1 00:00:16,910 --> 00:00:14,629 good morning and welcome to NASA Ames 2 00:00:19,670 --> 00:00:16,920 Research Center for the El cross-post 3 00:00:22,759 --> 00:00:19,680 impact news conference my name is Jonas 4 00:00:26,359 --> 00:00:22,769 Dino and public affairs officer for the 5 00:00:29,269 --> 00:00:26,369 El cross mission on our panel today we 6 00:00:32,269 --> 00:00:29,279 have Daniel Andrews el cross project 7 00:00:34,190 --> 00:00:32,279 manager anthony cola preet el cross 8 00:00:36,950 --> 00:00:34,200 principal investigator and project 9 00:00:39,020 --> 00:00:36,960 scientist Jennifer heldmann coordinator 10 00:00:42,080 --> 00:00:39,030 for the el cross observation campaign 11 00:00:44,750 --> 00:00:42,090 and Michael Wargo chief lunar scientists 12 00:00:48,200 --> 00:00:44,760 for exploration systems at NASA 13 00:00:49,880 --> 00:00:48,210 headquarters after each has spoken we 14 00:00:53,420 --> 00:00:49,890 will be taking questions from the news 15 00:00:56,360 --> 00:00:53,430 media before we begin we have a 16 00:01:04,299 --> 00:00:56,370 statement from the are aimed center 17 00:01:12,440 --> 00:01:08,050 good morning I guess my summary is 18 00:01:15,350 --> 00:01:12,450 really cool this is an exciting and a 19 00:01:18,020 --> 00:01:15,360 historic day for NASA and for scientists 20 00:01:20,330 --> 00:01:18,030 around the world today we kicked up some 21 00:01:22,640 --> 00:01:20,340 moon dust and all indications are it's 22 00:01:26,600 --> 00:01:22,650 going to be a very interesting set of 23 00:01:28,730 --> 00:01:26,610 results but maybe even more important 24 00:01:31,340 --> 00:01:28,740 than the results are some of the other 25 00:01:33,800 --> 00:01:31,350 things that have been shown here el 26 00:01:37,700 --> 00:01:33,810 cross showed that low cost small 27 00:01:40,429 --> 00:01:37,710 innovative satellite missions are able 28 00:01:42,980 --> 00:01:40,439 to not only excite the scientific 29 00:01:45,139 --> 00:01:42,990 community and the public but also to 30 00:01:47,660 --> 00:01:45,149 gather some really neat science in 31 00:01:51,230 --> 00:01:47,670 addition this showed the value of 32 00:01:55,010 --> 00:01:51,240 teamwork and the teamwork went across 33 00:01:58,130 --> 00:01:55,020 NASA a number of NASA centers not just 34 00:02:00,830 --> 00:01:58,140 NASA Ames NASA Goddard answer Kennedy 35 00:02:03,109 --> 00:02:00,840 Space Center headquarters in folks 36 00:02:05,389 --> 00:02:03,119 remember of other centers universities 37 00:02:07,119 --> 00:02:05,399 particularly the groups that have been 38 00:02:10,639 --> 00:02:07,129 making ground-based observations 39 00:02:11,660 --> 00:02:10,649 corporate partnerships particularly our 40 00:02:14,240 --> 00:02:11,670 prime part 41 00:02:15,559 --> 00:02:14,250 Northrop Grumman and internationally 42 00:02:18,740 --> 00:02:15,569 we've got scientists around the world 43 00:02:21,530 --> 00:02:18,750 working on this so this is truly a 44 00:02:24,949 --> 00:02:21,540 historic day for NASA it expands and 45 00:02:27,170 --> 00:02:24,959 continues our exploration and eventual 46 00:02:29,059 --> 00:02:27,180 expansion into the solar system so 47 00:02:30,710 --> 00:02:29,069 without further ado I'd like to turn it 48 00:02:32,630 --> 00:02:30,720 over to those that made it happen and by 49 00:02:40,400 --> 00:02:32,640 the way on behalf of NASA thank you 50 00:02:42,140 --> 00:02:40,410 thank you sir and I know everyone wants 51 00:02:44,540 --> 00:02:42,150 to hear from the team so with that I 52 00:02:47,479 --> 00:02:44,550 will hand it off today Thank You Jonas 53 00:02:49,990 --> 00:02:47,489 well good morning I think it's morning 54 00:02:52,850 --> 00:02:50,000 the team has been working very hard 55 00:02:55,100 --> 00:02:52,860 especially with this last push pretty 56 00:02:58,940 --> 00:02:55,110 continuously one of the one of the 57 00:03:02,870 --> 00:02:58,950 benefits of such a small team multiple 58 00:03:06,080 --> 00:03:02,880 hats for long hours the L cross mission 59 00:03:08,840 --> 00:03:06,090 has been just a great experience I'm 60 00:03:10,900 --> 00:03:08,850 very proud of this team who's partially 61 00:03:13,460 --> 00:03:10,910 represented up here but there's a whole 62 00:03:17,479 --> 00:03:13,470 much larger group of people who have 63 00:03:20,300 --> 00:03:17,489 done amazing work and given incredibly 64 00:03:24,890 --> 00:03:20,310 frankly personally and professionally to 65 00:03:27,099 --> 00:03:24,900 see this great mission through the I'm 66 00:03:29,360 --> 00:03:27,109 happy to report that the spacecraft 67 00:03:31,490 --> 00:03:29,370 performed beautifully throughout the 68 00:03:34,610 --> 00:03:31,500 mission the operations team drove it 69 00:03:38,930 --> 00:03:34,620 well and you here today to hear about 70 00:03:40,640 --> 00:03:38,940 some of our initial results I caution 71 00:03:42,860 --> 00:03:40,650 people that we've been saying for some 72 00:03:45,199 --> 00:03:42,870 time now it takes a while to comb 73 00:03:50,380 --> 00:03:45,209 through the data and make sure that we 74 00:03:52,220 --> 00:03:50,390 are reporting accurate and correct data 75 00:03:55,180 --> 00:03:52,230 but we did want to give you a little 76 00:03:58,039 --> 00:03:55,190 field before the the morning was out on 77 00:03:59,240 --> 00:03:58,049 how things went some of the stuff that 78 00:04:01,849 --> 00:03:59,250 we saw and you're going to see some 79 00:04:05,240 --> 00:04:01,859 interesting imagery and data from the 80 00:04:09,020 --> 00:04:05,250 team today and so with that I'll turn it 81 00:04:10,220 --> 00:04:09,030 over to Tony thank you Dan and yes the 82 00:04:12,140 --> 00:04:10,230 first thing that I've learned is how 83 00:04:15,289 --> 00:04:12,150 much fun it is to get ready for a press 84 00:04:19,090 --> 00:04:15,299 conference in and two hours after being 85 00:04:21,840 --> 00:04:19,100 up for 36 hours watching this this ride 86 00:04:26,890 --> 00:04:21,850 listen learn make that one down um 87 00:04:29,730 --> 00:04:26,900 thanks but yeah it was everything really 88 00:04:32,910 --> 00:04:29,740 worked out well the spacecraft clue 89 00:04:34,960 --> 00:04:32,920 perfectly the instruments performed 90 00:04:38,050 --> 00:04:34,970 honestly better than expected in some 91 00:04:39,430 --> 00:04:38,060 cases we got interesting results and I'm 92 00:04:41,500 --> 00:04:39,440 going to talk to you a little bit about 93 00:04:44,230 --> 00:04:41,510 those initially but again they're just 94 00:04:45,940 --> 00:04:44,240 initial results it took us most of time 95 00:04:48,400 --> 00:04:45,950 just to get the data get it calibrated 96 00:04:50,620 --> 00:04:48,410 off one thumb drive on to another 97 00:04:51,580 --> 00:04:50,630 computer and start processing it so what 98 00:04:54,100 --> 00:04:51,590 you're really going to see is just a 99 00:04:55,570 --> 00:04:54,110 first glimpse and as we get the teams 100 00:04:58,900 --> 00:04:55,580 together and get all the other 101 00:05:02,050 --> 00:04:58,910 observations in you know you'll hear 102 00:05:04,390 --> 00:05:02,060 more and more as the days go on but I 103 00:05:06,720 --> 00:05:04,400 can certainly report there was an impact 104 00:05:09,280 --> 00:05:06,730 we saw the impact we saw the crater and 105 00:05:11,910 --> 00:05:09,290 we got good measurement spectroscopic 106 00:05:15,550 --> 00:05:11,920 measurements which is what we needed of 107 00:05:17,350 --> 00:05:15,560 the the impact event so we have the data 108 00:05:19,090 --> 00:05:17,360 we need to actually address the 109 00:05:20,590 --> 00:05:19,100 questions we sent out to address and 110 00:05:22,060 --> 00:05:20,600 that's the fundamental bottom line 111 00:05:23,590 --> 00:05:22,070 that's what I out point you to take away 112 00:05:25,990 --> 00:05:23,600 today is I'm not going to say anything 113 00:05:27,640 --> 00:05:26,000 about water or no water but we got the 114 00:05:30,880 --> 00:05:27,650 measurements we need to address the 115 00:05:34,060 --> 00:05:30,890 questions so rather me talk more we can 116 00:05:35,530 --> 00:05:34,070 go to some of the images first up so if 117 00:05:38,190 --> 00:05:35,540 we go to the first power point 118 00:05:40,330 --> 00:05:38,200 presentation that I have in here 119 00:05:42,490 --> 00:05:40,340 actually there's a movie if we can play 120 00:05:43,660 --> 00:05:42,500 that movie fir SE VI now we'll start 121 00:05:46,300 --> 00:05:43,670 here and then we'll do the movie this is 122 00:05:47,770 --> 00:05:46,310 fine so we have a variety of cameras as 123 00:05:50,100 --> 00:05:47,780 you all know the visible camera really 124 00:05:52,900 --> 00:05:50,110 is this context camera and it was really 125 00:05:55,300 --> 00:05:52,910 fantastic to actually see this visible 126 00:05:57,130 --> 00:05:55,310 camera in our target site and compare it 127 00:05:59,410 --> 00:05:57,140 to our target charts and go yep that's 128 00:06:01,140 --> 00:05:59,420 where we're going perfect what you see 129 00:06:05,380 --> 00:06:01,150 in the center here is the cabayos crater 130 00:06:08,410 --> 00:06:05,390 at that we're headed out toward the next 131 00:06:11,190 --> 00:06:08,420 camera image is our near infrared camera 132 00:06:13,750 --> 00:06:11,200 and this is a camera that was used for 133 00:06:17,230 --> 00:06:13,760 flash detection and crater detection 134 00:06:20,350 --> 00:06:17,240 ultimately as as well as looking for 135 00:06:22,360 --> 00:06:20,360 ejecta and then the next slide shows our 136 00:06:23,980 --> 00:06:22,370 thermal camera and these thermal 137 00:06:26,350 --> 00:06:23,990 comments have always been kind of a a 138 00:06:28,239 --> 00:06:26,360 sweetheart of minded performed very well 139 00:06:30,489 --> 00:06:28,249 along with the near infrared cameras 140 00:06:33,249 --> 00:06:30,499 and so it measures temperature this is a 141 00:06:37,299 --> 00:06:33,259 grayscale but bright regions are hot 142 00:06:38,829 --> 00:06:37,309 cold regions dark regions are cold so 143 00:06:40,359 --> 00:06:38,839 these are I'm going to talk a little bit 144 00:06:42,699 --> 00:06:40,369 more about each of these three cameras 145 00:06:44,469 --> 00:06:42,709 and these are some views and about this 146 00:06:46,779 --> 00:06:44,479 the same altitude of the target site as 147 00:06:48,039 --> 00:06:46,789 we flew in we're probably about seven 148 00:06:50,699 --> 00:06:48,049 hundred or so kilometers above the 149 00:06:54,519 --> 00:06:50,709 surface at this point the next slide 150 00:06:59,379 --> 00:06:54,529 shows essentially our view from the 151 00:07:02,199 --> 00:06:59,389 inferred camera at impact and we're 152 00:07:05,139 --> 00:07:02,209 impacting to the end of the shadowed 153 00:07:08,109 --> 00:07:05,149 region to the to the left there also 154 00:07:09,969 --> 00:07:08,119 good news is that the shadows rep that 155 00:07:12,069 --> 00:07:09,979 we can really only just have modeled up 156 00:07:14,139 --> 00:07:12,079 to this point really look like the model 157 00:07:16,629 --> 00:07:14,149 so the topography that seems very 158 00:07:20,399 --> 00:07:16,639 accurate that we've gotten from the 159 00:07:23,559 --> 00:07:20,409 previous missions next slide shows the 160 00:07:24,999 --> 00:07:23,569 mid-infrared flash detection and it's 161 00:07:28,419 --> 00:07:25,009 kind of hard to see in this presentation 162 00:07:32,019 --> 00:07:28,429 apologize the the top I've got three in 163 00:07:34,299 --> 00:07:32,029 sets here the the larger picture shows 164 00:07:35,799 --> 00:07:34,309 the crater and then the lower left shows 165 00:07:38,259 --> 00:07:35,809 a zoom in and you see that little white 166 00:07:40,839 --> 00:07:38,269 speck there that is the impact flash 167 00:07:42,429 --> 00:07:40,849 from 600 kilometers away seen thermally 168 00:07:44,379 --> 00:07:42,439 so what we're seeing there is the 169 00:07:46,029 --> 00:07:44,389 temperature of that impact flash so we 170 00:07:48,729 --> 00:07:46,039 can actually go back and measure how hot 171 00:07:50,649 --> 00:07:48,739 it got and watch its evolution you see 172 00:07:53,079 --> 00:07:50,659 the flash over a few frames and the 173 00:07:55,179 --> 00:07:53,089 lower right is a zoom in there you see 174 00:07:57,459 --> 00:07:55,189 that the flash is actually several 175 00:08:01,209 --> 00:07:57,469 pixels across interesting don't know 176 00:08:03,100 --> 00:08:01,219 what that means could just be a smear 177 00:08:05,169 --> 00:08:03,110 it's a 30 frame per second camera we 178 00:08:07,089 --> 00:08:05,179 have to look interesting though so what 179 00:08:10,029 --> 00:08:07,099 was great as we've got nice definitive 180 00:08:14,259 --> 00:08:10,039 detection of the flash and we can follow 181 00:08:17,079 --> 00:08:14,269 up with that next presentation shows 182 00:08:19,329 --> 00:08:17,089 some spectrometer data so one of the 183 00:08:20,649 --> 00:08:19,339 things we did actually you know that 184 00:08:24,089 --> 00:08:20,659 you've probably heard me discuss is 185 00:08:26,589 --> 00:08:24,099 arranged the observations of this event 186 00:08:28,600 --> 00:08:26,599 around the event itself so there's 187 00:08:32,170 --> 00:08:28,610 impact flash so that's what you saw was 188 00:08:33,490 --> 00:08:32,180 impact flash we get the instruments in 189 00:08:36,100 --> 00:08:33,500 certain settings for that particular 190 00:08:38,169 --> 00:08:36,110 moment then there's a curtain evolution 191 00:08:41,409 --> 00:08:38,179 where ejecta comes up into sunlight 192 00:08:42,140 --> 00:08:41,419 volatiles come up vapors come up and we 193 00:08:43,370 --> 00:08:42,150 set the 194 00:08:45,410 --> 00:08:43,380 as for different exposures and 195 00:08:47,390 --> 00:08:45,420 integrations for that and then there's 196 00:08:50,030 --> 00:08:47,400 the Creator period when we are flying 197 00:08:51,860 --> 00:08:50,040 through the debris and vapor cloud 198 00:08:53,690 --> 00:08:51,870 whatever is left and we actually then 199 00:08:55,700 --> 00:08:53,700 try to image the Creator we made and 200 00:08:58,820 --> 00:08:55,710 learn about the vapor cloud we were 201 00:09:01,220 --> 00:08:58,830 flying through this was as it turns out 202 00:09:04,720 --> 00:09:01,230 a very smart thing to do because what it 203 00:09:07,640 --> 00:09:04,730 made us impacting into the moon is a 204 00:09:09,710 --> 00:09:07,650 unpredictable business at best but what 205 00:09:11,510 --> 00:09:09,720 we did was we actually are able to 206 00:09:13,040 --> 00:09:11,520 garner different information from each 207 00:09:15,830 --> 00:09:13,050 of those periods in our data set and 208 00:09:17,630 --> 00:09:15,840 that's what I'm excited about is each of 209 00:09:19,790 --> 00:09:17,640 those periods flash we you saw the 210 00:09:23,330 --> 00:09:19,800 thermal flash we actually as you'll see 211 00:09:25,820 --> 00:09:23,340 in a second have very good ultraviolet 212 00:09:28,490 --> 00:09:25,830 visible spectroscopy of the flash that's 213 00:09:29,870 --> 00:09:28,500 really exciting that was totally 214 00:09:31,910 --> 00:09:29,880 independent of everything else so that 215 00:09:33,770 --> 00:09:31,920 by itself may constitute enough to 216 00:09:35,600 --> 00:09:33,780 answer some fundamental questions and 217 00:09:37,580 --> 00:09:35,610 then we had the ejecta curtain we 218 00:09:39,770 --> 00:09:37,590 watched how that evolved in and looked 219 00:09:41,450 --> 00:09:39,780 for that and then the crater itself and 220 00:09:43,070 --> 00:09:41,460 so we as you'll see in a minute we 221 00:09:45,020 --> 00:09:43,080 actually saw a crater we measured its 222 00:09:47,110 --> 00:09:45,030 temperature and we're going to look at 223 00:09:50,210 --> 00:09:47,120 that even more closely coming forward 224 00:09:53,840 --> 00:09:50,220 going forward what you see here is back 225 00:09:57,530 --> 00:09:53,850 one back to human forward one they're 226 00:09:58,760 --> 00:09:57,540 good this is a visible spectrometer data 227 00:10:02,990 --> 00:09:58,770 so we have an ultraviolet visible 228 00:10:04,370 --> 00:10:03,000 spectrometer and it measures from the 229 00:10:06,920 --> 00:10:04,380 near El to violate all the way through 230 00:10:08,900 --> 00:10:06,930 red wavelengths and what you're shown 231 00:10:11,090 --> 00:10:08,910 here is a roll-up of all the energy in 232 00:10:12,410 --> 00:10:11,100 that spectrometer the total radiance so 233 00:10:14,300 --> 00:10:12,420 you're not seeing spectra here you just 234 00:10:16,520 --> 00:10:14,310 seen the toll signal and what you see 235 00:10:18,410 --> 00:10:16,530 here is that the strength of that signal 236 00:10:21,500 --> 00:10:18,420 as a function of time along the bottom 237 00:10:22,910 --> 00:10:21,510 so as we're flying in our field of view 238 00:10:24,620 --> 00:10:22,920 of that instrument what we're seeing is 239 00:10:26,180 --> 00:10:24,630 getting smaller and smaller and smaller 240 00:10:28,010 --> 00:10:26,190 and looking deeper and deeper into the 241 00:10:30,890 --> 00:10:28,020 shadow and that's exactly what you 242 00:10:33,650 --> 00:10:30,900 wanted to do and all the way to the end 243 00:10:35,030 --> 00:10:33,660 where you see that fall off way out 244 00:10:36,830 --> 00:10:35,040 towards in that's actually when the 245 00:10:41,230 --> 00:10:36,840 field of view of our spectrometer dips 246 00:10:44,420 --> 00:10:41,240 into total blackness and so on the far 247 00:10:46,400 --> 00:10:44,430 right of that image you see the little 248 00:10:48,170 --> 00:10:46,410 cliff and then you see a little blip 249 00:10:50,030 --> 00:10:48,180 right there and you'll talk more about 250 00:10:51,830 --> 00:10:50,040 that in a minute and then you see a 251 00:10:54,080 --> 00:10:51,840 larger bump the larger bump we believe 252 00:10:54,790 --> 00:10:54,090 is probably a processing artifact right 253 00:10:56,290 --> 00:10:54,800 now 254 00:10:59,050 --> 00:10:56,300 that we have to take out but the little 255 00:11:00,790 --> 00:10:59,060 blips very important that is actually 256 00:11:02,470 --> 00:11:00,800 the flash of the impact that the visible 257 00:11:04,150 --> 00:11:02,480 spectrometer picked up we're very 258 00:11:07,199 --> 00:11:04,160 excited about that because that's where 259 00:11:09,759 --> 00:11:07,209 you get thermalization of any vapors it 260 00:11:12,210 --> 00:11:09,769 hopefully will contain no H in it if 261 00:11:14,920 --> 00:11:12,220 there's water there we'll have to see 262 00:11:17,410 --> 00:11:14,930 next slide shows the near-infrared 263 00:11:21,329 --> 00:11:17,420 spectrometer so a similar pattern 264 00:11:23,590 --> 00:11:21,339 there's near-infrared spectrometer jose 265 00:11:24,880 --> 00:11:23,600 again a field of view that is getting 266 00:11:27,460 --> 00:11:24,890 smaller and smaller it's the same size 267 00:11:30,220 --> 00:11:27,470 and so it gets fainter and fainter as we 268 00:11:32,160 --> 00:11:30,230 dip into shadows that you see that 269 00:11:34,930 --> 00:11:32,170 little arrow and it's indicating it'll 270 00:11:36,190 --> 00:11:34,940 block that's missing the instrument 271 00:11:37,660 --> 00:11:36,200 actually goes into as I mentioned a 272 00:11:39,370 --> 00:11:37,670 different mode for flash and we're just 273 00:11:42,030 --> 00:11:39,380 not showing it here it actually measures 274 00:11:44,319 --> 00:11:42,040 the flash energy very quickly so we 275 00:11:46,630 --> 00:11:44,329 tempted to measure it there and then it 276 00:11:50,199 --> 00:11:46,640 comes out of that flash and looks at the 277 00:11:52,150 --> 00:11:50,209 ejecta curtain and the next slide I 278 00:11:55,990 --> 00:11:52,160 think shows these two kind of overlapped 279 00:11:57,880 --> 00:11:56,000 with each other so what you see is the 280 00:12:01,150 --> 00:11:57,890 black curve again is this an ultra light 281 00:12:04,780 --> 00:12:01,160 visible spectrometer and you see the the 282 00:12:07,120 --> 00:12:04,790 lope the first short blip is is the 283 00:12:09,220 --> 00:12:07,130 flash and its extensive and it doesn't 284 00:12:11,260 --> 00:12:09,230 go all the way down to zero hmm very 285 00:12:13,090 --> 00:12:11,270 interesting I'll just say that much 286 00:12:16,810 --> 00:12:13,100 about it it doesn't go to total 287 00:12:18,340 --> 00:12:16,820 blackness and like it did before and the 288 00:12:19,720 --> 00:12:18,350 near and Fred spectrometer has a trail 289 00:12:22,240 --> 00:12:19,730 off that's a little bit more shallow 290 00:12:25,060 --> 00:12:22,250 than expected so we're going to look at 291 00:12:27,870 --> 00:12:25,070 this but we're really excited that the 292 00:12:29,980 --> 00:12:27,880 spectrometers look to have captured the 293 00:12:31,870 --> 00:12:29,990 certainly the flash and possibly the 294 00:12:33,720 --> 00:12:31,880 ejecta cloud and given us assume that we 295 00:12:35,920 --> 00:12:33,730 need to answer the questions were after 296 00:12:38,199 --> 00:12:35,930 and then you can see at the end of that 297 00:12:40,389 --> 00:12:38,209 we go deeper and deeper into darkness 298 00:12:43,480 --> 00:12:40,399 and that's actually not next slides good 299 00:12:44,920 --> 00:12:43,490 because that's that's what we then start 300 00:12:46,689 --> 00:12:44,930 looking for the crater and this is 301 00:12:49,510 --> 00:12:46,699 really fun for me I was watching us go 302 00:12:51,100 --> 00:12:49,520 in and i gotta say i didn't i was blown 303 00:12:53,949 --> 00:12:51,110 away by how long this little spacecraft 304 00:12:55,389 --> 00:12:53,959 lasted i'm going to be it's going to be 305 00:12:57,670 --> 00:12:55,399 fun to see how close we were to the 306 00:13:01,900 --> 00:12:57,680 surface when it finally we lost contact 307 00:13:03,519 --> 00:13:01,910 with the poor poor guy but we saw it's 308 00:13:05,319 --> 00:13:03,529 hard to see again in these pictures so I 309 00:13:06,610 --> 00:13:05,329 blown it up that little those are two 310 00:13:09,670 --> 00:13:06,620 images 311 00:13:11,260 --> 00:13:09,680 like a third of a second apart from each 312 00:13:13,180 --> 00:13:11,270 other in top left net arrows pointing to 313 00:13:15,940 --> 00:13:13,190 a little blip maybe just a pixel or so 314 00:13:17,470 --> 00:13:15,950 but in the sock we've looked up and we 315 00:13:20,470 --> 00:13:17,480 saw that little blip appear and then 316 00:13:21,700 --> 00:13:20,480 also go skirting across the scene as we 317 00:13:23,920 --> 00:13:21,710 were coming in and trying to keep 318 00:13:25,480 --> 00:13:23,930 pointing at it that was a crater we made 319 00:13:27,880 --> 00:13:25,490 with the Centaur and that's what's blown 320 00:13:29,380 --> 00:13:27,890 up there it's at least a pixel across 321 00:13:31,810 --> 00:13:29,390 towards n it's a little bit more than a 322 00:13:34,120 --> 00:13:31,820 pixel and what's great about that as it 323 00:13:35,770 --> 00:13:34,130 confirms the actual size of the crater 324 00:13:37,390 --> 00:13:35,780 we were predicting I think it's pretty 325 00:13:39,520 --> 00:13:37,400 close to the crater besides we were 326 00:13:42,610 --> 00:13:39,530 thinking we have to go back and look but 327 00:13:44,380 --> 00:13:42,620 what's great is I was maybe not 328 00:13:46,840 --> 00:13:44,390 particularly optimistic we would see 329 00:13:48,640 --> 00:13:46,850 this crater like this but we actually 330 00:13:50,260 --> 00:13:48,650 got pretty good signal-to-noise and can 331 00:13:51,850 --> 00:13:50,270 actually go back and try to measure the 332 00:13:53,380 --> 00:13:51,860 temperature of this crater that's going 333 00:13:56,410 --> 00:13:53,390 to tell us something about the materials 334 00:13:58,390 --> 00:13:56,420 in there and what's great is diviner the 335 00:14:00,490 --> 00:13:58,400 instrument on LRO is making similar 336 00:14:03,550 --> 00:14:00,500 measurements with much bigger field of 337 00:14:05,830 --> 00:14:03,560 view and we can really corroborate those 338 00:14:07,780 --> 00:14:05,840 measurements and learn something more so 339 00:14:10,630 --> 00:14:07,790 that's a quick look at some of the 340 00:14:12,820 --> 00:14:10,640 camera data spectrometer data we weren't 341 00:14:13,870 --> 00:14:12,830 the only ones looking and so with that 342 00:14:17,020 --> 00:14:13,880 I'm going to actually turn it over to 343 00:14:18,700 --> 00:14:17,030 Jenn who's going to describe the broader 344 00:14:20,710 --> 00:14:18,710 observational campaign outside of 345 00:14:23,020 --> 00:14:20,720 they'll cross spacecraft great thanks 346 00:14:24,820 --> 00:14:23,030 Tony so while we pull up the slides here 347 00:14:26,680 --> 00:14:24,830 I'm I just want to echo piqued comments 348 00:14:28,720 --> 00:14:26,690 that this was so cool this is the 349 00:14:30,070 --> 00:14:28,730 greatest thing because uh this is what 350 00:14:31,810 --> 00:14:30,080 NASA does well and it's a really great 351 00:14:34,150 --> 00:14:31,820 day to be working here for the space 352 00:14:36,190 --> 00:14:34,160 agency and through through the 353 00:14:37,420 --> 00:14:36,200 observation campaign this is where a lot 354 00:14:39,640 --> 00:14:37,430 of the collaboration and cooperation 355 00:14:41,230 --> 00:14:39,650 came in we had a great number of teams 356 00:14:43,060 --> 00:14:41,240 that were observing and I'll show you a 357 00:14:44,470 --> 00:14:43,070 list of those as well we collected a 358 00:14:46,330 --> 00:14:44,480 tremendous amount of data through the 359 00:14:48,190 --> 00:14:46,340 observation campaign I should have 360 00:14:49,840 --> 00:14:48,200 mentioned that the philosophy behind the 361 00:14:52,300 --> 00:14:49,850 observing campaign was one of 362 00:14:53,680 --> 00:14:52,310 cooperation and collaboration so we 363 00:14:55,630 --> 00:14:53,690 brought this team together under the 364 00:14:57,370 --> 00:14:55,640 umbrella of observing el cross and so 365 00:14:58,720 --> 00:14:57,380 everyone's been working together we're 366 00:15:00,760 --> 00:14:58,730 looking at each other's data sharing 367 00:15:02,740 --> 00:15:00,770 data collaborating with the spacecraft 368 00:15:04,570 --> 00:15:02,750 and all the other space orbiting assets 369 00:15:05,620 --> 00:15:04,580 that have collected data as well because 370 00:15:07,660 --> 00:15:05,630 that's how we're going to learn the most 371 00:15:10,000 --> 00:15:07,670 from this from this unique experiment 372 00:15:11,500 --> 00:15:10,010 that we just did today so I want to give 373 00:15:14,560 --> 00:15:11,510 you just a flavor of some of the types 374 00:15:16,270 --> 00:15:14,570 of data that we collected we have images 375 00:15:18,490 --> 00:15:16,280 we have video we have graphs of squiggly 376 00:15:19,900 --> 00:15:18,500 lines that scientists love so we have a 377 00:15:21,220 --> 00:15:19,910 little bit of something forever 378 00:15:23,590 --> 00:15:21,230 one and I can only show you a snapshot 379 00:15:25,720 --> 00:15:23,600 here given time restrictions but there 380 00:15:26,890 --> 00:15:25,730 is a lot more that's available and a lot 381 00:15:28,870 --> 00:15:26,900 of this will be posted on the NASA 382 00:15:31,030 --> 00:15:28,880 website as well so you'll be able to go 383 00:15:32,410 --> 00:15:31,040 there just as a reminder of who is able 384 00:15:33,670 --> 00:15:32,420 to observe so we have ground-based 385 00:15:35,620 --> 00:15:33,680 observations and we also have 386 00:15:37,750 --> 00:15:35,630 space-based observations for the 387 00:15:39,550 --> 00:15:37,760 ground-based observations where the moon 388 00:15:40,750 --> 00:15:39,560 was up and where it was dark which is 389 00:15:43,900 --> 00:15:40,760 what you need for these types of 390 00:15:45,460 --> 00:15:43,910 measurements was from west of the 391 00:15:47,080 --> 00:15:45,470 Mississippi all the way out through say 392 00:15:49,120 --> 00:15:47,090 Hawaii and so that's where our 393 00:15:50,140 --> 00:15:49,130 observatories have been clustered and so 394 00:15:51,910 --> 00:15:50,150 that's where you'll see a lot of these 395 00:15:55,030 --> 00:15:51,920 observations coming from the south 396 00:15:56,710 --> 00:15:55,040 southwest us and then out to Hawaii we 397 00:15:58,060 --> 00:15:56,720 also had several space-based assets that 398 00:16:00,430 --> 00:15:58,070 were observing I'll talk about those as 399 00:16:02,350 --> 00:16:00,440 well so to give you a sense of some of 400 00:16:04,030 --> 00:16:02,360 the types of data that we have as I 401 00:16:06,270 --> 00:16:04,040 mentioned that the observation campaign 402 00:16:09,310 --> 00:16:06,280 everyone worked together on this and 403 00:16:10,390 --> 00:16:09,320 clear skies all around we really lucked 404 00:16:12,880 --> 00:16:10,400 out with the weather that was fantastic 405 00:16:15,100 --> 00:16:12,890 so all the folks that were signed up to 406 00:16:18,040 --> 00:16:15,110 observe had clear skies collected data I 407 00:16:20,230 --> 00:16:18,050 had no instrument issues or anything so 408 00:16:22,330 --> 00:16:20,240 we had all everything was nominal for 409 00:16:23,890 --> 00:16:22,340 the observatories so what we've seen 410 00:16:25,660 --> 00:16:23,900 here up on one of the maps this is a 411 00:16:27,490 --> 00:16:25,670 lunar South Pole map I want to give you 412 00:16:29,050 --> 00:16:27,500 a sense of where we actually went I want 413 00:16:31,270 --> 00:16:29,060 to get you familiar with this south 414 00:16:32,710 --> 00:16:31,280 polar region of the cabayos crater where 415 00:16:33,760 --> 00:16:32,720 we impacted so hopefully by the end of 416 00:16:35,350 --> 00:16:33,770 this you'll have a better appreciation 417 00:16:37,690 --> 00:16:35,360 for or we won't be able to pick it out 418 00:16:39,910 --> 00:16:37,700 yourself so this is an image from New 419 00:16:41,020 --> 00:16:39,920 Mexico State University and Marshall 420 00:16:42,610 --> 00:16:41,030 Space Flight Center another one of the 421 00:16:44,380 --> 00:16:42,620 NASA centers that we worked with this is 422 00:16:46,240 --> 00:16:44,390 the lunar South Pole map so you can see 423 00:16:48,070 --> 00:16:46,250 at the bottom the target crater kebaya 424 00:16:49,330 --> 00:16:48,080 siz actually labeled this is an image 425 00:16:51,640 --> 00:16:49,340 mosaic and this is part of the 426 00:16:52,750 --> 00:16:51,650 cooperation that happened before