1 00:00:08,750 --> 00:00:06,170 good afternoon and welcome to NASA 2 00:00:10,459 --> 00:00:08,760 headquarters in Washington DC i'm steve 3 00:00:12,830 --> 00:00:10,469 cole with the office of communications 4 00:00:15,560 --> 00:00:12,840 we're here today to give you a preview 5 00:00:17,960 --> 00:00:15,570 of NASA's next mission to continue our 6 00:00:21,200 --> 00:00:17,970 exploration of the solar system and 7 00:00:23,150 --> 00:00:21,210 specifically our son the mission is iris 8 00:00:25,970 --> 00:00:23,160 and it will provide the most detailed 9 00:00:28,330 --> 00:00:25,980 look ever of the sun's lower atmosphere 10 00:00:30,679 --> 00:00:28,340 a region called the interface region 11 00:00:33,410 --> 00:00:30,689 iris which stands for the interface 12 00:00:36,020 --> 00:00:33,420 region imaging spectrograph is scheduled 13 00:00:38,540 --> 00:00:36,030 to launch jun 26 from vandenberg air 14 00:00:40,670 --> 00:00:38,550 force base in california we have four 15

ask NASA we have a lot more 32 00:01:33,789 --> 00:01:30,360 information on them online as well about 33 00:01:38,179 --> 00:01:33,799 the mission and you can see that at ww 34 00:01:40,130 --> 00:01:38,189 NSA gov / iris will continue coverage of 35 00:01:43,969 --> 00:01:40,140 the mission up through launch at that 36 00:01:46,910 --> 00:01:43,979 website so to begin we'll start our 37 00:01:49,219 --> 00:01:46,920 first presentation from Jeffrey numark 38 00:01:52,280 --> 00:01:49,229 well thanks I'm thrilled to be here 39 00:01:54,289 --> 00:01:52,290 today to discuss the iris mission iris 40 00:01:56,899 --> 00:01:54,299 is our newest member of our here physics 41 00:01:59,300 --> 00:01:56,909 fleet of spacecraft I'd like to start by 42 00:02:02,149 --> 00:01:59,310 giving a little background on on what he 43 00:02:04,010 --> 00:02:02,159 of physics is both the oldest known 44 00:02:07,609 --> 00:02:04,020 science people have wondered about the 45 00:02:09,199 --> 00:02:07,619 Sun ever since we existed and and also 46 00:02:11,119 --> 00:02:09,209 we're new science trying to understand 47 00:02:13,610 --> 00:02:11,129 the Sun and its interactions with the 48 00:02:16,009 --> 00:02:13,620 earth and the solar system the 49 00:02:18,289 --> 00:02:16,019 main of heliophysics ranges from the 50 00:02:20,750 --> 00:02:18,299 interior of the Sun through its solar 51 00:02:22,309 --> 00:02:20,760 active atmosphere to the neo space 52 00:02:24,289 --> 00:02:22,319 environment of the earth and to the 53 00:02:28,820 --> 00:02:24,299 edges of our solar system far beyond 54 00:02:30,619 --> 00:02:28,830 Pluto this whole vast extended region is 55 00:02:33,199 --> 00:02:30,629 the extended atmosphere of the Sun we 56 00:02:35,509 --> 00:02:33,209 call it the heliosphere hey physics 57 00:02:38,630 --> 00:02:35,519 seeks to understand basic questions 58 00:02:41,000 --> 00:02:38,640 about this system such as what causes 59 00:02:42,979 --> 00:02:41,010 the Sun to vary how did the earth and 60 00:02:45,199 --> 00:02:42,989 neathia sphere respond what are the 61 00:02:47,449 --> 00:02:45,209 impacts humanity on the earth and to 62 00:02:50,660 --> 00:02:47,459 other worlds as we explore beyond in 63 00:02:52,460 --> 00:02:50,670 order to answer these questions we use a 64 00:02:56,180 --> 00:02:52,470 fleet of spacecraft we call the 65 00:02:57,830 --> 00:02:56,190 heliophysics system observatory our hsl 66 00:03:02,240 --> 00:02:57,840 if you can show graphic number one 67 00:03:06,199 --> 00:03:02,250 please the hso utilizes our entire fleet 68 00:03:08,990 --> 00:03:06,209 of 18 missions over 28 spacecraft as a 69 00:03:11,509 --> 00:03:09,000 distributed observatory to discover the 70 00:03:13,490 --> 00:03:11,519 multiple scales and the couple processes 71 00:03:15,050 --> 00:03:13,500 at work throughout this heliosphere and 72 00:03:17,050 --> 00:03:15,060 then through this complex system that 73 00:03:20,599 --> 00:03:17,060 make up our space environment our 74 00:03:22,580 --> 00:03:20,609 spacecraft orbit the Sun the earth the 75 00:03:26,569 --> 00:03:22,590 regions in between and out to the edge 76 00:03:28,460 --> 00:03:26,579 of the solar system iris joins us fleet 77 00:03:30,440 --> 00:03:28,470 is the newest member of our Explorer 78 00:03:33,379 --> 00:03:30,450 class of missions if you can please show 79 00:03:35,659 --> 00:03:33,389 them graphic number two the Explorer 80 00:03:38,330 --> 00:03:35,669 program is the oldest continuous program 81 00:03:40,580 --> 00:03:38,340 within NASA explorers are one of the 82 00:03:43,490 --> 00:03:40,590 three flight programs we have in here 83 00:03:45,559 --> 00:03:43,500 physics the Explorers offer world-class 84 00:03:48,860 --> 00:03:45,569 science with frequent opportunities 85 00:03:51,110 --> 00:03:48,870 relatively modest cost this brief 86 00:03:53,599 --> 00:03:51,120 montage that you're seeing here is it 87 00:03:55,819 --> 00:03:53,609 shows some examples of hit of Explorer 88 00:03:58,099 --> 00:03:55,829 missions throughout the years starting 89 00:04:00,770 --> 00:03:58,109 with Explorer 011 should in 1858 the 90 00:04:02,780 --> 00:04:00,780 very first NASA mission through some of 91 00:04:05,750 --> 00:04:02,790 the early explorers the Nobel Prize 92 00:04:08,420 --> 00:04:05,760 winning Kobe to our more recent 93 00:04:12,740 --> 00:04:08,430 heliophysics explorers like aim ressie 94 00:04:16,699 --> 00:04:12,750 ibex and of course coming up to iris our 95 00:04:18,770 --> 00:04:16,709 soon-to-be launched Explorer although we 96 00:04:21,770 --> 00:04:18,780 already have some solid servitor ease in 97 00:04:23,870 --> 00:04:21,780 our fleet iris will fool crucial gaps in 98 00:04:26,839 --> 00:04:23,880 our understanding over the role the 99 00:04:27,480 --> 00:04:26,849 interface region plays in powering its 100 00:04:29,879 --> 00:04:27,490 dynamic 101 00:04:32,900 --> 00:04:29,889 degree atmosphere the called the corona 102 00:04:35,129 --> 00:04:32,910 you can please show my next graphic 103 00:04:39,689 --> 00:04:35,139 Irish will join the Solar Dynamics 104 00:04:42,120 --> 00:04:39,699 Observatory or SEO and hinode together 105 00:04:45,540 --> 00:04:42,130 they'll explore how the solar atmosphere 106 00:04:47,670 --> 00:04:45,550 works and how it impacts the earth in OT 107 00:04:49,920 --> 00:04:47,680 and sdl looking at the surface of the 108 00:04:53,129 --> 00:04:49,930 sun and the upper Corona and iris 109 00:04:55,140 --> 00:04:53,139 looking at the region between if you 110 00:04:58,529 --> 00:04:55,150 look in this movie you see the full disk 111 00:05:00,809 --> 00:04:58,539 image as seen by sdl the corona inserted 112 00:05:03,570 --> 00:05:00,819 our images of the photosphere and the 113 00:05:05,370 --> 00:05:03,580 chromosphere from hinode iris will be 114 00:05:08,129 --> 00:05:05,380 the missing link between