1 00:00:08,150 --> 00:00:05,030 good afternoon and welcome to nasa's 2 00:00:10,629 --> 00:00:08,160 wide-field infrared survey explorer also 3 00:00:13,350 --> 00:00:10,639 known as wise pre-launch news conference 4 00:00:15,270 --> 00:00:13,360 from vandenberg air force base 5 00:00:17,189 --> 00:00:15,280 joining us today are 6 00:00:21,750 --> 00:00:17,199 john morse director of nasa's 7 00:00:27,910 --> 00:00:23,429 chuck de val 8 00:00:34,870 --> 00:00:30,550 vernon thorpe united launch alliance 9 00:00:34,880 --> 00:00:39,910 bill iris wise project manager 10 00:00:46,310 --> 00:00:42,470 and captain andrew fry launch weather 11 00:00:48,229 --> 00:00:46,320 officer 30th space wing 12 00:00:50,229 --> 00:00:48,239 we'll begin with some opening statements 13 00:00:51,750 --> 00:00:50,239 and then take your questions 14 00:00:53,670 --> 00:00:51,760 john 15 00:00:56,069 --> 00:00:53,680 thanks tracy 16 00:00:57,910 --> 00:00:56,079 what i'd like to do is 17 00:00:58,869 --> 00:00:57,920 run over the broader context of the wise 18 00:01:01,830 --> 00:00:58,879 mission 19 00:01:04,149 --> 00:01:01,840 and uh also talk about at a top level 20 00:01:06,070 --> 00:01:04,159 its science objectives and to remind you 21 00:01:06,789 --> 00:01:06,080 that there is a science briefing coming 22 00:01:08,789 --> 00:01:06,799 up 23 00:01:10,710 --> 00:01:08,799 after this briefing 24 00:01:13,030 --> 00:01:10,720 uh let's get right to it and go to the 25 00:01:15,749 --> 00:01:13,040 first graphic and show the at nasa's 26 00:01:17,749 --> 00:01:15,759 astrophysics mission portfolio as it 27 00:01:19,910 --> 00:01:17,759 stands right now 28 00:01:21,030 --> 00:01:19,920 we have hubble chandra and spitzer along 29 00:01:23,590 --> 00:01:21,040 the bottom there those are great 30 00:01:24,870 --> 00:01:23,600 observatories we also have kepler in the 31 00:01:27,830 --> 00:01:24,880 lower left 32 00:01:29,910 --> 00:01:27,840 which launched in march of this year and 33 00:01:32,149 --> 00:01:29,920 fermi in the upper right 34 00:01:34,469 --> 00:01:32,159 which launched last year 35 00:01:36,630 --> 00:01:34,479 both returning their science results 36 00:01:39,590 --> 00:01:36,640 there are five internationally led 37 00:01:42,389 --> 00:01:39,600 missions on which nasa is a partner 38 00:01:46,789 --> 00:01:42,399 and we also have four explorer missions 39 00:01:50,950 --> 00:01:49,830 and the explorer program is 40 00:01:52,630 --> 00:01:50,960 one of our 41 00:01:54,389 --> 00:01:52,640 most important aspects of our flight 42 00:01:56,709 --> 00:01:54,399 program and it does 43 00:01:59,190 --> 00:01:56,719 entail the smaller missions 44 00:02:02,069 --> 00:01:59,200 along with the larger missions 45 00:02:04,230 --> 00:02:02,079 like hubble spitzer and chandra now 46 00:02:06,789 --> 00:02:04,240 these missions cover the entire 47 00:02:08,790 --> 00:02:06,799 electromagnetic spectrum 48 00:02:10,949 --> 00:02:08,800 now if we go to the next 49 00:02:13,270 --> 00:02:10,959 graphic 50 00:02:15,190 --> 00:02:13,280 we see that we're adding y's and why is 51 00:02:17,270 --> 00:02:15,200 it shown here not because it's very 52 00:02:18,949 --> 00:02:17,280 large but in order to emphasize its 53 00:02:20,949 --> 00:02:18,959 newness 54 00:02:23,110 --> 00:02:20,959 wise joins the largest fleet of 55 00:02:24,390 --> 00:02:23,120 astrophysics missions that has ever been 56 00:02:25,990 --> 00:02:24,400 flown 57 00:02:28,550 --> 00:02:26,000 and that astronomers will use to make 58 00:02:31,110 --> 00:02:28,560 new discoveries now wise is a 40 59 00:02:34,550 --> 00:02:31,120 centimeter telescope it's cryogenically 60 00:02:36,790 --> 00:02:34,560 cooled to minus 430 degrees fahrenheit 61 00:02:37,910 --> 00:02:36,800 it has four state-of-the-art infrared 62 00:02:40,309 --> 00:02:37,920 detectors 63 00:02:43,670 --> 00:02:40,319 it'll take over a million images during 64 00:02:45,670 --> 00:02:43,680 the course of its 10-month mission 65 00:02:47,190 --> 00:02:45,680 and so now why don't we contrast a 66 00:02:49,830 --> 00:02:47,200 little bit between the visible in the 67 00:02:52,229 --> 00:02:49,840 infrared and and begin to delve into why 68 00:02:53,509 --> 00:02:52,239 we're doing wise on the next graphic 69 00:02:56,550 --> 00:02:53,519 what we see 70 00:02:58,390 --> 00:02:56,560 is how the milky way and the the sky 71 00:03:01,030 --> 00:02:58,400 which is centered on the milky way 72 00:03:02,470 --> 00:03:01,040 appears to the visible eye the milky way 73 00:03:04,149 --> 00:03:02,480 is the band across the middle it's 74 00:03:06,550 --> 00:03:04,159 diffuse you could see the galactic 75 00:03:09,270 --> 00:03:06,560 center in the middle and there's other 76 00:03:12,390 --> 00:03:09,280 galaxies like the magellanic clouds 77 00:03:15,430 --> 00:03:12,400 those smudges on the lower part this map 78 00:03:17,990 --> 00:03:15,440 is dominated essentially by starlight 79 00:03:20,070 --> 00:03:18,000 and you see how patchy the milky way 80 00:03:23,110 --> 00:03:20,080 appears due to the 81 00:03:24,630 --> 00:03:23,120 obscuring dust that 82 00:03:26,229 --> 00:03:24,640 permeates the 83 00:03:28,390 --> 00:03:26,239 the galaxy 84 00:03:29,910 --> 00:03:28,400 however in the infrared on the next 85 00:03:32,869 --> 00:03:29,920 graphic 86 00:03:34,710 --> 00:03:32,879 we see how much different the sky 87 00:03:37,190 --> 00:03:34,720 appears in the infrared and this is a 88 00:03:38,550 --> 00:03:37,200 new tool for astronomers to use in order 89 00:03:40,390 --> 00:03:38,560 