tonight 427 00:16:54,400 --> 00:16:52,760 we've been working on this for quite 428 00:16:56,620 --> 00:16:54,410 some time doing rehearsals and doing 429 00:16:58,690 --> 00:16:56,630 test runs to make sure that the pointing 430 00:17:01,090 --> 00:16:58,700 accuracy is correct it's not trivial to 431 00:17:02,800 --> 00:17:01,100 point these large telescopes at a very 432 00:17:04,210 --> 00:17:02,810 specific region on the moon it's 433 00:17:06,100 --> 00:17:04,220 difficult to observe the moon from the 434 00:17:08,320 --> 00:17:06,110 ground the moon's very bright so 435 00:17:09,610 --> 00:17:08,330 typically astronomers don't really like 436 00:17:11,530 --> 00:17:09,620 looking at the moon they're used to 437 00:17:13,870 --> 00:17:11,540 looking at very faint objects galactic 438 00:17:15,490 --> 00:17:13,880 extra galactic objects the Moon moves a 439 00:17:17,260 --> 00:17:15,500 different rate than a lot of other 440 00:17:19,120 --> 00:17:17,270 things that the astronomers observe so 441 00:17:21,070 --> 00:17:19,130 it took a lot of planning to be able to 442 00:17:22,360 --> 00:17:21,080 make this work and the amount of data 443 00:17:23,890 --> 00:17:22,370 that we've gotten in already is a 444 00:17:26,050 --> 00:17:23,900 testament to the success that we've had 445 00:17:27,910 --> 00:17:26,060 based on all of that prep work that we 446 00:17:30,310 --> 00:17:27,920 did before so this is just an example of 447 00:17:32,230 --> 00:17:30,320 one of the impact or one of the mosaics 448 00:17:33,960 --> 00:17:32,240 that we had ahead of time to help with 449 00:17:37,560 --> 00:17:33,970 targeting 450 00:17:39,299 --> 00:17:37,570 to the next slide so here's a zoomed-in 451 00:17:41,250 --> 00:17:39,309 region of that so you're still looking 452 00:17:43,230 --> 00:17:41,260 at the South Pole you can see several of 453 00:17:45,029 --> 00:17:43,240 the nearby craters are labeled and then 454 00:17:47,279 --> 00:17:45,039 you also see the expected plumeria 455 00:17:48,870 --> 00:17:47,289 that's labeled there towards the bottom 456 00:17:50,970 --> 00:17:48,880 I want to call your attention to there's 457 00:17:52,620 --> 00:17:50,980 a very bright sort of ridge line that 458 00:17:54,570 --> 00:17:52,630 goes across and then behind that is a 459 00:17:57,360 --> 00:17:54,580 very dark region this is where where the 460 00:17:59,820 --> 00:17:57,370 plume is expected to have come up based 461 00:18:03,720 --> 00:17:59,830 on our impact location so this is very 462 00:18:06,000 --> 00:18:03,730 good if we go to the next slide give you 463 00:18:08,039 --> 00:18:06,010 another just another example of where 464 00:18:09,299 --> 00:18:08,049 where these telescopes were pointing and 465 00:18:11,279 --> 00:18:09,309 where they're expecting this plume to be 466 00:18:14,070 --> 00:18:11,289 based on our impact location this is 467 00:18:15,840 --> 00:18:14,080 actually a rendering that was created by 468 00:18:18,120 --> 00:18:15,850 our colleagues at NASA's Goddard Space 469 00:18:19,640 --> 00:18:18,130 Flight Center on this is using Lola data 470 00:18:21,960 --> 00:18:19,650 the lunar orbiter laser altimeter 471 00:18:23,100 --> 00:18:21,970 instrument that's aboard the LRO the 472 00:18:26,039 --> 00:18:23,110 Lunar Reconnaissance Orbiter spacecraft 473 00:18:29,039 --> 00:18:26,049 right now and so using this laser 474 00:18:30,510 --> 00:18:29,049 altimetry data our colleagues at Goddard 475 00:18:32,640 --> 00:18:30,520 were able to create renderings of the 476 00:18:34,320 --> 00:18:32,650 lunar surface for us so we had even 477 00:18:35,880 --> 00:18:34,330 better ideas of what to expect when we 478 00:18:38,460 --> 00:18:35,890 were going in and you can see a white 479 00:18:41,220 --> 00:18:38,470 line we call it the dipstick showing the 480 00:18:44,279 --> 00:18:41,230 location of where the impact predict was 481 00:18:47,880 --> 00:18:44,289 for the Centaur except to go to the next 482 00:18:49,890 --> 00:18:47,890 slide so here's another image from the 483 00:18:51,600 --> 00:18:49,900 Apache point observatory in New Mexico 484 00:18:53,070 --> 00:18:51,610 I'm showing you this about these types 485 00:18:55,830 --> 00:18:53,080 of images again because I want you to be 486 00:18:57,390 --> 00:18:55,840 able to pull out that brighter Ridgeline 487 00:18:59,070 --> 00:18:57,400 that's there and then the dark that's 488 00:19:00,899 --> 00:18:59,080 behind it and that's the cabayos region 489 00:19:02,220 --> 00:19:00,909 where we are impacting and we have 490 00:19:03,779 --> 00:19:02,230 images like these at different lighting 491 00:19:05,610 --> 00:19:03,789 conditions and different tilts of the 492 00:19:09,510 --> 00:19:05,620 moon on says we would know exactly where 493 00:19:11,430 --> 00:19:09,520 to be pointing or the next slide here's 494 00:19:13,350 --> 00:19:11,440 an image from Mount aquella and Hawaii 495 00:19:15,360 --> 00:19:13,360 this is from the Keck guider this is 496 00:19:16,830 --> 00:19:15,370 taken last night so we did a practice 497 00:19:18,419 --> 00:19:16,840 run last night as well so we knew 498 00:19:19,560 --> 00:19:18,429 exactly where would be I just want to 499 00:19:21,539 --> 00:19:19,570 point out one of the techniques it's 500 00:19:23,310 --> 00:19:21,549 used to collect these observations so 501 00:19:24,779 --> 00:19:23,320 you see several different creators are 502 00:19:27,930 --> 00:19:24,789 labeled there and different way points 503 00:19:28,919 --> 00:19:27,940 and so typically in astronomy if you're 504 00:19:30,360 --> 00:19:28,929 trying to find something in the sky you 505 00:19:31,919 --> 00:19:30,370 might do star hopping you know where the 506 00:19:33,299 --> 00:19:31,929 stars are they pretty much stay in the 507 00:19:35,340 --> 00:19:33,309 same spot and so you can find the 508 00:19:37,320 --> 00:19:35,350 patterns and hop around we had to adapt 509 00:19:39,510 --> 00:19:37,330 that technique for working on the moon 510 00:19:40,860 --> 00:19:39,520 and so looking at the different lighting 511 00:19:42,750 --> 00:19:40,870 conditions and looking at the region 512 00:19:44,520 --> 00:19:42,760 where we're impacting picked out various 513 00:19:46,220 --> 00:19:44,530 waypoints so that the astronomers can 514 00:19:48,590 --> 00:19:46,230 move the telescopes and then keep 515 00:19:50,060 --> 00:19:48,600 synced up and keep them locked on the 516 00:19:52,460 --> 00:19:50,070 particular region where we needed to be 517 00:19:54,860 --> 00:19:52,470 pointed and you can see the predict area 518 00:19:59,210 --> 00:19:54,870 for the El cross impact is also labeled 519 00:20:01,610 --> 00:19:59,220 there you go to the next so here's a 520 00:20:03,409 --> 00:20:01,620 sample list of some of the observatories 521 00:20:05,720 --> 00:20:03,419 that we have confirmed data was 522 00:20:06,799 --> 00:20:05,730 collected there's a much bigger list 523 00:20:08,870 --> 00:20:06,809 here but I just want to give you a 524 00:20:10,400 --> 00:20:08,880 flavor for the varieties of the 525 00:20:12,289 --> 00:20:10,410 professional telescopes and the 526 00:20:14,330 --> 00:20:12,299 geographic locations so we have the 527 00:20:16,820 --> 00:20:14,340 Canada France Hawaii telescope located 528 00:20:19,039 --> 00:20:16,830 on Hawaii patchy point observatory New 529 00:20:21,620 --> 00:20:19,049 Mexico I nasa's infrared telescope 530 00:20:23,930 --> 00:20:21,630 facility in hawaii the mmt Observatory 531 00:20:26,150 --> 00:20:23,940 in Arizona Magdalena Ridge Observatory 532 00:20:28,370 --> 00:20:26,160 in New Mexico I'll check out in Hawaii 533 00:20:30,680 --> 00:20:28,380 Gemini North in Hawaii and also the 534 00:20:32,240 --> 00:20:30,690 Subaru telescope the Kree astronomy and 535 00:20:34,669 --> 00:20:32,250 space science institute have telescopes 536 00:20:36,980 --> 00:20:34,679 in both Arizona and Korea Mount Wilson 537 00:20:38,810 --> 00:20:36,990 down in Southern California the Air 538 00:20:40,820 --> 00:20:38,820 Force telescopes out in Hawaii as well 539 00:20:42,770 --> 00:20:40,830 the Allen telescope array up in Northern 540 00:20:45,080 --> 00:20:42,780 California Palomar Observatory in 541 00:20:47,330 --> 00:20:45,090 California Lick Observatory not too far 542 00:20:48,380 --> 00:20:47,340 away from here at NASA Ames so these are 543 00:20:50,570 --> 00:20:48,390 just a sampling of some of the 544 00:20:52,100 --> 00:20:50,580 professional ground-based observatories 545 00:20:54,799 --> 00:20:52,110 that have successfully collected data of 546 00:20:56,960 --> 00:20:54,809 the El cross impacts we also had several 547 00:20:59,380 --> 00:20:56,970 space-based observatories that were also 548 00:21:03,260 --> 00:20:59,390 observing el cross now if we go back 549 00:21:04,970 --> 00:21:03,270 back to the yeah thanks so HST Hubble 550 00:21:06,890 --> 00:21:04,980 Space Telescope newly refurbished that 551 00:21:09,409 --> 00:21:06,900 was excellent we needed that and to 552 00:21:11,090 --> 00:21:09,419 enable these el cross impacts so it's a 553 00:21:13,310 --> 00:21:11,100 great way to use this NASA asset to 554 00:21:16,610 --> 00:21:13,320 support another NASA mission we have 555 00:21:17,990 --> 00:21:16,620 confirmation we had imaging from HST at 556 00:21:20,480 --> 00:21:18,000 first we have confirmed that that has 557 00:21:22,220 --> 00:21:20,490 taken place we are following that up 558 00:21:24,110 --> 00:21:22,230 with some spectroscopy so we're looking 559 00:21:25,789 --> 00:21:24,120 at the exosphere of the moon to see how 560 00:21:27,440 --> 00:21:25,799 it could be perturbed I'm Estonian 561 00:21:28,970 --> 00:21:27,450 mentioned from the impacts those 562 00:21:30,620 --> 00:21:28,980 observations are going on now and we're 563 00:21:31,580 --> 00:21:30,630 also taking some in several hours and 564 00:21:33,620 --> 00:21:31,590 then we're taking another one tomorrow 565 00:21:36,169 --> 00:21:33,630 to see how that exosphere actually 566 00:21:38,930 --> 00:21:36,179 evolves and may relax back so we have 567 00:21:42,169 --> 00:21:38,940 confirmation that HST can't keep going 568 00:21:44,780 --> 00:21:42,179 go back yeah I think so HST operations 569 00:21:47,210 --> 00:21:44,790 were nominal expecting data it'll be 570 00:21:48,770 --> 00:21:47,220 downlink soon fortuitously will be able 571 00:21:52,010 --> 00:21:48,780 to get that data down in about an hour 572 00:21:53,930 --> 00:21:52,020 so it's for our first dump there's also 573 00:21:55,549 --> 00:21:53,940 the Lunar Reconnaissance Orbiter so this 574 00:21:57,169 --> 00:21:55,559 is our sister mission that we've been 575 00:21:59,120 --> 00:21:57,179 working with LR oh I'm quite closely 576 00:21:59,960 --> 00:21:59,130 throughout this entire process we 577 00:22:01,970 --> 00:21:59,970 launched with L 578 00:22:04,700 --> 00:22:01,980 oh I'm back in June from the Kennedy 579 00:22:06,110 --> 00:22:04,710 Space Center down in Florida LRO is in 580 00:22:08,240 --> 00:22:06,120 orbit around the moon right now so they 581 00:22:09,800 --> 00:22:08,250 are in a great position to be supporting 582 00:22:12,200 --> 00:22:09,810 el cross and they have done a tremendous 583 00:22:14,450 --> 00:22:12,210 job they have been observing the impact 584 00:22:15,890 --> 00:22:14,460 location before impact so they've been 585 00:22:17,510 --> 00:22:15,900 helping a lot with the site selection 586 00:22:19,130 --> 00:22:17,520 and characterization of where we are 587 00:22:21,920 --> 00:22:19,140 impacting they're taking observations 588 00:22:23,480 --> 00:22:21,930 during the impact as well and we hear 589 00:22:25,340 --> 00:22:23,490 that that went well and they're also 590 00:22:27,080 --> 00:22:25,350 doing follow-up observations afterwards 591 00:22:28,550 --> 00:22:27,090 since they're in and they're in lunar 592 00:22:30,440 --> 00:22:28,560 orbit they're in a great place to take 593 00:22:31,700 --> 00:22:30,450 follow-up observations as Tony had 594 00:22:33,350 --> 00:22:31,710 mentioned before that are very 595 00:22:35,210 --> 00:22:33,360 complimentary to the data that work 596 00:22:37,010 --> 00:22:35,220 that's been collected from the l cross 597 00:22:39,530 --> 00:22:37,020 shepherding spacecraft so we are working 598 00:22:41,870 --> 00:22:39,540 very closely with LR 0 and we actually 599 00:22:43,610 --> 00:22:41,880 appreciate their support a lot there's 600 00:22:45,620 --> 00:22:43,620 also a few other satellites that we have 601 00:22:47,450 --> 00:22:45,630 that have been collecting data is a 602 00:22:49,070 --> 00:22:47,460 Swedish radio telescope called Odin 603 00:22:51,560 --> 00:22:49,080 which is in Earth orbit and they have 604 00:22:53,180 --> 00:22:51,570 successfully collected data during the L 605 00:22:55,070 --> 00:22:53,190 cross impacts that data is already back 606 00:22:57,620 --> 00:22:55,080 down on the ground and it's being 607 00:23:00,230 --> 00:22:57,630 processed right now also we have the 608 00:23:01,760 --> 00:23:00,240 icono satellite was turned towards the 609 00:23:03,740 --> 00:23:01,770 moon we have confirmation that they have 610 00:23:05,750 --> 00:23:03,750 collected their data it will be downlink 611 00:23:07,130 --> 00:23:05,760 soon and so where we had nominal 612 00:23:09,620 --> 00:23:07,140 operations so we're looking forward to 613 00:23:11,510 --> 00:23:09,630 seeing that data and also that GOI one 614 00:23:13,910 --> 00:23:11,520 satellite was also it's in Earth orbit 615 00:23:14,990 --> 00:23:13,920 on earth looking satellite turned it 616 00:23:16,790 --> 00:23:15,000 towards the moon though they 617 00:23:18,560 --> 00:23:16,800 successfully collected data during the L 618 00:23:19,790 --> 00:23:18,570 cross impacts the data has been down 619 00:23:21,710 --> 00:23:19,800 linked to the ground and so we're 620 00:23:26,330 --> 00:23:21,720 expecting to be able to see that later 621 00:23:27,980 --> 00:23:26,340 today okay next slide so I want to show 622 00:23:29,270 --> 00:23:27,990 you just a sampling of some of the 623 00:23:32,630 --> 00:23:29,280 images and data that was collected 624 00:23:34,970 --> 00:23:32,640 during the El cross impacts we're still 625 00:23:36,860 --> 00:23:34,980 working in the process of processing and 626 00:23:38,990 --> 00:23:36,870 analyzing this data so as Tony mentioned 627 00:23:40,970 --> 00:23:39,000 not going to make any claims about the 628 00:23:42,890 --> 00:23:40,980 implications water no water plume 629 00:23:44,660 --> 00:23:42,900 whatever we're just trying to give you a 630 00:23:46,580 --> 00:23:44,670 flavor of the various types of data that 631 00:23:48,230 --> 00:23:46,590 we have that are being process and as 632 00:23:50,000 --> 00:23:48,240 Tony mentioned before we have collected 633 00:23:51,770 --> 00:23:50,010 the data that we needed we collected the 634 00:23:54,050 --> 00:23:51,780 data that we set out to get and so we're 635 00:23:55,970 --> 00:23:54,060 thrilled about that and as scientists 636 00:23:58,400 --> 00:23:55,980 were very excited to delve in and start 637 00:24:01,250 --> 00:23:58,410 the analysis so here you're seeing a 638 00:24:04,610 --> 00:24:01,260 picture from