1 00:00:05,349 --> 00:00:03,110 exactly what cindy does the instrument 2 00:00:08,310 --> 00:00:05,359 only the instrument you know catches 3 00:00:10,310 --> 00:00:08,320 neutral particles and ionized particles 4 00:00:11,990 --> 00:00:10,320 one of the big attractions at every agu 5 00:00:13,910 --> 00:00:12,000 meeting is right here in the exhibit 6 00:00:16,630 --> 00:00:13,920 hall this is where all this stuff of 7 00:00:19,670 --> 00:00:16,640 science is on display 8 00:00:22,470 --> 00:00:19,680 scientific instruments 9 00:00:28,950 --> 00:00:26,070 exploration equipment of all kinds 10 00:00:34,470 --> 00:00:28,960 comic books and apparently comic book 11 00:00:39,350 --> 00:00:36,790 i'm cindy i'm an android space girl 12 00:00:42,150 --> 00:00:39,360 who's also a dog catcher in my spare 13 00:00:43,190 --> 00:00:42,160 time i'm also a nasa mascot for the 14 00:00:45,750 --> 00:00:43,200 cindy 15 00:00:47,670 --> 00:00:45,760 coupled ion neutral dynamics 16 00:00:50,630 --> 00:00:47,680 investigation and as a mission of 17 00:00:53,189 --> 00:00:50,640 opportunity so space dogs are fantastic 18 00:00:54,470 --> 00:00:53,199 i have two called tech and tech 19 00:00:56,950 --> 00:00:54,480 and 20 00:00:58,950 --> 00:00:56,960 space dogs are just like normal dogs 21 00:01:00,869 --> 00:00:58,960 except for they can lose their tails 22 00:01:02,549 --> 00:01:00,879 when they have their tails they're calm 23 00:01:04,950 --> 00:01:02,559 in their lap dogs and they're very 24 00:01:07,109 --> 00:01:04,960 comfortable to have around as pets 25 00:01:09,190 --> 00:01:07,119 but when energy biscuits come from the 26 00:01:11,429 --> 00:01:09,200 sun and the dogs eat them their tails 27 00:01:13,350 --> 00:01:11,439 pop off and they start chasing them 28 00:01:14,950 --> 00:01:13,360 around they're very very jumpy and 29 00:01:17,429 --> 00:01:14,960 energetic 30 00:01:19,670 --> 00:01:17,439 now my job as a dog catcher is to catch 31 00:01:22,070 --> 00:01:19,680 and release these dogs and i also study 32 00:01:24,310 --> 00:01:22,080 their migration patterns and what 33 00:01:25,510 --> 00:01:24,320 heights they live at in mice region of 34 00:01:27,190 --> 00:01:25,520 space 35 00:01:28,149 --> 00:01:27,200 their temperatures and how they move 36 00:01:29,749 --> 00:01:28,159 around 37 00:01:32,310 --> 00:01:29,759 there are a lot of people on earth that 38 00:01:34,870 --> 00:01:32,320 use my space dog data to investigate 39 00:01:36,710 --> 00:01:34,880 what's going on up in my levels of space 40 00:01:38,710 --> 00:01:36,720 there's a group at university in texas 41 00:01:40,469 --> 00:01:38,720 of dallas that is doing this 42 00:01:42,950 --> 00:01:40,479 one of the talks will be presented here 43 00:01:52,950 --> 00:01:42,960 at agu by a grad student named angeline 44 00:01:58,550 --> 00:01:56,149 in the out rifts to provide constraints 45 00:02:01,749 --> 00:01:58,560 on the lower thermostat 46 00:02:04,069 --> 00:02:01,759 so the talk i gave used the cindy data 47 00:02:05,990 --> 00:02:04,079 the ion velocities 48 00:02:09,430 --> 00:02:06,000 and compared them to the results from a 49 00:02:12,710 --> 00:02:09,440 model in order to provide boundaries 50 00:02:14,229 --> 00:02:12,720 on the magnitude of winds lower down in 51 00:02:15,990 --> 00:02:14,239 the atmosphere 52 00:02:17,670 --> 00:02:16,000 these winds