1 00:00:03,750 --> 00:00:01,429 [Music] 2 00:00:05,749 --> 00:00:03,760 sometimes you have to do something just 3 00:00:07,749 --> 00:00:05,759 to show that you can do it 4 00:00:08,870 --> 00:00:07,759 when the wright brothers flew for the 5 00:00:11,669 --> 00:00:08,880 first time they do 6 00:00:12,150 --> 00:00:11,679 an experimental aircraft and in the same 7 00:00:13,830 --> 00:00:12,160 way 8 00:00:15,190 --> 00:00:13,840 the mars helicopter is designed to show 9 00:00:17,189 --> 00:00:15,200 that we can fly 10 00:00:24,870 --> 00:00:17,199 and helicopter flight in the martian 11 00:00:28,630 --> 00:00:27,349 from day one this was the unwavering 12 00:00:31,830 --> 00:00:28,640 dream of our team 13 00:00:33,830 --> 00:00:31,840 to get our helicopter launched to mars 14 00:00:36,709 --> 00:00:33,840 so that we can get that opportunity to 15 00:00:39,430 --> 00:00:36,719 do the very first rotograph flight test 16 00:00:40,869 --> 00:00:39,440 in the actual environment of mars it's 17 00:00:44,150 --> 00:00:40,879 extremely difficult to 18 00:00:45,110 --> 00:00:44,160 fly at mars because is so thin compared 19 00:00:47,190 --> 00:00:45,120 to earth 20 00:00:49,270 --> 00:00:47,200 at mars it's less than one percent so 21 00:00:51,670 --> 00:00:49,280 the first and foremost challenge is 22 00:00:52,470 --> 00:00:51,680 to make a vehicle that's light enough to 23 00:00:54,869 --> 00:00:52,480 be lifted 24 00:00:57,270 --> 00:00:54,879 and then the second is to generate lift 25 00:00:58,389 --> 00:00:57,280 the rotor system is to spin very fast 26 00:01:00,790 --> 00:00:58,399 two thousand 27 00:01:02,630 --> 00:01:00,800 twenty two hundred twenty four hundred 28 00:01:04,549 --> 00:01:02,640 twenty six hundred we're spinning 29 00:01:06,310 --> 00:01:04,559 between two thousand and three thousand 30 00:01:07,270 --> 00:01:06,320 revolutions per minute and it takes a 31 00:01:09,750 --> 00:01:07,280 lot of energy 32 00:01:10,789 --> 00:01:09,760 so it's that balance of a very light 33 00:01:13,750 --> 00:01:10,799 system 34 00:01:14,230 --> 00:01:13,760 yet having enough energy that's needed 35 00:01:24,710 --> 00:01:14,240 to 36 00:01:26,469 --> 00:01:24,720 time it takes off the time it lands 37 00:01:28,469 --> 00:01:26,479 what we do do on the ground is we plan 38 00:01:29,109 --> 00:01:28,479 the flights and so we determine from 39 00:01:37,030 --> 00:01:29,119 here 40 00:01:40,469 --> 00:01:37,040 our experiment window is 30 martian days 41 00:01:43,749 --> 00:01:40,479 so we have planned up to five flights 42 00:01:44,550 --> 00:01:43,759 of incremental difficulty very first 43 00:01:46,149 --> 00:01:44,560 flight the 44 00:01:48,310 --> 00:01:46,159 main thing is we want to get the legs 45 00:01:51,429 --> 00:01:48,320 off the ground and so we will 46 00:01:52,870 --> 00:01:51,439 basically go up about three meters and 47 00:01:54,789 --> 00:01:52,880 we'll hover there 48 00:01:56,389 --> 00:01:54,799 and then we'll come down again and that 49 00:01:59,190 --> 00:01:56,399 will be the first you know really 50 00:02:00,870 --> 00:01:59,200 major milestone most of our flights will 51 00:02:02,950 --> 00:02:00,880 be at the three to five meter height 52 00:02:04,310 --> 00:02:02,960 we will be going horizontally again at a 53 00:02:06,630 --> 00:02:04,320 few meters per second 54 00:02:07,590 --> 00:02:06,640 probably go out you know 50 70 meters 55 00:02:09,270 --> 00:02:07,600 and come back in 56 00:02:10,949 --> 00:02:09,280 successive flights we'll probably push 57 00:02:13,030 --> 00:02:10,959 that further try to go further 58 00:02:14,949 --> 00:02:13,040 so our priority will be to get back 59 00:02:15,589 --> 00:02:14,959 engineering telemetry and not so much 60 00:02:17,350 --> 00:02:15,599 images 61 00:02:20,309 --> 00:02:17,360 but i'm sure we'll return a few you know 62 00:02:23,030 --> 00:02:20,319 because they'll always look cool 63 00:02:23,670 --> 00:02:23,040 at this point we've tested all we can on 64 00:02:25,830 --> 00:02:23,680 earth 65 00:02:27,830 --> 00:02:25,840 we have mathematical models that shows 66 00:02:28,229 --> 00:02:27,840 how it will fly at mars and we've tested 67 00:02:30,470 --> 00:02:28,239 it 68 00:02:31,910 --> 00:02:30,480 in the simulated environment that we can 69 00:02:34,790 --> 00:02:31,920 create on earth 70 00:02:36,470 --> 00:02:34,800 it really is time now to do the real 71 00:02:38,630 --> 00:02:36,480 flood types at mars 72 00:02:40,630 --> 00:02:38,640 nothing is a given but we have done 73 00:02:42,390 --> 00:02:40,640 everything we can in terms of a test 74 00:02:44,229 --> 00:02:42,400 program here on earth the vehicle is 75 00:02:45,830 --> 00:02:44,239 performing extremely well so far it's 76 00:02:47,509 --> 00:02:45,840 been doing exactly the right thing 77 00:02:49,190 --> 00:02:47,519 even right now and is bolted onto the 78 00:02:50,390 --> 00:02:49,200 perseverance rover so 79 00:02:53,589 --> 00:02:50,400 there's a very good chance that we'll 80 00:02:56,229 --> 00:02:53,599 pull it off yes but it's still high risk 81 00:02:57,350 --> 00:02:56,239 and none of us forget that you could 82 00:02:59,990 --> 00:02:57,360 have a glitch that 83 00:03:00,949 --> 00:03:00,000 you know could mean end of mission yes 84 00:03:03,990 --> 00:03:00,959 it's going to be 85 00:03:07,430 --> 00:03:04,000 exciting reacting to any surprises 86 00:03:10,630 --> 00:03:09,190 what's really most important is 87 00:03:13,750 --> 00:03:10,640 everything we're learning here 88 00:03:16,830 --> 00:03:13,760 is for the future roto craft systems
