1
00:00:05,690 --> 00:00:02,869
hey everyone I'm Marina jurika with

2
00:00:07,430 --> 00:00:05,700
NASA's jet propulsion laboratory and

3
00:00:09,770 --> 00:00:07,440
we're live here on lab in Southern

4
00:00:12,950 --> 00:00:09,780
California to tell you a little bit more

5
00:00:16,670 --> 00:00:12,960
about the SWAT Mission now the Swatch

6
00:00:18,769 --> 00:00:16,680
satellite will be observing almost 90

7
00:00:21,290 --> 00:00:18,779
percent of the water on the Earth's

8
00:00:23,630 --> 00:00:21,300
surface for the first time and the swap

9
00:00:27,290 --> 00:00:23,640
mission is led by NASA and the French

10
00:00:30,050 --> 00:00:27,300
space agency canes and here to tell me a

11
00:00:32,210 --> 00:00:30,060
little bit more about what SWAT will do

12
00:00:35,750 --> 00:00:32,220
and how it will benefit each and every

13
00:00:38,270 --> 00:00:35,760
one of us is JPL hydrologist Cedric

14
00:00:40,490 --> 00:00:38,280
David and I'm going to be calling him

15
00:00:51,410 --> 00:00:40,500
into this Instagram live right now so

16
00:00:51,420 --> 00:01:02,029
all right just sent him the invitation

17
00:01:07,609 --> 00:01:04,609
and they're used hello Cedric can you

18
00:01:08,170 --> 00:01:07,619
hear me yes hi are we live this is it we

19
00:01:10,030 --> 00:01:08,180
are Live

20
00:01:12,230 --> 00:01:10,040
[Laughter]

