00:00:13,030 --> 00:00:10,960 institutional arrangements in solar 5 00:00:15,110 --> 00:00:13,040 system exploration 6 00:00:17,510 --> 00:00:15,120 we have four papers prison to be 7 00:00:19,269 --> 00:00:17,520 presented by for astute individuals who 8 00:00:21,670 --> 00:00:19,279 will consider relevant issues based on 9 00:00:24,310 --> 00:00:21,680 their experience and their research all 10 00:00:26,150 --> 00:00:24,320 their bios are available to you so i 11 00:00:26,870 --> 00:00:26,160 won't take the time to go through them i 12 00:00:29,669 --> 00:00:26,880 will 13 00:00:32,310 --> 00:00:29,679 just briefly mention we have jim burke 14 00:00:34,150 --> 00:00:32,320 from jpl the legendary jim burke it's 15 00:00:35,670 --> 00:00:34,160 been my pleasure to work with him for 16 00:00:36,950 --> 00:00:35,680 years with the international space 17 00:00:39,670 --> 00:00:36,960 university 18 00:00:42,470 --> 00:00:39,680 john cercosian an operations scientist 19 00:00:44,549 --> 00:00:42,480 at csiro which i looked up in its 20 00:00:48,150 --> 00:00:44,559 commonwealth scientific and industrial 21 00:00:50,549 --> 00:00:48,160 research organization from australia 22 00:00:52,549 --> 00:00:50,559 michael neufeld museum curator in the 23 00:00:56,229 --> 00:00:52,559 space history division at the national 24 00:00:58,709 --> 00:00:56,239 air and space museum and peter markovsky 25 00:01:01,349 --> 00:00:58,719 a phd candidate in history of science at 26 00:01:03,189 --> 00:01:01,359 the university of oklahoma 27 00:01:05,429 --> 00:01:03,199 the issues they will be considering are 28 00:01:07,350 --> 00:01:05,439 several institutional management for 29 00:01:09,350 --> 00:01:07,360 example will be considered as will 30 00:01:11,990 --> 00:01:09,360 institutional focus 31 00:01:14,070 --> 00:01:12,000 how management issues arrangements and 32 00:01:15,990 --> 00:01:14,080 focus can affect the ability to execute 33 00:01:18,469 --> 00:01:16,000 a highly sophisticated 34 00:01:20,310 --> 00:01:18,479 science and engineering pro program and 35 00:01:21,990 --> 00:01:20,320 we've already been hearing about that 36 00:01:25,030 --> 00:01:22,000 this morning through different 37 00:01:27,030 --> 00:01:25,040 international collaboration uh examples 38 00:01:29,109 --> 00:01:27,040 and these papers will consider and go 39 00:01:30,550 --> 00:01:29,119 into depth on those issues including 40 00:01:31,990 --> 00:01:30,560 international collaboration the 41 00:01:33,910 --> 00:01:32,000 complexity 42 00:01:36,230 --> 00:01:33,920 and the potential that is added by 43 00:01:37,990 --> 00:01:36,240 expanding missions beyond national or 44 00:01:39,030 --> 00:01:38,000 extending missions beyond national 45 00:01:41,270 --> 00:01:39,040 borders 46 00:01:43,350 --> 00:01:41,280 and clearly the complexity expansion is 47 00:01:44,870 --> 00:01:43,360 across the board not just 48 00:01:46,950 --> 00:01:44,880 with the science and engineering 49 00:01:48,389 --> 00:01:46,960 considerations but with the political 50 00:01:50,310 --> 00:01:48,399 and legal 51 00:01:52,069 --> 00:01:50,320 one point that has really fascinated me 52 00:01:54,630 --> 00:01:52,079 over the years as an 53 00:01:57,270 --> 00:01:54,640 observer and analyst of these 54 00:02:00,550 --> 00:01:57,280 institutional arrangements 55 00:02:02,550 --> 00:02:00,560 is the role and perhaps changing role of 56 00:02:05,030 --> 00:02:02,560 the program manager 57 00:02:06,789 --> 00:02:05,040 i'll give fair warning now to the 58 00:02:09,109 --> 00:02:06,799 panelists that that'll be a question i 59 00:02:10,630 --> 00:02:09,119 will be raising to them and i hope you 60 00:02:12,949 --> 00:02:10,640 the audience will be noting your 61 00:02:15,510 --> 00:02:12,959 questions that they can 62 00:02:17,589 --> 00:02:15,520 address as well we'll follow the same 63 00:02:20,070 --> 00:02:17,599 format as we have 64 00:02:22,390 --> 00:02:20,080 already 20 minute presentations five 65 00:02:24,390 --> 00:02:22,400 minutes of q a and then the panel will 66 00:02:26,630 --> 00:02:24,400 assemble at the end 67 00:02:28,630 --> 00:02:26,640 so with that i would like to introduce 68 00:02:31,430 --> 00:02:28,640 jim burke on to talk about the 69 00:02:33,589 --> 00:02:31,440 foundations of solar system exploration 70 00:02:41,509 --> 00:02:33,599 at jpl how the first mariners and 71 00:02:46,390 --> 00:02:43,589 thank you joan i'd like to begin by 72 00:02:47,830 --> 00:02:46,400 giving you a little background on the 73 00:02:50,790 --> 00:02:47,840 co-author 74 00:02:52,869 --> 00:02:50,800 and my successor as ranger project 75 00:02:55,350 --> 00:02:52,879 manager bud schermeier 76 00:02:58,390 --> 00:02:55,360 many of you of course know him from his 77 00:03:00,390 --> 00:02:58,400 distinguished later uh reputation at jpl 78 00:03:03,910 --> 00:03:00,400 as project manager of 79 00:03:06,070 --> 00:03:03,920 various projects mariner 6 and 7 and uh 80 00:03:07,990 --> 00:03:06,080 the voyagers as of when they were 81 00:03:10,149 --> 00:03:08,000 launched he was one of the 82 00:03:13,270 --> 00:03:10,159 first of a long succession of uh 83 00:03:14,550 --> 00:03:13,280 excellent project managers on voyager 84 00:03:16,070 --> 00:03:14,560 but 85 00:03:17,589 --> 00:03:16,080 what i'd like to do here is take a 86 00:03:19,750 --> 00:03:17,599 couple minutes to tell you a little bit 87 00:03:23,509 --> 00:03:19,760 about the earlier part of 88 00:03:26,309 --> 00:03:23,519 his life he and i graduated from caltech 89 00:03:27,990 --> 00:03:26,319 after meeting each other as freshmen 90 00:03:32,630 --> 00:03:28,000 70 years ago 91 00:03:38,869 --> 00:03:34,149 and 92 00:03:42,470 --> 00:03:38,879 of course enjoyed all the 93 00:03:44,550 --> 00:03:42,480 southern california recreations soaring 94 00:03:46,630 --> 00:03:44,560 sailing skiing 95 00:03:48,309 --> 00:03:46,640 surfing whatever else there is that 96 00:03:50,710 --> 00:03:48,319 doesn't begin with s 97 00:03:52,710 --> 00:03:50,720 uh he brought me down off the mountain 98 00:03:55,670 --> 00:03:52,720 with a broken leg 99 00:04:01,509 --> 00:03:59,910 so we know each other pretty well and uh 100 00:04:04,710 --> 00:04:01,519 in any case 101 00:04:07,990 --> 00:04:04,720 it was my very good fortune to have 102 00:04:09,990 --> 00:04:08,000 him in position as manager of jpl's 103 00:04:12,149 --> 00:04:10,000 systems division which is where all the 104 00:04:13,429 --> 00:04:12,159 subsystems get to try to work with each 105 00:04:15,429 --> 00:04:13,439 other 106 00:04:16,789 --> 00:04:15,439 that's what he was doing 107 00:04:18,789 --> 00:04:16,799 while i was 108 00:04:19,830 --> 00:04:18,799 being the first project manager of 109 00:04:22,790 --> 00:04:19,840 ranger 110 00:04:27,670 --> 00:04:22,800 but our experience at jpl went way back 111 00:04:33,030 --> 00:04:30,390 so that by the time ranger came along we 112 00:04:35,510 --> 00:04:33,040 both had been working at jpl for more 113 00:04:36,629 --> 00:04:35,520 than 10 years 114 00:04:38,629 --> 00:04:36,639 and 115 00:04:40,310 --> 00:04:38,639 one part of what i'm 116 00:04:44,790 --> 00:04:40,320 going to tell you from 117 00:04:47,030 --> 00:04:44,800 here on uh is how there was a collision 118 00:04:50,230 --> 00:04:47,040 between us and everybody else involved 119 00:04:52,710 --> 00:04:50,240 in the project uh all the way up to 120 00:04:54,550 --> 00:04:52,720 congress and later in the game 121 00:04:56,469 --> 00:04:54,560 uh because we really thought we knew 122 00:04:58,390 --> 00:04:56,479 what we were doing we were experienced 123 00:05:01,830 --> 00:04:58,400 both of us were experienced project 124 00:05:04,870 --> 00:05:01,840 managers under the army and we knew how 125 00:05:06,390 --> 00:05:04,880 to do what we were doing 126 00:05:08,390 --> 00:05:06,400 ranger 127 00:05:10,550 --> 00:05:08,400 presented us with 128 00:05:11,990 --> 00:05:10,560 a more complicated and 129 00:05:15,670 --> 00:05:12,000 bigger 130 00:05:17,830 --> 00:05:15,680 project to do uh but not one that was in 131 00:05:20,070 --> 00:05:17,840 different in any essential way from the 132 00:05:21,270 --> 00:05:20,080 things we'd been doing before 133 00:05:24,070 --> 00:05:21,280 therefore 134 00:05:25,909 --> 00:05:24,080 there was a definite collision between 135 00:05:27,430 --> 00:05:25,919 us 136 00:05:28,790 --> 00:05:27,440 and 137 00:05:29,990 --> 00:05:28,800 our 138 00:05:32,710 --> 00:05:30,000 leaders 139 00:05:34,390 --> 00:05:32,720 once we were transferred out of the army 140 00:05:35,990 --> 00:05:34,400 and into nasa 141 00:05:38,150 --> 00:05:36,000 because nasa had a whole lot of 142 00:05:39,990 --> 00:05:38,160 engineers who were just as experienced 143 00:05:41,909 --> 00:05:40,000 and just as smart as us 144 00:05:43,909 --> 00:05:41,919 and it took us a while to realize that 145 00:05:45,590 --> 00:05:43,919 they were our bosses 146 00:05:46,469 --> 00:05:45,600 well that's a little bit the theme of 147 00:05:48,070 --> 00:05:46,479 this 148 00:05:51,189 --> 00:05:48,080 presentation 149 00:05:55,189 --> 00:05:53,270 no i don't have a screen well 150 00:05:57,590 --> 00:05:55,199 no i can't read it up there i'll have to 151 00:05:59,990 --> 00:05:57,600 read it here sorry about that 152 00:06:03,670 --> 00:06:02,150 jpl 153 00:06:05,430 --> 00:06:03,680 of course 154 00:06:08,550 --> 00:06:05,440 launched the first earth satellites 155 00:06:10,629 --> 00:06:08,560 explorer one four five 156 00:06:13,270 --> 00:06:10,639 but uh 157 00:06:14,790 --> 00:06:13,280 quickly it was determined that earth 158 00:06:17,029 --> 00:06:14,800 satellites were going to be a big 159 00:06:20,150 --> 00:06:17,039 business in a crowded field 160 00:06:22,070 --> 00:06:20,160 and we as a university laboratory 161 00:06:24,710 --> 00:06:22,080 shouldn't really 162 00:06:25,749 --> 00:06:24,720 be in that field so 163 00:06:27,350 --> 00:06:25,759 we 164 00:06:30,790 --> 00:06:27,360 chose to go 165 00:06:32,390 --> 00:06:30,800 beyond low earth orbit first target 166 00:06:33,430 --> 00:06:32,400 being 167 00:06:35,670 --> 00:06:33,440 mars 168 00:06:39,510 --> 00:06:35,680 for the 1960 169 00:06:41,430 --> 00:06:39,520 opposition uh the 1960 launch window 170 00:06:44,230 --> 00:06:41,440 uh which was the first time in human 171 00:06:45,909 --> 00:06:44,240 history that something could be launched 172 00:06:49,029 --> 00:06:45,919 to mars 173 00:06:50,950 --> 00:06:49,039 so that was the objective initially 174 00:06:54,710 --> 00:06:50,960 retreated back from that driven by 175 00:06:57,589 --> 00:06:54,720 circumstances to the moon 176 00:07:00,469 --> 00:06:57,599 that was the process as of 177 00:07:02,390 --> 00:07:00,479 1958 178 