火星的古老卫星？

没错。

That's right.

给你看些JWST的酷炫图像。

Cool JWST images for you.

你再也不会用以前的眼光看太空照片了。

You're never gonna look at a picture of space again.

是啊。

Yeah.

对啊。

Yeah.

那些都不行。

None of that.

或者，比如用GPS。

Or, like, use GPS.

没错。

Right.

是啊。

Yeah.

或者手机之类的任何东西。

Or cell phones or anything.

任何东西。

Anything.

手机摄像头。

Cell phone cameras.

不适合你。

Not for you.

特氟龙不也是特氟龙锅吗？

Teflon weren't Teflon pans?

对。

Yeah.

像是NASA的东西？

Like, a NASA thing?

我想是的。

I think so.

而且你不能想到唐。

And you can't think tang.

没有唐。

No tang.

也没有冻干食品。

No and nothing freeze dried.

哦。

Oh.

没有宇航员冰淇淋吗？

No astronaut ice cream?

飞机的防冰系统、除冰系统呢？

Anti icing systems, de icing systems on airplanes?

不是给你的。

Not for you.

你得下去

You gotta get off

这架飞机

the plane.

是啊

Yeah.

显然这项技术最初是为NASA开发的，后来也能用在飞机上

Apparently, the technology was developed for NASA, then you can use it on airplanes too.

哦，好吧

Oh, okay.

我是说，NASA确实搞飞机

Well, I mean, NASA does airplanes.

所以哦，这就说得通了

So Oh, there you go.

一个

One

其中一个A。

of the a's.

那是。

That is.

很多东西，比如，

A lot of things that, like,

NASA航天局。

NASA space administration.

国家

National

航空与航天。

Airplane and Space.

航空学。

Aeronautics.

是的。

Yeah.

谢谢你的澄清。

Thanks for that thanks for that clarification.

NASA也是。

NASA too.

我很好奇还有其他的吗？

Are there other I'm curious.

比如，有没有什么别的东西，如果你不支持就无法从中受益，那会很有趣？

Like, is there another thing out there that if you don't support, you can't benefit from that would be hilarious?

哦。

Oh.

比如，嗯，我是说支持

Like Well, I mean support

嗯，无线吸尘器

Well, cordless vacuums

你也可以重新打扫你的房子。

You can also your house again.

是啊。

Yeah.

有线无线吸尘器是NASA的一个衍生项目。

Cord cordless vacuums was a NASA offshoot type of situation.

没错。

Yeah.

因为他们不想在航天飞机里拖着电线到处走。

Because they didn't wanna drag cords around the space shuttle.

纯属猜测。

Just guessing.

对。

Yeah.

我本来会从更广义的角度来理解这个问题。

I was I would have taken this much more generally like this.

我也经常这么说。

I I always say that too.

比如，如果你认为地球是平的，那你就不该使用任何现代科技产品。

Like like, if you if you think the Earth is flat, you don't get to use anything.

因为本质上，我们整个西方文明都是建立在科学带来的成果之上的。

Because, like, essentially, our entire Western civilization is based on the things that science has given us.

是啊。

Yeah.

同样的科学...你懂的，不。

Same science is well, you know No.

帮帮忙。

Help it.

给

To

去你的。

screw you.

受不了了。

Can't take it.

你不能坐飞机。

You can't take an airplane.

是啊。

Yeah.

你不能，你什么都不能。

You can't take you can't Nothing.

哦，那里

Oh, there

你 是啊。

you Yeah.

什么都不行。

Nothing.

你可以的。

You can yeah.

你可以当个狩猎采集者。

You can be a hunter gatherer.

这样没问题。

That's fine.

就这样吧。

That's it.

你可以在你所在地方圆100英里范围内生活。

You can live within a a 100 mile radius of wherever you are.

有些事情你得，比如，回到我们发现那件事之前的时代。

Certain things you have to, like, go back to the time prior to when we discovered that thing.

没错。

That's right.

是的。

Yes.

对。

Yeah.

基本上是这样。

Basically.

没错。

That's right.

就像那样。

Like that.

