The left portion of this image, taken in stereo by the Imager for Mars Pathfinder (IMP) on Sol 3, shows the large rock nicknamed "Yogi." 3-D glasses are necessary to identify surface detail. Portions of a petal and deflated airbag are in the foreground. Yogi has been an object of study for rover Sojourner's Alpha Proton X-Ray Spectrometer (APXS) instrument. The APXS will help Pathfinder scientists learn more about the chemical composition of that rock. This image is part of a 3D "monster" panorama of the area surrounding the landing site.
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.