to 90 00:03:42,869 --> 00:03:40,400 examine the cosmos 91 00:03:45,430 --> 00:03:42,879 now this infrared map shows how the 92 00:03:47,910 --> 00:03:45,440 milky way is a very flat disc where 93 00:03:49,990 --> 00:03:47,920 material concentrates 94 00:03:52,710 --> 00:03:50,000 and then you can see the tenuous clouds 95 00:03:54,869 --> 00:03:52,720 some nearby some far away 96 00:03:56,390 --> 00:03:54,879 which are the sites where new stars are 97 00:03:58,229 --> 00:03:56,400 forming 98 00:04:01,110 --> 00:03:58,239 so in summary 99 00:04:03,910 --> 00:04:01,120 this new sky map that wise will generate 100 00:04:06,630 --> 00:04:03,920 is hundreds of times more sensitive than 101 00:04:08,390 --> 00:04:06,640 the previous maps it will represent the 102 00:04:10,550 --> 00:04:08,400 infrared mother lode 103 00:04:12,309 --> 00:04:10,560 that astronomers will mine 104 00:04:13,670 --> 00:04:12,319 for the years to come 105 00:04:15,830 --> 00:04:13,680 and then they'll be able to go through 106 00:04:17,670 --> 00:04:15,840 this map identify interesting targets 107 00:04:20,069 --> 00:04:17,680 for follow-up observations with 108 00:04:21,030 --> 00:04:20,079 observatories such as spitzer 109 00:04:23,830 --> 00:04:21,040 hubble 110 00:04:25,990 --> 00:04:23,840 herschel and eventually sophia which is 111 00:04:28,629 --> 00:04:26,000 in the air right now i might point out 112 00:04:30,550 --> 00:04:28,639 and also the james webb space telescope 113 00:04:32,710 --> 00:04:30,560 which will be launched in the middle of 114 00:04:33,909 --> 00:04:32,720 the next decade and so with that let me 115 00:04:37,110 --> 00:04:33,919 turn it over 116 00:04:39,830 --> 00:04:38,469 thanks john 117 00:04:42,310 --> 00:04:39,840 good afternoon 118 00:04:44,230 --> 00:04:42,320 i'm i'm proud and privileged to be here 119 00:04:46,070 --> 00:04:44,240 today representing the men and women of 120 00:04:47,909 --> 00:04:46,080 the launch services program 121 00:04:50,070 --> 00:04:47,919 i can tell you that the the launch team 122 00:04:52,710 --> 00:04:50,080 is ready we have been through all of the 123 00:04:53,749 --> 00:04:52,720 of nasa's reviews we do have one review 124 00:04:54,710 --> 00:04:53,759 remaining 125 00:04:56,710 --> 00:04:54,720 tomorrow morning we're going to meet 126 00:04:58,550 --> 00:04:56,720 with the air force and get a 127 00:05:01,430 --> 00:04:58,560 go hopefully 128 00:05:04,390 --> 00:05:01,440 from the wing commander 129 00:05:06,629 --> 00:05:04,400 but we have a busy next 40 hours and 130 00:05:09,029 --> 00:05:06,639 i'll touch on that a little bit but what 131 00:05:10,629 --> 00:05:09,039 i wanted to describe today 132 00:05:12,550 --> 00:05:10,639 is how we got to this point i have a 133 00:05:14,629 --> 00:05:12,560 video depicting some of the processing 134 00:05:17,590 --> 00:05:14,639 milestones that we've 135 00:05:19,430 --> 00:05:17,600 achieved so far if we can roll into that 136 00:05:20,469 --> 00:05:19,440 this shows the booster being hoisted 137 00:05:22,070 --> 00:05:20,479 into the 138 00:05:22,830 --> 00:05:22,080 mobile service tower there's a shot of 139 00:05:25,110 --> 00:05:22,840 the 140 00:05:26,629 --> 00:05:25,120 rs-27 main engine 141 00:05:29,510 --> 00:05:26,639 that provides about two hundred thousand 142 00:05:31,350 --> 00:05:29,520 pounds of thrust at liftoff 143 00:05:34,390 --> 00:05:31,360 this is a shot of the inner stage which 144 00:05:36,790 --> 00:05:34,400 rests atop the booster 145 00:05:39,029 --> 00:05:36,800 it helps 146 00:05:41,990 --> 00:05:39,039 span the first and second stage the 147 00:05:44,230 --> 00:05:42,000 second stage will be hoisted and uh set 148 00:05:46,790 --> 00:05:44,240 in between that where you the engine 149 00:05:49,510 --> 00:05:46,800 belt will reside in that inner stage 150 00:05:52,070 --> 00:05:49,520 here's one of three solid rocket motors 151 00:05:54,870 --> 00:05:52,080 being hoisted up this this uh 152 00:05:57,350 --> 00:05:54,880 configuration is a 7300 where we have 153 00:05:59,670 --> 00:05:57,360 three groundlet solid motors built by 154 00:06:01,430 --> 00:05:59,680 alliant tech systems 155 00:06:03,909 --> 00:06:01,440 that's the second stage coming in this 156 00:06:07,830 --> 00:06:03,919 was on october 23rd 157 00:06:09,510 --> 00:06:07,840 it's got an aerojet engine 158 00:06:11,990 --> 00:06:09,520 for this mission that engine will burn 159 00:06:13,270 --> 00:06:12,000 twice in order to get wise and into its 160 00:06:15,029 --> 00:06:13,280 proper orbit 161 00:06:16,469 --> 00:06:15,039 there it is setting down 162 00:06:18,070 --> 00:06:16,479 into that inner stage if you can 163 00:06:20,390 --> 00:06:18,080 visualize that 164 00:06:23,749 --> 00:06:20,400 here's the spacecraft canned up 165 00:06:25,830 --> 00:06:23,759 rolling out on november 20th 166 00:06:28,469 --> 00:06:25,840 spacecraft weighs about four fourteen 167 00:06:31,670 --> 00:06:28,479 hundred and sixty pounds 168 00:06:33,430 --> 00:06:31,680 that's a direct-made adapter that allows 169 00:06:39,110 --> 00:06:33,440 the team to 170 00:06:43,270 --> 00:06:40,950 torque it down 171 00:06:45,670 --> 00:06:43,280 some of the 172 00:06:47,350 --> 00:06:45,680 the platforms allowed to move to bring 173 00:06:49,670 --> 00:06:47,360 the fairing the two halves of the 174 00:06:51,670 --> 00:06:49,680 fairing inn 175 00:06:53,510 --> 00:06:51,680 this was just before thanksgiving 176 00:06:55,510 --> 00:06:53,520 there's a shot of the spacecraft on top 177 00:06:58,550 --> 00:06:55,520 of the second