these two sets 115 00:05:09,960 --> 00:05:08,139 of observations now to tell you the 116 00:05:11,760 --> 00:05:09,970 details about this I'm pleased to 117 00:05:14,540 --> 00:05:11,770 introduce dr. Alan title the principal 118 00:05:19,050 --> 00:05:14,550 investigator of for iris thanks Jeff ah 119 00:05:23,820 --> 00:05:19,060 just by happenstance behind me as a 120 00:05:26,370 --> 00:05:23,830 background is a picture of IRS r and it 121 00:05:28,680 --> 00:05:26,380 happens to be full size so you can get 122 00:05:30,390 --> 00:05:28,690 an idea of the size of this mission it's 123 00:05:35,279 --> 00:05:30,400 not a great big huge thing if we could 124 00:05:37,529 --> 00:05:35,289 have the first slide iris is the 125 00:05:39,990 --> 00:05:37,539 interface region explore what is the 126 00:05:42,510 --> 00:05:40,000 interface the interface is the place 127 00:05:45,089 --> 00:05:42,520 where the visible surface the place 128 00:05:47,510 --> 00:05:45,099 where most of the light are virtually 129 00:05:50,870 --> 00:05:47,520 all the light that leaves the Sun ah 130 00:05:53,659 --> 00:05:50,880 leaves from it's about 6,000 degrees 131 00:05:57,749 --> 00:05:53,669 Kelvin are about a thousand degrees 132 00:06:00,450 --> 00:05:57,759 10,000 degrees Fahrenheit immediately 133 00:06:02,939 --> 00:06:00,460 above that in a ver the temperature 134 00:06:05,969 --> 00:06:02,949 rises to the million degrees of the 135 00:06:08,730 --> 00:06:05,979 corona how that happens is a mystery 136 00:06:11,790 --> 00:06:08,740 what are the processes that occur there 137 00:06:14,909 --> 00:06:11,800 what is iris going to do that's going to 138 00:06:19,050 --> 00:06:14,919 make a step forward first of all iris is 139 00:06:21,120 --> 00:06:19,060 about a factor of 10 higher resolution 140 00:06:23,700 --> 00:06:21,130 than any other instrument that has 141 00:06:25,950 --> 00:06:23,710 explored this region and even more 142 00:06:29,430 --> 00:06:25,960 importantly it's about a factor of 20 143 00:06:32,370 --> 00:06:29,440 faster so it can take images about once 144 00:06:35,100 --> 00:06:32,380 a second this is critical because the 145 00:06:38,490 --> 00:06:35,110 processes that occur in this part of the 146 00:06:40,230 --> 00:06:38,500 atmosphere happened very very fast and i 147 00:06:41,399 --> 00:06:40,240 hope i can show you that in the next few 148 00:06:44,339 --> 00:06:41,409 minutes but 149 00:06:48,029 --> 00:06:44,349 first let's take a trip from the surface 150 00:06:51,419 --> 00:06:48,039 of the Sun which we can see now that's 151 00:06:53,549 --> 00:06:51,429 the photosphere will blend into the 152 00:06:55,109 --> 00:06:53,559 magnetic field where black is magnetic 153 00:06:58,409 --> 00:06:55,119 field that's going out from the Sun 154 00:07:01,559 --> 00:06:58,419 white going back in and the white lines 155 00:07:04,469 --> 00:07:01,569 are a simulation of what we think the 156 00:07:07,769 --> 00:07:04,479 magnetic field is above that upper 157 00:07:09,629 --> 00:07:07,779 photosphere temperature goes up now 158 00:07:12,509 --> 00:07:09,639 we're into the transition region we're 159 00:07:15,449 --> 00:07:12,519 going from photospheric type of light 160 00:07:18,899 --> 00:07:15,459 the coronal type light where we can see 161 00:07:20,819 --> 00:07:18,909 sort of this iron filing picture which 162 00:07:24,059 --> 00:07:20,829 we can compare with what we see in the 163 00:07:25,859 --> 00:07:24,069 magnetic fields now I'll write to show 164 00:07:28,469 --> 00:07:25,869 you what we're going to try and target 165 00:07:31,559 --> 00:07:28,479 with iris so if we can have that movie 166 00:07:34,559 --> 00:07:31,569 on the top is the edge of the Sun and 167 00:07:36,989 --> 00:07:34,569 for context that blue ball is the earth 168 00:07:41,239 --> 00:07:36,999 so you can see these structures are as 169 00:07:44,369 --> 00:07:41,249 as long as the earth the panel below is 170 00:07:47,730 --> 00:07:44,379 enhanced and these very fine lines are 171 00:07:50,459 --> 00:07:47,740 the jets that deliver the energy into 172 00:07:52,859 --> 00:07:50,469 the upper atmosphere they look very 173 00:07:54,540 --> 00:07:52,869 small in this picture but there are 174 00:07:58,230 --> 00:07:54,550 about a hundred and twenty miles across 175 00:08:02,369 --> 00:07:58,240 and there about ten to fifty thousand 176 00:08:05,850 --> 00:08:02,379 miles long and they travel at about a 177 00:08:08,879 --> 00:08:05,860 hundred miles a second so in a couple of 178 00:08:11,129 --> 00:08:08,889 minutes one of those Jets can travel 179 00:08:13,350 --> 00:08:11,139 around the whole earth and they're about 180 00:08:16,799 --> 00:08:13,360 the size of Los Angeles so to get an 181 00:08:19,409 --> 00:08:16,809 idea it's sort of a feeling imagine an 182 00:08:22,169 --> 00:08:19,419 area the size of Los Angeles traveling 183 00:08:24,989 --> 00:08:22,179 around the world in two minutes so if we 184 00:08:27,659 --> 00:08:24,999 have the next slide this is a little bit 185 00:08:30,959 --> 00:08:27,669 more complicated region near a sunspot 186 00:08:32,850 --> 00:08:30,969 and besides these Jets we can see the 187 00:08:36,689 --> 00:08:32,860 large plumes associated with the 188 00:08:41,639 --> 00:08:36,699 sunspots and will show this twice 189 00:08:46,049 --> 00:08:41,649 because it's so pretty remember these 190 00:08:48,389 --> 00:08:46,059 things are going 100 miles a second now 191 00:08:50,910 --> 00:08:48,399 we can also see these Jets not only on 192 00:08:54,570 --> 00:08:50,920 the Sun but on the disk of the Sun so 193 00:08:57,540 --> 00:08:54,580 the next sequence will show 194 00:09:00,180 --> 00:08:57,550 a direct image and then an enhanced 195 00:09:04,350 --> 00:09:00,190 image and you can see in the green 196 00:09:07,560 --> 00:09:04,360 enhanced image these fine spider-like 197 00:09:10,350 --> 00:09:07,570 web structures all over the disk so 198 00:09:14,580 --> 00:09:10,360 these are the targets this is what we 199 00:09:17,520 --> 00:09:14,590 want to understand now the problem that 200 00:09:19,980 --> 00:09:17,530 we have is that we really can't see this 201 00:09:23,160 --> 00:09:19,990 region it's in light it's not visible 202 00:09:26,700 --> 00:09:23,170 and the physics is very complicated so 203 00:09:29,070 --> 00:09:26,710 there's been an international program to 204 00:09:32,760 --> 00:09:29,080 make synthetic images and so the next 205 00:09:40,110 --> 00:09:32,770 sequence will show synthetic images of 206 00:09:42,630 --> 00:09:40,120 the Sun and we'll also pan across the 207 00:09:45,180 --> 00:09:42,640 image and so you can see that these 208 00:09:47,010 --> 00:09:45,190 structures are highly three-dimensional 209 00:09:51,510 --> 00:09:47,020 they're not in a plane it's not a layer 210 00:09:54,450 --> 00:09:51,520 its columns of very