這些不尋常的火星球體是如何形成的? 2004 年,在火星上機器人 "機遇號 "漫遊車著陸點附近的岩石中發現了數千個由鐵和岩石構成的不尋常的灰色球體,這些球體被稱為 "藍莓"。 為了幫助調查這些球體的來源,"機遇號 "發現了一個被稱為 "漿果碗 "的地表,其凹陷處富含火星球體。 圖中的 "漿果碗 "是火星車在第 48 個火星日拍攝到的。 火星藍莓石的平均大小隻有大約 4 毫米寬。 透過分析最密集的球粒左側岩石表面的圓形斑塊,"機遇號 "獲得的資料顯示,底層岩石的成分與富含赤鐵礦的藍莓大不相同。 這一資訊使人們越來越一致地認為,這些奇特的灰色小球體是從髒水中慢慢沉積下來的。 APOD 30 週年愛爾蘭科克免費公開講座, 6 月 24 日星期二晚 7 點
原文:How were these unusual Martian spherules created? Thousands of unusual gray spherules made of iron and rock and dubbed blueberries were found embedded in and surrounding rocks near the landing site of the robot Opportunity rover on Mars in 2004. To help investigate their origin, Opportunity found a surface dubbed the Berry Bowl with an indentation that was rich in the Martian orbs. The Berry Bowl is pictured here, imaged during rover's 48th Martian day. The average size of a Martian blueberry rock is only about 4 millimeters across. By analyzing a circular patch in the rock surface to the left of the densest patch of spherules, Opportunity obtained data showing that the underlying rock has a much different composition than the hematite rich blueberries. This information contributes to the growing consensus that these small, strange, gray orbs were slowly deposited from a bath of dirty water.
