Hello. I'm Jim Tedder in Washington. On our program today, fuel prices are about to take a big increase in Indonesia. We'll hear about a mixture of politics and economics. Then diplomacy of a musical kind in Moscow. But first, new scientific details about how the Earth is changing.
吉姆·特德在华盛顿为您报道,在我们今天的节目里,我们将谈谈印尼即将大幅度上涨的燃油价格。我们还将听到系列有关政治和经济的报道,然后是莫斯科的一种音乐外交。不过首先,让我们了解下有关地球变化的最新科学信息。

Under normal conditions, NASA, the United States Space Agency, looks out there for new information about our universe. But lately researchers have been aiming complex devices at Earth. They hope to find out how healthy, or unhealthy, our planet is.
在一般情况下,美国宇航局(NASA)会向太空观测以了解我们的宇宙。但最近,研究者们开始将复杂的仪器对向了地球,希望了解我们的地球究竟有多健康或不健康。

These scientific tools were designed to learn about water on the moon, and rocks on Mars. Now they can help us understand how volcanoes, wildfires, and even the severe lack of rain affect our home. The instruments gather information called a "spectral fingerprint" about how light interacts with the land. Robert Green is the NASA scientist in charge of the project.
这些科学仪器专门用来了解月球上的水和火星上的岩石的,如今,它们被用来帮助我们了解火山爆发、野火甚至严重缺少降水对地球的影响。这些仪器收集名为“光谱指纹”的信息,了解光如何与地面相互作用。罗伯特·格林是美国航天局该项目的负责人。

"We can see the interaction of the molecules that are present in the earth's atmosphere, such as water vapor and carbon dioxide, and on the earth's surface in plants such as cellulous and leaf water and the other constituents of plants."
“我们可以了解地球大气层中分子的互动,比如水蒸气和二氧化碳,以及地球表面植物体内多细胞水分和叶片水分与植物其他部位水分的互动情况。”

The scientific instruments were tested in high flying airplanes over the state of California. NASA plans to put them in a permanent Earth orbit, about 700 kilometers high, after the testing is complete. Mr. Green says the devices help scientists discover a great amount of information that the human eye cannot see.
研究者在加州上空飞行的飞机中用这些仪器做测试,NASA计划在测试结束后将这些仪器永久性地放置在地球轨道,大约距离地面700千米。格林说这些设备将帮助科学家了解人类肉眼无法看到的情况。

Mr. Green's program is called the "Hyperspectral Infrared Imager Airborne Campaign." The testing will continue through next year. After the instruments are put into orbit around Earth, scientists will compare information from the last year to learn how the Earth is changing. This could allow policy makers to make better decisions, so we humans can learn how to adjust to new environmental conditions.
格林的项目名为“高光谱红外成像仪机载运动”,测试将持续到明年。在把仪器放到地球轨道后,科学家将对比去年的数据,以分析地球的变化。这样政府就可以做出更好的决策,这样人类就可以知道在新的环境状况下如何调节。

Indonesian officials are expected to cut fuel subsidies soon by 44 percent. If that happens, fuel prices will increase. Economists say the payments are a costly expense that adds to Indonesia's dependence on foreign oil imports. But these assistance payments by the government remain politically popular, and politicians are worried about the public's reaction. June Simms tells us more.
印尼官方有望将燃油补贴削减44%,这样一来,燃油价格就会上涨。经济学家说这笔开支很大,使得印尼更加依赖外国进口石油。但在政治上看来,印尼政府的这笔援助仍很受欢迎,政客们担心公众的反应。June Simms报道。
