1 00:00:08,390 --> 00:00:07,190 we are a facility which is going to go 2 00:00:10,790 --> 00:00:08,400 inside of the international space 3 00:00:12,709 --> 00:00:10,800 station as an express rack payload and 4 00:00:14,709 --> 00:00:12,719 it is a fundamental physics facility 5 00:00:15,829 --> 00:00:14,719 which will allow scientists to perform 6 00:00:17,750 --> 00:00:15,839 research on something called 7 00:00:19,189 --> 00:00:17,760 bose-einstein condensates which is 8 00:00:20,310 --> 00:00:19,199 another state of matter where we get 9 00:00:23,029 --> 00:00:20,320 down to temperatures which are 10 00:00:25,189 --> 00:00:23,039 incredibly cold meaning 100 times 10 to 11 00:00:26,710 --> 00:00:25,199 the minus 12 kelvin which is on the 12 00:00:28,710 --> 00:00:26,720 order of a million times colder than 13 00:00:30,150 --> 00:00:28,720 even the temperature of space how in the 14 00:00:31,990 --> 00:00:30,160 world did we come up with this idea that 15 00:00:34,229 --> 00:00:32,000 we needed this 16 00:00:35,670 --> 00:00:34,239 so it is a science experiment and 17 00:00:37,510 --> 00:00:35,680 condensed matter physics is one of the 18 00:00:40,069 --> 00:00:37,520 most important areas of physics under 19 00:00:41,990 --> 00:00:40,079 research today and we're able to create 20 00:00:43,750 --> 00:00:42,000 these bose einstein condensates using a 21 00:00:45,110 --> 00:00:43,760 technique called laser cooling and when 22 00:00:46,709 --> 00:00:45,120 you use this technique called laser 23 00:00:47,830 --> 00:00:46,719 cooling in a microgravity environment 24 00:00:49,590 --> 00:00:47,840 which you get on the space station you 25 00:00:51,110 --> 00:00:49,600 can get to much colder temperatures and 26 00:00:52,310 --> 00:00:51,120 so basically we want to see what happens 27 00:00:53,670 --> 00:00:52,320 when we get matter down to these 28 00:00:55,510 --> 00:00:53,680 temperatures because they actually start 29 00:00:57,110 --> 00:00:55,520 instead of behaving like particles or 30 00:00:59,430 --> 00:00:57,120 billiard balls matter actually behaves 31 00:01:01,430 --> 00:00:59,440 as waves what does this facility look 32 00:01:03,029 --> 00:01:01,440 like you said it goes to an express rack 33 00:01:06,070 --> 00:01:03,039 yes it goes inside of an express rack on 34 00:01:08,469 --> 00:01:06,080 the space station and it's about um i 35 00:01:10,390 --> 00:01:08,479 would say about the size of two filing 36 00:01:12,630 --> 00:01:10,400 cabinets in width and about a filing 37 00:01:14,870 --> 00:01:12,640 cabinet in depth and it's a box and 38 00:01:17,190 --> 00:01:14,880 inside of the box we have all of our 39 00:01:18,469 --> 00:01:17,200 electronics and our lasers and our 40 00:01:19,830 --> 00:01:18,479 physics package which is actually the 41 00:01:21,830 --> 00:01:19,840 heart of the instrument so from the 42 00:01:23,350 --> 00:01:21,840 outside from what the astronauts can see 43 00:01:24,950 --> 00:01:23,360 it looks like a box from the inside it's 44 00:01:27,510 --> 00:01:24,960 a very sophisticated laser 45 00:01:29,749 --> 00:01:27,520 optomechanical system 46 00:01:32,149 --> 00:01:29,759 laser optics has become quite a 47 00:01:34,870 --> 00:01:32,159 quite a hot topic a hotbed on space 48 00:01:36,069 --> 00:01:34,880 station right i think so yeah and so in 49 00:01:38,390 --> 00:01:36,079 particular this will be the first 50 00:01:39,990 --> 00:01:38,400 demonstration of laser cooling which has 51 00:01:42,630 --> 