1 00:00:04,710 --> 00:00:02,550 well welcome to a mission control in 2 00:00:07,030 --> 00:00:04,720 houston my name is pat ryan i'm the 3 00:00:09,270 --> 00:00:07,040 public affairs officer on the orbit two 4 00:00:11,669 --> 00:00:09,280 shift here in mission control today and 5 00:00:13,110 --> 00:00:11,679 we've just finished up our live update 6 00:00:15,749 --> 00:00:13,120 on the activities on board the 7 00:00:17,670 --> 00:00:15,759 international space station and uh happy 8 00:00:19,590 --> 00:00:17,680 to join you and get to tell you more 9 00:00:21,590 --> 00:00:19,600 about nasa and about the space station 10 00:00:23,109 --> 00:00:21,600 what's going on i've invited along 11 00:00:26,150 --> 00:00:23,119 another one of our flight controllers 12 00:00:27,269 --> 00:00:26,160 who works here uh ken niece is a cronus 13 00:00:29,269 --> 00:00:27,279 specialist 14 00:00:31,189 --> 00:00:29,279 and we're going to find out what that is 15 00:00:33,350 --> 00:00:31,199 after we first find out about you what 16 00:00:36,069 --> 00:00:33,360 is it your professional background how 17 00:00:37,750 --> 00:00:36,079 did you end up at nasa okay um well i 18 00:00:39,990 --> 00:00:37,760 grew up in the philadelphia area 19 00:00:40,950 --> 00:00:40,000 philadelphia pennsylvania suburbs i was 20 00:00:43,830 --> 00:00:40,960 always 21 00:00:46,389 --> 00:00:43,840 proficient at taking things apart to my 22 00:00:49,270 --> 00:00:46,399 parents dismay they've labeled that 23 00:00:50,790 --> 00:00:49,280 breaking things but i always wanted to 24 00:00:52,790 --> 00:00:50,800 see how things worked 25 00:00:55,830 --> 00:00:52,800 and along the way i 26 00:00:58,310 --> 00:00:55,840 had was very good at math and sciences 27 00:01:00,389 --> 00:00:58,320 so i pursued the field of engineering 28 00:01:01,830 --> 00:01:00,399 when i went into college i went to penn 29 00:01:03,510 --> 00:01:01,840 state university 30 00:01:05,670 --> 00:01:03,520 got my graduate 31 00:01:07,350 --> 00:01:05,680 undergraduate and my graduate degree at 32 00:01:08,870 --> 00:01:07,360 penn state and 33 00:01:11,190 --> 00:01:08,880 at that point 34 00:01:13,350 --> 00:01:11,200 i got recruited by nasa at one of the 35 00:01:14,230 --> 00:01:13,360 college fairs career fairs 36 00:01:17,190 --> 00:01:14,240 and 37 00:01:17,990 --> 00:01:17,200 i've been working here ever since 38 00:01:19,590 --> 00:01:18,000 let's 39 00:01:21,190 --> 00:01:19,600 find out as i said we're going to find 40 00:01:22,710 --> 00:01:21,200 out what a cronus does because i imagine 41 00:01:24,149 --> 00:01:22,720 that that's one of the first questions 42 00:01:25,510 --> 00:01:24,159 that we're going to hear we're ready to 43 00:01:32,870 --> 00:01:25,520 hear what the kids in little rock have 44 00:01:39,270 --> 00:01:35,350 good morning my name is daniel ray and 45 00:01:43,510 --> 00:01:41,830 and i have a question for you 46 00:01:45,670 --> 00:01:43,520 there 47 00:01:49,270 --> 00:01:45,680 could you name one or two conditions 48 00:01:52,389 --> 00:01:49,280 that could negatively affect operations 49 00:01:54,710 --> 00:01:52,399 for the flight control team 50 00:01:56,230 --> 00:01:54,720 that is a really good question uh there 51 00:01:58,389 --> 00:01:56,240 are a couple things 52 00:01:59,270 --> 00:01:58,399 that could negatively affect us down 53 00:02:00,789 --> 00:01:59,280 here 54 00:02:03,030 --> 00:02:00,799 the first is 55 00:02:06,069 --> 00:02:03,040 loss of communications 56 00:02:08,070 --> 00:02:06,079 one of our main ways to 57 00:02:11,190 --> 00:02:08,080 figure out how things are going on on 58 00:02:13,990 --> 00:02:11,200 the space station is via the telemetry 59 00:02:17,030 --> 00:02:14,000 and data rece receive on the ground and 60 00:02:19,830 --> 00:02:17,040 by actually talking to the crew if 61 00:02:22,710 --> 00:02:19,840 we don't have those links 62 00:02:24,150 --> 00:02:22,720 then we don't have a way to 63 00:02:26,070 --> 00:02:24,160 talk to the crew to figure out what's 64 00:02:28,150 --> 00:02:26,080 going on or to 65 00:02:31,190 --> 00:02:28,160 interact intervene 66 00:02:33,350 --> 00:02:31,200 from the ground fix anything so it's 67 00:02:34,830 --> 00:02:33,360 really important for us to try to 68 00:02:37,589 --> 00:02:34,840 utilize our 69 00:02:38,309 --> 00:02:37,599 communication time frames as best as we 70 00:02:40,470 --> 00:02:38,319 can 71 00:02:42,630 --> 00:02:40,480 another thing that could negatively 72 00:02:46,710 --> 00:02:42,640 affect affect us is 73 00:02:48,309 --> 00:02:46,720 a malfunction if something does go wrong 74 00:02:51,509 --> 00:02:48,319 everything that's scheduled for the day 75 00:02:53,830 --> 00:02:51,519 depending on how big the malfunction is 76 00:02:55,430 --> 00:02:53,840 the whole day could be wiped out so it 77 00:02:58,149 --> 00:02:55,440 really depends on what the malfunction 78 00:02:59,830 --> 00:02:58,159 is but 