This view of the rock "Chimp" was acquired by the Sojourner rover's left front camera on Sol 74 (September 17). A large crack, oriented from lower left to upper right, is visible in the rock. A dark crust appears to cover Chimp in some areas whereas other parts of the rock have a lighter shading. A boundary between the two regions is clearly seen in the upper left part of Chimp.

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).
Photojournal note: Sojourner spent 83 days of a planned seven-day mission exploring the Martian terrain, acquiring images, and taking chemical, atmospheric and other measurements. The final data transmission received from Pathfinder was at 10:23 UTC on September 27, 1997. Although mission managers tried to restore full communications during the following five months, the successful mission was terminated on March 10, 1998.
