1 00:00:11,430 --> 00:00:21,590 [Music] 2 00:00:27,429 --> 00:00:24,870 my name is precious hypatia and my dream 3 00:00:29,509 --> 00:00:27,439 is to become an astronaut 4 00:00:31,420 --> 00:00:29,519 i love to explore 5 00:00:37,590 --> 00:00:31,430 and i love to dance 6 00:00:41,110 --> 00:00:37,600 [Music] 7 00:00:42,310 --> 00:00:41,120 i want to explore more soil seas or even 8 00:00:44,709 --> 00:00:42,320 planets 9 00:00:47,430 --> 00:00:44,719 it's in our very dna to explore more 10 00:00:50,069 --> 00:00:47,440 about our world and the unknown 11 00:00:52,310 --> 00:00:50,079 we are a curious species 12 00:00:53,670 --> 00:00:52,320 that's why i always wonder 13 00:00:56,069 --> 00:00:53,680 what's out there 14 00:00:58,470 --> 00:00:56,079 beyond space 15 00:01:01,270 --> 00:00:58,480 though some time ago the dinosaurs were 16 00:01:03,270 --> 00:01:01,280 vanished by an asteroid from the space 17 00:01:05,670 --> 00:01:03,280 what if that happens again 18 00:01:06,950 --> 00:01:05,680 that's going to end my dream 19 00:01:08,550 --> 00:01:06,960 my friends 20 00:01:11,190 --> 00:01:08,560 and my family 21 00:01:12,630 --> 00:01:11,200 a large asteroid could wipe us out 22 00:01:15,030 --> 00:01:12,640 forever 23 00:01:17,590 --> 00:01:15,040 but it won't happen because we are going 24 00:01:19,749 --> 00:01:17,600 to venture to mars 25 00:01:23,030 --> 00:01:19,759 but why mars 26 00:01:26,149 --> 00:01:23,040 to survive we have to reach beyond earth 27 00:01:28,469 --> 00:01:26,159 mars often described as the red planet 28 00:01:30,870 --> 00:01:28,479 is the fourth planet from the sun named 29 00:01:33,510 --> 00:01:30,880 after the roman god of war 30 00:01:35,990 --> 00:01:33,520 mars isn't exactly earth-like but it's 31 00:01:38,469 --> 00:01:36,000 by far the most livable other place in 32 00:01:41,030 --> 00:01:38,479 our entire solar system 33 00:01:42,950 --> 00:01:41,040 though we can't live there yet 34 00:01:44,789 --> 00:01:42,960 even more challenging is 35 00:01:45,910 --> 00:01:44,799 how do we get there 36 00:01:48,870 --> 00:01:45,920 well 37 00:01:51,670 --> 00:01:48,880 we have the orion spacecraft 38 00:01:54,550 --> 00:01:51,680 the orion multi-purpose crew vehicle is 39 00:01:57,190 --> 00:01:54,560 an interplanetary spacecraft intended to 40 00:02:01,190 --> 00:01:57,200 facilitate human exploration of the moon 41 00:02:03,350 --> 00:02:01,200 asteroids and of mars mars is 250 42 00:02:05,590 --> 00:02:03,360 million miles away and it will take us 43 00:02:08,229 --> 00:02:05,600 nine months to get there if we launch on 44 00:02:10,070 --> 00:02:08,239 a very specific day and time once every 45 00:02:12,309 --> 00:02:10,080 two years when mars and earth are 46 00:02:14,710 --> 00:02:12,319 perfectly aligned just so the distance 47 00:02:17,990 --> 00:02:14,720 will be the shortest once we get there 48 00:02:20,790 --> 00:02:18,000 we need water oxygen food shelter and 49 00:02:24,150 --> 00:02:20,800 clothing this device is a dehumidifier 50 00:02:26,309 --> 00:02:24,160 mars's atmosphere is often 100 humid so 51 00:02:28,790 --> 00:02:26,319 this device can extract water simply 52 00:02:31,990 --> 00:02:28,800 from mars atmosphere now how do we 53 00:02:34,390 --> 00:02:32,000 breathe michael hecht a scientist at mit 54 00:02:36,470 --> 00:02:34,400 developed a reverse fuel cell that sucks 55 00:02:39,509 --> 00:02:36,480 in the martian atmosphere and pumps out 56 00:02:41,589 --> 00:02:39,519 oxygen next what will we eat once we get 57 00:02:44,070 --> 00:02:41,599 enough water we'll use hydroponics to 58 00:02:46,470 --> 00:02:44,080 grow food and then we need some shelter 59 00:02:48,630 --> 00:02:46,480 at first we can use inflatable 60 00:02:50,869 --> 00:02:48,640 pressurized buildings as well as our 61 00:02:53,670 --> 00:02:50,879 landers later on we have to go 62 00:02:55,830 --> 00:02:53,680 underground lava tubes caves or build 63 00:02:57,990 --> 00:02:55,840 buildings with really thick walls for 64 00:03:00,790 --> 00:02:58,000 our protection against radiation and 65 00:03:03,030 --> 00:03:00,800 cosmic rays and finally our clothing on 66 00:03:05,910 --> 00:03:03,040 mars there's hardly any atmospheric 67 00:03:08,390 --> 00:03:05,920 pressure so dava newman a scientist at 68 00:03:10,949 --> 00:03:08,400 mit has created a spacesuit that will 69 00:03:12,790 --> 00:03:10,959 keep us together block harmful radiation 70 00:03:15,509 --> 00:03:12,800 and keep us warm 71 00:03:16,710 --> 00:03:15,519 overall it's still very complicated and 72 00:03:19,110 --> 00:03:16,720 difficult 73 00:03:21,509 --> 00:03:19,120 so that leads to the next big step and 74 00:03:23,990 --> 00:03:21,519 that's terraforming the planet 75 00:03:27,190 --> 00:03:24,000 making it earth-like we can now be a 76 00:03:29,830 --> 00:03:27,200 multi-planet species 77 00:03:31,270 --> 00:03:29,840 going to mars is the realization of an 78 00:03:33,670 --> 00:03:31,280 awesome dream 79 00:03:36,070 --> 00:03:33,680 we've all been curious all this time 80 00:03:39,030 --> 00:03:36,080 what happened to mars is there life on 81 00:03:41,990 --> 00:03:39,040 mars sending people to mars is the next 82 00:03:43,350 --> 00:03:42,000 giant leap for mankind 83 00:03:46,789 --> 00:03:43,360 while it's true that there are 84 00:03:49,430 --> 00:03:46,799 challenges to face anything is possible 85 00:03:52,390 --> 00:03:49,440 the human race is a species of explorers 86 00:03:53,910 --> 00:03:52,400 and pioneers that forge bravely into the 87 00:03:55,750 --> 00:03:53,920 unknown 88 00:03:57,589 --> 00:03:55,760 where would we be if we hadn't learned 89 00:04:00,550 --> 00:03:57,599 to navigate the seas and spread our 90 00:04:02,229 --> 00:04:00,560 descendants throughout the globe we are 91 00:04:05,110 --> 00:04:02,239 the only species that has the 92 00:04:08,869 --> 00:04:05,120 instinctive need to travel expand 93 00:04:12,229 --> 00:04:08,879 explore regardless of the consequences 94 00:04:14,710 --> 00:04:12,239 and that makes us who we are 95 00:04:16,710 --> 00:04:14,720 all this is just the next step in our 96 00:04:18,949 --> 00:04:16,720 journey as a species 97 00:04:21,909 --> 00:04:18,959 and it's an important one 98 00:04:25,990 --> 00:04:21,919 yes there will be some challenges 99 00:04:30,950 --> 00:04:28,550 i am going to be an astronaut and i will 100 00:04:36,830 --> 00:04:30,960 be the first dancer to step on martian 101 00:04:47,990 --> 00:04:43,890 [Music]