stage with one half of the 178 00:07:02,390 --> 00:07:00,790 obviously in a clean room environment 179 00:07:05,270 --> 00:07:02,400 with wise's telescope 180 00:07:06,870 --> 00:07:05,280 and instrument it's uh it's vital to 181 00:07:08,390 --> 00:07:06,880 keep that area 182 00:07:12,550 --> 00:07:08,400 in a clean room 183 00:07:15,189 --> 00:07:12,560 environment and there's the launch decal 184 00:07:17,909 --> 00:07:15,199 so going into the next 40 hours 185 00:07:20,070 --> 00:07:17,919 starting tomorrow morning we do have the 186 00:07:21,110 --> 00:07:20,080 range review as i mentioned following 187 00:07:22,790 --> 00:07:21,120 that 188 00:07:24,550 --> 00:07:22,800 because we are going to hear we've got 189 00:07:26,469 --> 00:07:24,560 some challenging weather ahead of us 190 00:07:28,830 --> 00:07:26,479 we're going to have one last tag up and 191 00:07:31,749 --> 00:07:28,840 see what the forecast for friday would 192 00:07:33,110 --> 00:07:31,759 bring this will allow the wise 193 00:07:35,430 --> 00:07:33,120 spacecraft to 194 00:07:37,990 --> 00:07:35,440 disconnect their cryogenic operations 195 00:07:40,309 --> 00:07:38,000 and and commit to launch so if we are 196 00:07:42,469 --> 00:07:40,319 successful with that we do have another 197 00:07:44,469 --> 00:07:42,479 weather weather brief at 3 30 tomorrow 198 00:07:48,390 --> 00:07:44,479 afternoon which will allow the 199 00:07:51,110 --> 00:07:48,400 mobile service tower to retract back 200 00:07:52,790 --> 00:07:51,120 we plan to do an early fuel load into 201 00:07:54,869 --> 00:07:52,800 the first stage 202 00:07:57,110 --> 00:07:54,879 that plan is for 7 pm 203 00:08:00,469 --> 00:07:57,120 tomorrow evening versus doing it during 204 00:08:02,550 --> 00:08:00,479 the countdown on friday that aids in 205 00:08:04,790 --> 00:08:02,560 winds if we if we were to have high 206 00:08:06,150 --> 00:08:04,800 winds having that stability in the 207 00:08:06,950 --> 00:08:06,160 booster helps 208 00:08:10,150 --> 00:08:06,960 us 209 00:08:12,309 --> 00:08:10,160 handle a higher wind condition 210 00:08:15,110 --> 00:08:12,319 given all that the tower would be rolled 211 00:08:16,390 --> 00:08:15,120 back at 8 30 between 8 30 and 10 30 212 00:08:19,029 --> 00:08:16,400 tomorrow evening 213 00:08:21,029 --> 00:08:19,039 so if we get past those we start on 214 00:08:24,070 --> 00:08:21,039 console friday morning the management 215 00:08:26,230 --> 00:08:24,080 will come on at two in the morning 216 00:08:27,350 --> 00:08:26,240 we are in a 60-minute built-in hold at 217 00:08:29,270 --> 00:08:27,360 that point 218 00:08:32,870 --> 00:08:29,280 we then transition into our terminal 219 00:08:35,430 --> 00:08:32,880 count for the final three hours 220 00:08:36,630 --> 00:08:35,440 we have one more weather brief that says 221 00:08:38,709 --> 00:08:36,640 we are 222 00:08:40,550 --> 00:08:38,719 able and willing to load liquid oxygen 223 00:08:41,990 --> 00:08:40,560 into the first stage that's at t minus 224 00:08:43,670 --> 00:08:42,000 75 minutes 225 00:08:45,910 --> 00:08:43,680 if we get past that 226 00:08:48,150 --> 00:08:45,920 we do an engine slew check with 30 227 00:08:50,630 --> 00:08:48,160 minutes to go we have planned built-in 228 00:08:53,030 --> 00:08:50,640 holds if we get behind in the count we 229 00:08:58,070 --> 00:08:53,040 can use those to make sure we hit the 230 00:09:01,910 --> 00:08:58,080 zero t zero is 609 33 pacific time we've 231 00:09:04,470 --> 00:09:01,920 got a 14 minute 18 second window 232 00:09:06,310 --> 00:09:04,480 we have on the range the 11th and the 233 00:09:08,310 --> 00:09:06,320 12th if we need it 234 00:09:10,470 --> 00:09:08,320 and you'll probably hear from bill iris 235 00:09:11,509 --> 00:09:10,480 how complex this mission is 236 00:09:14,070 --> 00:09:11,519 so 237 00:09:16,949 --> 00:09:14,080 we have a two days on two is it two days 238 00:09:18,630 --> 00:09:16,959 off kind of of posture so if we were to 239 00:09:20,470 --> 00:09:18,640 count down and not make the 11th and 240 00:09:22,389 --> 00:09:20,480 12th we'd we would have to stand down 241 00:09:25,750 --> 00:09:22,399 for the 13th and 14th 242 00:09:28,870 --> 00:09:25,760 let them go do some cryogenic operations 243 00:09:29,990 --> 00:09:28,880 and we'd be back after that so uh it's 244 00:09:38,070 --> 00:09:30,000 uh 245 00:09:39,350 --> 00:09:38,080 through our next 40 hours and looking 246 00:09:41,190 --> 00:09:39,360 very much forward to it i'll turn it 247 00:09:46,470 --> 00:09:41,200 back over to tracy 248 00:09:50,630 --> 00:09:47,829 afternoon 249 00:09:52,710 --> 00:09:50,640 united launch alliance is proud to be a 250 00:09:54,550 --> 00:09:52,720 supporting mission for supporting nasa 251 00:09:56,710 --> 00:09:54,560 for the launch of the wise mission this 252 00:09:58,870 --> 00:09:56,720 will be our seventh nasa launch of the 253 00:10:00,949 --> 00:09:58,880 year coming on the heels of some other 254 00:10:03,990 --> 00:10:00,959 well-known missions like noaa n-prime 255 00:10:05,750 --> 00:10:04,000 kepler lro l cross and we've also 256 00:10:07,910 --> 00:10:05,760 supported nasa on some missile defense 257 00:10:09,990 --> 00:10:07,920 agency missions this year as well 258 00:10:12,630 --> 00:10:10,000 and this is a great time to be part of 259 00:10:15,030 --> 00:10:12,640 ula just last week we launched a delta 260 00:10:16,790 --> 00:10:15,040 iv from the cape we launched the wgs3 261 00:10:19,509 --> 00:10:16,800 mission for the air force and that 262 00:10:21,509 --> 