[酷图] 火星岩石上神秘的斑斑点点

这是“机遇”号火星车传回的显微图片，NASA经过了增强色的处理。图片的效果是夸大的，但是我们可以清楚的看到火星岩石上的有一些神秘的斑斑点点。

PIA05236: Speckled with Spherules

This false-color image taken by the panoramic camera onboard the Mars Exploration Rover Opportunity highlights the spherules, or tiny spheres, that speckle the rock dubbed Stone Mountain. The colors in this picture were exaggerated or stretched to enhance the real difference in color between Stone Mountain and its collection of granular spherules.

:eek:

这是未经颜色处理的照片。另外，这张图片中标有方形的区域是“机遇”号火星车的的机械臂进行探测的地方。

PIA05237: Mars Rock Formation Poses Mystery

该区域的特写照片！

This sharp, close-up image taken by the microscopic imager on the Mars Exploration Rover Opportunity's instrument deployment device, or "arm," shows a rock target dubbed "Robert E," located on the rock outcrop at Meridiani Planum, Mars. Scientists are studying this area for clues about the rock outcrop's composition. This image measures 3 centimeters (1.2 inches) across and was taken on the 15th day of Opportunity's journey (Feb. 8, 2004).

PIA05238: Mars Rock Formation Poses Mystery-2:eek:

This sharp, close-up image taken by the microscopic imager on the Mars Exploration Rover Opportunity's instrument deployment device, or "arm," shows a rock target dubbed "Robert E," located on the rock outcrop at Meridiani Planum, Mars. Scientists are studying the spherule, or small sphere, in the center of the image that appears to be protruding from the rock formation. This image measures 3 centimeters (1.2 inches) across and was taken on the 15th day of Opportunity's journey (Feb. 8, 2004).

这是什么啊？
会不会就是小石子颗粒`~

很象珊瑚礁
