Original Caption Released with Image:

One of the two forward cameras aboard the Sojourner rover took this image of the Sagan Memorial Station on Sol 26. The angular resolution of the camera is about three milliradians (.018 degrees) per pixel, which is why the image appears grainy. The field of view of each rover camera is about 127 degrees horizontally and 90 degrees vertically.

Features seen on the lander include (from left to right): the Atmospheric Structure Instrument/Meteorology Package (ASI/MET) mast with windsocks; the low-gain antenna mast, the Imager for Mars Pathfinder (IMP) on its mast at center; the disc-shaped high-gain antenna at right, and areas of deflated airbags. The dark circle on the lander body is a filtered vent that allowed air to escape during launch, and allowed the lander to repressurize upon landing. The high-gain antenna is pointed at Earth. The large rock "Yogi," which Sojourner has approached and studied, as at the far right of the image. "Mini Matterhorn" is the large rock situated in front of the lander at left.

The horizontal line at the center of the image is due to differences in light-metering for different portions of the image. The shadow of Sojourner and its antenna are visible at the lower section of the image. The antenna's shadow falls across a light-colored rock.

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 and 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.

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.
