00:00:07,680 10 6 00:00:11,509 --> 00:00:09,040 9 7 00:00:12,549 --> 00:00:11,519 ignition sequence start 8 00:00:13,509 --> 00:00:12,559 5 9 00:00:14,549 --> 00:00:13,519 4 10 00:00:15,509 --> 00:00:14,559 3 11 00:00:21,349 --> 00:00:15,519 2 12 00:00:26,630 --> 00:00:23,910 you're looking at the historic b test 13 00:00:29,189 --> 00:00:26,640 complex at nasa's stennis space center 14 00:00:31,990 --> 00:00:29,199 where we're about to do a second green 15 00:00:34,310 --> 00:00:32,000 run hot fire test firing up the core 16 00:00:35,670 --> 00:00:34,320 stage of our new space launch system 17 00:00:38,549 --> 00:00:35,680 rocket 18 00:00:40,389 --> 00:00:38,559 good afternoon i'm lee d'angelo 19 00:00:42,389 --> 00:00:40,399 this stage we're testing today will be 20 00:00:44,630 --> 00:00:42,399 part of the rocket which will soon 21 00:00:46,869 --> 00:00:44,640 launch from nasa's kennedy space center 22 00:00:49,590 --> 00:00:46,879 on the artemis 1 mission 23 00:00:52,229 --> 00:00:49,600 that launch will send an uncrewed orion 24 00:00:53,189 --> 00:00:52,239 spacecraft beyond the moon and back to 25 00:00:55,510 --> 00:00:53,199 earth 26 00:00:57,590 --> 00:00:55,520 it's the first flight of the artemis 27 00:01:00,549 --> 00:00:57,600 program which will return american 28 00:01:03,189 --> 00:01:00,559 astronauts to the moon and pave the way 29 00:01:05,670 --> 00:01:03,199 for exploration of mars 30 00:01:08,070 --> 00:01:05,680 the space launch system will be the most 31 00:01:10,390 --> 00:01:08,080 powerful rocket in the world and is the 32 00:01:13,270 --> 00:01:10,400 only rocket that can send the orion 33 00:01:17,030 --> 00:01:13,280 spacecraft astronauts and supplies 34 00:01:19,749 --> 00:01:17,040 safely beyond the moon in one launch 35 00:01:21,510 --> 00:01:19,759 now we first tested this core stage on 36 00:01:24,870 --> 00:01:21,520 january 16th 37 00:01:27,910 --> 00:01:24,880 that marked a major milestone firing all 38 00:01:30,550 --> 00:01:27,920 four rs-25 engines together for the 39 00:01:33,749 --> 00:01:30,560 first time for about a minute 40 00:01:36,710 --> 00:01:33,759 however it ended earlier than planned so 41 00:01:38,069 --> 00:01:36,720 nasa and boeing decided to do a second 42 00:01:40,310 --> 00:01:38,079 test 43 00:01:42,230 --> 00:01:40,320 teams have been working hard to get to 44 00:01:44,630 --> 00:01:42,240 this point and the test countdown 45 00:01:46,950 --> 00:01:44,640 actually started a couple of days ago 46 00:01:49,109 --> 00:01:46,960 here to update us on where things stand 47 00:01:51,429 --> 00:01:49,119 is nasa public affairs officer catherine 48 00:01:53,670 --> 00:01:51,439 hamilton and headquarters green run 49 00:01:56,950 --> 00:01:53,680 manager bill robel in one of our test 50 00:01:59,590 --> 00:01:56,960 control centers here catherine 51 00:02:01,910 --> 00:01:59,600 thanks lee we're inside a secondary test 52 00:02:03,590 --> 00:02:01,920 complex outside of the control room and 53 00:02:05,109 --> 00:02:03,600 we're listening in to provide you 54 00:02:07,190 --> 00:02:05,119 updates as the team progresses through 55 00:02:09,589 --> 00:02:07,200 their steps for this operation we 56 00:02:10,790 --> 00:02:09,599 believe we're within about 45 minutes of 57 00:02:13,190 --> 00:02:10,800 the hot fire 58 00:02:16,070 --> 00:02:13,200 the team actually started two days ago 59 00:02:17,510 --> 00:02:16,080 powering up the avionics on march 16th 60 00:02:19,910 --> 00:02:17,520 and they checked out all the systems 61 00:02:21,910 --> 00:02:19,920 that they had tested on previous tests 62 00:02:24,869 --> 00:02:21,920 earlier this morning they conducted a go 63 00:02:26,949 --> 00:02:24,879 no-go poll to proceed into the test and 64 00:02:28,710 --> 00:02:26,959 i have bill robel here with me to tell 65 00:02:30,229 --> 00:02:28,720 us a little bit more bill can you tell 66 00:02:31,910 --> 00:02:30,239 us about how the operations have 67 00:02:33,910 --> 00:02:31,920 progressed today 68 00:02:35,910 --> 00:02:33,920 yeah sure will so 69 00:02:38,550 --> 00:02:35,920 at this point we've been in uh kind of 70 00:02:41,670 --> 00:02:38,560 replenish mold mode for both the liquid 71 00:02:44,869 --> 00:02:41,680 oxygen and liquid oxygen liquid hydrogen 72 00:02:47,509 --> 00:02:44,879 we've got at this point 540 000 gallons 73 00:02:50,229 --> 00:02:47,519 of liquid hydrogen on board and another 74 00:02:51,110 --> 00:02:50,239 200 000 gallons of liquid oxygen on 75 00:02:52,710 --> 00:02:51,120 board 76 00:02:54,710 --> 00:02:52,720 and they're in the conditioning process 77 00:02:56,470 --> 00:02:54,720 right now we're trying to get that uh 78 00:02:57,990 --> 00:02:56,480 temperature down as low as we can get it 79 00:02:58,710 --> 00:02:58,000 within the start box 80 00:03:00,149 --> 00:02:58,720 uh 81 00:03:01,990 --> 00:03:00,159 and we're also doing the same thing on 82 00:03:04,149 --> 00:03:02,000 the engine side of things 83 00:03:05,910 --> 00:03:04,159 and what's important about all of this 84 00:03:07,110 --> 00:03:05,920 is that you know this timeline that 85 00:03:09,509 --> 00:03:07,120 we're going through here will help 86 00:03:11,830 --> 00:03:09,519 inform the operations that'll take place 87 00:03:13,110 --> 00:03:11,840 down at kennedy space center where not 88 00:03:14,710 --> 00:03:13,120 only do they have these things to worry 89 00:03:16,710 --> 00:03:14,720 about but then they've also got to do 90 00:03:18,550 --> 00:03:16,720 things where they're getting people on 91 00:03:19,910 --> 00:03:18,560 board and taking care of all the other 92 00:03:21,670 --> 00:03:19,920 extraneous things that they have to do 93 00:03:23,910 --> 00:03:21,680 down there 94 00:03:25,589 --> 00:03:23,920 so for for us here right we've also been 95 00:03:27,750 --> 00:03:25,599 monitoring things like the battery 96 00:03:29,350 --> 00:03:27,760 charging uh they're they're basically up 97 00:03:31,990 --> 00:03:29,360 to speed at this point 98 00:03:33,910 --> 00:03:32,000 and then we've got the the redundant 99 00:03:35,990 --> 00:03:33,920 inertial navigation unit 100 00:03:38,229 --> 00:03:36,000 wet checkout which is basically you know 101 00:03:39,830 --> 00:03:38,239 mounted up in the lox dome area and so 102 00:03:41,190 --> 00:03:39,840 they're looking to see how it behaves 103 00:03:42,630 --> 00:03:41,200 relative to the low temperatures that 104 00:03:44,309 --> 00:03:42,640 we're seeing now in that in that 105 00:03:46,229 --> 00:03:44,319 compartment 106 00:03:47,750 --> 00:03:46,239 and so at this point too the teams are 107 00:03:49,910 --> 00:03:47,760 basically looking at all their data 108 00:03:51,750 --> 00:03:49,920 making sure that uh their systems are 109 00:03:53,990 --> 00:03:51,760 are where they're supposed to be 110 00:03:57,990 --> 00:03:54,000 uh and ready to go for uh proceeding 111 00:04:01,750 --> 00:03:59,750 thanks bill and can you tell us a bit 112 00:04:04,869 --> 00:04:01,760 how the timeline is different for 113 00:04:06,470 --> 00:04:04,879 today's test than uh for uh for launch 114 00:04:08,630 --> 00:04:06,480 and how is