1 00:00:16,470 --> 00:00:14,390 [Music] 2 00:00:18,470 --> 00:00:16,480 when you look up at the night sky do you 3 00:00:19,429 --> 00:00:18,480 ever wonder how we might visit another 4 00:00:21,109 --> 00:00:19,439 planet 5 00:00:23,189 --> 00:00:21,119 like mars 6 00:00:25,109 --> 00:00:23,199 researchers at nasa have been working on 7 00:00:26,550 --> 00:00:25,119 humankind's journey to the red planet 8 00:00:28,470 --> 00:00:26,560 for decades 9 00:00:30,950 --> 00:00:28,480 over the years they've sent a number of 10 00:00:33,430 --> 00:00:30,960 spacecraft orbitals rovers and 11 00:00:36,950 --> 00:00:33,440 satellites into space giving us a look 12 00:00:38,709 --> 00:00:36,960 into what lies far far beyond our reach 13 00:00:40,869 --> 00:00:38,719 but the furthest humans have traveled is 14 00:00:43,110 --> 00:00:40,879 only to the other side of the moon 15 00:00:45,910 --> 00:00:43,120 venturing deeper into space has posed a 16 00:00:47,750 --> 00:00:45,920 number of new challenges 17 00:00:49,350 --> 00:00:47,760 how will nasa astronaut crew live in 18 00:00:51,910 --> 00:00:49,360 space 19 00:00:53,350 --> 00:00:51,920 will their health change 20 00:00:55,910 --> 00:00:53,360 what happens in the event of an 21 00:00:57,510 --> 00:00:55,920 emergency 22 00:00:59,270 --> 00:00:57,520 and what will they do when they get to 23 00:01:01,029 --> 00:00:59,280 mars anyway 24 00:01:03,029 --> 00:01:01,039 questions like these have made planning 25 00:01:04,869 --> 00:01:03,039 the trip a difficult task 26 00:01:06,870 --> 00:01:04,879 but it isn't impossible 27 00:01:09,109 --> 00:01:06,880 nasa has come up with a unique way to 28 00:01:12,310 --> 00:01:09,119 connect the dots between earth and mars 29 00:01:15,109 --> 00:01:12,320 through a series of stepping stones this 30 00:01:17,590 --> 00:01:15,119 special route to mars called ares 31 00:01:20,149 --> 00:01:17,600 arriving realistically to earth's sister 32 00:01:22,789 --> 00:01:20,159 details a complex celestial dance with 33 00:01:24,550 --> 00:01:22,799 nasa spacecraft technology and none of 34 00:01:26,630 --> 00:01:24,560 it would be possible without the main 35 00:01:28,149 --> 00:01:26,640 transportation vehicle 36 00:01:33,350 --> 00:01:28,159 orion 37 00:01:35,510 --> 00:01:33,360 designed to carry nasa astronaut crew to 38 00:01:38,310 --> 00:01:35,520 and from mars 39 00:01:41,350 --> 00:01:38,320 it is composed of three main parts the 40 00:01:43,510 --> 00:01:41,360 launch abort system the crew module and 41 00:01:44,950 --> 00:01:43,520 the service module 42 00:01:46,870 --> 00:01:44,960 astronauts will travel in the crew 43 00:01:48,950 --> 00:01:46,880 module when orion carries humans from 44 00:01:50,230 --> 00:01:48,960 earth and along the stepping stones to 45 00:01:52,230 --> 00:01:50,240 mars 46 00:01:54,550 --> 00:01:52,240 but it won't travel alone 47 00:01:58,149 --> 00:01:54,560 orion is lucky to have some help from a 48 00:02:01,990 --> 00:02:00,389 the space launch system is a heavy lift 49 00:02:04,310 --> 00:02:02,000 launch rocket that will help build the 50 00:02:07,670 --> 00:02:04,320 stepping stones for aries by carrying 51 00:02:10,070 --> 00:02:07,680 large quantities of materials into space 52 00:02:13,190 --> 00:02:10,080 eventually it will also launch orion off 53 00:02:15,190 --> 00:02:13,200 earth and beyond low earth orbit 54 00:02:17,110 --> 00:02:15,200 the lunar orbital platform gateway is a 55 00:02:18,309 --> 00:02:17,120 working space station that encircles the 56 00:02:20,150 --> 00:02:18,319 moon 57 00:02:22,229 --> 00:02:20,160 the lunar orbital platform gateway will 58 00:02:24,309 --> 00:02:22,239 provide a habitation system docking 59 00:02:27,110 --> 00:02:24,319 capabilities and technical support for 60 00:02:28,949 --> 00:02:27,120 future space missions for orion it will 61 00:02:32,070 --> 00:02:28,959 be where the crew module will join and 62 00:02:33,910 --> 00:02:32,080 connect with the deep space transport 63 00:02:35,509 --> 00:02:33,920 the deep space transport will carry 64 00:02:38,630 --> 00:02:35,519 orion and its passengers through the 65 00:02:41,110 --> 00:02:38,640 longest stretch between stepping stones 66 00:02:43,190 --> 00:02:41,120 design plans are still being