21
00:01:14,510 --> 00:01:12,240
Well Cedric thank you so much for

22
00:01:16,190 --> 00:01:14,520
joining us today well thanks for having

23
00:01:17,690 --> 00:01:16,200
me and hello everyone out there on the

24
00:01:19,850 --> 00:01:17,700
internet thank you for joining us for

25
00:01:21,350 --> 00:01:19,860
the SWAT Revolution

26
00:01:23,929 --> 00:01:21,360
all right so tell me a little bit about

27
00:01:26,270 --> 00:01:23,939
where you're joining us from today so

28
00:01:28,310 --> 00:01:26,280
I'm currently standing in the Von Carmen

29
00:01:30,649 --> 00:01:28,320
auditorium at Nasa Street propulsion

30
00:01:32,690 --> 00:01:30,659
laboratory in Pasadena California and

31
00:01:35,090 --> 00:01:32,700
I'm standing right in front of a

32
00:01:37,249 --> 00:01:35,100
miniaturized model right here of the

33
00:01:39,710 --> 00:01:37,259
SWAT spacecraft that is three times

34
00:01:41,510 --> 00:01:39,720
smarter than the real Dion that has none

35
00:01:44,330 --> 00:01:41,520
of the bells and whistles of what we'll

36
00:01:46,370 --> 00:01:44,340
be launching into space next week

37
00:01:48,109 --> 00:01:46,380
and I wanted to thank so many people who

38
00:01:50,929 --> 00:01:48,119
are joining us I can see a lot of people

39
00:01:52,969 --> 00:01:50,939
are starting to sign in and I'm very

40
00:01:55,609 --> 00:01:52,979
happy to see everybody getting excited

41
00:01:58,969 --> 00:01:55,619
about this very unique Mission so tell

42
00:02:01,429 --> 00:01:58,979
us Cedric what SWAT stands for and also

43
00:02:03,410 --> 00:02:01,439
what it's going to do to benefit the

44
00:02:08,150 --> 00:02:03,420
work that you do as a hydrologist

45
00:02:10,969 --> 00:02:08,160
so SWAT is s-w-o-t it stands for surface

46
00:02:13,190 --> 00:02:10,979
water and ocean topography it's a new

47
00:02:15,949 --> 00:02:13,200
space mission will be launching next

48
00:02:18,650 --> 00:02:15,959
week and it will be observing all the

49
00:02:21,410 --> 00:02:18,660
waters on Earth 90 of the waters on

50
00:02:23,630 --> 00:02:21,420
Earth on two sides in the ocean and on

51
00:02:26,089 --> 00:02:23,640
the land and what we'll do is we'll be

52
00:02:27,410 --> 00:02:26,099
seeing where water is and how high it is

53
00:02:30,170 --> 00:02:27,420
and from that we can know where it's

54
00:02:32,390 --> 00:02:30,180
going it's really incredible and the

55
00:02:34,369 --> 00:02:32,400
ocean we'll be continuing 30 years of

56
00:02:36,830 --> 00:02:34,379
observations of sea levels but doing

57
00:02:38,630 --> 00:02:36,840
that in such a much finer way that we'll

58
00:02:40,430 --> 00:02:38,640
be able to better understand ocean

59
00:02:42,650 --> 00:02:40,440
currents and that's really important for

60
00:02:44,690 --> 00:02:42,660
things like navigation for example

61
00:02:46,309 --> 00:02:44,700
now on land on the continents and that's

62
00:02:48,229 --> 00:02:46,319
really what I do on an everyday basis

63
00:02:51,050 --> 00:02:48,239
that I'm really excited about we'll be

64
00:02:53,210 --> 00:02:51,060
looking at rivers lakes reservoirs so

65
00:02:55,670 --> 00:02:53,220
we'll know where they are how high they

66
00:02:58,009 --> 00:02:55,680
are and how much water is Flowing which

67
00:02:59,869 --> 00:02:58,019
means that we will know the changes in

68
00:03:02,210 --> 00:02:59,879
the volume of water the storage how much

69
00:03:04,190 --> 00:03:02,220
water we have on on continents in those

70
00:03:06,229 --> 00:03:04,200
water bodies but we also know how much

71
00:03:09,470 --> 00:03:06,239
water is flowing through them and that's

72
00:03:10,970 --> 00:03:09,480
kind of like taking the pulse on Earth's

73
00:03:12,830 --> 00:03:10,980
arteries because Earth is a living

74
00:03:14,570 --> 00:03:12,840
planet and it's the same thing that when

75
00:03:16,790 --> 00:03:14,580
we go to the doctor to take our pulse

76
00:03:19,369 --> 00:03:16,800
we'll be doing that from space for the

77
00:03:21,410 --> 00:03:19,379
Earth's rivers with satellites

78
00:03:22,910 --> 00:03:21,420
and for the first time Cedric which is

79
00:03:25,490 --> 00:03:22,920
great and we really need to know about

80
00:03:28,850 --> 00:03:25,500
that pulse because we need to know about

81
00:03:30,649 --> 00:03:28,860
fresh water to be able to survive so I'm

82
00:03:32,089 --> 00:03:30,659
very excited about this as well too now

83
00:03:34,130 --> 00:03:32,099
what made you want to become a

84
00:03:35,930 --> 00:03:34,140
hydrologist and for folks out there who

85
00:03:38,089 --> 00:03:35,940
might be interested in this field what

86
00:03:41,210 --> 00:03:38,099
advice do you have for them well so I

87
00:03:42,949 --> 00:03:41,220
have a thankful for water uh Marina but

88
00:03:44,449 --> 00:03:42,959
I've always been curious about the

89
00:03:47,089 --> 00:03:44,459
environment just understanding what's

90
00:03:50,270 --> 00:03:47,099
happening around us and what's so great

91
00:03:52,610 --> 00:03:50,280
with NASA is that of course we go into

92
00:03:54,949 --> 00:03:52,620
