These are the user uploaded subtitles that are being translated: 1 00:00:16,190 --> 00:00:18,366 We are reaching the end of the mission. 2 00:00:18,844 --> 00:00:20,629 Hopefully it doesn't... 3 00:00:21,847 --> 00:00:24,633 get lost because of an anomaly. 4 00:00:25,895 --> 00:00:28,506 Uh, but it's, uh it is 5 00:00:28,550 --> 00:00:30,552 uh, yeah, it is... 6 00:00:31,466 --> 00:00:33,207 a lot of pressure. 7 00:00:34,425 --> 00:00:36,819 You don't wanna let down Voyager. 8 00:01:14,944 --> 00:01:16,337 Hello? 9 00:01:16,380 --> 00:01:18,033 Jeff, are you there? 10 00:01:18,078 --> 00:01:19,340 Oh, yeah, yeah, I'm here. 11 00:01:19,383 --> 00:01:20,863 So, what happened? 12 00:01:20,906 --> 00:01:22,604 It's been really wild. 13 00:01:22,646 --> 00:01:26,347 Yeah, um, basically the, um 14 00:01:26,390 --> 00:01:28,131 certain things happened, 15 00:01:28,175 --> 00:01:30,220 unusual things happened during the mag-roll 16 00:01:30,264 --> 00:01:32,222 that should have not happened. 17 00:01:32,265 --> 00:01:36,226 Still, I mean, we do not know we don't know everything. 18 00:01:36,270 --> 00:01:38,140 If we can talk a little bit later, 19 00:01:38,185 --> 00:01:39,795 people here are coming into my office 20 00:01:39,838 --> 00:01:41,536 - and want to know... - Okay. 21 00:01:41,579 --> 00:01:42,884 ...what's going on, what's happening? 22 00:01:42,928 --> 00:01:44,539 Have we been able to recover? 23 00:02:02,861 --> 00:02:05,037 Okay, welcome to Voyager. 24 00:02:06,648 --> 00:02:08,650 Put those lights on. 25 00:02:13,916 --> 00:02:15,222 Okay. 26 00:02:15,831 --> 00:02:17,572 Wanna get the blinds open. 27 00:02:18,834 --> 00:02:20,531 We have our library, 28 00:02:20,575 --> 00:02:23,273 I'm not sure what this is on the floor over here. 29 00:02:24,361 --> 00:02:26,276 This is our kitchen area, 30 00:02:26,885 --> 00:02:29,758 offices for the engineers, 31 00:02:29,801 --> 00:02:32,369 and, of course, this is Suzy's office here. 32 00:02:33,543 --> 00:02:34,850 Suzy, take one. 33 00:02:36,112 --> 00:02:37,679 My name is Suzanne Dodd 34 00:02:37,722 --> 00:02:39,289 and I'm the Voyager project manager 35 00:02:39,333 --> 00:02:41,161 here at the Jet Propulsion Laboratory. 36 00:02:41,900 --> 00:02:46,122 I think, um, being here, um... 37 00:02:46,992 --> 00:02:48,516 you're forgotten here. 38 00:02:55,043 --> 00:02:58,700 Where we are now is a complex called Woodbury, 39 00:02:58,743 --> 00:03:00,441 which is the name of the street it's on. 40 00:03:01,268 --> 00:03:04,575 It's about a mile from JPL, I think. 41 00:03:04,619 --> 00:03:06,490 Next to McDonald's. 42 00:03:09,493 --> 00:03:12,975 NASA management doesn't really think of Voyager, 43 00:03:13,018 --> 00:03:14,411 doesn't really worry about Voyager. 44 00:03:15,456 --> 00:03:17,588 It's out of sight, out of mind kind of thing. 45 00:03:18,589 --> 00:03:20,417 That wasn't always the case. 46 00:03:22,853 --> 00:03:24,204 The mission of Voyager 47 00:03:24,247 --> 00:03:26,162 is the search for knowledge 48 00:03:26,206 --> 00:03:28,556 that will widen the horizons of generations to come. 49 00:03:33,691 --> 00:03:35,476 The whole community, the science community, 50 00:03:35,519 --> 00:03:36,954 the political community, 51 00:03:36,999 --> 00:03:39,262 were really hot to do this mission. 52 00:03:39,305 --> 00:03:41,046 To help you feel 53 00:03:41,090 --> 00:03:42,656 the staggering dimensions of this mission, 54 00:03:42,700 --> 00:03:44,659 it's worth recalling how it got here. 55 00:03:45,180 --> 00:03:49,359 In the late '60s, we learned it was possible 56 00:03:49,403 --> 00:03:51,492 to use the gravity of one planet 57 00:03:51,535 --> 00:03:54,059 to accelerate the spacecraft 58 00:03:54,103 --> 00:03:55,626 and go to another planet. 59 00:03:56,410 --> 00:03:58,107 And then somebody found out 60 00:03:58,150 --> 00:04:02,198 that there's a very unusual alignment in '77. 61 00:04:02,807 --> 00:04:05,027 All four of the giant outer planets, 62 00:04:05,070 --> 00:04:07,508 Jupiter, Saturn, and Uranus and Neptune, 63 00:04:07,551 --> 00:04:10,685 would be aligned on the same side of the sun. 64 00:04:12,339 --> 00:04:14,863 That only occurs once every 176 years, 65 00:04:14,906 --> 00:04:18,432 where you can go from Jupiter to Saturn to Uranus to Neptune. 66 00:04:19,214 --> 00:04:20,825 The last time that happened 67 00:04:20,869 --> 00:04:23,219 was during Thomas Jefferson's administration. 68 00:04:25,090 --> 00:04:27,789 In '77, it happens again. 69 00:04:27,832 --> 00:04:30,792 When the Space Age itself is only 20 years old. 70 00:04:32,620 --> 00:04:34,404 As soon as people realize that, 71 00:04:34,448 --> 00:04:36,232 they think we've got to send a mission to do that. 72 00:04:36,276 --> 00:04:38,321 The Voyager Spacecraft 73 00:04:38,365 --> 00:04:40,758 will carry the eyes of men farther than they've ever been 74 00:04:40,802 --> 00:04:43,457 and closer to the very limits of our solar system. 75 00:04:51,378 --> 00:04:52,814 They said, "Okay, what we're gonna do 76 00:04:52,857 --> 00:04:54,468 is we're gonna have two spacecrafts 77 00:04:54,511 --> 00:04:56,818 for redundancies." 78 00:04:56,861 --> 00:04:58,602 Cape Canaveral Florida 79 00:04:58,646 --> 00:05:00,691 sent another unmanned Voyager spacecraft 80 00:05:00,735 --> 00:05:02,998 on its way to Jupiter and Saturn. 