determining the time of the 115 00:04:11,110 --> 00:04:08,640 hot fire different from you know setting 116 00:04:13,110 --> 00:04:11,120 the time for a launch 117 00:04:15,030 --> 00:04:13,120 yeah so for us it's it's actually uh 118 00:04:16,469 --> 00:04:15,040 we're in a pretty good spot we're trying 119 00:04:18,870 --> 00:04:16,479 to at this point 120 00:04:21,110 --> 00:04:18,880 uh maximize the amount of commodities 121 00:04:21,990 --> 00:04:21,120 that we've got here in the test facility 122 00:04:22,710 --> 00:04:22,000 so 123 00:04:23,990 --> 00:04:22,720 uh 124 00:04:26,230 --> 00:04:24,000 we're playing a little bit of a game 125 00:04:27,430 --> 00:04:26,240 where you we've got crews that now that 126 00:04:29,670 --> 00:04:27,440 have been on for 127 00:04:31,990 --> 00:04:29,680 a number of hours and 128 00:04:33,590 --> 00:04:32,000 12 hours roughly they'll timeout 129 00:04:35,270 --> 00:04:33,600 we want to make sure that we don't have 130 00:04:37,189 --> 00:04:35,280 to end the operation any other than that 131 00:04:39,270 --> 00:04:37,199 so we're really trying to maximize that 132 00:04:40,870 --> 00:04:39,280 so then the process of working that with 133 00:04:45,270 --> 00:04:40,880 the nitrogen and 134 00:04:47,030 --> 00:04:45,280 helium liquid oxygen and liquid hydrogen 135 00:04:48,950 --> 00:04:47,040 the other part of it is right the beauty 136 00:04:52,390 --> 00:04:48,960 of us is we're in a test we're not going 137 00:04:54,710 --> 00:04:52,400 anywhere today and so um we don't have a 138 00:04:57,350 --> 00:04:54,720 destination our destination is is right 139 00:04:58,870 --> 00:04:57,360 here and the difference right at kennedy 140 00:05:01,189 --> 00:04:58,880 is they've got you know the orbital 141 00:05:02,870 --> 00:05:01,199 mechanics uh the their destination is to 142 00:05:05,029 --> 00:05:02,880 where they're going to go and so they 143 00:05:08,230 --> 00:05:05,039 have to work basically all those details 144 00:05:09,830 --> 00:05:08,240 in to their uh exact launch window our 145 00:05:11,350 --> 00:05:09,840 our launch window is basically when we 146 00:05:13,590 --> 00:05:11,360 start the test and and that doesn't 147 00:05:15,110 --> 00:05:13,600 matter too much today but but they do 148 00:05:17,029 --> 00:05:15,120 have a you know they have they've got a 149 00:05:19,510 --> 00:05:17,039 real time hack that they have to hit so 150 00:05:21,909 --> 00:05:19,520 they'll have uh built-in holds into 151 00:05:23,990 --> 00:05:21,919 their process and procedures down there 152 00:05:26,230 --> 00:05:24,000 and that'll inform them kind of how they 153 00:05:27,670 --> 00:05:26,240 move through the next steps 154 00:05:30,629 --> 00:05:27,680 we just are fortunate we don't have to 155 00:05:34,230 --> 00:05:32,390 great thanks so that means that we don't 156 00:05:36,070 --> 00:05:34,240 have a specific hot fire target time 157 00:05:37,430 --> 00:05:36,080 right now at this moment 158 00:05:40,070 --> 00:05:37,440 but we'll keep listening in and we'll 159 00:05:41,830 --> 00:05:40,080 provide updates uh we do know that the 160 00:05:43,670 --> 00:05:41,840 test remains to be projected within the 161 00:05:45,830 --> 00:05:43,680 test window and we believe we're within 162 00:05:47,749 --> 00:05:45,840 about 45 minutes and so uh we'll 163 00:05:56,150 --> 00:05:47,759 continue to listen in here and i'll turn 164 00:05:59,029 --> 00:05:57,670 thanks catherine and bill and we will 165 00:06:00,710 --> 00:05:59,039 come back to you in just a few minutes 166 00:06:02,629 --> 00:06:00,720 like you said to take us all the way to 167 00:06:04,790 --> 00:06:02,639 the test or sooner if you have any 168 00:06:06,070 --> 00:06:04,800 updates for us we will be listening in 169 00:06:06,950 --> 00:06:06,080 and i'll head right back to you if you 170 00:06:09,670 --> 00:06:06,960 do 171 00:06:11,510 --> 00:06:09,680 now if you are just joining us welcome 172 00:06:13,270 --> 00:06:11,520 we're live at nasa's stennis space 173 00:06:15,830 --> 00:06:13,280 center in mississippi and we're 174 00:06:18,230 --> 00:06:15,840 following the second green run hot fire 175 00:06:19,670 --> 00:06:18,240 test of the space launch system rockets 176 00:06:24,309 --> 00:06:19,680 core stage 177 00:06:28,070 --> 00:06:24,319 rocket that includes two propellant 178 00:06:31,110 --> 00:06:28,080 tanks and four rs-25 engines miles of 179 00:06:33,670 --> 00:06:31,120 cables all of the avionics electronics 180 00:06:35,749 --> 00:06:33,680 computers the brains of the rocket and 181 00:06:37,830 --> 00:06:35,759 all of the plumbing that work together 182 00:06:40,150 --> 00:06:37,840 to launch the rocket during the first 183 00:06:42,870 --> 00:06:40,160 eight minutes of the mission 184 00:06:45,350 --> 00:06:42,880 the green in green run refers to new 185 00:06:48,309 --> 00:06:45,360 untested rocket hardware so this is a 186 00:06:50,950 --> 00:06:48,319 comprehensive series of tests of all the 187 00:06:53,350 --> 00:06:50,960 core stage hardware for the sls rocket 188 00:06:56,230 --> 00:06:53,360 to demonstrate it's ready for launch 189 00:06:58,790 --> 00:06:56,240 culminating with today's hot fire 190 00:07:01,189 --> 00:06:58,800 the core stage will power every sls 191 00:07:04,070 --> 00:07:01,199 mission so this test is important not 192 00:07:06,550 --> 00:07:04,080 just for artemis one but for all future 193 00:07:09,510 --> 00:07:06,560 sls launches as well 194 00:07:12,309 --> 00:07:09,520 those rs-25 engines are expected to fire 195 00:07:14,390 --> 00:07:12,319 up shortly here at stennis space center 196 00:07:24,550 --> 00:07:14,400 before that happens let's get a closer 197 00:07:29,909 --> 00:07:27,189 super heavy lift rocket and provides the 198 00:07:33,189 --> 00:07:29,919 foundation for human exploration and 199 00:07:35,430 --> 00:07:33,199 scientific missions to the moon mars and 200 00:07:38,309 --> 00:07:35,440 beyond 201 00:07:41,830 --> 00:07:38,319 powered by two solid rocket boosters and 202 00:07:44,550 --> 00:07:41,840 four rs-25 engines this rocket provides 203 00:07:47,350 --> 00:07:44,560 unprecedented power and capability 204 00:07:50,150 --> 00:07:47,360 designed to reach 23 times the speed of 205 00:07:53,589 --> 00:07:50,160 sound and an altitude of more than 100 206 00:07:57,189 --> 00:07:53,599 miles in just over 8 minutes offering 207 00:07:59,990 --> 00:07:57,199 more energy volume capacity and payload 208 00:08:02,550 --> 00:08:00,000 mass than any rocket built today under 209 00:08:05,270 --> 00:08:02,560 the launch abort system orion and the 210 00:08:07,749 --> 00:08:05,280 upper stage and between two solid rocket 211 00:08:10,629 --> 00:08:07,759 boosters is the heart of every sls 212 00:08:15,430 --> 00:08:10,639 configuration the core stage towering 213 00:08:18,950 --> 00:08:15,440 212 feet with a diameter of 27.6 feet 214 00:08:23,029 --> 00:08:18,960 and storing 537 000 gallons of liquid 215 00:08:26,150 --> 00:08:23,039 hydrogen and 196 000 gallons of liquid 216 00:08:28,230 --> 00:08:26,160 oxygen this is the world's largest core 217 00:08:30,790 --> 00:08:28,240 