79 00:03:01,670 --> 00:02:59,840 those are some of the big things that 80 00:03:04,550 --> 00:03:01,680 can really 81 00:03:07,110 --> 00:03:04,560 affect the ground controllers us here on 82 00:03:08,949 --> 00:03:07,120 the ground the flight controller team 83 00:03:11,509 --> 00:03:08,959 and particularly for for you for a 84 00:03:14,149 --> 00:03:11,519 cronus officer explain what it is what 85 00:03:16,710 --> 00:03:14,159 systems you guys are charged with 86 00:03:19,750 --> 00:03:16,720 maintaining as acronis we are in charge 87 00:03:21,430 --> 00:03:19,760 of those communication pathways so 88 00:03:24,309 --> 00:03:21,440 the voice 89 00:03:26,710 --> 00:03:24,319 that commands the data we get from the 90 00:03:28,710 --> 00:03:26,720 space station 91 00:03:31,350 --> 00:03:28,720 the video that we get down from the 92 00:03:34,229 --> 00:03:31,360 space station all the status health and 93 00:03:36,550 --> 00:03:34,239 status of our systems of our 94 00:03:39,190 --> 00:03:36,560 payload data our science data comes down 95 00:03:41,830 --> 00:03:39,200 through the systems that i manage 96 00:03:44,869 --> 00:03:41,840 so that's what we're in control of 97 00:03:51,509 --> 00:03:44,879 and and it's a really fun job 98 00:03:55,830 --> 00:03:53,750 my name is kyle holmes and i'm in the 99 00:03:59,589 --> 00:03:55,840 eighth grade 100 00:04:01,670 --> 00:03:59,599 about one with the flight controller 101 00:04:02,710 --> 00:04:01,680 command history logs 102 00:04:05,830 --> 00:04:02,720 daily 103 00:04:07,750 --> 00:04:05,840 weekly monthly or win 104 00:04:10,070 --> 00:04:07,760 that's another very specific yeah that's 105 00:04:12,149 --> 00:04:10,080 a very good question um 106 00:04:14,869 --> 00:04:12,159 part of my discipline were responsible 107 00:04:17,430 --> 00:04:14,879 for the computers and downlinking those 108 00:04:20,629 --> 00:04:17,440 logs like you talked about 109 00:04:22,790 --> 00:04:20,639 we don't we downlink uh detailed data 110 00:04:25,189 --> 00:04:22,800 from the main computer about once a week 111 00:04:27,270 --> 00:04:25,199 on a sunday afternoon 112 00:04:29,110 --> 00:04:27,280 we get more detailed data from the 113 00:04:30,870 --> 00:04:29,120 crew's personal computers personal 114 00:04:33,030 --> 00:04:30,880 computers they use to command and 115 00:04:36,629 --> 00:04:33,040 receive data from the systems we 116 00:04:40,070 --> 00:04:36,639 downlink that about once every month 117 00:04:42,790 --> 00:04:40,080 behind me in the background we do get 118 00:04:44,310 --> 00:04:42,800 real-time command history data basically 119 00:04:48,390 --> 00:04:44,320 all the commands that we send from the 120 00:04:50,550 --> 00:04:48,400 ground we get a log of that and we we 121 00:04:52,950 --> 00:04:50,560 are constantly saving that so for 122 00:04:55,189 --> 00:04:52,960 historical purposes and to see what is 123 00:04:56,469 --> 00:04:55,199 what has happened 124 00:05:01,830 --> 00:04:56,479 good 125 00:05:06,469 --> 00:05:04,390 hi my name is jonathan jordan and i'm 126 00:05:08,230 --> 00:05:06,479 currently in the eighth grade 127 00:05:11,670 --> 00:05:08,240 i have two questions i would like to ask 128 00:05:14,390 --> 00:05:11,680 you the first one where exactly are the 129 00:05:17,110 --> 00:05:14,400 multiplexer computers located on the 130 00:05:18,870 --> 00:05:17,120 international spaceship or also known as 131 00:05:19,749 --> 00:05:18,880 iss 132 00:05:20,629 --> 00:05:19,759 okay 133 00:05:24,390 --> 00:05:20,639 um 134 00:05:26,310 --> 00:05:24,400 the the multiplexer demonstration 135 00:05:27,749 --> 00:05:26,320 sorry it's a hard word basically our 136 00:05:29,110 --> 00:05:27,759 main computers are located all 137 00:05:30,629 --> 00:05:29,120 throughout the space because there are 138 00:05:32,790 --> 00:05:30,639 very many of them there are there are 139 00:05:35,909 --> 00:05:32,800 over 40 of them um 140 00:05:38,230 --> 00:05:35,919 so we have three tiers of of 141 00:05:39,189 --> 00:05:38,240 these main computers 142 00:05:40,950 --> 00:05:39,199 and 143 00:05:42,790 --> 00:05:40,960 some of them located inside some are 144 00:05:44,790 --> 00:05:42,800 outside some are inside the lab module 145 00:05:46,870 --> 00:05:44,800 in various racks 146 00:05:49,110 --> 00:05:46,880 some are in end cones 147 00:05:51,189 --> 00:05:49,120 some in the like i said the lab node 2 148 00:05:52,469 --> 00:05:51,199 node 3 air lock 149 00:05:54,550 --> 00:05:52,479 the pmm 150 00:05:56,710 --> 00:05:54,560 and then there's a whole bunch outside 151 00:05:58,070 --> 00:05:56,720 on the external trusses so they're 152 00:06:00,390 --> 00:05:58,080 everywhere and they need to be 153 00:06:02,070 --> 00:06:00,400 everywhere to do all the jobs that 154 00:06:04,550 --> 00:06:02,080 they're responsible for and the 155 00:06:06,550 --> 00:06:04,560 multiplexer demultiplexer computers is 156 00:06:08,309 --> 00:06:06,560 