This portion of the 360-degree gallery panorama shows Pathfinder's rear ramp, the rock Barnacle Bill at left, and rover tracks leading up to the large rock Yogi. Rover Sojourner is seen using its Alpha Proton X-Ray Spectrometer instrument to study Yogi's composition. Rover tracks and circular patterns in the soil are from Sojourner's soil mechanics experiments, in which varying amounts of pressure were applied to the rover's wheels in order to determine physical properties of the soil.
