2012.7.9『格里利庇护地全景』#APOD同步#

你会在寒假做些什么？如果你是火星上的机遇号漫游车，你要花四个月的时间一动不动靠在「格里利庇护地」的边缘——仰着脑袋让你的太阳能板接受尽可能多的阳光。在这次冬季的旅行停留中，平时四处滚动的遥控漫游车执行了好几个科学考察活动，包括捕捉超过800张周围景象的照片，其中很多被合成360度数字压缩全景照片，并用夸张的颜色突出不同地表的特点。机遇号移步的印迹在图中左侧可见，图中底部则是自带防尘板的太阳能板。

在地平线右下方可见「奋斗撞击坑」20公里长的内壁。如今火星北半球的冬天结束了，机遇号继续开始行走，这次将一路向北。奋斗撞击坑内可能拥有还未访问过的火星上最古老的特征之一。漫游车将会探索撞击坑内部，调查异常的浅色土壤块。

What did you do over your winter vacation? If you were the Opportunity rover on Mars, you spent four months of it stationary and perched on the northern slope of Greeley Haven -- and tilted so that your solar panels could absorb as much sunlight as possible. During its winter stopover, the usually rolling robot undertook several science activities including snapping over 800 images of its surroundings, many of which have been combined into this 360-degree digitally-compressed panorama and shown in exaggerated colors to highlight different surface features. Past tracks of Opportunity can be seen toward the left, while Opportunity's dust covered solar panels cross the image bottom. Just below the horizon and right of center, an interior wall of 20-kilometer Endeavour Crater can be seen. Now that the northern Martian winter is over, Opportunity is rolling again, this time straight ahead (north). The rover is set to investigate unusual light-colored soil patches as it begins again to further explore the inside of Endeavour, a crater that may hold some of the oldest features yet visited.
