📖 逐句对照翻译
NASA says a spacecraft that has been examining the sun’s outermost atmosphere recently got closer to our Earth’s star than any past explorer has.
美国国家航空航天局表示，一艘一直在研究太阳最外层大气的航天器最近比以往任何探测器都更接近我们的恒星。
The American space agency announced its Parker Solar Probe passed within 6.1 million kilometers of the sun’s outer corona on December 24.
美国航天局宣布，其帕克太阳探测器于12月24日飞越了太阳外日冕层，距离仅为610万公里。
Mission leaders established communication with the spacecraft after the operation and said the orbiter was safe.
任务负责人在操作后与航天器建立了通信联系，并表示轨道器状态安全。
NASA launched the Parker Solar Probe in August 2018.
美国宇航局于2018年8月发射了帕克太阳探测器。
Its mission is to study the sun’s powerful corona and solar wind.
它的任务是研究太阳强大的日冕和太阳风。
Solar wind is created by a continuous flow of charged particles, called plasma, into space from the corona.
太阳风是由日冕持续向太空流出的带电粒子流（称为等离子体）产生的。
In 2021, NASA announced the orbiter had passed into the solar atmosphere for the first time.
2021年，美国宇航局宣布该轨道飞行器首次进入太阳大气层。
Researchers said at the time, the spacecraft had successfully “touched” the sun.
研究人员当时表示，该航天器已成功“触摸”到太阳。
Parker was believed to be about 13 million kilometers from the center of the sun when it crossed over into the sun’s outer atmosphere.
帕克探测器进入太阳外层大气时，据信距离太阳中心约1300万公里。
In a statement, NASA’s Associate Administrator Nicky Fox praised the spacecraft’s latest pass-by of the sun.
在一份声明中，NASA副局长妮基·福克斯赞扬了该航天器最近一次飞掠太阳的行动。
“Flying this close to the sun is a historic moment in humanity’s first mission to a star,” she said.
她说：“如此近距离地飞掠太阳，是人类首个恒星探测任务中的历史性时刻。”
Fox leads the agency’s Science Mission Directorate at NASA Headquarters in Washington, D.C.
福克斯在华盛顿特区的NASA总部领导该机构的科学任务理事会。
The Parker Solar Probe is believed to have traveled at speeds up to 692,000 kilometers per hour during the mission.
帕克太阳探测器据信在任务期间以高达每小时69.2万公里的速度飞行。
NASA said this was “faster than any human-made object has ever moved.”
美国国家航空航天局称，这“比任何人造物体曾经达到的速度都要快”。
Fox said she hopes data collected by the spacecraft can help scientists better understand how the sun behaves and influences other elements in our solar system and beyond.
福克斯表示，她希望航天器收集的数据能帮助科学家更好地理解太阳的行为方式，以及它如何影响太阳系内外其他元素。
“By studying the sun up-close, we can better understand its impacts throughout our solar system, including on the technology we use daily on Earth and in space.”
通过近距离研究太阳，我们可以更好地了解它对整个太阳系的影响，包括对我们在日常地球生活和太空中使用的技术的影响。
Fox added that such studies can provide valuable information “about the workings of stars across the universe to aid in our search for habitable worlds beyond our home planet.”
福克斯补充说，这类研究可以提供宝贵信息，“帮助我们了解宇宙中恒星的运作方式，从而助力我们寻找太阳系外的宜居世界。”
NASA’s statement noted the agency’s earlier preparation and operations were all leading up to the latest mission.
美国宇航局的声明指出，该机构早前的准备工作和运营都是为了最近这次任务做准备。
To help it get into the right position, the Parker Solar Probe received assistance from several flybys of the planet Venus.
为了帮助它进入正确的位置，帕克太阳探测器借助了多次飞掠金星的助力。
The last flyby happened on November 6, 2024.
最近一次飞掠发生在2024年11月6日。
These gravitational assists had put the spacecraft “an ideal distance” from the sun every three months, NASA explained.
NASA解释说，这些引力助推使得航天器每三个月就能与太阳保持“理想距离”。
This distance was “close enough to study our sun’s mysterious processes,” but not “to become overwhelmed by the sun’s heat and damaging radiation.”
这个距离“近到足以研究太阳的神秘过程”，但又不会“因太阳的高温和有害辐射而不堪重负”。
Developers of the spacecraft say it was built with a shield made with carbon material to protect it from the extreme heat released by the sun’s corona.
航天器的研发者表示，它配备了一个由碳材料制成的防护罩，以保护其免受太阳日冕释放的极端高温影响。
The shield was designed to survive temperatures reaching 1,400 degrees Celsius.
该防护罩的设计能够承受高达1400摄氏度的高温。
NASA says the data-gathering instruments are placed behind the shield.
美国国家航空航天局表示，数据收集仪器被安置在防护盾后面。
Nour Rawafi is the project scientist for Parker Solar Probe at NASA’s Johns Hopkins Applied Physics Laboratory in Maryland.
努尔·拉瓦菲是位于马里兰州的美国宇航局约翰斯·霍普金斯应用物理实验室的帕克太阳探测器项目科学家。
His team designed, built, and operates the spacecraft.
他的团队设计、建造并运营了这艘宇宙飞船。
He said Parker had performed as planned although it operates in “one of the most extreme environments in space.”
他说，帕克按计划完成了任务，尽管它运行在“太空中最极端的环境之一”中。
Rawafi added that the mission had brought “a new golden era of space exploration, bringing us closer than ever to unlocking the sun’s deepest and most enduring mysteries.”
拉瓦菲补充说，这次任务开启了“太空探索的新黄金时代，使我们比以往任何时候都更接近于揭开太阳最深奥、最持久的谜团。”
Dr. Joseph Westlake is director of NASA’s Heliophysics Division, the part of the agency that studies the sun.
约瑟夫·韦斯特莱克博士是美国宇航局太阳物理学部门的主任，该部门负责研究太阳。
Westlake noted that his team is preparing for more flybys in the future and hopes to capture more valuable data.
韦斯特莱克指出，他的团队正在为未来的更多飞掠做准备，并希望能捕获更多宝贵数据。
Already, flybys of Venus have gathered information about the natural radio waves coming from Venus.
金星的飞掠已经收集到了来自金星的自然无线电波的信息。
In 2023, scientists announced they had learned new information about solar wind from data collected by Parker.
2023年，科学家宣布，他们从帕克收集的数据中了解到了有关太阳风的新信息。
Data showed that solar wind can reach speeds up to 1.6 million kilometers per hour.
数据显示，太阳风的速度可达每小时160万公里。
Solar wind forms a large magnetic barrier known as the heliosphere.
太阳风形成了一个被称为日球层的大型磁屏障。
It protects Earth and other planets from the continuous flow of high-energy particles from the sun’s corona.
它保护地球和其他行星免受来自太阳日冕的高能粒子持续流的侵袭。
