Summaryedit
Description |
English: Iapetus as seen by the Cassini probe.
Original NASA caption: Cassini captures the first high-resolution glimpse of the bright trailing hemisphere of Saturn's moon Iapetus. Français : Japet vu par la sonde Cassini.
Traduction de la légende originale fournie par la NASA : Cassini obtient la première vue à haute résolution du brillant hémisphère arrière de Japet, une lune de Saturne. 中文: 卡西尼探测器看到的土卫八.
NASA最初的标题: 卡西尼捕捉到的第一幅高分辨率土卫八明亮的拖尾半球的图像. 这个伪色拼图显示了土卫八的整个半球 (跨越 1,468 km), 该半球可以在[卡西尼号于2007-09遇到该双色卫星时的伸出去的腿]上看到. 拖尾半球的中心经度是拼图中心向左 24 度. 该图还显示了暗的领头半球和亮的拖尾半球之间的复杂的过渡区域. 这个区域可沿图像右部看到, 并且在卡西尼接近最近路线时获得的很多图像中都能看到. 这里第一次在细节上显露了拖尾半球标志性的地质学结构. 这个区域看上去极为多坑, 尤其在北南两个极区. 接近拼图顶部, 许多撞击面貌可以在NASA的航行者2号飞船1981获得的图像中看到, 包括撞击坑Ogier和撞击坑Charlemagne. 这个视图中最突出的地貌是, 拼图的下半部, 一个 450 km 宽的撞击盆地, 在土卫八上至少有九个这样的大盆地. 实际上, 该盆地覆盖了一个更早的盆地, 即新盆地的东南方的那个尺寸相近的盆地.<br> 在很多地方, 暗的物质看上去覆盖了赤道 斜坡 和 坑底. 这些暗的物质推测成分是氮轴有机化合物即氰化物 水合矿物 和 其他含碳矿物. 跨越拖尾半球的明亮物质的分布和颜色变化, 将是至关重要的线索, 让我们去理解 土卫八的罕见的亮暗双重人格的起源. :) 视图由卡西尼太空船窄角度相机于 2007-09-10 获得, 相机距离土卫八大约 73,000 km . 此有色视图扩展了人眼视觉电磁波谱可见的波长. 暗材料的强烈的红褐色调远远不是真色图具有的. 增强色的采用使得暗材料的红属性比单纯人眼所见更显著. 该拼图来自跨越土卫八的表面的 60 个图像 覆盖了 15 个脚印 (基本测绘区域). 该视图是一个正射投影, 中心位于南纬10.8度, 西经246.5度, 分辨率为 426 米/像素. 一个正投影视图很像遥远的观察者通过望远镜所看到的情景. 每个脚印上, 全分辨率清晰过滤图由半分辨率图像组合而成, 这些半分辨率图像以红外 绿 和紫外光谱过滤器拍摄, 这些过滤器的中心波长分别是 752 nm, 568 nm 和 338 nm. 卡西尼-惠更斯任务是 NASA 欧洲空间局 和 意大利空间局的协作工程. JPL喷气推进实验室, 是加利福尼亚技术学院的一部分. 喷气推进实验室为华盛顿特区的NASA科学任务理事会管理着该工程. 卡西尼轨道器及其两个相机在喷气推进实验室设计开发和组装. 图像处理中心建于空间科学研究所(位于 Boulder, Colo). (译者注: California Institute of Technology in Pasadena, 或者翻译成加州工学院, 但不要翻译成什么 '理工大学' 那样太没谱了. 名词 '技术学院' 不同于中国大陆的技工职业教育院校专用的 '技术学院'. 技术一词应该是不分大小的真正的技术 而非中国大陆普遍认为并在传统上轻视的 '小小的技术'.) |