00:07:06,070 --> 00:07:02,400 okay the von braun team 179 00:07:06,950 --> 00:07:06,080 uh very experienced of course uh 180 00:07:09,510 --> 00:07:06,960 we 181 00:07:10,950 --> 00:07:09,520 had to go through quite a transition 182 00:07:12,629 --> 00:07:10,960 with them 183 00:07:14,469 --> 00:07:12,639 because they ended up in a very 184 00:07:17,270 --> 00:07:14,479 anomalous position 185 00:07:19,350 --> 00:07:17,280 once nasa was formed 186 00:07:22,309 --> 00:07:19,360 the phone brown people 187 00:07:25,110 --> 00:07:22,319 were nasa's agent for procuring launch 188 00:07:27,270 --> 00:07:25,120 services from the air force 189 00:07:29,749 --> 00:07:27,280 if you can find a more difficult 190 00:07:31,350 --> 00:07:29,759 situation for somebody 191 00:07:33,749 --> 00:07:31,360 that's where they were 192 00:07:35,670 --> 00:07:33,759 and it's to their great credit that 193 00:07:38,870 --> 00:07:35,680 individuals in 194 00:07:40,950 --> 00:07:38,880 both the air force and the army 195 00:07:43,189 --> 00:07:40,960 saw to it that in spite of all the 196 00:07:45,510 --> 00:07:43,199 institutional rivalries and other things 197 00:07:47,510 --> 00:07:45,520 that were happening at the time 198 00:07:50,950 --> 00:07:47,520 they managed to pull it off they got us 199 00:07:54,950 --> 00:07:53,029 tremendous confusion not just about 200 00:07:56,790 --> 00:07:54,960 launch vehicles but really about 201 00:07:59,510 --> 00:07:56,800 everything 202 00:08:01,270 --> 00:07:59,520 as to who was going to do what 203 00:08:02,710 --> 00:08:01,280 but uh 204 00:08:06,869 --> 00:08:02,720 rather quickly 205 00:08:09,990 --> 00:08:06,879 in 1958 and 59 206 00:08:13,029 --> 00:08:10,000 we discovered that we just couldn't do 207 00:08:15,270 --> 00:08:13,039 that mars launch window it was way 208 00:08:16,070 --> 00:08:15,280 beyond anything we could logically hope 209 00:08:19,029 --> 00:08:16,080 to 210 00:08:20,950 --> 00:08:19,039 so the big mariner 211 00:08:23,110 --> 00:08:20,960 called mariner a 212 00:08:25,430 --> 00:08:23,120 that was planned for that mission 213 00:08:28,869 --> 00:08:25,440 was abandoned and 214 00:08:31,189 --> 00:08:28,879 uh was decided to build a mariner for 215 00:08:33,110 --> 00:08:31,199 venus in 1962 216 00:08:35,990 --> 00:08:33,120 a couple of them 217 00:08:37,190 --> 00:08:36,000 that would be derived from the smaller 218 00:08:39,269 --> 00:08:37,200 ranger 219 00:08:40,709 --> 00:08:39,279 lunar spacecraft 220 00:08:42,870 --> 00:08:40,719 that we were building 221 00:08:46,070 --> 00:08:42,880 ranger already had 222 00:08:48,470 --> 00:08:46,080 solar mantles solar panels and a high 223 00:08:50,550 --> 00:08:48,480 gain antenna because those are features 224 00:08:52,389 --> 00:08:50,560 that you have to have for interplanetary 225 00:08:53,430 --> 00:08:52,399 missions you don't need them for the 226 00:08:56,070 --> 00:08:53,440 moon 227 00:08:58,710 --> 00:08:56,080 but we we had them on ranger because we 228 00:09:01,509 --> 00:08:58,720 visualized it as a precursor to 229 00:09:03,829 --> 00:09:01,519 planetary missions three-axis attitude 230 00:09:05,190 --> 00:09:03,839 control pointing an antenna getting 231 00:09:06,550 --> 00:09:05,200 solar power 232 00:09:09,430 --> 00:09:06,560 and 233 00:09:10,790 --> 00:09:09,440 being execute a being able to execute a 234 00:09:13,350 --> 00:09:10,800 mid-course 235 00:09:14,870 --> 00:09:13,360 maneuver trajectory correction those 236 00:09:17,350 --> 00:09:14,880 were the features 237 00:09:19,110 --> 00:09:17,360 that had to be on the mariner so they 238 00:09:21,430 --> 00:09:19,120 were on the ranger 239 00:09:25,350 --> 00:09:21,440 and the mariner became to be called 240 00:09:27,590 --> 00:09:25,360 ranger uh mariner r derived from ranger 241 00:09:30,630 --> 00:09:27,600 okay 242 00:09:33,670 --> 00:09:30,640 mariner a became mariner r 243 00:09:37,509 --> 00:09:33,680 okay the air force and our huntsville 244 00:09:40,070 --> 00:09:37,519 friends got us the atlas agena 245 00:09:43,910 --> 00:09:40,080 the deep space net and space 246 00:09:46,790 --> 00:09:43,920 flight operations facility necessary for 247 00:09:57,750 --> 00:09:46,800 both lunar and planetary missions 248 00:10:03,269 --> 00:10:01,110 common bus variable payloads 249 00:10:05,430 --> 00:10:03,279 everything you see on this slide was an 250 00:10:07,030 --> 00:10:05,440 attempt by us 251 00:10:08,870 --> 00:10:07,040 to try to 252 00:10:10,630 --> 00:10:08,880 meet the requirement of building 253 00:10:13,670 --> 00:10:10,640 reliability 254 00:10:15,269 --> 00:10:13,680 through successive operations 255 00:10:16,310 --> 00:10:15,279 and still meeting 256 00:10:18,550 --> 00:10:16,320 the 257 00:10:20,230 --> 00:10:18,560 difficult demands of planetary missions 258 00:10:22,230 --> 00:10:20,240 where you can't change the schedule 259 00:10:23,269 --> 00:10:22,240 unless you're prepared to slip it for 260 00:10:25,910 --> 00:10:23,279 years 261 00:10:28,389 --> 00:10:25,920 uh as in fact did happen with curiosity 262 00:10:32,949 --> 00:10:28,399 the big rover 263 00:10:38,069 --> 00:10:35,750 science on every flight 264 00:10:41,350 --> 00:10:38,079 i had what now seems a very peculiar 265 00:10:43,750 --> 00:10:41,360 attitude about science 266 00:10:45,670 --> 00:10:43,760 i insisted that every flight carry 267 00:10:47,910 --> 00:10:45,680 scientific instruments 268 00:10:49,190 --> 00:10:47,920 for two reasons 269 00:10:51,190 --> 00:10:49,200 one 270 00:10:53,350 --> 00:10:51,200 we didn't know which flight or flights 271 00:10:54,630 --> 00:10:53,360 might succeed 272 00:10:56,710 --> 00:10:54,640 two 273 00:10:58,630 --> 00:10:56,720 engineering development of science 274 00:11:01,190 --> 00:10:58,640 instruments in flight 275 00:11:04,230 --> 00:11:01,200 is as important as that of any other 276 00:11:06,389 --> 00:11:04,240 subsystem on the spacecraft 277 00:11:08,630 --> 00:11:06,399 and i 278 00:11:11,269 --> 00:11:08,640 simply thought it's up to the project 279 00:11:13,990 --> 00:11:11,279 manager to figure out after receiving 280 00:11:15,750 --> 00:11:14,000 advice from scientists and comparing 281 00:11:17,030 --> 00:11:15,760 that with what you can do what you can 282 00:11:18,949 --> 00:11:17,040 accommodate 283 00:11:20,949 --> 00:11:18,959 then i'll tell the scientists which of 284 00:11:23,829 --> 00:11:20,959 them get to come and which other ones 285 00:11:25,670 --> 00:11:23,839 have to wait for another launch 286 00:11:27,590 --> 00:11:25,680 can you imagine a viewpoint more 287 00:11:28,949 --> 00:11:27,600 different from 288 00:11:31,190 --> 00:11:28,959 that of 289 00:11:32,949 --> 00:11:31,200 first science is the objective of the 290 00:11:34,710 --> 00:11:32,959 mission come on guys 291 00:11:36,310 --> 00:11:34,720 two 292 00:11:38,790 --> 00:11:36,320 there's a whole structure out there of 293 00:11:40,150 --> 00:11:38,800 scientific advisory committees nasa and 294 00:11:42,230 --> 00:11:40,160 this and that 295 00:11:44,069 --> 00:11:42,240 project manager simply has to sit and 296 00:11:45,590 --> 00:11:44,079 watch all of that happen and then deal 297 00:11:46,470 --> 00:11:45,600 with the result 298 00:11:55,110 --> 00:11:46,480 well 299 00:11:59,910 --> 00:11:58,069 october 1960 i was appointed 300 00:12:02,790 --> 00:11:59,920 project manager 301 00:12:05,269 --> 00:12:02,800 on the 10th of october uh 302 00:12:07,350 --> 00:12:05,279 big rocket takes off 303 00:12:09,509 --> 00:12:07,360 it was the 304 00:12:11,670 --> 00:12:09,519 classic old original one except the 305 00:12:14,069 --> 00:12:11,680 upper stages 306 00:12:16,230 --> 00:12:14,079 weighed more than 30 tons and we watched 307 00:12:18,069 --> 00:12:16,240 the very slow acceleration of that and 308 00:12:18,870 --> 00:12:18,079 thought oh my goodness what is this 309 00:12:20,389 --> 00:12:18,880 thing 310 00:12:22,470 --> 00:12:20,399 then on the second 311 00:12:25,350 --> 00:12:22,480 one on the 14th 312 00:12:27,590 --> 00:12:25,360 of october uh our telemetry was good 313 00:12:30,069 --> 00:12:27,600 enough to show that it had four big engi 314 00:12:31,829 --> 00:12:30,079 big boosters going off like that 315 00:12:33,269 --> 00:12:31,839 so that was when we first began to 316 00:12:37,030 --> 00:12:33,279 understand 317 00:12:39,990 --> 00:12:37,040 uh what the malnea configuration 318 00:12:43,030 --> 00:12:40,000 of the soviet launch vehicle 319 00:12:47,829 --> 00:12:44,949 uh when president kennedy was 320 00:12:50,150 --> 00:12:47,839 inaugurated he gave a talk that was very 321 00:12:52,629 --> 00:12:50,160 largely about the contest between 322 00:12:55,430 --> 00:12:52,639 american values and the 323 00:12:57,269 --> 00:12:55,440 subversive and uh threatening 324 00:12:59,670 --> 00:12:57,279 emanations that were coming out of the 325 00:13:01,750 --> 00:12:59,680 ussr 326 00:13:03,190 --> 00:13:01,760 on the 4th and 12th of february as you 327 00:13:05,190 --> 00:13:03,200 heard this morning 328 00:13:08,870 --> 00:13:05,200 they got two launches off and the second 329 00:13:10,710 --> 00:13:08,880 one sent the nero one on its way 330 00:13:13,110 --> 00:13:10,720 then yuri gagarin 331 00:13:14,069 --> 00:13:13,120 kennedy announced apollo 332 00:13:17,509 --> 00:13:14,079 uh 333 00:13:19,670 --> 00:13:17,519 if you can imagine a more 334 00:13:21,030 --> 00:13:19,680 propulsive environment than the one we 335 00:13:24,069 --> 00:13:21,040 were in 336 00:13:27,190 --> 00:13:24,079 to get ranger one and two going uh 337 00:13:31,670 --> 00:13:27,200 we had a lot of uh pressure on us 338 00:13:33,430 --> 00:13:31,680 much of it provided by ourselves uh and 339 00:13:38,710 --> 00:13:33,440 we you know we really wanted to get 340 00:13:38,720 --> 00:13:45,509 things moved fast 341 00:13:51,430 --> 00:13:49,110 i skipped over a whole lot of trouble 342 00:13:53,030 --> 00:13:51,440 originally when nasa 343 00:13:55,189 --> 00:13:53,040 first 344 00:13:56,629 --> 00:13:55,199 when we and the germans were transferred 345 00:13:59,189 --> 00:13:56,639 into nasa 346 00:14:02,629 --> 00:13:59,199 we already had a plan 347 00:14:04,550 --> 00:14:02,639 for upper stages on the atlas but they 348 00:14:06,790 --> 00:14:04,560 were not the right ones 349 00:14:08,949 --> 00:14:06,800 the air force agena was the right upper 350 00:14:10,230 --> 00:14:08,959 stage to use but it took oops how did 351 00:14:14,310 --> 00:14:10,240 that happen 352 00:14:14,320 --> 00:14:19,829 i went back too far sorry okay 353 00:14:23,350 --> 00:14:21,670 oh 354 00:14:26,069 --> 00:14:23,360 what happened 355 00:14:27,990 --> 00:14:26,079 okay never mind they uh 356 00:14:31,269 --> 00:14:28,000 something about the launch vehicles was 