00:10:19,519 marked our 36th launch in 36 months 263 00:10:22,389 --> 00:10:21,519 since ula was formed 264 00:10:26,389 --> 00:10:22,399 uh 265 00:10:29,269 --> 00:10:26,399 in the next few days will actually be 266 00:10:31,269 --> 00:10:29,279 the 37th mission in 36 months we have 267 00:10:33,829 --> 00:10:31,279 until december 14th to achieve that 268 00:10:35,910 --> 00:10:33,839 milestone because december 14th of 2006 269 00:10:37,509 --> 00:10:35,920 was our first launch as united launch 270 00:10:39,430 --> 00:10:37,519 alliance 271 00:10:42,150 --> 00:10:39,440 the credit for all that goes to all of 272 00:10:44,069 --> 00:10:42,160 the incredible people at ula as well as 273 00:10:45,509 --> 00:10:44,079 our government partners like nasa who 274 00:10:47,190 --> 00:10:45,519 support us on all these challenging 275 00:10:49,030 --> 00:10:47,200 missions 276 00:10:50,630 --> 00:10:49,040 we've been using our entire launch 277 00:10:52,630 --> 00:10:50,640 vehicle family all three of our families 278 00:10:54,710 --> 00:10:52,640 over the last uh three years we've been 279 00:10:56,550 --> 00:10:54,720 launching delta fours and delta twos and 280 00:10:57,670 --> 00:10:56,560 atlas fives 281 00:11:01,110 --> 00:10:57,680 and that we've been launching off of 282 00:11:02,870 --> 00:11:01,120 both coasts as you know and i'm happy to 283 00:11:04,710 --> 00:11:02,880 say that more than a third of those 284 00:11:07,430 --> 00:11:04,720 missions have been performed on behalf 285 00:11:09,910 --> 00:11:07,440 of nasa counting wise 286 00:11:12,949 --> 00:11:09,920 14 out of 37 missions more than a third 287 00:11:15,590 --> 00:11:12,959 of them have been done on behalf of nasa 288 00:11:17,590 --> 00:11:15,600 in just 2009 alone we've launched eight 289 00:11:19,590 --> 00:11:17,600 delta twos four from the cape and four 290 00:11:21,990 --> 00:11:19,600 from vandenberg 291 00:11:24,069 --> 00:11:22,000 and uh i would now like to tell you 292 00:11:25,750 --> 00:11:24,079 briefly what tomorrow's flight profile 293 00:11:26,949 --> 00:11:25,760 or what friday's flight profile is going 294 00:11:29,590 --> 00:11:26,959 to look like 295 00:11:31,590 --> 00:11:29,600 we're using a delta ii 7320 296 00:11:33,990 --> 00:11:31,600 configuration that's a delta ii core 297 00:11:36,069 --> 00:11:34,000 with three srbs on the back end we have 298 00:11:37,350 --> 00:11:36,079 a 10 meter or a 10 foot composite 299 00:11:38,870 --> 00:11:37,360 payload fairing protecting the 300 00:11:41,350 --> 00:11:38,880 spacecraft 301 00:11:43,430 --> 00:11:41,360 and after liftoff the three solid motors 302 00:11:46,550 --> 00:11:43,440 will burn for about 99 seconds then 303 00:11:47,910 --> 00:11:46,560 we'll jettison those the central uh 304 00:11:49,590 --> 00:11:47,920 engine the core engine on the first 305 00:11:51,750 --> 00:11:49,600 stage will continue to burn until about 306 00:11:53,910 --> 00:11:51,760 four minutes into flight after we run on 307 00:11:55,990 --> 00:11:53,920 a propellant on that stage we'll 308 00:11:57,910 --> 00:11:56,000 separate from the second stage and will 309 00:12:00,710 --> 00:11:57,920 ignite the upper stage engine for the 310 00:12:02,629 --> 00:12:00,720 first of two burns 311 00:12:04,949 --> 00:12:02,639 about five minutes into flight during 312 00:12:06,470 --> 00:12:04,959 that first stage burn will jettison the 313 00:12:08,310 --> 00:12:06,480 payload fairing because we'll be clear 314 00:12:10,310 --> 00:12:08,320 of the atmosphere about five minutes 315 00:12:13,110 --> 00:12:10,320 later ten minutes in the flight we will 316 00:12:14,550 --> 00:12:13,120 complete our first stage burn or our 317 00:12:16,710 --> 00:12:14,560 first of the 318 00:12:19,269 --> 00:12:16,720 upper stage burns rather excuse me and 319 00:12:21,350 --> 00:12:19,279 then we have a 40 minute coast period 320 00:12:23,030 --> 00:12:21,360 following the end of the 40-minute coast 321 00:12:24,629 --> 00:12:23,040 we light the upper stage engines one 322 00:12:26,310 --> 00:12:24,639 more time very short burn only about 323 00:12:28,230 --> 00:12:26,320 eight and a half seconds 324 00:12:29,829 --> 00:12:28,240 and then we will 325 00:12:31,430 --> 00:12:29,839 use that burn to inject the wide 326 00:12:32,470 --> 00:12:31,440 spacecraft into the orbit it needs to 327 00:12:34,949 --> 00:12:32,480 get to 328 00:12:36,389 --> 00:12:34,959 and we'll separate the spacecraft from 329 00:12:37,990 --> 00:12:36,399 the launch vehicle 330 00:12:39,350 --> 00:12:38,000 just a little bit less than an hour into 331 00:12:42,470 --> 00:12:39,360 flight 332 00:12:46,230 --> 00:12:42,480 and that's all i have back to you tracy 333 00:12:48,389 --> 00:12:46,240 thank you now bill iris 334 00:12:50,790 --> 00:12:48,399 thank you tracy and vernon um it's 335 00:12:52,790 --> 00:12:50,800 pleasure for me to represent the wise 336 00:12:54,949 --> 00:12:52,800 project team 337 00:12:56,230 --> 00:12:54,959 jet propulsion laboratory ball aerospace 338 00:12:59,910 --> 00:12:56,240 corporation 339 00:13:00,949 --> 00:12:59,920 and the space dynamics lab have 340 00:13:02,550 --> 00:13:00,959 have 341 00:13:03,590 --> 00:13:02,560 gotten together to produce this 342 00:13:05,110 --> 00:13:03,600 beautiful 343 00:13:10,069 --> 00:13:05,120 instrument 344 00:13:12,629 --> 00:13:10,079 satellite is is ready to go that the 345 00:13:14,870 --> 00:13:12,639 flight team is ready to go and and that 346 00:13:17,430 --> 00:13:14,880 the uh operations team is ready to 347 00:13:19,829 --> 00:13:17,440 