1 00:00:23,850 --> 00:00:20,820 hello everyone I'm gay hill and I am in 2 00:00:26,580 --> 00:00:23,860 Grail Mission Control we are with the 3 00:00:30,330 --> 00:00:26,590 team for its last half hour with the 4 00:00:33,810 --> 00:00:30,340 spacecraft and ebb and flow are now out 5 00:00:36,090 --> 00:00:33,820 of fuel and they are on a delivered 6 00:00:38,549 --> 00:00:36,100 collision course with the moon and they 7 00:00:43,200 --> 00:00:38,559 will impact the moon at approximately 8 00:00:47,009 --> 00:00:43,210 3,800 miles per hour for ebb the impact 9 00:00:50,310 --> 00:00:47,019 will take place at approximately 220 846 10 00:00:55,170 --> 00:00:50,320 pacific time and then for flow about 20 11 00:00:57,840 --> 00:00:55,180 to 30 seconds later at about 20 to 29 14 12 00:01:00,390 --> 00:00:57,850 give or take a few seconds we're going 13 00:01:03,180 --> 00:01:00,400 to spend the next half hour talking two 14 00:01:05,460 --> 00:01:03,190 team members about this project and what 15 00:01:07,980 --> 00:01:05,470 has been like beginning with David 16 00:01:10,830 --> 00:01:07,990 layman he is the project manager of 17 00:01:13,410 --> 00:01:10,840 Grail first of all let's talk about the 18 00:01:17,039 --> 00:01:13,420 last big event the burn and that 19 00:01:20,250 --> 00:01:17,049 happened about 20 odd minutes ago what 20 00:01:22,020 --> 00:01:20,260 happened at that time well about 20 21 00:01:24,360 --> 00:01:22,030 minutes ago as you said we just finished 22 00:01:28,020 --> 00:01:24,370 the burn to depletion on both spacecraft 23 00:01:30,060 --> 00:01:28,030 both ebb and flow and you can see the 24 00:01:32,730 --> 00:01:30,070 display up there you which is the 25 00:01:36,060 --> 00:01:32,740 Doppler signal and it shows that on the 26 00:01:38,400 --> 00:01:36,070 edge spacecraft the amount of fuel 27 00:01:42,240 --> 00:01:38,410 remaining was equal to approximately 20 28 00:01:45,210 --> 00:01:42,250 meters per second and then on flow the 29 00:01:47,100 --> 00:01:45,220 remaining fuel was Aklavik to 25 meters 30 00:01:50,250 --> 00:01:47,110 per second you know why was it necessary 31 00:01:53,040 --> 00:01:50,260 to do this experiment this exercise you 32 00:01:55,170 --> 00:01:53,050 wanted to gain information right down to 33 00:01:58,430 --> 00:01:55,180 the very last right right what we wanted 34 00:02:01,440 --> 00:01:58,440 to do is we're going to use this data to 35 00:02:04,110 --> 00:02:01,450 compare with estimates of what the fuel 36 00:02:05,910 --> 00:02:04,120 remaining is and so it's a very rare for 37 00:02:07,950 --> 00:02:05,920 a mission to be able to do a burn to 38 00:02:09,690 --> 00:02:07,960 depletion that tells you exactly how 39 00:02:12,089 --> 00:02:09,700 much fuel is remaining we're gonna use 40 00:02:13,860 --> 00:02:12,099 that data to compare to the estimates 41 00:02:16,380 --> 00:02:13,870 the engineers have and then we can use 42 00:02:18,930 --> 00:02:16,390 that to better manage future missions to 43 00:02:21,809 --> 00:02:18,940 help other missions blow tell me why we 44 00:02:23,940 --> 00:02:21,819 decided to end the mission this way why 45 00:02:29,430 --> 00:02:23,950 not just let the fuel 46 00:02:32,040 --> 00:02:29,440 be done and land wherever well on the 47 00:02:34,380 --> 00:02:32,050 moon there are about 23 heritage 48 00:02:37,619 --> 00:02:34,390 historical sites and these are sites 49 00:02:42,030 --> 00:02:37,629 where either the US or the Russians have 50 00:02:43,979 --> 00:02:42,040 a soft Lander and the NASA policy is to 51 00:02:46,199 --> 00:02:43,989 not to disturb those sites to stay 52 00:02:48,509 --> 00:02:46,209 within to say outside of two kilometers 53 00:02:50,059 --> 00:02:48,519 so we wanted to miss those sites the 54 00:02:52,890 --> 00:02:50,069 other thing is we wanted to know exactly 55 00:02:55,530 --> 00:02:52,900 where we landed or where we're going to 56 00:02:58,500 --> 00:02:55,540 crash and so we're coming up from the 57 00:03:02,130 --> 00:02:58,510 south and we want to get good tracking 58 00:03:04,140 --> 00:03:02,140 data of the final moments and then we're 59 00:03:06,449 --> 00:03:04,150 going to crash on the North the northern 60 00:03:08,759 --> 00:03:06,459 hemisphere of the moon so we wanted lots 61 00:03:11,130 --> 00:03:08,769 of data tracking data to know where we 62 00:03:14,670 --> 00:03:11,140 actually crash now we have visuals and 63 00:03:17,490 --> 00:03:14,680 animation showing exactly the trajectory 64 00:03:20,430 --> 00:03:17,500 of the two spacecraft walk us through 65 00:03:22,979 --> 00:03:20,440 what will be happening and we can 66 00:03:26,309 --> 00:03:22,989 actually see that animation and we can 67 00:03:32,160 --> 00:03:26,319 go ahead and take a look at it it will 68 00:03:34,830 --> 00:03:32,170 start on a globe view here we go all 69 00:03:37,460 --> 00:03:34,840 right so this is Evan flow I one leads 70 00:03:39,720 --> 00:03:37,470 the other by about 20 seconds and 71 00:03:42,210 --> 00:03:39,730 they're going to be coming up from from 72 00:03:43,500 --> 00:03:42,220 the southern hemisphere and they're 73 00:03:48,780 --> 00:03:43,510 already about half way there right now 74 00:03:51,500 --> 00:03:48,790 and about to 28 p.m. but we're actually 75 00:03:57,470 --> 00:03:51,510 going to do the the impact on the moon 76 00:04:00,870 --> 00:03:57,480 and there you have it and tell me why 77 00:04:02,789 --> 00:04:00,880 took this location that it's going to be 78 00:04:04,890 --> 00:04:02,799 in darkness we won't be able to see 79 00:04:07,170 --> 00:04:04,900 anything will we we won't be able to see 80 00:04:10,349 --> 00:04:07,180 anything because it is dark right now on 81 00:04:12,780 --> 00:04:10,359 the moon but we picked a site to make 82 00:04:16,589 --> 00:04:12,790 