珊瑚耶穌，今天在CNN上宣佈了一項重大科學發現。

好吧，也許這是一個有點假的新聞。

但NASA最新的發現之旅並不是去年7月30日發射的漫遊車，原定於昨天抵達火星，科學家們希望這項鍥而不捨的任務能幫助他們弄清楚紅色星球上是否曾經有生命存在。

如果在此期間一切按計劃進行，"鍥而不捨 "號探測器將行駛15英里，研究火星氣候和地質，並收集火星土壤樣本，如果有一天另一項任務成功地派遣航天器來取樣，這些樣本就可以帶回地球。

The rover first had to undergo in extensive check out period, a kind of booting up on Mars.

探測器首先要經歷廣泛的檢查期，也就是在火星上的一種啟動。

It's got to deploy a $23 million drone helicopter whose purpose is to find out if powered chopper flight is possible on Mars, and before any of that could happen, perseverance had to make a safe landing on the Red Planet a preview of a perilous descent on the Red Planet After months traveling through space, it's what NASA describes as seven minutes of terror theme US space agencies.

它得部署一架價值2300萬美元的無人直升機，其目的是找出動力直升機是否有可能在火星上飛行，在這一切發生之前，毅力必須在紅色星球上安全著陸，在紅色星球上危險下降的預覽經過幾個月的太空旅行，這是美國宇航局描述的七分鐘恐怖主題美國航天機構。

Yesterday evening, NASA said that perseverance appeared to land safely on the Red Planet various spacecraft that NASA and the European Space Agency have in orbit.

What is America's coldest city outside of Alaska?

阿拉斯加以外的美國最冷的城市是什麼？

Fargo, North Dakota International Falls, Minnesota or Marquette, Michigan Once you get outside Fairbanks, Alaska, the coldest city in the U.

法戈，北達科他州的國際瀑布，明尼蘇達州或馬奎特，密歇根州 一旦你走出費爾班克斯，阿拉斯加，在美國最寒冷的城市。

A historic blast of Arctic air is finally moving out of the United States after unleashing a Siris of ice and snow storms across the country.

一股歷史性的北極空氣在釋放出全國各地的冰雪風暴Siris後，終於離開了美國。

For those who are ready for winter to end, the good news is that forecasters expect the jet stream toe lift to the north, and what that means is that millions of Americans could feel warmer temperatures by the weekend.

對於那些準備好冬季結束的人來說，好消息是，預報員預計噴氣式氣流將向北抬升，這意味著數以百萬計的美國人可能會在週末前感受到更溫暖的氣溫。

But the hard hit state of Texas is still reeling, with many people still without electricity and or running water following a Siris of deadly winter storms there and mawr.

但重災區德克薩斯州仍然在繅絲，許多人仍然沒有電力和或自來水後，致命的冬季風暴有和毛利的Siris。

Cold, snowy weather could still be ahead for the northern Plains states, the upper Midwest and the Northeast, which is typical this time of year.

There's some fascinating and frozen side effects toe all this.

這一切都有一些令人著迷和冰凍的副作用。

這是CNN 10號特約記者Tyler Molden。

I'm sure you've heard all about blizzards in the polar vortex, Carl, but what about ice pancakes, bites or jams?

我相信你一定聽說過極地漩渦中的暴風雪，卡爾，但冰煎餅，咬傷或果醬呢？

Well, it's a thing, and I'm suddenly hungry, too.

好吧，這是一件事，我突然也餓了。

But these are unappetizing and can cause some real serious issues.

但是這些都是不討好的，會造成一些真正嚴重的問題。

During the winter, an ice jam occurs when pieces of floating ice build up and block the flow of water in rivers and streams and turn, causing the water to back up, potentially leading to flooding.

在冬季，當江河、溪流中的浮冰塊堆積起來，阻擋了水流，併發生轉動，導致水流倒灌，有可能導致洪澇災害。

For example, earlier this month, the National Weather Service in Detroit had an issue of flood warning because an ice jam was causing water to flood homes and businesses, which could only be broken up by the Canadian and US coastguards.

例如，本月初，底特律國家氣象局曾發佈洪水預警，原因是冰塞導致水淹沒了房屋和企業，只能由加拿大和美國海岸警衛隊來破除。

Ice pancakes tend to only be seen in the Arctic, but when the temperature drops below zero in the lower 48 for a few days, like what we're dealing with this week.

冰餅往往只在北極地區出現，但當氣溫下降到零度以下時，在48度以下的地區會出現幾天，就像我們本週要面對的情況。

It occurs when a body of water starts to form ice.

Chunks of ice will bump against each other, creating elliptical shaped dis with round edges, giving each one a flat round appearance.

冰塊之間會相互碰撞，形成橢圓形的圓邊盤，使每個冰塊都呈現出扁圓形的外觀。

You can actually see these every winter near shorelines of colder climates.

其實每年冬天在氣候寒冷的海岸線附近都能看到這些。

These formed by getting caught in the crashing waves near the edge of a beach, forcing them to continually spend over and over and over leading to um, or spherical look.

這些形成的陷入在崩潰的波浪中靠近海灘的邊緣，迫使他們不斷地花費超過和超過導致嗯，或球形的外觀。

Lastly, and this one is probably my favorite ice volcanoes.

最後，而這個可能是我最喜歡的冰火山。

Ice volcanoes form over legs by waves, forcing water or slush to erupt high in the sky through mounds of ice.

冰火山通過波浪在腿上形成，迫使水或泥漿通過冰堆在高空噴發。

It made for quite the scene last year off of Lake Michigan, while we're on the subject of volcanoes but talking about the hot kind now, what's probably the world's oldest continuously active volcano erupted this week.

去年在密歇根湖附近的火山爆發時，我們正在討論火山問題，但現在討論的是熱火山，本週可能是世界上最古老的持續活躍的火山爆發了。

Mount Etna once again put on a fireworks show in the Italian island of Sicily.

埃特納山再次在意大利西西里島上演了一場煙花秀。

Ash rained down on the surrounding region.

There were no reports of serious injuries or damage.

But on the Bismarck High School Boys Swim Team in North Dakota, 12 of the 26 athletes are brothers, as in brothers.

但在北達科他州俾斯麥高中男子游泳隊中，26名運動員中有12名是兄弟，就像兄弟一樣。

Specifically, we're talking about Braxton, Isaac, Austin, Garrett, Bennett, Bryce Jackson, Connor, Josiah, Micah, Blake and Max.

具體來說，我們說的是Braxton，Isaac，Austin，Garrett，Bennett，Bryce Jackson，Connor，Josiah，Micah，Blake和Max。

It's like cheaper by the dozen in the pool and the competitive spirits high because none of these guys wants to lose to his brother.

這就像在游泳池裡一打一打的便宜，競爭精神高漲，因為這些人都不想輸給他的兄弟。

這是否會威脅到他們的兄弟之情？

And while the goggles might have them wondering, O brother, where art thou?

雖然護目鏡可能會讓他們疑惑，兄弟啊，你在哪裡？

They're still there to help each brother bear the brothers, Um, burden of competition, saying, Brother, let me be your shelter.
