00:12
So I grew up in Orlando, Florida.
0
800
3176
我在佛罗里达州的奥兰多市长大
00:16
I was the son of an aerospace engineer.
1
4000
3296
我是航空工程师的儿子
00:19
I lived and breathed the Apollo program.
2
7320
2736
阿波罗计划与我的生活息息相关
00:22
We either saw the launches
from our backyard
from our backyard
3
10080
2056
我们不是在后院里看着发射器
00:24
or we saw it by driving
in the hour over to the Cape.
in the hour over to the Cape.
4
12160
3656
就是开上好几个小时车到开普敦镇去看它
00:27
I was impressed by, obviously,
space and everything about it,
space and everything about it,
5
15840
2858
显然，空间科学对我产生了深刻的影响
00:30
but I was most impressed
by the engineering that went into it.
by the engineering that went into it.
6
18722
2905
但最让我印象深刻的是这背后的工程学
00:34
Behind me you see an amazing view,
7
22720
2696
你看到的在我身后的壮观景象
00:37
a picture that was taken
from the International Space Station,
from the International Space Station,
8
25440
3896
是一幅从国际空间站拍的图片
00:41
and it shows a portion of our planet
9
29360
2176
它展示了我们星球的一部分
00:43
that's rarely seen and rarely studied
10
31560
2416
罕见而且极少被研究的一部分
00:46
and almost never explored.
11
34000
2296
几乎从未被探索的一个地方
00:48
That place is called the stratosphere.
12
36320
2536
这一部分被称为平流层
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
如果你从地面出发一直往上往上往上
00:54
it gets colder and colder and colder,
14
42040
2576
周围会变得愈来愈冷
00:56
until you reach the beginning
of the stratosphere,
of the stratosphere,
15
44640
2376
直到你进入平流层
00:59
and then an amazing thing happens.
16
47040
2616
接下来神奇的事情发生了
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
变冷的速度变慢了许多，然后开始暖和起来
01:05
and then it gets warmer and warmer
18
53720
1656
然后越来越暖和
01:07
until the point where you can
almost survive without any protection,
almost survive without any protection,
19
55400
4936
直到你几乎不需要任何保护措施也能生存
01:12
about zero degrees,
20
60360
1816
大约到达了零度
01:14
and then you end up
getting colder and colder,
getting colder and colder,
21
62200
3295
接下来你会愈来愈冷愈来愈冷
01:17
and that's the top of the stratosphere.
22
65519
2217
这就是平流层的顶部了
01:19
It is one of the least accessible
places on our planet.
places on our planet.
23
67760
3936
这是我们这个星球极少有人到达的地方之一
01:23
Most often, when it's visited,
24
71720
1736
大多数情况下，当它被造访时，
01:25
it's by astronauts
who are blazing up at it
who are blazing up at it
25
73480
3896
那是宇航员们乘坐着火箭
01:29
at probably several times
the speed of sound,
the speed of sound,
26
77400
2856
以大约是音速数倍的速度穿过它
01:32
and they get a few seconds on the way up,
27
80280
1976
宇航员在上升时停留了几秒钟
01:34
and then they get this blazing
ball of fire coming back in,
ball of fire coming back in,
28
82280
4776
还有就是他们返航时，坐着烧成火球的返回舱
01:39
on the way back in.
29
87080
1936
回到地面上
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
但我想问的问题是，是否有可能在平流层逗留？
01:45
Is it possible to experience
the stratosphere?
the stratosphere?
31
93360
2336
是否有可能去体验平流层？
01:47
Is it possible to explore
the stratosphere?
the stratosphere?
32
95720
2520
是否有可能去探索平流层？
01:54
I studied this using
my favorite search engine
my favorite search engine
33
102640
2776
我用我最喜欢的搜索引擎来研究这个问题
01:57
for quite a while, about a year,
34
105440
3016
研究了大约有一年
02:00
and then I made a scary phone call.
35
108480
3496
然后我根据一个朋友的参考意见
02:04
It was a reference from a friend of mine
to call Taber MacCallum
to call Taber MacCallum
36
112000
3696
给Taber MacCallum打了一通吓人的电话
02:07
from Paragon Space
Development Corporation,
Development Corporation,
37
115720
2736
他在Paragon空间发展公司工作
02:10
and I asked him the question:
38
118480
1381
我问了他这个问题：
02:11
is it possible to build
39
119885
3360
有没有可能
02:16
a system to go into the stratosphere?