there a way to characterize the 157 00:06:10,550 --> 00:06:08,319 the level where they are they're not 158 00:06:12,629 --> 00:06:10,560 just the standard laptops 159 00:06:14,550 --> 00:06:12,639 that the crew interact with all the time 160 00:06:17,670 --> 00:06:14,560 these are the computers that any that 161 00:06:20,230 --> 00:06:17,680 range from uh directly directing uh 162 00:06:22,550 --> 00:06:20,240 traffic from the sensors and effectors 163 00:06:25,029 --> 00:06:22,560 for the data we're trying to gather to 164 00:06:27,189 --> 00:06:25,039 passing it up and interfacing with other 165 00:06:28,230 --> 00:06:27,199 mod other modules or other international 166 00:06:30,070 --> 00:06:28,240 partners 167 00:06:31,270 --> 00:06:30,080 all the way up to our prime computer 168 00:06:33,189 --> 00:06:31,280 which is responsible for putting 169 00:06:35,189 --> 00:06:33,199 together all the data being the cruise 170 00:06:36,950 --> 00:06:35,199 interface and shipping that data where 171 00:06:39,830 --> 00:06:36,960 it needs to be such as the ground or the 172 00:06:41,990 --> 00:06:39,840 cruise laptops 173 00:06:44,390 --> 00:06:42,000 next one 174 00:06:47,110 --> 00:06:44,400 and my second question is how many 175 00:06:49,589 --> 00:06:47,120 channels does the q band communication 176 00:06:52,150 --> 00:06:49,599 systems have 177 00:06:54,790 --> 00:06:52,160 the kuben system uh right now we were 178 00:06:55,909 --> 00:06:54,800 able to get six downlink channels six 179 00:06:57,350 --> 00:06:55,919 downlink 180 00:07:00,230 --> 00:06:57,360 video 181 00:07:03,189 --> 00:07:00,240 either hd or standard definition in 182 00:07:05,670 --> 00:07:03,199 addition to uh ability to talk 183 00:07:07,909 --> 00:07:05,680 via ip phone internet protocol phone to 184 00:07:10,870 --> 00:07:07,919 the crew we can even send email through 185 00:07:13,670 --> 00:07:10,880 it we can ship live video for for the 186 00:07:15,670 --> 00:07:13,680 crew to use and also bring down payload 187 00:07:18,629 --> 00:07:15,680 science data through that 188 00:07:21,189 --> 00:07:18,639 ku band link and the six channels is is 189 00:07:23,990 --> 00:07:21,199 a fairly new development it is uh over 190 00:07:26,150 --> 00:07:24,000 the past uh less than a year 191 00:07:27,909 --> 00:07:26,160 early early this year i should say march 192 00:07:29,350 --> 00:07:27,919 april time frame we expanded our 193 00:07:32,230 --> 00:07:29,360 capabilities from four standard 194 00:07:36,790 --> 00:07:32,240 definition downlinks to six combination 195 00:07:36,800 --> 00:07:42,070 thank you you're welcome 196 00:07:47,510 --> 00:07:44,150 hi my name is nicara floyd and i want to 197 00:07:51,670 --> 00:07:47,520 ask you how many tracking and data relay 198 00:07:57,189 --> 00:07:54,309 so the us has uh i believe eight of 199 00:07:59,589 --> 00:07:57,199 these satellites that we can use 200 00:08:02,070 --> 00:07:59,599 what the international space station 201 00:08:04,950 --> 00:08:02,080 uses for communications is only five of 202 00:08:07,110 --> 00:08:04,960 them so we have the options to use five 203 00:08:09,430 --> 00:08:07,120 which are located in various 204 00:08:19,270 --> 00:08:09,440 parts in relation to the earth 205 00:08:22,309 --> 00:08:20,790 and my question is 206 00:08:24,550 --> 00:08:22,319 why does the antenna have to move to 207 00:08:27,110 --> 00:08:24,560 click data 208 00:08:28,629 --> 00:08:27,120 good question um 209 00:08:31,510 --> 00:08:28,639 are they studied up for you yeah they 210 00:08:32,550 --> 00:08:31,520 did they're trying to trying to stump me 211 00:08:35,430 --> 00:08:32,560 um 212 00:08:37,829 --> 00:08:35,440 the antenna has to move because of the 213 00:08:39,430 --> 00:08:37,839 design of the systems basically 214 00:08:40,310 --> 00:08:39,440 we need to get 215 00:08:43,509 --> 00:08:40,320 high 216 00:08:45,030 --> 00:08:43,519 information down 217 00:08:47,110 --> 00:08:45,040 and 218 00:08:49,829 --> 00:08:47,120 the easiest way to explain that is the 219 00:08:52,630 --> 00:08:49,839 higher the information the smaller 220 00:08:53,509 --> 00:08:52,640 the beam width the antenna 221 00:08:58,389 --> 00:08:53,519 can 222 00:08:59,430 --> 00:08:58,399 we have a small beam width a small area 223 00:09:00,790 --> 00:08:59,440 where you can 224 00:09:03,430 --> 00:09:00,800 actually see 225 00:09:05,670 --> 00:09:03,440 uh or transmit the data then you have to 226 00:09:09,030 --> 00:09:05,680 be able to move that small distance to 227 00:09:11,030 --> 00:09:09,040 track the antenna the satellite if we 228 00:09:13,030 --> 00:09:11,040 don't need as big 229 00:09:14,070 --> 00:09:13,040 or if we don't need a high amount of 230 00:09:16,710 --> 00:09:14,080 traffic 231 00:09:19,269 --> 00:09:16,720 we don't need as big of a beam width or 232 00:09:22,070 --> 00:09:19,279 so we can have a bigger beam width 233 00:09:24,949 --> 00:09:22,080 