space we look in the solar system and

93
00:03:57,350 --> 00:03:54,959
beyond and all that is incredibly

94
00:03:58,729 --> 00:03:57,360
exciting and important but as long as

95
00:04:01,789 --> 00:03:58,739
we've been looking we haven't really

96
00:04:04,430 --> 00:04:01,799
found another planet for us to live on

97
00:04:07,250 --> 00:04:04,440
right so planet Earth remains Planet a

98
00:04:08,509 --> 00:04:07,260
and there is no Planet B what this means

99
00:04:10,729 --> 00:04:08,519
is that it's very important for us to

100
00:04:12,530 --> 00:04:10,739
understand how our planet works and the

101
00:04:14,809 --> 00:04:12,540
way we do that is we ship satellites up

102
00:04:17,030 --> 00:04:14,819
in in space and they rotate around the

103
00:04:19,670 --> 00:04:17,040
earth and they take Earth selfies to

104
00:04:22,250 --> 00:04:19,680
help us observe many

105
00:04:23,870 --> 00:04:22,260
of the of many characteristics of the

106
00:04:25,610 --> 00:04:23,880
natural environment that allow us to

107
00:04:27,530 --> 00:04:25,620
plan for future Generations is really

108
00:04:30,590 --> 00:04:27,540
really important

109
00:04:32,409 --> 00:04:30,600
and also on that same vein it is an

110
00:04:34,610 --> 00:04:32,419
international truly an international

111
00:04:37,129 --> 00:04:34,620
collaboration so tell us a little bit

112
00:04:39,050 --> 00:04:37,139
about everyone who is involved with this

113
00:04:41,990 --> 00:04:39,060
swap Mission why it plays a little

114
00:04:44,170 --> 00:04:42,000
special place in your heart as well yeah

115
00:04:46,490 --> 00:04:44,180
so you're right this is an international

116
00:04:48,050 --> 00:04:46,500
collaboration with hundreds if not

117
00:04:49,670 --> 00:04:48,060
thousands of people right and it's just

118
00:04:51,409 --> 00:04:49,680
two of us talking about it but so many

119
00:04:54,110 --> 00:04:51,419
people have been involved in the mission

120
00:04:56,689 --> 00:04:54,120
for many years and so it's currently an

121
00:04:59,629 --> 00:04:56,699
international collaboration between NASA

122
00:05:01,790 --> 00:04:59,639
the French space agency kness but also

123
00:05:03,409 --> 00:05:01,800
the UK space agency and the Canadian

124
00:05:06,110 --> 00:05:03,419
space agency so an international

125
00:05:08,270 --> 00:05:06,120
collaboration International effort kind

126
00:05:10,070 --> 00:05:08,280
of like the World Cup except that at the

127
00:05:12,050 --> 00:05:10,080
end everybody wins because we all

128
00:05:14,990 --> 00:05:12,060
understand better about the Earth's uh

129
00:05:17,450 --> 00:05:15,000
water cycle now just so happens that I

130
00:05:20,090 --> 00:05:17,460
was born in France and I've lived in the

131
00:05:22,310 --> 00:05:20,100
US for nearly 20 years and I study the

132
00:05:24,710 --> 00:05:22,320
world's Rivers so there are three things

133
00:05:26,990 --> 00:05:24,720
about this that that connect me to the

134
00:05:29,270 --> 00:05:27,000
swap mission that makes it kind of a

135
00:05:31,249 --> 00:05:29,280
little bit of a match made in heaven for

136
00:05:33,050 --> 00:05:31,259
me to play a very small part in a huge

137
00:05:35,689 --> 00:05:33,060
mission

138
00:05:38,450 --> 00:05:35,699
and at International collaboration truly

139
00:05:41,029 --> 00:05:38,460
shows that water unites us all which is

140
00:05:42,710 --> 00:05:41,039
a really really amazing so we've talked

141
00:05:45,170 --> 00:05:42,720
a little bit about how SWAT is going to

142
00:05:47,629 --> 00:05:45,180
track almost 90 percent of the water on

143
00:05:49,969 --> 00:05:47,639
the Earth's surface why is that so

144
00:05:52,430 --> 00:05:49,979
critical not only to us understanding

145
00:05:55,610 --> 00:05:52,440
the water on Earth but for your work as

146
00:05:57,830 --> 00:05:55,620
well yeah so water is is very important

147
00:05:59,749 --> 00:05:57,840
for me I have a special connection with

148
00:06:01,490 --> 00:05:59,759
water it's my lifelong friend and my

149
00:06:03,409 --> 00:06:01,500
happy place and I encourage our audience

150
00:06:05,270 --> 00:06:03,419
to go look at the at the video that we

151
00:06:07,370 --> 00:06:05,280
recently released on my adventure with

152
00:06:09,110 --> 00:06:07,380
water but now for us all

153
00:06:10,850 --> 00:06:09,120
and I'll focus on the continents because

154
00:06:14,570 --> 00:06:10,860
that's my thing

155
00:06:16,550 --> 00:06:14,580
um the United Nation tells us that safe

156
00:06:19,310 --> 00:06:16,560
access to fresh water for drinking and

157
00:06:20,689 --> 00:06:19,320
for sanitation is a human right now if

158
00:06:23,270 --> 00:06:20,699
you think about it

159
00:06:25,850 --> 00:06:23,280
on Earth 200 years ago was one billion

160
00:06:28,370 --> 00:06:25,860
people with a B right and now it's more

161
00:06:29,990 --> 00:06:28,380
than 8 billion people the amount of

162
00:06:32,150 --> 00:06:30,000
water that we've had on Earth has been

163
00:06:34,430 --> 00:06:32,160
the same since the beginning of times

164
00:06:37,129 --> 00:06:34,440
