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. 

美国宇航局表示，一艘一直在检查太阳最外层大气层的航天器最近比任何过去的探测器都更接近我们的地球恒星。 

The American space agency announced its Parker Solar Probe passed within 6.1 million kilometers of the sun’s outer corona on December 24. Mission leaders established communication with the spacecraft after the operation and said the orbiter was safe.

美国航天局宣布帕克太阳探测器于12月24日通过距太阳外日冕610万公里以内的区域。任务负责人在操作后与航天器建立了联系，并表示轨道飞行器是安全的。 

NASA launched the Parker Solar Probe in August 2018. Its mission is to study the sun’s powerful corona and solar wind. Solar wind is created by a continuous flow of charged particles, called plasma, into space from the corona. 

NASA于2018年8月发射了帕克太阳探测器，其任务是研究太阳强大的日冕和太阳风。太阳风是由带电粒子（称为等离子体）从日冕持续流入太空而产生的。 

In 2021, NASA announced the orbiter had passed into the solar atmosphere for the first time. Researchers said at the time, the spacecraft had successfully “touched” the sun. 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. 

2021年，美国宇航局宣布轨道飞行器首次进入太阳大气层。研究人员当时表示，飞船已经成功“接触”太阳。当帕克进入太阳外层大气层时，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. “Flying this close to the sun is a historic moment in humanity’s first mission to a star,” she said. Fox leads the agency’s Science Mission Directorate at NASA Headquarters in Washington, D.C. 

美国宇航局副局长尼基·福克斯在一份声明中赞扬了航天器最近一次经过太阳。“飞得如此接近太阳是人类首次恒星任务的历史性时刻，”她说。福克斯领导位于华盛顿特区的美国宇航局总部的科学任务理事会。 

The Parker Solar Probe is believed to have traveled at speeds up to 692,000 kilometers per hour during the mission. NASA said this was “faster than any human-made object has ever moved.” 

据信帕克太阳探测器在任务期间以高达每小时 692,000 公里的速度行驶。美国宇航局表示，这“比任何人造物体移动的速度都要快”。 

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. “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.” 

福克斯表示，她希望航天器收集的数据能够帮助科学家更好地了解太阳的行为以及对太阳系及其他地区其他元素的影响。“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，包括对我们日常在地球和太空中使用的技术的影响。”
