Lift off together as we get off the ground with a story about flight.

一起升空，我們用一個關於飛行的故事，讓我們一起起飛。

Right now, NASA has several active missions to Mars orbiting the planet, observing the planet roving the planet.

眼下，美國宇航局有幾個活躍的火星軌道任務，觀察火星漫遊地球。

The most recent arrival is the $27 billion perseverance mission.

It's got a drone helicopter on board that's carrying a piece of human history.

機上有一架無人駕駛直升機，載著一段人類歷史。

It's about 2.5 ft tall, weighs £4 and cost $23 million to develop its not carrying any scientific instruments.

它高約2.5英尺，重4英鎊，花費2300萬美元開發其不攜帶任何科學儀器。

Ingenuity is purpose is to see if powered helicopter flight is possible on the Red Planet, and NASA says it won't do that until at least April 8th because the chopper has to undergo a series of tests before it can try to lift off.

Ingenuity的目的是看看動力直升機是否可以在紅色星球上飛行，NASA表示至少要到4月8日才能做到這一點，因為直升機在嘗試升空之前要經過一系列測試。

If that works, though, besides making history, the drone is also carrying it.

如果能成功，不過，除了創造歷史，無人機還帶。

It's got a tiny piece of the Wright Flyer aboard.

船上有一小塊萊特飛行器的碎片。

This is the first powered and controlled airplane that people ever built in 19 oh three Orville and Wilbur Wright flew four separate flights on Flyer one near Kitty Hawk, North Carolina.

這是人們在19哦3年建造的第一架有動力和控制的飛機，奧維爾和威爾伯-賴特在北卡羅來納州小鷹市附近的Flyer one上分別飛了四次。

In contrast to the small ingenuity drone, the Wright Flyer had a wingspan of more than 40 ft and a length of more than 21 ft.

與小型獨創性無人機相比，萊特飛行器的翼展超過40英尺，長度超過21英尺。

It was built from wood, canvas, aluminum, steel and iron, and it weighed £605.

它由木頭、帆布、鋁、鋼和鐵建成，重達605英鎊。

As a sort of tribute to that flight, scientists took a bit of fabric that covered the Wright Flyers wings, a small piece the size of a postage stamp, and attached it to a cable underneath the ingenuity drones.

作為對那次飛行的一種紀念，科學家們拿了一點覆蓋萊特飛翔器翅膀的布料，一小塊郵票大小的布料，並將其連接到獨創性無人機下方的電纜上。

It's not the first time NASA has done this for a space flight.

這已經不是NASA第一次為太空飛行做這樣的事了。

In 1969 a piece of the Wright Flyers wing fabric and a splinter of wood from the historic aircraft was traveling aboard the Apollo 11 mission when it flew to the moon and back back on solid but sudden ground.

1969年，賴特飛行器的一塊機翼布料和歷史悠久的飛機上的一塊木頭碎片在阿波羅11號任務中飛行，當它飛到月球時，又在堅實但突然的地面上返回。

Many people in the eastern Australian state of New South Wales are looking forward to a partly cloudy weekend forecast.

在澳洲東部的新南威爾士州，很多人都期待著週末的部分多雲天氣預報。

The weather systems that brought tremendous rain and record breaking floods to the state have moved into the Tasman Sea, but the threat hasn't gone away for some communities as the high waters continue to flow through river systems and keep certain areas flooded for the time being.

給該州帶來巨大降雨和破紀錄洪水的天氣系統已經進入塔斯曼海，但對一些社區來說，威脅並沒有消失，因為高水繼續流經河流系統，使某些地區暫時被淹。

Australia is no stranger to severe weather, but this week's flooding sent spiders scurrying into homes, snakes slithering in the trees and waterfalls emerging in historic and dry landscapes.

澳洲對惡劣的天氣並不陌生，但本週的洪水讓蜘蛛竄入民宅，蛇在樹上溜達，瀑布出現在歷史悠久且乾燥的景觀中。

Hey, Carl, this is one of my favorite parts of the week, getting to research some of the most beautiful and interesting places around the world to take you and our friends here at CNN 10.

