Knowing which minerals form at different stages of a planet 's evolution , and which depend upon life to be present , are crucial to understanding the mineralogy of other planets and moons .

弄清楚行星演变的不同阶段产生的具体矿物类型，以及哪些矿物是由后来出现的生物体产生的，这对于了解其它行星和月球的矿物学是至关重要的。

All three rovers did spectacular science as well , studying the mineralogy and topography of mars in astonishing detail , and establishing beyond a doubt that water once flowed and pooled on the planet 's surface .

所有三台火星车在科学上也取得了可观的成就，它们从难以置信的细节层次上研究了火星的矿物和地形，不容置疑地证明了水曾经在这颗星球的表面流淌和汇集。

The arm will deposit bits of martian soil into the analytical instruments on the rover 's body , which are known as sam ( sample analysis at mars ) and chemin ( short for chemistry & mineralogy ) .

机械臂将把部分火星土壤储存于探测器上的分析仪器内，这些仪器为火星样本分析仪（sam:sampleanalysisatmars）和化学矿学分析仪（chemin：shortforchemistry&mineralogy）
