KIDS: Our World!

00:00:16.233 --> 00:00:19.820
EVAN: Well Globey, it's been a
long day.

00:00:19.888 --> 00:00:23.531
Time to get some shut-eye.
My bed is so warm and cozy

00:00:23.533 --> 00:00:26.646
especially when my head hits
that pillow, but do you ever

00:00:26.648 --> 00:00:29.578
wonder what it would be like to
sleep in space?

00:00:32.751 --> 00:00:36.941
Well good morning. You all
really got an early start

00:00:36.943 --> 00:00:42.098
today. It's 6 am on board the
International Space station.

00:00:42.100 --> 00:00:46.260
I've just finished a good
night's sleep. We generally go

00:00:46.261 --> 00:00:50.913
to bed at about 9:30 at night,
so that gave me a nice 8 1/2

00:00:50.915 --> 00:00:54.361
hours of sleep. Anyhow, it's
great that you decided to join

00:00:54.363 --> 00:00:58.040
us so early. If you bear with
me just a little bit, I'll get

00:00:58.041 --> 00:01:04.041
out of my bed or my sleeping
bag and I'll give you a little

00:01:04.043 --> 00:01:07.871
bit of an introduction or a
little bit of a briefing on how

00:01:07.873 --> 00:01:11.216
we do things like sleep on
board the station.

00:01:12.438 --> 00:01:15.298
EVAN: Astronauts aboard the
International Space Station

00:01:15.300 --> 00:01:18.190
sleep in an area called a
Temporary Sleep Space

00:01:18.191 --> 00:01:22.450
or TESS for short. In the
reduced gravity environment of

00:01:22.451 --> 00:01:26.476
space, there is no up or down.
The astronauts who appear to be

00:01:26.478 --> 00:01:29.843
floating can actually use all
of the space around them.

00:01:29.845 --> 00:01:33.213
Astronauts can sleep in any
orientation, but they have to

00:01:33.215 --> 00:01:37.406
attach themselves to a wall, a
seat, or a bunk bed inside the

00:01:37.408 --> 00:01:40.181
crew cabin so they don't float
around and bump into something

00:01:40.183 --> 00:01:43.503
or each other.

00:01:43.505 --> 00:01:46.011
Astronauts are scheduled for 8
hours of sleep

00:01:46.013 --> 00:01:48.951
at the end of each mission day.
But just like sleeping here on

00:01:48.953 --> 00:01:52.018
Earth, astronauts can have
difficulty sleeping.

00:01:52.020 --> 00:01:55.750
Studies show that astronauts
typically sleep Ĺ an hour to

00:01:55.751 --> 00:01:59.745
2 Ĺ hours less than they do on
Earth. They may wake up to use

00:01:59.746 --> 00:02:03.148
the restroom or get a drink of
water. Some astronauts have

00:02:03.150 --> 00:02:06.795
even reporting snoring in
space. Other factors on board

00:02:06.796 --> 00:02:11.678
the ISS like noise and lights
can also interrupt sleep.

00:02:11.680 --> 00:02:14.533
As we go into TESS, the first
thing you see is my sleeping

00:02:14.535 --> 00:02:17.750
bag. And as you can see, my
sleeping bag is just kind of a

00:02:17.751 --> 00:02:20.843
normal sleeping bag. It's a
fabric cover. And I'll tell

00:02:20.845 --> 00:02:24.163
you a little bit more about it
shortly. In the back, you can

00:02:24.165 --> 00:02:26.770
see there, the headset that I
use when I want to make

00:02:26.771 --> 00:02:29.843
telephone calls to family or
friends or anyone for that

00:02:29.845 --> 00:02:33.718
matter. And there's my laptop
computer. I use that of course

00:02:33.720 --> 00:02:37.253
for all of the things you use a
computer for. I can read books

00:02:37.255 --> 00:02:40.656
on it, magazines, I watch
television, movies;

00:02:40.658 --> 00:02:43.673
it's really quite convenient.

00:02:43.675 --> 00:02:46.903
EVAN: That's like a little
space sleeping pod!

00:02:46.905 --> 00:02:50.066
Here's my sleeping bag. And of
course unlike my sleeping bag

00:02:50.068 --> 00:02:52.305
on Earth. With this one, I
don't have to lay it down to

00:02:52.306 --> 00:02:55.020
get into it. Some of the
unusual sort of space like

00:02:55.021 --> 00:02:57.951
features are that it has a
little slot for each arm to

00:02:57.953 --> 00:03:00.545
come out of. It serves a couple
of useful functions.

