美国阿雷西博射电望远镜设备平台坍塌-凯发k8官网

the instrument platform of the 305-meter telescope at arecibo ¹ in puerto rico ² overnight, according to the national science foundation.

美国国家科学基金会称，位于波多黎各的直径达305米的阿雷西博射电望远镜设备平台一夜之间坍塌。

 

据美国有线电视新闻网（cnn）1日报道，nsf当天在推特上说，“阿雷西博射电望远镜的平台一夜之间坍塌，所幸没有人员伤亡报告。”

 

engineers assessed the damage and ³ that all three of the telescope's support towers broke off, sending the 900-ton instrument platform ⁴ down to the dish below. the telescope's support cables also dropped. the observatory's learning center was significantly damaged by the falling cables as well.

工程师们评估并认定了损坏情况：望远镜的三个支撑塔全部断裂，重达900吨的接收平台坠落到下面的碟形反射盘上。此外，望远镜的支撑钢缆也已断裂。望远镜的学习中心也被坠落的电缆严重损坏。

 

据悉，阿雷西博望远镜于1963年建成，口径305米。在“中国天眼”fast2016年9月建成前，阿雷西博望远镜是世界最大的单口径射电望远镜。

 

2017年飓风“玛丽亚”重创波多黎各，造成阿雷西博望远镜钢缆第一次断裂，此后钢缆多次出现断裂。就在11月19日，nsf宣布，该望远镜将被关闭并以可控方式拆除，但相关计划还没实施，就发生了坍塌事故。

 

following two cable breaks in august and november, experts determined that the radio telescope was so ⁵ unsound that it had to be decommissioned.

继8月和11月两次钢缆断裂后，专家们确定，阿雷西博岌岌可危，将面临关闭。

 

长期在阿雷西博天文台工作的物理学家门德斯（abel mendez）告诉美国《商业内幕》（business insider）记者，“当我得知此事时，我完全崩溃了（i was totally devastated）”。

 

"it's hard to take. it's like losing someone important in your life. yeah, 2020 — it's not good."

“我很难接受这个事实，这就像失去了你生命中重要的人。2020年不太走运。”

 

门德斯表示，“现在唯一在做类似研究的地方是中国500米口径球面射电望远镜，它比阿雷西博要灵敏。失去阿雷西博，就失去了一天24小时监控微弱无线电信号的能力，现在我们只有一只眼睛了。”

 

"the only place that we have to do something like that, that'd be sensitive or more sensitive than arecibo, is now fast in china. ...the united states lost all that ⁶ because it doesn't have arecibo."

“中国的500米口径球面射电望远镜（fast）是唯一一个能做类似研究的了，它比阿雷西博更灵敏。……没了阿雷西博，美国就失去了这项本领。”

 

"if you are monitoring a source of interest which is in the weak radio ⁷, you need two big radio telescopes: one pointing toward something during the day, and the other through the nighttime."

“要监控微弱无线电信号，需要两个大型射电望远镜：一个在白天观察，另一个在夜间观察。”

 

"if you lose arecibo, then you lose the ability to monitor — 24 hours a day — a faint source of radio signals. now we just have one eye."

“失去阿雷西博，就失去了一天24小时监控微弱无线电信号的能力。现在我们只有一只眼睛了。”

 

《商业内幕》称，美国失去了其最优秀的小行星和外星人搜寻者（the us has lost its best ⁸ hunter and alien seeker）。