357 00:14:36,389 --> 00:14:31,279 on the slide that is now missing 358 00:14:41,269 --> 00:14:39,110 marshall was placed in a very tough 359 00:14:43,670 --> 00:14:41,279 position but we did 360 00:14:45,910 --> 00:14:43,680 end up again because of the dedication 361 00:14:46,870 --> 00:14:45,920 of individuals in the agencies who put 362 00:14:47,829 --> 00:14:46,880 our 363 00:14:50,710 --> 00:14:47,839 needs 364 00:14:53,030 --> 00:14:50,720 above the interagency disputes that were 365 00:14:54,629 --> 00:14:53,040 all going on then 366 00:14:58,069 --> 00:14:54,639 we got 367 00:15:00,389 --> 00:14:58,079 the launch vehicles that we needed 368 00:15:01,590 --> 00:15:00,399 i told you about how we didn't 369 00:15:03,910 --> 00:15:01,600 really 370 00:15:05,910 --> 00:15:03,920 like being jerked around by people who 371 00:15:07,750 --> 00:15:05,920 were our essential colleagues 372 00:15:10,550 --> 00:15:07,760 professionally and suddenly turned out 373 00:15:12,550 --> 00:15:10,560 to be from nasa a new agency that we'd 374 00:15:15,110 --> 00:15:12,560 never heard of and they were they were 375 00:15:18,069 --> 00:15:15,120 in charge 376 00:15:21,509 --> 00:15:18,079 our lunar scientists 377 00:15:24,550 --> 00:15:21,519 were the leaders in the profession 378 00:15:29,269 --> 00:15:27,430 gamma ray spectrometer 379 00:15:31,269 --> 00:15:29,279 geophysics 380 00:15:32,749 --> 00:15:31,279 seismometer 381 00:15:35,110 --> 00:15:32,759 and 382 00:15:37,110 --> 00:15:35,120 geomorphology the television 383 00:15:39,590 --> 00:15:37,120 those were the instruments on the lunar 384 00:15:40,550 --> 00:15:39,600 rangers and the scientists in charge of 385 00:15:42,870 --> 00:15:40,560 those 386 00:15:45,030 --> 00:15:42,880 did not give us any trouble 387 00:15:47,749 --> 00:15:45,040 they really did a tremendous job and 388 00:15:49,670 --> 00:15:47,759 they are famous for it they were already 389 00:15:52,150 --> 00:15:49,680 famous for their in their own 390 00:15:54,230 --> 00:15:52,160 professions of course 391 00:15:55,509 --> 00:15:54,240 we had a problem with non-lunar 392 00:15:57,430 --> 00:15:55,519 scientists 393 00:16:01,030 --> 00:15:57,440 space physics 394 00:16:02,710 --> 00:16:01,040 uh and i'll get to that a little later 395 00:16:05,829 --> 00:16:02,720 okay and 396 00:16:07,110 --> 00:16:05,839 we had a sort of a philosophical problem 397 00:16:09,509 --> 00:16:07,120 with 398 00:16:11,829 --> 00:16:09,519 not the lunar scientists they were fine 399 00:16:14,230 --> 00:16:11,839 they were on board they followed our 400 00:16:17,590 --> 00:16:14,240 schedule 401 00:16:19,590 --> 00:16:17,600 ranger one and two were planned as test 402 00:16:21,030 --> 00:16:19,600 flights not aimed at the moon but to 403 00:16:22,389 --> 00:16:21,040 have a high enough 404 00:16:24,629 --> 00:16:22,399 apogee 405 00:16:26,949 --> 00:16:24,639 that they would take the spacecraft out 406 00:16:28,470 --> 00:16:26,959 to where it could acquire the sun and 407 00:16:30,949 --> 00:16:28,480 earth references 408 00:16:33,269 --> 00:16:30,959 and since it was going to do that out in 409 00:16:34,310 --> 00:16:33,279 the magnetosphere it might as well have 410 00:16:36,790 --> 00:16:34,320 some 411 00:16:40,069 --> 00:16:36,800 space physics instruments on board it 412 00:16:42,790 --> 00:16:40,079 had an excellent payload designed by the 413 00:16:45,030 --> 00:16:42,800 prominent space physicists of the day 414 00:16:47,910 --> 00:16:45,040 plus an ultraviolet telescope looking 415 00:16:49,829 --> 00:16:47,920 back at the earth's hydrogen corona 416 00:16:52,389 --> 00:16:49,839 three four and five i told you about 417 00:16:54,069 --> 00:16:52,399 their instruments and on ranger six to 418 00:16:58,710 --> 00:16:54,079 nine the 419 00:17:01,990 --> 00:16:58,720 objective was reduced to just television 420 00:17:03,590 --> 00:17:02,000 now here's the example of the bus 421 00:17:06,630 --> 00:17:03,600 with one of the several different 422 00:17:11,029 --> 00:17:06,640 payloads the bus is hexagonal because of 423 00:17:13,750 --> 00:17:11,039 a vanished upper stage configuration 424 00:17:16,309 --> 00:17:13,760 so it was adapted to the agena 425 00:17:18,390 --> 00:17:16,319 the tower on the top has the space 426 00:17:21,270 --> 00:17:18,400 physics instruments and at the very top 427 00:17:24,309 --> 00:17:21,280 the omnidirectional antenna 428 00:17:29,830 --> 00:17:24,319 so that was the configuration of rangers 429 00:17:35,669 --> 00:17:32,870 range of one and two because of uh genia 430 00:17:37,669 --> 00:17:35,679 upper stage troubles never got to their 431 00:17:41,190 --> 00:17:37,679 high apogee orbits 432 00:17:44,150 --> 00:17:41,200 they were stranded in low earth orbit 433 00:17:49,190 --> 00:17:46,630 they the spacecraft appeared to be okay 434 00:17:51,750 --> 00:17:49,200 as far as you could tell in that orbit 435 00:17:54,789 --> 00:17:51,760 a ranger three we had a spacecraft that 436 00:17:57,029 --> 00:17:54,799 was fine it was injected the atlas had a 437 00:17:59,430 --> 00:17:57,039 guidance error but the ranger acquired 438 00:18:00,549 --> 00:17:59,440 the sun on earth and began to do what it 439 00:18:02,230 --> 00:18:00,559 should do 440 00:18:04,630 --> 00:18:02,240 but then when the mid-course maneuver 441 00:18:06,870 --> 00:18:04,640 happened one vector was pointed the 442 00:18:08,870 --> 00:18:06,880 wrong way there had been a double sign 443 00:18:12,150 --> 00:18:08,880 inversion between the spacecraft and the 444 00:18:13,830 --> 00:18:12,160 ground equipment so it missed the moon 445 00:18:16,630 --> 00:18:13,840 range of four 446 00:18:17,990 --> 00:18:16,640 something got across a couple of pins 447 00:18:20,390 --> 00:18:18,000 between 448 00:18:22,630 --> 00:18:20,400 the agena when the when the spacecraft 449 00:18:25,029 --> 00:18:22,640 came away from the agena something 450 00:18:27,590 --> 00:18:25,039 shorted out the ranger 451 00:18:29,590 --> 00:18:27,600 if it had had the female side of the 452 00:18:32,150 --> 00:18:29,600 separation connector that probably 453 00:18:34,150 --> 00:18:32,160 wouldn't have happened 454 00:18:36,870 --> 00:18:34,160 on ranger five i'll show you a picture 455 00:18:39,750 --> 00:18:36,880 of that one a ranger six 456 00:18:42,470 --> 00:18:39,760 this is after i had been replaced as 457 00:18:44,390 --> 00:18:42,480 project manager by bud shermeyer and 458 00:18:45,750 --> 00:18:44,400 i'll tell you more about that later but 459 00:18:47,510 --> 00:18:45,760 here's this 460 00:18:51,350 --> 00:18:47,520 brief version of the story when the 461 00:18:53,750 --> 00:18:51,360 atlas staged its first stage engines off 462 00:18:57,430 --> 00:18:53,760 a plasma cloud enveloped the vehicle and 463 00:19:05,029 --> 00:18:57,440 shorted out the television 464 00:19:09,430 --> 00:19:07,190 this is the configuration of the lunar 465 00:19:10,549 --> 00:19:09,440 ones with the seismometer ball at the 466 00:19:12,870 --> 00:19:10,559 top 467 00:19:13,909 --> 00:19:12,880 and the gamma ray spectrometer out on a 468 00:19:20,549 --> 00:19:13,919 boom 469 00:19:28,950 --> 00:19:22,710 i see i seem to keep 470 00:19:34,230 --> 00:19:30,950 well okay 471 00:19:38,470 --> 00:19:36,789 power switching and logic unit in range 472 00:19:40,630 --> 00:19:38,480 of ranger 5 473 00:19:43,830 --> 00:19:40,640 proof test model of it shows you 474 00:19:46,150 --> 00:19:43,840 something about our packaging 475 00:19:49,110 --> 00:19:46,160 people look at jpl's packaging and they 476 00:19:51,110 --> 00:19:49,120 say hey those look like locomotive parts 477 00:19:53,029 --> 00:19:51,120 well we found out they have to look like 478 00:19:55,110 --> 00:19:53,039 locomotive parts if you don't want to 479 00:19:57,510 --> 00:19:55,120 amplify vibrations from the launch 480 00:19:59,990 --> 00:19:57,520 vehicle etc 481 00:20:03,029 --> 00:20:00,000 and that's why our packages look the way 482 00:20:07,110 --> 00:20:04,870 a backside of this 483 00:20:08,310 --> 00:20:07,120 little item you see the arrow pointing 484 00:20:11,350 --> 00:20:08,320 there 485 00:20:13,990 --> 00:20:11,360 uh that screw got warm and that hit us 486 00:20:16,070 --> 00:20:14,000 in we had a good spacecraft again it had 487 00:20:18,310 --> 00:20:16,080 acquired the sun on earth was on its way 488 00:20:19,270 --> 00:20:18,320 to the moon this time atlas regina was 489 00:20:21,110 --> 00:20:19,280 okay 490 00:20:24,870 --> 00:20:21,120 fine 491 00:20:24,880 --> 00:20:29,470 we went to the ranger 492 00:20:37,909 --> 00:20:33,110 6789 configuration with just television 493 00:20:42,870 --> 00:20:39,590 okay 494 00:20:47,190 --> 00:20:42,880 that's what i'm here to tell you 495 00:20:49,990 --> 00:20:47,200 robotic sp deep space exploration 496 00:20:52,230 --> 00:20:50,000 demands extreme attention to risk and 497 00:20:53,750 --> 00:20:52,240 even then 498 00:20:57,430 --> 00:20:53,760 you don't always 499 00:21:01,750 --> 00:20:59,510 technical risks all the ones in the 500 00:21:03,669 --> 00:21:01,760 ranger both in the launch vehicles and 501 00:21:07,510 --> 00:21:03,679 the spacecraft 502 00:21:10,470 --> 00:21:07,520 the failures were at interfaces 503 00:21:12,950 --> 00:21:10,480 management risks i guess i don't need to 504 00:21:14,230 --> 00:21:12,960 go too much into that 505 00:21:16,789 --> 00:21:14,240 but 506 00:21:17,909 --> 00:21:16,799 after ranger 507 00:21:21,270 --> 00:21:17,919 five 508 00:21:23,350 --> 00:21:21,280 uh the project capsized and 509 00:21:25,669 --> 00:21:23,360 schermer replaced me 510 00:21:28,830 --> 00:21:25,679 then he had the failure of ranger six 511 00:21:31,430 --> 00:21:28,840 which took it all the way up to congress 512 00:21:32,470 --> 00:21:31,440 uh enormous 513 00:21:33,750 --> 00:21:32,480 trouble 514 00:21:37,110 --> 00:21:33,760 and 515 00:21:39,029 --> 00:21:37,120 everything was focused on the rca camera 516 00:21:41,350 --> 00:21:39,039 payload 517 00:21:42,789 --> 00:21:41,360 while in fact 518 00:21:45,270 --> 00:21:42,799 the failure 519 00:21:48,310 --> 00:21:45,280 happened during the atlas booster 520 00:21:52,789 --> 00:21:48,320 staging back during ascent 521 00:21:55,590 --> 00:21:52,799 so a big long failure investigation 522 00:21:58,630 --> 00:21:55,600 entirely focused on 523 00:22:00,549 --> 00:21:58,640 the place where the failure didn't occur 524 00:22:02,870 --> 00:22:00,559 and we may never have known about the 525 00:22:05,190 --> 00:22:02,880 cause of that failure had not a solar 526 00:22:07,909 --> 00:22:05,200 physicist among us 527 00:22:10,789 --> 00:22:07,919 continued to persist in looking into it 528 00:22:12,870 --> 00:22:10,799 and investigating all the records and he 529 00:22:13,990 --> 00:22:12,880 finally decided he had a convincing 530 00:22:16,630 --> 00:22:14,000 story 531 00:22:19,669 --> 00:22:16,640 and he took it uh not to the project 532 00:22:21,430 --> 00:22:19,679 manager but to his division manager who 533 00:22:22,470 --> 00:22:21,440 uh thought about it and said that's 534 00:22:24,470 --> 00:22:22,480 interesting 535 00:22:27,190 --> 00:22:24,480 but it was quite a while before 536 00:22:29,110 --> 00:22:27,200 everybody became convinced that that was 537 00:22:30,870 --> 00:22:29,120 the actual cause of the failure when a 538 00:22:32,710 --> 00:22:30,880 plasma cloud 539 00:22:33,750 --> 00:22:32,720 went up the sides of the atlas and back 540 00:22:35,750 --> 00:22:33,760 down 541 00:22:37,830 --> 00:22:35,760 for just less than a second 542 00:22:45,270 --> 00:22:37,840 it was enough to turn on the tvs and 543 00:22:49,110 --> 00:22:46,710 thank you 544 00:22:50,950 --> 00:22:49,120 i put a couple of my references in here 545 00:22:52,950 --> 00:22:50,960 i i sort of 546 00:22:58,950 --> 00:22:52,960 stretched the point a little bit thank 547 00:23:04,070 --> 00:23:02,230 so go ahead and take five minutes 548 00:23:08,870 --> 00:23:04,080 okay 549 00:23:12,710 --> 00:23:08,880 one question why did you 550 00:23:15,870 --> 00:23:12,720 why did you put this in about the uh 551 00:23:19,270 --> 00:23:15,880 the uh yes reference four decla 552 00:23:21,830 --> 00:23:19,280 1966 declassified 94. 