are hard to measure and we 53 00:02:20,390 --> 00:02:17,680 don't currently have any satellites 54 00:02:22,869 --> 00:02:20,400 measuring them at that level so cindy 55 00:02:27,589 --> 00:02:22,879 studies the ionosphere which is the 56 00:02:34,229 --> 00:02:30,869 it's on board a satellite that's at the 57 00:02:36,390 --> 00:02:34,239 lowest 400 kilometers above the earth 58 00:02:39,430 --> 00:02:36,400 the part of cindy that i use measures 59 00:02:42,390 --> 00:02:39,440 the movement the temperature and the 60 00:02:43,750 --> 00:02:42,400 type and amount of the ions that it runs 61 00:02:46,229 --> 00:02:43,760 across 62 00:02:48,790 --> 00:02:46,239 so most of the atmosphere 63 00:02:51,270 --> 00:02:48,800 is neutral it's breathable it's made up 64 00:02:53,270 --> 00:02:51,280 of molecules and atoms 65 00:02:55,190 --> 00:02:53,280 and it gets thinner the further you get 66 00:02:57,990 --> 00:02:55,200 away from the earth 67 00:02:58,869 --> 00:02:58,000 by the time you get up to the level 68 00:03:01,110 --> 00:02:58,879 where 69 00:03:03,350 --> 00:03:01,120 the satellite that we're using xenops is 70 00:03:05,430 --> 00:03:03,360 at you have less than one percent of the 71 00:03:07,430 --> 00:03:05,440 atmosphere left 72 00:03:09,670 --> 00:03:07,440 when it's this thin 73 00:03:10,949 --> 00:03:09,680 it's very easy for radiation that comes 74 00:03:13,509 --> 00:03:10,959 from the sun 75 00:03:17,270 --> 00:03:13,519 to excite the particles and throw off an 76 00:03:19,110 --> 00:03:17,280 electron and cause an ion to be formed 77 00:03:20,869 --> 00:03:19,120 and the formation of the ionosphere is 78 00:03:23,750 --> 00:03:20,879 it protects us from most of the sun's 79 00:03:27,670 --> 00:03:23,760 radiation it absorbs a lot of the cosmic 80 00:03:30,550 --> 00:03:27,680 rays the x-rays and most of the 81 00:03:34,390 --> 00:03:30,560 uv radiation that comes out what made 82 00:03:36,470 --> 00:03:34,400 you decide to become a scientist 83 00:03:37,910 --> 00:03:36,480 well my first trip to the planetarium 84 00:03:40,550 --> 00:03:37,920 really 85 00:03:42,229 --> 00:03:40,560 i loved the stars and 86 00:03:48,869 --> 00:03:42,239 the 87 00:03:49,750 --> 00:03:48,879 so i decided 88 00:03:51,190 --> 00:03:49,760 that 89 00:03:53,270 --> 00:03:51,200 it was the most worthwhile and 90 00:03:56,149 --> 00:03:53,280 interesting thing to study 91 00:04:00,550 --> 00:03:56,159 i'd always been good at math and 92 00:04:03,030 --> 00:04:00,560 once i realized that i loved physics 93 00:04:05,270 --> 00:04:03,040 it was a no-brainer 94 00:04:06,949 --> 00:04:05,280 to find out more when you don't have a 95 00:04:08,390 --> 00:04:06,959 physics background can be a little bit 96 00:04:10,710 --> 00:04:08,400 difficult 97 00:04:13,350 --> 00:04:10,720 but one way i've used to explain to my 98 00:04:15,990 --> 00:04:13,360 friends and family is the comic books 99 00:04:18,229 --> 00:04:16,000 the cindy comic books cindy and space 100 00:04:21,430 --> 00:04:18,239 and cindy in the electric atmosphere 101 00:04:25,270 --> 00:04:21,440 they do a really good job of explaining 102 00:04:28,390 --> 00:04:25,280 in interesting terms and 103 00:04:31,749 --> 00:04:28,400 basic but relevant terms that do explain 104 00:04:32,950 --> 00:04:31,759 pretty much everything about what i do 105 00:04:34,950 --> 00:04:32,960 and about
