1
00:00:06,470 --> 00:00:03,909
after six years of unprecedented science

2
00:00:09,030 --> 00:00:06,480
exploration this month the mars spirit

3
00:00:10,790 --> 00:00:09,040
rover is now designated a stationary

4
00:00:13,110 --> 00:00:10,800
science platform

5
00:00:15,270 --> 00:00:13,120
efforts to free itself from a sand trap

6
00:00:16,710 --> 00:00:15,280
over the past several months have been

7
00:00:19,349 --> 00:00:16,720
unsuccessful

8
00:00:21,590 --> 00:00:19,359
now the venerable robot's primary task

9
00:00:24,870 --> 00:00:21,600
will be to position itself to combat the

10
00:00:26,950 --> 00:00:24,880
severe martian winter if spirit survives

11
00:00:29,029 --> 00:00:26,960
it will continue conducting significant

12
00:00:32,069 --> 00:00:29,039
new science for several months or

13
00:00:34,389 --> 00:00:32,079
perhaps years in its new fixed location

14
00:00:36,709 --> 00:00:34,399
spirit stationary science priorities

15
00:00:37,910 --> 00:00:36,719
right now appear first will be radio

16
00:00:48,150 --> 00:00:37,920
science

17
00:00:51,110 --> 00:00:48,160
involves trying to understand what the

18
00:00:53,670 --> 00:00:51,120
composition and the size of the planet's

19
00:00:56,229 --> 00:00:53,680
core is which has a direct correlation

20
00:00:58,549 --> 00:00:56,239
to the history of the planet the change

21
00:01:00,950 --> 00:00:58,559
in the climate that occurred on mars and

22
00:01:02,869 --> 00:01:00,960
why mars has gone from a warm wet place

23
00:01:06,230 --> 00:01:02,879
that three and a half four billion years

24
00:01:08,550 --> 00:01:06,240
ago resembled earth to the dry barren uh

25
00:01:10,710 --> 00:01:08,560
planet that it is today on the other

26
00:01:13,670 --> 00:01:10,720
side of the planet spirit's sister rover

27
00:01:15,990 --> 00:01:13,680
opportunity continues to move well right

28
00:01:18,630 --> 00:01:16,000
now it treks from victoria to endeavor

29
00:01:20,149 --> 00:01:18,640
crater exploring as it goes it has found

30
00:01:22,230 --> 00:01:20,159
meteorites on the surface that we've

31
00:01:24,469 --> 00:01:22,240
investigated it's found sand dunes that

32
00:01:26,550 --> 00:01:24,479
we've investigated and driven over and

33
00:01:29,670 --> 00:01:26,560
it's only recently found what appears to

34
00:01:31,910 --> 00:01:29,680
be a very new crater called concepcion

35
00:01:33,350 --> 00:01:31,920
that may be in geological terms brand

36
00:01:35,429 --> 00:01:33,360
new maybe is

37
00:01:37,350 --> 00:01:35,439
maybe as new as a thousand years old

38
00:01:39,990 --> 00:01:37,360
spirit and opportunity began missions

39
00:01:43,190 --> 00:01:40,000
intended to last for three months spirit