553 00:23:22,630 --> 00:23:21,840 the beautiful book 554 00:23:25,510 --> 00:23:22,640 by 555 00:23:28,470 --> 00:23:25,520 wes huntress and mikhail maroff 556 00:23:31,110 --> 00:23:28,480 tells the real story about 557 00:23:33,750 --> 00:23:31,120 all of the soviet missions 558 00:23:36,310 --> 00:23:33,760 what this reference is is 559 00:23:37,669 --> 00:23:36,320 my story about what we thought they were 560 00:23:38,789 --> 00:23:37,679 doing 561 00:23:41,590 --> 00:23:38,799 published 562 00:23:43,510 --> 00:23:41,600 in the studies in intelligence and 563 00:23:52,630 --> 00:23:43,520 wasn't declassified for a number of 564 00:23:57,909 --> 00:23:53,510 during 565 00:23:59,350 --> 00:23:57,919 your days under jpl i was at abma 566 00:24:00,950 --> 00:23:59,360 i was at the army ballistic missile 567 00:24:03,110 --> 00:24:00,960 agency back in those 568 00:24:05,909 --> 00:24:03,120 in those 50s years and you guys were 569 00:24:08,870 --> 00:24:05,919 transferred in october 58 570 00:24:10,390 --> 00:24:08,880 we held out with the army until july 571 00:24:11,510 --> 00:24:10,400 1960. 572 00:24:15,269 --> 00:24:11,520 the 573 00:24:16,870 --> 00:24:15,279 team it was finally eisenhower who 574 00:24:19,350 --> 00:24:16,880 personally intervened 575 00:24:22,390 --> 00:24:19,360 and so we transferred officially 576 00:24:25,990 --> 00:24:22,400 on the first of july 1960. 577 00:24:28,149 --> 00:24:26,000 also we developed the the jupiter irbm 578 00:24:30,070 --> 00:24:28,159 but then you got the air force we were 579 00:24:32,230 --> 00:24:30,080 told that the army was not going to 580 00:24:34,870 --> 00:24:32,240 deploy that missile that was going to be 581 00:24:37,269 --> 00:24:34,880 deployed by the air force so we had to 582 00:24:39,830 --> 00:24:37,279 paint out u.s army put u.s air force in 583 00:24:42,149 --> 00:24:39,840 there redstone arsenal filled with air 584 00:24:44,070 --> 00:24:42,159 force personnel learning how to operate 585 00:24:47,110 --> 00:24:44,080 the the jupiter 586 00:24:49,909 --> 00:24:47,120 irbm which was deployed in turkey but 587 00:24:52,070 --> 00:24:49,919 the but that jupiter put in your upper 588 00:24:53,830 --> 00:24:52,080 stages you remember the juno too oh yes 589 00:24:57,190 --> 00:24:53,840 of course you didn't talk about that 590 00:24:59,029 --> 00:24:57,200 could you say a few words about juno too 591 00:25:01,029 --> 00:24:59,039 i said the launch vehicle picture was a 592 00:25:03,190 --> 00:25:01,039 little bit confused that was a strong 593 00:25:04,950 --> 00:25:03,200 understatement and you've just 594 00:25:07,269 --> 00:25:04,960 heard a little more about some of the 595 00:25:10,549 --> 00:25:07,279 various pieces of spaghetti that were 596 00:25:14,789 --> 00:25:10,559 all squirming around there go ahead 597 00:25:17,590 --> 00:25:14,799 jim can you just talk a little bit about 598 00:25:19,350 --> 00:25:17,600 how everybody how you and and everybody 599 00:25:20,390 --> 00:25:19,360 realized 600 00:25:23,909 --> 00:25:20,400 the 601 00:25:26,230 --> 00:25:23,919 issues 602 00:25:28,390 --> 00:25:26,240 what what did you expect going in did 603 00:25:30,070 --> 00:25:28,400 you think you could just get away with 604 00:25:32,310 --> 00:25:30,080 you know seeing if it worked and if it 605 00:25:34,549 --> 00:25:32,320 didn't work you'd you'd fix it but then 606 00:25:36,630 --> 00:25:34,559 was there a moment when you all realized 607 00:25:38,789 --> 00:25:36,640 that you were in a much much much more 608 00:25:40,710 --> 00:25:38,799 unforgiving game 609 00:25:43,269 --> 00:25:40,720 i think the answer to the best less 610 00:25:44,710 --> 00:25:43,279 simple quick answer short answer to that 611 00:25:47,430 --> 00:25:44,720 question is 612 00:25:49,830 --> 00:25:47,440 yes reliability was dominant in our 613 00:25:51,190 --> 00:25:49,840 minds and we tried to test everything 614 00:25:52,870 --> 00:25:51,200 you can test 615 00:25:54,710 --> 00:25:52,880 and you get to a point where you've 616 00:25:57,430 --> 00:25:54,720 tested something so many times that 617 00:25:58,870 --> 00:25:57,440 you've worn it out and it's better to 618 00:25:59,909 --> 00:25:58,880 leave it alone 619 00:26:01,430 --> 00:25:59,919 but 620 00:26:03,110 --> 00:26:01,440 as i said 621 00:26:06,149 --> 00:26:03,120 these failures 622 00:26:07,909 --> 00:26:06,159 happened with extremely subtle causes 623 00:26:09,430 --> 00:26:07,919 none of which would have been revealed 624 00:26:12,710 --> 00:26:09,440 in a ground test 625 00:26:15,990 --> 00:26:12,720 for example on ranger 2 626 00:26:18,990 --> 00:26:16,000 gyros in the agina were not turning when 627 00:26:21,669 --> 00:26:19,000 it took off why because the block house 628 00:26:23,909 --> 00:26:21,679 instrumentation was designed in such a 629 00:26:25,750 --> 00:26:23,919 way no matter how much you test it you 630 00:26:26,789 --> 00:26:25,760 can't tell whether the gyros are turning 631 00:26:27,669 --> 00:26:26,799 or not 632 00:26:28,549 --> 00:26:27,679 okay 633 00:26:30,789 --> 00:26:28,559 well 634 00:26:33,750 --> 00:26:30,799 that was corrected 635 00:26:35,830 --> 00:26:33,760 but we'd already lost one mission so 636 00:26:40,310 --> 00:26:35,840 fine the next agena the gyros were 637 00:26:41,430 --> 00:26:40,320 indeed turning but we didn't have 50 638 00:26:44,149 --> 00:26:41,440 missions 639 00:26:49,909 --> 00:26:44,159 the way you do in the army 640 00:26:53,990 --> 00:26:51,510 jim 641 00:26:56,789 --> 00:26:54,000 in one of your slide and concluding one 642 00:27:00,789 --> 00:26:56,799 i guess uh it was said that the 643 00:27:02,070 --> 00:27:00,799 politicians invention of policy do not 644 00:27:04,789 --> 00:27:02,080 help but 645 00:27:08,070 --> 00:27:04,799 probably worsened the situation you know 646 00:27:11,190 --> 00:27:08,080 i completely agree with you because i 647 00:27:12,789 --> 00:27:11,200 just experienced it in my own career you 648 00:27:15,830 --> 00:27:12,799 know but 649 00:27:20,070 --> 00:27:15,840 was it just the case in the ranger 650 00:27:22,789 --> 00:27:20,080 program when the policy tried to assist 651 00:27:29,110 --> 00:27:22,799 you somehow you know but actually 652 00:27:29,120 --> 00:27:33,590 oh all the politicians 653 00:27:38,149 --> 00:27:36,230 the politic politicians were faced with 654 00:27:39,669 --> 00:27:38,159 a problem that's very difficult for a 655 00:27:42,389 --> 00:27:39,679 politician 656 00:27:45,190 --> 00:27:42,399 uh to us it looked as if they were 657 00:27:47,510 --> 00:27:45,200 wasting their time and hours 658 00:27:50,710 --> 00:27:47,520 but in their world 659 00:27:52,230 --> 00:27:50,720 they really did have to consider 660 00:27:55,590 --> 00:27:52,240 whether we were 661 00:27:57,430 --> 00:27:55,600 we happy engineers who were just going 662 00:27:59,590 --> 00:27:57,440 along always thinking we could make the 663 00:28:01,990 --> 00:27:59,600 next one work and eventually we did make 664 00:28:04,470 --> 00:28:02,000 the next three of them work fine 665 00:28:06,789 --> 00:28:04,480 everybody ended up a hero so from an 666 00:28:08,630 --> 00:28:06,799 engineering standpoint we did exactly 667 00:28:10,230 --> 00:28:08,640 the same thing we'd always previously 668 00:28:12,549 --> 00:28:10,240 done in the army 669 00:28:14,149 --> 00:28:12,559 you find a failure you fix it launch the 670 00:28:15,430 --> 00:28:14,159 next thing it has a different failure 671 00:28:17,110 --> 00:28:15,440 you fix that 672 00:28:18,149 --> 00:28:17,120 eventually you get to where you want to 673 00:28:20,789 --> 00:28:18,159 be 674 00:28:25,510 --> 00:28:20,799 okay but ranger 675 00:28:28,789 --> 00:28:25,520 was operating in a different environment 676 00:28:31,029 --> 00:28:28,799 and the answer to mikhail's question is 677 00:28:33,990 --> 00:28:31,039 politicians 678 00:28:36,549 --> 00:28:34,000 could have done us tremendous damage 679 00:28:38,710 --> 00:28:36,559 because one question that was arose and 680 00:28:39,590 --> 00:28:38,720 it was treated in the aeronautical press 681 00:28:42,149 --> 00:28:39,600 then 682 00:28:44,310 --> 00:28:42,159 is what's a university laboratory doing 683 00:28:46,070 --> 00:28:44,320 in this business anyway with a 60 684 00:28:49,029 --> 00:28:46,080 million dollar mission 685 00:28:49,990 --> 00:28:49,039 500 people working on a big deal 686 00:28:52,149 --> 00:28:50,000 you know 687 00:28:54,070 --> 00:28:52,159 so that question 688 00:28:55,830 --> 00:28:54,080 had it gone the other way 689 00:28:58,149 --> 00:28:55,840 had nasa not 690 00:29:00,470 --> 00:28:58,159 told the politicians to hey get off our 691 00:29:02,950 --> 00:29:00,480 backs we the jpl knows what it's doing 692 00:29:04,149 --> 00:29:02,960 leave us alone 693 00:29:10,070 --> 00:29:04,159 thank you very much we're gonna have 694 00:29:14,149 --> 00:29:12,230 our next presenter is john sarkisian who 695 00:29:35,909 --> 00:29:14,159 is going to talk about mariner 2 and the 696 00:29:35,919 --> 00:29:41,190 nope 697 00:29:41,200 --> 00:29:50,549 wrong john 698 00:29:50,559 --> 00:29:54,789 oh which one was that 699 00:29:59,269 --> 00:29:56,710 okay 700 00:30:01,510 --> 00:29:59,279 well firstly um i'd first like to thank 701 00:30:03,669 --> 00:30:01,520 um