1
00:00:01,360 --> 00:00:05,190
houston station on two

2
00:00:11,430 --> 00:00:09,430
okay so i hit pause um we have

3
00:00:13,270 --> 00:00:11,440
one of our cameras that was specially

4
00:00:15,990 --> 00:00:13,280
modified and flown up

5
00:00:18,070 --> 00:00:16,000
with us for this expedition where the

6
00:00:20,870 --> 00:00:18,080
infrared blocking filter has been

7
00:00:23,349 --> 00:00:20,880
removed so this camera is sensitive to

8
00:00:25,509 --> 00:00:23,359
the near infrared region of the spectrum

9
00:00:27,509 --> 00:00:25,519
and here you see the infrared camera on

10
00:00:29,830 --> 00:00:27,519
top and mounted

11
00:00:33,110 --> 00:00:29,840
underneath it is a standard camera

12
00:00:36,310 --> 00:00:33,120
that's uh unmodified and we can take

13
00:00:37,910 --> 00:00:36,320
pictures now simultaneously of the same

14
00:00:40,150 --> 00:00:37,920
area so here's

15
00:00:41,190 --> 00:00:40,160
images cycling back and forth between

16
00:00:44,389 --> 00:00:41,200
visible

17
00:00:46,709 --> 00:00:44,399
and infrared and you can see

18
00:00:49,830 --> 00:00:46,719
the infrared part of the spectrum shows

19
00:00:51,990 --> 00:00:49,840
up in different shades of of red

20
00:00:54,389 --> 00:00:52,000
and and then the rest of the colors are

21
00:00:56,549 --> 00:00:54,399
pushed off into the the

22
00:00:57,590 --> 00:00:56,559
green and the blue channels on the

23
00:01:00,470 --> 00:00:57,600
camera

24
00:01:03,189 --> 00:01:00,480
and one of the aspects of infrared

25
00:01:05,429 --> 00:01:03,199
imagery is that it shows up agriculture

26
00:01:08,230 --> 00:01:05,439
in a in a very interesting way in more

27
00:01:10,789 --> 00:01:08,240
of a technical way and and it allows you

28
00:01:13,109 --> 00:01:10,799
to investigate more into the health of

29
00:01:15,670 --> 00:01:13,119
the crops and what's going on

30
00:01:17,510 --> 00:01:15,680
this is in the salton sea area

31
00:01:19,749 --> 00:01:17,520
in uh in

32
00:01:22,630 --> 00:01:19,759
california and you can see a little uh

33
00:01:24,950 --> 00:01:22,640
evaporative pond region in the sort of

34
00:01:27,429 --> 00:01:24,960
the center section

35
00:01:29,510 --> 00:01:27,439
here's how it looks in the infrared

36
00:01:31,109 --> 00:01:29,520
so again wherever there's plants you see

37
00:01:34,069 --> 00:01:31,119
bright red

38
00:01:36,390 --> 00:01:34,079
so the earth observation scientists will

39
00:01:39,190 --> 00:01:36,400
be able to take these kinds of images

40
00:01:40,469 --> 00:01:39,200
and compare directly the visible with

41
00:01:41,990 --> 00:01:40,479
the infrared

42
00:01:45,510 --> 00:01:42,000
where human beings make their cities

43
00:01:47,590 --> 00:01:45,520
it's primarily gray in the infrared

44
00:01:51,670 --> 00:01:47,600
you can see there's agriculture around

45
00:01:55,190 --> 00:01:51,680
these city regions this is visible

46
00:01:58,870 --> 00:01:57,910
now this is in all of our desert region

47
00:02:02,630 --> 00:01:58,880
in

48
00:02:04,310 --> 00:02:02,640
a little skip of snow on them you can

49
00:02:07,190 --> 00:02:04,320
see that to the

50
00:02:08,949 --> 00:02:07,200
to the left running north and south

51
00:02:10,949 --> 00:02:08,959
and in all of our desert region

52
00:02:13,110 --> 00:02:10,959
indivisible it just looks like a bunch

53
00:02:15,910 --> 00:02:13,120
of desert brown well one of the neat

54
00:02:18,550 --> 00:02:15,920
things about infrared is that water

55
00:02:20,949 --> 00:02:18,560
reflects infrared differently so here's

56
00:02:23,030 --> 00:02:20,959
the same oliver desert region in

57
00:02:25,510 --> 00:02:23,040
infrared and notice that one section

58
00:02:28,869 --> 00:02:25,520
that just looked like dry brown desert

59
00:02:30,630 --> 00:02:28,879
actually is freestanding water

60
