1 00:00:05,110 --> 00:00:03,189 welcome to the space flight operations 2 00:00:07,909 --> 00:00:05,120 facility at nasa's jet propulsion 3 00:00:11,270 --> 00:00:07,919 laboratory in pasadena california this 4 00:00:13,669 --> 00:00:11,280 is the home of nasa's deep space network 5 00:00:16,310 --> 00:00:13,679 in this room is the nerve center of the 6 00:00:19,109 --> 00:00:16,320 network of the network that communicates 7 00:00:20,470 --> 00:00:19,119 with spacecraft across the solar system 8 00:00:23,670 --> 00:00:20,480 commands are both sent to those 9 00:00:25,670 --> 00:00:23,680 spacecraft over 30 of them and data is 10 00:00:28,310 --> 00:00:25,680 received here on the ground from those 11 00:00:30,710 --> 00:00:28,320 spacecraft located millions and billions 12 00:00:32,709 --> 00:00:30,720 of miles away from earth 13 00:00:34,229 --> 00:00:32,719 when we say deep space we're not 14 00:00:36,709 --> 00:00:34,239 exaggerating 15 00:00:40,310 --> 00:00:36,719 hello and welcome i'm veronica mcgregor 16 00:00:47,110 --> 00:00:40,320 and this is our 80th nasa social event 17 00:00:50,790 --> 00:00:48,790 we've been holding nasa social events at 18 00:00:53,430 --> 00:00:50,800 nasa centers and in other locations 19 00:00:55,990 --> 00:00:53,440 across the country since 2009 as a way 20 00:00:58,229 --> 00:00:56,000 to bring in the public to see what their 21 00:01:00,630 --> 00:00:58,239 space agency is doing and to spend a day 22 00:01:02,069 --> 00:01:00,640 or even two days behind the scenes 23 00:01:04,950 --> 00:01:02,079 they'll have the opportunity to talk to 24 00:01:06,630 --> 00:01:04,960 the spacecraft engineers the scientists 25 00:01:08,630 --> 00:01:06,640 and the technicians who make the deep 26 00:01:10,630 --> 00:01:08,640 space network operate 27 00:01:13,429 --> 00:01:10,640 you may recognize this particular room 28 00:01:15,590 --> 00:01:13,439 that we're in this is the same room that 29 00:01:19,350 --> 00:01:15,600 the curiosity landing team used in 30 00:01:21,830 --> 00:01:19,360 august of 2012 to watch intently as the 31 00:01:23,510 --> 00:01:21,840 curiosity rover 32 00:01:26,630 --> 00:01:23,520 became closer to mars and then 33 00:01:28,310 --> 00:01:26,640 ultimately safely landed on the planet 34 00:01:30,230 --> 00:01:28,320 uh of course the deep space network is 35 00:01:32,870 --> 00:01:30,240 crucial to all of our spacecraft 36 00:01:34,069 --> 00:01:32,880 operations and you're going to hear 37 00:01:35,429 --> 00:01:34,079 from the people today you're going to 38 00:01:36,870 --> 00:01:35,439 hear from the scientists and engineers 39 00:01:38,390 --> 00:01:36,880 who rely on it 40 00:01:39,990 --> 00:01:38,400 the people in this room get the added 41 00:01:42,069 --> 00:01:40,000 bonus of tomorrow they're going to the 42 00:01:43,990 --> 00:01:42,079 goldstone complex that's located near 43 00:01:46,149 --> 00:01:44,000 barstow california that is one of three 44 00:01:49,830 --> 00:01:46,159 locations around the world where we have 45 00:01:51,270 --> 00:01:49,840 the deep space network antenna and uh 46 00:01:54,950 --> 00:01:51,280 believe me when you're standing in the 47 00:01:56,870 --> 00:01:54,960 shadow of a 230 foot dish you will be 48 00:01:59,109 --> 00:01:56,880 very impressed the pictures absolutely 49 00:02:01,190 --> 00:01:59,119 do not do it justice now for those of 50 00:02:02,630 --> 00:02:01,200 you who are watching on nasa tv or or 51 00:02:04,310 --> 00:02:02,640 the live stream 52 00:02:05,830 --> 00:02:04,320 obviously you can't be with us tomorrow 53 00:02:07,990 --> 00:02:05,840 but i want to tell you that we're using 54 00:02:10,070 --> 00:02:08,000 the hashtag dsn50 55 00:02:11,830 --> 00:02:10,080 so you can follow hopefully everyone 56 00:02:13,670 --> 00:02:11,840 here in the room is going to be 57 00:02:15,510 --> 00:02:13,680 posting a lot to either instagram or 58 00:02:18,390 --> 00:02:15,520 twitter or any of the other social media 59 00:02:19,830 --> 00:02:18,400 platforms follow that hashtag and you'll 60 00:02:21,430 --> 00:02:19,840 be able to see all those pictures both 61 00:02:23,030 --> 00:02:21,440 later today and tomorrow when we're out 62 00:02:24,869 --> 00:02:23,040 there at goldstone 63 00:02:27,350 --> 00:02:24,879 all right so now we're going to start 64 00:02:36,229 --> 00:02:27,360 with a short overview that explains just 65 00:02:41,110 --> 00:02:39,030 deep space network is basically required 66 00:02:43,030 --> 00:02:41,120 to do the kinds of things that we do in 67 00:02:44,869 --> 00:02:43,040 space clearly if you can't talk to your 68 00:02:46,309 --> 00:02:44,879 spacecraft and they can't talk to you 69 00:02:48,710 --> 00:02:46,319 there's no point in even sending them 70 00:02:50,390 --> 00:02:48,720 out there the deep space network makes 71 00:02:51,990 --> 00:02:50,400 everything that we do possible 72 00:02:53,990 --> 00:02:52,000 imagine landing night for example for 73 00:02:55,110 --> 00:02:54,000 curiosity without the deep space network 74 00:02:56,630 --> 00:02:55,120 there'd be no one in there because 75 00:02:58,390 --> 00:02:56,640 there'd be nothing to see we'd hear 76 00:03:00,390 --> 00:02:58,400 nothing from the spacecraft no touchdown 77 00:03:01,990 --> 00:03:00,400 confirmed no cheering no nothing the 78 00:03:04,390 --> 00:03:02,000 deep space network is what helps us 79 00:03:05,910 --> 00:03:04,400 figure out where the spacecraft is we 80 00:03:07,990 --> 00:03:05,920 wouldn't even get close to mars without 81 00:03:10,550 --> 00:03:08,000 it the deep space network comprises of 82 00:03:13,030 --> 00:03:10,560 three complexes around the world placed 83 00:03:14,949 --> 00:03:13,040 about 120 degrees apart we are 84 00:03:17,030 --> 00:03:14,959 constantly in touch with the spacecraft 85 00:03:20,470 --> 00:03:17,040 as the earth rotates 86 00:03:22,390 --> 00:03:20,480 we're today tracking 33 spacecrafts not 87 00:03:24,869 --> 00:03:22,400 only the u.s spacecraft also the 88 00:03:26,789 --> 00:03:24,879 spacecrafts from other countries and 89 00:03:29,350 --> 00:03:26,799 remember this is not only talking to the 90 00:03:32,309 --> 00:03:29,360 spacecraft we have been able to do radar 91 00:03:34,710 --> 00:03:32,319 and radio astronomy and it was the radar 92 00:03:39,190 --> 00:03:34,720 on this antenna that actually was used 93 00:03:43,270 --> 00:03:41,190 these antennas are generally receive 94 00:03:44,949 --> 00:03:43,280 objects but they also use transmit so we 95 00:03:46,550 --> 00:03:44,959 do radar with them we can start to 96 00:03:49,430 --> 00:03:46,560 tolerate their bowlers on the surface of 97 00:03:52,070 --> 00:03:49,440 an asteroid by beaming radar waves and 98 00:03:53,910 --> 00:03:52,080 then getting them back radar provides 99 00:03:55,509 --> 00:03:53,920 hundred thousands times better 100 00:03:57,429 --> 00:03:55,519 understanding of the orbit of one of 101 00:03:58,470 --> 00:03:57,439 these asteroids it's incredibly 102 00:04:00,309 --> 00:03:58,480 important if you want to make sure it's 103 00:04:02,710 --> 00:04:00,319 not coming at us if you look at the 104 00:04:04,949 --> 00:04:02,720 cassini mission we've got a transmitter 105 00:04:07,270 --> 00:04:04,959 about an average of 800 900 million 106 00:04:09,509 --> 00:04:07,280 miles away the transmitter is about the 107 00:04:12,229 --> 00:04:09,519 power of your refrigerator light bulb 108 00:04:14,630 --> 00:04:12,239 and that is what is bringing all these 109 00:04:16,629 --> 00:04:14,640 incredible images and data back i think 110 00:04:18,629 --> 00:04:16,639 it's a resource to be treasured but it's 111 00:04:20,310 --> 00:04:18,639 a resource that also needs to be 112 00:04:22,390 --> 00:04:20,320 nourished 113 00:04:24,469 --> 00:04:22,400 seeing our success in in almost real 114 00:04:26,230 --> 00:04:24,479 time and knowing right away and seeing 115 00:04:32,870 --> 00:04:26,240 those pictures all possible because the 116 00:04:36,629 --> 00:04:34,870 okay so our first speakers today joining 117 00:04:38,150 --> 00:04:36,639 us will be two of the people who are 118 00:04:39,590 --> 00:04:38,160 very well connected with the deep space 119 00:04:42,390 --> 00:04:39,600 network you're gonna hear a lot of cool 120 00:04:45,749 --> 00:04:42,400 titles today uh and here are two first 121 00:04:48,790 --> 00:04:45,759 we have uh joseph lazio he is the chief 122 00:04:51,110 --> 00:04:48,800 scientist for the interplanetary network 123 00:04:53,189 --> 00:04:51,120 and wayne sybil he is the deputy project 124 00:04:55,110 --> 00:04:53,199 manager for the deep space network come 125 00:04:56,629 --> 00:04:55,120 on over they're going to show you share 126 00:04:58,150 --> 00:04:56,639 with you a little bit about what they do 127 00:04:59,830 --> 00:04:58,160 and how this network operates and then 128 00:05:02,230 --> 00:04:59,840 we'll have time for some questions and 129 00:05:03,749 --> 00:05:02,240 answers afterwards 130 00:05:05,590 --> 00:05:03,759 thank you veronica 131 00:05:07,990 --> 00:05:05,600 good morning and thank you for coming um 132 00:05:10,550 --> 00:05:08,000 this is a big year for the dsn 50 years 133 00:05:11,749 --> 00:05:10,560 was celebrated back on december 24th 134 00:05:14,150 --> 00:05:11,759 last year 135 00:05:15,830 --> 00:05:14,160 that was the day 50 years prior to that 136 00:05:17,749 --> 00:05:15,840 that 137 00:05:19,590 --> 00:05:17,759 the lab director at the time dr 138 00:05:20,629 --> 00:05:19,600 pickering established the deep space 139 00:05:23,270 --> 00:05:20,639 network 140 00:05:24,550 --> 00:05:23,280 and from that time on both from apollo 141 00:05:27,430 --> 00:05:24,560 days through 142 00:05:29,510 --> 00:05:27,440 uh curiosity rover 143 00:05:30,710 --> 00:05:29,520 the dsn has been there to make sure that 144 00:05:32,070 --> 00:05:30,720 we have that vital link to the 145 00:05:34,629 --> 00:05:32,080 spacecraft 146 00:05:35,990 --> 00:05:34,639 once it clears the tower at launch 147 00:05:38,390 --> 00:05:36,000 the only way to communicate with these 148 00:05:39,590 --> 00:05:38,400 spacecrafts is through the dsn and the 149 00:05:40,310 --> 00:05:39,600 dsn 150 00:05:42,230 --> 00:05:40,320 is 151 00:05:44,550 --> 00:05:42,240 the only lifeline from the time you get 152 00:05:47,029 --> 00:05:44,560 to the moon and beyond that allows the 153 00:05:49,350 --> 00:05:47,039 commands to get to the spacecraft 154 00:05:52,310 --> 00:05:49,360 allow sequences to be uploaded 155 00:05:54,550 --> 00:05:52,320 allows data to be returned and science 156 00:05:57,189 --> 00:05:54,560 all the science that comes back 157 00:05:59,430 --> 00:05:57,199 wouldn't be possible without the dsn 158 00:06:01,909 --> 00:05:59,440 so let me sort of describe how things 159 00:06:03,749 --> 00:06:01,919 work this is the dark room you guys 160 00:06:05,590 --> 00:06:03,759 were in that dark room a little bit 161 00:06:08,629 --> 00:06:05,600 earlier what you see is the complement 162 00:06:10,469 --> 00:06:08,639 of people we have normally 163 00:06:12,870 --> 00:06:10,479 24 hours a day seven days a week about 164 00:06:14,629 --> 00:06:12,880 five people per shift four to five 165 00:06:15,909 --> 00:06:14,639 and they're the ones that establish the 166 00:06:17,990 --> 00:06:15,919 communication link between the 167 00:06:20,070 --> 00:06:18,000 spacecraft mission controllers wherever 168 00:06:21,749 --> 00:06:20,080 they're located around the world and the 169 00:06:23,110 --> 00:06:21,759 link operators are actually driving the 170 00:06:24,550 --> 00:06:23,120 antenna 171 00:06:26,629 --> 00:06:24,560 those folks will make sure that the 172 00:06:28,550 --> 00:06:26,639 predicts get out to the intended so they 173 00:06:30,150 --> 00:06:28,560 can point properly they'll make sure 174 00:06:32,230 --> 00:06:30,160 that the data flows to and from the 175 00:06:34,469 --> 00:06:32,240 antennas to the missions 176 00:06:36,710 --> 00:06:34,479 they make sure that the data that comes 177 00:06:38,150 --> 00:06:36,720 in gets processed and distributed 178 00:06:39,510 --> 00:06:38,160 throughout the world to the to the 179 00:06:41,510 --> 00:06:39,520 investigators 180 00:06:43,670 --> 00:06:41,520 it's a it's a uh 181 00:06:45,909 --> 00:06:43,680 not a glamorous job but it's a critical 182 00:06:47,350 --> 00:06:45,919 job if they don't do that job 183 00:06:48,629 --> 00:06:47,360 you don't get commands of the spacecraft 184 00:06:51,270 --> 00:06:48,639 tell it to point 185 00:06:54,230 --> 00:06:51,280 to capture a comet to capture uh to 186 00:06:56,629 --> 00:06:54,240 execute a landing so it's a it's a vital 187 00:06:58,230 --> 00:06:56,639 critical job that's handled by just a 188 00:06:59,749 --> 00:06:58,240 few people and they're in the background 189 00:07:01,430 --> 00:06:59,759 you don't really see them 190 00:07:02,790 --> 00:07:01,440 there's probably five people back there 191 00:07:04,390 --> 00:07:02,800 right now 192 00:07:07,510 --> 00:07:04,400 and then around the world the way the 193 00:07:10,469 --> 00:07:07,520 dsm was set up i think i have a graphic 194 00:07:14,150 --> 00:07:10,479 an animation that 195 00:07:19,510 --> 00:07:17,270 the rotation we have a complex in just 196 00:07:21,589 --> 00:07:19,520 outside of camber australia just outside 197 00:07:22,790 --> 00:07:21,599 of madrid spain and out in the goldstone 198 00:07:23,909 --> 00:07:22,800 goldstone is where you'll be tomorrow 199 00:07:26,070 --> 00:07:23,919 and you get a chance to see all the 200 00:07:28,309 --> 00:07:26,080 antennas we have out there but these are 201 00:07:30,550 --> 00:07:28,319 spaced about 120 degrees apart so at any 202 00:07:33,110 --> 00:07:30,560 time any missions that that's at the 203 00:07:35,510 --> 00:07:33,120 moon and beyond we can stay in constant 204 00:07:37,909 --> 00:07:35,520 contact sending commands receiving 205 00:07:38,950 --> 00:07:37,919 information so if a spacecraft gets into 206 00:07:40,390 --> 00:07:38,960 trouble 207 00:07:42,870 --> 00:07:40,400 we're that first line of defense we 208 00:07:45,189 --> 00:07:42,880 notify the missions we we allow them to 209 00:07:46,710 --> 00:07:45,199 start commanding right away 210 00:07:48,629 --> 00:07:46,720 and that's their link that's the only 211 00:07:51,670 --> 00:07:48,639 way that they can survive 212 00:07:53,430 --> 00:07:51,680 and around the world we have 213 00:07:54,550 --> 00:07:53,440 a number of antennas the most direct 214 00:07:56,309 --> 00:07:54,560 gold stone which is where you'll be 215 00:07:57,909 --> 00:07:56,319 tomorrow 216 00:08:00,150 --> 00:07:57,919 we have 217 00:08:01,830 --> 00:08:00,160 the next number in madrid 218 00:08:03,189 --> 00:08:01,840 which is four antennas and then we 219 00:08:05,589 --> 00:08:03,199 currently have three operating antennas 220 00:08:07,830 --> 00:08:05,599 in australia but we're also building two 221 00:08:09,990 --> 00:08:07,840 new antennas in australia 222 00:08:11,670 --> 00:08:10,000 one goes operational this october one 223 00:08:13,270 --> 00:08:11,680 two years later 224 00:08:14,550 --> 00:08:13,280 this will help balance the load between 225 00:08:17,029 --> 00:08:14,560 the northern hemisphere southern 226 00:08:20,070 --> 00:08:17,039 hemisphere so that we can always 227 00:08:22,629 --> 00:08:20,080 make contact with the missions 228 00:08:25,350 --> 00:08:22,639 it's it's it's a great great environment 229 00:08:27,350 --> 00:08:25,360 to work in it's challenging because each 230 00:08:30,150 --> 00:08:27,360 one of these complexes around the world 231 00:08:31,670 --> 00:08:30,160 has their own power generation 232 00:08:33,190 --> 00:08:31,680 they also get commercial power but if 233 00:08:34,949 --> 00:08:33,200 for some reason we don't have commercial 234 00:08:38,070 --> 00:08:34,959 power we can't say 235 00:08:40,870 --> 00:08:38,080 we can't support you project x 236 00:08:42,389 --> 00:08:40,880 so so we have uh generating power to 237 00:08:43,829 --> 00:08:42,399 power the entire complex at each of the 238 00:08:45,509 --> 00:08:43,839 three locations 239 00:08:47,829 --> 00:08:45,519 uh we have a faultless power system at 240 00:08:49,430 --> 00:08:47,839 goldstone in madrid so the power fails 241 00:08:50,870 --> 00:08:49,440 automatically the generators kick in and 242 00:08:53,829 --> 00:08:50,880 the entire complex is picked up on 243 00:08:56,630 --> 00:08:53,839 batteries until the generators spin up 244 00:09:03,110 --> 00:08:59,829 it's manned by probably about 150 people 245 00:09:05,430 --> 00:09:03,120 at goldstone 100 at madrid and 100 at 246 00:09:07,350 --> 00:09:05,440 canberra and they're dedicated to seeing 247 00:09:09,670 --> 00:09:07,360 and making sure the missions are 248 00:09:11,030 --> 00:09:09,680 successful 249 00:09:13,110 --> 00:09:11,040 it's mostly behind the scenes you don't 250 00:09:15,910 --> 00:09:13,120 see the projects 251 00:09:17,350 --> 00:09:15,920 when you when you saw curiosity landing 252 00:09:19,030 --> 00:09:17,360 in this room full of people you didn't 253 00:09:21,829 --> 00:09:19,040 see the dsn but they were behind the 254 00:09:23,590 --> 00:09:21,839 scene making sure it was successful 255 00:09:25,030 --> 00:09:23,600 let me give you uh 256 00:09:26,870 --> 00:09:25,040 dr lazio 257 00:09:29,110 --> 00:09:26,880 to explain a little bit about the 258 00:09:31,110 --> 00:09:29,120 science return and the science that dsn 259 00:09:31,910 --> 00:09:31,120 does thanks wayne 260 00:09:33,190 --> 00:09:31,920 um 261 00:09:35,910 --> 00:09:33,200 wayne has already made this comment i 262 00:09:38,150 --> 00:09:35,920 think veronica's has said it as well but 263 00:09:41,190 --> 00:09:38,160 and you saw it somewhat in that video 264 00:09:42,710 --> 00:09:41,200 essentially any image that we get back 265 00:09:46,949 --> 00:09:42,720 from planets 266 00:09:48,550 --> 00:09:46,959 mars venus mercury jupiter saturn think 267 00:09:51,110 --> 00:09:48,560 juno the spacecraft that's currently on 268 00:09:53,430 --> 00:09:51,120 route to to jupiter new horizons the 269 00:09:55,350 --> 00:09:53,440 spacecraft that's unroot to pluto that 270 00:09:57,509 --> 00:09:55,360 all flows through those antennas and in 271 00:10:00,070 --> 00:09:57,519 fact this graphic is showing the 272 00:10:01,910 --> 00:10:00,080 communications with antennas 273 00:10:04,310 --> 00:10:01,920 with uh well between the antennas and 274 00:10:05,990 --> 00:10:04,320 the spacecraft now the other thing i 275 00:10:08,310 --> 00:10:06,000 want to sort of draw your attention to 276 00:10:10,710 --> 00:10:08,320 you know plant the seed there are some 277 00:10:12,790 --> 00:10:10,720 other uses of these antennas for science 278 00:10:14,389 --> 00:10:12,800 let me give you one example consider 279 00:10:15,829 --> 00:10:14,399 something like mro the mars 280 00:10:17,590 --> 00:10:15,839 reconnaissance orbiter that's actually 281 00:10:18,870 --> 00:10:17,600 orbiting a planet well it's kind of 282 00:10:20,150 --> 00:10:18,880 obvious right when spacecraft goes 283 00:10:22,310 --> 00:10:20,160 behind the planet you can't get the 284 00:10:23,829 --> 00:10:22,320 signal that's a duh 285 00:10:25,350 --> 00:10:23,839 but now suppose the planet has an 286 00:10:28,150 --> 00:10:25,360 atmosphere 287 00:10:30,150 --> 00:10:28,160 as the spacecraft goes behind the signal 288 00:10:31,829 --> 00:10:30,160 has to pass through the atmosphere and 289 00:10:33,190 --> 00:10:31,839 you might worry oh is this going to 290 00:10:34,550 --> 00:10:33,200 cause a problem for the reception of the 291 00:10:36,069 --> 00:10:34,560 signal is it going to somehow corrupt 292 00:10:38,389 --> 00:10:36,079 the signal 293 00:10:40,310 --> 00:10:38,399 or you can turn that around and say hey 294 00:10:42,389 --> 00:10:40,320 if i can track that signal very 295 00:10:43,670 --> 00:10:42,399 accurately i can probe the planet's 296 00:10:45,030 --> 00:10:43,680 atmosphere without actually