Viking Lander 2 used its sampler arm to dig these two trenches in the regolith. The shroud that protected the soil collector head during the lander's descent lies a short distance away. The lander's footpad is visible in the lower right corner of the image. The rounded rock in the center foreground is about 20 centimeters (8 inches) wide, while the angular rock farther back and to the right is about 1.5 meters (5 feet) across. The gently sloping troughs between the artificial trenches and the angular rock, which cut from the middle left to the lower right corner, are natural surface features. |
