Saturnian Dawn

NASA's Cassini spacecraft peers toward a sliver of Saturn's sunlit atmosphere while the icy rings stretch across the foreground as a dark band.

This view looks toward the unilluminated side of the rings from about 7 degrees below the ring plane. The image was taken in green light with the Cassini spacecraft wide-angle camera on March 31, 2017.

The view was obtained at a distance of approximately 620,000 miles (1 million kilometers) from Saturn. Image scale is 38 miles (61 kilometers) per pixel.

The Cassini mission is a cooperative project of NASA, ESA (the European Space Agency) and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colorado.

土星黎明

美国航空航天局的卡西尼航天飞机同时朝着土星的阳光充足的气氛,而冰冷的环环绕着前景像一个黑暗的乐队。

在环平面下方约7度,这个视图看向环的未发光侧。 2017年3月31日,卡西尼航天器广角摄像机在绿灯下拍摄图像。

该景观距离土星约62万英里(100万公里)。图像尺度为每像素38英里(61公里)。

卡西尼任务是美国宇航局,欧空局(欧空局)和意大利航天局的合作项目。喷气推进实验室,加利福尼亚理工学院在帕萨迪纳的一个部门负责管理美国宇航局科学任务总局华盛顿的任务。卡西尼轨道器及其两个车载摄像机是在JPL设计,开发和组装的。成像作业中心位于科罗拉多州博尔德的空间科学研究所。