launch uh and operate wise 348 00:13:21,430 --> 00:13:19,839 uh it's gonna be a very busy time 349 00:13:23,590 --> 00:13:21,440 when that 350 00:13:25,670 --> 00:13:23,600 55-minute point after launch occurs for 351 00:13:28,230 --> 00:13:25,680 wise 352 00:13:30,389 --> 00:13:28,240 we will turn the satellite on at about 353 00:13:32,790 --> 00:13:30,399 six o'clock tomorrow morning 354 00:13:34,629 --> 00:13:32,800 do some software loads and some 355 00:13:36,470 --> 00:13:34,639 checkouts but we'll be sitting quietly 356 00:13:37,590 --> 00:13:36,480 waiting for the separation signal from 357 00:13:44,949 --> 00:13:37,600 the 358 00:13:47,590 --> 00:13:44,959 first thing we'll do is phone home 359 00:13:49,670 --> 00:13:47,600 we'll be in our uh our circular orbit 360 00:13:52,949 --> 00:13:49,680 and the y satellite has a low gain 361 00:13:55,829 --> 00:13:52,959 antenna that's uh shown up on top here 362 00:13:57,189 --> 00:13:55,839 that low gate antenna will communicate 363 00:14:00,470 --> 00:13:57,199 with the 364 00:14:02,550 --> 00:14:00,480 relay satellites above us and and 365 00:14:05,189 --> 00:14:02,560 they should acquire a signal fairly 366 00:14:07,670 --> 00:14:05,199 rapidly we expect anywhere from a couple 367 00:14:10,150 --> 00:14:07,680 of minutes to maybe five or ten minutes 368 00:14:11,990 --> 00:14:10,160 depending on how the y spacecraft is 369 00:14:15,110 --> 00:14:12,000 tumbling when it separates from the 370 00:14:18,069 --> 00:14:15,120 launch vehicle we expect it will tumble 371 00:14:19,509 --> 00:14:18,079 the satellite is going to be in a in a 372 00:14:22,069 --> 00:14:19,519 tumbling mode 373 00:14:24,389 --> 00:14:22,079 due to the fact that the separation 374 00:14:25,910 --> 00:14:24,399 system is not perfectly symmetrical we 375 00:14:28,550 --> 00:14:25,920 expect that and the software in the 376 00:14:31,110 --> 00:14:28,560 satellite is designed to cope with that 377 00:14:33,590 --> 00:14:31,120 its objective is eventually to take the 378 00:14:36,069 --> 00:14:33,600 solar panel and point it at the sun 379 00:14:38,230 --> 00:14:36,079 directly so that the batteries that have 380 00:14:40,310 --> 00:14:38,240 been discharged during the flight can be 381 00:14:42,629 --> 00:14:40,320 recharged 382 00:14:45,430 --> 00:14:42,639 about 20 minutes after launch 383 00:14:47,430 --> 00:14:45,440 another very important event occurs 384 00:14:49,910 --> 00:14:47,440 as as chuck indicated this is 385 00:14:51,990 --> 00:14:49,920 complicated it's not complicated for us 386 00:14:54,230 --> 00:14:52,000 because we're used to it but we have two 387 00:14:55,189 --> 00:14:54,240 solid hydrogen cryostats that contain 388 00:14:57,189 --> 00:14:55,199 about 389 00:15:00,389 --> 00:14:57,199 40 pounds of solid hydrogen they've been 390 00:15:02,949 --> 00:15:00,399 warming up for about a day and and we 391 00:15:06,150 --> 00:15:02,959 need to vent those tanks so that the 392 00:15:07,430 --> 00:15:06,160 telescope and the detectors that 393 00:15:09,750 --> 00:15:07,440 wise will use 394 00:15:12,310 --> 00:15:09,760 cool to their operational temperatures 395 00:15:14,470 --> 00:15:12,320 that will occur automatically at about 396 00:15:17,350 --> 00:15:14,480 20 minutes after launch 397 00:15:20,069 --> 00:15:17,360 and then we have one last important task 398 00:15:22,470 --> 00:15:20,079 to perform which is to get our bearings 399 00:15:23,350 --> 00:15:22,480 with respect to the the 400 00:15:26,069 --> 00:15:23,360 the 401 00:15:27,509 --> 00:15:26,079 visible sky in this case we have two 402 00:15:30,150 --> 00:15:27,519 star trackers 403 00:15:32,150 --> 00:15:30,160 on the back side of wise 404 00:15:34,470 --> 00:15:32,160 shown here 405 00:15:36,550 --> 00:15:34,480 see here over here one there and one 406 00:15:39,269 --> 00:15:36,560 there those star trackers will image the 407 00:15:42,310 --> 00:15:39,279 visible sky and they will determine 408 00:15:43,990 --> 00:15:42,320 where wise is pointed inertially and 409 00:15:46,069 --> 00:15:44,000 with our knowledge inside the computer 410 00:15:47,509 --> 00:15:46,079 we're going to be able to to to orient 411 00:15:49,350 --> 00:15:47,519 wise so that it 412 00:15:51,430 --> 00:15:49,360 faces directly out from the center of 413 00:15:53,910 --> 00:15:51,440 the earth and is in its final 414 00:15:55,670 --> 00:15:53,920 survey orientation in its orbit and i 415 00:15:57,670 --> 00:15:55,680 have an animation 416 00:15:59,910 --> 00:15:57,680 coming here which 417 00:16:02,470 --> 00:15:59,920 which illustrates that orbit 418 00:16:03,910 --> 00:16:02,480 uh there it is it also illustrates our 419 00:16:05,189 --> 00:16:03,920 model so you can see the various 420 00:16:07,430 --> 00:16:05,199 features of wise you see a lot of 421 00:16:09,590 --> 00:16:07,440 plumbing on the upper part of the of the 422 00:16:11,590 --> 00:16:09,600 instrument on top there that is part of 423 00:16:13,509 --> 00:16:11,600 our complication 424 00:16:15,990 --> 00:16:13,519 so here we are wise in orbit pointing 425 00:16:19,590 --> 00:16:16,000 outward scanning the sky in great 426 00:16:21,590 --> 00:16:19,600 circles repeatedly about 5700 pictures a 427 00:16:24,550 --> 00:16:21,600 day and this orbit was chosen and 428 00:16:26,550 --> 00:16:24,560 optimized specifically to do an all-sky 429 00:16:28,949 --> 00:16:26,560 survey in six months so that as you see 430 00:16:30,470 --> 00:16:28,959 as as the earth rotates around the sun 431 00:16:33,670 --> 00:16:30,480 the orbit plane 432 00:16:35,509 --> 00:16:33,680 rotates with it and and so that after 433 00:16:38,389 --> 00:16:35,519 six months the entire 434 00:16:40,470 --> 00:16:38,399 sky can be seen in this orbit and we 435 00:16:42,069 --> 00:16:40,480 will have completed an all-sky survey at 436 00:16:44,710 --> 00:16:42,079 that point in time 437 00:16:47,509 --> 00:16:44,720 so here we are we're oriented in orbit 438 00:16:49,430 --> 00:16:47,519 we've uh got our initial bearings but we 439 00:16:51,590 --> 00:16:49,440 still have lots to do this occurs after 440 00:16:53,030 --> 00:16:51,600 about a day 441 00:16:54,870 --> 00:16:53,040 there's another month of work to do 442 00:16:56,389 --> 00:16:54,880 before we can start our all-sky survey 443 00:16:57,749 --> 00:16:56,399 we'll start with a cover on the 444 00:16:59,430 --> 00:16:57,759 telescope 445 00:17:02,069 --> 00:16:59,440 to protect it from 446 00:17:04,230 --> 00:17:02,079 any possible deviations from the normal 447 00:17:06,710 --> 00:17:04,240 plan that we have we'll calibrate our 448 00:17:08,710 --> 00:17:06,720 attitude control system and we'll get 449 00:17:11,350 --> 00:17:08,720 comfortable with the sequences that we 450 00:17:15,029 --> 00:17:11,360 will use to eventually survey the sky 451 00:17:17,669 --> 00:17:15,039 after 16 days we'll remove the cover and 452 00:17:20,309 --> 00:17:17,679 uh and and expose 453 00:17:22,870 --> 00:17:20,319 the telescope of wise to the infrared 454 00:17:24,470 --> 00:17:22,880 sky that will require 455 00:17:26,630 --> 00:17:24,480 further calibrations this will be the 456 00:17:28,710 --> 00:17:26,640 first time the wise's eyes the eyes of 457 00:17:30,870 --> 00:17:28,720 wise will see the infrared sky and it 458 00:17:32,870 --> 00:17:30,880 will take about two weeks to get those 459 00:17:35,750 --> 00:17:32,880 calibrations completed 460 00:17:39,430 --> 00:17:35,760 after which time we will begin the 461 00:17:42,230 --> 00:17:39,440 the uh survey that wise will perform 462 00:17:43,430 --> 00:17:42,240 so i'm uh looking forward to this and we 463 00:17:46,710 --> 00:17:43,440 have a 464 00:17:48,870 --> 00:17:46,720 video couple videos to step back to the 465 00:17:51,750 --> 00:17:48,880 kind of our life here at vandenberg air 466 00:17:53,110 --> 00:17:51,760 force base for the last few months 467 00:17:55,190 --> 00:17:53,120 this video 468 00:17:57,029 --> 00:17:55,200 that you see now shows the flight 469 00:17:58,870 --> 00:17:57,039 payload adapter fitting 470 00:18:00,789 --> 00:17:58,880 being installed this is the actual 471 00:18:03,110 --> 00:18:00,799 hardware the little red hammers you see 472 00:18:04,950 --> 00:18:03,120 here is the separation plane between the 473 00:18:06,789 --> 00:18:04,960 spacecraft and the uh 474 00:18:09,029 --> 00:18:06,799 in the launch vehicle here you see wise 475 00:18:11,590 --> 00:18:09,039 when it arrived being lowered onto the 476 00:18:13,110 --> 00:18:11,600 separation springs that i referred to 477 00:18:15,990 --> 00:18:13,120 these are what's one of the three 478 00:18:18,789 --> 00:18:16,000 springs that separates the satellite 479 00:18:20,630 --> 00:18:18,799 from the launch vehicle and so there we 480 00:18:23,590 --> 00:18:20,640 have the flight 481 00:18:27,110 --> 00:18:23,600 spacecraft and its solar panels being 482 00:18:30,390 --> 00:18:27,120 mounted on the spacecraft the 483 00:18:33,029 --> 00:18:30,400 the our last step here at vandenberg air 484 00:18:34,549 --> 00:18:33,039 force base was to package wise into its 485 00:18:37,029 --> 00:18:34,559 uh flight 486 00:18:40,390 --> 00:18:37,039 transportation container and move it out 487 00:18:43,510 --> 00:18:40,400 to the launch pad and that was a pretty 488 00:18:46,630 --> 00:18:43,520 exciting event that i think is shown 489 00:18:48,710 --> 00:18:46,640 here in this video 490 00:18:52,070 --> 00:18:48,720 you see the container being lowered on 491 00:18:54,150 --> 00:18:52,080 top of of the double bagged spacecraft 492 00:18:56,230 --> 00:18:54,160 very carefully there's not a lot of room 493 00:18:58,390 --> 00:18:56,240 on the edge there so we've got lots of 494 00:18:59,430 --> 00:18:58,400 care being taken there 495 00:19:01,990 --> 00:18:59,440 um 496 00:19:04,470 --> 00:19:02,000 and uh there we are rolling out of the 497 00:19:06,950 --> 00:19:04,480 uh high bay here at vandenberg 498 00:19:09,029 --> 00:19:06,960 on our way to the launch pad so we're 499 00:19:10,470 --> 00:19:09,039 really excited about this it's uh you 500 00:19:13,190 --> 00:19:10,480 know it's a matter of 501 00:19:14,630 --> 00:19:13,200 just the weather now and uh captain fry 502 00:19:18,470 --> 00:19:14,640 is going to tell us how good the weather 503 00:19:22,230 --> 00:19:20,710 thank you 504 00:19:23,909 --> 00:19:22,240 i am the launch weather officer for 505 00:19:25,669 --> 00:19:23,919 delta ii wise the launch weather 506 00:19:27,669 --> 00:19:25,679 officer's job 507 00:19:29,909 --> 00:19:27,679 commonly called the elbow is to lead the 508 00:19:31,750 --> 00:19:29,919 lawn to other team to make the final 509 00:19:33,750 --> 00:19:31,760 make the go no-go call for weather we 510 00:19:35,669 --> 00:19:33,760 have constraints on both sides with the 511 00:19:38,230 --> 00:19:35,679 air force and the range side as well as 512 00:19:39,590 --> 00:19:38,240 a ula or customer side both are designed 513 00:19:41,430 --> 00:19:39,600 to protect the satellite and get it into 514 00:19:44,230 --> 00:19:41,440 orbit and to protect the public in 515 00:19:45,990 --> 00:19:44,240 