Cassini's Titan Radar Mapper imaged the surface of Saturn's moon Titan on its February 2005 fly-by (denoted T3), collecting high-resolution synthetic-aperture radar and larger-scale radiometry and scatterometry data. These data provide the first definitive identification of impact craters on the surface of Titan, networks of fluvial channels and surficial dark streaks that may be longitudinal dunes. Here we describe this great diversity of landforms. We conclude that much of the surface thus far imaged by radar of the haze-shrouded Titan is very young, with persistent geologic activity.
卡西尼号的泰坦雷达测绘仪在2005年2月飞越土星卫星泰坦时(标记为T3)对其表面进行了成像,收集了高分辨率合成孔径雷达以及更大尺度的辐射测量和散射测量数据。这些数据首次明确识别出土星卫星泰坦表面的撞击坑、河流渠道网络以及可能是纵向沙丘的表面暗条纹。在此,我们描述这种多样的地形地貌。我们得出结论,到目前为止,雷达所成像的被阴霾笼罩的泰坦表面大部分都非常年轻,存在持续的地质活动。