bill barry and the organizers for 702 00:30:05,430 --> 00:30:03,679 inviting me along here to to address you 703 00:30:10,310 --> 00:30:05,440 this afternoon and it really is a great 704 00:30:15,029 --> 00:30:13,669 the csiro parks radio telescope is one 705 00:30:16,310 --> 00:30:15,039 of the world's great research 706 00:30:18,549 --> 00:30:16,320 instruments 707 00:30:20,710 --> 00:30:18,559 it is arguably the finest single dish 708 00:30:23,269 --> 00:30:20,720 radio telescope in the world 709 00:30:24,710 --> 00:30:23,279 back in 2006 a study published in the 710 00:30:26,549 --> 00:30:24,720 journal nature 711 00:30:29,430 --> 00:30:26,559 ranked it second only to the vla in 712 00:30:31,830 --> 00:30:29,440 terms of its scientific impact 713 00:30:34,070 --> 00:30:31,840 it is owned and operated by the 714 00:30:35,990 --> 00:30:34,080 commonwealth scientific and 715 00:30:37,750 --> 00:30:36,000 industrial research organization or 716 00:30:39,029 --> 00:30:37,760 csiro 717 00:30:41,669 --> 00:30:39,039 of australia 718 00:30:44,310 --> 00:30:41,679 and when it was built in 1961 it was the 719 00:30:46,149 --> 00:30:44,320 most advanced radio telescope 720 00:30:48,630 --> 00:30:46,159 in the world 721 00:30:50,870 --> 00:30:48,640 it was also recognized very early on 722 00:30:53,190 --> 00:30:50,880 that its design made it a near ideal 723 00:30:54,870 --> 00:30:53,200 instrument for tracking spacecraft in 724 00:30:58,230 --> 00:30:54,880 deep space 725 00:31:00,149 --> 00:30:58,240 this attracted the attention of nasa jpl 726 00:31:02,389 --> 00:31:00,159 where it had its most profound impact in 727 00:31:05,269 --> 00:31:02,399 the design of the large aperture 728 00:31:08,310 --> 00:31:05,279 antennas of the the the deep space 729 00:31:13,509 --> 00:31:10,630 as you can see from this table 730 00:31:15,590 --> 00:31:13,519 um the space missions that the the parks 731 00:31:18,630 --> 00:31:15,600 telescope has been involved in 732 00:31:20,870 --> 00:31:18,640 um spans the the five decades of the 733 00:31:22,710 --> 00:31:20,880 salt system exploration from mariner 2 734 00:31:24,789 --> 00:31:22,720 at the very beginning all the way 735 00:31:27,269 --> 00:31:24,799 through to the latest mission curiosity 736 00:31:29,590 --> 00:31:27,279 just a few months ago 737 00:31:32,230 --> 00:31:29,600 the highlight was undoubtedly the apollo 738 00:31:34,470 --> 00:31:32,240 missions from especially apollos 11 739 00:31:36,230 --> 00:31:34,480 through to 17. 740 00:31:39,430 --> 00:31:36,240 we also played a critical role in the 741 00:31:41,029 --> 00:31:39,440 galileo mission to jupiter and also in 742 00:31:43,509 --> 00:31:41,039 the huygens 743 00:31:45,110 --> 00:31:43,519 landing on titan where we actually were 744 00:31:51,269 --> 00:31:45,120 able to salvage the doppler wind 745 00:31:55,190 --> 00:31:54,070 but how did it all begin 746 00:31:57,269 --> 00:31:55,200 well 747 00:31:59,430 --> 00:31:57,279 it was conceived by edward taffy bowen 748 00:32:01,430 --> 00:31:59,440 in 1954 749 00:32:03,350 --> 00:32:01,440 taffy was the visionary and dynamic 750 00:32:07,669 --> 00:32:03,360 chief of the csiro's radio physics 751 00:32:09,909 --> 00:32:07,679 division for 25 years from 1946 to 1971. 752 00:32:11,830 --> 00:32:09,919 under his leadership the radio physics 753 00:32:13,669 --> 00:32:11,840 division developed as a pioneer and 754 00:32:15,750 --> 00:32:13,679 world leader in the emerging science of 755 00:32:17,990 --> 00:32:15,760 radio astronomy in the immediate 756 00:32:20,549 --> 00:32:18,000 post-war years 757 00:32:22,389 --> 00:32:20,559 but by the early 1950s 758 00:32:24,070 --> 00:32:22,399 taffy was thinking of the next stage of 759 00:32:26,149 --> 00:32:24,080 development of radio astronomy in 760 00:32:28,789 --> 00:32:26,159 australia and he determined that the 761 00:32:31,750 --> 00:32:28,799 best all-round instrument for continuing 762 00:32:33,509 --> 00:32:31,760 the csiro's pioneering efforts in radio 763 00:32:37,269 --> 00:32:33,519 astronomy 764 00:32:39,029 --> 00:32:37,279 was a large fully steerable dish antenna 765 00:32:41,110 --> 00:32:39,039 at the time such an instrument was 766 00:32:43,029 --> 00:32:41,120 beyond the budget of the csiro so he 767 00:32:45,190 --> 00:32:43,039 called on his old boy network so to 768 00:32:47,269 --> 00:32:45,200 speak of contacts that he built up 769 00:32:51,590 --> 00:32:47,279 during the war 770 00:32:55,509 --> 00:32:53,110 firstly 771 00:32:56,710 --> 00:32:55,519 he approached the carnegie corporation 772 00:32:59,269 --> 00:32:56,720 at the time 773 00:33:01,750 --> 00:32:59,279 it was the president of the carnegie 774 00:33:03,190 --> 00:33:01,760 institute in washington was headed by uh 775 00:33:04,149 --> 00:33:03,200 well the president of it was vanneva 776 00:33:04,950 --> 00:33:04,159 bush 777 00:33:06,389 --> 00:33:04,960 who 778 00:33:08,389 --> 00:33:06,399 during the war was 779 00:33:10,310 --> 00:33:08,399 president roosevelt's um science advisor 780 00:33:12,950 --> 00:33:10,320 the man who initiated the the manhattan 781 00:33:15,350 --> 00:33:12,960 project and he was also the the founder 782 00:33:17,830 --> 00:33:15,360 of the national science foundation 783 00:33:19,669 --> 00:33:17,840 and from his very close personal 784 00:33:21,830 --> 00:33:19,679 relationships um professional 785 00:33:23,909 --> 00:33:21,840 relationship with um 786 00:33:25,350 --> 00:33:23,919 vaneva bush he acquired a quarter of a 787 00:33:27,029 --> 00:33:25,360 million dollars to get the project 788 00:33:28,789 --> 00:33:27,039 started 789 00:33:30,630 --> 00:33:28,799 he then followed up with 790 00:33:32,789 --> 00:33:30,640 a similar 791 00:33:34,789 --> 00:33:32,799 amount from the rockefeller foundation 792 00:33:37,029 --> 00:33:34,799 the the president of of the rockefeller 793 00:33:39,509 --> 00:33:37,039 foundation was dean rusk the future 794 00:33:41,669 --> 00:33:39,519 secretary of state of um in the kennedy 795 00:33:44,710 --> 00:33:41,679 and johnson administrations again he 796 00:33:46,310 --> 00:33:44,720 knew taffy during the the war period 797 00:33:48,549 --> 00:33:46,320 and 798 00:33:50,470 --> 00:33:48,559 richard casey who is the the man who 799 00:33:52,870 --> 00:33:50,480 actually set up the radio physics 800 00:33:54,630 --> 00:33:52,880 laboratory within the csiro as a secret 801 00:33:56,870 --> 00:33:54,640 wartime laboratory 802 00:33:59,269 --> 00:33:56,880 was a minister in the then australian 803 00:34:01,990 --> 00:33:59,279 government and responsible for the csiro 804 00:34:04,549 --> 00:34:02,000 and he managed to convince and he was a 805 00:34:06,630 --> 00:34:04,559 great supporter of the of taffy and the 806 00:34:08,310 --> 00:34:06,640 telescope project and he managed to 807 00:34:09,990 --> 00:34:08,320 convince the australian 808 00:34:11,990 --> 00:34:10,000 prime minister to support it with 809 00:34:14,230 --> 00:34:12,000 matching funds and then combined with 810 00:34:15,669 --> 00:34:14,240 additional private donations and with 811 00:34:17,349 --> 00:34:15,679 the additional 812 00:34:19,510 --> 00:34:17,359 funds from the australian government and 813 00:34:21,430 --> 00:34:19,520 the rockefeller to make up a shortfall 814 00:34:24,149 --> 00:34:21,440 towards the end of the project he was 815 00:34:26,149 --> 00:34:24,159 able to acquire just over 1.4 million 816 00:34:28,230 --> 00:34:26,159 dollars to build the telescope which 817 00:34:32,790 --> 00:34:28,240 even in those days was considered 818 00:34:35,990 --> 00:34:34,710 the telescope itself 819 00:34:38,470 --> 00:34:36,000 um 820 00:34:40,389 --> 00:34:38,480 was designed by the freeman fox and 821 00:34:42,069 --> 00:34:40,399 partners a british firm they were 822 00:34:44,629 --> 00:34:42,079 actually famous especially in australia 823 00:34:46,069 --> 00:34:44,639 as being the the designers of the sydney 824 00:34:47,669 --> 00:34:46,079 harbour bridge 825 00:34:49,109 --> 00:34:47,679 and 826 00:34:52,310 --> 00:34:49,119 they were contracted to design the 827 00:34:53,109 --> 00:34:52,320 telescope to csiro specifications 828 00:34:55,109 --> 00:34:53,119 and 829 00:34:57,270 --> 00:34:55,119 the csro engineer harry minnett 830 00:35:04,069 --> 00:34:57,280 supervised the design of the telescope 831 00:35:07,829 --> 00:35:06,310 this was much longer than they expected 832 00:35:11,030 --> 00:35:07,839 but it paid off in the end because it 833 00:35:13,510 --> 00:35:11,040 meant that they got the design right 834 00:35:14,550 --> 00:35:13,520 the telescope um actually incorporated 835 00:35:17,270 --> 00:35:14,560 several 836 00:35:20,390 --> 00:35:17,280 um very innovative design features i'll 837 00:35:23,589 --> 00:35:20,400 just come to them firstly it was 838 00:35:26,069 --> 00:35:23,599 pivoted in the center it's like an 839 00:35:27,670 --> 00:35:26,079 inverted umbrella 840 00:35:30,150 --> 00:35:27,680 as you can see 841 00:35:31,990 --> 00:35:30,160 it used it was it had an azimuth mount 842 00:35:33,430 --> 00:35:32,000 which is unusual for its time for a 843 00:35:35,829 --> 00:35:33,440 structure that large 844 00:35:37,910 --> 00:35:35,839 also um in order for it to track objects 845 00:35:39,190 --> 00:35:37,920 smoothly across the sky it incorporated 846 00:35:41,030 --> 00:35:39,200 a new 847 00:35:42,630 --> 00:35:41,040 invention of the master equatorial 848 00:35:44,550 --> 00:35:42,640 system 849 00:35:46,550 --> 00:35:44,560 and it was a basically just a small 850 00:35:48,550 --> 00:35:46,560 equatorially mounted optical telescope 851 00:35:50,310 --> 00:35:48,560 located at the intersection of the 852 00:35:53,670 --> 00:35:50,320 altitude and azimuth axis of the 853 00:35:57,910 --> 00:35:55,829 um and um 854 00:35:59,589 --> 00:35:57,920 essentially the dish was slaved to that 855 00:36:02,069 --> 00:35:59,599 equatorially op mounted optical 856 00:36:04,630 --> 00:36:02,079 telescope via a servo drive system that 857 00:36:07,510 --> 00:36:04,640 enabled it to very smoothly track 858 00:36:08,390 --> 00:36:07,520 objects across the sky and finally 859 00:36:10,630 --> 00:36:08,400 it had 860 00:36:13,430 --> 00:36:10,640 spiral purlins on the dish to to give it 861 00:36:15,349 --> 00:36:13,440 strength 862 00:36:16,950 --> 00:36:15,359 the site chosen for the telescope was 863 00:36:20,230 --> 00:36:16,960 near the town of parks 864 00:36:21,990 --> 00:36:20,240 about 350 kilometers west of sydney in 865 00:36:24,230 --> 00:36:22,000 the central west of new south wales in 866 00:36:25,670 --> 00:36:24,240 australia and the reason it was chosen 867 00:36:27,829 --> 00:36:25,680 was because of those mountains in the 868 00:36:29,349 --> 