0:00:00.730,0:00:02.142
I'm an astronaut.

0:00:02.659,0:00:04.920
I flew on the space shuttle twice,

0:00:04.944,0:00:09.271
and I lived on the International[br]Space Station for almost six months.

0:00:09.295,0:00:15.032
People often ask me the same question,[br]which is, "What's it like in space?"

0:00:15.056,0:00:16.835
as if it was a secret.

0:00:16.859,0:00:19.116
Space belongs to all of us,

0:00:19.140,0:00:25.865
and I'd like to help you understand why[br]it's a place that is magic for all of us.

0:00:26.402,0:00:29.642
The day after my 50th birthday,

0:00:29.666,0:00:33.164
I climbed aboard a Russian capsule,

0:00:33.188,0:00:34.561
in Russia,

0:00:34.585,0:00:36.698
and launched into space.

0:00:37.110,0:00:40.506
Launching is the most[br]dangerous thing that we do,

0:00:40.530,0:00:42.405
and it's also the most thrilling.

0:00:43.214,0:00:46.801
Three, two, one ... liftoff!

0:00:46.825,0:00:51.987
I felt every single bit of the controlled[br]fury of those rocket engines

0:00:52.011,0:00:54.774
as they blasted us off the Earth.

0:00:55.260,0:00:58.172
We went faster and faster and faster,

0:00:58.196,0:01:03.347
until, after eight and a half minutes,[br]on purpose, those engines stop --

0:01:03.979,0:01:05.204
kabunk! --

0:01:05.228,0:01:07.386
and we are weightless.

0:01:07.410,0:01:10.806
And the mission and the magic begin.

0:01:11.174,0:01:14.516
Dmitry and Paolo and I[br]are circling the Earth

0:01:14.540,0:01:16.365
in our tiny spacecraft,

0:01:16.389,0:01:18.873
approaching the space station carefully.

0:01:19.309,0:01:23.647
It's an intricate dance[br]at 17,500 miles an hour

0:01:23.671,0:01:27.427
between our capsule,[br]the size of a Smart Car,

0:01:27.451,0:01:30.838
and the space station,[br]the size of a football field.

0:01:30.862,0:01:37.577
We arrive when those two craft dock[br]with a gentle thunk.

0:01:38.405,0:01:40.596
We open the hatches,

0:01:40.620,0:01:44.114
have sloppy zero-G hugs with each other,

0:01:44.138,0:01:46.367
and now we're six.

0:01:46.391,0:01:49.444
We're a space family, an instant family.

0:01:50.618,0:01:53.911
My favorite part about living up there

0:01:53.935,0:01:55.623
was the flying.

0:01:56.266,0:01:57.420
I loved it.

0:01:57.444,0:01:59.174
It was like being Peter Pan.

0:01:59.198,0:02:00.598
It's not about floating.

0:02:00.622,0:02:02.558
Just the touch of a finger

0:02:02.582,0:02:06.357
can actually push you across[br]the entire space station,

0:02:06.381,0:02:09.122
and then you sort of[br]tuck in with your toes.

0:02:09.146,0:02:13.331
One of my favorite things[br]was drifting silently

0:02:13.355,0:02:14.745
through the space station,

0:02:14.769,0:02:16.914
which was humming along at night.

0:02:16.938,0:02:20.447
I wondered sometimes[br]if it knew I was there,

0:02:20.471,0:02:22.035
just silent.

0:02:22.059,0:02:25.579
But sharing the wonder[br]of that with the crew

0:02:25.603,0:02:28.645
was also part of what was important to me.

0:02:30.394,0:02:36.277
A typical day in space[br]starts with the perfect commute.

0:02:36.301,0:02:39.424
I wake up, cruise down the lab

0:02:39.448,0:02:43.463
and say hello to the best[br]morning view ever.

0:02:43.880,0:02:48.525
It's a really fast commute,[br]only 30 seconds,

0:02:48.549,0:02:51.038
and we never get tired[br]of looking out that window.

0:02:51.062,0:02:55.852
I think it reminds us that we're[br]actually still very close to Earth.

0:02:56.426,0:03:00.104
Our crew was the second ever[br]to use the Canadian robotic arm

0:03:00.128,0:03:03.721
to capture a supply ship[br]the size of a school bus

0:03:03.745,0:03:06.469
containing about a dozen[br]different experiments

0:03:06.493,0:03:10.494
and the only chocolate that we would see[br]for the next four months.