putting 297 00:10:47,350 --> 00:10:45,040 anything in it 298 00:10:49,750 --> 00:10:47,360 and in fact these antennas are so 299 00:10:51,110 --> 00:10:49,760 sensitive and the tracking is done so 300 00:10:52,550 --> 00:10:51,120 precisely not only can you start 301 00:10:54,310 --> 00:10:52,560 thinking about the atmosphere but 302 00:10:55,829 --> 00:10:54,320 remember the spacecraft moves with 303 00:10:58,710 --> 00:10:55,839 response to the gravity within the 304 00:11:00,389 --> 00:10:58,720 planet right so depending upon how mass 305 00:11:02,470 --> 00:11:00,399 or matter is distributed within the 306 00:11:04,310 --> 00:11:02,480 planet we can actually start to figure 307 00:11:06,630 --> 00:11:04,320 out what the interior of the planet or 308 00:11:08,470 --> 00:11:06,640 the satellite looks like so if you've 309 00:11:11,350 --> 00:11:08,480 ever heard for instance of subsurface 310 00:11:12,870 --> 00:11:11,360 oceans on europa or ganymede some of the 311 00:11:14,870 --> 00:11:12,880 evidence comes from that kind of 312 00:11:16,949 --> 00:11:14,880 spacecraft tracking of as it moves 313 00:11:19,509 --> 00:11:16,959 around the the moon 314 00:11:23,110 --> 00:11:19,519 there's another uh use this particular 315 00:11:24,310 --> 00:11:23,120 antenna the gold dss 14 the the 70 meter 316 00:11:27,110 --> 00:11:24,320 out at goldstone which you'll see 317 00:11:29,030 --> 00:11:27,120 tomorrow sometimes uh actually beams 318 00:11:30,310 --> 00:11:29,040 intense radio waves out we use it for 319 00:11:31,990 --> 00:11:30,320 radar 320 00:11:33,910 --> 00:11:32,000 and you saw in the video they when we 321 00:11:35,190 --> 00:11:33,920 get the reflection you can actually 322 00:11:37,110 --> 00:11:35,200 start making 323 00:11:38,630 --> 00:11:37,120 images equivalent to as if you'd send a 324 00:11:40,230 --> 00:11:38,640 spacecraft there i'm not going to tell 325 00:11:41,750 --> 00:11:40,240 you anything more about that because 326 00:11:43,829 --> 00:11:41,760 marina brockovitz is going to come in 327 00:11:45,269 --> 00:11:43,839 show you some amazing images and again 328 00:11:46,949 --> 00:11:45,279 the other reason that you really care 329 00:11:48,389 --> 00:11:46,959 about that of course is that you get the 330 00:11:49,670 --> 00:11:48,399 orbit very precisely and you want to 331 00:11:51,590 --> 00:11:49,680 know that if there's if there's any 332 00:11:53,590 --> 00:11:51,600 potential issue 333 00:11:54,949 --> 00:11:53,600 uh issue in the sense of is it coming at 334 00:11:57,190 --> 00:11:54,959 us um 335 00:11:59,590 --> 00:11:57,200 the other the other sort of 336 00:12:03,030 --> 00:11:59,600 let me bring this now from the science 337 00:12:04,550 --> 00:12:03,040 to sort of our our uses here at home 338 00:12:07,110 --> 00:12:04,560 perhaps you've had an experience with a 339 00:12:09,030 --> 00:12:07,120 radar gun say you've been at a dodgers 340 00:12:10,629 --> 00:12:09,040 or a washington national chicago cubs 341 00:12:13,030 --> 00:12:10,639 baseball game you've seen the little you 342 00:12:15,590 --> 00:12:13,040 know how fast did the pitcher pitch that 343 00:12:18,870 --> 00:12:15,600 well the kinds of radar that are used in 344 00:12:20,870 --> 00:12:18,880 everyday usage such as sports even 345 00:12:22,710 --> 00:12:20,880 many of those technologies came for 346 00:12:25,110 --> 00:12:22,720 things came from technologies that were 347 00:12:27,430 --> 00:12:25,120 initially either invented at or 348 00:12:29,030 --> 00:12:27,440 developed by the dsn 349 00:12:31,030 --> 00:12:29,040 you see me flashing around this thing 350 00:12:32,310 --> 00:12:31,040 and i see various people with them this 351 00:12:35,269 --> 00:12:32,320 thing is packed with a couple of 352 00:12:37,829 --> 00:12:35,279 different technologies that again either 353 00:12:39,430 --> 00:12:37,839 were invented by or if not invented were 354 00:12:42,470 --> 00:12:39,440 developed here in a way that you could 355 00:12:43,990 --> 00:12:42,480 move it from this precise scientific use 356 00:12:45,269 --> 00:12:44,000 into something that's for commercial 357 00:12:47,110 --> 00:12:45,279 value 358 00:12:48,870 --> 00:12:47,120 and then my final picture 359 00:12:51,190 --> 00:12:48,880 let me step back now from sort of the 360 00:12:54,069 --> 00:12:51,200 science to and the neat technology you 361 00:12:56,069 --> 00:12:54,079 know radar guns and how fast uh pitchers 362 00:12:58,150 --> 00:12:56,079 pitch baseballs think about some of the 363 00:13:00,389 --> 00:12:58,160 greatest moments in human history and 364 00:13:01,430 --> 00:13:00,399 there should be a still showing up here 365 00:13:04,069 --> 00:13:01,440 you know 366 00:13:05,750 --> 00:13:04,079 humans actually setting foot on another 367 00:13:07,350 --> 00:13:05,760 celestial plant us another celestial 368 00:13:10,230 --> 00:13:07,360 world 369 00:13:13,110 --> 00:13:10,240 or the voyager spacecraft we're sort of 370 00:13:15,670 --> 00:13:13,120 on the verge of becoming an interstellar 371 00:13:17,670 --> 00:13:15,680 space-faring civilization 372 00:13:19,829 --> 00:13:17,680 delivered by the dsn 373 00:13:21,110 --> 00:13:19,839 i think we can take some questions now 374 00:13:23,590 --> 00:13:21,120 right okay so we've got a few minutes 375 00:13:25,350 --> 00:13:23,600 for questions and uh if you have one go 376 00:13:26,389 --> 00:13:25,360 ahead and raise your hand uh if you want 377 00:13:27,990 --> 00:13:26,399 to know a little bit more about what 378 00:13:29,910 --> 00:13:28,000 people do day to day here and just wait 379 00:13:31,030 --> 00:13:29,920 for a microphone to come to you alice we 380 00:13:32,230 --> 00:13:31,040 have 381 00:13:34,230 --> 00:13:32,240 you might it might be easier from the 382 00:13:35,670 --> 00:13:34,240 front okay 383 00:13:37,110 --> 00:13:35,680 i got it 384 00:13:38,710 --> 00:13:37,120 all right go ahead thank you 385 00:13:40,949 --> 00:13:38,720 when you're looking at that graphic that 386 00:13:42,230 --> 00:13:40,959 you have up there the animation so when 387 00:13:44,310 --> 00:13:42,240 it's grayed out 388 00:13:46,710 --> 00:13:44,320 what does that mean when you see those 389 00:13:48,710 --> 00:13:46,720 things coming in those waves is that 390 00:13:50,150 --> 00:13:48,720 specifically from one or multiple ones 391 00:13:52,949 --> 00:13:50,160 that means they're active at that time 392 00:13:54,870 --> 00:13:52,959 that means for example on on dss 54 393 00:13:56,389 --> 00:13:54,880 which is in spain a beam waveguide 394 00:14:00,069 --> 00:13:56,399 antenna is currently tracking the soho 395 00:14:01,350 --> 00:14:00,079 spacecraft um it's the the the signal is 396 00:14:04,470 --> 00:14:01,360 you're doing both uplinking and 397 00:14:05,670 --> 00:14:04,480 downlinking at the same time 398 00:14:08,710 --> 00:14:05,680 this 399 00:14:12,629 --> 00:14:10,949 dss-34 down in australia that means 400 00:14:14,470 --> 00:14:12,639 we're tracking two and two spacecraft at 401 00:14:15,509 --> 00:14:14,480 the same time at mars they're sharing 402 00:14:17,509 --> 00:14:15,519 the link 403 00:14:18,870 --> 00:14:17,519 only one can be uplinking at one time 404 00:14:19,910 --> 00:14:18,880 but both are downlinking at the same 405 00:14:21,990 --> 00:14:19,920 time 406 00:14:23,110 --> 00:14:22,000 and this actually this display is 407 00:14:23,910 --> 00:14:23,120 available 408 00:14:25,590 --> 00:14:23,920 from 409 00:14:28,470 --> 00:14:25,600 the web 410 00:14:30,870 --> 00:14:28,480 anybody can have access to it 411 00:14:32,629 --> 00:14:30,880 can i just can i just expand one when 412 00:14:33,750 --> 00:14:32,639 wayne says uplink and downlink is the 413 00:14:35,030 --> 00:14:33,760 command 414 00:14:36,389 --> 00:14:35,040 downlink is the actual data and of 415 00:14:37,910 --> 00:14:36,399 course if it's not obvious the reason 416 00:14:39,829 --> 00:14:37,920 this one can do those two is because 417 00:14:41,350 --> 00:14:39,839 they're both in orbit about mars so the 418 00:14:43,509 --> 00:14:41,360 antenna essentially sees both at the 419 00:14:45,110 --> 00:14:43,519 same time 420 00:14:46,389 --> 00:14:45,120 and also let you know that uh doug 421 00:14:48,150 --> 00:14:46,399 ellison is going to show us a little bit 422 00:14:52,189 --> 00:14:48,160 more about this tool and explain how it 423 00:14:54,470 --> 00:14:52,199 works and it is uh you can find it at 424 00:14:56,870 --> 00:14:54,480 deepspace.jpl.nasa.gov and click on dsn 425 00:14:57,670 --> 00:14:56,880 now so anyone can watch this at home if 426 00:14:59,670 --> 00:14:57,680 you're interested to see which 427 00:15:01,430 --> 00:14:59,680 spacecraft are in communication with 428 00:15:03,269 --> 00:15:01,440 earth at that moment 429 00:15:05,189 --> 00:15:03,279 any other questions 430 00:15:06,629 --> 00:15:05,199 one more okay we'll get the microphone 431 00:15:09,509 --> 00:15:06,639 to you and then 432 00:15:11,030 --> 00:15:09,519 and then we'll come to you next yeah 433 00:15:12,389 --> 00:15:11,040 when i was in the air force used to work 434 00:15:14,629 --> 00:15:12,399 on power production 435 00:15:17,750 --> 00:15:14,639 what kind of uh generator plant do they 436 00:15:19,269 --> 00:15:17,760 have to operate the radio telescopes 437 00:15:21,189 --> 00:15:19,279 like this 438 00:15:23,110 --> 00:15:21,199 well generally with commercial power and 439 00:15:24,629 --> 00:15:23,120 at goldstone i believe it's about 4.5 440 00:15:27,269 --> 00:15:24,639 megawatts is what we take for the entire 441 00:15:29,269 --> 00:15:27,279 complex it 442 00:15:31,509 --> 00:15:29,279 not gigawatts 443 00:15:32,790 --> 00:15:31,519 megawatts and at the overseas complexes 444 00:15:34,389 --> 00:15:32,800 they have fewer antennas and don't have 445 00:15:36,069 --> 00:15:34,399 radar so they don't have the higher 446 00:15:38,829 --> 00:15:36,079 demand so they're closer to two and a 447 00:15:41,590 --> 00:15:38,839 half to three megawatts of power that's 448 00:15:44,230 --> 00:15:41,600 required and is the power plant located 449 00:15:45,430 --> 00:15:44,240 right on site it is yes so if they were 450 00:15:47,350 --> 00:15:45,440 for some reason that you couldn't get 451 00:15:49,269 --> 00:15:47,360 out to the complex they could hunker 452 00:15:51,430 --> 00:15:49,279 down and be powered on their own there's 453 00:15:53,670 --> 00:15:51,440 water there's there they can pretty much 454 00:15:54,949 --> 00:15:53,680 self-sustain like any city 455 00:15:57,430 --> 00:15:54,959 and i understand this room has been 456 00:15:58,870 --> 00:15:57,440 going 24 7 since what year 457 00:16:01,269 --> 00:15:58,880 oh uh 458 00:16:05,030 --> 00:16:02,949 40 years is that right 459 00:16:07,509 --> 00:16:05,040 about 40 years this room has been 460 00:16:09,749 --> 00:16:07,519 operating 24 7 since uh 461 00:16:11,350 --> 00:16:09,759 yeah about 40 years now so and you even 462 00:16:13,189 --> 00:16:11,360 have a backup for this room so i mean 463 00:16:14,069 --> 00:16:13,199 there's redundancy and redundancy in the 464 00:16:15,350 --> 00:16:14,079 system 465 00:16:17,509 --> 00:16:15,360 to make sure 466 00:16:19,749 --> 00:16:17,519 this this area out here the dark room we 467 00:16:22,310 --> 00:16:19,759 actually have a backup facility located 468 00:16:24,150 --> 00:16:22,320 not too far from here by 18 miles away 469 00:16:25,509 --> 00:16:24,160 and should there be some event that 470 00:16:27,670 --> 00:16:25,519 requires you to move out of the san 471 00:16:29,269 --> 00:16:27,680 gabriel valley area we have a facility 472 00:16:32,710 --> 00:16:29,279 out at the goldstone complex where we 473 00:16:35,269 --> 00:16:34,230 and i think the closest that ever 474 00:16:37,910 --> 00:16:35,279 happened was when we had a massive 475 00:16:40,310 --> 00:16:37,920 wildfire burning uh behind jpl a few 476 00:16:42,470 --> 00:16:40,320 years ago but uh but we stayed right we 477 00:16:45,670 --> 00:16:42,480 stayed yeah um only those employees that 478 00:16:47,990 --> 00:16:45,680 had to stay here but um that was a very 479 00:16:50,069 --> 00:16:48,000 close fire okay well we'll have hugo and 480 00:16:52,310 --> 00:16:50,079 then we have one over here so go ahead 481 00:16:54,870 --> 00:16:52,320 what is the transmitted wattage for the 482 00:16:56,710 --> 00:16:54,880 commands going up uh it varies up to 20 483 00:16:58,949 --> 00:16:56,720 kilowatts 484 00:17:01,030 --> 00:16:58,959 uh we have an 80 kilowatt transmitter 485 00:17:03,590 --> 00:17:01,040 that's in development right now so that 486 00:17:06,150 --> 00:17:03,600 if we didn't have i'm sorry if we didn't 487 00:17:08,150 --> 00:17:06,160 have the 70 meter and it's 20 kilowatt 488 00:17:10,069 --> 00:17:08,160 transmitter then we could go to a 34 489 00:17:12,230 --> 00:17:10,079 meter with an 80 kilowatt transmitter 490 00:17:13,510 --> 00:17:12,240 and get the same power to the spacecraft 491 00:17:15,510 --> 00:17:13,520 but that's under development we're going 492 00:17:17,510 --> 00:17:15,520 to be deploying that uh next year at 493 00:17:19,270 --> 00:17:17,520 goldstone the first production unit and 494 00:17:20,470 --> 00:17:19,280 then eventually 495 00:17:21,750 --> 00:17:20,480 over time we'll get it deployed 496 00:17:25,669 --> 00:17:21,760 throughout the network 497 00:17:28,789 --> 00:17:27,350 i had a question about something you 498 00:17:30,070 --> 00:17:28,799 said i thought i heard you say that 499 00:17:32,630 --> 00:17:30,080 we're on the verge of becoming 500 00:17:35,110 --> 00:17:32,640 intergalactic uh interstellar 501 00:17:37,510 --> 00:17:35,120 interstellar that's where i'm at 502 00:17:39,750 --> 00:17:37,520 um so is there some debate on that like 503 00:17:42,390 --> 00:17:39,760 when is voyager 1 officially like 504 00:17:45,510 --> 00:17:42,400 becoming an interstellar 505 00:17:47,029 --> 00:17:45,520 no the only thing i meant by that is 506 00:17:48,310 --> 00:17:47,039 i think there is a consensus now that 507 00:17:49,990 --> 00:17:48,320 voyager 1 508 00:17:52,390 --> 00:17:50,000 is essentially beyond the solar system 509 00:17:55,909 --> 00:17:52,400 it's beyond the strictly 510 00:17:57,029 --> 00:17:55,919 heliopause i believe is the boundary uh 511 00:17:59,510 --> 00:17:57,039 where the 512 00:18:01,029 --> 00:17:59,520 the influence of the sun is no longer 513 00:18:02,310 --> 00:18:01,039 the dominant it's in the interstellar 514 00:18:03,830 --> 00:18:02,320 space but it's essentially only one 515 00:18:05,669 --> 00:18:03,840 spacecraft right 516 00:18:08,310 --> 00:18:05,679 so that's what i sort of mean by on the 517 00:18:09,909 --> 00:18:08,320 verge of voyager 2 will eventually make 518 00:18:12,390 --> 00:18:09,919 it it's not clear if we'll still be in 519 00:18:13,669 --> 00:18:12,400 contact with voyager 2 when it exits 520 00:18:15,990 --> 00:18:13,679 people have been thinking for a long 521 00:18:17,830 --> 00:18:16,000 time about how could we get 522 00:18:18,789 --> 00:18:17,840 spacecraft not just sort of right at the 523 00:18:21,510 --> 00:18:18,799 edge 524 00:18:23,190 --> 00:18:21,520 but actually well out into interstellar 525 00:18:24,710 --> 00:18:23,200 space and and so it's sort of we're on 526 00:18:26,070 --> 00:18:24,720 the verge 527 00:18:27,350 --> 00:18:26,080 you know think back 50 years or 528 00:18:29,190 --> 00:18:27,360 something when we were just starting to 529 00:18:30,789 --> 00:18:29,200 launch spacecraft 530 00:18:32,470 --> 00:18:30,799 we're sort of now just starting to get 531 00:18:34,870 --> 00:18:32,480 beyond the boundary of the solar system 532 00:18:36,710 --> 00:18:34,880 in comparison to the the dozens of of 533 00:18:37,990 --> 00:18:36,720 spacecraft that that we sent throughout 534 00:18:39,590 --> 00:18:38,000 the solar system 535 00:18:43,590 --> 00:18:39,600 cool okay i think i saw one more 536 00:18:46,870 --> 00:18:44,870 yes uh 537 00:18:49,270 --> 00:18:46,880 sorry for asking this question because i 538 00:18:50,789 --> 00:18:49,280 think i'm bringing everybody down on the 539 00:18:53,270 --> 00:18:50,799 earth again 540 00:18:55,110 --> 00:18:53,280 my question is i think everybody's 541 00:18:58,390 --> 00:18:55,120 question these days 542 00:19:01,750 --> 00:18:58,400 is that why we cannot for example nasa 543 00:19:04,070 --> 00:19:01,760 cannot communicate with this lost plane 544 00:19:06,710 --> 00:19:04,080 which is somewhere on earth and but we 545 00:19:08,549 --> 00:19:06,720 can still we can still communicate with 546 00:19:09,430 --> 00:19:08,559 voyager which is 547 00:19:15,270 --> 00:19:09,440 a 548 00:19:18,150 --> 00:19:15,280 between these two technologies our 549 00:19:20,150 --> 00:19:18,160 antennas are pointing up 550 00:19:20,950 --> 00:19:20,160 and we don't have the ability to point 551 00:19:22,310 --> 00:19:20,960 down 552 00:19:25,029 --> 00:19:22,320 uh so there's nothing that we can do 553 00:19:26,789 --> 00:19:25,039 with our tracking network um other 554 00:19:28,230 --> 00:19:26,799 agencies have other assets and i'm sure 555 00:19:29,830 --> 00:19:28,240 they're playing their part in trying to 556 00:19:31,590 --> 00:19:29,840 do that but but we don't have that 557 00:19:33,590 --> 00:19:31,600 ability 558 00:19:35,510 --> 00:19:33,600 all right okay um actually we need to 559 00:19:36,710 --> 00:19:35,520 wrap up um but you know you're gonna 560 00:19:38,310 --> 00:19:36,720 have plenty of time over the next day 561 00:19:39,750 --> 00:19:38,320 and a half to ask some more questions 562 00:19:41,669 --> 00:19:39,760 but we do want to keep the program 563 00:19:44,150 --> 00:19:41,679 moving right now so i want to thank both 564 00:19:45,669 --> 00:19:44,160 wayne and jose flazio for 565 00:19:47,510 --> 00:19:45,679 spending some time with us this morning 566 00:19:55,750 --> 00:19:47,520 and taking some questions from the group 567 00:19:59,669 --> 00:19:58,310 okay um coming up now i'm going to 568 00:20:02,870 --> 00:19:59,679 introduce the 569 00:20:08,470 --> 00:20:02,880 few members of the curiosity landing 570 00:20:12,630 --> 00:20:10,390 i see there are people sitting in our 571 00:20:15,270 --> 00:20:12,640 chairs 572 00:20:17,110 --> 00:20:15,280 they've taken your seats for today um 573 00:20:19,990 --> 00:20:17,120 everyone this is steve collins and 574 00:20:21,430 --> 00:20:20,000 devereaux and bobac ferdoci and 575 00:20:23,430 --> 00:20:21,440 why don't you go ahead and take a spot 576 00:20:25,270 --> 00:20:23,440 at the front of the room this time 577 00:20:27,110 --> 00:20:25,280 instead of behind the console i know 578 00:20:28,470 --> 00:20:27,120 that's a little different for you 579 00:20:29,990 --> 00:20:28,480 and 580 00:20:31,750 --> 00:20:30,000 they're going to explain to you a little 581 00:20:32,950 --> 00:20:31,760 bit about what makes the dsn so 582 00:20:36,230 --> 00:20:32,960 important for them when they're in a 583 00:20:38,070 --> 00:20:36,240 room like this and so to start with that 584 00:20:39,909 --> 00:20:38,080 though we are going to take you back to 585 00:20:48,950 --> 00:20:39,919 landing night please watch the video 586 00:20:54,870 --> 00:20:50,789 things are looking good 587 00:20:59,430 --> 00:20:57,590 enable reports entry interface 588 00:21:00,870 --> 00:20:59,440 at this time it will begin pressurizing 589 00:21:03,029 --> 00:21:00,880 the propulsion system to increase the 590 00:21:03,990 --> 00:21:03,039 thrust of the system uh we'll use that 591 00:21:11,590 --> 00:21:04,000 for all the maneuvering in the 592 00:21:18,950 --> 00:21:13,430 we're standing by for guidance start 593 00:21:23,830 --> 00:21:21,190 beginning to feel the atmosphere 594 00:21:25,590 --> 00:21:23,840 as we go in here 595 00:21:27,669 --> 00:21:25,600 vehicles just reported via tones that it 596 00:21:29,270 --> 00:21:27,679 has started guided entry 597 00:21:32,070 --> 00:21:29,280 at this time the vehicle is beginning to 598 00:21:35,110 --> 