and to take off
at about 8:00 AM.

12
00:00:27,200 --> 00:00:28,960
The forecasters will look
at the conditions,

13
00:00:28,960 --> 00:00:31,160
to verify that the
flight is ready to go

14
00:00:31,160 --> 00:00:33,760

There's a lot of talk
on the headsets

22
00:01:22,760 --> 00:01:26,160
about what we're seeing
and whether it makes sense

23
00:01:26,160 --> 00:01:27,960
in terms of what the
models had predicted.

24
00:01:27,960 --> 00:01:29,760
Don't forget that this aircraft

25
00:01:29,760 --> 00:01:31,000
is flying in the atmosphere

26
00:01:31,000 --> 00:01:32,520
to verify whether the models

can do a good job of
predicting air quality.

28
00:01:38,240 --> 00:01:42,120
Each flight begins with a pass
through the city of Seoul,

29
00:01:42,360 --> 00:01:44,320
for a chance to see
what that looks like,

30
00:01:44,640 --> 00:01:46,240
and then we go to high altitude

31
00:01:46,240 --> 00:01:50,160
to fly along the peninsula along
a route that we've chosen

32
00:01:50,160 --> 00:01:52,400
and looking down, with
what we call the “LIDAR”.

33
00:01:52,680 --> 00:01:54,880
The lasers that point
underneath the aircraft,

34
00:01:54,880 --> 00:01:57,040
provide information on
the pollution levels

35
00:01:57,040 --> 00:01:59,160
at different altitudes
down toward the ground.

36
00:01:59,320 --> 00:02:01,520
And we have to use that
information to decide

37
00:02:01,520 --> 00:02:04,160
where we will want
to sample in altitude

38
00:02:04,160 --> 00:02:07,560
along that same path
following the LIDAR pass.

39
00:02:11,880 --> 00:02:14,400
That 8 hour flight
does not stop us

40
00:02:14,400 --> 00:02:16,600
from continuing
forecasting on the ground

41
00:02:16,600 --> 00:02:20,040
and trying to give information
to the flight as it happens

42
00:02:20,040 --> 00:02:22,120
in case conditions change.

43
00:02:25,640 --> 00:02:27,560
And so those days
can be very busy

44
00:02:27,560 --> 00:02:29,400
between planning
tomorrow's flight

45
00:02:29,400 --> 00:02:31,920

today's flight happens well.

for the scientists
onboard the aircraft.

48
00:02:38,560 --> 00:02:40,280
However, there are other teams

49
00:02:40,280 --> 00:02:42,480
that also have to be working
around the clock

50
00:02:42,480 --> 00:02:45,080
in order to have these
airborne laboratories ready

51
00:02:45,080 --> 00:02:47,320
for investigating
the atmosphere.

52
00:02:50,040 --> 00:02:52,400
>>On this mission, the
maintenance crew is pretty busy.

53
00:02:52,400 --> 00:02:54,400
We've got so many
scientists on board...

54
00:02:54,400 --> 00:02:55,400
All the scientists have

55
00:02:55,400 --> 00:02:56,920
different needs and requirements

56
00:02:56,920 --> 00:02:58,360
such as changing out some of

57
00:02:58,360 --> 00:03:00,400
the gasses they
have on the airplane.

58
00:03:00,640 --> 00:03:04,480
They also make sure that the
airplane is pre-flight right

59
00:03:04,480 --> 00:03:06,200
so we're good to go.

60
00:03:06,200 --> 00:03:09,200
Check a lot of the systems...
refueling the airplane...

61
00:03:09,800 --> 00:03:13,480
Before the flight, they take off
those covers off all the probes

62
00:03:13,480 --> 00:03:15,800
which actually takes
quite a while.

63
00:03:15,800 --> 00:03:17,160
And then, after the flight,

64
00:03:17,160 --> 00:03:18,800
they need to put
those back in place.

65
00:03:19,000 --> 00:03:20,040
So, the maintenance crew...

66
00:03:20,040 --> 00:03:21,800
They are the first guys
to show up in the morning

67
00:03:21,800 --> 00:03:23,920
and the last guys to leave
at the end of the day.

68
00:03:24,400 --> 00:03:27,280
They make sure we have a good
jet for that day's mission

69
00:03:27,960 --> 00:03:30,160
and, if we break the jet
on that mission,

70
00:03:30,160 --> 00:03:32,000
they're the ones
who got to fix it

71
00:03:32,000 --> 00:03:33,920
and get it ready
for the next one.

72
00:03:37,880 --> 00:03:41,280
>>Teamwork is the key to
a successful campaign.

73
00:03:44,360 --> 00:03:46,480
The KORUS-AQ mission involves

74
00:03:46,480 --> 00:03:49,480
the coordinated effort
of over 500 people!

75
00:03:51,560 --> 00:03:54,480
>>We have 505 people registered
on the mission website

76
00:03:54,480 --> 00:03:56,400
and, of those, about 300

77
00:03:56,400 --> 00:03:58,120
have been active participants

78
00:03:58,120 --> 00:03:59,920
at some point
during the deployment.

79
00:03:59,920 --> 00:04:00,920
And we have to ensure that

80
00:04:00,920 --> 00:04:02,240
everybody had access

81
00:04:02,240 --> 00:04:03,560
when they needed it.

