--> 00:00:37,320 to interact with NASA scientists and 5 00:00:41,750 --> 00:00:38,940 have your questions answered in real 6 00:00:43,670 --> 00:00:41,760 time I'm your host joyung and tonight we 7 00:00:46,549 --> 00:00:43,680 are live at NASA's Goddard space flight 8 00:00:49,069 --> 00:00:46,559 center as the total lunar eclipse is 9 00:00:51,290 --> 00:00:49,079 nearing totality so it's a little bit 10 00:00:52,670 --> 00:00:51,300 overcast here right now but luckily 11 00:00:54,410 --> 00:00:52,680 we're going to be taking you to 12 00:00:56,750 --> 00:00:54,420 different locations with clear skies 13 00:00:58,729 --> 00:00:56,760 throughout the show so if you have any 14 00:01:01,130 --> 00:00:58,739 questions at all about the total lunar 15 00:01:03,410 --> 00:01:01,140 eclipse all by NASA is heading back to 16 00:01:05,810 --> 00:01:03,420 the Moon send your questions in using 17 00:01:07,969 --> 00:01:05,820 the hashtag asknassa or wherever you're 18 00:01:10,490 --> 00:01:07,979 watching the show today and as you can 19 00:01:12,530 --> 00:01:10,500 see we will have a constant live feed of 20 00:01:14,090 --> 00:01:12,540 the lunar eclipse so thank you so much 21 00:01:16,490 --> 00:01:14,100 to our friends at time and date for 22 00:01:18,230 --> 00:01:16,500 providing that feed so as you can see 23 00:01:20,870 --> 00:01:18,240 there's a lot of excitement in the air 24 00:01:22,609 --> 00:01:20,880 and we have a lot in store for you as we 25 00:01:24,530 --> 00:01:22,619 track the lunar eclipse from North and 26 00:01:26,450 --> 00:01:24,540 South America and parts of Europe as 27 00:01:28,609 --> 00:01:26,460 well we have NASA scientists answering 28 00:01:30,530 --> 00:01:28,619 your questions and we also have feeds of 29 00:01:32,810 --> 00:01:30,540 tell us Scopes dotted all around the 30 00:01:34,969 --> 00:01:32,820 world that are fixated on tonight's 31 00:01:37,190 --> 00:01:34,979 Celestial event and there's a chance 32 00:01:39,830 --> 00:01:37,200 that you too can see the lunar eclipse 33 00:01:41,810 --> 00:01:39,840 as well so if you do snap a photo and 34 00:01:42,889 --> 00:01:41,820 start with us on social media or 35 00:01:44,569 --> 00:01:42,899 wherever you're watching tonight's 36 00:01:47,270 --> 00:01:44,579 episode 37 00:01:48,950 --> 00:01:47,280 um so there's yeah 38 00:01:50,450 --> 00:01:48,960 uh there's a lot to talk about and we 39 00:01:52,910 --> 00:01:50,460 have a lot of questions coming in online 40 00:01:55,429 --> 00:01:52,920 but first let's go over to my co-host 41 00:01:57,469 --> 00:01:55,439 James traily who can tell us where we 42 00:01:59,810 --> 00:01:57,479 are on the eclipse right now and what's 43 00:02:01,910 --> 00:01:59,820 in store for us in tonight's total lunar 44 00:02:04,010 --> 00:02:01,920 eclipse hey James how's it going over 45 00:02:05,389 --> 00:02:04,020 there good there are some extreme micro 46 00:02:07,010 --> 00:02:05,399 climates out there but unfortunately 47 00:02:08,389 --> 00:02:07,020 just a couple feet away from you and the 48 00:02:11,390 --> 00:02:08,399 other side of the building it's also 49 00:02:13,070 --> 00:02:11,400 overcast and rainy so not holding out 50 00:02:14,690 --> 00:02:13,080 you know for a good view from here 51 00:02:16,130 --> 00:02:14,700 release but we're tracking it all across 52 00:02:18,290 --> 00:02:16,140 the world the view behind me right here 53 00:02:19,729 --> 00:02:18,300 is from Cartersville Georgia where 54 00:02:21,350 --> 00:02:19,739 there's a little bit of cloud cover but 55 00:02:23,270 --> 00:02:21,360 we've got a really nice view coming into 56 00:02:24,410 --> 00:02:23,280 Focus tracking this from around the 57 00:02:27,050 --> 00:02:24,420 world as well we got some feeds from 58 00:02:28,490 --> 00:02:27,060 Morocco all over Spain and it's just 59 00:02:30,949 --> 00:02:28,500 going to be a phenomenal show to view 60 00:02:32,630 --> 00:02:30,959 from there so is this your first ever 61 00:02:37,430 --> 00:02:32,640 eclipse 62 00:02:39,890 --> 00:02:37,440 in 2019 in uh Mexico City actually and 63 00:02:42,650 --> 00:02:39,900 it was an amazing experience what about 64 00:02:44,150 --> 00:02:42,660 yourself it's been I think at least a 65 00:02:45,229 --> 00:02:44,160 decade for me it's been a really long 66 00:02:47,210 --> 00:02:45,239 time and I guess I'm gonna have to keep 67 00:02:48,830 --> 00:02:47,220 waiting as well but live vicariously 68 00:02:51,530 --> 00:02:48,840 through the amazing fees that we've got 69 00:02:53,570 --> 00:02:51,540 out here as well so how many feeds do we 70 00:02:55,309 --> 00:02:53,580 have tonight yeah quite a few I think 71 00:02:56,330 --> 00:02:55,319 I'm tracking at least eight here so far 72 00:02:58,130 --> 00:02:56,340 there's some that are kind of cycling 73 00:02:59,930 --> 00:02:58,140 through for me as well too from parts of 74 00:03:01,490 --> 00:02:59,940 the west coast of the United States out 75 00:03:03,589 --> 00:03:01,500 in La we've got a really cool view from 76 00:03:05,089 --> 00:03:03,599 Ontario Canada as well a lot of places 77 00:03:06,290 --> 00:03:05,099 are fighting with a little bit of cloud 78 00:03:08,210 --> 00:03:06,300 cover so we'll kind of see how that 79 00:03:09,410 --> 00:03:08,220 develops over the night as well one of 80 00:03:11,210 --> 00:03:09,420 the views I'm tracking as well is from 81 00:03:12,589 --> 00:03:11,220 Rome Italy where as the night goes on 82 00:03:14,630 --> 00:03:12,599 the moon is going to get lower and lower 83 00:03:16,009 --> 00:03:14,640 and the Horizon we might even get a view 84 00:03:18,170 --> 00:03:16,019 of the Coliseum as well which would be 85 00:03:19,309 --> 00:03:18,180 fantastic as well but at least for right 86 00:03:22,430 --> 00:03:19,319 now let's learn a little bit more about 87 00:03:24,229 --> 00:03:22,440 the science behind a lunar eclipse 88 00:03:25,729 --> 00:03:24,239 if you looked at the Moon over the 89 00:03:26,990 --> 00:03:25,739 course of a few weeks you'd probably 90 00:03:29,570 --> 00:03:27,000 notice that it looks slightly different 91 00:03:31,250 --> 00:03:29,580 every day the change in its shadow is 92 00:03:33,229 --> 00:03:31,260 based on where the Moon is in its orbit 93 00:03:35,030 --> 00:03:33,239 we call this cycle the phases of the 94 00:03:37,490 --> 00:03:35,040 moon and it occurs roughly once a month 95 00:03:39,830 --> 00:03:37,500 at least twice a year however something 96 00:03:41,089 --> 00:03:39,840 quite different happens the moon passes 97 00:03:43,190 --> 00:03:41,099 through the shadow cast by the Earth 98 00:03:45,229 --> 00:03:43,200 causing it to look extremely unusual for 99 00:03:47,149 --> 00:03:45,239 a short period of time from the earth 100 00:03:48,830 --> 00:03:47,159 the moon will appear to darken and turn 101 00:03:50,990 --> 00:03:48,840 a deep red before eventually returning 102 00:03:52,850 --> 00:03:51,000 to normal this is called a lunar eclipse 103 00:03:54,470 --> 00:03:52,860 if we were to look at what happens from 104 00:03:56,690 --> 00:03:54,480 space during an eclipse it would go 105 00:03:57,710 --> 00:03:56,700 something like this first the moon 106 00:03:59,509 --> 00:03:57,720 passes through What's called the 107 00:04:01,970 --> 00:03:59,519 penumbra where the Sun's light is only 108 00:04:03,649 --> 00:04:01,980 partially obscured this results in only 109 00:04:05,449 --> 00:04:03,659 a slight darkening of the Moon 110 00:04:07,070 --> 00:04:05,459 as the moon continues along its path 111 00:04:08,509 --> 00:04:07,080 however it enters What's called the 112 00:04:10,850 --> 00:04:08,519 Umbra where all direct light from the 113 00:04:12,710 --> 00:04:10,860 sun is blocked but if the Sun is blocked 114 00:04:14,390 --> 00:04:12,720 why does the moon turn red 115 00:04:16,069 --> 00:04:14,400 when light from the sun goes by the side 116 00:04:17,990 --> 00:04:16,079 of the earth it passes through a long 117 00:04:19,789 --> 00:04:18,000 and thick layer of Earth's atmosphere 118 00:04:22,069 --> 00:04:19,799 shorter wavelengths of sunlight like 119 00:04:23,450 --> 00:04:22,079 blue are scattered by the atmosphere so 120 00:04:25,010 --> 00:04:23,460 by the time the light has finished its 121 00:04:27,650 --> 00:04:25,020 trip to the moon more of the longer 122 00:04:29,150 --> 00:04:27,660 wavelengths like red are left over on 123 00:04:30,650 --> 00:04:29,160 the earth the same thing happens at 124 00:04:32,990 --> 00:04:30,660 Sunset as the ground you stand on 125 00:04:34,730 --> 00:04:33,000 gradually passes in tonight as the 126 00:04:36,770 --> 00:04:34,740 eclipse ends the moon leaves the Umbra 127 00:04:38,450 --> 00:04:36,780 returns to its normal color and then 128 00:04:41,210 --> 00:04:38,460 leaves the pen number of brightening and 129 00:04:42,650 --> 00:04:41,220 resuming its original cycle overall the 130 00:04:44,330 --> 00:04:42,660 whole process lasts only from a few 131 00:04:46,610 --> 00:04:44,340 minutes to a few hours so you'll have to 132 00:04:47,749 --> 00:04:46,620 be quick if you want to see it but as 133 00:04:49,430 --> 00:04:47,759 long as you're willing to stay awake 134 00:04:52,370 --> 00:04:49,440 you'll catch the moon as you won't see 135 00:04:56,330 --> 00:04:54,170 so right now I'm joined by science 136 00:04:58,370 --> 00:04:56,340 visualizer and our telescope Guru for 137 00:04:59,629 --> 00:04:58,380 tonight's events Ernie Wright hi James 138 00:05:01,129 --> 00:04:59,639 Ernie thanks so much for joining us uh 139 00:05:02,510 --> 00:05:01,139 it's a pleasure to be here it's a little 140 00:05:03,710 --> 00:05:02,520 bit of a cloudy night but we're still 141 00:05:05,029 --> 00:05:03,720 you know tracking this from across the 142 00:05:06,710 --> 00:05:05,039 world here right now we can actually see 143 00:05:08,210 --> 00:05:06,720 a shadow starting to creep a little bit 144 00:05:09,770 --> 00:05:08,220 across the moon can you tell us where we 145 00:05:11,090 --> 00:05:09,780 are right now in the process right I 146 00:05:13,730 --> 00:05:11,100 mean we're a little bit more than 50 147 00:05:16,129 --> 00:05:13,740 covered in the partial phase and this is 148 00:05:17,930 --> 00:05:16,139 where the Umbra is starting to track 149 00:05:20,510 --> 00:05:17,940 across the moon 150 00:05:22,249 --> 00:05:20,520 um in this view it's a little bit dark a 151 00:05:25,129 --> 00:05:22,259 little bit farther out because of the 152 00:05:26,990 --> 00:05:25,139 exposure that they're using um but over 153 00:05:29,450 --> 00:05:27,000 the next half hour or so we should 154 00:05:32,029 --> 00:05:29,460 expect this Darkness to completely 155 00:05:33,890 --> 00:05:32,039 spread across the moon uh and then when 156 00:05:36,290 --> 00:05:33,900 they change the exposure because the 157 00:05:38,150 --> 00:05:36,300 moon's so dim during totality hopefully 158 00:05:39,529 --> 00:05:38,160 we'll see some red color there too very 159 00:05:41,029 --> 00:05:39,539 excited about that and if you're keeping 160 00:05:42,529 --> 00:05:41,039 score from home and you want to sync up 161 00:05:43,670 --> 00:05:42,539 your events you're outside at the right 162 00:05:44,930 --> 00:05:43,680 moment there's a good chance that you 163 00:05:46,550 --> 00:05:44,940 can capture this from your own backyard 164 00:05:47,810 --> 00:05:46,560 so we want you out there sharing your 165 00:05:48,950 --> 00:05:47,820 picks with us as well we've got the 166 00:05:50,270 --> 00:05:48,960 schedule up here could you just kind of 167 00:05:53,749 --> 00:05:50,280 walk us through some of the highlights 168 00:05:55,430 --> 00:05:53,759 right so um before we came on even 169 00:05:57,890 --> 00:05:55,440 um the partial began and that's the 170 00:05:59,390 --> 00:05:57,900 point where the Umbra is starting to 171 00:06:01,370 --> 00:05:59,400 cover the moon 172 00:06:04,010 --> 00:06:01,380 um about halfway through our program at 173 00:06:06,230 --> 00:06:04,020 11 29 uh totality will begin and that's 174 00:06:07,969 --> 00:06:06,240 when the moon all the brightness will 175 00:06:11,590 --> 00:06:07,979 stop dazzling your eyes and you can see 176 00:06:15,290 --> 00:06:11,600 sort of that dark red color at 11 29 177 00:06:17,510 --> 00:06:15,300 maximum eclipse this is when the moon is 178 00:06:19,070 --> 00:06:17,520 in the middle of the shadow in the 179 00:06:20,809 --> 00:06:19,080 deepest part of the shadow that occurs 180 00:06:24,650 --> 00:06:20,819 about 10 minutes after we're done here 181 00:06:27,350 --> 00:06:24,660 at 12 11 Eastern and the eclipse 182 00:06:29,450 --> 00:06:27,360 continues for another 45 minutes or so 183 00:06:31,129 --> 00:06:29,460 yeah so it's a longer one 85 minutes or 184 00:06:32,330 --> 00:06:31,139 so this is not usually the case usually 185 00:06:33,650 --> 00:06:32,340 they're pretty short so you got some 186 00:06:35,510 --> 00:06:33,660 time to grab a coffee get your camera 187 00:06:36,770 --> 00:06:35,520 set up you know why is why is this one 188 00:06:38,390 --> 00:06:36,780 different I guess from the rest in terms 189 00:06:39,469 --> 00:06:38,400 of length uh it has a lot to do with 190 00:06:41,629 --> 00:06:39,479 whether or not it's going through the 191 00:06:44,450 --> 00:06:41,639 middle of the Shadow or kind of skimming 192 00:06:47,510 --> 00:06:44,460 along the edge this eclipse is in the 193 00:06:50,150 --> 00:06:47,520 top 25 percent of eclipses for duration 194 00:06:51,770 --> 00:06:50,160 so we're pretty close to the middle it 195 00:06:53,689 --> 00:06:51,780 gives everybody lots of chances to go 196 00:06:55,730 --> 00:06:53,699 outside if it's cloudy where you are 197 00:06:57,890 --> 