1 00:00:14,749 --> 00:00:12,049 may 5th 1961 freedom 7 the United States 2 00:00:24,850 --> 00:00:14,759 took the first small step on its journey 3 00:00:31,780 --> 00:00:27,920 America's first man in space Alan 4 00:00:35,750 --> 00:00:31,790 Shepard rode the mercury capsule lifted 5 00:00:41,299 --> 00:00:35,760 216 miles by the Redstone rockets 78,000 6 00:00:44,420 --> 00:00:41,309 pounds of thrust ten years later the 7 00:00:46,880 --> 00:00:44,430 launch vehicle is Saturn five with a 8 00:00:53,210 --> 00:00:46,890 thrust of seven and a half million 9 00:00:55,819 --> 00:00:53,220 pounds on January 31st 1971 the crew of 10 00:00:57,850 --> 00:00:55,829 Apollo 14 would leave Earth on their 11 00:01:00,830 --> 00:00:57,860 mission to the moon 12 00:01:03,200 --> 00:01:00,840 the man who began our first decade of 13 00:01:05,980 --> 00:01:03,210 manned spaceflight would command a 14 00:01:11,060 --> 00:01:05,990 mission that would close that decade 15 00:01:13,310 --> 00:01:11,070 Alan Shepard with him Stuart Roosa who 16 00:01:16,660 --> 00:01:13,320 would orbit the moon alone while Shepard 17 00:01:20,150 --> 00:01:16,670 and Edgar Mitchell explored its surface 18 00:01:24,730 --> 00:01:20,160 their destination a rugged area of lunar 19 00:01:27,499 --> 00:01:24,740 Highlands called fra mauro Apollo 13 20 00:01:31,130 --> 00:01:27,509 aborted as it neared the moon had been 21 00:01:32,499 --> 00:01:31,140 unable to land at this site now we were 22 00:01:37,460 --> 00:01:32,509 trying again 23 00:01:39,350 --> 00:01:37,470 but why fra mauro what happened to the 24 00:01:42,410 --> 00:01:39,360 moon during its first billion years a 25 00:01:43,669 --> 00:01:42,420 period of raised on earth how did the 26 00:01:46,969 --> 00:01:43,679 earth and moon different overall 27 00:01:48,710 --> 00:01:46,979 composition by visiting fra mauro we 28 00:01:51,020 --> 00:01:48,720 hope to sample a very bedrock of the 29 00:01:53,839 --> 00:01:51,030 moon material very different from that 30 00:01:54,919 --> 00:01:53,849 so far collected material perhaps dating 31 00:01:58,249 --> 00:01:54,929 back to the beginning of the solar 32 00:02:00,800 --> 00:01:58,259 system how can you think of the soil 33 00:02:02,449 --> 00:02:00,810 being 4.5 billion years old when igneous 34 00:02:06,529 --> 00:02:02,459 rocks which presumably underlying are 35 00:02:09,919 --> 00:02:06,539 only 3.5 or 3.7 billion years old this I 36 00:02:13,160 --> 00:02:09,929 suppose will be dramatically refuted or 37 00:02:16,130 --> 00:02:13,170 confirmed at the Apollo 14 mission when 38 00:02:19,010 --> 00:02:16,140 they actually visit from our most of the 39 00:02:21,500 --> 00:02:19,020 activity is associated with one place on 40 00:02:24,680 --> 00:02:21,510 the moon and we have tentatively located 41 00:03:12,149 --> 00:02:24,690 that place in or near the crater from 42 00:03:17,080 --> 00:03:14,559 everything went smoothly during Earth 43 00:03:20,830 --> 00:03:17,090 orbit and for the burn that sent Apollo 44 00:03:23,890 --> 00:03:20,840 14 toward the moon then Stuart Roosa 45 00:03:26,190 --> 00:03:23,900 moved the command module Kittyhawk to a 46 00:03:28,869 --> 00:03:26,200 docking with the lunar module Antares 47 00:03:57,250 --> 00:03:28,879 still attached to the third stage of the 48 00:04:00,309 --> 00:03:57,260 booster twice they tried three times as 49 00:04:02,050 --> 00:04:00,319 the astronauts waited an identical 50 00:04:05,199 --> 