你得像那些人一样生活。

You have to live like those people.

就像《星际迷航》那集一样。

Like that Star Trek episode.

就跟那一模一样。

Exactly like that one.

是啊。

Yeah.

那集叫什么来着？

What was that called?

真见鬼。

Darn it.

我们所有的昨日。

All our yesterdays.

没错。

Yep.

那真的是它的名字吗？

That actually what it's called?

那确实就是它的名字。

It is actually what it's called.

得了吧。

Come on.

你认真问我这个问题吗？

Are you serious with me asking you that question right now?

我花了五秒钟才想起来，真尴尬

I'm embarrassed that I it took me five seconds

想起来。是的。

to get Yeah.

到这个

To this

好的。

Okay.

说到NASA和飞机，他们对其静音超音速测试飞行器进行了试飞。

Speaking of NASA and airplanes, they did a test flight of their test vehicle that's a quiet supersonic plane.

听起来有点吵，但据说它不像音爆那么响。

It sounded kind of loud, but it's but it didn't supposedly, it's not a sonic boom loud.

这是ASR版本。

This is the ASR version.

哦，那不错。

Oh, that's nice.

吉姆开始感兴趣了。

Jim is getting into it.

我我是说，是的。

I I meant yeah.

是的。

Yeah.

我们要做这件事。

We're gonna do it.

我们会专门做一个这样的，并单独放在

We'll do a special one of those and put it on a separate

我们之前某个时候讨论过他们正在研发这个。

We had we talked about this at some point previously that they were developing it.

没错。

Yes.

但现在他们已经试飞了。

But now they've flown it.

而且它比音爆安静，更像是亚音速爆鸣。

And it's, like, quieter than a sonic boom, but it's like a subsonic boom.

我不明白你的意思。

I don't understand what you mean.

所以如果你超音速飞行，就必须产生音爆。

So if you go faster than the speed of sound, you have to produce a sonic boom.

音爆产生的分贝数降低了。

It's the decibels that the sonic boom makes are lower.

我想你说的是必须产生冲击波，吉姆。

You have to produce a shock wave, I think, is what you're saying, Jim.

对。

Right.

没错。

Right.

胜过音爆。

Beats a sonic.

正是如此。

That's right.

但通过飞行器合适的几何形状设计，你可以控制冲击波的形态。

And but the but you can shape that shock wave with the appropriate geometry of your vehicle.

哦。

Oh.

这样就会产生不同程度的冲击哦。

And that then results on in a different level of impact Oh.

声学上。

Sonically.

而且我觉得听起来我好像很懂行，对吧？

And and I think it sounds like I know what I'm talking about right here, which is you know?

所以我们该继续下一个话题了。

So we should move on.

听起来你

A It sounds like you

不具备我偶尔拥有的这项技能。

don't A skill I sometimes have.

但无论如何，这是架有趣的飞机。

But in any event, it's an interesting plane.

这不是一架实用的飞机。

It's not a practical plane.

它只是一个测试飞行器。

It's just a test vehicle.

这不是那种短期内会有人乘坐的飞机。

It's not a plane anybody's gonna be taking a ride anytime.

飞行员实际上是盲飞的。

The pilot actually flies blind.

我是说，风...我不确定有没有窗户，但即使有也看不清前方。

There's no I mean, the wind I don't know if there's a window, but the window can't see in front of you.

所以飞行员全靠驾驶舱内的显示器操作。

So it's all monitors inside the inside the pilots.

驾驶舱。

Cockpit.

这是常见的设计吗？

Is that typical?

不是。

No.

这不典型，奥黛丽。

It's not typical, Audrey.

好吧。

Okay.

你问‘这典型吗’是什么意思？

What do you mean is that typical?

就是，

Like,

飞机。

planes.

你没见过飞机和它们的窗户吗？

Haven't you seen airplanes and their windows?

没有。

No.

比如，那些超音速飞机。

For, like, for the for superfast airplanes.

不。

No.

它们有某种视觉装置。

They have some sort of visual.

但是，就像

But, like

大多数超音速飞机都是战斗机。

Most superfast airplanes are fighter jets.