sure that we did not hit the historic 83 00:04:18,839 --> 00:04:16,599 sites the Heritage historic sites and we 84 00:04:20,789 --> 00:04:18,849 wanted to get good tracking data before 85 00:04:24,270 --> 00:04:20,799 we impacted and so it turns out that 86 00:04:26,550 --> 00:04:24,280 this mountain and then 75 degrees north 87 00:04:28,500 --> 00:04:26,560 latitude is is where it fell out when 88 00:04:30,870 --> 00:04:28,510 we're going to hit perhaps we will be 89 00:04:33,839 --> 00:04:30,880 able to see it right now but LRO is 90 00:04:35,040 --> 00:04:33,849 orbiting the moon will we be able to get 91 00:04:38,070 --> 00:04:35,050 information 92 00:04:40,469 --> 00:04:38,080 later on yes LRO has already imaged this 93 00:04:42,240 --> 00:04:40,479 site in detail we have lots of data on 94 00:04:44,100 --> 00:04:42,250 where we're going to impact and then in 95 00:04:46,260 --> 00:04:44,110 a couple weeks lrl will fly over it 96 00:04:48,240 --> 00:04:46,270 again the lunar reconnaissance orbiter 97 00:04:50,640 --> 00:04:48,250 and we'll get more data on what we'll 98 00:04:53,219 --> 00:04:50,650 see well would just be looking at it 99 00:04:55,499 --> 00:04:53,229 with optical sort of instruments or 100 00:04:57,119 --> 00:04:55,509 we'll be looking at it in infrared was 101 00:04:59,430 --> 00:04:57,129 sort of interesting had a full spectrum 102 00:05:01,800 --> 00:04:59,440 of instruments so all kinds of spectrum 103 00:05:04,589 --> 00:05:01,810 they'll be able to image well overall 104 00:05:06,659 --> 00:05:04,599 looking back at this mission you said 105 00:05:09,240 --> 00:05:06,669 yourself that you would have mixed 106 00:05:12,029 --> 00:05:09,250 feelings today why is that well we've 107 00:05:14,399 --> 00:05:12,039 been we launched 15 months ago the 108 00:05:15,869 --> 00:05:14,409 spacecraft were very well behaved what 109 00:05:17,369 --> 00:05:15,879 I'd like to do is continue on for 110 00:05:20,100 --> 00:05:17,379 another six months but that's not going 111 00:05:21,959 --> 00:05:20,110 to happen so it's pretty much a sad day 112 00:05:23,309 --> 00:05:21,969 for me in fact I'm wearing usually I 113 00:05:24,869 --> 00:05:23,319 don't have handkerchiefs with me but 114 00:05:26,640 --> 00:05:24,879 today I brought my handkerchief just in 115 00:05:28,350 --> 00:05:26,650 case you're gonna be ready but this 116 00:05:31,589 --> 00:05:28,360 mission has surprised a lot of people 117 00:05:34,350 --> 00:05:31,599 it's gone well beyond what everyone's 118 00:05:36,450 --> 00:05:34,360 expectations were having not yes we've 119 00:05:38,939 --> 00:05:36,460 all all of the data we hope to have 120 00:05:40,800 --> 00:05:38,949 gotten scientifically we've gotten over 121 00:05:43,559 --> 00:05:40,810 ninety-nine point nine nine percent of 122 00:05:46,740 --> 00:05:43,569 the data available we have and the 123 00:05:49,170 --> 00:05:46,750 team's done a great job and we did it on 124 00:05:51,480 --> 00:05:49,180 schedule and under budget alright so 125 00:05:54,510 --> 00:05:51,490 we're not too far off in the big moment 126 00:05:57,300 --> 00:05:54,520 thanks for helping us out Dave right now 127 00:06:00,600 --> 00:05:57,310 let's we're less than 25 minutes away 128 00:06:02,670 --> 00:06:00,610 from Impact again the time is 228 129 00:06:05,519 --> 00:06:02,680 pacific time five to twenty eight 130 00:06:07,830 --> 00:06:05,529 eastern time and since the very 131 00:06:10,490 --> 00:06:07,840 beginning this mission has always been 132 00:06:13,070 --> 00:06:10,500 all about the science now the 133 00:06:16,230 --> 00:06:13,080 spacecraft's were flying at about 55 134 00:06:19,050 --> 00:06:16,240 kilometers over the surface and be they 135 00:06:22,830 --> 00:06:19,060 were able to return the best gravity map 136 00:06:25,469 --> 00:06:22,840 ever of any celestial body and then for 137 00:06:28,050 --> 00:06:25,479 an encore the twins went ahead and went 138 00:06:34,029 --> 00:06:28,060 even lower here's a look at some of the 139 00:06:38,029 --> 00:06:34,039 accomplishments of this mission 32 140 00:06:41,050 --> 00:06:38,039 zero and liftoff of the Delta 2 with 141 00:06:43,999 --> 00:06:41,060 grail Jerry to the center of the boat 142 00:06:45,680 --> 00:06:44,009 when gray launched at that point I was 143 00:06:47,839 --> 00:06:45,690 hoping we would get those two spacecraft 144 00:06:50,570 --> 00:06:47,849 interpreter on the moon we have 145 00:06:54,159 --> 00:06:50,580 grayleigh breakwire and separation good 146 00:06:56,809 --> 00:06:54,169 separation grill a now flying on its own 147 00:07:00,589 --> 00:06:56,819 ok I'll stations Grilli systems on grill 148 00:07:02,800 --> 00:07:00,599 a court at this time the reconfiguration 149 00:07:15,200 --> 00:07:02,810 of the spacecraft for the post LOI 150 00:07:18,080 --> 00:07:15,210 configuration has begun we look like 151 00:07:20,150 --> 00:07:18,090 they're in a very nominal orbit things 152 00:07:22,760 --> 00:07:20,160 have gone as as well as they could 153 00:07:24,800 --> 00:07:22,770 possibly have gone neither spacecraft 154 00:07:27,350 --> 00:07:24,810 has had an upset that has caused it to 155 00:07:29,899 --> 00:07:27,360 go into safe mode we have not lost any 156 00:07:33,499 --> 00:07:29,909 data we have essentially collected more 157 00:07:35,809 --> 00:07:33,509 than ninety-nine point nine nine percent 158 00:07:38,510 --> 00:07:35,819 of the data so in both the quantity and 159 00:07:40,339 --> 00:07:38,520 the quality and the spatial resolution 160 00:07:42,620 --> 00:07:40,349 of the data and the amount of data 161 00:07:45,770 --> 00:07:42,630 everything has exceeded the expectations 162 00:07:48,320 --> 00:07:45,780 that we had for the mission one of the 163 00:07:52,310 --> 00:07:48,330 biggest surprises