00:00:00.967 --> 00:00:04.571
NASA’s Lucy mission is heading
to the Jupiter Trojans

3
00:00:04.571 --> 00:00:07.007
two swarms of unexplored
asteroids

4
00:00:07.007 --> 00:00:09.342
trapped in Jupiter’s orbit.

00:00:09.342 --> 00:00:11.845
Because Lucy will venture
further from the Sun

6
00:00:11.845 --> 00:00:14.114
than any previous solar-powered
spacecraft

7
00:00:14.114 --> 00:00:16.716
it is equipped with two
expansive solar arrays

8
00:00:16.716 --> 00:00:19.019
to carry out its deep
space journey.

LAUNCH COMMENTATOR
Liftoff! Atlas V takes flight,

10
00:00:21.955 --> 00:00:25.458
sending Lucy to uncover the
fossils of our solar system.

11
00:00:25.925 --> 00:00:29.496
In the early morning hours of
October 16, 2021,

12
00:00:29.496 --> 00:00:33.199
Lucy rose above Cape Canaveral
in a picture-perfect launch.

13
00:00:33.199 --> 00:00:36.503
But when the spacecraft
began to unfurl its solar arrays

14
00:00:36.503 --> 00:00:38.605
it encountered an anomaly.

15
00:00:38.605 --> 00:00:41.908
One of the arrays failed to
fully deploy and latch shut,

16
00:00:41.908 --> 00:00:44.344
putting the mission at risk.

17
00:00:44.344 --> 00:00:47.013
Lucy’s cameras are not pointed
at the spacecraft,

18
00:00:47.013 --> 00:00:50.617
so the flight operations team
could not see what had happened.

19
00:00:50.617 --> 00:00:53.787
Instead, they had to work with
spare equipment on the ground,

20
00:00:53.787 --> 00:00:56.790
computer models, and data from
Lucy to piece together

21
00:00:56.790 --> 00:01:00.126
the puzzle and determine the
best path forward.

22
00:01:00.126 --> 00:01:02.495
After months of analysis and
testing, the team

23
00:01:02.495 --> 00:01:05.698
sent the spacecraft a series of
carefully developed commands

24
00:01:05.698 --> 00:01:07.901
to further deploy the array,
stabilizing it

25
00:01:07.901 --> 00:01:10.070
sufficiently for the mission
to proceed.

27
00:01:12.405 --> 00:01:14.474
Now Lucy can continue
its journey

28
00:01:14.474 --> 00:01:17.377
setting course for a darker
region of space,

29
00:01:17.377 --> 00:01:19.512
powered by the distant Sun.
