from our backyard
in the hour over to the Cape.
space and everything about it,
都印象深刻,
by the engineering that went into it.
from the International Space Station,
and you go up and up and up,
一路不斷向上爬升,
of the stratosphere,
and then it starts warming up,
然後會開始變暖和,
almost survive without any protection,
也能活下來的程度,
getting colder and colder,
places on our planet.
能前往的地方。
who are blazing up at it
the speed of sound,
ball of fire coming back in,
會有一團火球,
possible to linger in the stratosphere?
有可能在平流層停留嗎?
the stratosphere?
the stratosphere?
my favorite search engine
研究這件事
to call Taber MacCallum
Development Corporation,
we proceeded to do just that.
我們持續朝那個方向努力。
at speeds of up to 822 miles an hour.
and 27-second descent.
I opened a parachute and I landed.
我打開降落傘著陸。
and it's really an engineering talk,
是工程學演說,
about that experience
we can build a stratospheric suit,
我認為我們可以打造平流層服裝,
that formed the core of the group
which I think is important,
the analogy of scuba diving.
that you could ever need.
into the stratosphere.
that was made by ILC Dover.
所製的一套驚人服裝。
that made all of the Apollo suits
所有阿波羅計畫的太空裝,
activity suits.
都由他們出產。
which I am very grateful for.
讓我萬分感激。
This was all about safety.
安全是唯一考量。
and two small children --
and a reserve parachute,
和一個備用降落傘,
because of an automatic opening device.
就會開傘。
can protect me from the cold.
has thermal protection.
that will wrap around my body.
a quarter-inch hole in this suit,
from the low pressure of space.
不受到太空低壓傷害。
is weight and complexity.
在於重量和複雜度。
recently to go up in the stratosphere,
飛進平流層的裝置相比,
amount of complexity that goes into it,
to an altitude of 135,000 feet,
到 42 公里高,
that was 45 to 50 million cubic feet.
立方公尺的大氣球。
500 pounds in this system,
只有 227 公斤,
that was five times smaller than that,
氣球就夠了,
that was dramatically simpler
變得簡易許多,
for a much larger balloon.
to Roswell, New Mexico, on October 24.
新墨西哥州的羅斯威爾。
that got up in the middle of the night.
that you'll see in a second,
馬上你就會看到,
of the actual launch.
to launch balloons,
to land under a parachute,
70 miles away from the place you started.
110 公里外的地方降落。
and a half pre-breathing.
做預先呼吸純氧了。
air-conditioned van
but I got a front loader.
You can see the balloon up there.
with the FAA for 15 miles.
正在清空 24 公里的飛行空間。
is the emergency cutaway.
from using my right hand.
It's kind of like Google Earth in reverse.
有點像是反向的 Google 地球。
and seven minutes to go up,
two hours and seven minutes.
very much oxygen.
in the background
because if you look,
and I'm probably at 50,000 feet,
into a stratospheric wind
that I had just gone higher
顯示我剛超越
had ever gone in a balloon,
the curvature of the Earth,
地球的曲線,
mentally right now.
I want to be ready.
and stay completely stable.
going by, fully inflated at this point.
當時已經完全沒有氣了。
which I'll demonstrate in just a second,
我馬上會示範操作,
going by a second time.
at the speed of sound.
it's the speed of sound,
as fast as I ever get,
the parachute come out right there.
降落傘從那邊打開。
that there's a parachute out.
有個降落傘打開了。
was really happy as well.
is the moment I opened --
Blikkies, my parachute guy.
和我一起玩降落傘的夥伴。
and he actually jumped out
properly called a crash.
但稱墜地可能比較恰當。
even close to my worst landing.
我著陸最差的一次。
in that video,
of the entire thing was the release
就是那個釋放,
something called a drogue parachute,
was there to stabilize me.
gone tandem skydiving,
you're in zero gravity.
to just turn right around you.
you can be tangled up or spinning,
可能就已經被纏住或在旋轉了,
is you're going down at 800 miles an hour,
以近 1,300 公里的時速下降,
Technologies came up with this idea,
想出一個辦法,
and wrap it around,
然後繞著它轉,
it will ever tangle with you.
a very serious potential problem.
without an amazing team of people.
of this whole thing was,
最棒的部分是什麼,
to work with the best experts
and parachute technology
乘氣球飛行和降落傘技術、
and high altitude medicine.
to work with that group of people.
和那群人合作是工程師的夢想。
wanted to thank my friends at Google,
in the times that I was away.
I wanted to thank, and that's my family.
就是我的家人。
about the safety of technology,
跟他們說技術安全的事,
that my wife put up with it
after each of the 250 tests,
我每次回來心情都非常好,
to take that away from me.
she and I were in the car,
她和我在車上,
and she was sitting there,
"Dad, I've got this idea."
「爸,我有個想法。」
and I said, "Katelyn, that's impossible."
「凱特琳,這件事不可能。」
after what you just did,
"OK, it's not impossible,
and I said, "Katelyn,
it may not even be very, very hard,
也許不是非常、非常難,
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.
