📖 逐句对照翻译
The American space agency NASA is preparing to launch a spacecraft to seek more detailed information on water sources on the moon.
美国国家航空航天局（NASA）正准备发射一艘航天器，以获取有关月球上水源的更详细信息。
The spacecraft is an orbiter called Lunar Trailblazer.
该航天器是一个名为“月球开拓者”的轨道飞行器。
It is set to launch later this year, or in early 2025.
它计划于今年晚些时候或2025年初发射。
A SpaceX Falcon 9 rocket will carry the orbiter to space.
一枚SpaceX猎鹰9号火箭将把轨道飞行器送入太空。
That rocket will also transport another moon exploring spacecraft.
那枚火箭还将运送另一艘月球探测飞船。
In a recent statement, NASA said Lunar Trailblazer passed a series of important operational tests.
美国国家航空航天局在最近的一份声明中表示，“月球开拓者”号通过了一系列重要的运行测试。
It is currently completing additional software testing designed to simulate different elements of the trip, or mission.
目前正在完成额外的软件测试，旨在模拟此次旅行或任务的不同环节。
NASA’s Jet Propulsion Laboratory (JPL) is leading the mission, in cooperation with the California Institute of Technology (Caltech) in Pasadena, California.
美国宇航局喷气推进实验室（JPL）正牵头这项任务，并与位于加利福尼亚州帕萨迪纳的加州理工学院（Caltech）合作。
Lockheed Martin Space provided the spacecraft, linked it with the flight system, and supports operations as part of a contract with Caltech.
洛克希德·马丁太空公司提供了该航天器，将其与飞行系统连接，并作为与加州理工学院合同的一部分支持运营。
The spacecraft will use two science instruments to carry out its mission.
该航天器将使用两台科学仪器来执行其任务。
Both instruments are designed to map the moon in search of areas containing water, as well as what forms the water is in.
这两台仪器都旨在绘制月球地图，以寻找含水区域以及水的存在形态。
The two instruments use infrared technology to produce highly detailed mapped images.
这两台仪器利用红外技术生成高度精细的测绘图像。
Lunar Trailblazer weighs about 200 kilograms and measures 3.5 meters with its solar equipment fully deployed.
月球开拓者号重约200公斤，太阳能设备完全展开时长达3.5米。
The spacecraft is set to orbit the moon about 100 kilometers from the lunar surface.
该航天器将在距月球表面约100公里的轨道上绕月飞行。
Several past studies have provided strong evidence that water exists on the moon.
过去有几项研究提供了强有力的证据，证明月球上存在水。
But the evidence has not included exact details on where it is and what forms it might take.
但证据并未包含关于其所在位置及可能采取形式的确切细节。
Scientists believe most of the water is solid, in the form of ice.
科学家认为大部分水是固态的，以冰的形式存在。
But there could be areas where water exists in liquid form, or as a gas in the atmosphere.
但有些区域可能存在液态水，或是以气态形式存在于大气中。
One study released last month suggested that existing water on the moon is more widespread than previously thought.
上个月发布的一项研究表明，月球上现存的水比先前认为的更为广泛分布。
That study was based on new examinations of data collected by India’s Chandrayaan-1 orbiting spacecraft.
这项研究基于对印度“月船1号”轨道飞行器收集的数据的新检验。
NASA has said its search for water on the moon is important because it is seen as a necessary resource for future exploration activities.
美国宇航局表示，其在月球上寻找水资源的工作十分重要，因为这被视为未来探索活动的必要资源。
Astronauts could process it for drinking water, to cool equipment, to create breathable oxygen or even to make rocket fuel.
宇航员可以对其进行处理，用于饮用、冷却设备、制造可呼吸的氧气，甚至制造火箭燃料。
NASA said Lunar Trailblazer will make it easier for future human or robotic science investigators to use the water to see where it first came from.
NASA表示，“月球开拓者”号将使未来的人类或机器人科学调查人员更容易利用这些水，以探究其最初来源。
For example, the presence of ammonia in ice could suggest it came from comets, NASA said.
例如，美国宇航局表示，冰中存在氨可能表明它来自彗星。
The presence of sulfur, on the other hand, could show it rose to the surface from deep inside the lunar interior when the moon was young and volcanically active.
另一方面，硫的存在可能表明，在月球年轻时且火山活动活跃的时期，它从月球内部深处升到了表面。
One of the instruments, the High-resolution Volatiles and Minerals Moon Mapper, was developed by the JPL.
其中一台仪器——高分辨率挥发物和矿物月球测绘仪——由喷气推进实验室研发。
The other, called the Lunar Thermal Mapper, was built by a team at the University of Oxford in Britain.
另一个被称为月球热测绘仪，由英国牛津大学的一个团队建造。
Neil Bowles is an instrument scientist for the Lunar Thermal Mapper.
尼尔·鲍尔斯是月球热成像仪的仪器科学家。
He said in a statement the instrument would center on producing detailed maps of lunar surface temperatures.
他在一份声明中表示，该仪器将专注于绘制月球表面温度的详细地图。
He added that the other instrument will look for a series of signs, called signatures, of water molecules.
他补充说，另一台仪器将寻找水分子的一系列迹象，即特征信号。
“Both instruments will allow us to understand how surface temperature affects water, improving our knowledge of the presence and distribution of these molecules on the moon,” Bowles said.
鲍尔斯说：“这两种仪器都将使我们能够了解地表温度如何影响水，从而增进我们对这些分子在月球上存在情况和分布状况的认识。”
The orbiter is designed to provide scientists with new information about how much movement there is of water molecules on the moon.
该轨道器的设计目的是为科学家提供关于月球上水分子移动量的新信息。
Such movements can be linked to how much sun specific areas receive.
这种运动可能与特定区域接收到的日照量有关。
“Understanding whether water molecules move freely across the surface of the moon or are locked inside rock is also scientifically important,” NASA said in a statement.
美国国家航空航天局在一份声明中表示：“了解水分子是在月球表面自由移动还是被锁在岩石内部，同样具有重要的科学意义。”
Rachel Klima is an investigator for the Lunar Trailblazer spacecraft and its systems at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland.
雷切尔·克里马是马里兰州劳雷尔市约翰斯·霍普金斯应用物理实验室“月球开拓者”号航天器及其系统的研究员。
She said data collected by the instruments can help provide information about where the moon’s water first came from.
她说，仪器收集的数据有助于提供关于月球上的水最初来自何处的信息。
Klima compared such examinations to those involving glaciers that help scientists learn about Earth’s ancient history.
克里马将这些考察比作涉及冰川的考察，后者有助于科学家了解地球的远古历史。
Ice on the moon, she said, “could provide clues as to where that water came from and how and when it got there.”
她说，月球上的冰“可以为这些水来自何处、如何到达那里以及何时到达那里提供线索”。
