Slightly Beneath Saturn's Ring Plane

Explanation: When orbiting Saturn, be sure to watch for breathtaking superpositions of moons, rings, and shadows. One such picturesque vista was visible recently to the robot Cassini spacecraft now orbiting Saturn. In late February, Cassini captured a Rhea, the second largest moon of Saturn, while looking up from slightly beneath Saturn's expansive ring plane. Signature dark gaps are visible in the nearly-edge on rings. A shadow of Saturn's F ring cuts across the cratered ice-moon. Cassini is scheduled to continue sending back images from the orbit of Saturn until at least 2008.

土星环下的景色
解释：当在土星轨道运行时，一定要记得看看土卫，光环，还有阴影的惊人重叠。这幕美丽如画的景色被卡西尼最近在绕土星运行时看到了。2月底，当卡西尼从土星广阔的光环平面向上看时，捕捉到土卫五这颗土星第二大的卫星。以及光环的边缘和黝黑的环缝。土星F环的阴影径直穿过那坑坑洼洼的冰卫星。卡西尼计划会一直在绕土星运行的轨道上传送图片回来至少直至2008年。[翻译：夜空]