rapidly evolving 211 00:09:56,670 --> 00:09:54,460 rapidly move rapidly expanding 212 00:10:05,160 --> 00:09:56,680 structures can we show that again 213 00:10:09,180 --> 00:10:05,170 because it's so much fun okay can we can 214 00:10:14,070 --> 00:10:09,190 we show it again please no you can't yes 215 00:10:19,650 --> 00:10:14,080 you can there he's doing it this this 216 00:10:22,410 --> 00:10:19,660 simulation took about three million CPU 217 00:10:26,370 --> 00:10:22,420 hours on one of the largest computing 218 00:10:28,140 --> 00:10:26,380 systems in the world now ah what I'd 219 00:10:31,020 --> 00:10:28,150 like to show you is not only do we have 220 00:10:34,020 --> 00:10:31,030 this simulation but we can use this 221 00:10:40,460 --> 00:10:34,030 simulation to show what these Jets are 222 00:10:49,050 --> 00:10:44,790 and now you can see models of the Jets 223 00:10:51,390 --> 00:10:49,060 and the colors indicate temperatures you 224 00:10:53,550 --> 00:10:51,400 can see the expanding plumes that we saw 225 00:10:59,700 --> 00:10:53,560 on the models and if we can have the 226 00:11:02,910 --> 00:10:59,710 next sequence this is another use of the 227 00:11:06,510 --> 00:11:02,920 simulation colors go from blue to red as 228 00:11:08,100 --> 00:11:06,520 the material heats so we have models of 229 00:11:10,530 --> 00:11:08,110 how the heating process 230 00:11:12,720 --> 00:11:10,540 works in some detail and these will be 231 00:11:15,000 --> 00:11:12,730 used to be compared with observations 232 00:11:17,069 --> 00:11:15,010 they're not observations and they may 233 00:11:20,790 --> 00:11:17,079 not be correct but they're a starting 234 00:11:24,269 --> 00:11:20,800 point so if we could go to this final 235 00:11:29,220 --> 00:11:24,279 couple of sequences this is what iris 236 00:11:32,069 --> 00:11:29,230 does ah could we have the sequence the 237 00:11:34,769 --> 00:11:32,079 yellow line corresponds to iris's 238 00:11:37,920 --> 00:11:34,779 spectrograph slit and on the right-hand 239 00:11:40,410 --> 00:11:37,930 side of that is what the spectrum will 240 00:11:43,259 --> 00:11:40,420 see from that slit and from those 241 00:11:46,319 --> 00:11:43,269 spectra we can construct images over a 242 00:11:48,810 --> 00:11:46,329 range of high temperatures and densities 243 00:11:51,120 --> 00:11:48,820 in the solar atmosphere so that's what 244 00:11:54,360 --> 00:11:51,130 iris data will look like to the 245 00:11:59,400 --> 00:11:54,370 scientists on the ground and then the 246 00:12:04,139 --> 00:11:59,410 final slide shows the comparison of iris 247 00:12:06,389 --> 00:12:04,149 with previous missions iris is in the 248 00:12:08,970 --> 00:12:06,399 middle and the two other missions are on 249 00:12:11,579 --> 00:12:08,980 the right and left and you can see how 250 00:12:15,210 --> 00:12:11,589 much narrower the spectrographs lid is 251 00:12:17,460 --> 00:12:15,220 and how much faster it moves and because 252 00:12:20,730 --> 00:12:17,470 of that we can actually reconstruct the 253 00:12:23,670 --> 00:12:20,740 motions in these Jets and now I'll turn 254 00:12:27,180 --> 00:12:23,680 this over to Gary Kushner who's had the 255 00:12:29,460 --> 00:12:27,190 enviable job of working with me and some 256 00:12:32,040 --> 00:12:29,470 of our scientists to actually build a 257 00:12:35,430 --> 00:12:32,050 thing that takes this kind of data Thank 258 00:12:37,980 --> 00:12:35,440 You Alan iris is a small lightweight low 259 00:12:40,710 --> 00:12:37,990 power satellite designed to perform 260 00:12:43,019 --> 00:12:40,720 complex solar observations iris is a 261 00:12:45,870 --> 00:12:43,029 NASA small Explorer mission we will fly 262 00:12:47,400 --> 00:12:45,880 in a Sun pointing polar orbit about six 263 00:12:50,040 --> 00:12:47,410 hundred sixty kilometers in low-earth 264 00:12:52,410 --> 00:12:50,050 orbit iris is the culmination of three 265 00:12:54,689 --> 00:12:52,420 years and about nine months of effort by 266 00:12:56,009 --> 00:12:54,699 a team including people from Lockheed 267 00:12:58,370 --> 00:12:56,019 Martin Smithsonian Astrophysical 268 00:13:01,319 --> 00:12:58,380 Observatory Montana State University 269 00:13:04,710 --> 00:13:01,329 University of Oslo and with NASA Ames 270 00:13:07,110 --> 00:13:04,720 Research Center on the first graphic 271 00:13:09,810 --> 00:13:07,120 you'll see is a graphic of the 272 00:13:12,480 --> 00:13:09,820 observatory the left the orange area is 273 00:13:14,310 --> 00:13:12,490 the spacecraft bus the green and light 274 00:13:16,260 --> 00:13:14,320 blue area is the instrument we'll talk a 275 00:13:19,829 --> 00:13:16,270 little bit about that more in a moment 276 00:13:21,540 --> 00:13:19,839 on it is about seven feet in length and 277 00:13:24,240 --> 00:13:21,550 four feet in diameter 278 00:13:27,389 --> 00:13:24,250 spacecraft and 12 feet in width with the 279 00:13:29,910 --> 00:13:27,399 solar arrays deployed on the next 280 00:13:31,530 --> 00:13:29,920 graphic you can see this is an image of 281 00:13:33,180 --> 00:13:31,540 the actual observatory with the solar 282 00:13:35,400 --> 00:13:33,190 arrays deployed this is in the clean 283 00:13:37,650 --> 00:13:35,410 room at Lockheed Martin and in the next 284 00:13:40,380 --> 00:13:37,660 graphic you can see it with the solar 285 00:13:41,850 --> 00:13:40,390 rays stowed this is in preparation for 286 00:13:46,530 --> 00:13:41,860 one of the environmental tests of 287 00:13:50,340 --> 00:13:46,540 vibration testing in the next graphic on 288 00:13:52,500 --> 00:13:50,350 this is the instrument by itself to the 289 00:13:55,139 --> 00:13:52,510 left of the white collar is the 290 00:13:57,690 --> 00:13:55,149 telescope assembly to the right of the 291 00:13:59,699 --> 00:13:57,700 collar is the spectrograph assembly and 292 00:14:02,130 --> 00:13:59,709 the white collar itself is a thermal 293 00:14:05,490 --> 00:14:02,140 radiator for the primary mirror which 294 00:14:08,880 --> 00:14:05,500 sees the Sun this is the optical payload 295 00:14:10,829 --> 00:14:08,890 and in the next series of images they'll 296 00:14:12,750 --> 00:14:10,839 cycle through this is the graphic of the 297 00:14:15,030 --> 00:14:12,760 payload with kind of the sides slowly 298 00:14:17,460 --> 00:14:15,040 cut away and you'll see that if you're 299 00:14:19,380 --> 00:14:17,470 the Sun is to the right you'll see there 300 00:14:22,230 --> 00:14:19,390 that the red Ray's represent the 301 00:14:25,470 --> 00:14:22,240 telescope assembly and that is the light 302 00:14:27,960 --> 00:14:25,480 being focused and projected onto the 303 00:14:29,340 --> 00:14:27,970 spectrograph which is to the left of 304 00:14:32,280 --> 00:14:29,350 what you see as the green collar and 305 00:14:34,829 --> 00:14:32,290 you'll see the blue and green rays 306 00:14:37,139 --> 00:14:34,839 