NASA Responds to Viral 'UFO' Video(翻译)

People on social media have been accusing the American space agency, NASA, of shutting off its live video from the International Space Station. They claim NASA turned off the video stream last week because it showed images of a UFO -- an unidentified flying object.
最近，网友们齐声指责美国国家航空航天局（NASA）在太空直播过程中，突然切掉信号一事。据悉，上周一架疑似UFO的不明物体突然闯入直播画面，NASA随即切断了画面信号。

The video was filmed July 9. A YouTube user named Streepcap1 posted a short part of the International Space Station video. The one-minute 40-second video shows a bright object coming into view. Shortly after the object appears, the video stream experienced technical problems and shut down.
视频拍摄日期为7月9日。Youtube用户Streepcap1上传了一段截取的国际空间站直播视频。在时长1分40秒画面中，一个明亮的不明物体突然闯入镜头。不明物体出现没多久，直播画面就因技术问题被切断。

Streetcap1 wrote, “This could well be a meteor or the like. What made it interesting was the camera cut off when the UFO seemed to stop.”

Streetcap1's video has been viewed more than 2.7 million times. It quickly became a trending topic on Twitter and Facebook.
该视频的浏览量已高达270万次。并且该视频在推特和脸书上迅速走红。

A few days later, NASA answered the questions and theories offered online by people who call themselves “UFO hunters.”
几天后，NAS就“UFO猎人”们在网上提出的质疑及相关理论进行解答。

NASA spokesman Daniel Huot told the technology magazine CNET that the station "regularly passes out of range,” which causes to video signal to disappear.
NASA发言人丹尼尔·霍特（Daniel Huot）告诉《科技资讯网》：一般情况下，只要超出空间站追踪范围，视频信号就会中断。

He also said that the video was part of the agency’s High Definition Earth Viewing experiment. The project includes many different cameras. They are on “automatic controls to cycle through the various cameras,” he said.
霍特还指出，这一明亮的不明物体可能是月亮，可能是太空垃圾，也有可能是太空站玻璃的反光。
