1 00:00:07,749 --> 00:00:05,510 for more than 14 years now without a 2 00:00:10,070 --> 00:00:07,759 break of even a single day there have 3 00:00:12,549 --> 00:00:10,080 been people living and working in space 4 00:00:15,509 --> 00:00:12,559 to get humankind ready to go out into 5 00:00:17,349 --> 00:00:15,519 deep space to find out what's out there 6 00:00:20,390 --> 00:00:17,359 today the international space station's 7 00:00:22,870 --> 00:00:20,400 expedition 42 crew is doing its part by 8 00:00:24,790 --> 00:00:22,880 focusing on science research developing 9 00:00:27,109 --> 00:00:24,800 new technologies and keeping their 10 00:00:29,029 --> 00:00:27,119 spaceship in top operating condition to 11 00:00:30,390 --> 00:00:29,039 support all the work 12 00:00:32,709 --> 00:00:30,400 anything you have in your home your air 13 00:00:34,310 --> 00:00:32,719 conditioning system whatever it might be 14 00:00:35,510 --> 00:00:34,320 over time something wears out a part 15 00:00:37,350 --> 00:00:35,520 wears out and you got to call the guy to 16 00:00:39,350 --> 00:00:37,360 come fix it well we don't we don't call 17 00:00:42,069 --> 00:00:39,360 anybody we have to fix it ourselves that 18 00:00:44,389 --> 00:00:42,079 is a major part of living in space just 19 00:00:46,229 --> 00:00:44,399 like living here on earth 20 00:00:48,389 --> 00:00:46,239 station maintenance doesn't just mean 21 00:00:50,549 --> 00:00:48,399 fixing things inside 22 00:00:53,029 --> 00:00:50,559 sometimes it means a trip out the 23 00:00:55,350 --> 00:00:53,039 airlock wilmore and flight engineer 24 00:00:57,750 --> 00:00:55,360 terry verts are planning spacewalks 25 00:00:59,830 --> 00:00:57,760 focused on new docking adapters for 26 00:01:01,430 --> 00:00:59,840 future crew vehicles when we have 27 00:01:03,590 --> 00:01:01,440 american spacecraft coming to the 28 00:01:05,830 --> 00:01:03,600 station again hopefully in a few years 29 00:01:08,469 --> 00:01:05,840 these spaceships will need to dock and 30 00:01:09,670 --> 00:01:08,479 the docking areas need to be launched 31 00:01:11,190 --> 00:01:09,680 and installed 32 00:01:12,870 --> 00:01:11,200 the only problem is 33 00:01:15,590 --> 00:01:12,880 they just don't snap on and work they 34 00:01:17,270 --> 00:01:15,600 have to have power so you the power 35 00:01:19,109 --> 00:01:17,280 cables and systems that were designed 36 00:01:21,429 --> 00:01:19,119 for the shuttle system are not the same 37 00:01:22,950 --> 00:01:21,439 for these docking adapters so eventually 38 00:01:25,429 --> 00:01:22,960 these docking adapters go on but when 39 00:01:27,190 --> 00:01:25,439 they get there they gotta have power so 40 00:01:29,270 --> 00:01:27,200 terry verts and i right now are 41 00:01:30,550 --> 00:01:29,280 scheduled to run some cables we're the 42 00:01:32,230 --> 00:01:30,560 cable guys 43 00:01:34,630 --> 00:01:32,240 it's the most cables and the longest 44 00:01:36,469 --> 00:01:34,640 cables ever in a in a 10 year long 45 00:01:38,710 --> 00:01:36,479 assembly sequence with lots of cables 46 00:01:40,710 --> 00:01:38,720 this is the most that's ever been done 47 00:01:43,190 --> 00:01:40,720 keeping the station running supports all 48 00:01:46,069 --> 00:01:43,200 the science including experiments on the 49 00:01:48,149 --> 00:01:46,079 exterior of the station that point up to 50 00:01:51,190 --> 00:01:48,159 gather cosmic particles in the search 51 00:01:53,670 --> 00:01:51,200 for dark matter or look down to