but with more and more people it's very

165
00:06:38,930 --> 00:06:37,139
important to make sure we we understand

166
00:06:40,969 --> 00:06:38,940
how the water is moving around the earth

167
00:06:43,550 --> 00:06:40,979
as best as possible so that we can

168
00:06:45,830 --> 00:06:43,560
ensure safe access to fresh water for

169
00:06:48,590 --> 00:06:45,840
everyone on this planet

170
00:06:50,809 --> 00:06:48,600
that's so important and earlier you were

171
00:06:54,230 --> 00:06:50,819
talking about how there's the spacecraft

172
00:06:56,570 --> 00:06:54,240
model right behind you so tell us a

173
00:06:58,670 --> 00:06:56,580
little bit about what you think is the

174
00:07:02,390 --> 00:06:58,680
coolest part of this satellite yeah

175
00:07:04,909 --> 00:07:02,400
Marina do you like fireworks I do okay I

176
00:07:07,610 --> 00:07:04,919
love Fireworks right it's it's so

177
00:07:10,670 --> 00:07:07,620
exciting so this spacecraft in real life

178
00:07:12,710 --> 00:07:10,680
it's 30 feet in width that's about 10

179
00:07:14,629 --> 00:07:12,720
meters right it's so big that it doesn't

180
00:07:16,610 --> 00:07:14,639
fit in the spacecraft it doesn't fit in

181
00:07:18,350 --> 00:07:16,620
the rocket and the rocket that will be

182
00:07:20,809 --> 00:07:18,360
shipping next week so that means we have

183
00:07:23,270 --> 00:07:20,819
to fold it we have incredible Engineers

184
00:07:25,189 --> 00:07:23,280
that figured out a way to fold the arms

185
00:07:28,249 --> 00:07:25,199
and then attach them with little

186
00:07:30,529 --> 00:07:28,259
pyrotechnic devices that are attached to

187
00:07:32,689 --> 00:07:30,539
Springs and what we'll do is once we've

188
00:07:36,230 --> 00:07:32,699
packed it put in the rocket launched it

189
00:07:37,909 --> 00:07:36,240
up in space will uh be doing the

190
00:07:39,890 --> 00:07:37,919
unfolding and that involves little

191
00:07:41,629 --> 00:07:39,900
explosions to release the Springs so

192
00:07:44,150 --> 00:07:41,639
that the arms can open up and be as big

193
00:07:46,550 --> 00:07:44,160
as they need to be so space pyrotechnics

194
00:07:47,770 --> 00:07:46,560
space fireworks I think it's just so

195
00:07:51,409 --> 00:07:47,780
cool

196
00:07:54,650 --> 00:07:51,419
it is and before we get to do all of

197
00:07:56,990 --> 00:07:54,660
that unfolding we've actually got to

198
00:07:59,029 --> 00:07:57,000
launch the spacecraft next week actually

199
00:08:01,430 --> 00:07:59,039
really close to where we are right now

200
00:08:03,650 --> 00:08:01,440
Cedric so where are you going to be for

201
00:08:06,290 --> 00:08:03,660
that big launch day next week well if

202
00:08:09,770 --> 00:08:06,300
all goes well I will be uh at the base

203
00:08:12,950 --> 00:08:09,780
in Vandenberg uh next week to uh be able

204
00:08:15,589 --> 00:08:12,960
to say Bon Voyage to the spacecraft the

205
00:08:19,309 --> 00:08:15,599
spacecraft and wish it uh save Journey

206
00:08:22,670 --> 00:08:19,319
Up Up and Away to space say go swap

207
00:08:25,730 --> 00:08:22,680
and so I know that a lot of your science

208
00:08:27,589 --> 00:08:25,740
will be of course after it launches but

209
00:08:29,629 --> 00:08:27,599
is there anything you know butterflies

210
00:08:31,309 --> 00:08:29,639
in your stomach is there anything that

211
00:08:33,829 --> 00:08:31,319
you are thinking of now as we're just

212
00:08:36,769 --> 00:08:33,839
one week away from launch I think it's

213
00:08:39,050 --> 00:08:36,779
butterflies and everybody's stomachs uh

214
00:08:40,610 --> 00:08:39,060
Marina you know it's as I was as I

215
00:08:41,810 --> 00:08:40,620
mentioned earlier is hundreds if not

216
00:08:43,430 --> 00:08:41,820
thousands of people who have been

217
00:08:45,230 --> 00:08:43,440
working on this mission for you know

218
00:08:47,630 --> 00:08:45,240
many of them much longer than I have

219
00:08:49,550 --> 00:08:47,640
it's been 20 years in the making and so

220
00:08:51,110 --> 00:08:49,560
you know every one of us has been

221
00:08:53,090 --> 00:08:51,120
working very hard to make sure that

222
00:08:55,550 --> 00:08:53,100
everything goes as planned and when

223
00:08:57,889 --> 00:08:55,560
finally we'll get the observations the

224
00:08:59,509 --> 00:08:57,899
data that we've been looking for that'll

225
00:09:01,190 --> 00:08:59,519
be something special but first things

226
00:09:03,230 --> 00:09:01,200
first let's make sure that it goes there

227
00:09:05,930 --> 00:09:03,240
and that everything goes well next week

228
00:09:08,030 --> 00:09:05,940
yes we have definitely all got our

229
00:09:10,310 --> 00:09:08,040
fingers crossed to make sure that it

230
00:09:12,769 --> 00:09:10,320
goes off without a hitch next week well

231
00:09:15,410 --> 00:09:12,779
thank you so much Cedric for joining us

232
00:09:17,630 --> 00:09:15,420
today we appreciate it so much good luck

233
00:09:19,009 --> 00:09:17,640
with the launch next week at Vandenberg

234
00:09:24,230 --> 00:09:19,019
and thank you so much for everything

235
00:09:28,310 --> 00:09:25,910