the NASA irts the infrared 639 00:24:05,690 --> 00:24:04,620 telescope facility out in Hawaii you can 640 00:24:07,640 --> 00:24:05,700 see you should be able to pick out you 641 00:24:09,680 --> 00:24:07,650 can see that brighter line at brighter 642 00:24:11,960 --> 00:24:09,690 Ridge and then the darker area behind it 643 00:24:13,520 --> 00:24:11,970 that's the cabayos crater on there on 644 00:24:15,050 --> 00:24:13,530 target acquired the target we're 645 00:24:16,970 --> 00:24:15,060 able to hold the target and collected 646 00:24:18,890 --> 00:24:16,980 data you can see an arrow pointed to the 647 00:24:21,050 --> 00:24:18,900 plume location and where the impact 648 00:24:23,090 --> 00:24:21,060 predict was expected to occur they're 649 00:24:24,620 --> 00:24:23,100 currently analyzing the data and so we 650 00:24:26,780 --> 00:24:24,630 also have spectra as well that are 651 00:24:28,700 --> 00:24:26,790 coming and so we're in the process so I 652 00:24:30,170 --> 00:24:28,710 just want to report that a lot of good 653 00:24:31,880 --> 00:24:30,180 observations from Hawaii I won't be able 654 00:24:36,170 --> 00:24:31,890 to show them all but this is just an 655 00:24:38,240 --> 00:24:36,180 example next here's an image from the 656 00:24:40,490 --> 00:24:38,250 Canada France Hawaii telescope this is 657 00:24:42,890 --> 00:24:40,500 also out in Hawaii this is christian 658 00:24:45,200 --> 00:24:42,900 delay as the director of the sea fht 659 00:24:46,580 --> 00:24:45,210 collected this data and i'll point out 660 00:24:48,050 --> 00:24:46,590 so you can meet you should be able to 661 00:24:49,820 --> 00:24:48,060 pick out cabayos by now so you've got 662 00:24:51,170 --> 00:24:49,830 that bright Ridge I'm sort of towards 663 00:24:53,270 --> 00:24:51,180 the middle with the dark background 664 00:24:56,510 --> 00:24:53,280 behind it I'll very good optimal viewing 665 00:24:58,700 --> 00:24:56,520 conditions you see two dark spots I'm 666 00:25:00,560 --> 00:24:58,710 one right in the middle of the ridge and 667 00:25:02,210 --> 00:25:00,570 then one above the ridge this is where 668 00:25:03,980 --> 00:25:02,220 they're taking much more detailed 669 00:25:05,720 --> 00:25:03,990 measurements and will be analyzing the 670 00:25:07,340 --> 00:25:05,730 data now looking for water so the reason 671 00:25:09,620 --> 00:25:07,350 that there are two spots are collecting 672 00:25:12,080 --> 00:25:09,630 this data one is on the ridge where 673 00:25:13,670 --> 00:25:12,090 you'd expect to see something if kicked 674 00:25:15,830 --> 00:25:13,680 up by L cross and then there's one 675 00:25:17,360 --> 00:25:15,840 that's off of the impact location for 676 00:25:19,310 --> 00:25:17,370 calibration purposes where you expect to 677 00:25:21,140 --> 00:25:19,320 see no change and so that way you can 678 00:25:23,660 --> 00:25:21,150 have a comparison point I'm to see if 679 00:25:25,310 --> 00:25:23,670 you see any change detection in the area 680 00:25:27,680 --> 00:25:25,320 where L cross was intended to hit so 681 00:25:29,870 --> 00:25:27,690 that analysis is going on right now and 682 00:25:34,070 --> 00:25:29,880 we'll be able to report back as soon as 683 00:25:36,950 --> 00:25:34,080 that's done next this is a spectacular 684 00:25:39,830 --> 00:25:36,960 image from the Palomar Observatory using 685 00:25:41,420 --> 00:25:39,840 their adaptive optics mechanism so you 686 00:25:43,190 --> 00:25:41,430 can see you see the bright Ridge and 687 00:25:44,360 --> 00:25:43,200 then you also see the dark behind in 688 00:25:46,190 --> 00:25:44,370 this is taken down in Southern 689 00:25:48,050 --> 00:25:46,200 California and we're very excited about 690 00:25:50,420 --> 00:25:48,060 this type of imagery we're going to do 691 00:25:52,130 --> 00:25:50,430 some more post data processing I would 692 00:25:54,230 --> 00:25:52,140 do enhancements and look at the other 693 00:25:55,940 --> 00:25:54,240 series images that are in the series as 694 00:25:57,800 --> 00:25:55,950 well I just wanted to give you a flavor 695 00:25:59,270 --> 00:25:57,810 of the types and the quality of the 696 00:26:04,520 --> 00:25:59,280 image data that we have been able to 697 00:26:06,560 --> 00:26:04,530 collect from the ground next and for the 698 00:26:08,780 --> 00:26:06,570 scientist we have squiggly lines which 699 00:26:11,210 --> 00:26:08,790 are very exciting Tony explained these 700 00:26:12,620 --> 00:26:11,220 are spectra so we're looking we're 701 00:26:14,360 --> 00:26:12,630 looking in different wavelengths so this 702 00:26:16,910 --> 00:26:14,370 is looking in the near of red this is 703 00:26:19,070 --> 00:26:16,920 from the mmt Observatory in Arizona this 704 00:26:21,080 --> 00:26:19,080 is faith felis and her team have been 705 00:26:23,600 --> 00:26:21,090 doing a tremendous job and so what you 706 00:26:25,539 --> 00:26:23,610 see are one spectra that's before the 707 00:26:26,919 --> 00:26:25,549 impact of the Centaur and one that 708 00:26:29,259 --> 00:26:26,929 after the impact of the Centaur and 709 00:26:30,940 --> 00:26:29,269 anyone can tell that those two squiggly 710 00:26:32,560 --> 00:26:30,950 lines are different we don't know what 711 00:26:34,690 --> 00:26:32,570 that means yet we have to go and 712 00:26:38,259 --> 00:26:34,700 interpret the data and analyze it it's 713 00:26:40,060 --> 00:26:38,269 been some preliminary productions that 714 00:26:41,859 --> 00:26:40,070 have gone on but what we have to look at 715 00:26:43,060 --> 00:26:41,869 this more closely but what we're seeing 716 00:26:45,369 --> 00:26:43,070 is that there's something interesting 717 00:26:46,600 --> 00:26:45,379 that's going on Tony mentioned a lot of 718 00:26:48,369 --> 00:26:46,610 interesting things we're seeing in the 719 00:26:49,989 --> 00:26:48,379 spacecraft data and so now we really 720 00:26:51,669 --> 00:26:49,999 have to go back and do our homework very 721 00:26:54,009 --> 00:26:51,679 meticulously and try and understand 722 00:26:55,840 --> 00:26:54,019 what's going on in all these data sets 723 00:26:59,049 --> 00:26:55,850 and try and come up with a most coherent 724 00:27:01,930 --> 00:26:59,059 story in terms of spectra as well the 725 00:27:05,259 --> 00:27:01,940 Kitt Peak Observatory I'm also detected 726 00:27:07,029 --> 00:27:05,269 a flash with a sodium flash so we had 727 00:27:09,700 --> 00:27:07,039 some emission of sodium that was what's 728 00:27:11,799 --> 00:27:09,710 happening a very strong indication very 729 00:27:13,570 --> 00:27:11,809 brief but very strong and so that folds 730 00:27:15,009 --> 00:27:13,580 into the story as well so there are some 731 00:27:17,499 --> 00:27:15,019 detection from even from the 732 00:27:18,940 --> 00:27:17,509 ground-based as to what was happening at 733 00:27:20,950 --> 00:27:18,950 the time of impact and shortly 734 00:27:22,779 --> 00:27:20,960 thereafter and so we're looking to bring 735 00:27:25,149 --> 00:27:22,789 all these data sets together to try and 736 00:27:26,889 --> 00:27:25,159 understand what's going on I have a few 737 00:27:28,749 --> 00:27:26,899 videos that I'd like to show as well I 738 00:27:30,840 --> 00:27:28,759 should mention here we commissioned we 739 00:27:33,220 --> 00:27:30,850 measured the sodium line but can in our 740 00:27:36,460 --> 00:27:33,230 spectrometer as well so we can 741 00:27:38,139 --> 00:27:36,470 cross-correlate back yeah excellent okay 742 00:27:40,899 --> 00:27:38,149 so the first video that we have playing 743 00:27:43,599 --> 00:27:40,909 here so this is interesting so this is 744 00:27:45,820 --> 00:27:43,609 this is from the Vatican advanced 745 00:27:48,249 --> 00:27:45,830 technology telescope compliments of Dave 746 00:27:50,109 --> 00:27:48,259 Harvey and Chris Johnson in southeastern 747 00:27:51,970 --> 00:27:50,119 Arizona and what you're looking at is a 748 00:27:54,399 --> 00:27:51,980 video of the Centaur taken about six 749 00:27:55,869 --> 00:27:54,409 hours before impact so if you look in 750 00:27:57,629 --> 00:27:55,879 the center you see a bright dot that 751 00:27:59,769 --> 00:27:57,639 sort of stays the same so they are 752 00:28:02,289 --> 00:27:59,779 tracking on the Centaur this is after 753 00:28:04,149 --> 00:28:02,299 separation and then you see stars that 754 00:28:05,950 --> 00:28:04,159 are moving across so we can use this 755 00:28:08,220 --> 00:28:05,960 information to actually track the 756 00:28:13,690 --> 00:28:08,230 Centaur which is very very interesting 757 00:28:15,489 --> 00:28:13,700 now if we go to the next video this is a 758 00:28:17,259 --> 00:28:15,499 video from the Magdalena Ridge 759 00:28:19,989 --> 00:28:17,269 observatory this is out in New Mexico 760 00:28:21,970 --> 00:28:19,999 this is from mark buoy and eileen ryan 761 00:28:23,409 --> 00:28:21,980 out there and this is a neat video too 762 00:28:25,389 --> 00:28:23,419 if you look in the center of the red 763 00:28:26,649 --> 00:28:25,399 circle you can see the Centaur and then 764 00:28:29,049 --> 00:28:26,659 you see the nearby stars that are 765 00:28:32,080 --> 00:28:29,059 stringing by as the Centaur actually 766 00:28:34,029 --> 00:28:32,090 moves across the sky towards the moon so 767 00:28:39,899 --> 00:28:34,039 we'll be looking at this data and even 768 00:28:45,009 --> 00:28:43,419 okay and if we go to the next video so 769 00:28:47,320 --> 00:28:45,019 in these these are videos that were 770 00:28:48,940 --> 00:28:47,330 taken during the time of impact from a 771 00:28:51,279 --> 00:28:48,950 several different observatories this one 772 00:28:54,399 --> 00:28:51,289 is from the 3.5 meter telescope at 773 00:28:57,100 --> 00:28:54,409 Apache point this video runs 15 is sped 774 00:28:58,870 --> 00:28:57,110 up 15 seconds before impact through one 775 00:29:00,789 --> 00:28:58,880 minute and 45 seconds post-impact 776 00:29:02,529 --> 00:29:00,799 Alice's compliments of new mexico state 777 00:29:05,409 --> 00:29:02,539 university in NASA's Marshall Space 778 00:29:07,419 --> 00:29:05,419 Flight Center and so you can see this is 779 00:29:09,220 --> 00:29:07,429 tilted these are we haven't rotated them 780 00:29:11,320 --> 00:29:09,230 yet but you can see up and down you can 781 00:29:12,759 --> 00:29:11,330 see that bright Ridge and then right 782 00:29:13,899 --> 00:29:12,769 behind that you see the dark part so you 783 00:29:16,480 --> 00:29:13,909 know that you're looking at conveyors 784 00:29:17,950 --> 00:29:16,490 crater so we have this type of imagery I 785 00:29:20,080 --> 00:29:17,960 want to show you a few other videos that 786 00:29:22,299 --> 00:29:20,090 we have to show you the range of scales 787 00:29:25,060 --> 00:29:22,309 that we have of the different videos and 788 00:29:27,250 --> 00:29:25,070 images because we purposely have done 789 00:29:28,840 --> 00:29:27,260 this to collect a wide range of 790 00:29:30,700 --> 00:29:28,850 different types of data so we can get as 791 00:29:33,220 --> 00:29:30,710 much information as we can so here for 792 00:29:34,870 --> 00:29:33,230 example is another movie this is a wider 793 00:29:37,509 --> 00:29:34,880 field of view this is the mmt 794 00:29:39,190 --> 00:29:37,519 observatory amount hopkins and so as you 795 00:29:41,080 --> 00:29:39,200 can see this one is more zoomed out and 796 00:29:42,970 --> 00:29:41,090 so this is a time lapse that goes on for 797 00:29:46,000 --> 00:29:42,980 a while and so we can look at different 798 00:29:47,440 --> 00:29:46,010 scales throughout before during and 799 00:29:51,009 --> 00:29:47,450 after impact and that's what we'll be 800 00:29:58,060 --> 00:29:51,019 doing after this if we go to the next 801 00:30:00,820 --> 00:29:58,070 video okay so now you can see so this is 802 00:30:02,830 --> 00:30:00,830 also from the mmt observatory same place 803 00:30:04,269 --> 00:30:02,840 but now you're more zoomed in and so now 804 00:30:06,610 --> 00:30:04,279 you're looking at higher resolution and 805 00:30:08,740 --> 00:30:06,620 so you can see the the lighter band and 806 00:30:11,080 --> 00:30:08,750 then you can see the darker part looking 807 00:30:13,299 --> 00:30:11,090 around Cabaye's crater this is it the 808 00:30:15,730 --> 00:30:13,309 six point five meter guide camera with 809 00:30:17,980 --> 00:30:15,740 no filter and this goes throughout the 810 00:30:19,659 --> 00:30:17,990 course of the impact and so we can look 811 00:30:21,310 --> 00:30:19,669 at all these different scales and try 812 00:30:23,110 --> 00:30:21,320 and put all these pieces together I'm 813 00:30:24,940 --> 00:30:23,120 also looking at the data from the 814 00:30:26,799 --> 00:30:24,950 shepherding spacecraft and also the data 815 00:30:28,960 --> 00:30:26,809 from the orbiting assets that will be 816 00:30:31,180 --> 00:30:28,970 available probably to us later this 817 00:30:33,970 --> 00:30:31,190 afternoon once all that data is down 818 00:30:35,019 --> 00:30:33,980 links and such so I hope I'd leave you 819 00:30:36,490 --> 00:30:35,029 with the message that we have a 820 00:30:37,889 --> 00:30:36,500 tremendous amount of data that was 821 00:30:40,180 --> 00:30:37,899 collected through the observing campaign 822 00:30:42,610 --> 00:30:40,190 ground-based and space-based how the 823 00:30:44,680 --> 00:30:42,620 team has worked together phenomenally to 824 00:30:46,480 --> 00:30:44,690 make sure that this happens and we'll 825 00:30:48,399 --> 00:30:46,490 continue to work together with the el 826 00:30:49,120 --> 00:30:48,409 cross science team and try and put the 827 00:30:53,770 --> 00:30:49,130 pieces together 828 00:30:55,900 --> 00:30:53,780 it's going to be seemly exciting and now 829 00:30:58,840 --> 00:30:55,910 hand it over to Mike Margo thanks an 830 00:31:00,600 --> 00:30:58,850 awful lot jen well you can tell by 831 00:31:02,700 --> 00:31:00,610 everything that we've heard here that 832 00:31:05,230 --> 00:31:02,710 you've been drinking from the firehose 833 00:31:08,220 --> 00:31:05,240 there is an enormous amount of data that 834 00:31:11,980 --> 00:31:08,230 we've we've gotten today not just from 835 00:31:15,370 --> 00:31:11,990 from Elk Ross but from assets around the 836 00:31:17,800 --> 00:31:15,380 world and it's going to be a little 837 00:31:20,260 --> 00:31:17,810 tough for me to try to bring the whole 838 00:31:22,300 --> 00:31:20,270 thing together but I'm going to try to 839 00:31:26,830 --> 00:31:22,310 take things up and bring you some 840 00:31:30,610 --> 00:31:26,840 context for what L cross has has meant 841 00:31:34,690 --> 00:31:30,620 for exploration systems for science and 842 00:31:36,070 --> 00:31:34,700 for and for NASA and really the one 843 00:31:39,240 --> 00:31:36,080 thing that I think really stands out 844 00:31:42,190 --> 00:31:39,250 here is this is NASA at it's very best 845 00:31:45,430 --> 00:31:42,200 what you're seeing here is exploration 846 00:31:48,520 --> 00:31:45,440 and science working together to provide 847 00:31:51,000 --> 00:31:48,530 great information for both this is going 848 00:31:55,330 --> 00:31:51,010 to change the way we look at the moon 849 00:31:58,240 --> 00:31:55,340 scientifically