而且所有

And everything

驾驶舱都有窗户。

has cockpits with windows.

是的。

Yeah.

好的。

Okay.

它们能飞...哦，我确实看到了。

And they can fly Oh, I did see it.

我见过那个。

I've seen that.

是的。

Yeah.

说到测试飞行器，星舰基地有一次测试

And speaking of test vehicles, there was a test at Starbase

没错。

Yep.

是SpaceX的超重型火箭。

With, the SpaceX Super Heavy vehicle.

三号。

Three.

第三版本，当时确实出了问题。

Version three, and it did there was a problem.

是的。

Yeah.

所以B2最终取得了巨大成功，因为那是他们最近一次成功发射的飞行。

So b two ended up being highly successful in the end because that was the most recent flight where they were able to launch it.

什么？

What?

二？

Two?

V二。

V two.

哦，第二版本。

Oh, version two.

好的。

Okay.

超级重型火箭的。

Of the Super Heavy.

是的。

Yes.

版本二，不是V二。

Version two, not the v two.

那是筷子回收架吗？

Is that the chopsticks?

那次也非常成功。

It was also very successful.

那次算是中等程度的成功。

It was moderately successful.

什么，奥黛丽？

What, Audrey?

就是那个用筷子回收架的

Is that the chopsticks one that

你接住

you catch

就是那个被筷子夹住的。

That's the one that gets caught by chopsticks.

对。

Right.

明白了。

Got it.

是的。

Yeah.

所以这就像是助推器的下一阶段。

So it's like next phase of the booster.

你准备好了吗？

You ready?

没错。

Right.

但他们目前还只是在进行早期测试，结果出了点小爆炸。

But they're just but they're still just doing, like, early testing on it, and it it had a little explody.

是啊。

Yeah.

他们当时在做压力测试，结果它承受不住压力。

They were doing a pressure test, and it did not it couldn't take the pressure.

公司表示，首次操作将测试助推器重新设计的推进系统及其结构强度。

The first operations will test the booster's redesigned propellant systems and its structural strength, the company said.

显然，结构强度测试失败了。

And apparently, the structural strength failed.

所以它不具备应有的结构强度。

So it did not have the correct structural strength.

结构强度的某些方面还需要改进。

Some element of the structural strength, needs some work.

但要知道，这对整个人类太空飞行计划的时间表来说是个重大挫折，目前整个计划很大程度上依赖于超级重型运载火箭和其上级火箭（即所谓的星舰）的全面运行。

But this is, you know, this is an important setback in the schedule for the whole human spaceflight program is currently sort of mapped out, relies heavily on the Super Heavy launch vehicle and getting their upper stage, the so called Starship, rocket fully operational.

我们已经进行了多次试飞，结果好坏参半。

We've had a bunch of test flights of this with varying degrees of success.

上一次实际上非常成功。

Last one was actually really successful.

是啊。

Yeah.

对吧？

Right?

有意思。

Interesting.

但上级火箭实际上甚至还没有完成完整轨道。

But the upper stage did not actually hasn't even done a full orbit Correct.

绕地球的轨道。

Yet of the Earth.

而它应该要达到能在星际飞船上级火箭之间进行燃料补给的程度，这样才能前往月球。

And that's supposed to get to a point where they can do refueling between those star ship upper stages and the thing supposed to get to the moon.

还有一个版本是计划登月并在月球上着陆的。

And there's a version supposed to get to the moon and land on the moon.

嗯。

Mhmm.

我得想想，是谁写了龟兔赛跑的故事来着？

I'll have a Who was it that wrote about the tortoise and the hare?

伊索。

Aesop.

这个寓言对SpaceX和蓝色起源公司有某种相关性，因为蓝色起源绝对是那只乌龟，没错。

There's a certain relevance of that fable to SpaceX and Blue Origin because Blue Origin, who has definitely been the tortoise Yep.

在这个类比中，他们总共只进行了两次轨道飞行。

In this, analogy, has only done two orbital flights at all.

