1 00:00:04,430 --> 00:00:03,050 his earth unique in the solar system the 2 00:00:07,610 --> 00:00:04,440 only place where life could have taken 3 00:00:09,470 --> 00:00:07,620 hold or could such an environment have 4 00:00:11,150 --> 00:00:09,480 existed at some point on Mars where 5 00:00:12,890 --> 00:00:11,160 water and key chemical building blocks 6 00:00:14,839 --> 00:00:12,900 could have come together in a way that 7 00:00:17,720 --> 00:00:14,849 could support the smallest most basic 8 00:00:20,330 --> 00:00:17,730 forms of life the Mars Science 9 00:00:22,490 --> 00:00:20,340 Laboratory Rover NASA's new robotic 10 00:00:27,970 --> 00:00:22,500 vehicle for exploring Mars is heading to 11 00:00:33,530 --> 00:00:31,100 so how does a robotic Rome try to find 12 00:00:36,470 --> 00:00:33,540 answers by copying what its human 13 00:00:39,050 --> 00:00:36,480 creators give on earth geologists might 14 00:00:41,300 --> 00:00:39,060 check out a map drive out to a remote 15 00:00:43,100 --> 00:00:41,310 location and hike to a possibly 16 00:00:45,290 --> 00:00:43,110 hard-to-reach spot where they could see 17 00:00:47,330 --> 00:00:45,300 layers of ancient rocks like in the 18 00:00:50,299 --> 00:00:47,340 walls of a dried-up riverbed for the 19 00:00:52,250 --> 00:00:50,309 sides of a canyon MSL is an incredible 20 00:00:54,320 --> 00:00:52,260 Rover because it has an amazing ability 21 00:00:55,790 --> 00:00:54,330 to move around we're going to need that 22 00:01:00,290 --> 00:00:55,800 because we're going to have to go into 23 00:01:02,990 --> 00:01:00,300 some tough to reach places it can travel 24 00:01:04,430 --> 00:01:03,000 at least 20 kilometers probably further 25 00:01:06,050 --> 00:01:04,440 we're going to be able to land in a safe 26 00:01:08,240 --> 00:01:06,060 place and go beyond that to where the 27 00:01:10,130 --> 00:01:08,250 really rough rocks are which is where 28 00:01:11,420 --> 00:01:10,140 all the good geologic clues are to tell 29 00:01:14,510 --> 00:01:11,430 us about the early environmental 30 00:01:16,670 --> 00:01:14,520 evolution of Mars in the hunt for 31 00:01:18,320 --> 00:01:16,680 evidence of life on Mars geologists 32 00:01:20,780 --> 00:01:18,330 first have to determine if certain 33 00:01:22,880 --> 00:01:20,790 conditions were right the rock record 34 00:01:25,010 --> 00:01:22,890 shows evidence of certain minerals and 35 00:01:28,130 --> 00:01:25,020 organic molecules the chemical building 36 00:01:30,020 --> 00:01:28,140 blocks on which all life is based so 37 00:01:33,469 --> 00:01:30,030 what MSL would be able to do is it would 38 00:01:36,380 --> 00:01:33,479 it would drive up to this outcrop and it 39 00:01:39,200 --> 00:01:36,390 has a drill that's about a centimeter in 40 00:01:41,389 --> 00:01:39,210 diameter and we would instruct the rover 41 00:01:43,700 --> 00:01:41,399 to drill a hole in the rock and then the 42 00:01:47,060 --> 00:01:43,710 powder that comes out of that would then 43 00:01:48,950 --> 00:01:47,070 travel back into the rover and and it 44 00:01:51,050 --> 00:01:48,960 would be split and it would go into the 45 00:01:53,179 --> 00:01:51,060 two instruments that would analyze the 46 00:01:54,950 --> 00:01:53,189 powder when would give us information on 47 00:01:56,929 --> 00:01:54,960 mineralogy