1
00:00:14,320 --> 00:00:12,730
Phoenix is a mission to land near the

2
00:00:16,900 --> 00:00:14,330
North Pole Amar's kind of up in the

3
00:00:18,520 --> 00:00:16,910
Arctic Circle area we're in an area

4
00:00:20,680 --> 00:00:18,530
where the Sun doesn't get very high in

5
00:00:22,780 --> 00:00:20,690
the sky where the summer isn't very long

6
00:00:24,940 --> 00:00:22,790
and it's that type of environment that

7
00:00:25,420 --> 00:00:24,950
actually Foster is what we're going to

8
00:00:27,430 --> 00:00:25,430
study

9
00:00:31,240 --> 00:00:27,440
it's believed from Mars Odyssey data

10
00:00:33,490 --> 00:00:31,250
that there is water ice or frozen ice

11
00:00:34,990 --> 00:00:33,500
near the pull of Mars that we can

12
00:00:37,930 --> 00:00:35,000
actually go down with our robotic arm

13
00:00:39,670 --> 00:00:37,940
and sample directly in the north polar

14
00:00:43,030 --> 00:00:39,680
region outside of the polar caps that we

15
00:00:44,980 --> 00:00:43,040
see there actually is maybe up to 80

16
00:00:48,729 --> 00:00:44,990
percent water in the top meter of the

17
00:00:50,140 --> 00:00:48,739
soil so our job is to dig deep not to

18
00:00:51,760 --> 00:00:50,150
drive out like some of the rover's have

19
00:00:53,620 --> 00:00:51,770
done in the past and so we have the

20
00:00:55,690 --> 00:00:53,630
robotic arm with its scoop onboard our

21
00:00:57,340 --> 00:00:55,700
spacecraft to sample the dirt on the top

22
00:00:59,670 --> 00:00:57,350
and dig down and sample the ice and

23
00:01:03,460 --> 00:00:59,680
deliver those to the onboard experiments

24
00:01:06,160 --> 00:01:03,470
we're hoping that we can learn more

25
00:01:09,129 --> 00:01:06,170
about the long-term climate of Mars by

26
00:01:12,550 --> 00:01:09,139
looking at the ice we're hoping to

27
00:01:13,779 --> 00:01:12,560
understand more about the polar regions

28
00:01:17,289 --> 00:01:13,789
of Mars which is a place we've never

29
00:01:19,989 --> 00:01:17,299
gone to and finally we're really

30
00:01:22,289 --> 00:01:19,999
interested in looking for a habitable

31
00:01:25,359 --> 00:01:22,299
zone a place where life might have

32
00:01:28,629 --> 00:01:25,369
existed in the past if you get to a

33
00:01:30,819 --> 00:01:28,639
place where there's ice for instance you

34
00:01:32,139 --> 00:01:30,829
wonder if over time the climate could

35
00:01:34,959 --> 00:01:32,149
have changed the point where that ice

36
00:01:37,469 --> 00:01:34,969
melted now if you have liquid water and

37
00:01:40,300 --> 00:01:37,479
you have soil and you have sunlight

38
00:01:42,519 --> 00:01:40,310
you've got a lot of the ingredients not

39
00:01:45,039 --> 00:01:42,529
all but a lot of the ingredients that

40
00:01:48,279 --> 00:01:45,049
can lead to a place where life could

41
00:01:50,769 --> 00:01:48,289
actually take a foothold and we call

42
00:01:53,050 --> 00:01:50,779
that the habitability of the soil

43
00:01:55,179 --> 00:01:53,060
now whether life actually did take that

44
00:01:57,129 --> 00:01:55,189
foothold and whether the one place we

45
00:02:00,580 --> 00:01:57,139
land actually contains that life is a

46
00:02:02,409 --> 00:02:00,590
different question so this is not an

47
00:02:03,830 --> 00:02:02,419
easy search and our goals are a little

48
00:02:06,440 --> 00:02:03,840
more limited than

49
00:02:09,050 --> 00:02:06,450
we must find life we will find if that

50
00:02:11,240 --> 00:02:09,060
zone is habitable and if it is then we

51
00:02:14,449 --> 00:02:11,250
would suggest to the community this is a

52
00:02:16,430 --> 00:02:14,459
good place to go and look for life I'm

53
00:02:17,990 --> 00:02:16,440
very excited about Phoenix I came from

54
00:02:20,059 --> 00:02:18,000
the Mars exploration Rovers and that was

55
00:02:22,430 --> 00:02:20,069
a very different kind of mission em er

56
00:02:24,440 --> 00:02:22,440
was all about driving about roving about

57
00:02:26,600 --> 00:02:24,450
going up to rocks and grinding through

58
00:02:28,339 --> 00:02:26,610
them the science that Phoenix needs to

59
00:02:30,530 --> 00:02:28,349
do is a very different type of science I

60
00:02:31,520 --> 00:02:30,540
think of em er as the scratch-and-sniff

61
00:02:33,650 --> 00:02:31,530
mission

62
00:02:36,259 --> 00:02:33,660
whereas Phoenix is really the the

63
00:02:38,270 --> 00:02:36,269
grabbed in each mission we have science

64
00:02:41,449 --> 00:02:38,280
instruments that are designed to ingest

65
00:02:44,089 --> 00:02:41,459
soil and it gives you really a kind of a

66
00:02:45,380 --> 00:02:44,099
laboratory class knowledge of the

67
00:02:47,270 --> 00:02:45,390
surface of Mars which is something that

68
00:02:50,180 --> 00:02:47,280
Meor with the instruments that it had

69
00:02:52,880 --> 00:02:50,190
wasn't able to do so while Phoenix has

70
00:02:54,860 --> 00:02:52,890
its limitations in terms of mobility and