而SpaceX到现在已经进行了大约9000次左右。

SpaceX has done, like, 9,000 or something by this point.

但他们看起来已经准备好，在接下来发射一个月球着陆器，一个相当大的月球着陆器。

But they're looking primed to send a lunar lander, a pretty pretty big lunar lander within the next

他们应该能做到。

They're supposed to do it.

六到十二个月内登月。

Six to twelve months, to the moon.

所以他们可能...我们拭目以待。

So they may We'll see.

实际上可能会在SpaceX之前用这些着陆器抵达月球表面。

Actually make it to the surface of the moon before SpaceX does with one of these landers.

而且很应景的是，他们传统上会在飞行器上画乌龟图案，因为这正是他们的策略。

So And appropriately too, they've they've traditionally put tortoises on their vehicles because that's their approach.

这就是他们的策略。

That is their approach.

缓慢但凶猛。

Slowly but ferociously.

没错。

Yeah.

是的。

Yep.

所以这真的很可爱。

So That's really cute.

乌龟是很凶猛的。

Turtles are ferocious.

不。

No.

鳄龟吗？

Snapping turtles?

它们确实非常

They are they are absolutely

凶猛。

ferocious.

对。

Yeah.

有些乌龟确实把我吓到过。

There are some there are some turtles that have scared me.

是啊。

Yeah.

没错。

Yeah.

当我试图救它们的时候，在

When I was trying to save them, by the

说到这个，我超爱看佛罗里达人在马路上救乌龟的那些视频。

way Speaking of the there's I love the videos of Floridians saving turtles on the road.

你知道吗，当你看到有人会在马路中间停下来救一只过马路的乌龟，那准是佛罗里达人。

Like, you know a Floridian when you could see them, like, stop in the middle of the road to save a turtle crossing?

对。

Yeah.

确实

True

佛罗里达人

Floridian.

阿什莉·S·阿什莉·基霍和我做过

Ashley s Ashley Kehoe and I did

那一次

that one time.

我做过，但那只乌龟并不领情。

I've done it, and I've and the turtle was not appreciative.

拍下来了。

Snapped.

是啊。

Yeah.

我当时正试着

I was trying

这么做。

to do that.

那只乌龟发疯了。

Turtle went nuts.

你跟它解释了吗？

Did you explain to it?

那是什么情况？

What was that?

你知道吗？

You know?

它完全没料到，一个看起来像石头的东西会突然变成火箭推进的铁饼。

Mean was not prepared for something that basically looks like a rock to all of a sudden become a rocket propelled discus.

天啊。

Oh my god.

这个视频。

This video.

当时真的很吓人。

It was was alarming.

但蓝色起源上次成功发射的任务，我们之前讨论过新格伦火箭，那是它的第二次发射，执行的是Escapade任务。

But the last mission that Blue Origin successfully launched, we talked about it with New Glenn, was its second launch and it launched the escapade mission.

Escapade任务需要一段时间才能抵达火星目的地，但它已经开始传回一些图像。

And the escapade mission is going to take a while to get to Mars where it's going, but it has started sending back some images.

它传回了一些

It sent back some

这些图像是来自那些小...这些一定是如果

Are are those images from the little those must be if

它们是航天器上的。

they're spacecraft.

但我指的是我们北亚利桑那大学的同事安装的那些小摄像头拍摄的

But I mean from the little cameras that our colleagues at Northern Arizona University put on

哦，可能是吧。

Oh, maybe.

是的。

Yeah.

我没看那个。

I didn't look at that.

来自NAU的。

Where from NAU.

我们的前学生泰勒·考克斯

Our former student, Tyler Cox

他现在。

He's now.

在那个团队里。

Is in that team.

哦，他在Escobee团队？

Oh, he's on the Escobee team?

嗯，他在实验室里负责相机工作。

Well, he's working in the lab On the cameras.

由相机项目负责人克里斯·爱德华兹领导。

Run by the PI of the cameras, Chris Edwards.

是啊。

So yeah.

所以我不确定他是否专门研究过那些相机。

So I don't know if he's specifically worked on those cameras.