another one would give us 48 00:01:59,810 --> 00:01:56,939 information if there were any organic 49 00:02:00,919 --> 00:01:59,820 molecules in here so really as close as 50 00:02:03,499 --> 00:02:00,929 we can get to putting the field 51 00:02:05,419 --> 00:02:03,509 geologist on Mars and like any good 52 00:02:07,700 --> 00:02:05,429 geologist the Mars Science Laboratory 53 00:02:10,580 --> 00:02:07,710 Rover carries a full pack of gear for 54 00:02:13,340 --> 00:02:10,590 the trip on earth geologists use tools 55 00:02:15,470 --> 00:02:13,350 like compasses Rock hammers and hand 56 00:02:17,570 --> 00:02:15,480 lenses to explore the environment and 57 00:02:19,670 --> 00:02:17,580 study the rocks they might even do a 58 00:02:20,820 --> 00:02:19,680 simple acid test to see what the rocks 59 00:02:22,620 --> 00:02:20,830 are made of 60 00:02:24,570 --> 00:02:22,630 the Mars Science Laboratory Rover 61 00:02:26,550 --> 00:02:24,580 carries a whole laboratory with it 62 00:02:28,620 --> 00:02:26,560 wherever it goes it's much bigger than 63 00:02:30,750 --> 00:02:28,630 any Rover sent before about the size of 64 00:02:32,910 --> 00:02:30,760 a car that means it can carry a lot more 65 00:02:35,550 --> 00:02:32,920 advanced instruments we've got a laser 66 00:02:37,080 --> 00:02:35,560 called chemcam and we're going to be 67 00:02:39,540 --> 00:02:37,090 able to look at rocks that are on the 68 00:02:41,700 --> 00:02:39,550 walls of outcrops or in positions where 69 00:02:43,920 --> 00:02:41,710 we can't we can't really get to it and 70 00:02:45,540 --> 00:02:43,930 we'll be able to shoot this laser beam 71 00:02:47,640 --> 00:02:45,550 and look at the light that's reflected 72 00:02:49,620 --> 00:02:47,650 back to us and get some sense of the 73 00:02:51,810 --> 00:02:49,630 chemical composition of things that we 74 00:02:53,550 --> 00:02:51,820 might not be able to touch all these 75 00:02:55,230 --> 00:02:53,560 capabilities will help scientists 76 00:02:58,050 --> 00:02:55,240 understand the history of the remote 77 00:03:00,690 --> 00:02:58,060 areas one of the questions that people 78 00:03:02,490 --> 00:03:00,700 most often ask is whether or not life is 79 00:03:04,740 --> 00:03:02,500 unique in the universe in our solar 80 00:03:06,630 --> 00:03:04,750 system and the short answer to that is 81 00:03:08,310 --> 00:03:06,640 we don't really know and the only way 82 00:03:10,320 --> 00:03:08,320 we're going to figure this out is to 83 00:03:12,600 --> 00:03:10,330 leave our own planet and we'll explore 84 00:03:15,180 --> 00:03:12,610 other solar systems as well as planets 85 00:03:16,770 --> 00:03:15,190 within our own solar system could Mars 86 00:03:19,260 --> 00:03:16,780 have had an environment capable of 87 00:03:21,600 --> 00:03:19,270 supporting life the Mars Science 88 00:03:24,840 --> 00:03:21,610 Laboratory Rover is taking all the tools 89 00:03:26,610 --> 00:03:24,850 it needs to try to solve this mystery if 90 00:03:28,470 --> 00:03:26,620 all goes well at the end of its journey 91 00:03:30,380 --> 00:03:28,480 the rover will have taken us to places 92 00:03:32,460 --> 00:03:30,390 on Mars we could never reach before 93 00:03:34,560 --> 00:03:32,470 giving us a glimpse back into the 94 00:03:36,960 --> 00:03:34,570 history of the planet and maybe even
