00:00:11,340 --> 00:00:14,651
KIDS: Our World!

3
00:00:16,233 --> 00:00:19,820
EVAN: Well Globey, it’s been a
long day.

4
00:00:19,888 --> 00:00:23,531
Time to get some shut-eye.
My bed is so warm and cozy

5
00:00:23,533 --> 00:00:26,646
especially when my head hits
that pillow, but do you ever

6
00:00:26,648 --> 00:00:29,578
wonder what it would be like to
sleep in space?

7
00:00:32,751 --> 00:00:36,941
Well good morning. You all
really got an early start

8
00:00:36,943 --> 00:00:42,098
today. It’s 6 am on board the
International Space station.

9
00:00:42,100 --> 00:00:46,260
I’ve just finished a good
night’s sleep. We generally go

10
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

11
00:00:50,915 --> 00:00:54,361
hours of sleep. Anyhow, it’s
great that you decided to join

12
00:00:54,363 --> 00:00:58,040
us so early. If you bear with
me just a little bit, I’ll get

13
00:00:58,041 --> 00:01:04,041
out of my bed or my sleeping
bag and I’ll give you a little

14
00:01:04,043 --> 00:01:07,871
bit of an introduction or a
little bit of a briefing on how

15
00:01:07,873 --> 00:01:11,216
we do things like sleep on
board the station.

16
00:01:12,438 --> 00:01:15,298
EVAN: Astronauts aboard the
International Space Station

17
00:01:15,300 --> 00:01:18,190
sleep in an area called a
Temporary Sleep Space

18
00:01:18,191 --> 00:01:22,450
or TESS for short. In the
reduced gravity environment of

19
00:01:22,451 --> 00:01:26,476
space, there is no up or down.
The astronauts who appear to be

20
00:01:26,478 --> 00:01:29,843
floating can actually use all
of the space around them.

21
00:01:29,845 --> 00:01:33,213
Astronauts can sleep in any
orientation, but they have to

22
00:01:33,215 --> 00:01:37,406
attach themselves to a wall, a
seat, or a bunk bed inside the

23
00:01:37,408 --> 00:01:40,181
crew cabin so they don't float
around and bump into something

24
00:01:40,183 --> 00:01:43,503
or each other.

25
00:01:43,505 --> 00:01:46,011
Astronauts are scheduled for 8
hours of sleep

26
00:01:46,013 --> 00:01:48,951
at the end of each mission day.
But just like sleeping here on

27
00:01:48,953 --> 00:01:52,018
Earth, astronauts can have
difficulty sleeping.

28
00:01:52,020 --> 00:01:55,750
Studies show that astronauts
typically sleep ½ an hour to

29
00:01:55,751 --> 00:01:59,745
2 ½ hours less than they do on
Earth. They may wake up to use

30
00:01:59,746 --> 00:02:03,148
the restroom or get a drink of
water. Some astronauts have

31
00:02:03,150 --> 00:02:06,795
even reporting snoring in
space. Other factors on board

32
00:02:06,796 --> 00:02:11,678
the ISS like noise and lights
can also interrupt sleep.

33
00:02:11,680 --> 00:02:14,533
As we go into TESS, the first
thing you see is my sleeping

34
00:02:14,535 --> 00:02:17,750
bag. And as you can see, my
sleeping bag is just kind of a

35
00:02:17,751 --> 00:02:20,843
normal sleeping bag. It’s a
fabric cover. And I’ll tell

36
00:02:20,845 --> 00:02:24,163
you a little bit more about it
shortly. In the back, you can

37
00:02:24,165 --> 00:02:26,770
see there, the headset that I
use when I want to make

38
00:02:26,771 --> 00:02:29,843
telephone calls to family or
friends or anyone for that

39
00:02:29,845 --> 00:02:33,718
matter. And there’s my laptop
computer. I use that of course

40
00:02:33,720 --> 00:02:37,253
for all of the things you use a
computer for. I can read books

41
00:02:37,255 --> 00:02:40,656
on it, magazines, I watch
television, movies;

42
00:02:40,658 --> 00:02:43,673
it’s really quite convenient.

43
00:02:43,675 --> 00:02:46,903
EVAN: That’s like a little
space sleeping pod!

44
00:02:46,905 --> 00:02:50,066
Here’s my sleeping bag. And of
course unlike my sleeping bag

45
00:02:50,068 --> 00:02:52,305
on Earth. With this one, I
don’t have to lay it down to

46
00:02:52,306 --> 00:02:55,020
get into it. Some of the
unusual sort of space like

47
00:02:55,021 --> 00:02:57,951
features are that it has a
little slot for each arm to

48
00:02:57,953 --> 00:03:00,545
come out of. It serves a couple
of useful functions.

