    嘿!大家好,歡迎來到 Life Noggin!

  • 65 million years ago, an asteroid about 10 kilometers wide struck the surface of the

    6 千 5 百萬年前,一顆直徑 10 公里的小行星撞擊地球表面

  • Earth and killed off the dinosaurs.

  • There's actually a chance that an asteroid called Bennu that's about 500 meters in

    事實上這是有可能的,有一顆小行星,Bennu,直徑大約 500 公尺

  • diameter will strike Earth in about 200 years, which is pretty soon when you think about it.

    大約 200 年內可能會撞擊地球,仔細想想其實很快就到了

  • Sure, it's only a one in 2,700 chance, but scientists are beginning to prepare for the worst.

    當然,這只是 1/2700 的機率,但科學家已經開始準備應對最糟的情況

  • Bennu is one of many potential threats in our solar system.

    Bennu 小行星只是我們太陽系中眾多潛在威脅之一

  • There are about 15,000 Near Earth Asteroids catalogued by NASA and while the chance of

    美國太空總署編入了大約 15,000 個近地小行星

  • any of them hitting is small, NASA's Office of Planetary Defense has 3 pretty viable options

    雖然它們撞擊地球的可能性都很低,美國太空總署的行星防禦辦公室還是盡其所能擬定 3 個可行的選擇

  • in their tool belt to protect us.

    來保護我們

  • The first is the Gravity Tractor approach.

    第一個是引力牽引方案

  • A spacecraft would fly up to an asteroid and set up shop right beside it.

    一艘太空船將會飛到小行星旁並一直跟著它

  • After a few years, the presence of a nearby object would alter the gravity of the asteroid,

    幾年過後,鄰近物體的存在將會改變小行星的引力

  • shifting it's trajectory, and rerouting it away from Earth!

    改變它的軌道,並使它遠離地球!

  • We wouldn't even need to touch it.

    我們甚至不需要碰到它

  • Another idea is a bit moreviolent than the Gravity Tractor method.

    另一個主意比引力牽引法還要…激烈點

  • Enter the Hyper-velocity Asteroid Mitigation Mission for Emergency Response, or HAMMER.

    輸入,極速小行星緩解任務應急反應器,或是「錘子 (HAMMER)」

  • Is there, like, a committee of cool people who chooses these names?

    是不是有一個由超酷的人們組成的委員會來選擇這些名字?

  • The idea is that we'd launch a spacecraft equipped with its very own nuclear weapon.

    這個想法是,我們發射一艘裝備核武的太空船

  • If a big asteroid starts to approach Earth, we'd be able to detonate the nuclear warhead,

    如果一顆大型小行星接近地球,我們就能引爆核彈頭

  • blowing off a chunk of the asteroids surface, changing its direction to save Earth!

    吹走一大塊小行星表面,改變它的行進方向來拯救地球!

  • The last is the Kinetic Impactor technique.

    最後一個是動力衝擊技術

  • This seems to be the most straight forward plan and would only require us to nudge an

    這似乎是最直接的方法,我們只需要以正確的方法輕輕推一下

  • asteroid in just the right way to shift its path.

    小行星,改變它的路徑

  • It's so simple and thankfully, we were already able to do this on a small scale with a comet in 2005.

    這相當簡單,謝天謝地我們在西元 2005 年已經能在彗星上達到一些成效

  • And that is definitely promising, but a comet is actually quite different than an asteroid.

    那絕對是非常有希望的,但彗星與小行星事實上還是有很大的差異

  • Asteroids are made up of rocks and metals, while comets are more ice, gas, dust and rock.

    小行星是由岩石與金屬組成,彗星則含有更多冰、氣體、塵埃與岩石

  • The size of asteroids range from just 2 meters to 1,000 km!

    小行星的大小從 2 公尺到 1,000 公里!

  • Comets are typically less than 10 km wide.

    彗星基本上小於 10 公里寬

  • Both objects orbit the sun, but comets are further out.

    兩種物體都繞著太陽運行,但彗星更遠一點

  • They often have tails behind them because as they orbit closer to the sun, the ice and

    兩者通常都會帶著尾巴,因為當它們運行得靠近太陽一些時,組成物體的冰與塵埃

  • dust they're made of begin to vaporize, creating that trail we can sometimes see from Earth.

    會開始蒸發,形成我們偶爾能在地球看到的尾巴

  • Another type of space object we see down here are meteors.

    另一種我們在地球上能看到的太空物體就是流星

  • When a small part of an asteroid breaks off after a collision and is vaporized in Earth's

    當小行星的一部分在碰撞後分離出來,並在地球的大氣層中汽化

  • atmosphere, streaks of light appear in the sky.

    條紋狀的光線就會出現在天空

  • This is what people often mistake for shooting stars, but it's purely part of an asteroid

    這就是人們常誤解的流星,但純粹只是小行星的一部分

  • burning up above us.

    在我們的上空燃燒

  • How beautiful!

    多美啊!

  • There's always a lot of space activity going on around our beautiful planet, and most of

    在我們的美麗星球周邊總是有許多太空活動正在進行,且大多時候

  • the time, it's harmless, but threats do exist.

    它是無害的,但威脅也確實存在

  • Before we can protect ourselves, we need to know the threats are there.

    在我們能保護自己之前,我們需要知道威脅所在

  • The International Asteroid Warning Network is dedicated to finding, following and analyzing

    國際小行星警報網致力於發現、追蹤與分析

  • Near Earth asteroids and just last year, a group of astronomers successfully carried

    近地小行星,就在去年,一群天文學家成功進行

  • out the first international asteroid tracking exercise and it went really well.

    第一次國際小行星追蹤演習,並且進展順利

  • Once we know about any dangerous asteroids, space agencies can decide how to respond in

    一旦我們知道任何有危害的小行星,太空機構就能決定如何回應
