I'm the project scientist on The Lucy Mission and 
we have benefited greatly from Hubble.

2
00:00:14.460 --> 00:00:23.040
Lucy launched on October 16 2021. "Liftoff Atlas 5 
takes flight sending Lucy to uncover the fossils  

3
00:00:23.040 --> 00:00:29.580
of our solar system." It's an 11 and a half year 
Mission because we are going relatively far from  

4
00:00:29.580 --> 00:00:34.200
the earth we're visiting both the leading and 
trailing group of the Trojan asteroids they've  

5
00:00:34.200 --> 00:00:39.000
never been explored before with a spacecraft 
they are in the same orbit around the Sun as  

6
00:00:39.000 --> 00:00:45.180
Jupiter but they're trailing Jupiter or leading 
it by about 60 degrees so they stay almost the  

7
00:00:45.180 --> 00:00:49.380
same distance from Jupiter as they are from 
the Sun and they're there because it's sort  

8
00:00:49.380 --> 00:00:58.140
of a gravitational fly trap. We began in this 
intensive surgery Hubble around the Lucy targets  

9
00:00:58.140 --> 00:01:03.900
once we knew the Lucy mission was going it's 
a difficult observation it requires going very  

10
00:01:03.900 --> 00:01:09.180
very deep with Hubble and even then it was right 
at the barely at the edge of what Hubble could do.  

11
00:01:09.900 --> 00:01:15.120
We did find the satellite of one of our 
targets as an asteroid named Euribides  

12
00:01:15.120 --> 00:01:19.200
and it has a tiny satellite that we named 
Queta that was found directly with Hubble.  

13
00:01:20.940 --> 00:01:27.420
We took our cue for that search from 
the New Horizons mission to Pluto.  

14
00:01:27.420 --> 00:01:35.700
Hubble did that by finding four satellites two 
Nix and Hydra were found in 2005 and then the  

15
00:01:35.700 --> 00:01:40.920
next couple were found years later when they 
realized the orbital configuration of Nix and

16
00:01:40.920 --> 00:01:46.380
Hydra looked like there might be more and that 
really enabled a lot of science because we were  

17
00:01:46.380 --> 00:01:52.080
able to plan ahead and make observations with 
the New Horizons spacecraft when it went by.

18
00:01:54.660 --> 00:01:59.940
Now that we know that there are these satellites 
around two of the Lucy targets we'll be able  

19
00:01:59.940 --> 00:02:05.400
to plan ahead and utilize that knowledge 
to get images and more information about  

20
00:02:05.400 --> 00:02:13.260
those targets when we fly by. What 
Hubble Is uniquely good at doing is  

21
00:02:13.260 --> 00:02:19.020
the kind of observation of these faint distant 
things that you really can't do any other way.