that we've found so 164 00:07:55,670 --> 00:07:52,320 far is evidence for very long dykes or 165 00:07:58,180 --> 00:07:55,680 intrusive features within the crust that 166 00:08:00,730 --> 00:07:58,190 are not observed at the surface 167 00:08:04,250 --> 00:08:00,740 whatsoever 168 00:08:06,950 --> 00:08:04,260 heated up enough to expand and that this 169 00:08:10,730 --> 00:08:06,960 occurred extremely early after the moon 170 00:08:14,270 --> 00:08:10,740 formed we now see evidence for this we 171 00:08:17,510 --> 00:08:14,280 have found with the Grail data that the 172 00:08:19,610 --> 00:08:17,520 crust of the womb is even thinner than 173 00:08:22,700 --> 00:08:19,620 it was believed to be and so this 174 00:08:26,240 --> 00:08:22,710 provides us with information about how 175 00:08:28,280 --> 00:08:26,250 much early melting of the lunar exterior 176 00:08:30,260 --> 00:08:28,290 occurred and how much of the outside of 177 00:08:32,719 --> 00:08:30,270 the moon melted so it tells us something 178 00:08:35,839 --> 00:08:32,729 about the thermal history but it also 179 00:08:38,570 --> 00:08:35,849 tells us about how this melting was 180 00:08:41,540 --> 00:08:38,580 distributed over the surface of the Moon 181 00:08:44,480 --> 00:08:41,550 and we've been able to map this out the 182 00:08:47,660 --> 00:08:44,490 idea that one can map a planet from 183 00:08:49,610 --> 00:08:47,670 orbit at the height you know similar to 184 00:08:52,910 --> 00:08:49,620 what a commercial airplane flies around 185 00:08:56,420 --> 00:08:52,920 earth just opens up huge possibilities 186 00:08:59,450 --> 00:08:56,430 of really studying the shallow structure 187 00:09:01,790 --> 00:08:59,460 of the moon our team is absolutely 188 00:09:04,730 --> 00:09:01,800 delighted that we now have the data set 189 00:09:07,010 --> 00:09:04,740 that is going to allow scientists to 190 00:09:09,920 --> 00:09:07,020 study these fascinating questions for 191 00:09:13,010 --> 00:09:09,930 years to come ok we have scooched over 192 00:09:15,770 --> 00:09:13,020 to Maria Zuber spot she is the principal 193 00:09:18,260 --> 00:09:15,780 investigator she's standing by watching 194 00:09:21,050 --> 00:09:18,270 all this information come in you 195 00:09:24,890 --> 00:09:21,060 yourself said in that video piece that 196 00:09:27,130 --> 00:09:24,900 it exceeded all your expectations this 197 00:09:31,040 --> 00:09:27,140 has gone as well as it possibly have 198 00:09:33,140 --> 00:09:31,050 good of God it's it's actually hard for 199 00:09:36,470 --> 00:09:33,150 me to envision what more could have 200 00:09:39,680 --> 00:09:36,480 happened then then has happened we 201 00:09:41,840 --> 00:09:39,690 wanted to fly low we flew low and we 202 00:09:44,240 --> 00:09:41,850 learned enough by flying low that it was 203 00:09:47,630 --> 00:09:44,250 possible to challenge the team to fly 204 00:09:49,090 --> 00:09:47,640 lower and and then lower yet let's go 205 00:09:51,050 --> 00:09:49,100 over some of the scientific 206 00:09:55,340 --> 00:09:51,060 accomplishments of its prime mission 207 00:09:57,860 --> 00:09:55,350 what did you discover ok so the analysis 208 00:10:00,260 --> 00:09:57,870 of gravity is very complicated and and 209 00:10:04,310 --> 00:10:00,270 so the initial results have only just 210 00:10:08,540 --> 00:10:04,320 come out but but the first results have 211 00:10:10,910 --> 00:10:08,550 shown that the moon was heavily 212 00:10:12,890 --> 00:10:10,920 fractured in the exterior well now we 213 00:10:14,000 --> 00:10:12,900 knew from the bombardment in the early 214 00:10:16,520 --> 00:10:14,010 solar system that 215 00:10:17,810 --> 00:10:16,530 fracturing of the outside of planets has 216 00:10:19,940 --> 00:10:17,820 occurred this is something that we call 217 00:10:21,290 --> 00:10:19,950 the planetary regolith but what we've 218 00:10:24,430 --> 00:10:21,300 been able to show is that this 219 00:10:27,680 --> 00:10:24,440 fracturing is much more intensive and 220 00:10:30,770 --> 00:10:27,690 extends much deeper into the crust than 221 00:10:32,840 --> 00:10:30,780 we had ever thought of before and and in 222 00:10:33,950 --> 00:10:32,850 fact that this kind of fracturing must 223 00:10:37,100 --> 00:10:33,960 have occurred on other terrestrial 224 00:10:40,940 --> 00:10:37,110 planets as well so because fractures 225 00:10:42,770 --> 00:10:40,950 provide a pathway for volatile this is 226 00:10:45,350 --> 00:10:42,780 going to tell us things about the 227 00:10:47,180 --> 00:10:45,360 formation of early atmospheres as well 228 00:10:49,240 --> 00:10:47,190 as the possible transport of volatiles 229 00:10:53,510 --> 00:10:49,250 between the surface and the interior 230 00:10:57,350 --> 00:10:53,520 we've also learned things about the 231 00:11:00,650 --> 00:10:57,360 early expansion of the moon by the 232 00:11:03,050 --> 00:11:00,660 determination of large dikes that have 233 00:11:05,600 --> 00:11:03,060 not been visible at the surface they 234 00:11:06,620 --> 00:11:05,610 were predicted by models but any record 235 00:11:09,560 --> 00:11:06,630 that might have been at the surface 236 00:11:11,150 --> 00:11:09,570 would have been wiped out we've 237 00:11:13,340 --> 00:11:11,160 determined the thickness of the lunar 238 00:11:16,190 --> 00:11:13,350 crust finally we have crustal thickness 239 00:11:18,470 --> 00:11:16,200 model of the moon globally that matches 240 00:11:21,500 --> 00:11:18,480 the point measurements that have come 241 00:11:23,390 --> 00:11:21,510 from Apollo seismics and and this shows 242 00:11:25,430 --> 00:11:23,400 us that the moon's crust is actually 243 00:11:29,300 --> 00:11:25,440 much thinner than we thought before we 244 00:11:31,400 --> 00:11:29,310 have that show image of the animation of 245 00:11:33,350 --> 00:11:31,410 the gravity map and we can play that 246 00:11:36,410 --> 00:11:33,360 while I I talked to you a little bit 247 00:11:38,120 --> 00:11:36,420 more about this how are we going to use 248 00:11:40,520 --> 00:11:38,130 this information this is information 249 00:11:44,810 --> 00:11:40,530 that scientists have wanted for a long 250 00:11:49,150 --> 00:11:44,820 time well it's um yes I mean this will 251 00:11:51,920 --> 00:11:49,160 be used to study geophysics to get at 252 00:11:54,920 --> 00:11:51,930 the structure of the moon the early heat 253 00:11:58,100 --> 00:11:54,930 flow of the moon but but the state it 254 00:12:00,260 --> 00:11:58,110 will it will be a boon for geochemist 255 00:12:02,960 --> 00:12:00,270 petrology studying the composition of 256 00:12:07,430 --> 00:12:02,970 the moon which what's been very apparent 257 00:12:09,800 --> 00:12:07,440 so far is just what great interest this 258 00:12:12,140 --> 00:12:09,810 data is for people who study lunar 259 00:12:13,640 --> 00:12:12,150 samples so we continue to study the 260 00:12:16,640 --> 00:12:13,650 lunar samples we continue to learn 261 00:12:19,790 --> 00:12:16,650 things but what was what was actually 262 00:12:22,010 --> 00:12:19,800 very exciting was our density values for 263 00:12:24,470 --> 00:12:22,020 the moon and how the well those compared 264 00:12:26,000 --> 00:12:24,480 with the point values from lunar samples 265 00:12:27,040 --> 00:12:26,010 that were collected from the moon 40 266 00:12:28,509 --> 00:12:27,050 years ago and 267 00:12:30,460 --> 00:12:28,519 speaking about learning from this 268 00:12:33,570 --> 00:12:30,470 information and learning from the moon 269 00:12:37,389 --> 00:12:33,580 one of the aspects of this mission is 270 00:12:40,509 --> 00:12:37,399 outreach to middle school students to 271 00:12:42,250 --> 00:12:40,519 learn about science and to be excited 272 00:12:44,829 --> 00:12:42,260 about science talk to me a little bit 273 00:12:47,920 --> 00:12:44,839 about moon camp and we have footage from 274 00:12:51,190 --> 00:12:47,930 the moon cam cameras of a fly over the 275 00:12:53,410 --> 00:12:51,200 surface well we are extremely proud of 276 00:12:57,069 --> 00:12:53,420 the moon cam investigation which is the 277 00:13:00,310 --> 00:12:57,079 first time and imaging imaging device 278 00:13:03,280 --> 00:13:00,320 has actually flown on a NASA spacecraft 279 00:13:05,889 --> 00:13:03,290 and been totally to get dedicated to 280 00:13:10,110 --> 00:13:05,899 education and outreach so the moon camp 281 00:13:13,780 --> 00:13:10,120 program enlisted over 200,000 students 282 00:13:18,420 --> 00:13:13,790 over 3,600 classrooms from the US and 283 00:13:22,449 --> 00:13:18,430 actually 63 countries and students have 284 00:13:24,550 --> 00:13:22,459 targeted over a hundred thousand images 285 00:13:28,030 --> 00:13:24,560 of the lunar surface which are all 286 00:13:31,120 --> 00:13:28,040 posted online we've extended the funding 287 00:13:34,870 --> 00:13:31,130 of the moon cam investigation in order 288 00:13:37,540 --> 00:13:34,880 to develop more exercises to study the 289 00:13:39,790 --> 00:13:37,550 images so that these images can be used 290 00:13:43,300 --> 00:13:39,800 as a resource for years to come for 291 00:13:44,949 --> 00:13:43,310 teachers who are interested in teaching 292 00:13:46,420 --> 00:13:44,959 students about the moon something that 293 00:13:48,790 --> 00:13:46,430 goes beyond just learning what the 294 00:13:50,560 --> 00:13:48,800 phases of the war so it'll be archived 295 00:13:53,620 --> 00:13:50,570 there for future students to learn 296 00:13:55,690 --> 00:13:53,630 exactly alright Bria I know you're 297 00:13:57,940 --> 00:13:55,700 standing by thank you so much and we'll 298 00:13:59,860 --> 00:13:57,950 talk to you a little bit later meantime 299 00:14:02,860 --> 00:13:59,870 let's talk about some of the first 300 00:14:05,650 --> 00:14:02,870 students who ever used moon cam they 301 00:14:09,250 --> 00:14:05,660 were fourth graders from a school Emily 302 00:14:12,460 --> 00:14:09,260 Dickinson Elementary in Bozeman Montana 303 00:14:15,550 --> 00:14:12,470 they were the kids that named the two 304 00:14:18,550 --> 00:14:15,560 spacecraft they named them ebb and flow 305 00:14:20,500 --> 00:14:18,560 and remembering back that day when they 306 00:14:22,630 --> 00:14:20,510 made the announcement is one of the 307 00:14:29,470 --> 00:14:22,640 highlights of this mission take a look 308 00:14:32,350 --> 00:14:29,480 back we gave these two spacecraft names 309 00:14:36,010 --> 00:14:32,360 of a and B so we asked the youth of 310 00:14:37,720 --> 00:14:36,020 America to assist us in in getting 311 00:14:40,830 --> 00:14:37,730 slightly better names and we held a 312 00:14:43,830 --> 00:14:40,840 nationwide contest over 11 313 00:14:46,830 --> 00:14:43,840 thousand students wrote essays there was 314 00:14:49,560 --> 00:14:46,840 a very competitive competition Grail is 315 00:14:51,330 --> 00:14:49,570 the first spacecraft mission to carry 316 00:14:53,700 --> 00:14:51,340 instruments that are entirely dedicated 317 00:14:56,910 --> 00:14:53,710 to education cameras that will be 318 00:14:58,740 --> 00:14:56,920 operated by students and it's my 319 00:15:02,850 --> 00:14:58,750 pleasure to introduce fourth grade 320 00:15:04,830 --> 00:15:02,860 teachers Nina tomorrow class at Emily 321 00:15:08,190 --> 00:15:04,840 Dickinson school submitted the winning 322 00:15:40,190 --> 00:15:08,200 entry Nina congratulations we're so 323 00:15:44,490 --> 00:15:40,200 thrilled that our names were chosen and 324 00:15:47,280 --> 00:15:44,500 that was one of the very special moments 325 00:15:50,250 --> 00:15:47,290 of this mission with me right now is dr. 326 00:15:52,670 --> 00:15:50,260 Charles elachi he is the director of the 327 00:15:56,010 --> 00:15:52,680 jet propulsion laboratory JPL manages 328 00:15:57,660 --> 00:15:56,020 the gray mission and tell me a little 329 00:15:59,970 --> 00:15:57,670 bit about your feelings about the 330 00:16:01,860 --> 00:15:59,980 success of this mission yeah me first no 331 00:16:04,620 --> 00:16:01,870 question we have mixed feeling about it 332 00:16:06,210 --> 00:16:04,630 in the sense of when you work these 333 00:16:08,100 --> 00:16:06,220 missions for so many years they become 334 00:16:11,100 --> 00:16:08,110 like part of the family so people do 335 00:16:13,050 --> 00:16:11,110 feel you know the angst but you know the 336 00:16:14,640 --> 00:16:13,060 end of the mission on the other hand it 337 00:16:17,490 --> 00:16:14,650 is a celebration because this mission 338 00:16:20,130 --> 00:16:17,500 have accomplished tremendous science it 339 00:16:21,840 --> 00:16:20,140 was superbly well managed it thanks for 340 00:16:24,660 --> 00:16:21,850 on schedule and well within the budget 341 00:16:26,280 --> 00:16:24,670 that was committed to NASA it's 342 00:16:28,770 --> 00:16:26,290 improving our knowledge of the moon 343 00:16:30,450 --> 00:16:28,780 literally by orders of magnitude and 344 00:16:32,760 --> 00:16:30,460 it's so clearly it was one of the 345 00:16:35,310 --> 00:16:32,770 greatest success that we have in space 346 00:16:37,800 --> 00:16:35,320 exploration and even from an engineering 347 00:16:40,110 --> 00:16:37,810 standpoint we're learning from this 348 00:16:42,180 --> 00:16:40,120 the burn to depletion will give us 349 00:16:44,940 --> 00:16:42,190 information that will help us for future 350 00:16:46,740 --> 00:16:44,950 mission absolutely and and I mean the 351 00:16:49,710 --> 00:16:46,750 team is using every possibility and 352 00:16:52,350 --> 00:16:49,720 every opportunity to improve our future 353 00:16:54,570 --> 00:16:52,360 prediction for future missions and the 354 00:16:57,870 --> 00:16:54,580 knowledge of them of the gravitational 355 00:16:59,670 --> 00:16:57,880 field is now so accurate that it will 356 00:17:02,730 --> 00:16:59,680 enable as in the future which lie 357 00:17:05,010 --> 00:17:02,740 mission be it NASA mission or possibly 358 00:17:06,510 --> 00:17:05,020 commercial missions in the future we 359 00:17:08,790 --> 00:17:06,520 will be able to navigate much more 360 00:17:10,829 --> 00:17:08,800 accurately about where do we land in how 361 00:17:13,770 --> 00:17:10,839 we fly over the moon that would also 362 00:17:16,860 --> 00:17:13,780 apply to manned missions as well having 363 00:17:18,870 --> 00:17:16,870 such a accurate map this way yeah 364 00:17:20,850 --> 00:17:18,880 absolutely i mean it's the same thing as 365 00:17:23,040 --> 00:17:20,860 here on earth that we have the GPS 366 00:17:25,410 --> 00:17:23,050 Network which allow us you know to land 367 00:17:27,390 --> 00:17:25,420 airplanes very accurately this one 368 00:17:29,490 --> 00:17:27,400 enable us not because of GPS but because 369 00:17:31,620 --> 00:17:29,500 of the knowledge of the gravity field it 370 00:17:33,840 --> 00:17:31,630 will allow us to navigate both human and 371 00:17:36,000 --> 00:17:33,850 robotic mission to land basically do 372 00:17:37,680 --> 00:17:36,010 pinpoint you know landing on the morning 373 00:17:40,110 --> 00:17:37,690 and for future exploration that will be 374 00:17:42,360 --> 00:17:40,120 very important so with this success 375 00:17:44,940 --> 00:17:42,370 behind us what do we look to the future 376 00:17:46,770 --> 00:17:44,950 for me well the future also looks very 377 00:17:48,330 --> 00:17:46,780 good i mean nasa is very committed for 378 00:17:50,600 --> 00:17:48,340 in our countries committed to keep 379 00:17:54,750 --> 00:17:50,610 leadership role in planetary exploration 380 00:17:57,390 --> 00:17:54,760 being the moon or the planets as you 381 00:17:59,280 --> 00:17:57,400 know after the landing of curiosity 382 00:18:01,290 --> 00:17:59,290 which attracted the 50 million people 383 00:18:03,600 --> 00:18:01,300 were watching that landing and NASA 384 00:18:06,060 --> 00:18:03,610 decided to lay out a new plan for Mars 385 00:18:07,800 --> 00:18:06,070 so we have the mission insight which 386 00:18:10,620 --> 00:18:07,810 will be landing in twenty sixteen to 387 00:18:12,300 --> 00:18:10,630 look at marsquakes and learn more about 388 00:18:15,270 --> 00:18:12,310 the internal structure of the moon and 389 00:18:17,940 --> 00:18:15,280 recently nasa announced a 2020 you know 390 00:18:20,070 --> 00:18:17,950 Mars rover mission that will take us the 391 00:18:21,870 --> 00:18:20,080 next step in exploration of Mars we have 392 00:18:23,910 --> 00:18:21,880 the Juno mission which is heading toward 393 00:18:25,830 --> 00:18:23,920 Jupiter which will give us insight about 394 00:18:28,230 --> 00:18:25,840 the internal structure you know of 395 00:18:30,750 --> 00:18:28,240 Jupiter and and there is a whole series 396 00:18:33,060 --> 00:18:30,760 of mission that our country will play 397 00:18:35,310 --> 00:18:33,070 the leadership lower in in planetary 398 00:18:37,530 --> 00:18:35,320 exploration so we're all excited you 399 00:18:40,020 --> 00:18:37,540 know about that combination of missions 400 00:18:42,720 --> 00:18:40,030 well dr. Elijah never a boring moment 401 00:18:45,820 --> 00:18:42,730 here at Jamie all right thank you for 402 00:18:48,279 --> 00:18:45,830 joining us well JPL is not 403 00:18:50,470 --> 00:18:48,289 alone in the operation of the Grail 404 00:18:53,649 --> 00:18:50,480 mission we are also partners with 405 00:18:56,470 --> 00:18:53,659 Lockheed Martin space systems in Denver 406 00:18:58,779 --> 00:18:56,480 Colorado and we spoke to some of the the 