stage ever built 218 00:08:33,670 --> 00:08:30,800 the core stage for artemis one fires up 219 00:08:36,550 --> 00:08:33,680 for the first time at nasa's historic v2 220 00:08:41,350 --> 00:08:38,949 the core stage was designed by nasa's 221 00:08:44,470 --> 00:08:41,360 sls program at our marshall space flight 222 00:08:46,790 --> 00:08:44,480 center in huntsville alabama then built 223 00:08:48,870 --> 00:08:46,800 by lead contractor boeing using 224 00:08:50,710 --> 00:08:48,880 state-of-the-art manufacturing just down 225 00:08:53,509 --> 00:08:50,720 the road at nasa's mishu assembly 226 00:08:55,990 --> 00:08:53,519 facility in my hometown new orleans and 227 00:08:58,230 --> 00:08:56,000 it includes engines manufactured by 228 00:09:01,269 --> 00:08:58,240 aerodyn aerojet rocketdyne with 229 00:09:04,710 --> 00:09:01,279 contributions from more than 1100 large 230 00:09:07,110 --> 00:09:04,720 and small businesses in 44 states 231 00:09:09,829 --> 00:09:07,120 it was shipped up here onto stennis on 232 00:09:12,230 --> 00:09:09,839 the pegasus barge in january of last 233 00:09:14,870 --> 00:09:12,240 year and then installed on the b2 test 234 00:09:16,790 --> 00:09:14,880 stand where you see it here today 235 00:09:19,350 --> 00:09:16,800 engineers then begin activating the 236 00:09:21,750 --> 00:09:19,360 stage's components one by one and taking 237 00:09:24,710 --> 00:09:21,760 it through the series of tests that make 238 00:09:27,110 --> 00:09:24,720 up the green run over the past year 239 00:09:29,509 --> 00:09:27,120 each test built upon the previous one 240 00:09:31,829 --> 00:09:29,519 and added a little more complexity 241 00:09:34,630 --> 00:09:31,839 so today's hot fire builds on all of 242 00:09:37,350 --> 00:09:34,640 that work for a full test of the entire 243 00:09:39,990 --> 00:09:37,360 integrated system that will simulate all 244 00:09:50,310 --> 00:09:40,000 parts of the core stage working together 245 00:09:55,990 --> 00:09:53,030 today's test will take us from extreme 246 00:09:58,470 --> 00:09:56,000 cold to extreme hot as the team loads 247 00:10:00,710 --> 00:09:58,480 cryogenic our super cold propellants 248 00:10:02,710 --> 00:10:00,720 into the fuel tanks and then fires up 249 00:10:05,430 --> 00:10:02,720 the engines to drain the propellant from 250 00:10:07,910 --> 00:10:05,440 the tanks to simulate launch 251 00:10:10,550 --> 00:10:07,920 now the hottest part of the test today 252 00:10:12,630 --> 00:10:10,560 will be those four rs-25 engines at the 253 00:10:15,829 --> 00:10:12,640 bottom of the core stage 254 00:10:18,550 --> 00:10:15,839 these rs-25s we are testing today are 255 00:10:21,110 --> 00:10:18,560 repurposed from the shuttle program 256 00:10:23,590 --> 00:10:21,120 these four engines flew on some pretty 257 00:10:25,750 --> 00:10:23,600 iconic shuttle missions including one of 258 00:10:28,389 --> 00:10:25,760 the hubble space telescope servicing 259 00:10:31,670 --> 00:10:28,399 missions the historic return to space of 260 00:10:34,150 --> 00:10:31,680 mercury astronaut and senator john glenn 261 00:10:38,150 --> 00:10:34,160 six flights to the space station and the 262 00:10:40,550 --> 00:10:38,160 final shuttle space mission in 2011. 263 00:10:43,030 --> 00:10:40,560 so you can trace a direct line from that 264 00:10:45,430 --> 00:10:43,040 final shuttle flight to the first flight 265 00:10:46,870 --> 00:10:45,440 of sls 266 00:10:49,670 --> 00:10:46,880 we've worked with our partners at 267 00:10:51,829 --> 00:10:49,680 aerojet rocketdyne to upgrade the 16 268 00:10:54,949 --> 00:10:51,839 shuttle main engines which will power 269 00:10:58,230 --> 00:10:54,959 the first four artemis flights 270 00:11:00,069 --> 00:10:58,240 and now we're building 24 new engines 271 00:11:02,790 --> 00:11:00,079 using 3d printing and other 272 00:11:06,150 --> 00:11:02,800 manufacturing innovations to reduce cost 273 00:11:08,550 --> 00:11:06,160 complexity and manufacturing time 274 00:11:10,550 --> 00:11:08,560 of course all of this work is building 275 00:11:12,949 --> 00:11:10,560 towards that artemis one launch from 276 00:11:15,030 --> 00:11:12,959 kennedy space center later this year 277 00:11:17,430 --> 00:11:15,040 here's a closer look at that mission and 278 00:11:20,470 --> 00:11:17,440 how it paves the way for future 279 00:11:21,509 --> 00:11:20,480 exploration beyond 280 00:11:22,470 --> 00:11:21,519 three 281 00:11:27,110 --> 00:11:22,480 two 282 00:11:32,150 --> 00:11:29,509 artemis 1 will lift off from launch pad 283 00:11:35,350 --> 00:11:32,160 39b at nasa's kennedy space center in 284 00:11:37,670 --> 00:11:35,360 florida with 8.8 million pounds of 285 00:11:39,829 --> 00:11:37,680 thrust provided by the most powerful 286 00:11:43,110 --> 00:11:39,839 rocket in the world our space launch 287 00:11:46,150 --> 00:11:43,120 system rocket or sls the uncrewed flight 288 00:11:48,870 --> 00:11:46,160 will be the first integrated test of sls 289 00:11:50,870 --> 00:11:48,880 our new orion spacecraft and exploration 290 00:11:53,350 --> 00:11:50,880 ground systems at kennedy 291 00:11:57,269 --> 00:11:53,360 artemis one will send orion beyond the 292 00:12:00,550 --> 00:11:57,279 moon 280 000 miles from earth farther 293 00:12:02,710 --> 00:12:00,560 than any human spacecraft has ever flown 294 00:12:04,470 --> 00:12:02,720 this is not nasa doing this this is the 295 00:12:06,550 --> 00:12:04,480 united states of america doing this this 296 00:12:08,470 --> 00:12:06,560 program the artemis program and there 297 00:12:10,550 --> 00:12:08,480 are companies all across our country 298 00:12:11,990 --> 00:12:10,560 that have a part in it so there is kind 299 00:12:13,750 --> 00:12:12,000 of this wave of excitement being 300 00:12:15,430 --> 00:12:13,760 generated just by saying we're going 301 00:12:17,110 --> 00:12:15,440 back to the moon 302 00:12:19,350 --> 00:12:17,120 after the upper stage of the rocket 303 00:12:21,269 --> 00:12:19,360 separates from orion the upper stage 304 00:12:23,110 --> 00:12:21,279 will deploy small satellites over 305 00:12:24,550 --> 00:12:23,120 several days to perform science 306 00:12:25,829 --> 00:12:24,560 experiments and technology 307 00:12:28,310 --> 00:12:25,839 demonstrations 308 00:12:30,389 --> 00:12:28,320 orion will make its multi-day outbound 309 00:12:32,550 --> 00:12:30,399 trip to the moon propelled by a service 310 00:12:33,590 --> 00:12:32,560 module provided by the european space 311 00:12:35,750 --> 00:12:33,600 agency 312 00:12:38,389 --> 00:12:35,760 engineers will test orion's systems on 313 00:12:41,190 --> 00:12:38,399 the way to the moon then orion will fly 314 00:12:43,350 --> 00:12:41,200 about 60 miles above the lunar surface 315 00:12:45,430 --> 00:12:43,360 using the moon's gravity and engines on 316 00:12:47,430 --> 00:12:45,440 the surface module to enter a lunar 317 00:12:49,829 --> 00:12:47,440 orbit 318 00:12:52,470 --> 00:12:49,839 after about a month and a total distance 319 00:12:55,269 --> 00:12:52,480 of over a million miles orion will 320 00:12:58,389 --> 00:12:55,279 return home faster and hotter