Heatshield on the Horizon NASA

The Mars Exploration Rover Spirit acquired this panoramic camera image mosaic on the 68th martian day, or sol, of its mission (March 12, 2004). The reflective speck about 200 meters (650 feet) away, on the far crater rim, was immediately a point of interest for scientists and engineers alike. They soon were able to identify it as Spirit’s protective heatshield.