407 00:19:01,509 --> 00:18:58,789 team over there and like the folks here 408 00:19:10,090 --> 00:19:01,519 they're looking at this moment with 409 00:19:12,549 --> 00:19:10,100 mixed emotions operating the the two 410 00:19:14,919 --> 00:19:12,559 spacecraft here in the mission support 411 00:19:16,779 --> 00:19:14,929 air Lockheed Martin has been has been 412 00:19:18,659 --> 00:19:16,789 very exciting during the extended 413 00:19:21,490 --> 00:19:18,669 mission we've been doing maneuvers 414 00:19:23,590 --> 00:19:21,500 extraordinarily frequently a few 415 00:19:26,019 --> 00:19:23,600 maneuvers a week we're flying through 416 00:19:28,720 --> 00:19:26,029 space craft at the same time it adds 417 00:19:30,549 --> 00:19:28,730 some more complexity to attitude control 418 00:19:32,080 --> 00:19:30,559 the Grail extended mission well has been 419 00:19:33,850 --> 00:19:32,090 slightly different from the primary 420 00:19:35,769 --> 00:19:33,860 mission that it is a little bit more 421 00:19:39,610 --> 00:19:35,779 sporty we knew that going into it what 422 00:19:43,480 --> 00:19:39,620 we've been doing is flying over the moon 423 00:19:45,850 --> 00:19:43,490 surface solo and as we fly we've been 424 00:19:48,100 --> 00:19:45,860 going down into basins and then we have 425 00:19:51,100 --> 00:19:48,110 to do maneuvers to pop us up over the 426 00:19:54,519 --> 00:19:51,110 bridges that follow those bases and so 427 00:19:56,019 --> 00:19:54,529 it's been constantly these three 428 00:19:57,700 --> 00:19:56,029 maneuvers a week to keep us from 429 00:20:00,519 --> 00:19:57,710 crashing into the moon the two 430 00:20:02,470 --> 00:20:00,529 spacecraft have behaved remarkably so 431 00:20:05,200 --> 00:20:02,480 it's actually made our jobs a lot easier 432 00:20:06,430 --> 00:20:05,210 not having to constantly deal with 433 00:20:08,889 --> 00:20:06,440 anomalies 434 00:20:11,680 --> 00:20:08,899 investigate problems we've been flying 435 00:20:14,529 --> 00:20:11,690 low over the moon for this extended 436 00:20:17,440 --> 00:20:14,539 mission in order to get high precision 437 00:20:19,419 --> 00:20:17,450 gravity data and it's the most high 438 00:20:22,810 --> 00:20:19,429 precision gravity data that's been 439 00:20:24,310 --> 00:20:22,820 measured at the moon to date ending the 440 00:20:25,299 --> 00:20:24,320 grill mission coming to an end it's 441 00:20:28,450 --> 00:20:25,309 there's definitely a lot of mixed 442 00:20:30,669 --> 00:20:28,460 feelings personally I am excited but 443 00:20:33,039 --> 00:20:30,679 it's also kind of sad because it's it's 444 00:20:37,320 --> 00:20:33,049 been a huge part of my life and the 445 00:20:40,450 --> 00:20:37,330 entire team's life we've gotten to fly a 446 00:20:42,789 --> 00:20:40,460 complex mission and do things that no 447 00:20:45,369 --> 00:20:42,799 one has done before with this kind of 448 00:20:49,029 --> 00:20:45,379 spacecraft doing all these maneuvers in 449 00:20:51,610 --> 00:20:49,039 a week just avoiding the train by flying 450 00:20:53,590 --> 00:20:51,620 down its basins and up over ridges it's 451 00:20:57,760 --> 00:20:53,600 been a it's been an honor and it's been 452 00:21:03,410 --> 00:21:00,140 part of the team here that works 453 00:21:05,090 --> 00:21:03,420 hand-in-hand and works a lot with the 454 00:21:08,210 --> 00:21:05,100 team at Lockheed Martin is our 455 00:21:11,150 --> 00:21:08,220 navigation team and with me right now is 456 00:21:14,240 --> 00:21:11,160 Sarah hatch she's a trajectory analyst 457 00:21:16,160 --> 00:21:14,250 and you're a member of the navigation 458 00:21:18,230 --> 00:21:16,170 team which is right down the hall from 459 00:21:20,540 --> 00:21:18,240 us here yeah we've done the whole 460 00:21:22,640 --> 00:21:20,550 they're watching closely why don't you 461 00:21:24,740 --> 00:21:22,650 tell us exactly what the NAP team does 462 00:21:26,660 --> 00:21:24,750 well there's about 20 people on the 463 00:21:29,000 --> 00:21:26,670 Grail nav team over in the room down the 464 00:21:30,920 --> 00:21:29,010 hall and we have several different 465 00:21:32,390 --> 00:21:30,930 functions as my job as the trajectory 466 00:21:34,640 --> 00:21:32,400 analyst is to figure out where the 467 00:21:36,320 --> 00:21:34,650 spacecraft needs to go to satisfy all of 468 00:21:38,750 --> 00:21:36,330 its science requirements and 469 00:21:41,270 --> 00:21:38,760 communication requirements so we plan 470 00:21:43,190 --> 00:21:41,280 the path the other analyst Mark Wallace 471 00:21:44,930 --> 00:21:43,200 and I have planned out these 78 472 00:21:48,410 --> 00:21:44,940 maneuvers that Grail has gone through 473 00:21:50,450 --> 00:21:48,420 and we plan the path the other part of 474 00:21:52,610 --> 00:21:50,460 that is the orbit determination they 475 00:21:54,440 --> 00:21:52,620 figure out the data that comes in figure 476 00:21:57,020 --> 00:21:54,450 out where we are along that path most 477 00:21:58,910 --> 00:21:57,030 likely we're not exactly on it so what 478 00:22:01,640 --> 00:21:58,920 we do then is have the maneuver design 479 00:22:02,930 --> 00:22:01,650 team design the maneuvers so the to 480 00:22:04,580 --> 00:22:02,940 judge people say this is what the 481 00:22:05,960 --> 00:22:04,590 maneuver should do but since we're not 482 00:22:08,090 --> 00:22:05,970 on that path the maneuver is going to be 483 00:22:09,680 --> 00:22:08,100 different so they design the maneuver 484 00:22:11,240 --> 00:22:09,690 pass that off to the folks at Lockheed 485 00:22:12,740 --> 00:22:11,250 Martin to implement it on the spacecraft 486 00:22:14,300 --> 00:22:12,750 the spacecraft points in the right 487 00:22:16,310 --> 00:22:14,310 direction burns for the right amount of 488 00:22:18,830 --> 00:22:16,320 time to get the the