40
124000
2136
建造一个去平流层的系统？
02:18
And he said it was.
41
126160
1576
他回答说， “可以。”
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
此后大约过了三年，我们开始着手筹划
02:26
And on October 24 of last year,
43
134480
2480
在去年的十月24号
02:29
in this suit,
44
137680
1200
穿着这套设备
02:31
I started on the ground,
45
139440
1400
我从地面出发
02:33
I went up in a balloon to 135,890 feet --
46
141720
6040
我在一个气球中上升到离地135,890英尺的高度
02:40
but who's counting?
47
148360
1216
但谁关心数字呢？
02:41
(Laughter)
48
149600
2456
（笑声）
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
回地球的速度高达822公里每小时
02:49
It was a four-minute
and 27-second descent.
and 27-second descent.
50
157800
3040
我下降了四分27秒
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
当我到达10，000英尺，我打开降落伞然后在地面着陆
02:58
(Applause)
52
166120
4560
（鼓掌喝彩）
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
但这是一次关于科学的演讲, 关于工程技术的演讲
03:10
and what was amazing to me
about that experience
about that experience
54
178080
2296
这次体验让我感到不可思议的是
03:12
is that Taber said, yes, I think
we can build a stratospheric suit,
we can build a stratospheric suit,
55
180400
4656
Taber说，我们可以制作一套适用于平流层的装备，
03:17
and more than that, come down tomorrow
56
185080
2616
不止如此，明天过来
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
让我们和制作出装备的小组的
03:22
that actually built it.
58
190880
1200
核心人员深入探讨。
03:24
And they did something
which I think is important,
which I think is important,
59
192400
4336
他们做了一些我认为很重要的事情，
03:28
which is they took
the analogy of scuba diving.
the analogy of scuba diving.
60
196760
3336
他们参考了潜水器的设计。
03:32
So in scuba diving,
61
200120
1696
在潜水器里，
03:33
you have a self-contained system.
62
201840
1816
有一个自携装置。
03:35
You have everything
that you could ever need.
that you could ever need.
63
203680
2336
你所需要的一切都有。
03:38
You have a scuba tank.
64
206040
2040
你有一个氧气瓶。
03:40
You have a wetsuit.
65
208480
2656
你有潜水服。
03:43
You have visibility.
66
211160
1736
你有可视装置。
03:44
And that scuba is exactly this system,
67
212920
2736
潜水装置就是我们想要的系统，
03:47
and we're going to launch it
into the stratosphere.
into the stratosphere.
68
215680
2440
我们要把一种类似的装置发射到平流层去。
03:50
Three years later, this is what we have.
69
218920
2160
三年研究后，这是我们的改良装置。
03:54
We've got an amazing suit
that was made by ILC Dover.
that was made by ILC Dover.
70
222160
4696
ILC Dover为我们制作了一套令人惊叹的服装装置。
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 Dover公司提供了阿波罗计划的所有保护套装
04:02
and all of the extravehicular
activity suits.
activity suits.
72
230360
2416
和所有外太空活动的保护套装
04:04
They had never sold a suit commercially,
73
232800
3256
他们从来不向私人出售，
04:08
only to the government,
74
236080
1576
只和政府打交道，
04:09
but they sold one to me,
which I am very grateful for.
which I am very grateful for.
75
237680
3616
但他们向我提供了一套，我对此很是感激。
04:13
Up here we have a parachute.
This was all about safety.
This was all about safety.
76
241320
3160
在这里我们有一个降落伞包。安全起见。
04:17
Everyone on the team knew
77
245240
4816
我们团队里的人都知道
04:22
that I have a wife
and two small children --
and two small children --
78
250080
2736
我有妻子和两个很小的孩子 --
04:24
10 and 15 --
79
252840
2576
一个十岁另一个十五岁 ——
04:27
and I wanted to come back safely.
80
255440
2055
我想平安地回来。
04:29
So there's a main parachute
and a reserve parachute,
and a reserve parachute,
81
257519
2430
有一个主降落伞包和一个备用降落伞包，
04:31
and if I do nothing,
82
259973
1200
如果我什么都不做（译注：失去意识或行为能力），
04:33
the reserve parachute is going to open
because of an automatic opening device.
because of an automatic opening device.
83
261760
3667
备用降落伞包将会被自动启用装置打开。
04:38
The suit itself
can protect me from the cold.
can protect me from the cold.