and not have to tr uh move for the 234 00:09:26,310 --> 00:09:24,959 gimbals for our antennas and 235 00:09:27,990 --> 00:09:26,320 i believe part of the reason that the 236 00:09:29,829 --> 00:09:28,000 antennas move too has to do with the 237 00:09:32,630 --> 00:09:29,839 tdrs satellites because you have to 238 00:09:35,190 --> 00:09:32,640 point the antenna at the satellite 239 00:09:37,350 --> 00:09:35,200 the station is moving but the satellites 240 00:09:39,990 --> 00:09:37,360 are not relative exactly 241 00:09:43,829 --> 00:09:40,000 as the tdrs is moving the station is 242 00:09:46,710 --> 00:09:43,839 moving and it all has to be in sync to 243 00:09:48,710 --> 00:09:46,720 lock up to each other we do have some 244 00:09:51,110 --> 00:09:48,720 parts of antennas that we can fail over 245 00:09:54,070 --> 00:09:51,120 to that are considered low rate 246 00:09:56,470 --> 00:09:54,080 that don't move they're they're 247 00:09:58,710 --> 00:09:56,480 par they're like omnidirectional almost 248 00:10:00,310 --> 00:09:58,720 omnidirectional and it gets 249 00:10:02,150 --> 00:10:00,320 part of the sky 250 00:10:03,670 --> 00:10:02,160 but other than that if you want to 251 00:10:05,509 --> 00:10:03,680 transmit about higher amount of data 252 00:10:07,829 --> 00:10:05,519 you're going to have to track the 253 00:10:12,790 --> 00:10:07,839 satellites 254 00:10:17,269 --> 00:10:14,870 hi my name is zachary 255 00:10:18,790 --> 00:10:17,279 i have one question for you 256 00:10:21,269 --> 00:10:18,800 how do you know when airstrikes are 257 00:10:23,190 --> 00:10:21,279 coming to the iss 258 00:10:25,829 --> 00:10:23,200 wow um 259 00:10:28,470 --> 00:10:25,839 yeah the asteroids are our tough one uh 260 00:10:30,550 --> 00:10:28,480 we have uh a specific flight controller 261 00:10:32,550 --> 00:10:30,560 in the room called topo they're in 262 00:10:35,990 --> 00:10:32,560 charge of all the monitoring and the 263 00:10:38,310 --> 00:10:36,000 trajectories of any types of debris or 264 00:10:40,870 --> 00:10:38,320 objects that could impact the space 265 00:10:42,230 --> 00:10:40,880 station and they talk to one of their 266 00:10:44,710 --> 00:10:42,240 counterparts 267 00:10:47,750 --> 00:10:44,720 called stratcom and there 268 00:10:50,150 --> 00:10:47,760 those two positions monitor all the time 269 00:10:51,750 --> 00:10:50,160 whatever is available to see they've got 270 00:10:53,990 --> 00:10:51,760 lots of radar and satellites that they 271 00:10:56,949 --> 00:10:54,000 can monitor this information 272 00:10:59,110 --> 00:10:56,959 and hopefully alert us if we have any 273 00:11:01,430 --> 00:10:59,120 potential asteroids coming now the 274 00:11:04,310 --> 00:11:01,440 smaller the asteroids the harder it is 275 00:11:06,550 --> 00:11:04,320 to monitor and the less notice we get 276 00:11:08,710 --> 00:11:06,560 the harder to see the bigger they are 277 00:11:09,430 --> 00:11:08,720 hopefully we get enough notice to watch 278 00:11:10,630 --> 00:11:09,440 out 279 00:11:12,470 --> 00:11:10,640 and they're watching not just for 280 00:11:13,509 --> 00:11:12,480 asteroids but they're keeping track of 281 00:11:16,230 --> 00:11:13,519 all of the 282 00:11:17,590 --> 00:11:16,240 the junk that's in space there's uh over 283 00:11:20,310 --> 00:11:17,600 the course of 284 00:11:22,310 --> 00:11:20,320 50 years or more as as people have flown 285 00:11:24,710 --> 00:11:22,320 in space and they have left garbage up 286 00:11:26,790 --> 00:11:24,720 there there's more things that are up 287 00:11:29,190 --> 00:11:26,800 there and so we have to keep track of of 288 00:11:30,870 --> 00:11:29,200 even small objects because if they were 289 00:11:32,310 --> 00:11:30,880 to collide with the station they could 290 00:11:33,990 --> 00:11:32,320 cause some damage 291 00:11:35,750 --> 00:11:34,000 yeah you got to understand that all 292 00:11:38,230 --> 00:11:35,760 those objects have a trajectory and a 293 00:11:39,910 --> 00:11:38,240 speed of velocity so 294 00:11:41,910 --> 00:11:39,920 it if we're going in a different 295 00:11:43,750 --> 00:11:41,920 direction than that it could have a real 296 00:11:45,430 --> 00:11:43,760 dire effect and we're traveling really 297 00:11:52,949 --> 00:11:45,440 fast 298 00:11:52,959 --> 00:11:59,829 hi my name is seventh grade 299 00:12:06,710 --> 00:12:03,990 have you ever sent a video to space 300 00:12:09,509 --> 00:12:06,720 have i ever sent a video to space 301 00:12:10,629 --> 00:12:09,519 i can't say that i have sent a video to 302 00:12:12,949 --> 00:12:10,639 space 303 00:12:14,230 --> 00:12:12,959 we ship the astronauts video all the 304 00:12:16,069 --> 00:12:14,240 time 305 00:12:18,310 --> 00:12:16,079 me personally know 306 00:12:20,310 --> 00:12:18,320 we are probably shipping them 307 00:12:22,230 --> 00:12:20,320 video as we speak right now 308 00:12:24,790 --> 00:12:22,240 during the crew off duty day we can ship 309 