and inform our abilities 850 00:32:03,010 --> 00:31:58,250 to and our planning for continuing to 851 00:32:05,710 --> 00:32:03,020 explore the solar system we have clearly 852 00:32:09,550 --> 00:32:05,720 an outstanding team that has just done a 853 00:32:11,650 --> 00:32:09,560 magnificent job they took a advantage of 854 00:32:15,250 --> 00:32:11,660 a an opportunity that was made available 855 00:32:19,050 --> 00:32:15,260 to them they were nimble they delivered 856 00:32:23,430 --> 00:32:19,060 a outstanding spacecraft on time and 857 00:32:25,980 --> 00:32:23,440 within budget this is a great lesson of 858 00:32:32,680 --> 00:32:25,990 for NASA it's a new tool in our toolbox 859 00:32:37,600 --> 00:32:32,690 for how we can continue to explore oh it 860 00:32:40,210 --> 00:32:37,610 all started and it continued starting at 861 00:32:43,990 --> 00:32:40,220 the very top Oh with the associate 862 00:32:47,080 --> 00:32:44,000 administrators of exploration system 863 00:32:50,470 --> 00:32:47,090 starting with doc Horowitz and Rick Gill 864 00:32:53,050 --> 00:32:50,480 brick and and now Doug cook and of 865 00:32:54,820 --> 00:32:53,060 course we can't forget the outstanding 866 00:32:57,240 --> 00:32:54,830 support that we got from the center 867 00:33:00,820 --> 00:32:57,250 director here at Ames Pete worden of 868 00:33:02,810 --> 00:33:00,830 having that kind of support let this 869 00:33:07,549 --> 00:33:02,820 team go off and do what they 870 00:33:09,499 --> 00:33:07,559 needed to do to be successful today this 871 00:33:11,899 --> 00:33:09,509 is really a story of teamwork and I 872 00:33:14,990 --> 00:33:11,909 think you've heard that certainly from 873 00:33:18,549 --> 00:33:15,000 Jen but it's bigger than that uh we have 874 00:33:22,240 --> 00:33:18,559 uh not just the other NASA missions of 875 00:33:24,830 --> 00:33:22,250 of LR 0 and the Hubble Space Telescope 876 00:33:27,590 --> 00:33:24,840 but other international missions that 877 00:33:30,560 --> 00:33:27,600 were key in helping us develop the 878 00:33:33,409 --> 00:33:30,570 planning for the impact as well as the 879 00:33:37,399 --> 00:33:33,419 analysis that's being done it started 880 00:33:39,619 --> 00:33:37,409 with getting high resolution altimeter 881 00:33:42,169 --> 00:33:39,629 II information from our colleagues at 882 00:33:46,149 --> 00:33:42,179 Jackson in Japan with the kagyu 883 00:33:48,379 --> 00:33:46,159 spacecraft we also were able to get a 884 00:33:51,860 --> 00:33:48,389 radar data from the chandrayaan-1 885 00:33:53,690 --> 00:33:51,870 spacecraft from India and an important 886 00:33:56,600 --> 00:33:53,700 instrument in for this in helping 887 00:33:59,299 --> 00:33:56,610 targeting uh where L cross was going to 888 00:34:01,490 --> 00:33:59,309 impact was our lunar exploration Neutron 889 00:34:06,649 --> 00:34:01,500 detector on Lunar Reconnaissance Orbiter 890 00:34:11,990 --> 00:34:06,659 and that's provided by Russia Oh Jen 891 00:34:14,740 --> 00:34:12,000 gave a really a extensive discussion of 892 00:34:16,700 --> 00:34:14,750 the the teamwork that we got from 893 00:34:19,149 --> 00:34:16,710 astronomers both here in the United 894 00:34:22,010 --> 00:34:19,159 States as well as around the world of 895 00:34:26,119 --> 00:34:22,020 what we see is that the success here 896 00:34:27,530 --> 00:34:26,129 today is really our L cross team really 897 00:34:29,720 --> 00:34:27,540 being able to stand on the shoulders of 898 00:34:33,280 --> 00:34:29,730 an awful lot of other teams that have 899 00:34:36,260 --> 00:34:33,290 really done an outstanding job today 900 00:34:39,710 --> 00:34:36,270 when we step back and look at what the 901 00:34:42,050 --> 00:34:39,720 potential for the results are it almost 902 00:34:45,950 --> 00:34:42,060 seems like a dichotomy to me it's both 903 00:34:48,109 --> 00:34:45,960 timely as well as timeless over the 904 00:34:49,940 --> 00:34:48,119 course of the last couple of weeks we've 905 00:34:52,460 --> 00:34:49,950 really been thinking about the moon in a 906 00:34:54,919 --> 00:34:52,470 different way who thought just a month 907 00:34:57,109 --> 00:34:54,929 or so ago that we'd be talking about the 908 00:35:00,290 --> 00:34:57,119 water cycle where the hydration cycle of 909 00:35:02,829 --> 00:35:00,300 the moon well now we do think that way 910 00:35:07,309 --> 00:35:02,839 we used to think of the moon as this 911 00:35:09,680 --> 00:35:07,319 desolate unchanging place over millions 912 00:35:11,990 --> 00:35:09,690 and even billions of years now we're 913 00:35:14,690 --> 00:35:12,000 seeing that there is a dynamic to the 914 00:35:16,160 --> 00:35:14,700 moon that's really changing on a 915 00:35:18,589 --> 00:35:16,170 day-by-day 916 00:35:21,440 --> 00:35:18,599 by month kind of basis so we're really 917 00:35:24,640 --> 00:35:21,450 looking at an international effort now 918 00:35:30,559 --> 00:35:24,650 across a number of spacefaring nations 919 00:35:33,620 --> 00:35:30,569 of looking at the moon and just prodding 920 00:35:35,420 --> 00:35:33,630 the moon to give up her her deepest and 921 00:35:39,920 --> 00:35:35,430 darkest secrets and we're seeing a 922 00:35:41,990 --> 00:35:39,930 perfect example that of today but not 923 00:35:45,859 --> 00:35:42,000 only is this timely in providing an 924 00:35:48,380 --> 00:35:45,869 important piece of the puzzle of water 925 00:35:51,049 --> 00:35:48,390 on the moon but also this date is 926 00:35:56,349 --> 00:35:51,059 timeless this data is going to be 927 00:36:00,230 --> 00:35:56,359 available to NASA and the other 928 00:36:02,180 --> 00:36:00,240 explorers to plan for the future and how 929 00:36:04,640 --> 00:36:02,190 we're going to explore the solar system 930 00:36:09,079 --> 00:36:04,650 that data is good and that information 931 00:36:11,870 --> 00:36:09,089 is going to be there when we need it you 932 00:36:14,480 --> 00:36:11,880 know when I was trying to get some sleep 933 00:36:18,410 --> 00:36:14,490 last night I was laying back there and I 934 00:36:20,690 --> 00:36:18,420 just went back about 40 years now about 935 00:36:22,670 --> 00:36:20,700 40 years we know was when Apollo 11 936 00:36:25,880 --> 00:36:22,680 landed I had just graduated from high 937 00:36:27,950 --> 00:36:25,890 school from a small town in western 938 00:36:29,900 --> 00:36:27,960 western Pennsylvania called clairton and 939 00:36:31,010 --> 00:36:29,910 of course you know after graduation a 940 00:36:33,440 --> 00:36:31,020 bunch of us are sitting around saying 941 00:36:36,470 --> 00:36:33,450 what well what are you going to do and 942 00:36:38,839 --> 00:36:36,480 you know I remember saying that one of 943 00:36:42,530 --> 00:36:38,849 the reasons I'm going to college is that 944 00:36:44,030 --> 00:36:42,540 I want to work with NASA I want to 945 00:36:46,280 --> 00:36:44,040 explore I want to explore through 946 00:36:48,140 --> 00:36:46,290 science I want to continue to explore 947 00:36:51,440 --> 00:36:48,150 the moon well that's exactly what we've 948 00:36:53,089 --> 00:36:51,450 been doing today and I'm sure that there 949 00:36:55,789 --> 00:36:53,099 are an awful lot of young explorers out 950 00:36:58,549 --> 00:36:55,799 there right now that are thinking and 951 00:37:01,730 --> 00:36:58,559 dreaming the same kind of dreams that 952 00:37:03,260 --> 00:37:01,740 I've had and I continue to have and that 953 00:37:05,539 --> 00:37:03,270 shows that you know one of the really 954 00:37:10,069 --> 00:37:05,549 outstanding things that NASA does and 955 00:37:12,740 --> 00:37:10,079 does best and that is we make dreams 956 00:37:15,920 --> 00:37:12,750 come true and we make dreams come true 957 00:37:22,660 --> 00:37:15,930 for for us as individuals for us as a 958 00:37:26,240 --> 00:37:22,670 nation and and for the world of you know 959 00:37:27,859 --> 00:37:26,250 we've all had our thoughts of what's 960 00:37:29,989 --> 00:37:27,869 been happening today well you can 961 00:37:31,969 --> 00:37:29,999 imagine around the around the country 962 00:37:33,229 --> 00:37:31,979 there are an awful lot of other folks 963 00:37:36,289 --> 00:37:33,239 who have been thinking about this and 964 00:37:38,749 --> 00:37:36,299 we're lucky enough to have with us the 965 00:37:42,169 --> 00:37:38,759 message from some folks I think we might 966 00:37:44,449 --> 00:37:42,179 want to hear from we have Doug cook 967 00:37:46,489 --> 00:37:44,459 who's the associate administrator for 968 00:37:49,399 --> 00:37:46,499 the exploration systems Mission 969 00:37:51,739 --> 00:37:49,409 Directorate lori Garver the deputy 970 00:37:58,309 --> 00:37:51,749 administrator of NASA and Charlie Bolden 971 00:38:00,649 --> 00:37:58,319 the NASA Administrator I rusty D'Antoni 972 00:38:02,359 --> 00:38:00,659 and all of your team i'm here with lori 973 00:38:04,879 --> 00:38:02,369 Garver and Doug cook we're at the 974 00:38:06,019 --> 00:38:04,889 Newseum in Washington DC sorry we 975 00:38:07,489 --> 00:38:06,029 couldn't be out there with you but we 976 00:38:09,049 --> 00:38:07,499 were here and the excitement was 977 00:38:11,089 --> 00:38:09,059

at the screen this 986 00:38:30,979 --> 00:38:28,649 is what NASA delivers best thank you so 987 00:38:33,439 --> 00:38:30,989 much it's a great day yes and I want to 988 00:38:35,989 --> 00:38:33,449 say a special thanks to the to the NASA 989 00:38:37,399 --> 00:38:35,999 team led by Dan Andrews and a northrop 990 00:38:42,079 --> 00:38:37,409 grumman team who have done a fantastic 991 00:38:45,259 --> 00:38:42,089 job on a cost count low cost spacecraft 992 00:38:47,449 --> 00:38:45,269 that did a remarkable job through a lot 993 00:38:49,699 --> 00:38:47,459 of adversity along the way but delivered 994 00:38:51,589 --> 00:38:49,709 him and i was watching the accuracies 995 00:38:53,029 --> 00:38:51,599 along the way and it just put her you 996 00:38:56,599 --> 00:38:53,039 guys

--> 00:39:12,570 now that we have our things done we'll 1000 00:39:17,150 --> 00:39:14,880 take questions from the audience we have 1001 00:39:20,840 --> 00:39:17,160 John Johnson here then we'll go over 1002 00:39:25,700 --> 00:39:20,850 here and then Mike meet them at the two 1003 00:39:28,220 --> 00:39:25,710 gentlemen friend John Johnson los 1004 00:39:29,960 --> 00:39:28,230 angeles times I your you're all talking 1005 00:39:32,330 --> 00:39:29,970 about this as though it's a big success 1006 00:39:34,040 --> 00:39:32,340 but one of the things that the public 1007 00:39:36,050 --> 00:39:34,050 was out there to see today and that we 1008 00:39:38,630 --> 00:39:36,060 were expecting to see was a debris cloud 1009 00:39:41,360 --> 00:39:38,640 and we saw nothing how do you know this 1010 00:39:45,110 --> 00:39:41,370 is a success and that it didn't just hit 1011 00:39:46,430 --> 00:39:45,120 bedrock and nothing came up that's 1012 00:39:47,990 --> 00:39:46,440 that's for me well we need to go back 1013 00:39:53,240 --> 00:39:48,000 and look at the data and see what what 1014 00:39:56,240 --> 00:39:53,250 it says that's exploration has surprises 1015 00:39:58,340 --> 00:39:56,250 in it I'm certainly glad we built our 1016 00:40:02,720 --> 00:39:58,350 mission plan or science plan around all 1017 00:40:07,340 --> 00:40:02,730 aspects of the impact for sure that 1018 00:40:09,350 --> 00:40:07,350 built in that robustness I we need to go 1019 00:40:12,320 --> 00:40:09,360 and carefully look at the images you 1020 00:40:14,540 --> 00:40:12,330 know see what's in them certainly what 1021 00:40:16,760 --> 00:40:14,550 streamed out to the video is not that 1022 00:40:19,160 --> 00:40:16,770 the same fidelity is what we get fresh 1023 00:40:20,450 --> 00:40:19,170 off the spacecraft so we just need to 1024 00:40:22,220 --> 00:40:20,460 look a little bit more closer before we 1025 00:40:27,830 --> 00:40:22,230 conclude anything about an ejector cloud 1026 00:40:29,300 --> 00:40:27,840 or not I see something in the 1027 00:40:30,800 --> 00:40:29,310 spectrometer data but I can't say 1028 00:40:32,240 --> 00:40:30,810 anything more than that de spectrometers 1029 00:40:35,570 --> 00:40:32,250 are more sensitive to the camp than the 1030 00:40:38,660 --> 00:40:35,580 cameras so we go back and look at the 1031 00:40:40,700 --> 00:40:38,670 date is three hours two and a half hours 1032 00:40:42,920 --> 00:40:40,710 old so we'll be meeting later this 1033 00:40:45,050 --> 00:40:42,930 afternoon after getting some rest the 1034 00:40:46,880 --> 00:40:45,060 science team well and we'll be able to 1035 00:40:50,930 --> 00:40:46,890 delve into it right away get more 1036 00:40:53,690 --> 00:40:50,940 answers hi Peter Henderson from Reuters 1037 00:40:56,900 --> 00:40:53,700 um Tony I guess this is for you as well 1038 00:41:00,200 --> 00:40:56,910 I if you can see a would you say a 1039 00:41:03,770 --> 00:41:00,210 sulfur flash does that why sodium sodium 1040 00:41:07,430 --> 00:41:03,780 gosh can't you see if there's a hydrogen 1041 00:41:10,200 --> 00:41:07,440 oxygen flash as well yes we can great 1042 00:41:14,940 --> 00:41:10,210 was there have not looked it 1043 00:41:17,970 --> 00:41:14,950 oh come on I am NOT I spent the last 1044 00:41:20,040 --> 00:41:17,980 hour making those images i showed you we 1045 00:41:23,790 --> 00:41:20,050 have the spectra we have the Flash data 1046 00:41:26,550 --> 00:41:23,800 and you can bet that's the first place 1047 00:41:28,320 --> 00:41:26,560 I'm going after this is to go back and 1048 00:41:30,300 --> 00:41:28,330 look at the spectra itself we have not 1049 00:41:32,250 --> 00:41:30,310 honestly looked at the spectra 1050 00:41:35,040 --> 00:41:32,260 themselves except to do a quality check 1051 00:41:36,660 --> 00:41:35,050 on the radiance figures i showed it's 1052 00:41:38,040 --> 00:41:36,670 just that I think aside from the ejecta 1053 00:41:40,560 --> 00:41:38,050 cloud that's the thing we're all 1054 00:41:41,970 --> 00:41:40,570 wondering can you just call your buddies 1055 00:41:45,030 --> 00:41:41,980 who are probably looking at the data 1056 00:41:46,020 --> 00:41:45,040 right now and let us know I can but I 1057 00:41:51,000 --> 00:41:46,030 think they're all in the audience 1058 00:41:54,990 --> 00:41:51,010 actually right now so yeah there's Kim I 1059 00:41:57,150 --> 00:41:55,000 know she's not so now we we just got to 1060 00:42:00,930 --> 00:41:57,160 sit back and be careful we don't want to 1061 00:42:02,700 --> 00:42:00,940 again it's work life is full of 1062 00:42:05,630 --> 00:42:02,710 surprises want to be careful not make a 1063 00:42:09,450 --> 00:42:05,640 false negative or false positive claim 1064 00:42:11,310 --> 00:42:09,460 I'm excited we saw variations in the 1065 00:42:14,010 --> 00:42:11,320 spectra because that means we saw 1066 00:42:17,040 --> 00:42:14,020 something and it was not just blackness 1067 00:42:19,020 --> 00:42:17,050 and so the information is there we just 1068 00:42:21,030 --> 00:42:19,030 need to get to it do you think you'll 1069 00:42:25,140 --> 00:42:21,040 know later this afternoon then whether 1070 00:42:26,880 --> 00:42:25,150 there's water or ice I very many I 1071 00:42:31,290 --> 