81 00:05:03,999 --> 00:05:05,392 That gave us better assurance 82 00:05:05,435 --> 00:05:07,394 that at least one could finish 83 00:05:07,437 --> 00:05:10,745 what's called the Grand Tour of the giant outer planets. 84 00:05:11,223 --> 00:05:14,009 What we know about Jupiter 85 00:05:14,052 --> 00:05:18,535 and Saturn, Uranus, and Neptune 86 00:05:18,579 --> 00:05:21,451 were all achieved by a single mission, 87 00:05:21,495 --> 00:05:25,847 flying breakneck speed through the solar system. 88 00:05:27,065 --> 00:05:28,806 Not since 1969 89 00:05:28,850 --> 00:05:30,852 and man's first footsteps on the moon 90 00:05:30,895 --> 00:05:35,378 has space captured the nation's imagination to this degree. 91 00:05:35,422 --> 00:05:37,772 We are in the process of having completed 92 00:05:37,815 --> 00:05:39,948 the reconnaissance of the solar system. 93 00:05:39,991 --> 00:05:42,777 It's a fantastic historical achievement. 94 00:05:44,431 --> 00:05:46,215 The scientists and friends are here 95 00:05:46,258 --> 00:05:49,349 to celebrate the completion of Voyager's Grand Tour. 96 00:05:49,392 --> 00:05:51,568 There's a strong feeling of elation here 97 00:05:51,612 --> 00:05:54,528 as many continue to ride the crest of a wave 98 00:05:54,571 --> 00:05:57,487 that carried the mission to a monumental success. 99 00:06:00,577 --> 00:06:02,362 And after that, 100 00:06:02,405 --> 00:06:04,407 pretty much everybody thought Voyager was over. 101 00:06:04,973 --> 00:06:08,411 I think we probably had about 1,200 engineers working on it. 102 00:06:08,455 --> 00:06:12,372 I I I you know, I I don't even know I 103 00:06:12,415 --> 00:06:14,983 how many people are working on Voyager right now. 104 00:06:15,026 --> 00:06:16,985 Probably not more than ten or 15. 105 00:06:17,028 --> 00:06:20,292 Today we have 12 people that fly two spacecraft. 106 00:06:20,771 --> 00:06:23,774 They've dedicated their whole career to Voyager. 107 00:06:37,005 --> 00:06:38,528 It's not that we fly by Neptune 108 00:06:38,572 --> 00:06:40,225 and then everything's done. 109 00:06:40,269 --> 00:06:42,227 Voyager has long legs. 110 00:06:42,271 --> 00:06:44,012 As far as continuation of the mission, 111 00:06:44,055 --> 00:06:46,971 we do plan to continue tracking Voyager 112 00:06:47,015 --> 00:06:49,539 for as long as it's possible. 113 00:06:49,582 --> 00:06:51,933 We move into the interstellar mission, 114 00:06:51,976 --> 00:06:55,589 which will be staffed by a much lower staffing level. 115 00:06:55,632 --> 00:07:02,117 This is the next step of exploration for mankind. 116 00:07:02,160 --> 00:07:04,772 The first to interstellar space. We made it. 117 00:07:25,096 --> 00:07:26,184 Hello? 118 00:07:27,272 --> 00:07:28,360 Hello? 119 00:07:34,323 --> 00:07:35,411 Hello? 120 00:07:46,248 --> 00:07:47,597 Hmm. 121 00:07:56,824 --> 00:07:58,913 Hello?

146 00:09:04,631 --> 00:09:06,110 '73. 147 00:09:08,504 --> 00:09:12,160 I was a spacecraft team chief through mid '81. 148 00:09:13,161 --> 00:09:16,251 Much later in my career, they called me back. 149 00:09:16,947 --> 00:09:20,472 The experience is different from day to day, 150 00:09:20,516 --> 00:09:22,344 but it's still the same goal. 151 00:09:22,866 --> 00:09:24,607 There's a mission to be flown. 152 00:09:24,651 --> 00:09:28,872 We need to put the instruments through their paces, 153 00:09:28,916 --> 00:09:31,353 we need to make observations, 154 00:09:31,396 --> 00:09:33,007 we need to look for things 155 00:09:33,050 --> 00:09:35,662 where we're not sure what we're gonna find. 156 00:09:35,705 --> 00:09:37,794 Just to get the science back. 157 00:09:37,838 --> 00:09:41,145 And that's really the role of of these teams. 158 00:09:46,411 --> 00:09:48,109 Our focus is to make sure 159 00:09:48,152 --> 00:09:50,502 that we get the scientists the data that they want. 160 00:09:50,546 --> 00:09:52,330 No space driver's ever been out this far. 161 00:10:11,306 --> 00:10:14,004 Astrophysicists, they're tickled to death 162 00:10:14,048 --> 00:10:15,832 that both Voyagers have survived 163 00:10:15,876 --> 00:10:18,356 and are taking data in interstellar space. 164 00:10:21,751 --> 00:10:23,710 There's a chance to see something new 165 00:10:23,753 --> 00:10:27,583 or learn something that hasn't been learned or observed before. 166 00:10:27,627 --> 00:10:31,152 My best day is when we have a staff meeting 167 00:10:31,195 --> 00:10:33,284 and Ed Stone is there 168 00:10:33,328 --> 00:10:36,984 and he's talking about what they're seeing. 169 00:10:40,683 --> 00:10:42,685 We're talking with Dr. Edward Stone, 170 00:10:42,729 --> 00:10:44,469 Voyager project scientist. 171 00:10:44,513 --> 00:10:47,821 Dr. Stone is a professor of physics at, uh, CalTech. 172 00:10:48,386 --> 00:10:50,824 Doctor, um, what are the responsibility 173 00:10:50,867 --> 00:10:53,870 your responsibilities here at JPL? 174 00:10:53,914 --> 00:10:56,133 I'm Ed Stone, I'm the chief scientist 175 00:10:56,177 --> 00:10:58,048 for the mission called the Project Scientist 176 00:10:58,092 --> 00:10:59,267 for Voyager. 177 00:10:59,310 --> 00:11:00,877 Dr. Ed Stone. 178 00:11:00,921 --> 00:11:02,662 Ed Stone, the Voyager project scientist, 179 00:11:02,705 --> 00:11:04,315 has joined us again. 180 00:11:04,359 --> 00:11:06,927 The, uh, Voyager project scientist, Dr. Ed Stone. 