00:12:26,870 --> 00:12:24,800 them live tv as long as we have that 310 00:12:30,069 --> 00:12:26,880 that link that we talked about between 311 00:12:32,470 --> 00:12:30,079 the satellite and the space station 312 00:12:34,550 --> 00:12:32,480 but no i have never sent video the 313 00:12:36,710 --> 00:12:34,560 closest i've gotten to sending video is 314 00:12:39,269 --> 00:12:36,720 sending a picture up to the astronauts 315 00:12:41,509 --> 00:12:39,279 when my daughter was born in december 316 00:12:43,030 --> 00:12:41,519 and they were pretty stoked about seeing 317 00:12:44,470 --> 00:12:43,040 that and they gave me some 318 00:12:46,949 --> 00:12:44,480 congratulations 319 00:12:48,470 --> 00:12:46,959 but we do send video to the crew all the 320 00:12:51,350 --> 00:12:48,480 time as ken says 321 00:12:53,590 --> 00:12:51,360 they get video that is is training video 322 00:12:54,710 --> 00:12:53,600 that that helps teach them how to do 323 00:12:57,750 --> 00:12:54,720 things 324 00:12:59,430 --> 00:12:57,760 they get video live video from their 325 00:13:01,910 --> 00:12:59,440 families they get a chance to have 326 00:13:04,629 --> 00:13:01,920 weekly video conferences with their 327 00:13:07,590 --> 00:13:04,639 families that usually on the weekends 328 00:13:09,509 --> 00:13:07,600 they can get video from in this room 329 00:13:12,550 --> 00:13:09,519 sometimes of events that happen in this 330 00:13:17,430 --> 00:13:12,560 room that gets sent up to them so uh it 331 00:13:17,440 --> 00:13:23,509 thank you 332 00:13:27,829 --> 00:13:25,590 hello my name is sergey williams and the 333 00:13:30,710 --> 00:13:27,839 question i have for you today is 334 00:13:33,590 --> 00:13:30,720 what would happen if 335 00:13:36,150 --> 00:13:33,600 there was a malfunction in the ia 336 00:13:39,590 --> 00:13:36,160 is internal audio 337 00:13:42,069 --> 00:13:39,600 system during an emergency 338 00:13:45,030 --> 00:13:42,079 and you said that during the internal 339 00:13:46,389 --> 00:13:45,040 audio system during emergency 340 00:13:49,110 --> 00:13:46,399 yeah 341 00:13:51,430 --> 00:13:49,120 interesting question so uh 342 00:13:53,110 --> 00:13:51,440 what would happen during an emergency if 343 00:13:55,030 --> 00:13:53,120 it would depend on the malfunction of 344 00:13:57,670 --> 00:13:55,040 the audio system normally during an 345 00:13:59,350 --> 00:13:57,680 emergency we alert uh 346 00:14:00,870 --> 00:13:59,360 the crew that there is an emergency if 347 00:14:03,990 --> 00:14:00,880 they weren't the ones that detected it 348 00:14:06,069 --> 00:14:04,000 via the tones that are produced by the 349 00:14:07,750 --> 00:14:06,079 audio system 350 00:14:10,470 --> 00:14:07,760 to let them know hey there's emergency 351 00:14:12,230 --> 00:14:10,480 need to take some actions uh if there's 352 00:14:14,230 --> 00:14:12,240 no emergency 353 00:14:16,710 --> 00:14:14,240 and they know about it and there's an 354 00:14:19,590 --> 00:14:16,720 audio malfunction they're trained on the 355 00:14:22,629 --> 00:14:19,600 responses it's almost ingrained we train 356 00:14:26,629 --> 00:14:22,639 their emergency response very hard and 357 00:14:28,069 --> 00:14:26,639 and very often so they'll just go on 358 00:14:29,990 --> 00:14:28,079 muscle memory they'll go to their 359 00:14:31,350 --> 00:14:30,000 procedures and they'll just go perform 360 00:14:32,949 --> 00:14:31,360 the actions 361 00:14:34,550 --> 00:14:32,959 if we don't have a link if we don't have 362 00:14:36,949 --> 00:14:34,560 audio with the crew 363 00:14:38,389 --> 00:14:36,959 hopefully the the failure would be one 364 00:14:40,389 --> 00:14:38,399 where we still 365 00:14:43,350 --> 00:14:40,399 have audio with the crew and we're audit 366 00:14:46,389 --> 00:14:43,360 audited tones but it would impact the 367 00:14:48,870 --> 00:14:46,399 ability for the team on the ground to be 368 00:14:50,550 --> 00:14:48,880 able to follow the crew and for the crew 369 00:14:52,150 --> 00:14:50,560 to be alerted with all their normal 370 00:14:54,790 --> 00:14:52,160 signatures 371 00:14:56,949 --> 00:14:54,800 to rely on the data that's still coming 372 00:14:59,110 --> 00:14:56,959 down but without the ability to talk 373 00:15:01,030 --> 00:14:59,120 exactly 374 00:15:02,150 --> 00:15:01,040 okay 375 00:15:04,949 --> 00:15:02,160 thank you 376 00:15:08,550 --> 00:15:06,949 my name is isaiah perry and i am in the 377 00:15:10,710 --> 00:15:08,560 7th grade 378 00:15:12,790 --> 00:15:10,720 we know that nasa suffered budget cuts 379 00:15:15,030 --> 00:15:12,800 in the past will promise to be affected 380 00:15:16,790 --> 00:15:15,040 by those budget cuts 381 00:15:19,350 --> 00:15:16,800 will kronos be affected by the budget 382 00:15:21,269 --> 00:15:19,360 cuts um 383 00:15:24,230 --> 00:15:21,279 probably in some ways 384 00:15:24,949 --> 00:15:24,240 we've we have already merged with uh 385 00:15:25,829 --> 