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?
毅力號火星車在火星上發現了一道不尋常的條紋岩石
作者：Athanasios Klidaras， 美國太空總署
NASA 的毅力號火星車使用其 Left Mastcam-Z 相機拍攝了這張黑白條紋岩石的圖像。
上週，當「毅力號」發現一塊黑白條紋岩石時，團隊科學家和網路都感到驚訝，這與之前
在火星上看到的任何岩石都不同。這是令人興奮的發現即將到來的跡象嗎？
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.
距離火星車開始爬上通往火山口邊緣的陡坡，尋找可以讓我們了解火星早期歷史的古老岩
石，已經過去了近一個月的時間。雖然這些棘手的斜坡使得最初的上升速度很慢，但最近
幾天，隨著「毅力號」沿著平坦的路段行駛，駕駛進度已經大大改善。從這個角度來看，
火星車現在可以發現任務早期的地標，例如朦朧地平線上的標誌性科迪亞克山，附近沙塵
暴的灰塵很厚。
當開車穿過不起眼的卵石地形時，眼睛睜得大大的團隊成員發現遠處有一塊卵石，在低解
析度的導航攝影機圖像中顯示出不尋常的紋理，並將其命名為弗雷亞城堡。團隊計劃使
用 Mastcam-Z 相機進行多光譜觀察，以便在出發前仔細觀察。
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.
幾天后，當毅力號已經離開該地區時，當這些數據被下行傳輸時，人們就清楚地意識到這
是多麼不尋常。芙蕾雅城堡寬約 20 厘米，具有醒目的黑白條紋交替圖案。網路上立即引
發了關於這塊「斑馬石」可能是什麼的猜測。
科學團隊認為這塊岩石的紋理不同於以前在傑澤羅隕石坑中看到的任何岩石，甚至可能與
整個火星不同。我們對其化學成分的了解有限，但早期的解釋是火成岩和/或變質過程可
能創造了它的條紋。
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.

由於弗雷亞城堡是一塊鬆散的石頭，與下面的基岩明顯不同，它很可能是從其他地方到達
這裡的，也許是從更高的來源滾下山的。這種可能性讓研究人員感到興奮，他們希望當他
們繼續上坡時，毅力號能夠遇到這種新岩石類型的露頭，以便獲得更詳細的測量結果。
弗雷亞城堡只是最近發現的一系列有趣岩石中最新的一個。自從到達火山口邊緣附近後，
研究團隊就注意到岩石的種類不斷增加，例如沃什伯恩山的各種巨石。這是否是我們第一
次看到因傑澤羅撞擊而從深處升起的古代岩石，這些岩石現在暴露在火山口邊緣？只有時
間才能證明一切。