00:06:55,740 right now wait a couple of minutes and 198 00:06:59,510 --> 00:06:57,900 try again yes we're just tracking this 199 00:07:00,710 --> 00:06:59,520 now the conditions are changing so 200 00:07:02,330 --> 00:07:00,720 quickly the cloud cover is kind of 201 00:07:03,950 --> 00:07:02,340 moving over and as I mentioned we really 202 00:07:05,990 --> 00:07:03,960 do want you to capture this moment for 203 00:07:07,309 --> 00:07:06,000 us as well from your own backyard what 204 00:07:08,689 --> 00:07:07,319 are some tips for people to get that 205 00:07:09,950 --> 00:07:08,699 Best Shot you know with whatever camera 206 00:07:12,890 --> 00:07:09,960 they're using you know even their cell 207 00:07:14,270 --> 00:07:12,900 phone right I mean for for one thing it 208 00:07:15,830 --> 00:07:14,280 should be pointed out that we don't need 209 00:07:17,930 --> 00:07:15,840 any special equipment to see it you can 210 00:07:19,730 --> 00:07:17,940 go outside with your naked eye and you 211 00:07:22,010 --> 00:07:19,740 can also see it with binoculars but if 212 00:07:23,890 --> 00:07:22,020 you want to take a photograph you'll 213 00:07:26,510 --> 00:07:23,900 need longer exposure 214 00:07:28,730 --> 00:07:26,520 and you'll want to probably set your 215 00:07:29,990 --> 00:07:28,740 camera not to night mode because if you 216 00:07:31,850 --> 00:07:30,000 set it to night mode it will try to 217 00:07:33,890 --> 00:07:31,860 brighten everything and you're only 218 00:07:36,290 --> 00:07:33,900 trying to take a picture of the Moon if 219 00:07:38,809 --> 00:07:36,300 you're able to zoom you should do that 220 00:07:40,550 --> 00:07:38,819 the Moon is surprisingly small in these 221 00:07:42,170 --> 00:07:40,560 pictures so if you just take a regular 222 00:07:44,330 --> 00:07:42,180 photograph you'll get three pixels of 223 00:07:46,189 --> 00:07:44,340 moon and lots of dark sky 224 00:07:47,930 --> 00:07:46,199 so right now you have your telescope 225 00:07:50,089 --> 00:07:47,940 with us which is getting a great shot of 226 00:07:51,350 --> 00:07:50,099 the studio lights but you know what is 227 00:07:52,430 --> 00:07:51,360 it actually what would it be doing out 228 00:07:54,950 --> 00:07:52,440 in the field if you're actually having 229 00:07:57,350 --> 00:07:54,960 out there right and I brought this in um 230 00:08:00,770 --> 00:07:57,360 so that if we had clear skies we could 231 00:08:03,350 --> 00:08:00,780 actually get a feed from here but this 232 00:08:05,689 --> 00:08:03,360 is just a three inch refractor there are 233 00:08:07,790 --> 00:08:05,699 two basic kinds of telescope a refractor 234 00:08:11,029 --> 00:08:07,800 has a big lens for Gathering light and a 235 00:08:13,490 --> 00:08:11,039 reflector has a big mirror and then I've 236 00:08:17,390 --> 00:08:13,500 attached to the telescope just a regular 237 00:08:19,909 --> 00:08:17,400 DSLR and there's a special bit that 238 00:08:21,830 --> 00:08:19,919 mates them together but this allows the 239 00:08:23,570 --> 00:08:21,840 camera to look through the telescope as 240 00:08:25,850 --> 00:08:23,580 if the telescope were a big telephoto 241 00:08:28,249 --> 00:08:25,860 lens and 242 00:08:30,950 --> 00:08:28,259 what we were planning to do if we had 243 00:08:34,370 --> 00:08:30,960 clear skies was use the Live View mode 244 00:08:37,310 --> 00:08:34,380 on the camera and the camera has HDMI 245 00:08:39,230 --> 00:08:37,320 out and so if you had a crowd and you 246 00:08:41,449 --> 00:08:39,240 didn't want to line them all up and look 247 00:08:43,909 --> 00:08:41,459 through it individually you could put a 248 00:08:45,530 --> 00:08:43,919 TV right next to the telescope and and 249 00:08:47,329 --> 00:08:45,540 everybody could see it simultaneously 250 00:08:48,710 --> 00:08:47,339 just like we're looking at it here yeah 251 00:08:50,030 --> 00:08:48,720 and stuff is really starting to move a 252 00:08:51,350 --> 00:08:50,040 little bit more here now even since we 253 00:08:52,490 --> 00:08:51,360 started talking it seems like there's a 254 00:08:56,329 --> 00:08:52,500 little bit more coverage as well too 255 00:08:58,370 --> 00:08:56,339 yeah um and in fact as time goes on uh 256 00:09:01,490 --> 00:08:58,380 from minute to minute you should be able 257 00:09:03,590 --> 00:09:01,500 to see some changes in the shadow it's 258 00:09:06,889 --> 00:09:03,600 going to move very quickly particularly 259 00:09:08,269 --> 00:09:06,899 when we get close to 11 29 you know the 260 00:09:10,550 --> 00:09:08,279 last little bit of bright moon will be 261 00:09:12,170 --> 00:09:10,560 there and as you're watching it you can 262 00:09:14,030 --> 00:09:12,180 see it being covered up which is pretty 263 00:09:15,530 --> 00:09:14,040 cool what can we expect some of the kind 264 00:09:16,790 --> 00:09:15,540 of reddish color to start creeping in 265 00:09:20,210 --> 00:09:16,800 here as well 266 00:09:21,829 --> 00:09:20,220 um almost before totality starts what 267 00:09:23,210 --> 00:09:21,839 you really need to do is kind of get rid 268 00:09:25,490 --> 00:09:23,220 of all that very bright moon because 269 00:09:28,730 --> 00:09:25,500 that sort of dazzling your eye 270 00:09:31,790 --> 00:09:28,740 um this is thousands of times dimmer but 271 00:09:34,310 --> 00:09:31,800 once you get into totality your eye will 272 00:09:36,290 --> 00:09:34,320 adjust you know your eye has this sort 273 00:09:38,329 --> 00:09:36,300 of automatic exposure control and you'll 274 00:09:40,550 --> 00:09:38,339 be able to see that red color amazing 275 00:09:42,889 --> 00:09:40,560 and what is the next one as well next 276 00:09:45,230 --> 00:09:42,899 lunar eclipse here from November so 277 00:09:47,030 --> 00:09:45,240 anybody who's missing out 278 00:09:48,650 --> 00:09:47,040 um you know six months from now we'll 279 00:09:50,030 --> 00:09:48,660 have another one to look forward to 280 00:09:52,130 --> 00:09:50,040 plenty of time for this one tonight 281 00:09:53,930 --> 00:09:52,140 still too like we said 85 minutes for 282 00:09:55,190 --> 00:09:53,940 you to be able to view this one so a 283 00:09:56,449 --> 00:09:55,200 really good window for you to get you 284 00:09:57,710 --> 00:09:56,459 know nice coffee it's a little bit late 285 00:09:59,509 --> 00:09:57,720 here maybe bundle up a little bit if 286 00:10:00,949 --> 00:09:59,519 it's cold where you are but in the 287 00:10:02,569 --> 00:10:00,959 meantime I understand that Joy has some 288 00:10:04,550 --> 00:10:02,579 members of the Artemis program with her 289 00:10:06,949 --> 00:10:04,560 to talk a bit more about our next 290 00:10:10,490 --> 00:10:06,959 mission to the Moon 291 00:10:12,889 --> 00:10:10,500 hi yes so Earth's moon is the only place 292 00:10:15,769 --> 00:10:12,899 beyond Earth that humans have set foot 293 00:10:17,690 --> 00:10:15,779 on and with NASA's Artemis program we're 294 00:10:19,370 --> 00:10:17,700 planning to take the first woman a first 295 00:10:21,470 --> 00:10:19,380 person of color back to the lunar 296 00:10:24,110 --> 00:10:21,480 surface so to tell us more about that 297 00:10:26,630 --> 00:10:24,120 I'm joined by two with two NASA experts 298 00:10:29,090 --> 00:10:26,640 uh Dr Ryan Watkins who is a program 299 00:10:31,370 --> 00:10:29,100 scientist at NASA headquarters and Dr 300 00:10:33,710 --> 00:10:31,380 Vishnu vishwanathan who is a research 301 00:10:35,449 --> 00:10:33,720 scientist at Nasa Goddard thank you both 302 00:10:37,790 --> 00:10:35,459 so much for joining us today thanks for 303 00:10:39,290 --> 00:10:37,800 having us yeah thanks so can you tell us 304 00:10:41,810 --> 00:10:39,300 a little bit about your roles and what 305 00:10:43,610 --> 00:10:41,820 you do at NASA yeah I'll just start off 306 00:10:45,889 --> 00:10:43,620 by saying it's a very exciting time to 307 00:10:48,050 --> 00:10:45,899 be a lunar scientist at Nasa so at 308 00:10:49,970 --> 00:10:48,060 headquarters um in my office we manage 309 00:10:53,449 --> 00:10:49,980 the lunar Discovery and exploration 310 00:10:55,069 --> 00:10:53,459 program and so under this program Falls 311 00:10:57,590 --> 00:10:55,079 um the various programs that are sending 312 00:10:59,569 --> 00:10:57,600 scientific and Technology development 313 00:11:01,550 --> 00:10:59,579 instruments to the Moon via commercial 314 00:11:03,530 --> 00:11:01,560 Partners as well as on various 315 00:11:04,850 --> 00:11:03,540 International missions we also do all 316 00:11:08,389 --> 00:11:04,860 the integration of Artemis science 317 00:11:10,130 --> 00:11:08,399 within NASA's directorates and yeah so 318 00:11:11,930 --> 00:11:10,140 for my role specifically one of the 319 00:11:13,670 --> 00:11:11,940 things I do is just make sure that our 320 00:11:14,990 --> 00:11:13,680 scientific instruments can meet their 321 00:11:17,090 --> 00:11:15,000 science objectives and have everything 322 00:11:18,829 --> 00:11:17,100 they need to do that it's one of many 323 00:11:20,210 --> 00:11:18,839 many things we do but yeah so getting 324 00:11:22,550 --> 00:11:20,220 science instruments to the moon and 325 00:11:25,550 --> 00:11:22,560 Artemis is a large part of what we do 326 00:11:28,670 --> 00:11:25,560 hey um I'm a research scientist here at 327 00:11:31,130 --> 00:11:28,680 Nasa got it and I primarily use 328 00:11:32,810 --> 00:11:31,140 um like the data sets that are obtained 329 00:11:34,970 --> 00:11:32,820 from Sonic scientific instruments that 330 00:11:36,230 --> 00:11:34,980 we have sent to space primarily to 331 00:11:38,509 --> 00:11:36,240 understand 332 00:11:40,250 --> 00:11:38,519 um the interior structure of planetary 333 00:11:42,530 --> 00:11:40,260 bodies especially the moon and other 334 00:11:46,370 --> 00:11:42,540 planetary bodies as well to put together 335 00:11:49,250 --> 00:11:46,380 a puzzle regarding uh you know how 336 00:11:51,350 --> 00:11:49,260 regarding the evolution and formation of 337 00:11:54,530 --> 00:11:51,360 the solar system in general uh you know 338 00:11:57,590 --> 00:11:54,540 I asked several questions like uh uh 339 00:12:00,170 --> 00:11:57,600 like you know how is uh the moon like 340 00:12:02,030 --> 00:12:00,180 was the moon always uh how it is as we 341 00:12:03,829 --> 00:12:02,040 see it in the sky today or was it 342 00:12:06,590 --> 00:12:03,839 oriented in a different manner compared 343 00:12:08,210 --> 00:12:06,600 to you know several billion years ago or 344 00:12:10,310 --> 00:12:08,220 you know like you know does it have a 345 00:12:13,910 --> 00:12:10,320 solid inner core within it like like we 346 00:12:15,889 --> 00:12:13,920 know for the Earth and um so I I'm 347 00:12:18,530 --> 00:12:15,899 facilitated by several data sets that 348 00:12:21,110 --> 00:12:18,540 we've collected such as the Luna laser 349 00:12:25,310 --> 00:12:21,120 ranging data where we fire lasers to 350 00:12:27,350 --> 00:12:25,320 these mirrors that were left over on the 351 00:12:30,470 --> 00:12:27,360 um you know the lunar surface the new 352 00:12:33,590 --> 00:12:30,480 the lunar near Side by our astronauts 353 00:12:35,870 --> 00:12:33,600 and some of the Rovers and 354 00:12:37,310 --> 00:12:35,880 um as well as the gravity field of the 355 00:12:40,610 --> 00:12:37,320 Moon that was mapped in high resolution 356 00:12:43,449 --> 00:12:40,620 by um in the NASA Grail Mission as well 357 00:12:46,310 --> 00:12:43,459 as lunar topography data for example 358 00:12:49,310 --> 00:12:46,320 that's obtained from the laser ultimate 359 00:12:52,670 --> 00:12:49,320 on the the lro spacecraft which is now 360 00:12:54,410 --> 00:12:52,680 in orbit for like what 13 years now so 361 00:12:56,210 --> 00:12:54,420 yeah this is just a great time as she 362 00:12:58,670 --> 00:12:56,220 said to be a lunar scientist and I'm 363 00:13:00,829 --> 00:12:58,680 really excited to be here 364 00:13:02,389 --> 00:13:00,839 so can we talk a bit about what NASA's 365 00:13:04,069 --> 00:13:02,399 plans are for back so we're going back 366 00:13:07,009 --> 00:13:04,079 to the moon so we're taking science 367 00:13:08,210 --> 00:13:07,019 instruments a river and then humans yeah 368 00:13:09,710 --> 00:13:08,220 so we're actually doing a lot to get 369 00:13:11,150 --> 00:13:09,720 ready to go back to the Moon right now 370 00:13:14,210 --> 00:13:11,160 um like you said one of the first things 371 00:13:15,710 --> 00:13:14,220 we're doing um besides lro is is sending 372 00:13:17,930 --> 00:13:15,720 scientific instruments as well as 373 00:13:20,329 --> 00:13:17,940 technology demonstrations to the Moon 374 00:13:22,910 --> 00:13:20,339 via the commercial lunar payload 375 00:13:24,769 --> 00:13:22,920 Services Program or eclipse for short 376 00:13:27,170 --> 00:13:24,779 um and so this is um NASA's way of 377 00:13:30,230 --> 00:13:27,180 rapidly acquiring commercial delivery 378 00:13:31,790 --> 00:13:30,240 services to the lunar surface so we have 379 00:13:33,769 --> 00:13:31,800 about seven of these on Deck right now 380 00:13:35,750 --> 00:13:33,779 with over 40 instruments that it will be 381 00:13:37,910 --> 00:13:35,760 flying to the moon and it's part of this 382 00:13:40,310 --> 00:13:37,920 is the Rover you mentioned Viper so 383 00:13:42,590 --> 00:13:40,320 Viper will be roving around looking for 384 00:13:44,990 --> 00:13:42,600 volatiles specifically things such as 385 00:13:46,670 --> 00:13:45,000 water ice and permanently shadowed 386 00:13:48,470 --> 00:13:46,680 regions on the moon so these are areas 387 00:13:50,389 --> 00:13:48,480 that either neither or never get 388 00:13:52,250 --> 00:13:50,399 sunlight or rarely get any sunlight so 389 