82
00:04:04,480 --> 00:04:07,440
>>Scientists, crew, technicians...

83
00:04:07,720 --> 00:04:11,520
but also equipment,
supplies, logistics...

84
00:04:12,560 --> 00:04:14,920
A massive scientific
research mission

85
00:04:14,920 --> 00:04:19,040
requires planning ahead
and effective management.

86
00:04:21,060 --> 00:04:22,860
>>Preparations for
something of this size

87
00:04:22,880 --> 00:04:24,400
begin years in advance.

88
00:04:24,560 --> 00:04:26,160
So having already visited here

89
00:04:26,160 --> 00:04:28,440
with the Earth Science Project
Office several times

90
00:04:28,440 --> 00:04:30,120
we were able to put together

91
00:04:30,120 --> 00:04:32,280
a situation that would enable

92
00:04:32,280 --> 00:04:33,480
this many scientists

93
00:04:33,480 --> 00:04:35,920
and these many resources
to be put into play.

94
00:04:38,800 --> 00:04:41,040
>>ESPO is involved in all
phases of the mission,

95
00:04:41,040 --> 00:04:42,640
from its conception,

96
00:04:42,640 --> 00:04:44,960
to its planning and
the implementation.

97
00:04:45,400 --> 00:04:48,120
We need to understand
what the researchers want,

98
00:04:48,120 --> 00:04:49,680
which become our requirements,

99
00:04:49,680 --> 00:04:51,240
and then we come here

100
00:04:51,240 --> 00:04:53,960
and see how we can best
meet those requirements,

101
00:04:53,960 --> 00:04:56,720
whether they are logistical
or operational.

102
00:04:57,440 --> 00:04:59,360
>>The Earth Science Project Office

103
00:04:59,360 --> 00:05:01,280
is in charge of
managing the mission.

104
00:05:01,640 --> 00:05:03,640
Anything you need to
accomplish your objectives

105
00:05:03,640 --> 00:05:04,640
during the mission...

106
00:05:04,880 --> 00:05:06,600
They are the people to go to!

107
00:05:07,800 --> 00:05:09,560
>>Entering a foreign country
is very difficult

108
00:05:09,560 --> 00:05:11,080
with all the things
that we bring...

109
00:05:11,280 --> 00:05:13,160
Operating in a foreign
country is difficult

110
00:05:13,160 --> 00:05:15,400
because their airspace
is very busy and maybe

111
00:05:15,400 --> 00:05:17,480
some of their procedures
are different than ours...

112
00:05:17,720 --> 00:05:19,840
and keeping the flow of people

113
00:05:20,080 --> 00:05:23,480
and information
and equipment smooth

114
00:05:24,200 --> 00:05:26,080
and, in a way that
does not interrupt

115
00:05:26,080 --> 00:05:28,120
or distract us from the science,

116
00:05:28,120 --> 00:05:29,360
is a great talent

117
00:05:29,360 --> 00:05:32,880
and we appreciate the Earth
Science Project Office support.

118
00:05:34,120 --> 00:05:36,320
>>They are the ones making
sure scientists have

119
00:05:36,320 --> 00:05:39,320
everything they need
to keep working every day.

120
00:05:41,320 --> 00:05:43,080
So if you want
to do a good job...

121
00:05:43,320 --> 00:05:45,080
you have to go
to the right place

122
00:05:45,280 --> 00:05:46,960
and measure at the right time

123
00:05:47,160 --> 00:05:48,560
with the right people.

124
00:05:49,040 --> 00:05:51,440
And for these people,
the right place...

125
00:05:51,640 --> 00:05:53,200
is in the air!

126
00:05:58,080 --> 00:06:00,240
Although in the end, for them,

127
00:06:00,240 --> 00:06:03,080
maybe it wasn't just like
another day at the office!

128
00:06:04,960 --> 00:06:07,040
>>Yeah! It's a totally
different experience.

129
00:06:07,240 --> 00:06:08,760
>>The work we do here day to day

130
00:06:08,760 --> 00:06:10,480
is much different than
what we do in the lab.

131
00:06:10,480 --> 00:06:13,880
>>I've been waking up pretty
early, at about 4 am...

132
00:06:14,120 --> 00:06:16,360
and then we get out
here at about five

133
00:06:16,360 --> 00:06:18,320
to warm up our instrument
because the laser

134
00:06:18,320 --> 00:06:20,800
takes a while to warm up
to peak power.

135
00:06:20,800 --> 00:06:22,560
>>We'll be taking out
gas cylinders...

136
00:06:22,560 --> 00:06:24,040
and putting in new ones...

137
00:06:24,040 --> 00:06:27,120
>>After every flight we
switch out the air canisters

138
00:06:27,120 --> 00:06:28,440
for the next day's flight...

139
00:06:28,440 --> 00:06:31,200
>>Filling water or
calibrating the instruments...

140
00:06:31,200 --> 00:06:33,160
making sure they're
running correctly...

141
00:06:33,160 --> 00:06:34,160
>>And then we come back out

142
00:06:34,160 --> 00:06:35,800
and mess with the
laser a little more...

143
00:06:35,800 --> 00:06:39,760
>>So I've definitely developed
my muscle mass here!

144
00:06:40,640 --> 00:06:42,760
>>It's a lot of work...
but it's also a lot of fun!

145
00:06:42,760 --> 00:06:44,120
And definitely different