observe 52 00:01:55,670 --> 00:01:53,680 earth from a unique vantage point 53 00:01:57,990 --> 00:01:55,680 inside the station the human crew 54 00:01:59,590 --> 00:01:58,000 members facilitate a wide range of 55 00:02:01,510 --> 00:01:59,600 investigations 56 00:02:03,429 --> 00:02:01,520 we're not scientists necessarily on 57 00:02:05,429 --> 00:02:03,439 board we're like lab technicians we have 58 00:02:07,670 --> 00:02:05,439 to lend our hands to the to the 59 00:02:09,669 --> 00:02:07,680 scientists to physically do a few 60 00:02:12,150 --> 00:02:09,679 tasks that of course cannot be done from 61 00:02:14,150 --> 00:02:12,160 the ground it's one of the privileges of 62 00:02:16,229 --> 00:02:14,160 being an instrument is that you really 63 00:02:18,710 --> 00:02:16,239 work with i'd say hundreds maybe it's 64 00:02:21,110 --> 00:02:18,720 more of people who are really top 65 00:02:22,550 --> 00:02:21,120 experts in their fields 66 00:02:23,350 --> 00:02:22,560 the thing about science is you never 67 00:02:25,910 --> 00:02:23,360 know 68 00:02:27,750 --> 00:02:25,920 what you're going to get and the really 69 00:02:29,589 --> 00:02:27,760 easy discoveries were all made you know 70 00:02:31,910 --> 00:02:29,599 500 years ago the apple hits the ground 71 00:02:33,509 --> 00:02:31,920 hey there's gravity you know that people 72 00:02:34,869 --> 00:02:33,519 all the low-hanging fruit so to speak 73 00:02:36,630 --> 00:02:34,879 have already been picked and so the 74 00:02:38,550 --> 00:02:36,640 science that we're doing now 75 00:02:40,229 --> 00:02:38,560 is really 76 00:02:42,949 --> 00:02:40,239 a link in a chain 77 00:02:44,869 --> 00:02:42,959 that might be a thousand links long 78 00:02:47,750 --> 00:02:44,879 this crew will work on research ranging 79 00:02:50,070 --> 00:02:47,760 from 3d printing to combustion and fire 80 00:02:51,430 --> 00:02:50,080 prevention to plant growth and physics 81 00:02:53,990 --> 00:02:51,440 and much more 82 00:02:56,790 --> 00:02:54,000 on top of all that each crew member is a 83 00:02:59,589 --> 00:02:56,800 test subject for ongoing research into 84 00:03:01,350 --> 00:02:59,599 how human bodies are affected by being 85 00:03:03,990 --> 00:03:01,360 in the space environment for a long 86 00:03:06,390 --> 00:03:04,000 period of time as will be the case for 87 00:03:07,750 --> 00:03:06,400 the human crew members on future deep 88 00:03:09,910 --> 00:03:07,760 space missions 89 00:03:12,390 --> 00:03:09,920 the trick is figuring out how a body 90 00:03:14,630 --> 00:03:12,400 that weakens in the absence of gravity 91 00:03:16,830 --> 00:03:14,640 can be strong enough to work when it 92 00:03:20,470 --> 00:03:16,840 encounters gravity again 93 00:03:23,110 --> 00:03:20,480 uh because getting used to zero gravity 94 00:03:26,229 --> 00:03:23,120 was so easy for me and then you start 95 00:03:27,910 --> 00:03:26,239 feeling yourself so comfortable 96 00:03:30,789 --> 00:03:27,920 within a couple of weeks 97 00:03:33,670 --> 00:03:30,799 after my six-month mission when i came 98 00:03:36,869 --> 00:03:33,680 back to earth i realized that earth is 99 00:03:38,949 --> 00:03:36,879 not really happy to see me and my body 100 00:03:40,390 --> 00:03:38,959 is not happy to be back to 101 00:03:42,710 --> 00:03:40,400 earth gravity 102 00:03:44,869 --> 00:03:42,720 so everything about these people is part 103 00:03:47,750 --> 00:03:44,879 of the research 104 00:03:48,789 --> 00:03:47,760 we do experiments to see how blood 