181 00:11:07,754 --> 00:11:10,974 The one and the only project scientist 182 00:11:11,018 --> 00:11:13,150 that Voyager has ever known. 183 00:11:13,194 --> 00:11:14,412 The one and only. 184 00:11:16,937 --> 00:11:19,069 Voyager was really a pathfinder. 185 00:11:19,853 --> 00:11:22,725 The fact that it lasted 42 years and is still working 186 00:11:22,769 --> 00:11:24,684 is something we could not have imagined 187 00:11:24,727 --> 00:11:26,033 back in those days. 188 00:11:26,598 --> 00:11:29,297 What we're learning is how this the wind of the sun 189 00:11:29,340 --> 00:11:32,169 interacts with the wind from the other stars nearby. 190 00:11:34,215 --> 00:11:37,697 The Voyager 1 entered interstellar space in 2012 191 00:11:38,306 --> 00:11:40,221 and it was in the northern hemisphere 192 00:11:40,264 --> 00:11:42,223 of the heliosphere. 193 00:11:42,266 --> 00:11:45,182 The heliosphere's a huge bubble the sun creates around itself. 194 00:11:46,009 --> 00:11:47,881 Voyager 1 was in the North. 195 00:11:47,924 --> 00:11:49,447 Voyager 2 was in the South. 196 00:11:50,797 --> 00:11:52,320 We were surprised to find that, 197 00:11:52,363 --> 00:11:54,452 in terms of where the heliopause is, 198 00:11:54,496 --> 00:11:56,759 it's almost as far from the sun in the South 199 00:11:56,803 --> 00:11:57,891 as it is in the North. 200 00:11:59,631 --> 00:12:02,025 By measuring the distance to the sun 201 00:12:02,069 --> 00:12:03,548 at two different points, 202 00:12:03,592 --> 00:12:05,159 it helps us model this interaction 203 00:12:05,202 --> 00:12:08,379 between the heliosphere and interstellar space. 204 00:12:09,859 --> 00:12:11,339 It's a very important interaction 205 00:12:11,382 --> 00:12:13,384 because the heliosphere shields Earth. 206 00:12:13,907 --> 00:12:16,779 Over 70% of what's outside can't get in 207 00:12:16,823 --> 00:12:19,956 because of this outward flow of the wind pushing things back. 208 00:12:20,870 --> 00:12:23,830 The size of the heliosphere is really very important 209 00:12:23,873 --> 00:12:26,180 in terms of the radiation environment here on Earth. 210 00:12:27,790 --> 00:12:29,531 We had no good idea 211 00:12:29,574 --> 00:12:31,315 how big the heliospheric bubble was. 212 00:12:31,838 --> 00:12:33,274 That's what the Voyager determined. 213 00:12:36,190 --> 00:12:38,235 It changed our view of the solar system. 214 00:12:52,293 --> 00:12:55,862 What Voyagers have told us are the first hints 215 00:12:55,905 --> 00:12:58,038 of what's in the space between the stars 216 00:12:58,081 --> 00:13:01,258 outside the heliopause, and the scientists there 217 00:13:01,302 --> 00:13:03,957 are fundamentally having to change their models 218 00:13:04,000 --> 00:13:06,786 of of what they thought that space was like. 219 00:13:09,919 --> 00:13:11,834 To find out what's out there, 220 00:13:11,878 --> 00:13:13,662 it's just it's just amazing. 221 00:13:18,188 --> 00:13:20,930 People really thirst for that fundamental knowledge 222 00:13:20,974 --> 00:13:24,934 that's being exposed, uh, by the Voyager spacecraft. 223 00:13:33,508 --> 00:13:37,207 It's about giving people the sense of exploration 224 00:13:37,251 --> 00:13:38,469 and adventure... 225 00:13:39,906 --> 00:13:41,255 and hope. 226 00:13:47,391 --> 00:13:48,871 And that's very important to us. 227 00:13:50,917 --> 00:13:52,396 The science return is there. 228 00:13:52,440 --> 00:13:54,268 If we can keep the spacecraft healthy, 229 00:13:54,311 --> 00:13:56,705 the science takes care of itself and will come back. 230 00:14:01,492 --> 00:14:03,233 There's still discoveries out there. 231 00:14:04,669 --> 00:14:06,671 But it's a lot more challenging now. 232 00:14:09,065 --> 00:14:13,983 For Voyager 1, the one way light-time is 20 hours. 233 00:14:16,159 --> 00:14:18,727 That means the signal coming from Voyager 1 234 00:14:18,770 --> 00:14:21,730 takes over 20 hours to get to Earth. 235 00:14:21,773 --> 00:14:23,123 Moving at the speed of light, 236 00:14:23,166 --> 00:14:25,952 a zippy 186,000 miles per second. 237 00:14:25,995 --> 00:14:27,997 Voyager 2 is not far behind, 238 00:14:28,041 --> 00:14:31,218 it's about 17 light-hours away from Earth. 239 00:14:32,567 --> 00:14:34,612 If I come in on a Monday morning 240 00:14:34,656 --> 00:14:38,312 and I say, "Hey, Voyager. How you doing? Good morning," 241 00:14:38,355 --> 00:14:40,531 it's gonna take me 'til Tuesday afternoon 242 00:14:40,575 --> 00:14:42,707 that that I get a response back from Voyager 243 00:14:42,751 --> 00:14:44,274 that says, "Hi, I'm doing great." 244 00:14:49,932 --> 00:14:52,282 The other issue is that, um, 245 00:14:52,326 --> 00:14:56,243 we're all older now and that age, uh, 246 00:14:56,286 --> 00:15:00,725 casts a sort of a shadow over the things that we do. 247 00:15:02,771 --> 00:15:04,816 Thi this ship was launched, you know, what, 248 00:15:04,860 --> 00:15:06,253 45 years ago? 249 00:15:06,862 --> 00:15:08,864 Well, people don't know the details 250 00:15:08,908 --> 00:15:10,866 of what is behind it. 251 00:15:10,910 --> 00:15:12,999 What are they now? They're in their 80s and 90s. 252 00:15:13,608 --> 00:15:15,175 I mean, I'm 87. 253 00:15:16,567 --> 00:15:18,134 That's a real issue. 