00:00:00.000 --> 00:00:04.129
(music throughout)

2
00:00:04.166 --> 00:00:07.750
Nope, Lucy, still
a little way to go before

3
00:00:07.750 --> 00:00:10.166
you get to your first Trojan asteroid.

4
00:00:10.583 --> 00:00:14.833
But it looks like you're coming up to
the main belt asteroid, Donald Johanson.

5
00:00:16.000 --> 00:00:19.333
Right. This will give you a chance
to check in on your instrumentation

6
00:00:19.583 --> 00:00:21.666
before you get out to the Trojans.

7
00:00:21.666 --> 00:00:23.750
This first instrument is called L'Ralph.

8
00:00:24.083 --> 00:00:26.666
It will take color
images of the Trojan asteroids

9
00:00:26.833 --> 00:00:30.083
using visible and infrared light,
helping scientists

10
00:00:30.083 --> 00:00:34.333
map craters and mountains and figure out
what the asteroids are made out of.

11
00:00:34.750 --> 00:00:36.750
Next, this is L'LORRI.

12
00:00:36.750 --> 00:00:38.916
The long range reconnaissance imager.

13
00:00:39.500 --> 00:00:40.833
This camera will provide

14
00:00:40.833 --> 00:00:44.833
the most detailed images
of the surfaces of the Trojan asteroids.

15
00:00:44.833 --> 00:00:49.250
To help scientists figure out what's been
happening since our Solar System formed.

16
00:00:49.416 --> 00:00:52.750
This is L'TES, the thermal
emission spectrometer,

17
00:00:53.166 --> 00:00:55.166
basically a touchless thermometer.

18
00:00:55.166 --> 00:00:58.500
It will measure the temperatures
on the Trojan asteroids' surfaces

19
00:00:58.500 --> 00:01:01.916
to tell scientists
whether the surfaces are rocky or dusty.

20
00:01:02.500 --> 00:01:05.916
Lastly, you couldn't get the job done
without your tracking cameras

21
00:01:05.916 --> 00:01:10.333
or the T2CAMS to make sure
the asteroids are always in view

22
00:01:10.916 --> 00:01:14.083
and the high gain antenna
that lets you communicate with Earth.

23
00:01:14.250 --> 00:01:17.416
The scientists back at home
will use your radio signals

24
00:01:17.583 --> 00:01:20.750
to measure the mass of each
asteroid as you fly past it.

25
00:01:22.083 --> 00:01:24.416
That's right, Lucy.

26
00:01:24.500 --> 00:01:25.666
How could I forget?

27
00:01:25.666 --> 00:01:28.416
You also have two huge solar panels

28
00:01:28.666 --> 00:01:32.250
to give you electrical power
as you fly out to the Trojan asteroids.

29
00:01:32.750 --> 00:01:36.166
Farther from the Sun
than any previous solar powered mission.

30
00:01:36.750 --> 00:01:39.916
Just a bit longer
now before you get to your first target.

31
00:01:40.666 --> 00:01:44.333
Rest up and get ready to put
all of those instruments to good use.

32
00:01:45.083 --> 00:01:48.750
I'll check back in with you once you
make it out to your first Trojan asteroid.