than any 321 00:13:01,590 --> 00:12:58,399 spacecraft has before a primary goal of 322 00:13:04,310 --> 00:13:01,600 artemis 1 ensure orion safely returns to 323 00:13:06,389 --> 00:13:04,320 earth before we fly with humans when we 324 00:13:09,110 --> 00:13:06,399 do we'll build our capability for 325 00:13:11,269 --> 00:13:09,120 sustainable lunar exploration preparing 326 00:13:15,269 --> 00:13:11,279 us for missions farther into the solar 327 00:13:19,350 --> 00:13:17,110 initially what we'd like to do is start 328 00:13:20,629 --> 00:13:19,360 establishing a presence on the moon so 329 00:13:22,550 --> 00:13:20,639 we're going to establish going back 330 00:13:25,110 --> 00:13:22,560 there on a regular basis and then we'll 331 00:13:27,509 --> 00:13:25,120 end up setting up gateway and we would 332 00:13:31,030 --> 00:13:27,519 launch to the gateway and from gateway 333 00:13:35,350 --> 00:13:33,430 we are there for you know weeks months 334 00:13:36,710 --> 00:13:35,360 on end and there we're gonna be able to 335 00:13:38,710 --> 00:13:36,720 test out all the hardware and the 336 00:13:41,189 --> 00:13:38,720 habitats and the hatches and the suits 337 00:13:44,150 --> 00:13:41,199 and the rovers that'll allow us to prove 338 00:13:47,110 --> 00:13:45,750 the moon will lead the way to mars and 339 00:13:48,530 --> 00:13:47,120 we should be there you know within the 340 00:13:53,189 --> 00:13:48,540 next couple decades 341 00:13:56,870 --> 00:13:54,710 just amazing 342 00:13:58,550 --> 00:13:56,880 and now we are going to hand things over 343 00:14:00,829 --> 00:13:58,560 to catherine and bill again in the 344 00:14:03,509 --> 00:14:00,839 control center 345 00:14:05,670 --> 00:14:03,519 catherine thanks lee we are in the 346 00:14:07,590 --> 00:14:05,680 secondary test control 347 00:14:09,350 --> 00:14:07,600 and uh outside the control room here 348 00:14:11,509 --> 00:14:09,360 listening in so that we can provide you 349 00:14:13,910 --> 00:14:11,519 updates uh bill can you give us an 350 00:14:16,230 --> 00:14:13,920 update on how things are progressing 351 00:14:18,790 --> 00:14:16,240 yeah so they're uh in the process now of 352 00:14:21,350 --> 00:14:18,800 uh going through the final checks are 353 00:14:23,750 --> 00:14:21,360 everything's really nicely 354 00:14:25,910 --> 00:14:23,760 going really great today so uh 355 00:14:27,110 --> 00:14:25,920 everything's right on schedule nominal 356 00:14:28,550 --> 00:14:27,120 they're trying to do this thing what 357 00:14:29,829 --> 00:14:28,560 they call right now is jump the clock 358 00:14:31,430 --> 00:14:29,839 which is trying to work it a little bit 359 00:14:33,509 --> 00:14:31,440 ahead so they're in the process of 360 00:14:35,030 --> 00:14:33,519 resetting the clock and making sure that 361 00:14:36,710 --> 00:14:35,040 when they get to that 10 minute point 362 00:14:38,150 --> 00:14:36,720 that it doesn't continue to count down 363 00:14:40,150 --> 00:14:38,160 because that's that's where they have to 364 00:14:41,990 --> 00:14:40,160 go that pole well ahead of that so 365 00:14:44,949 --> 00:14:42,000 they're working on setting that stuff up 366 00:14:45,829 --> 00:14:44,959 right now 367 00:14:48,230 --> 00:14:45,839 all right 368 00:14:50,710 --> 00:14:48,240 so we'll continue to stand by and listen 369 00:14:52,550 --> 00:14:50,720 and provide updates and as we mentioned 370 00:14:55,350 --> 00:14:52,560 earlier the team previously conducted a 371 00:14:57,030 --> 00:14:55,360 hot fire test in january the engines did 372 00:14:59,670 --> 00:14:57,040 shut down earlier than planned during 373 00:15:01,110 --> 00:14:59,680 that test but the january 16th test 374 00:15:03,430 --> 00:15:01,120 successfully completed several 375 00:15:04,949 --> 00:15:03,440 operations for the first time 376 00:15:07,030 --> 00:15:04,959 they were able to transition to the 377 00:15:08,470 --> 00:15:07,040 automated launch sequence 378 00:15:11,030 --> 00:15:08,480 operated by the core stage flight 379 00:15:12,550 --> 00:15:11,040 computer and the green run test software 380 00:15:13,910 --> 00:15:12,560 they completed the terminal countdown 381 00:15:15,350 --> 00:15:13,920 sequence that is like the launch 382 00:15:16,870 --> 00:15:15,360 countdown 383 00:15:18,629 --> 00:15:16,880 they also pressurized the tanks and 384 00:15:20,389 --> 00:15:18,639 delivered the propellant to the engines 385 00:15:22,870 --> 00:15:20,399 and demonstrated the performance of the 386 00:15:26,710 --> 00:15:22,880 core stage as main propulsion system 387 00:15:28,150 --> 00:15:26,720 firing the engines at 109 power and they 388 00:15:30,310 --> 00:15:28,160 operated the thrust vector control 389 00:15:33,110 --> 00:15:30,320 system that steers the engines 390 00:15:35,829 --> 00:15:33,120 so it's a smooth countdown so far today 391 00:15:37,829 --> 00:15:35,839 and we'll keep standing by we'll take a 392 00:18:58,980 --> 00:15:37,839 pause for here for a moment and we'll 393 00:18:58,990 --> 00:20:23,350 [Applause] 394 00:20:27,029 --> 00:20:26,230 the b1 b2 test stand that you're seeing 395 00:20:29,110 --> 00:20:27,039 there 396 00:20:31,909 --> 00:20:29,120 is a dual position vertical firing 397 00:20:34,630 --> 00:20:31,919 facility with the b1 398 00:20:37,669 --> 00:20:34,640 side equipped for single engine tests 399 00:20:39,270 --> 00:20:37,679 and the b2 side designed for 400 00:20:41,230 --> 00:20:39,280 rocket stages 401 00:20:44,549 --> 00:20:41,240 the stand is anchored to the ground with 402 00:20:46,070 --> 00:20:44,559 144 feet of steel and concrete 403 00:20:49,750 --> 00:20:46,080 we talked a little bit about the history 404 00:20:51,510 --> 00:20:49,760 of the rs25 engines and the b2 stand 405 00:20:53,510 --> 00:20:51,520 which is where the sls core stage is 406 00:20:55,029 --> 00:20:53,520 secured now also has quite a bit of 407 00:20:57,590 --> 00:20:55,039 history 408 00:21:00,070 --> 00:20:57,600 it was used in the 1960s to test saturn 409 00:21:02,390 --> 00:21:00,080 v rocket stages that carried humans to 410 00:21:04,230 --> 00:21:02,400 the moon during the apollo program 411 00:21:06,789 --> 00:21:04,240 and the space shuttle main propulsion 412 00:21:08,710 --> 00:21:06,799 test article consisting of 413 00:21:10,950 --> 00:21:08,720 an external tank and three main engines 414 00:21:16,149 --> 00:21:10,960 linked together with a simulated shuttle 415 00:21:18,950 --> 00:21:16,159 orbiter was also tested on the v2 stand 416 00:21:21,350 --> 00:21:18,960 the b2 stand has been modified to test 417 00:21:23,029 --> 00:21:21,360 the sls core stage for the artemis 418 00:21:24,230 --> 00:21:23,039 program that will return humans to the 419 00:21:26,950 --> 00:21:24,240 moon 420 00:21:29,029 --> 00:21:26,960 with a new steel superstructure added 421 00:21:32,149 --> 00:21:29,039 for testing the sls core stage the stand 422 00:21:33,669 --> 00:21:32,159 is now almost 350 feet high 423 00:22:19,909 --> 00:21:33,679 ranking it as one of the tallest 424 00:22:23,669 --> 00:22:22,230 for a little bit more about the rs25 425 00:22:29,029 --> 00:22:23,679 engines 426 