254 00:15:18,178 --> 00:15:21,007 Nowadays, when we're talking about, um, 255 00:15:21,050 --> 00:15:22,530 decisions we're making 256 00:15:22,573 --> 00:15:24,184 in the engineering world on the project, 257 00:15:24,227 --> 00:15:25,663 a lot of it goes way back 258 00:15:25,707 --> 00:15:27,970 to when they built the spacecraft. 259 00:15:29,754 --> 00:15:32,453 What were the specifications on this part? 260 00:15:32,496 --> 00:15:34,020 What was it tested at? 261 00:15:35,717 --> 00:15:37,849 How conservative were they when they put this number 262 00:15:37,893 --> 00:15:41,375 on this piece of paper 40 years ago? 263 00:15:42,463 --> 00:15:44,552 And you go back 264 00:15:44,595 --> 00:15:46,858 and you try to find those original engineers 265 00:15:46,902 --> 00:15:48,425 that wrote the document 266 00:15:48,469 --> 00:15:51,211 and a lot of them are no longer alive. 267 00:15:52,995 --> 00:15:55,824 I read through these documents 268 00:15:55,867 --> 00:15:59,741 that I worked on back in the beginning, 269 00:16:01,264 --> 00:16:04,093 signed by all these people that I had worked with. 270 00:16:05,529 --> 00:16:06,966 Most of those people are gone. 271 00:16:08,968 --> 00:16:12,449 It may be a race between how long we, as individuals live, 272 00:16:12,493 --> 00:16:14,364 versus how long the the spacecraft 273 00:16:14,408 --> 00:16:16,192 can still communicate with us. 274 00:16:17,889 --> 00:16:19,761 There's such a knowledge base 275 00:16:19,804 --> 00:16:21,806 that's in the engineer's head, 276 00:16:22,459 --> 00:16:24,679 that it's critical to have people 277 00:16:24,722 --> 00:16:26,333 who are on the project 278 00:16:26,376 --> 00:16:28,117 and have been on the project a long time, 279 00:16:28,161 --> 00:16:30,511 continue to work on the project as long as possible. 280 00:16:31,164 --> 00:16:34,645 You know, Jeff Hall, Sun, Enrique. 281 00:16:35,907 --> 00:16:38,127 Most of us are single point failures. 282 00:16:38,171 --> 00:16:40,912 Yeah, I'll be 70 next week. 283 00:16:40,956 --> 00:16:43,437 Almost in the old days. 284 00:16:44,090 --> 00:16:45,961 I've been working on Voyager for so long, 285 00:16:46,005 --> 00:16:49,965 I cannot imagine, uh, leaving the project. 286 00:16:50,879 --> 00:16:53,055 They have what you can't get from paper. 287 00:16:53,099 --> 00:16:54,535 They understand the idiosyncrasies 288 00:16:54,578 --> 00:16:56,319 of the spacecraft. 289 00:16:56,363 --> 00:16:59,844 Their whole professional careers are on this mission 290 00:16:59,888 --> 00:17:01,803 and making this mission successful. 291 00:17:06,676 --> 00:17:09,028 It's hard for me to just see this machine, 292 00:17:09,070 --> 00:17:11,943 it's kind of like a part of, uh... 293 00:17:12,857 --> 00:17:13,989 me. 294 00:17:15,817 --> 00:17:17,079 Very proud of what I'm doing, 295 00:17:18,211 --> 00:17:20,126 especially from my background. 296 00:17:21,170 --> 00:17:23,215 I was born and raised in Mexico. 297 00:17:24,042 --> 00:17:27,262 I was born and raised in Korea, South Korea, 298 00:17:27,307 --> 00:17:29,700 in a small farming village. 299 00:17:30,788 --> 00:17:33,095 In Colombia, as a child, 300 00:17:33,139 --> 00:17:36,229 I never, in my wildest dreams, 301 00:17:36,272 --> 00:17:37,839 thought that I would end up 302 00:17:37,882 --> 00:17:40,233 working with this particular project. 303 00:17:40,276 --> 00:17:42,713 That was never in my mind. 304 00:17:43,714 --> 00:17:45,586 I grew up in , Mississippi. 305 00:17:46,108 --> 00:17:48,241 I wanted to get into a technical field, 306 00:17:48,284 --> 00:17:50,330 but during that time segregation was big 307 00:17:50,373 --> 00:17:51,896 and weren't allowed to go to schools 308 00:17:51,940 --> 00:17:54,682 where they offered technical degrees. 309 00:17:55,291 --> 00:17:57,554 So, I went to school in Alabama. 310 00:17:57,598 --> 00:18:00,296 Tuskegee Institute, now Tuskegee University. 311 00:18:03,952 --> 00:18:07,651 I came to the States for a small vacation. 312 00:18:08,217 --> 00:18:12,395 November, 1968. 313 00:18:13,440 --> 00:18:16,486 Then I met my to-be wife. 314 00:18:17,270 --> 00:18:18,749 My guardian angel. 315 00:18:21,230 --> 00:18:23,406 I immigrated to United States 316 00:18:23,450 --> 00:18:25,321 after high school. 317 00:18:27,018 --> 00:18:29,934 But I came in December 1977. 318 00:18:31,762 --> 00:18:34,069 But I didn't know about the Voyager back then. 319 00:18:38,073 --> 00:18:39,770 I came on in '78, 320 00:18:39,814 --> 00:18:41,337 just prior to Jupiter encounter. 321 00:18:43,296 --> 00:18:46,647 After exactly 18 months of flight, 322 00:18:46,690 --> 00:18:49,998 Voyager 1 will reach Jupiter on March 5th. 323 00:18:51,260 --> 00:18:52,653 For Jupiter encounter, 324 00:18:52,696 --> 00:18:54,568 we had to design and and develop 325 00:18:54,611 --> 00:18:57,223 new and different sequences or get pictures 326 00:18:57,266 --> 00:18:59,442 and whatever kind of science it would take. 327 00:19:01,096 --> 00:19:02,880 We didn't know what we were gonna find. 328 00:19:03,751 --> 00:19:07,058 We sort of set up the camera on the spacecraft 329 00:19:07,102 --> 00:19:09,017 and we would just stare at the planet 330 00:19:09,060 --> 00:19:10,888 and we'd take pictures. 331 00:19:13,761 --> 00:19:15,850 And the pictures 332 00:19:16,633 --> 00:19:18,157 would produce movies. 333 00:19:27,296 --> 00:19:29,255 I mean, it was incredible. 