私はフロリダ州オーランドで育ちました
00:16
I was the son of an aerospace engineer.

父は航空宇宙学の技術者でしたから
00:19
I lived and breathed the Apollo program.

私はアポロ計画の申し子のようなものです
00:22
We either saw the launches
from our backyard

or we saw it by driving
in the hour over to the Cape.

I was impressed by, obviously,
space and everything about it,

2858
私は もちろん宇宙やその他すべてに
感銘を受けましたが
感銘を受けましたが
00:30
but I was most impressed
by the engineering that went into it.

何よりも工学の粋に引かれたのです
00:34
Behind me you see an amazing view,
7
22720
2696
私の後ろにご覧いただいているのは
00:37
a picture that was taken
from the International Space Station,
from the International Space Station,
8
25440
3896
国際宇宙ステーションで撮られた
すばらしい写真ですが
すばらしい写真ですが
00:41
and it shows a portion of our planet
9
29360
2176
そこに写っているのは
00:43
that's rarely seen and rarely studied
10
31560
2416
めったにお目にかかることはなく
研究もほとんどされず
研究もほとんどされず
00:46
and almost never explored.
11
34000
2296
探索も行われてこなかった
地球の珍しい場所です
地球の珍しい場所です
00:48
That place is called the stratosphere.
12
36320
2536
この場所は成層圏と呼ばれています
00:50
If you start on the planet
and you go up and up and up,
and you go up and up and up,
13
38880
3136
地上から上昇していくと
00:54
it gets colder and colder and colder,
14
42040
2576
どんどん寒くなっていき
00:56
until you reach the beginning
of the stratosphere,
of the stratosphere,
15
44640
2376
やがて 成層圏に到達しますが
00:59
and then an amazing thing happens.
16
47040
2616
ここで 不思議なことが起こります
01:01
It gets colder at a much slower rate,
and then it starts warming up,
and then it starts warming up,
17
49680
4016
気温の低下はゆっくりになり
やがて今度は上昇し始め
やがて今度は上昇し始め
01:05
and then it gets warmer and warmer
18
53720
1656
更に気温が上がっていって
01:07
until the point where you can
almost survive without any protection,
almost survive without any protection,
19
55400
4936
防護がなくても 生き延びられそうな
01:12
about zero degrees,
20
60360
1816
約０度に達します
01:14
and then you end up
getting colder and colder,
getting colder and colder,
21
62200
3295
そして 成層圏の頂上で
01:17
and that's the top of the stratosphere.
22
65519
2217
再び 気温がぐっと下がります
01:19
It is one of the least accessible
places on our planet.
places on our planet.
23

3936
地球上でも行くのが難しい場所のひとつです
01:23
Most often, when it's visited,
24
71720
1736
誰か訪れた人がいるとすれば
01:25
it's by astronauts
who are blazing up at it
who are blazing up at it
25
73480
3896
それは宇宙飛行士ですが
01:29
at probably several times
the speed of sound,
the speed of sound,
26
77400
2856
彼らはおそらく音速の何倍もの速さで
01:32
and they get a few seconds on the way up,
27
80280
1976
打ち上げられて そこを通り過ぎ
01:34
and then they get this blazing
ball of fire coming back in,
ball of fire coming back in,
28
82280
4776
帰還する時も火の玉となって
01:39
on the way back in.
29
87080
1936
地上へと戻ってきます
01:41
But the question I asked is, is it
possible to linger in the stratosphere?
possible to linger in the stratosphere?
30
89040
4296
でも 私が知りたいことは
成層圏に留まれないかという事です
成層圏に留まれないかという事です
01:45
Is it possible to experience
the stratosphere?
the stratosphere?
31
93360
2336
成層圏を体験できないでしょうか？
01:47
Is it possible to explore
the stratosphere?
the stratosphere?
32
95720
2520
何とか探索できないものでしょうか？
01:54
I studied this using
my favorite search engine
my favorite search engine
33
102640
2776
私はお気に入りの検索エンジンで
01:57
for quite a while, about a year,
34
105440
3016
しばらく 一年ほど調べて
02:00
and then I made a scary phone call.
35
108480
3496
恐る恐る電話を掛けました
02:04
It was a reference from a friend of mine
to call Taber MacCallum