00:22:30,710 --> 00:22:29,039 size of a compact car if the engine were 427 00:22:33,430 --> 00:22:30,720 turned on its side 428 00:22:35,430 --> 00:22:33,440 standing up they are each 14 feet tall 429 00:22:37,350 --> 00:22:35,440 and eight feet in diameter 430 00:22:39,350 --> 00:22:37,360 they each weigh about eight thousand 431 00:22:41,669 --> 00:22:39,360 pounds 432 00:22:44,510 --> 00:22:41,679 the rs-25 is designed to operate in 433 00:22:47,190 --> 00:22:44,520 extreme temperatures from negative 434 00:22:49,990 --> 00:22:47,200 423 degrees fahrenheit to 435 00:22:52,230 --> 00:22:50,000 6000 degrees fahrenheit and as we 436 00:22:55,590 --> 00:22:52,240 mentioned today's test will go from 437 00:22:57,990 --> 00:22:55,600 extreme cold to extreme hot 438 00:22:59,110 --> 00:22:58,000 when the hot gases exit the rs-25s 439 00:23:01,590 --> 00:22:59,120 nozzle 440 00:23:04,070 --> 00:23:01,600 they travel at 13 times the speed of 441 00:23:06,710 --> 00:23:04,080 sound which is fast enough to travel 442 00:23:09,590 --> 00:23:06,720 from los angeles to new york city in 443 00:23:12,549 --> 00:23:09,600 about 15 minutes 444 00:23:13,510 --> 00:23:12,559 the core stage itself stands 212 feet 445 00:23:17,430 --> 00:23:13,520 tall 446 00:23:20,390 --> 00:23:17,440 and at a diameter of 27.6 feet and 447 00:25:40,070 --> 00:23:20,400 weighs about 2.3 million pounds when 448 00:25:45,590 --> 00:25:41,990 so the next major milestone coming up 449 00:25:47,110 --> 00:25:45,600 will be the pull for the terminal count 450 00:25:48,310 --> 00:25:47,120 it's the last 10 minutes of the 451 00:25:50,230 --> 00:25:48,320 countdown 452 00:25:51,830 --> 00:25:50,240 bill can you tell us a little bit about 453 00:25:53,669 --> 00:25:51,840 what we can expect to hear during the 454 00:25:54,710 --> 00:25:53,679 terminal count 455 00:25:56,310 --> 00:25:54,720 yeah so 456 00:25:58,390 --> 00:25:56,320 just ahead of terminal account we'll 457 00:25:59,669 --> 00:25:58,400 hopefully get that call they'll do a 458 00:26:01,750 --> 00:25:59,679 poll 459 00:26:03,190 --> 00:26:01,760 which is all the members of the team 460 00:26:05,830 --> 00:26:03,200 basically getting their go for going 461 00:26:09,190 --> 00:26:05,840 into that terminal account sequencer and 462 00:26:11,990 --> 00:26:09,200 then once we actually get into it 463 00:26:14,630 --> 00:26:12,000 there's at least 500 different events 464 00:26:16,310 --> 00:26:14,640 that take place in that last 10 minutes 465 00:26:17,190 --> 00:26:16,320 so i'll not uh go through each one of 466 00:26:19,350 --> 00:26:17,200 those 467 00:26:21,190 --> 00:26:19,360 with you but i there are some uh pretty 468 00:26:23,110 --> 00:26:21,200 good ones i think that highlight you 469 00:26:24,710 --> 00:26:23,120 know kind of what what the major ones 470 00:26:26,149 --> 00:26:24,720 should be or are 471 00:26:30,310 --> 00:26:26,159 we've got 472 00:26:34,070 --> 00:26:32,789 and then we've also got 473 00:26:37,669 --> 00:26:34,080 to 474 00:26:40,710 --> 00:26:37,679 operations which is where they'll 475 00:26:42,870 --> 00:26:40,720 pressurize the hydrogen tank 476 00:26:44,230 --> 00:26:42,880 it'll start doing that on its own as 477 00:26:46,870 --> 00:26:44,240 well 478 00:26:48,870 --> 00:26:46,880 initiate ground helium spin start supply 479 00:26:50,630 --> 00:26:48,880 to the cappus so initially when the 480 00:26:52,230 --> 00:26:50,640 kappas come up they'll be running off of 481 00:26:59,909 --> 00:26:52,240 uh 482 00:27:01,029 --> 00:26:59,919 the engines when they when they come up 483 00:27:03,909 --> 00:27:01,039 as part of the place a little bit about 484 00:27:06,149 --> 00:27:03,919 what the capos are yeah so that's 485 00:27:08,230 --> 00:27:06,159 the core stage auxiliary power units 486 00:27:10,549 --> 00:27:08,240 they're variants of the uh ones that 487 00:27:12,070 --> 00:27:10,559 were flown on shuttle the difference is 488 00:27:13,909 --> 00:27:12,080 is that where those were hydrazine 489 00:27:15,190 --> 00:27:13,919 powered uh these are basically runoff 490 00:27:17,510 --> 00:27:15,200 inert gas 491 00:27:19,590 --> 00:27:17,520 and then into hydrogen off of the 492 00:27:21,110 --> 00:27:19,600 engines when they get into the plus 493 00:27:23,590 --> 00:27:21,120 count 494 00:27:25,590 --> 00:27:23,600 so it's it's basically the 495 00:27:27,990 --> 00:27:25,600 it's basically a turbine system 496 00:27:30,870 --> 00:27:28,000 that uh spins a uh 497 00:27:32,870 --> 00:27:30,880 a pump and that pump then in turn uh 498 00:27:35,830 --> 00:27:32,880 pressurizes the uh 499 00:27:37,590 --> 00:27:35,840 the oil in that system and through a 500 00:27:39,350 --> 00:27:37,600 series of valves and commands they could 501 00:27:40,549 --> 00:27:39,360 then go ahead and actuate the actuators 502 00:27:43,350 --> 00:27:40,559 that are mounted to each of the engines 503 00:27:49,430 --> 00:27:46,549 after that we'll get into 504 00:27:51,430 --> 00:27:49,440 the liquid oxygen terminate uh and 505 00:27:52,789 --> 00:27:51,440 liquid oxygen replenish will stop that 506 00:27:53,750 --> 00:27:52,799 operation 507 00:27:54,710 --> 00:27:53,760 um 508 00:27:56,630 --> 00:27:54,720 and then 509 00:27:58,950 --> 00:27:56,640 we'll go into caffu starts and that's 510 00:28:00,789 --> 00:27:58,960 where each one of this those 511 00:28:03,590 --> 00:28:00,799 core stage auxiliary power units will be 512 00:28:05,350 --> 00:28:03,600 powered up and that takes you know on 513 00:28:06,789 --> 00:28:05,360 the order of about 30 seconds to bring 514 00:28:08,710 --> 00:28:06,799 each one of those units up they're done 515 00:28:10,310 --> 00:28:08,720 individually 516 00:28:12,950 --> 00:28:10,320 and then they they 517 00:28:15,029 --> 00:28:12,960 basically move into 518 00:28:17,350 --> 00:28:15,039 transitioning until the lox tank 519 00:28:20,789 --> 00:28:17,360 pressurization operations 520 00:28:23,269 --> 00:28:20,799 they do a tvc 521 00:28:24,310 --> 00:28:23,279 gimbal profile on helium so that's 522 00:28:25,669 --> 00:28:24,320 actually 523 00:28:27,430 --> 00:28:25,679 something different that you won't see 524 00:28:30,549 --> 00:28:27,440 in the plus count in other words we do a 525 00:28:32,630 --> 00:28:30,559 lot of actuation of the tvc system in 526 00:28:35,269 --> 00:28:32,640 that but we don't move it as far because 527 00:28:36,230 --> 00:28:35,279 of the limits we've got in the stand for 528 00:28:38,630 --> 00:28:36,240 how hard 529 00:28:39,510 --> 00:28:38,640 are you moving it relative to having you 530 00:28:42,470 --> 00:28:39,520 know the 531 00:28:44,230 --> 00:28:42,480 the engines burning at that time so in 532 00:28:46,149 --> 00:28:44,240 the pre-count we'll basically get the 533 00:28:48,549 --> 00:28:46,159 full movement the full gimbal full 534 00:28:49,909 --> 00:28:48,559 displacement and then uh once they get 535 00:28:51,909 --> 00:28:49,919 into the plus count they will not do 536 00:28:54,310 --> 00:28:51,919 that but they'll do some other things 537 00:28:55,269 --> 00:28:54,320 um and then uh after after that's 538 00:28:56,830 --> 00:28:55,279 