ResumoThe fine lunar surface material at the Surveyor 3 landing site has about 3 × 103-dyne/cm2 cohesion, 35° angle of internal friction, 3 × 105-dyne/cm2 static bearing capacity. A small rock withstood a local pressure of 2 × 107 dynes/cm2. Soil strength and density increase significantly at depths of a few centimeters. Exposed surface has a considerably higher albedo than the material just below it. The photometric function changed when the surface was slightly compressed. Fine surface material appears to be gradually moving downslope.
