Hi, I'm Carla Zeus were blasting off with a couple space stories this December 7th, and we're glad to have you aboard.

嗨，我是卡拉-宙斯... ...在12月7日的時候，我們帶著幾個太空故事離開了，我們很高興你能來。

It's been a little while, and by that I mean decades since a spacecraft tried to pick up some rocks from the moon.

已經有一段時間了，我指的是幾十年前，一艘航天器試圖從月球上撿起一些石頭。

But that's what an unmanned Chinese probe did this week.

但這就是中國無人探測器本週的工作。

And if the mission successfully brings those rocks back to Earth, it'll make China the third country to do this behind the United States and the former Soviet Union.

而如果這次任務成功將這些岩石帶回地球，將使中國成為繼美國和前蘇聯之後第三個這樣做的國家。

Could the lunar samples that China gathers be different than what's already been collective?

中國收集的月球樣本會不會與已經集體的樣本不同？

Possibly the Chinese probe landed in the dark spot of the moon called the Ocean of Storms, and what it picked up could give rise to new theories about Earth's natural satellite.

可能是中國的探測器降落在月球的暗點，叫做風暴海洋，它所發現的東西可能會引起關於地球天然衛星的新理論。

This is quite a scientific and technological feat for the Chinese.

這對中國人來說，是一個相當大的科技壯舉。

This latest mission involved the spacecraft robotic arms, scooping up rocks from the surface of the moon and also having a 2 m long drill retrieving soil samples from underground.

這次最新的任務涉及到航天器的機械臂，從月球表面挖出岩石，還讓一個2米長的鑽頭從地下取回土壤樣本。

And all of these samples have now been packed and sealed in a canister in a part of the spacecraft that will be making its way back to Earth.

而所有這些樣本現在都已經被打包並密封在一個罐子裡，裝在航天器的一部分，將返回地球。

It's expected to land in northern China later this month.

預計將於本月晚些時候在中國北方登陸。

So this is quite an important step forward in this country's ambitious space program, which is now a pillar for its national development under President Xi Jinping.

是以，這對這個國家雄心勃勃的太空計劃來說，是相當重要的一步，它現在是習近平主席上司下的國家發展的支柱。

But one thing that's worth noting is all of these accomplishments so far are things that United States has done in the past, sometimes decades in the past.

但有一點值得注意的是，到目前為止，所有這些成就都是美國在過去，有時是在過去幾十年裡所做的事情。

So what the Chinese have done is they were making their own first by doing things slightly differently.

所以，中國人所做的是他們在做自己的第一件事，做法稍有不同。

For example, this time they landed this probe in the part of the moon.

比如，這次他們將這個探測器降落在月球的部分。

S had not visited in the past, and also they were catching up fast with the U.

斯過去沒有訪問過，而且他們也在快速追趕U。

Because China is a late comer in space explorations.

因為中國是太空探索的後來者。

But just in the past decade they have successfully launched three manned space missions and now, of course, three successful lunar probe missions.

但就在過去的十年裡，他們已經成功發射了三次載人航天任務，當然現在又成功地完成了三次月球探測任務。

Currently, they also having a Mars mission going on there, also about to start building their own full scale space station Now, all of this, of course, has been a source of great pride for the government and the people here.

目前，他們還在那裡進行著火星任務，也即將開始建造自己的全比例空間站 現在，這一切，當然已經讓這裡的政府和人民感到非常的自豪。

But this also has quite a geopolitical dimension, Aziz Well, because NASA is prohibited from cooperating with the Chinese space program due to national concern security considerations.

但這也有相當的地緣政治因素，阿齊茲嗯，因為出於國家關注安全的考慮，NASA被禁止與中國的太空計劃合作。

So, according to many experts, this latest mission is a message from Beijing to the rest of the world that China is increasingly becoming a legitimate alternative to a US led space.

是以，許多專家認為，這次最新的任務是北京向世界其他國家發出的資訊，即中國正日益成為美國主導的太空的合法替代者。

Now a space discovery recently published in the monthly Notices of the Royal Astronomical Society, a research group, says it's identified an exoplanet a planet that orbits around a different star than our sun.

現在，一個太空發現最近發表在英國皇家天文學會月刊《通告》上，一個研究小組說，它確定了一顆系外行星，一顆圍繞著比我們的太陽不同的恆星運行的行星。

Researchers say they identify exoplanets by how much they appear to dim the Starlight when they pass in front of a star we can observe.

研究人員說，他們通過外行星在經過我們可以觀察到的恆星面前時，它們看起來有多暗星光來識別外行星。

Tyler Mauldin Carl Researchers say they have discovered a planet on the very edge of our solar system, and it features some rocky weather.

泰勒-毛爾丁-卡爾研究人員說，他們在太陽系的邊緣發現了一顆行星，它的特點是一些岩石天氣。

This lava planet, named K 2141 B, say that three times fast was discovered in 2018, according to a statement from McGill University.

根據麥吉爾大學的一份聲明，這顆熔岩行星被命名為K 2141 B，說快三倍投計劃是在2018年發現的。

Ah, Lava Planet is a fiery hot world that circles so close to its host star that some regions are likely oceans of molten lava Que 2141 B is also unique because it orbits close enough to its star that the two are gravitationally synchronized.