00:21:32,080 steer its way to the target 599 00:21:36,310 --> 00:21:35,120 we have seen peak deceleration 600 00:21:37,909 --> 00:21:36,320 that is starting its first bank 601 00:21:39,430 --> 00:21:37,919 rehearsal 602 00:21:52,230 --> 00:21:39,440 uh it is reporting that we are seeing 603 00:21:59,110 --> 00:21:53,990 we should have parachute deploy around 604 00:21:59,120 --> 00:22:02,230 the parachute is deployed 605 00:22:02,240 --> 00:22:05,830 we are decelerating 606 00:22:09,350 --> 00:22:07,750 has separated on the ground 607 00:22:14,310 --> 00:22:09,360 we're down to 90 meters per second at an 608 00:22:14,320 --> 00:22:20,630 standing by for bachelor separation 609 00:22:20,640 --> 00:22:27,750 we are in power flight 610 00:22:31,669 --> 00:22:29,029 we're an altitude of one kilometer 611 00:22:50,230 --> 00:22:33,669 standing by for skype 612 00:22:50,240 --> 00:23:08,310 touchdown confirmed we're safe 613 00:23:08,320 --> 00:23:26,950 wow 614 00:23:26,960 --> 00:23:46,630 oh 615 00:23:46,640 --> 00:24:13,190 got thumbnails 616 00:24:17,430 --> 00:24:15,669 today right now the wheels of curiosity 617 00:24:20,149 --> 00:24:17,440 have begun to blaze the trail for human 618 00:24:22,950 --> 00:24:20,159 footprints on mars this is an amazing 619 00:24:25,909 --> 00:24:22,960 achievement well today on mars history 620 00:24:27,430 --> 00:24:25,919 was made on earth the successful landing 621 00:24:29,909 --> 00:24:27,440 of curiosity 622 00:24:32,230 --> 00:24:29,919 marks what is really an unprecedented 623 00:24:35,350 --> 00:24:32,240 technological tour de force it will 624 00:24:37,029 --> 00:24:35,360 stand as an american point of pride far 625 00:24:39,269 --> 00:24:37,039 into the future 626 00:24:40,390 --> 00:24:39,279 well tonight was was a great drama that 627 00:24:42,149 --> 00:24:40,400 was played 628 00:24:44,470 --> 00:24:42,159 i could only think of the words of teddy 629 00:24:46,549 --> 00:24:44,480 roosevelt as i was sitting there 630 00:24:48,870 --> 00:24:46,559 it is far better to their mighty things 631 00:24:50,870 --> 00:24:48,880 even though we might fail 632 00:25:06,789 --> 00:24:50,880 than to stay in the twilight that knows 633 00:25:06,799 --> 00:25:10,230 who needs a kleenex 634 00:25:15,029 --> 00:25:12,230 i do have them also in the back 635 00:25:16,630 --> 00:25:15,039 i always joke uh we play these for this 636 00:25:17,909 --> 00:25:16,640 uh video for tour groups on many 637 00:25:20,149 --> 00:25:17,919 different occasions and you can always 638 00:25:22,070 --> 00:25:20,159 tell a room full of jbl's because we all 639 00:25:25,830 --> 00:25:22,080 um still live the emotion of that night 640 00:25:27,029 --> 00:25:25,840 don't we um so ann bobbik and steve uh 641 00:25:29,029 --> 00:25:27,039 why don't you 642 00:25:30,470 --> 00:25:29,039 go ahead and talk about what you were 643 00:25:33,430 --> 00:25:30,480 doing that night in this room how the 644 00:25:36,149 --> 00:25:33,440 dsn plays a role in in something like a 645 00:25:38,789 --> 00:25:36,159 landing night a major event like this 646 00:25:40,950 --> 00:25:38,799 uh sure so i was sitting right over here 647 00:25:43,190 --> 00:25:40,960 in the activity lead chairs as you are 648 00:25:44,710 --> 00:25:43,200 um and we were just you know monitoring 649 00:25:46,470 --> 00:25:44,720 telemetry what's amazing about that 650 00:25:48,549 --> 00:25:46,480 night of course is as probably many of 651 00:25:50,549 --> 00:25:48,559 you guys know there was this 14-minute 652 00:25:51,830 --> 00:25:50,559 delay between uh the events actually 653 00:25:53,669 --> 00:25:51,840 happening and the signal we received 654 00:25:55,590 --> 00:25:53,679 here on earth so 655 00:25:57,029 --> 00:25:55,600 what we were kind of seeing was all kind 656 00:25:59,350 --> 00:25:57,039 of post-fact right it was basically like 657 00:26:01,430 --> 00:25:59,360 taking your sats or your gres and just 658 00:26:02,950 --> 00:26:01,440 waiting for the results to happen 659 00:26:04,070 --> 00:26:02,960 so there's kind of this weird feeling in 660 00:26:05,669 --> 00:26:04,080 the room that there's a little bit at 661 00:26:07,590 --> 00:26:05,679 least for me a little bit of like well 662 00:26:09,110 --> 00:26:07,600 it's all done already 663 00:26:11,110 --> 00:26:09,120 but we're just waiting for the results 664 00:26:12,230 --> 00:26:11,120 and you know we had the tones which was 665 00:26:13,750 --> 00:26:12,240 basically the spacecraft talking 666 00:26:15,110 --> 00:26:13,760 directly back to earth 667 00:26:16,230 --> 00:26:15,120 but those cut out just about a minute 668 00:26:18,470 --> 00:26:16,240 before landing because that's when earth 669 00:26:20,390 --> 00:26:18,480 was setting on mars where we were and 670 00:26:22,789 --> 00:26:20,400 then in addition to that we had these 671 00:26:24,310 --> 00:26:22,799 amazing things uh these two orbiters 672 00:26:26,390 --> 00:26:24,320 already at mars odyssey and mars 673 00:26:28,070 --> 00:26:26,400 accounts order that the the rover was 674 00:26:29,430 --> 00:26:28,080 talking to directly as it landed and 675 00:26:30,950 --> 00:26:29,440 we're getting this data back and of 676 00:26:32,390 --> 00:26:30,960 course um you know one of the first 677 00:26:35,430 --> 00:26:32,400 things that we got back from the surface 678 00:26:37,190 --> 00:26:35,440 of mars was this gorgeous picture of us 679 00:26:38,950 --> 00:26:37,200 just settled on the ground our shadow 680 00:26:40,870 --> 00:26:38,960 long shadow being cast and mount sharp 681 00:26:42,470 --> 00:26:40,880 in the distance that's the photo i chose 682 00:26:44,230 --> 00:26:42,480 over there i feel like it's my favorite 683 00:26:45,350 --> 00:26:44,240 photo um 684 00:26:47,190 --> 00:26:45,360 but one of the things i want to tell you 685 00:26:48,310 --> 00:26:47,200 is kind of the long story that how 686 00:26:49,909 --> 00:26:48,320 i got there and one of the things i 687 00:26:51,110 --> 00:26:49,919 started on this project doing was 688 00:26:52,549 --> 00:26:51,120 mission planning 689 00:26:53,750 --> 00:26:52,559 and the first thing 690 00:26:55,909 --> 00:26:53,760 kind of you do as a mission planner is 691 00:26:58,310 --> 00:26:55,919 you start working on what resources you 692 00:27:01,110 --> 00:26:58,320 have and we start talking about okay you 693 00:27:02,390 --> 00:27:01,120 know on the trip to mars we need dsn 694 00:27:04,470 --> 00:27:02,400 passes because we need to communicate 695 00:27:05,669 --> 00:27:04,480 with the rover or to the spacecraft at 696 00:27:07,029 --> 00:27:05,679 the time of course 697 00:27:08,710 --> 00:27:07,039 every day 698 00:27:09,750 --> 00:27:08,720 or maybe three days a week or whatever 699 00:27:11,350 --> 00:27:09,760 and then we need to make sure that we 700 00:27:13,430 --> 00:27:11,360 have good navigation so we understand 701 00:27:15,029 --> 00:27:13,440 exactly where we're headed and how close 702 00:27:16,230 --> 00:27:15,039 we are to our targets 703 00:27:18,950 --> 00:27:16,240 and steve will probably tell you some 704 00:27:20,549 --> 00:27:18,960 exciting stories about that um 705 00:27:21,990 --> 00:27:20,559 and i remember doing this for the first 706 00:27:23,110 --> 00:27:22,000 time and not knowing what was really 707 00:27:24,389 --> 00:27:23,120 happening because it's basically the 708 00:27:26,389 --> 00:27:24,399 first job i had 709 00:27:27,909 --> 00:27:26,399 and you know writing these these 710 00:27:29,590 --> 00:27:27,919 requirements for the deep space network 711 00:27:31,350 --> 00:27:29,600 and asking you know okay like how much 712 00:27:32,630 --> 00:27:31,360 time do i need per week and who's going 713 00:27:33,830 --> 00:27:32,640 to communicate once we're on the surface 714 00:27:35,029 --> 00:27:33,840 is going to be one of the orbiters it's 715 00:27:36,789 --> 00:27:35,039 going to be us 716 00:27:38,870 --> 00:27:36,799 and i wrote this thing out and i deliver 717 00:27:41,350 --> 00:27:38,880 this you know this great you know first 718 00:27:42,870 --> 00:27:41,360 really proud document that says here's 719 00:27:45,110 --> 00:27:42,880 all our requests 720 00:27:47,990 --> 00:27:45,120 and i get it back and someone says why 721 00:27:50,389 --> 00:27:48,000 does it say mars orbit insertion at the 722 00:27:52,389 --> 00:27:50,399 end two years after landing 723 00:27:53,750 --> 00:27:52,399 and i look and i realize that i've gone 724 00:27:55,750 --> 00:27:53,760 through this and submitted this thing 725 00:27:58,950 --> 00:27:55,760 for mars sample return 726 00:28:00,549 --> 00:27:58,960 instead of our our rover 727 00:28:01,750 --> 00:28:00,559 so that was a learning experience for me 728 00:28:04,630 --> 00:28:01,760 but i think one of the things that kind 729 00:28:06,950 --> 00:28:04,640 of amazes me about this and uh was that 730 00:28:08,950 --> 00:28:06,960 really it took you know me roughly nine 731 00:28:10,950 --> 00:28:08,960 years to get from that point to 732 00:28:11,909 --> 00:28:10,960 seeing that picture for the first time 733 00:28:13,590 --> 00:28:11,919 and there's a little bit of a sense of 734 00:28:14,789 --> 00:28:13,600 relief because 735 00:28:17,590 --> 00:28:14,799 seeing that picture meant that i'd done 736 00:28:18,630 --> 00:28:17,600 my job um 737 00:28:19,590 --> 00:28:18,640 i think all of us kind of have that 738 00:28:21,669 --> 00:28:19,600 sense you know like i don't want to be 739 00:28:23,830 --> 00:28:21,679 the guy to screw it up for everybody 740 00:28:25,190 --> 00:28:23,840 um but you know realizing everything 741 00:28:26,630 --> 00:28:25,200 that it takes to get there and one of 742 00:28:27,430 --> 00:28:26,640 the things of course that takes is not 743 00:28:30,310 --> 00:28:27,440 only 744 00:28:32,470 --> 00:28:30,320 um you know a team of people who can 745 00:28:34,630 --> 00:28:32,480 design and implement something like this 746 00:28:36,950 --> 00:28:34,640 but also you know the rover itself with 747 00:28:38,230 --> 00:28:36,960 this communication talking to an orbiter 748 00:28:40,310 --> 00:28:38,240 that is passing overhead that is 749 00:28:41,510 --> 00:28:40,320 relaying data back here to earth all at 750 00:28:43,190 --> 00:28:41,520 the same time 751 00:28:44,549 --> 00:28:43,200 um that's an incredible achievement and 752 00:28:49,029 --> 00:28:44,559 i'm kind of really proud to be a part of 753 00:28:54,789 --> 00:28:51,669 hi there my name is steve collins and 754 00:28:57,110 --> 00:28:54,799 i'm an attitude control engineer 755 00:29:01,590 --> 00:28:57,120 we have a giant machine in the basement 756 00:29:04,950 --> 00:29:03,669 no actually attitude 757 00:29:07,110 --> 00:29:04,960 control 758 00:29:08,389 --> 00:29:07,120 is the part of the spacecraft that keeps 759 00:29:09,510 --> 00:29:08,399 the spacecraft pointed in the right 760 00:29:10,310 --> 00:29:09,520 direction 761 00:29:13,510 --> 00:29:10,320 so 762 00:29:15,430 --> 00:29:13,520 as we're flying curiosity to mars uh we 763 00:29:17,909 --> 00:29:15,440 have to keep the solar arrays pointed 764 00:29:19,510 --> 00:29:17,919 close to the sun so we get power and we 765 00:29:21,669 --> 00:29:19,520 need to keep the antennas that are on 766 00:29:22,630 --> 00:29:21,679 the spacecraft pointed close to earth so 767 00:29:24,830 --> 00:29:22,640 that we 768 00:29:27,590 --> 00:29:24,840 have communications with the 769 00:29:29,830 --> 00:29:27,600 spacecraft and so i'm responsible for 770 00:29:31,590 --> 00:29:29,840 that the all the thrusters and 771 00:29:34,389 --> 00:29:31,600 gyroscopes and star cameras and stuff 772 00:29:36,149 --> 00:29:34,399 like that that do that 773 00:29:37,990 --> 00:29:36,159 also during the mission 774 00:29:39,830 --> 00:29:38,000 the attitude control system is used to 775 00:29:41,830 --> 00:29:39,840 make corrections to the spacecraft's 776 00:29:44,549 --> 00:29:41,840 trajectory 777 00:29:47,190 --> 00:29:44,559 so the spacecraft has to show up at mars 778 00:29:49,350 --> 00:29:47,200 at the top of the atmosphere basically 779 00:29:51,830 --> 00:29:49,360 inside a football field 780 00:29:54,070 --> 00:29:51,840 in order for us to land in the place on 781 00:29:55,110 --> 00:29:54,080 mars that we want to land and to land 782 00:29:57,029 --> 00:29:55,120 safely 783 00:29:59,029 --> 00:29:57,039 and in order to do that we have to 784 00:30:01,190 --> 00:29:59,039 correct the spacecraft's trajectory we 785 00:30:04,070 --> 00:30:01,200 can't just launch it on a rocket from 786 00:30:06,389 --> 00:30:04,080 the earth and hit that tiny little 787 00:30:08,230 --> 00:30:06,399 target all the way at mars 788 00:30:11,269 --> 00:30:08,240 so during the course of the mission 789 00:30:13,350 --> 00:30:11,279 maybe four or five times we make a uh a 790 00:30:15,669 --> 00:30:13,360 correction to the spacecraft's uh 791 00:30:16,710 --> 00:30:15,679 velocity we fire the thrusters for a few 792 00:30:18,630 --> 00:30:16,720 seconds 793 00:30:21,830 --> 00:30:18,640 um there's a there's a little piece of 794 00:30:23,430 --> 00:30:21,840 b-roll here that 795 00:30:24,710 --> 00:30:23,440 shows the spacecraft just as we 796 00:30:26,870 --> 00:30:24,720 separated 797 00:30:30,230 --> 00:30:26,880 from the launch vehicle and i really 798 00:30:31,510 --> 00:30:30,240 like this because you can see um 799 00:30:33,269 --> 00:30:31,520 what's going to happen is the launch 800 00:30:35,750 --> 00:30:33,279 field is going to de-spin and you can 801 00:30:37,830 --> 00:30:35,760 see the motion of the spacecraft as the 802 00:30:39,510 --> 00:30:37,840 launch vehicle despites there 803 00:30:41,750 --> 00:30:39,520 so that's what the spacecraft looks like 804 00:30:44,549 --> 00:30:41,760 in flight and and that's why i i chose 805 00:30:46,310 --> 00:30:44,559 this little picture to show you guys 806 00:30:49,269 --> 00:30:46,320 we very rarely get to see a picture of 807 00:30:51,750 --> 00:30:49,279 the spacecraft actually flying in space 808 00:30:52,950 --> 00:30:51,760 we usually uh you know see it last down 809 00:30:53,990 --> 00:30:52,960 in the clean room and then have to 810 00:30:56,230 --> 00:30:54,000 imagine 811 00:30:59,590 --> 00:30:56,240 it for the rest of the mission 812 00:31:01,190 --> 00:30:59,600 so we spin the spacecraft spins at 2rpm 813 00:31:03,509 --> 00:31:01,200 and if we want to make a correction to 814 00:31:05,830 --> 00:31:03,519 the trajectory we have to fire the 815 00:31:08,549 --> 00:31:05,840 thrusters in a little pulse and we do 816 00:31:11,029 --> 00:31:08,559 that a couple of times each rev as the 817 00:31:13,909 --> 00:31:11,039 spacecraft spins 818 00:31:17,269 --> 00:31:13,919 to tweak the orbit and in order to make 819 00:31:20,310 --> 00:31:17,279 those corrections the deep space network 820 00:31:21,830 --> 00:31:20,320 has to tell us where the spacecraft is 821 00:31:24,070 --> 00:31:21,840 and they do that 822 00:31:26,070 --> 00:31:24,080 by giving us these things that we call 823 00:31:28,710 --> 00:31:26,080 doppels 824 00:31:30,870 --> 00:31:28,720 dopples are the information that's in 825 00:31:33,350 --> 00:31:30,880 the doppler signature of the radio 826 00:31:36,630 --> 00:31:33,360 signal we're getting from the spacecraft 827 00:31:38,310 --> 00:31:36,640 and the dsn can measure uh the frequency 828 00:31:41,430 --> 00:31:38,320 of the radio signal that's coming from 829 00:31:43,029 --> 00:31:41,440 the spacecraft very very accurately we 830 00:31:45,110 --> 00:31:43,039 can measure the velocity of the 831 00:31:47,029 --> 00:31:45,120 spacecraft to like a tenth of a 832 00:31:49,750 --> 00:31:47,039 millimeter per second 833 00:31:50,870 --> 00:31:49,760 and uh we do that pretty much every time 834 00:31:53,750 --> 00:31:50,880 we have communication with the 835 00:31:55,590 --> 00:31:53,760 spacecraft and the navigation team uses 836 00:31:58,230 --> 00:31:55,600 that to figure out where the spacecraft 837 00:32:01,830 --> 00:31:58,240 is in the solar system to within you 838 00:32:03,750 --> 00:32:01,840 know tens of meters and uh and tells us 839 00:32:05,430 --> 00:32:03,760 we want you to change the spacecraft's 840 00:32:08,470 --> 00:32:05,440 velocity by 841 00:32:10,870 --> 00:32:08,480 um let's do eight millimeters per second 842 00:32:13,669 --> 00:32:10,880 today you know our final corrections to 843 00:32:16,789 --> 00:32:13,679 the trajectory are about that size 844 00:32:19,509 --> 00:32:16,799 so that's uh some of the stuff that i uh 845 00:32:22,230 --> 00:32:19,519 work with during flight and do you want 846 00:32:24,310 --> 00:32:22,240 to have your turn and say some things so 847 00:32:25,830 --> 00:32:24,320 i'm ann devereaux um i was actually 848 00:32:28,950 --> 00:32:25,840 sitting where the gentleman with the 849 00:32:29,830 --> 00:32:28,960 gray shirt was on landing night and you 850 00:32:33,990 --> 00:32:29,840 can see 851 00:32:36,470 --> 00:32:34,000 front i was not chief engineer however 852 00:32:37,909 --> 00:32:36,480 if i sidled close to the side because 853 00:32:39,909 --> 00:32:37,919 the chief engineer was roaming the whole 854 00:32:43,509 --> 00:32:39,919 time you might have thought 855 00:32:45,350 --> 00:32:43,519 i was chief engineer for that night um 856 00:32:47,190 --> 00:32:45,360 anyway so i am actually an electrical 857 00:32:50,789 --> 00:32:47,200 engineer my background but like a lot of 858 00:32:52,789 --> 00:32:50,799 people at jpl i have had many hats 859 00:32:54,149 --> 00:32:52,799 my particular disciplines 860 00:32:56,389 --> 00:32:54,159 are telecom 861 00:32:58,950 --> 00:32:56,399 actually i my group were the ones that 862 00:33:02,070 --> 00:32:58,960 built the relay radio elektras that are 863 00:33:04,230 --> 00:33:02,080 on uh msl so when you hear them saying 864 00:33:06,310 --> 00:33:04,240 oh we have uh you know signal from 865 00:33:08,470 --> 00:33:06,320 odyssey that was 866 00:33:10,789 --> 00:33:08,480 our radio the elector radio had talked 867 00:33:13,190 --> 00:33:10,799 to odyssey and odyssey had uh telomered 868 00:33:15,029 --> 00:33:13,200 it to the ground um and so actually it's 869 00:33:16,870 --> 00:33:15,039 not in any of the roles but 870 00:33:19,190 --> 00:33:16,880 randomly i jumped up and i said yeah 871 00:33:20,549 --> 00:33:19,200 elektra because you know until then we 872 00:33:22,470 --> 00:33:20,559 never had to do anything with it i 873 00:33:25,350 --> 00:33:22,480 didn't know it was gonna work i mean i 874 00:33:27,190 --> 00:33:25,360 was hoping um in any case 875 00:33:29,590 --> 00:33:27,200 so uh the other things that i have done 876 00:33:31,350 --> 00:33:29,600 i i was lucky on on msl i was able to 877 00:33:33,509 --> 00:33:31,360 later on move over and be the lead 878 00:33:35,029 --> 00:33:33,519 flight system engineer so that's the 879 00:33:37,430 --> 00:33:35,039 person that's responsible for making 880 00:33:39,110 --> 00:33:37,440 sure as the boxes come in that uh 881 00:33:41,110 --> 00:33:39,120 construct the rover that they are in 882 00:33:42,710 --> 00:33:41,120 fact the box is what we expected and 883 00:33:45,350 --> 00:33:42,720 that when you bolt them all together 884 00:33:47,590 --> 00:33:45,360 they actually do what they you expect 885 00:33:49,990 --> 00:33:47,600 and so that's kind of the trick and part 886 00:33:52,149 --> 00:33:50,000 of that is kind of my last uh field of 887 00:33:53,909 --> 00:33:52,159 expertise which is autonomy uh you know 888 00:33:57,190 --> 00:33:53,919 you heard babic saying you know we have 889 00:33:58,789 --> 00:33:57,200 this giant time delay uh between when uh 890 00:34:00,230 --> 00:33:58,799 you know things actually happen on the 891 00:34:01,590 --> 00:34:00,240 vehicle and when we actually get to see 892 00:34:03,269 --> 00:34:01,600 it on the ground 893 00:34:05,590 --> 00:34:03,279 and it's very much like i actually i 894 00:34:07,669 --> 00:34:05,600 looked up to see what the size of a 895 00:34:09,990 --> 00:34:07,679 tweet