1
00:00:07,510 --> 00:00:04,710
i'm don pettit i'm a nasa astronaut and

2
00:00:11,270 --> 00:00:07,520
i'm on the international space station

3
00:00:13,270 --> 00:00:11,280
we're currently about 240

4
00:00:19,429 --> 00:00:13,280
nautical miles above the surface of

5
00:00:19,439 --> 00:00:45,990
do

6
00:00:50,389 --> 00:00:48,709
space station is a serious place

7
00:00:53,670 --> 00:00:50,399
we're doing

8
00:00:56,229 --> 00:00:53,680
serious research scientific research and

9
00:00:58,549 --> 00:00:56,239
engineering research we have a

10
00:01:00,950 --> 00:00:58,559
regenerative life support system which

11
00:01:03,590 --> 00:01:00,960
is a fancy way of saying that we've got

12
00:01:05,030 --> 00:01:03,600
a toilet that you use and then a machine

13
00:01:06,710 --> 00:01:05,040
that goes chugga chugga chugga chugga

14
00:01:08,950 --> 00:01:06,720
chug and then you go to the galley and

15
00:01:10,550 --> 00:01:08,960
you make yourself a cup of coffee and

16
00:01:12,870 --> 00:01:10,560
that's exactly

17
00:01:14,469 --> 00:01:12,880
what you are thinking it is and this is

18
00:01:16,870 --> 00:01:14,479
the kind of engineering research that

19
00:01:19,030 --> 00:01:16,880
we're doing on space station it's needed

20
00:01:21,350 --> 00:01:19,040
so that when we go to mars we won't run

21
00:01:22,870 --> 00:01:21,360
out of water and of course

22
00:01:24,469 --> 00:01:22,880
not only would you have angry birds if

23
00:01:26,950 --> 00:01:24,479
you ran out of water you'd have angry

24
00:01:30,390 --> 00:01:26,960
human beings too

25
00:01:32,630 --> 00:01:30,400
i want to do some physics demonstrations

26
00:01:35,670 --> 00:01:32,640
that involve some of the things you

27
00:01:38,069 --> 00:01:35,680
might see in the angry birds game and of

28
00:01:42,630 --> 00:01:38,079
course i've got my angry bird here but

29
00:01:45,670 --> 00:01:43,670
well

30
00:01:47,830 --> 00:01:45,680
i'm not very good at art it's a good

31
00:01:49,670 --> 00:01:47,840
thing i decided to be a scientist and an

32
00:01:52,789 --> 00:01:49,680
engineer instead of an artist because

33
00:01:55,590 --> 00:01:52,799
i'd probably be starving by now

34
00:01:58,389 --> 00:01:55,600
okay here here is pig

35
00:01:59,990 --> 00:01:58,399
and of course pig is the arch enemy of

36
00:02:03,670 --> 00:02:00,000
angry bird

37
00:02:03,680 --> 00:02:06,709
some eggs

38
00:02:11,589 --> 00:02:09,830
add pig

39
00:02:14,150 --> 00:02:11,599
stole the eggs

40
00:02:16,390 --> 00:02:14,160
and don't ask me how i got the eggs on

41
00:02:19,110 --> 00:02:16,400
space station

42
00:02:20,630 --> 00:02:19,120
i've got a bungee spread across the

43
00:02:22,710 --> 00:02:20,640
hatch way

44
00:02:24,070 --> 00:02:22,720
and this bun jeep is kind of like a

45
00:02:27,030 --> 00:02:24,080
slingshot

46
00:02:29,990 --> 00:02:27,040
and i'm going to show the trajectory

47
00:02:34,550 --> 00:02:30,000
that red bird is going to have when i

48
00:02:38,390 --> 00:02:34,560
fire him with this orbital slingshot

49
00:02:41,030 --> 00:02:38,400
launching red bird into space well hey

50
00:02:42,949 --> 00:02:41,040
we're already in the space

51
00:02:45,270 --> 00:02:42,959
whoa look at that

52
00:02:47,190 --> 00:02:45,280
all the way down

53
00:02:50,550 --> 00:02:47,200
that's an example of a trajectory it's a

54
00:02:53,030 --> 00:02:50,560
straight line from our perspective here

55
00:02:54,710 --> 00:02:53,040
gravity will attract an object if it's

56
00:02:56,550 --> 00:02:54,720
moving in a straight line and it will no

57
00:03:00,470 --> 00:02:56,560
longer move in a straight line it gets

58
00:03:03,110 --> 00:03:00,480
bent and it goes in a curved trajectory

59
00:03:04,470 --> 00:03:03,120
and guess what astronauts have to worry

60
00:03:06,790 --> 00:03:04,480
about these things because if you're in

61
00:03:07,830 --> 00:03:06,800
a rocket and say you're trying to get

62
00:03:10,630 --> 00:03:07,840
from

63
00:03:13,430 --> 00:03:10,640
one orbit and rendezvous space station

64
00:03:14,949 --> 00:03:13,440
you end up going in curved trajectories

65
00:03:16,949 --> 00:03:14,959
and you need to know how to fire your

66
00:03:20,149 --> 00:03:16,959
rocket engines so that you can go from

67
00:03:22,070 --> 00:03:20,159
where you are to where you want to be

68
00:03:23,910 --> 00:03:22,080
and if you understand the math if you

69
00:03:26,869 --> 00:03:23,920
understand the physics

70
00:03:31,030 --> 00:03:26,879
it will allow you to go out and get a

71
00:03:32,869 --> 00:03:31,040
neat job a job sort of like mine where

72
00:03:33,990 --> 00:03:32,879
you're an astronaut and you can fly in

73
00:03:36,789 --> 00:03:34,000
space

74
00:03:38,470 --> 00:03:36,799
learn about these subjects in school you

75
00:03:41,030 --> 00:03:38,480
can also learn about these subjects

76
00:03:43,589 --> 00:03:41,040
while you're playing games

77
00:03:46,710 --> 00:03:43,599
what happens when

78
00:03:49,589 --> 00:03:46,720
something like an angry bird

79
00:03:50,789 --> 00:03:49,599
gets their eggs stolen

80
00:03:51,830 --> 00:03:50,799
by

81
00:03:56,309 --> 00:03:51,840
pig

82
00:03:58,390 --> 00:03:56,319
got exploded

83
00:04:02,070 --> 00:03:58,400
and we got to see all of this in a

84
00:04:04,390 --> 00:04:02,080
weightless environment which is what the

85
00:04:07,910 --> 00:04:04,400
angry bird space game is going to be
