiter. Spirit scanned the sky for clouds using the navigation camera and acquired full-color images of white soil using all 13 filters of the panoramic camera.
Sol 1158 (April 6, 2007): Plans called for Spirit to acquire overnight data using the M?ssbauer spectrometer, panoramic camera images of Madeline English, and miniature thermal emission spectrometer data on targets known as "Noreen Arnold," "Carol Habben," and "Phyllis Wise."
As of sol 1153 (April 1, 2007), Spirit's total odometry was 7,077.10 meters (4.40 miles).
