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.

Because Lucy will venture
further from the Sun

00:00:11,845 --> 00:00:14,114
than any previous solar-powered
spacecraft

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.

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.

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.
