1
So what we're looking at over there, that's a quarter section of the Falcon 9 17-foot diameter fairing.
2
It's 17-foot diameter and 50 feet long.
3
It's capable of taking the largest satellites in the world, and it could actually literally fit a city bus in that fairing.
4
It's that big, because that's just a quarter section of it.
5
It's made of carbon fiber.
6
It's very lightweight and uses the most advanced analytical techniques to optimize the mass.
7
So it's actually, I believe, the lightest weight fairing of its kind as well.
8
What we're looking at here is the Dragon spacecraft pressure vessel.
9
So it's almost done.
10
We just need to do the forward and aft bulkheads.
11
It's actually upside down right now, but you can see the main hatch, some of the windows.
12
The actual common birthing mechanism where it births to the space station is, well, right there.
13
It doesn't ordinarily be the other way around.
14
And this is an actual flight fidelity article that's going to go through full qualification testing.
15
This area is dedicated to our Dragon spacecraft assembly.
16
So you see various tools.
17
That's for our heat shield, making the composite parts on our heat shield.
18
Over there are the side shields and the nose cone.
19
That's the engineering test article that's basically engineering pathfinder for our heat shield for Dragon which is, it's used a very advanced material called the phenolic infregnated carbon ablator
20
which is really the best heat shield material you could possibly have.
21
This is our engineering test article of our Dragon spacecraft.
22
So it's not flight fidelity.
23
The part we saw earlier where we saw the welded piece, that's actually flight fidelity, but this was used as an engineering pathfinder to figure out how we might make Dragon.
24
And actually it's been very useful.
25
On the right there is a space station birthing mechanism ring.
26
So that's an actual ring that will mate to the space station.
27
There's another one on the Dragon itself, although the guide veins aren't present.
28
Here are various pieces like windows and pushers and frangible nuts.
29
These are structural bulkheads, structural reinforcing bulkheads.
30
That's the little model we use to determine splashdown loading.
31
So here we are in the East High Bay.
32
So we have two very large high bays.
33
We're in the East one right now.
34
The East High Bay is used for Falcon 9 stage construction, and it's also temporarily used for storage, which is why you see various bits and pieces behind me.
35
This area under the high bay is used for Falcon 9 tank fabrication.
36
So you can see behind me various barrel sections for Falcon 9.
37
That's actually serial number two, that completed tank, is serial number two of Falcon 9.
38
Serial number one is on the test stand in Texas.
39
And then serial number three is in barrel sections on the floor.
40
And we're getting ready to weld together those barrel sections and create our third tank, which would actually be the first flight tank.
41
So the first one's a run tank, second one's a qualification tank, and the third one will see flight.
42
That's a Falcon 1 second stage bulge former.
43
So that's a classic bulge forming tool that's used to take two welded cones of typical refractory alloy metal like
44
plumbium and haptenium alloy and belging it to a round contour
45
which is the optimized contour for maximizing the efficiency of rocket thrust.
46
This cleaner here is also climate controlled,
47
particularly controlled and it's currently used for propulsion components as well as temporarily it's used to do composite layout.
48
So that giant tool you see there is the mandrel that's used to create the composite parts for Falcon 9.
49
So it creates the interstage, the dragon trunk section, and the propulsion section skirt.
50
Anything that's a body diameter, a 12-foot diameter, cylindrical part.
51
And that'll be moved over to the actual composites area when we have that composite preparation room down, which will be fairly soon.
52
This area is where we do a lot of the Falcon 1 structural assembly.
53
So behind me, that's a Falcon 1 half section of a nose cone.
54
That's the tool on which the nose cones are made.
55
That's an avionics payload adapter cone.
56
That's another payload adapter cone.
57
That's a mandrel for the Falcon 1 interstage, which is similar to the Falcon 9 interstage.
58
In fact, the Falcon 9 interstage is just a scaled up version of the Falcon 1 interstage.
59
This is a barrel section for Falcon 1 Flight 5.
60
So we have Flight 3 on the island in the Quagg in the Atoll ready for launch, almost ready for launch.
61
Flight 4 is going to be right behind that, will launch in about 3 or 4 months time.
62
And then this is Flight 5 which will launch sometime in the first half of the next year.
63
We have a lot of customers that are interested in that and we expect to do a deal on that pretty soon.
64
And this area is also used for composites of fabrication.
65
So we've got a big oven there which is used to put big parts in a small oven for smaller parts.
66
What we're looking at here is a Falcon 1 upper stage.
67
So you can see the engine and actuators and all that plumbing is for the attitude control system.
68
It will actually hold the pressure and bottles.
69
There's a lot more stuff that goes in the back there.
70
You can see the tank and the little skirt at the back that holds a lot of the structure.
71
That's for flight 4
72
and then the flight 5 unit is right there behind it with obviously not much stuff done on it yet.
73
This is our little snack section.
74
So we offer people at work here to get free snacks and drinks, which is kind of a common thing in the internet world, but relatively unusual in the space world.
75
And if people are working late and they need a snack or something, they should have one readily available.
76
All right, well, thanks for following me on the tour.
77
That was just SpaceX Hawthorne.
78
There's actually a lot more other SpaceX facilities.
79
We have a big test site in Texas.
80
We've got a launch pad at the Canaveral, a launch island in the Quadrillion Atoll.
81
And we're looking for great people of all kinds to join the company.
82
So if you're interested, please send us a resume.

シャドーイングとは?英語上達に効果的な理由

シャドーイング(Shadowing)は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的:ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影(shadow)」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
