At center, Sojourner has traveled off the lander's rear ramp and onto the surface of Mars. 3D glasses are necessary to identify surface detail. The rock Barnacle Bill is to the left of Sojourner, and the large rock Yogi is at upper right. On the horizon sits the rock dubbed "Couch." A deflated airbag sits at lower right.
The image was taken by the Imager for Mars Pathfinder (IMP) on Sol 3. The IMP is a stereo imaging system with color capability provided by 24 selectable filters -- twelve filters per "eye." It stands 1.8 meters above the Martian surface, and has a resolution of two millimeters at a range of two meters.
Mars Pathfinder is the second in NASA's Discovery program of low-cost spacecraft with highly focused science goals. The Jet Propulsion Laboratory, Pasadena, CA, developed and manages the Mars Pathfinder mission for NASA's Office of Space Science, Washington, D.C. JPL is an operating division of the California Institute of Technology (Caltech). The Imager for Mars Pathfinder (IMP) was developed by the University of Arizona Lunar and Planetary Laboratory under contract to JPL. Peter Smith is the Principal Investigator.