00:13:54,350 --> 00:13:52,260 good places for water ice to to be 390 00:13:55,850 --> 00:13:54,360 contained so it will be prospecting for 391 00:13:58,189 --> 00:13:55,860 for these areas you know how much is 392 00:13:59,810 --> 00:13:58,199 there what type of deposits do we see 393 00:14:02,090 --> 00:13:59,820 and then how could we possibly use that 394 00:14:03,530 --> 00:14:02,100 for for future human missions to the 395 00:14:05,449 --> 00:14:03,540 Moon yes and then culminating with 396 00:14:06,829 --> 00:14:05,459 Artemis and in our first woman and first 397 00:14:07,910 --> 00:14:06,839 person of color back to the surface of 398 00:14:09,710 --> 00:14:07,920 the Moon 399 00:14:12,590 --> 00:14:09,720 and this is a question for you Vishnu so 400 00:14:15,050 --> 00:14:12,600 you study the Moon from Earth is 401 00:14:16,910 --> 00:14:15,060 studying uh the Moon from Earth during 402 00:14:18,650 --> 00:14:16,920 the lunar eclipse particularly exciting 403 00:14:20,269 --> 00:14:18,660 for your type of research oh yes 404 00:14:22,250 --> 00:14:20,279 absolutely 405 00:14:24,530 --> 00:14:22,260 um so for example right now like during 406 00:14:26,810 --> 00:14:24,540 the full moon phase right uh the surface 407 00:14:29,569 --> 00:14:26,820 of the Moon is really hot it gets heated 408 00:14:32,389 --> 00:14:29,579 up something like 250 degrees Fahrenheit 409 00:14:35,389 --> 00:14:32,399 or you know comparatively like or 120 410 00:14:37,490 --> 00:14:35,399 degrees Celsius so uh these mirrors that 411 00:14:39,050 --> 00:14:37,500 I was talking about on the moon these 412 00:14:42,590 --> 00:14:39,060 are not optimal temperatures for you 413 00:14:44,150 --> 00:14:42,600 know the moon to operate in and so we so 414 00:14:46,910 --> 00:14:44,160 the performance of these the optical 415 00:14:48,350 --> 00:14:46,920 performance of these retro reflectors as 416 00:14:51,470 --> 00:14:48,360 they're called 417 00:14:54,290 --> 00:14:51,480 um they diminished with time right so we 418 00:14:56,930 --> 00:14:54,300 want this kind of a window this Eclipse 419 00:14:59,210 --> 00:14:56,940 offers us this time window wherein you 420 00:15:01,310 --> 00:14:59,220 know the moon passes through the shadow 421 00:15:03,050 --> 00:15:01,320 of the earth so which gives you know 422 00:15:05,810 --> 00:15:03,060 these Optical instruments to kind of 423 00:15:07,850 --> 00:15:05,820 cool down and this enables us to make 424 00:15:10,250 --> 00:15:07,860 measurements right and so what science 425 00:15:12,350 --> 00:15:10,260 we can do from that is that you know 426 00:15:13,970 --> 00:15:12,360 when when when this particular 427 00:15:16,189 --> 00:15:13,980 configuration that we are in right now 428 00:15:19,069 --> 00:15:16,199 which is you know the sun earth and the 429 00:15:21,110 --> 00:15:19,079 moon this enables us to make very high 430 00:15:22,790 --> 00:15:21,120 Precision tests of 431 00:15:26,449 --> 00:15:22,800 um you know the universality of free 432 00:15:27,290 --> 00:15:26,459 fall uh so um during the Apollo 15 I 433 00:15:30,170 --> 00:15:27,300 believe 434 00:15:33,170 --> 00:15:30,180 um the commander uh David Scott he he 435 00:15:36,350 --> 00:15:33,180 dropped um a feather and a hammer at the 436 00:15:38,030 --> 00:15:36,360 same time to demonstrate that uh to show 437 00:15:40,310 --> 00:15:38,040 that you know all objects fall in the 438 00:15:42,470 --> 00:15:40,320 external gravitational field at the same 439 00:15:44,930 --> 00:15:42,480 time and similarly what we're doing here 440 00:15:47,990 --> 00:15:44,940 with this laser ranging measurements is 441 00:15:50,329 --> 00:15:48,000 that uh we're trying to make use of the 442 00:15:53,629 --> 00:15:50,339 Moon and the Earth as test bodies in 443 00:15:56,810 --> 00:15:53,639 this gravitational field and uh so as to 444 00:15:58,790 --> 00:15:56,820 measure the falling of you know this 445 00:16:01,430 --> 00:15:58,800 Earth and Moon system into the 446 00:16:03,769 --> 00:16:01,440 gravitational field of the Sun so by 447 00:16:05,870 --> 00:16:03,779 measuring and comparing uh what we 448 00:16:07,370 --> 00:16:05,880 predict with Theory versus what we 449 00:16:09,650 --> 00:16:07,380 observe with these laser ranging 450 00:16:13,430 --> 00:16:09,660 observations we are able to put a number 451 00:16:15,590 --> 00:16:13,440 to those limits on how accurately was 452 00:16:17,090 --> 00:16:15,600 you know the theory of universality of 453 00:16:19,790 --> 00:16:17,100 free fall based on which you know 454 00:16:22,069 --> 00:16:19,800 Einstein formulated his uh theory of 455 00:16:24,530 --> 00:16:22,079 General Nativity so this is really a 456 00:16:28,610 --> 00:16:24,540 fascinating time and I I just spoke with 457 00:16:31,730 --> 00:16:28,620 one of the um uh one of The Observers in 458 00:16:33,470 --> 00:16:31,740 Grass Station in France and uh if the 459 00:16:35,150 --> 00:16:33,480 weather is clear there they might be 460 00:16:37,670 --> 00:16:35,160 collecting some amazing data for us to 461 00:16:38,810 --> 00:16:37,680 analyze yeah I think Vishnu will if you 462 00:16:40,249 --> 00:16:38,820 don't already know I'll be very excited 463 00:16:42,470 --> 00:16:40,259 to know that we're sending more of these 464 00:16:43,550 --> 00:16:42,480 retro reflectors before the eclipse so 465 00:16:45,230 --> 00:16:43,560 you're going to have lots more science 466 00:16:47,449 --> 00:16:45,240 oh yeah they're not really excited about 467 00:16:49,850 --> 00:16:47,459 that opportunity great that's fantastic 468 00:16:52,370 --> 00:16:49,860 so the last time we set a crude mission 469 00:16:54,230 --> 00:16:52,380 to the moon was about 50 years ago so 470 00:16:56,569 --> 00:16:54,240 why is it important that we send humans 471 00:16:58,069 --> 00:16:56,579 back to the Moon yeah there's a lot of 472 00:16:59,449 --> 00:16:58,079 really important reasons to send humans 473 00:17:01,430 --> 00:16:59,459 back so the last time we were there was 474 00:17:02,629 --> 00:17:01,440 with Apollo and most of the Apollo or 475 00:17:04,189 --> 00:17:02,639 sorry all of the Apollo missions were 476 00:17:06,529 --> 00:17:04,199 kind of in the equatorial region of the 477 00:17:08,809 --> 00:17:06,539 moon so with Artemis we'll be going down 478 00:17:10,069 --> 00:17:08,819 to the South polar region and much like 479 00:17:12,169 --> 00:17:10,079 on Earth if you travel to another 480 00:17:13,189 --> 00:17:12,179 country you know often you know the 481 00:17:15,890 --> 00:17:13,199 Rocks there are completely different 482 00:17:17,449 --> 00:17:15,900 there's just a whole new area so also on 483 00:17:18,590 --> 00:17:17,459 the moon you go down to the South Pole 484 00:17:20,329 --> 00:17:18,600 there's only rocks of different 485 00:17:22,970 --> 00:17:20,339 compositions it's going to be possibly 486 00:17:24,230 --> 00:17:22,980 colder in some areas there's a lot of um 487 00:17:26,449 --> 00:17:24,240 different types of science questions 488 00:17:28,250 --> 00:17:26,459 that we will answer there also we'll 489 00:17:30,289 --> 00:17:28,260 just be developing the the Technologies 490 00:17:32,570 --> 00:17:30,299 and demonstrating the things we need to 491 00:17:34,490 --> 00:17:32,580 to live for longer periods of time on 492 00:17:37,190 --> 00:17:34,500 another planetary body and really 493 00:17:38,810 --> 00:17:37,200 helping prepare ourselves to go to Mars 494 00:17:41,090 --> 00:17:38,820 so talking about 495 00:17:42,610 --> 00:17:41,100 um long-term space travel we had some 496 00:17:45,590 --> 00:17:42,620 really exciting news the other day 497 00:17:48,529 --> 00:17:45,600 scientists had successfully grown plants 498 00:17:50,150 --> 00:17:48,539 from regolith which is lunar soil what 499 00:17:51,710 --> 00:17:50,160 does that mean for future astronauts 500 00:17:53,570 --> 00:17:51,720 yeah yeah so for those who didn't hear 501 00:17:54,890 --> 00:17:53,580 we grew our first plants in lunar 502 00:17:57,289 --> 00:17:54,900 regolith and this is really exciting 503 00:17:58,789 --> 00:17:57,299 scientists hadn't done this before lunar 504 00:18:00,529 --> 00:17:58,799 regolith doesn't have nutrients and 505 00:18:02,390 --> 00:18:00,539 water like like we have here on Earth so 506 00:18:03,470 --> 00:18:02,400 to readily grow plants so there's still 507 00:18:05,390 --> 00:18:03,480 some work we have to do to understand 508 00:18:07,909 --> 00:18:05,400 why the plants grew differently than 509 00:18:10,190 --> 00:18:07,919 they did in you know typical Earth-like 510 00:18:11,810 --> 00:18:10,200 conditions but yeah it's really exciting 511 00:18:13,190 --> 00:18:11,820 it could open up a lot of possibilities 512 00:18:15,650 --> 00:18:13,200 for us to potentially grow our own 513 00:18:17,750 --> 00:18:15,660 plants when we get back to the Moon 514 00:18:20,090 --> 00:18:17,760 so we're nearing totality um have either 515 00:18:22,010 --> 00:18:20,100 of you seen a lunar eclipse before not 516 00:18:24,110 --> 00:18:22,020 that I can remember no I have not either 517 00:18:26,810 --> 00:18:24,120 so it's really really we're all really 518 00:18:28,490 --> 00:18:26,820 excited in the studio today so let's dig 519 00:18:30,950 --> 00:18:28,500 into some questions we're getting online 520 00:18:33,590 --> 00:18:30,960 on social media 521 00:18:35,870 --> 00:18:33,600 um so let's uh see who we what questions 522 00:18:38,090 --> 00:18:35,880 we have uh we have a question from A 523 00:18:40,610 --> 00:18:38,100 Midsummer on Twitter and they ask is 524 00:18:42,590 --> 00:18:40,620 there a delay in real time for data from 525 00:18:45,890 --> 00:18:42,600 the Moon like how there is an eight 526 00:18:49,130 --> 00:18:45,900 million minute delay from the Sun 527 00:18:51,230 --> 00:18:49,140 um yes and um so this is precisely the 528 00:18:56,090 --> 00:18:51,240 time that we measure with the laser data 529 00:18:58,789 --> 00:18:56,100 right so it takes 2.5 ish seconds uh for 530 00:19:01,250 --> 00:18:58,799 a light beam to go from Earth bounce 531 00:19:03,770 --> 00:19:01,260 back the um you know these mirrors and 532 00:19:05,390 --> 00:19:03,780 come back uh to those telescopes so 533 00:19:08,450 --> 00:19:05,400 which means that you know one way would 534 00:19:09,669 --> 00:19:08,460 be like half of that value 1.25 535 00:19:12,289 --> 00:19:09,679 um seconds 536 00:19:15,350 --> 00:19:12,299 wow pretty fast compared to you know the 537 00:19:17,029 --> 00:19:15,360 eight minute yeah much faster 538 00:19:19,070 --> 00:19:17,039 and so on the next we have a next 539 00:19:21,529 --> 00:19:19,080 question from Trevor on Twitter and they 540 00:19:22,789 --> 00:19:21,539 asked why does the moon turn red during 541 00:19:24,770 --> 00:19:22,799 an eclipse 542 00:19:26,510 --> 00:19:24,780 yeah so the moon we call this a blood 543 00:19:28,789 --> 00:19:26,520 moon when it turns red during an eclipse 544 00:19:30,710 --> 00:19:28,799 and this is because as as the Earth is 545 00:19:32,450 --> 00:19:30,720 blocking the Sun's light the sun's 546 00:19:34,490 --> 00:19:32,460 sunlight is still passing through 547 00:19:36,169 --> 00:19:34,500 Earth's atmosphere and when this happens 548 00:19:37,610 --> 00:19:36,179 you're kind of Bluer wavelengths of 549 00:19:39,529 --> 00:19:37,620 light gets scattered by Earth's 550 00:19:41,029 --> 00:19:39,539 atmosphere but the red wavelengths of 551 00:19:42,049 --> 00:19:41,039 light still pass through and that's the 552 00:19:43,610 --> 00:19:42,059 wavelength of light you're seeing 553 00:19:45,590 --> 00:19:43,620 reflected off the surface of the Moon 554 00:19:48,710 --> 00:19:45,600 it's much like reflecting back Earth's 555 00:19:50,570 --> 00:19:48,720 sunrises and sunsets in a sense 556 00:19:53,150 --> 00:19:50,580 okay so our next question is from 557 00:19:55,669 --> 00:19:53,160 musical wolves on YouTube and they ask 558 00:19:57,770 --> 00:19:55,679 why does a total lunar eclipse sorry 559 00:19:59,210 --> 00:19:57,780 what does a total lunar eclipse look 560 00:20:02,029 --> 00:19:59,220 like from the International Space 561 00:20:06,649 --> 00:20:04,490 well I think they will definitely enjoy 562 00:20:08,330 --> 00:20:06,659 a more clearer view because you know 563 00:20:10,370 --> 00:20:08,340 there's no atmosphere up there right 564 00:20:13,010 --> 00:20:10,380 from the uh International Space Station 565 00:20:15,230 --> 00:20:13,020 so I think it's going to look like how 566 00:20:17,450 --> 00:20:15,240 we see it on Earth but just beautiful 567 00:20:19,970 --> 00:20:17,460 much more prettier because you know it's 568 00:20:21,289 --> 00:20:19,980 without without all the atmosphere in 569 00:20:24,110 --> 00:20:21,299 between all the clouds like we have 570 00:20:29,810 --> 00:20:28,010 uh and Sydney asks um why are we going 571 00:20:31,850 --> 00:20:29,820 back to the Moon 572 00:20:33,289 --> 00:20:31,860 that's a great question um some of the 573 00:20:34,490 --> 00:20:33,299 reasons I mentioned before um the 574 00:20:36,169 --> 00:20:34,500 different variety of science questions 575 00:20:37,730 --> 00:20:36,179 that we can answer 576 00:20:39,289 --> 00:20:37,740 um you know the moon hasn't really I've 577 00:20:41,330 --> 00:20:39,299 been there done that place um the South 578 00:20:43,250 --> 00:20:41,340 polar region is is a whole new area we 579 00:20:44,810 --> 00:20:43,260 haven't explored yet there are resources 580 00:20:46,730 --> 00:20:44,820 there that weren't really available to 581 00:20:48,830 --> 00:20:46,740 us um for the Apollo missions again 582 00:20:51,470 --> 00:20:48,840 because of the presence of water ice