啊，熔岩行星是一個熾熱的世界，它的運行軌道離它的宿主恆星很近，有些區域很可能是熔岩的海洋闕2141 B也很獨特，因為它的運行軌道離它的恆星很近，兩者的引力是同步的。

This leads to two thirds of the planet having endless amounts of daylight and the other third having perpetual darkness pretty cool.

這就導致地球上三分之二的地方有無窮無盡的日光，而另三分之一的地方則有永久的黑暗，非常酷。

This has major implications for the planet now and in the future.

這對現在和將來的地球都有重大影響。

The dark side experiences temperatures as cold as minus 200 degrees Celsius, while the sunlit side has a temperature of approximately 3000 degrees Celsius.

黑暗面的溫度低至零下200攝氏度，而陽光面的溫度約為3000攝氏度。

Not only is that enough to melt rocks and give way to the lava oceans, but according to a recent study by McGill University, York University and the Indian Institute of Technology, it's hard enough to entirely vaporize rocks.

不僅足以融化岩石，給熔岩海洋讓路，而且根據麥吉爾大學、約克大學和印度理工學院的最新研究，它的硬度足以讓岩石完全汽化。

This creates a vaporizer rock atmosphere on the planet, like the Earth's water cycle.

這就在地球上形成了汽化巖大氣，就像地球的水循環一樣。

These minerals then rain back down as chunks of rock, and the cycle repeats.

然後這些礦物質以岩石塊的形式回落，循環往復。

K 2141 B surface and atmosphere over time.

K 2141 B地表和大氣隨時間推移。

What US state is known as the Beehive State, Washington, North Dakota, Mississippi or Utah.

美國哪個州被稱為蜂巢州，華盛頓州、北達科他州、密西西比州或猶他州。

North Dakota produces the most honey, but it's the 45th ST.

北達科他州生產的蜂蜜最多，但它是第45ST。

A farm in Utah is going vertical and robotic to feed its animals.

猶他州的一個農場正在進行垂直和機器人餵養動物。

Automated towers use light emitting diodes or led lights to help grow fresh animal feed.

自動塔使用發光二極管或led燈來幫助種植新鮮的動物飼料。

The farmers say it takes six days to grow that feed from seeds to harvest, and that the process produces a predictable, optimum crop.

養殖戶說，該飼料從種子到收穫需要6天的時間，這個過程中產生的作物是可以預測的，是最佳的。

Is this the future of farming, or at least farming animal feed their pros and cons to going vertical.

這是未來的養殖業，或者至少是養殖動物飼料他們的優點和缺點去垂直。

It takes up less land area than traditional farming, but it could be expensive to get started.

與傳統農業相比，它佔用的土地面積較少，但起步成本可能很高。

You've gotta have the building and the machines.

Vertical farming uses less water than traditional farming, but it relies on artificial light and a lot of electricity.

垂直農業比傳統農業用水少，但它依靠人工光照和大量電力。

The new technology may not work well for all crops, and critics say farming without natural soil can't be considered organic.

新技術可能無法很好地適用於所有作物，批評者說，沒有天然土壤的耕作不能被視為有機。

But for the vertical farmers in Utah who are concerned about long term weather and the challenges brought on by the coronavirus pandemic, they say this is an efficient solution and that it has a lot of potential moving forward.

但對於猶他州的垂直農民來說，他們擔心長期的天氣和冠狀病毒大流行帶來的挑戰，他們說這是一個有效的解決方案，而且它有很大的前進潛力。

Next, we're sinking to new depths on CNN.

接下來，我們將在CNN上沉入新的深度。

It's because we're diving into what's believed to be the world's deepest swimming pool.

因為我們要潛入據說是世界上最深的游泳池。

It's located in Poland, took more than two years and $10.5 million to build.

它位於波蘭，耗時兩年多，耗資1050萬美元建成。

And if you're wondering why someone might construct something like this, there are several reasons most still Uh huh, yeah.

如果你想知道為什麼有人會構造這樣的東西，有幾個原因，大多數人還是嗯哼，是的。

Ah, not a lot of snow in the forecast for Albuquerque, New Mexico.

新墨西哥州阿爾伯克基的預報中沒有很多雪。

It's in the Chihuahuan Desert, so But that doesn't mean people there don't wanna build a snowman.

這是在奇瓦瓦沙漠，所以... ...但這並不意味著那裡的人不想堆雪人。

And they did, in a manner of speaking, using tumbleweeds.

而他們也確實，在某種程度上，用風滾草。

This is an annual tradition dating back 25 years.

這是一個可以追溯到25年前的年度傳統。

He is wearing a mask this time because 2020 the tumbleweeds are spray painted white and accentuated with recycled materials for the hat and eyes.

他這次戴上了口罩，因為2020年風滾草被噴成白色，帽子和眼睛都用回收材料來強調。

And if that doesn't make you smile, maybe you're a diaspora sport.

如果這不能讓你微笑，也許你是個僑民運動。

Sorry if that causes a dust up, but a tumbleweed snowman is rooted in the Christmas spirit.

如果引起塵埃，對不起，但風鈴草雪人是植根於聖誕精神的。

It give even Scrooge his just deserts and weed out any haters.

它讓史高治也得到了應有的懲罰，並清除了所有的仇敵。

So if you think all tumbleweeds good for is dust in the wind Well, that's the last straw.

所以如果你認為風滾草的好處是風中的塵埃，那就是最後的稻草了。

I want to give a shout out to a school that's got heart.

It's located in the heart Butte, Montana.
