Spirit completed a campaign of using the tools on its robotic arm to examine the feature "Cliffhanger." Spirit scuffed the soil using its wheels in the area around Cliffhanger, and then observed both the scuffed and undisturbed soil.
In addition, Spirit imaged the moons Phobos and Deimos at night. Spirit also acquired part one of a stereo panorama.