in 583 00:20:52,850 --> 00:20:51,480 the South polar area so we can really 584 00:20:55,250 --> 00:20:52,860 demonstrate how we can pull out these 585 00:20:57,049 --> 00:20:55,260 resources and use them for for water or 586 00:20:59,149 --> 00:20:57,059 even for making Rocket Fuel that can 587 00:21:00,590 --> 00:20:59,159 then send us onto Mars but but yeah so a 588 00:21:02,090 --> 00:21:00,600 lot of it is is you know the science and 589 00:21:03,710 --> 00:21:02,100 then also just developing these 590 00:21:05,330 --> 00:21:03,720 Technologies and getting that experience 591 00:21:08,029 --> 00:21:05,340 we need in order to go on to places like 592 00:21:10,789 --> 00:21:08,039 Mars and Beyond 593 00:21:12,830 --> 00:21:10,799 okay so our next question is from Denise 594 00:21:14,750 --> 00:21:12,840 Wright an Earth and space science 595 00:21:17,029 --> 00:21:14,760 teacher from Myrtle Beach in South 596 00:21:19,370 --> 00:21:17,039 Carolina and they ask how much does the 597 00:21:21,169 --> 00:21:19,380 surface temperature of the Moon drop on 598 00:21:22,970 --> 00:21:21,179 that side that we are seeing during this 599 00:21:24,409 --> 00:21:22,980 eclipse 600 00:21:25,190 --> 00:21:24,419 oh okay 601 00:21:28,549 --> 00:21:25,200 um 602 00:21:30,409 --> 00:21:28,559 I think it's about a few uh tens of uh 603 00:21:32,690 --> 00:21:30,419 Calvin 604 00:21:35,690 --> 00:21:32,700 um at least you'll get that duration 605 00:21:38,029 --> 00:21:35,700 over which um you know I know the the 606 00:21:40,490 --> 00:21:38,039 entire it takes about when during a full 607 00:21:42,710 --> 00:21:40,500 moon phase it goes up to like 250 degree 608 00:21:46,190 --> 00:21:42,720 Fahrenheit or which is you know it's 609 00:21:47,750 --> 00:21:46,200 like um 120 Celsius but I think yeah I'm 610 00:21:49,850 --> 00:21:47,760 not very familiar with the exact value 611 00:21:51,409 --> 00:21:49,860 because you know we this is a very long 612 00:21:53,450 --> 00:21:51,419 Eclipse which means like you know it's 613 00:21:55,850 --> 00:21:53,460 it has sufficient time to cool down but 614 00:21:57,649 --> 00:21:55,860 the the it takes time for the lunar 615 00:22:00,710 --> 00:21:57,659 regolith to respond to it you know 616 00:22:03,409 --> 00:22:00,720 there's some thermal inertia to it so um 617 00:22:04,610 --> 00:22:03,419 yeah I'd say a couple of degrees to as a 618 00:22:07,610 --> 00:22:04,620 guess yeah 619 00:22:10,370 --> 00:22:07,620 I don't have a better guess 620 00:22:13,490 --> 00:22:10,380 okay so we have a question from Trevor 621 00:22:14,750 --> 00:22:13,500 polinga on Twitter uh and they are 622 00:22:17,270 --> 00:22:14,760 asking on behalf of the pulling good 623 00:22:19,669 --> 00:22:17,280 kids has anyone ever been on the moon 624 00:22:21,289 --> 00:22:19,679 during a lunar eclipse 625 00:22:22,850 --> 00:22:21,299 great question I believe the answer is 626 00:22:24,409 --> 00:22:22,860 no I don't I don't know if one happened 627 00:22:26,570 --> 00:22:24,419 during Apollo or not I'd actually I'm 628 00:22:27,470 --> 00:22:26,580 not entirely sure but I imagine if if 629 00:22:29,090 --> 00:22:27,480 they had been they probably would have 630 00:22:30,710 --> 00:22:29,100 gotten a good image for us 631 00:22:32,810 --> 00:22:30,720 I think um you know what what they would 632 00:22:34,909 --> 00:22:32,820 be seeing if during the lunar eclipse is 633 00:22:36,710 --> 00:22:34,919 like uh just like during the solar 634 00:22:38,810 --> 00:22:36,720 eclipse you know when when you get the 635 00:22:42,110 --> 00:22:38,820 totality we see that annular ring around 636 00:22:44,570 --> 00:22:42,120 the Moon similarly you can expect you 637 00:22:45,890 --> 00:22:44,580 know when we during a lunar eclipse if 638 00:22:48,289 --> 00:22:45,900 you were to be on the surface of the 639 00:22:50,090 --> 00:22:48,299 Moon looking at the Earth it would be 640 00:22:53,029 --> 00:22:50,100 such a fantastic view because you'll see 641 00:22:55,490 --> 00:22:53,039 uh you know not that Horizon Sunset that 642 00:22:57,950 --> 00:22:55,500 we we see on Earth but you know it'd be 643 00:23:00,350 --> 00:22:57,960 like a ring of sunset right around 644 00:23:01,610 --> 00:23:00,360 around the around the earth with you 645 00:23:03,590 --> 00:23:01,620 know the sun in the background I think 646 00:23:05,750 --> 00:23:03,600 it's a spectacular view I'd you know I'd 647 00:23:07,970 --> 00:23:05,760 I'd love to be there in that place to 648 00:23:09,890 --> 00:23:07,980 see that view yeah so that would be so 649 00:23:11,570 --> 00:23:09,900 that would be like a red ring around 650 00:23:13,310 --> 00:23:11,580 Earth is that what you mean yes I think 651 00:23:16,430 --> 00:23:13,320 so yeah that's how it would look like I 652 00:23:18,710 --> 00:23:16,440 believe um only right you know at 653 00:23:21,049 --> 00:23:18,720 Goddard wood you know I'm sure he has 654 00:23:22,610 --> 00:23:21,059 made a simulation on this that shows 655 00:23:24,049 --> 00:23:22,620 that particular video you know check 656 00:23:29,270 --> 00:23:24,059 that out 657 00:23:34,370 --> 00:23:32,029 um when we go back to the moon will we 658 00:23:36,110 --> 00:23:34,380 set it up as a permanent settlement 659 00:23:38,149 --> 00:23:36,120 yeah so so we are looking at 660 00:23:40,370 --> 00:23:38,159 establishing a lunar base on the moon 661 00:23:42,409 --> 00:23:40,380 you know having more you know permanent 662 00:23:44,750 --> 00:23:42,419 or semi-permanent architecture uh that 663 00:23:46,549 --> 00:23:44,760 we can um then go to at a more frequent 664 00:23:48,830 --> 00:23:46,559 basis you know send or you know cruise 665 00:23:50,570 --> 00:23:48,840 on a regular basis to habitats and then 666 00:23:51,710 --> 00:23:50,580 have long duration Rovers and things 667 00:23:53,510 --> 00:23:51,720 like that so yes it's definitely 668 00:23:56,450 --> 00:23:53,520 something that NASA is working towards 669 00:23:59,870 --> 00:23:56,460 oh fantastic okay so our next question 670 00:24:02,450 --> 00:23:59,880 is from anab on Twitter and they ask is 671 00:24:03,710 --> 00:24:02,460 a lunar Mission launch possible during a 672 00:24:05,450 --> 00:24:03,720 lunar eclipse 673 00:24:07,549 --> 00:24:05,460 I mean not during the launch but while 674 00:24:10,490 --> 00:24:07,559 it's in orbit and maneuvering to get 675 00:24:14,149 --> 00:24:10,500 into the lunar orbits 676 00:24:16,190 --> 00:24:14,159 I don't see uh a reason why not 677 00:24:17,570 --> 00:24:16,200 um yeah yeah I mean I think 678 00:24:19,010 --> 00:24:17,580 communication with Earth is one of the 679 00:24:21,289 --> 00:24:19,020 most important things and then good 680 00:24:22,250 --> 00:24:21,299 conditions to launch offers so the lunar 681 00:24:23,269 --> 00:24:22,260 eclipse shouldn't affect those things 682 00:24:24,950 --> 00:24:23,279 yeah 683 00:24:27,409 --> 00:24:24,960 so do you think there's a chance um 684 00:24:28,549 --> 00:24:27,419 finding future lunar missions to do for 685 00:24:30,169 --> 00:24:28,559 that to happen 686 00:24:32,029 --> 00:24:30,179 yeah I think it'd be really exciting I 687 00:24:33,470 --> 00:24:32,039 mean yeah you know there's cool visuals 688 00:24:36,710 --> 00:24:33,480 and probably in school science you know 689 00:24:40,789 --> 00:24:38,870 okay so our next question is from snazzy 690 00:24:42,110 --> 00:24:40,799 zazzy on Twitter and they ask with the 691 00:24:43,909 --> 00:24:42,120 awesomest crew deal with any 692 00:24:46,430 --> 00:24:43,919 abnormalities if they were on the moon 693 00:24:49,730 --> 00:24:46,440 during a lunar eclipse for example extra 694 00:24:52,610 --> 00:24:50,570 um 695 00:24:54,710 --> 00:24:52,620 I think one of the difficulties that 696 00:24:56,990 --> 00:24:54,720 they would potentially face is you know 697 00:24:59,570 --> 00:24:57,000 the lack of light right because you know 698 00:25:00,830 --> 00:24:59,580 you have a good amount of sunlight 699 00:25:02,630 --> 00:25:00,840 coming in 700 00:25:05,330 --> 00:25:02,640 um if they were to be in the you know in 701 00:25:07,970 --> 00:25:05,340 your side and suddenly it would be like 702 00:25:09,470 --> 00:25:07,980 a you know a diminished light or a much 703 00:25:11,810 --> 00:25:09,480 dimmer light than you know they are 704 00:25:14,149 --> 00:25:11,820 enjoying too and I just hope they're not 705 00:25:17,029 --> 00:25:14,159 in one of those abundantly shattered 706 00:25:20,029 --> 00:25:17,039 reasons when well you know when you're 707 00:25:21,710 --> 00:25:20,039 doing that so but I think I think that's 708 00:25:23,029 --> 00:25:21,720 that's about it yeah and I think one 709 00:25:24,350 --> 00:25:23,039 thing one thing to remember too is that 710 00:25:26,149 --> 00:25:24,360 generally these eclipses are not very 711 00:25:28,490 --> 00:25:26,159 long you're the one tonight is is quite 712 00:25:30,289 --> 00:25:28,500 a bit longer than what we typically see 713 00:25:32,390 --> 00:25:30,299 but usually they're on the order of a 714 00:25:33,830 --> 00:25:32,400 few minutes so you know even again yeah 715 00:25:35,269 --> 00:25:33,840 light the lack of light could be 716 00:25:37,130 --> 00:25:35,279 probably the biggest issue to be 717 00:25:38,870 --> 00:25:37,140 concerned with 718 00:25:41,149 --> 00:25:38,880 okay so we're going to be taking more of 719 00:25:43,070 --> 00:25:41,159 your questions later on in the show but 720 00:25:45,169 --> 00:25:43,080 we are nearing totality now which is 721 00:25:47,269 --> 00:25:45,179 really really exciting so let's head 722 00:25:48,649 --> 00:25:47,279 back to James to see where we are what 723 00:25:50,510 --> 00:25:48,659 we're seeing on the feeds and what other 724 00:25:52,370 --> 00:25:50,520 people around the world are seeing 725 00:25:53,750 --> 00:25:52,380 yeah Joy this is the big moment you know 726 00:25:55,130 --> 00:25:53,760 if you're keeping score at home or just 727 00:25:57,230 --> 00:25:55,140 about four minutes away from the main 728 00:25:58,970 --> 00:25:57,240 event totality and if I swipe back to 729 00:26:00,350 --> 00:25:58,980 the screen here we've been tracking this 730 00:26:02,450 --> 00:26:00,360 View for the past couple minutes here in 731 00:26:03,710 --> 00:26:02,460 orzazat Morocco they have a beautiful 732 00:26:05,990 --> 00:26:03,720 clear night there in the desert right 733 00:26:07,970 --> 00:26:06,000 now you can see just the last little 734 00:26:09,950 --> 00:26:07,980 sliver of brightness here before the 735 00:26:11,090 --> 00:26:09,960 Moon is eclipsed here for us and we're 736 00:26:12,590 --> 00:26:11,100 starting to get some really interesting 737 00:26:13,669 --> 00:26:12,600 reddish color creeping across and just 738 00:26:15,529 --> 00:26:13,679 before we went on you're telling me 739 00:26:17,630 --> 00:26:15,539 something interesting about the times 740 00:26:18,769 --> 00:26:17,640 that we're displaying there there's you 741 00:26:20,149 --> 00:26:18,779 know they're not down to the exact 742 00:26:23,750 --> 00:26:20,159 second you know we have them at like 11 743 00:26:25,549 --> 00:26:23,760 29. why is that you know not precise for 744 00:26:27,169 --> 00:26:25,559 us right you would think that we know 745 00:26:28,669 --> 00:26:27,179 the geometry of the Shadow and we can 746 00:26:31,210 --> 00:26:28,679 just figure that out but it turns out 747 00:26:33,590 --> 00:26:31,220 that the width of the Shadow at the Moon 748 00:26:35,210 --> 00:26:33,600 is affected by the atmosphere and of 749 00:26:37,010 --> 00:26:35,220 course the atmosphere on Earth is 750 00:26:39,169 --> 00:26:37,020 constantly changing 751 00:26:41,810 --> 00:26:39,179 um it enlarges the Shadow by about one 752 00:26:44,149 --> 00:26:41,820 to two percent but for each Eclipse it's 753 00:26:46,850 --> 00:26:44,159 a little bit different so when we do the 754 00:26:50,750 --> 00:26:46,860 calculations we use an average value but 755 00:26:52,310 --> 00:26:50,760 um we don't know precisely what that 756 00:26:54,230 --> 00:26:52,320 number is going to be until it actually 757 00:26:57,950 --> 00:26:54,240 happens and this is actually something 758 00:27:01,370 --> 00:26:57,960 that um citizen scientists can help with 759 00:27:04,430 --> 00:27:01,380 um while the shadow is moving across you 760 00:27:06,649 --> 00:27:04,440 can time when that edge hits each crater 761 00:27:10,070 --> 00:27:06,659 and you can do that at the end of 762 00:27:13,970 --> 00:27:10,080 totality as well and this sort of pins 763 00:27:15,830 --> 00:27:13,980 down the size of that shadow and so I 764 00:27:17,690 --> 00:27:15,840 mean I think it's probably surprising to 765 00:27:19,310 --> 00:27:17,700 people that we were not certain to the 766 00:27:22,190 --> 00:27:19,320 millisecond when these things are going 767 00:27:24,590 --> 00:27:22,200 to happen but you know uh science is a 768 00:27:26,630 --> 00:27:24,600 little bit messy sometimes and and we 769 00:27:28,669 --> 00:27:26,640 don't even fully understand all of the 770 00:27:30,590 --> 00:27:28,679 effects that are changing the size of 771 00:27:32,029 --> 00:27:30,600 that shadow so it's it's an ongoing 772 00:27:33,529 --> 00:27:32,039 question yeah and we've been watching 773 00:27:34,669 --> 00:27:33,539 them kind of adjusting the exposure a 774 00:27:36,289 --> 00:27:34,679 bit of the camera here to get this 775 00:27:37,370 --> 00:27:36,299 really dark area of the Moon and a 776 00:27:38,690 --> 00:27:37,380 couple of our other feeds as well have 777 00:27:40,190 --> 00:27:38,700 been kind of doing the same pattern as 778 00:27:41,630 --> 00:27:40,200 well here too can you tell