334 00:19:30,299 --> 00:19:32,910 We would see something that we can't even describe. 335 00:19:34,477 --> 00:19:37,480 It it appears to be radiating 30% more energy 336 00:19:37,524 --> 00:19:39,656 than it ab absorbs from the sun. 337 00:19:40,309 --> 00:19:42,442 In terms of the foot of the flux tube, 338 00:19:42,485 --> 00:19:43,878 those are the same magnetic field lines 339 00:19:43,921 --> 00:19:45,880 that thread the Taurus, so yes... 340 00:19:45,923 --> 00:19:49,100 We were immersed with one discovery after the other. 341 00:19:49,144 --> 00:19:50,754 The main surprise 342 00:19:50,798 --> 00:19:52,669 was the amount of activity on Io. 343 00:19:52,713 --> 00:19:54,236 You showed us the picture of the volcano there 344 00:19:54,280 --> 00:19:55,716 and that was that was news. 345 00:19:56,673 --> 00:19:59,067 Before Voyager, the only known active volcanoes 346 00:19:59,110 --> 00:20:01,200 in the solar system were here on Earth. 347 00:20:03,245 --> 00:20:04,812 And then we flew by Io, 348 00:20:04,855 --> 00:20:06,466 which is a moon about the size of our moon. 349 00:20:06,901 --> 00:20:10,644 It had ten times the volcanic activity of Earth. 350 00:20:11,210 --> 00:20:15,039 Suddenly, we realized our terra-centric view 351 00:20:15,083 --> 00:20:17,607 of what the planets and solar system were like. 352 00:20:19,305 --> 00:20:21,698 Nature was really doing these incredible things. 353 00:20:24,962 --> 00:20:26,094 It was exciting. 354 00:20:26,790 --> 00:20:32,013 We were all early in our Voyager experience. 355 00:20:36,235 --> 00:20:38,933 That was a long time ago. 356 00:20:43,285 --> 00:20:46,070 There is still a lot more we need to learn 357 00:20:46,114 --> 00:20:47,463 about the solar system. 358 00:20:48,595 --> 00:20:51,815 But the spacecraft isn't all as it was 359 00:20:51,859 --> 00:20:53,077 40 years ago. 360 00:20:53,643 --> 00:20:55,036 I like to think of the spacecraft 361 00:20:55,079 --> 00:20:56,559 as senior citizens. 362 00:20:56,603 --> 00:20:58,605 Over time they've aged differently, 363 00:20:58,648 --> 00:21:00,346 different things have broken, 364 00:21:00,389 --> 00:21:03,131 so they don't behave quite the same today 365 00:21:03,174 --> 00:21:04,393 as they did at launch. 366 00:21:16,362 --> 00:21:20,279 Voyager 2 has more challenges than Voyager 1. 367 00:21:25,632 --> 00:21:29,505 Voyager 2 is colder and has less power margin. 368 00:21:30,811 --> 00:21:33,292 Honestly, we don't really know why it's colder. 369 00:21:33,335 --> 00:21:34,815 It goes back to the fact 370 00:21:34,858 --> 00:21:36,599 that over time these twin spacecraft 371 00:21:36,643 --> 00:21:38,384 have aged differently. 372 00:21:39,210 --> 00:21:41,561 The whole system is cooling down. 373 00:21:41,604 --> 00:21:45,478 In particular, the hydrazine, the propellant 374 00:21:45,521 --> 00:21:48,002 that we use to keep the spacecraft oriented 375 00:21:48,045 --> 00:21:49,917 to point back to Earth. 376 00:21:49,960 --> 00:21:52,354 16 tiny rocket thrusters 377 00:21:52,398 --> 00:21:54,704 fueled by decomposing hydrazine 378 00:21:54,748 --> 00:21:58,708 turn the craft or change its velocity when required. 379 00:22:00,710 --> 00:22:02,538 We're within a couple of degrees 380 00:22:02,582 --> 00:22:04,540 of having that freeze. 381 00:22:06,281 --> 00:22:09,153 As it cools down and eventually freezes, 382 00:22:09,197 --> 00:22:11,634 uh, we can no longer point the spacecraft 383 00:22:11,678 --> 00:22:13,288 and it will just drift off 384 00:22:13,332 --> 00:22:15,638 and that'll be the end of the mission. 385 00:22:24,081 --> 00:22:27,302 One of the other sticky issues on Voyager 2, 386 00:22:27,346 --> 00:22:30,479 the only antenna that can talk to Voyager 2 387 00:22:30,523 --> 00:22:34,918 is DSS, Deep Space Station 43, in Canberra, Australia. 388 00:22:34,962 --> 00:22:41,403 ♪ 389 00:22:50,107 --> 00:22:54,895 DSS-43 is gonna be down from February of 2020 390 00:22:54,938 --> 00:22:58,638 clear out to about as late as December 2020. 391 00:22:58,681 --> 00:23:04,165 When that antenna is down, we cannot command Voyager 2. 392 00:23:04,208 --> 00:23:06,559 The mammoth electronic ears 393 00:23:06,602 --> 00:23:08,691 of today's deep space network 394 00:23:08,735 --> 00:23:12,956 can and do continuously track and receive data 395 00:23:13,000 --> 00:23:15,959 from probes to the edge of our solar system. 396 00:23:22,531 --> 00:23:26,013 We have stations North of Barstow, California, 397 00:23:26,056 --> 00:23:27,580 others in Madrid, 398 00:23:27,623 --> 00:23:30,104 and another one in Australia in Canberra. 399 00:23:39,113 --> 00:23:40,506 Voyager 2 can only be seen 400 00:23:40,549 --> 00:23:41,768 in the southern hemisphere 401 00:23:41,811 --> 00:23:43,247 because it's so far down 402 00:23:43,291 --> 00:23:44,901 and out of the plane of the planets. 403 00:23:46,163 --> 00:23:47,730 So, it can only be seen 404 00:23:47,774 --> 00:23:49,993 by the Australian Deep Space Center Site 405 00:23:50,037 --> 00:23:51,952 that's located outside of Canberra. 406 00:24:03,093 --> 00:24:04,965 DSN announced 407 00:24:05,008 --> 00:24:07,663 that they were going to be having some big maintenance 408 00:24:07,707 --> 00:24:11,667 that they had to do on the Canberra station, 409 00:24:11,711 --> 00:24:13,060 the 70 meter station. 