Our knowledge of Venus's surface is based on distant radar imagery and some startled squawks from an unmanned Soviet probe that was dropped hopefully into the clouds in 1972 and functioned for barely an hour before permanently shutting down.

我们对金星表面的了解，是基于遥远的雷达图像，以及一艘苏联无人探测器发出的一些噪声。那个探测器于1972年满怀希望降落在云团里，运转不到一个小时就永远地关闭了。
