Light-toned layered deposits along the floor of Becquerel Crater, an impact crater in Arabia Terra.

光色调沿贝克勒尔陨石坑，在阿拉伯兵马俑陨石坑楼沉积物。

We've spied a moon with a king-size crater. And, other moons pocked with celestial buckshot.

A small impact crater, surrounded by ejecta, is filled in with rippled sand on the floor of Ritchey Crater.

The location of this bright crater is consistent with Earth-based radar images, which suggested a very fresh, rayed impact crater in this area.

这一亮白陨石坑的位置和雷达推测相吻合，地球雷达曾推测这一地区有放射状陨石坑，而这次是第一次看到这一地域。

Pictured above, Telesto's unusually smooth surface was found to show some large craters and boulders, but not the high density of craters found on nearby Tethys or most other Saturnian moons.

在上面影像中，土卫十三不寻常的平滑表面上有一些较大型的陨石坑和圆形团块，但没有像邻近的土卫三或其他的土星卫星一样上面有密密麻麻的陨石坑。

The familiar Sea of Tranquility is the blue area right of center. White lines radiate from the crater Tycho at bottom left, while purplish tones mottle the crater Copernicus left of center.

我们很熟悉的宁静海是中右方的蓝色区域，白色的辐条从左下方的第谷陨石坑伸出，而各式紫色色泽则斑驳地点缀在中左方的哥白尼陨石坑四周。

It is covered with large craters, some with diameters of up to 200 km.

其表面被巨大的陨石坑所覆盖，有些陨石坑的直径可达 200 公里。

Stravinsky is the smooth-floored crater partially seen on the right side of the image that overlies the rim of the larger, rougher crater Vyasa in the center and left.

斯特拉文斯基为右边半部分平坦陨石坑，覆盖在更大而崎岖的Vyasa陨石坑边缘。

In a companion paper, Dr Dale Cruikshank of NASA 's Ames Research Center and colleagues report that Hyperion's surface is quite reflective but the bottoms of the craters are quite dark, similar to those found on the Saturnian moons Phoebe and Iapetus.

在一篇相同主题的论文中，美国航空航天局艾米研究中心的戴尔·克鲁克香克博士及同事报道，土卫七表面反光性相当好，但陨石坑的底部很黑暗，类似在土卫九和土卫八上发现的陨石坑。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
