The Martian的意思|示意

The rover should have at least one Martian year, to roam the planet, during which time it will collect, grind and analyze around 70 samples of rock and soil.

流浪者至少要待一个火星年，去漫步这个星球，在这期间，它将收集、研磨和分析大约70个岩石和土壤样本。

None of these volcanoes was formed as a result of collisions between plates of the Martian crust—there is no plate motion on Mars.

这些火山没有一个是由于火星地壳板块之间的碰撞而形成的——火星上没有板块运动。

From the small number of impact craters that appear on Martian lava flows, one can estimate that the planet was volcanically active as recently as a half-billion years ago—and may be active today.

从火星熔岩流上出现的少量陨石坑中，我们可以估计，在5亿年前，这个星球上的火山还很活跃——也许现在依然活跃。

The great height of Martian volcanoes is a direct consequence of the planet's low surface gravity.

地球表面低重力直接导致了火星上火山的巨大高度。

Where the Curiosity actually sits is a 96-mile-wide crater named Gale near the Martian equator.

“好奇号”实际所在的位置是火星赤道附近一个名为盖尔的96英里宽的陨石坑。

As on the Moon, the extent of large impact cratering (i.e. craters too big to have been filled in by erosion since they were formed) serves as an age indicator for the Martian surface.

与月球上相同，那些巨大陨石坑的范围（例如，那些巨大到自形成后尚未被尘埃填满的陨石坑）标志着火星表面的年龄。