us a little 779 00:27:42,590 --> 00:27:41,640 bit about this red color we're seeing 780 00:27:43,610 --> 00:27:42,600 starting to come up here if I'm 781 00:27:45,470 --> 00:27:43,620 understanding correctly it's a 782 00:27:48,350 --> 00:27:45,480 projection of all the sunrises and 783 00:27:50,090 --> 00:27:48,360 sunsets it absolutely is um imagine how 784 00:27:52,789 --> 00:27:50,100 beautiful that would be to be on the 785 00:27:54,409 --> 00:27:52,799 moon and see it um yeah this is a color 786 00:27:56,510 --> 00:27:54,419 that's coming from all the sunrises and 787 00:27:58,010 --> 00:27:56,520 sunsets it's the it's the light filtered 788 00:27:59,510 --> 00:27:58,020 through the atmosphere 789 00:28:01,669 --> 00:27:59,520 um all the blue light is scattered away 790 00:28:03,409 --> 00:28:01,679 the red light is sort of refracted into 791 00:28:05,269 --> 00:28:03,419 that total shadow 792 00:28:07,789 --> 00:28:05,279 um and so that's why it's appearing red 793 00:28:09,289 --> 00:28:07,799 it's very possible that the color of 794 00:28:12,470 --> 00:28:09,299 this eclipse is somewhat darker than 795 00:28:15,289 --> 00:28:12,480 usual because of an eruption in Tonga in 796 00:28:17,210 --> 00:28:15,299 December and January the number of 797 00:28:19,970 --> 00:28:17,220 aerosols of particles in the atmosphere 798 00:28:22,850 --> 00:28:19,980 can affect the darkness and so there's a 799 00:28:24,769 --> 00:28:22,860 scale that we rate the darkness the 800 00:28:26,630 --> 00:28:24,779 scale goes from zero to four the scale 801 00:28:28,610 --> 00:28:26,640 was invented by an astronomer named 802 00:28:30,649 --> 00:28:28,620 danjon right 803 00:28:32,149 --> 00:28:30,659 um and so that's another thing that 804 00:28:33,590 --> 00:28:32,159 people can do they can go outside and 805 00:28:35,269 --> 00:28:33,600 sort of Judge the darkness of this 806 00:28:37,789 --> 00:28:35,279 compared to other eclipses and this 807 00:28:39,470 --> 00:28:37,799 one's looking a little dark yeah if 808 00:28:40,909 --> 00:28:39,480 you're a bit luckier than us at home and 809 00:28:41,990 --> 00:28:40,919 you don't have cloud cover what kind of 810 00:28:43,070 --> 00:28:42,000 things can you see with the naked eye 811 00:28:45,350 --> 00:28:43,080 just looking up at the moon at this 812 00:28:46,970 --> 00:28:45,360 point right you know I I think even with 813 00:28:48,769 --> 00:28:46,980 the naked eye you can distinguish the 814 00:28:51,769 --> 00:28:48,779 dark parts of the Moon from the brighter 815 00:28:53,990 --> 00:28:51,779 Parts the dark parts are called Mare and 816 00:28:57,409 --> 00:28:54,000 these are places where lava has infilled 817 00:28:59,750 --> 00:28:57,419 large depressions so this is tranquility 818 00:29:04,010 --> 00:28:59,760 where Apollo 11 landed and serenity is 819 00:29:06,169 --> 00:29:04,020 next to it and Ibrahim is up here these 820 00:29:07,970 --> 00:29:06,179 are basalts these are like volcanic 821 00:29:11,690 --> 00:29:07,980 rocks and they're very dark you think of 822 00:29:13,549 --> 00:29:11,700 uh black beaches in Hawaii so you have a 823 00:29:15,769 --> 00:29:13,559 geology background you know about this 824 00:29:17,690 --> 00:29:15,779 um and then the the lighter parts are 825 00:29:20,389 --> 00:29:17,700 called Highlands and these are older 826 00:29:22,730 --> 00:29:20,399 they're more heavily cratered but 827 00:29:24,230 --> 00:29:22,740 they're not filled with lava and so 828 00:29:26,029 --> 00:29:24,240 that's something you can notice right 829 00:29:28,370 --> 00:29:26,039 away just with the naked eye and looking 830 00:29:29,990 --> 00:29:28,380 at my watch right now it is 11 29 here 831 00:29:31,669 --> 00:29:30,000 on the East Coast this is the moment 832 00:29:33,769 --> 00:29:31,679 we've all been waiting for totality here 833 00:29:35,210 --> 00:29:33,779 there's just that last little bit of 834 00:29:36,830 --> 00:29:35,220 sliver of light here so we're just gonna 835 00:29:38,570 --> 00:29:36,840 sit back and watch this moment happen 836 00:29:40,490 --> 00:29:38,580 wish we could be doing this from outside 837 00:29:42,049 --> 00:29:40,500 here in the rocket oh my God it would be 838 00:29:43,730 --> 00:29:42,059 really nice but you know this is still 839 00:29:45,110 --> 00:29:43,740 an incredible view here from orzazad 840 00:29:46,970 --> 00:29:45,120 well and one of the things that you'll 841 00:29:48,889 --> 00:29:46,980 notice I mean this bright part is just 842 00:29:50,810 --> 00:29:48,899 because the difference in exposure so 843 00:29:52,549 --> 00:29:50,820 this part of the moon right here is 844 00:29:54,350 --> 00:29:52,559 closer to the center of the Shadow and 845 00:29:55,850 --> 00:29:54,360 that's where it's darker so throughout 846 00:29:58,310 --> 00:29:55,860 totality you're going to see the sort of 847 00:29:59,630 --> 00:29:58,320 gradient from one side to the other and 848 00:30:01,010 --> 00:29:59,640 so if you're at home you know this is 849 00:30:02,090 --> 00:30:01,020 the moment to run outside keep us in 850 00:30:03,350 --> 00:30:02,100 your back pocket listening on your 851 00:30:05,330 --> 00:30:03,360 headphones as you run out there to take 852 00:30:06,529 --> 00:30:05,340 some pictures for some play-by-play but 853 00:30:07,850 --> 00:30:06,539 what are some tips for this moment you 854 00:30:09,169 --> 00:30:07,860 kind of went over some earlier here but 855 00:30:10,310 --> 00:30:09,179 you know this is the moment to take a 856 00:30:11,930 --> 00:30:10,320 picture and share with us wherever 857 00:30:13,669 --> 00:30:11,940 you're watching this right well and the 858 00:30:15,230 --> 00:30:13,679 lovely thing about a total lunar eclipse 859 00:30:17,090 --> 00:30:15,240 is that it lasts for a little while so 860 00:30:18,230 --> 00:30:17,100 this is an opportunity just to get 861 00:30:20,930 --> 00:30:18,240 outside 862 00:30:23,029 --> 00:30:20,940 um it's an outdoor activity you bring a 863 00:30:25,070 --> 00:30:23,039 lawn chair and you kind of sit back and 864 00:30:28,310 --> 00:30:25,080 you think about the fact that we're in 865 00:30:30,950 --> 00:30:28,320 the earth's Shadow every night but this 866 00:30:32,330 --> 00:30:30,960 night you are sharing that shadow with a 867 00:30:34,490 --> 00:30:32,340 body that's a quarter of a million miles 868 00:30:35,870 --> 00:30:34,500 away it's the same Shadow which is kind 869 00:30:37,430 --> 00:30:35,880 of cool and I can't help but think about 870 00:30:38,690 --> 00:30:37,440 what that view would look like on the 871 00:30:40,970 --> 00:30:38,700 moon you know imagine if you're an 872 00:30:42,529 --> 00:30:40,980 astronaut up there observing that I I 873 00:30:44,090 --> 00:30:42,539 yeah I would love that I think it was 874 00:30:46,730 --> 00:30:44,100 mentioned a little earlier 875 00:30:49,250 --> 00:30:46,740 um a question came in about whether or 876 00:30:52,370 --> 00:30:49,260 not Apollo follow or or any astronaut 877 00:30:54,169 --> 00:30:52,380 had seen a total solar total lunar 878 00:30:55,610 --> 00:30:54,179 eclipse from the Moon 879 00:30:58,370 --> 00:30:55,620 almost 880 00:31:01,430 --> 00:30:58,380 um a plan for one of the Apollo missions 881 00:31:04,370 --> 00:31:01,440 was to leave the TV camera pointed at 882 00:31:06,230 --> 00:31:04,380 the Earth and an eclipse is going to 883 00:31:08,210 --> 00:31:06,240 take place a few days later but the 884 00:31:11,630 --> 00:31:08,220 camera malfunctioned and that didn't 885 00:31:13,730 --> 00:31:11,640 have that opportunity so it's another of 886 00:31:15,889 --> 00:31:13,740 the thousand reasons to go back 887 00:31:17,990 --> 00:31:15,899 um I I think the opportunity to see it 888 00:31:19,370 --> 00:31:18,000 from there would just be amazing yeah 889 00:31:21,409 --> 00:31:19,380 and some questions are coming in from 890 00:31:23,570 --> 00:31:21,419 social media here as well too James itso 891 00:31:26,810 --> 00:31:23,580 on Twitter asks how often does this type 892 00:31:28,730 --> 00:31:26,820 of lunar eclipse occur so total lunar 893 00:31:30,409 --> 00:31:28,740 eclipses happen about every six months 894 00:31:32,570 --> 00:31:30,419 but they're not always visible from 895 00:31:34,310 --> 00:31:32,580 where you are the nice thing about lunar 896 00:31:36,049 --> 00:31:34,320 eclipses is that half the Earth can see 897 00:31:37,570 --> 00:31:36,059 them but it might not be the half you 898 00:31:41,649 --> 00:31:37,580 happen to be in 899 00:31:43,970 --> 00:31:41,659 so mostly every six months sometimes 900 00:31:48,169 --> 00:31:43,980 it's five months in between and 901 00:31:50,810 --> 00:31:48,179 sometimes you can have two in a row and 902 00:31:52,370 --> 00:31:50,820 occasionally that six month pattern is 903 00:31:54,169 --> 00:31:52,380 sort of broken and what you get is sort 904 00:31:56,169 --> 00:31:54,179 of partial and penumbral and less 905 00:31:58,250 --> 00:31:56,179 interesting eclipses for a little while 906 00:32:00,289 --> 00:31:58,260 and then suddenly you get a string of 907 00:32:02,029 --> 00:32:00,299 totals again amazing and you've had a 908 00:32:03,889 --> 00:32:02,039 chance to really study the Moon up close 909 00:32:05,810 --> 00:32:03,899 with some of the missions from NASA like 910 00:32:07,310 --> 00:32:05,820 the lunar reconnaissance Orbiter to get 911 00:32:08,269 --> 00:32:07,320 some really cool visualizations can you 912 00:32:09,710 --> 00:32:08,279 tell us a bit more about some of those 913 00:32:11,690 --> 00:32:09,720 types of things right so this is 914 00:32:13,250 --> 00:32:11,700 actually what I do here I've been 915 00:32:17,269 --> 00:32:13,260 working with lunar Constance Orbiter 916 00:32:19,789 --> 00:32:17,279 data since it launched in 2009 and lro 917 00:32:22,310 --> 00:32:19,799 is creating global maps of the Moon that 918 00:32:24,350 --> 00:32:22,320 are way more detailed than anything we 919 00:32:26,630 --> 00:32:24,360 had before I think people had the 920 00:32:27,950 --> 00:32:26,640 impression that since Apollo we had the 921 00:32:29,930 --> 00:32:27,960 moon all figured out and we actually 922 00:32:32,750 --> 00:32:29,940 knew almost nothing about it I mean we 923 00:32:35,210 --> 00:32:32,760 we landed in six pinpoints on the 924 00:32:38,630 --> 00:32:35,220 surface and that's what we got from 925 00:32:39,850 --> 00:32:38,640 Apollo um but lro has been mapping the 926 00:32:42,649 --> 00:32:39,860 entire Moon 927 00:32:45,710 --> 00:32:42,659 we have millions of pictures of the 928 00:32:48,889 --> 00:32:45,720 surface we have a very detailed shape of 929 00:32:50,509 --> 00:32:48,899 the surface we have a record of how the 930 00:32:52,490 --> 00:32:50,519 temperature changes on the surface and 931 00:32:54,169 --> 00:32:52,500 this also tells us something about we 932 00:32:55,549 --> 00:32:54,179 got another oh wow yeah yeah movies 933 00:32:57,169 --> 00:32:55,559 coming in here this is from San Diego 934 00:32:59,029 --> 00:32:57,179 looks like a beautiful clear night there 935 00:33:00,409 --> 00:32:59,039 as well too which you know we got some 936 00:33:02,330 --> 00:33:00,419 questions here on social media Robert 937 00:33:03,950 --> 00:33:02,340 Schloss is asking does you know this 938 00:33:05,090 --> 00:33:03,960 Eclipse here affect the tide San Diego 939 00:33:06,649 --> 00:33:05,100 they'd be concerned about without Wilson 940 00:33:08,029 --> 00:33:06,659 surfing you know how's that going to 941 00:33:10,009 --> 00:33:08,039 affect their their surface occasionally 942 00:33:11,330 --> 00:33:10,019 I mean there are there are King tides 943 00:33:13,669 --> 00:33:11,340 and these are things that happen during 944 00:33:15,950 --> 00:33:13,679 full moons and new moons um 945 00:33:17,630 --> 00:33:15,960 the eclipse isn't special in that in 946 00:33:19,669 --> 00:33:17,640 that respect but it is one of those 947 00:33:21,649 --> 00:33:19,679 times where you might get a little bit 948 00:33:24,289 --> 00:33:21,659 of a title effect but it won't be 949 00:33:26,269 --> 00:33:24,299 enormous you don't have to worry about 950 00:33:28,250 --> 00:33:26,279 um you know tidal waves or anything uh 951 00:33:29,389 --> 00:33:28,260 silly like that yeah yeah let's check 952 00:33:30,769 --> 00:33:29,399 out some of the other fees here too so 953 00:33:32,990 --> 00:33:30,779 this is San Diego I'm going to check 954 00:33:34,070 --> 00:33:33,000 back on Rome which they look like they 955 00:33:35,029 --> 00:33:34,080 have a little bit of cloud cover we've 956 00:33:37,070 --> 00:33:35,039 got some buildings there you're 957 00:33:38,330 --> 00:33:37,080 mentioning that if this was a little bit 958 00:33:40,250 --> 00:33:38,340 clearer you'd be able to see the moon 959 00:33:42,350 --> 00:33:40,260 you know perched right there yeah 960 00:33:44,509 --> 00:33:42,360 because the Moon is setting in Rome um 961 00:33:46,970 --> 00:33:44,519 it would be low in the sky and so that 962 00:33:49,250 --> 00:33:46,980 was an opportunity to maybe catch the 963 00:33:50,870 --> 00:33:49,260 moon with 964 00:33:52,190 --> 00:33:50,880 all of this beautiful architecture yeah 965 00:33:53,570 --> 00:33:52,200 they're adjusting a little bit maybe 966 00:33:55,190 --> 00:33:53,580 it'll come into Focus here in a second 967 00:33:56,389 --> 00:33:55,200 while they're doing that let's let's 968 00:33:57,409 --> 00:33:56,399 scroll down here and check out some of 969 00:33:59,149 --> 00:33:57,419 the other ones here this is one from 970 00:34:00,470 --> 00:33:59,159 Cartersville Georgia the first one we I 971 00:34:02,870 --> 00:34:00,480 opened with tonight here too they got 972 