1
00:00:07,760 --> 00:00:06,110
I was one of the optimists that felt the

2
00:00:09,950 --> 00:00:07,770
rover's would survive the first winter

3
00:00:11,990 --> 00:00:09,960
and that we would have an extended

4
00:00:14,560 --> 00:00:12,000
mission but I never thought they would

5
00:00:17,990 --> 00:00:14,570
last through three Martian winters and

6
00:00:19,849 --> 00:00:18,000
continue to explore for five years we

7
00:00:21,019 --> 00:00:19,859
thought that you know we we were going

8
00:00:23,029 --> 00:00:21,029
to be lucky if we got three months out

9
00:00:24,620 --> 00:00:23,039
of these Rovers we've got five years out

10
00:00:26,630 --> 00:00:24,630
of these Rovers and they just keep going

11
00:00:28,130 --> 00:00:26,640
and it seems like every day is better

12
00:00:29,179 --> 00:00:28,140
than the day before the mission just

13
00:00:30,950 --> 00:00:29,189
keeps getting better and better and

14
00:00:32,269 --> 00:00:30,960
better the longer it goes how do I feel

15
00:00:39,160 --> 00:00:32,279
about the fact that it's going on for

16
00:00:43,400 --> 00:00:41,840
everyone on the planet Earth is sharing

17
00:00:46,160 --> 00:00:43,410
in the experience of exploring the

18
00:00:48,200 --> 00:00:46,170
surface of Mars through our to surrogate

19
00:00:51,860 --> 00:00:48,210
children Spirit and Opportunity you're

20
00:00:53,119 --> 00:00:51,870
seeing Mars with 3d color stereo vision

21
00:00:54,740 --> 00:00:53,129
just as if you were standing there

22
00:00:56,540 --> 00:00:54,750
yourself the rover's are just about your

23
00:00:58,279 --> 00:00:56,550
height and so they see the world from

24
00:00:59,869 --> 00:00:58,289
your perspective and just as you would

25
00:01:02,479 --> 00:00:59,879
see it if you were there now they are

26
00:01:04,369 --> 00:01:02,489
well-named opportunity really has been

27
00:01:06,440 --> 00:01:04,379
incredibly opportunistic and lucky it

28
00:01:08,450 --> 00:01:06,450
basically found water from its Lander

29
00:01:10,370 --> 00:01:08,460
found its own heat shield we were able

30
00:01:11,750 --> 00:01:10,380
to examine for the first time a heat

31
00:01:14,539 --> 00:01:11,760
shield that was used on another planet

32
00:01:16,550 --> 00:01:14,549
cuz it happened to land nearby spirit

33
00:01:20,240 --> 00:01:16,560
really has had to have a lot of spirit

34
00:01:23,240 --> 00:01:20,250
to to keep going when we were hit by

35
00:01:24,859 --> 00:01:23,250
dust storms we get cleaned off and

36
00:01:26,570 --> 00:01:24,869
that's what's enabled or over to survive

37
00:01:27,649 --> 00:01:26,580
this long when we broke the right front

38
00:01:29,960 --> 00:01:27,659
wheel we've made one of the major

39
00:01:32,120 --> 00:01:29,970
scientific discoveries by dragging this

40
00:01:34,010 --> 00:01:32,130
wheel behind us we're digging this

41
00:01:35,210 --> 00:01:34,020
trench and we're seeing what's under the

42
00:01:36,360 --> 00:01:35,220
surface and what we're finding

43
00:01:38,640 --> 00:01:36,370
everywhere

44
00:01:41,460 --> 00:01:38,650
look are these salts and minerals like

45
00:01:45,260 --> 00:01:41,470
silicon and sulfur that had to have been

46
00:01:49,050 --> 00:01:45,270
put there by hot water this last winter

47
00:01:51,660 --> 00:01:49,060
when we had to park for more than nine

48
00:01:53,820 --> 00:01:51,670
months in the same location because we

49
00:01:56,280 --> 00:01:53,830
just didn't have enough power to to

50
00:01:58,950 --> 00:01:56,290
drive the one thing we could still do

51
00:02:00,870 --> 00:01:58,960
was take pictures and we did take over

52
00:02:04,050 --> 00:02:00,880
the course of many many weeks sort of

53
00:02:07,260 --> 00:02:04,060
one frame at a time this beautiful

54
00:02:09,840 --> 00:02:07,270
high-resolution full-color image of the

55
00:02:12,000 --> 00:02:09,850
location around spirit and it's one of

56
00:02:15,860 --> 00:02:12,010
the most detailed highest resolution

57
00:02:18,890 --> 00:02:15,870
images we've ever taken from the ground

58
00:02:24,090 --> 00:02:18,900
get the victoria was great I mean it was

59
00:02:25,980 --> 00:02:24,100
21 months of trudging endlessly across

60
00:02:28,500 --> 00:02:25,990
these Plains and hardly seeing the

61
00:02:29,820 --> 00:02:28,510
scenery change at all I mean you know

62
00:02:31,410 --> 00:02:29,830
Victoria is out there we've got the

63
00:02:33,300 --> 00:02:31,420
orbital images we know where it is we

64
00:02:36,000 --> 00:02:33,310
know how far it is room measuring

65
00:02:38,990 --> 00:02:36,010
distance to the nearest meter and then

66
00:02:42,750 --> 00:02:39,000
one day we're right at the rim of it

67
00:02:44,820 --> 00:02:42,760
there's just this spectacular scenery

68
00:02:48,780 --> 00:02:44,830
this fabulous geology laid out in front

69
00:02:51,750 --> 00:02:48,790
of us and yeah the combination of just

70
00:02:53,280 --> 00:02:51,760
what a glorious view it was plus how so

71
00:02:55,949 --> 00:02:53,290
much effort that went into getting there

72
00:02:57,570 --> 00:02:55,959
pulling up to the rim of Victoria was to

73
00:03:00,930 --> 00:02:57,580
me one really special moments in the

74
00:03:02,820 --> 00:03:00,940
whole measure one of the most memorable

75
00:03:05,880 --> 00:03:02,830
and poetic images from the entire

76
00:03:08,100 --> 00:03:05,890
mission is an image that spirit took of

77
00:03:10,199 --> 00:03:08,110
the earth it was a very first picture

78
00:03:12,570 --> 00:03:10,209
that has ever been taken of the earth

79
00:03:14,930 --> 00:03:12,580
from the surface of another planet earth

80
00:03:17,210 --> 00:03:14,940
is the evening star

81
00:03:19,460 --> 00:03:17,220
mars is such a complicated place and

82
00:03:23,170 --> 00:03:19,470
these are such capable vehicles that

83
00:03:25,460 --> 00:03:23,180
they will never come a time we've done

84
00:03:27,680 --> 00:03:25,470
regardless of weather when this mission

85
00:03:30,910 --> 00:03:27,690
ends whether it's tomorrow or five years

86
00:03:34,010 --> 00:03:30,920
from now there's always going to be some