00:36:27,839 background of the photograph there 869 00:36:31,030 --> 00:36:29,359 they protected us from the radio 870 00:36:32,710 --> 00:36:31,040 emissions from the larger population 871 00:36:35,030 --> 00:36:32,720 centers further east 872 00:36:38,069 --> 00:36:35,040 such as sydney for example i mean so the 873 00:36:39,990 --> 00:36:38,079 area was a very radio quiet site which 874 00:36:41,829 --> 00:36:40,000 was essential for a large sensitive 875 00:36:43,109 --> 00:36:41,839 instrument like parks 876 00:36:45,349 --> 00:36:43,119 that young 877 00:36:47,109 --> 00:36:45,359 fellow there um standing next to the 878 00:36:48,069 --> 00:36:47,119 stake where the actual telescope was 879 00:36:49,750 --> 00:36:48,079 built 880 00:36:53,990 --> 00:36:49,760 he's now 59 years old and he's a good 881 00:36:56,710 --> 00:36:54,000 friend of mine is the local farmer still 882 00:36:59,589 --> 00:36:56,720 um the main constructor for the the 883 00:37:01,990 --> 00:36:59,599 telescope was man of west germany 884 00:37:04,550 --> 00:37:02,000 um and so already you can see that it's 885 00:37:07,030 --> 00:37:04,560 it's beginning to take on the after 886 00:37:09,430 --> 00:37:07,040 of an international project with 887 00:37:11,349 --> 00:37:09,440 the united states australia um the 888 00:37:12,950 --> 00:37:11,359 british and the germans all involved in 889 00:37:18,870 --> 00:37:12,960 the construction 890 00:37:21,349 --> 00:37:18,880 1959 and over the next 21 months 891 00:37:23,829 --> 00:37:21,359 when the germans arrived to to build the 892 00:37:25,990 --> 00:37:23,839 the turret they're able to to weld the 893 00:37:27,750 --> 00:37:26,000 the ribs into into shape and then they 894 00:37:30,230 --> 00:37:27,760 lifted them one at a time bolted them 895 00:37:31,990 --> 00:37:30,240 onto the the turret and then when that 896 00:37:35,670 --> 00:37:32,000 was done they then put the focus cabin 897 00:37:38,069 --> 00:37:35,680 up on the the the apex and then paneled 898 00:37:40,230 --> 00:37:38,079 the the dish and it said it was all done 899 00:37:42,470 --> 00:37:40,240 in the amazingly short period of just 21 900 00:37:44,150 --> 00:37:42,480 months and that was a and there was very 901 00:37:45,829 --> 00:37:44,160 little problems encountered in the 902 00:37:48,870 --> 00:37:45,839 construction and it was mainly due to 903 00:37:50,950 --> 00:37:48,880 the the time spent in designing it 904 00:37:52,630 --> 00:37:50,960 initially 905 00:37:54,630 --> 00:37:52,640 the first tip of the telescope occurred 906 00:37:56,870 --> 00:37:54,640 in october 1961 907 00:37:58,390 --> 00:37:56,880 and then a mid-october 61 and then two 908 00:38:00,630 --> 00:37:58,400 weeks later it was officially opened by 909 00:38:03,589 --> 00:38:00,640 the governor general of australia 910 00:38:07,109 --> 00:38:05,510 the first director of the observatory 911 00:38:10,150 --> 00:38:07,119 was john bolton 912 00:38:11,910 --> 00:38:10,160 he was a legendary figure um 913 00:38:15,589 --> 00:38:11,920 a pioneer of radio astronomy in 914 00:38:17,349 --> 00:38:15,599 australia and he also in 1955 915 00:38:19,670 --> 00:38:17,359 moved to caltech and and started the 916 00:38:21,750 --> 00:38:19,680 radio astronomy program there 917 00:38:24,390 --> 00:38:21,760 and founded the owens valley observatory 918 00:38:26,550 --> 00:38:24,400 which is um 919 00:38:30,870 --> 00:38:26,560 which we had very close um contacts with 920 00:38:34,230 --> 00:38:32,470 but how do we get involved in the space 921 00:38:36,230 --> 00:38:34,240 missions 922 00:38:37,030 --> 00:38:36,240 well the story goes back to the period 923 00:38:39,430 --> 00:38:37,040 um 924 00:38:40,390 --> 00:38:39,440 the interest that that jpl had in in 925 00:38:43,030 --> 00:38:40,400 parks 926 00:38:45,750 --> 00:38:43,040 um went to before even that when the 927 00:38:48,630 --> 00:38:45,760 telescope was was built began on the 6th 928 00:38:52,390 --> 00:38:48,640 of march 1959 when the us army's pioneer 929 00:38:55,190 --> 00:38:52,400 4 spacecraft flew by the moon um at what 930 00:38:57,750 --> 00:38:55,200 was then a record distance of 650 000 931 00:38:59,910 --> 00:38:57,760 kilometers and unfortunately 932 00:39:01,109 --> 00:38:59,920 nasa jpl could not communicate with it 933 00:39:02,150 --> 00:39:01,119 effectively 934 00:39:04,950 --> 00:39:02,160 even though it was a perfectly 935 00:39:07,190 --> 00:39:04,960 functioning spacecraft because its small 936 00:39:09,190 --> 00:39:07,200 26 meter antenna at goldstone just 937 00:39:12,630 --> 00:39:09,200 didn't have the sensitivity to 938 00:39:13,670 --> 00:39:12,640 to communicate with it effectively 939 00:39:16,310 --> 00:39:13,680 and so 940 00:39:18,390 --> 00:39:16,320 jpl realized that what it needed was the 941 00:39:21,190 --> 00:39:18,400 it was a much larger and more sensitive 942 00:39:22,870 --> 00:39:21,200 antenna than this 26 meter antennas that 943 00:39:25,510 --> 00:39:22,880 it was planning for its deep space 944 00:39:28,069 --> 00:39:25,520 network or the fledgling deep space 945 00:39:30,230 --> 00:39:28,079 and so the requirements for such a an 946 00:39:32,310 --> 00:39:30,240 antenna were that it 947 00:39:34,550 --> 00:39:32,320 needed to be six to 12 db improvement 948 00:39:36,630 --> 00:39:34,560 over the existing 26 meter array they 949 00:39:38,069 --> 00:39:36,640 were planning 950 00:39:41,829 --> 00:39:38,079 which meant it had to be somewhere in 951 00:39:43,750 --> 00:39:41,839 the order of 60 to 80 meters in diameter 952 00:39:46,710 --> 00:39:43,760 it had to have optimum performance at 953 00:39:49,589 --> 00:39:46,720 2.2 gigahertz at s-band in other words 954 00:39:51,109 --> 00:39:49,599 the surface had to be extremely accurate 955 00:39:54,550 --> 00:39:51,119 um you needed to have a pointing 956 00:39:55,750 --> 00:39:54,560 accuracy of about 1.2 minutes of arc 957 00:39:57,430 --> 00:39:55,760 and 958 00:39:59,270 --> 00:39:57,440 finally needed to have a slew rate of 959 00:40:01,510 --> 00:39:59,280 around 10 degrees a minute 960 00:40:03,750 --> 00:40:01,520 and it was no surprise at all that these 961 00:40:07,589 --> 00:40:03,760 requirements match the the proposed park 962 00:40:09,510 --> 00:40:07,599 telescope very very closely 963 00:40:11,910 --> 00:40:09,520 consequently during the the tender and 964 00:40:14,309 --> 00:40:11,920 construction phase of the telescope 965 00:40:17,430 --> 00:40:14,319 jpl made several representations to the 966 00:40:19,270 --> 00:40:17,440 csiro with the view of of formally 967 00:40:20,630 --> 00:40:19,280 incorporating it into the deep space 968 00:40:22,309 --> 00:40:20,640 network 969 00:40:24,550 --> 00:40:22,319 finally however a cooperative space 970 00:40:25,910 --> 00:40:24,560 exploration program was proposed 971 00:40:28,150 --> 00:40:25,920 and you can see that it was for the 972 00:40:30,390 --> 00:40:28,160 occasional use of parks for data 973 00:40:32,470 --> 00:40:30,400 requisition of a short-term nature where 974 00:40:33,750 --> 00:40:32,480 an extremely strong and reliable signal 975 00:40:35,670 --> 00:40:33,760 was required 976 00:40:37,829 --> 00:40:35,680 and in fact to this day 977 00:40:39,829 --> 00:40:37,839 it is still the basis in rationale for 978 00:40:42,870 --> 00:40:39,839 parks's inclusion in space tracking 979 00:40:48,309 --> 00:40:45,910 in 1962 a nasa research grant was 980 00:40:50,630 --> 00:40:48,319 awarded to the csiro to study the dish 981 00:40:52,309 --> 00:40:50,640 characteristics with a view to it 982 00:40:55,829 --> 00:40:52,319 contributing toward the design of the 983 00:40:58,069 --> 00:40:55,839 proposed jpl large aperture antennas 984 00:41:00,630 --> 00:40:58,079 william pickering the jpl director 985 00:41:02,470 --> 00:41:00,640 invited the csro to to participate in 986 00:41:05,349 --> 00:41:02,480 the feasibility studies and 987 00:41:09,109 --> 00:41:05,359 specification reviews of the the jpl 988 00:41:13,109 --> 00:41:11,270 um the giant the grant also called for a 989 00:41:15,270 --> 00:41:13,119 detailed study to determine the 990 00:41:17,589 --> 00:41:15,280 performance parameters of the parks 991 00:41:18,950 --> 00:41:17,599 telescope in regards to to those 992 00:41:21,030 --> 00:41:18,960 premises you see there the structural 993 00:41:23,270 --> 00:41:21,040 behavior characteristics of the drive 994 00:41:25,349 --> 00:41:23,280 system radio frequency performance 995 00:41:26,870 --> 00:41:25,359 vibration characteristics but also 996 00:41:29,990 --> 00:41:26,880 measurements of the disc shape in the 997 00:41:32,550 --> 00:41:30,000 zenith and tilted positions 998 00:41:34,470 --> 00:41:32,560 as a result of these studies 999 00:41:37,190 --> 00:41:34,480 over the next few over the the next few 1000 00:41:38,550 --> 00:41:37,200 years um more than 30 research papers 1001 00:41:40,870 --> 00:41:38,560 were published on the design and 1002 00:41:42,390 --> 00:41:40,880 performance of the telescope parks was 1003 00:41:44,470 --> 00:41:42,400 not only the most advanced radio 1004 00:41:48,309 --> 00:41:44,480 telescope in the world it also became 1005 00:41:49,670 --> 00:41:48,319 the most extensively studied 1006 00:41:51,349 --> 00:41:49,680 and the reason was because this 1007 00:41:53,030 --> 00:41:51,359 information was considered to be of 1008 00:41:58,230 --> 00:41:53,040 critical importance in the design and 1009 00:42:02,550 --> 00:42:00,630 the caltech and jpl luminaries involved 1010 00:42:05,589 --> 00:42:02,560 in that design were people such as bruce 1011 00:42:07,670 --> 00:42:05,599 rule bill merrick ebrechten and sononai 1012 00:42:10,150 --> 00:42:07,680 liaise very closely with the csro 1013 00:42:14,470 --> 00:42:10,160 engineers harry minet and and others to 1014 00:42:16,950 --> 00:42:14,480 to ensure that the the dsn antennas were 1015 00:42:18,550 --> 00:42:16,960 operated as and as well as as they'd 1016 00:42:19,990 --> 00:42:18,560 hope 1017 00:42:22,550 --> 00:42:20,000 now another aspect of the park's 1018 00:42:25,510 --> 00:42:22,560 telescope impact on space tracking was 1019 00:42:27,030 --> 00:42:25,520 in the location of the dsn stations 1020 00:42:28,710 --> 00:42:27,040 as you can see the very first station 1021 00:42:31,670 --> 00:42:28,720 was located at goldstone because only 1022 00:42:33,190 --> 00:42:31,680 just a few hours drive from from jpl but 1023 00:42:34,950 --> 00:42:33,200 that then dictated where the other two 1024 00:42:36,870 --> 00:42:34,960 stations would go they needed to have 1025 00:42:39,910 --> 00:42:36,880 their stations roughly equidistant 1026 00:42:42,390 --> 00:42:39,920 around the globe um 120 degrees apart 1027 00:42:44,870 --> 00:42:42,400 roughly