was and of course the internet as 896 00:34:11,829 --> 00:34:10,000 usual is confused however it looked like 897 00:34:15,109 --> 00:34:11,839 something like maybe 4k 898 00:34:17,669 --> 00:34:15,119 uh bits was the maximum size for a 899 00:34:20,629 --> 00:34:17,679 message so during entry descent landing 900 00:34:23,589 --> 00:34:20,639 even when we got the the radios online 901 00:34:24,310 --> 00:34:23,599 we were doing eight kilobits per second 902 00:34:26,550 --> 00:34:24,320 so 903 00:34:28,629 --> 00:34:26,560 probably nobody here is tweeting twice a 904 00:34:30,470 --> 00:34:28,639 second that would be kind of fast but if 905 00:34:31,990 --> 00:34:30,480 you think about it that's the kind of 906 00:34:33,829 --> 00:34:32,000 information that we're getting back 907 00:34:36,149 --> 00:34:33,839 basically and it's kind of what 908 00:34:37,589 --> 00:34:36,159 curiosity thinks is important too like i 909 00:34:39,750 --> 00:34:37,599 just did this i just turned on some 910 00:34:41,190 --> 00:34:39,760 heaters i just stopped this i just broke 911 00:34:41,990 --> 00:34:41,200 my arm i just went and you're like what 912 00:34:47,990 --> 00:34:42,000 what 913 00:34:50,710 --> 00:34:48,000 um in the days coming up to edl uh it 914 00:34:53,030 --> 00:34:50,720 was interesting so realistically um we 915 00:34:55,750 --> 00:34:53,040 had sent the command that said literally 916 00:34:58,150 --> 00:34:55,760 i'm not giving any secrets away do edl 917 00:35:00,069 --> 00:34:58,160 something like a week beforehand and re 918 00:35:02,310 --> 00:35:00,079 really the spacecraft and steve can 919 00:35:04,630 --> 00:35:02,320 correct me the state spacecraft because 920 00:35:07,030 --> 00:35:04,640 we had just gotten a good lineup and we 921 00:35:08,710 --> 00:35:07,040 were going on a good uh entry trajectory 922 00:35:11,109 --> 00:35:08,720 the spacecraft could have landed by 923 00:35:13,030 --> 00:35:11,119 itself of course we're the parents right 924 00:35:16,310 --> 00:35:13,040 where the parents you know steadying the 925 00:35:19,190 --> 00:35:16,320 bicycle and we want to help and so from 926 00:35:21,109 --> 00:35:19,200 my kind of autonomy uh hat you know i'd 927 00:35:23,430 --> 00:35:21,119 sit there you know not being chief 928 00:35:24,870 --> 00:35:23,440 engineer i'd sit there and you know i'd 929 00:35:26,069 --> 00:35:24,880 worry well what if something happened we 930 00:35:28,069 --> 00:35:26,079 had these big meetings well what if 931 00:35:30,230 --> 00:35:28,079 something happened you know curiosity 932 00:35:32,150 --> 00:35:30,240 decided she broke her arm now what would 933 00:35:33,510 --> 00:35:32,160 happen is she would tweet i broke my arm 934 00:35:35,750 --> 00:35:33,520 i banded it up it's to the side i'm 935 00:35:36,870 --> 00:35:35,760 ready to go yep headed for mars what we 936 00:35:39,030 --> 00:35:36,880 would be like 937 00:35:40,470 --> 00:35:39,040 what do you broke your arm did you fall 938 00:35:42,230 --> 00:35:40,480 down how about the other arm is the 939 00:35:45,270 --> 00:35:42,240 other arm like we want to ask all these 940 00:35:46,870 --> 00:35:45,280 questions but 14 minutes up 14 minutes 941 00:35:48,310 --> 00:35:46,880 back plus we have to craft the questions 942 00:35:49,510 --> 00:35:48,320 we want to ask plus she's doing a lot of 943 00:35:52,550 --> 00:35:49,520 other stuff she's really busy she's 944 00:35:54,790 --> 00:35:52,560 hurtling toward mars and so it was that 945 00:35:56,870 --> 00:35:54,800 you know the normal human uh instinct 946 00:35:57,990 --> 00:35:56,880 would be to to to you know well what are 947 00:35:59,109 --> 00:35:58,000 you doing now what are you doing now 948 00:36:02,470 --> 00:35:59,119 well i'm going to tweak this and tweak 949 00:36:04,950 --> 00:36:02,480 that and we really had to balance that 950 00:36:07,670 --> 00:36:04,960 against hey she knows what she's doing 951 00:36:09,670 --> 00:36:07,680 you can just let her go but you only get 952 00:36:12,310 --> 00:36:09,680 the information that she sends you and 953 00:36:14,310 --> 00:36:12,320 you only get it because you know we have 954 00:36:16,310 --> 00:36:14,320 the links to the dsn 955 00:36:18,790 --> 00:36:16,320 and you know the relay links which is 956 00:36:20,470 --> 00:36:18,800 you know kind of one step on the way 957 00:36:23,829 --> 00:36:20,480 so it's very interesting for me actually 958 00:36:26,069 --> 00:36:23,839 now i'm working on the next rover the 959 00:36:28,550 --> 00:36:26,079 2020 rover so this is going to be 960 00:36:30,390 --> 00:36:28,560 curiosity's i don't know fraternal twin 961 00:36:32,710 --> 00:36:30,400 uh perhaps we're hoping to reuse a lot 962 00:36:35,430 --> 00:36:32,720 of the same systems and it's interesting 963 00:36:37,109 --> 00:36:35,440 looking back on you know usually at jpl 964 00:36:38,870 --> 00:36:37,119 you know we we do one thing and you move 965 00:36:40,710 --> 00:36:38,880 on you're like wow i'm really glad that 966 00:36:42,150 --> 00:36:40,720 worked yeah let's let's move on and do 967 00:36:43,750 --> 00:36:42,160 something different but now we have this 968 00:36:45,349 --> 00:36:43,760 opportunity to sit and think well you 969 00:36:46,870 --> 00:36:45,359 know was that the right thing you know 970 00:36:48,390 --> 00:36:46,880 maybe we should have thought about 971 00:36:50,230 --> 00:36:48,400 intervening if something happened maybe 972 00:36:52,950 --> 00:36:50,240 we should have done this maybe you know 973 00:36:55,430 --> 00:36:52,960 for for telecommunications for example 974 00:36:56,950 --> 00:36:55,440 um you know we had the the we're so 975 00:36:59,030 --> 00:36:56,960 lucky to have the the good relays 976 00:37:01,589 --> 00:36:59,040 through odyssey and mro mars 977 00:37:04,630 --> 00:37:01,599 reconnaissance orbiter and still now a 978 00:37:07,990 --> 00:37:04,640 basic cadence of curiosity's daily life 979 00:37:09,670 --> 00:37:08,000 is that uh you know odyssey or uh mro 980 00:37:11,030 --> 00:37:09,680 comes up they get all the data you know 981 00:37:12,150 --> 00:37:11,040 she dumps the pictures that sort of 982 00:37:13,829 --> 00:37:12,160 thing 983 00:37:16,150 --> 00:37:13,839 um but you know those orbiters are 984 00:37:17,670 --> 00:37:16,160 getting really old like we actually my 985 00:37:20,310 --> 00:37:17,680 group built the radios which means i'm 986 00:37:22,470 --> 00:37:20,320 getting really old uh that are on mars 987 00:37:26,710 --> 00:37:22,480 reconnaissance orbiter so it launched in 988 00:37:28,310 --> 00:37:26,720 2005. that's like a long time ago so by 989 00:37:31,030 --> 00:37:28,320 the time that we get 990 00:37:33,349 --> 00:37:31,040 to to to mars with 2020 those orbiters 991 00:37:34,790 --> 00:37:33,359 are going to be are going to be very old 992 00:37:36,790 --> 00:37:34,800 and you know we have to think about you 993 00:37:38,230 --> 00:37:36,800 know the dsn has been adding new 994 00:37:40,390 --> 00:37:38,240 capability we're looking at putting on 995 00:37:42,230 --> 00:37:40,400 optical communications and this would be 996 00:37:44,150 --> 00:37:42,240 a new feature of the interplanetary 997 00:37:46,390 --> 00:37:44,160 network that they could receive optical 998 00:37:48,470 --> 00:37:46,400 so we have options like that but only 999 00:37:50,310 --> 00:37:48,480 because you know the evolution of this 1000 00:37:52,950 --> 00:37:50,320 ground system has meant that it can 1001 00:37:55,510 --> 00:37:52,960 adapt you know to what projects need as 1002 00:37:58,150 --> 00:37:55,520 as we go along so oh i have my one 1003 00:37:59,910 --> 00:37:58,160 picture um i just wanted to show so this 1004 00:38:01,510 --> 00:37:59,920 is don't ask me why it's my it's my 1005 00:38:03,430 --> 00:38:01,520 favorite you look at you're like i don't 1006 00:38:05,829 --> 00:38:03,440 even actually know what this is so what 1007 00:38:08,550 --> 00:38:05,839 it is it's it's a picture of her arm 1008 00:38:10,230 --> 00:38:08,560 and it's it's got her name on it and 1009 00:38:11,430 --> 00:38:10,240 there's no one there to see it i mean no 1010 00:38:13,190 --> 00:38:11,440 matter what you see 1011 00:38:15,430 --> 00:38:13,200 in the twitter verse there truly is no 1012 00:38:17,430 --> 00:38:15,440 one to see it it's just her she's by 1013 00:38:18,630 --> 00:38:17,440 herself um and it always has kind of 1014 00:38:20,310 --> 00:38:18,640 struck me like i said you know i have 1015 00:38:21,109 --> 00:38:20,320 this sense of autonomy i have this sense 1016 00:38:23,109 --> 00:38:21,119 of 1017 00:38:24,870 --> 00:38:23,119 her being a person and a personality how 1018 00:38:27,030 --> 00:38:24,880 does she react to things how does she 1019 00:38:29,190 --> 00:38:27,040 like things how does she know how to do 1020 00:38:31,430 --> 00:38:29,200 things um and so i just kind of imagine 1021 00:38:33,510 --> 00:38:31,440 her sitting there you know um and just 1022 00:38:35,109 -->

00:39:03,119 been working this for about eight years 1034 00:39:06,630 --> 00:39:04,880 or so uh what kind of things have you 1035 00:39:08,870 --> 00:39:06,640 learned about yourself 1036 00:39:11,670 --> 00:39:08,880 that you learned while working here and 1037 00:39:13,030 --> 00:39:11,680 uh what you know how does it feel being 1038 00:39:14,790 --> 00:39:13,040 part of history or creating something 1039 00:39:17,430 --> 00:39:14,800 like this so this yeah this was my first 1040 00:39:19,589 --> 00:39:17,440 job out of college um 1041 00:39:22,150 --> 00:39:19,599 you know i liked engineering i thought 1042 00:39:24,630 --> 00:39:22,160 it was cool i wanted to do what i saw 1043 00:39:26,950 --> 00:39:24,640 people had done before with pathfinder 1044 00:39:28,230 --> 00:39:26,960 in like 97 and then the i got here just 1045 00:39:31,109 --> 00:39:28,240 as the mars exploration rovers were 1046 00:39:32,870 --> 00:39:31,119 landing um 1047 00:39:34,230 --> 00:39:32,880 for me i learned a lot about what i like 1048 00:39:35,510 --> 00:39:34,240 as an engineer and what i don't like as 1049 00:39:37,190 --> 00:39:35,520 an engineer i also learned the 1050 00:39:39,030 --> 00:39:37,200 importance of actually working with 1051 00:39:41,030 --> 00:39:39,040 incredibly talented and awesome people 1052 00:39:42,870 --> 00:39:41,040 who make your job fun 1053 00:39:45,109 --> 00:39:42,880 um 1054 00:39:46,470 --> 00:39:45,119 yeah other people other people no uh 1055 00:39:48,150 --> 00:39:46,480 actually absolutely these guys and and 1056 00:39:50,150 --> 00:39:48,160 many other people on this team it's it's 1057 00:39:52,390 --> 00:39:50,160 been an incredible uh journey 1058 00:39:54,390 --> 00:39:52,400 um of kind of just learning 1059 00:39:55,910 --> 00:39:54,400 everything i think i i was lucky enough 1060 00:39:57,349 --> 00:39:55,920 to have some really great mentors on 1061 00:39:59,270 --> 00:39:57,359 this project like charles wetzel and 1062 00:40:00,470 --> 00:39:59,280 people like that who kind of allowed me 1063 00:40:01,750 --> 00:40:00,480 to apprentice i guess a little bit in 1064 00:40:03,349 --> 00:40:01,760 different roles throughout the the 1065 00:40:05,510 --> 00:40:03,359 course of that that time 1066 00:40:07,030 --> 00:40:05,520 um and it's really fun for me i think 1067 00:40:10,230 --> 00:40:07,040 one of the most amazing things is to see 1068 00:40:12,550 --> 00:40:10,240 this project go from really sketches on 1069 00:40:14,470 --> 00:40:12,560 you know paper and powerpoint to 1070 00:40:15,990 --> 00:40:14,480 actually you know those pictures on the 1071 00:40:18,230 --> 00:40:16,000 surface of another planet 1072 00:40:19,990 --> 00:40:18,240 um and i think that you know 1073 00:40:22,309 --> 00:40:20,000 uh people ask is 1074 00:40:24,470 --> 00:40:22,319 10 years is a really long time to get 1075 00:40:25,670 --> 00:40:24,480 that sort of like satisfaction but i'm 1076 00:40:27,430 --> 00:40:25,680 sure everybody who's worked on this 1077 00:40:29,190 --> 00:40:27,440 project for many years would say that 1078 00:40:31,750 --> 00:40:29,200 that investment is totally worth it when 1079 00:40:33,190 --> 00:40:31,760 you see the end results um so i would 1080 00:40:35,109 --> 00:40:33,200 say that despite the fact that sometimes 1081 00:40:35,990 --> 00:40:35,119 this job takes a lot of patience 1082 00:40:37,270 --> 00:40:36,000 um 1083 00:40:39,349 --> 00:40:37,280 you know maybe maybe you would love to 1084 00:40:41,510 --> 00:40:39,359 be on mars every couple years 1085 00:40:42,950 --> 00:40:41,520 uh it it really is tremendously 1086 00:40:44,550 --> 00:40:42,960 rewarding and i think that was that was 1087 00:40:45,270 --> 00:40:44,560 the best thing and i had i mean honestly 1088 00:40:47,910 --> 00:40:45,280 like 1089 00:40:48,950 --> 00:40:47,920 so from a very personal standpoint um 1090 00:40:50,630 --> 00:40:48,960 you know 1091 00:40:51,589 --> 00:40:50,640 there were definitely i think moments 1092 00:40:52,710 --> 00:40:51,599 where i was like 1093 00:40:55,030 --> 00:40:52,720 is it a little ridiculous for me to have 1094 00:40:57,670 --> 00:40:55,040 a mohawk at work or color it 1095 00:40:59,030 --> 00:40:57,680 um and and you know what i i never i 1096 00:41:00,710 --> 00:40:59,040 would say this the one of the greatest 1097 00:41:02,150 --> 00:41:00,720 things i learned about being a part of 1098 00:41:03,589 --> 00:41:02,160 this group was that we were always 1099 00:41:05,430 --> 00:41:03,599 judging the quality of our work and not 1100 00:41:07,030 --> 00:41:05,440 our presentation and how we were as 1101 00:41:08,710 --> 00:41:07,040 people i mean of course being having a 1102 00:41:09,829 --> 00:41:08,720 good team dynamic and 1103 00:41:11,190 --> 00:41:09,839 everything is really important you saw 1104 00:41:12,790 --> 00:41:11,200 us all hugging and high-fiving it's not 1105 00:41:14,230 --> 00:41:12,800 just for show it's because we really you 1106 00:41:16,630 --> 00:41:14,240 know we bonded over the the years 1107 00:41:18,390 --> 00:41:16,640 together so it's been really awesome 1108 00:41:20,390 --> 00:41:18,400 anybody else want to 1109 00:41:21,589 --> 00:41:20,400 answer that while we 1110 00:41:23,589 --> 00:41:21,599 go next 1111 00:41:26,390 --> 00:41:23,599 nope okay let me um 1112 00:41:28,309 --> 00:41:26,400 look for another exactly i agree 1113 00:41:30,230 --> 00:41:28,319 oh we have a microphone right here go 1114 00:41:32,390 --> 00:41:30,240 ahead so um because we're kind of 1115 00:41:34,309 --> 00:41:32,400 talking about a 50-year anniversary like 1116 00:41:35,829 --> 00:41:34,319 my mind is seeing 50 years ago these 1117 00:41:37,910 --> 00:41:35,839 images of just like 1118 00:41:39,670 --> 00:41:37,920 kind of generic balding white guy with 1119 00:41:41,750 --> 00:41:39,680 slick back hair pocket protector big 1120 00:41:44,870 --> 00:41:41,760 thick glasses to now 1121 00:41:47,109 --> 00:41:44,880 like just so much diversity and you guys 1122 00:41:49,349 --> 00:41:47,119 are like literally you three people are 1123 00:41:51,910 --> 00:41:49,359 famous like people millions of people 1124 00:41:52,790 --> 00:41:51,920 know who you are and i just kind of want 1125 00:41:54,390 --> 00:41:52,800 to like 1126 00:41:57,430 --> 00:41:54,400 ask you guys what do you think about 1127 00:41:59,430 --> 00:41:57,440 that like nasa going from this kind of 1128 00:42:00,630 --> 00:41:59,440 kind of elitist club to just like it 1129 00:42:04,069 --> 00:42:00,640 feels like 1130 00:42:06,150 --> 00:42:04,079 like these images like i'm gonna cry but 1131 00:42:08,470 --> 00:42:06,160 like all these images of everybody 1132 00:42:11,190 --> 00:42:08,480 cheering for these spacecraft like what 1133 00:42:12,550 --> 00:42:11,200 do you guys what do you feel about that 1134 00:42:16,550 --> 00:42:12,560 so they handed the microphone to the 1135 00:42:20,710 --> 00:42:18,150 now actually it's interesting so i've 1136 00:42:21,670 --> 00:42:20,720 worked at jpl for 20 years um 1137 00:42:24,470 --> 00:42:21,680 and 1138 00:42:27,750 --> 00:42:24,480 actually i started out uh uh doing some 1139 00:42:30,470 --> 00:42:27,760 work in the dsn and i was like yeah jpm 1140 00:42:33,109 --> 00:42:30,480 dsn oh yeah but i have a job at jpl and 1141 00:42:35,430 --> 00:42:33,119 i don't actually care what it is um but 1142 00:42:36,950 --> 00:42:35,440 i remember seeing safety videos you know 1143 00:42:38,470 --> 00:42:36,960 at the time like oh you know watch how 1144 00:42:41,349 --> 00:42:38,480 to take care of hardware you know 1145 00:42:42,870 --> 00:42:41,359 whatever and i am not kidding it was a 1146 00:42:44,790 --> 00:42:42,880 guy like with a white shirt pocket 1147 00:42:47,349 --> 00:42:44,800 protector black pants i mean this wasn't 1148 00:42:49,270 --> 00:42:47,359 ironic either this was the video and 1149 00:42:51,750 --> 00:42:49,280 he's wearing a coat and it's funny at 1150 00:42:53,589 --> 00:42:51,760 the time so he's got a pipe in his 1151 00:42:55,190 --> 00:42:53,599 pocket 1152 00:42:56,710 --> 00:42:55,200 you do and one of the things that 1153 00:42:58,069 --> 00:42:56,720 they're showing like you know be careful 1154 00:43:00,309 --> 00:42:58,079 that you don't have i mean now we wear 1155 00:43:02,069 --> 00:43:00,319 badges on on on chain and 1156 00:43:03,589 --> 00:43:02,079 i've never done this but you could 1157 00:43:05,270 --> 00:43:03,599 certainly lean over and you know crack 1158 00:43:06,950 --> 00:43:05,280 something with your badge but they show 1159 00:43:08,790 --> 00:43:06,960 this guy leaning over and the pipe's 1160 00:43:10,470 --> 00:43:08,800 coming out and it's like dark and they 1161 00:43:12,710 --> 00:43:10,480 stop him like this and you're like are 1162 00:43:14,950 --> 00:43:12,720 you kidding me are you but it was funny 1163 00:43:16,870 --> 00:43:14,960 when i came actually i mean you know 1164 00:43:18,710 --> 00:43:16,880 back in the day there weren't that many 1165 00:43:21,190 --> 00:43:18,720 women engineers mostly it was the 1166 00:43:23,349 --> 00:43:21,200 administrative staff um and it was an 1167 00:43:25,109 --> 00:43:23,359 interesting uh dynamic for me like every 1168 00:43:26,550 --> 00:43:25,119 once in a while actually still 1169 00:43:28,630 --> 00:43:26,560 i sit in a meeting and i might be the 1170 00:43:30,550 --> 00:43:28,640 one woman and there's 20 guys and it 1171 00:43:32,309 --> 00:43:30,560 just happens to be because that's the 1172 00:43:34,630 --> 00:43:32,319 balance but i think kind of like bobik 1173 00:43:36,470 --> 00:43:34,640 was saying um one of the great things 1174 00:43:39,910 --> 00:43:36,480 about working for nasa is it is about 1175 00:43:42,390 --> 00:43:39,920 your ideas so if i have good ideas i'm 1176 00:43:45,190 --> 00:43:42,400 in the center of the room i can be chief 1177 00:43:46,790 --> 00:43:45,200 engineer not this project maybe but i 1178 00:43:48,150 --> 00:43:46,800 can be chief engineer i can be whatever 1179 00:43:50,230 --> 00:43:48,160 and i know that kind of sounds like a 1180 00:43:52,710 --> 00:43:50,240 platitude but i think certainly my 1181 00:43:54,630 --> 00:43:52,720 experience has been that way and you 1182 00:43:56,230 --> 00:43:54,640 know we have more and more people coming 1183 00:43:58,150 --> 00:43:56,240 in i mean part of it is just education 1184 00:44:00,630 --> 00:43:58,160 right i mean back in the day i had to 1185 00:44:02,550 --> 00:44:00,640 keep saying that you know it wasn't 1186 00:44:03,990 --> 00:44:02,560 a good career path for a woman to go 1187 00:44:06,470 --> 00:44:04,000 into engineering why would you want to 1188 00:44:08,390 --> 00:44:06,480 do that um you didn't see people that 1189 00:44:09,829 --> 00:44:08,400 looked like you whether you were a woman 1190 00:44:11,589 --> 00:44:09,839 whether you were black whether you were 1191 00:44:13,030 --> 00:44:11,599 indian you just didn't see people like 1192 00:44:14,870 --> 00:44:13,040 that so