complete 539 00:29:00,310 --> 00:28:56,840 uh they'll basically 540 00:29:02,950 --> 00:29:00,320 um bring the actuators into their null 541 00:29:06,389 --> 00:29:04,549 basically they'll go ahead and make sure 542 00:29:08,470 --> 00:29:06,399 the engines are ready to go ahead and 543 00:29:09,990 --> 00:29:08,480 start 544 00:29:12,230 --> 00:29:10,000 they will then 545 00:29:13,269 --> 00:29:12,240 transition the core stage to internal 546 00:29:15,590 --> 00:29:13,279 power 547 00:29:17,350 --> 00:29:15,600 uh they they do have what they've 548 00:29:19,669 --> 00:29:17,360 redundant inertial navigation unit 549 00:29:21,590 --> 00:29:19,679 they've got a gyrocompass alignment that 550 00:29:24,470 --> 00:29:21,600 they'll that they'll finish up 551 00:29:26,630 --> 00:29:24,480 and uh that's when we get into the next 552 00:29:28,630 --> 00:29:26,640 big sequence which is the go for the 553 00:29:31,590 --> 00:29:28,640 automated launch sequencer and that'll 554 00:29:33,269 --> 00:29:31,600 start roughly at 33 seconds 555 00:29:35,669 --> 00:29:33,279 so that's that's uh that's kind of the 556 00:29:38,789 --> 00:29:35,679 big steps to take place up to that point 557 00:29:40,950 --> 00:29:38,799 and um what's what what happens once we 558 00:29:43,190 --> 00:29:40,960 get into that als is that if we have to 559 00:29:45,430 --> 00:29:43,200 recycle and that's a that's a big deal 560 00:29:48,789 --> 00:29:45,440 it's probably not something we can 561 00:29:50,630 --> 00:29:48,799 recover from that easily on on day of um 562 00:29:53,190 --> 00:29:50,640 but ahead of that we can basically 563 00:29:54,389 --> 00:29:53,200 recycle back to the 10 minute mark 564 00:29:56,470 --> 00:29:54,399 uh and then 565 00:29:57,909 --> 00:29:56,480 it would take us probably an hour to to 566 00:29:59,750 --> 00:29:57,919 get back into position where we could go 567 00:30:02,789 --> 00:29:59,760 through it again but that that's kind of 568 00:30:05,590 --> 00:30:04,310 thank you so it sounds like the majority 569 00:30:07,510 --> 00:30:05,600 of the calls are actually going to come 570 00:30:08,549 --> 00:30:07,520 in the last five minutes of the terminal 571 00:30:10,230 --> 00:30:08,559 count 572 00:30:11,269 --> 00:30:10,240 um 573 00:30:13,269 --> 00:30:11,279 and so 574 00:30:15,590 --> 00:30:13,279 we're waiting to hear when we are ready 575 00:30:17,430 --> 00:30:15,600 for the the poll for the go no go into 576 00:30:18,950 --> 00:30:17,440 the terminal count 577 00:30:20,310 --> 00:30:18,960 so we'll stand by for a little bit here 578 00:38:28,710 --> 00:30:20,320 and then we'll come back when we have 579 00:38:33,750 --> 00:38:30,630 for the artemis one launch there will be 580 00:38:35,190 --> 00:38:33,760 a built-in hold before the go no go pull 581 00:38:37,270 --> 00:38:35,200 to go into the terminal count with the 582 00:38:39,670 --> 00:38:37,280 last 10 minutes of the countdown this 583 00:38:41,349 --> 00:38:39,680 isn't quite the same but it is similar 584 00:38:43,510 --> 00:38:41,359 the team takes a look at the data from 585 00:38:44,870 --> 00:38:43,520 the vehicle and the facility and ensures 586 00:38:47,109 --> 00:38:44,880 that everything looks good before 587 00:38:48,550 --> 00:38:47,119 proceeding into the terminal count 588 00:38:50,790 --> 00:38:48,560 so we're just a little more than 10 589 00:38:52,470 --> 00:38:50,800 minutes away from our t0 time now to 590 00:38:54,470 --> 00:38:52,480 fire up the engines 591 00:38:56,310 --> 00:38:54,480 and when those engines fire up the team 592 00:38:58,550 --> 00:38:56,320 is looking to get at least four minutes 593 00:39:00,550 --> 00:38:58,560 of data to support the test objectives 594 00:39:02,870 --> 00:39:00,560 needed to confirm that sls is ready to 595 00:39:04,870 --> 00:39:02,880 launch artemis missions from there they 596 00:39:06,390 --> 00:39:04,880 will continue to let the engines fire 597 00:39:07,990 --> 00:39:06,400 and to burn through all of the fuel in 598 00:39:09,990 --> 00:39:08,000 the tanks and possibly pick up 599 00:39:11,750 --> 00:39:10,000 additional data for some secondary test 600 00:39:13,109 --> 00:39:11,760 objectives 601 00:39:14,950 --> 00:39:13,119 during launch and ascent for artemis 602 00:39:16,710 --> 00:39:14,960 missions we expect the engines to fire 603 00:39:18,950 --> 00:39:16,720 for about eight minutes to drain the 604 00:39:20,790 --> 00:39:18,960 tanks of the propellant before what is 605 00:39:21,990 --> 00:39:20,800 uh called the main engine cutoff or 606 00:39:23,190 --> 00:39:22,000 mikko 607 00:39:24,630 --> 00:39:23,200 so 608 00:39:28,470 --> 00:39:24,640 bill tell us a little bit about what we 609 00:39:30,390 --> 00:39:28,480 can expect after hot fire starts 610 00:39:32,950 --> 00:39:30,400 okay so uh the other thing i'd say is 611 00:39:34,230 --> 00:39:32,960 i'm also listening in so we if we get to 612 00:39:36,230 --> 00:39:34,240 the point where they're gonna call for 613 00:39:38,550 --> 00:39:36,240 the poll i'll just tell you to pick it 614 00:39:40,790 --> 00:39:38,560 up at that point but so where i left off 615 00:39:43,270 --> 00:39:40,800 was with als start so that's roughly 30 616 00:39:44,950 --> 00:39:43,280 seconds before they actually start we 617 00:39:46,390 --> 00:39:44,960 would then bring on the hydrogen burn 618 00:39:48,150 --> 00:39:46,400 off igniters 619 00:39:49,670 --> 00:39:48,160 which are basically a series of flares 620 00:39:52,230 --> 00:39:49,680 that are built into the stand to pick up 621 00:39:54,069 --> 00:39:52,240 any residual hydrogen and basically 622 00:39:56,390 --> 00:39:54,079 dissipate all that 623 00:39:57,430 --> 00:39:56,400 they'll finish with the uh renew 624 00:39:59,990 --> 00:39:57,440 redundant 625 00:40:02,550 --> 00:40:00,000 alignment navigation mode 626 00:40:04,550 --> 00:40:02,560 um and then basically they go into at 627 00:40:08,150 --> 00:40:04,560 roughly six minutes 628 00:40:10,950 --> 00:40:08,160 they'll do the rs25 starts and those uh 629 00:40:12,550 --> 00:40:10,960 they bring up one at a time and uh 630 00:40:15,510 --> 00:40:12,560 roughly it's at 631 00:40:17,430 --> 00:40:15,520 five six seconds they'll start that at 632 00:40:19,670 --> 00:40:17,440 five six one second they'll be up and 633 00:40:22,230 --> 00:40:19,680 running at 100 634 00:40:25,589 --> 00:40:22,240 and uh 635 00:40:29,670 --> 00:40:25,599 with that i think we're getting ready to 636 00:40:32,150 --> 00:40:31,510 but um 637 00:40:36,829 --> 00:40:32,160 as 638 00:40:40,150 --> 00:40:36,839 of it we'll hear the 639 00:40:41,990 --> 00:40:40,160 uh basically the the the engines will 640 00:40:43,510 --> 00:40:42,000 come to 109 641 00:40:46,550 --> 00:40:43,520 thrust level 642 00:40:48,710 --> 00:40:46,560 and then we'll go into the first 643 00:40:50,950 --> 00:40:48,720 poll at 644 00:40:53,030 --> 00:40:50,960 the gimbal profile so i think what we 645 00:40:55,510 --> 00:40:53,040 should do at this point is switch over 646 00:41:01,910 --> 00:40:55,520 if we can pick that part of it up all 647 00:41:06,550 --> 00:41:04,390 correct uh time pack