00:01:40,000 a whole bunch of technology applications 52 00:01:43,910 --> 00:01:42,640 as well so not hot but cold yes so it's 53 00:01:45,429 --> 00:01:43,920 a little bit counterintuitive where you 54 00:01:47,109 --> 00:01:45,439 can actually use lasers to cool 55 00:01:49,030 --> 00:01:47,119 something down and what you're actually 56 00:01:50,789 --> 00:01:49,040 doing is you're using the momentum of 57 00:01:53,190 --> 00:01:50,799 photons to push on atoms which are 58 00:01:54,950 --> 00:01:53,200 coming towards it we are pretty much 59 00:01:56,630 --> 00:01:54,960 autonomous in the sense that we're 60 00:01:59,190 --> 00:01:56,640 controlled from the ground the crew will 61 00:02:00,389 --> 00:01:59,200 have to install the experiment and over 62 00:02:02,069 --> 00:02:00,399 time there may be parts of the 63 00:02:03,429 --> 00:02:02,079 experiment that need to be repaired or 64 00:02:04,950 --> 00:02:03,439 upgraded and the crew will do that as 65 00:02:06,789 --> 00:02:04,960 well so this experiment is designed to 66 00:02:08,869 --> 00:02:06,799 be modular but in terms of nominal 67 00:02:10,710 --> 00:02:08,879 operations it's all operated remotely 68 00:02:12,309 --> 00:02:10,720 from jpl and we specifically operate 69 00:02:14,710 --> 00:02:12,319 during the crew sleep period because our 70 00:02:17,510 --> 00:02:14,720 instrument is sensitive to vibrations 71 00:02:19,110 --> 00:02:17,520 isis will become the coldest spot in the 72 00:02:21,030 --> 00:02:19,120 universe 73 00:02:23,030 --> 00:02:21,040 through this experiment 74 00:02:24,309 --> 00:02:23,040 we will also 75 00:02:27,110 --> 00:02:24,319 observe 76 00:02:29,350 --> 00:02:27,120 over an extended period of time and we 77 00:02:30,710 --> 00:02:29,360 really don't know what to expect we have 78 00:02:32,630 --> 00:02:30,720 some 79 00:02:34,470 --> 00:02:32,640 assumptions so 80 00:02:37,509 --> 00:02:34,480 what really makes it interesting about 81 00:02:39,750 --> 00:02:37,519 cal is this element of the unknown of 82 00:02:41,830 --> 00:02:39,760 the discovery of the 83 00:02:44,070 --> 00:02:41,840 future 84 00:02:46,550 --> 00:02:44,080 exploration of 85 00:02:47,910 --> 00:02:46,560 a region which we don't know 86 00:02:49,509 --> 00:02:47,920 what we 87 00:02:52,869 --> 00:02:49,519 would expect and it's interesting to see 88 00:02:54,390 --> 00:02:52,879 it started in 1920s by with einstein and 89 00:02:57,750 --> 00:02:54,400 cal 90 00:02:58,869 --> 00:02:57,760 only through iss will will enable us to 91 00:03:01,910 --> 00:02:58,879 uncover 92 00:03:05,509 --> 00:03:01,920 this unknown so we were all excited 93 00:03:06,869 --> 00:03:05,519 about what cal and iss combine will 94 00:03:08,630 --> 00:03:06,879 provide us 95 00:03:11,910 --> 00:03:08,640 so the cold atom lab is just the first 96 00:03:13,589 --> 00:03:11,920 step that's correct because we feel 97 00:03:15,190 --> 00:03:13,599 what 98 00:03:20,470 --> 00:03:15,200 laser has 99 00:03:25,670 --> 00:03:23,430 all aspects of physics and daily lives 100 00:03:26,550 --> 00:03:25,680 what laser did to physics 101 00:03:33,350 --> 00:03:26,560 and 102 00:03:36,149 --> 00:03:33,360 believe that 103 00:03:39,190 --> 00:03:36,159 by cooling atoms to this very 104 00:03:41,670 --> 00:03:39,200 near absolute uh zero temperature 105 00:03:46,229 --> 00:03:41,680 we'll also open up an array of 106 00:03:47,430 --> 00:03:46,239 technologies from super uh computers to 107 00:03:49,990 --> 00:03:47,440 you know
