Tsiolokovsky陨石坑内区域的光度模拟结果表明，该区域表面在两个空间尺度上变化很大：建模工作的10 × 10 像素尺度（图像分辨率为~ 0.6 m/像素）和建模参数敏感的毫米到微米尺度。该地区的一些地点与裸露或轻度覆盖的基岩或沉积的细粒风化层相当。总体而言，该区域的表面粗糙度呈双峰分布，而颗粒散射函数呈单峰分布，相函数表现出适度的后向散射性质。单散射反照率呈双峰分布，与火山口底与斜长岩、中央隆起的反照率二元分布相适应。在一些地区，由于重力作用，有风化层运动和分离的迹象。
The photometric modeling results of the region within Tsiolokovsky crater indicate a surface that is highly variable on two spatial scales: the 10 × 10 pixel scale of the modeling effort (image resolution is ∼0.6 m/pixel) and the millimeter to micrometer scale to which the modeling parameters can be sensitive. There are locations within the region that are commensurate with either exposed or lightly covered bedrock or ponded, fine-grained regolith. Overall the surface roughness across this region displays a bi-modal distribution whereas the particle scattering function shows a uni-modal distribution, with the phase function displaying a moderately backward scattering nature. The single scattering albedo is characterized by a bi-modal distribution commensurate with the albedo dichotomy between the crater floor and the anorthositic, central peak uplift. There are indications of regolith movement and segregation due to gravity in some areas.
