Photo: This image of the rock "Flat Top" was taken from the left of the Sojourner rover's front cameras on Sol 42. Pits on the edge of the rock and a fluted surface are clearly visible. The rocks in the left background constitute the Rock Garden. 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.