可见光和红外观测系统或视觉相机。

The visible and infrared observation system or visions cameras.

太棒了。

That's terrific.

他们给自己的太阳能板拍了照片。

They imaged their own, like, solar panels.

太棒了。

Terrific.

向那个团队和北亚利桑那大学的同仁们致敬。

Shout out to that team and the folks at NAU.

太赞了。

Awesome.

我想它会在2027年9月抵达火星。

Think it takes it'll arrive in Mars in September '27.

那基本上就是在火星附近徘徊了。

That's a that it's basically hanging out wonders.

它基本上要在这里待上一年。

It's basically hanging out here for a year.

是的。

Yeah.

明年11月。

In November next year.

对。

Yeah.

他们会再来一次弹弓效应加速。

They do another slingshot.

没错。

Yeah.

所以它只是在地球附近的空间徘徊，直到地球和火星处于合适的位置

So it's just loitering in space along with the Earth until the Earth and Mars are in the appropriate

我非常喜欢这种方式，这是个超级酷的方法

big fan of these like, it's a super cool approach.

我知道我们上次讨论过，但我还要再说一次

I know we talked about it last time, but I'm gonna talk about it again.

这是个超级酷的方法

It's a super cool approach.

有些想法是，比如你可以发射航天器，让它们待命，等需要前往目的地时就能立即出发

There's ideas of, like, you could launch space craft, and then they'll hang out, and then they'll be ready when they need to go where they need to go.

没错

Right.

比如有一些关于彗星拦截器的提案，还有其他航天任务，基本上就是先发射一些飞行器，让它们准备就绪

Like, there's some proposals for comet interceptor, right, and for other spacecraft missions where you basically, like, launch some vehicles, and then they're ready.

需要时就能用上

Use it when you need it.

三号飞船经过或其他情况发生时。

Three I comes by or something else happens.

是啊。

Yeah.

事实上，我看到一个标题提到类似宇航员救援的方案。

And in fact, I saw a headline referring to something along those lines for astronaut rescue.

哦。

Oh.

因为你知道，电影里那些有趣的画面——两架航天飞机同时停在发射台上，然后各种戏剧性情节。

Because But then, you know, there's the fun images that are in the movies where you have two shuttles on a pad at the same time and you have to blah blah blah.

没错。

Yeah.

那部电影不怎么样。

That movie wasn't very good.

公平地说，好几部电影都有这种桥段。

That's in several movies, to be fair.

而且大多数电影在这一点上都有些站不住脚。

And most of them break down a little bit right around there.

对。

Right.

好的。

Okay.

你知道哪部救援电影发射台上只有一架航天飞机吗？

You know which which which rescue movie only had one shuttle on the pad?

没错。

That's right.

犀利观点。

Hot take.

这话绝对靠谱。

Take it to the bank.

还有一大堆其他电影也是。

And also a bunch of other movies.

说到阿特拉斯三号，我

So speaking of Atlas three I

看看我们这话题转得多自然

Look at us with our segues

也是。

too.

我们这话题转换简直出神入化。

We're segueing it out of the park.

哇。

Wow.

我们就像话题转换界的大谷翔平。

We're like Shohei Ohtani of Segways.

很棒的棒球比喻，乔。

Good baseball reference, Joe.

谢谢。

Thank you.

不错。

Nice.

我打赌你没想到会这样。

I bet you weren't expecting that.

确实没想到。

I wasn't.

是啊。

Yeah.

不过这个比喻很棒。

But it was a good one.

我很喜欢。

I loved it.

他挺好的。

He's fine.

所以

So

阿特拉斯三号，当你把东西拉上来时，有一颗星际彗星

Atlas three I to as while you're pulling things up there is an interstellar comet

我听说是这样。

That's what I've heard.

它正穿过太阳系，这可能是它存在大约七十亿年以来第一次如此温暖，因为它与太阳的距离大致相当于火星，或者更近一点。

That is passing through the solar system and is probably the first time ever in its probably or possibly seven billion years of existence that it's ever been as warm as it is now because it's roughly Mars distance from the sun or getting a little bit closer.

