给出了火星初步的10和20μm亮度温度。超过35%的火星表面被观测到分辨率高于100公里。总体而言，结果证实了水手6号和7号辐射计得出的热性质，尽管平均而言，沙尘暴期间温度较低，相对于火星白天发生了变化。许多地区都得出了热惯性和辐射反照率；这些性质之间没有明确的相关性。在辐射计的空间极限处再次发现热结构，没有发现需要调用内部热源的情况。
Preliminary 10- and 20-μm brightness temperatures of Mars are presented. More than 35% of the Martian surface was observed with a resolution better than 100 km. On the whole, the results confirm the thermal properties derived from the Mariner 6 and 7 radiometers, although the temperatures, on the average, were cooler and shifted with respect to the Martian day during the dust storm. Thermal inertias and radiometric albedos were derived for many areas; no clear correlation exists between these properties. Thermal structure again was found at the spatial limit of the radiometer; no cases were found in which it was necessary to invoke internal heat sources.