36
112000

友人の紹介で
パラゴン・スペース・デベロップメントの
パラゴン・スペース・デベロップメントの
02:07
from Paragon Space
Development Corporation,
Development Corporation,
37
115720
2736
テーバー・マッカラムに連絡し
02:10
and I asked him the question:
38
118480
1381
そして彼に尋ねたのです
02:11
is it possible to build
39
119885
3360
成層圏に行くシステムを―
02:16
a system to go into the stratosphere?
40
124000
2136
構築できないだろうか？と
02:18
And he said it was.
41
126160
1576
彼はできると答えました
02:19
And after a period of about three years,
we proceeded to do just that.
we proceeded to do just that.
42
127760
6696
そして 約３年の歳月をかけて
完成させたのです
完成させたのです
02:26
And on October 24 of last year,
43
134480
2480
そして昨年の10月24日
02:29
in this suit,
44
137680
1200
このスーツを着て
02:31
I started on the ground,
45
139440
1400
地上から
02:33
I went up in a balloon to 135,890 feet --
46
141720
6040
気球で高度40kmまで上昇し―
02:40
but who's counting?
47
148360
1216
誰が数えたのでしょうね？
02:41
(Laughter)
48
149600
2456
（笑）
02:44
Came back to Earth
at speeds of up to 822 miles an hour.
at speeds of up to 822 miles an hour.
49
152080
4400
時速1,300メートルで地上に戻ってきました
02:49
It was a four-minute
and 27-second descent.
and 27-second descent.
50
157800
3040
４分27秒の降下です
02:53
And when I got to 10,000 feet,
I opened a parachute and I landed.
I opened a parachute and I landed.
51
161600
4080
高度３kmでパラシュートを開いて
着地しました
着地しました
02:58
(Applause)
52
166120
4560
（拍手）
03:06
But this is really a science talk,
and it's really an engineering talk,
and it's really an engineering talk,
53
174000
4056
確かに これは科学や工学の話ですが
03:10
and what was amazing to me
about that experience
about that experience
54
178080
2296
何よりこの経験で素晴らしかったことは
03:12
is that Taber said, yes, I think
we can build a stratospheric suit,
we can build a stratospheric suit,
55
180400
4656
テーバーから
成層圏用のスーツは作れると思うが
成層圏用のスーツは作れると思うが
03:17
and more than that, come down tomorrow
56
185080
2616
それよりも明日来社して
03:19
and let's talk to the team
that formed the core of the group
that formed the core of the group
57
187720
3136
実際にスーツを作成するグループの
中心メンバーと
中心メンバーと
03:22
that actually built it.
58
190880
1200
話し合ってみないかと言ってくれたことでした
03:24
And they did something
which I think is important,
which I think is important,
59
192400
4336
そこで私が重要だと思ったのは
03:28
which is they took
the analogy of scuba diving.
the analogy of scuba diving.
60
196760
3336
彼らがスキューバダイビングに
例えたことでした
例えたことでした
03:32
So in scuba diving,
61
200120
1696
スキューバダイビングでは
03:33
you have a self-contained system.
62
201840
1816
自己完結システムが必要となります
03:35
You have everything
that you could ever need.
that you could ever need.
63
203680
2336
必要なものはすべて持参します
03:38
You have a scuba tank.
64
206040
2040
スキューバタンクが必要です
03:40
You have a wetsuit.
65
208480
2656
ウェットスーツも要ります
03:43
You have visibility.
66
211160
1736
視界も確保します
03:44
And that scuba is exactly this system,
67
212920
2736
スキューバは こういったシステムで
03:47
and we're going to launch it
into the stratosphere.
into the stratosphere.
68
215680
2440
これを成層圏に持ち込むわけです
03:50
Three years later, this is what we have.
69
218920
2160
これが それから３年後の成果です
03:54
We've got an amazing suit
that was made by ILC Dover.
that was made by ILC Dover.
70
222160
4696
ILC ドーバー社製の
素晴らしいスーツができました
素晴らしいスーツができました
03:58
ILC Dover was the company
that made all of the Apollo suits
that made all of the Apollo suits
71
226880
3456
ILC ドーバー社は アポロの宇宙服をはじめ
04:02
and all of the extravehicular
activity suits.
activity suits.
72
230360
2416
数々の船外活動用スーツを作った企業です
04:04
They had never sold a suit commercially,
73
232800
3256
今まで スーツを市販したことはなく
04:08
only to the government,
74
236080
1576
専ら政府機関向けでした
04:09
but they sold one to me,
which I am very grateful for.
which I am very grateful for.
75
237680
3616
でも 私に売ってくれました
とても感謝しています
とても感謝しています
04:13
Up here we have a parachute.
This was all about safety.
This was all about safety.
76
241320
3160
こちらにはパラシュートがあり
安全のためのものです
安全のためのものです
04:17
Everyone on the team knew
77
245240
4816
チームの誰もが
04:22
that I have a wife
and two small children --
and two small children --
78
250080
2736
私には妻と２人の子どもがいる事を
知っていました
知っていました
04:24
10 and 15 --
79
252840
2576
まだ10歳と15歳です―
04:27
and I wanted to come back safely.
80
255440
2055
無事に帰ってこなくては
04:29
So there's a main parachute
and a reserve parachute,
and a reserve parachute,
81
257519
2430
ですから予備のパラシュートもあります