as the seat puncher 648 00:41:09,589 --> 00:41:06,560 steps through there reminder to 649 00:41:11,670 --> 00:41:09,599 everybody we after we get past 557 and 650 00:41:13,990 --> 00:41:11,680 after we terminate lh2 651 00:41:16,230 --> 00:41:14,000 system securing we only have two minutes 652 00:41:17,829 --> 00:41:16,240 35 seconds at full time before we have 653 00:41:19,589 --> 00:41:17,839 to recycle back 654 00:41:21,510 --> 00:41:19,599 also another reminder to everybody when 655 00:41:24,069 --> 00:41:21,520 we do the switch to internal power we 656 00:41:25,030 --> 00:41:24,079 will get the christmas tree effect on 657 00:41:27,190 --> 00:41:25,040 the uh 658 00:41:29,349 --> 00:41:27,200 avionics screen so that is 659 00:41:31,510 --> 00:41:29,359 normal that is to be 660 00:41:32,950 --> 00:41:31,520 expected so just remind everybody that 661 00:41:40,309 --> 00:41:32,960 we look at that christmas tree effect 662 00:41:43,670 --> 00:41:41,349 all right 663 00:41:44,790 --> 00:41:43,680 right sequencer on your 664 00:41:46,309 --> 00:41:44,800 on your command let's go ahead and 665 00:41:49,670 --> 00:41:46,319 initiate the terminal count sequencer 666 00:41:50,790 --> 00:41:49,680 for sub step alpha and record uct utc 667 00:41:58,550 --> 00:41:50,800 time please 668 00:41:58,560 --> 00:42:02,870 okay kecount has resolved 669 00:42:09,589 --> 00:42:05,589 and give us a utc real quick please 670 00:42:12,870 --> 00:42:11,589 copy zero seven seven twenty twenty 671 00:42:56,790 --> 00:42:12,880 seven twelve 672 00:42:56,800 --> 00:43:07,430 see my assignments 673 00:43:11,270 --> 00:43:09,030 all right it sounds like we actually 674 00:43:12,950 --> 00:43:11,280 missed the poll so we are in the 675 00:43:14,630 --> 00:43:12,960 terminal count sequence now and we are 676 00:43:56,710 --> 00:43:14,640 standing by and listening as they 677 00:43:56,720 --> 00:44:56,470 he might say man 678 00:45:00,630 --> 00:44:59,030 t-minus seven minutes 679 00:45:21,270 --> 00:45:00,640 let's place your reporters into 680 00:45:56,870 --> 00:45:24,470 and we're about six and a half minutes 681 00:46:56,630 --> 00:45:58,950 and t my six minutes starting lh2 682 00:47:28,870 --> 00:46:59,030 t minus five minutes initiating tvc spin 683 00:47:34,069 --> 00:47:31,270 yeah so so at this point uh they 684 00:47:35,910 --> 00:47:34,079 basically initiated uh kappu start 685 00:47:38,549 --> 00:47:35,920 uh and and basically those will be 686 00:47:39,990 --> 00:47:38,559 coming up on helium they'll go into a 687 00:47:42,150 --> 00:47:40,000 what we call the wiggle test which is 688 00:47:44,630 --> 00:47:42,160 where they'll gamble the engines 689 00:47:47,349 --> 00:47:44,640 um and then so so that's uh 690 00:47:49,270 --> 00:47:47,359 basically coming up here in uh 691 00:47:52,870 --> 00:47:49,280 just a couple of minutes 692 00:47:54,790 --> 00:47:52,880 uh on the on the plus side of of that 693 00:47:56,470 --> 00:47:54,800 uh you know once we get into the engine 694 00:47:57,910 --> 00:47:56,480 starts um 695 00:48:01,109 --> 00:47:57,920 t minus four minutes 696 00:48:02,870 --> 00:48:01,119 start starting l02 securing okay so l2 697 00:48:04,870 --> 00:48:02,880 is being secured now so that they're 698 00:48:08,710 --> 00:48:04,880 getting they're really moving forward in 699 00:48:08,720 --> 00:48:16,230 still roughly at t minus 700 00:48:16,240 --> 00:48:18,710 three minutes 701 00:48:22,950 --> 00:48:21,349 and so with that we should be seeing the 702 00:48:25,910 --> 00:48:22,960 um 703 00:48:30,630 --> 00:48:25,920 tvc gimbal profile here in about uh half 704 00:48:36,150 --> 00:48:33,670 basically at this point they've got uh 705 00:48:38,309 --> 00:48:36,160 the water system all turned on you can 706 00:48:40,790 --> 00:48:38,319 go see that in some of the views 707 00:48:42,230 --> 00:48:40,800 and that'll basically take care of uh 708 00:48:44,230 --> 00:48:42,240 not only the heat coming off of the 709 00:48:45,589 --> 00:48:44,240 engines but also dampen uh the 710 00:48:49,670 --> 00:48:45,599 tremendous amount of noise that will be 711 00:48:53,990 --> 00:48:51,670 as mentioned earlier hydrogen burn-off 712 00:48:56,309 --> 00:48:54,000 igniters uh will come on 713 00:48:58,069 --> 00:48:56,319 at about 12 seconds 714 00:48:59,910 --> 00:48:58,079 uh t-minus three minutes starting with 715 00:49:01,750 --> 00:48:59,920 psn4 716 00:49:04,470 --> 00:49:01,760 the uh 717 00:49:05,589 --> 00:49:04,480 navigation mode uh will be complete at 718 00:49:07,670 --> 00:49:05,599 about 10 719 00:49:08,790 --> 00:49:07,680 t minus 10 seconds 720 00:49:11,190 --> 00:49:08,800 and then 721 00:49:12,790 --> 00:49:11,200 basically the enable command for als at 722 00:49:14,870 --> 00:49:12,800 9.2 seconds 723 00:49:16,470 --> 00:49:14,880 and then we go into engine start roughly 724 00:49:18,230 --> 00:49:16,480 at six seconds 725 00:49:19,670 --> 00:49:18,240 those uh take about five seconds to come 726 00:49:21,109 --> 00:49:19,680 off the full operating 727 00:49:23,109 --> 00:49:21,119 uh pressures 728 00:49:25,190 --> 00:49:23,119 and uh basically at that point the stage 729 00:49:27,190 --> 00:49:25,200 controller we go for launch 730 00:49:28,390 --> 00:49:27,200 or go for test in this case at two 731 00:49:31,829 --> 00:49:28,400 seconds 732 00:49:36,549 --> 00:49:31,839 and um basically we go forward into our 733 00:49:39,109 --> 00:49:37,589 all right 734 00:49:56,470 --> 00:49:39,119 we're coming up on twitter again we'll 735 00:49:56,480 --> 00:50:00,790 two minus two minutes 736 00:50:04,230 --> 00:50:02,309 so a call was they just announced that 737 00:50:06,470 --> 00:50:04,240 t-minus two minutes uh which is 738 00:50:08,390 --> 00:50:06,480 basically they have finished uh the 739 00:50:09,829 --> 00:50:08,400 gimbal test with the actuators and 740 00:50:11,750 --> 00:50:09,839 they're bringing them back into the null 741 00:50:13,589 --> 00:50:11,760 position 742 00:50:16,069 --> 00:50:13,599 and then basically at this point they 743 00:50:20,470 --> 00:50:16,079 basically are getting ready for powering 744 00:50:24,470 --> 00:50:23,510 again core stage transitions to internal 745 00:50:26,710 --> 00:50:24,480 power 746 00:50:28,069 --> 00:50:26,720 at roughly a minute and 30 seconds out t 747 00:50:30,549 --> 00:50:28,079 minus one thirty switching internal 748 00:50:38,069 --> 00:50:32,950 and then uh if renewed our compass 749 00:50:44,950 --> 00:50:40,549 and then we'll have to go for uh als and 750 00:50:44,960 --> 00:50:57,190 that t-minus 33 seconds 751 00:51:18,230 --> 00:50:58,710 t minus one minute following personnel 752 00:51:26,870 --> 00:51:19,910 basically the water system has come on 753 00:51:30,950 --> 00:51:29,510 all right you might think we're an als 754 00:51:33,910 --> 00:51:30,960 and you just got the 755 00:51:35,910 --> 00:51:33,920 the official start of als 756 00:51:38,870 --> 00:51:35,920 next up is the hydrogen burn-off 757 00:51:46,950 --> 00:51:38,880 igniters come on at 12 seconds before 758 00:51:46,960 --> 00:52:03,030 is on go for engine start h-boys 759 00:52:03,040 --> 00:52:57,990 in control 760 00:53:25,109 --> 00:53:00,150 for 60 seconds starting cbc profile 761 00:53:25,119 --> 00:53:42,069 okay first time we've got a fire 762 00:53:42,079 --> 00:53:58,069 i can't pull it off 763 00:53:58,079 --> 00:54:03,220 remember