84
266160
2136
这套保护服会为我御寒。
04:40
This area in the front here
has thermal protection.
has thermal protection.
85
268320
2936
前面的部分有高温保护装置。
04:43
It will actually heat water
that will wrap around my body.
that will wrap around my body.
86
271280
3176
它会加热环绕我身体的水。
04:46
It has two redundant oxygen tanks.
87
274480
2456
它有两个冗余的氧气瓶。
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
即使我在这套保护服上弄出一个四分之一英寸的小孔，
04:52
which is extremely unlikely,
89
280040
2576
当然这个几率很小，
04:54
this system would still protect me
from the low pressure of space.
from the low pressure of space.
90
282640
3800
这套装置依然能在低压环境中保护我。
04:59
The main advantage of this system
is weight and complexity.
is weight and complexity.
91
287320
3656
这套系统主要的优点是重量很轻，复杂性相对教低。
05:03
So the system weighs about 500 pounds,
92
291000
2976
整套系统重500磅，
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
如果跟其它穿越平流层的装备比的话，
05:09
they used a capsule.
94
297840
1256
别人使用的是太空舱。
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
制作太空舱需要极其复杂的工艺，
05:15
and it weighed about 3,000 pounds,
96
303120
1936
重量约为3000磅，
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
要让3000磅的装置升到135,000英尺，
05:21
which was my target altitude,
98
309800
2136
那是我的目标高度，
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
需要一个4.5到5千万立方英尺的气球。
05:30
Because I only weighed
500 pounds in this system,
500 pounds in this system,
100
318840
3336
而整个系统加我在内只有500磅，
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
我们可以用一个小五倍的气球代替，
05:37
and that allowed us to use a launch system
that was dramatically simpler
that was dramatically simpler
102
325440
4416
这样我们就可以用一个简便多了的发射系统
05:41
than what needs to be done
for a much larger balloon.
for a much larger balloon.
103
329880
2640
不需要那些大气球需要的复杂装备。
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
现在，我带你们看看10月24日的罗斯威尔市，在新墨西哥州。
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
我们有一个在深夜工作的伟大的团队。
05:53
And here's the suit.
106
341880
2576
这就是保护服。
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
再次说明，这是用抓钩机吊起来的，你们马上会再见到，
05:59
and I want to play you a video
of the actual launch.
of the actual launch.
108
347640
3216
我想放一段发射现场的视频。
06:02
Roswell's a great place
to launch balloons,
to launch balloons,
109
350880
2016
罗斯威尔是发射气球的好场所，
06:04
but it's a fantastic place
to land under a parachute,
to land under a parachute,
110
352920
3176
更是一个降落伞降落的绝佳场所，
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
尤其是你要从70英里的高空降落时。
06:13
That's a helium truck in the background.
112
361640
2040
背景里的是一辆装氢气的卡车。
06:16
It's darkness.
113
364360
1256
天黑了。
06:17
I've already spent about an hour
and a half pre-breathing.
and a half pre-breathing.
114
365640
3216
我已经花了一个半小时调整呼吸。
06:20
And then here you see the suit going on.
115
368880
2400
然后你看到的是装备保护服的过程。
06:24
It takes about an hour to get the suit on.
116
372960
2280
整个过程用了一个小时。
06:29
Astronauts get this really nice
air-conditioned van
air-conditioned van
117
377480
3736
宇航员乘坐空调专车去发射点
06:33
to go to the launch pad,
but I got a front loader.
but I got a front loader.
118
381240
2576
但我是被抓钩机吊着送去的。
06:35
(Laughter)
119
383840
2176
（笑声）
06:38
You can see the top.
You can see the balloon up there.
You can see the balloon up there.
120
386040
2536
你可以看见最上面。你可以看见那上面的气球。
06:40
That's where the helium is.
121
388600
1520
里面填充的是氢气。
06:44
This is Dave clearing the airspace
with the FAA for 15 miles.
with the FAA for 15 miles.
122
392640
3640
这是Dave和联邦航空管理局在帮我清出来15英里的飞行空间。
06:52
And there we go.
123
400360
1200
现在我们升空了。
06:56
(Laughter)
124
404520
1696
（笑声）
06:58
That's me waving with my left hand.
125
406240
1696
这是我在挥动我的左手。
06:59
The reason I'm waving with my left hand
126
407960
2056
我挥动左手的原因是
07:02
is because on the right hand
is the emergency cutaway.
is the emergency cutaway.