00:02:32,550 --> 00:02:30,640
we even have some experiments on space

61
00:02:35,830 --> 00:02:32,560
station where we're imaging croplands in

62
00:02:38,309 --> 00:02:35,840
the united states and it's typically

63
00:02:40,229 --> 00:02:38,319
put on hold during the winter because we

64
00:02:42,710 --> 00:02:40,239
don't raise many crops during the winter

65
00:02:44,309 --> 00:02:42,720
but what i'm finding is you take

66
00:02:46,550 --> 00:02:44,319
infrared imagery

67
00:02:47,990 --> 00:02:46,560
of snow-covered scenes particularly with

68
00:02:50,710 --> 00:02:48,000
ice

69
00:02:52,390 --> 00:02:50,720
covered lakes and you can see some

70
00:02:57,990 --> 00:02:52,400
interesting detail that starts to show

71
00:02:58,000 --> 00:03:03,509
and here here is the infrared

72
00:03:08,229 --> 00:03:04,869
oh

73
00:03:10,470 --> 00:03:08,239
this is los angeles in the visible and

74
00:03:15,190 --> 00:03:10,480
you can see it's primarily gray

75
00:03:19,430 --> 00:03:16,949
and here it is in the infrared and

76
00:03:21,589 --> 00:03:19,440
notice the parts and the reserves show

77
00:03:24,470 --> 00:03:21,599
up quite well in the infrared you can

78
00:03:26,630 --> 00:03:24,480
see where there is lots of greenness

79
00:03:32,070 --> 00:03:26,640
in the los angeles region

80
00:03:34,710 --> 00:03:33,830
this is

81
00:03:40,229 --> 00:03:34,720
is

82
00:03:44,470 --> 00:03:40,239
and you can see the border between san

83
00:03:49,750 --> 00:03:46,710
and here it is in the infrared

84
00:03:52,630 --> 00:03:49,760
uh borders visible the cities are

85
00:03:55,350 --> 00:03:52,640
visible but all the the greeneries

86
00:03:58,710 --> 00:03:55,360
within the city show up quite clearly in

87
00:04:03,429 --> 00:04:00,789
so we're going to take a peek at some oh

88
00:04:04,789 --> 00:04:03,439
that's a very various cities now this

89
00:04:09,429 --> 00:04:04,799
this is

90
00:04:12,630 --> 00:04:09,439
in the amazon region if you take a

91
00:04:15,990 --> 00:04:12,640
visible picture of this area it looks

92
00:04:17,749 --> 00:04:16,000
kind of a misty foggy blue just because

93
00:04:19,830 --> 00:04:17,759
of the water vapor and the haze and the

94
00:04:22,390 --> 00:04:19,840
clouds and the infrared tends to cut

95
00:04:24,629 --> 00:04:22,400
through that and you can see the detail

96
00:04:30,629 --> 00:04:24,639
and the structure of the jungle canopies

97
00:04:36,150 --> 00:04:33,670
now this is a region in africa a jungle

98
00:04:38,469 --> 00:04:36,160
region and you can see in this visible

99
00:04:41,830 --> 00:04:38,479
picture where the jungles have been

100
00:04:43,430 --> 00:04:41,840
cleared for agricultural

101
00:04:45,990 --> 00:04:43,440
this is the

102
00:04:49,030 --> 00:04:46,000
ganges river delta there's a reserve

103
00:04:52,310 --> 00:04:49,040
there and this is lush mangrove jungle

104
00:04:54,870 --> 00:04:52,320
and you can see again it's bright red

105
00:04:56,629 --> 00:04:54,880
lots of greenery down there but look on

106
00:04:58,230 --> 00:04:56,639
the left-hand edge you can see that

107
00:04:59,830 --> 00:04:58,240
there's

108
00:05:01,029 --> 00:04:59,840
some sections there that aren't quite as

109
00:05:03,029 --> 00:05:01,039
red

110
00:05:05,110 --> 00:05:03,039
and we'll find out why

111
00:05:08,070 --> 00:05:05,120
this is another region in

112
00:05:11,510 --> 00:05:08,080
the ganges river delta in india and you

113
00:05:12,550 --> 00:05:11,520
can see where the reserves are

114
00:05:19,430 --> 00:05:12,560
where

115
00:05:23,110 --> 00:05:19,440
you can see in between there there are

116
00:05:26,150 --> 00:05:23,120
rows of mangroves

117
00:05:28,629 --> 00:05:26,160
and this this is a one of my favorites

118
00:05:29,510 --> 00:05:28,639
this is an oblique view of guatemala

119
00:05:32,230 --> 00:05:29,520
