Why is this giant crater on Mimas oddly colored?
土卫一上这个巨型环形山为什么有这么古怪的颜色？
The color difference could yield surface composition clues to the violent history of Mimas.
颜色差异可能提供土卫一表面组成的线索以了解其动荡的历史。
On moon Mimas, the enormous Herschel Crater spans 80 miles (130 kilometers) -one-third of the moon's entire surface.
在土星的卫星土卫一上，巨大的赫歇尔陨石坑跨越了80英里(130公里)，占据了这个卫星整个表面的三分之一。
An impact on Mimas much larger than the one that created the 130-kilometer Herschel would likely have destroyed the entire world.
一个比创造了130千米赫歇尔环形山更大的撞击很可能会毁了整个土卫一。
Mimas, one of the smaller round moons of Saturn, sports Herschel crater, one of the larger impact craters in the entire Solar System.
土卫一，土星的一颗较小的卫星，却炫耀着全太阳系最大的撞击坑之一的赫歇尔环形山。
Small moon Mimas is just touching Saturn's disk near the ring plane at the far right.
土卫一位于最右侧光环附近，紧贴着土星盘面。
Below Titan, near the ring plane and to the left is the moon Mimas, casting a muchs maller shadow onto Saturn's equatorial cloud tops.
泰坦左下靠近土星光环的是土卫一弥玛斯，在土星赤道云层上投下小得多的投影。
During the flyby, Cassini also captured the highest-resolution temperature map of Mimas, revealing an unexpected pattern of warm regions reminiscent of the arcade icon Pac-Man.
在卡西尼号此次掠过土卫一飞行期间，它还捕获了土卫一高清晰的温度图谱，可以揭示其温暖地区令人意想不到的模式，而这张图能令人回忆起幼时常玩的“吃豆小精灵”。
Mimas, one of Saturn's innermost moons, was another of Cassini's targets--which is fitting because Mimas looks rather like a bulls-eye, thanks to the huge circular crater on its surface.
土卫一“米玛斯”是土星最里面的卫星之一，也是“卡西尼”号的一个重点观测目标。由于表面的巨大环形陨坑，土卫一看上去好似一只牛眼。
The natural color of Mimas visible to the human eye may be a uniform gray or yellow color, but this mosaic has been contrast-enhanced and shows differences at other wavelengths of light.
人眼所见土卫一的自然颜色可能是均匀的灰色或黄色，但这张拼接图经过了增强对比度，以显示其他波长的光的差异。
Subtle color differences on Saturn's moon Mimas are apparent in this false-color view of Herschel Crater captured by NASA's Cassini spacecraft during its closest-ever flyby of that moon.
这是土星的卫星土卫一(米玛斯)上赫歇尔环形山的假彩色照片，由NASA的卡西尼飞船在最接近土卫一飞行的时候拍摄，照片上细微的颜色差别很明显。