嘿，卡爾，這是我這周最喜歡的部分之一，得到研究一些最美麗的和有趣的地方，世界各地，以採取你和我們的朋友在這裡的CNN 10。

So for today's virtual field trip, I am taking you all the way to the land, down under to the spiritual center of Australia.

所以，今天的虛擬實地考察，我將帶大家一路走來，來到這片土地上，來到澳洲的精神中心。

It's known around the world for its ever changing red hues against the backdrop of Australia's central desert, a desert which is usually extremely dry.

But this week, after heavy rains poured throughout northern Australia for nearly a week, this incredible and rare footage emerged of waterfalls at Uluru.

但本週，在整個澳洲北部近一週的大雨傾盆之後，烏魯魯的瀑布出現了這個不可思議的罕見鏡頭。

Stacy McGregor, who works for a local tour company, posted these images to her Facebook and told CNN that she's lived and worked in Uluru for over four years, and she's never seen waterfalls or rain like this.

在當地一家旅遊公司工作的史黛西-麥格雷戈將這些圖片發佈到她的Facebook上，並告訴CNN，她在烏魯魯生活和工作了四年多，她從未見過這樣的瀑布和雨水。

The area typically receives around 13 inches of rainfall in an average year, but recorded nearly two inches on Sunday and Monday of this week alone, according to the Australian Bureau of Meteorology.

根據澳洲氣象局的數據，該地區平均每年的降雨量通常在13英寸左右，但僅在本週的週日和週一就錄得近兩英寸的降雨量。

烏魯魯是聯合國教科文組織世界文化遺產之一。

For decades, people around the globe would come here to climb this incredible natural structure.

Weather here is punishingly hot, and the landscape is often quite windy and slippery.

這裡的天氣是懲罰性的炎熱，而且這裡的風景往往是相當的風滑。

At least 35 people have died here since climbing started in the 19 fifties, but only a lucky few people have been able to visit Hillary recently as tourists have been prohibited from actually climbing the cigarette site since 2019.

自1950年代開始攀登以來，至少有35人死在這裡，但最近只有少數幸運兒能到希拉里參觀，因為自2019年以來，遊客被禁止真正攀登香菸遺址。

The Nanbu Aboriginal people, part of the native population of Australia, said it was being destroyed by tourists permanently wearing down its surface and polluting nearby water holes.

南部原住民是澳洲原住民的一部分，他們說，它被遊客永久地磨損了它的表面，並汙染了附近的水洞。

Here's to hoping the glory of Uluru will be preserved for generations to come back to you, Carl 12th Trivia.

在此希望烏魯魯的榮耀能世代保存，回到你的身邊，卡爾第12屆瑣事。

According to the United Nations, 31% of the Earth's land area is covered by what forests, deserts, lakes or ice.

Deforestation and reforestation Our next Today, the major cause of forest reduction in South America is the intentional clearing of land.

毀林和再造林 我們的下一個目標 今天，南美洲森林減少的主要原因是有意清理土地。

This can be done for wood to expand cities or road projects or to develop more farmland.

這可以是為了擴建城市或道路工程的木材，也可以是為了開發更多的農田。

The Atlantic forest, which runs from northeast Brazil down the country's east coast into Paraguay and Argentina, covers only a fraction of the land that once had.

大西洋森林從巴西東北部沿國家東海岸進入巴拉圭和阿根廷，它只覆蓋了曾經擁有的一小部分土地。

What I really love about being in the forest is seeing the size of the change we can really make.

我真正喜歡的是在森林裡看到我們真正能改變的大小。

Is it really possible to bring out the forest back?

Lori Cullen has dedicated his life to restoring the Atlantic Forest in Brazil after witnessing the destruction of his birthplace, the Western Sanpaolo Atlantic Forest Range used to be a very green, continuous, beautiful landscape.

