用“好奇号”迄今为止最清晰的全景探索火星
Have you ever wanted to explore Mars? Well, NASA is giving you the closest thing to it without leaving the comfort of your own home. The space agency has released a stunning 1.8-billion-pixel image of a sweeping Marscape taken by Curiosity late last year.
你曾经想探索火星吗?NASA给了你最接近它的东西，而不用离开舒适的家。美国宇航局近日公布了一幅令人震惊的18亿像素的火星全景图像，这幅图像是去年年底由“好奇号”拍摄的。
The panorama is a composite of over 1,000 pictures of a region called Glen Torridon, on the side of Mount Sharp, where Curiosity is currently stationed. The mission team took the opportunity presented by a reduced workload during the Thanksgiving holiday to focus on the panorama you can now explore.
这幅全景图是由1000多张名为Glen Torridon的地区的照片合成而成，该地区位于夏普山的一侧，“好奇号”目前就驻扎在那里。任务团队利用感恩节期间工作量减少的机会，专注于你现在可以探索的全景。

Between November 24 and December 1, Curiosity’s Mastcam used its telephoto lens to snap the pictures. It operated only between 12 and 2pm local time, so that the lighting conditions were more or less constant, and it took six and a half hours to complete. It is rare that Curiosity has the same vantage point and the time to do something like this, so it couldn't be missed.
在11月24日至12月1日之间，“好奇号”的桅顶照相机用长焦镜头抓拍了这些照片。它只在当地时间12点到下午2点之间运行，因此照明条件或多或少是恒定的，完成它需要6个半小时。“好奇号”很少有这样的有利位置和时间来做这样的事情，所以它不会被错过。
"While many on our team were at home enjoying turkey, Curiosity produced this feast for the eyes," said Ashwin Vasavada, Curiosity's project scientist at NASA's Jet Propulsion Laboratory, in a statement. "This is the first time during the mission we've dedicated our operations to a stereo 360-degree panorama."
美国宇航局喷气推进实验室的“好奇号”项目科学家阿什温·瓦萨瓦达在一份声明中说:“当我们团队中的许多人在家享用火鸡时，‘好奇号’却为我们带来了一场视觉盛宴。”“这是我们第一次在执行任务期间致力于立体360度全景。”
Use your fingers or mouse to zoom in and out and drag around to explore the panorama in incredible detail.
The last high-resolution panorama from Curiosity was taken in 2013 and was a 1.3-billion-pixel image from the base of Gale Crater, showing Mount Sharp, the mission's target of exploration, on the hazy horizon.
“好奇号”最后一张高分辨率全景照片拍摄于2013年，是盖尔陨石坑底部的一张13亿像素的图片，显示了在朦胧的地平线上探索任务的目标——夏普山。
Curiosity has pottering and taking pictures (and selfies) on Mars since August 6, 2012 and has covered just over half the distance of a half marathon (21 kilometers/13 miles) across the Red Planet. Not bad for a rover whose top speed on flat ground is 0.14 kilometers per hour (0.09 miles per hour).
从2012年8月6日起，“好奇号”就开始在火星上漫步、拍照(和自拍)，目前它已经完成了半个马拉松(21公里/13英里)的一半路程。对于在平地上最高速度为每小时0.14公里(每小时0.09英里)的火星车来说，这已经很不错了。