而且它

And It's

是航天器物体中的格林奇。

the Grinch of of spacecraft objects.

我们有

We have

前几天有三个尺寸。

three sizes the other day.

是啊。

Yeah.

我们并没有专门发射航天器去观测它，但幸运的是，太阳系里恰好有许多因其他任务而漫游的航天器可以顺便观测它。

We don't have spacecraft that were launched specifically to look at it, but we do serendipitously have a bunch of spacecraft wandering about the solar system for various other purposes that could take a look at it.

是啊。

Yeah.

我们之前讨论过三I号，我记得在这次近距离接近发生时也聊过它。

We talked about three I a while back, and I think we talked about it when this, like, close approach was happening.

但由于NASA当时停摆，他们无法就收集到的任何数据发布新闻稿，而现在他们可以了。

But because NASA was shut down, they couldn't do press releases about any of the data they'd collected, and now they have.

还有其他人想聊聊这个吗？

Does anybody else wanna talk about it?

我可以谈谈这个。

I can talk about it.

你来谈谈吧。

You talk about it.

好的。

Okay.

不。

No.

不？

No?

好吧。

Okay.

所以

So

没人会吝啬给你机会谈谈三I。

Nobody's begrudging you the opportunity to talk about three I.

太好了。

Great.

所以我...我不知道。

So I I don't know.

我觉得这超级酷，因为基本上我们所有的航天器，包括一堆地面设备，还有那些本来在观测其他东西的航天器，都有机会给它拍张照片。

I think this is super cool because, basically, like, all of our spacecraft, a bunch of ground based assets, but also a bunch of spacecraft that we have looking at other things got a chance to, like, snap a photo of it.

这其中就包括了MAVEN探测器。

And so that included MAVEN.

它正在环绕火星运行。

Which is orbiting Mars.

它正在环绕火星运行。

Which is orbiting Mars.

还包括火星表面的设备。

It included things on the surface of Mars.

其中一个

One of the

在火星上拍了照片。

on Mars took a picture.

这太疯狂了。

That's wild.

然后是火星勘测轨道飞行器MRO也拍了照片，它拍到了最近距离的图像之一，因为它当时离火星比离地球更近。

And then MRO, the Mars Reconnaissance Orbiter, took a picture, and it got one of the closest ones because it came closer to Mars than it is to Earth.

在火星上，是的，有MRO、MAVEN和毅力号。

At Mars, yeah, it was MRO, MAVEN, and Perseverance.

就是那个。

That was the one.

太疯狂了。

That's crazy.

这相当酷。

Which is pretty cool.

我不知道。

I don't know.

所以它们都观察了，并且拍得不错。

So they all looked at it, and they get nice.

我是说，这些图像并不是特别近距离的超级特写，因为这些设备比如毅力号的设计初衷是拍摄火星表面的物体，而不是数百万英里外太空中的东西。

I mean, they're not like amazing super close-up images because these things are all like Perseverance was created to like image things on the surface of Mars, not like things in space millions of miles away.

没错。

Right.

是啊。

Yeah.

而且

And

一般来说，那些壮观的彗星在比这颗更接近太阳时才会显得壮观，因为那时它们正以极快的速度喷射物质。

typically, like, the spectacular comets become spectacular looking when they're much closer to the sun than this one is because that's when they're really boiling stuff off at a Yeah.

速度快得惊人。

At a crazy rate.

但正如我们之前提到的，这是一个学习我们无法从太阳系彗星中了解到的知识的机会，因为它们都曾被加热过。

But as we've mentioned before, it's an opportunity to learn things that we cannot learn from comets in our own solar system because they've all been heated up Yeah.

达到过这种温度，所以我们看到的不是它们的原始状态。

To this temperature before, so we're not seeing them in their pristine states.

是啊。

Yeah.

包括Punch在内的许多太阳观测航天器都观察到了它，Punch是今年早些时候才发射的。

Bunch of solar observing spacecraft looked at it, including Punch, which just launched, like, a few months ago earlier this year.