410 00:24:22,417 --> 00:24:24,375 We'll still get downlight, 411 00:24:24,419 --> 00:24:27,291 we'll be able to look in and view Voyager 2, 412 00:24:27,335 --> 00:24:28,858 make sure it's healthy, 413 00:24:28,902 --> 00:24:31,339 but we don't have uplink capabilities. 414 00:24:33,167 --> 00:24:35,256 So, if there's a problem with the spacecraft, 415 00:24:35,299 --> 00:24:37,780 we can't send something to fix it. 416 00:24:39,434 --> 00:24:42,306 So, we're really kind of, um 417 00:24:42,568 --> 00:24:44,395 scrambling is not the right word, 418 00:24:44,439 --> 00:24:47,486 but we're maybe it's controlled scrambling? 419 00:24:48,399 --> 00:24:50,750 Right now, what we have for Voyager 2 420 00:24:50,793 --> 00:24:52,360 is unsustainable. 421 00:24:52,403 --> 00:24:53,709 Period. 422 00:24:54,580 --> 00:24:57,844 This spacecraft would not survive the downtime. 423 00:24:59,889 --> 00:25:02,588 We have to put enough margin on our power and thermal 424 00:25:02,631 --> 00:25:05,329 at the start of that antenna downtime 425 00:25:05,373 --> 00:25:07,027 to last a year. 426 00:25:07,070 --> 00:25:09,116 Trying to plan how we get through that period 427 00:25:09,159 --> 00:25:11,684 without causing something to freeze. 428 00:25:24,435 --> 00:25:26,263 So, full disclosure, 429 00:25:26,307 --> 00:25:28,396 I've had a lot of trouble with this car this year. 430 00:25:28,439 --> 00:25:29,571 We cannot... 431 00:25:31,094 --> 00:25:33,357 fix it, uh, although we're close. 432 00:25:33,401 --> 00:25:35,838 It's the engine control module, ECM. 433 00:25:36,317 --> 00:25:38,362 I'm trying to think of a way it's kind of like, 434 00:25:38,406 --> 00:25:40,364 as we keep trying to keep Voyager warm, 435 00:25:40,408 --> 00:25:42,976 we think that it's when it's cold it fails, 436 00:25:43,019 --> 00:25:44,760 so I'm thinking of a way to bring a heater in 437 00:25:44,804 --> 00:25:46,501 and maybe go off the battery 438 00:25:46,545 --> 00:25:48,329 and and warm up the engine control module 439 00:25:48,372 --> 00:25:51,027 if it ever fails to uh, to start. 440 00:25:51,071 --> 00:25:52,638 Knock on wood, 441 00:25:52,681 --> 00:25:54,204 it's started for the last three weeks, so... 442 00:25:57,599 --> 00:25:59,340 I'm not that mechanically minded, 443 00:25:59,383 --> 00:26:01,342 surprisingly, for a rocket scientist, 444 00:26:01,385 --> 00:26:03,997 but, uh, I certainly had the opportunity. 445 00:26:04,040 --> 00:26:07,217 My dad is incredibly handy, he can fix anything, 446 00:26:07,261 --> 00:26:08,610 and I could have been out with him 447 00:26:08,654 --> 00:26:10,307 learning all this stuff, 448 00:26:10,351 --> 00:26:12,135 but I I was inside practicing the piano. 449 00:26:15,312 --> 00:26:17,314 Music's like a second career. 450 00:26:17,358 --> 00:26:18,664 I'm in six groups. 451 00:26:18,707 --> 00:26:20,274 ♪ I'll never be... 452 00:26:20,317 --> 00:26:21,884 Sometimes it's just running 453 00:26:21,928 --> 00:26:23,625 from one musical rehearsal to the other. 454 00:26:25,801 --> 00:26:27,716 I try to keep them straight. 455 00:26:28,238 --> 00:26:30,023 I just couldn't decide throughout my life, 456 00:26:30,066 --> 00:26:32,199 music or engineering. 457 00:26:32,242 --> 00:26:34,593 I decided just to keep deferring the decision. 458 00:26:35,811 --> 00:26:37,683 I still pinch myself 459 00:26:37,726 --> 00:26:40,294 that these musical dreams of childhood have come true 460 00:26:40,337 --> 00:26:42,949 just as my, uh, JPL dreams came true. 461 00:26:43,602 --> 00:26:47,388 Um, who worked on Voyager in the in the band here? 462 00:26:47,431 --> 00:26:49,390 One, Jeff did. 463 00:26:49,433 --> 00:26:52,088 - No, I didn't. - Everybody's too young, so 464 00:26:53,829 --> 00:26:55,875 My journey to Voyager is a long one. 465 00:26:56,484 --> 00:26:59,792 It began when I was a nerdy kid off in Kansas, 466 00:26:59,835 --> 00:27:01,489 uh, visiting my grandparents. 467 00:27:03,796 --> 00:27:05,232 Thanks a lot. 468 00:27:05,275 --> 00:27:06,668 Uh, can you hear me in the back okay 469 00:27:06,712 --> 00:27:07,843 with the cordless headset mic? 470 00:27:07,887 --> 00:27:09,932 We're good?

01:12:06,757 But we had to tweak things 1221 01:12:06,800 --> 01:12:09,020 more than we would have 1222 01:12:09,063 --> 01:12:11,109 since we were moving the facilities. 1223 01:12:16,941 --> 01:12:18,334 NASA made the room for us 1224 01:12:18,377 --> 01:12:20,031 to go back over to the laboratory. 1225 01:12:21,772 --> 01:12:25,471 We had a lot of things to move, a lot of things to pack. 1226 01:12:25,514 --> 01:12:28,344 We've been there for like, uh, gosh, close to 20 years. 1227 01:12:30,955 --> 01:12:32,826 It's more than just taking your plant 1228 01:12:32,870 --> 01:12:34,741 from one office to the other office. 1229 01:12:35,351 --> 01:12:38,266 It was all the operations hardware got moved, 1230 01:12:38,309 --> 01:12:40,746 got upgraded because it's old, 1231 01:12:40,791 --> 01:12:42,923 so we had to change operating systems. 1232 01:12:43,489 --> 01:12:44,925 We had some nightmares 1233 01:12:44,969 --> 01:12:48,625 where some low-level engineer 1234 01:12:48,668 --> 01:12:51,367 was told to take the network down 1235 01:12:51,410 --> 01:12:55,414 and the whole command system that Voyager uses 1236 01:12:55,458 --> 01:12:58,591 was offline and damaged, 1237 01:12:58,635 --> 01:13:01,246 and it's a bit of the low-tech things 1238 01:13:01,289 --> 01:13:03,030 that, uh, can kill a mission. 