why would you think that that 1193 00:44:16,950 --> 00:44:14,880 was something that you would do and i 1194 00:44:18,790 --> 00:44:16,960 think now there's there's so much less 1195 00:44:20,390 --> 00:44:18,800 of that there's no reason 1196 00:44:21,750 --> 00:44:20,400 you know for people not to understand 1197 00:44:23,990 --> 00:44:21,760 that they can have opportunities in 1198 00:44:26,069 --> 00:44:24,000 science and engineering jpl and 1199 00:44:27,670 --> 00:44:26,079 certainly stephen and bobik and i have 1200 00:44:29,990 --> 00:44:27,680 been very involved in you know getting 1201 00:44:31,349 --> 00:44:30,000 out and doing lectures on science and 1202 00:44:32,950 --> 00:44:31,359 engineering and why it's okay i actually 1203 00:44:34,630 --> 00:44:32,960 get to go to morocco 1204 00:44:36,790 --> 00:44:34,640 last year to give some talks for the 1205 00:44:39,030 --> 00:44:36,800 state department and i tell you the kids 1206 00:44:40,390 --> 00:44:39,040 were looking at me you know blonde white 1207 00:44:42,950 --> 00:44:40,400 woman 1208 00:44:44,390 --> 00:44:42,960 you know like i was from outer space so 1209 00:44:45,750 --> 00:44:44,400 it's very satisfying you know it's just 1210 00:44:47,670 --> 00:44:45,760 a matter of getting the word out that's 1211 00:44:49,510 --> 00:44:47,680 that's the way i feel about it 1212 00:44:50,870 --> 00:44:49,520 um you know i'll actually add something 1213 00:44:52,550 --> 00:44:50,880 to that getting the word out you know 1214 00:44:54,870 --> 00:44:52,560 really what has made these missions so 1215 00:44:57,670 --> 00:44:54,880 popular and them so well known 1216 00:44:59,829 --> 00:44:57,680 is that you all are on social media and 1217 00:45:02,390 --> 00:44:59,839 you have made this kind of work really 1218 00:45:04,790 --> 00:45:02,400 cool again um you know 1219 00:45:06,630 --> 00:45:04,800 in the last five years with twitter and 1220 00:45:08,230 --> 00:45:06,640 all the other social media platforms and 1221 00:45:10,390 --> 00:45:08,240 obviously you guys are following nasa in 1222 00:45:12,390 --> 00:45:10,400 some capacity and maybe on landing night 1223 00:45:14,550 --> 00:45:12,400 you were retweeting the landing but you 1224 00:45:16,630 --> 00:45:14,560 know we have done mission commentary 1225 00:45:18,630 --> 00:45:16,640 like what you saw in that video for 1226 00:45:21,349 --> 00:45:18,640 every single mission going back for 1227 00:45:23,109 --> 00:45:21,359 decades it just didn't get out very well 1228 00:45:24,950 --> 00:45:23,119 it only went to the news media and they 1229 00:45:26,710 --> 00:45:24,960 take you know the 30 minute or 20 sec a 1230 00:45:27,990 --> 00:45:26,720 30-second chunk of it to play in the 1231 00:45:29,990 --> 00:45:28,000 evening news you didn't see all the 1232 00:45:31,510 --> 00:45:30,000 build up in the drama and more in more 1233 00:45:33,990 --> 00:45:31,520 recent years we've been able to stream 1234 00:45:36,390 --> 00:45:34,000 it live uh the entire the entire show 1235 00:45:38,150 --> 00:45:36,400 the entire few hours of commentary and i 1236 00:45:40,230 --> 00:45:38,160 think that has made you have made all 1237 00:45:41,670 --> 00:45:40,240 the difference in the world in terms of 1238 00:45:43,190 --> 00:45:41,680 getting people more familiar with our 1239 00:45:45,109 --> 00:45:43,200 missions and and more familiar with the 1240 00:45:47,430 --> 00:45:45,119 people who are behind them so 1241 00:45:49,589 --> 00:45:47,440 it's thank you guys for doing that 1242 00:45:51,750 --> 00:45:49,599 there's a lot more channels of 1243 00:45:54,150 --> 00:45:51,760 communication now and a lot more options 1244 00:45:56,470 --> 00:45:54,160 for how we can tell the story of how we 1245 00:45:58,550 --> 00:45:56,480 do our stuff 1246 00:46:00,950 --> 00:45:58,560 just to touch on anne's 1247 00:46:04,710 --> 00:46:00,960

00:46:13,030 --> 00:46:09,760 mission the other day and it slowly 1251 00:46:15,510 --> 00:46:13,040 dawned on me that i was the only guy 1252 00:46:18,470 --> 00:46:15,520 in the meeting and i was

super lucky to be able to 1259 00:46:36,230 --> 00:46:34,640 do this fun technical stuff 1260 00:46:38,470 --> 00:46:36,240 be given these very challenging 1261 00:46:41,270 --> 00:46:38,480 technical problems and be able to share 1262 00:46:43,750 --> 00:46:41,280 it with the whole world basically uh 1263 00:46:45,990 --> 00:46:43,760 that they can uh you know ride along and 1264 00:46:47,670 -->

--> 00:47:05,440 all of the space news that's happening i 1274 00:47:09,030 --> 00:47:07,520 remember live tweeting the the landing 1275 00:47:10,790 --> 00:47:09,040 it was one of the most exciting things 1276 00:47:13,349 --> 00:47:10,800 i've ever seen and the excitement that 1277 00:47:15,109 --> 00:47:13,359 was in the room was was palpable across 1278 00:47:17,270 --> 00:47:15,119 the internet which was really really 1279 00:47:20,309 --> 00:47:17,280 amazing um 1280 00:47:22,549 --> 00:47:20,319 now because this social is all about 1281 00:47:25,349 --> 00:47:22,559 communication with spacecraft and with 1282 00:47:27,030 --> 00:47:25,359 curiosity um and of course other 1283 00:47:28,309 --> 00:47:27,040 missions as well 1284 00:47:30,150 --> 00:47:28,319 what 1285 00:47:31,589 --> 00:47:30,160 and i'll say this for for all three of 1286 00:47:34,150 --> 00:47:31,599 you um 1287 00:47:37,349 --> 00:47:34,160 what what's your favorite information 1288 00:47:38,549 --> 00:47:37,359 that's come back from curiosity uh of 1289 00:47:40,549 --> 00:47:38,559 course other than you know hey i've 1290 00:47:43,990 --> 00:47:40,559 landed safely on mars everything's good 1291 00:47:46,549 --> 00:47:44,000 i like the quaternions a lot 1292 00:47:47,829 --> 00:47:46,559 but i'm an attitude control guy 1293 00:47:49,910 --> 00:47:47,839 uh 1294 00:47:52,150 --> 00:47:49,920 just so you get the joke the quaternions 1295 00:47:55,829 --> 00:47:52,160 are four numbers that we use to express 1296 00:47:58,630 --> 00:47:55,839 how the spacecraft is oriented in space 1297 00:48:01,190 --> 00:47:58,640 i spend a lot of my time 1298 00:48:03,430 --> 00:48:01,200 looking at telemetry and 1299 00:48:05,190 --> 00:48:03,440 the dsn streams me 1300 00:48:06,710 --> 00:48:05,200 thousands of numbers that show up on 1301 00:48:07,589 --> 00:48:06,720 these screens that are in front of you 1302 00:48:08,309 --> 00:48:07,599 guys 1303 00:48:13,109 --> 00:48:08,319 and 1304 00:48:15,030 --> 00:48:13,119 we in each of our different subsystems 1305 00:48:17,430 --> 00:48:15,040 make a picture in our mind of what the 1306 00:48:20,549 --> 00:48:17,440 spacecraft is doing out there 1307 00:48:22,470 --> 00:48:20,559 um and so that's the day-to-day thing i 1308 00:48:24,630 --> 00:48:22,480 mean that's what we you know when we're 1309 00:48:26,630 --> 00:48:24,640 not on tv we come in here every day and 1310 00:48:28,549 --> 00:48:26,640 look at our telemetry and figure out is 1311 00:48:30,309 --> 00:48:28,559 the spacecraft okay today that's weird 1312 00:48:31,190 --> 00:48:30,319 what is that little wiggle why did it do 1313 00:48:32,470 --> 00:48:31,200 that 1314 00:48:34,390 --> 00:48:32,480 um 1315 00:48:36,230 --> 00:48:34,400 that that may not be what 1316 00:48:39,190 --> 00:48:36,240 quite you were asking about what's the 1317 00:48:41,670 --> 00:48:39,200 most fascinating science 1318 00:48:44,390 --> 00:48:41,680 uh information from uh from curiosity 1319 00:48:49,589 --> 00:48:44,400 but but that's sort of my day-to-day 1320 00:48:52,870 --> 00:48:51,430 obviously the pictures are amazing i 1321 00:48:54,470 --> 00:48:52,880 think they're very tangible like when 1322 00:48:56,309 --> 00:48:54,480 you see like where we are at kimberly 1323 00:48:57,430 --> 00:48:56,319 these big you know beautiful rocks right 1324 00:48:59,910 --> 00:48:57,440 in front of us mountain shark is in the 1325 00:49:01,670 --> 00:48:59,920 distance it's it's all like and it's for 1326 00:49:03,750 --> 00:49:01,680 me it was very powerful i think to see 1327 00:49:05,510 --> 00:49:03,760 for example pathfinder in 97 to see the 1328 00:49:07,109 --> 00:49:05,520 fact that there's this human-built 1329 00:49:08,790 --> 00:49:07,119 object on a surface another planet makes 1330 00:49:10,069 --> 00:49:08,800 it very just kind of like an experience 1331 00:49:12,309 --> 00:49:10,079 that i feel like i could 1332 00:49:14,150 --> 00:49:12,319 share in um the things that i think i i 1333 00:49:15,750 --> 00:49:14,160 love now i really enjoy the weather 1334 00:49:17,589 --> 00:49:15,760 report and just i don't know why but 1335 00:49:18,790 --> 00:49:17,599 kind of knowing like mars has weather 1336 00:49:21,109 --> 00:49:18,800 and there's temperatures and oh yeah i 1337 00:49:22,309 --> 00:49:21,119 know oh it was cold day on mars today um 1338 00:49:23,750 --> 00:49:22,319 that kind of stuff is actually really 1339 00:49:24,710 --> 00:49:23,760 awesome i know when the sun sets you 1340 00:49:25,990 --> 00:49:24,720 know 1341 00:49:28,470 --> 00:49:26,000 one of the things early on that i 1342 00:49:30,630 --> 00:49:28,480 remember just loving more than anything 1343 00:49:32,950 --> 00:49:30,640 was the way the rover works is every 1344 00:49:35,030 --> 00:49:32,960 morning roughly uh you know 9 30 10 ish 1345 00:49:37,990 --> 00:49:35,040 we send in the the commands for the 1346 00:49:39,750 --> 00:49:38,000 entire day and then in order uh to 1347 00:49:41,349 --> 00:49:39,760 acknowledge that the rover just sends 1348 00:49:43,510 --> 00:49:41,359 out this little beep and it's just a 1349 00:49:45,109 --> 00:49:43,520 tone all is a little tone at the right 1350 00:49:47,109 --> 00:49:45,119 time that tells you hey i got the 1351 00:49:48,309 --> 00:49:47,119 commands today i'm gonna go do this now 1352 00:49:49,829 --> 00:49:48,319 and i don't know why but that just made 1353 00:49:51,589 --> 00:49:49,839 me so happy i'm like oh there it is

back via the mro but that you know 1357 00:49:57,430 --> 00:49:55,920 through going through the deep says 1358 00:50:00,150 --> 00:49:57,440 network we get this little just little 1359 00:50:01,349 --> 00:50:00,160 chirp saying yeah everything is fine 1360 00:50:02,630 --> 00:50:01,359 and it's i don't know why but it just 1361 00:50:03,990 --> 00:50:02,640 made me really happy it was just like

seem to be peanuts 1417 00:51:56,230 --> 00:51:55,200 for some reason 1418 00:51:57,270 --> 00:51:56,240 i i 1419 00:51:59,430 --> 00:51:57,280 i'm 1420 00:52:01,670 --> 00:51:59,440 i may have trouble with knowing the 1421 00:52:02,950 --> 00:52:01,680 whole story but there's a long tradition 1422 00:52:05,510 --> 00:52:02,960 at jpl 1423 00:52:07,109 --> 00:52:05,520 of of having um 1424 00:52:09,510 --> 00:52:07,119 peanuts for 1425 00:52:12,150 --> 00:52:09,520 i think it started with launches and 1426 00:52:14,470 --> 00:52:12,160 then later became kind of any big 1427 00:52:17,270 --> 00:52:14,480 critical event uh that we're doing with 1428 00:52:19,990 --> 00:52:17,280 the spacecraft that for good luck we 1429 00:52:21,589 --> 00:52:20,000 would get out a a bunch of peanuts and 1430 00:52:23,430 --> 00:52:21,599 we'd pass them up and down the rows and 1431 00:52:24,630 --> 00:52:23,440 everybody would eat a couple of peanuts 1432 00:52:27,750 --> 00:52:24,640 yeah i'll tell you a little more about 1433 00:52:30,470 --> 00:52:27,760 the story it was dates back to 1957 and 1434 00:52:33,270 --> 00:52:30,480 uh we were launching a series of 1435 00:52:35,829 --> 00:52:33,280 spacecraft ranger spacecraft at the time 1436 00:52:38,950 --> 00:52:35,839 rangers one through six failed 1437 00:52:40,470 --> 00:52:38,960 ranger seven was a success and everyone 1438 00:52:41,589 --> 00:52:40,480 said well what did we do differently and 1439 00:52:42,710 --> 00:52:41,599 the only thing they could think of that 1440 00:52:44,470 --> 00:52:42,720 had been done differently is someone who 1441 00:52:45,430 --> 00:52:44,480 brought peanuts to mission control that 1442 00:52:47,030 --> 00:52:45,440 day 1443 00:52:48,150 --> 00:52:47,040 just to help people stop being so 1444 00:52:51,030 --> 00:52:48,160 nervous and they had passed around the 1445 00:52:53,030 --> 00:52:51,040 peanuts now so this since 1957 it's been 1446 00:52:54,390 --> 00:52:53,040 a tradition here at jpl as someone else 1447 00:52:57,109 --> 00:52:54,400 will stay say here it's not a 1448 00:53:03,349 --> 00:52:57,119 superstition it's a tradition 1449 00:53:06,390 --> 00:53:04,870 anyways we've got peanuts for each row 1450 00:53:07,670 --> 00:53:06,400 so we're going to put some peanuts on 1451 00:53:09,349 --> 00:53:07,680 the end of each row so you guys can do 1452 00:53:11,589 --> 00:53:09,359 what they do and pass down the peanuts 1453 00:53:13,510 --> 00:53:11,599 during the rest of today thank you all 1454 00:53:15,030 --> 00:53:13,520 so much for coming in and spending time 1455 00:53:16,950 --> 00:53:15,040 talking with them today really 1456 00:53:18,069 --> 00:53:16,960 appreciate it and appreciate all your 1457 00:53:26,309 --> 00:53:18,079 great work 1458 00:53:30,950 --> 00:53:28,870 okay so you've seen this visualization 1459 00:53:33,349 --> 00:53:30,960 going on over here all morning and doug 1460 00:53:34,870 --> 00:53:33,359 ellison was uh instrumental in in 1461 00:53:37,670 --> 00:53:34,880 getting this created and then because it 1462 00:53:39,109 --> 00:53:37,680 used to only be available inside uh jpl 1463 00:53:40,549 --> 00:53:39,119 and now it is available on the internet 1464 00:53:41,990 --> 00:53:40,559 just recently in the last couple of 1465 00:53:43,030 --> 00:53:42,000 weeks right three weeks ago all right 1466 00:53:45,510 --> 00:53:43,040 let you explain it so thank you very 1467 00:53:46,950 --> 00:53:45,520 much so uh welcome everybody the uh the 1468 00:53:48,390 --> 00:53:46,960 the traditional way the deep space 1469 00:53:50,309 --> 00:53:48,400 network would share with the world what 1470 00:53:51,750 --> 00:53:50,319 it was up to and up until about 18 1471 00:53:53,349 --> 00:53:51,760 months two years ago 1472 00:53:54,950 --> 00:53:53,359 was um very much like the gantt chart 1473 00:53:56,470 --> 00:53:54,960 behind that cameraman 1474 00:53:58,309 --> 00:53:56,480 and it's it tells you exactly what the 1475 00:53:59,270 --> 00:53:58,319 network is doing but it takes a while to 1476 00:54:01,349 --> 00:53:59,280 figure out what it's you know what does 1477 00:54:03,190 --> 00:54:01,359 it look like what what what is each line 1478 00:54:04,309 --> 00:54:03,200 what are the colors mean and it's it's a 1479 00:54:06,549 --> 00:54:04,319 glorious way of showing people what the 1480 00:54:09,109 --> 00:54:06,559 network is doing but it's not 1481 00:54:10,630 --> 00:54:09,119 particularly kind of uh intuitive right 1482 00:54:11,910 --> 00:54:10,640 it's not it's not easy to grasp a hold 1483 00:54:13,510 --> 00:54:11,920 of and so 1484 00:54:14,790 --> 00:54:13,520 our team the visualization technology 1485 00:54:16,390 --> 00:54:14,800 application and developments team uh 1486 00:54:18,069 --> 00:54:16,400 here at jpl we worked with some of the 1487 00:54:19,829 --> 00:54:18,079 uh the engineers behind the dsm 1488 00:54:21,109 --> 00:54:19,839 particularly a guy called bark bowie who 1489 00:54:22,549 --> 00:54:21,119 set up some 1490 00:54:24,230 --> 00:54:22,559 some pretty cool pipelines as you can 1491 00:54:25,990 --> 00:54:24,240 imagine getting data about what the 1492 00:54:26,870 --> 00:54:26,000 network itself is doing out to the 1493 00:54:28,309 --> 00:54:26,880 public 1494 00:54:29,750 --> 00:54:28,319 is pretty tricky you've got a lot of 1495 00:54:31,670 --> 00:54:29,760 firewalls to jump through but we've 1496 00:54:32,950 --> 00:54:31,680 managed to make it work now the first 1497 00:54:34,150 --> 00:54:32,960 step was what you've already seen this 1498 00:54:35,430 --> 00:54:34,160 morning we've got this thing working 1499 00:54:36,710 --> 00:54:35,440 here and you'll have seen it up in the 1500 00:54:38,309 --> 00:54:36,720 dark room as well we have these three 1501 00:54:39,829 --> 00:54:38,319 screens that show you all the different 1502 00:54:41,349 --> 00:54:39,839 connections between the antenna and the 1503 00:54:42,870 --> 00:54:41,359 spacecraft and you can see the whole 1504 00:54:44,230 --> 00:54:42,880 different bunch of spacecraft here some 1505 00:54:45,750 --> 00:54:44,240 are gray some are lit up because they're 1506 00:54:47,270 --> 00:54:45,760 actually live connections some are green 1507 00:54:48,870 --> 00:54:47,280 that's the one that's reflected over in 1508 00:54:51,190 --> 00:54:48,880 the co in the big screen at the front of 1509 00:54:53,109 --> 00:54:51,200 the dark room there what we've now done 1510 00:54:54,710 --> 00:54:53,119 is take that and put it online for 1511 00:54:57,030 --> 00:54:54,720 anybody to look at anywhere around the 1512 00:54:57,829 --> 00:54:57,040 world right inside a browser and that's 1513 00:54:59,270 --> 00:54:57,839 what 1514 00:55:01,710 --> 00:54:59,280 the screen is right here so you can get 1515 00:55:03,670 --> 00:55:01,720 to it from the new dsn website at 1516 00:55:04,829 --> 00:55:03,680 deepspace.jpl.nasa.gov or there's a 1517 00:55:07,750 --> 00:55:04,839 quick shortcut for you can go to 1518 00:55:09,510 --> 00:55:07,760 eyes.nasa.gov forward slash dsm i'm sure 1519 00:55:10,549 --> 00:55:09,520 those of you tuning in uh value stream 1520 00:55:11,750 --> 00:55:10,559 and so on and so forth and many of you 1521 00:55:13,270 --> 00:55:11,760 here will have heard about eyes on the 1522 00:55:15,270 --> 00:55:13,280 solar system eyes on the earth eyes on 1523 00:55:17,349 --> 00:55:15,280 exoplanets they all have eyes.nasa.gov 1524 00:55:19,910 --> 00:55:17,359 we'll put a slash dsn on it and you get 1525 00:55:22,230 --> 00:55:19,920 this web page right here and lo and 1526 00:55:23,750 --> 00:55:22,240 behold we hit enter dsn now and we get 1527 00:55:26,069 --> 00:55:23,760 the current view notice they're kind of 1528 00:55:28,069 --> 00:55:26,079 the same right we're now sharing this 1529 00:55:29,510 --> 00:55:28,079 internal dsn view with the general 1530 00:55:30,950 --> 00:55:29,520 public around the globe and you can see 1531 00:55:32,549 --> 00:55:30,960 you've got the dishes at madrid at 1532 00:55:33,510 --> 00:55:32,559 goldstone at canberra in fact this 1533 00:55:35,750 --> 00:55:33,520 version has even got the under 1534 00:55:37,270 --> 00:55:35,760 construction dish 35 down in canberra 1535 00:55:39,510 --> 00:55:37,280 right which will be starting work later 1536 00:55:41,349 --> 00:55:39,520 this year now this is kind of the the 10 1537 00:55:43,349 --> 00:55:41,359 000 view you can see all the different 1538 00:55:45,109 --> 00:55:43,359 connections in real time we can bring up 1539 00:55:46,950 --> 00:55:45,119 the world map that shows you where these 1540 00:55:48,870 --> 00:55:46,960 space these these complexes are around 1541 00:55:50,309 --> 00:55:48,880 the globe in real time with proper 1542 00:55:51,510 --> 00:55:50,319 shading and daytime and night time and 1543 00:55:54,230 --> 00:55:51,520 so on and so forth the different time 1544 00:55:55,990 --> 00:55:54,240 zones for these three complexes but 1545 00:55:57,589 --> 00:55:56,000 where this thing really gets cool is 1546 00:55:58,870 --> 00:55:57,599 kind of the really nerdy detail as far 1547 00:55:59,990 --> 00:55:58,880 as i'm concerned so let's take one 1548 00:56:01,750 --> 00:56:00,000 spacecraft and trigger we've already 1549 00:56:04,549 --> 00:56:01,760 selected up here we can click on soho 1550 00:56:05,750 --> 00:56:04,559 right here soho is a solar observatory 1551 00:56:07,510 --> 00:56:05,760 that lives out 1552 00:56:09,109 --> 00:56:07,520 where the gravity of the sun and the 1553 00:56:13,190 --> 00:56:09,119 earth cancel out so it can observe the 1554 00:56:15,270 --> 00:56:13,200 sun 24 7 365. and