general that the rocket is successful so 516 00:19:47,270 --> 00:19:46,000 we go to the satellite loop that we have 517 00:19:49,110 --> 00:19:47,280 currently 518 00:19:50,630 --> 00:19:49,120 right now you can see the weather on 519 00:19:52,070 --> 00:19:50,640 satellite rolling towards the central 520 00:19:53,669 --> 00:19:52,080 coast you can see a lot of the energy 521 00:19:55,669 --> 00:19:53,679 going up towards it towards the north 522 00:19:57,430 --> 00:19:55,679 but the entire band extends down well to 523 00:20:00,070 --> 00:19:57,440 the south and west and that's slowly 524 00:20:01,990 --> 00:20:00,080 making this approach towards vandenberg 525 00:20:04,070 --> 00:20:02,000 over the next next day or so it will 526 00:20:05,909 --> 00:20:04,080 continue its march and rain should start 527 00:20:08,390 --> 00:20:05,919 falling here at vandenberg tomorrow 528 00:20:10,149 --> 00:20:08,400 around noon or thereabouts and then 529 00:20:11,350 --> 00:20:10,159 we'll continue with light rain all 530 00:20:12,310 --> 00:20:11,360 through the count 531 00:20:14,149 --> 00:20:12,320 towards 532 00:20:16,870 --> 00:20:14,159 t0 533 00:20:19,270 --> 00:20:16,880 the launch forecast for tomorrow 534 00:20:21,590 --> 00:20:19,280 calls for thick clouds in the area and 535 00:20:23,110 --> 00:20:21,600 thick clouds is one of our constraints 536 00:20:24,630 --> 00:20:23,120 we're not allowed to launch a rocket 537 00:20:26,549 --> 00:20:24,640 that's uh through a cloud layer that's 538 00:20:29,510 --> 00:20:26,559 greater than or equal to 4 500 feet 539 00:20:31,750 --> 00:20:29,520 thick with temperatures between zero and 540 00:20:34,630 --> 00:20:31,760 minus 20 degrees celsius 541 00:20:36,549 --> 00:20:34,640 you can kill the loop now with those 542 00:20:38,549 --> 00:20:36,559 clouds moving our way even if the rain 543 00:20:40,630 --> 00:20:38,559 showers decrease or diminish those thick 544 00:20:42,149 --> 00:20:40,640 clouds will remain and that's our main 545 00:20:44,870 --> 00:20:42,159 area of concern we issue what's called a 546 00:20:47,669 --> 00:20:44,880 probability of violation or pov and a 547 00:20:49,350 --> 00:20:47,679 pov that tells us how likely we are to 548 00:20:51,029 --> 00:20:49,360 break our constraints how likely the 549 00:20:53,190 --> 00:20:51,039 weather is to 550 00:20:55,510 --> 00:20:53,200 negatively impact the mission 551 00:20:57,669 --> 00:20:55,520 our pov right now is 80 percent for 552 00:20:59,510 --> 00:20:57,679 those thick clouds some other associated 553 00:21:03,830 --> 00:20:59,520 constraints that we're worried about is 554 00:21:06,390 --> 00:21:03,840 called uh are are called 555 00:21:08,870 --> 00:21:06,400 disturbed weather which has to do with 556 00:21:10,230 --> 00:21:08,880 any kind of instability in the area 557 00:21:11,510 --> 00:21:10,240 we are worried about that with some 558 00:21:13,430 --> 00:21:11,520 moderate rain showers moderate rain 559 00:21:15,029 --> 00:21:13,440 showers are also a constraint any rain 560 00:21:16,710 --> 00:21:15,039 that will be above the 10 000 foot level 561 00:21:18,950 --> 00:21:16,720 is also a constraint 562 00:21:20,710 --> 00:21:18,960 luckily though delta ii in december are 563 00:21:22,789 --> 00:21:20,720 traditionally hampered by 564 00:21:24,070 --> 00:21:22,799 winds out here on the central coast at 565 00:21:26,310 --> 00:21:24,080 this time though the winds are looking 566 00:21:28,549 --> 00:21:26,320 to stay below the 20 knot level which is 567 00:21:30,950 --> 00:21:28,559 well below our constraint of 26 to 30 568 00:21:32,950 --> 00:21:30,960 knots for t0 so we're not looking for 569 00:21:34,630 --> 00:21:32,960 that problem however with this system 570 00:21:36,310 --> 00:21:34,640 it'll move through once it gets here 571 00:21:38,230 --> 00:21:36,320 it'll move through during the day on 572 00:21:40,310 --> 00:21:38,240 friday another system is quickly 573 00:21:42,149 --> 00:21:40,320 approaching behind that and that will 574 00:21:43,990 --> 00:21:42,159 cause problems for a possible 24 hour 575 00:21:46,310 --> 00:21:44,000 scrub if that were to occur 576 00:21:48,310 --> 00:21:46,320 if that 24-hour scrub occurs the same 577 00:21:49,510 --> 00:21:48,320 type of weather happens however you get 578 00:21:51,430 --> 00:21:49,520 the cold front type of weather that 579 00:21:54,149 --> 00:21:51,440 comes along with it a few cumulus clouds 580 00:21:55,350 --> 00:21:54,159 heavier rain showers and wind so you tie 581 00:21:58,230 --> 00:21:55,360 all those together and you have another 582 00:21:59,990 --> 00:21:58,240 80 probability of violation for saturday 583 00:22:01,270 --> 00:22:00,000 much of the same continues on sunday the 584 00:22:03,669 --> 00:22:01,280 weather finally starts to clear and 585 00:22:05,270 --> 00:22:03,679 break up for monday as ridging and high 586 00:22:07,350 --> 00:22:05,280 pressure move back into the central 587 00:22:09,029 --> 00:22:07,360 coast giving us fair skies and a light 588 00:22:11,350 --> 00:22:09,039 offshore breeze 589 00:22:12,549 --> 00:22:11,360 for monday and into tuesday but that's 590 00:22:14,390 --> 00:22:12,559 what we're worried about right now for 591 00:22:16,230 --> 00:22:14,400 delta ii wise the lunch weather team 592 00:22:17,750 --> 00:22:16,240 will be on console throughout the 593 00:22:19,909 --> 00:22:17,760 throughout the count evaluating all the 594 00:22:21,750 --> 00:22:19,919 weather data that's coming in and giving 595 00:22:23,990 --> 00:22:21,760 either the final go or the