Description
This close-up image of the Mars Exploration Rover Spirit's instrument deployment device, or "arm," shows the donut-shaped plate on the Moessbauer spectrometer. This image makes it easy to recognize the imprint left by the instrument in the martian soil at a location called "Peak" on sol 43 (February 16, 2004). This image was taken by the rover's panoramic camera on sol 39 (February 11, 2004).
