Now from the Boston Museum of Science Sci-tech today on NECN.
有線新聞波士頓消息。
We are headed to the moon on Sci-tech today. NASA recently launched two robotic missions in an effort to learn more about the moon and its environment. Joining us now from the Museum of Science Boston is researcher Tony Case, a graduate student at Boston University. Good to have you with us, Tony. Good to be here, thanks for having me.
今天我們來關注的是關于月球的消息，美國國家航空和宇宙航行局（NASA）近期投放了兩枚人造衛星以探知月球及其周圍環境。來自波士頓大學的研究生Tony Case將和我們一起解讀這則消息。很高興見到你，Tony。謝謝，很高興來到這兒。
So what can you tell us about these missions?
那么，對于這項月球任務你知道多少呢？
Well, LRO is a spacecraft that's around the moon right now. It's orbiting really close to the surface. It's about 30 miles above the surface of the moon. And there're seven instruments on the spacecraft, they are all taking a wide array of measurements of the entire surface of the moon. Along with LRO launching on the same rocket was another spacecraft called LCROSS, which is on its way to the moon now. And the main goal of both of these missions was basically that open an advance scout to gather information that might enable us go back to the moon more safely and more easily in the future if we choose to do so with manned missions.
目前，月球勘測軌道器（Lunar Reconnaissance Orbiter，簡稱LRO）正在沿著月球表面運行。這顆人造衛星距離月球表面只有30英里，它所承載的7種相關儀器正在對月球進行一系列的探測。與LRO一同發射的還有月球坑觀測和傳感衛星(Lunar Crater Observation And Sensing Satellite，簡稱LCROSS) ，現在正在逐漸靠近月球。這兩項月球計劃旨在收集更多的信息，為將來月球的載人探測任務提供更安全舒適的保障。
Interesting, alright in the long names of these, the Lunar Reconnaissance Orbiter is the LRO and the Lunar Crater Observation and Sensing Satellite is LCROSS.That's right.
有趣的是，LRO代表著月球勘探器，LCROSS表示月球坑觀測和傳感衛星。是的。
What kind of information do we need to get from these satellites to help us to someday return to the moon.
從這兩顆人造衛星的名稱就能看出我們為將來成功登月正在收集什么樣的信息。
Well LRO is giving us a lot of different information and the one piece of information that is personally close to my heart is the instrument that I worked on and what it measures is radiation—the radiation environment around the moon. So this radiation is, it's energetic particles that are coming from outside of the solar system and also from our own sun. And it can cause damage both to human cells and to electronics. So this is the instrument we built to measure that radiation. It's called CRATER — the Cosmic Ray Telescope for the Effects of Radiation. So this is around the moon now this is a testing version but the flight model is around the moon. And it's measuring the radiation right now.
LRO發回了許多信息，其中一條我最關心的，也是我正在研究的就是測量輻射的儀器。輻射是來自外太陽系和太陽本身的能量分子，它能傷害人類的細胞，同時對通信行業也有影響。這是我們發明的輻射測量儀，叫做CRATER（Cosmic Ray Telescope for the Effects of Radiation），但這只是測試版，正式版正在人造衛星上測量輻射強度。
All right, and that was developed at BU and MIT.
是波士頓大學和麻省理工學院兩所大學研發的。
It was, yeah, along with other institutions ,but yeah it was headed here in Boston.
恩，是的，聯合了其它大學共同研發，但是是由波士頓大學帶頭的。
Pretty exciting. What about water? They are looking for water and how important it is to find it or not find it?
很有趣。那么水呢？科學家們正在月球上尋找水源，能不能找到水源有多重要呢？
Well yeah.That's one of the main goals of both the LRO mission and the LCROSS mission to find water along with any other resources that we might be able to use. So LRO is..ha..has different imagers that are taking images of the surface that might tell us whether there is water there, and also the LCROSS spacecraft is designed almost exclusively to search for this water. So LCROSS has it launched along with LRO on the same rocket and when we detached from LCROSS, it stayed attached to the empty fuel tank left over from the rocket. So tomorrow morning about 7:30 in the morning LCROSS releases the fuel tank. The fuel tank flies in to the surface of the moon, impacts and throws up a huge dust cloud. So hopefully in this dust cloud, will be dust along with anything else that might have been mixed in along with the regulus on the moon in the soil. And so as LCROSS flies to this dust could, it's able to measure everything that's in that dust hopefully confirming the presence of water.
是的，LRO和LCROSS的發射最主要的目的就是尋找水源，這兩顆人造衛星傳回的數據結合其他數據我們也許就能加以判斷。LRO的成像器會拍攝月球表面的照片，LCROSS幾乎就是專門用來探測水源的。在LCROSS和LRO從發射火箭中分離后，LCROSS仍舊和空的燃料罐綁定。明天早上7:30，LCROSS將會釋放燃料罐，燃料罐撞擊月球形成大量塵埃云，月球表面的銻和其他物質就會被揚起，在LCROSS靠近的過程中就會分析塵埃云中的物質，希望我們可以證明水的存在。
ll right very very interesting, TONY CASE, a graduate student of BU. Thanks very much for joining us. Thanks a lot.
真的是非常有趣，TONY CASE，波士頓大學的一名研究生。感謝你的介紹。謝謝。
And we will let people know that tomorrow at the Museum of Science from 9 to 1 you can watch a video of LCROSS impact and see presentations by the CRATER team they will be on hand to answer questions about LRO and LCROSS and to demonstrate the instrument.
我們要告訴觀眾們的是，明天9點到下午1點科技博物館將放映LCROSS撞擊的錄像，CRATER研究組會到現場展示探測儀器并解答您的問題。
taking a wide array of measurements: 做各類測試