that's the spectrograph and that breaks 307 00:14:39,240 --> 00:14:37,149 the light into its four channels the 308 00:14:42,990 --> 00:14:39,250 faro violet and near ultraviolet and 309 00:14:45,180 --> 00:14:43,000 then that is put on to the sea CDs and 310 00:14:51,150 --> 00:14:45,190 the cameras and then projected down onto 311 00:14:53,069 --> 00:14:51,160 the earth on the next graphic there we 312 00:14:54,930 --> 00:14:53,079 go this is so that was the instrument 313 00:14:57,420 --> 00:14:54,940 and now supporting the instrument is the 314 00:14:59,160 --> 00:14:57,430 spacecraft bus these series of images 315 00:15:01,800 --> 00:14:59,170 shows how you take a large block of 316 00:15:04,319 --> 00:15:01,810 aluminum and quickly in a few steps 317 00:15:06,449 --> 00:15:04,329 convert it into a monolithic spacecraft 318 00:15:07,350 --> 00:15:06,459 bus it actually takes many steps you can 319 00:15:09,600 --> 00:15:07,360 see that they went through rough 320 00:15:11,340 --> 00:15:09,610 machining fine machining and they're 321 00:15:13,170 --> 00:15:11,350 testing the they're assembling the 322 00:15:15,090 --> 00:15:13,180 panel's there and then you end up with a 323 00:15:18,019 --> 00:15:15,100 full spacecraft bus with all of its 324 00:15:21,600 --> 00:15:18,029 components inside the spacecraft bus 325 00:15:25,380 --> 00:15:21,610 includes a pointing system a power 326 00:15:29,100 --> 00:15:25,390 system and all the components of a large 327 00:15:31,230 --> 00:15:29,110 spacecraft bus the next image is the 328 00:15:33,569 --> 00:15:31,240 observatory fully assembled this is 329 00:15:35,010 --> 00:15:33,579 coming out of thermal vacuum testing you 330 00:15:36,570 --> 00:15:35,020 can see the spacecraft is 331 00:15:37,880 --> 00:15:36,580 at the bottom of your screen and the 332 00:15:42,480 --> 00:15:37,890 instrument is at the top of your screen 333 00:15:45,530 --> 00:15:42,490 the next movie we show it will be of the 334 00:15:48,660 --> 00:15:45,540 observatory coming out of vacuum testing 335 00:15:51,120 --> 00:15:48,670 there you go and this is it being 336 00:15:54,390 --> 00:15:51,130 prepared after vacuum testing be 337 00:15:56,550 --> 00:15:54,400 prepared for movement back to its clean 338 00:15:58,440 --> 00:15:56,560 room while you saw before with its 339 00:16:00,720 --> 00:15:58,450 already deployed here it is in the clean 340 00:16:04,290 --> 00:16:00,730 room preparing for a final solar a 341 00:16:06,600 --> 00:16:04,300 deployment that's the solar array facing 342 00:16:08,400 --> 00:16:06,610 you and it will deploy by a flight 343 00:16:10,530 --> 00:16:08,410 command here through the computer 344 00:16:14,640 --> 00:16:10,540 through the spacecraft you'll see that 345 00:16:17,370 --> 00:16:14,650 the arrays deploying right there in this 346 00:16:18,960 --> 00:16:17,380 you can also see that the shiny material 347 00:16:21,150 --> 00:16:18,970 that is the thermal protection system 348 00:16:23,010 --> 00:16:21,160 those are what we call blankets those 349 00:16:24,840 --> 00:16:23,020 protect it while it's on orbit this view 350 00:16:29,190 --> 00:16:24,850 is how it will look on orbit with the 351 00:16:30,810 --> 00:16:29,200 front door opening and the Sun will be 352 00:16:32,190 --> 00:16:30,820 would have been to your right and this 353 00:16:35,850 --> 00:16:32,200 is pretty much how it will look on orbit 354 00:16:38,340 --> 00:16:35,860 and then this is a nice kind of scan 355 00:16:41,130 --> 00:16:38,350 view of it fully deployed this is about 356 00:16:46,530 --> 00:16:41,140 the last testing we do before we ship it 357 00:16:48,540 --> 00:16:46,540 down to Vandenberg on the next series of 358 00:16:51,060 --> 00:16:48,550 videos this we ship to Vandenberg on 359 00:16:53,730 --> 00:16:51,070 April sixteenth this is the observatory 360 00:16:56,700 --> 00:16:53,740 arriving and being off loaded the truck 361 00:16:59,820 --> 00:16:56,710 and being transferred to its handling 362 00:17:01,860 --> 00:16:59,830 fixture it will then be transferred from 363 00:17:03,900 --> 00:17:01,870 its handling fixture into the cleanroom 364 00:17:05,610 --> 00:17:03,910 there if you look quickly you can see to 365 00:17:07,920 --> 00:17:05,620 the left that is the third stage of the 366 00:17:09,990 --> 00:17:07,930 Pegasus rocket and in the cleanroom we 367 00:17:13,770 --> 00:17:10,000 do our final preparations and prepare 368 00:17:16,290 --> 00:17:13,780 for mating to the rocket and we do 369 00:17:18,270 --> 00:17:16,300 several steps to prepare the separation 370 00:17:20,190 --> 00:17:18,280 system and installation on to the rocket 371 00:17:23,670 --> 00:17:20,200 here you can see the crew in various 372 00:17:25,470 --> 00:17:23,680 stages of assembly that is the 373 00:17:27,960 --> 00:17:25,480 separation system means tumble has 374 00:17:30,270 --> 00:17:27,970 installed there and this is the orbital 375 00:17:33,120 --> 00:17:30,280 Pegasus rocket that will take us into 376 00:17:36,090 --> 00:17:33,130 orbit and that's the another view of it 377 00:17:37,590 --> 00:17:36,100 and after we are made it to the rocket 378 00:17:39,360 --> 00:17:37,600 they put on what are called fairings 379 00:17:41,340 --> 00:17:39,370 these are a view of the fairings that 380 00:17:43,770 --> 00:17:41,350 are being prepared for installation now 381 00:17:47,100 --> 00:17:43,780 and they will be installed on the rocket 382 00:17:48,940 --> 00:17:47,110 at the beginning of next week we will be 383 00:17:51,040 --> 00:17:48,950 launching on jun 26 384 00:17:53,680 --> 00:17:51,050 this next graphic will show you how we 385 00:17:55,000 --> 00:17:53,690 get into orbit this is the Pegasus 386 00:17:57,100 --> 00:17:55,010 rocket is actually launched from the 387 00:18:00,630 --> 00:17:57,110 bottom of an airplane is dropped at 388 00:18:03,520 --> 00:18:00,640 39,000 feet the first stage is ignited 389 00:18:06,550 --> 00:18:03,530 and it actually and then the this is now 390 00:18:09,760 --> 00:18:06,560 showing the second stage being propelled 391 00:18:11,410 --> 00:18:09,770 into orbit the second stage about 120 392 00:18:14,130 --> 00:18:11,420 one second hundred thirty-one seconds 393 00:18:16,750 --> 00:18:14,140 into orbit the fairing will separate and 394 00:18:18,400 --> 00:18:16,760 because we're above the atmosphere the 395 00:18:21,070 --> 00:18:18,410 second stage will burn for a few more 396 00:18:25,960 --> 00:18:21,080 seconds and then it will transition to 397 00:18:28,120 --> 00:18:25,970 the third stage the third stage will 398 00:18:32,470 --> 00:18:28,130 then put us into our final orbit of 600 399 00:18:34,900 --> 00:18:32,480 620 by six seventy kilometers when this 400 00:18:37,390 --> 00:18:34,910 third stage finishes it will separate 401 00:18:40,270 --> 00:18:37,400 from the observatory and then actually 402 00:18:42,490 --> 00:18:40,280 walk does maneuvers to get away we will 403 00:18:45,070 --> 00:18:42,500 deploy the solar rays acquire Sun and go 404 00:18:47,200 --> 00:18:45,080 power positive and then 21 days into the 405 00:18:51,100 --> 00:18:47,210 mission we will open the door and start 406 00:18:54,040 --> 00:18:51,110 doing calibrations with a light but to 407 00:18:56,700 --> 00:18:54,050 further discuss how we do it how we get 408 00:18:59,500 --> 00:18:56,710 the data down from orbit and how we 409 00:19:01,930 --> 00:18:59,510 operate the observatory I will hand off 410 00:19:04,000 --> 00:19:01,940 to John Murray thank you Gary I'll 411 00:19:06,310 --> 00:19:04,010 present a look at operations and data 412 00:19:08,560 --> 00:19:06,320 flow for the iris mission but first 413 00:19:10,360 --> 00:19:08,570 though iris is a perfect example of how 414 00:19:12,730 --> 00:19:10,370 collaborative efforts between the 415 00:19:15,040 --> 00:19:12,740 government academia and the private 416 00:19:17,260 --> 00:19:15,050 sector can use the expertise of each 417 00:19:20,740 --> 00:19:17,270 institution to result in cost savings 418 00:19:23,410 --> 00:19:20,750 for the overall mission I enjoy serving 419 00:19:25,240 --> 00:19:23,420 in my role as the system project manager 420 00:19:27,220 --> 00:19:25,250 working directly with Alan and Gary on 421 00:19:28,930 --> 00:19:27,230 this mission and others Lockheed Martin 422 00:19:32,290 --> 00:19:28,940 to help facilitate this productive 423 00:19:34,420 --> 00:19:32,300 relationship alright first clip this 424 00:19:36,580 --> 00:19:34,430 clip shows a few the Irish team members 425 00:19:39,550 --> 00:19:36,590 in the Mission Operations Center at NASA 426 00:19:43,030 --> 00:19:39,560 Ames Ames Mission Operations Center 427 00:19:45,270 --> 00:19:43,040 serves as an example of a small low-cost 428 00:19:47,470 --> 00:19:45,280 flight operations facility for NASA 429 00:19:49,900 --> 00:19:47,480 mission operations center is staffed 430 00:19:52,180 --> 00:19:49,910 twenty-four seven for the first seven 431 00:19:54,340 --> 00:19:52,190 days of light then when all is nominal 432 00:19:57,700 --> 00:19:54,350 they eventually transition down to one 433 00:20:01,270 --> 00:19:57,710 shift per working day each one command 434 00:20:02,680 --> 00:20:01,280 load it occurs / once per week day with 435 00:20:04,900 --> 00:20:02,690 science and spacecraft 436 00:20:08,920 --> 00:20:04,910 health data received daily in a 437 00:20:11,920 --> 00:20:08,930 lights-out mode next clip please iris is 438 00:20:12,960 --> 00:20:11,930 launched into a 620 kilometer by six 439 00:20:15,940 --> 00:20:12,970 hundred and seventy kilometers 440 00:20:17,290 --> 00:20:15,950 sun-synchronous polar orbit at an 441 00:20:19,210 --> 00:20:17,300 inclination of approximately 442 00:20:22,840 --> 00:20:19,220 ninety-eight degrees so what's that mean 443 00:20:25,810 --> 00:20:22,850 iris flies on the dawn dusk line and 444 00:20:29,020 --> 00:20:25,820 always looks towards the Sun each orbit 445 00:20:32,140 --> 00:20:29,030 takes iris on the order of 97 minutes to 446 00:20:35,050 --> 00:20:32,150 complete which allows 14 to 15 passes 447 00:20:38,290 --> 00:20:35,060 per day this orbit was selected to 448 00:20:45,370 --> 00:20:38,300 maximize downlink data volume as well as 449 00:20:47,170 --> 00:20:45,380 sun exposure time explains communicating 450 00:20:50,170 --> 00:20:47,180 with the tracking and data relay 451 00:20:52,090 --> 00:20:50,180 satellite system within 15 minutes the 452 00:20:54,160 --> 00:20:52,100 solar arrays should be deployed and 453 00:20:56,260 --> 00:20:54,170 we're over McMurdo ground station 454 00:20:58,060 --> 00:20:56,270 Antarctica within 60 minutes we 455 00:21:00,310 --> 00:20:58,070 Passover's fall bar ground station 456 00:21:03,880 --> 00:21:00,320 Norway 10 minutes later were over the 457 00:21:05,980 --> 00:21:03,890 Alaska satellite facility each orbit or 458 00:21:10,890 --> 00:21:05,990 ground track that you see here takes on 459 00:21:13,690 --> 00:21:10,900 the order of 97 minutes to complete so 460 00:21:16,270 --> 00:21:13,700 and Wallops ground station actually 461 00:21:21,160 --> 00:21:16,280 comes into view I own the fifth orbit 462 00:21:23,230 --> 00:21:21,170 next clip please the primary facilities 463 00:21:25,240 --> 00:21:23,240 used to support the iris mission are the 464 00:21:28,090 --> 00:21:25,250 instrument operation center at Lockheed 465 00:21:29,440 --> 00:21:28,100 Martin solar in astrophysics lab in Palo 466 00:21:32,440 --> 00:21:29,450 Alto we have the Mission Operations 467 00:21:34,420 --> 00:21:32,450 Center at NASA Ames Research Center we 468 00:21:36,820 --> 00:21:34,430 also have the near Earth network at 469 00:21:39,220 --> 00:21:36,830 Goddard Space Flight Center we have the 470 00:21:41,950 --> 00:21:39,230 small small bar ground facility as fall 471 00:21:43,480 --> 00:21:41,960 bard Norway we collaborate with the 472 00:21:46,390 --> 00:21:43,490 norwegian space that are on this mission 473 00:21:49,390 --> 00:21:46,400 we have the alaska science facility in 474 00:21:51,790 --> 00:21:49,400 fairbanks alaska McMurdo ground station 475 00:21:53,620 --> 00:21:51,800 in Antarctica we have the wall up the 476 00:21:56,080 --> 00:21:53,630 ground station wall up to Island 477 00:21:58,330 --> 00:21:56,090 Virginia data eventually makes its way 478 00:22:00,580 --> 00:21:58,340 to the Mission Operations Center we send 479 00:22:02,830 --> 00:22:00,590 that off to Stanford to the science data 480 00:22:07,360 --> 00:22:02,840 processing facility where it is 481 00:22:09,340 --> 00:22:07,370 available on the web next slide an Irish 482 00:22:11,110 --> 00:22:09,350 stay in the life for the team on the 483 00:22:14,110 --> 00:22:11,120 ground actually begins with the science 484 00:22:16,180 --> 00:22:14,120 team creating a daily plan they'll take 485 00:22:18,279 --> 00:22:16,190 a look at previous images they'll 486 00:22:19,810 --> 00:22:18,289 take a pointing requests they'll take 487 00:22:22,360 --> 00:22:19,820 science requests and they'll also take 488 00:22:24,430 --> 00:22:22,370 into account the spacecraft health they 489 00:22:26,499 --> 00:22:24,440 pass it along to Mission Operations team 490 00:22:29,350 --> 00:22:26,509 where they begin to assemble the command 491 00:22:32,259 --> 00:22:29,360 load they'll take that spacecraft input 492 00:22:33,940 --> 00:22:32,269 they'll Jill take those sequences those 493 00:22:35,560 --> 00:22:33,950 pointing sequences there's science 494 00:22:37,960 --> 00:22:35,570 sequences and generate the command 495 00:22:39,759 --> 00:22:37,970 secrets at that point they then package 496 00:22:41,529 --> 00:22:39,769 that command they'll have worked with 497 00:22:43,869 --> 00:22:41,539 the ground stations beforehand to 498 