0:03:10.518,0:03:13.552
Now, chocolate aside,[br]every single one of those experiments

0:03:13.576,0:03:17.829
enables yet one more[br]scientific question answered

0:03:17.853,0:03:21.086
that we can't do down here on Earth.

0:03:21.110,0:03:23.468
And so, it's like a different lens,

0:03:23.492,0:03:26.500
allowing us to see the answers[br]to questions like,

0:03:26.524,0:03:27.736
"What about combustion?"

0:03:27.760,0:03:30.609
"What about fluid dynamics?"

0:03:30.633,0:03:33.232
Now, sleeping is delightful.

0:03:33.256,0:03:36.364
My favorite -- I mean, you could be[br]upside down, right side up --

0:03:36.388,0:03:39.360
my favorite: curled up[br]in a little ball and floating freely.

0:03:40.066,0:03:42.335
Laundry? Nope.

0:03:42.359,0:03:45.987
We load our dirty clothes[br]into an empty supply ship

0:03:46.011,0:03:48.276
and send it off into space.

0:03:48.300,0:03:49.471
The bathroom.

0:03:49.495,0:03:50.887
Everyone wants to know.

0:03:50.911,0:03:53.635
It's hard to understand,[br]so I made a little video,

0:03:53.659,0:03:56.119
because I wanted kids to understand

0:03:56.143,0:03:59.040
that the principle of vacuum saves the day

0:03:59.064,0:04:02.143
and that just a gentle breeze[br]helps everything go

0:04:02.167,0:04:04.380
where it is supposed to.

0:04:04.404,0:04:06.303
Well, in real life it does.

0:04:06.327,0:04:07.405
(Laughter)

0:04:07.429,0:04:08.620
Recycling? Of course.

0:04:08.644,0:04:13.891
So we take our urine, we store it,[br]we filter it and then we drink it.

0:04:13.915,0:04:15.450
And it's actually delicious.

0:04:15.474,0:04:16.489
(Laughter)

0:04:16.513,0:04:18.635
Sitting around the table,

0:04:18.659,0:04:21.481
eating food that looks bad[br]but actually tastes pretty good.

0:04:21.505,0:04:24.319
But it's the gathering around[br]the table that's important,

0:04:24.343,0:04:27.619
I think both in space and on Earth,

0:04:27.643,0:04:30.374
because that's what cements[br]a crew together.

0:04:31.032,0:04:34.733
For me, music was a way to stay connected[br]to the rest of the world.

0:04:34.757,0:04:37.995
I played a duet between Earth and space

0:04:38.019,0:04:40.965
with Ian Anderson of Jethro Tull

0:04:40.989,0:04:44.080
on the 50th anniversary[br]of human spaceflight.

0:04:44.644,0:04:47.199
Connecting to family was so important.

0:04:47.223,0:04:51.533
I talked with my family almost every day[br]the whole time I was up there,

0:04:51.557,0:04:56.608
and I would actually read books to my son[br]as a way for us just to be together.

0:04:56.632,0:04:57.923
So important.

0:04:57.947,0:05:00.593
Now, when the space station[br]would go over Massachusetts,

0:05:00.617,0:05:02.266
my family would run outside,

0:05:02.290,0:05:06.956
and they would watch the brightest star[br]sailing across the sky.

0:05:06.980,0:05:09.629
And when I looked down,[br]I couldn't see my house,

0:05:09.653,0:05:13.576
but it meant a lot to me to know[br]that the people I loved the most

0:05:13.600,0:05:16.580
were looking up while I was looking down.

0:05:17.160,0:05:22.952
So the space station, for me, is the place[br]where mission and magic come together.

0:05:22.976,0:05:25.606
The mission, the work are vital steps

0:05:25.630,0:05:27.856
in our quest to go further than our planet

0:05:27.880,0:05:31.951
and imperative for understanding[br]sustainability here on Earth.

0:05:31.975,0:05:33.693
I loved being a part of that,

0:05:33.717,0:05:36.493
and if I could have taken[br]my family with me,

0:05:36.517,0:05:38.279
I never would have come home.

0:05:38.853,0:05:42.044
And so my view from the station showed me

0:05:42.068,0:05:45.160
that we are all from the same place.

0:05:45.184,0:05:48.112
We all have our roles to play.

0:05:48.136,0:05:51.699
Because, the Earth is our ship.

0:05:51.723,0:05:54.237
Space is our home.

0:05:55.086,0:05:59.671
And we are the crew of Spaceship Earth.

0:06:00.687,0:06:01.864
Thank you.

0:06:01.888,0:06:03.439
(Applause)
