1
00:00:08,008 --> 00:00:10,844
these measurements
have never been made before.

2
00:00:10,844 --> 00:00:14,414
Similar measurements
have been made, but decades ago,

3
00:00:14,414 --> 00:00:17,417
not nearly as detailed
or as careful.

4
00:00:17,484 --> 00:00:22,422
And these are new measurements
that will be able to provide

5
00:00:22,422 --> 00:00:25,759
data that gets applied
to the climate

6
00:00:25,759 --> 00:00:29,763
models.

7
00:00:29,863 --> 00:00:33,366
I'm excited about this mission
because I know it'll have a long

8
00:00:33,366 --> 00:00:37,137
lasting impact on the science
and that that science

9
00:00:37,137 --> 00:00:40,407
is very much directed
at the humanity of this earth

10
00:00:40,473 --> 00:00:43,977
and that these measurements
will be around

11
00:00:43,977 --> 00:00:45,745
for a long, long time
and that the

12
00:00:45,745 --> 00:00:48,748
scientists of the world
will be using these

13
00:00:48,915 --> 00:00:52,252
to rely on heavily
for the next five years.

14
00:00:52,285 --> 00:00:56,856
There will be future missions
that bring even better data.

15
00:00:56,923 --> 00:01:00,093
But I think even for ten, 15,
20 years,

16
00:01:00,093 --> 00:01:01,027
these measurements

17
00:01:01,027 --> 00:01:04,998
will be used by scientists
to inform our understanding

18
00:01:04,998 --> 00:01:12,639
of the earth and the processes
of heat loss for the earth.

19
00:01:12,739 --> 00:01:16,142
So there was actually
a lot of engineering development

20
00:01:16,142 --> 00:01:19,112
that went into building
this instrument.

21
00:01:19,145 --> 00:01:21,581
the instruments
are designed at JPL,

22
00:01:21,581 --> 00:01:24,150
and they're brought together
from components.

23
00:01:24,150 --> 00:01:27,821
JPL is previously built before,
but they needed to be

24
00:01:27,821 --> 00:01:30,824
completely re-engineered
and scaled down

25
00:01:30,824 --> 00:01:35,228
in most cases.

26
00:01:35,328 --> 00:01:38,798
So there have been measurements
made of the heat

27
00:01:38,798 --> 00:01:43,369
loss from Earth,
but only heat in certain ranges

28
00:01:43,470 --> 00:01:47,107
from the really hotter,
warmer temperatures.

29
00:01:47,173 --> 00:01:47,674
And yeah,

30
00:01:47,674 --> 00:01:49,909
there's still a lot of heat
that's lost

31
00:01:49,909 --> 00:01:53,413
from the cooler temperatures,
which is what we're really going

32
00:01:53,413 --> 00:01:56,382
to be able to measure
by going over the poles.

33
00:01:56,382 --> 00:02:00,687
And that's such an unknown
area of science

34
00:02:00,687 --> 00:02:03,857
that the scientists
are now building in a

35
00:02:03,857 --> 00:02:08,728
theoretical assumption for what
is being lost from the earth.

36
00:02:08,795 --> 00:02:10,797
But by making
these measurements,

37
00:02:10,797 --> 00:02:14,501
we can give them actual data
so they're no longer reliant

38
00:02:14,501 --> 00:02:19,339
on their various various
assumptions about what it is.
