1
00:00:00.666 --> 00:00:04.833
(music throughout) There are still five more Trojan asteroids
to explore on your 12 year journey,

2
00:00:05.250 --> 00:00:09.500
each one has a different story to tell
about the history of our Solar System.

3
00:00:10.166 --> 00:00:15.416
Next up is Polymele a mere twenty-one
kilometers or 13 miles in diameter.

4
00:00:16.083 --> 00:00:20.916
Afterwards, you'll be zooming by Leucas,
which rotates at an extremely slow rate

5
00:00:21.083 --> 00:00:25.083
with each day being about 18.5
Earth days long.

6
00:00:25.666 --> 00:00:30.416
Afterwards, you'll be on to Orus, which
might be rich in organics and carbon.

7
00:00:32.666 --> 00:00:36.500
Lastly, you'll be on your way to a twin
pair of asteroids, Patroclus

8
00:00:36.500 --> 00:00:40.666
and Menoetius. These asteroids,
relatively unchanged over

9
00:00:40.666 --> 00:00:45.750
four billion years, will give us a glimpse
of our Solar System's distant past.

10
00:00:46.500 --> 00:00:48.833
With each flyby of a Trojan asteroid.

11
00:00:49.000 --> 00:00:50.833
You'll be looking at time capsules

12
00:00:50.833 --> 00:00:54.833
from the birth of our Solar System
over four billion years ago.

13
00:00:55.416 --> 00:00:58.916
Lucy, what your observations
tell us about the composition

14
00:00:58.916 --> 00:01:02.666
and properties of the Trojan asteroids
could give us clues about how

15
00:01:02.666 --> 00:01:04.000
Earth came to be.

16
00:01:06.750 --> 00:01:10.083
Absolutely. Carry on your journey, Lucy.

17
00:01:10.416 --> 00:01:13.416
And don't forget to call
and show us what you find out there.

18
00:01:13.750 --> 00:01:15.500
We'll be waiting. Good luck.
