给出了水手10号在11 μm和45 μm下水星表面的红外亮度温度。这些数据是在第一次沿着从当地时间17小时到当地午夜到当地时间9小时的赤道带状带飞行时获得的。假设发射率为0.9，导出的地表热惯量在0.0031 ~ 0.0031 cal cm−2sec−1 2K−1之间，在经度270°处暖极的隐含最小黎明前地表动力学温度接近93 K。观测到几个明显的热不均匀性，其中一个似乎与高雷达反射率区域一致。所得的热性能、电趋肤深度和损耗正切值落在月球上发现的值范围内。
Mariner 10 infrared brightness temperatures of the surface of Mercury at 11 and 45 μm are presented. The data were obtained during the first flyby along a nera-equatorial swath extending from 17 hours local time through local midnight to 9 hours local time. For an assumed emissivity of 0.9, derived surface thermal inertias are between 0.0031 and 0.0031 cal cm−2sec−1 2K−1and the implied minimum predawn surface kinetic temperature for the warm pole at longitude 270° is near 93 K. Several pronounced thermal inhomogeneities were seen, one of which appears to coincide with a region of high radar reflectivity. The derived thermal properties and the electrical skin depth and loss tangent fall within the range of values found on the Moon.