and so in the early 19 early 1028 00:42:46,950 --> 00:42:44,880 late 50s early 60s the other two 1029 00:42:49,750 --> 00:42:46,960 stations were located at johannesburg in 1030 00:42:51,670 --> 00:42:49,760 western um in south africa and also at 1031 00:42:53,990 --> 00:42:51,680 ireland lagoon at the women rocket range 1032 00:42:55,990 --> 00:42:54,000 in south australia but for various 1033 00:42:58,309 --> 00:42:56,000 reasons which i won't go into just lack 1034 00:43:01,190 --> 00:42:58,319 of time there they had to to shift the 1035 00:43:03,670 --> 00:43:01,200 locations of those other stations and um 1036 00:43:06,470 --> 00:43:03,680 one went to to madrid and the other went 1037 00:43:08,950 --> 00:43:06,480 to the tidman villa nature reserve very 1038 00:43:11,430 --> 00:43:08,960 close to canberra the australian capital 1039 00:43:13,510 --> 00:43:11,440 um and the reason tidbinbilla was chosen 1040 00:43:15,589 --> 00:43:13,520 was because taffy bone was the chairman 1041 00:43:17,750 --> 00:43:15,599 of the site selection committee and he 1042 00:43:19,750 --> 00:43:17,760 chose that site because 1043 00:43:22,309 --> 00:43:19,760 ted ben biller was on almost exactly the 1044 00:43:24,550 --> 00:43:22,319 same longitude as the parks telescope 1045 00:43:27,109 --> 00:43:24,560 because he argued that being on the same 1046 00:43:29,270 --> 00:43:27,119 longitude the two would see the same sky 1047 00:43:31,109 --> 00:43:29,280 simultaneously and that in the future 1048 00:43:34,710 --> 00:43:31,119 nasa may want to 1049 00:43:38,230 --> 00:43:34,720 link or array the dishes together 1050 00:43:39,910 --> 00:43:38,240 to enhance the capabilities so that 1051 00:43:41,670 --> 00:43:39,920 the two working together would be a much 1052 00:43:43,829 --> 00:43:41,680 more powerful more useful instrument 1053 00:43:46,069 --> 00:43:43,839 than the two working individually and of 1054 00:43:47,829 --> 00:43:46,079 course that was realized some 20 or so 1055 00:43:50,710 --> 00:43:47,839 years later with the voyager 2 1056 00:43:53,109 --> 00:43:50,720 encounters of uranus and neptune and 1057 00:43:58,150 --> 00:43:53,119 also very critically with the galileo 1058 00:44:03,510 --> 00:44:00,950 now it was during the this design and 1059 00:44:04,550 --> 00:44:03,520 study period that that mariner 2 was 1060 00:44:05,510 --> 00:44:04,560 launched 1061 00:44:08,230 --> 00:44:05,520 um 1062 00:44:11,030 --> 00:44:08,240 as you all know it was it flew by venus 1063 00:44:13,510 --> 00:44:11,040 on the 14th of december 1962 and it flew 1064 00:44:16,230 --> 00:44:13,520 within just under 35 000 kilometers of 1065 00:44:18,470 --> 00:44:16,240 the of the surface 1066 00:44:20,470 --> 00:44:18,480 now taffy bone harry minnett decided 1067 00:44:22,150 --> 00:44:20,480 that tracking mariner 2 would be the 1068 00:44:24,630 --> 00:44:22,160 would be an excellent demonstration of 1069 00:44:27,190 --> 00:44:24,640 the parks telescope's capabilities for 1070 00:44:28,950 --> 00:44:27,200 communication at great distances 1071 00:44:30,790 --> 00:44:28,960 and essentially the experiment would be 1072 00:44:32,630 --> 00:44:30,800 a simple one involving the measurement 1073 00:44:35,750 --> 00:44:32,640 of spacecraft position 1074 00:44:37,829 --> 00:44:35,760 signal level and doppler frequency 1075 00:44:40,309 --> 00:44:37,839 it did not include the reception of 1076 00:44:42,309 --> 00:44:40,319 telemetry but was simply intended to 1077 00:44:45,030 --> 00:44:42,319 establish the technique and measure the 1078 00:44:47,670 --> 00:44:45,040 performance of a 64 metre 1079 00:44:52,550 --> 00:44:49,430 parks tracked it for two weeks beginning 1080 00:44:54,309 --> 00:44:52,560 on the 20th of december 1962 until the 1081 00:44:56,390 --> 00:44:54,319 3rd of january 1082 00:44:58,950 --> 00:44:56,400 when the signal was finally 1083 00:45:00,870 --> 00:44:58,960 finally lost 1084 00:45:03,829 --> 00:45:00,880 jpl loaned 1085 00:45:05,829 --> 00:45:03,839 parks a nail band transportable phase 1086 00:45:07,349 --> 00:45:05,839 lock receiver which the astronomers 1087 00:45:08,630 --> 00:45:07,359 dubbed the ancient mariner as you can 1088 00:45:10,150 --> 00:45:08,640 see 1089 00:45:11,990 --> 00:45:10,160 because it looked quite old even then i 1090 00:45:13,910 --> 00:45:12,000 think 1091 00:45:16,069 --> 00:45:13,920 but but the thing that i found most 1092 00:45:18,230 --> 00:45:16,079 amazing was that it had a 20 hertz gate 1093 00:45:19,829 --> 00:45:18,240 that could be manually tuned so the 1094 00:45:22,790 --> 00:45:19,839 astronomers had to know the the 1095 00:45:23,670 --> 00:45:22,800 frequency very very precisely and tune 1096 00:45:27,109 --> 00:45:23,680 the tune 1097 00:45:29,109 --> 00:45:27,119 to with to very close to the um to the 1098 00:45:30,950 --> 00:45:29,119 um frequent doppler shifted frequency in 1099 00:45:32,870 --> 00:45:30,960 the pass span and so they could get it 1100 00:45:35,109 --> 00:45:32,880 in that 20 hertz gate and then lock on 1101 00:45:37,430 --> 00:45:35,119 to the to the signal 1102 00:45:41,910 --> 00:45:39,270 because these tracks were and if we're 1103 00:45:44,630 --> 00:45:41,920 on an informal basis jpl did not provide 1104 00:45:48,069 --> 00:45:44,640 position and frequency predicts so harry 1105 00:45:49,190 --> 00:45:48,079 minette resorted to calculating um these 1106 00:45:51,829 --> 00:45:49,200 himself 1107 00:45:54,230 --> 00:45:51,839 using slide rule and pencil and paper 1108 00:45:56,150 --> 00:45:54,240 but he needed to know both the position 1109 00:45:58,069 --> 00:45:56,160 and the frequency to lock onto the 1110 00:45:59,910 --> 00:45:58,079 signal 1111 00:46:01,270 --> 00:45:59,920 he experienced great trouble at this as 1112 00:46:03,430 --> 00:46:01,280 you could imagine because he was never 1113 00:46:06,230 --> 00:46:03,440 sure whether the position was right and 1114 00:46:07,109 --> 00:46:06,240 the frequency is wrong or vice versa or 1115 00:46:09,030 --> 00:46:07,119 both 1116 00:46:11,670 --> 00:46:09,040 um so eventually after a week of 1117 00:46:13,270 --> 00:46:11,680 fruitless effort he contacted jpl who 1118 00:46:14,390 --> 00:46:13,280 sent him the predicts and he immediately 1119 00:46:16,309 --> 00:46:14,400 was able to 1120 00:46:18,950 --> 00:46:16,319 to to lock on to the 1121 00:46:21,589 --> 00:46:18,960 um to the signal 1122 00:46:23,190 --> 00:46:21,599 um as you see there and here i found um 1123 00:46:25,270 --> 00:46:23,200 in the national archives um he's 1124 00:46:28,150 --> 00:46:25,280 hand-drawn plot of the results and we 1125 00:46:29,750 --> 00:46:28,160 just zoom in a little bit then 1126 00:46:33,430 --> 00:46:29,760 you can see that the park's telescope 1127 00:46:35,910 --> 00:46:33,440 had an overall 5 db um advantage over 1128 00:46:37,430 --> 00:46:35,920 the 26 meter antennas in this case um 1129 00:46:39,109 --> 00:46:37,440 the one at warmer 1130 00:46:42,630 --> 00:46:39,119 and it should have actually had a have 1131 00:46:44,150 --> 00:46:42,640 had an 8 db advantage but because 1132 00:46:45,829 --> 00:46:44,160 a circularly polarized feed was 1133 00:46:47,670 --> 00:46:45,839 unavailable the astronomers had used the 1134 00:46:51,910 --> 00:46:47,680 linearly polarized astronomy feed 1135 00:46:53,670 --> 00:46:51,920 instead that included a 3db penalty 1136 00:46:55,589 --> 00:46:53,680 nonetheless the experiment was 1137 00:46:57,750 --> 00:46:55,599 considered a great success and the 1138 00:46:59,670 --> 00:46:57,760 results were included in the the study 1139 00:47:02,710 --> 00:46:59,680 reports that verified the soundness of 1140 00:47:05,190 --> 00:47:02,720 the the of the design 1141 00:47:07,430 --> 00:47:05,200 and as a result of as a consequence of 1142 00:47:10,069 --> 00:47:07,440 these parks became the model for the jpl 1143 00:47:11,750 --> 00:47:10,079 large aperture antennas 1144 00:47:13,829 --> 00:47:11,760 as you can see they were all pivoted in 1145 00:47:16,150 --> 00:47:13,839 the center just like parks they had an 1146 00:47:17,910 --> 00:47:16,160 alt azimuth mount and they incorporated 1147 00:47:20,549 --> 00:47:17,920 the master equatorial system and they 1148 00:47:21,829 --> 00:47:20,559 were all 64 meters in diameter the 1149 00:47:24,390 --> 00:47:21,839 goldstone dish was eventually 1150 00:47:27,190 --> 00:47:24,400 commissioned in may 1966 1151 00:47:29,589 --> 00:47:27,200 but before then mariner 4 was flying by 1152 00:47:31,910 --> 00:47:29,599 mars and the goldstone dish was still a 1153 00:47:33,990 --> 00:47:31,920 year away from completion so pax was 1154 00:47:36,790 --> 00:47:34,000 approached to provide the 1155 00:47:39,510 --> 00:47:36,800 64 meter capability for the dsn 1156 00:47:41,670 --> 00:47:39,520 22 images were returned of the martian 1157 00:47:44,630 --> 00:47:41,680 surface and parks provided a three db 1158 00:47:46,630 --> 00:47:44,640 improvement of the existing um dsn array 1159 00:47:50,309 --> 00:47:46,640 in fact all antennas combined parks 1160 00:47:52,069 --> 00:47:50,319 provided double the the strength of that 1161 00:47:54,710 --> 00:47:52,079 the data from parks was combined with 1162 00:47:56,150 --> 00:47:54,720 those um from the other stations and 1163 00:47:57,990 --> 00:47:56,160 used to produce 1164 00:47:59,750 --> 00:47:58,000 improved images of the martian surface 1165 00:48:02,150 --> 00:47:59,760 and you've all seen this one the famous 1166 00:48:03,510 --> 00:48:02,160 image 11 which made astronomers very 1167 00:48:05,030 --> 00:48:03,520 very disappointed because they're 1168 00:48:06,549 --> 00:48:05,040 expecting to see burdened forests 1169 00:48:11,109 --> 00:48:06,559 instead they had 1170 00:48:14,309 --> 00:48:12,549 now 1171 00:48:17,829 --> 00:48:14,319 perhaps the most famous mission parks 1172 00:48:19,589 --> 00:48:17,839 was involved in was the was apollo 11. 