360-degree color panorama taken by the Imager for Mars Pathfinder over the course of sols 8, 9 and 10. At left is a lander petal and a metallic mast which is a portion of the low-gain antenna. On the horizon the double "Twin Peaks" are visible, about 1-2 kilometers away. Another lander petal is at left-center, showing the fully deployed forward ramp at far left, and rear ramp at right., which rover Sojourner used to descend to the surface of Mars on July 5. Immediately to the left of the rear ramp is the rock Barnacle Bill, which scientists found to be andesitic, possibly indicating that it is a volcanic rock (a true andesite) or a physical mixture of particles. Just beyond Barnacle Bill, rover tracks lead to Sojourner, shown using its Alpha Proton X-Ray Spectrometer instrument to study the large rock Yogi. Yogi, low in quartz content, appears to be more primitive than Barnacle Bill, and appeared more like the common basalts found on Earth.