00:15:24,959 some 386 00:15:30,310 --> 00:15:25,839 we 387 00:15:32,629 --> 00:15:30,320 communication systems and one discipline 388 00:15:34,550 --> 00:15:32,639 and computer and data systems is another 389 00:15:37,749 --> 00:15:34,560 discipline we have since merged into 390 00:15:40,150 --> 00:15:37,759 cronus to combine that i don't foresee 391 00:15:42,470 --> 00:15:40,160 any additional impacts the budget cuts 392 00:15:45,030 --> 00:15:42,480 but it's it's too early to tell i think 393 00:15:51,590 --> 00:15:45,040 i think we're pretty stable 394 00:15:58,629 --> 00:15:54,470 hello my name is gabriela and my 395 00:16:01,829 --> 00:15:58,639 question to you is what is the 396 00:16:05,749 --> 00:16:01,839 what is the machinery you use to send 397 00:16:07,990 --> 00:16:05,759 important information to iss 398 00:16:10,150 --> 00:16:08,000 you said the machinery used to point and 399 00:16:13,030 --> 00:16:10,160 for transmit information i'm not sure 400 00:16:16,150 --> 00:16:13,040 can you repeat the question 401 00:16:19,350 --> 00:16:17,350 what is the 402 00:16:20,629 --> 00:16:19,360 machinery you use 403 00:16:23,990 --> 00:16:20,639 to send 404 00:16:24,790 --> 00:16:24,000 important information to iss 405 00:16:26,870 --> 00:16:24,800 okay 406 00:16:29,110 --> 00:16:26,880 to transmit and receive information 407 00:16:30,710 --> 00:16:29,120 that's that's a good question we use 408 00:16:32,790 --> 00:16:30,720 various pieces of equipment on the 409 00:16:35,509 --> 00:16:32,800 ground our main interface as a flight 410 00:16:37,030 --> 00:16:35,519 controller is our linux workstations you 411 00:16:40,629 --> 00:16:37,040 can kind of see one in the background 412 00:16:43,030 --> 00:16:40,639 here it has command interfaces and 413 00:16:46,069 --> 00:16:43,040 data interfaces and interfaces with the 414 00:16:48,230 --> 00:16:46,079 ground systems so it 415 00:16:51,030 --> 00:16:48,240 puts together what we want to do it 416 00:16:53,509 --> 00:16:51,040 sends it off and puts it into the data 417 00:16:54,790 --> 00:16:53,519 stream and the command stream and at 418 00:16:57,509 --> 00:16:54,800 some point it 419 00:16:59,670 --> 00:16:57,519 it adds the audio information from the 420 00:17:01,590 --> 00:16:59,680 voice channels that we talk to the crew 421 00:17:04,870 --> 00:17:01,600 and then it gets 422 00:17:06,949 --> 00:17:04,880 encrypted and combined and shipped up to 423 00:17:09,829 --> 00:17:06,959 the satellite to shipped over the space 424 00:17:13,110 --> 00:17:09,839 station and receives it's been received 425 00:17:14,870 --> 00:17:13,120 by a satellite dish on our 426 00:17:16,789 --> 00:17:14,880 space station called the 427 00:17:18,470 --> 00:17:16,799 radio frequency uh 428 00:17:19,270 --> 00:17:18,480 gimbal rfg 429 00:17:21,189 --> 00:17:19,280 so 430 00:17:22,789 --> 00:17:21,199 at that point it brings into s-band 431 00:17:24,949 --> 00:17:22,799 system gets 432 00:17:26,789 --> 00:17:24,959 pulled out into uh 433 00:17:28,950 --> 00:17:26,799 it gets decrypted first 434 00:17:32,549 --> 00:17:28,960 and then gets pulled out into audio data 435 00:17:34,630 --> 00:17:32,559 which goes to audio system and uh 436 00:17:36,390 --> 00:17:34,640 the systems data 437 00:17:38,310 --> 00:17:36,400 command data that goes into the main 438 00:17:42,070 --> 00:17:38,320 computer the main computer will then 439 00:17:49,990 --> 00:17:44,830 simple as that simple as 440 00:17:53,510 --> 00:17:51,909 my name's christina 441 00:17:55,669 --> 00:17:53,520 my question is 442 00:17:58,470 --> 00:17:55,679 how are commands and data sent between 443 00:18:00,470 --> 00:17:58,480 mcc and iss 444 00:18:02,789 --> 00:18:00,480 how are commands routed between mcc and 445 00:18:05,029 --> 00:18:02,799 iss we talked a little bit on the 446 00:18:07,590 --> 00:18:05,039 previous question but uh the commands 447 00:18:10,549 --> 00:18:07,600 are we have a set list of commands that 448 00:18:12,950 --> 00:18:10,559 we can choose from that we've tested in 449 00:18:14,470 --> 00:18:12,960 various settings and we can choose it on 450 00:18:16,390 --> 00:18:14,480 our linux workstations and linux 451 00:18:18,390 --> 00:18:16,400 workstations has an application 452 00:18:20,549 --> 00:18:18,400 interface with the command system we 453 00:18:22,710 --> 00:18:20,559 choose a command we 454 00:18:25,909 --> 00:18:22,720 hit you know basically hit we want to 455 00:18:27,430 --> 00:18:25,919 send it it gets added to the stream it 456 00:18:29,350 --> 00:18:27,440 gets combined 457 00:18:32,470 --> 00:18:29,360 with the audio system 458 00:18:35,510 --> 00:18:32,480 it gets encrypted so you know only the 459 00:18:38,390 --> 00:18:35,520 commands we want to send and get 460 00:18:39,350 --> 00:18:38,400 get onto the space station gets added to 461 00:18:41,669 --> 00:18:39,360 um 462 00:18:44,070 --> 00:18:41,679 radio frequency signal it gets embedded 463 