1
It'll be about 30 times faster than a bullet from a handgun.
2
30 times faster than a bullet from a handgun and it's the size of a skyscraper.
3
Yes.
4
Yeah.
5
That's fast.
6
It's so wild!
7
It's so wild to see, man.
8
It's so exciting.
9
The factory is so exciting too, because like genuinely, no bullshit, I felt like I was witnessing history and the sheer numbers of them that you guys are making.
10
And then this is a version and you have a new updated version that's coming soon.
11
And what is the difference?
12
It's a little longer.
13
More pointy?
14
It's the same amount of pointy, but it's got a bit more length.
15
The interstage, you see that interstage section with the grill area?
16
That's now integrated with the boost stage.
17
So we do what's called hot staging, where we light the ship engines while it's still attached to the booster.
18
The booster engines are still thrusting, it's still being pushed forward by the booster of the ship.
19
But then we light the ship engines and the ship engines actually pull away from the booster, even though the booster engines are still firing.
20
Whoa!
21
So it's blasting flame through that grill section, where we integrate that grill section into the boost stage with the next version of the rocket.
22
And the next version of the rocket will have the Raptor 3 engines, which are a huge improvement.
23
You may have seen them in the lobby, because we've got the Raptor 1, 2, and 3.
24
you can see the dramatic improvement in simplicity.
25
We should probably put a plaque there to also show how much we reduced the weight, the cost, and improve the efficiency and the thrust.
26
So the Raptor 3 has almost twice the thrust of Raptor 1.
27
Wow.
28
So you see Raptor 3, it looks like it's got parts missing.
29
It's very, very clean.
30
How many of them are on the rocket?
31
There's 33 on the booster.
32
And each Raptor engine is producing twice as much thrust as all four engines on a 747.
33
Wow.
34
So that engine is smaller than a 747 engine, but is producing almost 10 times the thrust of a 747 engine.
35
So extremely high power to weight ratio.
36
So when you're designing these, you get to Raptor 1, you see its efficiency, you see where you can improve it, you get to Raptor 2.
37
How far can you scale this up with just the same sort of technology, with propellant and ignition and engines?
38
Like how much further can you?
39
We're pushing the limits of physics here.
40
So really, in order to make a fully reusable orbital rocket, which no one has succeeded in doing yet, including us, but Starship is the first time
41
that there is a design for a rocket where full and rapid reusability is actually possible.
42
So it was not, there's not even been a design before where it was possible.
43
So we live on a planet where the gravity is quite high, like Earth's gravity is quite high.
44
If the gravity was even 10 or 20 percent higher, we'd be stuck on Earth forever.
45
We could not use, certainly couldn't use conventional rockets.
46
On the other hand, if Earth's gravity was just a little lower, like even 10-20% lower, then getting to orbit would be easy.
47
It's like if this was a video game, it's set to like maximum difficulty, but not impossible.
为什么练习与这个视频对话？
练习与这个视频对话，能够帮助提升你的英语口语表达能力。视频中的内容涉及前沿科学和技术，使用了大量专业术语和复杂句型，能够真实模拟日常和专业环境下的对话。通过跟读与模仿，学习者不仅可以增强口语流利度，还能提升对话时的自信心。此外，跟随视频的节奏进行英语影子跟读，能帮助你更好地理解语音语调，从而使你的发音更加准确。
语法与表达在上下文中
- 比较级和最高级: 例如，视频中提到了“几乎是747引擎的十倍推力”，这种表达方式强调了数量上的巨大的差异，增强了语言的表现力。
- 条件句: 讲述“如果重力高10%或20%”，通过条件句，展示了情境的假设，为听众提供了更多思考的空间。
- 动词时态: 使用现在时和将来时（例如“我们将会看到”），能够给予表达清晰的时间框架，让信息更加直观。
- 被动语态: 例如“将会被整合”，这在技术讨论中非常常见，通过被动语态突出了动作对主题的重要性，而不是施动者。
常见的发音陷阱
在视频中，有几个发音容易混淆，与发音有关的技巧也很重要。首先，“thrust”（推力）这个词在发音时，注意舌头的位置需要正确放置在牙齿之间，这样才能发出清晰的音。其次，"Raptor"的发音，特别是在集体讨论时，容易快速吞音，注意在联系上下文时发音的清晰度。此外，“engine”的发音也需要多加练习，在短语中时常会影响整句的流畅性。通过英语口语练习，让自己的发音更趋于自然流畅，无论是在正式场合还是雅思口语练习中，良好的发音都至关重要。
什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