00:04:02,060 docking probe was brought into Mission 51 00:04:07,869 --> 00:04:05,209 Control this probe on the command module 52 00:04:10,869 --> 00:04:07,879 fits into a funnel-like device on the 53 00:04:13,750 --> 00:04:10,879 lunar module called a drogue tiny 54 00:04:17,080 --> 00:04:13,760 catches on the probes point engaged the 55 00:04:21,610 --> 00:04:17,090 drogue it was these capture latches that 56 00:04:31,570 --> 00:04:21,620 were not holding in space the astronauts 57 00:04:35,790 --> 00:04:31,580 tried a fourth time and a fifth in space 58 00:04:49,670 --> 00:04:35,800 on earth they searched for a solution 59 00:04:54,180 --> 00:04:52,350 as they coasted to the moon the crew 60 00:04:58,260 --> 00:04:54,190 brought the probe inside the spacecraft 61 00:04:59,570 --> 00:04:58,270 for examination on earth the probe was 62 00:05:01,890 --> 00:04:59,580 tested and retested 63 00:05:03,899 --> 00:05:01,900 for we had to be sure that the probe 64 00:05:06,540 --> 00:05:03,909 would work for the most critical docking 65 00:05:11,249 --> 00:05:06,550 as Shepard and Mitchell returned from 66 00:05:17,990 --> 00:05:11,259 the lunar surface on February 4th Apollo 67 00:05:21,689 --> 00:05:18,000 14 went into orbit around the moon as 68 00:05:23,879 --> 00:05:21,699 Apollo 14 was on its first orbit the 69 00:05:27,210 --> 00:05:23,889 third stage of the Boosters smashed into 70 00:05:29,640 --> 00:05:27,220 the moon at its planned target point its 71 00:05:36,779 --> 00:05:29,650 impact picked up by the seismometer left 72 00:05:39,719 --> 00:05:36,789 by Apollo 12 the structure of the moon's 73 00:05:42,990 --> 00:05:39,729 interior is one of the major mysteries 74 00:05:46,309 --> 00:05:43,000 of lunar science now another piece was 75 00:05:48,570 --> 00:05:46,319 added that could help solve the puzzle 76 00:05:51,149 --> 00:05:48,580 later that day Shepard and Mitchell 77 00:06:00,059 --> 00:05:51,159 climbed into the lunar module Antares 78 00:06:01,740 --> 00:06:00,069 and undocked prior to descent but as 79 00:06:05,279 --> 00:06:01,750 they checked out the lunar module a 80 00:06:07,920 --> 00:06:05,289 problem appeared an erroneous abort was 81 00:06:10,920 --> 00:06:07,930 being signaled on board Antares and in 82 00:06:13,769 --> 00:06:10,930 Mission Control should this occur during 83 00:06:16,019 --> 00:06:13,779 the landing burn Antares would abort 84 00:06:19,230 --> 00:06:16,029 automatically and the landing would be 85 00:06:22,409 --> 00:06:19,240 off the Mission Control team had two 86 00:06:25,589 --> 00:06:22,419 hours the time of one lunar orbit to 87 00:06:28,230 --> 00:06:25,599 find a solution flight controller dick 88 00:06:31,800 --> 00:06:28,240 Thorson diagnosed the trouble as a loose 89 00:06:33,629 --> 00:06:31,810 particle in the abort button the burden 90 00:06:35,070 --> 00:06:33,639 then came to rest on the shoulders of 91 00:06:37,040 --> 00:06:35,080 computer programmer 92 00:06:39,650 --> 00:06:37,050 Donald Isles 93 00:06:43,040 --> 00:06:39,660 working against time at MIT in Cambridge 94 00:06:45,529 --> 00:06:43,050 Massachusetts he reprogrammed the lunar 95 00:06:49,430 --> 00:06:45,539 module computer to ignore the false 96 00:06:54,110 --> 00:06:49,440 signal this new program was then checked 97 00:06:56,210 --> 00:06:54,120 out in a simulator at Cape Kennedy as 98 00:06:58,520 --> 00:06:56,220 antarious came into contact with earth 99 00:07:07,580 --> 00:06:58,530 