04:31
and if I do nothing,
82
259973
1200
もし 私が何もしなくても
04:33
the reserve parachute is going to open
because of an automatic opening device.
because of an automatic opening device.
83
261760
3667
予備のパラシュートが自動的に開く仕組みです
04:38
The suit itself
can protect me from the cold.
can protect me from the cold.
84
266160
2136
スーツ自体が私を寒さから守ってくれます
04:40
This area in the front here
has thermal protection.
has thermal protection.
85
268320
2936
正面のこの場所に温度保護機能があります
04:43
It will actually heat water
that will wrap around my body.
that will wrap around my body.
86
271280
3176
温水で私の体を覆うのです
04:46
It has two redundant oxygen tanks.
87
274480
2456
そして ２つの酸素タンク
04:48
Even if I was to get
a quarter-inch hole in this suit,
a quarter-inch hole in this suit,
88
276960
3056
わずかな穴がスーツに空いたとしても
04:52
which is extremely unlikely,
89
280040
2576
そんなことはまず起こらないでしょうが
04:54
this system would still protect me
from the low pressure of space.
from the low pressure of space.
90
282640
3800
このシステムは宇宙の低気圧から
私を保護してくれます
私を保護してくれます
04:59
The main advantage of this system
is weight and complexity.
is weight and complexity.
91
287320
3656
このシステムの最も優れた点は
その重さと精巧さです
その重さと精巧さです
05:03
So the system weighs about 500 pounds,
92
291000
2976
このシステムは約200kgありますが
05:06
and if you compare it to the other attempt
recently to go up in the stratosphere,
recently to go up in the stratosphere,
93
294000
3816
最近 成層圏へ行った装備と比べると
05:09
they used a capsule.
94
297840
1256
彼らはカプセルを使用しました
05:11
And to do a capsule, there's an amazing
amount of complexity that goes into it,
amount of complexity that goes into it,
95
299120
3976
カプセルには複雑なシステムが積み込めますが
05:15
and it weighed about 3,000 pounds,
96
303120
1936
重さは およそ1,400kgにも達します
05:17
and to raise 3,000 pounds
to an altitude of 135,000 feet,
to an altitude of 135,000 feet,
97
305080
4696
その重量を高度40kmまで
打ち上げるとなると―
打ち上げるとなると―
05:21
which was my target altitude,
98
309800
2136
そこへ私は行きたかったわけですが
05:23
it would have taken a balloon
that was 45 to 50 million cubic feet.
that was 45 to 50 million cubic feet.
99
311960
5160
14万立方メートルもの気球が必要になります
05:30
Because I only weighed
500 pounds in this system,
500 pounds in this system,
100
318840
3336
私の場合はたったの200kgですから
05:34
we could do it with a balloon
that was five times smaller than that,
that was five times smaller than that,
101
322200
3216
５分の１の大きさの気球で済みます
05:37
and that allowed us to use a launch system
that was dramatically simpler
that was dramatically simpler
102
325440
4416
ですから 大きな気球が必要なシステムよりも
05:41
than what needs to be done
for a much larger balloon.
for a much larger balloon.
103
329880
2640
打ち上げシステムが
遥かにシンプルになります
遥かにシンプルになります
05:45
So with that, I want to take you
to Roswell, New Mexico, on October 24.
to Roswell, New Mexico, on October 24.
104
333480
4656
さて これで10月24日の
ニューメキシコ州のロズウェルに行きましょう
ニューメキシコ州のロズウェルに行きましょう
05:50
We had an amazing team
that got up in the middle of the night.
that got up in the middle of the night.
105
338160
3696
チームが真夜中に待機してくれています
05:53
And here's the suit.
106
341880
2576
そして このスーツです
05:56
Again, this is using the front loader
that you'll see in a second,
that you'll see in a second,
107
344480
3136
これは使用したフロントローダーです
05:59
and I want to play you a video
of the actual launch.
of the actual launch.
108
347640
3216
実際の打ち上げのビデオを流したいと思います
06:02
Roswell's a great place
to launch balloons,
to launch balloons,
109
350880
2016
ロズウェルは気球を打ち上げるのに
適した場所ですが
適した場所ですが
06:04
but it's a fantastic place
to land under a parachute,
to land under a parachute,
110
352920
3176
パラシュートで着陸するのにも
素晴らしい所です
素晴らしい所です
06:08
especially when you're going to land
70 miles away from the place you started.
70 miles away from the place you started.
111
356120
4400
何しろ 打上げ地点から100km以上離れた
場所に着地するのですからね
場所に着地するのですからね
06:13
That's a helium truck in the background.
112
361640
2040
ヘリウムのトラックが後ろに見えます
06:16
It's darkness.
113
364360
1256
真っ暗です
06:17
I've already spent about an hour
and a half pre-breathing.
and a half pre-breathing.
114
365640
3216
一時間半ほどかけて準備しました
06:20
And then here you see the suit going on.
115
368880
2400
スーツを着せてもらっています
06:24
It takes about an hour to get the suit on.
116
372960
2280
これを着るのに一時間ほどかかりました
06:29
Astronauts get this really nice
air-conditioned van

