欧洲发射任务以创建模拟日食
📖 逐句对照翻译
Two European satellites were recently launched on a mission that will include a simulated total solar eclipse.
两颗欧洲卫星最近发射升空，其任务将包括模拟日全食。
The European Space Agency (ESA) launched the satellites on December 5 from southern India aboard an Indian-built rocket.
欧洲空间局于12月5日在印度南部搭载一枚印度制造的火箭发射了这些卫星。
ESA says its Proba-3 mission aims to demonstrate precision formation flying abilities as the two satellites travel together in a fixed position.
欧洲航天局表示，其Proba-3任务旨在展示两颗卫星在固定位置结伴飞行时的精确编队飞行能力。
The two satellites are set to separate and fly 150 meters apart in about a month when they reach their target area high above Earth.
这两颗卫星预计在一个月后抵达地球高空的目标区域时分离，彼此相隔150米飞行。
Creating simulated solar eclipse
创建模拟日食
In one of the mission’s major experiments, the two spacecraft will carry out a series of artificial total solar eclipses.
在该任务的一项主要实验中，两艘航天器将实施一系列人造日全食。
A shadow created by one satellite will permit the other to observe sun activity while blocking out the sun itself.
一颗卫星投下的阴影将使另一颗卫星能够观测太阳活动，同时遮挡住太阳本身。
The goal of this operation is to give scientists the chance to study the sun’s outermost atmosphere, known as the corona.
这次行动的目标是让科学家有机会研究太阳的最外层大气，即日冕。
The corona is difficult to observe because of the brightness of the sun.
日冕很难观测，因为太阳太亮了。
Scientists have repeatedly tried to study this part of the sun from observations on Earth during real total solar eclipses.
科学家们曾多次尝试在日全食期间从地球上观测太阳的这一部分。
But those eclipses do not happen often and usually only last up to five minutes.
但这些日食并不常见，通常只持续五分钟。
The Proba-3 team plans to carry out total eclipses at least twice a week, with each lasting up to six hours.
Proba-3团队计划每周至少进行两次日全食观测，每次持续长达六小时。
Scientists say repeated studies of the corona can help provide new information about how solar activity influences Earth.
科学家表示，对日冕的反复研究有助于提供关于太阳活动如何影响地球的新信息。
For example, the project could help scientists better understand why the corona is so much hotter than the sun itself, and how the sun's energy output changes over time.
例如，该项目可以帮助科学家更好地理解为什么日冕比太阳本身热得多，以及太阳的能量输出如何随时间变化。
Sometimes, intense solar activity can result in geomagnetic storms, which can cause difficulties for power and communication systems on Earth.
有时，强烈的太阳活动会引发地磁风暴，进而给地球上的电力和通信系统造成困难。
"For six hours at a time, it will be able to see the sun's faint atmosphere, the corona, in the hard-to-observe region between the sun's edge and 1.4 million kilometers from its surface," ESA said in a pre-launch statement.
欧空局在发射前的一份声明中说：“它每次能够用6小时的时间观测太阳的微弱大气——日冕，这一区域位于太阳边缘和距其表面140万公里之间，很难观测到。”
Mission leaders say the eclipse experiments will require extreme precision – within just one millimeter – to effectively position the spacecraft.
任务负责人表示，日食实验将要求达到极高的精确度——误差需控制在仅一毫米之内——以便有效定位航天器。
To keep their position, the satellites will depend on GPS, laser systems and radio links.
为了保持位置，卫星将依赖GPS、激光系统和无线电链路。
ESA said in a statement, “Proba-3 is very different because our satellites will be flying just one-and-a-half football fields away from each other during active formation flying.”
欧空局在一份声明中表示：“Proba-3非常不同，因为在主动编队飞行期间，我们的卫星彼此之间的距离仅为1.5个足球场。”
Esther Bastida Pertegaz is a systems engineer on the Proba-3 mission.
埃斯特·巴斯蒂达·佩尔特加斯是Proba-3任务的系统工程师。
She said in a video, "The corona of the sun ... has been very poorly investigated. One of the things we really want to understand is ... how do coronal mass ejections or solar wind originate in this area."
她在一段视频中说：“太阳的日冕……一直研究得很不充分。我们真正想弄明白的一件事是……日冕物质抛射或太阳风是如何在这一区域产生的。”
The $210 million project is being supported by over 40 European companies, Reuters news agency reports.
据路透社报道，这个耗资2.1亿美元的项目得到了40多家欧洲公司的支持。
These include SENER Aerospace, Redwire Space, and Airbus Defence and Space.
这些公司包括SENER航空航天公司、红电线太空公司和空中客车防务与航天公司。
ESA says Proba-3 will aim for at least 1,000 hours of “on demand” totality during its two-year operation.
欧洲航天局表示，Proba-3在为期两年的运行期间，将力争实现至少1000小时的“按需”日全食观测。
Once the mission is complete, both satellites will continually drop lower until they burn up in the atmosphere.
一旦任务完成，两颗卫星将不断降低高度，直至在大气层中烧毁。
Officials said that would likely happen within five years.
官员们表示，这可能在五年内实现。
ESA has said other orbits of Proba-3 – besides the eclipse experiments – will be carried out to demonstrate a range of precise formation flying to help support future missions.
欧洲航天局表示，除了日食实验外，还将执行Proba-3的其他轨道任务，以展示一系列精确编队飞行技术，为未来的任务提供支持。
