The rover, Sojourner, spent several days examining rocks around the landing site. This is an image of the rock, Yogi, taken by the Imager for Mars Pathfinder (IMP) on Sol 3 (July 6, 1997). Sojourner’s wheels studied the mechanics of the soil around Yogi. NASA scientists controlled the force of the wheels upon the soil to learn more about soil composition.
