在2004年，機械人探測器Opportunity在火星上發現了數千個不尋常的灰色小球，這些球由鐵和岩石組成，被稱為「藍莓」（blueberries）。為了進一步研究它們的起源，Opportunity發現了一個名為「Berry Bowl」的表面，該表面有一個凹陷，富含這些火星珠珠。在機器人探測器的第48個火星日，Berry Bowl的圖片被拍攝下來。這些火星藍莓的平均大小約為4毫米。透過分析岩石表面的一個圓形區域，Opportunity獲得的數據顯示，這些藍莓下方的岩石成分與富含赤鐵礦的藍莓截然不同。這些信息有助於我們達成共識，認為這些小而奇怪的灰色球體是由一層含有雜質的水慢慢沉積而成的。

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.