again the instructions were sent up to 100 00:07:10,339 --> 00:07:07,590 the crew less than 10 miles above the 101 00:07:21,290 --> 00:07:10,349 lunar surface Shepard and Mitchell swept 102 00:07:24,680 --> 00:07:21,300 across the landing site then another 103 00:07:26,450 --> 00:07:24,690 problem the landing radar which would 104 00:07:31,320 --> 00:07:26,460 tell them their altitude above the lunar 105 00:07:36,689 --> 00:07:35,100 aboard radar there is that you would 106 00:08:08,850 --> 00:07:36,699 like you to cycle the landing radar 107 00:08:11,839 --> 00:08:08,860 breaker okay okay cone crater a major 108 00:08:14,999 --> 00:08:11,849 objective of this mission to Fra Mauro a 109 00:08:18,330 --> 00:08:15,009 hole blasted in the moon's surface eons 110 00:08:20,760 --> 00:08:18,340 ago it could provide a scientific clue 111 00:08:30,270 --> 00:08:20,770 for the history of the men for the earth 112 00:08:34,510 --> 00:08:32,830 we think that the fra mauro area was 113 00:08:36,490 --> 00:08:34,520 formed from materials thrown out by the 114 00:08:39,790 --> 00:08:36,500 impact that created the Imbrium basin to 115 00:08:41,950 --> 00:08:39,800 the north if this is the case we could 116 00:08:45,430 --> 00:08:41,960 get samples torn out from the deep of 60 117 00:08:47,290 --> 00:08:45,440 miles in the lunar crust all in all the 118 00:08:48,820 --> 00:08:47,300 from our material should contain a great 119 00:08:51,310 --> 00:08:48,830 deal of new information about the early 120 00:08:52,780 --> 00:08:51,320 history of the moon and thus help us to 121 00:09:01,690 --> 00:08:52,790 better understand the formation of our 122 00:09:06,460 --> 00:09:03,820 hey I can give it a few flakes to 123 00:09:09,040 --> 00:09:06,470 through two hundred feet until I have a 124 00:09:12,460 --> 00:09:09,050 per second that looks good mental here 125 00:09:14,080 --> 00:09:12,470 I predict you look great 126 00:09:18,610 --> 00:09:14,090 okay look like you're going right over 127 00:09:23,100 --> 00:09:18,620 there metal of birth Triplett 270 feet 128 00:09:31,450 --> 00:09:27,040 okay solid you're just barely from the 129 00:09:33,940 --> 00:09:31,460 moisture barely conscious it could land 130 00:09:37,780 --> 00:09:33,950 over here there's some stuff out god 131 00:09:43,680 --> 00:09:37,790 you're old you down right now okay third 132 00:09:49,210 --> 00:09:43,690 good rhodium looking great sixty Seconds 133 00:09:54,160 --> 00:09:49,220 forty feet three feet per second 30 feet 134 00:10:10,660 --> 00:10:07,030 the second contact five-and-a-half hours 135 00:10:18,730 --> 00:10:10,670 later Shepard left the lunar module to 136 00:10:23,470 --> 00:10:18,740 begin the first of two explorations ten 137 00:10:27,010 --> 00:10:23,480 years later 114 hours 22 minutes after 138 00:10:31,150 --> 00:10:27,020 leaving Earth Alan Shepard stepped onto 139 00:10:44,770 --> 00:10:31,160 the moon it looks like you're about on 140 00:10:46,540 --> 00:10:44,780 the bottom step and on the surface four 141 00:10:53,749 --> 00:10:46,550 minutes later he was joined by Ed 142 00:10:58,739 --> 00:10:55,949 following the tradition of two previous 143 00:11:09,619 --> 00:10:58,749 missions Shepard and Mitchell planted 144 00:11:15,389 --> 00:11:12,569 the next job was to load the met a 145 00:11:17,220 --> 00:11:15,399 rickshaw like wagon the astronauts would 146 00:11:22,259 --> 00:11:17,230 use to transport their tools of 147 00:11:24,269 --> 00:11:22,269 exploration and collected samples one of 148 00:11:27,869 --> 00:11:24,279 the big factors in lunar exploration is 149 00:11:30,449 --> 00:11:27,879 mobility in Apollo 14 we had the met 150 00:11:33,389 --> 00:11:30,459 which let us move further afield in the 151 00:11:35,970 --> 00:11:33,399 previous two missions in future missions 152 00:11:39,269 --> 00:11:35,980 we'll use the lunar rover a sort of moon 153 00:11:40,979 --> 00:11:39,279 going dune buggie this mobility will 154 00:11:42,509 --> 00:11:40,989 mean less time spending getting from 155 00:11:54,929 --> 00:11:42,519 here to there and more time collecting 156 00:11:56,939 --> 00:11:54,939 scientific data Shepard pulled the met 157 00:11:59,609 --> 00:11:56,949 while Mitchell carried the bar bell 158 00:12:02,090 --> 00:11:59,619 shaped package containing an automatic 159 00:12:04,259 --> 00:12:02,100 scientific station they would assemble a 160 00:12:07,590 --> 00:12:04,269 station designed to continue 161 00:12:40,560 --> 00:12:07,600 broadcasting data to earth for a year 162 00:12:44,890 --> 00:12:43,030 finding a suitable site to place the 163 00:12:47,680 --> 00:12:44,900 scientific instruments was the next 164 00:12:49,630 --> 00:12:47,690 order of business Shepard and Mitchell 165 00:12:55,000 --> 00:12:49,640 now began setting up the automated 166 00:12:58,870 --> 00:12:55,010 scientific laboratory a small nuclear 167 00:13:02,220 --> 00:12:58,880 generator to power the array the Central 168 00:13:04,810 --> 00:13:02,230 Station to transmit data to earth a 169 00:13:10,300 --> 00:13:04,820 seismometer to detect and measure 170 00:13:12,880 --> 00:13:10,310 activity on and within the moon a series 171 00:13:16,620 --> 00:13:12,890 of three experiments to measure charged 172 00:13:19,720 --> 00:13:16,630 particles near the lunar surface an 173 00:13:23,080 --> 00:13:19,730 independent experiment to reflect laser 174 00:13:25,120 --> 00:13:23,090 beams from Earth enabling extremely 175 00:13:28,180 --> 00:13:25,130 precise measurements of such things as 176 00:13:31,500 --> 00:13:28,190 earth to moon distance the wobble of the 177 00:13:36,460 --> 00:13:31,510 Earth's axis continental drift and 178 00:13:38,530 --> 00:13:36,470 shifts of the Earth's crust and a mortar 179 00:13:42,280 --> 00:13:38,540 to be fired by a signal from Earth 180 00:13:44,020 --> 00:13:42,290 sometime within the next year the impact 181 00:13:47,540 --> 00:13:44,030 of its charges would be picked up by 182 00:13:51,079 --> 00:13:47,550 Apollo 14 seismometer 183 00:13:53,660 --> 00:13:51,089 as a final exercise Mitchell used the 184 00:13:57,290 --> 00:13:53,670 thumper a device to explode a series of 185 00:13:59,840 --> 00:13:57,300 controlled shotgun like charges the 186 00:14:02,180 --> 00:13:59,850 vibrations from these detonations were 187 00:14:06,110 --> 00:14:02,190 picked up by a series of instruments he 188 00:14:08,600 --> 00:14:06,120 had previously deployed with the 189 00:14:11,210 --> 00:14:08,610 instruments set up and operating they 190 00:14:16,940 --> 00:14:11,220 headed back toward Antares pausing on 191 00:14:19,340 --> 00:14:16,950 the way to collect samples they loaded 192 00:14:21,590 --> 00:14:19,350 their 44 pounds of lunar material aboard 193 00:14:24,620 --> 00:14:21,600 the lunar module and after four hours 194 00:14:28,850 --> 00:14:24,630 and 50 minutes on the surface climbed 195 00:14:35,630 --> 00:14:33,320 as Shepard