127
410040
2656
挥动右手表示紧急刹停。
07:04
(Laughter)
128
412720
1576
（笑声）
07:06
My team forbade me
from using my right hand.
from using my right hand.
129
414320
2840
我的团队禁止我用我的右手。
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.
130
419280
3336
向上的旅途十分美妙。有点像反过来播放的谷歌地图。
07:14
(Laughter)
131
422640
2816
（笑声）
07:17
It took two hours
and seven minutes to go up,
and seven minutes to go up,
132
425480
2096
向上花了两个小时七分钟，
07:19
and it was the most peaceful
two hours and seven minutes.
two hours and seven minutes.
133
427600
2736
那是最平静的两小时七分钟。
07:22
I was mostly trying to relax.
134
430360
1880
大多时间我试着放松。
07:25
My heart rate was very low
135
433920
2016
我的心率极其缓慢
07:27
and I was trying not to use
very much oxygen.
very much oxygen.
136
435960
2120
我尽可能少用氧气。
07:31
You can see how the fields
in the background
in the background
137
439840
2736
你可以在背景里看到地面建筑
07:34
are relatively big at this point,
138
442600
1616
现在还是相对比较大的，
07:36
and you can see me going up and up.
139
444240
2056
你可以看见我一直在上升。
07:38
It's interesting here,
because if you look,
because if you look,
140
446320
2016
这里十分有趣，你看，
07:40
I'm right over the airport,
and I'm probably at 50,000 feet,
and I'm probably at 50,000 feet,
141
448360
3376
我在机场的正上方，大约50,000英尺高，
07:43
but immediately I'm about to go
into a stratospheric wind
into a stratospheric wind
142
451760
2696
但马上我就要进入平流层风带
07:46
of over 120 miles an hour.
143
454480
1720
那里风的时速超过120英里。
07:51
This is my flight director telling me
that I had just gone higher
that I had just gone higher
144
459440
3736
这是我的飞行指导员告诉我
07:55
than anybody else
had ever gone in a balloon,
had ever gone in a balloon,
145
463200
2216
我比任何用气球上去的人到得更高，
07:57
and I was about 4,000 feet from release.
146
465440
3680
我离自由落体点还有4,000英尺。
08:01
This is what it looks like.
147
469680
1360
终于抵达了最终的高度
08:06
You can see the darkness of space,
the curvature of the Earth,
the curvature of the Earth,
148
474240
2905
你可以看见太空中的暗处，地球的曲线，
08:10
the fragile planet below.
149
478080
1320
底下的脆弱的星球。
08:20
I'm practicing my emergency procedures
mentally right now.
mentally right now.
150
488200
3200
当时正在脑海中演练紧急情况处理流程。
08:24
If anything goes wrong,
I want to be ready.
I want to be ready.
151
492640
2016
如果有意外发生，我希望能稳妥应对。
08:26
And the main thing that I want to do here
152
494680
2176
在这里的我想做的主要事情是
08:28
is to have a release and fall
and stay completely stable.
and stay completely stable.
153
496880
6416
稳稳当当地降落在目的地。
08:35
(Video) Ground control. Everyone ready?
154
503320
2920
（视频）地面控制台。所有人都准备好了吗？
08:43
Five. Four. Three. Two. One.
155
511720
5240
五！四！三！二！一！
08:59
Alan Eustace: There's the balloon
going by, fully inflated at this point.
going by, fully inflated at this point.
156
527840
3429
现在飘过去的是气球，已经充好气了。
09:04
And there you can see a drogue parachute,
which I'll demonstrate in just a second,
which I'll demonstrate in just a second,
157
532678
3858
现在你看到的是减速伞，我马上会介绍，
09:08
because that's really important.
158
536560
1576
因为这非常重要。
09:10
There's the balloon
going by a second time.
going by a second time.
159
538160
2000
这是第二次看到气球
09:21
Right now, I'm about
at the speed of sound.
at the speed of sound.
160
549200
2160
现在，我马上要以音速飞行。
09:24
There's nothing for me to tell
it's the speed of sound,
it's the speed of sound,
161
552640
2720
我对音速没有什么好描述的，
09:27
and very soon I will actually be
as fast as I ever get,
as fast as I ever get,
162
555880
3776
很快我就到达了所能达到的最高速，
09:31
822 miles an hour.
163
559680
1640
时速822英里。
09:49
(Video) Ground control: We lost the data.
