Unusual Bright Soil on Mars

Explanation: What is this bright soil on Mars? Several times while rolling across Mars, the treads of the robotic rover Spirit have serendipitously uncovered unusually bright soil. Spirit uncovered another batch unexpectedly last month while rolling toward its winter hibernation location on McCool Hill. The physics and chemistry instruments on Spirit have determined the soil, shown above, contains a high content of salts including iron-bearing sulfates. A leading hypothesis holds that these salts record the presence of past water, with the salts becoming concentrated as the water evaporated.

解释：在火星上的这些明亮的土壤是什么?在好几次行走于火星时，精神号漫游车的轮迹里都有着偶然暴露在外异常明亮的土壤。在它上个月开往位于麦库尔山的冬眠地点时. 精神号意外地发现另一处明亮土壤。在精神号上的物理和化学仪器检测了如上所示的土壤,有着高浓度的硫酸铁盐。一个主流的假说认为, 这些盐份记录着过去曾经存在的水, 而当水份蒸发后便浓缩变成盐份.[翻译：夜空]

不错！为了更醒目，我把你翻译的文字改成彩色，你看如何？
另外，精神号就是过去我们所说的勇气号吧？

是的，精神和勇气，在英文里好像都是同一个单词，我见别家译成精神号，我就把原来翻译的勇气号改过来了。