00:22:46,240 --> 00:22:43,879 schedule time they'll build the scripts 499 00:22:49,330 --> 00:22:46,250 to automate that process o verify the 500 00:22:51,249 --> 00:22:49,340 command sequence approximately 6 p.m. 501 00:22:53,919 --> 00:22:51,259 every day flight controllers then 502 00:22:56,680 --> 00:22:53,929 execute the commands they'll establish 503 00:22:59,590 --> 00:22:56,690 link with the ground station upload the 504 00:23:02,649 --> 00:22:59,600 command and then they release the ground 505 00:23:04,869 --> 00:23:02,659 station link after which telemetry is 506 00:23:07,029 --> 00:23:04,879 received they assess the spacecraft 507 00:23:09,700 --> 00:23:07,039 health they'll send out alerts and 508 00:23:12,039 --> 00:23:09,710 notifications data is then since 509 00:23:14,850 --> 00:23:12,049 Stanford where it's processed stored 510 00:23:18,519 --> 00:23:14,860 science data is and posted to the web 511 00:23:21,009 --> 00:23:18,529 within six hours receipt although quick 512 00:23:24,610 --> 00:23:21,019 looks of the images of the data will be 513 00:23:26,919 --> 00:23:24,620 available within 10 minutes this solar 514 00:23:29,649 --> 00:23:26,929 data is then used in multiple ways to 515 00:23:33,330 --> 00:23:29,659 benefit society here on earth as well as 516 00:23:36,539 --> 00:23:33,340 for space exploration next slide please 517 00:23:39,220 --> 00:23:36,549 so the Irish mission starts with launch 518 00:23:42,369 --> 00:23:39,230 separation occurs 13 minutes after 519 00:23:44,799 --> 00:23:42,379 launch the spacecraft II tumbles opens a 520 00:23:46,539 --> 00:23:44,809 solar arrays begins communicating so for 521 00:23:48,549 --> 00:23:46,549 the next 30 days we check out the 522 00:23:52,119 --> 00:23:48,559 instrument we check out the spacecraft 523 00:23:54,220 --> 00:23:52,129 on day 21 we open the telescope door the 524 00:23:57,940 --> 00:23:54,230 science campaign officially starts on 525 00:24:01,539 --> 00:23:57,950 day 60 as we begin our exploration of 526 00:24:04,629 --> 00:24:01,549 the Sun for the next two years we're in 527 00:24:07,720 --> 00:24:04,639 nominal operations so given there's no 528 00:24:09,669 --> 00:24:07,730 fuel on board if after two years the 529 00:24:13,090 --> 00:24:09,679 observatory is healthy and productive 530 00:24:16,419 --> 00:24:13,100 NASA then has the option to extend 531 00:24:18,700 --> 00:24:16,429 science operations theoretically iris 532 00:24:22,450 --> 00:24:18,710 could be productive for a few decades if 533 00:24:24,340 --> 00:24:22,460 the observatory is healthy and that is a 534 00:24:26,399 --> 00:24:24,350 look at the iris operations for this 535 00:24:28,570 --> 00:24:26,409 exciting mission go back to you Steve 536 00:24:29,830 --> 00:24:28,580 okay thank you John and all our 537 00:24:32,620 --> 00:24:29,840 panelists now we can 538 00:24:34,419 --> 00:24:32,630 go to questions if you're on the phone 539 00:24:37,990 --> 00:24:34,429 bridge or reporters and you'd like to 540 00:24:40,360 --> 00:24:38,000 ask a question please hit star one if 541 00:24:42,210 --> 00:24:40,370 you're watching online and would like to 542 00:24:46,630 --> 00:24:42,220 ask our panelists a question on Twitter 543 00:24:49,000 --> 00:24:46,640 use the hashtag ask NASA that we also 544 00:24:52,299 --> 00:24:49,010 have graphics online everything you've 545 00:24:56,049 --> 00:24:52,309 seen here is available online you just 546 00:25:01,570 --> 00:24:56,059 need to go to a website it's go nasa.gov 547 00:25:05,440 --> 00:25:01,580 slash irish iris graphics there's the 548 00:25:08,260 --> 00:25:05,450 URL right there okay we'll start our 549 00:25:10,269 --> 00:25:08,270 questions from social media I think we 550 00:25:11,919 --> 00:25:10,279 have some from Twitter thank you Steve 551 00:25:14,710 --> 00:25:11,929 the first question that we have for the 552 00:25:20,590 --> 00:25:14,720 panel is what do you hope to discover or 553 00:25:23,200 --> 00:25:20,600 find during the iris mission what we 554 00:25:26,649 --> 00:25:23,210 want to discover is what the basic 555 00:25:30,940 --> 00:25:26,659 physical processes are the transfer 556 00:25:33,730 --> 00:25:30,950 energy and material from the surface of 557 00:25:36,990 --> 00:25:33,740 the sun out to the outer atmosphere to 558 00:25:39,880 --> 00:25:37,000 the corona and remember the corona 559 00:25:46,180 --> 00:25:39,890 extends throughout the heliosphere we 560 00:25:47,560 --> 00:25:46,190 live in the sun's outer atmosphere okay 561 00:25:50,500 --> 00:25:47,570 another question from Twitter please 562 00:25:58,230 --> 00:25:50,510 thank you how many pixels will the 563 00:26:02,710 --> 00:25:58,240 images that iris takes have um we have 564 00:26:07,180 --> 00:26:02,720 three ccd detectors that are roughly 565 00:26:12,730 --> 00:26:07,190 2,000 by 2,000 oh but we won't use all 566 00:26:14,919 --> 00:26:12,740 of them all the time okay and we have 567 00:26:17,710 --> 00:26:14,929 one more question from Twitter before we 568 00:26:19,600 --> 00:26:17,720 go to the phone lines okay thank you how 569 00:26:23,019 --> 00:26:19,610 far away from the Sun will Irish be 570 00:26:27,850 --> 00:26:23,029 while it's taking its measurements iris 571 00:26:32,649 --> 00:26:27,860 flies around the earth so it only gets 572 00:26:35,649 --> 00:26:32,659 about 600 kilometers closer to the Sun 573 00:26:39,250 --> 00:26:35,659 then here we are on earth and that's 574 00:26:42,040 --> 00:26:39,260 about 92 million miles away so it's 575 00:26:45,580 --> 00:26:42,050 really not very much closer to this side 576 00:26:47,470 --> 00:26:45,590 just stares a long time okay and now we 577 00:26:52,650 --> 00:26:47,480 have a question from the phone bridge 578 00:26:58,600 --> 00:26:55,270 hi thanks for taking my question am I 579 00:27:01,210 --> 00:26:58,610 thinking for Alan um what happens in the 580 00:27:03,700 --> 00:27:01,220 interface region during solar storms and 581 00:27:10,090 --> 00:27:03,710 are you expecting our see changes during 582 00:27:15,970 --> 00:27:10,100 solar maximum absolutely ah the second 583 00:27:19,300 --> 00:27:15,980 ah view of the Sun the one that showed 584 00:27:23,290 --> 00:27:19,310 the region around the Sun SPOT showed 585 00:27:28,030 --> 00:27:23,300 the kind of activity that happens in a 586 00:27:32,920 --> 00:27:28,040 rather quiescent active region in so 587 00:27:35,380 --> 00:27:32,930 regardless of exactly where we are ah in 588 00:27:37,690 --> 00:27:35,390 the solar cycle and right now we're 589 00:27:41,190 --> 00:27:37,700 pretty much a solar maximum we're going 590 00:27:44,860 --> 00:27:41,200 to see a lot of activity and we have 591 00:27:47,800 --> 00:27:44,870 pre-planned a large number of herbs or 592 00:27:52,180 --> 00:27:47,810 observing sequences that are targeted to 593 00:27:54,040 --> 00:27:52,190 seeing