final no-go 596 00:22:25,430 --> 00:22:24,000 call for weather 597 00:22:27,190 --> 00:22:25,440 back to you tracy 598 00:22:29,510 --> 00:22:27,200 thank you we will now take questions 599 00:22:35,190 --> 00:22:29,520 please state your name and affiliation 600 00:22:39,430 --> 00:22:37,350 janine scully uh santa maria times alum 601 00:22:42,710 --> 00:22:39,440 poke record can you further explain when 602 00:22:44,630 --> 00:22:42,720 the clock starts on the 48 hours um with 603 00:22:49,430 --> 00:22:44,640 the wise constraint and 604 00:22:53,510 --> 00:22:51,830 uh yeah i'll take that uh 605 00:22:55,909 --> 00:22:53,520 you're you're talking about the 606 00:22:57,990 --> 00:22:55,919 cryogenic servicing constraint it's it 607 00:22:59,669 --> 00:22:58,000 starts when we disconnect the cryostat 608 00:23:01,190 --> 00:22:59,679 at about launch minus 609 00:23:02,549 --> 00:23:01,200 19 hours 610 00:23:04,390 --> 00:23:02,559 at that point 611 00:23:06,630 --> 00:23:04,400 we disconnect cooling 612 00:23:09,510 --> 00:23:06,640 helium cooling from from the cryostat 613 00:23:12,070 --> 00:23:09,520 and and the hydrogen and starts to warm 614 00:23:12,950 --> 00:23:12,080 and and we can allow it to warm for two 615 00:23:15,750 --> 00:23:12,960 days 616 00:23:17,909 --> 00:23:15,760 before we have to reconnect and cool it 617 00:23:20,950 --> 00:23:17,919 that cooling takes about two days so we 618 00:23:24,230 --> 00:23:20,960 have a two day on two day off two day on 619 00:23:26,789 --> 00:23:24,240 cycle which is not uh common for for a 620 00:23:29,029 --> 00:23:26,799 launch like this and so we're working 621 00:23:30,470 --> 00:23:29,039 with the nasa people to and ula people 622 00:23:32,230 --> 00:23:30,480 to get those 623 00:23:37,830 --> 00:23:32,240 cooling days on rainy days and the 624 00:23:42,390 --> 00:23:40,390 nora wallace santa barbara news press mr 625 00:23:44,390 --> 00:23:42,400 morse the the wow factor of the science 626 00:23:45,990 --> 00:23:44,400 and this seems pretty obvious when you 627 00:23:48,230 --> 00:23:46,000 start reading about it but can you 628 00:23:49,269 --> 00:23:48,240 explain in perhaps more layman's terms 629 00:23:50,870 --> 00:23:49,279 why 630 00:23:53,909 --> 00:23:50,880 this mission is so 631 00:23:55,269 --> 00:23:53,919 important for people on the ground 632 00:23:57,909 --> 00:23:55,279 not sure 633 00:23:59,029 --> 00:23:57,919 we'll we'll start with the importance of 634 00:24:01,750 --> 00:23:59,039 the 635 00:24:03,669 --> 00:24:01,760 infrared band to to begin with and in 636 00:24:05,590 --> 00:24:03,679 fact i would encourage you to make sure 637 00:24:08,230 --> 00:24:05,600 if you're around to ask the scientists 638 00:24:10,310 --> 00:24:08,240 later they love to tell you about wow 639 00:24:12,870 --> 00:24:10,320 and uh 640 00:24:14,789 --> 00:24:12,880 the the infrared is important to us 641 00:24:17,350 --> 00:24:14,799 in astronomy because it it shows us 642 00:24:19,269 --> 00:24:17,360 where a lot of the cool things are in 643 00:24:21,510 --> 00:24:19,279 the universe things much cooler than 644 00:24:24,070 --> 00:24:21,520 than stars like the sun 645 00:24:26,070 --> 00:24:24,080 and as you saw in the sky maps the the 646 00:24:27,430 --> 00:24:26,080 universe looks much different 647 00:24:30,149 --> 00:24:27,440 uh when we're 648 00:24:31,669 --> 00:24:30,159 at infrared wavelengths and the wow 649 00:24:33,990 --> 00:24:31,679 factor wise is that we're going to go 650 00:24:36,470 --> 00:24:34,000 much much deeper a hundred hundred times 651 00:24:37,830 --> 00:24:36,480 deeper in in some wavelengths and even a 652 00:24:40,390 --> 00:24:37,840 thousand times deeper in other 653 00:24:42,870 --> 00:24:40,400 wavelengths than we've ever gone before 654 00:24:45,350 --> 00:24:42,880 we're going to see in the solar system 655 00:24:46,630 --> 00:24:45,360 uh a hundred thousand new asteroids or 656 00:24:47,830 --> 00:24:46,640 more 657 00:24:49,909 --> 00:24:47,840 we'll see 658 00:24:51,830 --> 00:24:49,919 new structures and targets in the milky 659 00:24:55,110 --> 00:24:51,840 way and we're going to see hundreds of 660 00:24:58,390 --> 00:24:55,120 millions of objects around the sky 661 00:25:00,390 --> 00:24:58,400 and open up the extra galactic 662 00:25:01,830 --> 00:25:00,400 full sky survey and this is going to 663 00:25:03,750 --> 00:25:01,840 support 664 00:25:05,750 --> 00:25:03,760 our other missions 665 00:25:07,830 --> 00:25:05,760 that we have up there flying now and 666 00:25:08,950 --> 00:25:07,840 we'll be flying in the future 667 00:25:11,110 --> 00:25:08,960 and so 668 00:25:13,110 --> 00:25:11,120 not only is wise going to be a fantastic 669 00:25:15,750 --> 00:25:13,120 science mission in itself but the 670 00:25:17,590 --> 00:25:15,760 support it will give to other missions 671 00:25:19,830 --> 00:25:17,600 in the future 672 00:25:21,669 --> 00:25:19,840 following a long legacy of 673 00:25:22,789 --> 00:25:21,679 previous sky surveys at other 674 00:25:24,789 --> 00:25:22,799 wavelengths 675 00:25:27,510 --> 00:25:24,799 is going to be fantastic for for 676 00:25:31,830 --> 00:25:27,520 astronomers to use so wise's legacy 677 00:25:31,840 --> 00:25:35,669 are there any further questions 678 00:25:39,669 --> 00:25:37,269 with no further questions this will 679 00:25:41,830 --> 00:25:39,679 conclude our pre-launch news conference 680 00:25:45,269 --> 00:25:41,840 our next event will be the wise mission 681 00:25:47,350 --> 00:25:45,279 science briefing scheduled at 1 45.