and Mitchell rested Stuart 196 00:14:41,690 --> 00:14:35,640 Roosa continued his work from lunar 197 00:14:47,490 --> 00:14:44,610 his photographs would have meaning not 198 00:14:49,200 --> 00:14:47,500 only to the scientific community but 199 00:15:00,630 --> 00:14:49,210 would have direct bearing on the 200 00:15:03,000 --> 00:15:00,640 planning for coming missions 12 hours 40 201 00:15:16,000 --> 00:15:03,010 minutes later Shepard and Mitchell began 202 00:15:20,690 --> 00:15:18,170 after loading the lunar rickshaw 203 00:15:25,340 --> 00:15:20,700 mitchell began the journey to cone 204 00:15:58,489 --> 00:15:25,350 crater Shepard adjusted the television 205 00:16:04,979 --> 00:16:02,340 point a the first stop on the trip to 206 00:16:07,319 --> 00:16:04,989 comb here they would collect and 207 00:16:10,139 --> 00:16:07,329 document samples measure the local 208 00:16:24,289 --> 00:16:10,149 magnetic field and take core tube 209 00:16:29,400 --> 00:16:26,699 the quality of the scientific 210 00:16:32,129 --> 00:16:29,410 description by the astronauts could be 211 00:16:34,489 --> 00:16:32,139 termed by earth-based scientists only as 212 00:16:37,669 --> 00:16:34,499 excellent 213 00:16:40,590 --> 00:16:37,679 but now Shepard and Mitchell pushed on 214 00:16:43,679 --> 00:16:40,600 after a brief stop at a second survey 215 00:16:46,619 --> 00:16:43,689 site they began their assault on cone 216 00:16:49,319 --> 00:16:46,629 crater a climb not only toward the 217 00:16:54,479 --> 00:16:49,329 summit of a lunar mountain but back 218 00:16:57,030 --> 00:16:54,489 through time a large crater acts in many 219 00:16:59,059 --> 00:16:57,040 respects like a drill throwing out 220 00:17:01,439 --> 00:16:59,069 material from deep beneath the surface 221 00:17:03,720 --> 00:17:01,449 this material should be very different 222 00:17:05,519 --> 00:17:03,730 from any we've collected before perhaps 223 00:17:12,670 --> 00:17:05,529 dating back to the origins of the moon 224 00:17:12,680 --> 00:17:22,780 permanent point but indefinitely uphill 225 00:17:28,460 --> 00:17:25,400 how do I pull up the sizes big trader 226 00:17:31,700 --> 00:17:28,470 came take a break get the map find out 227 00:17:33,680 --> 00:17:31,710 exactly where we are the maps they were 228 00:17:37,250 --> 00:17:33,690 using had been made from photography 229 00:17:40,100 --> 00:17:37,260 from lunar orbit the hummert's craters 230 00:18:54,250 --> 00:17:40,110 ridges and boulders took on a new 231 00:18:59,270 --> 00:18:56,740 now they were working against time 232 00:19:01,549 --> 00:18:59,280 against the oxygen and water left in 233 00:19:04,850 --> 00:19:01,559 their backpacks against the alien 234 00:19:53,209 --> 00:19:04,860 terrain top orig thinking it's the rim 235 00:19:58,709 --> 00:19:55,919 standing in a boulder field surrounded 236 00:20:00,779 --> 00:19:58,719 by rocks 10 to 12 feet long the 237 00:20:03,839 --> 00:20:00,789 astronauts made their most difficult 238 00:20:07,169 --> 00:20:03,849 decision with the concurrence of Mission 239 00:20:10,469 --> 00:20:07,179 Control they stopped their climb less 240 00:20:15,529 --> 00:20:10,479 than 150 feet from the edge to begin the 241 00:20:20,729 --> 00:20:18,180 the crew had no way of realizing they 242 00:20:21,930 --> 00:20:20,739 were so close it was a week after the 243 00:20:26,459 --> 00:20:21,940 mission before we determine this by 244 00:20:29,039 --> 00:20:26,469 photographic