00:18:45,990 --> 00:18:44,080 into that and it gets shipped out by 464 00:18:47,590 --> 00:18:46,000 white sands to 465 00:18:50,230 --> 00:18:47,600 the satellite the satellite will then 466 00:18:53,110 --> 00:18:50,240 relay the command the entire stream over 467 00:18:55,430 --> 00:18:53,120 to the s-band system and it'll get you 468 00:18:56,870 --> 00:18:55,440 know pulled out from there and shipped 469 00:18:59,350 --> 00:18:56,880 along where it needs to go the main 470 00:19:01,510 --> 00:18:59,360 computer will detect whether or not the 471 00:19:03,430 --> 00:19:01,520 command is valid and 472 00:19:05,190 --> 00:19:03,440 send it to where its destination is 473 00:19:06,470 --> 00:19:05,200 which is part of the header in the 474 00:19:08,230 --> 00:19:06,480 command field 475 00:19:09,669 --> 00:19:08,240 and it'll go from there we can ship 476 00:19:12,070 --> 00:19:09,679 commands to all different parts of the 477 00:19:14,710 --> 00:19:12,080 space station we can even ship 478 00:19:16,549 --> 00:19:14,720 information between modules between 479 00:19:18,789 --> 00:19:16,559 segments and so forth 480 00:19:20,390 --> 00:19:18,799 and despite the 481 00:19:21,909 --> 00:19:20,400 tearing those commands apart into the 482 00:19:23,510 --> 00:19:21,919 pieces so you know they go where they 483 00:19:25,830 --> 00:19:23,520 need to go i think it's interesting to 484 00:19:27,830 --> 00:19:25,840 note too is as you said that the path 485 00:19:29,669 --> 00:19:27,840 that information takes to get from here 486 00:19:32,630 --> 00:19:29,679 to the station is not a straight line no 487 00:19:35,270 --> 00:19:32,640 it's not it goes from here to new mexico 488 00:19:42,789 --> 00:19:35,280 to the satellite to the station 489 00:19:48,390 --> 00:19:45,430 hello my name is latia polk and 490 00:19:50,150 --> 00:19:48,400 we know that there are several countries 491 00:19:52,870 --> 00:19:50,160 working together 492 00:19:54,470 --> 00:19:52,880 um with the iss we want to know how do 493 00:19:55,990 --> 00:19:54,480 they work together how do we work 494 00:19:57,909 --> 00:19:56,000 together 495 00:20:01,190 --> 00:19:57,919 we there are a lot of countries that 496 00:20:03,350 --> 00:20:01,200 we're working with with iss right now um 497 00:20:05,590 --> 00:20:03,360 how we work together is we have lots of 498 00:20:07,990 --> 00:20:05,600 meetings lots of uh 499 00:20:10,310 --> 00:20:08,000 a lot of get togethers with the 500 00:20:12,390 --> 00:20:10,320 with our partners sometimes we talk to 501 00:20:14,870 --> 00:20:12,400 them over the phone sometimes we talk 502 00:20:18,070 --> 00:20:14,880 over in mission control 503 00:20:21,590 --> 00:20:18,080 to them via telephone systems is what's 504 00:20:23,990 --> 00:20:21,600 called device behind us we can listen to 505 00:20:26,070 --> 00:20:24,000 dozens of loops at any given time 506 00:20:28,070 --> 00:20:26,080 and these are patched into 507 00:20:29,990 --> 00:20:28,080 moscow they're patched into japan 508 00:20:31,990 --> 00:20:30,000 they're patched into europe 509 00:20:34,710 --> 00:20:32,000 patched into alabama 510 00:20:37,110 --> 00:20:34,720 it can be patched almost anywhere so we 511 00:20:38,230 --> 00:20:37,120 could talk to them real time by those 512 00:20:40,149 --> 00:20:38,240 methods 513 00:20:41,990 --> 00:20:40,159 and we have a pretty good relationship 514 00:20:45,029 --> 00:20:42,000 with our partners 515 00:20:47,190 --> 00:20:45,039 some partners uh the russians require 516 00:20:48,950 --> 00:20:47,200 extra translation 517 00:20:51,350 --> 00:20:48,960 because that 518 00:20:53,350 --> 00:20:51,360 we speak english they speak russian 519 00:20:56,310 --> 00:20:53,360 so it requires an extra 520 00:20:58,390 --> 00:20:56,320 person involved and both teams have sets 521 00:21:00,390 --> 00:20:58,400 of translators that assist us so we make 522 00:21:02,630 --> 00:21:00,400 sure we communicate the correct 523 00:21:05,590 --> 00:21:02,640 information to both sides and the other 524 00:21:06,630 --> 00:21:05,600 side receives the correct information 525 00:21:07,909 --> 00:21:06,640 but 526 00:21:09,669 --> 00:21:07,919 we have a pretty good symbiotic 527 00:21:11,750 --> 00:21:09,679 relationship between all the countries 528 00:21:13,990 --> 00:21:11,760 working together and that's as you say 529 00:21:15,669 --> 00:21:14,000 it's 16 different countries now that are 530 00:21:18,789 --> 00:21:15,679 involved and 531 00:21:20,230 --> 00:21:18,799 the the device that you talked about i 532 00:21:21,990 --> 00:21:20,240 know you can't see it too well on 533 00:21:24,070 --> 00:21:22,000 television but from this panel right 534 00:21:25,990 --> 00:21:24,080 here we can punch buttons and through 535 00:21:27,909 --> 00:21:26,000 the headsets that we're wearing we can 536 00:21:30,230 --> 00:21:27,919 talk to not only everybody else in this 537 00:21:34,310 --> 00:21:30,240 room but