1173 00:48:21,670 --> 00:48:19,599 no history of parks could be complete 1174 00:48:24,309 --> 00:48:21,680 without a mention of its role 1175 00:48:26,549 --> 00:48:24,319 it began in october 1968 when john 1176 00:48:29,109 --> 00:48:26,559 bolton was visiting caltech he was 1177 00:48:30,630 --> 00:48:29,119 invited to to dinner at the home of bob 1178 00:48:31,589 --> 00:48:30,640 leighton the friend and colleague of 1179 00:48:33,510 --> 00:48:31,599 john's 1180 00:48:34,390 --> 00:48:33,520 and one of the pis for the mariner 4 1181 00:48:36,230 --> 00:48:34,400 mission 1182 00:48:37,670 --> 00:48:36,240 i'm also at the dinner was ed brechton 1183 00:48:39,589 --> 00:48:37,680 the head of the goldstone project and 1184 00:48:41,349 --> 00:48:39,599 during the course of the dinner john was 1185 00:48:43,030 --> 00:48:41,359 asked if you could make available the 1186 00:48:45,589 --> 00:48:43,040 the parks telescope for the upcoming 1187 00:48:47,030 --> 00:48:45,599 apollo 11 mission but in particular for 1188 00:48:49,109 --> 00:48:47,040 those few short hours when the lunar 1189 00:48:51,430 --> 00:48:49,119 module was on the lunar surface and 1190 00:48:53,270 --> 00:48:51,440 because human lives were 1191 00:48:56,309 --> 00:48:53,280 were at risk both he and taffy bowen 1192 00:48:58,549 --> 00:48:56,319 agreed and as he's well known now 600 1193 00:48:59,750 --> 00:48:58,559 million people one-sixth of mankind at 1194 00:49:01,829 --> 00:48:59,760 the time 1195 00:49:04,390 --> 00:49:01,839 witnessed the apollo 11 1196 00:49:05,910 --> 00:49:04,400 moonwalk live on tv through pictures 1197 00:49:07,750 --> 00:49:05,920 received at parks 1198 00:49:09,510 --> 00:49:07,760 the story is far too long for me to go 1199 00:49:11,510 --> 00:49:09,520 into 1200 00:49:13,510 --> 00:49:11,520 detail in this short presentation but i 1201 00:49:15,750 --> 00:49:13,520 i invite you to check the park's website 1202 00:49:18,390 --> 00:49:15,760 and also the honeysuckle creek website 1203 00:49:21,270 --> 00:49:18,400 um for more details on on that 1204 00:49:23,349 --> 00:49:21,280 and um i think um oh yeah it's just that 1205 00:49:25,430 --> 00:49:23,359 there and the beginning of the broadcast 1206 00:49:27,109 --> 00:49:25,440 nasa would just um 1207 00:49:28,549 --> 00:49:27,119 tv is the thing that everyone remembers 1208 00:49:30,390 --> 00:49:28,559 nowadays 1209 00:49:32,470 --> 00:49:30,400 and um 1210 00:49:34,470 --> 00:49:32,480 but at the beginning of the broadcast 1211 00:49:36,230 --> 00:49:34,480 nasa houston was switching between the 1212 00:49:38,150 --> 00:49:36,240 signals being received at goldstone and 1213 00:49:39,829 --> 00:49:38,160 honeysuckle creek when they finally 1214 00:49:41,510 --> 00:49:39,839 switched to parks it was so much better 1215 00:49:43,430 --> 00:49:41,520 they stayed with parks for the remainder 1216 00:49:45,430 --> 00:49:43,440 of the two and a half hour moonwalk and 1217 00:49:46,309 --> 00:49:45,440 just to give you an idea of why they did 1218 00:49:47,829 --> 00:49:46,319 that 1219 00:49:49,589 --> 00:49:47,839 on the right 1220 00:49:51,829 --> 00:49:49,599 outside the left 1221 00:49:53,270 --> 00:49:51,839 you have an image of armstrong 1222 00:49:55,589 --> 00:49:53,280 descending the ladder source from 1223 00:49:57,750 --> 00:49:55,599 goldstone 20 minutes later when they 1224 00:49:59,670 --> 00:49:57,760 were using the parks feed you can see 1225 00:50:02,390 --> 00:49:59,680 aldrin coming down the ladder you can 1226 00:50:04,870 --> 00:50:02,400 see the improvement in the picture 1227 00:50:07,750 --> 00:50:04,880 honeysuckle creek had a had a very good 1228 00:50:10,150 --> 00:50:07,760 image also but because of its um 1229 00:50:12,790 --> 00:50:10,160 smaller size and lower signal to noise 1230 00:50:15,190 --> 00:50:12,800 ratio had a grainier image 1231 00:50:17,030 --> 00:50:15,200 the equivalent picture um 20 minutes 1232 00:50:19,109 --> 00:50:17,040 later when alden was about to step on 1233 00:50:20,710 --> 00:50:19,119 the lunar surface was from parks and 1234 00:50:23,589 --> 00:50:20,720 again you can see the improvement and 1235 00:50:25,430 --> 00:50:23,599 understand why it was involved 1236 00:50:27,430 --> 00:50:25,440 over the years the the we've had a 1237 00:50:30,950 --> 00:50:27,440 mutually beneficial partnership the 1238 00:50:33,349 --> 00:50:30,960 csiro and and nasa whenever parks has 1239 00:50:35,510 --> 00:50:33,359 supported a nation's nasa space mission 1240 00:50:37,270 --> 00:50:35,520 uh we've we've gotten a better radio 1241 00:50:40,150 --> 00:50:37,280 telescope out of it as a result and in 1242 00:50:41,589 --> 00:50:40,160 return nasa has a more capable antenna 1243 00:50:43,829 --> 00:50:41,599 for the next mission that they approach 1244 00:50:45,910 --> 00:50:43,839 us for you can see all the surface 1245 00:50:48,069 --> 00:50:45,920 upgrades and the focus cabin and so on 1246 00:50:50,710 --> 00:50:48,079 we're all funded by by nasa over the 1247 00:50:52,870 --> 00:50:50,720 years and we've got a much much better 1248 00:50:55,910 --> 00:50:52,880 telescope and nasa has a more capable 1249 00:50:57,829 --> 00:50:55,920 antenna for for its next mission also 1250 00:51:00,549 --> 00:50:57,839 so in conclusion i'd like to finish with 1251 00:51:03,109 --> 00:51:00,559 a quote by the us ambassador to 1252 00:51:04,150 --> 00:51:03,119 australia in 2003 when he was at parks 1253 00:51:06,829 --> 00:51:04,160 to 1254 00:51:08,870 --> 00:51:06,839 launch the the mars tracks 1255 00:51:11,270 --> 00:51:08,880 um um 1256 00:51:13,910 --> 00:51:11,280 tom schieffer um 1257 00:51:16,710 --> 00:51:13,920 and basically he said to to quote the 1258 00:51:18,630 --> 00:51:16,720 parks telescope is like a trusted friend 1259 00:51:21,750 --> 00:51:18,640 always there when we need a when we need 1260 00:51:24,150 --> 00:51:21,760 a hand the relationship between csiro 1261 00:51:26,790 --> 00:51:24,160 and nasa is very much like that between 1262 00:51:28,790 --> 00:51:26,800 the united states and australia 1263 00:51:31,109 --> 00:51:28,800 a friend that 1264 00:51:33,510 --> 00:51:31,119 has friends that share common values and 1265 00:51:35,510 --> 00:51:33,520 dreams and i have a picture there of the 1266 00:51:37,430 --> 00:51:35,520 ambassador and the officer in charge of 1267 00:51:38,950 --> 00:51:37,440 the parks telescope john reynolds 1268 00:51:41,109 --> 00:51:38,960 playing a spotted cricket on the dish 1269 00:51:42,549 --> 00:51:41,119 during the opening the ambassador had to 1270 00:51:44,309 --> 00:51:42,559 learn how to hold the cricket back 1271 00:51:46,790 --> 00:51:44,319 correctly he was he thought it was a 1272 00:51:49,270 --> 00:51:46,800 baseball bat at the time but um that it 1273 00:51:51,190 --> 00:51:49,280 worked and just to finish up just 30 1274 00:51:53,030 --> 00:51:51,200 seconds there is an epilogue to the 1275 00:51:56,230 --> 00:51:53,040 story 1276 00:51:58,150 --> 00:51:56,240 on the 27th of august 1962 mariner 2 the 1277 00:51:59,589 --> 00:51:58,160 first interplanetary spacecraft was 1278 00:52:01,109 --> 00:51:59,599 launched to venus 1279 00:52:02,549 --> 00:52:01,119 that just happened to be the day that i 1280 00:52:06,309 --> 00:52:02,559 was born 1281 00:52:10,390 --> 00:52:06,319 okay and when new horizons arrives at 1282 00:52:11,750 --> 00:52:10,400 pluto in july 2015. 1283 00:52:13,910 --> 00:52:11,760 we could say 1284 00:52:16,710 --> 00:52:13,920 in all honesty that in the space of a 1285 00:52:18,470 --> 00:52:16,720 single human lifetime um the entire 1286 00:52:20,470 --> 00:52:18,480 solar system would have been 1287 00:52:21,910 --> 00:52:20,480 explored and i think that's pretty 1288 00:52:40,790 --> 00:52:21,920 impressive and parks was there from the 1289 00:52:47,270 --> 00:52:44,390 but my my serious question is 1290 00:52:49,750 --> 00:52:47,280 i had not realized before actually that 1291 00:52:52,069 --> 00:52:49,760 uh parks was if you will a prototype of 1292 00:52:55,990 --> 00:52:52,079 these large steerable antennas 1293 00:52:57,510 --> 00:52:56,000 and what amazes me is that uh i got it 1294 00:52:59,990 --> 00:52:57,520 right the first time in terms of 1295 00:53:02,630 --> 00:53:00,000 critical things like the the loading on 1296 00:53:04,309 --> 00:53:02,640 the figure of the of the was of the 1297 00:53:06,230 --> 00:53:04,319 telescope was there was there some 1298 00:53:07,750 --> 00:53:06,240 special innovation that 1299 00:53:09,990 --> 00:53:07,760 enabled that or was it just real 1300 00:53:11,910 --> 00:53:10,000 attention to details it was it was 1301 00:53:14,150 --> 00:53:11,920 essentially just the attention to detail 1302 00:53:17,109 --> 00:53:14,160 but also i didn't have time to to go 1303 00:53:19,270 --> 00:53:17,119 into great detail but one of the the the 1304 00:53:20,950 --> 00:53:19,280 engineers that provided the the really 1305 00:53:22,870 --> 00:53:20,960 innovative ideas on how it should be 1306 00:53:24,950 --> 00:53:22,880 done was barnes wallace a famous british 1307 00:53:26,710 --> 00:53:24,960 engineer he was famous during the world 1308 00:53:29,030 --> 00:53:26,720 war during world war ii as the inventor 1309 00:53:31,829 --> 00:53:29,040 of the bouncing bombs and it was his 1310 00:53:33,270 --> 00:53:31,839 idea essentially to to have an out as a 1311 00:53:35,750 --> 00:53:33,280 mounted telescope with the master 1312 00:53:37,349 --> 00:53:35,760 recorder he invented that concept and 1313 00:53:39,510 --> 00:53:37,359 also the spiral purlins he actually 1314 00:53:41,510 --> 00:53:39,520 developed that that idea for the r 100 1315 00:53:43,430 --> 00:53:41,520 airship and the wellington bombers and 1316 00:53:45,270 --> 00:53:43,440 that's what gave the dish that that that 1317 00:53:47,190 --> 00:53:45,280 strength and it's also the reason why 1318 00:53:50,230 --> 00:53:47,200 we've been able to upgrade the surface 1319 00:53:53,030 --> 00:53:50,240 continually over the years and because 1320 00:53:55,190 --> 00:53:53,040 that it did have that strength and um 1321 00:53:57,589 --> 00:53:55,200 and the the designers of the jpl 1322 00:53:59,510 --> 00:53:57,599 antennas were extremely extremely 1323 00:54:01,270 --> 00:53:59,520 interested in that and they 1324 00:54:02,710 --> 00:54:01,280 they took a lot of those design fishes 1325 00:54:04,230 --> 00:54:02,720 as you saw 1326 00:54:05,349 --> 00:54:04,240 and incorporated 1327 00:54:06,309 --> 00:54:05,359 with the 1328 00:54:08,150 --> 00:54:06,319 added 1329 00:54:10,470 --> 00:54:08,160 they have to be able to transmit as well 1330 00:54:12,470 --> 00:54:10,480 as received so they they had a cast of 1331 00:54:13,430 --> 00:54:12,480 grain feed rather than prime focus as we 1332 00:54:16,390 --> 00:54:13,440 do but 1333 00:54:18,150 --> 00:54:16,400 um but it really did come down to the to 1334 00:54:19,430 --> 00:54:18,160 the designers designing it properly at 1335 00:54:20,870 --> 00:54:19,440 the beginning which is why they took 1336 00:54:22,870 --> 00:54:20,880 their time and then built it quickly 1337 00:54:25,030 --> 00:54:22,880 it's a good case of hastening slowly 1338 00:54:26,870 --> 00:54:25,040 where take your time design and then do 1339 00:54:28,390 --> 00:54:26,880 it quickly at the end and of course they 1340 00:54:29,750 --> 00:54:28,400 were the same people that designed the 1341 00:54:32,230 --> 00:54:29,760 sydney harbour bridge and that's still 1342 00:54:33,829 --> 00:54:32,240 up and still will be for a century or
