Shadowing Practice: The Goofiest Space Experiment In History - Learn English Speaking with Video

1
Did you know that this is the biggest object humans have ever sent into space?
2
It may not look like it, but this is actually a 20 kilometer long piece of wire.
3
That's as tall as the Empire State Building.
4
Well, 45 of them.
5
But what's he doing there?
6
It must be the universe's longest string telephone!
7
Hello?
8
Hello?
9
Prepare for invasion of Earth- Oh, that's not good.
10
To actually understand what it's for, we need to look at Faraday's Law of Induction.
11
If I move this loop of wire through this magnetic field, a small current is produced.
12
You can increase the power generated by using more wire and moving it faster.
13
In fact, stick a propeller on the end and now you have yourself a wind turbine.
14
This concept made the big brains at NASA go...
15
You know how, like, the Earth is like, basically a giant magnet?
16
Yeah, bro, totally.
17
What if we use like.. a super long wire, bro?
18
Huh?
19
So 400 million dollars later, this is the plan they came up with.
20
Earth has big magnetic field, so we send spaceship with big wire.
21
But Earth magnetic field very weak, so we send even bigger wire.
22
Then we move spaceships super fast to generate power.
23
Then we rule the galaxy.
24
The system was called the TSS-1, or Tethered Satellite System.
25
1. It had a base satellite, a sub-satellite, and a 20 kilometer long conductive tether connecting them both acting as the wire.
26
Now you may have noticed something wrong here.
27
In our original example we used a loop of wire because electricity needs a closed loop to flow, and this tether is not a loop.
28
But electricity is really just the flow of electrons, and turns out there's a layer of the Earth's atmosphere called the ionosphere, which has a bunch of free electrons just floating around.
29
So using a fancy electron collector and emitter, NASA designed a system to create electron flow using the ionosphere, completing the loop.
30
In 1992, TSS-1 was launched aboard Space Shuttle Atlantis.
31
It successfully reached the ionosphere, and it was finally time to unfurl the 20 kilometer long tether.
32
Uh, Houston, we have a problem.
33
This screw isn't gonna cut it.
34
Okay, swap them out then.
35
Hey, we should test everything again to make sure it works, right?
36
Nah, it should be good.
37
It was not good.
38
That beefy screw caused the tether reel to jam up but a whopping 260 meters.
39
Pretty much 1% of its maximum length.
40
Moral of the story, always test and retest after making any design changes.
41
Quite the expensive lesson to learn, but surely they'll get it next time, right?
42
Right!
43
Ooh, we made it past 260 meters this time! and the tether successfully deployed to its full length of 20 kilom- Um,
44
Houston, we have a pro- It was so close, but when the tether reached 19.7 kilometers,
45
a small defect in the insulation near the bottom led to a large arc that melted it.
46
And that's how we ended up here.
47
A giant space noodle floating in the sky.
48
It was sighted all over the world, like in Australia, in Hawaii, in Southern USA...
49
And a few weeks later, it re-entered the atmosphere, cooking the space noodle once and for all.
50
But the big question is, did the experiment work though?
51
Well, NASA managed to collect some data, and the tether generated almost 3.5 kilowatts of electrical power.
52
Enough to run three toasters at once!
53
Okay, that doesn't seem like much, but for context, most small satellites only need one toaster amount of power.
54
But despite this, the tethered satellite system missions were abandoned.
55
And the results weren't publicized.
56
Well, apart from being roasted by the media.
57
I guess it is kind of embarrassing to have your mistake plastered in the sky for the whole world to see, but I really hope they try again.
58
Because I imagine a night sky in the future where space noodles hang from every spaceship and satellite.
59
Hashtag, bring back space noodles.
60
Please, I haven't seen the sun in years.
61
See you next time!

Wat is de Shadowing-techniek?
Shadowing is een wetenschappelijk onderbouwde taalleermethode die oorspronkelijk is ontwikkeld voor professionele tolkentraining en gepopulariseerd door polyglot Dr. Alexander Arguelles. De methode is eenvoudig maar krachtig: je luistert naar native Engelse audio en herhaalt het onmiddellijk hardop — als een schaduw die de spreker volgt met slechts 1–2 seconden vertraging. In tegenstelling tot passief luisteren of grammaticadrills, dwingt shadowing je hersenen en mondspieren om echte spraakpatronen tegelijkertijd te verwerken en te reproduceren. Onderzoek toont aan dat het de uitspraaknauwkeurigheid, intonatie, ritme, verbonden spraak, luisterbegrip en spreekvaardigheid aanzienlijk verbetert — waardoor het een van de meest effectieve methoden is voor IELTS Speaking-voorbereiding en echte Engelse communicatie.
