This panorama of images from the Spirit rover, taken on Sol 1925 (June 2,
2009), is helping engineers assess the rover's current state and plan her
extraction from the soft soil in the region now called "Troy." The images
were taken by Spirit's Microscopic Imager (MI) instrument, mounted on the
end of her robotic arm. The MI science investigation is led by Ken
Herkenhoff of the USGS Astrogeology Science Center in Flagstaff.
This is the first time the MI has been used to assist in planning a rover's
escape from an embedding event. The MI isn't intended to take these types
of images--it is designed to focus on targets only 6 centimeters (2.4
inches) in front of its optics. As a result, the images in this mosaic are
well out of focus. Yet despite the focus and the backlighting of the scene,
Joel Hagen (Modesto Jr. College) and colleagues at NASA's Ames Research
Center in California were able process the images to bring out the details
shown here. The mosaic shows the underside of the rover, the depth to which
the wheels are embedded and the terrain itself in sufficient detail to
assess the rover's state.
