| 内容記述 | The limited set of high-resolution observations of the 8-12 micron thermal emission from Mars' equatorial regions by the Termoskan instrument onboard the Phobos '88 spacecraft in February and March of 1989 is considered. Observations were also simultaneously acquired in the 0.5 to 1.0 micron region. A combined U.S. and Soviet scientific team made a preliminary quantitative evaluation of about 25 percent of the entire data set. It is found that there is a close agreement with the Viking Infrared Thermal Mapper brightness temperatures, confirming the accuracy of the Termoskan system and calibration. A novel pattern of emission from particles was observed in the morning and assumed to be water or ice. Thermal emission from surface features is varied and distinct down to the limit of resolution. The presence of unusually insulating material has been detected in the uppermost fraction of a millimeter of the Martian surface in places where the shadow of Phobos briefly eclipsed by the surface. |