01:00:35,760 personnel that takes us to page 656 all 784 01:00:43,190 --> 01:00:38,160 personnel go to page 656 to start the 785 01:00:47,030 --> 01:00:44,789 all right 786 01:00:48,470 --> 01:00:47,040 personnel um bill as you said earlier as 787 01:00:50,230 --> 01:00:48,480 we talked about earlier the team was 788 01:00:52,470 --> 01:00:50,240 hoping to get at least four minutes of 789 01:00:57,430 --> 01:00:52,480 data 790 01:00:57,440 --> 01:01:13,589 um 791 01:01:18,470 --> 01:01:15,829 all right they are proceeding with the 792 01:01:19,829 --> 01:01:18,480 their shutdown procedures now as we said 793 01:01:21,589 --> 01:01:19,839 earlier the team was hoping to get at 794 01:01:23,349 --> 01:01:21,599 least four minutes of data and they did 795 01:01:25,270 --> 01:01:23,359 get more than ten then eight minutes 796 01:01:27,030 --> 01:01:25,280 excuse me so they should have gotten 797 01:01:28,789 --> 01:01:27,040 what they need the team will obviously 798 01:01:31,270 --> 01:01:28,799 need to look at that data but based on 799 01:01:32,789 --> 01:01:31,280 what we've seen uh bill tell us more 800 01:01:35,910 --> 01:01:32,799 about what would it look like to you 801 01:01:37,589 --> 01:01:35,920 yeah so they uh clearly got the 802 01:01:39,190 --> 01:01:37,599 full duration that they were after which 803 01:01:40,950 --> 01:01:39,200 is really great news and i think you 804 01:01:42,630 --> 01:01:40,960 heard the applause they had you know the 805 01:01:44,789 --> 01:01:42,640 commander shut down which is exactly 806 01:01:47,750 --> 01:01:44,799 what they were looking for they had no 807 01:01:49,750 --> 01:01:47,760 tcc violations uh test commit criteria 808 01:01:51,829 --> 01:01:49,760 violations that would have prompted an 809 01:01:54,069 --> 01:01:51,839 early shutdown so that was really good 810 01:01:55,510 --> 01:01:54,079 news um you know clearly there's a lot 811 01:01:58,069 --> 01:01:55,520 of data now that's going to have to be 812 01:01:59,670 --> 01:01:58,079 analyzed the engineers got to see 813 01:02:02,069 --> 01:01:59,680 what worked what didn't or what needs to 814 01:02:04,950 --> 01:02:02,079 be tweaked and what doesn't but that 815 01:02:07,190 --> 01:02:04,960 said i think the applause says a lot 816 01:02:08,549 --> 01:02:07,200 about how the team feels 817 01:02:09,190 --> 01:02:08,559 you know that they got through the test 818 01:02:14,710 --> 01:02:09,200 and 819 01:02:19,349 --> 01:02:17,109 yeah so um 820 01:02:21,589 --> 01:02:19,359 there was some uh you know observed uh 821 01:02:24,069 --> 01:02:21,599 burning on the aft end uh one of the 822 01:02:25,990 --> 01:02:24,079 things that boeing had done uh pri after 823 01:02:28,630 --> 01:02:26,000 the last test was to apply 824 01:02:30,710 --> 01:02:28,640 uh a lot of extra cork to the aft end 825 01:02:32,470 --> 01:02:30,720 because we're we aren't gonna 826 01:02:34,630 --> 01:02:32,480 we didn't unfortunately with this test 827 01:02:36,950 --> 01:02:34,640 right we're not flying through uh the 828 01:02:38,230 --> 01:02:36,960 thin air as you as we ascend 829 01:02:39,349 --> 01:02:38,240 and so we knew we were going to have 830 01:02:41,190 --> 01:02:39,359 more of that and that was one of the 831 01:02:43,910 --> 01:02:41,200 reasons why they added that they also 832 01:02:45,670 --> 01:02:43,920 put a tape covering over the top of that 833 01:02:47,589 --> 01:02:45,680 we knew that you know if the tape gets 834 01:02:49,190 --> 01:02:47,599 hot enough that adhesive layer below the 835 01:02:51,430 --> 01:02:49,200 tape surface is going to start burning 836 01:02:53,349 --> 01:02:51,440 him so we clearly saw a lot of that 837 01:02:54,950 --> 01:02:53,359 but there was nothing that prompted a 838 01:02:57,510 --> 01:02:54,960 shutdown early which was which was 839 01:02:59,270 --> 01:02:57,520 really good news 840 01:03:01,190 --> 01:02:59,280 great thank you bill i think that's all 841 01:03:02,470 --> 01:03:01,200 the updates that we'll have for you here 842 01:03:04,069 --> 01:03:02,480 as the team proceeds through their 843 01:03:08,150 --> 01:03:04,079 shutdown procedures so we'll turn it 844 01:03:11,670 --> 01:03:10,549 thank you catherine congratulations to 845 01:03:13,829 --> 01:03:11,680 the team 846 01:03:16,710 --> 01:03:13,839 so as the engineers gather the data from 847 01:03:19,349 --> 01:03:16,720 today we look ahead to the next steps 848 01:03:21,510 --> 01:03:19,359 this core stage will be refurbished and 849 01:03:23,190 --> 01:03:21,520 sent by barge to our kennedy space 850 01:03:25,510 --> 01:03:23,200 center in florida 851 01:03:27,510 --> 01:03:25,520 there it will be stacked in the iconic 852 01:03:30,710 --> 01:03:27,520 vehicle assembly building with other 853 01:03:33,270 --> 01:03:30,720 elements of the sls rocket including the 854 01:03:35,349 --> 01:03:33,280 twin solid rocket boosters which our 855 01:03:37,430 --> 01:03:35,359 teams are have already begun stacking on 856 01:03:39,670 --> 01:03:37,440 the mobile launcher 857 01:03:42,069 --> 01:03:39,680 the core stage and boosters will then be 858 01:03:44,390 --> 01:03:42,079 stacked with the upper stage and the 859 01:03:46,549 --> 01:03:44,400 orion spacecraft 860 01:03:49,829 --> 01:03:46,559 all of this work putting us on track to 861 01:03:53,190 --> 01:03:49,839 roll out to launch pad 39b for a liftoff 862 01:03:54,950 --> 01:03:53,200 later this year on artemis one 863 01:03:56,150 --> 01:03:54,960 we've got several other firsts on the 864 01:03:59,029 --> 01:03:56,160 horizon 865 01:04:01,990 --> 01:03:59,039 this year the first of our commercial 866 01:04:03,990 --> 01:04:02,000 lunar payload services or clips missions 867 01:04:06,470 --> 01:04:04,000 begin with two companies delivering 868 01:04:08,870 --> 01:04:06,480 instruments to the lunar surface 869 01:04:11,029 --> 01:04:08,880 the golf cart sized viper rover will 870 01:04:14,950 --> 01:04:11,039 search for water at the moon's south 871 01:04:17,750 --> 01:04:14,960 pole and a small cubesat called capstone 872 01:04:21,430 --> 01:04:17,760 will head to the moon scouting the orbit 873 01:04:23,829 --> 01:04:21,440 to be used on later human missions 874 01:04:25,670 --> 01:04:23,839 meanwhile the hardware for the next two 875 01:04:27,829 --> 01:04:25,680 artemis missions which will carry 876 01:04:30,390 --> 01:04:27,839 astronauts to the moon is coming 877 01:04:33,270 --> 01:04:30,400 together the orion spacecraft for 878 01:04:35,990 --> 01:04:33,280 artemis ii is down at kennedy undergoing 879 01:04:38,789 --> 01:04:36,000 assembly and the spacecraft for artemis 880 01:04:40,870 --> 01:04:38,799 iii as well as the rockets for artemis 881 01:04:44,870 --> 01:04:40,880 two and three are also being 882 01:04:47,270 --> 01:04:44,880 manufactured right now at mishu 883 01:04:49,750 --> 01:04:47,280 so that wraps it up for us