00:34:04,310 --> 00:34:02,880 some beautiful red color here too and so 973 00:34:05,450 --> 00:34:04,320 there's quite a gradient of the color 974 00:34:08,569 --> 00:34:05,460 here as well you're mentioning that 975 00:34:10,669 --> 00:34:08,579 scale the digital scale as well right 976 00:34:12,409 --> 00:34:10,679 um yeah and um so you can tell right 977 00:34:14,329 --> 00:34:12,419 away that the part of the Moon that's 978 00:34:15,889 --> 00:34:14,339 deepest in the shadow is over on this 979 00:34:17,990 --> 00:34:15,899 side this is something else that you can 980 00:34:19,790 --> 00:34:18,000 see with the naked eye and it 981 00:34:21,109 --> 00:34:19,800 um you know the feeds don't fully 982 00:34:22,849 --> 00:34:21,119 capture it if you're able to go outside 983 00:34:25,129 --> 00:34:22,859 and see it with your naked eye the color 984 00:34:26,450 --> 00:34:25,139 is amazing um something I've noticed 985 00:34:28,849 --> 00:34:26,460 with a couple of these total lunar 986 00:34:30,950 --> 00:34:28,859 eclipses is that the Moon looks weirdly 987 00:34:33,169 --> 00:34:30,960 almost transparent it looks like you can 988 00:34:35,629 --> 00:34:33,179 see space behind it it's not really but 989 00:34:38,270 --> 00:34:35,639 it's an effect of that sort of color 990 00:34:39,950 --> 00:34:38,280 gradient and the dark red and the 991 00:34:42,710 --> 00:34:39,960 surprising darkness of the Moon I mean 992 00:34:43,730 --> 00:34:42,720 this is Right Way darker than a normal 993 00:34:45,470 --> 00:34:43,740 full moon 994 00:34:46,609 --> 00:34:45,480 um so it just looks weird and yeah 995 00:34:48,470 --> 00:34:46,619 that's one of the things that's fun 996 00:34:49,790 --> 00:34:48,480 about it exactly yeah it's different 997 00:34:50,990 --> 00:34:49,800 every time and we were like we were 998 00:34:52,069 --> 00:34:51,000 saying we were noticing the settings of 999 00:34:53,389 --> 00:34:52,079 people's cameras kind of changing here 1000 00:34:54,589 --> 00:34:53,399 to capture that Darkness it was really 1001 00:34:56,629 --> 00:34:54,599 Stark I mean there's parts that were 1002 00:34:59,870 --> 00:34:56,639 just completely blown out just to really 1003 00:35:01,790 --> 00:34:59,880 capture you know the darkness right 1004 00:35:02,810 --> 00:35:01,800 and so let's check back on that room and 1005 00:35:04,550 --> 00:35:02,820 see if they've kind of pulled this up 1006 00:35:05,750 --> 00:35:04,560 again still looks a little bit cloudy 1007 00:35:07,790 --> 00:35:05,760 here but we're back to the Morocco one 1008 00:35:09,170 --> 00:35:07,800 here which this has been kind of the the 1009 00:35:10,609 --> 00:35:09,180 winner of the night for me I've I've 1010 00:35:12,710 --> 00:35:10,619 really love this view that it really has 1011 00:35:14,569 --> 00:35:12,720 really beautiful weather yeah um Taiko 1012 00:35:17,089 --> 00:35:14,579 is very visible right here um this is a 1013 00:35:18,410 --> 00:35:17,099 crater this is a young crater um in the 1014 00:35:21,290 --> 00:35:18,420 southern hemisphere of the Moon and you 1015 00:35:23,690 --> 00:35:21,300 can see the Rays in full moon but during 1016 00:35:25,250 --> 00:35:23,700 a total eclipse they look even more 1017 00:35:27,589 --> 00:35:25,260 spectacular I think 1018 00:35:30,050 --> 00:35:27,599 so a question on Twitter which is kind 1019 00:35:33,230 --> 00:35:30,060 of a tricky question here so Abby asks 1020 00:35:34,310 --> 00:35:33,240 what's the rarest moon event that's the 1021 00:35:35,990 --> 00:35:34,320 kind of thing that you want to go back 1022 00:35:38,569 --> 00:35:36,000 in the almanac and sort of check through 1023 00:35:39,890 --> 00:35:38,579 it um but a kind of unusual thing 1024 00:35:42,890 --> 00:35:39,900 happened just six months ago the 1025 00:35:45,170 --> 00:35:42,900 November Eclipse was a 99 partial oh wow 1026 00:35:47,150 --> 00:35:45,180 it was so close yeah um just edging it 1027 00:35:48,950 --> 00:35:47,160 there just getting over to the edge so 1028 00:35:51,770 --> 00:35:48,960 it would have looked like this but with 1029 00:35:53,390 --> 00:35:51,780 a bright sort of limb there and it never 1030 00:35:55,069 --> 00:35:53,400 quite made it into the shadow that's 1031 00:35:57,230 --> 00:35:55,079 pretty unusual 1032 00:35:59,569 --> 00:35:57,240 um you know certain solar eclipses are 1033 00:36:01,130 --> 00:35:59,579 unusual too but to really answer that 1034 00:36:03,530 --> 00:36:01,140 question we'd have to go back to the 1035 00:36:06,230 --> 00:36:03,540 records and and find out what the 1036 00:36:07,730 --> 00:36:06,240 craziest thing was yeah yeah one more 1037 00:36:09,710 --> 00:36:07,740 question here from from Twitter as well 1038 00:36:11,690 --> 00:36:09,720 here Amber asks have there ever been 1039 00:36:14,329 --> 00:36:11,700 both solar and lunar eclipses in the 1040 00:36:16,430 --> 00:36:14,339 same year yes absolutely in fact that's 1041 00:36:19,250 --> 00:36:16,440 not uncommon at all 1042 00:36:22,190 --> 00:36:19,260 um the every six months is actually uh 1043 00:36:24,349 --> 00:36:22,200 when we're in Eclipse seasons and so 1044 00:36:26,450 --> 00:36:24,359 both solar and lunar eclipses can happen 1045 00:36:28,730 --> 00:36:26,460 there was a partial solar eclipse just 1046 00:36:30,470 --> 00:36:28,740 two weeks ago okay and that was visible 1047 00:36:33,290 --> 00:36:30,480 in the southern hemisphere if I remember 1048 00:36:35,750 --> 00:36:33,300 correctly but 1049 00:36:37,310 --> 00:36:35,760 That's Not Unusual at all in fact it's 1050 00:36:39,170 --> 00:36:37,320 very common to have them paired together 1051 00:36:41,329 --> 00:36:39,180 so solar eclipse either two weeks before 1052 00:36:42,589 --> 00:36:41,339 or two weeks after a total lunar eclipse 1053 00:36:43,670 --> 00:36:42,599 and we've been talking about the moon 1054 00:36:45,410 --> 00:36:43,680 quite a bit obviously throughout the 1055 00:36:46,730 --> 00:36:45,420 night here but let's learn a bit more 1056 00:36:48,950 --> 00:36:46,740 about why we're going to be going back 1057 00:36:51,550 --> 00:36:48,960 to the Moon just to study so much more 1058 00:36:58,670 --> 00:36:55,089 we are going 1059 00:37:01,490 --> 00:36:58,680 the history of this agency is marked 1060 00:37:02,829 --> 00:37:01,500 with broken barriers once viewed as 1061 00:37:07,010 --> 00:37:02,839 impossible 1062 00:37:09,950 --> 00:37:07,020 with science fiction turned reality with 1063 00:37:11,990 --> 00:37:09,960 innovations that have spun Industries 1064 00:37:16,730 --> 00:37:12,000 all their own 1065 00:37:19,670 --> 00:37:16,740 and with demonstrations of Peace for all 1066 00:37:27,829 --> 00:37:24,470 we soar in the skies of our home planet 1067 00:37:31,310 --> 00:37:27,839 we maintain a human presence just 1068 00:37:35,270 --> 00:37:31,320 outside of gravity and we touch points 1069 00:37:37,490 --> 00:37:35,280 all across the solar system and beyond 1070 00:37:39,970 --> 00:37:37,500 we're going back to the Moon 1071 00:37:42,650 --> 00:37:39,980 if this is why 1072 00:37:45,470 --> 00:37:42,660 the Moon is a treasure Trove of science 1073 00:37:48,230 --> 00:37:45,480 it holds opportunities for us to make 1074 00:37:51,349 --> 00:37:48,240 discoveries about our home planet about 1075 00:37:52,849 --> 00:37:51,359 our sun and a better solar system the 1076 00:37:55,069 --> 00:37:52,859 wealth of knowledge that he gleaned from 1077 00:37:58,430 --> 00:37:55,079 the moon will inspire a new generation 1078 00:38:00,710 --> 00:37:58,440 of thought and action without fail every 1079 00:38:03,050 --> 00:38:00,720 major program and mission NASA has 1080 00:38:04,790 --> 00:38:03,060 invested in has led to Technologies and 1081 00:38:07,130 --> 00:38:04,800 capabilities that have shaped our 1082 00:38:09,950 --> 00:38:07,140 culture the breakthroughs of the Artemis 1083 00:38:11,569 --> 00:38:09,960 era will Define Our Generation and the 1084 00:38:14,089 --> 00:38:11,579 generations to follow 1085 00:38:16,430 --> 00:38:14,099 the tens of thousands of jobs associated 1086 00:38:18,530 --> 00:38:16,440 with propelling us to the Moon today are 1087 00:38:20,990 --> 00:38:18,540 just the beginning of a lunar economy 1088 00:38:23,990 --> 00:38:21,000 that will see hundreds of thousands of 1089 00:38:26,030 --> 00:38:24,000 new jobs developed around the world this 1090 00:38:28,609 --> 00:38:26,040 is not an ambition of one entity or one 1091 00:38:31,609 --> 00:38:28,619 country the exploration of the moon is a 1092 00:38:33,829 --> 00:38:31,619 shared effort woven together by a desire 1093 00:38:36,650 --> 00:38:33,839 for the greater good why the moon 1094 00:38:38,990 --> 00:38:36,660 because the missions of Tomorrow Will Be 1095 00:38:41,810 --> 00:38:39,000 sparked by the accomplishments of the 1096 00:38:45,170 --> 00:38:41,820 Artemis generation today because the 1097 00:38:47,150 --> 00:38:45,180 ambition to go has already begun and 1098 00:38:48,589 --> 00:38:47,160 because Mars is calling we need to learn 1099 00:38:51,470 --> 00:38:48,599 what it takes to establish a community 1100 00:38:54,650 --> 00:38:51,480 on another Cosmic Shore so let's Camp 1101 00:38:58,430 --> 00:38:54,660 close before pushing out 1102 00:39:02,150 --> 00:38:58,440 and so we go to the moon now not as a 1103 00:39:08,690 --> 00:39:05,329 but to build a community on and around 1104 00:39:15,829 --> 00:39:08,700 the Moon capable of proving how to live 1105 00:39:21,050 --> 00:39:17,810 we'll use some lessons for more than 50 1106 00:39:23,089 --> 00:39:21,060 years of peaceful exploration to send a 1107 00:39:25,430 --> 00:39:23,099 new generation to the lunar surface to 1108 00:39:27,290 --> 00:39:25,440 stay we will anchor our efforts on the 1109 00:39:29,450 --> 00:39:27,300 lunar South Pole to establish the 1110 00:39:32,210 --> 00:39:29,460 artemis-based camp positioning us for 1111 00:39:34,730 --> 00:39:32,220 long-term science and exploration of the 1112 00:39:37,430 --> 00:39:34,740 lunar surface we will prove what it 1113 00:39:40,370 --> 00:39:37,440 takes to assemble a complex ship in deep 1114 00:39:42,770 --> 00:39:40,380 space we will perfect descending the 1115 00:39:45,410 --> 00:39:42,780 option and returning from a distance 1116 00:39:47,990 --> 00:39:45,420 service we will learn how humans can 1117 00:39:49,310 --> 00:39:48,000 survive and thrive in a partial gravity 1118 00:39:51,170 --> 00:39:49,320 environment 1119 00:39:53,510 --> 00:39:51,180 improve spacesuit designs mobile 1120 00:39:57,230 --> 00:39:53,520 habitats and with reconnaissance robots 1121 00:39:59,510 --> 00:39:57,240 pre-positioning and relocating supplies 1122 00:40:01,730 --> 00:39:59,520 the resources we find on this other 1123 00:40:04,190 --> 00:40:01,740 worlds starting with finding water reps 1124 00:40:06,410 --> 00:40:04,200 and purifying it to drinkable water and 1125 00:40:07,730 --> 00:40:06,420 find that into hydrogen fulfilled and 1126 00:40:10,609 --> 00:40:07,740 oxygen degree 1127 00:40:13,130 --> 00:40:10,619 we will establish fission power plants 1128 00:40:14,870 --> 00:40:13,140 on the surface of the Moon capable of 1129 00:40:17,690 --> 00:40:14,880 supporting a growing community of 1130 00:40:19,910 --> 00:40:17,700 efforts and we will expand the logistics 1131 00:40:22,430 --> 00:40:19,920 supply chain to enable commercial and 1132 00:40:26,630 --> 00:40:22,440 international Partners to resupply and 1133 00:40:28,970 --> 00:40:26,640 refuel deep space outposts 1134 00:40:36,849 --> 00:40:28,980 none of this is 1135 00:40:42,410 --> 00:40:40,130 again thanks a lot this kind of 1136 00:40:45,410 --> 00:40:42,420 continuous lunar presence is a natural 1137 00:40:47,230 --> 00:40:45,420 extension of all that we've learned in 1138 00:40:50,510 --> 00:40:47,240 low earth orbit 1139 00:40:53,270 --> 00:40:50,520 and what we will accomplish there will 1140 00:40:56,150 --> 00:40:53,280 ensure the Monumental missions to Mars 1141 00:40:59,270 --> 00:40:56,160 are within reach 1142 00:41:01,069 --> 00:40:59,280 as we ready the launch of the first 1143 00:41:03,410 --> 00:41:01,079 Artemis mission 1144 00:41:06,109 --> 00:41:03,420 and as commercial companies ready their 1145 00:41:08,089 --> 00:41:06,119 lunar Landers for the first private 1146 00:41:13,130 --> 00:41:08,099 payload deliveries 1147 00:41:16,720 --> 00:41:13,140 we have already begun to take the next 1148 00:41:16,730 --> 00:41:26,210 [Music] 1149 00:41:31,490 --> 00:41:28,910 hello so we just had a look at all the 1150 00:41:33,230 --> 00:41:31,500 feeds and the total lunar eclipse looks 1151 00:41:35,930 --> 00:41:33,240 absolutely stunning what did you guys 1152 00:41:38,390 --> 00:41:35,940 think it was amazing I guess oh I think 1153 00:41:40,490 --> 00:41:38,400 when I first saw Morocco the defeats 1154 00:41:42,650 --> 00:41:40,500 coming into Morocco I was like okay this 1155 00:41:44,809 --> 00:41:42,660 is the winner for today but you just 1156 00:41:46,069 --> 00:41:44,819 showed me another image from Rome and 1157 00:41:49,010 --> 00:41:46,079 they just changed my mind and that's 1158 00:41:50,390 --> 00:41:49,020 like really a reddish nice Hue across 1159 00:41:51,710 --> 00:41:50,400 the entire Moon and such beautiful 1160 00:41:53,210 --> 00:41:51,720 images 1161 00:41:56,450 --> 00:41:53,220 yeah so we have a lot of questions 1162 00:41:58,250 --> 00:41:56,460 online so let's dig in 1163 00:42:00,290 --> 00:41:58,260 um let's see so we have a viewer who 1164 00:42:02,569 --> 00:42:00,300 asks what kind of new and better 1165 00:42:04,730 --> 00:42:02,579 equipment do you need to have to return 1166 00:42:06,290 --> 00:42:04,740 