3736
宇宙飛行士は
空調のよくきいたバンに乗って行きますが
空調のよくきいたバンに乗って行きますが
06:33
to go to the launch pad,
but I got a front loader.
but I got a front loader.
118
381240
2576
私はフロントローダーです
06:35
(Laughter)
119
383840
2176
（笑）
06:38
You can see the top.
You can see the balloon up there.
You can see the balloon up there.
120
386040
2536
上部をご覧ください
そこには気球が見えますね
そこには気球が見えますね
06:40
That's where the helium is.
121
388600
1520
ヘリウムはここに入れます
06:44
This is Dave clearing the airspace
with the FAA for 15 miles.
with the FAA for 15 miles.
122
392640
3640
デイブが連邦航空局と連絡を取り
20kmの空間を確保しています
20kmの空間を確保しています
06:52
And there we go.
123
400360
1200
さあ 私達の番です
06:56
(Laughter)
124
404520
1696
（笑）
06:58
That's me waving with my left hand.
125
406240
1696
左手を振っているのが私です
06:59
The reason I'm waving with my left hand
126
407960
2056
左手を振るのには理由があります
07:02
is because on the right hand
is the emergency cutaway.
is the emergency cutaway.
127
410040
2656
右手だと 非常事態発生という意味だからです
07:04
(Laughter)
128
412720
1576
（笑）
07:06
My team forbade me
from using my right hand.
from using my right hand.
129
414320
2840
右手を使うのはチームに禁止されました
07:11
So the trip up is beautiful.
It's kind of like Google Earth in reverse.
It's kind of like Google Earth in reverse.

実に美しい
グーグルアースを逆回転したみたいです

とにかくリラックスしようと心がけました
07:25
My heart rate was very low

07:27
and I was trying not to use
very much oxygen.

07:36
and you can see me going up and up.

And the main thing that I want to do here
152

ここで一番大切なことは
08:28
is to have a release and fall

There's nothing for me to tell
it's the speed of sound,
it's the speed of sound,
161
552640
2720
音速だといっても私にはわかりません
09:27
and very soon I will actually be
as fast as I ever get,

and you can basically see
the parachute come out right there.

166

パラシュートがここで開くはずです
10:01
At this point, I'm very happy
that there's a parachute out.