things like solar flares our next 594 00:27:57,460 --> 00:27:54,050 question is also from the phone line 595 00:28:02,290 --> 00:27:57,470 it's alex we see from nature go ahead 596 00:28:04,750 --> 00:28:02,300 Alex thank you my question is also for 597 00:28:07,660 --> 00:28:04,760 dr. title I wanted to ask about this 598 00:28:10,000 --> 00:28:07,670 Swede balloon experiment that will be 599 00:28:13,150 --> 00:28:10,010 flown over Sweden also this summer 600 00:28:15,610 --> 00:28:13,160 called sunrise how will that compliment 601 00:28:22,390 --> 00:28:15,620 or not complement what you're doing with 602 00:28:26,170 --> 00:28:22,400 iris well unfortunately the sunrise 603 00:28:30,240 --> 00:28:26,180 flight is supposed to be in the next few 604 00:28:33,940 --> 00:28:30,250 days now that's nice for sunrise I wish 605 00:28:36,520 --> 00:28:33,950 that it flown at the same time as IRS 606 00:28:39,940 --> 00:28:36,530 but I guess that's something that just 607 00:28:45,430 --> 00:28:39,950 didn't happen ah but sunrise is a very 608 00:28:47,710 --> 00:28:45,440 important very highly capable experiment 609 00:28:49,660 --> 00:28:47,720 and it will tell us a lot about the 610 00:28:52,240 --> 00:28:49,670 smallest magnetic field structures on 611 00:28:55,240 --> 00:28:52,250 the Sun and the more that we know about 612 00:28:56,040 --> 00:28:55,250 the driving magnetic fields the more 613 00:28:57,870 --> 00:28:56,050 easily will 614 00:29:01,920 --> 00:28:57,880 be able to interpret the results that we 615 00:29:03,570 --> 00:29:01,930 get from iris we have another question 616 00:29:10,650 --> 00:29:03,580 on the phone lines Rebecca Boyle 617 00:29:12,360 --> 00:29:10,660 freelancer hi everybody um no exercise 618 00:29:14,640 --> 00:29:12,370 was just asked but I have a quick 619 00:29:16,560 --> 00:29:14,650 follow-up about it I guess how could 620 00:29:19,100 --> 00:29:16,570 balloon machines like sunrise or 621 00:29:21,240 --> 00:29:19,110 stunning Rockets like the hi-c mission 622 00:29:24,120 --> 00:29:21,250 complement what you're doing with iris 623 00:29:25,470 --> 00:29:24,130 could you sort of have a fast reaction 624 00:29:28,320 --> 00:29:25,480 possibly do something that you've seen 625 00:29:31,880 --> 00:29:28,330 with iris and send us a quick balloon or 626 00:29:34,830 --> 00:29:31,890 signing rocket to take a further look I 627 00:29:40,860 --> 00:29:34,840 guess that's really a question for Jeff 628 00:29:44,640 --> 00:29:40,870 numark ah that I would hope that of the 629 00:29:49,140 --> 00:29:44,650 combination of iris and the Solar 630 00:29:53,100 --> 00:29:49,150 Dynamics Observatory and observations on 631 00:29:56,160 --> 00:29:53,110 stereo would encourage NASA to take 632 00:29:58,770 --> 00:29:56,170 advantage of any relatively low-cost 633 00:30:02,760 --> 00:29:58,780 mission that they could under fly with 634 00:30:05,610 --> 00:30:02,770 iris and certainly balloon flights can 635 00:30:08,610 --> 00:30:05,620 be rescheduled they're not free and 636 00:30:11,100 --> 00:30:08,620 neither or rockets though planning has 637 00:30:14,880 --> 00:30:11,110 to occur and budgets have to be found 638 00:30:18,420 --> 00:30:14,890 but hopefully they will be I would just 639 00:30:21,210 --> 00:30:18,430 like to add that we certainly try and 640 00:30:25,560 --> 00:30:21,220 coordinate whenever we can our various 641 00:30:30,120 --> 00:30:25,570 missions it is difficult some to to 642 00:30:32,610 --> 00:30:30,130 always have a very quick reaction maybe 643 00:30:35,910 --> 00:30:32,620 the processes that you saw in the 644 00:30:38,880 --> 00:30:35,920 wonderful movies and simulations that 645 00:30:40,020 --> 00:30:38,890 Alan showed you were within seconds and 646 00:30:42,900 --> 00:30:40,030 minutes these are very very quick 647 00:30:45,450 --> 00:30:42,910 processes so the two to have that kind 648 00:30:48,000 --> 00:30:45,460 of turnaround on a balloon or sounding 649 00:30:50,070 --> 00:30:48,010 rocket is not always feasible but as a 650 00:30:51,870 --> 00:30:50,080 general rule we do like to try and 651 00:30:54,120 --> 00:30:51,880 coordinate with as many of our assets as 652 00:30:56,100 --> 00:30:54,130 possible and that's one of the reasons 653 00:30:58,560 --> 00:30:56,110 that I tried to show our system 654 00:31:01,260 --> 00:30:58,570 observatory that we have is because it 655 00:31:03,480 --> 00:31:01,270 is through a distributed network a large 656 00:31:06,960 --> 00:31:03,490 number of observations that we will make 657 00:31:09,060 --> 00:31:06,970 real advancement all right we have 658 00:31:10,019 --> 00:31:09,070 another caller on the line but first to 659 00:31:12,389 --> 00:31:10,029 remind the 660 00:31:14,580 --> 00:31:12,399 analyst on the phone lines to hit star 661 00:31:17,459 --> 00:31:14,590 one if you'd like to ask a question our 662 00:31:21,889 --> 00:31:17,469 next question comes from Irene Klotz at 663 00:31:25,019 --> 00:31:21,899 Reuters go ahead Irene thanks Steve 664 00:31:28,349 --> 00:31:25,029 sometimes I miss this which is a design 665 00:31:31,259 --> 00:31:28,359 lifetime of the satellite and someone 666 00:31:34,019 --> 00:31:31,269 else's please give us a raw mission 667 00:31:36,539 --> 00:31:34,029 costs either with without the launch 668 00:31:41,190 --> 00:31:36,549 however you break up separate or 669 00:31:44,789 --> 00:31:41,200 together thanks I'll sort of the cost 670 00:31:47,279 --> 00:31:44,799 the cost is just over 181 million 671 00:31:51,229 --> 00:31:47,289 dollars in really year dollars and that 672 00:31:54,810 --> 00:31:51,239 includes the the development of the 673 00:31:56,609 --> 00:31:54,820 spacecraft the satellite of and the 674 00:31:59,759 --> 00:31:56,619 instrument and and also a launch vehicle 675 00:32:03,119 --> 00:31:59,769 and management of the whole mission is 676 00:32:06,119 --> 00:32:03,129 included and it has a tui just over two 677 00:32:08,639 --> 00:32:06,129 year design life time though as John 678 00:32:11,399 --> 00:32:08,649 mentioned there are no consumables on 679 00:32:13,109 --> 00:32:11,409 board and and and there's a strong 680 00:32:16,950 --> 00:32:13,119 possibility that iris will last much 681 00:32:19,379 --> 00:32:16,960 longer than that iris which is was 682 00:32:23,959 --> 00:32:19,389 designed to the same sort of design 683 00:32:28,619 --> 00:32:23,969 rules operated for 10 years tres tres 684 00:32:33,570 --> 00:32:28,629 I'm sorry I keep doing that but a trace 685 00:32:36,959 --> 00:32:33,580 up iris trace operated for a decade and 686 00:32:39,149 --> 00:32:36,969 it was still working just fine when we 687 00:32:41,669 --> 00:32:39,159 turned it off and we turned it off 688 00:32:46,079 --> 00:32:41,679 because it was replaced by the Solar 689 00:32:49,139 --> 00:32:46,089 Dynamics Observatory our next questions 690 