this is a simulated 1555 00:56:17,829 --> 00:56:15,280 view of that particular dish pointing in 1556 00:56:19,270 --> 00:56:17,839 that direction at that time of day okay 1557 00:56:22,630 --> 00:56:19,280 we generated the library of something 1558 00:56:24,470 --> 00:56:22,640 like 280 000 images to feed that little 1559 00:56:25,910 --> 00:56:24,480 image in the corner okay 1560 00:56:28,309 --> 00:56:25,920 and we've got some information down here 1561 00:56:29,990 --> 00:56:28,319 soho is 1.29 million k from the earth 1562 00:56:31,270 --> 00:56:30,000 the round trip light time the time it 1563 00:56:34,870 --> 00:56:31,280 takes for radio signal to get to the 1564 00:56:36,870 --> 00:56:34,880 spacecraft and back again is 8.6 seconds 1565 00:56:39,990 --> 00:56:36,880 and you can see it's station 54 it's 1566 00:56:41,670 --> 00:56:40,000 pointing at 264 degrees azimuth and 26.3 1567 00:56:43,510 --> 00:56:41,680 degrees above the horizon you can see 1568 00:56:45,510 --> 00:56:43,520 the weather at the site it's 9.8 sorry 1569 00:56:47,270 --> 00:56:45,520 10.5 it updates every five seconds at 1570 00:56:48,630 --> 00:56:47,280 kilometers per hour where this thing 1571 00:56:50,309 --> 00:56:48,640 gets really cool is when you hit more 1572 00:56:51,750 --> 00:56:50,319 details this is why i really really like 1573 00:56:53,109 --> 00:56:51,760 this tool because you can then start to 1574 00:56:54,390 --> 00:56:53,119 see stuff like 1575 00:56:56,150 --> 00:56:54,400 what sort of data we're getting back 1576 00:56:57,910 --> 00:56:56,160 what frequency it is what power we're 1577 00:56:59,750 --> 00:56:57,920 using so right now so you can see right 1578 00:57:03,109 --> 00:56:59,760 now the soho spacecraft is sending data 1579 00:57:05,750 --> 00:57:03,119 back at 245.7 kilobits per second okay 1580 00:57:07,270 --> 00:57:05,760 that's like isdn speeds early adsl 1581 00:57:08,630 --> 00:57:07,280 speeds let's find something that might 1582 00:57:09,990 --> 00:57:08,640 be talking to us a little bit quicker 1583 00:57:12,150 --> 00:57:10,000 let's find 1584 00:57:13,349 --> 00:57:12,160 uh hopefully mars honestly the mars 1585 00:57:14,630 --> 00:57:13,359 odyssey orbiter may be doing actually a 1586 00:57:16,710 --> 00:57:14,640 little bit slower i'd expect let's see 1587 00:57:19,109 --> 00:57:16,720 what we're getting here 124 kilobits per 1588 00:57:20,069 --> 00:57:19,119 second from mars right now okay 1589 00:57:21,910 --> 00:57:20,079 and 1590 00:57:23,589 --> 00:57:21,920 everyone's favorite without fail is of 1591 00:57:25,829 --> 00:57:23,599 course this guy right down here voyager 1592 00:57:27,109 --> 00:57:25,839 1 has been speaking to us all morning 1593 00:57:28,789 --> 00:57:27,119 and 1594 00:57:31,430 --> 00:57:28,799 you may see some spacecraft in here you 1595 00:57:32,789 --> 00:57:31,440 know 100 kilobits per second 200 1596 00:57:34,549 --> 00:57:32,799 kilobits per second in some cases like 1597 00:57:36,069 --> 00:57:34,559 the miles reconnaissance orbiter 4 1598 00:57:38,390 --> 00:57:36,079 megabits per second you know pretty 1599 00:57:40,549 --> 00:57:38,400 decent communication rates uh voyager 1600 00:57:42,430 --> 00:57:40,559 because it's so far away talks it's a 1601 00:57:45,910 --> 00:57:42,440 little bit slower than that look at this 1602 00:57:47,270 --> 00:57:45,920 18.99 billion kilometers from earth 1603 00:57:48,710 --> 00:57:47,280 the universal is constant to the speed 1604 00:57:50,630 --> 00:57:48,720 of light it takes almost one and a half 1605 00:57:52,150 --> 00:57:50,640 days for a signal to get to and from 1606 00:57:54,230 --> 00:57:52,160 voyages so if we were to send a signal 1607 00:57:56,549 --> 00:57:54,240 to voyager right now we wouldn't get it 1608 00:57:58,309 --> 00:57:56,559 back until about 12 hours from now 1609 00:57:59,430 --> 00:57:58,319 tomorrow okay 1610 00:58:00,470 --> 00:57:59,440 but here's where it gets really 1611 00:58:02,230 --> 00:58:00,480 interesting 1612 00:58:06,150 --> 00:58:02,240 the data rate right down here somewhere 1613 00:58:07,670 --> 00:58:06,160 there it is 160 bits per second 1614 00:58:10,470 --> 00:58:07,680 okay 1615 00:58:12,150 --> 00:58:10,480 um to get a sense of scale it would take 1616 00:58:14,870 --> 00:58:12,160 what we get from kind of some of our 1617 00:58:17,430 --> 00:58:14,880 mars missions it would take voyager 1 a 1618 00:58:19,190 --> 00:58:17,440 couple of thousand years to send back 1619 00:58:20,829 --> 00:58:19,200 what kind of mro has sent back in a year 1620 00:58:23,750 --> 00:58:20,839 or so you know it's incredible data 1621 00:58:25,829 --> 00:58:23,760 rates all of this it's available online 1622 00:58:28,710 --> 00:58:25,839 at is.nasa.gov for sorry yes i used 1623 00:58:30,870 --> 00:58:28,720 master forward slash dsn it's just a web 1624 00:58:33,829 --> 00:58:30,880 page and it's agile design so it works 1625 00:58:35,030 --> 00:58:33,839 on ipads iphones uh android phones and 1626 00:58:36,390 --> 00:58:35,040 so on and so forth works across all 1627 00:58:37,670 --> 00:58:36,400 those different platforms 1628 00:58:38,870 --> 00:58:37,680 and if you've got any time i'll just 1629 00:58:40,390 --> 00:58:38,880 take if anyone got any questions about 1630 00:58:41,910 --> 00:58:40,400 either this screen right here or that 1631 00:58:43,349 --> 00:58:41,920 screen right there or how we made this 1632 00:58:49,030 --> 00:58:43,359 work i'll be happy to take a question or 1633 00:58:51,829 --> 00:58:50,710 i'm just wondering for the classroom 1634 00:58:53,990 --> 00:58:51,839 like if i want to get some of the 1635 00:58:55,510 --> 00:58:54,000 students to plot any data do you have 1636 00:58:57,349 --> 00:58:55,520 data that's available that they could 1637 00:58:58,710 --> 00:58:57,359 bring up so they could plot something 1638 00:58:59,910 --> 00:58:58,720 like an archive of it sort of thing 1639 00:59:01,510 --> 00:58:59,920 right it's something we're looking at 1640 00:59:03,030 --> 00:59:01,520 this is very much a version one and what 1641 00:59:04,950 --> 00:59:03,040 we'd like is people to be able to wind 1642 00:59:06,630 --> 00:59:04,960 back time and say what was it doing five 1643 00:59:08,710 --> 00:59:06,640 minutes ago or an hour ago or so on and 1644 00:59:10,069 --> 00:59:08,720 so forth so uh i hadn't actually with 1645 00:59:11,910 --> 00:59:10,079 our eyes on the earth tool we often get 1646 00:59:12,950 --> 00:59:11,920 questions about can i plot this data 1647 00:59:13,910 --> 00:59:12,960 over time but i hadn't thought about it 1648 00:59:15,750 --> 00:59:13,920 with the dsm that would be pretty 1649 00:59:17,510 --> 00:59:15,760 interesting plotting things like 1650 00:59:18,470 --> 00:59:17,520 frequency or round trip light time and 1651 00:59:19,829 --> 00:59:18,480 so on and so forth that'd be a pretty 1652 00:59:23,430 --> 00:59:19,839 cool thing so we'll definitely keep that 1653 00:59:26,870 --> 00:59:25,430 what does it mean when they turn green 1654 00:59:29,510 --> 00:59:26,880 is that just is that just somebody's 1655 00:59:30,870 --> 00:59:29,520 looking at the data so so this screen is 1656 00:59:32,150 --> 00:59:30,880 actually a mirror of a touch screen 1657 00:59:34,950 --> 00:59:32,160 that's in there and up in the gallery 1658 00:59:36,150 --> 00:59:34,960 where our visitors go and the green one 1659 00:59:37,910 --> 00:59:36,160 is the one that's featured on the other 1660 00:59:39,829 --> 00:59:37,920 two screens in the dark room just over 1661 00:59:41,190 --> 00:59:39,839 there so for example right now we've got 1662 00:59:42,870 --> 00:59:41,200 messenger highlighted here and if you 1663 00:59:43,990 --> 00:59:42,880 look through there the middle screen is 1664 00:59:45,349 --> 00:59:44,000 showing you the dish that's talking to 1665 00:59:46,390 --> 00:59:45,359 messenger and the screen on the right is 1666 00:59:47,910 --> 00:59:46,400 showing you where the messenger 1667 00:59:49,349 --> 00:59:47,920 spacecraft is it's now switched over to 1668 00:59:51,190 --> 00:59:49,359 the european space agency's red desert 1669 00:59:55,270 --> 00:59:51,200 spacecraft just which one is selected 1670 01:00:00,069 --> 00:59:57,190 okay thank you doug thanks so much for 1671 01:00:01,349 --> 01:00:00,079 showing us 1672 01:00:03,109 --> 01:00:01,359 that's the kind of thing i want to have 1673 01:00:04,470 --> 01:00:03,119 on my computer screen all day long just 1674 01:00:06,470 --> 01:00:04,480 up in that top corner i think it's so 1675 01:00:08,470 --> 01:00:06,480 cool uh to know what spacecraft are 1676 01:00:09,910 --> 01:00:08,480 communicating right now all right so now 1677 01:00:11,910 --> 01:00:09,920 we have a very special guest from nasa 1678 01:00:15,750 --> 01:00:11,920 headquarters joining us today this is 1679 01:00:17,750 --> 01:00:15,760 badre eunice and he is nasa's associate 1680 01:00:20,789 --> 01:00:17,760 administrator for space communications 1681 01:00:22,230 --> 01:00:20,799 and navigation and he wanted to uh greet 1682 01:00:25,910 --> 01:00:22,240 you all and and tell you a little more 1683 01:00:27,589 --> 01:00:25,920 about the dsn go ahead yeah 1684 01:00:30,069 --> 01:00:27,599 yeah it's on it's a minor correction i'm 1685 01:00:30,870 --> 01:00:30,079 a deputy associate administrator but i 1686 01:00:33,190 --> 01:00:30,880 have 1687 01:00:35,030 --> 01:00:33,200 the overall responsibility for all space 1688 01:00:38,230 --> 01:00:35,040 calm and navigations 1689 01:00:39,430 --> 01:00:38,240 um behind all of what you have seen are 1690 01:00:41,349 --> 01:00:39,440 people 1691 01:00:44,470 --> 01:00:41,359 dedicated team 1692 01:00:47,190 --> 01:00:44,480 of technicians engineers scientists who 1693 01:00:48,069 --> 01:00:47,200 made all all this possible 1694 01:00:49,349 --> 01:00:48,079 you know 1695 01:00:51,670 --> 01:00:49,359 what 1696 01:00:54,710 --> 01:00:51,680 they've done is enabling science to take 1697 01:00:57,829 --> 01:00:54,720 place exploration to proceed 1698 01:01:00,710 --> 01:00:57,839 return the kind of data from all of our 1699 01:01:02,789 --> 01:01:00,720 planets in our solar systems 1700 01:01:05,030 --> 01:01:02,799 and with our radar capability we're able 1701 01:01:08,390 --> 01:01:05,040 to image most of them 1702 01:01:10,870 --> 01:01:08,400 we have a super duper team here at jpl 1703 01:01:12,950 --> 01:01:10,880 and we are very proud of them so this 1704 01:01:14,630 --> 01:01:12,960 50th anniversary is a celebration of 1705 01:01:17,190 --> 01:01:14,640 their achievement 1706 01:01:20,069 --> 01:01:17,200 it's a something to be proud of not only 1707 01:01:21,589 --> 01:01:20,079 from a nasa perspective from uh from a 1708 01:01:23,990 --> 01:01:21,599 nation perspective 1709 01:01:26,630 --> 01:01:24,000 the united states ought to be proud of 1710 01:01:28,549 --> 01:01:26,640 their dedication and their achievement 1711 01:01:30,870 --> 01:01:28,559 and we have a lot 1712 01:01:33,349 --> 01:01:30,880 to look forward to we are celebrating 1713 01:01:34,789 --> 01:01:33,359 the past 50 years but the next 50 years 1714 01:01:37,430 --> 01:01:34,799 hopefully 1715 01:01:39,589 --> 01:01:37,440 will be much better 1716 01:01:42,470 --> 01:01:39,599 there was a question do you remember 1717 01:01:45,270 --> 01:01:42,480 where uh where were you when the msl 1718 01:01:46,789 --> 01:01:45,280 landed on on mars 1719 01:01:49,990 --> 01:01:46,799 do you remember these pictures that 1720 01:01:53,109 --> 01:01:50,000 you've seen you know streaming down 1721 01:01:54,789 --> 01:01:53,119 what was missing 1722 01:01:57,430 --> 01:01:54,799 streaming video 1723 01:01:59,430 --> 01:01:57,440 we want real high definition 1724 01:02:02,230 --> 01:01:59,440 signals to be coming down from mars to 1725 01:02:05,750 --> 01:02:02,240 see it the way we are used to like now 1726 01:02:06,710 --> 01:02:05,760 in our day to day high definition tv and 1727 01:02:08,390 --> 01:02:06,720 high 1728 01:02:11,750 --> 01:02:08,400 definition everything 1729 01:02:13,430 --> 01:02:11,760 our appetite for data eight has grown 1730 01:02:16,549 --> 01:02:13,440 tremendously 1731 01:02:19,430 --> 01:02:16,559 uh and the same for nasa you know our 1732 01:02:21,349 --> 01:02:19,440 scientists want the high data rate want 1733 01:02:23,750 --> 01:02:21,359 better capabilities 1734 01:02:25,029 --> 01:02:23,760 most of our sensors 1735 01:02:26,789 --> 01:02:25,039 and 1736 01:02:29,829 --> 01:02:26,799 payload that we put on spacecraft they 1737 01:02:32,950 --> 01:02:29,839 are taking more and more bandwidth 1738 01:02:34,549 --> 01:02:32,960 the radio frequency especially now the 1739 01:02:36,470 --> 01:02:34,559 portion of it that we use is in 1740 01:02:40,630 --> 01:02:36,480 contention 1741 01:02:42,789 --> 01:02:40,640 you know like the seller phone that you 1742 01:02:44,549 --> 01:02:42,799 have these they do use 1743 01:02:46,710 --> 01:02:44,559 portion of the spectrum 1744 01:02:49,190 --> 01:02:46,720 so we made the decision 1745 01:02:51,270 --> 01:02:49,200 to go up in frequency 1746 01:02:52,630 --> 01:02:51,280 and going up in frequency we had to look 1747 01:02:54,230 --> 01:02:52,640 at the architecture of our 1748 01:02:57,349 --> 01:02:54,240 infrastructure 1749 01:02:59,750 --> 01:02:57,359 and we've decided that the 70 meters 1750 01:03:01,589 --> 01:02:59,760 served us for a long time they are not 1751 01:03:04,069 --> 01:03:01,599 suitable to support users at high 1752 01:03:05,750 --> 01:03:04,079 frequencies so we are trying to build 1753 01:03:08,150 --> 01:03:05,760 equivalent 1754 01:03:10,390 --> 01:03:08,160 you know set of antennas 1755 01:03:12,390 --> 01:03:10,400 that are comparable in terms of 1756 01:03:13,430 --> 01:03:12,400 performance in meeting the 1757 01:03:17,029 --> 01:03:13,440 present 1758 01:03:19,430 --> 01:03:17,039 commitment to our customers but 1759 01:03:21,430 --> 01:03:19,440 allow us to go higher up in frequency 1760 01:03:22,870 --> 01:03:21,440 and support a new generation 1761 01:03:25,109 --> 01:03:22,880 of missions 1762 01:03:26,630 --> 01:03:25,119 and this is ongoing 1763 01:03:29,750 --> 01:03:26,640 this uh 1764 01:03:33,109 --> 01:03:29,760 this september we are going to celebrate 1765 01:03:34,630 --> 01:03:33,119 uh the uh introduction to operation of 1766 01:03:35,589 --> 01:03:34,640 one of the first antennas we are 1767 01:03:37,750 --> 01:03:35,599 building 1768 01:03:40,390 --> 01:03:37,760 we are also forging ahead 1769 01:03:42,630 --> 01:03:40,400 with optical communications 1770 01:03:44,950 --> 01:03:42,640 you know communicating through light 1771 01:03:47,190 --> 01:03:44,960 we at nasa have seen the light 1772 01:03:48,950 --> 01:03:47,200 and the light is wonderful you know just 1773 01:03:49,990 --> 01:03:48,960 it allows you to do so many wonderful 1774 01:03:51,349 --> 01:03:50,000 things 1775 01:03:59,510 --> 01:03:51,359 and 1776 01:04:01,109 --> 01:03:59,520 infinite compared to what we have today 1777 01:04:04,390 --> 01:04:01,119 so we are 1778 01:04:06,549 --> 01:04:04,400 we started by building the technology 1779 01:04:08,789 --> 01:04:06,559 and we recently demo uh demo this 1780 01:04:11,349 --> 01:04:08,799 technology we had a payload 1781 01:04:14,549 --> 01:04:11,359 on board the mission to the to the moon 1782 01:04:16,390 --> 01:04:14,559 you all heard about lady and the lrcd 1783 01:04:18,069 --> 01:04:16,400 and the support we provided from the 1784 01:04:21,270 --> 01:04:18,079 moon down to earth 1785 01:04:24,870 --> 01:04:21,280 622 megabit per second 1786 01:04:26,390 --> 01:04:24,880 you know at a distance 10 times that of 1787 01:04:29,190 --> 01:04:26,400 you know the distance from here to a 1788 01:04:31,029 --> 01:04:29,200 geosynchronous satellite so if you 1789 01:04:34,230 --> 01:04:31,039 translate that into 1790 01:04:35,510 --> 01:04:34,240 you know the distance into a data rate 1791 01:04:37,829 --> 01:04:35,520 uh 1792 01:04:40,390 --> 01:04:37,839 mapping you'll be able to get 1793 01:04:42,390 --> 01:04:40,400 tens of gigabits per second from a 1794 01:04:44,390 --> 01:04:42,400 geosynchronous orbit 1795 01:04:47,430 --> 01:04:44,400 from a deep space we are looking at 1796 01:04:49,109 --> 01:04:47,440 building much wider aperture because as 1797 01:04:50,309 --> 01:04:49,119 you go further 1798 01:04:52,470 --> 01:04:50,319 you know 1799 01:04:54,630 --> 01:04:52,480 you need a bigger and bigger ear or 1800 01:04:56,230 --> 01:04:54,640 bigger eye to see the light 1801 01:04:57,990 --> 01:04:56,240 and that's what we are working working 1802 01:05:00,950 --> 01:04:58,000 on much bigger 1803 01:05:03,510 --> 01:05:00,960 telescopes that will allow us to support 1804 01:05:05,109 --> 01:05:03,520 deep space missions in addition to that 1805 01:05:08,230 --> 01:05:05,119 because of the competence of the 1806 01:05:10,390 --> 01:05:08,240 technical team that we have in here we 1807 01:05:13,829 --> 01:05:10,400 have entrusted jpl 1808 01:05:17,430 --> 01:05:13,839 to build our future integrated network 1809 01:05:19,430 --> 01:05:17,440 the dsn is one single network among many 1810 01:05:22,549 --> 01:05:19,440 we have the nearest network 1811 01:05:24,549 --> 01:05:22,559 the data relay satellite network and all 1812 01:05:25,510 --> 01:05:24,559 together we support over 100 missions a 1813 01:05:28,470 --> 01:05:25,520 day 1814 01:05:30,470 --> 01:05:28,480 we transmit through our system a tera 1815 01:05:32,069 --> 01:05:30,480 byte every day there are actually 1816 01:05:34,230 --> 01:05:32,079 hundreds of terabytes 1817 01:05:36,630 --> 01:05:34,240 you know an entire library of congress 1818 01:05:37,589 --> 01:05:36,640 on a daily basis so we manage a lot of 1819 01:05:39,589 --> 01:05:37,599 data 1820 01:05:42,230 --> 01:05:39,599 but because of the technical competence 1821 01:05:44,630 --> 01:05:42,240 and competence we have in here and 1822 01:05:46,789 --> 01:05:44,640 much of the changes will occur is 1823 01:05:49,029 --> 01:05:46,799 you know in the dsn 1824 01:05:51,750 --> 01:05:49,039 hardware and software so they have been 1825 01:05:53,270 --> 01:05:51,760 entrusted to lead the nasa team toward a 1826 01:05:54,309 --> 01:05:53,280 fully integrated network that will 1827 01:05:55,270 --> 01:05:54,319 provide 1828 01:05:57,190 --> 01:05:55,280 you know 1829 01:05:59,910 --> 01:05:57,200 at least two order magnitude better 1830 01:06:02,390 --> 01:05:59,920 performance that we have today 1831 01:06:04,950 --> 01:06:02,400 i don't know how many uh met with me in 1832 01:06:06,549 --> 01:06:04,960 the past in a similar setting and i 1833 01:06:10,789 --> 01:06:06,559 promised we'll have 1834 01:06:13,829 --> 01:06:10,799 streaming video from march by 2025. 