1239 01:13:04,989 --> 01:13:06,251 We struggle, you know? 1240 01:13:06,817 --> 01:13:09,950 Different environment, version machines, 1241 01:13:10,690 --> 01:13:14,041 but in all the adjustments, the new computers, 1242 01:13:14,085 --> 01:13:17,915 the new ways of doing things, that keeps me going. 1243 01:13:20,004 --> 01:13:21,092 As you know... 1244 01:13:22,309 --> 01:13:24,225 tragedy in the family happened and... 1245 01:13:25,313 --> 01:13:28,404 right in the middle of, uh, the pandemic. 1246 01:13:33,931 --> 01:13:35,411 She always had issues 1247 01:13:35,454 --> 01:13:38,501 with high blood pressure. 1248 01:13:38,544 --> 01:13:42,243 When I got home around 6:00, I asked my son, 1249 01:13:42,287 --> 01:13:44,463 "Where's your mom?" 1250 01:13:44,507 --> 01:13:47,466 He says, "Well, sh she should be at the office." 1251 01:13:47,510 --> 01:13:49,380 So, I called her office, nothing. 1252 01:13:49,425 --> 01:13:53,298 I asked my son, "Can you go check on her?" 1253 01:13:53,341 --> 01:13:55,735 And he went and checked on her 1254 01:13:55,779 --> 01:13:58,825 and he found her on the floor. 1255 01:13:58,869 --> 01:14:02,612 She had some kind of aneurysm. 1256 01:14:02,655 --> 01:14:05,092 It was not possible to operate. 1257 01:14:06,050 --> 01:14:07,573 But, uh, 1258 01:14:07,617 --> 01:14:11,098 we kept fighting for 17 days and... 1259 01:14:11,142 --> 01:14:13,449 and that's when she passed away, on February 2nd. 1260 01:14:16,843 --> 01:14:19,019 50-plus years together... 1261 01:14:20,412 --> 01:14:21,457 uh... 1262 01:14:22,545 --> 01:14:23,589 yeah. 1263 01:14:28,986 --> 01:14:32,684 I lost a lot of weight, about 17 pounds. 1264 01:14:33,251 --> 01:14:36,384 But, uh, work keeps me busy. 1265 01:14:36,428 --> 01:14:37,473 Uh... 1266 01:14:39,562 --> 01:14:40,780 I always love Voyager. 1267 01:14:45,785 --> 01:14:49,049 It makes me feel that I'm needed someplace. 1268 01:14:50,660 --> 01:14:54,490 That I have the expertise to take Voyager, 1269 01:14:54,532 --> 01:14:56,840 uh, past 2025. 1270 01:14:58,102 --> 01:14:59,277 Maybe longer. 1271 01:14:59,320 --> 01:15:04,369 ♪ 1272 01:15:09,896 --> 01:15:12,856 We did have an initial test last night. 1273 01:15:13,596 --> 01:15:16,163 We expect it to be successful 1274 01:15:16,207 --> 01:15:20,254 and hopefully everything will go back to normal 1275 01:15:20,298 --> 01:15:21,429 beginning of next year. 1276 01:15:25,869 --> 01:15:27,348 As time progresses, 1277 01:15:27,392 --> 01:15:30,047 we're going to do less and less. 1278 01:15:31,396 --> 01:15:34,181 Some would say that there are only eight more commands 1279 01:15:34,704 --> 01:15:36,401 we have to issue on Voyager. 1280 01:15:37,358 --> 01:15:41,362 And those are the ones that gradually turn down 1281 01:15:41,406 --> 01:15:43,016 the power consumption 1282 01:15:43,059 --> 01:15:44,931 until we're to the point 1283 01:15:44,975 --> 01:15:48,282 where we're sitting at 202 watts 1284 01:15:48,326 --> 01:15:50,633 and we can't go any lower. 1285 01:15:51,111 --> 01:15:52,635 The end is coming. 1286 01:15:53,809 --> 01:15:55,550 And the end may take ten years. 1287 01:15:56,639 --> 01:15:58,291 It may take two years, 1288 01:15:58,335 --> 01:16:01,557 we don't really know, but, um, it's coming. 1289 01:16:03,036 --> 01:16:06,126 We're gonna come into the office one day, 1290 01:16:06,170 --> 01:16:08,737 expect to see data from this pass, 1291 01:16:08,781 --> 01:16:09,869 and we won't see it. 1292 01:16:11,392 --> 01:16:14,700 And then we'll try 1293 01:16:14,744 --> 01:16:17,485 and get some other antennas and maybe more antennas. 1294 01:16:18,748 --> 01:16:21,184 Try and really see if we can find a signal. 1295 01:16:21,838 --> 01:16:25,362 And after a week, after a month, 1296 01:16:25,929 --> 01:16:27,844 after three months of looking for it... 1297 01:16:30,673 --> 01:16:32,109 if we still don't hear anything... 1298 01:16:38,289 --> 01:16:42,335 we will declare the mission over. 1299 01:16:42,380 --> 01:16:45,165 And so, billions of miles from Earth, 1300 01:16:45,209 --> 01:16:47,514 the spacecraft, its instruments dead, 1301 01:16:47,559 --> 01:16:49,300 its mission fulfilled, 1302 01:16:49,343 --> 01:16:51,824 may end up in orbit about some distant star. 1303 01:17:12,671 --> 01:17:15,152 So, one of the one of the things that, uh, 1304 01:17:15,195 --> 01:17:16,849 strikes me, uh, 1305 01:17:16,893 --> 01:17:19,243 when I think about Voyager in the early days, 1306 01:17:20,331 --> 01:17:23,160 there was a time when I was a kid... 1307 01:17:24,552 --> 01:17:26,684 and I had a role 1308 01:17:26,728 --> 01:17:31,603 in doing something for the very, very, very first time. 1309 01:17:31,647 --> 01:17:34,344 Voyager is now on a 105-mile high 1310 01:17:34,388 --> 01:17:35,999 parking orbit. 