1
00:00:14,990 --> 00:00:12,980
spirit was never designed to last this

2
00:00:16,460 --> 00:00:15,000
long but you know it was Rover was never

3
00:00:18,499 --> 00:00:16,470
designed to go through Martian winter

4
00:00:21,260 --> 00:00:18,509
and she went through three winters

5
00:00:23,660 --> 00:00:21,270
successfully they were never designed to

6
00:00:26,750 --> 00:00:23,670
survive Rover killing dust storms and

7
00:00:28,910 --> 00:00:26,760
yet spirit survived several significant

8
00:00:30,800 --> 00:00:28,920
dust storms spear climbed the husband

9
00:00:32,570 --> 00:00:30,810
Hills it did Martian mountaineering yet

10
00:00:35,180 --> 00:00:32,580
another thing it was never designed to

11
00:00:38,479 --> 00:00:35,190
do so out of this Rover that had a very

12
00:00:41,119 --> 00:00:38,489
limited scope of mission to begin with

13
00:00:43,939 --> 00:00:41,129
we were able to do these magnificent

14
00:00:45,350 --> 00:00:43,949
adventures and the program was very

15
00:00:46,729 --> 00:00:45,360
successful in all that and it's a

16
00:00:48,560 --> 00:00:46,739
testament to the people that designed

17
00:00:50,360 --> 00:00:48,570
and built the rover and a testament to

18
00:00:52,670 --> 00:00:50,370
the people that operated the rover on

19
00:00:57,020 --> 00:00:52,680
the surface the whole mission has had a

20
00:00:59,000 --> 00:00:57,030
really amazing ability to turn what

21
00:01:01,640 --> 00:00:59,010
looks initially like it's going to be

22
00:01:05,810 --> 00:01:01,650
adversity into a great triumph and

23
00:01:08,090 --> 00:01:05,820
spirit in particular has really been

24
00:01:11,270 --> 00:01:08,100
known for this quality one of the things

25
00:01:14,570 --> 00:01:11,280
that characterize spirit on the surface

26
00:01:17,930 --> 00:01:14,580
of Mars was the ability of that Rover to

27
00:01:19,640 --> 00:01:17,940
turn lemons into lemonade a couple of

28
00:01:22,760 --> 00:01:19,650
years into the mission spirits right

29
00:01:24,590 --> 00:01:22,770
front wheel broke and we had to learn to

30
00:01:26,540 --> 00:01:24,600
drive the rover backwards in fact

31
00:01:29,180 --> 00:01:26,550
relearn how to drive the rover and we

32
00:01:31,040 --> 00:01:29,190
would drag that wheel but out of that

33
00:01:32,960 --> 00:01:31,050
adversity came perhaps the most

34
00:01:34,940 --> 00:01:32,970
significant scientific discovery on the

35
00:01:36,680 --> 00:01:34,950
surface of Mars we were hoping that

36
00:01:38,570 --> 00:01:36,690
spirit would find evidence of past water

37
00:01:40,190 --> 00:01:38,580
history at Mars and not only did Spirit

38
00:01:42,290 --> 00:01:40,200
find evidence of a past water history at

39
00:01:45,200 --> 00:01:42,300
Mars she found evidence of pH neutral

40
00:01:47,240 --> 00:01:45,210
water at comanche spur and she found

41
00:01:49,550 --> 00:01:47,250
evidence of hot water existing and kind

42
00:01:51,050 --> 00:01:49,560
of acting for long periods of time in

43
00:01:54,020 --> 00:01:51,060
the inner region near home plate that we

44
00:01:56,300 --> 00:01:54,030
call silica Valley so from a science

45
00:01:58,310 --> 00:01:56,310
perspective spirit smashed expectations

46
00:02:00,380 --> 00:01:58,320
right she did way better than we would

47
00:02:03,020 --> 00:02:00,390
ever possibly have hoped for what Spirit

48
00:02:05,330 --> 00:02:03,030
has told us is that Mars was one time

49
00:02:07,250 --> 00:02:05,340
like the earth some three-and-a-half to

50
00:02:08,749 --> 00:02:07,260
four billion years ago there was liquid

51
00:02:09,770 --> 00:02:08,759
water on the surface it was a thicker

52
00:02:11,539 --> 00:02:09,780
atmosphere there were warmer

53
00:02:13,670 --> 00:02:11,549
temperatures there were even sources of

