The Queen, the Queen. [qh]
王后，王后。[qh]
Now, Hera was originally supposed to arrive about the same time as DART at Dimorphos at Didymos. [qh]
赫拉本該與DART航天器同一時間到達“迪莫弗斯”與“迪迪莫斯”。[qh]
But instead, due to delays, it is now not launching until late next year, it's going to arrive sometime in 2026. [qh]
但是，由于延誤，赫拉現在要到明年晚些時候才能發射，將于2026年某個時候到達目的地。[qh]
But that's still going to tell us a whole lot more about the aftermath of this epochal impact. [qh]
但這仍將向我們展示更多關于這次劃時代影響的后果。[qh]
Now, there are other things to mention as well. [qh]
現在，還有其他要提的事情。[qh]
One project I'm excited about is NASA's NEO surveyor, the Near Earth Objects Surveyor Space Telescope. [qh]
令我興奮的一個項目是美國宇航局的NEO勘測器，即近地天體勘測空間望遠鏡。[qh]
That is an infrared space telescope that's meant to launch maybe sometime in 2028. [qh]
這是一個計劃在2028年某個時候發射的紅外太空望遠鏡。[qh]
And it will be a very big step towards creating this catalog of objects, and getting a better sense of what's really out there and what the threats are. [qh]
這將是創建天體目錄、更好地識別外太空有什么天體以及存在什么威脅的重大一步。[qh]
And on the ground there’s something similar to the Vera C. Rubin Observatory. [qh]
地面上的NEO勘測器類似于薇拉·魯賓天文臺。[qh]
One thing that's very important for this mission is it will be doing the same kind of work from the ground.[qh]
這項任務非常重要的一點是，NEO勘測器將在地面上完成同樣的工作。[qh]
It will be taking these full, panoramic, high resolution images of the sky multiple times per night, each and every night making almost a high definition movie of the heavens above. [qh]
NEO勘測器將在每晚拍攝數次完整的、全景式的、高分辨率的天空圖像，每晚幾乎都能拍攝出高清的太空圖像。[qh]
And it'll be able to see little points of light moving around, some of which could be Earth threatening asteroids. [qh]
NEO勘測器能捕捉到四處移動的小光點，其中一些可能是威脅地球的小行星。[qh]
Oh, and then that's named after Vera Rubin, right. [qh]
那是以薇拉·魯賓的名字命名的。[qh]
Indeed. One of the discoverers of dark matter, I believe, right? [qh]
確實是。薇拉·魯賓是暗物質的發現者之一，對吧?[qh]
Yes, yes. We also know that researchers with the help of amateur astronomers are continuing to comb through the DART data to find out more about the physics, geology and chemistry of these two asteroids. [qh]
是的。我們也知道，在業余天文學家的幫助下，為找出更多關于這兩顆小行星的物理、地質和化學方面的信息，研究人員仍在持續梳理DART(航天器)的數據。[qh]
Lee, what are you looking forward to the most to finding out in the near future?[qh]
李，你最期待在不久的將來有什么發現?[qh]
Well, honestly, I kind of considered Didymos and Dimorphos a little done and dusted. [qh]
說實話，我覺得“迪迪莫斯”和“迪莫弗斯”的工作徹底告一段落了。[qh]
We’ve already smacked the space rock, we've seen what's happened. [qh]
我們已經成功撞擊了太空巖石，觀察到了相關情況。[qh]
I'm interested in getting this catalogue. I'm interested in knowing more about the properties of a wide diversity of asteroids, because it may not be a rubble pile that comes at us every time. [qh]
我對這份星表很感興趣。我對詳細了解各種各樣的小行星的特性很感興趣，因為不是每次都有一堆碎石會向我們襲來。[qh]
What if it's a big ball of metal? What if it's made of ice? I don't know. [qh]
如果它是個巨大的金屬球體呢? 如果它由冰組成呢? 我不知道。[qh]
That’s true. [qh]
的確是這樣。[qh]
So clearly, the answer is to just smack more cows into pyramids, to send out more of these sorts of missions and get a sense of what happens when we whack things really hard in the solar system.[qh]
很明顯，答案就是把更多的牛撞進金字塔，發送更多這樣的任務，了解當我們在太陽系中猛烈撞擊天體時會是什么情況。[qh]
That said, I have to say, I don't think this is going to be enough to save us. [qh]
盡管如此，我不得不說，我認為這不足以拯救我們。[qh]
There's a lot of situations where something could still hit us real hard and fast and DART definitely wouldn’t save us. [qh]
仍會有很多天體又快又猛襲擊我們的情況，而DART航天器絕對救不了我們。[qh]
I will definitely rest easy. [qh]
我一定會高枕無憂。[qh]
I hope you do. [qh]
我希望你可以。[qh]
Thanks for listening to Science, Quickly. I'm Tulika Bose.[qh]
感謝收聽《科學快訊》。我是圖利卡·博斯。[qh]
And I'm Lee Billings.[qh]
我是李·比林斯。[qh]
