1
00:00:11,480 --> 00:00:08,960
we're here in our test facility at JPL

2
00:00:14,419 --> 00:00:11,490
trying to help spirit on the surface of

3
00:00:17,000 --> 00:00:14,429
Mars spirit had become embedded in loose

4
00:00:19,340 --> 00:00:17,010
soft material in the rover is having

5
00:00:21,410 --> 00:00:19,350
difficulty extracting herself so what

6
00:00:23,150 --> 00:00:21,420
we've done since we can't send people to

7
00:00:25,400 --> 00:00:23,160
Mars to help the rover's we're bringing

8
00:00:27,679 --> 00:00:25,410
Mars down here to earth so we're in the

9
00:00:29,710 --> 00:00:27,689
process of recreating the conditions

10
00:00:32,810 --> 00:00:29,720
where spirit is stuck in this facility

11
00:00:35,930 --> 00:00:32,820
the soil where spirit has trouble moving

12
00:00:38,479 --> 00:00:35,940
is a very light fluffy material so what

13
00:00:40,580 --> 00:00:38,489
we've done is developed a simulant here

14
00:00:43,400 --> 00:00:40,590
at JPL from a constituent of different

15
00:00:44,900 --> 00:00:43,410
materials and we're creating that

16
00:00:47,690 --> 00:00:44,910
material producing mixing it and

17
00:00:50,090 --> 00:00:47,700
spreading it in our test box here and

18
00:00:51,950 --> 00:00:50,100
then conditioning the soil landscaping

19
00:00:54,229 --> 00:00:51,960
it if you will to be just like the

20
00:00:56,119 --> 00:00:54,239
terrain on Mars and then we'll take our

21
00:00:58,430 --> 00:00:56,129
engineering Rover which is just like

22
00:01:00,580 --> 00:00:58,440
spirit the exact same size it will put

23
00:01:03,200 --> 00:01:00,590
our engineering Rover into this facility

24
00:01:05,050 --> 00:01:03,210
deliberately embed it in the facility

25
00:01:07,399 --> 00:01:05,060
the same way spirit is stock and then

26
00:01:09,440 --> 00:01:07,409
experiment with extracting trying to get

27
00:01:11,840 --> 00:01:09,450
the rover out try to figure out what

28
00:01:13,850 --> 00:01:11,850
works here before we do it for real on

29
00:01:16,190 --> 00:01:13,860
Mars because there's always the risk

30
00:01:18,020 --> 00:01:16,200
that something we may try actually might

31
00:01:20,030 --> 00:01:18,030
make things worse and we want to avoid

32
00:01:22,160 --> 00:01:20,040
that so we want to find out what things

33
00:01:23,780 --> 00:01:22,170
work what doesn't avoid the things that

34
00:01:26,990 --> 00:01:23,790
don't work and then focus on the things

35
00:01:29,210 --> 00:01:27,000
that do work we expect that it will take

36
00:01:32,569 --> 00:01:29,220
some time for us to complete the testing

37
00:01:35,030 --> 00:01:32,579
here at JPL and then to actually extract

38
00:01:36,890 --> 00:01:35,040
spirit on the surface of Mars so we will

39
00:01:38,569 --> 00:01:36,900
be regularly updating you on the

40
00:01:41,090 --> 00:01:38,579
progress both here on the ground and on

41
00:01:42,710 --> 00:01:41,100
the surface of Mars I'm Jon Callas
