That statement might raise a few eyebrows. Day or night, temperatures on Venus hover around 850 degrees Fahrenheit, and the atmospheric pressure at the surface is a crushing 1,300 pounds per square inch. The silvery clouds that enshroud the planet consist of sulfuric acid.
这一言论可能会令人侧目。无论是白天还是黑夜,金星上的温度都在850华氏度左右,表面的气压是每平方英寸1300磅。笼罩在金星上的银色云层由硫酸组成。
But go 30 miles above the Venusian surface, and the story is very different. Temperatures are a more tolerable 170 degrees F, and atmospheric pressure is similar to that on Earth. The corrosive clouds are tucked safely below, so there's ample solar energy shining down from above.
但是在距离金星地表30英里的地方,情形就完全不一样了。温度是人类更容易忍受的170华氏度,而大气压力与地球上相似。腐蚀性的云层处于下方对于人类非常安全,有充足的太阳光可以从上面照射。