00:42:26,890 probably will but I'm not going to tell 1072 00:42:33,480 --> 00:42:31,300 you and so we have a consensus amongst 1073 00:42:35,900 --> 00:42:33,490 team members HST data is just coming 1074 00:42:38,880 --> 00:42:35,910 down now they're looking at oho missions 1075 00:42:40,680 --> 00:42:38,890 lamp on ella rose looking multiple 1076 00:42:44,280 --> 00:42:40,690 orbits you know we're going to take our 1077 00:42:47,790 --> 00:42:44,290 time and get a you know build up a case 1078 00:42:49,530 --> 00:42:47,800 for water and in the ejecta if it's 1079 00:42:51,960 --> 00:42:49,540 there or a case against it if it's not 1080 00:42:54,420 --> 00:42:51,970 there and then understand if if we're 1081 00:42:56,220 --> 00:42:54,430 seeing variations what do these 1082 00:42:58,760 --> 00:42:56,230 variations mean we got to understand 1083 00:43:02,520 --> 00:42:58,770 that and before we say anything honestly 1084 00:43:04,349 --> 00:43:02,530 so I'm thrilled that not only us solve 1085 00:43:07,620 --> 00:43:04,359 variations that's a very good sign and 1086 00:43:10,620 --> 00:43:07,630 the spectra this spectra is where the 1087 00:43:16,760 --> 00:43:10,630 science isn't it's where the information 1088 00:43:19,920 --> 00:43:16,770 is contained so that's that was our most 1089 00:43:23,069 --> 00:43:19,930 highest priority data set so why we got 1090 00:43:25,019 --> 00:43:23,079 that we are going to work on this 1091 00:43:26,999 --> 00:43:25,029 virtually as you might expect and we're 1092 00:43:30,839 --> 00:43:27,009 going to keep everyone abreast as it 1093 00:43:32,819 --> 00:43:30,849 goes forward it's Frank Braun from the 1094 00:43:35,609 --> 00:43:32,829 brown journal of world affairs this is 1095 00:43:37,469 --> 00:43:35,619 really a two-part question here first 1096 00:43:41,309 --> 00:43:37,479 part has to do with the Hubble telescope 1097 00:43:43,109 --> 00:43:41,319 you do you expect that they'll if there 1098 00:43:45,660 --> 00:43:43,119 was a plume there would be an image of 1099 00:43:47,489 --> 00:43:45,670 that plume more distinctly observable 1100 00:43:50,609 --> 00:43:47,499 from the images from the Hubble or have 1101 00:43:53,039 --> 00:43:50,619 there been the way we've structured the 1102 00:43:56,009 --> 00:43:53,049 Hubble observations is highly focused on 1103 00:43:57,509 --> 00:43:56,019 spectroscopy so Tony's been harping on 1104 00:44:00,410 --> 00:43:57,519 this that the spectroscopy is where the 1105 00:44:02,400 --> 00:44:00,420 science is visible and so we're using 1106 00:44:03,809 --> 00:44:02,410 while we're looking at the spectra of 1107 00:44:05,370 --> 00:44:03,819 you know looking at the wavelengths to 1108 00:44:08,279 --> 00:44:05,380 get that diagnostic fingerprint of 1109 00:44:11,009 --> 00:44:08,289 anything perturb the exosphere what is 1110 00:44:13,650 --> 00:44:11,019 that when did it happen so that's the 1111 00:44:14,999 --> 00:44:13,660 that's the price yeah the HST cannot 1112 00:44:17,430 --> 00:44:15,009 look at the moon except in the most 1113 00:44:20,699 --> 00:44:17,440 narrow filters because it is so bright 1114 00:44:22,620 --> 00:44:20,709 so the way we've coordinated with HST is 1115 00:44:26,039 --> 00:44:22,630 for them to look off of the limb of the 1116 00:44:28,049 --> 00:44:26,049 moon and do long integration stairs to 1117 00:44:31,199 --> 00:44:28,059 look for o-h emission lines and vapor 1118 00:44:33,420 --> 00:44:31,209 vapor cloud emissions so that's the 1119 00:44:34,979 --> 00:44:33,430 purpose of HST second part of the 1120 00:44:36,630 --> 00:44:34,989 question is if I understand this 1121 00:44:40,279 --> 00:44:36,640 correctly then there is a doubt whether 1122 00:44:42,630 --> 00:44:40,289 they're in fact was a plume or not we 1123 00:44:44,579 --> 00:44:42,640 just haven't been able to see it clearly 1124 00:44:47,819 --> 00:44:44,589 in our image data yet so we need to go 1125 00:44:50,609 --> 00:44:47,829 back and look at it more closely yeah if 1126 00:44:53,160 --> 00:44:50,619 I could make one more comment and that 1127 00:44:55,469 --> 00:44:53,170 is we're right now you can almost think 1128 00:44:59,039 --> 00:44:55,479 are a number of folks are thinking that 1129 00:45:02,670 --> 00:44:59,049 hey it's over but if there is the 1130 00:45:05,430 --> 00:45:02,680 remnants of the disturbances to thee to 1131 00:45:08,939 --> 00:45:05,440 the exosphere they are far longer live 1132 00:45:11,339 --> 00:45:08,949 to than just the material being ejected 1133 00:45:13,009 --> 00:45:11,349 and then falling back to to the surface 1134 00:45:17,489 --> 00:45:13,019 of the Moon so there will be ongoing 1135 00:45:19,319 --> 00:45:17,499 observations to look at any perturb 1136 00:45:23,400 --> 00:45:19,329 answers or any changes in the in the 1137 00:45:26,309 --> 00:45:23,410 exosphere around the impact site and and 1138 00:45:28,329 --> 00:45:26,319 those observations that go on have the 1139 00:45:29,620 --> 00:45:28,339 advantage of having two impacts 1140 00:45:31,059 --> 00:45:29,630 we only had one to look at from the 1141 00:45:33,249 --> 00:45:31,069 Shepherd spacecraft if they get to see 1142 00:45:34,479 --> 00:45:33,259 the Shepherd spacecraft any vapor cloud 1143 00:45:37,569 --> 00:45:34,489 that could have been produced from that 1144 00:45:39,549 --> 00:45:37,579 as well David we just want another while 1145 00:45:42,549 --> 00:45:39,559 I soy tony got Dave Pearlman from the 1146 00:45:46,239 --> 00:45:42,559 San Francisco Chronicle tony is there 1147 00:45:49,329 --> 00:45:46,249 any evidence at all that the shepherding 1148 00:45:53,289 --> 00:45:49,339 satellite on its way down into the 1149 00:45:55,329 --> 00:45:53,299 crater flew through a vapor cloud or 1150 00:45:58,660 --> 00:45:55,339 anything else resembling that we got 1151 00:46:01,180 --> 00:45:58,670 very good high signal-to-noise data on 1152 00:46:04,839 --> 00:46:01,190 our side viewing spectrometer so I 1153 00:46:06,400 --> 00:46:04,849 honestly need to look closely at it I I 1154 00:46:08,799 --> 00:46:06,410 don't want to say yes or no at this 1155 00:46:12,039 --> 00:46:08,809 point we just need time to look at it 1156 00:46:13,120 --> 00:46:12,049 with the team but we got it was it was 1157 00:46:15,009 --> 00:46:13,130 honestly probably the highest 1158 00:46:17,140 --> 00:46:15,019 signal-to-noise data we could hope for 1159 00:46:18,519 --> 00:46:17,150 so if there's something there we're 1160 00:46:21,370 --> 00:46:18,529 probably going to have a good chance of 1161 00:46:25,839 --> 00:46:21,380 seeing it the fact that we saw a remnant 1162 00:46:28,329 --> 00:46:25,849 crater and we had data as far down as we 1163 00:46:30,579 --> 00:46:28,339 had is very promising very hopeful 1164 00:46:32,319 --> 00:46:30,589 because we we would get into the deepest 1165 00:46:36,249 --> 00:46:32,329 part of any kind of vapor cloud that 1166 00:46:39,009 --> 00:46:36,259 existed just on my initial eyeballing 1167 00:46:41,319 --> 00:46:39,019 from that those last few images of the 1168 00:46:43,569 --> 00:46:41,329 crater it looks to be about the size of 1169 00:46:45,309 --> 00:46:43,579 what we were predicting so that was very 1170 00:46:47,229 --> 00:46:45,319 encouraging have filled a full pixel of 1171 00:46:49,209 --> 00:46:47,239 the camera towards the end and even a 1172 00:46:52,180 --> 00:46:49,219 little bit beyond which means it was 1173 00:46:56,709 --> 00:46:52,190 probably in the 18 to 20 or more meter 1174 00:47:01,329 --> 00:46:56,719 range and to follow that up would the 1175 00:47:03,219 --> 00:47:01,339 mass of ejecta be likely to conform to 1176 00:47:05,170 --> 00:47:03,229 the predictions you made I won't say 1177 00:47:11,380 --> 00:47:05,180 predictions guesses your predictions 1178 00:47:13,719 --> 00:47:11,390 their prediction immediate is but that 1179 00:47:17,109 --> 00:47:13,729 remains to be seen I I can't answer that 1180 00:47:21,940 --> 00:47:17,119 right now that's right okay no we have a 1181 00:47:26,050 --> 00:47:24,670 the points that I heard early on was 1182 00:47:28,839 --> 00:47:26,060 that you were concerned about whether 1183 00:47:31,390 --> 00:47:28,849 the Centaur would spin properly so that 1184 00:47:33,700 --> 00:47:31,400 it would go in in right and therefore 1185 00:47:36,220 --> 00:47:33,710 the shepherding spacecraft could follow 1186 00:47:38,770 --> 00:47:36,230 did how did all that part of the mission 1187 00:47:42,069 --> 00:47:38,780 actually go the tip-off seemed very 1188 00:47:44,620 --> 00:47:42,079 clean we have and that again was nice as 1189 00:47:46,630 --> 00:47:44,630 our cameras work very well and this is 1190 00:47:48,910 --> 00:47:46,640 where I was a bit surprised how well 1191 00:47:50,710 --> 00:47:48,920 they worked that we were able to 1192 00:47:52,210 --> 00:47:50,720 essentially track the center all the way 1193 00:47:54,130 --> 00:47:52,220 up to the end of our operation very 1194 00:47:57,130 --> 00:47:54,140 clearly so we can actually derive that 1195 00:47:59,530 --> 00:47:57,140 that rate the images you saw of the 1196 00:48:02,770 --> 00:47:59,540 center coming in that the telescope's 1197 00:48:06,280 --> 00:48:02,780 made you can kind of see him flicker or 1198 00:48:07,870 --> 00:48:06,290 come and go that could be possibly due 1199 00:48:10,210 --> 00:48:07,880 to a tumble we think there was public 1200 00:48:12,310 --> 00:48:10,220 there was some small tumble to it which 1201 00:48:15,760 --> 00:48:12,320 is actually not necessarily a bad thing 1202 00:48:18,010 --> 00:48:15,770 it's a we kind of wanted to avoid a very 1203 00:48:21,339 --> 00:48:18,020 peculiar a particular impact perfectly 1204 00:48:23,710 --> 00:48:21,349 end on our perfectly flat and in any 1205 00:48:25,030 --> 00:48:23,720 case we can go back and look and see 1206 00:48:26,020 --> 00:48:25,040 what kind of a tumble right there is so 1207 00:48:27,579 --> 00:48:26,030 we have that again we have the 1208 00:48:33,480 --> 00:48:27,589 information we just need to go back now 1209 00:48:35,740 --> 00:48:33,490 and really sit through it ok next please 1210 00:48:38,280 --> 00:48:35,750 remind everyone to please state your 1211 00:48:40,720 --> 00:48:38,290 name and your affiliation thank you 1212 00:48:42,670 --> 00:48:40,730 semanek with discovery channel canada 1213 00:48:45,280 --> 00:48:42,680 immediately after the impact there was 1214 00:48:47,170 --> 00:48:45,290 some discussion about whether the gain 1215 00:48:49,720 --> 00:48:47,180 on the camera especially in the visible 1216 00:48:52,030 --> 00:48:49,730 camera was set right to actually see the 1217 00:48:54,880 --> 00:48:52,040 plume i'm wondering if that has now been 1218 00:48:58,150 --> 00:48:54,890 ruled out as a scenario for the no I 1219 00:49:00,250 --> 00:48:58,160 know it hasn't that's setting gains on 1220 00:49:02,730 --> 00:49:00,260 cameras is tricky you know most people 1221 00:49:05,550 --> 00:49:02,740 get a couple tries at this and our 1222 00:49:08,770 --> 00:49:05,560 visible camera actually has an auto game 1223 00:49:10,089 --> 00:49:08,780 and it's fixed in auto gain so for the 1224 00:49:11,620 --> 00:49:10,099 impact we go to our near infrared 1225 00:49:13,930 --> 00:49:11,630 cameras where we can control the game 1226 00:49:16,120 --> 00:49:13,940 and we were actively controlling in a 1227 00:49:19,690 --> 00:49:16,130 Kim medico the payload scientists in 1228 00:49:23,589 --> 00:49:19,700 besok did a spectacular job managing the 1229 00:49:26,140 --> 00:49:23,599 exposures but also the the data rate we 1230 00:49:28,210 --> 00:49:26,150 have a fixed data rate it snow storm 1231 00:49:30,640 --> 00:49:28,220 forward so we have to live within that 1232 00:49:33,370 --> 00:49:30,650 and actually as we come in the image 1233 00:49:34,320 --> 00:49:33,380 size changes as the complexity of the 1234 00:49:36,300 --> 00:49:34,330 terrain changes 1235 00:49:39,900 --> 00:49:36,310 so we're constantly having to actually 1236 00:49:43,320 --> 00:49:39,910 manage both those real time we need to 1237 00:49:45,240 --> 00:49:43,330 go back and look we I think Kim and the 1238 00:49:47,130 --> 00:49:45,250 team the payload team marks really the 1239 00:49:50,300 --> 00:49:47,140 payload lead and the flight director and 1240 00:49:52,590 --> 00:49:50,310 command to a spectacular job we 1241 00:49:54,780 --> 00:49:52,600 typically if we have a problem we drop 1242 00:49:57,120 --> 00:49:54,790 in inches we did we they don't get 1243 00:50:01,290 --> 00:49:57,130 through I think we maybe had 40 images 1244 00:50:04,290 --> 00:50:01,300 dropped out of thousands so we did 1245 00:50:06,150 --> 00:50:04,300 really good there the game was nice 1246 00:50:08,670 --> 00:50:06,160 about these cameras is they've got a 1247 00:50:10,950 --> 00:50:08,680 pretty large dynamic range and one of 1248 00:50:13,380 --> 00:50:10,960 the things we need to go back and look 1249 00:50:15,210 --> 00:50:13,390 closely just looking at it there you see 1250 00:50:16,770 --> 00:50:15,220 bright peaks and a dark background we 1251 00:50:18,630 --> 00:50:16,780 need to go in there just some co adding 1252 00:50:19,890 --> 00:50:18,640 some stretching and see what we can see 1253 00:50:21,210 --> 00:50:19,900 we just haven't had the chance to do 1254 00:50:23,730 --> 00:50:21,220 that and just a quick follow-up for 1255 00:50:25,320 --> 00:50:23,740 Jennifer I know the second impact would 1256 00:50:28,560 --> 00:50:25,330 have been smaller than the first one was 1257 00:50:30,990 --> 00:50:28,570 the expected debris plume what was that 1258 00:50:34,220 --> 00:50:31,000 also expected to have been seen from the 1259 00:50:37,860 --> 00:50:34,230 earth observing angle Oh from the earth 1260 00:50:39,780 --> 00:50:37,870 yeah yeah just barely maybe it's a 1261 00:50:41,970 --> 00:50:39,790 denser spacecraft so it has a little bit 1262 00:50:44,250 --> 00:50:41,980 higher flight velocity we are hoping 1263 00:50:46,700 --> 00:50:44,260 thinking but in any case as my quarrel 1264 00:50:49,950 --> 00:50:46,710 pointed out the vapor plume if it hit 1265 00:50:52,470 --> 00:50:49,960 volatiles can expand at a conservative 1266 00:50:56,180 --> 00:50:52,480 faster rate doesn't have gravity pulling 1267 00:50:58,710 --> 00:50:56,190 down on it like the grains do as much so 1268 00:51:03,180 --> 00:50:58,720 yeah hopefully that did produce a little 1269 00:51:06,960 --> 00:51:03,190 bit extra stuff for for lr 0 and h st 1270 00:51:09,210 --> 00:51:06,970 and some of the other assets I'm Theresa 1271 00:51:12,930 --> 00:51:09,220 Garcia with abc7 news in San Francisco 1272 00:51:15,930 --> 00:51:12,940 so if there is no water discovered will 1273 00:51:17,880 --> 00:51:15,940 there be an del cross 2 and if you 1274 00:51:22,410 --> 00:51:17,890 haven't found water is there anything 1275 00:51:24,720 --> 00:51:22,420 else you're looking for there oh boy and 1276 00:51:29,580 --> 00:51:24,730 I'll cross to can I finish up cross one 1277 00:51:34,680 --> 00:51:29,590 first yeah if there's no water you know 1278 00:51:36,570 --> 00:51:34,690 science is science it's we need to see 1279 00:51:38,340 --> 