49
00:03:00,546 --> 00:03:02,915
Of course one of them is it
allows me to do work inside my

50
00:03:02,916 --> 00:03:05,536
little sleep station. It allows
me to work on the

51
00:03:05,538 --> 00:03:08,778
computer if I would like. Plus
also, if I get a little warm,

52
00:03:08,780 --> 00:03:12,331
it allows me to stay in the
sleeping bag and still be

53
00:03:12,333 --> 00:03:16,078
restrained, which is a
different function than our

54
00:03:16,080 --> 00:03:19,275
sleeping bag. A sleeping bag on
the ground really is just

55
00:03:19,276 --> 00:03:22,191
designed to keep you warm. This
is also designed to keep

56
00:03:22,193 --> 00:03:25,805
us from moving around so much.
We can secure it to the floor

57
00:03:25,806 --> 00:03:28,271
or the walls or the ceiling if
you really want to sleep

58
00:03:28,273 --> 00:03:30,626
in an unusual fashion.

59
00:03:30,628 --> 00:03:34,315
EVAN: Sleeping on the ceiling?
Now that’s really a different

60
00:03:34,316 --> 00:03:36,850
way of getting some Zzzz’s. I
wonder what it’s like

61
00:03:36,851 --> 00:03:39,000
waking up like that?

62
00:03:39,001 --> 00:03:41,955
Getting ready for work first
means taking care of a few

63
00:03:41,956 --> 00:03:47,585
normal chores like brushing
your teeth. We do get asked

64
00:03:47,586 --> 00:03:51,036
very often ‘how do you brush
your teeth in space’ and what

65
00:03:51,038 --> 00:03:55,780
you do with the toothpaste.
Well, let me show you what we

66
00:03:55,781 --> 00:03:59,618
use to brush our teeth in
space. A tube of toothpaste.

67
00:03:59,620 --> 00:04:04,053
And a toothbrush. Just like the
ones you use. And I hope

68
00:04:04,055 --> 00:04:08,456
you brush your teeth 3 times a
day. Now, as I’m brushing my

69
00:04:08,458 --> 00:04:11,835
teeth. There’s no sink to spit
in, so what do I do?

70
00:04:11,836 --> 00:04:16,875
Use a towel? This is a package
that has one dry towel in it.

71
00:04:16,876 --> 00:04:20,245
This is provided by Russian
space program and it works as

72
00:04:20,246 --> 00:04:23,486
very nice little towels.
And yes, almost everything has

73
00:04:23,488 --> 00:04:27,121
Velcro on it. I can either
swallow the toothpaste or I can

74
00:04:27,123 --> 00:04:31,036
spit it into the towel.
Unfortunately one other chore

75
00:04:31,038 --> 00:04:33,760
that I have to deal with
everyday is shaving.

76
00:04:33,761 --> 00:04:37,990
So, I use something called
Astro Edge Shaving Cream.

77
00:04:37,991 --> 00:04:40,871
And a razor just like I would
on the ground.

78
00:04:40,873 --> 00:04:43,983
Again, no running water. So,
it’s difficult to clean my

79
00:04:43,985 --> 00:04:47,145
razor, so I just use the same
old towel. This means I would

80
00:04:47,146 --> 00:04:49,928
have to replace the blade a
little more frequently than I

81
00:04:49,930 --> 00:04:54,223
would on the Earth. No running
water. How do I get all that

82
00:04:54,225 --> 00:04:57,813
extra soap off my face?
Courtesy of the Russian space

83
00:04:57,815 --> 00:05:01,243
program, we have these
wonderful wet towels.

84
00:05:01,245 --> 00:05:04,640
Each package has one wet towel
in it. And there I am.

85
00:05:04,708 --> 00:05:08,008
I've brushed my teeth. I’ve
shaved. I’ve washed my face.

86
00:05:08,078 --> 00:05:10,945
Now I'm ready to go have
breakfast.

87
00:05:11,013 --> 00:05:14,481
And remember, every
day ought to start out with a

88
00:05:14,550 --> 00:05:19,408
good healthy breakfast. And
follow that up by two other

89
00:05:19,410 --> 00:05:23,221
well balanced meals throughout
the rest of the day.

90
00:05:23,223 --> 00:05:26,238
And you’ll be able to do lot’s
of other good work whether it’s

91
00:05:26,240 --> 00:05:28,830
at school or on board the
International Space Station.

92
00:05:28,831 --> 00:05:31,323
Have a great day.

93
00:05:31,325 --> 00:05:33,633
EVAN: So the next time you’re
getting ready to start your

94
00:05:33,635 --> 00:05:36,001
day, think about the astronauts
on the International Space

95
00:05:36,070 --> 00:05:39,340
Station. But don’t swallow your
toothpaste.