54
00:02:15,680 --> 00:02:13,680
energy things like Hot Springs these are

55
00:02:17,930 --> 00:02:15,690
all discoveries that spirit has made and

56
00:02:20,540 --> 00:02:17,940
this completely changes are thinking

57
00:02:23,480 --> 00:02:20,550
about Mars that Mars was in fact

58
00:02:26,090 --> 00:02:23,490
time a place that could have supported

59
00:02:27,830 --> 00:02:26,100
life spirits legacy in terms of Mars

60
00:02:30,890 --> 00:02:27,840
exploration might be that she's making

61
00:02:32,600 --> 00:02:30,900
Mars a real place for us she has helped

62
00:02:35,600 --> 00:02:32,610
us to see what we would see if we were

63
00:02:39,290 --> 00:02:35,610
there I also hope that she again has a

64
00:02:42,080 --> 00:02:39,300
broader legacy and towards of continuing

65
00:02:44,330 --> 00:02:42,090
to inspire people to explore to reach

66
00:02:47,210 --> 00:02:44,340
out beyond what they think they can

67
00:02:49,850 --> 00:02:47,220
accomplish we always do there will come

68
00:02:51,770 --> 00:02:49,860
a time when one or the rover's wouldn't

69
00:02:54,710 --> 00:02:51,780
be there that's the interesting thing is

70
00:02:57,440 --> 00:02:54,720
that you do become very attached and you

71
00:02:59,780 --> 00:02:57,450
think of these Rovers really as part of

72
00:03:01,700 --> 00:02:59,790
your team and part of your family for

73
00:03:03,170 --> 00:03:01,710
years now then getting the question well

74
00:03:06,710 --> 00:03:03,180
how are you going to feel when she's

75
00:03:09,590 --> 00:03:06,720
gone and I've always had this image of

76
00:03:12,710 --> 00:03:09,600
sort of the New Orleans Jazz funeral

77
00:03:15,410 --> 00:03:12,720
procession where there's some sadness of

78
00:03:17,870 --> 00:03:15,420
course because spirit has been

79
00:03:20,120 --> 00:03:17,880
essentially my entire career at JPL

80
00:03:23,810 --> 00:03:20,130
working with these two Rovers there is

81
00:03:26,570 --> 00:03:23,820
just so much to celebrate a life if you

82
00:03:29,060 --> 00:03:26,580
will that lasted beyond any expectation

83
00:03:30,890 --> 00:03:29,070
discovered wonderful things so it's very

84
00:03:35,120 --> 00:03:30,900
bittersweet I'm always going to be

85
00:03:36,650 --> 00:03:35,130
really proud of spirit you know spirit

86
00:03:38,810 --> 00:03:36,660
was my first Mars rover and if you've

87
00:03:41,420 --> 00:03:38,820
ever had a first car you know a little

88
00:03:43,729 --> 00:03:41,430
bit about what that's like I have loved

89
00:03:45,530 --> 00:03:43,739
spirit from the early days when it

90
00:03:47,120 --> 00:03:45,540
seemed like nobody else did and I still

91
00:03:49,820 --> 00:03:47,130
do and she's always going to have a

92
00:03:51,440 --> 00:03:49,830
special place to me in my heart you know

93
00:03:55,460 --> 00:03:51,450
is there with her at the very beginning

94
00:03:58,490 --> 00:03:55,470
and she just took me and everybody on a

95
00:04:00,380 --> 00:03:58,500
terrific ride across the surface of Mars

96
00:04:02,360 --> 00:04:00,390
showed us things that nobody has ever

97
00:04:05,210 --> 00:04:02,370
seen before in the history of humanity

98
00:04:06,830 --> 00:04:05,220
opened up that other world for us and

99
00:04:08,690 --> 00:04:06,840
made it possible for us to see it from

100
00:04:11,240 --> 00:04:08,700
the first time as if we were there and

101
00:04:12,320 --> 00:04:11,250
I'm always going to just be you know

102
00:04:14,660 --> 00:04:12,330
it's the kind of thing that I grew up

103
00:04:17,630 --> 00:04:14,670
dreaming about when I was a kid and to

104
00:04:19,640 --> 00:04:17,640
get a chance to do that for real with my

105
00:04:21,440 --> 00:04:19,650
real life you know spirit made that