showing

120
00:05:35,029 --> 00:05:32,240
the jungle region with volcanoes popping

121
00:05:37,909 --> 00:05:35,039
up out of the area

122
00:05:39,350 --> 00:05:37,919
and this is along somewhere along the

123
00:05:42,310 --> 00:05:39,360
western

124
00:05:45,270 --> 00:05:42,320
coast of south america

125
00:05:46,870 --> 00:05:45,280
in chile there's some regions where the

126
00:05:48,870 --> 00:05:46,880
mountains come right up to the edge of

127
00:05:50,550 --> 00:05:48,880
the ocean and there's not a lot of plant

128
00:05:53,110 --> 00:05:50,560
material there as you can see the

129
00:05:55,590 --> 00:05:53,120
mountains are basically gray but there's

130
00:05:57,990 --> 00:05:55,600
a little river delta and

131
00:06:00,950 --> 00:05:58,000
lots of vegetation on this river delta

132
00:06:03,110 --> 00:06:00,960
shows up quite well in the infrared

133
00:06:04,550 --> 00:06:03,120
this is in japan i haven't quite

134
00:06:07,350 --> 00:06:04,560
identified it i'm not sure which

135
00:06:08,070 --> 00:06:07,360
volcanoes these are in japan but you can

136
00:06:11,189 --> 00:06:08,080
see

137
00:06:13,189 --> 00:06:11,199
the cities around the volcano regions

138
00:06:15,909 --> 00:06:13,199
where the snow-capped mountain there you

139
00:06:18,790 --> 00:06:15,919
can see where the plants are and where

140
00:06:22,309 --> 00:06:18,800
the cities are

141
00:06:24,710 --> 00:06:22,319
and this is tokyo and again typifies

142
00:06:28,309 --> 00:06:24,720
large urban areas where you have vast

143
00:06:29,350 --> 00:06:28,319
expanses of a city and it's primarily

144
00:06:31,350 --> 00:06:29,360
gray

145
00:06:34,870 --> 00:06:31,360
and then you can see where the where the

146
00:06:37,189 --> 00:06:34,880
plants are thriving

147
00:06:39,510 --> 00:06:37,199
and this is in the bahamas

148
00:06:41,670 --> 00:06:39,520
in the caribbean area

149
00:06:43,749 --> 00:06:41,680
very beautiful from orbit you see the

150
00:06:46,230 --> 00:06:43,759
turquoise water with a little island

151
00:06:48,150 --> 00:06:46,240
circling it there's no other place on

152
00:06:50,070 --> 00:06:48,160
the planet that looks quite like this

153
00:06:53,589 --> 00:06:50,080
but let's see what this looks like in

154
00:06:59,990 --> 00:06:56,950
almost looks like van gogh and matisse

155
00:07:01,990 --> 00:07:00,000
got together to make a painting and mix

156
00:07:04,550 --> 00:07:02,000
their palettes not only are they

157
00:07:07,189 --> 00:07:04,560
beautiful from an artistic point of view

158
00:07:08,150 --> 00:07:07,199
but i'm hoping the earth scientists will

159
00:07:11,110 --> 00:07:08,160
find

160
00:07:14,950 --> 00:07:11,120
information here that that they will

161
00:07:20,469 --> 00:07:17,589
and the camera we have has the

162
00:07:22,950 --> 00:07:20,479
capability of making high definition

163
00:07:25,350 --> 00:07:22,960
movies and so i took the liberty to make

164
00:07:27,830 --> 00:07:25,360
uh an infrared movie and this is a path

165
00:07:33,430 --> 00:07:27,840
going over the andes mountains into

166
00:07:39,189 --> 00:07:35,990
and that concludes this gun

167
00:07:41,430 --> 00:07:39,199
this one was about the color infrared a

168
00:07:44,230 --> 00:07:41,440
digital camera that we now have on space

169
00:07:46,629 --> 00:07:44,240
station that replaces our lost

170
00:07:48,950 --> 00:07:46,639
capability a color infrared film since

171
00:07:52,869 --> 00:07:48,960
we no longer fly from the space station

172
00:07:54,950 --> 00:07:52,879
and now we as crew can use this camera

173
00:07:59,189 --> 00:07:54,960
to make those still images

174
00:08:00,869 --> 00:07:59,199
and uh and movies of targets that will

175
00:08:03,350 --> 00:08:00,879
be of interest to not only earth

176
00:08:08,070 --> 00:08:03,360
scientists but also just
