Cassini, a robot spacecraft launched in 1997 by NASA, became close enough in 2002 to resolve many rings and moons of its destination planet: Saturn. At that time, Cassini snapped several images during an engineering test. Several of those images were combined into the contrast-enhanced color composite featured here. Saturn’s rings and cloud-tops are visible toward the image bottom, while Titan, its largest moon, is visible as the speck toward the top. When arriving at Saturn in July 2004, the Cassini orbiter began to circle and study the Saturnian system. A highlight was when Cassini launched the Huygens probe that made an unprecedented landing on Titan in 2005, sending back detailed pictures. Now nearing the end of its mission, Cassini is scheduled to embark on a Grand Finale phase in late 2016 where it will repeatedly dive between the giant planet and its innermost rings.

Cassini是一個由NASA於1997年發射的機器人太空船，於2002年靠近其目的地行星：土星。當時，Cassini進行了幾次工程測試，拍攝了多張影像。幾幅影像被合併成為這幅增強對比度的彩色合成圖。在圖像的底部，可以看到土星的環和雲層，而其最大衛星泰坦則在上方的小點中可見。Cassini於2004年7月抵達土星後，開始圍繞土星系統運行和研究。任務的亮點之一是Cassini發射了Huygens探測器，該探測器於2005年在泰坦上進行了前所未有的著陸，並發回了詳細的圖像。現在，Cassini的任務即將結束，預計將在2016年末展開壯麗的精彩大結局階段，該階段將多次穿越這顆巨行星及其最內側的環。