ここで パラシュートが出て
心から安心しました

10:05
I thought I was the only one happy,
168

but it turns out mission control
was really happy as well.
was really happy as well.
169

それは管制塔も同様でした
10:10
The really nice thing about this
is the moment I opened --

10:20
and landed right next to me.
173
608320
1976
隣に着陸してくれました
10:22
He was my wingman on the descent.
174
610320
3256
彼は降下のサポート役なんです
10:25
This is my landing, but it's probably more
properly called a crash.
properly called a crash.
175
613600
5216
これで私が着地したわけですが
むしろ衝突と言ったほうがいいですね

10:30
(Laughter)

10:35
I hate to admit it, but this wasn't
even close to my worst landing.

177
623080

認めたくはありませんが
もっとひどい着地もあったんです

649680
1280
アラン: やあ みんな！
11:07
Yay.
182
655280
1216
やった
11:08
(Laughter)
183
656520
2296
（笑）
11:10
So I want to tell you one thing
184
658840
1496
ビデオではお見せできなかったことを
11:12
that you might not have seen
in that video,
in that video,
185
660360
2296
お話ししたいと思います
11:14
but one of the most critical parts
of the entire thing was the release
of the entire thing was the release
186
662680
3856
最も大切なのはリリース時と
11:18
and what happens right after you release.
187
666560
2856
リリース直後に起こることです
11:21
And what we tried to do was use
something called a drogue parachute,
something called a drogue parachute,
188
669440
4296
減速用パラシュートというものを使って
11:25
and a drogue parachute
was there to stabilize me.
was there to stabilize me.
189
673760
2696
自分の体を安定させるのです
11:28
And I'll show you one of those right now.
190
676480
2056
ひとつお目にかけます
11:30
If any of you have ever
gone tandem skydiving,
gone tandem skydiving,
191
678560
2640
タンデムでスカイダイビングを
したことがある人は
したことがある人は
11:34
you probably used one of these.
192
682120
1520
使ったことがあると思います
11:38
But the problem with one of these things
193
686200
1936
ここで問題となるのは
11:40
is right when you release,
you're in zero gravity.
you're in zero gravity.
194
688160
2936
リリース時は 重力が０になります
11:43
So it's very easy for this
to just turn right around you.
to just turn right around you.
195
691120
3616
ですから 簡単に体に巻きついてしまいます
11:46
And before you know it,
you can be tangled up or spinning,
you can be tangled up or spinning,
196
694760
3280
気が付くと絡まったり
回転したりして
回転したりして
11:51
or you can release this drogue late,
197
699320
2656
減速用パラシュートを開くのが
遅れてしまいます
遅れてしまいます
11:54
in which case what happens
is you're going down at 800 miles an hour,
is you're going down at 800 miles an hour,
198
702000
4056
時速1,300kmで降下する時に
それが起こると
それが起こると
11:58
and this thing is going to destroy itself
199
706080
2496
パラシュート自体が壊れてしまい
12:00
and not be very useful.
200
708600
1200
役に立たなくなります
12:03
But the guys at United Parachute
Technologies came up with this idea,
Technologies came up with this idea,
201
711400
4296
ユナイテッド・パラシュート
テクノロジーの人達が解決策を考えました
テクノロジーの人達が解決策を考えました
12:07
and it was a roll that looks like that,
202
715720
1936
見たとおり巻いてありますが
12:09
but watch what happens when I pull it out.
203
717680
2680
引っ張るとどうなるでしょうか
12:13
It's forming a pipe.
204
721560
1600
パイプのような形状になります
12:16
This pipe is so solid
205
724680
2200
このパイプは固いので
12:20
that you can take this drogue parachute
and wrap it around,
and wrap it around,
206
728360
3776
減速用パラシュートを引っ張り出して
保護し

12:24
and there's no way
it will ever tangle with you.
it will ever tangle with you.
207
732160
2320
人とからまることはありません
12:27
And that prevented
a very serious potential problem.
a very serious potential problem.
208
735680
3240
これで深刻な問題を防ぐことができます
12:31
So nothing is possible
without an amazing team of people.
without an amazing team of people.
209
739560
2936
この素晴らしいチームがいなければ
何も叶うことはなかったでしょう
何も叶うことはなかったでしょう
12:34
The core of this was about 20 people
210
742520
2456
約20人の人たちを中心に
12:37
that worked on this for the three years,
211
745000
2096
３年の歳月をかけたのですが
12:39
and they were incredible.
212
747120
1616
誰もが有能でした
12:40
People asked me what the best part
of this whole thing was,

213
748760
2776
この計画で素晴らしかったことは
何よりも

12:43
and it was a chance
to work with the best experts

And I also at the same time
wanted to thank my friends at Google,
wanted to thank my friends at Google,
218
767320
3256
グーグルの友人達にも感謝します
13:02
both for supporting me during this effort

13:05
and also covering for me
in the times that I was away.
in the times that I was away.
220

But there's one other group
I wanted to thank, and that's my family.