洛裡-庫倫在目睹了自己的出生地被破壞後，將自己的一生都奉獻給了恢復巴西的大西洋森林，西聖保羅大西洋森林山脈曾經是一片非常綠色、連續、美麗的風景。

What used to be 100% of forest cover now is only 2%.

過去森林覆蓋率為100%，現在只有2%。

Decades of deforestation have led to a significant reduction of one of the world's most diverse habitats.

數十年的森林砍伐導致世界上最多樣化的生境之一大幅減少。

All that remains of the forest are isolated fragments.

森林裡剩下的都是一些孤立的碎片。

This means many species are now under threat as they no longer have the ability to disperse the wildlife, especially Jaguars, Pumas ocelots.

這意味著很多物種現在都受到了威脅，因為它們不再有能力驅散野生動物，尤其是美洲虎、美洲獅鴕鳥。

They are very isolated in small forest patches.

That's when we started having problems of inbreeding, depression that can kill the local population In a very short term, Mm.

這時我們開始有近親繁殖的問題， 抑鬱症可以殺死當地的人口 在一個非常短的時間內，嗯。

Cullen and his team use a targeted approach to forest restoration, taking what's left of the fragments and planting in corridors.

庫倫和他的團隊採用有針對性的方法進行森林恢復，把剩下的碎片，在走廊裡種植。

These proposed corridors aim to connect the fragments and act almost like an express highway for local species to dream of.

這些擬議的走廊旨在將這些碎片連接起來，幾乎就像當地物種夢想的快速公路。

He's putting priorities where where the forest should really be to make sure we put the right corridors in the right places.

他把優先權放在森林真正應該存在的地方，以確保我們把正確的走廊放在正確的地方。

To date, Cullen and his team have restored 3000 Hectors of forest and tell us they have already seen at least half of native species using them, including some animals at most risk of extinction.

到目前為止，卡倫和他的團隊已經恢復了3000個Hectors森林，並告訴我們，他們已經看到至少有一半的在地物種在使用這些森林，包括一些最有可能滅絕的動物。

Today, it's already possible to see the lion tamarins, the families of these little monkey by themselves, using some of the forest quarters that we have put back.

今天，利用我們放回的一些林間宿舍，已經可以看到獅子檉柳，這些小猴子的家人自己。

The survival of this very endangered species will be okay in the long term.

從長遠來看，這個非常瀕危的物種的生存是沒有問題的。

Cullen is motivated by both the community and climate benefits to reforestation, but his accomplishments represent a transformation that is as much personal as it is philanthropic.

卡倫的動力來自於重新造林對社區和氣候的好處，但他的成就代表了一種既是個人又是慈善事業的轉變。

If you give an aspiring engineer enough PVC pipe two by fours, sandbags and cinder blocks, and then you let him work for a few weeks, it's amazing what he can build.

如果你給一個有抱負的工程師足夠的PVC管兩根乘四根，沙袋和煤渣，然後讓他工作幾個星期，他就能造出驚人的東西。

At least it is if he's been to Holiday, a Georgia student who constructed a thrill ride in his backyard.

至少如果他去過Holiday，一個佐治亞州的學生在他的後院建造了一個驚險的遊樂設施。

We don't know how much the materials cost, but we do know it works and that his mother is proud, though she says she's looking forward to getting her yard back.

我們不知道材料的成本是多少，但我們知道它的工作，他的母親很自豪，雖然她說她很期待重新獲得她的院子。

It won't be to her amusement, and she will not find it thrilling if he dips, dives, turns, rolls out and coasts off to college while leaving a construction project on track in her yard, he may ask, Why wouldn't you want it?

如果他在她的院子裡留下一個建築工程的軌道時，在她的院子裡浸泡、俯衝、轉身、滾出、滑行去上大學，她也不會覺得驚險，他可能會問，你為什麼不願意呢？

But if she steeled in her determination not to have her yard marred by a twist adventure, she may not let that train leave the station until the coasters cleared.

但如果她鐵了心不讓自己的院子被一場曲折的冒險所破壞，在雲霄飛車清場之前，她可能不會讓那列火車離開車站。