164
577200
1953
（视频）地面控制台：我们的通信中断了
09:54
AE: So now I'm down low right now
165
582960
1616
现在我开始下降了、
09:56
and you can basically see
the parachute come out right there.
the parachute come out right there.
166
584600
5296
你们能看见降落伞在这边出现。
10:01
At this point, I'm very happy
that there's a parachute out.
that there's a parachute out.
167
589920
2762
那时，我非常开心降落伞打开了。
10:05
I thought I was the only one happy,
168
593789
1667
我以为我是唯一一个觉得开心的人，
10:07
but it turns out mission control
was really happy as well.
was really happy as well.
169
595480
3336
但我发现任务控制中心也非常开心。
10:10
The really nice thing about this
is the moment I opened --
is the moment I opened --
170
598840
3096
最妙的时刻是我打开降落伞时 --
10:13
I had a close of friend of mine,
Blikkies, my parachute guy.
Blikkies, my parachute guy.
171
601960
3376
我的好朋友，Blikkies，我的降落伞教练，
10:17
He flew in another airplane,
and he actually jumped out
and he actually jumped out
172
605360
2936
他乘坐另一架飞机，他真的在机上跳下来
10:20
and landed right next to me.
173
608320
1976
然后在我身旁降落。
10:22
He was my wingman on the descent.
174
610320
3256
他是我下降过程的军师。
10:25
This is my landing, but it's probably more
properly called a crash.
properly called a crash.
175
613600
5216
这是我的降落过程，更准确的说是撞击地面的过程。
10:30
(Laughter)
176
618840
4216
（笑声）
10:35
I hate to admit it, but this wasn't
even close to my worst landing.
even close to my worst landing.
177
623080
3456
我非常不愿意承认，这是我最最槽糕的降落。
10:38
(Laughter)
178
626560
2856
（笑声）
10:41
(Applause)
179
629440
5320
（掌声）
11:00
(Video) Man: How are you doing?
180
648160
1496
（视频）男人：你好吗？
11:01
AE: Hi there!
181
649680
1280
AE：你好啊！
11:07
Yay.
182
655280
1216
棒极了。
11:08
(Laughter)
183
656520
2296
（笑声）
11:10
So I want to tell you one thing
184
658840
1496
我想告诉你们一件事情
11:12
that you might not have seen
in that video,
in that video,
185
660360
2296
你可能没有在视频里看过，
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
但是整件事情中最重要的部分是刚刚脱离时
11:18
and what happens right after you release.
187
666560
2856
和接下来的十几秒钟。
11:21
And what we tried to do was use
something called a drogue parachute,
something called a drogue parachute,
188
669440
4296
我们尝试用了降速伞，
11:25
and a drogue parachute
was there to stabilize me.
was there to stabilize me.
189
673760
2696
降速伞是帮助我平稳下降的。
11:28
And I'll show you one of those right now.
190
676480
2056
我马上要给你展示其中一个。
11:30
If any of you have ever
gone tandem skydiving,
gone tandem skydiving,
191
678560
2640
如果你们中有人试过串联跳伞，
11:34
you probably used one of these.
192
682120
1520
你可能用过这个。
11:38
But the problem with one of these things
193
686200
1936
但还有一个问题
11:40
is right when you release,
you're in zero gravity.
you're in zero gravity.
194
688160
2936
当你自由落体是，你处于零重力。
11:43
So it's very easy for this
to just turn right around you.
to just turn right around you.
195
691120
3616
所以这个东西就很容易绕着你打转。
11:46
And before you know it,
you can be tangled up or spinning,
you can be tangled up or spinning,
196
694760
3280
在你反应过来之前，就会被缠住或者打起转来，
11:51
or you can release this drogue late,
197
699320
2656
如果你晚一点打开减速伞，
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
这时候你就会以800英里的时速下降，
11:58
and this thing is going to destroy itself
199
706080
2496
这东西就会自己被破坏
12:00
and not be very useful.
200
708600
1200
变得毫无用处。
12:03
But the guys at United Parachute
Technologies came up with this idea,
Technologies came up with this idea,
201
711400
4296
但联合降落伞科技的人想出这种办法，
12:07
and it was a roll that looks like that,
202
715720
1936
翻转看起来是这样的，
12:09
but watch what happens when I pull it out.
203
717680
2680
但我把它拉出来以后。
12:13
It's forming a pipe.