13:19
I would constantly give them speeches
about the safety of technology,
about the safety of technology,
224
787600
3696
私は何度も技術の安全性を説明しましたが
13:23
and they weren't hearing any of it.
225
791320
2200
誰にも聞いてはもらえませんでした
13:27
It was super hard on them,
226
795080
1376
家族にとっては耐え難い事だったのです
13:28
and the only reason
that my wife put up with it
that my wife put up with it
227
796480
2576
それでも妻が我慢してくれたのは
13:31
was because I came back incredibly happy
after each of the 250 tests,
after each of the 250 tests,
228
799080
5496
250回に及ぶテストの度に
私が上機嫌で帰ってきたからです

to take that away from me.
to take that away from me.
229
804600
2176
それを邪魔する気にはなれなかったのです
13:38
So I want to close with a story.
230
806800
1776
さて 最後にもう１つお話しします
13:40
My daughter Katelyn, my 15-year-old,
she and I were in the car,
she and I were in the car,
231
808600
4576
15歳の娘のケイトリンと一緒に
13:45
and we were driving down the road,
and she was sitting there,
and she was sitting there,
232
813200
3456
車に乗っていた時に
娘が何かを思いつきました
娘が何かを思いつきました
13:48
and she had this idea, and she goes,
"Dad, I've got this idea."
"Dad, I've got this idea."
233
816680
3376
「お父さん 考えたの」
13:52
And so I listened to her idea
and I said, "Katelyn, that's impossible."
and I said, "Katelyn, that's impossible."
234
820080
4520
それを聞いて私は
「ケイトリン それは不可能だ」
「ケイトリン それは不可能だ」
13:57
And she looks at me
235
825320
1616
娘は私を見ました
13:58
and she goes, "Dad,
after what you just did,
after what you just did,
236
826960
3336
「でも お父さんは成功したのよ
14:02
how can you call anything impossible?"
237
830320
2400
不可能だなんてことが言えるの？」
14:05
And I laughed, and I said,
"OK, it's not impossible,
"OK, it's not impossible,
238
833760
3256
私は笑って認めました
「確かに 不可能ではないね
「確かに 不可能ではないね
14:09
it's just very, very hard."
239
837040
2400
非常に難しいだけだ」
14:12
And then I paused for a second,
and I said, "Katelyn,
and I said, "Katelyn,
240
840840
2896
そして その後に続けたのです
「ケイトリン―
「ケイトリン―
14:15
it may not be impossible,
it may not even be very, very hard,
it may not even be very, very hard,
241
843760
3736
それは不可能ではない
難しいわけでもない
難しいわけでもない
14:19
it's just that I don't know how to do it."
242
847520
2776
ただ その方法が私に分からないだけだ」
14:22
Thank you.

ABOUT THE SPEAKER
Alan Eustace - Stratospheric explorerAlan Eustace leapt to Earth from the edge of the stratosphere wearing only a spacesuit, shattering skydiving records and potentially revolutionizing the commercial space industry.
Why you should listen
Two years after Felix Baumgartner jumped from a capsule in the stratosphere for Red Bull, a quiet group led by now-retired Google exec Alan Eustace beat the height record -- without a capsule. (Neither livestreamed nor promoted, the jump record was announced the next day.) In a custom 500-pound spacesuit, Eustace was strapped to a weather balloon, and rose to a height of over 135,000 feet, where he dove to Earth at speeds exceeding 821 mph -- breaking both the sound barrier and previous records for high-altitude jumps.
Leading up to this jump, Eustace and his partners in StratEx had spent years solving a key problem of stratosphere exploration: returning human beings to Earth from the edge of space using minimal life-support systems. In the process, they’ve opened the door to cheaper and safer near-space travel.