105 00:03:51,830 --> 00:03:48,799 changes 106 00:03:54,789 --> 00:03:51,840 how 107 00:03:59,270 --> 00:03:54,799 bone mass changes and bone density 108 00:04:01,350 --> 00:03:59,280 changes this is a huge scope of research 109 00:04:03,990 --> 00:04:01,360 supporting the work of the crew requires 110 00:04:06,309 --> 00:04:04,000 periodic deliveries of new supplies and 111 00:04:09,110 --> 00:04:06,319 this station gets them via cargo ships 112 00:04:10,710 --> 00:04:09,120 provided by station partners and private 113 00:04:13,830 --> 00:04:10,720 contractors 114 00:04:17,430 --> 00:04:13,840 all these vehicles are necessary to 115 00:04:19,990 --> 00:04:17,440 deliver hardware to the station water 116 00:04:21,509 --> 00:04:20,000 food supplies oxygen everything that 117 00:04:23,430 --> 00:04:21,519 supports the operation of the 118 00:04:25,510 --> 00:04:23,440 international space station 119 00:04:27,990 --> 00:04:25,520 in february this crew will oversee the 120 00:04:30,870 --> 00:04:28,000 departure of the european space agency's 121 00:04:33,189 --> 00:04:30,880 final automated transfer vehicle its 122 00:04:35,670 --> 00:04:33,199 ordinary destructive plunge into the 123 00:04:38,070 --> 00:04:35,680 atmosphere will be adjusted to gather 124 00:04:40,390 --> 00:04:38,080 data for the future fiery finale of an 125 00:04:42,469 --> 00:04:40,400 even larger vehicle the international 126 00:04:44,629 --> 00:04:42,479 space station itself 127 00:04:46,629 --> 00:04:44,639 so to make absolutely and fully sure 128 00:04:49,830 --> 00:04:46,639 that we understand this we are going to 129 00:04:53,030 --> 00:04:49,840 guide htv through a shallow reentry that 130 00:04:54,629 --> 00:04:53,040 should mimic what the re-entry of the 131 00:04:57,830 --> 00:04:54,639 space station will be at some point in 132 00:04:59,670 --> 00:04:57,840 the future and we will have like i think 133 00:05:04,390 --> 00:04:59,680 i think 100 or more 134 00:05:08,390 --> 00:05:06,390 when wilmore and his soyuz crewmates 135 00:05:10,790 --> 00:05:08,400 come home in march verts becomes 136 00:05:12,629 --> 00:05:10,800 commander for expedition 43 137 00:05:14,390 --> 00:05:12,639 and when he opens the door two weeks 138 00:05:17,029 --> 00:05:14,400 later for soyuz commander gennady 139 00:05:19,749 --> 00:05:17,039 padalka he'll usher in the international 140 00:05:21,590 --> 00:05:19,759 space station's first year-long mission 141 00:05:24,469 --> 00:05:21,600 which will be completed by padalka's 142 00:05:26,310 --> 00:05:24,479 crewmates nasa astronaut scott kelly and 143 00:05:28,390 --> 00:05:26,320 cosmonaut mikhail kornienko of the 144 00:05:31,749 --> 00:05:28,400 russian federal space agency who will 145 00:05:33,590 --> 00:05:31,759 remain on board through expedition 46. 146 00:05:36,230 --> 00:05:33,600 the mission for verts shkaplerov and 147 00:05:38,070 --> 00:05:36,240 christopher reddy runs into may adding 148 00:05:40,230 --> 00:05:38,080 to the lessons learned in low earth 149 00:05:43,670 --> 00:05:40,240 orbit that will be applied to build 150 00:05:45,510 --> 00:05:43,680 humankind's future in space 151 00:05:48,070 --> 00:05:45,520 if we want to 152 00:05:49,670 --> 00:05:48,080 conduct further exploration in a robust 153 00:05:51,670 --> 00:05:49,680 manner 154 00:05:52,390 --> 00:05:51,680 those are all lessons that we needed to 155 00:05:54,550 --> 00:05:52,400 learn 156 00:05:55,909 --> 00:05:54,560 and i think it will be invaluable for
