NASA is about to launch a fleet of satellites that will help researchers understand how deadly hurricanes develop.
美国宇航局即将发射一队卫星，这将有助于研究人员了解飓风是如何发展的。
The Cyclone Global Navigation Satellite System is made up of eight small spacecraft that are able to take measurements through the rain of a storm's inner eye, which conventional satellites can't do.
气旋全球导航卫星系统由八个小型航天器组成，能够通过风暴内眼的降雨进行测量，这是常规卫星不能做到的。
The tiny satellites will collect data about the hurricane's core — like wind speeds, clouds and rain. Officials hope it will help them better understand how the inside of a storm works.
这些小型卫星将收集飓风核心的数据，如风速，云和雨。官员们希望这将有助于他们更好地了解风暴内部的运作方式。
What scientists know now is a storm's core acts as an engine: It takes energy from warm surface water evaporating into the atmosphere. And that energy is what keeps hurricanes and cyclones going.
现在科学家知道风暴的核心就像一个引擎在运作，温暖的地表水蒸发到大气中提供能量。那种能量保持飓风和气旋前行。
NASA plans to launch the satellites from Cape Canaveral Air Station in Florida on Dec. 12. Once released, the satellites will continuously monitor Earth's oceans around tropical latitudes.
美国宇航局计划12月12日从佛罗里达州卡纳维拉尔角空军基地发射卫星。一旦发射成功，这些卫星将持续监测热带纬度附近的地球海洋。