00:32:51,779 --> 00:32:49,149 come from Twitter again how much of the 691 00:32:56,459 --> 00:32:51,789 data obtained by iris will be in the 692 00:32:59,669 --> 00:32:56,469 public domain all of it thank you all of 693 00:33:04,979 --> 00:32:59,679 it at the same time as the science teams 694 00:33:07,379 --> 00:33:04,989 get it and that's true for all sto data 695 00:33:10,169 --> 00:33:07,389 and I think virtually all of 696 00:33:13,649 --> 00:33:10,179 heliophysics data is made available to 697 00:33:15,269 --> 00:33:13,659 the general public at the same time is 698 00:33:18,529 --> 00:33:15,279 made available to this idea the 699 00:33:21,450 --> 00:33:18,539 community next question from online 700 00:33:23,880 --> 00:33:21,460 someone asks are there any advantages 701 00:33:27,620 --> 00:33:23,890 for future missions to put an 702 00:33:32,940 --> 00:33:27,630 an iris type vehicle closer to the Sun 703 00:33:36,510 --> 00:33:32,950 um I'll take that we do actually have a 704 00:33:39,090 --> 00:33:36,520 couple of missions coming up in another 705 00:33:40,800 --> 00:33:39,100 few years one a collaboration with the 706 00:33:43,770 --> 00:33:40,810 european space agency called solar 707 00:33:46,860 --> 00:33:43,780 orbiter and and one nasa mission called 708 00:33:48,720 --> 00:33:46,870 solar probe plus both of these missions 709 00:33:52,110 --> 00:33:48,730 in fact are going closer to the Sun 710 00:33:56,670 --> 00:33:52,120 solar probe plus will actually fly into 711 00:33:59,100 --> 00:33:56,680 the near corona of the Sun and these 712 00:34:01,560 --> 00:33:59,110 missions will complement the Irish type 713 00:34:03,780 --> 00:34:01,570 where Irish is looking at the base of 714 00:34:05,580 --> 00:34:03,790 the solar atmosphere the way the solar 715 00:34:07,380 --> 00:34:05,590 wind originates and these future 716 00:34:10,800 --> 00:34:07,390 missions will actually look a little bit 717 00:34:14,510 --> 00:34:10,810 further up as the solar wind accelerates 718 00:34:18,240 --> 00:34:14,520 and heads out through the heliosphere 719 00:34:20,700 --> 00:34:18,250 yeah our next Twitter question so if 720 00:34:23,360 --> 00:34:20,710 iris doesn't have any fuel can someone 721 00:34:29,790 --> 00:34:23,370 help explain how it moves about in space 722 00:34:35,340 --> 00:34:29,800 yes that's really fun ah iris has 723 00:34:39,419 --> 00:34:35,350 launched slightly tilted with respect to 724 00:34:42,930 --> 00:34:39,429 the rotation axis of the earth and if 725 00:34:47,100 --> 00:34:42,940 you think about it a little bit ah that 726 00:34:53,090 --> 00:34:47,110 if you just launched around the earth as 727 00:34:55,950 --> 00:34:53,100 the earth went around the Sun in only a 728 00:34:58,440 --> 00:34:55,960 quarter of a year you'd be in darkness 729 00:35:01,530 --> 00:34:58,450 all the time but the earth isn't a 730 00:35:04,760 --> 00:35:01,540 perfect sphere it's a little bit fatter 731 00:35:08,760 --> 00:35:04,770 in the middle like some of us ah and 732 00:35:14,700 --> 00:35:08,770 because of that it exists it exerts a 733 00:35:18,060 --> 00:35:14,710 force on the orbit and as a result the 734 00:35:20,250 --> 00:35:18,070 orbit of trace revolves once around the 735 00:35:24,780 --> 00:35:20,260 earth every time the earth resolves 736 00:35:26,640 --> 00:35:24,790 around the Sun and whoever people have 737 00:35:31,440 --> 00:35:26,650 figured out exactly where you put a 738 00:35:33,810 --> 00:35:31,450 satellite to do that okay have a 739 00:35:36,000 --> 00:35:33,820 question we received before we went on 740 00:35:38,310 --> 00:35:36,010 the air will iris conduct a survey of 741 00:35:40,680 --> 00:35:38,320 the entire Sun one small bit 742 00:35:45,570 --> 00:35:40,690 a time or will it target only special 743 00:35:49,530 --> 00:35:45,580 areas of the Sun ah it's a focused 744 00:35:53,810 --> 00:35:49,540 mission it'll target special areas of 745 00:35:59,610 --> 00:35:53,820 the Sun and won't attempt to make maps 746 00:36:05,060 --> 00:35:59,620 of the Sun we have a mission that does 747 00:36:07,860 --> 00:36:05,070 that sto and so we don't need to do that 748 00:36:10,290 --> 00:36:07,870 ok one other question why are you 749 00:36:13,070 --> 00:36:10,300 launching iris on a Pegasus rocket 750 00:36:18,660 --> 00:36:13,080 instead of a conventional vertical Rock 751 00:36:20,340 --> 00:36:18,670 cheaper but also had met the mission 752 00:36:22,350 --> 00:36:20,350 requirements that we I mean we designed 753 00:36:24,450 --> 00:36:22,360 this meets the mission requirements 754 00:36:28,050 --> 00:36:24,460 there are a number of assets that do 755 00:36:33,120 --> 00:36:28,060 launch spacecraft at this size and NASA 756 00:36:35,580 --> 00:36:33,130 has a as a methodology that is set out 757 00:36:38,460 --> 00:36:35,590 for each of our missions to to to 758 00:36:39,810 --> 00:36:38,470 optimize that mission with with their 759 00:36:43,800 --> 00:36:39,820 launch vehicle available at that time 760 00:36:47,610 --> 00:36:43,810 and for iris it was we're very happy to 761 00:36:49,880 --> 00:36:47,620 be launching on an orbital Pegasus okay 762 00:36:52,680 --> 00:36:49,890 we have one last question at this point 763 00:36:54,150 --> 00:36:52,690 those fine structures that was shown in 764 00:36:58,700 --> 00:36:54,160 the previous graphics what are those 765 00:37:05,600 --> 00:36:58,710 made of they're made out of solar stuff 766 00:37:10,740 --> 00:37:05,610 which is which is sort of eighty percent 767 00:37:16,490 --> 00:37:10,750 hydrogen and about eighteen or nineteen 768 00:37:20,490 --> 00:37:16,500 percent helium and one or two percent of 769 00:37:24,120 --> 00:37:20,500 everything else all the elements that we 770 00:37:26,880 --> 00:37:24,130 find on earth in at the level of one or 771 00:37:30,630 --> 00:37:26,890 two percent but it's mostly hydrogen 772 00:37:32,430 --> 00:37:30,640 with a little bit of helium okay thank 773 00:37:33,900 --> 00:37:32,440 you well that's of all the questions we 774 00:37:36,570 --> 00:37:33,910 have for today I wanted to remind 775 00:37:39,750 --> 00:37:36,580 everyone that they can follow along iris 776 00:37:43,710 --> 00:37:39,760 online through social media on NASA's on 777 00:37:45,510 --> 00:37:43,720 quite a few social media channels also 778 00:37:48,830 --> 00:37:45,520 as a reminder the graphics that you've 779 00:37:51,569 --> 00:37:48,840 seen today are all available online at 780 00:37:55,289 --> 00:37:51,579 geo nasa gov 781 00:37:57,239 --> 00:37:55,299 / iris graphics and please continue to 782 00:37:58,829 --> 00:37:57,249 follow the mission online all the way up 783 00:38:00,329 --> 00:37:58,839 through launch and it's interesting 784 00:38:06,449 --> 00:38:00,339 findings that will be coming up over the 785 00:38:08,670 --> 00:38:06,459 next few years at ww na sa gov / iris
