“勘测者5号”的地表物质呈颗粒状，有轻微的粘性。当飞船在着陆过程中滑行时，航天器脚垫在这种材料上犁出了沟槽。对于可压缩土壤模型，2.7牛顿/厘米^2的静态承载能力与观测结果最吻合。游标引擎对表面移动的表面粒子的静态发射；一个直径20厘米，深约1厘米的陨石坑显然是在发动机关闭时产生的。土壤对气体的渗透率为1 × 10^(−8)cm^2，深度约为25 cm，对应于土壤颗粒大多为2 ~ 60 μ直径。
The surface material at the Surveyor 5 site is granular and slightly cohesive. Spacecraft footpads plowed trenches in this material as the spacecraft slid during landing. For a compressible soil model, a static bearing capacity of 2.7 newtons/cm^2 gave best agreement with the observations. Static firing of the vernier engines against the surface moved surface particles; a crater 20 cm in diameter and about 1 cm deep was produced, apparently at engine shutdown. The permeability of the soil to gases, to a depth of about 25 cm, is 1 × 10^(−8) cm^2, corresponding to soil particles mostly 2 to 60 μ in diameter.