researched 67 00:02:46,550 --> 00:02:43,200 but an onboard habitation module will 68 00:02:48,710 --> 00:02:46,560 help normalize the long journey to mars 69 00:02:50,790 --> 00:02:48,720 and finally the martian orbital 70 00:02:52,630 --> 00:02:50,800 observatory is the planned deep space 71 00:02:54,869 --> 00:02:52,640 workstation that will receive the deep 72 00:02:58,550 --> 00:02:54,879 space transport and serve as the primary 73 00:03:00,550 --> 00:02:58,560 living quarters for astronauts at mars 74 00:03:03,110 --> 00:03:00,560 taking the aries pathway to mars is 75 00:03:05,190 --> 00:03:03,120 similar to a baton race 76 00:03:07,509 --> 00:03:05,200 but the real challenge lies in surviving 77 00:03:08,869 --> 00:03:07,519 the journey researchers predict that a 78 00:03:11,509 --> 00:03:08,879 single mars mission can take 79 00:03:13,589 --> 00:03:11,519 approximately three years which poses a 80 00:03:16,710 --> 00:03:13,599 number of stressors for nasa astronaut 81 00:03:18,470 --> 00:03:16,720 crew they include health risks like 82 00:03:20,710 --> 00:03:18,480 exposure to cosmic radiation or 83 00:03:22,710 --> 00:03:20,720 prolonged weightlessness psychological 84 00:03:24,630 --> 00:03:22,720 effects from isolation especially in 85 00:03:26,550 --> 00:03:24,640 being disconnected from real-life earth 86 00:03:28,229 --> 00:03:26,560 events and interactions 87 00:03:29,990 --> 00:03:28,239 social effects of living with a small 88 00:03:32,630 --> 00:03:30,000 group of people in cramped conditions 89 00:03:34,949 --> 00:03:32,640 for a long period of time and technical 90 00:03:37,110 --> 00:03:34,959 issues like spacecraft repair or medical 91 00:03:38,949 --> 00:03:37,120 emergencies 92 00:03:41,270 --> 00:03:38,959 nasa plans to solve these issues by 93 00:03:43,270 --> 00:03:41,280 using sls rockets to stock food and 94 00:03:46,949 --> 00:03:43,280 supplies at each stepping stone of the 95 00:03:48,710 --> 00:03:46,959 aries pathway before orion arrives 96 00:03:51,110 --> 00:03:48,720 both the deep space transport and 97 00:03:53,110 --> 00:03:51,120 martian orbital observatory will provide 98 00:03:54,470 --> 00:03:53,120 ample space to facilitate spacecraft 99 00:03:56,710 --> 00:03:54,480 maintenance 100 00:03:58,229 --> 00:03:56,720 mission communications 101 00:04:00,710 --> 00:03:58,239 exercise 102 00:04:03,589 --> 00:04:00,720 and room for personal recreation 103 00:04:05,270 --> 00:04:03,599 to stay down to earth mars explorers may 104 00:04:08,949 --> 00:04:05,280 even do things to 105 00:04:11,509 --> 00:04:08,959 normalize their time away from home 106 00:04:12,710 --> 00:04:11,519 but once on mars there is so much to 107 00:04:15,110 --> 00:04:12,720 explore 108 00:04:16,870 --> 00:04:15,120 nasa astronaut crew can use a variety of 109 00:04:19,110 --> 00:04:16,880 exploration vehicles on the martian 110 00:04:21,349 --> 00:04:19,120 orbital observatory to travel to an 111 00:04:23,670 --> 00:04:21,359 ideal mars landing site for their next 112 00:04:25,030 --> 00:04:23,680 research steps 113 00:04:26,150 --> 00:04:25,040 whether it's to investigate the 114 00:04:28,150 --> 00:04:26,160 environment 115 00:04:29,830 --> 00:04:28,160 to explore possibilities for building a 116 00:04:31,270 --> 00:04:29,840 society on mars 117 00:04:33,270 --> 00:04:31,280 or to search for signs of 118 00:04:37,350 --> 00:04:33,280 extraterrestrial life 119 00:04:39,830 --> 00:04:37,360 the opportunities on mars are endless 120 00:04:42,469 --> 00:04:39,840 our desire to explore the universe has 121 00:04:44,550 --> 00:04:42,479 always been built on a dream 122 00:04:46,790 --> 00:04:44,560 we've taken big steps before 123 00:04:48,629 --> 00:04:46,800 everything we have and enjoy today is 124 00:04:50,629 --> 00:04:48,639 the result of the thousands of steps 125 00:04:54,469 --> 00:04:50,639 humankind has taken over the years to 126 00:04:57,350 --> 00:04:54,479 discover the wonderful world around us 127 00:04:59,270 --> 00:04:57,360 so where do we go next next time you 128 00:05:02,070 --> 00:04:59,280 look up at the night sky consider where 129 00:05:07,330 --> 00:05:02,080 we've gone and where we're going and ask 130 00:05:17,980 --> 00:05:07,340 yourself how big can you dream