1835 01:06:15,349 --> 01:06:13,839 i still mean it i intend to do it 1836 01:06:17,670 --> 01:06:15,359 and definitely with the dedication of 1837 01:06:20,150 --> 01:06:17,680 the team here at jpl we realize that 1838 01:06:21,190 --> 01:06:20,160 pretty soon even sooner than 2025 that's 1839 01:06:22,950 --> 01:06:21,200 a promise 1840 01:06:25,670 --> 01:06:22,960 that's great and i'm hoping for any 1841 01:06:26,549 --> 01:06:25,680 questions that you may have 1842 01:06:29,109 --> 01:06:26,559 go ahead 1843 01:06:32,950 --> 01:06:29,119 let me hand you a microphone alice can 1844 01:06:35,589 --> 01:06:32,960 you get there fast yeah we'll toss them 1845 01:06:39,829 --> 01:06:35,599 um let's see i was wondering if um you 1846 01:06:44,470 --> 01:06:41,750 antenna is not suitable for the higher 1847 01:06:45,430 --> 01:06:44,480 frequencies oh why is that yeah as you 1848 01:06:48,150 --> 01:06:45,440 see 1849 01:06:50,309 --> 01:06:48,160 as you go up in frequency the 1850 01:06:52,069 --> 01:06:50,319 wavelengths start to get smaller and 1851 01:06:52,870 --> 01:06:52,079 smaller and smaller 1852 01:06:54,950 --> 01:06:52,880 then 1853 01:06:57,270 --> 01:06:54,960 the panels the lining of the panel on 1854 01:06:59,990 --> 01:06:57,280 the surface of the antenna if they are 1855 01:07:02,470 --> 01:07:00,000 not lined perfectly it can eat up from 1856 01:07:05,190 --> 01:07:02,480 the efficiency of the antenna so the 1857 01:07:07,990 --> 01:07:05,200 antenna can become less efficient 1858 01:07:10,309 --> 01:07:08,000 at high frequency especially with big 1859 01:07:13,190 --> 01:07:10,319 mechanical structures subject to you 1860 01:07:15,750 --> 01:07:13,200 know a higher wind wind load and was 1861 01:07:19,029 --> 01:07:15,760 designed early on you know that the 1862 01:07:21,829 --> 01:07:19,039 metal has started to show some fatigue 1863 01:07:24,630 --> 01:07:21,839 and it's not you know in a robust state 1864 01:07:25,349 --> 01:07:24,640 as when it was first introduced 1865 01:07:27,270 --> 01:07:25,359 uh 1866 01:07:29,190 --> 01:07:27,280 you know additionally we made a lot of 1867 01:07:30,789 --> 01:07:29,200 progress in iran 1868 01:07:34,150 --> 01:07:30,799 technology we can take a bunch of 1869 01:07:36,549 --> 01:07:34,160 smaller antennas and array them together 1870 01:07:37,670 --> 01:07:36,559 and in a way we resolve 1871 01:07:41,109 --> 01:07:37,680 the phase 1872 01:07:43,589 --> 01:07:41,119 between 1873 01:07:45,829 --> 01:07:43,599 the various antennas such that when we 1874 01:07:47,829 --> 01:07:45,839 put the you know collect the signal from 1875 01:07:49,829 --> 01:07:47,839 all of them will have a coherent 1876 01:07:51,750 --> 01:07:49,839 you know uh signal 1877 01:07:53,349 --> 01:07:51,760 thank you all right thank you so much 1878 01:07:55,829 --> 01:07:53,359 for coming in today i know you'll be out 1879 01:07:57,670 --> 01:07:55,839 at goldstone tomorrow by the way 1880 01:08:00,230 --> 01:07:57,680 tomorrow is going to be a wonderful day 1881 01:08:03,270 --> 01:08:00,240 we arranged it for you you know wayne 1882 01:08:04,390 --> 01:08:03,280 assures me and we have confirmation from 1883 01:08:07,029 --> 01:08:04,400 the weather 1884 01:08:09,109 --> 01:08:07,039 you know a person that tomorrow is going 1885 01:08:11,349 --> 01:08:09,119 to be a wonderful day and you are going 1886 01:08:13,589 --> 01:08:11,359 to enjoy you know talking about it is 1887 01:08:15,670 --> 01:08:13,599 different you know seeing is believing 1888 01:08:17,269 --> 01:08:15,680 you are going to see the 70 meter you 1889 01:08:19,749 --> 01:08:17,279 are going to see some of these engine 1890 01:08:21,749 --> 01:08:19,759 engineers running around doing some of 1891 01:08:23,749 --> 01:08:21,759 what they do best and these are the 1892 01:08:25,749 --> 01:08:23,759 people who are behind the curtain you 1893 01:08:26,950 --> 01:08:25,759 know when the msl landed 1894 01:08:28,630 --> 01:08:26,960 they were the first to know but they 1895 01:08:30,789 --> 01:08:28,640 were not authorized to the to make that 1896 01:08:34,070 --> 01:08:30,799 declaration 1897 01:08:35,829 --> 01:08:34,080 you know we but the navigators and the 1898 01:08:37,669 --> 01:08:35,839 calm people in here 1899 01:08:39,590 --> 01:08:37,679 are the kind of people that we ought all 1900 01:08:43,269 --> 01:08:39,600 to be proud of 1901 01:08:44,070 --> 01:08:43,279 and give them their recognition you know 1902 01:08:47,430 --> 01:08:44,080 very 1903 01:08:49,829 --> 01:08:47,440 londo or you know 1904 01:08:51,669 --> 01:08:49,839 recognition for all of the work they do 1905 01:08:53,349 --> 01:08:51,679 they are an enabling entity within the 1906 01:08:55,189 --> 01:08:53,359 agency without which 1907 01:08:57,349 --> 01:08:55,199 none of the discoveries none of this 1908 01:08:59,110 --> 01:08:57,359 science could have taken place 1909 01:09:03,110 --> 01:08:59,120 absolutely 1910 01:09:07,269 --> 01:09:04,870 that's so true they do they really do 1911 01:09:09,110 --> 01:09:07,279 work completely behind the scenes uh so 1912 01:09:10,470 --> 01:09:09,120 now um we're gonna have our final panel 1913 01:09:12,470 --> 01:09:10,480 for the day and and you've heard from 1914 01:09:13,910 --> 01:09:12,480 the engineers about how crucial it is 1915 01:09:15,590 --> 01:09:13,920 for the deep space network for them to 1916 01:09:17,430 --> 01:09:15,600 know where their spacecraft is and if 1917 01:09:18,550 --> 01:09:17,440 they're landing safely and now we want 1918 01:09:20,470 --> 01:09:18,560 to introduce you to some of the 1919 01:09:22,550 --> 01:09:20,480 scientists that then sit back and wait 1920 01:09:24,630 --> 01:09:22,560 for their science data and images to 1921 01:09:26,550 --> 01:09:24,640 come back to earth and how they use 1922 01:09:29,269 --> 01:09:26,560 those and so joining us 1923 01:09:31,990 --> 01:09:29,279 we have ashwin vasavada he is the deputy 1924 01:09:35,349 --> 01:09:32,000 project scientist for curiosity 1925 01:09:36,550 --> 01:09:35,359 and that's fine marina brasovich marina 1926 01:09:39,349 --> 01:09:36,560 is a 1927 01:09:42,149 --> 01:09:39,359 scientist with our near uh earth objects 1928 01:09:43,510 --> 01:09:42,159 office and uh uses the dsn to study 1929 01:09:45,510 --> 01:09:43,520 asteroids 1930 01:09:46,950 --> 01:09:45,520 and linda spelker who is the project 1931 01:09:50,149 --> 01:09:46,960 scientist for the cassini mission which 1932 01:09:57,350 --> 01:09:50,159 has been orbiting saturn since 2004 and 1933 01:10:00,950 --> 01:09:59,430 take it away all right excellent hey 1934 01:10:02,790 --> 01:10:00,960 how's everybody doing 1935 01:10:05,110 --> 01:10:02,800 all right you can talk to scientists but 1936 01:10:06,950 --> 01:10:05,120 we're not going to bore you i promise 1937 01:10:08,470 --> 01:10:06,960 we got great stuff to talk to you about 1938 01:10:09,750 --> 01:10:08,480 especially how it's all been enabled by 1939 01:10:10,870 --> 01:10:09,760 the dsn 1940 01:10:12,950 --> 01:10:10,880 i've been 1941 01:10:14,709 --> 01:10:12,960 a planetary scientist for um i don't 1942 01:10:16,950 --> 01:10:14,719 know about 20 years now and 10 years of 1943 01:10:19,590 --> 01:10:16,960 that has all been on curiosity it's been 1944 01:10:21,030 --> 01:10:19,600 a long road uh but it's paid off 1945 01:10:23,430 --> 01:10:21,040 immensely and we'll talk about some of 1946 01:10:24,709 --> 01:10:23,440 that um i think i was thinking about 1947 01:10:27,030 --> 01:10:24,719 what you know what i could share about 1948 01:10:28,950 --> 01:10:27,040 the dsm i think there was two moments 1949 01:10:30,870 --> 01:10:28,960 in my life 1950 01:10:32,390 --> 01:10:30,880 in planetary science that i really felt 1951 01:10:33,830 --> 01:10:32,400 like i was exploring 1952 01:10:35,590 --> 01:10:33,840 deep space 1953 01:10:37,830 --> 01:10:35,600 you know a lot of what i do is staring 1954 01:10:39,110 --> 01:10:37,840 at a computer and i see pictures come up 1955 01:10:40,630 --> 01:10:39,120 and it can feel you can kind of get 1956 01:10:42,310 --> 01:10:40,640 disconnected you forget that you're 1957 01:10:44,390 --> 01:10:42,320 actually doing something on another 1958 01:10:46,550 --> 01:10:44,400 planet and one of those experiences was 1959 01:10:48,229 --> 01:10:46,560 the launch of curiosity i know it's like 1960 01:10:50,149 --> 01:10:48,239 sacrilegious but the landing wasn't my 1961 01:10:51,750 --> 01:10:50,159 favorite part it was actually the launch 1962 01:10:53,350 --> 01:10:51,760 and i was standing there in florida 1963 01:10:55,189 --> 01:10:53,360 watching this rocket go up and hearing 1964 01:10:57,430 --> 01:10:55,199 the noise and seeing this huge you know 1965 01:10:59,110 --> 01:10:57,440 multi-story thing go up and thinking 1966 01:11:00,709 --> 01:10:59,120 okay you know we are actually human 1967 01:11:02,070 --> 01:11:00,719 beings just throwing something off of 1968 01:11:04,149 --> 01:11:02,080 our planet to another planet and it 1969 01:11:05,750 --> 01:11:04,159 takes that much energy to do that and 1970 01:11:08,149 --> 01:11:05,760 that much force and it was it was an 1971 01:11:10,310 --> 01:11:08,159 amazing kind of visceral moment 1972 01:11:12,470 --> 01:11:10,320 the other time was um really early when 1973 01:11:13,590 --> 01:11:12,480 i was in grad school and i went on a 1974 01:11:15,270 --> 01:11:13,600 field trip just like the one you're 1975 01:11:17,830 --> 01:11:15,280 going to go on tomorrow and got to stick 1976 01:11:20,310 --> 01:11:17,840 my head up into the 70 meter dish and 1977 01:11:22,310 --> 01:11:20,320 see what it takes to just even 1978 01:11:24,709 --> 01:11:22,320 send little ones and zeros to something 1979 01:11:26,550 --> 01:11:24,719 so far away and to think that you know 1980 01:11:28,229 --> 01:11:26,560 robots out there you know hundreds of 1981 01:11:30,709 --> 01:11:28,239 millions of miles away are receiving our 1982 01:11:32,709 --> 01:11:30,719 signals from earth that also was just a 1983 01:11:34,470 --> 01:11:32,719 mind-blowing moment to think wow we're 1984 01:11:36,550 --> 01:11:34,480 doing something pretty amazing and all 1985 01:11:38,550 --> 01:11:36,560 enabled by the dsn 1986 01:11:41,350 --> 01:11:38,560 um i'll show you one 1987 01:11:43,350 --> 01:11:41,360 picture which uh choosing of the 1988 01:11:45,990 --> 01:11:43,360 thousands and thousands of pictures that 1989 01:11:47,189 --> 01:11:46,000 we've gotten back from curiosity 1990 01:11:49,990 --> 01:11:47,199 turn your attention to this one over 1991 01:11:51,910 --> 01:11:50,000 here this was just from last week we 1992 01:11:54,390 --> 01:11:51,920 rolled up to a site called the kimberly 1993 01:11:56,550 --> 01:11:54,400 which is named after a geological region 1994 01:11:58,470 --> 01:11:56,560 in northern australia we tend to name 1995 01:11:59,990 --> 01:11:58,480 all of our sites on curiosity after 1996 01:12:02,709 --> 01:12:00,000 famous geological 1997 01:12:04,390 --> 01:12:02,719 formations on earth this site like we've 1998 01:12:07,910 --> 01:12:04,400 been finding all over the crater floor 1999 01:12:10,630 --> 01:12:07,920 around mount sharp is a place where a 2000 01:12:12,550 --> 01:12:10,640 river once flowed and water pooled maybe 2001 01:12:14,870 --> 01:12:12,560 in lakes or maybe a whole series of 2002 01:12:16,790 --> 01:12:14,880 lakes laying down what you see here is 2003 01:12:18,870 --> 01:12:16,800 finely bedded sandstones these 2004 01:12:21,110 --> 01:12:18,880 sandstones have grain sizes that are are 2005 01:12:23,590 --> 01:12:21,120 like beach sand and then all the way up 2006 01:12:25,669 --> 01:12:23,600 to things like pebbles and gravel 2007 01:12:27,750 --> 01:12:25,679 and that tends to mean that water flowed 2008 01:12:29,990 --> 01:12:27,760 at different rates um slower water 2009 01:12:32,470 --> 01:12:30,000 carrying the smaller particles more fast 2010 01:12:33,669 --> 01:12:32,480 water carrying the the gravel and things 2011 01:12:35,990 --> 01:12:33,679 have kind of come and gone maybe 2012 01:12:37,910 --> 01:12:36,000 shorelines have come and gone maybe uh 2013 01:12:40,470 --> 01:12:37,920 rivers emptied out into lakes that that 2014 01:12:42,470 --> 01:12:40,480 came and went and it's just amazing to 2015 01:12:44,229 --> 01:12:42,480 think that a few billion years ago mars 2016 01:12:46,229 --> 01:12:44,239 was so earth-like and that's what we're 2017 01:12:49,750 --> 01:12:46,239 really finding about uh with with 2018 01:12:51,910 --> 01:12:49,760 curiosity that uh this planet uh was a 2019 01:12:54,630 --> 01:12:51,920 place where rain probably fell from the 2020 01:12:57,110 --> 01:12:54,640 sky and and streams formed rivers and 2021 01:12:59,030 --> 01:12:57,120 rivers carried sand deposited them into 2022 01:13:00,390 --> 01:12:59,040 lakes all around this gorgeous mountain 2023 01:13:01,189 --> 01:13:00,400 that will be climbing in the next couple 2024 01:13:03,990 --> 01:13:01,199 years 2025 01:13:05,910 --> 01:13:04,000 so with that i'll turn it over to marina 2026 01:13:08,390 --> 01:13:05,920 thanks 2027 01:13:11,270 --> 01:13:08,400 hi everybody so um i'll be talking a 2028 01:13:13,910 --> 01:13:11,280 little bit how we use a dsn 70 meter 2029 01:13:17,030 --> 01:13:13,920 antenna so uh probably not many of you 2030 01:13:18,310 --> 01:13:17,040 know that 70 meter antenna the ss14 2031 01:13:20,229 --> 01:13:18,320 actually is equipped with a very 2032 01:13:21,910 --> 01:13:20,239 powerful transmitter it has a half a 2033 01:13:24,229 --> 01:13:21,920 megawatt transmitter 2034 01:13:26,709 --> 01:13:24,239 and it is the second it's world's second 2035 01:13:29,510 --> 01:13:26,719 most powerful radar right after our sibo 2036 01:13:32,550 --> 01:13:29,520 in puerto rico and what we use for we 2037 01:13:35,189 --> 01:13:32,560 use dss-14 to ping asteroids 2038 01:13:37,189 --> 01:13:35,199 and to learn about their exact locations 2039 01:13:39,669 --> 01:13:37,199 and line of sight velocities and that 2040 01:13:42,149 --> 01:13:39,679 allows us to calculate their orbits much 2041 01:13:43,990 --> 01:13:42,159 more precisely and then we also use it 2042 01:13:45,830 --> 01:13:44,000 to image asteroids 2043 01:13:49,350 --> 01:13:45,840 at dss14 we 2044 01:13:50,229 --> 01:13:49,360 observe about 25 to 30 asteroids every 2045 01:13:52,310 --> 01:13:50,239 year 2046 01:13:53,830 --> 01:13:52,320 and in some instances some of these 2047 01:13:55,189 --> 01:13:53,840 asteroids end up being really strong 2048 01:13:58,550 --> 01:13:55,199 radar targets 2049 01:14:00,630 --> 01:13:58,560 and the images that we get from them are 2050 01:14:03,590 --> 01:14:00,640 such a high quality that it can only be 2051 01:14:05,189 --> 01:14:03,600 compared to spacecraft flyby 2052 01:14:07,350 --> 01:14:05,199 so what i'm going to show you now is 2053 01:14:09,350 --> 01:14:07,360 example of something that we consider 2054 01:14:11,750 --> 01:14:09,360 spacecraft flyby and that is asteroid to 2055 01:14:13,590 --> 01:14:11,760 titus uh if we can have the video please 2056 01:14:14,870 --> 01:14:13,600 so this is what this is the asteroid 2057 01:14:17,590 --> 01:14:14,880 that we imaged 2058 01:14:19,350 --> 01:14:17,600 in december of 2012 2059 01:14:21,430 --> 01:14:19,360 uh these are radar images you'll notice 2060 01:14:23,669 --> 01:14:21,440 these are very different from the images 2061 01:14:26,149 --> 01:14:23,679 that you would take with your camera 2062 01:14:27,830 --> 01:14:26,159 because what what so radar images where 2063 01:14:29,669 --> 01:14:27,840 they're displaying on vertical axis 2064 01:14:32,470 --> 01:14:29,679 they're displaying the distance from the 2065 01:14:34,310 --> 01:14:32,480 radar so this is the depth if you will 2066 01:14:36,950 --> 01:14:34,320 and then on the horizontal axis what 2067 01:14:39,669 --> 01:14:36,960 you're seeing is how fast the parts of 2068 01:14:41,910 --> 01:14:39,679 the asteroid are moving toward the radar 2069 01:14:44,229 --> 01:14:41,920 away from radar and i know this is not 2070 01:14:46,149 --> 01:14:44,239 very intuitive but still if you look at 2071 01:14:48,070 --> 01:14:46,159 these videos 2072 01:14:50,470 --> 01:14:48,080 you know some things are obvious so 2073 01:14:52,229 --> 01:14:50,480 these two videos are taken these two 2074 01:14:54,310 --> 01:14:52,239 they are taken on two different days 2075 01:14:56,149 --> 01:14:54,320 that's why the radar echoes looks look 2076 01:14:59,110 --> 01:14:56,159 so different because the asteroid is 2077 01:15:01,350 --> 01:14:59,120 rotated is oriented differently in space 2078 01:15:04,310 --> 01:15:01,360 with respect to radar on the two days 2079 01:15:05,830 --> 01:15:04,320 and another obvious thing is that 2080 01:15:07,750 --> 01:15:05,840 when you image it with a radar for a 2081 01:15:09,750 --> 01:15:07,760 couple of hours you see it's rotating 2082 01:15:11,830 --> 01:15:09,760 the asteroid is actually rotating in 2083 01:15:12,870 --> 01:15:11,840 front of your eyes 2084 01:15:15,189 --> 01:15:12,880 and 2085 01:15:17,510 --> 01:15:15,199 the resolution the pixel vertical pixel 2086 01:15:18,310 --> 01:15:17,520 resolution on these images is only 12 2087 01:15:20,070 --> 01:15:18,320 feet 2088 01:15:23,270 --> 01:15:20,080 which is really impressive considering 2089 01:15:25,990 --> 01:15:23,280 this asteroid is 4.3 million miles away 2090 01:15:28,630 --> 01:15:26,000 from us and we are imaging it down to 12 2091 01:15:30,470 --> 01:15:28,640 feet and what this resolution is really 2092 01:15:32,149 --> 01:15:30,480 allowing you is you even see the 2093 01:15:34,310 --> 01:15:32,159 boulders that are lying on the surface 2094 01:15:36,870 --> 01:15:34,320 of asteroid and those little bright 2095 01:15:39,110 --> 01:15:36,880 specks that know to come in in you can 2096 01:15:41,189 --> 01:15:39,120 see them as the asteroid is rotating and 2097 01:15:43,430 --> 01:15:41,199 they persist those are actually the 2098 01:15:46,550 --> 01:15:43,440 boulders on the surface of asteroid that 2099 01:15:48,470 --> 01:15:46,560 is 4.3 million miles away 2100 01:15:51,030 --> 01:15:48,480 what we ultimately do with images like 2101 01:15:52,550 --> 01:15:51,040 this is we reconstructed how the object 2102 01:15:54,390 --> 01:15:52,560 how the asteroid really looks in 2103 01:15:57,030 --> 01:15:54,400 three-dimensional space 2104 01:15:59,270 --> 01:15:57,040 so uh we also reconstruct how it rotates 2105 01:16:01,510 --> 01:15:59,280 and this asteroid to tardis i'm showing 2106 01:16:04,149 --> 01:16:01,520 you here this is reconstruction of its 2107 01:16:05,990 --> 01:16:04,159 three-dimensional uh shape based on 2108 01:16:07,830 --> 01:16:06,000 radar images that we're taking actually 2109 01:16:10,229 --> 01:16:07,840 prior they're all these are older based 2110 01:16:13,870 --> 01:16:10,239 on all the radar data but it is very 2111 01:16:15,990 --> 01:16:13,880 very unusual asteroid um this is about 2112 01:16:17,350 --> 01:16:16,000 2.9 miles 2113 01:16:19,590 --> 01:16:17,360 long 2114 01:16:22,310 --> 01:16:19,600 it has this regular shape it looks like 2115 01:16:23,430 --> 01:16:22,320 these kind of two pieces in contact this 2116 01:16:25,110 --> 01:16:23,440 is something that we actually call 2117 01:16:27,350 --> 01:16:25,120 contact binaries 2118 01:16:30,310 --> 01:16:27,360 and even its rotation state is kind of 2119 01:16:33,510 --> 01:16:30,320 unusual because it it kind of rotates 2120 01:16:36,149 --> 01:16:33,520 like a poorly thrown football so it's 2121 01:16:38,310 --> 01:16:36,159 it's rotation around long axis is 5.4 2122 01:16:40,390 --> 01:16:38,320 days and at the same time it's executing 2123 01:16:42,070 --> 01:16:40,400 this precession with seven four in four 2124 01:16:44,470 --> 01:16:42,080 days so it kind of is it's really 2125 01:16:46,550 --> 01:16:44,480 tumbling it's tumbling through space 2126 01:16:48,310 --> 01:16:46,560 and this is not the 2127 01:16:50,070 --> 01:16:48,320 this is not the only one that we have 2128 01:16:52,550 --> 01:16:50,080 you know shape models of these are some 2129 01:16:54,790 --> 01:16:52,560 other examples you know for asteroids 2130 01:16:56,870 --> 01:16:54,800 that um we reconstructed their shape 2131 01:16:59,750 --> 01:16:56,880 based on the radar data so there is a 2132 01:17:01,910 --> 01:16:59,760 binary kw-4 there is this regularly 2133 01:17:05,270 --> 01:17:01,920 shaped asteroid called europe there's 2134 01:17:07,590 --> 01:17:05,280 another contact binary hw1 and then 2135 01:17:10,630 --> 01:17:07,600 there is the nereus as you can see this 2136 01:17:13,189 --> 01:17:10,640 is a we really see tremendous diversity 2137 01:17:16,630 --> 01:17:13,199 in near-earth asteroids among near-earth 2138 01:17:18,950 --> 01:17:16,640 asteroids every time we observe uh we 2139 01:17:20,950 --> 01:17:18,960 really are going in a completely kind of 2140 01:17:22,870 --> 01:17:20,960 we we usually know very little about 2141 01:17:24,470 --> 01:17:22,880 asteroid we'll be observing 2142 01:17:25,990 --> 01:17:24,480 and um 2143 01:17:28,470 --> 01:17:26,000 we you never know what