1311 01:17:36,041 --> 01:17:37,348 Heading down over the South Atlantic 1312 01:17:37,391 --> 01:17:38,871 on a trajectory which will... 1313 01:17:38,915 --> 01:17:41,568 As we get to the end of the mission, 1314 01:17:41,612 --> 01:17:43,659 it becomes it's special 1315 01:17:43,702 --> 01:17:45,398 because it's going to be the last day. 1316 01:18:01,198 --> 01:18:03,983 I'm sort of looking back... 1317 01:18:05,637 --> 01:18:08,596 describing how... 1318 01:18:09,989 --> 01:18:11,991 it feels to fly something that's... 1319 01:18:13,427 --> 01:18:17,170 at the time, only a couple of years old, 1320 01:18:18,258 --> 01:18:20,391 but in the end, 1321 01:18:21,392 --> 01:18:22,915 would be 50 years old. 1322 01:18:26,005 --> 01:18:27,180 And... 1323 01:18:29,139 --> 01:18:31,097 what it means to lose them. 1324 01:18:37,234 --> 01:18:40,541 There are things that are left behind 1325 01:18:41,891 --> 01:18:45,721 that are sort of the residue of the work we do. 1326 01:18:46,764 --> 01:18:48,375 The good friends we had. 1327 01:18:49,202 --> 01:18:51,248 The people who worked on Voyager, 1328 01:18:52,335 --> 01:18:55,556 all 1,200 of them... 1329 01:18:59,691 --> 01:19:00,952 mostly gone. 1330 01:19:12,530 --> 01:19:14,314 Well, it's sad because the mission's ending, 1331 01:19:14,358 --> 01:19:16,012 so you're not gonna get the science back, 1332 01:19:16,055 --> 01:19:18,710 but I think it's more related to the people. 1333 01:19:20,190 --> 01:19:23,454 The people will disperse, you won't see them as much. 1334 01:19:24,411 --> 01:19:25,804 It'll be difficult for the people 1335 01:19:25,848 --> 01:19:27,414 who are still working on the project. 1336 01:19:28,675 --> 01:19:30,591 Many of them have worked on the project, 1337 01:19:30,635 --> 01:19:33,898 if not from launch, then shortly after launch. 1338 01:19:33,943 --> 01:19:37,990 So, they've put their whole career on Voyager, 1339 01:19:38,034 --> 01:19:40,123 and so to have Voyager end will be 1340 01:19:40,166 --> 01:19:41,689 it'll be very difficult. 1341 01:19:45,563 --> 01:19:47,434 I know it the day is gonna come. 1342 01:19:48,174 --> 01:19:50,960 This is like when you see your children grow up 1343 01:19:51,003 --> 01:19:52,831 and you kind of you're sad, 1344 01:19:52,875 --> 01:19:55,268 but at the same time, you kind of feel like, uh, 1345 01:19:55,312 --> 01:19:58,358 wow, you know, "We accomplished something." 1346 01:20:00,534 --> 01:20:02,754 When you feel that you've gone the extra mile, 1347 01:20:02,798 --> 01:20:05,539 then I think that you can rest and just... 1348 01:20:07,498 --> 01:20:08,585 let it go. 1349 01:20:12,851 --> 01:20:15,332 We count every day as a blessing, but we've 1350 01:20:15,375 --> 01:20:17,464 we've learned not to bet against the spacecraft too. 1351 01:20:17,508 --> 01:20:21,032 'Cause it always seems to, uh, find that resilient energy 1352 01:20:21,077 --> 01:20:22,992 to keep going and and, uh, 1353 01:20:23,035 --> 01:20:24,907 a large part of that is the team, 1354 01:20:24,950 --> 01:20:27,344 the the the brilliant engineers and scientists I work 1355 01:20:27,387 --> 01:20:29,302 with that have found ways to keep it going 1356 01:20:29,346 --> 01:20:32,130 and delivering top-notch science. 1357 01:20:32,175 --> 01:20:34,873 The technology is something to behold. 1358 01:20:34,916 --> 01:20:36,657 If Las Vegas oddsmakers 1359 01:20:36,701 --> 01:20:38,442 would have had to pay off the optimists 1360 01:20:38,485 --> 01:20:40,139 that honestly felt as though 1361 01:20:40,183 --> 01:20:43,534 this mission would be as successful as it is, 1362 01:20:43,577 --> 01:20:46,362 there would be a few rich people walking around NASA today. 1363 01:20:46,406 --> 01:20:48,234 The fact is, Voyager beat the odds, 1364 01:20:48,278 --> 01:20:50,019 incredible odds, 1365 01:20:50,062 --> 01:20:51,977 and although in any mission of this type 1366 01:20:52,021 --> 01:20:53,761 there must be a certain degree of luck involved, 1367 01:20:53,805 --> 01:20:55,719 the human factor cannot be underestimated. 1368 01:20:57,200 --> 01:21:00,246 I've only worked a couple years on Voyager, 1369 01:21:00,290 --> 01:21:01,769 but I trying to stand 1370 01:21:01,813 --> 01:21:03,119 on the shoulders of those giants, 1371 01:21:03,728 --> 01:21:06,339 the people that toiled away in anonymity 1372 01:21:06,383 --> 01:21:08,341 keeping these these two spacecraft alive. 1373 01:21:09,081 --> 01:21:11,475 Just to be considered, uh, 1374 01:21:11,518 --> 01:21:15,696 you know, a cub scout alongside them. 1375 01:21:15,740 --> 01:21:17,916 Those long term explorers, I'll take it. 1376 01:21:17,960 --> 01:21:19,744 It's an amazing honor and privilege. 1377 01:21:21,572 --> 01:21:23,748 The explorers are the Voyagers. 1378 01:21:24,749 --> 01:21:25,880 Not us. 1379 01:21:27,925 --> 01:21:29,275 We're just the drivers. 1380 01:21:37,630 --> 01:21:39,198 It's like Lewis and Clark. 1381 01:21:40,634 --> 01:21:42,027 They were explorers. 1382 01:21:42,071 --> 01:21:44,987 But let's imagine that they had 1383 01:21:45,030 --> 01:21:46,249 a guardian angel... 1384 01:21:47,511 --> 01:21:48,642 looking after them. 1385 01:21:49,948 --> 01:21:53,559 They were not explorers. They were just guardian angels. 1386 01:22:27,986 --> 01:22:31,207 4-3 Voyager ace. 1387 01:22:31,250 --> 01:22:32,860 Voyager ace, 1388 01:22:32,904 --> 01:22:34,688 station 4-3, I have you. 1389 01:22:35,602 --> 01:22:37,343 I read you the same 1390 01:22:37,387 --> 01:22:41,085 and we have a command uplink with, uh, Voyager 2. 1391 01:22:41,130 --> 01:22:42,348 And I'm ready to copy. 1392 01:22:42,392 --> 01:22:44,698 Please turn command mode on 1393 01:22:44,742 --> 01:22:48,180 at 194900. 1394 01:22:48,224 --> 01:22:52,271 ♪ 1395 01:23:33,225 --> 01:23:40,145 ♪ 103690
