Last week, team scientists and the internet alike were amazed when
Perseverance spotted a black-and-white striped rock unlike any seen on Mars
before. Is this a sign of exciting discoveries to come?
毅力号火星车在火星上发现了一道不寻常的条纹岩石
作者：Athanasios Klidaras， 美国太空总署
NASA 的毅力号火星车使用其 Left Mastcam-Z 相机拍摄了这张黑白条纹岩石的图像。
上周，当“毅力号”发现一块黑白条纹岩石时，团队科学家和网络都感到惊讶，这与之前
在火星上看到的任何岩石都不同。这是令人兴奋的发现即将到来的迹象吗？
It has now nearly been a month since the rover began its climb up the steep
slopes leading to the crater rim, on the hunt for ancient rocks that could
teach us about early Martian history. While these tricky slopes made for a
slow initial ascent, drive progress has improved greatly in recent days, as
Perseverance has cruised along a flatter stretch. From this overlook, the
rover can now spot landmarks from earlier in the mission like the iconic
Kodiak butte on the hazy horizon, thick with dust from nearby dust storms.
While driving across unremarkable pebbly terrain, beady-eyed team members
spotted a cobble in the distance with hints of an unusual texture in low
resolution Navcam images, and gave it the name Freya Castle. The team planned
a multispectral observation using the Mastcam-Z camera in order to get a
closer look before driving away.
距离火星车开始爬上通往火山口边缘的陡坡，寻找可以让我们了解火星早期历史的古老岩
石，已经过去了近一个月的时间。虽然这些棘手的斜坡使得最初的上升速度很慢，但最近
几天，随着“毅力号”沿着平坦的路段行驶，驾驶进度已经大大改善。从这个角度来看，
火星车现在可以发现任务早期的地标，例如朦胧地平线上的标志性科迪亚克山，附近沙尘
暴的灰尘很厚。
当开车穿过不起眼的卵石地形时，眼睛睁得大大的团队成员发现远处有一块卵石，在低解
析度的导航摄影机图像中显示出不寻常的纹理，并将其命名为弗雷亚城堡。团队计划使
用 Mastcam-Z 相机进行多光谱观察，以便在出发前仔细观察。
When this data was downlinked a couple days later, after Perseverance had
already left the area, it became clear just how unusual it was. Freya Castle
is around 20 cm across, and has a striking pattern with alternating black and
white stripes. The internet immediately lit up with speculation about what
this "zebra rock" might be.
The science team thinks that this rock has a texture unlike any seen in
Jezero Crater before, and perhaps all of Mars. Our knowledge of its chemical
composition is limited, but early interpretations are that igneous and/or
metamorphic processes could have created its stripes.
几天后，当毅力号已经离开该地区时，当这些数据被下行传输时，人们就清楚地意识到这
是多么不寻常。芙蕾雅城堡宽约 20 厘米，具有醒目的黑白条纹交替图案。网络上立即引
发了关于这块“斑马石”可能是什么的猜测。
科学团队认为这块岩石的纹理不同于以前在杰泽罗陨石坑中看到的任何岩石，甚至可能与
整个火星不同。我们对其化学成分的了解有限，但早期的解释是火成岩和/或变质过程可
能创造了它的条纹。
Since Freya Castle is a loose stone that is clearly different from the
underlying bedrock, it has likely arrived here from someplace else, perhaps
having rolled downhill from a source higher up. This possibility has
researchers excited, and they hope that as they continue to drive uphill,
Perseverance will encounter an outcrop of this new rock type so that more
detailed measurements can be acquired.
Freya Castle is merely the latest in a series of intriguing rocks found
recently. Ever since arriving in the vicinity of the crater rim, the team has
noticed an increased variety of rocks, such as the diverse collection of
boulders at Mount Washburn. Could these be our first glimpses of ancient
rocks uplifted from depth by the Jezero impact, now exposed on the crater
rim? Only time will tell.

由于弗雷亚城堡是一块松散的石头，与下面的基岩明显不同，它很可能是从其他地方到达
这里的，也许是从更高的来源滚下山的。这种可能性让研究人员感到兴奋，他们希望当他
们继续上坡时，毅力号能够遇到这种新岩石类型的露头，以便获得更详细的测量结果。
弗雷亚城堡只是最近发现的一系列有趣岩石中最新的一个。自从到达火山口边缘附近后，
研究团队就注意到岩石的种类不断增加，例如沃什伯恩山的各种巨石。这是否是我们第一
次看到因杰泽罗撞击而从深处升起的古代岩石，这些岩石现在暴露在火山口边缘？只有时
间才能证明一切。