analysis while they could 245 00:20:31,229 --> 00:20:29,049 overcome the terrain they could not beat 246 00:20:34,229 --> 00:20:31,239 the steady drain of oxygen from their 247 00:20:36,869 --> 00:20:34,239 backpacks in the terms of scientific 248 00:20:41,159 --> 00:20:36,879 meaning the decision not to go on to the 249 00:21:00,359 --> 00:20:41,169 rim meant little in human terms a great 250 00:21:02,129 --> 00:21:00,369 disappointment the white rock is of 251 00:21:04,979 --> 00:21:02,139 different composition to the Apollo 11 252 00:21:06,180 --> 00:21:04,989 and 12 rocks in fact the chemistry of 253 00:21:08,719 --> 00:21:06,190 all the rocks that are being looked at 254 00:21:10,799 --> 00:21:08,729 so far is different to those rocks 255 00:21:12,509 --> 00:21:10,809 potassium and uranium are 10 times 256 00:21:14,219 --> 00:21:12,519 higher which are the sort of values we 257 00:21:16,799 --> 00:21:14,229 might expect if the firm are rocks 258 00:21:20,230 --> 00:21:16,809 represent ancient lunar crust which of 259 00:21:39,360 --> 00:21:23,530 again it was time time to head back to 260 00:21:43,950 --> 00:21:41,760 after a quick side trip to check on the 261 00:21:46,590 --> 00:21:43,960 science station they loaded the lunar 262 00:21:49,200 --> 00:21:46,600 module with samples and data and stepped 263 00:21:51,960 --> 00:21:49,210 off the lunar surface the second 264 00:21:55,650 --> 00:21:51,970 expedition had lasted four hours and 35 265 00:22:01,110 --> 00:21:55,660 minutes a total exploration of a record 266 00:22:03,810 --> 00:22:01,120 nine and one-half hours thirty three and 267 00:22:06,000 --> 00:22:03,820 a half hours after they landed Alan 268 00:22:34,070 --> 00:22:06,010 Shepard and Edgar Mitchell lifted off in 269 00:22:34,080 --> 00:22:41,220 Oh baby it's the record 270 00:22:45,930 --> 00:22:44,010 doing up good use 271 00:22:51,120 --> 00:22:45,940 Roger you're looking good from down here 272 00:22:53,760 --> 00:22:51,130 up on one minute half an hour later 273 00:23:10,890 --> 00:22:53,770 Stuart Roosa watched their progress from 274 00:23:15,030 --> 00:23:13,470 is an anticipation gaming it about 275 00:23:16,920 --> 00:23:15,040 Arthur speed closing in a little more 276 00:23:30,090 --> 00:23:16,930 for the pictures of the service module 277 00:23:39,060 --> 00:23:30,100 of Khmer mighdal okay okay it's food and 278 00:23:45,650 --> 00:23:39,070 around we go ohhh oh you look good there 279 00:23:45,660 --> 00:23:50,810 rope 280 00:23:59,870 --> 00:23:57,920 would you believe 360,000 yeah Kenny 281 00:24:02,960 --> 00:23:59,880 Arkansas an extremely smooth loop we're 282 00:24:08,840 --> 00:24:02,970 sitting at the 70 feet watching him go 283 00:24:11,600 --> 00:24:08,850 around he looks very clean the 284 00:24:32,979 --> 00:24:11,610 inspection complete Antares and Kitty 285 00:24:41,599 --> 00:24:38,799 and we got a hard dock big fire breather 286 00:24:43,759 --> 00:24:41,609 they transferred the gear from Antares 287 00:24:47,060 --> 00:24:43,769 to Kittyhawks buttoned up the tunnel 288 00:24:48,649 --> 00:24:47,070 then jettison the lunar module it would 289 00:24:51,649 --> 00:24:48,659 crash into the moon at a predetermined 290 00:24:54,709 --> 00:24:51,659 spot its impact picked up by their 291 00:25:00,379 --> 00:24:54,719 seismometer and the seismometer left by 292 00:25:02,239 --> 00:25:00,389 Apollo 12 over a year earlier a hundred 293 00:25:04,969 --> 00:25:02,249 and