00:51:36,580 what we see you know what made these 1280 00:51:39,870 --> 00:51:38,350 changes in the spectra first of all was 1281 00:51:42,000 --> 00:51:39,880 it an instrument response or was there 1282 00:51:44,040 --> 00:51:42,010 really something there if we don't see 1283 00:51:46,530 --> 00:51:44,050 water what does that tells us something 1284 00:51:48,570 --> 00:51:46,540 about the processes where we hit 1285 00:51:50,520 --> 00:51:48,580 did we hit somebody mentioned bedrock or 1286 00:51:53,250 --> 00:51:50,530 do but when we go back and look at the 1287 00:51:55,530 --> 00:51:53,260 maps and the data no we hit into fluff 1288 00:51:58,230 --> 00:51:55,540 well what does that say why didn't we 1289 00:51:59,820 --> 00:51:58,240 see the water it means it's in the 1290 00:52:01,410 --> 00:51:59,830 certain distribution you know we have to 1291 00:52:03,870 --> 00:52:01,420 make go through that whole process of 1292 00:52:06,660 --> 00:52:03,880 piecing it together the puzzle together 1293 00:52:09,060 --> 00:52:06,670 so if we see water if we don't see water 1294 00:52:11,550 --> 00:52:09,070 both those represent two separate 1295 00:52:13,830 --> 00:52:11,560 individual unique pieces of the puzzle 1296 00:52:17,820 --> 00:52:13,840 that we're going to fit in with all the 1297 00:52:20,310 --> 00:52:17,830 other pieces and certainly el Cross does 1298 00:52:24,120 --> 00:52:20,320 provide a strategic direction forward 1299 00:52:27,450 --> 00:52:24,130 for whatever the agency decides to do it 1300 00:52:30,840 --> 00:52:27,460 is a experiment a sample two samples and 1301 00:52:32,310 --> 00:52:30,850 in a particular location and that data's 1302 00:52:35,100 --> 00:52:32,320 of now available to carry us forward 1303 00:52:38,160 --> 00:52:35,110 decide what we do next were you looking 1304 00:52:39,600 --> 00:52:38,170 for anything else other than water we're 1305 00:52:40,950 --> 00:52:39,610 looking for just about everything we're 1306 00:52:45,060 --> 00:52:40,960 going someplace we've never been before 1307 00:52:47,250 --> 00:52:45,070 so we're primarily interested in what's 1308 00:52:49,200 --> 00:52:47,260 the source of the hydrogen so it could 1309 00:52:53,790 --> 00:52:49,210 been water hydrated minerals adsorbed 1310 00:52:56,010 --> 00:52:53,800 water organics you know who knows but 1311 00:52:57,420 --> 00:52:56,020 the fact that we see a sodium flash wow 1312 00:52:59,280 --> 00:52:57,430 that's really interesting that's telling 1313 00:53:01,860 --> 00:52:59,290 us something about the moon that we have 1314 00:53:03,870 --> 00:53:01,870 to think about you know something about 1315 00:53:07,080 --> 00:53:03,880 this atmosphere around the moon which is 1316 00:53:10,740 --> 00:53:07,090 in part potentially responsible for the 1317 00:53:12,510 --> 00:53:10,750 migration of water so I know there's a 1318 00:53:14,580 --> 00:53:12,520 lot more in this than just the water 1319 00:53:16,950 --> 00:53:14,590 honestly and I think Mike mentioned how 1320 00:53:19,830 --> 00:53:16,960 this this this data is going to keep 1321 00:53:22,530 --> 00:53:19,840 giving for a long time ever since the 1322 00:53:24,030 --> 00:53:22,540 swing by of the moon four months ago we 1323 00:53:26,340 --> 00:53:24,040 took some very unique data sets that 1324 00:53:28,710 --> 00:53:26,350 will be released very soon to the public 1325 00:53:30,900 --> 00:53:28,720 and then this data after it gets through 1326 00:53:35,610 --> 00:53:30,910 quality checks and will be released and 1327 00:53:37,230 --> 00:53:35,620 hopefully in a few months honestly so it 1328 00:53:39,870 --> 00:53:37,240 remains to be seen what's in it just 1329 00:53:43,680 --> 00:53:39,880 don't know yet okay any other questions 1330 00:53:51,220 --> 00:53:48,880 hi can change your times I was wondering 1331 00:53:54,850 --> 00:53:51,230 whether any signs of blooming any 1332 00:53:56,950 --> 00:53:54,860 earth-based observations I know a couple 1333 00:53:58,780 --> 00:53:56,960 of those telescopes said to have 1334 00:54:01,390 --> 00:53:58,790 definitely did not see that cleaned 1335 00:54:03,820 --> 00:54:01,400 including Palomar well I wouldn't say 1336 00:54:05,770 --> 00:54:03,830 definitely for any of them yet because 1337 00:54:07,060 --> 00:54:05,780 it's tony mentioned it's so early and 1338 00:54:09,670 --> 00:54:07,070 the ground-based teams are still 1339 00:54:11,920 --> 00:54:09,680 analyzing their data so we're just 1340 00:54:14,290 --> 00:54:11,930 looking at the very preliminary you know 1341 00:54:16,300 --> 00:54:14,300 images to give a sense of the types of 1342 00:54:17,920 --> 00:54:16,310 data that have been collected but it's 1343 00:54:21,790 --> 00:54:17,930 just too early to tell to make that 1344 00:54:24,100 --> 00:54:21,800 determination okay and follow up I know 1345 00:54:25,960 --> 00:54:24,110 you said most the most important data is 1346 00:54:29,850 --> 00:54:25,970 the spectra but if they're turns out 1347 00:54:35,410 --> 00:54:29,860 there is no plume what do you lose I 1348 00:54:39,400 --> 00:54:35,420 think what you lose is some estimation 1349 00:54:44,110 --> 00:54:39,410 of the total excavation what the total 1350 00:54:47,260 --> 00:54:44,120 excavation mass that said we imaged the 1351 00:54:49,630 --> 00:54:47,270 crater so we actually have some data 1352 00:54:54,100 --> 00:54:49,640 that we honestly counting on to help us 1353 00:54:56,260 --> 00:54:54,110 fill in that hole so we lose some we 1354 00:54:58,870 --> 00:54:56,270 lose you know what we hope to get out of 1355 00:55:01,180 --> 00:54:58,880 the ejecta cloud was an ability to say 1356 00:55:03,820 --> 00:55:01,190 AHA we see this much stuff this much 1357 00:55:05,260 --> 00:55:03,830 dirt and we can somehow relate that to 1358 00:55:07,240 --> 00:55:05,270 how much actually came out of the 1359 00:55:08,620 --> 00:55:07,250 Creator now we're going to if we don't 1360 00:55:10,120 --> 00:55:08,630 see it Jack dear i'm not convinced it's 1361 00:55:12,910 --> 00:55:10,130 not in our data yet i'm not at all 1362 00:55:15,760 --> 00:55:12,920 commands that we've gotta look we've got 1363 00:55:17,770 --> 00:55:15,770 to go back and use a combination of the 1364 00:55:22,270 --> 00:55:17,780 data we have to fill in that missing gap 1365 00:55:24,670 --> 00:55:22,280 if it's if it's in be missing but again 1366 00:55:27,940 --> 00:55:24,680 our primary objectives are what is that 1367 00:55:29,890 --> 00:55:27,950 hydrogen honestly the images didn't 1368 00:55:34,720 --> 00:55:29,900 answer that question the spectroscopy 1369 00:55:37,000 --> 00:55:34,730 answer that question so that's why when 1370 00:55:41,070 --> 00:55:37,010 I saw actually the spectra I was like we 1371 00:55:47,970 --> 00:55:44,670 okay Tony hi this is Mike Swift with the 1372 00:55:49,560 --> 00:55:47,980 San Jose Mercury News can you give us 1373 00:55:51,780 --> 00:55:49,570 some sense of the timetable it's going 1374 00:55:53,730 --> 00:55:51,790 to take you to build the case either for 1375 00:55:57,570 --> 00:55:53,740 or against water is that a matter of 1376 00:55:59,340 --> 00:55:57,580 days weeks months and hypothetically 1377 00:56:02,100 --> 00:55:59,350 those little blips that you saw in the 1378 00:56:08,220 --> 00:56:02,110 spectra what hypothetically could that 1379 00:56:14,750 --> 00:56:08,230 mean now I you're right days weeks 1380 00:56:17,340 --> 00:56:14,760 months yeah that's going to make it yet 1381 00:56:19,740 --> 00:56:17,350 the timetable I've set forward for the 1382 00:56:21,840 --> 00:56:19,750 team and I'm challenge a team but I'll 1383 00:56:23,790 --> 00:56:21,850 cross is unique in every single way I 1384 00:56:25,740 --> 00:56:23,800 mean the way one we kind of lay it all 1385 00:56:27,900 --> 00:56:25,750 out there to swing by return on 1386 00:56:29,700 --> 00:56:27,910 streaming video boy we hope this works 1387 00:56:31,650 --> 00:56:29,710 you know in the same way here it's boy 1388 00:56:34,770 --> 00:56:31,660 we hope this works but the instruments 1389 00:56:37,500 --> 00:56:34,780 the spacecraft it's a real time mission 1390 00:56:42,120 --> 00:56:37,510 we never repeat anything twice I think 1391 00:56:44,030 --> 00:56:42,130 on this mission so we were at two hours 1392 00:56:46,230 --> 00:56:44,040 this is our two hour mark after impact 1393 00:56:49,350 --> 00:56:46,240 then we have a two-day mark that the 1394 00:56:50,820 --> 00:56:49,360 team most the science team is here we're 1395 00:56:53,660 --> 00:56:50,830 going to get together later this 1396 00:56:56,940 --> 00:56:53,670 afternoon tomorrow look at the data 1397 00:57:00,600 --> 00:56:56,950 scratch our heads fight over who gets to 1398 00:57:02,910 --> 00:57:00,610 analyze what and then we go off and we 1399 00:57:05,640 --> 00:57:02,920 meet in two weeks and that two weeks is 1400 00:57:10,010 --> 00:57:05,650 where we hopefully will say we've got 1401 00:57:12,210 --> 00:57:10,020 something for for this particular 1402 00:57:16,230 --> 00:57:12,220 hypothesis or this particular process 1403 00:57:19,680 --> 00:57:16,240 and from that then we hope to make a 1404 00:57:21,780 --> 00:57:19,690 public announcement etc and two in a 1405 00:57:23,730 --> 00:57:21,790 two-month time frame so it's kind of two 1406 00:57:25,260 --> 00:57:23,740 hours two days two weeks two months so 1407 00:57:27,420 --> 00:57:25,270 when what you said what you describe is 1408 00:57:28,920 --> 00:57:27,430 quite accurate we will be making 1409 00:57:31,290 --> 00:57:28,930 presentations at the American 1410 00:57:34,530 --> 00:57:31,300 Geophysical Union and in san francisco 1411 00:57:37,410 --> 00:57:34,540 in december and hopefully there we can 1412 00:57:40,080 --> 00:57:37,420 say something quite definitive what 1413 00:57:42,690 --> 00:57:40,090 those little blips mean I'm just glad 1414 00:57:45,630 --> 00:57:42,700 they're there honestly because that's it 1415 00:57:47,910 --> 00:57:45,640 could have been a flat black line and it 1416 00:57:49,740 --> 00:57:47,920 wasn't and we're not the only one since 1417 00:57:50,880 --> 00:57:49,750 I interesting blips so we just got to go 1418 00:57:53,150 --> 00:57:50,890 back and see what it is it could be 1419 00:57:57,170 --> 00:57:53,160 honestly it could be purely interesting 1420 00:57:58,549 --> 00:57:57,180 I don't think that flash is I am anxious 1421 00:58:00,680 --> 00:57:58,559 to go back and see if I see an o H 1422 00:58:04,039 --> 00:58:00,690 emission line in h2o plus line a sodium 1423 00:58:08,930 --> 00:58:04,049 line whatever so we just gotta get into 1424 00:58:10,700 --> 00:58:08,940 it just haven't met okay we'll take one 1425 00:58:13,760 --> 00:58:10,710 more question here in the audience and 1426 00:58:16,099 --> 00:58:13,770 then we'll take questions over from the 1427 00:58:20,000 --> 00:58:16,109 phone Donald Robertson spaceflight 1428 00:58:21,980 --> 00:58:20,010 London what um how can you have a crater 1429 00:58:23,930 --> 00:58:21,990 and no ejecta if you don't see the 1430 00:58:25,640 --> 00:58:23,940 ejecta what does that tell you and you 1431 00:58:27,890 --> 00:58:25,650 do see a crater well yeah that's a 1432 00:58:30,559 --> 00:58:27,900 that's a great question and I think we 1433 00:58:35,539 --> 00:58:30,569 got a couple of theses and people could 1434 00:58:37,220 --> 00:58:35,549 right here on that so the the process of 1435 00:58:40,520 --> 00:58:37,230 making a crater is pretty complex and 1436 00:58:42,319 --> 00:58:40,530 not necessarily entirely understood we 1437 00:58:45,890 --> 00:58:42,329 have some of the world experts in the 1438 00:58:48,829 --> 00:58:45,900 audience here who are on the team what 1439 00:58:51,140 --> 00:58:48,839 would that mean to me one the ejecta did 1440 00:58:54,620 --> 00:58:51,150 not fly up high enough we hit a slope we 1441 00:58:57,769 --> 00:58:54,630 hit some blocks that Kareem the dejected 1442 00:58:59,269 --> 00:58:57,779 laterally I've we've actually seen this 1443 00:59:00,740 --> 00:58:59,279 work in the other way gotten lucky and 1444 00:59:04,400 --> 00:59:00,750 hit a slope in the right direction and 1445 00:59:07,279 --> 00:59:04,410 Korean the ejecta upward so there's that 1446 00:59:09,740 --> 00:59:07,289 there's some just unfortunately luck 1447 00:59:11,390 --> 00:59:09,750 that that has to come in here to get 1448 00:59:15,170 --> 00:59:11,400 dejected to fly in the direction you 1449 00:59:17,569 --> 00:59:15,180 wanted to fly there is the type of 1450 00:59:21,799 --> 00:59:17,579 material you hit is it at roccos it 1451 00:59:23,059 --> 00:59:21,809 consolidated is it compressible that we 1452 00:59:29,569 --> 00:59:23,069 don't really know there's a part of this 1453 00:59:31,849 --> 00:59:29,579 experiment tells us that there's a the 1454 00:59:33,740 --> 00:59:31,859 composition the material itself how the 1455 00:59:36,559 --> 00:59:33,750 energy coupled to it and how actually 1456 00:59:38,269 --> 00:59:36,569 the energy propagated through the sound 1457 00:59:39,859 --> 00:59:38,279 waves and actually lift the material up 1458 00:59:41,660 --> 00:59:39,869 we just don't know exactly how that 1459 00:59:44,870 --> 00:59:41,670 works necessarily for all the 1460 00:59:46,430 --> 00:59:44,880 possibilities on the moon and there's 1461 00:59:47,839 --> 00:59:46,440 the possibility that the shadow heights 1462 00:59:50,599 --> 00:59:47,849 were deeper than we thought they were 1463 00:59:53,420 --> 00:59:50,609 you know we're basing this on the latest 1464 00:59:54,950 --> 00:59:53,430 and best available data and we just need 1465 00:59:57,799 --> 00:59:54,960 to go back and take a look at all of it 1466 01:00:00,440 --> 00:59:57,809 there's explanations for sure how you 1467 01:00:01,930 --> 01:00:00,450 can have a crater we saw a crater we saw 1468 01:00:03,910 --> 01:00:01,940 a flash so that something had 1469 01:00:05,500 --> 01:00:03,920 in between and we're going to go fine 1470 01:00:06,910 --> 01:00:05,510 and we see it in the spectrometers 1471 01:00:08,470 --> 01:00:06,920 that's what's very you know we do see 1472 01:00:10,300 --> 01:00:08,480 something in the spectrometers it's I 1473 01:00:12,309 --> 01:00:10,310 don't know what it is I'm not gonna say 1474 01:00:14,079 --> 01:00:12,319 it's the ejecta cloud right now but 1475 01:00:15,970 --> 01:00:14,089 something happened in between we just 1476 01:00:19,030 --> 01:00:15,980 got to go back in and with a finer tooth 1477 01:00:21,280 --> 01:00:19,040 comb and if I can just make a quick 1478 01:00:24,339 --> 01:00:21,290 comment what you're seeing here is this 1479 01:00:27,099 --> 01:00:24,349 is what exploration is you know the 1480 01:00:29,500 --> 01:00:27,109 these areas haven't seen the light of 1481 01:00:33,099 --> 01:00:29,510 the Sun for some estimate up to two 1482 01:00:36,670 --> 01:00:33,109 billion years so if we don't have that 1483 01:00:39,609 --> 01:00:36,680 kind of information we make estimates 1484 01:00:41,410 --> 01:00:39,619 and we plan as best we can but you take 1485 01:00:43,240 --> 01:00:41,420 the results of the experiment and you 1486 01:00:45,730 --> 01:00:43,250 move from there and you start