The reflection spectrum for the integral disk of the planet Mercury was measured and was found to have a constant positive slope from 0.32 to 1.05 micrometers, except for absorption features in the infrared. The reflectivity curve matches closely the curve for the lunar upland and mare regions. Thus, the surface of Mercury is probably covered with a lunar-like soil rich in dark glasses of high iron and titanium content. Pyroxene is probably the dominant mafic mineral.
对水星整体圆盘的反射光谱进行了测量,发现其在0.32至1.05微米范围内具有恒定的正斜率,但在红外区域存在吸收特征。反射率曲线与月球高地和月海区域的曲线非常匹配。因此,水星表面可能覆盖着富含高铁和钛含量深色玻璃的类似月球的土壤。辉石可能是主要的镁铁质矿物。