forty nine hours after they left 294 00:25:09,049 --> 00:25:04,979 Earth they performed the burn that broke 295 00:25:11,029 --> 00:25:09,059 them out of lunar orbit during the coast 296 00:25:14,389 --> 00:25:11,039 to earth there would be time to catch up 297 00:25:20,779 --> 00:25:14,399 on sleep relax and do all the little 298 00:25:23,509 --> 00:25:20,789 things left undone and there was one 299 00:25:25,839 --> 00:25:23,519 more item a series of scientific 300 00:25:28,190 --> 00:25:25,849 demonstrations in zero gravity 301 00:25:32,569 --> 00:25:28,200 demonstrations impossible to reproduce 302 00:25:34,129 --> 00:25:32,579 on earth these trials looked at basic 303 00:25:37,190 --> 00:25:34,139 physical properties of matter in 304 00:25:40,339 --> 00:25:37,200 zero-gravity studies that could lead 305 00:25:45,680 --> 00:25:40,349 eventually to new materials manufactured 306 00:25:49,669 --> 00:25:45,690 in space for use on earth on February 307 00:25:52,489 --> 00:25:49,679 9th 1971 nine days after they left Earth 308 00:25:55,419 --> 00:25:52,499 the crew of Apollo 14 hit the atmosphere 309 00:25:57,940 --> 00:25:55,429 of their planet at a speed of over 310 00:26:01,459 --> 00:25:57,950 24,000 miles per hour 311 00:26:05,599 --> 00:26:01,469 they hurtled toward Earth a meteor 312 00:26:12,470 --> 00:26:05,609 heading home on board 95 pounds of the 313 00:26:16,260 --> 00:26:14,520 extremely important those relate to the 314 00:26:19,230 --> 00:26:16,270 question of why we while we're fooling 315 00:26:21,450 --> 00:26:19,240 around the loan it's really that the the 316 00:26:23,520 --> 00:26:21,460 imprint of history of solar system 317 00:26:24,690 --> 00:26:23,530 history on the earth-moon system is 318 00:26:31,400 --> 00:26:24,700 centered on the moon for the first 319 00:26:36,600 --> 00:26:33,990 what do we hope to gain is we've got a 320 00:26:38,549 --> 00:26:36,610 window right now between T equals zero 321 00:26:41,040 --> 00:26:38,559 the beginning of the solar system and 322 00:26:43,370 --> 00:26:41,050 when the earth so totally messed up 323 00:26:46,799 --> 00:26:43,380 itself that we can't look at it anymore 324 00:26:54,330 --> 00:26:46,809 we'd like to look in there and that 325 00:26:56,180 --> 00:26:54,340 windows on the moon Apollo 14 has 326 00:26:58,880 --> 00:26:56,190 already had a very big scientific impact 327 00:27:01,200 --> 00:26:58,890 and we still have three missions left 328 00:27:05,630 --> 00:27:01,210 they'll be heading into even more rugged 329 00:27:10,860 --> 00:27:09,000 beginning with Apollo 15 the lunar rover 330 00:27:13,560 --> 00:27:10,870 will let us range further afield and 331 00:27:21,390 --> 00:27:13,570 collect more and more very percent of 332 00:27:23,640 --> 00:27:21,400 examples and information the study of 333 00:27:24,870 --> 00:27:23,650 the moon and how for instance elements 334 00:27:27,600 --> 00:27:24,880 and minerals are distributed in its 335 00:27:29,960 --> 00:27:27,610 crust will enable us to learn more about 336 00:27:32,250 --> 00:27:29,970 the process of crest formation on earth 337 00:27:33,990 --> 00:27:32,260 leading to a better understanding of the 338 00:27:37,530 --> 00:27:34,000 way that certain elements concentrate in 339 00:27:39,000 --> 00:27:37,540 the crust will we have had enough 340 00:27:42,780 --> 00:27:39,010 missions to the moon by the end of the 341 00:27:44,880 --> 00:27:42,790 Apollo program probably not you can