change velocity we 489 00:22:20,630 --> 00:22:18,840 need speaking of the burn we're looking 490 00:22:23,060 --> 00:22:20,640 at the Doppler here can you walk us 491 00:22:25,190 --> 00:22:23,070 through what's transpired since the 492 00:22:27,290 --> 00:22:25,200 burnin and how did the burn go the 493 00:22:29,300 --> 00:22:27,300 burghley great we actually burned a 494 00:22:30,770 --> 00:22:29,310 little longer than we expected so we had 495 00:22:32,780 --> 00:22:30,780 a little bit more fuel in the tanks than 496 00:22:34,130 --> 00:22:32,790 we thought we had which is good news and 497 00:22:35,780 --> 00:22:34,140 it will help the Lockheed Martin folks a 498 00:22:37,850 --> 00:22:35,790 lot in determining how much fuel is on 499 00:22:40,910 --> 00:22:37,860 the next mission we burned for about 500 00:22:43,030 --> 00:22:40,920 four minutes on grill a ebb and just 501 00:22:46,130 --> 00:22:43,040 over five minutes on Grail be flow and 502 00:22:48,950 --> 00:22:46,140 as the Doppler came in we were kind of 503 00:22:52,010 --> 00:22:48,960 walking up that line there was a maximum 504 00:22:54,800 --> 00:22:52,020 possibility and way out their maximum 505 00:22:57,080 --> 00:22:54,810 possibility 55 meters per second grill a 506 00:22:59,690 --> 00:22:57,090 was just over 20 meters per second Grail 507 00:23:01,760 --> 00:22:59,700 be was just over 25 almost 26 meters per 508 00:23:04,370 --> 00:23:01,770 second so they went really really well 509 00:23:06,050 --> 00:23:04,380 the data is coming in and our team back 510 00:23:08,540 --> 00:23:06,060 in the other room is analyzing that data 511 00:23:10,420 --> 00:23:08,550 and getting updated estimates on where 512 00:23:13,610 --> 00:23:10,430 we're going to impact on 513 00:23:15,770 --> 00:23:13,620 crater ridge quickly we have one of the 514 00:23:18,650 --> 00:23:15,780 displays that the team has come up with 515 00:23:21,320 --> 00:23:18,660 walk us through as to what we're seeing 516 00:23:24,710 --> 00:23:21,330 we're seeing a blue line and a red line 517 00:23:28,130 --> 00:23:24,720 that indicates Evan flow and where 518 00:23:30,290 --> 00:23:28,140 they're targeted yes if there were to be 519 00:23:32,270 --> 00:23:30,300 no burnet depletion maneuver we would 520 00:23:35,060 --> 00:23:32,280 have ended up on that kind of red 521 00:23:36,680 --> 00:23:35,070 contour there more to the right because 522 00:23:38,540 --> 00:23:36,690 we did those maneuvers we move to the 523 00:23:41,480 --> 00:23:38,550 left and we also moved down on that 524 00:23:43,700 --> 00:23:41,490 crater wall so you can see there on the 525 00:23:45,650 --> 00:23:43,710 the a line is or the red line it's Grail 526 00:23:47,570 --> 00:23:45,660 a.m. and the blue line is grilled beef 527 00:23:49,850 --> 00:23:47,580 lo there approximately going to hit 528 00:23:52,040 --> 00:23:49,860 about three kilometers apart and there 529 00:23:54,140 --> 00:23:52,050 I'm about 32 seconds apart and impact 530 00:23:56,000 --> 00:23:54,150 time and the impact terms are very close 531 00:23:57,710 --> 00:23:56,010 to what we expected them to be because 532 00:24:00,320 --> 00:23:57,720 our Delta bees weren't too far off from 533 00:24:01,670 --> 00:24:00,330 what we expected and so that's what 534 00:24:04,970 --> 00:24:01,680 they're going to impact on the mountain 535 00:24:06,890 --> 00:24:04,980 and as the data comes in there'll be a 536 00:24:09,140 --> 00:24:06,900 little dot that moves along to kind of 537 00:24:10,700 --> 00:24:09,150 show where the spacecraft are on the 538 00:24:12,550 --> 00:24:10,710 bottom part it's kind of a cross section 539 00:24:15,110 --> 00:24:12,560 of that mountain and some downstream 540 00:24:18,260 --> 00:24:15,120 topography and you can see there's kind 541 00:24:21,980 --> 00:24:18,270 of a little ridge south of our impact 542 00:24:24,950 --> 00:24:21,990 location that we design these maneuvers 543 00:24:27,650 --> 00:24:24,960 not to impact there and so we skip over 544 00:24:29,780 --> 00:24:27,660 that mountain and then impact the crater 545 00:24:31,100 --> 00:24:29,790 rock wall so it looks like we're clear 546 00:24:33,350 --> 00:24:31,110 over the wrist yeah looks like we're 547 00:24:35,990 --> 00:24:33,360 pretty we're right on target yep alright 548 00:24:38,990 --> 00:24:36,000 Sarah thank you so much I don't know if 549 00:24:41,060 --> 00:24:39,000 you heard but we hurt the call just a 550 00:24:43,520 --> 00:24:41,070 little while ago that we are five 551 00:24:45,320 --> 00:24:43,530 minutes away from impact and because 552 00:24:49,880 --> 00:24:45,330 with that where you are going to head 553 00:24:53,060 --> 00:24:49,890 over here to Glenn havens and Glenn is 554 00:24:56,450 --> 00:24:53,070 the deputy mission manager who is going 555 00:24:58,430 --> 00:24:56,460 to walk us through and tell us exactly 556 00:25:00,410 --> 00:24:58,440 what's happening with this impact a 557 00:25:02,810 --> 00:25:00,420 play-by-play tell us what's happening so 558 00:25:04,550 --> 00:25:02,820 far well we just crossed about the 559 00:25:07,610 --> 00:25:04,560 5-minute mark it was just called out on 560 00:25:09,350 --> 00:25:07,620 the on on the net so all the teams now 561 00:25:12,170 --> 00:25:09,360 are basically watching the Doppler 562 00:25:14,210 --> 00:25:12,180 display so the Doppler is two-way data 563 00:25:17,120 --> 00:25:14,220 that we're getting from each orbiter are 564 00:25:19,310 --> 00:25:17,130 on stations that are tracking here in 565 00:25:21,470 --> 00:25:19,320 this case from Goldstone California are 566 00:25:22,940 --> 00:25:21,480 sending signals we get those back and it 567 00:25:23,450 --> 00:25:22,950 basically shows us that the spacecraft 568 00:25:26,029 --> 00:25:23,460 are 569 00:25:28,250 --> 