other people in this building 538 00:21:36,230 --> 00:21:34,320 and in russia and in germany and in 539 00:21:38,230 --> 00:21:36,240 japan and this is the same system that 540 00:21:41,590 --> 00:21:38,240 certain people can talk to those 541 00:21:45,830 --> 00:21:41,600 astronauts up in space right now right 542 00:21:48,310 --> 00:21:46,870 okay 543 00:21:49,830 --> 00:21:48,320 did uh 544 00:21:52,310 --> 00:21:49,840 did we have some more i know some of you 545 00:21:53,830 --> 00:21:52,320 had two questions 546 00:21:57,510 --> 00:21:53,840 do any of you have any additional 547 00:22:00,950 --> 00:21:59,909 all right if i may i'd like to ask a 548 00:22:03,350 --> 00:22:00,960 question 549 00:22:05,110 --> 00:22:03,360 and that is uh 550 00:22:06,789 --> 00:22:05,120 what different career fields are now 551 00:22:08,870 --> 00:22:06,799 everyone thinks of nasa they think of 552 00:22:10,710 --> 00:22:08,880 astronauts and things like that what are 553 00:22:12,630 --> 00:22:10,720 some of the different career fields 554 00:22:14,549 --> 00:22:12,640 available at nasa 555 00:22:16,470 --> 00:22:14,559 well i'm glad you asked that question i 556 00:22:17,750 --> 00:22:16,480 forgot to tell you my back story i'm 557 00:22:19,270 --> 00:22:17,760 actually 558 00:22:20,710 --> 00:22:19,280 i didn't i alluded to it but i'm an 559 00:22:22,310 --> 00:22:20,720 engineer and i actually worked in the 560 00:22:23,909 --> 00:22:22,320 field i studied in the field of 561 00:22:25,430 --> 00:22:23,919 electrical engineering communication 562 00:22:27,830 --> 00:22:25,440 systems 563 00:22:29,350 --> 00:22:27,840 there are a lot of engineers here a lot 564 00:22:31,510 --> 00:22:29,360 of engineers a lot of electrical 565 00:22:34,149 --> 00:22:31,520 engineers or aerospace engineers that 566 00:22:34,950 --> 00:22:34,159 work here some uh 567 00:22:36,390 --> 00:22:34,960 some 568 00:22:39,350 --> 00:22:36,400 people that work here are pure 569 00:22:40,950 --> 00:22:39,360 scientists so pure sciences either 570 00:22:48,230 --> 00:22:40,960 research 571 00:22:50,789 --> 00:22:48,240 payload type science 572 00:22:52,830 --> 00:22:50,799 other fields are 573 00:22:55,590 --> 00:22:52,840 medical fields there's a lot of 574 00:22:58,230 --> 00:22:55,600 medicinal doctor requirements doctors 575 00:23:03,750 --> 00:23:01,669 there are writers there are people who 576 00:23:06,470 --> 00:23:03,760 know about uh 577 00:23:08,789 --> 00:23:06,480 business operations and and 578 00:23:12,149 --> 00:23:08,799 there are people who run the buildings 579 00:23:14,549 --> 00:23:12,159 uh there are all kind of of occupations 580 00:23:17,190 --> 00:23:14,559 who are are needed uh working in nasa 581 00:23:19,029 --> 00:23:17,200 yeah it really takes a whole plethora of 582 00:23:21,510 --> 00:23:19,039 different types and different fields to 583 00:23:23,830 --> 00:23:21,520 work at uh nasa even johnson space 584 00:23:26,310 --> 00:23:23,840 center and it's really diverse 585 00:23:31,830 --> 00:23:26,320 background okay i we have time for one 586 00:23:36,390 --> 00:23:33,830 okay it looks like we we we have 587 00:23:37,750 --> 00:23:36,400 confucia folks okay one question all 588 00:23:38,950 --> 00:23:37,760 right we need to fight come on up i'm 589 00:23:49,669 --> 00:23:38,960 sorry 590 00:23:55,990 --> 00:23:53,750 my question is who designed iss and why 591 00:23:57,909 --> 00:23:56,000 who designed iss and why another good 592 00:23:59,909 --> 00:23:57,919 backstory question though please correct 593 00:24:02,149 --> 00:23:59,919 me if i'm wrong in the short version the 594 00:24:03,590 --> 00:24:02,159 short version is is that uh we were 595 00:24:06,390 --> 00:24:03,600 building a space station called space 596 00:24:09,110 --> 00:24:06,400 station freedom we were planning on one 597 00:24:11,350 --> 00:24:09,120 and moscow or sorry russia had partially 598 00:24:13,590 --> 00:24:11,360 built space station mir ii 599 00:24:15,590 --> 00:24:13,600 and uh europe had proposed a certain 600 00:24:17,909 --> 00:24:15,600 module columbus and we all kind of 601 00:24:20,310 --> 00:24:17,919 decided to pull our resources and and 602 00:24:21,990 --> 00:24:20,320 create an international space station 603 00:24:23,909 --> 00:24:22,000 but uh yeah a lot of people were working 604 00:24:25,590 --> 00:24:23,919 on different things and and it started 605 00:24:27,830 --> 00:24:25,600 to come together as a group back in the 606 00:24:29,110 --> 00:24:27,840 1990s 607 00:24:31,029 --> 00:24:29,120 and i think that's about the time we 608 00:24:32,789 --> 00:24:31,039 have ken i want to thank you for for 609 00:24:34,230 --> 00:24:32,799 joining us here and and some for some 610 00:24:36,070 --> 00:24:34,240 interesting answers and learning about 611 00:24:38,390 --> 00:24:36,080 what's what's going on here and we'll 612 00:24:41,029 --> 00:24:38,400 send it uh we'll send it back to the dln