00:03:00.546 --> 00:03:02.915
Of course one of them is it
allows me to do work inside my

00:03:02.916 --> 00:03:05.536
little sleep station. It allows
me to work on the

00:03:05.538 --> 00:03:08.778
computer if I would like. Plus
also, if I get a little warm,

00:03:08.780 --> 00:03:12.331
it allows me to stay in the
sleeping bag and still be

00:03:12.333 --> 00:03:16.078
restrained, which is a
different function than our

00:03:16.080 --> 00:03:19.275
sleeping bag. A sleeping bag on
the ground really is just

00:03:19.276 --> 00:03:22.191
designed to keep you warm. This
is also designed to keep

00:03:22.193 --> 00:03:25.805
us from moving around so much.
We can secure it to the floor

00:03:25.806 --> 00:03:28.271
or the walls or the ceiling if
you really want to sleep

00:03:28.273 --> 00:03:30.626
in an unusual fashion.

00:03:30.628 --> 00:03:34.315
EVAN: Sleeping on the ceiling?
Now that's really a different

00:03:34.316 --> 00:03:36.850
way of getting some Zzzz's. I
wonder what it's like

00:03:36.851 --> 00:03:39.000
waking up like that?

00:03:39.001 --> 00:03:41.955
Getting ready for work first
means taking care of a few

00:03:41.956 --> 00:03:47.585
normal chores like brushing
your teeth. We do get asked

00:03:47.586 --> 00:03:51.036
very often Ďhow do you brush
your teeth in space' and what

00:03:51.038 --> 00:03:55.780
you do with the toothpaste.
Well, let me show you what we

00:03:55.781 --> 00:03:59.618
use to brush our teeth in
space. A tube of toothpaste.

00:03:59.620 --> 00:04:04.053
And a toothbrush. Just like the
ones you use. And I hope

00:04:04.055 --> 00:04:08.456
you brush your teeth 3 times a
day. Now, as I'm brushing my

00:04:08.458 --> 00:04:11.835
teeth. There's no sink to spit
in, so what do I do?

00:04:11.836 --> 00:04:16.875
Use a towel? This is a package
that has one dry towel in it.

00:04:16.876 --> 00:04:20.245
This is provided by Russian
space program and it works as

00:04:20.246 --> 00:04:23.486
very nice little towels.
And yes, almost everything has

00:04:23.488 --> 00:04:27.121
Velcro on it. I can either
swallow the toothpaste or I can

00:04:27.123 --> 00:04:31.036
spit it into the towel.
Unfortunately one other chore

00:04:31.038 --> 00:04:33.760
that I have to deal with
everyday is shaving.

00:04:33.761 --> 00:04:37.990
So, I use something called
Astro Edge Shaving Cream.

00:04:37.991 --> 00:04:40.871
And a razor just like I would
on the ground.

00:04:40.873 --> 00:04:43.983
Again, no running water. So,
it's difficult to clean my

00:04:43.985 --> 00:04:47.145
razor, so I just use the same
old towel. This means I would

00:04:47.146 --> 00:04:49.928
have to replace the blade a
little more frequently than I

00:04:49.930 --> 00:04:54.223
would on the Earth. No running
water. How do I get all that

00:04:54.225 --> 00:04:57.813
extra soap off my face?
Courtesy of the Russian space

00:04:57.815 --> 00:05:01.243
program, we have these
wonderful wet towels.

00:05:01.245 --> 00:05:04.640
Each package has one wet towel
in it. And there I am.

00:05:04.708 --> 00:05:08.008
I've brushed my teeth. I've
shaved. I've washed my face.

00:05:08.078 --> 00:05:10.945
Now I'm ready to go have
breakfast.

00:05:11.013 --> 00:05:14.481
And remember, every
day ought to start out with a

00:05:14.550 --> 00:05:19.408
good healthy breakfast. And
follow that up by two other

00:05:19.410 --> 00:05:23.221
well balanced meals throughout
the rest of the day.

00:05:23.223 --> 00:05:26.238
And you'll be able to do lot's
of other good work whether it's

00:05:26.240 --> 00:05:28.830
at school or on board the
International Space Station.

00:05:28.831 --> 00:05:31.323
Have a great day.

00:05:31.325 --> 00:05:33.633
EVAN: So the next time you're
getting ready to start your

00:05:33.635 --> 00:05:36.001
day, think about the astronauts
on the International Space

00:05:36.070 --> 00:05:39.340
Station. But don't swallow your
toothpaste.