00:25:26,039 live and access our heartbeat right now 570 00:25:31,159 --> 00:25:28,260 so we're watching these signals watching 571 00:25:33,500 --> 00:25:31,169 this Green Line get closer to the time 572 00:25:35,090 --> 00:25:33,510 we expect the impact when it reaches 573 00:25:36,200 --> 00:25:35,100 that we expect that signal to go away 574 00:25:38,180 --> 00:25:36,210 and that's going to mean that the 575 00:25:41,450 --> 00:25:38,190 orbiters have impacted on the moon and 576 00:25:43,700 --> 00:25:41,460 give us the time now we are what so 577 00:25:45,889 --> 00:25:43,710 we're about three minutes and 17 seconds 578 00:25:48,169 --> 00:25:45,899 for a gray LA and then grill bees just 579 00:25:50,899 --> 00:25:48,179 about a half a minute later so what are 580 00:25:52,399 --> 00:25:50,909 you looking most closely at then well I 581 00:25:54,230 --> 00:25:52,409 am watching this Doppler data and 582 00:25:56,600 --> 00:25:54,240 watching a track and you can see the 583 00:25:58,880 --> 00:25:56,610 lines have appeared here on this cross 584 00:26:00,409 --> 00:25:58,890 section of the topography so one of the 585 00:26:01,970 --> 00:26:00,419 things we're waiting for is just to see 586 00:26:04,700 --> 00:26:01,980 that signal pass over that Ridge that 587 00:26:07,130 --> 00:26:04,710 Sarah just told you about that'll show 588 00:26:09,049 --> 00:26:07,140 that we cleared it which we expect to so 589 00:26:10,789 --> 00:26:09,059 we're right on trajectory and now it's 590 00:26:13,549 --> 00:26:10,799 just waiting all right so we'll be 591 00:26:22,770 --> 00:26:13,559 standing by and as soon as you hear the 592 00:26:35,049 --> 00:26:25,120 so about two and a half minutes for Gore 593 00:26:37,930 --> 00:26:35,059 LA ok you stand up for now can you stand 594 00:26:39,430 --> 00:26:37,940 up for now and then put that chair 595 00:26:47,350 --> 00:26:39,440 there's like a whip around if I me to 596 00:26:57,760 --> 00:26:47,360 thank you that makes sense no because 597 00:27:26,340 --> 00:27:00,590 okay so two minutes for a gray la until 598 00:27:38,000 --> 00:27:28,470 we can see the signal here approaching 599 00:27:49,750 --> 00:27:40,190 just about a minute and 20 seconds for a 600 00:27:55,000 --> 00:27:52,450 Gorillaz passing over the rotations this 601 00:27:58,840 --> 00:27:55,010 is Grail a systems we are now at one 602 00:28:01,210 --> 00:27:58,850 minute to impact systems is just 603 00:28:04,570 --> 00:28:01,220 announced over the web that it's one 604 00:28:09,370 --> 00:28:04,580 minute nap confirms Gore LA has made it 605 00:28:16,120 --> 00:28:11,860 now we can see Grail B is passing over 606 00:28:17,620 --> 00:28:16,130 the same Ridge so kind of waiting for 607 00:28:26,210 --> 00:28:17,630 the call from nav that says they've made 608 00:28:32,040 --> 00:28:29,640 system through a pencil and that's just 609 00:28:34,110 --> 00:28:32,050 reported that we successfully navigated 610 00:28:39,180 --> 00:28:34,120 Grail be over the ridge and now we're on 611 00:28:41,670 --> 00:28:39,190 target for our impact grell I impacting 612

systems impact in 615 00:29:03,840 --> 00:29:01,120 three two one zero so systems has just 616 00:29:12,620 --> 00:29:03,850 made to call from Denver that we at the 617 00:29:24,480 --> 00:29:16,290 so the DSN station is just reported that 618 00:29:29,340 --> 00:29:24,490 we've lost signal for LA Oasis mm we 619 00:29:31,650 --> 00:29:29,350 have lost in all stations girlby systems 620 00:29:36,450 --> 00:29:31,660 we have passed the point of impact where 621 00:29:37,800 --> 00:29:36,460 Lee is past its impact time okay and 622 00:29:39,690 --> 00:29:37,810 then we just have the report from the 623 00:29:44,040 --> 00:29:39,700 DSM that we've lost signal for Grail be 624 00:29:45,960 --> 00:29:44,050 as well so both both spacecraft of an 625 00:30:06,800 --> 00:29:45,970

honor her contributions to 642 00:31:24,090 --> 00:31:21,760 education by naming the impact sites 643 00:31:27,960 --> 00:31:24,100 after her we know that nASA has plans 644 00:31:30,290 --> 00:31:27,970 for celebrating Sally's accomplishments 645 00:31:32,820 --> 00:31:30,300 in many different areas but her 646 00:31:35,820 --> 00:31:32,830 contributions to education in Grail and 647 00:31:38,310 --> 00:31:35,830 more generally to science technology and 648 00:31:40,440 --> 00:31:38,320 math education are very very special to 649 00:31:42,780 --> 00:31:40,450 our tune so we're

Apollo and and got 661 00:32:19,519 --> 00:32:16,570 excited about science and that way and 662 00:32:22,499 --> 00:32:19,529 then after becoming you know an 663 00:32:25,049 --> 00:32:22,509

00:32:33,370 curiosity science to middle school kids 667 00:32:37,049 --> 00:32:35,440 especially girls so it's really cool to 668 00:32:38,430 --> 00:32:37,059 know that when you look up now at the 669 00:32:40,680 --> 00:32:38,440 moon there's this little corner of the 670 00:32:43,200 --> 00:32:40,690 movements named after Sally and we hope 671 00:32:45,330 --> 00:32:43,210 that that kids will

00:33:00,370 and flow have removed a veil from the 678 00:33:06,060 --> 00:33:03,549 moon and and removing this veil will 679 00:33:08,129 --> 00:33:06,070 enable discoveries about the way the 680 00:33:11,460 --> 00:33:08,139 moon formed and evolved for many years 681 00:33:13,860 --> 00:33:11,470 to come well this has been so much part 682 00:33:15,690 --> 00:33:13,870 of your life and you'll

00:33:30,190 both spacecraft and from now on not only 689 00:33:35,399 --> 00:33:32,830 will we see the resting spot for the two 690 00:33:39,720 --> 00:33:35,409 spacecraft but we will also see it as a 691 00:33:42,450 --> 00:33:39,730 memorial to Sally Ride America's first 692 00:33:44,820 --> 00:33:42,460 woman in space so that wraps it up here