you're going to 2144 01:17:31,430 --> 01:17:28,480 see and and the best thing in a life of 2145 01:17:33,990 --> 01:17:31,440 scientists is to be you know surprised 2146 01:17:36,149 --> 01:17:34,000 and we never cease to find you know we 2147 01:17:38,229 --> 01:17:36,159 always end up being surprised 2148 01:17:40,149 --> 01:17:38,239 because there is so much more things to 2149 01:17:43,030 --> 01:17:40,159 discover 2150 01:17:44,950 --> 01:17:43,040 so um thank you 2151 01:17:47,590 --> 01:17:44,960 okay i'm linda spilker and i've been 2152 01:17:48,550 --> 01:17:47,600 fortunate enough to work at jpl for 37 2153 01:17:50,470 --> 01:17:48,560 years 2154 01:17:52,790 --> 01:17:50,480 and that spans from just before the 2155 01:17:54,310 --> 01:17:52,800 launch of voyager through the cassini 2156 01:17:56,709 --> 01:17:54,320 mission and so i'm going to talk a 2157 01:17:58,070 --> 01:17:56,719 little bit about both of those missions 2158 01:18:00,630 --> 01:17:58,080 if you think about it voyager was 2159 01:18:02,870 --> 01:18:00,640 launched about 36 years ago two voyager 2160 01:18:05,030 --> 01:18:02,880 spacecraft and that's about three 2161 01:18:07,030 --> 01:18:05,040 quarters of this 50th anniversary we're 2162 01:18:08,790 --> 01:18:07,040 celebrating with the dsn 2163 01:18:10,229 --> 01:18:08,800 so the dsn has been listening to voyager 2164 01:18:12,630 --> 01:18:10,239 for a long time 2165 01:18:15,270 --> 01:18:12,640 there have been great flybys of jupiter 2166 01:18:17,830 --> 01:18:15,280 saturn uranus and neptune and their 2167 01:18:19,990 --> 01:18:17,840 incredible moons and rings and for me a 2168 01:18:22,149 --> 01:18:20,000 really exciting moment in just watching 2169 01:18:24,310 --> 01:18:22,159 those pictures come back from voyager 2170 01:18:28,310 --> 01:18:24,320 was actually realizing that there were 2171 01:18:31,189 --> 01:18:28,320 volcanoes on jupiter's moon io volcanoes 2172 01:18:33,510 --> 01:18:31,199 going off as we were watching those data 2173 01:18:35,430 --> 01:18:33,520 and just incredible what those ones and 2174 01:18:37,990 --> 01:18:35,440 zeroes can turn into 2175 01:18:40,630 --> 01:18:38,000 these very beautiful color images and it 2176 01:18:44,310 --> 01:18:40,640 turns out that voyager 1 in august of 2177 01:18:46,790 --> 01:18:44,320 2012 if we bring up the first video here 2178 01:18:48,390 --> 01:18:46,800 actually left our solar system and is in 2179 01:18:50,149 --> 01:18:48,400 interstellar space 2180 01:18:51,830 --> 01:18:50,159 here are the sounds first just before 2181 01:18:54,229 --> 01:18:51,840 interstellar space 2182 01:18:57,430 --> 01:18:54,239 the frequency goes up as the plasma 2183 01:18:58,790 --> 01:18:57,440 density increases until you hear a very 2184 01:19:00,790 --> 01:18:58,800 high tone 2185 01:19:03,590 --> 01:19:00,800 you're hearing what the wind between the 2186 01:19:05,750 --> 01:19:03,600 stars would sound like coming back from 2187 01:19:07,110 --> 01:19:05,760 voyager and there's a plasma wave 2188 01:19:09,430 --> 01:19:07,120 spectrometer 2189 01:19:12,470 --> 01:19:09,440 that recorded those data 2190 01:19:14,950 --> 01:19:12,480 now cassini was launched 17 years ago so 2191 01:19:16,709 --> 01:19:14,960 that's about one-third of the the 50 2192 01:19:18,790 --> 01:19:16,719 years from the dsn 2193 01:19:21,750 --> 01:19:18,800 and cassini has been sending back data 2194 01:19:23,910 --> 01:19:21,760 continuously and and for me probably the 2195 01:19:26,550 --> 01:19:23,920 one of the biggest most interesting 2196 01:19:28,950 --> 01:19:26,560 discoveries for cassini was actually 2197 01:19:31,590 --> 01:19:28,960 seeing this tiny moon enceladus 2198 01:19:34,870 --> 01:19:31,600 it's 300 miles across you could fit it 2199 01:19:37,030 --> 01:19:34,880 between los angeles and san francisco 2200 01:19:40,229 --> 01:19:37,040 and yet coming out of cracks at its 2201 01:19:42,870 --> 01:19:40,239 south pole were these jets of salt water 2202 01:19:45,510 --> 01:19:42,880 coming out and going out into space and 2203 01:19:47,350 --> 01:19:45,520 creating a very beautiful ring the 2204 01:19:48,229 --> 01:19:47,360 e-ring in fact if you look at the next 2205 01:19:50,229 --> 01:19:48,239 image 2206 01:19:52,310 --> 01:19:50,239 this is one of my very favorite pictures 2207 01:19:55,590 --> 01:19:52,320 it was taken last july 2208 01:19:57,430 --> 01:19:55,600 it's made up of 141 images and that very 2209 01:20:00,229 --> 01:19:57,440 outermost blue ring 2210 01:20:03,830 --> 01:20:00,239 that's the e-ring being supplied by the 2211 01:20:05,830 --> 01:20:03,840 water jets coming from tiny enceladus 2212 01:20:08,470 --> 01:20:05,840 and you'll notice there's a bright ring 2213 01:20:10,709 --> 01:20:08,480 around the outermost limb of saturn and 2214 01:20:14,149 --> 01:20:10,719 if you think about it that's every 2215 01:20:16,470 --> 01:20:14,159 sunrise and every sunset on saturn that 2216 01:20:18,470 --> 01:20:16,480 we can see at the same time 2217 01:20:20,070 --> 01:20:18,480 also in this image you have mars and 2218 01:20:22,790 --> 01:20:20,080 venus and the earth so you have four 2219 01:20:25,189 --> 01:20:22,800 planets in this particular mosaic and on 2220 01:20:26,709 --> 01:20:25,199 that day in july we asked everyone to 2221 01:20:29,270 --> 01:20:26,719 wave at saturn 2222 01:20:31,110 --> 01:20:29,280 while cassini was taking those pictures 2223 01:20:32,950 --> 01:20:31,120 and so there are little photons that had 2224 01:20:35,110 --> 01:20:32,960 come into the cassini cameras of all of 2225 01:20:37,669 --> 01:20:35,120 those people from around around the 2226 01:20:39,350 --> 01:20:37,679 world waving at saturn 2227 01:20:41,590 --> 01:20:39,360 and of course you can't do any of this 2228 01:20:43,350 --> 01:20:41,600 without the data from the dsn so it's 2229 01:20:45,189 --> 01:20:43,360 really pivotal in 2230 01:20:47,030 --> 01:20:45,199 getting our understanding 2231 01:20:48,950 --> 01:20:47,040 increased to actually have those data 2232 01:20:50,709 --> 01:20:48,960 come back and so 2233 01:20:53,830 --> 01:20:50,719 with that if there's any questions we'd 2234 01:20:58,229 --> 01:20:55,830 do we have any questions 2235 01:21:00,070 --> 01:20:58,239 okay alice we'll get to this one first 2236 01:21:01,590 --> 01:21:00,080 and then we'll go in the back there and 2237 01:21:03,430 --> 01:21:01,600 then over on this side 2238 01:21:05,270 --> 01:21:03,440 sorry it's probably an obvious question 2239 01:21:07,590 --> 01:21:05,280 based on what you said but 2240 01:21:09,270 --> 01:21:07,600 then with any of that stuff that your 2241 01:21:12,310 --> 01:21:09,280 your you all have been discussing been 2242 01:21:13,910 --> 01:21:12,320 possible without dsn 2243 01:21:15,510 --> 01:21:13,920 it would have been for the outer planet 2244 01:21:17,669 --> 01:21:15,520 missions especially if you didn't have 2245 01:21:19,030 --> 01:21:17,679 the dsn you think about what they did in 2246 01:21:21,510 --> 01:21:19,040 some of the early days where you would 2247 01:21:23,590 --> 01:21:21,520 take pictures put it on film and send 2248 01:21:25,990 --> 01:21:23,600 the film back and that certainly would 2249 01:21:29,110 --> 01:21:26,000 be a very long and tedious way so the 2250 01:21:30,390 --> 01:21:29,120 dsn is really key especially for 2251 01:21:32,950 --> 01:21:30,400 missions that are far away you know 2252 01:21:34,790 --> 01:21:32,960 voyager with one and a half days round 2253 01:21:37,830 --> 01:21:34,800 trip light time that's a long way to 2254 01:21:42,070 --> 01:21:39,990 so dss-14 is really unique instrument 2255 01:21:44,310 --> 01:21:42,080 for us there are only two planetary 2256 01:21:46,470 --> 01:21:44,320 radars in the world and this is one of 2257 01:21:47,510 --> 01:21:46,480 two so we are getting tremendous science 2258 01:21:49,270 --> 01:21:47,520 every time 2259 01:21:52,149 --> 01:21:49,280 uh you know when we observe asteroids 2260 01:21:54,629 --> 01:21:52,159 and uh definitely um 2261 01:21:56,390 --> 01:21:54,639 i really can't imagine um you know i 2262 01:21:57,990 --> 01:21:56,400 can't imagine you know kind of science 2263 01:21:59,030 --> 01:21:58,000 science productivity that we have 2264 01:22:01,910 --> 01:21:59,040 without 2265 01:22:03,510 --> 01:22:01,920 uh dss 14. 2266 01:22:06,550 --> 01:22:03,520 the only thing i'll add to that is um 2267 01:22:08,390 --> 01:22:06,560 you know it's the dsn is uh 2268 01:22:10,149 --> 01:22:08,400 it's completely enabling for curiosity 2269 01:22:11,430 --> 01:22:10,159 but we also need the orbiters the 2270 01:22:13,750 --> 01:22:11,440 amazing thing is we're building a whole 2271 01:22:15,750 --> 01:22:13,760 communications infrastructure out there 2272 01:22:18,550 --> 01:22:15,760 you know we send commands directly from 2273 01:22:19,990 --> 01:22:18,560 the dsn dishes to curiosity but that's 2274 01:22:21,830 --> 01:22:20,000 not that much data just a list of 2275 01:22:23,830 --> 01:22:21,840 instructions for the day but to get all 2276 01:22:25,270 --> 01:22:23,840 those gorgeous images back curiosity 2277 01:22:27,350 --> 01:22:25,280 first talks to the orbiters and the 2278 01:22:28,950 --> 01:22:27,360 orbiters relay at a much higher rate 2279 01:22:30,709 --> 01:22:28,960 that the dsn can 2280 01:22:33,270 --> 01:22:30,719 accept from the orbiters uh back to 2281 01:22:35,669 --> 01:22:33,280 earth so you know it's a it's a link in 2282 01:22:37,510 --> 01:22:35,679 a chain that we totally need to get all 2283 01:22:39,350 --> 01:22:37,520 these gorgeous pictures back and video 2284 01:22:40,550 --> 01:22:39,360 one day 2285 01:22:41,669 --> 01:22:40,560 okay we had a question right there on 2286 01:22:44,149 --> 01:22:41,679 the end 2287 01:22:46,070 --> 01:22:44,159 yeah hi uh marina i was wondering okay 2288 01:22:47,669 --> 01:22:46,080 you said those were replicas of the 2289 01:22:49,350 --> 01:22:47,679 asteroids 2290 01:22:50,629 --> 01:22:49,360 their reconstruction of the shapes 2291 01:22:53,430 --> 01:22:50,639 because 2292 01:22:55,510 --> 01:22:53,440 so are asteroids that smooth or are they 2293 01:22:57,669 --> 01:22:55,520 like that movie where they were all 2294 01:22:59,270 --> 01:22:57,679 rugged and dry oh well yeah we are 2295 01:23:01,669 --> 01:22:59,280 limited with the resolution of the data 2296 01:23:04,149 --> 01:23:01,679 that we have so obviously in the past 2297 01:23:07,110 --> 01:23:04,159 since 2010 we have this capability to 2298 01:23:10,870 --> 01:23:07,120 image uh two image asteroids uh with uh 2299 01:23:13,110 --> 01:23:10,880 you know 12 feet resolution so anything 2300 01:23:15,669 --> 01:23:13,120 you know these uh these models um 2301 01:23:18,390 --> 01:23:15,679 usually match the data resolution 2302 01:23:20,550 --> 01:23:18,400 and the all these are based on a 2303 01:23:22,870 --> 01:23:20,560 more coarser data not necessarily you 2304 01:23:25,750 --> 01:23:22,880 know uh fine details 2305 01:23:27,590 --> 01:23:25,760 so um so yeah it is uh 2306 01:23:30,149 --> 01:23:27,600 the asteroids are not definitely that 2307 01:23:32,709 --> 01:23:30,159 smooth we know that uh many of them have 2308 01:23:35,510 --> 01:23:32,719 these surface boulders a lot of them 2309 01:23:37,030 --> 01:23:35,520 have the concavities and and i didn't 2310 01:23:39,030 --> 01:23:37,040 bring you examples of the asteroids 2311 01:23:41,030 --> 01:23:39,040 where we actually clearly see you know 2312 01:23:43,189 --> 01:23:41,040 something like concavities and ridges 2313 01:23:45,270 --> 01:23:43,199 and hills and so there is much more 2314 01:23:47,189 --> 01:23:45,280 diversity than what i what i i just 2315 01:23:48,870 --> 01:23:47,199 picked up this was the first thing lying 2316 01:23:50,629 --> 01:23:48,880 on my desk this morning so 2317 01:23:52,310 --> 01:23:50,639 this is what you end up seeing but we 2318 01:23:54,550 --> 01:23:52,320 have many more i mean this one is pretty 2319 01:23:56,310 --> 01:23:54,560 rugged if you look this is europe and it 2320 01:23:59,110 --> 01:23:56,320 looks it's it's everything but smooth 2321 01:24:03,590 --> 01:23:59,120 this is about 120 meter object 2322 01:24:04,790 --> 01:24:03,600 and definitely a lot of structure there 2323 01:24:07,590 --> 01:24:04,800 do we have another question in the room 2324 01:24:11,510 --> 01:24:09,750 yes this is uh for marina as well as a 2325 01:24:15,990 --> 01:24:11,520 paleontologist i'm 2326 01:24:17,510 --> 01:24:16,000 really interested in asteroids um 2327 01:24:19,270 --> 01:24:17,520 mainly because you know dinosaurs went 2328 01:24:22,790 --> 01:24:19,280 bye-bye thanks to one 2329 01:24:24,790 --> 01:24:22,800 the thing i want to to know uh as well 2330 01:24:26,229 --> 01:24:24,800 as everyone watching and throughout 2331 01:24:27,910 --> 01:24:26,239 twitter and all that 2332 01:24:29,750 --> 01:24:27,920 so many people are concerned with 2333 01:24:31,910 --> 01:24:29,760 extinction-level events of asteroid 2334 01:24:34,310 --> 01:24:31,920 impacts could you please just tell us 2335 01:24:35,910 --> 01:24:34,320 the infinitesimal possibility of 2336 01:24:39,590 --> 01:24:35,920 everything lining up 2337 01:24:41,350 --> 01:24:39,600 because it's it's not that certain or 2338 01:24:44,550 --> 01:24:41,360 even 2339 01:24:46,149 --> 01:24:44,560 remotely possible it is but it's just 2340 01:24:48,550 --> 01:24:46,159 tiny little 2341 01:24:50,629 --> 01:24:48,560 window of opportunity more or less 2342 01:24:52,870 --> 01:24:50,639 well i can tell you that uh well nessa 2343 01:24:54,790 --> 01:24:52,880 is obviously nasa through its surveys is 2344 01:24:56,830 --> 01:24:54,800 keeping a very close watch 2345 01:25:00,149 --> 01:24:56,840 on on asteroids and 2346 01:25:02,870 --> 01:25:00,159 the lot of the survey of a really large 2347 01:25:03,910 --> 01:25:02,880 ones has been completed so at this point 2348 01:25:06,310 --> 01:25:03,920 we know 2349 01:25:07,990 --> 01:25:06,320 we have mapped everything that is larger 2350 01:25:10,390 --> 01:25:08,000 than one kilometer 2351 01:25:13,430 --> 01:25:10,400 um that it we we mapped it at the order 2352 01:25:15,590 --> 01:25:13,440 of the survey is complete at like 99 2353 01:25:18,229 --> 01:25:15,600 level there's only a handful of objects 2354 01:25:20,390 --> 01:25:18,239 out there that we haven't seen yet that 2355 01:25:22,550 --> 01:25:20,400 we don't know about so that's a very 2356 01:25:23,910 --> 01:25:22,560 good news for us because actually the 2357 01:25:27,750 --> 01:25:23,920 one that 2358 01:25:29,430 --> 01:25:27,760 that impacted um in mexico and that 2359 01:25:31,110 --> 01:25:29,440 caused the dinosaur extinction i believe 2360 01:25:33,669 --> 01:25:31,120 it was a really big monster it was 2361 01:25:36,070 --> 01:25:33,679 something like 10 kilometers so we know 2362 01:25:37,990 --> 01:25:36,080 we know about those objects but still 2363 01:25:40,550 --> 01:25:38,000 there are a lot of smaller objects that 2364 01:25:42,950 --> 01:25:40,560 can also cause significant damage so 2365 01:25:44,950 --> 01:25:42,960 nasa has a goal to really map out all 2366 01:25:48,229 --> 01:25:44,960 the objects that are larger than about 2367 01:25:50,229 --> 01:25:48,239 130 meters in diameter because they can 2368 01:25:52,550 --> 01:25:50,239 they can still cause a significant uh 2369 01:25:55,830 --> 01:25:52,560 damage and definitely efforts are on the 2370 01:25:57,510 --> 01:25:55,840 way to to really make sure that we know 2371 01:25:59,350 --> 01:25:57,520 where everything is is in near 2372 01:26:01,430 --> 01:25:59,360 population 2373 01:26:03,030 --> 01:26:01,440 um you know i'll add to that also that 2374 01:26:05,189 --> 01:26:03,040 all of the information about every 2375 01:26:06,950 --> 01:26:05,199 asteroid that has been discovered and is 2376 01:26:08,790 --> 01:26:06,960 now being tracked all of its online it's 2377 01:26:11,110 --> 01:26:08,800 available to anyone and we actually here 2378 01:26:13,830 --> 01:26:11,120 at jpl have a twitter account called 2379 01:26:15,430 --> 01:26:13,840 asteroid watch and we don't tell you 2380 01:26:16,709 --> 01:26:15,440 about every single asteroid but we can 2381 01:26:19,430 --> 01:26:16,719 direct you to the full list it's 2382 01:26:21,110 --> 01:26:19,440 enormous you'd be surprised um but we do 2383 01:26:23,590 --> 01:26:21,120 tell you if there's an asteroid that is 2384 01:26:25,830 --> 01:26:23,600 going to come within about uh three or 2385 01:26:27,110 --> 01:26:25,840 four lunar distances that kind of puts a 2386 01:26:28,870 --> 01:26:27,120 good picture in people's mind about how 2387 01:26:30,870 --> 01:26:28,880 far out that is that it would be about a 2388 01:26:32,229 --> 01:26:30,880 million miles right so we when when 2389 01:26:34,149 --> 01:26:32,239 they're coming within that distance 2390 01:26:36,550 --> 01:26:34,159 we'll often tweet about them just so 2391 01:26:38,629 --> 01:26:36,560 that uh people get a feel for how often 2392 01:26:40,470 --> 01:26:38,639 that actually does happen it happens 2393 01:26:43,110 --> 01:26:40,480 quite a bit i think the 2394 01:26:44,790 --> 01:26:43,120 one passes between earth and the moon um 2395 01:26:47,590 --> 01:26:44,800 every couple of weeks and and those are 2396 01:26:49,270 --> 01:26:47,600 mostly very very small objects that 2397 01:26:50,470 --> 01:26:49,280 would just burn up in the atmosphere 2398 01:26:52,629 --> 01:26:50,480 even if they did 2399 01:26:54,070 --> 01:26:52,639 get close to earth 2400 01:26:55,750 --> 01:26:54,080 uh we have a question over here in the 2401 01:26:57,350 --> 01:26:55,760 back let me get you the microphone oh 2402 01:26:59,189 --> 01:26:57,360 you've got one great 2403 01:27:01,030 --> 01:26:59,199 um with all the advances that we've had 2404 01:27:03,270 --> 01:27:01,040 in the past over 50 years 2405 01:27:04,470 --> 01:27:03,280 since we launched when was warrior one 2406 01:27:07,990 --> 01:27:04,480 launched 2407 01:27:10,229 --> 01:27:08,000 97 87 77 all the advances that we've had 2408 01:27:11,510 --> 01:27:10,239 in technology since are there any plans 2409 01:27:14,149 --> 01:27:11,520 to send other 2410 01:27:15,590 --> 01:27:14,159 spacecrafts out into the universe to get 2411 01:27:18,229 --> 01:27:15,600 other data that we might not be able to 2412 01:27:19,910 --> 01:27:18,239 get in be getting right now from voyager 2413 01:27:21,910 --> 01:27:19,920 i have plans to 2414 01:27:23,669 --> 01:27:21,920 well voyager is the only 2415 01:27:24,950 --> 01:27:23,679 the spacecraft that's leaving the solar 2416 01:27:27,590 --> 01:27:24,960 system and you can think of it as our 2417 01:27:29,669 --> 01:27:27,600 silent ambassador going out into space 2418 01:27:31,430 --> 01:27:29,679 it carries a gold record it has 2419 01:27:33,750 --> 01:27:31,440 information without the sights and 2420 01:27:35,270 --> 01:27:33,760 sounds of earth and even how to find us 2421 01:27:37,030 --> 01:27:35,280 if you can read the pictures on the 2422 01:27:39,030 --> 01:27:37,040 cover of the record 2423 01:27:40,950 --> 01:27:39,040 there are other missions in the you know 2424 01:27:43,110 --> 01:27:40,960 just the planning and thought processes 2425 01:27:45,350 --> 01:27:43,120 to perhaps go out further to other 2426 01:27:47,669 --> 01:27:45,360 planets new horizons for instance is 2427 01:27:49,669 --> 01:27:47,679 going to fly by pluto and then on out to 2428 01:27:53,590 --> 01:27:49,679 a kuiper belt object so we're slowly 2429 01:27:55,270 --> 01:27:53,600 expanding the range in which we explore 2430 01:27:58,310 --> 01:27:55,280 we are getting very close to the end of 2431 01:27:59,990 --> 01:27:58,320 our time now on with nasa television um 2432 01:28:01,669 --> 01:28:00,000 you all are invited to stay and and 2433 01:28:04,229 --> 01:28:01,679 answer some more questions after our 2434 01:28:06,629 --> 01:28:04,239 broadcast ends for