而且这是第一次，但我觉得非常有趣，因为他们进行了超级协调的观测活动，动用了大量NASA任务，跨越多个任务部门，包括太阳物理任务、行星任务和小行星表面任务。

And that and it was the first time, but, like I think it was it's super interesting because they did the super coordinated campaign across tons of NASA missions, across a bunch of mission directorates, heliophysics missions, planetary missions, and asteroid space surface missions.

我想露西号和灵神号也都观测了它。

And I think Lucy and Psyche also both looked at it.

是的。

Yep.

那么，露西团队的Audrey，你有什么内部消息可以分享给我们吗？

And, Audrey, from the Lucy team, do you have any special insider information you can share with us?

我们不会告诉别人的。

We won't tell anybody.

我的意思是，NASA简报上公布的内容就是我所知道的全部了。

The I mean, I think everything that's on the the NASA briefing is what I know.

好的。

Okay.

好的。

Okay.

那么我我应该说就内部消息而言这是个否定的回答。

So I I would take let's I would say that's a no as far as insider information.

没有。

No.

没关系。

It's okay.

没有。

No.

这也是

It's also

原本应该进行成像的，我想那些数据可能也已经发布了，但我还没看过那些。

was supposed to be doing imaging, and I think we maybe that got released too, but I haven't looked at that one.

是的。

Yeah.

还会有更多JWST的数据采集，我想应该是在十二月或一月。

There will be more JWST data taken, I think, in either December or January.

我记不清了。

I can't remember.

酷。

Cool.

请讲。

Speaking.

这些证据是否强烈表明这是一艘外星飞船？

Strongly does this evidence suggest that this is an alien spacecraft?

它强烈表明并非如此。

It strongly suggests it's not.

哦。

Oh.

是啊。

Yeah.

嗯。

Mhmm.

是的。

Yeah.

这与

It's pretty consistent with

谈谈那个锻炼。

Talk That's workout.

谈谈这与彗星相当一致。

Talk it's pretty consistent with comets.

你有在播客上听过我们说那不是彗星吗？

You ever spend on the podcast to hear us say that it was not a comet?

平衡。

Balance.

是的。

Yeah.

是的。

Yeah.

呃，奥黛丽？

Well, Audrey?

说到火星和那些火星任务，嗯哼。

Speak speaking of Mars and all those Mars missions Mhmm.

其中一些任务正在研究火星磁场的消失，这也是我们感兴趣的，因为地球同样拥有磁场。

One of those some of those missions are studying the loss of Mars' magnetic field, which is something we're interested in because Earth also has a magnetic field.

我以为你要转到火星卫星的话题上。

I thought you were gonna switch to the Mars moon topic.

不。

No.

哦。

Oh.

如果你还记得录制前的简报

If you remember the prerecording briefing

我不记得了。

I don't.

那是在真相之后。

That's after truth.

那是很久以前的事了。

That was a long time ago.

太久

So long

以前。

ago.

我刚巧妙地转到了磁场话题。

I just nailed a segue to the magnetic field.

很好。

Great.

地球有磁场。

The Earth has a magnetic field.

哇哦。

Woah.

我们刚才在讨论航天器。

And we were talking about spacecraft.

对。

Right.

是的。

Yeah.

所以这里有...

So there's there's

很高兴我们达成了共识。

Glad we're all on the same page here.

我们之前讨论过地球磁场如何随时间波动。

We've talked before about how the Earth's magnetic field fluctuates over time.

是啊。

Yeah.

说实话我觉得这挺吓人的。

I've actually find this quite terrifying.

磁场的强度会波动变化，甚至会发生翻转。

The strength of the magnetic field fluctuates over It flips.

什么鬼？

What the hell?

它有时就会翻转。

It flips sometimes.

就像现在的磁场有磁北极和磁南极，它们与地理上的南北极是相反的。

And when it's so like the magnetic field currently has magnetic north and magnetic south, which are opposite the geographic north and south.

对吧？

Right?

但我们的岩石记录显示，在地球历史上这些磁极曾多次翻转。

But like our rock record shows us that over the history of the Earth, those flip.

磁北极和磁南极会发生互换。

The magnetic north and south flip.