to the moon and when will astronauts 1167 00:42:08,690 --> 00:42:06,300 arrive on it 1168 00:42:11,150 --> 00:42:08,700 yeah there's um a lot of different and 1169 00:42:12,829 --> 00:42:11,160 new equipment or improved equipment that 1170 00:42:14,150 --> 00:42:12,839 we're looking at for the moon 1171 00:42:15,890 --> 00:42:14,160 um one of which I think I've mentioned a 1172 00:42:17,390 --> 00:42:15,900 few times is that we're looking at using 1173 00:42:19,550 --> 00:42:17,400 the resources that are on the moon we 1174 00:42:21,470 --> 00:42:19,560 haven't done this before so all sorts of 1175 00:42:24,109 --> 00:42:21,480 new technologies whether it's drills or 1176 00:42:25,790 --> 00:42:24,119 just systems that can extract oxygen and 1177 00:42:28,010 --> 00:42:25,800 water and things from the from the lunar 1178 00:42:29,089 --> 00:42:28,020 regulator these are all new systems uh 1179 00:42:30,410 --> 00:42:29,099 we're improving things like our 1180 00:42:31,849 --> 00:42:30,420 Precision Landing you know how 1181 00:42:33,050 --> 00:42:31,859 accurately can you land where you want 1182 00:42:34,730 --> 00:42:33,060 to land 1183 00:42:37,010 --> 00:42:34,740 um and how how well can you avoid 1184 00:42:38,270 --> 00:42:37,020 obstacles like craters and boulders and 1185 00:42:39,650 --> 00:42:38,280 things um so those are some things 1186 00:42:41,750 --> 00:42:39,660 really The Landing but yeah different 1187 00:42:44,089 --> 00:42:41,760 sampling techniques for the astronauts 1188 00:42:45,770 --> 00:42:44,099 all sorts of new technologies um which 1189 00:42:47,870 --> 00:42:45,780 is really exciting because these will be 1190 00:42:48,950 --> 00:42:47,880 useful for Mars and also for our lives 1191 00:42:50,510 --> 00:42:48,960 on Earth 1192 00:42:52,430 --> 00:42:50,520 um as far as when they're getting there 1193 00:42:53,690 --> 00:42:52,440 um NASA's targeting 2025 for our first 1194 00:42:55,730 --> 00:42:53,700 grouped mission 1195 00:42:58,190 --> 00:42:55,740 and so you mentioned it will be useful 1196 00:43:00,530 --> 00:42:58,200 for us on Earth um could you tell us 1197 00:43:01,970 --> 00:43:00,540 more yeah um I mean I don't have a lot 1198 00:43:03,470 --> 00:43:01,980 of specific examples off the top of my 1199 00:43:04,970 --> 00:43:03,480 head but um you know for the Apollo 1200 00:43:06,710 --> 00:43:04,980 program for example we call them 1201 00:43:08,510 --> 00:43:06,720 spin-offs or all these technologies that 1202 00:43:10,069 --> 00:43:08,520 NASA developed for the the lunar program 1203 00:43:11,210 --> 00:43:10,079 uh that then became useful and 1204 00:43:13,130 --> 00:43:11,220 everything tennis shoes are a good 1205 00:43:14,630 --> 00:43:13,140 example of one I don't know if you have 1206 00:43:16,550 --> 00:43:14,640 any other examples you can think of off 1207 00:43:18,890 --> 00:43:16,560 the top of your head something right now 1208 00:43:21,230 --> 00:43:18,900 but yeah I think so 1209 00:43:23,270 --> 00:43:21,240 um I think the the Tamil blankets that 1210 00:43:25,609 --> 00:43:23,280 were used first the entire during the 1211 00:43:28,069 --> 00:43:25,619 Apollo space program and the spaceways 1212 00:43:30,109 --> 00:43:28,079 are being heavily used on Earth for a 1213 00:43:33,050 --> 00:43:30,119 variety of purposes 1214 00:43:34,910 --> 00:43:33,060 um and even these retro reflectors I'm 1215 00:43:37,250 --> 00:43:34,920 sorry I keep going back to those Eternal 1216 00:43:39,829 --> 00:43:37,260 reflectors that's what I do for work 1217 00:43:42,890 --> 00:43:39,839 um so I uh you know when I explain it to 1218 00:43:45,109 --> 00:43:42,900 some like a child what do I do I I I 1219 00:43:47,809 --> 00:43:45,119 make them look at you know all these uh 1220 00:43:49,970 --> 00:43:47,819 you know on the road as you travel when 1221 00:43:52,010 --> 00:43:49,980 you shine your headlight at them it 1222 00:43:53,690 --> 00:43:52,020 comes back right at you and those those 1223 00:43:55,430 --> 00:43:53,700 are Miniature versions of the same thing 1224 00:43:56,870 --> 00:43:55,440 but just that they're not space grade 1225 00:44:00,230 --> 00:43:56,880 right they're not ready to go to space 1226 00:44:01,849 --> 00:44:00,240 but yeah there's a whole lot of um you 1227 00:44:04,790 --> 00:44:01,859 know equipments which were developed 1228 00:44:08,510 --> 00:44:04,800 during the Space Race uh and uh you know 1229 00:44:10,970 --> 00:44:08,520 the Apollo era which uh is being used 1230 00:44:12,650 --> 00:44:10,980 right now on on Earth for to make our 1231 00:44:14,329 --> 00:44:12,660 lives better 1232 00:44:16,790 --> 00:44:14,339 fantastic so we have a question from 1233 00:44:18,470 --> 00:44:16,800 Charlie couch from YouTube and they 1234 00:44:22,069 --> 00:44:18,480 asked can you tell us the difference 1235 00:44:25,309 --> 00:44:22,079 between a solar and lunar eclipse 1236 00:44:28,550 --> 00:44:25,319 of course um so during a lunar eclipse 1237 00:44:32,150 --> 00:44:28,560 what comes between uh you know the uh 1238 00:44:33,470 --> 00:44:32,160 the Sun and the Moon is is the Earth so 1239 00:44:36,230 --> 00:44:33,480 you know dude that's what we're 1240 00:44:37,730 --> 00:44:36,240 witnessing today and similarly for the 1241 00:44:40,490 --> 00:44:37,740 solar eclipse what we have in between 1242 00:44:43,970 --> 00:44:40,500 the object in between is the moon 1243 00:44:46,849 --> 00:44:43,980 um and it's not safe to look at 1244 00:44:48,890 --> 00:44:46,859 um you know by eye uh the the solar 1245 00:44:50,390 --> 00:44:48,900 eclipse but you know it's very safe to 1246 00:44:51,770 --> 00:44:50,400 look at the moon so I encourage you all 1247 00:44:54,170 --> 00:44:51,780 to go out and look at the Moon if you 1248 00:44:55,609 --> 00:44:54,180 get a chance to yeah and what are the 1249 00:44:57,770 --> 00:44:55,619 differences when you when you look in 1250 00:44:58,849 --> 00:44:57,780 the sky because they look pretty they 1251 00:45:01,130 --> 00:44:58,859 look pretty different 1252 00:45:03,050 --> 00:45:01,140 right in in one of them you know you 1253 00:45:04,730 --> 00:45:03,060 have the sun in the background so it 1254 00:45:07,370 --> 00:45:04,740 could be a you know during the daylight 1255 00:45:10,010 --> 00:45:07,380 right and then suddenly it goes all dim 1256 00:45:12,170 --> 00:45:10,020 here on on earth when this is the solar 1257 00:45:13,069 --> 00:45:12,180 eclipse and 1258 00:45:17,569 --> 00:45:13,079 um 1259 00:45:19,849 --> 00:45:17,579 mean to have a lunar eclipse you need a 1260 00:45:22,130 --> 00:45:19,859 full moon uh right uh to get that 1261 00:45:24,170 --> 00:45:22,140 configuration for that eclipse and so 1262 00:45:25,490 --> 00:45:24,180 these are typically visible at night so 1263 00:45:26,870 --> 00:45:25,500 that's one of the differences I can 1264 00:45:29,510 --> 00:45:26,880 think of 1265 00:45:32,510 --> 00:45:29,520 okay so we have a question from Jack 1266 00:45:34,670 --> 00:45:32,520 and he asks how much do we know about 1267 00:45:37,190 --> 00:45:34,680 The Far Side of the Moon mapping 1268 00:45:39,050 --> 00:45:37,200 geography Etc has a satellite sustained 1269 00:45:41,089 --> 00:45:39,060 a durable orbit around the moon in order 1270 00:45:42,170 --> 00:45:41,099 to map the surface and has that ever 1271 00:45:44,690 --> 00:45:42,180 been done 1272 00:45:46,430 --> 00:45:44,700 uh yes great question uh so yes um 1273 00:45:49,130 --> 00:45:46,440 Apollo obviously that those were all 1274 00:45:50,630 --> 00:45:49,140 near side missions but we do know a lot 1275 00:45:52,730 --> 00:45:50,640 about the far side as well we have the 1276 00:45:54,530 --> 00:45:52,740 lunar reconnaissance Orbiter lro has 1277 00:45:55,790 --> 00:45:54,540 been orbiting the moon for almost 13 1278 00:45:57,050 --> 00:45:55,800 years now 1279 00:45:58,490 --> 00:45:57,060 um and yeah doing a lot of the mapping 1280 00:46:00,710 --> 00:45:58,500 that was that was asked about mapping 1281 00:46:03,109 --> 00:46:00,720 topography we had Grail that mapped the 1282 00:46:04,670 --> 00:46:03,119 gravity data of the moon so we don't 1283 00:46:06,770 --> 00:46:04,680 have you know we haven't had any surface 1284 00:46:07,910 --> 00:46:06,780 missions from the US to The Far Side of 1285 00:46:09,530 --> 00:46:07,920 the Moon we haven't returned those 1286 00:46:11,089 --> 00:46:09,540 samples we have a lot of really great 1287 00:46:12,950 --> 00:46:11,099 orbital instruments that tell us things 1288 00:46:14,750 --> 00:46:12,960 about about the composition and the 1289 00:46:16,190 --> 00:46:14,760 again the topography we know that 1290 00:46:18,589 --> 00:46:16,200 there's not as many 1291 00:46:21,050 --> 00:46:18,599 um uh volcanic areas on The Far Side of 1292 00:46:22,130 --> 00:46:21,060 the Moon we know the crust is thicker uh 1293 00:46:23,450 --> 00:46:22,140 I think the composition is a bit 1294 00:46:25,490 --> 00:46:23,460 different but we don't really know why 1295 00:46:28,609 --> 00:46:25,500 so there's a lot of good reasons to go 1296 00:46:32,270 --> 00:46:28,619 go explore the far side as well 1297 00:46:34,910 --> 00:46:32,280 okay and so Kelsey on Twitter asks my 1298 00:46:36,770 --> 00:46:34,920 eight-year-old Nico is asking when is 1299 00:46:39,829 --> 00:46:36,780 the Artemis Mission going to the moon 1300 00:46:40,970 --> 00:46:39,839 great question Nico yeah so like depends 1301 00:46:42,530 --> 00:46:40,980 on which art in this Mission you're 1302 00:46:45,109 --> 00:46:42,540 talking about we'll have our our 1303 00:46:46,910 --> 00:46:45,119 uncrewed demo um this year uh and then 1304 00:46:50,030 --> 00:46:46,920 our our first astronauts will hopefully 1305 00:46:52,730 --> 00:46:50,040 be on the surface in 2025. 1306 00:46:54,410 --> 00:46:52,740 okay so our next question is from 1307 00:46:56,750 --> 00:46:54,420 Tiffany on Twitter 1308 00:47:01,130 --> 00:46:56,760 and they asked what is the Moon's core 1309 00:47:04,609 --> 00:47:01,140 made of oh so 1310 00:47:06,410 --> 00:47:04,619 um you know the moon score so if you it 1311 00:47:10,309 --> 00:47:06,420 depends on how deep you're going right 1312 00:47:13,550 --> 00:47:10,319 so we know from uh initially from again 1313 00:47:16,309 --> 00:47:13,560 lunar laser ranging data uh by looking 1314 00:47:18,650 --> 00:47:16,319 at orientation in space we kind of 1315 00:47:20,390 --> 00:47:18,660 figured out uh by you know monitoring 1316 00:47:22,849 --> 00:47:20,400 these retro reflectors we have about 1317 00:47:24,589 --> 00:47:22,859 five of them we've been monitoring them 1318 00:47:27,710 --> 00:47:24,599 very closely over a long period of time 1319 00:47:29,750 --> 00:47:27,720 and we were able to you know reconstruct 1320 00:47:31,730 --> 00:47:29,760 the orientation of the Moon predict it 1321 00:47:34,630 --> 00:47:31,740 and compare with observations so when 1322 00:47:37,670 --> 00:47:34,640 you stick in a liquid core in that model 1323 00:47:40,069 --> 00:47:37,680 it it very well agrees with the data set 1324 00:47:41,990 --> 00:47:40,079 and this is one of the 1325 00:47:43,549 --> 00:47:42,000 um you know findings from lunar 1326 00:47:45,770 --> 00:47:43,559 initially from the lunar laser ranging 1327 00:47:48,770 --> 00:47:45,780 data but it was also later confirmed by 1328 00:47:51,470 --> 00:47:48,780 you know re-analysis of seismic data 1329 00:47:52,609 --> 00:47:51,480 that was collected from the Apollo 1330 00:47:55,970 --> 00:47:52,619 Mission 1331 00:47:58,790 --> 00:47:55,980 um so indeed it's made out of a liquid 1332 00:48:01,490 --> 00:47:58,800 core but there is a 1333 00:48:04,670 --> 00:48:01,500 um an expectation that there could 1334 00:48:07,490 --> 00:48:04,680 potentially be also a solid inner core 1335 00:48:11,450 --> 00:48:07,500 within that liquid core just like for 1336 00:48:15,109 --> 00:48:11,460 the Earth and this is a currently you 1337 00:48:17,809 --> 00:48:15,119 know uh in research and we still don't 1338 00:48:20,390 --> 00:48:17,819 have a very strong evidence 1339 00:48:23,809 --> 00:48:20,400 um uh suggesting that the moon has a 1340 00:48:25,730 --> 00:48:23,819 solid core but some of the samples that 1341 00:48:27,890 --> 00:48:25,740 were returned from you know the moon 1342 00:48:30,910 --> 00:48:27,900 during the Apollo missions 1343 00:48:33,890 --> 00:48:30,920 um they had Remnant magnetism in them 1344 00:48:36,349 --> 00:48:33,900 and you know those are signs that at 1345 00:48:39,770 --> 00:48:36,359 some point in time the moon had you know 1346 00:48:41,990 --> 00:48:39,780 an active magnetic field and so that 1347 00:48:43,790 --> 00:48:42,000 potentially magnetized these rocks that 1348 00:48:45,950 --> 00:48:43,800 were returned but currently we know that 1349 00:48:48,950 --> 00:48:45,960 there's no magnetization uh you know 1350 00:48:51,290 --> 00:48:48,960 there's no active magnetic field so you 1351 00:48:53,950 --> 00:48:51,300 know it's uh which suggests that there's 1352 00:48:56,650 --> 00:48:53,960 a potentially as maybe a very small 1353 00:49:00,589 --> 00:48:56,660 solid intercore which is you know 1354 00:49:03,170 --> 00:49:00,599 so it it's definitely an active topic of 1355 00:49:04,970 --> 00:49:03,180 research and we are seeking answers to 1356 00:49:08,089 --> 00:49:04,980 this via you know several of those 1357 00:49:10,790 --> 00:49:08,099 missions that Ryan was talking about so 1358 00:49:13,130 --> 00:49:10,800 yeah it's we know for sure there's a 1359 00:49:15,829 --> 00:49:13,140 liquid core but a solid core 1360 00:49:17,329 --> 00:49:15,839 I I my bed is indeed there is but you 1361 00:49:19,490 --> 00:49:17,339 know we want evidence for It We Are 1362 00:49:21,290 --> 00:49:19,500 Scientists so we want evidence 1363 00:49:22,910 --> 00:49:21,300 that's fascinating so we have a lot more 1364 00:49:25,370 --> 00:49:22,920 questions to get to later on in the show 1365 00:49:27,589 --> 00:49:25,380 but let's go back to James and Ernie 1366 00:49:30,710 --> 00:49:27,599 right now to see what the lunar eclipse 1367 00:49:32,329 --> 00:49:30,720 intertality looks like around the world 1368 00:49:33,770 --> 00:49:32,339 yeah thanks so much Joey we were just 1369 00:49:35,809 --> 00:49:33,780 looking at a feed from Nebraska a second 1370 00:49:37,970 --> 00:49:35,819 ago just switched off but they had the 1371 00:49:39,770 --> 00:49:37,980 most red looking Moon it was incredible 1372 00:49:41,089 --> 00:49:39,780 it was beautiful wasn't it yeah we were 1373 00:49:42,290 --> 00:49:41,099 tracking this earlier the weather looked 1374 00:49:43,970 --> 00:49:42,300 really nice from Nebraska so they must 1375 00:49:45,829 --> 00:49:43,980 have had a beautiful clear night there 1376 00:49:47,390 --> 00:49:45,839 yeah in fact I was saying earlier 1377 00:49:48,530 --> 00:49:47,400 tonight that that's that's the clear 1378 00:49:50,390 --> 00:49:48,540 part of the country that's the part 1379 00:49:51,770 --> 00:49:50,400 that's not affected by clouds and and it 1380 00:49:54,170 --> 00:49:51,780 turned out somebody was there watching 1381 00:49:55,549 --> 00:49:54,180 this amazing yeah and so a couple 1382 00:49:56,930 --> 00:49:55,559 questions have come in on Twitter as 1383 00:49:58,970 --> 00:49:56,940 well here too and I think you can really 1384 00:50:01,370 --> 00:49:58,980 speak to these very well Karthik asks 1385 00:50:03,470 --> 00:50:01,380 why do lunar eclipses happen rarely and 1386 00:50:05,030 --> 00:50:03,480 not every 28 days right that's a great 1387 00:50:07,730 --> 00:50:05,040 question and it's because the moon's 1388 00:50:09,410 --> 00:50:07,740 orbit is slightly tilted so 1389 00:50:10,970 --> 00:50:09,420 um five out of the six months the moon 1390 00:50:14,270 --> 00:50:10,980 is going to pass either underneath the 1391 00:50:16,190 --> 00:50:14,280 Shadow or above it uh it's only when you 1392 00:50:18,049 --> 00:50:16,200 get that tilt oriented just right so 1393 00:50:20,750 --> 00:50:18,059 that the moon is going 1394 00:50:23,089 --> 00:50:20,760 um right along that line that connects 1395 00:50:24,849 --> 00:50:23,099 the Earth and the Sun that you get lunar 1396 00:50:28,069 --> 00:50:24,859 eclipses and solar eclipses as well 1397 00:50:29,569 --> 00:50:28,079 those are related so a lunar eclipse is 1398 00:50:30,650 --> 00:50:29,579 always the full moon solar eclipse is 1399 00:50:32,750 --> 00:50:30,660 always the new moon so they're at 1400 00:50:34,370 --> 00:50:32,760 opposite ends of the orbit but that's 1401 00:50:36,890 --> 00:50:34,380 what Eclipse season really means it's 1402 00:50:38,510 --> 00:50:36,900 when that tilt is oriented in such a way 1403 00:50:40,730 --> 00:50:38,520 that it's sort of Crossing through the 1404 00:50:42,530 --> 00:50:40,740 center line got it amazing and you know 1405 00:50:44,329 --> 00:50:42,540 if you're just tuning in too this is 1406 00:50:46,250 --> 00:50:44,339 really going on quite a bit longer after 1407 00:50:48,049 --> 00:50:46,260 our broadcast here as well too so you 1408 00:50:49,309 --> 00:50:48,059 know stick around put on another pot of 1409 00:50:50,870 --> 00:50:49,319 coffee if it's getting late for you 1410 00:50:52,790 --> 00:50:50,880 wherever you are in the world and just 1411 00:50:55,069 --> 00:50:52,800 take your time to observe and really 1412 00:50:57,589 --> 00:50:55,079 enjoy this view here too another 1413 00:50:59,569 --> 00:50:57,599 question from Twitter from Lucas he asks 1414 00:51:01,370 --> 00:50:59,579 how do you calculate the next lunar 1415 00:51:02,930 --> 00:51:01,380 eclipse or any eclipse for that matter 1416 00:51:06,049 --> 00:51:02,940 so 1417 00:51:07,690 --> 00:51:06,059 gotten very good at 1418 00:51:10,490 --> 00:51:07,700 um the the 1419 00:51:12,410 --> 00:51:10,500 calculation of the position of the Moon 1420 00:51:13,970 --> 00:51:12,420 the Earth and the Sun and these are the 1421 00:51:15,530 --> 00:51:13,980 critical elements that you need in order 1422 00:51:18,589 --> 00:51:15,540 to understand when an eclipse is going 1423 00:51:21,470 --> 00:51:18,599 to happen we can predict those 100 100 1424 00:51:23,210 --> 00:51:21,480 or more years into the future and what 1425 00:51:24,230 --> 00:51:23,220 you need to do is just roll that clock 1426 00:51:25,549 --> 00:51:24,240 forward while you're doing the 1427 00:51:27,829 --> 00:51:25,559 calculation and find out where 1428 00:51:30,349 --> 00:51:27,839 everything lines up again and that's 1429 00:51:33,410 --> 00:51:30,359 basically how you do it uh 1430 00:51:36,650 --> 00:51:33,420 a little bit dark here San Diego oh 1431 00:51:38,990 --> 00:51:36,660 there's the fee this is the one up yeah 1432 00:51:40,370 --> 00:51:39,000 this is an absolutely stunning view out 1433 00:51:42,109 --> 00:51:40,380 in the plains of Nebraska a gorgeous 1434 00:51:43,970 --> 00:51:42,119 gorgeous shot here of the moon really 1435 00:51:45,770 --> 00:51:43,980 love this one as well and so 1436 00:51:48,109 --> 00:51:45,780 unfortunately here it stayed cloudy for 1437 00:51:50,329 --> 00:51:48,119 us a lot of thunderstorms but I was 1438 00:51:52,069 --> 00:51:50,339 actually able to visit the Moon from our 1439 00:51:53,990 --> 00:51:52,079 own Goddard Visitor Center it was a lot 1440 00:51:56,030 --> 00:51:54,000 of fun you know we got a nice close-up 1441 00:51:57,829 --> 00:51:56,040 view of it here hoping for a bit better 1442 00:51:59,390 --> 00:51:57,839 weather you know for the next lunar 1443 00:52:01,490 --> 00:51:59,400 eclipse down the line here as well so 1444 00:52:04,210 --> 00:52:01,500 we'll see how that goes as well uh Joy 1445 00:52:07,730 --> 00:52:04,220 how was your trip up the space today 1446 00:52:10,430 --> 00:52:07,740 yes I highly recommend going to NASA's 1447 00:52:12,890 --> 00:52:10,440 Visitor Center in Greenback Maryland to 1448 00:52:15,049 --> 00:52:12,900 go to the Moon yourself as well so we 1449 00:52:18,829 --> 00:52:15,059 have a lot more questions from social 1450 00:52:21,770 --> 00:52:18,839 media so let's let's get chatting 1451 00:52:24,650 --> 00:52:21,780 um we have a question from TJ on Twitter 1452 00:52:27,170 --> 00:52:24,660 and they ask why do we have to wear 1453 00:52:30,770 --> 00:52:27,180 special glasses during a solar eclipse 1454 00:52:35,030 --> 00:52:30,780 but not during a lunar eclipse 1455 00:52:36,829 --> 00:52:35,040 well um you know the solar eclipse in 1456 00:52:38,990 --> 00:52:36,839 during solar eclipse looking at you know 1457 00:52:40,910 --> 00:52:39,000 the sun and the sky and you really you 1458 00:52:43,430 --> 00:52:40,920 don't want to look at the sun directly 1459 00:52:46,010 --> 00:52:43,440 because of all the harmful radiation 1460 00:52:47,690 --> 00:52:46,020 such as like UV light Etc that's coming 1461 00:52:50,450 --> 00:52:47,700 in at all times you should never look at 1462 00:52:51,890 --> 00:52:50,460 the sun right so even during the solar 1463 00:52:55,010 --> 00:52:51,900 eclipse what happens is you know you get 1464 00:52:56,569 --> 00:52:55,020 that really drop in uh you know sunlight 1465 00:52:59,750 --> 00:52:56,579 and so you have 1466 00:53:01,910 --> 00:52:59,760 um you have a very really dark place and 1467 00:53:04,910 --> 00:53:01,920 suddenly when the moon 1468 00:53:06,770 --> 00:53:04,920 um you know moves away uh you get this 1469 00:53:08,930 --> 00:53:06,780 Saturn bright so which can damage your 1470 00:53:13,670 --> 00:53:08,940 eye so that's why they recommend you to 1471 00:53:15,770 --> 00:53:13,680 wear a filter whereas for the lunar 1472 00:53:17,870 --> 00:53:15,780 eclipse you're looking at 1473 00:53:21,430 --> 00:53:17,880 um just like looking at a moon during a 1474 00:53:24,170 --> 00:53:21,440 full moon or a a waiting or a you know 1475 00:53:26,630 --> 00:53:24,180 during the other phases of the moon uh 1476 00:53:28,790 --> 00:53:26,640 is that is the the light which is 1477 00:53:31,970 --> 00:53:28,800 bounced off from the Sun and then coming 1478 00:53:34,130 --> 00:53:31,980 to you so that's much less bright and 1479 00:53:38,030 --> 00:53:34,140 you know they're not as harmful as that 1480 00:53:41,030 --> 00:53:38,040 looking at the solar eclipse 1481 00:53:44,089 --> 00:53:41,040 so we have a question from nip per on 1482 00:53:46,130 --> 00:53:44,099 NASA Moon Facebook and they ask with the 1483 00:53:49,250 --> 00:53:46,140 moon receding from the earth about two 1484 00:53:52,549 --> 00:53:49,260 centimeters per year how long will it be 1485 00:53:54,890 --> 00:53:52,559 until there will be no total eclipses or 1486 00:53:57,190 --> 00:53:54,900 by Mega coincidence will the sun shrink 1487 00:53:59,870 --> 00:53:57,200 at the same ratio 1488 00:54:01,370 --> 00:53:59,880 really great question and I don't know 1489 00:54:02,829 --> 00:54:01,380 that I know the answer can we shout that 1490 00:54:06,170 --> 00:54:02,839 one over to Ernie 1491 00:54:08,210 --> 00:54:06,180 I think uh I mean it's we can make that 1492 00:54:10,430 --> 00:54:08,220 calculation uh because you know we have 1493 00:54:13,010 --> 00:54:10,440 the models that can extrapolate it based 1494 00:54:16,670 --> 00:54:13,020 on the current data sets that we have to 1495 00:54:19,430 --> 00:54:16,680 the Future uh but you know at some point 1496 00:54:20,829 --> 00:54:19,440 we we're not going to be able to witness 1497 00:54:25,010 --> 00:54:20,839 like 1498 00:54:27,290 --> 00:54:25,020 a total uh you know solar eclipse either 1499 00:54:29,030 --> 00:54:27,300 because you know we'll we'll have the 1500 00:54:31,190 --> 00:54:29,040 moon becoming smaller and small as it 1501 00:54:32,510 --> 00:54:31,200 goes away but it's a calculation that 1502 00:54:35,710 --> 00:54:32,520 needs to be done before it can be 1503 00:54:39,109 --> 00:54:35,720 answered it won't be in our lifetimes 1504 00:54:42,589 --> 00:54:39,119 okay so we have another question 1505 00:54:44,690 --> 00:54:42,599 um marisota electronic on YouTube asks 1506 00:54:46,970 --> 00:54:44,700 is there gravity on the moon 1507 00:54:49,190 --> 00:54:46,980 yes the gravity on the moon is one-sixth 1508 00:54:50,690 --> 00:54:49,200 that of Earth so um that's why if you 1509 00:54:51,770 --> 00:54:50,700 see videos of the Apollo Astronauts they 1510 00:54:53,329 --> 00:54:51,780 can look like they're hopping around 1511 00:54:54,770 --> 00:54:53,339 kind of almost in slow motion like 1512 00:54:57,950 --> 00:54:54,780 because there there is gravity it's just 1513 00:55:00,349 --> 00:54:57,960 not quite as quite as strong as hers 1514 00:55:02,750 --> 00:55:00,359 okay so we have um Loudoun on Twitter 1515 00:55:06,170 --> 00:55:02,760 and they ask why are lunar eclipses only 1516 00:55:10,970 --> 00:55:06,180 visible from certain locations 1517 00:55:13,849 --> 00:55:10,980 oh I think uh um so it to be in that 1518 00:55:16,250 --> 00:55:13,859 shadowed region right so um the the 1519 00:55:17,990 --> 00:55:16,260 moon's orbit is slightly inclined so 1520 00:55:20,210 --> 00:55:18,000 what happens is there are only specific 1521 00:55:22,970 --> 00:55:20,220 points in the orbit where you can have 1522 00:55:26,030 --> 00:55:22,980 that shadow so as long as uh you know 1523 00:55:28,549 --> 00:55:26,040 you the Moon is visible in the sky when 1524 00:55:30,770 --> 00:55:28,559 the moon is passing through that uh you 1525 00:55:34,250 --> 00:55:30,780 know shadow of the earth you'll be able 1526 00:55:35,990 --> 00:55:34,260 to be able to see that and that's 1527 00:55:38,870 --> 00:55:36,000 probably why 1528 00:55:41,089 --> 00:55:38,880 okay so that is all we have time for 1529 00:55:42,410 --> 00:55:41,099 today thank you both so much for 1530 00:55:45,530 --> 00:55:42,420 answering everyone's questions online 1531 00:55:47,450 --> 00:55:45,540 thanks for having us yeah pleasure and 1532 00:55:50,150 --> 00:55:47,460 thank you to everyone joining us at home 1533 00:55:53,690 --> 00:55:50,160 for this remarkable experience remember 1534 00:55:56,089 --> 00:55:53,700 totality ends at 12 54 a.m eastern time 1535 00:55:58,069 --> 00:55:56,099 so if it's not cloudy where you are I 1536 00:56:00,470 --> 00:55:58,079 recommend you head outside and check out 1537 00:56:02,710 --> 00:56:00,480 the red moon if you want to learn more 1538 00:56:04,670 --> 00:56:02,720 about the moon head to 1539 00:56:06,349 --> 00:56:04,680 moon.nasa.gov and if you want to learn 1540 00:56:09,109 --> 00:56:06,359 about NASA's latest research around the 1541 00:56:12,770 --> 00:56:09,119 Moon follow us on NASA Moon on Facebook 1542 00:56:15,370 --> 00:56:12,780 and Twitter and we will be continuing to 1543 00:56:17,510 --> 00:56:15,380 stream the lunar eclipse on 1544 00:56:19,069 --> 00:56:17,520 moon.natural.gov so head over there so 1545 00:56:21,530 --> 00:56:19,079 you can check out the lunar eclipse at 1546 00:56:23,329 --> 00:56:21,540 different locations across the world and 1547 00:56:25,670 --> 00:56:23,339 mark your calendars for the next lunar 1548 00:56:28,549 --> 00:56:25,680 eclipse which will be on November 8th 1549 00:56:31,920 --> 00:56:28,559 until then see you next time 1550 00:57:12,950 --> 00:56:45,650 [Music] 1551 00:57:12,960 --> 00:57:16,550 foreign 1552 00:58:06,670 --> 00:57:22,960 [Music] 1553 00:58:10,329 --> 00:58:06,680 [Applause] 1554 00:58:10,339