to use 1487 01:00:48,819 --> 01:00:45,740 those results to constrain what the 1488 01:00:51,370 --> 01:00:48,829 answer might look like so you're right 1489 01:00:56,079 --> 01:00:51,380 in the middle of it with us um in in 1490 01:00:58,660 --> 01:00:56,089 trying to understand this okay thank you 1491 01:01:02,910 --> 01:00:58,670 very much now we'll take the question 1492 01:01:06,099 --> 01:01:02,920 from Denver igano with USA Today dan 1493 01:01:10,120 --> 01:01:06,109 thanks very very much I have to question 1494 01:01:11,890 --> 01:01:10,130 Oh could you speak a little about more 1495 01:01:14,230 --> 01:01:11,900 of I want you to lose with the flu I'm 1496 01:01:15,910 --> 01:01:14,240 raising into sunlight my understanding 1497 01:01:17,349 --> 01:01:15,920 was there's some cooking of the 1498 01:01:22,300 --> 01:01:17,359 ingredients that would tell you 1499 01:01:24,609 --> 01:01:22,310 something some repeat the last by the 1500 01:01:26,980 --> 01:01:24,619 question this way what it wasn't part of 1501 01:01:28,599 --> 01:01:26,990 the plume uh the intended creating it 1502 01:01:30,339 --> 01:01:28,609 was that it was so sighs above the 1503 01:01:31,690 --> 01:01:30,349 crater wall did the sunlight and you 1504 01:01:33,250 --> 01:01:31,700 would have see some reactions there that 1505 01:01:35,589 --> 01:01:33,260 might give you support well yeah you 1506 01:01:37,240 --> 01:01:35,599 know notionally if for example you have 1507 01:01:39,760 --> 01:01:37,250 cold ejected you want to bring it into 1508 01:01:41,650 --> 01:01:39,770 sunlight one you can see if there's ice 1509 01:01:44,020 --> 01:01:41,660 in the ejecta or you can see if there's 1510 01:01:47,020 --> 01:01:44,030 subliming water you know that's that's 1511 01:01:48,579 --> 01:01:47,030 one of the things you hope for now that 1512 01:01:52,000 --> 01:01:48,589 doesn't mean that didn't happen it means 1513 01:01:55,270 --> 01:01:52,010 maybe it was much fainter more diffuse 1514 01:01:57,370 --> 01:01:55,280 did this gets to you know the earlier 1515 01:01:58,690 --> 01:01:57,380 question about well if you didn't see a 1516 01:02:01,150 --> 01:01:58,700 jekking to south crater was it means 1517 01:02:03,849 --> 01:02:01,160 even just a flight angle of the ejecta 1518 01:02:05,290 --> 01:02:03,859 can make that the cloud less dense but 1519 01:02:07,390 --> 01:02:05,300 you know then what we had thought it was 1520 01:02:11,260 --> 01:02:07,400 going to be or whatever so we just need 1521 01:02:13,599 --> 01:02:11,270 to be careful and one say we just don't 1522 01:02:14,289 --> 01:02:13,609 know right now what what what we saw 1523 01:02:18,459 --> 01:02:14,299 entirely 1524 01:02:20,799 --> 01:02:18,469 but what uh what I don't think you 1525 01:02:23,529 --> 01:02:20,809 necessarily lose any information with 1526 01:02:25,029 --> 01:02:23,539 regards to understanding what it is is 1527 01:02:27,849 --> 01:02:25,039 there it would have been you know 1528 01:02:29,979 --> 01:02:27,859 assuming we had no eject it would have 1529 01:02:32,079 --> 01:02:29,989 been a very nice thing to have but the 1530 01:02:34,449 --> 01:02:32,089 fact that we got good spectroscopic data 1531 01:02:36,219 --> 01:02:34,459 and I mean ejecting cameras we got the 1532 01:02:38,890 --> 01:02:36,229 spectroscopic data and that's what 1533 01:02:41,650 --> 01:02:38,900 really matters so something occurred in 1534 01:02:43,719 --> 01:02:41,660 the sunlight or from the heat from the 1535 01:02:45,699 --> 01:02:43,729 crater the fact that we flew in saw the 1536 01:02:49,689 --> 01:02:45,709 crater and it was school still glowing 1537 01:02:51,819 --> 01:02:49,699 hot means that if there was ice there or 1538 01:02:55,989 --> 01:02:51,829 absorb water or whatever else it was 1539 01:02:58,599 --> 01:02:55,999 subliming so we just go back and take a 1540 01:03:00,400 --> 01:02:58,609 look thanks very much my second question 1541 01:03:02,019 --> 01:03:00,410 was whether you could say anything about 1542 01:03:03,910 --> 01:03:02,029 this mission to the model for future 1543 01:03:05,289 --> 01:03:03,920 mission that a lots been made of this 1544 01:03:07,269 --> 01:03:05,299 being off-the-shelf technology and that 1545 01:03:09,459 --> 01:03:07,279 sort of thing would you be able to do 1546 01:03:12,039 --> 01:03:09,469 something identical to this to explore 1547 01:03:13,900 --> 01:03:12,049 earth asteroid for its contents or it's 1548 01:03:18,309 --> 01:03:13,910 just a special situation they'll promise 1549 01:03:19,779 --> 01:03:18,319 that you will do please yeah this this 1550 01:03:21,880 --> 01:03:19,789 is actually something that is being 1551 01:03:25,989 --> 01:03:21,890 considered this is a really novel 1552 01:03:29,019 --> 01:03:25,999 approach as far as spacecraft complexity 1553 01:03:30,579 --> 01:03:29,029 goes I mean spacecraft can be very 1554 01:03:32,469 --> 01:03:30,589 complicated things and pretty 1555 01:03:34,630 --> 01:03:32,479 unforgiving because once you let go of 1556 01:03:37,839 --> 01:03:34,640 them you can't go back and fix them and 1557 01:03:39,609 --> 01:03:37,849 so keeping your complexity as low as 1558 01:03:42,039 --> 01:03:39,619 possible keeping everything as simple as 1559 01:03:44,289 --> 01:03:42,049 possible helps keep your wrist down and 1560 01:03:46,509 --> 01:03:44,299 I think that's why this mission has been 1561 01:03:49,419 --> 01:03:46,519 so successful in how quickly it turned 1562 01:03:51,669 --> 01:03:49,429 around how quickly we got it up and able 1563 01:03:54,160 --> 01:03:51,679 to be launched and and the mission even 1564 01:03:56,949 --> 01:03:54,170 through some trouble spots was able to 1565 01:04:00,039 --> 01:03:56,959 complete so I think this is a great 1566 01:04:01,719 --> 01:04:00,049 paradigm and I think it is extensible I 1567 01:04:05,339 --> 01:04:01,729 think it could be applied to other 1568 01:04:07,749 --> 01:04:05,349 mission types and so forth absolutely 1569 01:04:10,589 --> 01:04:07,759 okay we're starting to run out of time 1570 01:04:15,880 --> 01:04:10,599 here so we'll take our last two people 1571 01:04:17,799 --> 01:04:15,890 Seth bornstein from 80 thank you for 1572 01:04:21,459 --> 01:04:17,809 doing that's just more ejecta question 1573 01:04:23,349 --> 01:04:21,469 first can you say that it is a fair to 1574 01:04:26,259 --> 01:04:23,359 say well you have absolutely no images 1575 01:04:28,210 --> 01:04:26,269 so far of the ejector visually the 1576 01:04:31,570 --> 01:04:28,220 spectroscopic data is 1577 01:04:33,880 --> 01:04:31,580 confirm the ejecta and can use from mass 1578 01:04:37,089 --> 01:04:33,890 spectra targets drop it data can you say 1579 01:04:38,890 --> 01:04:37,099 how far the ejecta reached or how big a 1580 01:04:40,750 --> 01:04:38,900 plume you had just from that data and 1581 01:04:42,580 --> 01:04:40,760 then can you just say whether you're I 1582 01:04:45,370 --> 01:04:42,590 mean the public was somewhat 1583 01:04:47,290 --> 01:04:45,380 disappointed is my colleague at the LA 1584 01:04:48,970 --> 01:04:47,300 Times that could are you somewhat 1585 01:04:53,970 --> 01:04:48,980 disappointed and surprised by the lack 1586 01:04:59,800 --> 01:04:57,040 the first I'll take the last one first 1587 01:05:03,460 --> 01:04:59,810 and then comment more detail honest it 1588 01:05:05,770 --> 01:05:03,470 on the first question I'm I guess I'm 1589 01:05:08,260 --> 01:05:05,780 not necessarily surprised because I knew 1590 01:05:09,640 --> 01:05:08,270 I would be surprised if that makes any 1591 01:05:11,800 --> 01:05:09,650 sense I knew we were going someplace 1592 01:05:13,780 --> 01:05:11,810 that to expect what you're not going to 1593 01:05:16,270 --> 01:05:13,790 expect and and so that's why we really 1594 01:05:18,070 --> 01:05:16,280 try to build this as robust as possible 1595 01:05:20,470 --> 01:05:18,080 in terms of measuring every possible 1596 01:05:22,330 --> 01:05:20,480 aspect intention in case any one of them 1597 01:05:24,099 --> 01:05:22,340 didn't work like the flash didn't work 1598 01:05:26,109 --> 01:05:24,109 or couldn't see the crater or the 1599 01:05:28,890 --> 01:05:26,119 objective was hard to see I'm not 1600 01:05:31,510 --> 01:05:28,900 convinced we haven't seen the ejecta I 1601 01:05:34,240 --> 01:05:31,520 want to go back to those images and look 1602 01:05:39,070 --> 01:05:34,250 at them carefully what you saw was you 1603 01:05:41,859 --> 01:05:39,080 know about 15-20 minutes of my efforts 1604 01:05:43,839 --> 01:05:41,869 with the images while my team worked to 1605 01:05:45,579 --> 01:05:43,849 other aspects and we're going to work on 1606 01:05:47,440 --> 01:05:45,589 that tip this afternoon and tomorrow so 1607 01:05:50,440 --> 01:05:47,450 stay tuned you know I I certainly hope 1608 01:05:53,740 --> 01:05:50,450 we can dig something out of there that 1609 01:05:55,150 --> 01:05:53,750 that will be telling you know you just 1610 01:05:58,060 --> 01:05:55,160 never know how these things are going to 1611 01:05:59,650 --> 01:05:58,070 go and as we said our emphasis was on 1612 01:06:02,950 --> 01:05:59,660 the spectra that's where the information 1613 01:06:07,359 --> 01:06:02,960 is I'm very hopeful but i'm not going to 1614 01:06:11,950 --> 01:06:07,369 say I'm unequivocally certain that we 1615 01:06:16,750 --> 01:06:11,960 have curtain spectra i can say i am very 1616 01:06:20,440 --> 01:06:16,760 confident we have flash spectra that's a 1617 01:06:23,349 --> 01:06:20,450 certain and and and it looks promising 1618 01:06:27,510 --> 01:06:23,359 beyond that but again i just have to go 1619 01:06:29,510 --> 01:06:27,520 back and do more than a once-over 1620 01:06:32,760 --> 01:06:29,520 with with you know total radiance 1621 01:06:35,190 --> 01:06:32,770 measurements yeah this may sound really 1622 01:06:38,040 --> 01:06:35,200 obvious but this isn't the end this is 1623 01:06:41,940 --> 01:06:38,050 the beginning there's an awful lot of 1624 01:06:44,280 --> 01:06:41,950 work that still needs to be done and for 1625 01:06:45,600 --> 01:06:44,290 those of you who've conducted 1626 01:06:48,900 --> 01:06:45,610 experiments in the past to have 1627 01:06:51,360 --> 01:06:48,910 something absolutely certain right after 1628 01:06:54,270 --> 01:06:51,370 you're done with the experiment is not 1629 01:06:55,830 --> 01:06:54,280 the way most scientists have have 1630 01:06:59,040 --> 01:06:55,840 experienced the results of their 1631 01:07:00,510 --> 01:06:59,050 experiments if there's anything I would 1632 01:07:02,700 --> 01:07:00,520 add to that the one thing I was 1633 01:07:05,790 --> 01:07:02,710 surprised by was how quick four minutes 1634 01:07:08,040 --> 01:07:05,800 goes by that's this that was the one 1635 01:07:10,050 --> 01:07:08,050 thing I really noticed was ok here's 1636 01:07:11,580 --> 01:07:10,060 flash we're halfway through curtain wait 1637 01:07:14,640 --> 01:07:11,590 wait wait what happened and then clear 1638 01:07:15,960 --> 01:07:14,650 crater oh there it goes Wow yeah get 1639 01:07:19,380 --> 01:07:15,970 ready for the press conference you know 1640 01:07:22,290 --> 01:07:19,390 that's basically how it went ok we have 1641 01:07:24,390 --> 01:07:22,300 only a couple more minutes left we'll 1642 01:07:28,140 --> 01:07:24,400 take our last question from our Lee 1643 01:07:32,280 --> 01:07:28,150 Irene Klotz from this Irene Klotz thank 1644 01:07:35,040 --> 01:07:32,290 you very much yet can hear me yes thank 1645 01:07:37,230 --> 01:07:35,050 you um congratulations first of all I 1646 01:07:38,970 --> 01:07:37,240 have two questions on the first I'm 1647 01:07:40,680 --> 01:07:38,980 afraid I was going to display my 1648 01:07:44,070 --> 01:07:40,690 scientific ignorance but could you 1649 01:07:45,630 --> 01:07:44,080 explain why this sodium measurement 1650 01:07:46,950 --> 01:07:45,640 popped out to the point where you're 1651 01:07:50,670 --> 01:07:46,960 even mentioning it it's a press 1652 01:07:53,670 --> 01:07:50,680 conference I can comment down and 1653 01:07:56,010 --> 01:07:53,680 possibly genuine and Mike could to the 1654 01:07:58,620 --> 01:07:56,020 we don't understand right now how the 1655 01:08:01,200 --> 01:07:58,630 lunar exosphere works and the exosphere 1656 01:08:05,580 --> 01:08:01,210 is the atmosphere that very tenuous 1657 01:08:07,230 --> 01:08:05,590 atmosphere around the moon it is there's 1658 01:08:08,850 --> 01:08:07,240 a variety of theories and the most 1659 01:08:11,390 --> 01:08:08,860 recently heard about the the 1660 01:08:13,500 --> 01:08:11,400 observations of very small amounts of 1661 01:08:16,860 --> 01:08:13,510 hydroxyls and waters near the surface 1662 01:08:20,190 --> 01:08:16,870 and sunlight how that might move around 1663 01:08:23,160 --> 01:08:20,200 is through this atmosphere the fact that 1664 01:08:25,079 --> 01:08:23,170 we saw sodium line means that something 1665 01:08:27,450 --> 01:08:25,089 was thermalized down in the crater when 1666 01:08:29,730 --> 01:08:27,460 we hit it temperatures got hot enough 1667 01:08:31,410 --> 01:08:29,740 reacted with the surface perhaps or 1668 01:08:35,410 --> 01:08:31,420 reacted with the atmosphere ambient 1669 01:08:37,849 --> 01:08:35,420 atmosphere enough to excite sodium atoms 1670 01:08:40,760 --> 01:08:37,859 sodium atoms exist naturally in the 1671 01:08:43,340 --> 01:08:40,770 lunar atmosphere why an impact like this 1672 01:08:44,479 --> 01:08:43,350 would excite it is a good question and 1673 01:08:47,419 --> 01:08:44,489 that's something we're really going to 1674 01:08:49,280 --> 01:08:47,429 follow up on sodium is easy to observe 1675 01:08:54,349 --> 01:08:49,290 from Earth it's a very strong line in 1676 01:08:55,910 --> 01:08:54,359 the visible we on HST and on our 1677 01:08:57,919 --> 01:08:55,920 shipping spacecraft can see a variety of 1678 01:08:59,809 --> 01:08:57,929 other emission lines that are more 1679 01:09:01,849 --> 01:08:59,819 indicative of other interesting things 1680 01:09:03,320 --> 01:09:01,859 like water and so that's you know we'll 1681 01:09:05,390 --> 01:09:03,330 have to go back and see what we see in 1682 01:09:07,309 --> 01:09:05,400 there so the fact we saw a sodium line 1683 01:09:09,769 --> 01:09:07,319 is exciting because it means we did 1684 01:09:11,539 --> 01:09:09,779 excite something in the crater and it 1685 01:09:15,979 --> 01:09:11,549 did express itself such that we can 1686 01:09:17,809 --> 01:09:15,989 measure it okay thank you very much I'd 1687 01:09:19,820 --> 01:09:17,819 like to thank the panelists for all 1688 01:09:21,559 --> 01:09:19,830 their hard work and I know you guys are 1689 01:09:25,729 --> 01:09:21,569 in to get some sleep and then look at 1690 01:09:27,019 --> 01:09:25,739 this data with new eyes rested eyes okay 1691 01:09:29,959 --> 01:09:27,029 I know everyone here is going to be 1692 01:09:31,970 --> 01:09:29,969 waiting for these results any new 1693 01:09:36,260 --> 01:09:31,980 results we will have will be posted on 1694 01:09:39,410 --> 01:09:36,270 the El cross website www nasa gov / l 1695 01:09:42,950 --> 01:09:39,420 cross and with that thank you very much