而在翻转过程中，正如你想象的那样，情况会变得极度混乱。

And in the in when you're in the middle of flipping, things get super chaotic as you might imagine.

是的。

Yeah.

因为可以想象这种翻转就像是它们旋转了，现在北极在这边而南极在那边。

Because it's like so one one might imagine that the flipping is like they rotate, and now north is over here and south is over there.

但可能更像是把刻度盘调低

But probably it's like turn the dial down

嗯。

Mhmm.

降到几乎为零。

Into, like, basically zero.

然后当你重新调高时，方向就反过来了。

And then when you turn it back up, it's the other way around.

正是这个调低的过程让我感到恐慌。

And it's that turning the dial down part that has me freaked out.

完成一次完整翻转需要多长时间？

How long does it take to do a full flip?

我试图弄清楚是天，还是说，比如一年？

I was trying to find day, or is it, like, a year?

不是。

No.

是一分钟吗？

Is it a minute?

数百年。

Hundreds of years.

超过一年。

It's more than a year.

对。

Yeah.

但也不至于像百万年那么久。

But it's not, like, a million years or anything like that.

这个时间尺度大概是

It's it's on the scale of

像是这些

Like these

到数千年左右吧。

to thousands of years, sort of.

我觉得大概是莫比几百年的量级。

I think it's like Morby hundreds.

对。

Yeah.

我认为

I think

几十甚至几百，因为这个周期的时长是以十万年级别来计算的。

Tens or hundreds even because the cycle the period is on the sort of hundred thousand year time scale.

对。

Yeah.

没错。

Yeah.

所以已经有迹象表明这种情况正在发生，事物开始出现波动。

So And so there's been signs that that this is happening potential that, like, things are starting to fluctuate.

就像，它稍微移动了一点，然后开始变得稍微弱一些。

Like, it moves a little bit, and it's starting to be a little bit less.

但这与那个有点关系，又有点不同，就是存在一个薄弱点。

But so this is sort of related to that, but a little bit different, and that there is a weak spot.

地球磁场中有一些较弱和较强的区域，这些会在地球上方的磁场强度中显现出来。

There are weaker spots and stronger spots in Earth's magnetic field that show up in the sort of field strength above above the Earth.

所以存在这个被称为南大西洋异常区的薄弱点。

And so there's this weak spot called the South Atlantic anomaly.

是的。

Yeah.

它位于南大西洋上方。

That's over the South Atlantic.

没错。

Yep.

聪明。

Clever.

然后还有一些更强的区域，比如加拿大上方和澳大利亚附近。

And then there's stronger spots like up in Canada and one over sort of by Australia.

它们之间不一定有直接关联，但都与磁场的生成方式等有关。

And they're like not necessarily directly related to each other, but they are related to how it's generated and all of that.

有一组名为Swarm的卫星，由三颗2014年发射的航天器组成，它们一直在观测来自地球核心、地幔、电离层和磁层的地磁场，并长期监测其变化。

There's a set of spacecraft called the Swarm satellites, which is three spacecraft that have been observing launched in 2014, and they've been observing the magnetic field from the Earth, the core, the mantle, and the atmosphere, or the ionosphere and magnetosphere, sorry, and sort of monitoring it over time.

他们发现自2014年以来，南大西洋异常区的面积增长了约1%。

They found that since 2014, the South Atlantic anomaly area has grown by about 1%.

好的。

Okay.

同时在这段时间里，磁场的强区也有所减弱。

And also the strong parts of the field have decreased in that time.

有意思。

Interesting.

所以我们都会死。

So we're all gonna die.

所以他们...我还没被说服，但我确实感到担忧。

So they I'm not convinced, but I am concerned.

地磁场反转。

Magnetic field reversal.

所以他们并没有发现反转确实正在发生。

So they didn't find that, like, the reversal is definitely happening.

但同样，我们仍然不太清楚原因

But also, we still don't really know why

那会是什么样子，或者说实际上会呈现怎样的景象。

What that would look like or what it would look like, really.

是啊。

Yeah.

真是见鬼的

For freaking the