204
721560
1600
它形成了一个管道。
12:16
This pipe is so solid
205
724680
2200
这个管道非常坚固
12:20
that you can take this drogue parachute
and wrap it around,
and wrap it around,
206
728360
3776
让你可以把减速伞包裹在上面，
12:24
and there's no way
it will ever tangle with you.
it will ever tangle with you.
207
732160
2320
它就无法缠扰你了。
12:27
And that prevented
a very serious potential problem.
a very serious potential problem.
208
735680
3240
这避免了非常危险的潜在问题。
12:31
So nothing is possible
without an amazing team of people.
without an amazing team of people.
209
739560
2936
当有一个梦幻的团队是没有事情是不可能的。
12:34
The core of this was about 20 people
210
742520
2456
队伍的核心是20个成员
12:37
that worked on this for the three years,
211
745000
2096
他们在这上面花了三年，
12:39
and they were incredible.
212
747120
1616
他们非常了不起。
12:40
People asked me what the best part
of this whole thing was,
of this whole thing was,
213
748760
2776
人们问我整件事情最美妙的部分在哪，
12:43
and it was a chance
to work with the best experts
to work with the best experts
214
751560
2456
那是与最好的专业人员共事的
12:46
in meteorology and ballooning
and parachute technology
and parachute technology
215
754040
4616
在气象学，热气球和降落伞科技共事的机会
12:50
and environmental systems
and high altitude medicine.
and high altitude medicine.
216
758680
4456
还有环境系统和高空用药。
12:55
It was fantastic. It's an engineer's dream
to work with that group of people.
to work with that group of people.
217
763160
4136
那太美妙了。和他们一起共事是每个工程师梦想。
12:59
And I also at the same time
wanted to thank my friends at Google,
wanted to thank my friends at Google,
218
767320
3256
同时我想感谢在谷歌的朋友，
13:02
both for supporting me during this effort
219
770600
2856
感谢你们对我努力成果的支持
13:05
and also covering for me
in the times that I was away.
in the times that I was away.
220
773480
3296
和在我不在的时间里为我分担。
13:08
But there's one other group
I wanted to thank, and that's my family.
I wanted to thank, and that's my family.
221
776800
3296
还有另一个我想致谢的团队，我的家庭。
13:12
Yay.
222
780120
1216
你们真棒。
13:13
(Applause)
223
781360
6216
（掌声）
13:19
I would constantly give them speeches
about the safety of technology,
about the safety of technology,
224
787600
3696
我会持续不断的告诉他们科学的安全性，
13:23
and they weren't hearing any of it.
225
791320
2200
但他们一点也不会听进去。
13:27
It was super hard on them,
226
795080
1376
这对他们来说太难了，
13:28
and the only reason
that my wife put up with it
that my wife put up with it
227
796480
2576
我妻子容忍下来的唯一一个原因
13:31
was because I came back incredibly happy
after each of the 250 tests,
after each of the 250 tests,
228
799080
5496
是每次当我完成测试（共250项）测试后回到家都非常开心，
13:36
and she didn't want
to take that away from me.
to take that away from me.
229
804600
2176
她不想让我失去这份快乐。
13:38
So I want to close with a story.
230
806800
1776
我想以一个故事收场。
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
我的15岁的女儿Katelyn, 和我在车里，
13:45
and we were driving down the road,
and she was sitting there,
and she was sitting there,
232
813200
3456
我们沿着路开，她坐在那
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
她想到一个主意，她说，“爸爸，我有一个主意。”
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
我听了她的主意然后说，“Katelyn,这是不可能的。”
13:57
And she looks at me
235
825320
1616
她看着我
13:58
and she goes, "Dad,
after what you just did,
after what you just did,
236
826960
3336
她说，“爸爸，在你做到这件事情之后，
14:02
how can you call anything impossible?"
237
830320
2400
还有什么事情可以被你称作不可能的？“
14:05
And I laughed, and I said,
"OK, it's not impossible,
"OK, it's not impossible,
238
833760
3256
我大笑，然后我说，”好的，这不是不可能的，
14:09
it's just very, very hard."
239
837040
2400
只是非常，非常的困难。”
14:12
And then I paused for a second,
and I said, "Katelyn,
and I said, "Katelyn,
240
840840
2896
然后我停顿了一秒，接着说，“Katelyn,
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
或许并不是不可能，甚至也不是难，
14:19
it's just that I don't know how to do it."
242
847520
2776
而只是因为我不知道怎么实现它。”
14:22
Thank you.
243
850320
1216
谢谢你们
14:23

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.
